Description

Technical Field

[0001] The utility model relates to a hasp lock, which is a multi-detection trigger type electronic hasp lock. Background Art

[0002] A hasp lock, a type of lock that locks by rotating a connecting rod through impact, is widely used on metal cabinet doors in industries such as telecommunications, power generation, and automated control manufacturing. However, conventional industrial electronic hasp locks require opening the back door for emergency unlocking in the event of a power outage, making them inconvenient to use. Some hasp locks feature an electromagnet assembly, such as the one disclosed in Chinese patent application number 201822132220.6, published on December 6, 2019, under the utility model designation "Electromagnetic Hasp Lock." The movable iron core and fixed buckle of these electromagnet assemblies are primarily connected via a rod sleeve, resulting in poor stability. Some other electronic buckle locks are equipped with not only an electromagnet assembly but also a steel wire rope, such as the application number 201420392944.3 disclosed in the Chinese patent literature, the authorization announcement date 2014.12.03, and the utility model name "electromechanical dual-purpose hidden buckle"; one end of the steel wire rope in the shell is mainly limited by the positioning part to make the rocker rod in the shell offset and limit or offset each other. It mainly uses a motor rather than an electromagnet assembly. At the same time, the above-mentioned products and existing products rarely use the steel wire rope to directly connect with the fixed buckle to realize the unlocking and locking of the mechanical lock, and the emergency unlocking structure is poor. Summary of the Invention

[0003] To overcome the aforementioned shortcomings, the present invention aims to provide a multi-detection trigger-type electronic hasp lock in the art. This solves the technical problems of existing similar hasp lock products, such as the limited use of a steel wire rope directly connected to a fixed buckle to achieve mechanical lock unlocking and closing, and the inadequate emergency unlocking structure. This objective is achieved through the following technical solution.

[0004] A multi-detection trigger electronic hasp lock comprises a mechanical lock, an electronic lock, and a wire rope. The electronic lock includes an electromagnet assembly. A lock tongue is provided at an opening on one side of the base plate of the electronic lock. A U-shaped opening is provided on one side of the lock tongue, and a lock latch is provided at the opening to strike and lock into the opening. A lock latch torsion spring is provided at the rotating shaft of the lock tongue. The cover plate corresponds in shape to the base plate, and a corresponding U-shaped opening is provided on the unlocking side of the lock tongue. One end of the wire rope is connected to the fixed bracket of the mechanical lock, and the other end of the wire rope is connected to one end of the fixed buckle. The key structural design features a lock tongue groove on the inner side of the other end of the fixed buckle to limit rotation on the other side of the lock tongue opening. The lock tongue groove of the fixed buckle is fixed to the base plate for swinging. The inner center between the connection point between the fixed buckle and the wire rope and the swing point is connected to the moving iron core of the electromagnet assembly. The electromagnet assembly is connected to the PCB circuit board within the base plate via wiring. Therefore, after the electromagnet assembly is energized, the moving iron core drives the fixing buckle to rotate, so that the lock tongue groove of the fixing buckle is unlocked and disengaged from the lock tongue; or after the mechanical lock at the wire rope is unlocked, the mechanical lock rotates and drives the wire rope to pull the fixing buckle to rotate through the fixed bracket, so that the lock tongue groove of the fixing buckle is unlocked and disengaged from the lock tongue.

[0005] A raised switch post is provided on the inner side of the fixing buckle. When the locking tongue groove of the fixing buckle is unlocked and disengaged from the other side of the opening of the locking tongue, the switch post of the fixing buckle abuts against each other and triggers the lock detection switch in the base plate. The lock detection switch is connected to the PCB circuit board in the base plate via a circuit. This facilitates real-time monitoring of the working status of the lock through the lock detection switch.

[0006] The connection between the fixing buckle and the wire rope, and the connection between the fixing buckle and the moving iron core of the electromagnet assembly, both extend out of the bottom plate and the cover plate. The above is a specific method for fixing the wire rope. The wire rope includes a wire rope core box and a wire rope sleeve. The two ends of the wire rope are mainly fixed by the wire rope sleeve. The wire rope core is connected to the fixing buckle and the fixed bracket respectively to achieve a linkage effect.

[0007] At least one push rod with one end extending outward is installed on one side of the U-shaped opening of the base plate. The other end of the push rod inside the base plate is equipped with a corresponding door panel detection switch. The outer diameter of the push rod inside the base plate is equipped with a push rod spring for resetting the push rod. The panel detection switch is connected to the PCB circuit board inside the base plate via a circuit. This further allows the door panel detection switch to monitor the working status in real time.

[0008] The bottom plate is provided with a limiting column for limiting the rotation of the lock tongue and the fixing buckle, and the lock tongue and the fixing buckle corresponding to the limiting column are respectively provided with a limiting groove or a limiting edge.

[0009] One end of the steel wire rope is fixed to the adjusting slide hole of the fixed bracket through a hexagonal thread and a threaded sleeve, the fixed ball head at the other end of the steel wire rope is fixed to the hemispherical groove at the opening through the opening of the end of the fixing buckle, and the middle of the two ends of the steel wire rope is fixed to the steel wire rope bracket with a raised outer diameter on one side of the base plate through another hexagonal thread and another threaded sleeve.

[0010] The mechanical lock is a cylindrical lock, and the shaft core extending from the bottom of the cylindrical lock is connected to the fixed bracket. The mechanical lock is not limited to the cylindrical lock, and other locks such as electronic locks can also be used.

[0011] The utility model has a reasonable structural design, is easy to use and assemble, has good safety and stability, accurate monitoring, and is easy to operate manually or automatically. In particular, the emergency unlocking operation in which the fixed buckle is rotated by driving the wire rope through the mechanical lock is simple and convenient. The utility model is suitable for use as a multi-detection trigger electronic buckle lock, as well as a structural improvement of similar products. BRIEF DESCRIPTION OF THE DRAWINGS

The opening is provided with a lock buckle 9 which is fixed in the opening of the lock tongue by hitting one side of the opening of the lock tongue, and a lock tongue torsion spring 8 is provided at the rotating shaft of the lock tongue. The cover plate 15 corresponds to the shape of the bottom plate, and a corresponding U-shaped opening is provided on the unlocking side of the lock tongue; one end of the steel wire rope is connected to the fixed bracket 2 of the mechanical lock, and the other end of the steel wire rope is connected to one end of the fixed buckle 5; a lock tongue groove 501 is provided on the inner side of the other end of the fixed buckle for limiting the rotation of the other side of the opening of the lock tongue, and the lock tongue groove of the fixed buckle is fixed in the bottom plate for swinging, and the middle of the inner side between the connection between the fixed buckle and the steel wire 3 and the swing point is connected to the moving iron core of the electromagnet assembly, and the electromagnet assembly is connected to the PCB circuit board in the bottom plate through a line. A raised switch post 502 is located on the inner side of the retaining buckle. When the latch slot of the retaining buckle is unlocked and disengaged from the other side of the latch opening, the switch post of the retaining buckle abuts against and triggers the lock detection switch 6 in the base plate. The lock detection switch is connected to the PCB inside the base plate via wiring. The connection between the retaining buckle and the wire rope, and the connection between the retaining buckle and the moving iron core of the electromagnet assembly, extend out of both the base plate and the cover plate.

[0018] Two push rods 10 are provided on one side of the U-shaped opening of the base plate, each with one end extending outward. The other end of the push rod in the base plate is provided with a corresponding first door panel detection switch 12 and second door panel detection switch 13. The outer diameter of the push rod in the base plate is provided with a push rod spring 11 for resetting the push rod. The panel detection switch is connected to the PCB circuit board in the base plate via a circuit. The base plate is provided with a limit column for limiting the rotation of the lock tongue and the fixing buckle. The lock tongue and the fixing buckle corresponding to the limit column are respectively provided with a limit groove or a limit edge. One end of the wire rope is fixed to the adjustment slide hole of the fixed bracket via a hexagonal thread and a threaded sleeve. The fixed ball head at the other end of the wire rope is fixed to the hemispherical groove at the opening through the opening at the end of the fixing buckle. The middle of the two ends of the wire rope is fixed to the wire rope bracket with a raised outer diameter on one side of the base plate via another hexagonal thread and another threaded sleeve.

[0019] The mechanical lock is a cylindrical lock 1, and the shaft core extending from the bottom of the cylindrical lock is connected to the fixed bracket.

[0020] The electronic control unlocking method of the buckle lock is as follows: when the electromagnet assembly is given an action command, the moving iron core of the electromagnet assembly drives the fixed buckle to rotate, and the fixed buckle is separated from the lock tongue to perform the unlocking function; at this time, the lock buckle at the door panel 16 is pulled to complete the unlocking action, and the lock tongue rotates and disengages from the lock buckle; when closing the door, the lock buckle of the door panel hits and enters, and the lock buckle pushes the lock tongue to rotate inward. After the lock tongue pushes the fixed buckle to rotate, the lock tongue and the fixed buckle are reset, and the lock buckle can be buckled with the lock tongue.

[0021] The mechanical unlocking (emergency unlocking) of the hasp lock is achieved by rotating the cylindrical lock to drive the fixed bracket to rotate, and the fixed bracket drives the wire rope to pull the fixed buckle. According to the above-mentioned electronic control unlocking method, the fixed buckle can be separated from the lock tongue, and the lock tongue can swing freely.

[0022] In summary, this hasp lock utilizes door panel detection and trigger unlocking, facilitating emergency unlocking. This hasp lock is an integrated lock that implements both door and lock body detection, and also features a trigger unlocking function. The hasp lock utilizes a mechanical cylindrical lock to drive a wire rope for unlocking. The hasp lock features three switches: two door panel detection switches for lock body switch detection and door panel lock detection, and a third switch for door panel press triggering to unlock, ensuring safe unlocking without bouncing. Emergency unlocking is achieved by rotating the wire rope, mechanical cylindrical lock, and electronic hasp lock.
