Description

Technical Field

[0001] This utility model relates to the field of padlock technology, specifically a high-security anti-drag padlock. Background Technology

[0002] Padlocks are a common type of lock that achieves locking through the cooperation of the shackle (a hook-shaped metal part) and the lock body. They are characterized by simple structure, portability, ease of use, and wide application. However, in scenarios with stringent requirements for preventing forced entry, such as warehousing and logistics and energy facilities, the security of padlocks needs to be further improved, and they need to have sufficient strength to prevent violent damage.

[0003] To address this, China Patent Network has disclosed a secure smart padlock with application number 201920915720.9. By scanning the QR code displayed on the screen, if the user has the necessary permissions, the drive device is triggered to retract the limit bolt, thus opening the padlock. If the user does not have the necessary permissions, the padlock will not open. The user's permissions can be stored in the padlock via a communication module or directly on the Internet for online permission verification. By installing sensors, the padlock's locking and unlocking status is monitored periodically. If the opening time exceeds the operation time specified in the application, a buzzer will sound an alarm. This design offers advantages such as high difficulty in cracking permissions and ease of operation, avoiding problems caused by lost keys or blurred fingerprints.

[0004] While the above-mentioned applications meet the user's needs to a certain extent, there are still some defects in the use process. The specific problems are as follows: Since most padlocks adopt a single-point locking structure of "U-shaped lock hook + straight-insertion lock tongue", the lock beam is only locked in the vertical direction by the lock tongue. When subjected to horizontal pulling force, the engagement point between the lock tongue and the lock beam becomes the only force point. It is very easy for the lock tongue to deform or break due to the concentrated pulling force. Based on this, this utility model designs a high-security anti-pull-out padlock to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a high-security anti-pull-off padlock to solve the problem mentioned in the background art, which is that since most padlocks adopt a single-point locking structure of "U-shaped lock hook + straight-insertion lock tongue", the lock beam is only locked in the vertical direction by the lock tongue. When subjected to horizontal pull-off force, the engagement point between the lock tongue and the lock beam becomes the only force point, which is very easy to cause deformation or breakage of the lock tongue due to the concentration of pull-off force.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-security anti-pull-off padlock, comprising a lock body, wherein an anti-pull-off warning component is installed at the top of the lock body, and the anti-pull-off warning component comprises a lock hook, a pressure sensor, a first electromagnet, a second electromagnet, and a lock cylinder;

[0007] The lock body is rotatably connected to a lock hook, and a second electromagnet is fixedly connected to one side of the lock hook. A pressure sensor is fixedly installed at the top of the lock body, and a first electromagnet is fixedly installed at the top of the pressure sensor. The lock body is rotatably connected to a lock cylinder, which can further enhance the stability of the connection between the lock body and the lock hook and avoid the problem of the lock tongue being deformed or broken when subjected to horizontal pulling force.

[0008] The bottom of the lock body is equipped with a dustproof limiting component, which includes a dustproof plate, a push plate, and a fixing compartment.

[0009] A dustproof plate is slidably connected to the bottom of the lock body, and a push plate is fixedly connected to one side of the dustproof plate. A fixed compartment is fixedly connected to the bottom of the lock body, which can cover the lock cylinder and the key hole, effectively preventing foreign objects such as dust and insects from entering, and avoiding the lock cylinder from becoming unusable due to dust accumulation or insects blocking the key hole.

[0010] Preferably, the anti-detachment warning assembly further includes a warning light, a buzzer, a keyhole, a connecting block, and a switch;

[0011] Two warning lights and a buzzer are fixedly connected to both sides of the lock body. The lock cylinder has a lock hole inside. A connecting block is fixedly connected to one side of the lock cylinder. A switch is fixedly installed inside the lock body.

[0012] Preferably, the dustproof limiting assembly further includes a T-shaped rod, a limiting plate, a limiting block, and a return spring;

[0013] The fixed chamber is internally slidably connected to a T-shaped rod, one side of which is fixedly connected to a limit plate, and the outer side of which is fixedly sleeved with a limit block. A return spring is fixedly connected internally to the fixed chamber.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The anti-loosening warning component can further enhance the stability of the connection between the lock body and the lock hook, avoiding the problem of deformation or breakage of the lock tongue when subjected to horizontal pulling force. At the same time, when subjected to pulling force, the first electromagnet and the second electromagnet transmit the pulling force to the pressure sensor, and the pressure sensor turns on the warning light and buzzer to sound an alarm, further improving the safety performance of the lock body and lock hook.

[0016] 2. The dustproof limiting component can cover the lock cylinder and keyhole, effectively preventing dust, insects and other foreign objects from entering, avoiding the lock cylinder from becoming unusable due to dust accumulation or insects blocking the keyhole. At the same time, by pushing the T-shaped rod, the limiting plate can be embedded into the push plate, limiting the push plate and dustproof plate, ensuring the stability of the dustproof plate.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5This utility model provides a technical solution: a high-security anti-pull-off padlock, including a lock body 1, with an anti-pull-off warning component 2 installed on the top of the lock body 1. The anti-pull-off warning component 2 includes a lock hook 201, a pressure sensor 202, a first electromagnet 203, a second electromagnet 204, and a lock cylinder 207.

[0029] A lock hook 201 is rotatably connected inside the lock body 1. A second electromagnet 204 is fixedly connected to one side of the lock hook 201. A pressure sensor 202 is fixedly installed at the top of the lock body 1. A first electromagnet 203 is fixedly installed at the top of the pressure sensor 202. The first electromagnet 203 and the second electromagnet 204 are magnetically attracted to each other. When the first electromagnet 203 and the second electromagnet 204 are energized, they are magnetically repelled. A lock cylinder 207 is rotatably connected inside the lock body 1.

[0030] The bottom of the lock body 1 is equipped with a dustproof limiting component 3, which includes a dustproof plate 301, a push plate 302 and a fixed compartment 303.

[0031] A dustproof plate 301 is slidably connected to the bottom of the lock body 1. Two sliders are fixedly connected to the top of the dustproof plate 301. The outer side of the sliders is slidably connected to the inside of the lock body 1. A push plate 302 is fixedly connected to one side of the dustproof plate 301. A limit hole is opened inside the push plate 302. A fixed chamber 303 is fixedly connected to the bottom of the lock body 1.

[0032] The anti-detachment warning assembly 2 also includes a warning light 205, a buzzer 206, a keyhole 208, a connecting block 209, and a switch 210;

[0033] Two warning lights 205 and a buzzer 206 are fixedly connected to both sides of the lock body 1. The warning lights 205 and the buzzer 206 are electrically connected to the pressure sensor 202. The lock cylinder 207 has a lock hole 208 inside. A connecting block 209 is fixedly connected to one side of the lock cylinder 207. A switch 210 is fixedly installed inside the lock body 1. The switch 210 is electrically connected to the first electromagnet 203 and the second electromagnet 204, so that the first electromagnet 203 and the second electromagnet 204 can be separated when the lock hook 201 is opened with a key.

[0034] The lock can be closed by inserting one end of the lock hook 201 into the lock body 1. When the lock hook 201 generates an external pulling force, the lock hook 201 drives the first electromagnet 203 and the second electromagnet 204 to generate an upward pulling force. The second electromagnet 204 transmits the pulling force to the pressure sensor 202. When the pressure sensor 202 receives the signal, the warning light 205 flashes and the buzzer 206 sounds an alarm to remind the staff and provide real-time warning of potential forced entry, realizing an upgrade from passive protection to active warning. When the staff inserts the key into the keyhole 208 and turns the lock cylinder 207, the lock cylinder 207 drives the connecting block 209 to move. The connecting block 209 touches the switch 210, and the switch 210 energizes the first electromagnet 203 and the second electromagnet 204. The first electromagnet 203 and the second electromagnet 204 repel each other magnetically, and the lock can be opened.

[0035] The dustproof limiting assembly 3 also includes a T-shaped rod 304, a limiting plate 305, a limiting block 306, and a return spring 307;

[0036] A T-shaped rod 304 is slidably connected inside the fixed chamber 303. A limit plate 305 is fixedly connected to one side of the T-shaped rod 304, and a limit block 306 is fixedly sleeved on the outside of the T-shaped rod 304. A return spring 307 is fixedly connected inside the fixed chamber 303. One side of the return spring 307 abuts against one side of the limit block 306, so that the T-shaped rod 304 can drive the limit block 306 to rotate inside the fixed chamber 303 while also driving the limit block 306 to move horizontally.

[0037] Pulling the push plate 302 causes the dustproof plate 301 to move, covering the bottom of the lock cylinder 207 and the lock hole 208, effectively preventing dust, insects, and other foreign objects from entering and preventing the lock cylinder 207 from becoming unusable due to dust accumulation or insects blocking the lock hole 208. Rotating the T-shaped rod 304 causes the limiting plate 305 and the limiting block 306 to rotate, and the limiting plate 305 embeds into the limiting hole of the push plate 302. Continuing to rotate... The T-shaped rod 304 causes the limiting plate 305 to rotate inside the push plate 302. After rotating to the appropriate position, the limiting plate 305 limits the push plate 302 to prevent the dustproof plate 301 from shifting. Similarly, when it is necessary to open the dustproof plate 301, rotate the T-shaped rod 304 and the limiting plate 305 so that the limiting plate 305 separates from the push plate 302 through the limiting hole. Pulling the T-shaped rod 304 will open the dustproof plate 301.
