Abrasion-resisting ball hinge controlled on basis of slider-crank mechanism

Abstract

The invention belongs to the technical field of ball hinges, in particular to an abrasion-resisting ball hinge controlled on the basis of a slider-crank mechanism. The abrasion-resisting ball hinge comprises a first fixing block, a first hinge, a second fixing block, a first support lug, a second support lug, a second hinge, an adjusting mechanism and the like. Convenient containing of the adjusting mechanism is the function of forming of a first containing cavity in the side face of the first fixing block. Convenient containing of a rolling ball is the function of forming of a circular hole in the side face of the second fixing block, and convenient installation of the adjusting mechanism is the function of forming of a second containing cavity in the end face of the circular hole. Compared with a traditional ball hinge, adjustment of rolling balls in the first support lug and the second support lug is the function of the adjusting mechanism, the intersection face of the second hingeand the first fixing block constantly coincides with the center face of the corresponding rolling ball, and the intersection face of the first support lug and the second support lug constantly coincides with the center face of the corresponding rolling ball; the hinge can be constantly used; and accordingly the purpose of abrasion-resisting usage of the ball hinge is achieved.

Description

technical field [0001] The invention belongs to the technical field of ball hinges, in particular to a wear-resistant ball hinge based on the control of a slider crank mechanism. Background technique [0002] After the current existing ball hinges are used for a period of time, the rolling balls in the hinge will be worn out, and the worn balls will lose the purpose of hinged two hinges, and the hinge at this time will be If it loses its function, the service life of the hinge at this time will be greatly reduced. In order to avoid this situation, the traditional improvement is to carry out special heat treatment on the rolling ball, or replace the rolling ball after the ball is worn, so as to achieve recovery. The purpose of using the function of the hinge will greatly increase the cost at this time, so in order to avoid this situation, it is necessary to design a wear-resistant ball hinge based on the control of the slider crank mechanism. [0003] The present invention d...
