Embodiment Construction

[0016] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0017] like Figure 1-2 As shown, a tamper-proof manual latch mechanism includes a positioning pin 1 , a base 2 is provided at the lower part of the positioning pin 1 , and the positioning pin 1 passes through the base 2 .

[0018] Both sides of the base 2 are respectively provided with bushings 4 corresponding to the positioning pins. A plunger hole 10 is installed on the base 2 , and an annular groove 8 corresponding to the plunger hole 10 is provided on the positioning pin 1 . There is an internal thread in the plunger hole 10, and the plunger hole is connected with a ball plunger 5 through the internal thread, and the inner end of the ball plunger 5 corresponds ...

Abstract

The invention discloses an anti-shifting manual bolt mechanism which comprises a positioning pin, wherein a base is arranged on the lower portion of the positioning pin, and the positioning pin penetrates through the base. bushings corresponding to the positioning pin are arranged on the two sides of the base respectively; a plunger hole is formed in the base, and an annular groove corresponding to the plunger hole is formed in the positioning pin; internal threads are arranged in the plunger hole which is connected to a ball plunger through the internal threads, and the end part of the inner side of the ball plunger corresponds to the annular groove. Manual positioning of the positioning pin is achieved through the base, the ball plunger and an anti-rotating pin, so that the structure is simple, operation is easy, the positioning requirements can be met, the positioning pin can be effectively prevented from moving front and back, and good stability is achieved.

Description

technical field [0001] The invention relates to the field of mechanical equipment for processing body parts, in particular to a movement-proof manual latch mechanism which is convenient for positioning during assembly and welding. Background technique [0002] In the assembly and welding production process of the automobile body, especially in the assembly process of the adjustment wire harness, due to the needs of specific occasions, the positioning mechanism needs to use telescopic pins for positioning. [0003] Generally, when telescopic pins are used, double guide rod telescopic cylinders are usually used. In this way, the staff needs to design the gas path, limit mechanism, control valve plate and so on. When a manual latch is required, a handle needs to be designed, because the mechanism will be complicated and cumbersome, difficult to operate, increase maintenance costs, and increase the failure rate of equipment. [0004] A simple manual latch solution commonly use...
