AI Technical Summary
Existing hinges are prone to producing impact noises during the opening and closing of hardware boxes, which can damage the box lid and shorten its service life.
Design a damping hinge with buffer closing function. By setting a cam pressure block, upper connecting part, lower connecting part and sliding fixing part, combined with a buffer, the hinge can be slowly closed after being flipped to a 90-degree angle, reducing impact noise and connection gap.
It effectively avoids impact noise and gaps when the lid closes, extending the service life of the hinges.

[0013] The technical solutions in the embodiments of the utility model will be apparently and completely described in connection with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.
[0014] Secondly, "one embodiment" or "embodiment" referred to here means that specific features, structures or characteristics can be included in at least one implementation of the utility model. "In one embodiment" appearing in different places in the specification does not mean the same embodiment, nor is it an embodiment that is independent or alternative to other embodiments. EMBODIMENT
[0015] Please refer to Figures 1-2 As shown in the figure, the utility model provides a kind of damping hinge with buffer closing function, including cam pressing block 1, the lower end of cam pressing block 1 is fixedly installed with upper connecting part 2, the lower end of upper connecting part 2 is rotatably installed with lower connecting part 4 by hinge pin 3, the outside of the lower end of lower connecting part 4 is fixedly installed with sliding fixing piece 5, the inside of sliding fixing piece 5 is insertedly installed with buffer 6, and the lower end of buffer 6 is set in protruding.
[0016] The application of upper connecting part 2, lower connecting part 4, sliding fixing piece 5 and buffer 6 is arranged in the technical scheme, in the process of using the hinge to turn, it can be opened to ninety degrees, the buffer 6 is installed in it, the hinge damper pressing block is rotated to compress the buffer 6 to generate buffer force, so that the hinge is slowly closed, and when covering, it has the function of buffer closing, can avoid the gap at the connecting part after the used box cover is closed, further prevent the large impact sound when the box cover is closed. EMBODIMENT
[0017] On the basis of embodiment one, the utility model discloses as shown in Figure 2 The surface of upper connecting part 2 and lower connecting part 4 is provided with mounting hole, and mounting hole is installed symmetrically up and down;The two sides of the upper end of lower connecting part 4 are fixedly installed with the connecting sleeve for installing hinge pin 3, and the upper end of the other connecting sleeve is clamped to the inside of the lower end of upper connecting part 2.
[0018] It adopts as Figure 1The mounting hole of the connecting part surface can be connected with the surface of the box body, and the hinge can be quickly installed on one side of the box body as a whole; the buffer 6 and the sliding fixing part 5 are connected with each other, so that the hinge can reduce impact after being closed, has the function of buffer closing, and can protect the used box body.
[0019] The working principle of the utility model is that through the setting of the upper connecting part 2, the lower connecting part 4 and the sliding fixing part 5, the hinge can be opened to an angle of ninety degrees in the process of being used to turn over, and has the function of buffer closing when being closed, so that the gap at the connecting part after the closing of the used box cover can be avoided, and further, the loud impact sound caused by the closing of the box cover can be prevented.
