Description

Technical Field

[0001] The utility model relates to the technical field of hinges, in particular to a four-link hinge buffer mechanism. Background Art

[0002] During movement, mechanical structures often generate vibrations and shocks, which affect the mechanical system and the user. The four-link hinge buffer mechanism can reduce these adverse effects through specific design and construction, thereby improving the stability of the mechanical system and the comfort of the user. Therefore, it is necessary to design a four-link hinge buffer mechanism.

[0003] To this end, the patent with publication number CN211369938U discloses an elastic four-bar hinge mechanism, including a first base, a second base, a telescopic assembly and a limiting assembly. The first base and the second base are hingedly connected to the telescopic assembly at both ends of the side wall respectively. The telescopic assembly is slidably arranged at the two ends of the second base. The limiting assembly includes an elastic module and a limiting module. The two side walls of the limiting assembly are hingedly connected to the telescopic assembly and the second base respectively, and the elastic module is arranged in the limiting module. A tension spring is arranged between the limiting module and the elastic module. One end of the limiting module is rotatably connected to the elastic module, and the other end is clamped with the elastic module. When the gate cover is rotated to open, the telescopic assembly unfolds and drives the limiting module to slide relative to the elastic module. At this time, the tension spring becomes longer and accumulates elastic force. When the gate cover slides to be fully opened, the tension spring naturally recovers to drive the limiting module to clamp with the elastic module, thereby realizing the self-locking effect of the hinge mechanism.

[0004] Although the elastic four-link hinge mechanism mentioned above can achieve the effect of hinge self-locking, the connection will be worn after the gate cover is opened and closed many times during use, which will damage the hinge body. Therefore, it is necessary to design a four-link hinge buffer mechanism that can protect the hinge. Utility Model Content

[0005] The utility model aims to provide a four-link hinge buffer mechanism to solve the defect that the connection of the existing elastic four-link hinge mechanism will be worn after the gate cover is opened and closed many times, thus damaging the hinge body.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a four-link hinge buffer mechanism, comprising a top plate and a side plate;

[0016] The four-link hinge buffer mechanism provided by the utility model has the following advantages:

[0017] By providing a protective structure, when the four-bar hinge body is used, the top end of the four-bar hinge body and the bottom end of the top plate may damage the four-bar hinge body due to mutual friction after long-term use. By fixing a protective sticker on the top end of the four-bar hinge body and fixing a protective pad on the bottom end of the top plate, the direct contact between the four-bar hinge body and the top plate can be reduced, and the loss and wear can be reduced.

When the four-bar hinge body needs to be closed, the buffer spring slowly contracts inwards, and the elasticity gradually decreases, playing a buffering role, so that the device has a buffering function, and the safety and service life of the four-bar hinge buffer mechanism when in use are improved;

[0019] By providing a mounting structure, the four-bar hinge body and another object can be connected to each other through the mounting plate and the fixing bolt, which is convenient for installation. When the mounting plate and other objects are installed, the anti-skid pad can play a good anti-skid role, thereby realizing the function of easy installation of the device and improving the convenience of the four-bar hinge buffer mechanism when in use.

[0029] When the four-bar hinge body 4 is used to open and close, the buffer spring 502 will add a certain resistance to the movable plate on the top of the four-bar hinge body 4 to prevent the four-bar hinge body 4 from damaging surrounding parts due to excessive movement during use. When the four-bar hinge body 4 needs to be closed, the buffer spring 502 slowly contracts inward, and the elasticity gradually decreases, thereby playing a buffering role.
