Description

Technical Field

[0001] The utility model relates to a buckle lock, in particular to a motor buckle lock with a fixed buckle anti-rebound structure. Background Art

[0002] A hasp lock is a lock that rotates and locks the bolt by impact. It is widely used in cabinet door technology in industries such as container cabinets, telecommunications, energy storage, and automated control manufacturing. It allows the lock to engage or disengage the bolt with the door frame. Some hasp locks are equipped with motors and solenoid valves, which function as energy storage. The market for energy storage hasp locks is promising, especially in the field of new energy storage locks. Due to the rapid development of the new energy storage lock market, new installations are expected to create a huge market demand for energy storage hasp locks. Their use in new energy storage equipment not only improves installation efficiency but also ensures consistent assembly quality. For example, the application number 201420392944.3 disclosed in the Chinese patent document, the authorization announcement date 2014.12.03, and the utility model name "electromechanical dual-purpose hidden buckle"; another example is the application number 20182213222.06 disclosed in the Chinese patent document, the authorization announcement date 2019.12.06, and the utility model name "electromagnetic buckle lock"; but some existing conventional motor buckle locks mainly use the scheme of pulling the lock open by rotating the motor. The unlocking torque of this type of buckle lock is large, and the fixed buckle is difficult to be stuck in the original position, and the torsion spring force is difficult to automatically bring it back to the original position; other similar motor buckle locks also mainly use the scheme of pulling the lock open by rotating the motor, but after pulling it open, the limit part falls by its own gravity to limit the rebound of the fixed buckle. Its stability and safety are poor, and it is easy to be forced to open. Summary of the Invention

[0003] The purpose of this utility model is to provide a motor-operated buckle lock with a retaining buckle anti-rebound structure, addressing the technical problems of existing similar products, such as large unlocking torque, difficulty in retaining the retaining buckle in its original position, and difficulty in automatically returning the retaining buckle to its original position due to the torsion spring force. This purpose is achieved through the following technical solution.

[0004] The locking mechanism of the locking cam is actuated by a spring which engages with the locking cam to engage with the first notch of the locking cam and engages with the second notch of the locking cam to engage with the second notch of the locking cam. Therefore, after the motor buckle lock is unlocked, the lock tongue and the lock hook need to be re-engaged, and the limit slider column must be unlocked first before the fixed buckle can be reset to the locked state; at the same time, after the motor buckle is unlocked, the slider spring pushes the limit slider column to clamp the fixed buckle, and after the motor rotates, the fixed buckle is clamped by the limit slider column; the anti-slip structure between the above-mentioned fixed buckle and the lock tongue is more stable.

[0005] The other end of the fixing buckle extends out of the housing and is connected to one end of the steel wire. One end of the steel wire sleeve at the outer diameter of the steel wire end is fixed to the outer diameter of the housing via a mechanical unlocking lock seat. The other end of the steel wire is connected to the mechanical unlocking lock tongue of the mechanical lock. The other end of the steel wire sleeve at the outer diameter of the steel wire end is fixed to the mechanical lock core fixing bracket. Therefore, by pulling the fixing buckle by the steel wire, the second notch of the fixing buckle can be disengaged from the limit slider column. At the same time, the first notch of the fixing buckle can be disengaged from the lock hook. At this time, the lock tongue can also be pulled to drive the lock hook to rotate and disengage.

[0006] The driving element is a motor, whose motor shaft is connected to the motor shaft. The pin of the motor shaft is inserted into a rotation hole at one end of the rotary lock sleeve, and the other end of the rotary lock sleeve abuts against the raised portion of the fixing buckle. The driving element may also be a solenoid valve, whose movable iron core extends outward and abuts against the raised portion of the fixing buckle. The motor or solenoid valve is connected to the PCB mainboard within the housing via wiring. Both the above motor and solenoid valve structures can achieve position limiting and actuation of the fixing buckle, but the motor structure achieves a better effect by preventing the fixing buckle from rebounding after the unlocking motor rotates.

[0007] The slider spring is arranged in a spring groove on one side of the limiting slider column, and one end of the slider spring extending out of the limiting slider column abuts against the rib column in the housing.

[0008] The locking hook is F-shaped, with the U-shaped opening hingedly fixed below the housing for swinging. The hook's end at one end of the retaining clip has an arcuate edge. This arcuate edge and the second notch in the arcuate opening of the retaining clip are located outside the circumference of the limiting slider column. This structural design minimizes space occupied within the housing while enabling the aforementioned linkage and interlocking.

[0009] The lock is T-shaped, with a magnet on one side of the lock, and the lock is adsorbed on the outer diameter side of the shell through the magnet. The lock can also adopt other lock methods, such as a lock with a bent wire fixed to the lock plate.

[0010] A connecting piece is provided between the hinge points of the outer diameter of the housing or the fixing buckle and the locking buckle in the housing to connect the hinged swing positions. The above further improves the firmness of the two hinge points of the fixing buckle and the locking buckle.

[0011] Micro switches are provided at corresponding positions of the driving member, the fixing buckle, the locking buckle and / or the limit slider column in the housing, so as to facilitate detection of the state of the lock tongue through the micro switches.

[0012] The utility model has a reasonable structural design, is easy to use and assemble, has good safety and stability, and has two forms of mechanical unlocking and motor unlocking; it is suitable for use as a motor buckle lock with a fixed buckle anti-rebound structure, and is a structural improvement of similar products.
