The invention relates to a lock catch device. The lock catch device comprises a shell, an opening, a clamping cover, an elastic metal wire and a lock catch, wherein the shell is provided with a cavity; the opening is formed in the top of the shell and communicated with the cavity; the clamping cover is arranged on the top of the shell and covered on the opening of the shell; the top of the first end of the clamping cover is provided with an accommodating groove; the second end, opposite to the first end, of the clamping cover is pivoted to the first end of the top of the shell; the elastic metal wire is accommodated in the accommodating groove of the clamping cover, and the lock catch is connected to the first end of the clamping cover in a sliding mode; the lock catch is provided with a clamping hook for catching the second end opposite to the first end on the top of the shell; when the lock catch slides back the second end of the clamping groove, the elastic metal wire is compressed, and the clamping hook is separated from the second end of the top of the shell; the elastic metal wire is formed by bending a metal wire back and forth in the same plane; and the elastic metal wire is flatly placed in the accommodating groove of the clamping cover. The elastic metal wire is skillfully used in the device; and the device has the advantages of simple shape, small volume and reliable elasticity.
Description
technical field [0001] The invention relates to a locking device, in particular to a locking device for a battery door or an SD card cover of an electronic product. Background technique [0002] The lock of the battery door and SD card cover is a common structure of mobile phones and digital products. In order to ensure that it can be locked, it often needs the assistance of elastic bodies, and the elastic bodies also play the role of timely reset after unlocking. [0003] Commonly used elastic bodies are springs, torsion springs, or rely on the elasticity of the plastic parts themselves. However, springs and torsion springs often take up a relatively large space and are not easy to fix; plastic elastic structures have unreliable elasticity and are easily damaged. Contents of the invention [0004] The invention provides a locking device to solve the problems in the prior art that the springs and torsion springs occupy a large space and the elastic force of the plastic el...
