The third hole 36c of the side wall 26b and the first through hole 46a of the first support ear 42a are used to connect the hinge arm 14 and the first elastic member 18, so that the first elastic member 18 provides a first elastic force against the first elastic member 18. Articulated arm 14.

The second tip 24 is U-shaped, and its two ends are passed through the fourth hole 36d and the fifth hole 36e of the second side wall 26b of the head seat 10, and the second end of the second support ear 42b. The second elastic member 20 is connected to the through hole 46 b so that the second elastic member 20 provides a second elastic force against the hinge arm 14 .

As shown in Figure 4, the mounting part 12 of the hinge is installed on a cabinet body 76, and the head seat 10 is installed on a door panel 78, and when the door panel 78 is displaced to a closed position relative to the cabinet body 76, as shown in Figure 5 and As shown in FIG. 6, the hinge arm 14 will collide with the slider 50, so that the slider 50 moves backward and the piston rod 56 is slowly retracted into the buffer member 48 to produce a buffer effect, that is, the door panel 78 The closing relative to the cabinet body 76 can be performed slowly and quietly. At the same time, the pair of wings 60 of the slider 50 will leave the first support ear 42a and the second support ear 42b of the headstock 10 (as shown in FIG. 6 , one wing 60 leaves the first support ear 42a), and the The concave portion 58 of the slider 50 is disengaged from the blocking portion 38 of the header 10 .

As shown in FIG. 7 , when the hinge arm 14 is unfolded relative to the headstock 10, the piston rod 56 of the buffer member 48 stretches out to drive the displacement of the slider 50 until the pair of wings 60 of the slider 50 abut against The first support ear 42a and the second support ear 42b of the headstock 10 stop (the figure reveals that a wing 60 abuts against the first support ear 42a), and at this time, the recess 58 of the slider 50 is also in contact with the headstock. The blocking portion 38 of 10 is in contact with each other, so that the slider 50 stops at a position that can be pushed against and has a buffering effect relative to the hinge arm 14 .

As mentioned above, the positioning method of the buffer device 16 in the embodiment of the present invention installed on the headstock 10 is mainly through the fitting part 54 of the buffer member 48 passing through the opening 64 of the fixing cover 52 and the headstock 10. The hole wall of the positioning hole 40 of the rear end wall 32 of the rear end wall 32 is positioned against the hole wall, and at least one hook portion 68 of the fixed cover 52 and the buckle portion 44 of the bottom wall 28 of the head seat 10 are locked and positioned mutually, so that the buffer device 16 can be stably installed on the headstock 10, and when the slider 50 collides against the hinge arm 14 and is in a buffer displacement process, the pair of wings 60 of the slider 50 can be placed on the fixed cover 52 The linear sliding in the pair of slide grooves 70 provides a smooth and stable cushioning force. Therefore, the present invention can ensure that the buffer device 16 can provide a stable buffer displacement stroke when the slider 50 is bumped by the hinge arm 14 , that is, when the hinge arm 14 is closing relative to the headstock 10 .

It should be noted that the buffer displacement stroke of the above-mentioned buffer device 16 can be planned to be adjustable, as shown in Figure 8 and Figure 9, in a further embodiment, the head seat 10 of the hinge has a guide groove 80 located The bottom wall 28 of the header 10 and the guide groove 80 are substantially perpendicular to the rear end wall 32 of the header 10 . The fixed cover 52 of the buffer device 16 has an opening 82 communicating with the receiving groove 62 ; the buffer member 48 further includes a threaded portion 84 , a guiding portion 86 , and an adjusting member 88 . Wherein, the threaded portion 84 is corresponding to the positioning hole 40 of the rear end wall 32 of the header 10 , so that a part of the threaded portion 84 of the buffer member 48 can pass through the positioning hole 40 . The guiding portion 86 is a part of the guiding groove 80 passing through the bottom wall 28 of the header 10 , so that the buffer member 48 can move linearly relative to the header 10 . The adjusting member 88 is placed in the opening 82 of the fixing cover 52 and movably screwed to the threaded portion 84 of the buffer member 48 , and a part of the adjusting member 88 is exposed at the opening 82 of the fixing cover 52 . Thereby, the aforementioned buffer element 48 can move linearly through the slot 62 of the fixed cover 52 .

Furthermore, when the adjusting member 88 is rotated, the buffer member 48 responds to the rotation of the adjusting member 88 and is displaced to a first position relative to the headstock 10, as shown in FIG. 10 , the sliding of the buffer member 48 The relative position of the block 50 relative to the hinge arm 14 can also be changed, and then used to adjust the contact angle at which the hinge arm 14 folds relative to the headstock 10 and starts to abut the slider 50 to produce a buffering effect, that is, as shown in FIG. It is disclosed that when the door panel 78 is at a closing angle α relative to the cabinet body 76 , the buffering effect is activated, so that the door panel 78 can move slowly and quietly relative to the cabinet body 76 within such an angle range of α. Similarly, when the adjusting member 88 is rotated again and the buffer member 48 is displaced to a second position relative to the headstock 10, as shown in FIG. During the buffering effect, its contact angle can be adjusted from the original α angle to a β angle. Therefore, when the door panel 78 is closed and displaced to the β angle relative to the cabinet body 76, the buffering effect will be started immediately, so that the door panel 78 will be relative to the cabinet body 76. The cabinet body 76 can move slowly and quietly in such a range of β angles.

In addition, when the above-mentioned hinge has the buffer device 16 but does not use its buffer function, as shown in FIG. , make the slider 50 far away from the hinge arm 14, so that when the hinge arm 14 is completely closed relative to the headstock 10, the hinge arm 14 will not touch the slider 50, so that the user can provide a closed Mechanism of buffering.

According to the above description, it can be seen that the enhanced function and advantage of the present invention is that: the buffer device is stably installed on the hinge. On the other hand, the buffer displacement stroke can be adjusted.

Although the present invention has been described with reference to the current specific embodiments, those of ordinary skill in the art should recognize that the above embodiments are only used to illustrate the present invention, and other modifications can be made without departing from the spirit of the present invention. Various equivalent changes and modifications, therefore, as long as the changes and modifications to the above embodiments are within the true spirit of the present invention, they will all fall within the scope of the claims of the present application.
