[0034] To make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Obviously, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present invention without making creative efforts belong to the scope of protection of the present invention.

[0035] This embodiment relates to a seatless door handle and a lock. Refer to Figures 1 - 7, including a runner 100 and a runner base 200. One end of the runner 100 is protrudingly provided with a clamping portion 110, and a plurality of clamping holes 111 and unlocking holes 112 are spaced around the circumferential side of the clamping portion 110; one end of the runner base 200 is recessed with a first assembly groove 210, and a plurality of assembly holes 220 are formed in the side wall of the first assembly groove 210. An elastic member 230 and a clamping bead 240 are arranged in the assembly hole 220. One end of the elastic member 230 acts on the bottom of the assembly hole 220, and the opposite end of the elastic member 230 acts on the clamping bead 240; when the clamping bead 240 enters the clamping hole 111 under the elastic force of the elastic member 230, the runner base 200 and the runner 100 are in a clamped state. At this time, the runner 100 can be rotated, and the side wall of the clamping portion 110 squeezes the clamping bead 240 toward one side of the assembly hole 220, so that the clamping bead 240 leaves the clamping hole 111 and enters the unlocking hole 112 to reach the unlocking state. The depth of the clamping hole 111 is greater than the depth of the unlocking hole 112. Further, four clamping holes 111 are provided, and two unlocking holes 112 are arranged between every two adjacent clamping holes 111 among the four clamping holes 111. Through the combination of the runner 100, the runner base 200, the clamping portion 110, the elastic member 230 and the clamping bead 240, the present invention realizes a stable and controllable locking and unlocking mechanism. This structure can provide a reliable locking function. When the clamping bead 240 enters the clamping hole 111 under the action of the elastic member 230, the runner 100 and the runner base 200 form a stable clamping state, preventing the runner 100 from rotating accidentally due to external force or vibration, and improving the use safety and reliability of the device; by providing the clamping holes 111 on the side wall of the clamping portion 110 and arranging the elastic member 230 and the clamping bead 240 in the first assembly groove 210, the present invention makes the clamping of the clamping bead 240 with the clamping hole 111 and the unlocking with the unlocking hole 112 not affected by the tightness of the connection between the runner 100 and the runner base 200. Further, the gasket of the runner 100 is cancelled, reducing the production cost.

[0036] Refer to Figures 1 - 7, in this embodiment, a first mounting hole 250 penetrating through opposite ends of the runner base 200 is formed at the bottom of the groove body of the first assembly groove 210. A square shaft member 300 is disposed in the first mounting hole 250. Further, the square shaft member 300 includes a first shaft portion 310 and a second shaft portion 320. Flanges 330 are provided on the outer peripheral sides of the first shaft portion 310 and the second shaft portion 320. The first shaft portion 310 and the second shaft portion 320 are rotationally clamped in the first mounting through hole 440 through the flanges 330. Further, through the square shaft member 300, the entire rotating mechanism can achieve precise torque transmission. The cross-sectional shape of the square shaft member ensures a non-sliding connection between the runner 100 and the runner base 200, effectively preventing slipping or failure during rotation. Moreover, flanges 330 are provided on the outer peripheral sides of both the first shaft portion 310 and the second shaft portion 320. The function of the flange 330 is to ensure the relatively stable state of the shaft portion in the first mounting hole 250 through the clamping method while allowing it to rotate.

[0037] Refer to Figures 1 - 7 , in this embodiment, first countersunk through holes 120 are provided at opposite ends of the runner 100. One end of the first shaft portion 310 is inserted into the first countersunk through hole 120. An internal threaded hole 311 is provided at the end of the first shaft portion 310 inserted into the first countersunk through hole 120. A screw 290 can pass through the first countersunk through hole 120 and be threadedly connected to the internal threaded hole 311. Further, by providing the first countersunk through holes 120 at opposite ends of the runner 100 and providing the internal threaded hole 311 at one end of the first shaft portion 310, the screw 290 can pass through the first countersunk through hole 120 and be threadedly connected to the internal threaded hole 311, realizing a firm and convenient connection between the runner 100 and the first shaft portion 310. The design of the countersunk through hole 440 optimizes the installation method, enabling the head of the screw 290 to be embedded in the through hole 440 and flush with the surface of the runner 100, which not only improves the aesthetics of the device but also avoids interference problems caused by the protrusion of the screw 290.

[0038] Refer to Figures 1 - 7In this embodiment, the end of the wheel seat 200 close to the wheel 100 is provided with a plug-in slot 260 and a second assembly slot 270 connected to the assembly hole 220, and a damping plate 271 is provided in the second assembly slot 270. A plug-in column 272 for inserting into the plug-in slot 260 for connection is provided on one side of the damping plate 271. The damping plate 271 is used to cover one side of the assembly hole 220 and contact 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 friction 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 excessive rotation, which improves the stability of rotation, makes the control more precise, and enhances the user experience; and the damping plate 271 can effectively reduce noise and wear, and the plastic material has good elasticity and buffering performance, which can reduce the direct friction between the wheel 100 and other components during rotation, reduce the wear of metal parts, and thus extend the service life of the device; at the same time, the damping plate 271 also plays a shielding role in the assembly hole 220, which can prevent the locking bead 240 from falling out of the assembly hole 220. The side wall of the assembly hole 220 is provided with a sound hole that is not covered by the damping plate 271. When the wheel and the wheel seat rotate relative to each other, the sound of the locking bead colliding with the locking hole and the unlocking hole can be released.

[0039] See also Figures 1 - 7 In this embodiment, the wheel seat 200 is provided with a second countersunk through hole 280 that passes through its opposite two ends. Two second countersunk through holes 280 are provided and are relatively arranged on both sides of the wheel seat 200. A threaded column 281 for connecting with the profile is inserted in the second countersunk through hole 280. The threaded column 281 is fixed to the profile, so that the wheel seat 200 can be firmly installed on doors, windows or other structures, ensuring that the entire device is not easy to loosen or shift during use, thereby improving the structural stability and durability; the symmetrical distribution of the second countersunk through holes 280 makes the device more evenly stressed during installation, which can reduce the deformation or loosening caused by uneven stress on one side, thereby improving the long-term stability and impact resistance of the device; and the threaded column 281 fixing method is convenient for disassembly and assembly. When components need to be replaced or repairs need to be carried out, the threaded column 281 can be directly removed without destroying the entire device structure, thereby improving the convenience and cost-effectiveness of maintenance.

[0040] See also Figures 1 - 7, in this embodiment, a square convex portion 312 is provided at one end of the first shaft portion 310 close to the second shaft portion 320, and a square groove 321 adapted to the square convex portion 312 is provided at one end of the second shaft portion 320 close to the first shaft portion 310. The axial rotation of the first shaft portion 310 and the second shaft portion 320 is restricted through the cooperation of the square convex portion 312 and the square groove 321. Further, through the precise fitting of the square convex portion 312 and the square groove 321, it is ensured that the first shaft portion 310 and the second shaft portion 320 can move synchronously during rotation, avoiding relative sliding, 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 slip that may occur during rotation, making the shaft system 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 the assembly difficulty and also lowering the maintenance cost.

[0041] Refer to Figures 1 - 7 , in this embodiment, the cross-section of the straight-through part of the first countersunk through-hole 120 is one of a square, a regular hexagon, and a regular octagon. The cross-section of one end of the second shaft portion 320 close to the runner 100 is adapted to the hole shape of the straight-through part of the first countersunk through-hole 120 and is one of a square, a regular hexagon, and a regular octagon. Through the matching design of polygons, a better mechanical fit is formed between the second shaft portion 320 and the countersunk through-hole 440, avoiding slipping or rotation failure due to excessive rotation torque. Compared with the traditional circular hole fit, this design can significantly improve the rotation stability and efficiency.

[0042] Refer to Figures 1 - 7 , in this embodiment, it includes a handle. The handle includes a handle body 410 and a handle head 420. A cavity 430 for engaging with the runner 100 is provided inside the handle head 420. 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 inside the through-hole 440. A limiting hole 460 for connecting the limiting post 450 and the runner 100 for limiting is provided on the side wall of the runner 100. Further, the cooperation of the limiting post 450 and the limiting hole 460 ensures that the handle will not become loose or have a rotational deviation after installation, thereby ensuring the accurate rotation angle of the handle during operation and avoiding affecting the use effect due to rotational deviation. The engaging design of the cavity 430 enables the handle to quickly align with the runner 100, realizing efficient installation, and the additional fixing effect of the limiting post 450 ensures that the handle will not become loose or displaced due to long-term use, improving the overall durability.
