[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] The present invention will now be further described with reference to the accompanying drawings.

[0016] This utility model provides the following technical solution: As attached Figure 1-3 As shown, this utility model discloses a novel handle structure, including a handle sleeve 1, a handle 2, and a handle base 3. A groove 4 is formed within the handle sleeve 1. The handle base 3 is disposed within the groove 4 and connected to the handle sleeve 1. The handle 2 is connected to one end of the handle sleeve 1. A seat positioning structure protrudes from the inner wall of the groove 4, comprising a handle base positioning end 5 and a handle sleeve reinforcing block 6. The handle positioning end is located at the center of the groove wall of the groove 4 near the handle 2. A through groove 7 is formed on the handle positioning end. The handle sleeve reinforcing block 6 is disposed on one side of the handle base positioning end 5 and connected to the positioning end of the handle sleeve 1 and the inner wall of the groove 4. Specifically, in this design, by setting a seat positioning structure within the groove 4, precise positioning and stable connection of the handle base 3 within the handle sleeve 1 are achieved. The design of the handle base positioning end 5, especially the through groove 7, facilitates the subsequent installation of transmission components and ensures smooth and stable rotation of the handle. The addition of the handle glove reinforcement block 6 further enhances the connection strength between the handle glove 1 and the seat positioning structure, improving the durability and reliability of the entire handle structure.

[0017] Furthermore, the handle seat positioning end 5 has a square shaft positioning connection part 8 and a seat body connection part 9. The through groove 7 is formed in the square shaft positioning connection part 8 and extends to the seat body connection part 9. A through hole is formed on the inner wall of the square shaft positioning connection part 8 away from the seat body connection part 9, connecting the through groove 7 and the outside of the handle sleeve 1. The part of the outer wall of the handle sleeve 1 near the edge of the through hole is recessed to form a handle mounting groove 10. The handle 2 extends into the handle mounting groove 10 and connects with the handle sleeve 1. Specifically, in this embodiment, the through hole design allows the square shaft to pass smoothly through and extend to the outside of the handle sleeve 1, facilitating quick and accurate docking and installation with external transmission components (such as door lock square shafts). At the same time, the recessed structure of the handle mounting groove 10 provides stable support and limiting space for the end of the handle 2. The end of the handle 2 is fixed in the handle mounting groove 10 by screws or riveting, ensuring a firm and non-rotatable connection between the handle 2 and the handle sleeve 1. The recessed design of the handle mounting groove 10 not only enables the embedded installation of the handle 2, making the appearance more flat and beautiful, but also the close fit between the groove wall and the end contour of the handle 2 effectively distributes the torque on the handle 2 to the reinforcing block area of ​​the handle sleeve 1, significantly improving the torsional strength and long-term reliability of the connection between the handle 2 and the handle sleeve 1.

[0018] Furthermore, the handle glove 1, the handle seat positioning end 5, and the handle glove reinforcing block 6 are integrally formed by injection molding. A positioning opening 11 is formed on the edge of the handle glove 1 near the handle seat 3, corresponding to the position of the handle glove reinforcing block 6. Specifically, in this embodiment, the positioning opening 11 serves as a positioning reference for the mold during injection molding, ensuring precise and controllable geometric positions of the handle seat positioning end 5 and the reinforcing block. The integral molding process eliminates the gaps between parts in traditional assembly, resulting in a more uniform stress distribution and effectively preventing loosening and deformation of the connection parts due to long-term use. Simultaneously, the inverted conical structure of the positioning opening 11 provides a self-guiding effect during the assembly of the handle seat 3. When the handle seat 3 is pressed axially into the sleeve groove 4, the boss at its bottom contacts the inclined surface of the inner wall of the positioning opening 11, generating a radial force that automatically corrects the deviation between the central axis of the handle seat 3 and the sleeve groove 4, until the boss is fully embedded in the bottom of the positioning opening 11, achieving circumferential positioning.

[0019] Furthermore, the grip reinforcement block 6 smoothly transitions with the grip seat positioning end 5 and the inner wall of the grip 1. Specifically, in this embodiment, the connection between the reinforcement block and the positioning end and inner wall is designed as a smooth curved transition or a chamfered structure. This effectively reduces stress concentration by eliminating sharp edges, preventing cracks or fatigue fractures during repeated grip rotation. Simultaneously, the smooth transition optimizes material flow during injection molding, allowing molten plastic to uniformly fill the mold cavity, reducing defects such as bubbles and shrinkage marks, and ensuring the consistency of the overall structural strength of the grip 1.

[0020] Furthermore, the handle mounting slot 10 consists of two intersecting square slots, including a forward square slot 12 and an inclined square slot 13. The forward square slot 12 and the inclined square slot 13 are concentric, and both the inclined square slot 13 and the forward square slot 12 have corresponding upper edges. The upper edge of the inclined square slot 13 and the upper edge of the forward square slot 12 form an angle α. Specifically, in this embodiment, by setting the handle mounting slot 10 as two intersecting square slot structures, this structure allows for angle adjustment and reinstallation after the handle 2 is removed, adapting to diverse needs for handle operation angles in different scenarios. The concentricity of the forward square slot 12 and the inclined square slot 13 ensures that the handle 2 can be accurately reinstalled after angle adjustment, ensuring the stable operation of the overall handle function. The angle α formed between the upper edge of the inclined square slot 13 and the upper edge of the forward square slot 12 provides a clear range and reference for angle adjustment, making angle adjustment more precise and controllable. In practical applications, users can easily adjust the handle 2 to a suitable angle according to their own usage habits or specific usage scenarios, greatly improving the convenience and comfort of use. At the same time, this unique mounting slot design also increases the flexibility and adaptability of the handle structure, enabling it to better meet the usage requirements of different users and in different environments.

[0021] Furthermore, the included angle α is 150°. In this embodiment, the included angle α is set to 150°, which ensures that the handle 2 has sufficient adjustment space when adjusting the angle to meet the hand operation habits of different users and the usage needs in different scenarios.

[0022] Furthermore, several flanges 14 protrude from the inner wall of the handle sleeve 1 near the handle seat 3, flush with the end face of the handle sleeve reinforcing block 6 near the handle seat 3. The end face of the handle seat 3 abuts against the flanges 14. Specifically, in this embodiment, the design of the flanges 14 further enhances the connection stability between the handle seat 3 and the handle sleeve 1. When the handle seat 3 is assembled into the handle sleeve 1, one end face can tightly abut against the flanges 14, forming a reliable axial limit and preventing axial movement of the handle seat 3 during use. At the same time, the flanges 14 are flush with the end face of the handle sleeve reinforcing block 6 near the handle seat 3. This design not only optimizes the structural layout, making the overall structure more compact, but also ensures the uniformity of stress transmission. When the handle rotates, the force can be effectively distributed to a larger area of ​​the handle sleeve 1 through the flanges 14 and the reinforcing block, reducing local stress concentration and thus improving the load-bearing capacity and service life of the entire handle structure. In addition, the flange 14 provides additional guidance for the installation of the handle 3, making the assembly process simpler and faster, and improving production efficiency.

[0023] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
