Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of intelligent locks, specifically a kind of buckle type intelligent lock. BACKGROUND

[0002] In recent years, with the improvement of Internet of Things technology and user safety needs, the intelligent door lock market is booming. Compared with traditional mechanical locks, intelligent locks integrate electronic control modules, batteries and complex transmission mechanisms.

[0003] The market commonly used zinc alloy die casting, stainless steel, engineering plastics and aluminum alloy for the shell of intelligent lock, among which aluminum alloy becomes one of the ideal materials for the shell of intelligent lock due to its lightweight, good heat dissipation, excellent metal texture, easy surface treatment, good workability and moderate cost, especially favored by those who pursue texture and lightweight products. Among them, the "pull aluminum" process can efficiently produce profile with complex cross-sectional shape, accurate size and smooth surface, which is very suitable for manufacturing intelligent lock side frame or panel body with specific profile.

[0004] Although aluminum alloy has obvious advantages in the application of intelligent lock shell, its inherent material properties, lower hardness than stainless steel, etc. lead to problems of fixing reliability. Currently, the industry generally uses screw fastening to connect and fix different parts of the shell, such as using a stainless steel bottom plate and a top plate, and using an aluminum alloy side frame. The aluminum alloy is relatively soft, and the threads are prone to wear, deformation or even thread slipping when the screw is screwed in or repeatedly disassembled, which causes the connection point to loosen, directly affecting the structural rigidity and integrity of the lock body. This looseness not only may produce abnormal noise, but more importantly, it reduces the resistance of the lock body to external impact, which poses a safety hazard. At the same time, the screw head is exposed on the surface of the shell, which may affect the overall integrity and simple beauty of the product appearance. SUMMARY
