火災警報器本體2，是如圖3與圖4所示，藉著保護蓋16與背面板17的螺止，夾著火災感知部的一個例子的煙感知部13、控制板14、揚聲器15等的功能構件。As shown in FIG. 3 and FIG. 4, the fire alarm main body 2 is a smoke sensing unit 13, an example of a fire sensing unit, a control panel 14, a speaker 15, etc., by a screwing of the protective cover 16 and the back panel 17. Functional components.
保護蓋16是由底板16a與側板16b構成漏斗狀，將設有與背面板17螺止用的螺絲孔的柱18與背面板17疊合時，包圍並封閉開口19使異物不會從被設在背面板17的開口19進入影響到煙感知部13、控制板14、揚聲器15等功能構件的包圍壁20。The protective cover 16 is formed in a funnel shape by the bottom plate 16a and the side plate 16b, and when the column 18 and the back plate 17 provided with the screw holes for locking the back plate 17 are overlapped, the opening 19 is closed and closed so that foreign matter is not set. The opening 19 of the back panel 17 enters the surrounding wall 20 that affects the functional components such as the smoke sensing portion 13, the control panel 14, and the speaker 15.
包圍壁20，具有：從側板16b朝略正交的方向延伸出的兩個側壁部；與連接兩個側壁部的前端側的內側壁部。包圍壁20可防止螺絲等的異物從開口19進入時，滯留在包圍壁20的內側，往保護蓋16內部脫落的情況。The surrounding wall 20 has two side wall portions extending from the side plate 16b in a direction slightly orthogonal to each other, and an inner side wall portion connecting the front end sides of the two side wall portions. The surrounding wall 20 can prevent the foreign matter such as a screw from entering the inside of the surrounding wall 20 and coming off the inside of the protective cover 16 when entering the opening 19 .
在包圍壁20，限制肋22呈一體而設。限制肋22疊合在背面板17時，位在背面板17的齒部21正下的包圍壁20的側壁部(安裝方向側)的頂部朝背面板17的方向延伸。限制肋22是當相對於安裝基座3將沒有安裝電池的火災警報器本體2朝安裝方向轉動時，可使止擋片23因齒支承部8的下扣部9被朝著與安裝方向的反方向按壓時不會移動，且可使片支撐部25抵接在限制肋22，而不會在往齒部21的方向移動。該限制肋22是突出設在開口19內。In the surrounding wall 20, the restricting ribs 22 are integrally provided. When the restricting rib 22 is superposed on the back panel 17, the top portion of the side wall portion (mounting direction side) of the surrounding wall 20 directly below the tooth portion 21 of the back panel 17 extends in the direction of the back panel 17. The restricting rib 22 is such that when the fire alarm body 2 in which the battery is not mounted with respect to the mounting base 3 is rotated in the mounting direction, the stopper piece 23 can be moved toward the mounting direction by the lower buckle portion 9 of the tooth support portion 8. It does not move when pressed in the reverse direction, and the sheet supporting portion 25 can be abutted against the restricting rib 22 without moving in the direction toward the tooth portion 21. The restricting rib 22 is protruded into the opening 19.
又，在包圍壁20，限制片26呈一體而設。限制片26是從設有限制肋22的包圍壁20的側壁部(安裝方向側)朝略正交的方向延伸出的壁部、安裝方向側前端部被連接在與包圍壁20的側壁部同様的壁部而予以強化。限制片26被疊合在背面板17時，位在止擋構件24的止擋片支撐部25的正下方，且其頂部朝向安裝方向，在後方側呈平坦，在前方側形成傾斜。止擋片支撐部25是當電池被安裝在電池收納部27時，朝向轉動方向(安裝方向)傾斜變形使前方側變低，所以將限制片26的頂部斜切讓變形部退縮。Further, in the surrounding wall 20, the regulating piece 26 is integrally provided. The restricting piece 26 is a wall portion extending from a side wall portion (mounting direction side) of the surrounding wall 20 on which the restricting rib 22 is provided, in a direction slightly orthogonal to each other, and a front end portion in the mounting direction side is connected to the side wall portion of the surrounding wall 20.

When the restriction piece 26 is superposed on the back panel 17, it is positioned directly below the stopper supporting portion 25 of the stopper member 24, and its top portion faces the mounting direction, is flat on the rear side, and is inclined on the front side. When the battery is attached to the battery housing portion 27, the stopper supporting portion 25 is inclined and deformed in the rotational direction (mounting direction) to lower the front side. Therefore, the top of the restricting piece 26 is chamfered to allow the deformed portion to retract.
另一方面，沒有將電池安裝在電池收納部27時，以安裝基座3的從正上方按壓齒支承部8止擋片23時，由於止擋片支撐部25會抵接在限制片26頂部的平坦部分，所以不會被壓低，據此，將火災警報器本體2朝安裝方向轉動時，止擋片23會藉著卡止在安裝基座3的齒支承部8的下扣部9的方式，而不會更進一步地轉動、所以可防止誤將沒有安裝電池的火災警報器本體2安裝到安裝基座3的情況。On the other hand, when the battery is not attached to the battery accommodating portion 27, when the tooth supporting portion 8 stopper piece 23 is pressed from directly above the mounting base 3, the stopper piece supporting portion 25 abuts on the top of the restricting piece 26 The flat portion is not depressed, and accordingly, when the fire alarm body 2 is rotated in the mounting direction, the stopper piece 23 is locked by the lower buckle portion 9 of the tooth support portion 8 of the mounting base 3. In the manner of not rotating further, it is possible to prevent accidental attachment of the fire alarm body 2 to which the battery is not mounted to the mounting base 3.

火災警報器1有：將發報移送到外部機器的機種與不移送發報的機種的兩種機種，在移報的機器安裝有對控制板14移報用連接器33。而且作為黏貼到背面板17的機器面板41也有兩種類。本發明中，在移報的機種與不移報的機種，將機器面板41的大小設成不同，並且黏貼時所使用的導引突起36、37也設有兩種類。The fire alarm 1 includes two types of models for transferring the report to the external device and the model for not transmitting the report, and the connector 33 for the control board 14 is attached to the device for reporting. Further, there are two types of the machine panel 41 that are attached to the back panel 17. In the present invention, the size of the machine panel 41 is set to be different between the type of the report and the type of the non-reported machine, and the guide projections 36 and 37 used for the attachment are also provided in two types.
螺母保持部39是保持通過側板31的切口部42，朝直徑方向插入到內側與鎖固螺絲嵌合的防鬆螺母。而且，螺母保持部39是從中板30呈剖面字狀縱立，並且具有分別覆蓋防鬆螺母的對向的兩個端面的一對保持壁43。保持壁43為所使用的防鬆螺母的寬幅以上的高度。又，保持壁43在可插入防鬆螺母側之壁部的上端設有防鬆螺母無法簡單脫離的突起44。The nut holding portion 39 is a lock nut that is held by the notch portion 42 of the side plate 31 and inserted into the inner side to be engaged with the locking screw in the radial direction. Moreover, the nut holding portion 39 is a section from the intermediate plate 30 The figure is standing upright and has a pair of retaining walls 43 that respectively cover the opposite end faces of the locknut. The retaining wall 43 is a height above the width of the locknut used. Further, the holding wall 43 is provided with a projection 44 at which the lock nut cannot be easily detached from the upper end of the wall portion into which the lock nut can be inserted.
止擋構件24是如圖5所示，具有：在電池收納部27的電池的半圓筒狀的側面接觸的底部45，藉著與半圓筒狀的直徑方向平行而設的兩個槽隙46，使一端被支撐在電池收納部27的底部45的懸臂樑47；從懸臂樑47的自由端48朝電池收納部27的軸方向延伸的止擋片支撐部25；以及從止擋片支撐部25沿著側板31縱立的止擋片23。在止擋片23設有補強用肋49。As shown in FIG. 5, the stopper member 24 has a bottom portion 45 that is in contact with the semi-cylindrical side surface of the battery of the battery housing portion 27, and two slits 46 provided in parallel with the semi-cylindrical diameter direction. a cantilever beam 47 having one end supported by the bottom portion 45 of the battery housing portion 27, a stopper piece supporting portion 25 extending from the free end 48 of the cantilever beam 47 toward the axial direction of the battery housing portion 27, and the stopper piece supporting portion 25 A stop piece 23 standing along the side plate 31. A reinforcing rib 49 is provided in the stopper piece 23.
止擋片23是當電池沒有安裝在電池收納部27時(以下稱為沒有安裝電池時)，將火災警報器本體2安裝到安裝基座3時，在轉動火災警報器本體2的方向(以下稱為安裝方向。此外，將火災警報器本體2從安裝基座3卸下時，將轉動火災警報器本體2的方向稱之為卸下的方向。)，位在齒部21的導引部50的前側，而使止擋片23的頂部比齒支承部8的下扣部9位在更上方。The stopper piece 23 is in the direction in which the fire alarm body 2 is rotated when the battery is not attached to the battery storage portion 27 (hereinafter referred to as when no battery is attached) when the fire alarm body 2 is attached to the attachment base 3 (hereinafter In addition, when the fire alarm main body 2 is detached from the attachment base 3, the direction in which the fire alarm main body 2 is rotated is referred to as a direction of removal.), the guide portion located at the tooth portion 21. The front side of the stopper piece 23 is positioned such that the top of the stopper piece 23 is positioned higher than the lower buckle portion 9 of the tooth support portion 8.
懸臂樑47，具有：直徑比電池收納部27的半圓筒狀的半徑小的圓弧狀的樑51、與從圓弧狀的樑51延伸的平板狀的樑52。該平板狀的樑52的圓弧狀的樑51連接端的相反側的端為自由端48。The cantilever beam 47 has an arc-shaped beam 51 having a diameter smaller than a semi-cylindrical radius of the battery housing portion 27 and a flat beam 52 extending from the arc-shaped beam 51. The end on the opposite side of the connecting end of the arcuate beam 51 of the flat beam 52 is a free end 48.
接著，將電池安裝在電池收納部27時，由於圓弧狀的樑51會朝向與保護蓋16接近的方向傾斜，所以自由端48會朝與保護蓋16接近的方向沈下，並接近側板31的內側面。此時，由於在側板31的內側面側設有退避部53，所以即使自由端48接近側板31的內側面，也不會與側板31接觸並可變形。Next, when the battery is attached to the battery housing portion 27, since the arc-shaped beam 51 is inclined in a direction approaching the protective cover 16, the free end 48 sinks in a direction approaching the protective cover 16 and approaches the side plate 31. Inner side. At this time, since the escape portion 53 is provided on the inner side surface side of the side plate 31, even if the free end 48 approaches the inner side surface of the side plate 31, it does not come into contact with the side plate 31 and can be deformed.
止擋片支撐部25是從懸臂樑47的自由端48沿著側板31的內側面朝卸下的方向延伸。接著，當懸臂樑47的自由端48朝保護蓋16接近的方向下沈的同時，朝側板31的內側面變形而接近時，止擋片支撐部25會變形使得與懸臂樑47連接的位置成為最下沈的位置，而相反側的下沈則為最小。因此，止擋片23是以安裝方向為下，一面傾斜一面與保護蓋16接近。此時，止擋片23的頂部比齒支承部8的下扣部9低。此時，止擋片23的頂部比齒支承部8的下扣部9低。因此，一面將火災警報器本體2按壓在安裝基座3一面朝安裝方向旋轉時，由於齒支承部8的下扣部9會通過止擋片23的頂部與齒部21的導引部50之間，使齒部21與導引部50嵌入，所以能防止火災警報器本體2從安裝基座3落下的情況。The stopper piece supporting portion 25 extends from the free end 48 of the cantilever beam 47 in the direction in which it is removed along the inner side surface of the side plate 31. Then, when the free end 48 of the cantilever beam 47 sinks in the direction in which the protective cover 16 approaches, when the inner side surface of the side plate 31 is deformed and approaches, the stopper piece supporting portion 25 is deformed so that the position connected to the cantilever beam 47 becomes The sinking position, while the sinking on the opposite side is minimal. Therefore, the stopper piece 23 is in the mounting direction downward, and is inclined toward the protective cover 16 while being inclined. At this time, the top of the stopper piece 23 is lower than the lower buckle portion 9 of the tooth support portion 8. At this time, the top of the stopper piece 23 is lower than the lower buckle portion 9 of the tooth support portion 8. Therefore, when the fire alarm main body 2 is pressed against the attachment base 3 and rotated in the mounting direction, the lower fastening portion 9 of the tooth support portion 8 passes through the top of the stopper piece 23 and the guide portion 50 of the tooth portion 21. Since the tooth portion 21 and the guide portion 50 are fitted between each other, it is possible to prevent the fire alarm body 2 from falling from the attachment base 3.
止擋片23的頂部從安裝方向的前端到中央雖呈平坦，但卻施予倒角加工使得從中央變低的取出終端成為最低。如此，有施予倒角加工的話，將火災警報器本體2從安裝基座3取下時，由於止擋片23的頂部與齒支承部8的下扣部9的間隙寬，所以可開始順暢地轉動。Although the top of the stopper piece 23 is flat from the front end to the center in the mounting direction, the chamfering process is performed so that the take-out terminal which is lowered from the center is the lowest. When the chamfering process is performed, when the fire alarm main body 2 is removed from the attachment base 3, since the gap between the top of the stopper piece 23 and the lower buckle portion 9 of the tooth support portion 8 is wide, the smooth start can be started. Rotate in the ground.
側板31，在與以中板30的中心為中心的對角的位置設有：齒部21；將側板從內側挖薄，當止擋構件24變形時，不會對動作造成阻礙的退避部53；以及能通過停止火災警報器本體2的轉動用的鎖固螺絲的切口部42。The side plate 31 is provided with a tooth portion 21 at a position diagonal to the center of the center plate 30; a side portion is thinned from the inside; and when the stopper member 24 is deformed, the escape portion 53 which does not hinder the operation is provided. And a notch portion 42 of the locking screw that can stop the rotation of the fire alarm body 2.
齒部21，具有：從面對側板31的安裝基座3側的頂部的內預定長度的頂部往內側以預定的厚度延伸的導引部50；與將火災警報器本體2朝安裝方向轉動時，齒支承部8的下扣部9抵接，來限制火災警報器本體2進一步轉動的限制部54。The tooth portion 21 has a guide portion 50 extending from a top portion of a predetermined length of the top portion facing the mounting base 3 side of the side plate 31 toward the inner side by a predetermined thickness; and when the fire alarm body 2 is rotated in the mounting direction The lower buckle portion 9 of the tooth support portion 8 abuts to restrict the restriction portion 54 in which the fire alarm body 2 is further rotated.
接著，說明欲將沒有安裝電池的火災警報器本體2安裝到安裝基座3時的情況。Next, a case where the fire alarm main body 2 to which the battery is not mounted is attached to the mounting base 3 will be described.
由於電池未安裝力量沒有施加在止擋構件24的懸臂樑47，所以止擋片23的頂部比安裝基座3的齒支承部8的下扣部9位於上方，將火災警報器本體2朝安裝方向轉動時，止擋片23的側端面會抵到下扣部9。因此，由於火災警報器本體2無法再進一步朝安裝方向轉動，所以無法將火災警報器本體2安裝到安裝基座3。Since the battery is not mounted without the force applied to the cantilever beam 47 of the stopper member 24, the top of the stopper piece 23 is positioned above the lower buckle portion 9 of the tooth support portion 8 of the mounting base 3, and the fire alarm body 2 is mounted toward the front. When the direction is rotated, the side end surface of the stopper piece 23 abuts against the lower buckle portion 9. Therefore, since the fire alarm main body 2 cannot be further rotated in the mounting direction, the fire alarm main body 2 cannot be attached to the mounting base 3.
接著，說明將安裝了電池的火災警報器本體2安裝到安裝基座3的情況。Next, a case where the fire alarm main body 2 to which the battery is attached is attached to the mounting base 3 will be described.
將電池安裝到電池收納部27時，力量會朝向保護蓋16的方向施加在懸臂樑47，而使懸臂樑47的自由端48朝與保護蓋16接近的方向下沈的同時，變形而與側板31的內側面接近。於是，止擋片支撐部25會變形使得與懸臂樑47連接的位置成為最下沈的位置，而相反側的下沈則為最小。因此，止擋片23是以安裝方向為下，一面傾斜一面與保護蓋16接近。此時，由於止擋片23頂部的位置比齒支承部8的下扣部9位於下方，所以，齒支承部8的下扣部9通過止擋片23的頂部之上，而與齒部21的導引部50嵌入，可將火災警報器本體2安裝到安裝基座3。When the battery is attached to the battery housing portion 27, the force is applied to the cantilever beam 47 in the direction of the protective cover 16, and the free end 48 of the cantilever beam 47 is deformed toward the side close to the protective cover 16, and is deformed to the side plate. The inner side of 31 is close. Then, the stopper piece supporting portion 25 is deformed so that the position connected to the cantilever beam 47 becomes the most sinking position, and the sinking on the opposite side is the smallest. Therefore, the stopper piece 23 is in the mounting direction downward, and is inclined toward the protective cover 16 while being inclined. At this time, since the position of the top of the stopper piece 23 is located below the lower buckle portion 9 of the tooth support portion 8, the lower buckle portion 9 of the tooth support portion 8 passes over the top of the stopper piece 23, and the tooth portion 21 The guide portion 50 is embedded to mount the fire alarm body 2 to the mounting base 3.
本發明的火災警報器是藉著相對於設有齒支承部8的安裝基座3，將設有齒部21的火災警報器本體2朝安裝方向轉動，使上述齒部21嵌入上述齒支承部8的方式，將上述火災警報器本體2可裝卸地安裝在上述安裝基座3的火災警報器1，且具備有：陷入上述火災警報器本體2的背面板17所形成的電池收納部27；以及從電池的側面接觸的上述電池收納部27的底部45至上述齒部21附近，而一體形成在上述背面板17，並且將可依上述電池收納部27的電池收納狀態，將轉動軌跡朝上下方向移動，來改變與上述齒支承部8的位置關係的止擋片23形成在前端的止擋構件24。In the fire alarm device of the present invention, the fire alarm main body 2 provided with the tooth portion 21 is rotated in the mounting direction with respect to the attachment base 3 provided with the tooth support portion 8, and the tooth portion 21 is fitted into the tooth support portion.

上述止擋片23是在電池沒有被收納在上述電池收納部27的狀態下，使上述齒支承部8位在該止擋片23的轉動軌跡上，來阻止上述齒部21嵌入上述齒支承部8，在電池被收納於上述電池收納部27的狀態下，使該止擋片23的轉動軌跡朝下方移動，讓上述齒支承部8不會位在該轉動軌跡上，而使上述齒部21嵌入上述齒支承部8。如此，由於是由與安裝基座3形成一體的齒支承部8、和與火災警報器本體2的背面板17形成一體的齒部21及止擋構件24構成作為鎖住安裝使得電池未安裝的火災警報器本體2無法安裝到安裝基座3的電池鎖機構，所以只有不需電池鎖機構的零件，且不需構成電池鎖機構的組裝作業。The stopper piece 23 is configured such that the tooth support portion 8 is positioned on the rotation locus of the stopper piece 23 in a state where the battery is not housed in the battery storage portion 27, and the tooth portion 21 is prevented from being fitted into the tooth support portion. 8. In a state where the battery is housed in the battery housing portion 27, the rotation trajectory of the stopper piece 23 is moved downward, and the tooth support portion 8 is not positioned on the rotation trajectory, and the tooth portion 21 is made The tooth support portion 8 is embedded. In this manner, the tooth support portion 8 integrally formed with the attachment base 3 and the tooth portion 21 and the stopper member 24 integrally formed with the back panel 17 of the fire alarm body 2 are configured to be locked and mounted so that the battery is not mounted. Since the fire alarm main body 2 cannot be attached to the battery lock mechanism of the mounting base 3, only the parts that do not require the battery lock mechanism are required, and the assembly work of the battery lock mechanism is not required.
又，上述火災警報器本體2具有上述齒部21，並且具備：在上述齒部21的正下方形成有開口19的上述背面板17；與覆蓋上述背面板17的保護蓋16，上述保護蓋16是將電池沒有被收納在上述電池收納部27的狀態下，上述齒支承部8將上述止擋片23朝與上述安裝方向的反方向推的時候，限制朝著與上述止擋片23的上述安裝方向的反方向移動的限制肋22設在開口19內。Further, the fire alarm main body 2 includes the tooth portion 21, and includes a back plate 17 having an opening 19 formed directly below the tooth portion 21, and a protective cover 16 covering the back plate 17, the protective cover 16 In a state where the battery is not accommodated in the battery housing portion 27, the tooth support portion 8 restricts the above-described stopper piece 23 toward the above-described stopper piece 23 when the stopper piece 23 is pushed in the opposite direction to the mounting direction. A restricting rib 22 that moves in the opposite direction of the mounting direction is provided in the opening 19.
上述保護蓋16設有對應上述開口的脫落防止用包圍壁20，上述限制肋22是與上述脫落防止用包圍壁20呈一體而設。如此，由於是藉由齒支承部8的下扣部9，使得被朝與安裝方向的反方向按壓的止擋片23的下部，藉著與保護蓋16的包圍壁20設置成為一體的限制肋22，限制往安裝方向的反方向的移動，所以可防止電池未安裝時，止擋片23被朝與安裝方向的反方向按壓而斷裂的情況。The protective cover 16 is provided with a fall prevention surrounding wall 20 corresponding to the opening, and the restricting rib 22 is provided integrally with the fall prevention surrounding wall 20. In this manner, the lower portion of the stopper piece 23 which is pressed in the opposite direction to the mounting direction by the lower buckle portion 9 of the tooth support portion 8 is provided with the restriction rib which is integrally formed with the surrounding wall 20 of the protective cover 16. 22. Since the movement in the opposite direction to the mounting direction is restricted, it is possible to prevent the stopper piece 23 from being pressed in the opposite direction to the mounting direction and being broken when the battery is not mounted.
又，上述火災警報器本體2，具備：具上述齒部21的上述背面板17、與覆蓋上述背面板17的保護蓋16，上述保護蓋16設有電池沒有被收納在上述電池收納部27的狀態下，限制上述止擋片23即使從正上方被按下，也不會朝下方移動的同時，當電池被收納在上述電池收納部27的狀態下，允許上述止擋片23一面傾斜一面朝下方移動的限制片26。Further, the fire alarm main body 2 includes the back panel 17 having the tooth portion 21 and a protective cover 16 covering the back panel 17, and the protective cover 16 is provided with a battery that is not housed in the battery housing portion 27. In the state in which the stopper piece 23 is restricted from being pushed up from above, the battery is stored in the battery housing portion 27, and the stopper piece 23 is allowed to be inclined. A restriction piece 26 that moves downward.
上述保護蓋16設有對應上述開口19的脫落防止用包圍壁20，上述限制片26是與上述脫落防止用包圍壁20呈一體而設。如此，藉著齒支承部8的下扣部9被往下方向按壓的止擋片23，由於會因與被設在其下面的保護蓋16的包圍壁20成一體的限制片26頂部的平坦部分，限制往下方的移動，所以可防止止擋片23朝保護蓋16側退縮，並可防止電池未安裝的火災警報器本體2誤裝到安裝基座3的情況。The protective cover 16 is provided with a detachment preventing surrounding wall 20 corresponding to the opening 19, and the regulating piece 26 is provided integrally with the detachment prevention surrounding wall 20. Thus, the stopper piece 23 pressed by the lower buckle portion 9 of the tooth support portion 8 in the downward direction is flattened at the top of the restriction piece 26 due to the integral with the surrounding wall 20 of the protective cover 16 provided on the lower side thereof. In part, the movement to the lower side is restricted, so that the stopper piece 23 can be prevented from retracting toward the protective cover 16 side, and the case where the fire alarm main body 2 in which the battery is not mounted is prevented from being mistakenly attached to the attachment base 3.
又，上述止擋片23是朝向上端寬幅變窄。假設因設計誤差等，而強制地將電池未安裝的火災警報器本體2朝安裝方向轉動，使齒部21嵌入到齒支承部8時，由於齒部21側被作成倒角，而使止擋片23朝向上端寬幅變窄，所以可藉著將火災警報器本體2朝卸下方向轉動的方式，而容易從安裝基座3取下。Further, the stopper piece 23 is narrowed toward the upper end. It is assumed that the fire alarm main body 2 to which the battery is not attached is forcibly rotated in the mounting direction due to a design error or the like, and when the tooth portion 21 is fitted into the tooth support portion 8, the tooth portion 21 side is chamfered to make the stop Since the sheet 23 is narrowed toward the upper end, it can be easily removed from the attachment base 3 by rotating the fire alarm main body 2 in the removal direction.
接著，說明為了讓火災警報器本體2不易被盜，而利用鎖固螺絲與防鬆螺母將火災警報器本體2固定在安裝基座3。Next, in order to prevent the fire alarm main body 2 from being stolen, the fire alarm main body 2 is fixed to the attachment base 3 by a locking screw and a lock nut.
欲施予防盜時，先折斷安裝基座3的薄板部11形成切口部，再安裝到安裝處。When the anti-theft is to be applied, the thin plate portion 11 of the mounting base 3 is first broken to form a notch portion, and then mounted to the mounting portion.
接著，將防鬆螺母插入火災警報器本體2的螺母保持部39的保持壁43之間。然後，如上所述，將安裝著電池的火災警報器本體2安裝到安裝基座3。Next, the locknut is inserted between the retaining walls 43 of the nut holding portion 39 of the fire alarm body 2. Then, as described above, the fire alarm body 2 to which the battery is attached is attached to the mounting base 3.
接著，將鎖固螺絲從安裝基座3的切口部、背面板17的切口部42插入，與被插入保持壁43間的防鬆螺母螺旋固定。這樣的話，鎖固螺絲的頭部能藉著切口部42被固定。其結果，鎖固螺絲的頭部被內包在安裝基座3的切口部，即使火災警報器本體2欲朝卸下的方向轉動，鎖固螺絲的頭部會抵在安裝基座3，使火災警報器本體2不能轉動，而可防止被盜。Next, the locking screw is inserted from the notch portion of the attachment base 3 and the notch portion 42 of the back panel 17, and is screwed to the lock nut inserted between the holding walls 43. In this case, the head of the locking screw can be fixed by the cutout portion 42. As a result, the head of the locking screw is wrapped around the notch portion of the mounting base 3, and even if the fire alarm body 2 is to be rotated in the direction of removal, the head of the locking screw will abut against the mounting base 3, The fire alarm body 2 cannot be rotated to prevent theft.
在本發明的螺母保持部39，由於是藉著防鬆螺母61的寬幅以上高度的字狀的保持壁43，保持防鬆螺母61的兩個端面，所以將鎖固螺絲62鎖緊在防鬆螺母61時，即使對防鬆螺母61施加旋轉的力，也可藉著保持壁43予以保持，並可防止防鬆螺母61的旋轉。In the nut holding portion 39 of the present invention, the height of the lock nut 61 is higher than the width of the lock nut 61. The retaining wall 43 of the shape retains both end faces of the locknut 61, so that when the lock screw 62 is locked to the locknut 61, even if a force of rotation is applied to the locknut 61, the retaining wall 43 can be retained by the retaining wall 43. It is held and the rotation of the locknut 61 can be prevented.
又，由於在插入保持壁43的防鬆螺母側的壁部設有突起44，所以防鬆螺母61即使以鎖固螺絲62鎖緊，也可防止防鬆螺母61從保持壁43脫落的情況。Further, since the projection 44 is provided on the wall portion of the retaining wall 43 that is inserted into the retaining wall 43, the lock nut 61 can be prevented from falling off from the retaining wall 43 even if the lock nut 61 is locked by the lock screw 62.
