Inspection jig for buckle opening and closing mechanism

Abstract

The invention discloses an inspection jig for a buckle opening and closing mechanism. The inspection jig comprises a base, two same opening and closing blocks, a spring, a plug, a rotating shaft, an operation rod and a guiding sleeve, wherein the base consists of a bottom plate and two symmetrical and parallel reference plates fixed on the bottom plate; a guiding hole and two rotating shaft holes with the same diameter are formed at the corresponding positions of the two reference plates; the rotating shaft holes are positioned above the guiding hole; the guiding sleeve is positioned in the guiding hole; the operation rod is inserted into the guiding sleeve, is in sliding connection with the guiding sleeve and consists of a thick rod and a thin rod; a circular truncated cone is arranged at the connection position between the thick rod and the thin rod; a rotating shaft insertion hole and a spring hole are formed in the opening and closing blocks; the rotating shaft is positioned in the rotating shaft insertion hole and the rotating shaft hole; the two opening and closing blocks are connected with the base through the rotating shaft respectively; the spring is positioned in the spring hole and is positioned between the two opening and closing blocks; and the plug is clamped in the spring hole. The inspection jig is easy to operate, is flexibly moved at a high speed, can be completely opened and is convenient to take.

Description

Technical field [0001] The invention relates to an inspection jig. Background technique [0002] In the process of making inspection tools for automobile decoration parts, plastic clips or metal hook mechanisms are often encountered. The function of these parts is to connect automobile decoration parts to the car body. Pull out, have a self-locking effect. But for the inspection fixture, it must be easy to click in and easy to take out. Some inspection fixture structures currently used in this technical field have great defects, such as: threaded top piece structure, which uses threaded screw to force the clamp out, which easily breaks the plastic clamp, and the metal hook cannot be used and cannot be ejected; Screw single opening and closing mechanism, which uses a vise-like action principle. The movable block is pushed open or closed by the screw rotation. This operation is slow and can only achieve unilateral opening and closing. When there are multiple clips, pick up It's ...

But for the inspection fixture, it must be easy to snap in and easy to take out

Some inspection fixture structures used in this technical field now have great defects, such as: the threaded top piece structure, which uses threaded screwing to forcibly eject the clip, which is easy to damage the plastic clip, and the metal clip cannot be used and cannot be ejected; Screw single opening and closing mechanism, which adopts the action principle similar to a vise, and uses the screw to rotate to push or pull the movable block. This operation is slow and can only achieve unilateral opening and closing. When there are multiple clips, take out not very convenient
