[0033] Reference Figure 1 、 Figure 2 and Figure 6The buffer hinge according to the first embodiment of the present invention includes a first base 100, a second base 200, a self-resetting buffer assembly 300 and a rotating member 400. The rotating member 400 includes a first rotating shaft 410, a first rotating arm 420 and a second rotating arm 430. The first rotating shaft 410 is rotatably connected to the first base 100, the first rotating arm 420 is connected to the first rotating shaft 410 and the second base 200, and the second rotating arm 430 is connected to the first rotating shaft 410 or the first rotating arm 420 and the self-resetting buffer assembly 300. One end of the self-resetting buffer assembly 300 is rotatably connected to the first base 100, and the other end is rotatably connected to the second rotating arm 430. When the rotating member 400 rotates, the self-resetting buffer assembly 300 can cooperate with the first rotating arm 420 for buffering. The first base 100 and the second base 200 rotate with each other through the rotating member 400. When the rotating member 400 rotates, the second rotating arm 430 can rotate around the first rotating shaft 410, and at the same time cooperate with the self-resetting buffer assembly 300. The self-resetting buffer assembly 300 can buffer the movement of the second rotating arm 430 relative to the first base 100. The second rotating arm 430 can increase the force arm, thereby increasing the force of the self-resetting buffer assembly 300, and the buffering effect is good. In addition, the self-resetting buffer assembly 300 only needs to be installed between the first base 100 and the second rotating arm 430, with a simple structure and convenient maintenance.

[0034] Specifically, the first base 100 can be connected to the door body, the second base 200 can be connected to the door frame, and the rotating member 400 can be rotatably connected to the first base 100 through the first rotating shaft 410. When opening and closing the door body, the first rotating arm 420 and the second rotating arm 430 both rotate around the first rotating shaft 410. When closing the door, the self-resetting buffer assembly 300 can be driven to compress when the second rotating arm 430 swings. The self-resetting buffer assembly 300 can swing while compressing, which does not affect the rotation of the door body and can achieve buffering. The structure is simple and does not require complex structures such as guide rails. The second rotating arm 430 can increase the force arm from the first rotating shaft 410. It can be understood that the self-resetting buffer assembly 300 is rotatably connected to the outer end of the second rotating arm 430, thereby increasing the buffering effect. The self-resetting buffer assembly 300 can also be easily disassembled. The self-resetting buffer assembly 300 can be removed by simply disassembling the rotating connection structure at the second rotating arm 430 and the first base 100, which is also convenient for user maintenance.

One end of the tensile elastic member 310 is pivotally connected to the first base 100, and the other end is pivotally connected to the second rotating arm 430. One end of the damper 320 is pivotally connected to the first base 100, and the other end is pivotally connected to the second rotating arm 430. The cooperation between the tensile elastic member 310 and the damper 320 can achieve the effect of automatic buffered closing of the hinge.

[0036] Specifically, the first base 100 and the second base 200 can have a closed state and an open state. In the open state, the second rotating arm 430 can drive the tensile elastic member 310 to stretch, so that the elastic force of the tensile elastic member 310 can drive the second rotating arm 430 to close in the closing direction. When closing, the second rotating arm 430 can cooperate with the damper 320 for buffering, thereby achieving the effect of automatic buffering of door closing, and the damper 320 does not need to be set as an oil pressure structure, the structure is simple, and easy to maintain.

[0037] Reference Figure 2 and Figure 5 In some embodiments of the present invention, the second rotating arm 430 has a plurality of spaced connection slots 431 for positioning and connecting the tensile elastic member 310 and the damper 320.

Firstly, the connecting groove 431 can facilitate the positioning and installation of the tensile elastic member 310 and the damper 320. Secondly, the connecting groove 431 can limit the axial sliding of the tensile elastic member 310 and the damper 320 along the second rotating arm 430, so that the self-resetting buffer assembly 300 can work normally.

[0039] Reference Figure 2 and Figure 5 In some embodiments of the present invention, the second rotating arm 430 includes a second rotating shaft 432 and a plurality of arm bodies 433. The arm bodies 433 are spaced apart from the first rotating arm 420. The second rotating shaft 432 passes through each arm body 433. Connecting grooves 431 are defined between adjacent arm bodies 433 and the second rotating shaft 432. The connecting grooves 431 where the arm bodies 433 and the second rotating shaft 432 meet facilitate assembly of the tensile elastic member 310 and the damper 320.

[0040] Specifically, the second rotating arm 430 can be connected to the first rotating arm 420, the arm bodies 433 are arranged at intervals, the arm bodies 433 can limit the axial movement of the tensile elastic member 310 and the damper 320 along the second rotating arm 430, the second rotating shaft 432 penetrates the plurality of arm bodies 433, and the second rotating shaft 432 can be connected to the tensile elastic member 310 and the damper 320 for rotation, through the above structure, the tensile elastic member 310 and the damper 320 can be conveniently assembled.

[0041] It can be understood that the plurality of arm bodies 433 can be cut and formed at intervals to form the second rotating arm 430, and the processing process is relatively simple.

Thus, the front and back directions of the hinge can be adjusted through the adjusting hole 223.

[0043] Specifically, the sliding groove 221 can be arranged in extension through the side of the adjusting seat 220, the adjusting seat 220 is provided with the adjusting hole 223 extending in the front and back directions as a waist-shaped hole, the connecting seat 210 is connected with the adjusting seat 220 by a bolt, the adjusting seat 220 can be adjusted in direction along the front and back directions, and when the first connecting hole 211 and the adjusting hole 223 are kept corresponding, the front and back directions are adjusted, the threaded block 222 in the sliding groove 221 can be screwed with the first connecting hole 211 and the adjusting hole 223 by the bolt, the threaded block 222 is provided with a threaded hole, and the threaded block 222 can be slid to keep the threaded hole corresponding to the first connecting hole 211 and the adjusting hole 223 for screwing by the bolt. Through the above structure, the front and back positions of the hinge can be adjusted to adjust the position of the door body.

[0044] It should be noted that the first rotating arm 420 and the second rotating arm 430 are of an integrated structure. Specifically, the first rotating arm 420 and the second rotating arm 430 can be integrally cast or integrally machined, which is simple in structure and can reduce the processing cost.

[0045] Referring to Figures 3 to 5In some embodiments of the present invention, the first rotating arm 420 includes a first arm segment 421 and a second arm segment 422, which are perpendicular to each other.

The second rotating arm 430 is connected to the first arm segment 421, and the second rotating arm 430 extends away from the second arm segment 422. The second rotating arm 430 is perpendicular to the first arm segment 421. Specifically, the first arm segment 421 and the second arm segment 422 can be arranged approximately perpendicularly, which can provide an avoidance space when the door is opened and closed, allowing the door to maximize the opening and closing angle. The second rotating arm 430 can be provided on the first arm segment 421 and arranged perpendicularly thereto, so that the second rotating arm 430 can utilize the moment arm of the first arm segment 421 to extend the moment arm length in a limited space and enhance the buffering effect.

[0046] Reference Figures 2 to 4 In some embodiments of the present invention, the first base 100 includes a base body 110 and a bottom box 120. The bottom box 120 is detachably connected to the base body 110, and the bottom box 120 is provided with a receiving groove 121. The tensile elastic member 310 and the damper 320 are installed in the receiving groove 121.
