Detailed Description

The hinge structure with a position limiting function of the present invention will be further described with reference to the following embodiments to help those skilled in the art to more fully, accurately and deeply understand the technical solution of the present invention.

Example 1

As shown in fig. 1-2, the hinge structure with a stopper function of the present embodiment includes an upper hinge arm 10, a lower hinge arm 20, and a hinge pin 30. The upper hinge arm 10 comprises an upper hinge arm body 11, an upper connecting plate 12 is arranged on one side of the upper hinge arm body 11, and a first bolt mounting hole 15 is formed in the upper connecting plate 12. The upper hinge arm body 11 is provided with a hinge shaft upper hole 13 penetrating through the upper surface and the lower surface, and the side wall of the upper hinge arm body 11 is provided with a limiting mounting hole 14 communicated to the hinge shaft upper hole 13. The lower hinge arm 20 comprises a lower hinge arm body 21, a lower connecting plate 22 is arranged on one side of the lower hinge arm body 21, and a second bolt mounting hole 25 is formed in the lower connecting plate 22. The lower hinge arm body 21 is provided with a lower hinge shaft hole 23 penetrating the upper and lower surfaces, and the sidewall of the lower hinge arm body 21 is provided with a hinge pin mounting hole (not shown) communicating with the lower hinge shaft hole 23. The hinge shaft 30 includes a hinge shaft seat 31, and the hinge shaft seat 31 is a cylindrical structure. The lower part of the hinge shaft seat 31 is provided with a hinge lower shaft 32, the upper part of the hinge shaft seat 31 is provided with a hinge upper shaft 33, and the outer wall of the hinge upper shaft 33 is provided with a limit groove. The upper and lower surfaces of the hole 13 on the hinge shaft are provided with bushings 40, and the installation of the bushings 40 can play a role of preventing abrasion. The hinge lower shaft 32 is fitted into the hinge shaft lower hole 23 and fixed by a hinge pin 60 fitted in the hinge pin fitting hole, and the hinge shaft seat 31 is located between the upper hinge arm body 11 and the lower hinge arm body 21. The upper hinge shaft 33 is disposed in the upper hinge shaft hole 13 and is pressed against the hinge shaft by a washer 50 disposed at the upper end of the hinge pin 30, preventing the hinge shaft from falling off. And a limiting structure matched with the limiting groove is arranged in the limiting mounting hole 14. The limiting structure comprises a steel ball 70 matched with the limiting groove, and the steel ball 70 is installed in the limiting installation hole 14 through a compression spring 80 and a hollow bolt 90.
