Description

Technical Field

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

[0002] Lever handle locks are door locks that integrate the functions of a door handle and a lock, offering convenience, security, durability, and aesthetics. They are widely used in residential, commercial, office, and public places. Featuring a lever-type handle design, they are more ergonomic than traditional knob locks, allowing for easy one-handed operation and improved unlocking convenience. Furthermore, lever handle locks are compact, easy to install, suitable for various door types, and can be combined with mechanical keys, passwords, fingerprints, facial recognition, and other unlocking methods to meet the needs of different users. They offer strong security, with optional anti-theft, fireproof, and escape functions, especially effective in high-security environments such as office buildings, hotels, apartments, and fire door systems, enhancing access control capabilities. In addition, lever handle locks come in various designs to match different interior design styles, improving both the practicality of the lock and the overall aesthetics of the space, making them an important part of modern door lock systems.

[0003] Traditional lever locks, such as the Chinese utility model patent with publication number "CN107060495A" entitled "A Baseless Lever and Lock," mainly involve a central through hole in the rotating wheel and a threaded hole in the rotating wheel seat. A screw passes through the central through hole and connects to the threaded hole. The opposing end faces of the rotating wheel and the rotating wheel seat are respectively provided with a locking component, a locking hole, and a blind hole, so that the rotating wheel and the rotating wheel seat can lock or unlock when rotating. However, this technical solution has the problem that when the connection between the screw and the threaded hole is loose, it will affect the locking effect of the locking pin and the locking hole. Moreover, the tightness of the connection between the screw and the threaded hole will result in different forces required for the user to rotate the handle, which will bring a bad user experience. Utility Model Content

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] This embodiment relates to a baseless handle and a lock, see reference. Figures 1-7The device includes a rotating wheel 100 and a rotating wheel seat 200. One end of the rotating wheel 100 has a protruding locking portion 110, and the locking portion 110 has multiple locking holes 111 and unlocking holes 112 spaced apart around its periphery. One end of the rotating wheel seat 200 has a recessed first mounting groove 210, and the side wall of the first mounting groove 210 has multiple mounting holes 220. An elastic element 230 and a locking bead 240 are disposed within each mounting hole 220. One end of the elastic element 230 acts on the bottom of the mounting hole 220. The other end of 30 acts on the locking bead 240; when the locking bead 240 enters the locking hole 111 under the elastic force of the elastic member 230, the rotating wheel seat 200 and the rotating wheel 100 are in a locking state. At this time, the rotating wheel 100 can be rotated, and the side wall of the locking part 110 squeezes the locking bead 240 towards the assembly hole 220, so that the locking bead 240 leaves the locking hole 111 and enters the unlocking hole 112 to achieve the unlocking state. The depth of the locking hole 111 is greater than the depth of the assembly hole 220. The depth of the unlocking hole 112 is described. Furthermore, four locking holes 111 are provided, with two unlocking holes 112 between each pair of adjacent locking holes 111. This invention, through the combination of a rotating wheel 100, a rotating wheel seat 200, a locking part 110, an elastic element 230, and a locking bead 240, achieves a stable and controllable locking and unlocking mechanism. This structure provides a reliable locking function. When the locking bead 240 enters the locking hole 111 under the action of the elastic element 230, the rotating wheel 100 and the rotating wheel seat 200... The device forms a stable locking state, preventing the rotating wheel 100 from rotating unexpectedly due to external force or vibration, thus improving the safety and reliability of the device. This utility model provides a locking hole 111 on the side wall of the locking part 110 and provides an elastic element 230 and a locking bead 240 in the first assembly groove 210. This ensures that the locking bead 240 is not affected by the tightness of the connection between the rotating wheel 100 and the rotating wheel seat 200. Furthermore, the gasket of the rotating wheel 100 is eliminated, reducing production costs.

[0036] See Figures 1-7In this embodiment, the bottom of the first mounting groove 210 is provided with a first mounting hole 250 penetrating both ends of the wheel seat 200. A square shaft 300 is inserted into the first mounting hole 250. Further, the square shaft 300 includes a first shaft portion 310 and a second shaft portion 320. Both the first shaft portion 310 and the second shaft portion 320 are provided with flanges 330 on their outer peripheral sides. The first shaft portion 310 and the second shaft portion 320 are rotatably engaged in the first mounting through hole 440 through the flanges 330. Furthermore, the square shaft 300 enables the entire rotating mechanism to achieve precise torque transmission. The cross-sectional shape of the square shaft ensures a non-slip connection between the wheel 100 and the wheel seat 200, effectively preventing slippage or failure during rotation. The flanges 330 on the outer peripheral sides of the first shaft portion 310 and the second shaft portion 320 are used to ensure the stability of the shaft portion in the first mounting hole 250 through the engagement method, while allowing it to rotate.

[0037] See Figures 1-7 In this embodiment, the rotating wheel 100 has first countersunk holes 120 at its two opposite ends. One end of the first shaft 310 passes through the first countersunk holes 120. The end of the first shaft 310 passing through the first countersunk holes 120 has an internal threaded hole 311. A screw 290 can pass through the first countersunk holes 120 and be threaded into the internal threaded hole 311. Furthermore, by providing first countersunk holes 120 at the two opposite ends of the rotating wheel 100 and an internal threaded hole 311 at one end of the first shaft 310, the screw 290 can pass through the first countersunk holes 120 and be threaded into the internal threaded hole 311. This achieves a stable and convenient connection between the rotating wheel 100 and the first shaft 310. The design of the countersunk holes 440 optimizes the installation method, allowing the head of the screw 290 to be embedded in the holes 440 and flush with the surface of the rotating wheel 100. This not only improves the aesthetics of the device but also avoids interference problems caused by the protruding screw 290.

[0038] See Figures 1-7In this embodiment, the end of the wheel seat 200 near the wheel 100 is provided with a insertion groove 260 and a second mounting groove 270 communicating with the mounting hole 220. A damping plate 271 is provided in the second mounting groove 270. One side of the damping plate 271 is provided with a insertion post 272 for insertion into the insertion groove 260 for connection. The damping plate 271 is used to cover one side of the mounting hole 220 and contacts one side of the wheel 100. The damping plate is made of plastic. Furthermore, through the contact between the damping plate 271 and the wheel 100, a certain frictional resistance can be formed during the rotation of the wheel 100, thereby preventing the wheel 100 from rotating due to inertia or... The external force causes rapid rotation, improving the smoothness of rotation, making the operation more precise, and enhancing the user experience. Furthermore, the damping plate 271 effectively reduces noise and wear. The plastic material has good elasticity and cushioning properties, reducing direct friction between the rotating wheel 100 and other components during rotation, reducing wear on metal parts, and thus extending the device's service life. Simultaneously, the damping plate 271 also acts as a shield for the mounting hole 220, preventing the locking bead 240 from dislodging from it. The mounting hole 220 has sound-through holes on its sidewall that are not covered by the damping plate 271, allowing the sound of the locking bead colliding with the locking hole and unlocking hole to be released when the rotating wheel and its seat rotate relative to each other.

[0039] See Figures 1-7 In this embodiment, the rotating wheel seat 200 is provided with two second countersunk through holes 280 extending through its opposite ends. These second countersunk through holes 280 are arranged opposite each other on both sides of the rotating wheel seat 200. Threaded posts 281 for connecting with profiles are inserted into the second countersunk through holes 280. By fixing the rotating wheel seat 200 to the profiles using the threaded posts 281, the rotating wheel seat 200 can be stably installed on doors, windows, or other structures, ensuring that the entire device is not easily loosened or displaced during use, thus improving structural stability and durability. The symmetrical distribution of the second countersunk through holes 280 makes the force on the device more even during installation, reducing deformation or loosening caused by uneven force on one side, thereby improving the long-term stability and impact resistance of the device. Furthermore, the use of threaded posts 281 for fixing facilitates disassembly and assembly. When it is necessary to replace components or perform maintenance, the threaded posts 281 can be directly disassembled without damaging the entire device structure, improving the convenience and cost-effectiveness of maintenance.

[0040] See Figures 1-7In this embodiment, a square protrusion 312 is provided at one end of the first shaft portion 310 near the second shaft portion 320, and a square groove 321 adapted to the square protrusion 312 is provided at one end of the second shaft portion 320 near the first shaft portion 310. The cooperation of the square protrusion 312 and the square groove 321 restricts the axial rotation of the first shaft portion 310 and the second shaft portion 320. Furthermore, the precise engagement of the square protrusion 312 and the square groove 321 ensures that the first shaft portion 310 and the second shaft portion 320 can move synchronously during rotation, avoiding relative slippage and improving the mechanical efficiency and reliability of the device. Compared with the traditional circular shaft fit, the square structure can better resist the relative slippage that may occur during rotation, making the shaft connection more stable and improving the stability of the device. This structure can achieve fixation in the rotation direction without additional fasteners or pins, reducing assembly difficulty and maintenance costs.

[0041] See Figures 1-7 In this embodiment, the cross-section of the straight portion of the first countersunk hole 120 is one of a square, a regular hexagon, or a regular octagon. The cross-section of the end of the second shaft portion 320 near the rotating wheel 100 is adapted to the hole shape of the straight portion of the first countersunk hole 120, and is one of a square, a regular hexagon, or a regular octagon. Through the polygonal matching design, a better mechanical fit is formed between the second shaft portion 320 and the countersunk hole 440, avoiding slippage or rotation failure due to excessive rotational torque. Compared with the traditional circular hole fit, this design can significantly improve rotational stability and efficiency.

[0042] See Figures 1-7 In this embodiment, a handle is included, comprising a handle body 410 and a handle head 420. The handle head 420 has a cavity 430 for engaging the rotating wheel 100. A through hole 440 communicating with the cavity 430 is provided on the side wall of the handle head 420. A limiting post 450 is provided in the through hole 440. A limiting hole 460 is provided on the side wall of the rotating wheel 100 for the limiting post 450 to connect with the rotating wheel 100 for limiting. Furthermore, the cooperation between the limiting post 450 and the limiting hole 460 ensures that the handle will not loosen or deviate after installation, thereby ensuring accurate rotation angle of the handle during operation and avoiding the impact of rotational deviation on the use effect. The engaging design of the cavity 430 allows the handle to be quickly aligned with the rotating wheel 100 for efficient installation, while the additional fixing function of the limiting post 450 ensures that the handle will not loosen or shift due to long-term use, improving overall durability.
