This design increases the stability and reliability of the structure and avoids safety hazards caused by loose or falling knobs.

[0017] Beautiful and integrated: The hidden design allows the knob to be perfectly hidden inside the panel when not in use, without affecting the overall appearance, meeting the high requirements of modern users for beauty and concealment. The knob is integrated with the panel, with a simple and beautiful appearance, suitable for various high-end places.

[0018] The purpose of the utility model can also be solved by the following technical measures:

[0019] Furthermore, the outer wall of the knob seat is provided with an outer ring edge, the knob seat portion located above the outer ring edge forms the upper part of the knob seat, and the knob seat portion located below the outer ring edge forms the lower part of the knob seat.

[0020] Enhanced stability: The outer ring serves as the dividing line between the upper and lower parts of the knob seat, which enables the knob seat to have a better positioning and fixing effect when installed on the panel. The outer ring can fit the panel tightly to prevent the knob seat from shaking or loosening during use, thereby improving the stability and service life of the entire lock.

[0021] Simple installation and positioning: The design of the outer ring makes the installation and positioning of the knob seat simpler and clearer. During the installation process, the outer ring can be used as a limit device to ensure that the knob seat is accurately fixed in the installation opening of the panel, reducing installation errors and improving installation efficiency.

[0022] Prevent falling off: The upper part of the knob seat above the outer ring edge is inserted into the installation opening of the panel, and the panel blocks part of the entrance, further reducing the width of the entrance. The tight combination of the outer ring edge and the panel can effectively prevent the knob seat and the knob piece from falling off, ensuring the safety and reliability of the lock during use.

[0023] Simplified structural design: This design eliminates the complex shaft hole and shaft structure in traditional locks, making the overall structure of the lock simpler, easier to mass produce and assemble, and reducing production costs and manufacturing difficulty.

[0024] Furthermore, it also includes a supporting ring and a bolt, the lower part of the knob seat is inserted into the supporting ring until the outer ring edge abuts against the supporting ring, and the bolt passes through the supporting ring to lock the panel to fix the knob seat and the panel.

[0025] Enhanced fixing strength: The combination of the support ring and the bolt makes the connection between the knob seat and the panel more secure, avoiding loosening or falling off due to external force. The locking action of the bolt provides a strong fixing force to ensure the stability of the knob seat in long-term use.

[0026] Simplified installation process: The design of the support ring and bolts makes the installation process simpler and more intuitive. The user only needs to insert the lower part of the knob seat into the support ring, the outer ring edge against the support ring, and then fix the support ring to the panel with bolts to complete the installation. This design reduces the installation steps and improves the installation efficiency.

[0027] Easy maintenance: The bolt-fixed design makes disassembly and maintenance more convenient. When the lock needs to be repaired or replaced, you only need to unscrew the bolts to quickly disassemble the support ring and knob seat, which reduces maintenance time and operation difficulty and improves user experience.

[0028] Furthermore, the slide groove is a crescent-shaped slide groove.

[0029] Enhanced rotation smoothness: The arc design of the crescent-shaped slide makes the knob support slide more smoothly in the slide, reducing the resistance and friction during rotation. Users can feel a smoother feel when operating the knob, which improves the user experience.

[0030] Improve positioning accuracy: The curved shape of the crescent-shaped slide can accurately define the rotation path of the knob piece, so that the knob piece always remains within the preset track during rotation, avoiding deviation and shaking during rotation, and ensuring the precise fit between the knob piece and other parts of the lock.

[0031] Enhanced locking effect: The crescent-shaped slide can provide a natural locking effect when rotated into place. When the knob is rotated to a specific position, the pillar can be embedded in the arc-shaped end of the slide to play a locking role, preventing the knob from accidentally rotating due to external force, thereby improving the safety of the lock.

[0032] Easy to manufacture and install: The design of the crescent-shaped slide is relatively simple and can be easily realized through conventional manufacturing processes, which reduces the difficulty and cost of production. At the same time, during the installation process, you only need to align the support of the knob piece with the slide slot to achieve quick installation, which is convenient and practical.

[0033] Furthermore, the front center of the knob piece is hollowed out to form a deformation area, the front of the knob piece is located on both sides of the deformation area to form connecting arms, the pillars are arranged on the connecting arms, and the rear of the knob piece forms a grip.

[0034] Improve installation convenience: The design of the deformation area enables the knob piece to have elastic deformation ability during installation. The user can squeeze the knob piece to deform it and insert the pillar into the slide slot, and then the knob piece returns to its original shape to ensure that the pillar is firmly embedded in the slide slot. This design greatly simplifies the installation process and improves installation efficiency.

[0035] Enhance the elasticity and flexibility of the knob: By hollowing out the deformation area in the front center, the knob has better elasticity and deformation ability. The support on the connecting arm can slide smoothly in the slide slot during operation, which improves the rotation flexibility of the knob and makes the user operation smoother and more convenient.

[0036] Improved operating comfort: The design of the grip provides a more comfortable grip position, allowing users to better apply force when rotating or pressing the knob. The structural design of the deformation area and connecting arm makes operation more labor-saving and the user experience better.

[0037] Save materials and reduce costs: The hollow design reduces the amount of material used, while ensuring the functionality and structural strength, it reduces manufacturing costs and material costs, and improves the economic benefits of production.

[0038] The beneficial effects of the utility model are as follows:
