The lower end of the upper hook is inserted into the lock groove, and after the lower end of the upper hook is fully inserted, it is inserted into the upper end of the lower hook, thus locking the two components together.
[0008] Furthermore, the locking process of the locking device of this utility model is as follows: when the lower end of the upper hook is inserted into the locking groove, the front side of the upper end of the lower hook is subjected to force to press the spring backward, the spring contracts, and the lower hook slides backward parallel to the bottom of the locking groove. After the lower end of the upper hook is fully inserted, it engages with the upper end of the lower hook, thus completing the final locking of the locking device of this utility model.
[0009] Furthermore, the opening process of the locking device of this utility model is as follows: When it is necessary to open the locking device, press the front end of the lower hook inward, the spring contracts, the lower hook slides backward parallel to the bottom of the locking groove, the lower end of the upper hook separates from the upper end of the lower hook, and the upper hook is pulled out to unlock.
[0010] The advantages of this utility model are as follows: Compared with the prior art, the locking device of this utility model can achieve automatic insertion. Simply insert the lower end of the upper hook into the locking groove, and the upper and lower hooks will lock together, making it very convenient to use. It can be installed on the surface or inside of an object. For example, it can be installed on the body and lid of a turnover box to lock the turnover box.
