Description of the Invention: TECHNICAL FIELD OF THE INVENTION The present invention relates to a type of screw, and more particularly to a wood screw. [Prior Art] Referring to Fig. 1, a conventional wood screw 1 includes a screw head 110 and a (four) 120. The screw head iiM is for engaging with the locking tool; the rod body 120 is extended by the screw head 11 and has a parallel rod portion 124 and a tapered portion 122 formed at the end of the parallel rod portion 124. Further, a thread 13 is formed on the parallel shaft portion 124 and the tapered portion 122. * N "·, and compete for the hole, you can screw it directly into the wood. However, when the wood screw ι is inserted into the wood, the friction between the parallel rod body 124 and the thread 13 and the wood gradually increases. Need more and more screwing torque = the wood chips generated by the cutting of the thread 13G can not be discharged smoothly, and the wood is prone to cracking. In addition, for the composite material of plastic and wood chips, it has some slight elasticity and close Goodness, screw〗 (10) When locking in the continuation: Material, due to the difficulty of threading 130, it is easy to occur empty/turning.

The third thread is then engageable with the wood to provide a tensile force that prevents pullout. Therefore, the wood screws according to the present invention can be applied to lock various wood materials such as various softwoods, hardwoods, 'very hardwoods, plastic and wood chips, or soft and hard composites of resin and wood chips. In order to make the objects, features, and advantages of the present invention more apparent, the following detailed description will be made in conjunction with the accompanying drawings. [Embodiment] In the second embodiment, the wood screw of the first embodiment of the present invention comprises a screw head 210 and a rod body 22A. The screw head 21 is used to connect with the lock f tool, and the rod body 220 is extended by the screw head 21 并, and an axis 29〇 is drawn. The rod body 22 has a body portion 224, a tapered portion 222 formed at the end of the parallel rod portion 224 and tapered, and a tip end 226 formed at the end of the tapered portion 222. A third thread 230 is formed on the parallel shaft portion 224 that can be engaged with the wood (four) to provide a tensile force that prevents pullout. The wood screw 2 has a first thread 240 that extends from the tip and is formed on the tapered portion 222. Also formed on the 222 is at least one second thread (four) that is not extended by the tip, which is located between the first thread 24""-thread 23G and extends above the parallel rod portion, and the threads 230, 24, 25 () are not connected to each other.
01482-TW 201137246 % _ 述第一螺紋250的導程角（lead angle)02最大，第三 螺紋230的導程角03次之，第一螺紋240的導程角 ㊀1為最小。而比較各螺紋的外徑，係以第三螺紋230 的螺紋外徑D3為最大，第二螺紋250的螺紋外徑 D2次之，以第一螺紋24〇的螺紋外徑di為最小。01482-TW 201137246 % _ The lead angle 02 of the first thread 250 is the largest, the lead angle of the third thread 230 is 0, and the lead angle 1 of the first thread 240 is the smallest. Comparing the outer diameter of each thread, the thread outer diameter D3 of the third thread 230 is the largest, and the thread outer diameter D2 of the second thread 250 is second, and the thread outer diameter di of the first thread 24〇 is the smallest.
由於第一螺紋240具有小的導程角，在木螺絲 200旋入木材期間’可快速攫取木材表面。另外， 第二螺紋250可依使用者期望的方向快速旋入木材 中，並在第二螺紋230鎖入木材後，第二螺紋25〇 即變為具有鑽孔及切削木塊中之木纖維的功能，可 降低木螺絲200的旋入扭力，並防止木材裂開，以 達到螺絲成功鎖合，符合使用者最佳期望。除此之 外，木螺絲200較佳係包含有三個第二螺紋25〇， 對稱地形成於尖錐部分222上，其橫切面可形成三 角定位，如此，將可進一步依使用者期望的方向快 速旋入木材中，達到更佳的鎖合效果。 十 ----- ^ ^ J Q j :有類似木螺絲2GG的結構，在此相同標號標示著 相同的元件。木螺絲3〇〇在平行桿體部分 =螺紋230與螺頭21〇之間，更形成有—第四螺 :60’其螺紋的螺旋方向與第三螺紋23〇的螺 方向相同，且其牙距p4小於笛一 、孑此小於第二螺紋230的牙距 。如此，當若第三螺紋230的抗拉力不足時，第Since the first thread 240 has a small lead angle, the wood surface can be quickly picked up during the screwing of the wood screw 200 into the wood. In addition, the second thread 250 can be quickly screwed into the wood in a direction desired by the user, and after the second thread 230 is locked into the wood, the second thread 25 becomes a wood fiber having a hole and a cutting block. The function can reduce the screwing torque of the wood screw 200 and prevent the wood from cracking, so as to achieve the successful locking of the screw, in accordance with the user's best expectation. In addition, the wood screw 200 preferably includes three second threads 25〇 symmetrically formed on the tapered portion 222, and the cross-section of the wood can be formed into a triangular position, so that it can be further quickly oriented in the direction desired by the user. Screw into the wood for a better fit. Ten ----- ^ ^ J Q j : There is a structure similar to the wood screw 2GG, and the same reference numerals are used to designate the same components. The wood screw 3 is in the parallel rod body portion=the thread 230 and the screw head 21〇, and is further formed with a fourth screw: 60', the spiral direction of the thread is the same as the screw direction of the third thread 23〇, and the teeth thereof The distance from p4 is smaller than the flute, which is smaller than the pitch of the second thread 230. Thus, if the tensile force of the third thread 230 is insufficient,
01482-TW 201137246 四螺紋260可以幫助螺頭21〇沈入木材中，避免了 螺頭210無法完全下沈的情況。 參考第4、5及6圖，本發明第三實施例之木螺 絲400具有類似木螺絲3〇〇的結構，在此相同標號 標示著相同的元件。木螺絲4〇〇在平行桿體部分 上的第二螺紋230與第四螺紋26〇之間另形成有 各式的滾花，例如為滾斜花272 (見第4圖）、直花 274 (見第5圖）或者是格花276 (見第6圖）。這· 些滾花272、274、276設計可在第三螺紋230鎖入 木材後持續擴孔’以降低無牙段之桿體細的摩捧 力，進而減小木螺絲400旋入木材時.所需的扭力Γ 參考第7、8及9圖，本發明第四實施例之木螺 絲5〇〇具有類似木螺絲_的結構，在此相同桿號 標不著相同的元件。與第4、5及6圖之木螺絲_ 的不同處在於，本實施狀木螺絲500未具有第四# 螺、’文26G @其餘結構與前述實施例的木螺絲400 相同，於此不再贅述。 目士參考第1G圖，本發明第五實施例之木螺絲600 r πϋ似木螺絲200的結構.，在此相同標號標示著 目I、疋件。木螺絲600在平行桿體部分上 ::紋Γ°與螺頭210之間，更形成有-第五螺 =及其螺紋的螺旋方向與第三螺纹230的螺旋 万向相反。如Α Μ & 戈此’反向的苐五螺紋280可將沿著第01482-TW 201137246 Four threads 260 can help the screw head 21 sink into the wood, avoiding the situation where the screw head 210 cannot sink completely. Referring to Figures 4, 5 and 6, the wood screw 400 of the third embodiment of the present invention has a structure similar to that of a wood screw, and the same reference numerals are used to designate the same elements. The wooden screw 4 is further formed with various knurls between the second thread 230 and the fourth thread 26〇 on the parallel rod portion, for example, the slanting flower 272 (see Fig. 4) and the straight flower 274 (see Fig. 4). See Figure 5) or Gehua 276 (see Figure 6). These knurlings 272, 274, 276 are designed to continue to ream the third thread 230 after locking the wood to reduce the fine grip of the shaft without the teeth, thereby reducing the time when the wood screw 400 is screwed into the wood. Torque required Γ Referring to Figures 7, 8, and 9, the wood screw 5 of the fourth embodiment of the present invention has a structure similar to a wood screw _, where the same rod number does not mark the same element. The difference from the wood screws _ of the fourth, fifth and sixth figures is that the wood screw 500 of the present embodiment does not have the fourth # screw, 'the text 26G @ the rest of the structure is the same as the wood screw 400 of the previous embodiment, and no longer Narration. Referring to Fig. 1G, the wood screw 600 r π ϋ is similar to the structure of the wood screw 200 of the fifth embodiment of the present invention. Here, the same reference numerals denote the items I and 疋. The wood screw 600 is formed between the parallel rod portion and the screw head 210, and is formed with a - fifth screw = and the spiral direction of the thread is opposite to the spiral direction of the third thread 230.

According to the wood screw of the present invention, the first thread can quickly pick up the surface of the wood during the screwing of the wood screw into the wood. No.: The thread can be quickly rotated into the wood according to the direction desired by the user, and after the third thread is locked into the wood, the second thread becomes a function of the wood fiber in the drilling and cutting block, and the wood screw can be lowered.
