Abstract
Description
Technical Field
[0001] This utility model relates to the field of smart lock technology, specifically to a smart lock body with a dual anti-pry structure. Background Technology
[0002] Smart locks are locks that are improved upon traditional mechanical locks, offering greater intelligence and convenience in terms of user security, identification, and management. Smart locks are the locking components in access control systems. Unlike traditional mechanical locks, smart locks are composite locks that combine security, convenience, and advanced technology.
[0003] Currently, smart locks typically incorporate a pressure sensor between the lock body and the door panel. When the smart lock is pried open, the pressure between the lock body and the door panel decreases, triggering a buzzer to warn and scare the user away. However, relying solely on this single anti-pry structure means that when no one is around, unauthorized individuals can continue to pry open the lock regardless of the sound, rendering the anti-pry effect relatively weak. Utility Model Content
[0004] The purpose of this invention is to provide an intelligent lock body with a dual anti-pry structure to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a smart lock body with a double anti-pry structure, comprising a smart lock body and a reinforcing component. A handle is provided on one side of the smart lock body, and a threaded cylinder is provided on the other side of the smart lock body. The reinforcing component is provided at the upper and lower ends of the smart lock body, and the reinforcing component includes a slide groove, a slide rod, a spring, a slider, and a locking plate. The upper and lower ends of the other side of the smart lock body are provided with slide grooves, and a slide rod is provided inside the slide grooves. A spring is sleeved on the outside of the slide rod, and a slider is connected to the end of the spring. A locking plate is fixed on one side of the slider.
[0006] Furthermore, the spring abuts against the smart lock body, and the smart lock body is slidably connected to the slide bar.
[0007] Furthermore, the slider is T-shaped and is fixedly connected to the slide rod.
[0008] Furthermore, the number of the slide grooves is set to four, and the slider is slidably connected to the smart lock body through the slide grooves.
[0009] Furthermore, the cross-section of the card plate is a right trapezoid, and the sliders are symmetrically distributed about the center line of the card plate.
[0010] Furthermore, one end of the card plate is connected to a pull rope, and a rotating sleeve is fixed to the end of the pull rope.
[0011] Furthermore, the rotating sleeve is rotatably connected to the threaded cylinder, and there are two threaded cylinders.
[0012] Furthermore, a protective rubber ring is fixed to the outer end of the smart lock body, and the protective rubber ring is rectangular.
[0013] This utility model provides an intelligent lock body with a dual anti-pry structure, which has the following beneficial effects:
[0014] 1. By setting up a reinforcement component, this utility model allows for easy installation of the smart lock body. First, corresponding locking holes are made on the security door. Then, when the threaded cylinder is inserted into the security door, the locking holes push the inclined part of the locking plate, compressing the spring. After insertion, the spring pushes the slider to hook the locking plate onto the inside of the security door. Therefore, after complete installation, the locking plate reinforces both the upper and lower ends of the smart lock body. Compared to existing smart lock bodies that rely solely on bolts and threaded cylinders to connect to the security door, this application offers higher stability and better anti-pry performance.
[0015] 2. This utility model, through the design of the pull rope, allows for easy disassembly and replacement of the smart lock body during maintenance. Simply rotate the rotating sleeve on the other side of the security door to rewind the pull rope, thereby pulling the locking plate to move and quickly release the restriction between the locking plate and the security door panel, facilitating disassembly and replacement. Furthermore, during use, a protective rubber ring can be used to protect the exterior of the smart lock body. When unauthorized individuals try to pry at the edges of the smart lock body, they will first pry at the protective rubber ring. Since the protective rubber ring is made of flexible material, it will deform, thus weakening the prying force. It also obstructs the view, preventing unauthorized individuals from observing whether the pry bar is in contact with the edges of the smart lock body. Only after completely breaking the protective rubber ring can the next prying operation be carried out, thus providing a certain degree of anti-pry performance. Attached Figure Description

[0020] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0021] like Figures 1 to 3 As shown, a smart lock body with a double anti-pry structure includes a smart lock body 1 and a reinforcing component 4. A handle 2 is provided on one side of the smart lock body 1, and a threaded cylinder 3 is installed on the other side. A bolt is installed inside the threaded cylinder 3 on the other side of the security door to fix the smart lock body 1. The reinforcing component 4 is located at the upper and lower ends of the smart lock body 1 and includes a groove 401, a sliding rod 402, a spring 403, a slider 404, and a locking plate 405. The other side of the smart lock body 1 has grooves 401 at both the upper and lower ends, with a sliding rod 402 inside the grooves 401. A spring 403 is sleeved on the outside of the sliding rod 402, and a slider 404 is connected to the end of the spring 403. The spring 403 abuts against the smart lock body 1, and the smart lock body 1 is slidably connected to the sliding rod 402. The smart lock body 1 will press against one end of the spring 403. The slider 404 has a T-shaped T-shaped slider that is fixedly connected to the slide bar 402. Multiple sliders 404 can improve the overall connection strength. There are four slide grooves 401, and the slider 404 is slidably connected to the smart lock body 1 through the slide grooves 401. The slide grooves 401 limit and guide the slider 404. The cross-section of the plate 405 is a right trapezoid, and the sliders 404 are symmetrically distributed about the center line of the plate 405. When installing the smart lock body 1, it is only necessary to first open the corresponding card hole on the security door. Then, when the threaded cylinder 3 is inserted into the security door, the card hole will push the inclined part of the plate 405, compressing the spring 403. After insertion, the spring 403 will push the slider 404 to make the plate 405 hook onto the inside of the security door, thereby reinforcing the upper and lower ends of the smart lock body 1.
[0022] like Figure 2 and Figure 3As shown, one end of the locking plate 405 is connected to a pull rope 5, and the end of the pull rope 5 is fixed with a rotating sleeve 6. The rotating sleeve 6 is rotatably connected to a threaded cylinder 3, and there are two threaded cylinders 3. Rotating the rotating sleeve 6 on the other side of the security door can wind up the pull rope 5, thereby pulling the locking plate 405 to move, quickly releasing the restriction between the locking plate 405 and the security door panel, making it convenient to disassemble and replace. The outer end of the smart lock body 1 is fixed with a protective rubber ring 7, and the protective rubber ring 7 is rectangular. The protective rubber ring 7 is used to protect the exterior of the smart lock body 1. When an unauthorized person pries from the corner of the smart lock body 1, they will first pry the protective rubber ring 7. At the same time, the protective rubber ring 7 is made of flexible material and will deform, thereby weakening the prying force. It can also block the view, preventing unauthorized persons from observing whether the pry bar is in contact with the corner of the smart lock body 1.
[0023] In summary, this smart lock body with a dual anti-pry structure, when used, first according to... Figure 1 , Figure 2 and Figure 3 The structure shown involves first creating corresponding locking holes for the locking plate 405 on the security door. Then, when the threaded cylinder 3 is inserted into the security door, the locking holes push the inclined portion of the locking plate 405, compressing the spring 403. After insertion, the spring 403, limited by the slide groove 401 and the slide rod 402, pushes the slider 404, causing the locking plate 405 to hook onto the inside of the security door. Next, bolts are installed inside the threaded cylinder 3 on the other side of the security door to secure the smart lock body 1. During use, when unauthorized individuals try to pry open the smart lock body 1 from the corners, they will first pry open the protective rubber ring 7. Since the protective rubber ring 7 is made of flexible material, it will deform, thus weakening the prying force. At the same time, it can also block the line of sight, preventing criminals from observing whether the pry bar is in contact with the corners of the smart lock body 1. Only after the protective rubber ring 7 is completely broken can the next prying operation be carried out. Even when prying the corners, the upper and lower ends of the smart lock body 1 are reinforced by the clamping plate 405. Compared with the existing smart lock body which is only connected to the security door by bolts and threaded cylinder 3, this application has higher stability and better anti-pry performance. Finally, when it is necessary to disassemble and replace the smart lock body 1, simply rotate the rotating sleeve 6 on the other side of the security door to rewind the pull rope 5, thereby pulling the clamping plate 405 to move, quickly releasing the restriction between the clamping plate 405 and the security door panel, making it convenient to disassemble and replace.
