Description

Technical Field

[0001] This utility model relates to the field of door lock technology, and in particular to an anti-pry mechanical handle lock. Background Technology

[0002] In daily life, mechanical locks such as door locks and cabinet locks are widely used in residences, offices and warehouses, mainly to protect property and privacy. Traditional mechanical locks usually consist of a lock body, keyhole, lock cylinder mechanism and handle assembly. Their core function is to control the extension and retraction of the bolt with a key to open and close the door or cabinet. Such locks have long dominated the market due to their mature structure, low cost and easy operation.

[0003] However, with the development of society and the economy and the improvement of people's security awareness, traditional mechanical locks have gradually revealed many shortcomings when facing increasingly complex security needs: First, most ordinary mechanical handle locks have a relatively simple structural design, relying only on the lock cylinder and bolt to achieve the locking function, lacking an effective anti-pry protection mechanism. The lock cylinder can be pried open by external force, posing a significant security risk and failing to meet the basic anti-theft performance requirements of modern homes, commercial venues, and public facilities; Second, traditional mechanical locks cannot promptly issue alarms to users when subjected to illegal prying or violent damage, causing users to often only notice the abnormality after the incident occurs, missing the opportunity to take immediate countermeasures, which may lead to increased property losses or even serious security accidents.

[0004] Therefore, a mechanical handle lock with anti-pry protection and alarm functions needs to be developed. Utility Model Content

[0005] In order to overcome the shortcomings of existing mechanical handle locks, such as weak anti-pry performance and inability to promptly issue alarms to users when subjected to illegal prying or violent damage, this utility model provides a mechanical handle lock with anti-pry protection and alarm functions.

[0006] To address the aforementioned issues, this utility model employs the following technical solution: an anti-pry mechanical handle lock, comprising a mechanical lock body, with handles movably mounted on both the front and rear sides of the mechanical lock body. A movable groove is formed on the rear side of the lock hole of the mechanical lock body, with a guide rod fixedly connected to the lower part of the movable groove. A magnetic stop and a ferrous stop are slidably mounted on the guide rod, and the magnetic stop and the ferrous stop are respectively connected to the inner wall of the movable groove via springs. Symmetrically distributed locking blocks are provided on the side of the magnetic stop that contacts the ferrous stop, and locking holes matching the locking blocks are formed on the ferrous stop. A sliding groove is formed on the side of the mechanical lock body, with a push block slidably mounted inside the sliding groove. The push block is connected to the magnetic stop via a pull rope. An alarm is embedded in the middle of the mechanical lock body, with an open button at the bottom of the alarm and an close button on the side of the alarm.

[0007] Furthermore, the handle is covered with an anti-slip sleeve.

[0008] Furthermore, a protective plate is rotatably mounted on the side of the mechanical lock body via a pivot, a first magnetic block is embedded in the mechanical lock body above the protective plate, and a second magnetic block corresponding to the first magnetic block is embedded in the top of the protective plate.

[0009] Furthermore, a protective shell is provided in the middle of the mechanical lock body, which covers the location of the alarm.

[0010] Furthermore, a rubber sleeve is provided at the sliding connection between the magnetic stop and the guide rod.

[0011] Furthermore, the bottom of the push block has an anti-slip block.

[0012] Compared with the prior art, this utility model has the following technical effects: 1. By setting up a magnetic stop and a ferrous stop, the magnetic attraction between the two and the cooperation between the block and the hole form a locking mechanism, thereby closing the lock cylinder and preventing the lock cylinder from being illegally opened, thus significantly improving the overall anti-pry performance. In addition, when illegally pried, the magnetic stop will detach from the ferrous stop due to external force and slide to the right, which will trigger the open button at the bottom of the alarm, causing the alarm to start automatically and emit an audible and visual alarm, promptly reminding the user or people around to pay attention to the abnormal situation, playing an effective anti-theft warning role, and making up for the defect of traditional mechanical locks without an alarm mechanism.

[0013] 2. A protective plate is rotatably mounted on the side of the mechanical lock body via a pivot, and a first magnetic block and a second magnetic block that attract each other are set between the lock body and the protective plate. Under normal conditions, the protective plate blocks the slide groove to prevent foreign objects from entering or malicious operation of the push block, forming an additional physical barrier and further improving the security level of the device.

Detailed Implementation

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1: Please refer to Figures 1-4A pry-resistant mechanical handle lock includes a mechanical lock body 1, with handles 2 movably mounted on both the front and rear sides of the mechanical lock body 1. Each handle 2 is covered with an anti-slip sleeve 13 made of rubber or silicone to improve grip comfort and prevent slippage. A movable groove is formed on the rear side of the lock hole of the mechanical lock body 1. A guide rod 3 is fixedly connected to the lower part of the movable groove. A magnetic stop 4 and a ferroelectric stop 6 are slidably mounted on the guide rod 3. The magnetic stop 4 and the ferroelectric stop 6 can attract each other to achieve initial locking. The magnetic stop 4 and the ferroelectric stop 6 are respectively spring-loaded... Spring 7 is connected to the inner wall of the movable groove, allowing it to maintain an adsorption state without external force. Furthermore, a rubber sleeve 19 is provided at the sliding connection between the magnetic stop 4 and the guide rod 3 to increase friction and ensure stable sliding of the magnetic stop 4. A symmetrically distributed locking block 5 is provided on the side of the magnetic stop 4 that contacts the ferrous stop 6. Two locking holes matching the locking blocks 5 are provided on the ferrous stop 6. The locking blocks 5 engage with the locking holes to form a stable locking state, thereby closing the lock cylinder and preventing it from being illegally opened. A sliding groove is provided on the side of the mechanical lock body 1, and a sliding mechanism is installed inside the groove. A push block 8 is provided, which can slide up and down along the inside of the slide groove. The push block 8 is connected to the magnetic stop 4 by a pull rope 9. When the push block 8 is pushed upward, the pull rope 9 is pulled, causing the magnetic stop 4 to slide to the right against the force of the spring 7, disengaging from the iron stop 6 and releasing the locked state. The bottom of the push block 8 has an anti-slip block 20, which has uneven textured bottom to increase the friction between the finger and the anti-slip block 20, making it easier for the user to accurately operate the push block 8. An alarm 10 is embedded in the middle of the mechanical lock body 1, which can emit a high-decibel alarm when triggered. To serve as an effective deterrent, the alarm 10 has an activation button 11 at its bottom. When the magnetic block 4 is disengaged from the ferrous block 6 by external force and slides to the right, it will touch the activation button 11, thereby activating the alarm 10. The alarm 10 also has a deactivation button 12 on its side. When the push block 8 moves upward and its top contacts the deactivation button 12, the alarm 10 will enter the deactivation state, ensuring that the alarm is not triggered during normal unlocking. The mechanical lock body 1 has a protective shell 18 in the middle, which covers the location of the alarm 10 and protects it from damage by external forces.

[0022] When no unlocking operation is performed, the mechanical lock is in the locked state. At this time, the magnetic stop 4 and the iron stop 6 are tightly pressed together under the action of the spring 7. The locking block 5 on the magnetic stop 4 is inserted into the locking hole of the iron stop 6, forming a stable mechanical connection to prevent the lock cylinder from being easily opened. If someone attempts to illegally pry open the lock cylinder with external force, the magnetic stop 4 may slide to the right due to structural deformation or force, disengaging from the iron stop 6. As the magnetic stop 4 moves to the right, it will eventually contact the unlock button 11 at the bottom of the alarm 10, thereby triggering the alarm 10 to start. After the alarm 10 is activated, it will emit an audible alarm to alert the user or people around to abnormal situations, playing a role in theft prevention and deterrence. When the lock-picking operation ends, the magnetic stop 4 will automatically return to its original position under the action of the spring 7 and re-attach to the iron stop 6. The alarm 10 automatically shuts off after a set time. When the user uses the key to legally unlock the device, the alarm system should be deactivated and the locking mechanism opened first. The user slides the push block 8 upward in the slide groove. The push block 8 contacts the off button 12 on the side of the alarm 10, putting the alarm 10 into the off state to avoid accidental triggering. During the upward movement of the push block 8, the pull rope 9 connected to it pulls the magnetic stop 4 to the right, causing it to disengage from the ferrous stop 6. At this time, the locking block 5 disengages from the locking hole, and the mechanical connection between the magnetic stop 4 and the ferrous stop 6 is released. After the locking mechanism is released, the user can insert the key normally to unlock the device. After the user has legally unlocked the device, the push block 8 is pulled down to reset the device. The pull rope 9 no longer pulls the magnetic stop 4. At this time, the magnetic stop 4 automatically returns to its original position with the assistance of the spring 7.

[0023] Example 2: Based on Example 1, please refer to... Figure 5 A protective plate 15 is rotatably mounted on the side of the mechanical lock body 1 via a pivot 14. The protective plate 15 can cover the slide rail when closed to prevent foreign objects from entering or maliciously operating the push block 8 in the slide rail. A first magnetic block 16 is embedded in the mechanical lock body 1 above the protective plate 15, and a second magnetic block 17 corresponding to the first magnetic block 16 is embedded on the top of the protective plate 15.

[0024] Under normal circumstances, the protective plate 15 remains closed, blocking the slide rail. At this time, the second magnetic block 17 on the protective plate 15 attracts the first magnetic block 16 on the mechanical lock body 1, making the protective plate 15 tightly fit against the side of the mechanical lock body 1, preventing unauthorized operators from contacting the push block 8 inside the slide rail, thus adding an extra layer of security. When the user needs to perform a legal unlocking operation, they must first manually pull down the protective plate 15, causing it to rotate outward around the pivot 14. As the protective plate 15 rotates, the second magnetic block 17 leaves the effective attraction range of the first magnetic block 16, releasing the attraction between the two, thereby allowing the protective plate 15 to open completely. After the protective plate 15 is opened, the user can operate the push block 8. After completing the operation, the protective plate 15 is snapped back into place, and the magnetic force between the first magnetic block 16 and the second magnetic block 17 is used to fix it, restoring it to the initial security protection state.

[0025] It should be understood that this embodiment is for illustrative purposes only and is not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the invention, and these equivalent forms also fall within the scope defined by the appended claims.
