Description

Technical Field

[0001] This utility model relates to the field of door and window lock box technology, specifically a door and window lock box. Background Technology

[0002] In modern architecture and home furnishing, door and window locks are key components for security, and their performance directly affects the burglar resistance and user experience of doors and windows. The lock box, as the core component of door and window locks, plays a crucial role in housing the transmission components and realizing the locking function.

[0003] Existing door and window lock boxes have certain defects in their structural design and drive methods (such as the door and window lock transmission box disclosed in application number CN202221185212.8). Some lock boxes use a single drive structure, making it difficult to achieve synchronous extension of the driving plate and driven plate from both ends of the fixed base shell when they move, resulting in less smooth locking operation and affecting efficiency. Furthermore, traditional drive structures are prone to jamming during transmission due to insufficient precision in the cooperation between transmission components, which not only reduces the service life of the door and window lock but also produces unpleasant noises. In addition, the extension length of the driving plate and driven plate in existing lock boxes is limited, which cannot meet the sufficient locking depth requirements in some special application scenarios, affecting the anti-theft performance and security of doors and windows. Therefore, it is urgent to improve the structure of existing door and window lock boxes to enhance their performance and reliability. Utility Model Content

It also includes a transmission gear rotatably connected to the fixed base shell. The drive plate includes a drive plate and a driven plate. A drive rack and a driven rack are respectively provided on one end of the drive plate and the driven plate. An extension portion extends from the other end of the drive plate and the driven plate through an inclined surface. The drive rack and the driven rack are respectively provided on both sides of the transmission gear and are meshed with the transmission gear for transmission. A drive portion connected to the drive plate is provided on the drive wheel.

[0006] Furthermore, the drive unit is provided with a mounting shaft on one side of the drive plate, a roller is mounted on one end of the mounting shaft, the drive plate is provided with a slot for adapting and connecting with the mounting shaft, thickening plates are provided on both sides of the slot, and vertical surfaces are provided on the thickening plates for rolling cooperation with the roller.

[0007] Furthermore, the bottom of the thickened plate has a plug-in block, and the two sides of the slot are provided with plug-in ports for plugging into the plug-in block.

[0008] Furthermore, the fixed base shell includes a "U"-shaped frame and a cover that fits onto the "U"-shaped frame. Guide grooves are provided at both ends of the cover, and guide posts that slide in cooperation with the guide grooves are provided on the active plate and the driven plate.

[0009] Furthermore, the lock box includes a left box block, a right box block, and clamping plates disposed on both sides of the left and right box blocks, and a rotating groove for rotating with the drive wheel is provided between the left and right box blocks.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0022] This utility model provides a door and window lock box.

[0023] In this embodiment, refer to Figure 1-4 The door and window lock box includes a fixed base shell 1, a lock box 2 fixed on the fixed base shell 1, a drive wheel 3 installed in the lock box 2, and a drive plate 4 driven by the drive wheel 3 to move synchronously. It also includes a transmission gear 5 rotatably connected to the fixed base shell. The drive plate includes a drive plate 6 and a driven plate 7. A drive rack 8 and a driven rack 9 are respectively provided on one end of the drive plate and the driven plate. An extension portion 11 extends from the other end of the drive plate 6 and the driven plate 7 through an inclined surface 10. The drive rack 8 and the driven rack 9 are respectively located on both sides of the transmission gear and are meshed with the transmission gear. A drive part 12 connected to the drive plate is provided on the drive wheel.

[0024] In this embodiment, based on a traditional door and window lock box, a transmission gear rotatably connected to the fixed base shell is added. The drive plate is split into a driving plate and a driven plate, with a driving rack and a driven rack respectively installed at one end of each plate. The two racks are positioned on opposite sides of the transmission gear and mesh with it. The driving wheel is connected to the driving rack of the driving plate through a drive unit. When the driving wheel rotates, it drives the driving rack to move. The driving rack meshes with the transmission gear, causing the transmission gear to rotate, which in turn drives the driven rack to move, so that the driving plate and the driven plate extend synchronously from both ends of the fixed base shell.

[0025] Through the meshing transmission of gears and racks, the driving plate and the driven plate extend synchronously, improving the smoothness and efficiency of the locking operation. Compared with other transmission methods, gear and rack transmission provides more uniform force and smoother transmission, reducing jamming and the possibility of abnormal noise. The extensions on the driving plate and the driven plate have increased extension length, which can meet the requirements of door and window locking depth in special scenarios and enhance anti-theft performance.

[0026] Specifically, the drive unit is provided with a mounting shaft 13 on one side of the drive plate, and a roller 14 is mounted on one end of the mounting shaft 13. The drive plate is provided with a slot 15 that is adapted to connect with the mounting shaft. Thickening plates 16 are provided on both sides of the slot 15, and vertical surfaces 17 that are rolled with the roller are provided on the thickening plates 16.

[0027] In this embodiment, a mounting shaft is provided on one side of the drive unit of the drive wheel, and a roller is mounted on the end of the shaft. A slot adapted to the mounting shaft is formed on the drive plate, and thickening plates are provided on both sides of the slot. The thickening plates have vertical surfaces that roll in cooperation with the roller. When the drive wheel rotates, the drive unit drives the mounting shaft to move, and the roller rolls on the vertical surface of the thickening plate, thereby converting the rotation of the drive wheel into linear movement of the drive plate. At the same time, the adaptive connection between the mounting shaft and the slot ensures the stability and reliability of the movement, ensuring the accuracy of power transmission during the transmission process.

[0028] Specifically, the bottom of the thickened plate has a plug-in block 18, and the two sides of the slot are provided with plug-in ports 19 for plugging and connecting with the plug-in block 18.

[0029] In this embodiment, a plug-in block is provided at the bottom of the thickened plate, and corresponding sockets are provided on both sides of the slot of the active plate. During installation, the plug-in block of the thickened plate is inserted into the socket of the slot to achieve a stable connection between the thickened plate and the active plate, ensuring that the thickened plate will not loosen or shift during transmission and maintaining stable rolling contact between the roller and the vertical surface. The plug-in connection method facilitates the installation and disassembly of the thickened plate, making it convenient to assemble and replace components during production and maintenance. At the same time, this tight connection structure ensures the stability of the thickened plate during long-term use of door and window locks, further improving the reliability of roller transmission and reducing transmission failures caused by loose components.

[0030] Specifically, the fixed base shell includes a U-shaped frame 20 and a cover 21 that covers the U-shaped frame 20. The cover 21 has guide grooves 22 at both ends, and the active plate and the driven plate are provided with guide posts 23 that slide in cooperation with the guide grooves.

[0031] In this embodiment, the fixed base shell consists of a U-shaped frame and a cover. Guide grooves are provided at both ends of the cover, and guide posts are provided on the driving plate and driven plate, which slide in conjunction with the guide grooves. When the driving plate and driven plate move during transmission, the guide posts slide along the guide grooves, guiding their movement and restricting their direction of motion, ensuring they can only move in a straight line along a fixed trajectory. The cooperation between the guide grooves and guide posts effectively prevents the driving plate and driven plate from shifting or wobbling during movement, ensuring the accuracy and stability of the transmission.

[0032] Specifically, the lock box includes a left box block 24, a right box block 25, and clamping plates 26 disposed on both sides of the left and right box blocks. A rotating groove 27 for rotating with the drive wheel is provided between the left and right box blocks.

[0033] In this embodiment, the lock box consists of a left box block, a right box block, and two side plates. A rotating groove is provided between the left and right box blocks, and the drive wheel is installed in the rotating groove and can rotate within it. When driven, the drive wheel can rotate freely within the rotating groove. It is connected to the drive rack through the drive unit, converting the rotational motion into the linear motion of the drive plate, thereby realizing the locking function of the door and window lock.

[0034] Specifically, the left box block, the right box block, and the clamping plate are provided with sliding grooves 29 for installing the inner top block 28 at both ends. One end of the inner top block is provided with a fixing hole 30, and the other end is provided with a nut hole 31.

[0035] In this embodiment, sliding grooves are provided at both ends of the left box block, the right box block, and the clamping plate. The inner top block is installed in the sliding groove, and a fixing hole is provided at one end of the inner top block, while a nut hole is provided at the other end. By installing corresponding fasteners in the fixing hole and the nut hole, the inner top block can be fixed in a suitable position.

[0036] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
