CN202269542U - Limit structure for spectacles case - Google Patents

Abstract

The utility model relates to a limit structure for a spectacles case, which is characterized in that a locking rib is arranged on a left lower guard plate of an instrument panel; a locking claw is arranged on a spectacles case body; and a strengthening rib is arranged at the root of the locking claw. The limit structure for a spectacles case is reasonable and simple in structure and can effectively prevent interference failure of the locking claw and a locking point of the lower guard plate caused by deformation of the case body.

Description

The spectacle case position limiting structure

Technical field

The utility model relates to a kind of spectacle case position limiting structure, belongs to the technical field of instrument panel structure design.

Background technology

Spectacle case is a plastic material, non-elastic material, and in the opening and closing process, locked point produces distortion owing to be squeezed, and the long-term back locking power of using descends.Behind the height of deflection greater than locked point, can cause automatic unlatching, influence the function of part; Glasses box body centre structure is the weakest, is easy to produce arc-shaped deformation.

Summary of the invention

The utility model purpose is to provide a kind of spectacle case position limiting structure, and it is simple and reasonable for structure, can prevent effectively to cause losing efficacy with the locked point interference of following backplate because of the box body distortion.

The technical scheme of the utility model is achieved in that the spectacle case position limiting structure, it is characterized in that: backplate is provided with the locking muscle under an instrument board left side; The locking claw is set on the glasses box body, and designs reinforcement at the root of locking claw.

The good effect of the utility model is the root design reinforcement of the locking claw in the deformed area, has prevented distortion effectively; The locking claw is arranged in intensity two side areas preferably, in case lost efficacy because of box body is out of shape the locked point interference that causes with following backplate.

Description of drawings

Fig. 1 is spacing for the spectacle case of the utility model, deformed region, the backplate sketch map of sitting down.

Fig. 2 is the spectacle case locking muscle position of the utility model

Fig. 3 is the sketch map of the spectacle case position limiting structure of the utility model.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is done further description: shown in Fig. 1-3, the spectacle case position limiting structure is characterized in that: backplate 5 is provided with locking muscle 1 under an instrument board left side; Locking claw 3 is set on glasses box body 2, and designs reinforcement 4 at the root of locking claw 3.

Backplate 5 is provided with locking muscle 1 (Fig. 2) under an instrument board left side; Locking claw 3 is set on glasses box body 2, and designs reinforcement 4 (Fig. 3) at the root of locking claw 3.For preventing glasses box body 2 in A and B two places distortion (Fig. 1), the root of the A place locking claw 3 design reinforcement 4 (Fig. 3) in the deformed area; For preventing that the glasses box body because of the centre structure is the weakest, is easy to produce arc-shaped deformation, locking claw 3 is arranged in intensity two side areas (Fig. 3) preferably.

Claims (1)

1. spectacle case position limiting structure, it is characterized in that: backplate is provided with the locking muscle under an instrument board left side; The locking claw is set on the glasses box body, and designs reinforcement at the root of locking claw.
