The invention provides a self-locking switch, which cooperates with the lock hole, and includes: a key, a first rotating shaft, a second rotating shaft, a sleeve and an elastic member, and the key, the first rotating shaft and the second rotating shaft are all movably inserted in the sleeve Inside, the elastic part is set in the sleeve and pushes up the second rotating shaft, and the two ends of the sleeve are respectively equipped with anti-loosening parts and anti-loosening flanges for preventing internal parts from slipping out; the first rotating shaft is a hollow shaft, and the second The upper end of the rotating shaft is inserted in the first rotating shaft, the lower end of the key is inserted in the first rotating shaft and touches the upper end of the second rotating shaft; The upper end is provided with a second locking tooth and the fourth locking tooth; the lower end of the second rotating shaft is provided with a locking part. The self-locking switch is simple and convenient to operate. The present invention also provides a light box, including a box body, a cover body and the above-mentioned self-locking switch. Corresponding to the lock hole, the lock part is locked in the lock hole.
Description
technical field [0001] The invention belongs to the technical field of switches, in particular to a self-locking switch and a light box using the switch. Background technique [0002] A switch mechanism is usually arranged between the box body and the cover body of the light box to fix and close the two. There are mainly two types of switch mechanisms in the prior art: snap mechanism and bolt mechanism. The buckle mechanism refers to a mechanism that fixes and closes in a buckle manner by setting fasteners and buckle holes on the box body and the cover body respectively. The bolt mechanism refers to a mechanism that fixes and closes the box body and the cover body by means of bolt fastening. Among them, the buckle mechanism has a short service life and is inconvenient to operate; the bolt mechanism is inconvenient to operate and has low opening / closing efficiency, especially not suitable for light boxes installed at high altitudes. The operation of loading and unloading bo...
