Door-shaped money key with cushioning effect. [Prior art] 15 The conventional door type Lai 1 is roughly shown in Figure 2 in design. A door panel 11 can be installed on the door frame 12 of the cabinet. The above-mentioned door hinge i includes: The door frame mounting unit M on the door frame 12, a fascia board fixing base 14 fixedly mounted on the fascia plate n, and a coupling mechanism 2 that connects the door frame mounting early π 13 and the door panel fixing base 14. Wherein, the door frame mounting unit 13 has two first and second spaced-apart wing plates ⑶, and the door panel fixing seat ^ has two upper and lower second wing plates ⑷ 'and-positioned between the second wing plates 141 The backing piece 142, and the linking mechanism 2 includes: a linking member 2-a deflection member 22, a torsion spring, and four pivots 24, 25'26, 27 ', wherein the tops of the pivots 26, 27 are connected to form a U-shaped rod. 20 The connecting member 21 has two protruding pieces 211 spaced up and down. One of the fulcrum ends 212 of the protruding pieces 211 extends into the first fin 131 μ, and is combined with the door frame mounting unit 13 by the pivot 24. A swinging end 213 extends into the second wing 141, and the pivot member and the door plate-shaped seat M are connected to each other. The deflection member 22 has two spaced-apart cannulas 221 and 222, and i cannula 22i. The elastic projection 223 of which the cannula 221 extends into the first fin 131 and is combined with the door frame mounting unit 13 by the pivot 25, and another 5 insert s 222 extends between the second fins 141. Fortunately, it is connected to the door panel seat 14 by 27. The elastic projection 223 has a bearing surface 224 and a flat surface 225. The torsion spring 23 is pivoted on the pivot shaft, and has a fixed foot 231 which bears on the door frame mounting unit 13, and ― The abutting leg 232 on the deflecting member 22 is supported. When the conventional door-type hinge 1 is in an open position as shown in FIG. 2, the heel surface 224 of the deflection member 22 is pressed against the pressure supporting leg of the torsion spring 23 to make the torsion spring 23 in a compressed shape and f product resetting force. At this time, the positioning support piece 142 of the door panel fixing seat 14 is abutted on the two protruding pieces 211 of the connecting member M, and is connected across the pivot 25 and the center of the pivoting deflection member 22. * When the user applies ό | Μ | Η ο ", small η to the door panel 11 and the door hinge 1 is switched from the open position in FIG. 2 to a waste closed position in FIG. 3, the pivot shaft 26 will start with In addition, the pivot 24 is a fulcrum downward to the bottom of the figure. As the two pivots 26 and 27 are identical—the metal rods extend, and the extension distance between the extension shafts 25 and 27 is not changed due to the deflection member 22. Therefore, when the pivot 26 is swung below the figure, the other-the pivot 27 will be restrained, and the swivel will be swept upwards, so that the deflecting member 22 will gradually swing with the pivot 25 = the fulcrum. When the abutment surface m and the flat abutment surface 225 of the deflection member 22 are bombarded = the ends correspond to the thin feet 232 of the torsion spring 23, the deflection member 22 will be pivoted by the pivoting force 2 23 The point swings quickly, and the straight plate 11 # is set in front of the door frame 12. ，、、、 In order to achieve the purpose of automatic door closing through the cooperation of the torsion spring M and others in the design of the 叙 -shaped chain, but when the door-type hinge j is switched from the M241479 open position to the closed position, the The torsion spring 23 releases the elastic force quickly and obstructively, causing the door panel n to quickly and directly collide with the door frame 12, which is not ideal in use. [New content] The purpose of this new model is to provide a door panel that can be slowly and automatically leaned against the door frame, thereby preventing the installed door panel from closing quickly: a door hinge that hits the door frame. The door hinge of the new type includes: a tenth frame element with two up and down intervals, a door panel with two up and down intervals, a connecting plate, and a buffer mechanism. The linking mechanism includes:-linking members,-15 offsets, which can be pivotally installed between the first and second wings, and-when the door hinge is switched from the open position to the closed position, The door cage is closed to the door frame installation unit. The buffer mechanism includes: an oil placed on the door frame installation unit, a linkage member, and two buffer pivots, in which the ㈣Μ # is a cylinder shaft that retracts, and the linkage The pieces have straight protrusions spaced apart from each other. The above-mentioned swinging parts are erected on the deflection piece by means of-support = and two # among the buffer habitat shafts, and the straight protrusions oscillate. The other of the trailing shafts is pivotally connected to the cylinder shaft. 20 When the = type hinge is switched from the open position to the closed position, the swinging rotating member will drive the oil by the linking member-to provide the temperature resistance when closing the door. [Action] [Embodiment] The foregoing and other technical contents, features, and effects of the present invention will be clearly understood in the detailed description of the preferred embodiment of 7 M241479 with a δ 芩 examination scheme. See Figures 4 and 5 'The preferred implementation of the new door hinge is also installed between a door panel 11 and a door frame 12' and can be in an open position and a closed position = change 'The above door hinge includes:-installed in the door frame The door frame mounting unit 3 on the 12—the door panel fixing seat 4 fixedly coupled to the door panel 11—the connecting mechanism 5 and a buffer mechanism 6. 10 15 The door frame mounting unit 3 includes:-a fixed base plate 3 fixedly mounted on the door frame 12-a mounting base 32 having a cross-section in a cross section,-a latch base fixedly coupled to the mounting base 32 and facing the fixed base plate 31 And a latching block 34 mounted on the left side of the latching bracket 33 with a spring load, wherein the fixing base 31 has a latching edge 3U and a latching hole 312.

The deflection member 55 has two spaced-apart tubular shaft insertion portions 55-a body portion 552 connected in an arc shape between the shaft insertion portions 551 and two pieces protruding from the body portion and spaced apart from each other. There is a pivot ear 553 provided with a -axis pivot hole. The third pivot shaft 56 is inserted through the deflection member, and the-and-first fins 321 of the shaft tube portion 551 are called, and the fourth pivot shaft 57 is inserted through the other shaft insertion portion 551, and the deflection member 55 is pivotally inserted between the second wings 41. The torsion spring 54 has a fixed leg 541 bridged between the supporting piece 512 and the second pivot shaft 53, and an expansion leg 542 abutting on the main body portion 552 of the deflection member 55. In the unstressed state, the fixed leg 541 and the expanded leg 542 of the torsion spring are in a close-fitting shape, that is, the angle between two 9 M241479 persons is small, and when the torsion spring 54 is under stress Under the state, the missing angle between the feet 54 and 542 on the second floor will gradually expand and thus the resetting force 10 15 will be accumulated, including-the cymbals Η lying between the latch wings 331 lying on the latch seat 33, Two _ 62 passing through the positioning holes 323 of the latch seat 33, a linkage 63, and two buffer pivots 64, 65. Among them, the hydraulic cylinder 61 is also filled with an oil tank body 6U, and a cylinder shaft 612 that can be protruded and retracted along the axis of the mad body 6 mil. Among them, the green body 611 has a positioning corresponding to the mounting seat 32 The fixed end ㈣ of the hole 323 through which the pins 62 pass / the cylinder shaft 612 has an actuating end 614 away from the cylinder body ,, and the linkage 63 has a swinging portion 631 and a straight protruding portion which are spaced apart. The part 631 is a solid design, which extends between the inserting ears 553 of the deflection member 55, and connects the linking member 63 and the deflection member 55 by passing through the pivot ears 553 and the buffer frame shaft of the swinging portion 631. The straight protrusion 632 is composed of two pieces of upper and lower pieces so that the operating end 614 of the cylinder shaft 612 is extended and connected by the buffer pivot 65. 20 Qian Zhishu said that it was installed on the door frame. When the door hinge of the new model is in the open position shown in FIG. 5, the dog piece 511 of the connecting piece 51 rests on the positioning support of the door panel fixing seat 4. The two feet 54 of the piece a 2 of the elastic impulse 54 and 542 are expanded and thus stored: the force of the bit. At this time, the cylinder shaft 612 of the hydraulic cylinder 61 is in a retracted position, that is, the cylinder shaft 612 of the hydraulic cylinder 61 is pulled and pulled, and the buffer is still near the cylinder 611 of the hydraulic cylinder 61. In conjunction with Fig. 6 'When the new type η hinge is to be turned from the open position of Fig. 5 to 10 5 to the closed position of Fig. 6, the door plate fixing seat 4 is also leaned toward the door frame mounting unit 3, and the heart: force F' Jing 54 will release the accumulated resetting force, so that the torsion spring shaft 52 as the fulcrum will gradually move toward the 5th axis of Fig. 5t. J-axis 53 will move to the fourth pivot shaft 57 and Π plate fixing. The seat 4 and the deflector support 1 rotate in a relative direction. When the deflection of the ten pinch is based on the second pivot axis 56 as the fulcrum, the lug 553 a protruding from the self-speaking 552 and the body portion of the human cow 55 swings in the direction of the arrow of the distance β 5, and therefore the swing of the link 63 The straight projection of the part 631 in the same direction of 10 pieces 63 and the cylinder shaft 612 are more than the linkage i Zhuo I I ^ 鳊 鳊 614, so when the cylinder shaft 612 ^ swing part 631 swings downward, and straight The protrusion 632 is linearly protruded to the right side of FIG. 6 by the second system, and then drives the cylinder shaft 612 of the oil to perform a protruding action. When the cylinder shaft 612 of the oil cylinder 61 is actuated, the hydraulic oil is caused to generate a buffering blocking force. This prevents the door panel 11 from rapidly colliding with the door frame 12 when it is closed. 20 reasons, when the new door hinge is to be turned from the closed position in FIG. 6 = the open position in FIG. 5, as long as ⑽η is pulled out, the door panel can be seated at the 4th, the third pivot 52, and the% For the fulcrum to expand outward, at the same time as the expansion: the linkage # 63 will swing in a direction opposite to the direction shown by the arrow in FIG. 5 due to the swing of the deflection member 55, thereby driving the cylinder shaft 612 of the hydraulic cylinder 61 from FIG. 6 The projected state of the door returns to the retracted state of FIG. 5. When the protruding piece 511 of the connecting member 51 and the positioning support piece 42 of the door panel fixing seat 4 are placed against each other, the door type chain is switched to the open position. As can be seen from the above description, the new model can use the cylinder shaft of the hydraulic cylinder 61 when the door hinge is turned from the open position to the closed position when the door hinge is turned 11 M241479 to the closed mechanism 3 and the buffer mechanism 6 is indeed used. The 612 protrudes or retracts 1 part of the hydraulic oil, so that the installed door panel 11 can slowly lean toward or away from the mi 12 'when closed. Therefore, the door hinge of the new model does have the avoiding door panel 11 quickly and directly when the door is closed. Effect of impact door frame 12.
