Detailed Implementation

[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 handle structure for a sliding door, including handles 1 respectively disposed on both sides of the sliding door 4. Each handle 1 includes a handle body 2 and a handle base 3, both made of the same material. An installation groove 5 is formed on the sliding door 4, and one end of the handle base 3 extends into the installation groove 5 and connects to the sliding door 4. The handle body 2 is detachably mounted on the handle base 3. A handle positioning connection structure 6 is provided on the handle base 3, including a handle positioning groove 7 formed on the handle base 3 and a groove along the handle positioning groove 7. A handle positioning end 8 protrudes from the edge of the groove 7 onto the outer surface of the handle base 3. The handle positioning end 8 has a ring-shaped structure and a handle mounting inlet 9 communicating with the handle positioning groove 7. One end of the handle body 2 extends into and passes through the handle positioning groove 7 via the handle mounting inlet 9. The handle positioning end 8 limits the radial position of the handle body 2 within the handle positioning groove 7. An axial limiting part 10 is provided on the inner wall of the handle positioning groove 7, limiting the axial position of the handle body 2 within the handle positioning groove 7. Specifically, in this design, a precise and stable connection between the handle body 2 and the handle base 3 is achieved by setting a handle positioning connection structure 6 on the handle base 3. The handle positioning groove 7 provides initial positioning space for the handle body 2, while the ring-shaped structure of the handle positioning end 8, which protrudes along the edge of the handle positioning groove 7, further enhances the stability of the positioning. The design of the handle mounting inlet 9 allows the handle body 2 to easily extend into and pass through the handle positioning groove 7, facilitating installation and ensuring reliable connection. Simultaneously, the handle positioning end 8 effectively limits the radial position of the handle body 2 within the handle positioning groove 7, preventing radial displacement during use. Furthermore, the axial limiting part 10 provided on the inner wall of the handle positioning groove 7 precisely limits the axial position of the handle body 2 within the groove, ensuring its stable position in the axial direction.

[0017] Furthermore, the handle body 2 has a body portion 11 and a seat connecting portion 12. The seat connecting portion 12 protrudes from the side of the body portion 11 near the sliding door 4. The seat connecting portion 12 extends into the handle mounting inlet 9 and engages with the handle positioning end 8 for limiting. An axial limiting annular groove 13 is formed on the seat connecting portion 12. The axial limiting portion 10 extends into the axial limiting annular groove 13 and cooperates with the seat connecting portion 12 to limit the axial position of the handle body 2 on the handle seat 3. Specifically, in this embodiment, the handle body 2 achieves a tight fit with the handle seat 3 through the combination of the body portion 11 and the seat connecting portion 12. The seat connecting portion 12 protrudes from the side of the body portion 11 near the sliding door 4. This design allows the seat connecting portion 12 to smoothly extend into the handle mounting inlet 9 and engage with the handle positioning end 8 for limiting, thereby ensuring the stability of the handle body 2 in the radial direction. Meanwhile, the axial limiting groove 13 on the seat connection part 12 cooperates with the axial limiting part 10 on the inner wall of the handle positioning groove 7, further precisely limiting the position of the handle body 2 in the axial direction. This double limiting design not only improves the connection stability between the handle body 2 and the handle seat 3, but also makes the entire handle 1 structure more reliable and durable during use.

[0018] Furthermore, the axial limiting part 10 is a plurality of equally spaced protrusions forming on the inner wall of the handle positioning groove 7. The axial limiting part 10 has a trapezoidal end 14, which is located on the side of the axial limiting part 10 away from the side wall of the handle positioning groove 7. The trapezoidal end 14 has two inclined surfaces opposite to the inner wall of the axial limiting annular groove 13. Specifically, in this embodiment, the axial limiting part 10 adopts a plurality of equally spaced protrusions. This design ensures the stability of the limiting and facilitates manufacturing. The two inclined surfaces formed on the side of the trapezoidal end 14 away from the side wall of the handle positioning groove 7 form good contact with the inner wall of the axial limiting annular groove 13. When the handle body 2 is subjected to axial force, the inclined surfaces of the trapezoidal end 14 can play a guiding role, guiding the axial limiting annular groove 13 on the handle body 2 to move along a specific direction, making the fit between the axial limiting part 10 and the axial limiting annular groove 13 tighter and further enhancing the stability of the axial limiting. This design not only effectively prevents the handle body 2 from loosening in the axial direction, but also disperses and bears axial force to a certain extent, improving the load-bearing capacity of the entire handle 1 structure. Moreover, the evenly spaced protrusion structure ensures that the axial limiting part 10 is evenly distributed on the inner wall of the handle positioning groove 7, which can more evenly limit the axial position of the handle body 2, ensuring that the handle body 2 remains stable when subjected to axial forces in different directions, and preventing damage due to excessive local stress, thus greatly improving the service life and reliability of the handle 1 structure.

[0019] Furthermore, the inner diameter of the handle positioning groove 7 is larger than the inner diameter of the handle mounting inlet 9, and the handle positioning groove 7 and the handle mounting inlet 9 are coaxially arranged. Specifically, in this embodiment, the design that the inner diameter of the handle positioning groove 7 is larger than the inner diameter of the handle mounting inlet 9 provides a reasonable space transition for the installation of the handle body 2. The larger inner diameter of the handle positioning groove 7 ensures that the handle body 2 has enough space for position adjustment during initial positioning, allowing it to more accurately extend into the appropriate position. The relatively smaller handle mounting inlet 9 plays a precise guiding role, enabling the handle body 2 to smoothly and accurately enter the handle positioning groove 7 through the inlet. At the same time, the coaxial arrangement of the handle positioning groove 7 and the handle mounting inlet 9 ensures the linear movement trajectory of the handle body 2 during installation, avoiding installation difficulties or loose connections caused by misalignment. The coaxial arrangement also makes the handle body 2 more evenly stressed after installation, reducing stress concentration caused by uneven stress, thereby further improving the stability and durability of the handle 1 structure.

[0020] Furthermore, the handle base 3 has a connecting portion 15 that is adhered and fixed to the surface of the sliding door 4, and the connecting portion 15 protrudes along the edge of the handle base 3. Specifically, in this embodiment, the handle base 3 is adhered and fixed to the surface of the sliding door 4 through the connecting portion 15. This design enhances the stability of the connection between the handle base 3 and the sliding door 4. The connecting portion 15 protrudes along the edge of the handle base 3, which not only increases the contact area with the surface of the sliding door 4, making the adhesion more secure, but also facilitates positioning and adjustment during installation, ensuring that the handle base 3 can be accurately installed in the predetermined position on the sliding door 4. At the same time, compared with traditional screw fixing methods, this adhesive fixing method has the advantages of simple installation and beautiful appearance. It eliminates the need to drill holes in the sliding door 4, avoiding the problems of structural damage or reduced sealing of the sliding door 4 that may be caused by drilling.

[0021] Furthermore, the handles 1 on both sides of the sliding door 4 include an inner handle 16 and an outer handle 17. The inner handle 16 also has a grip portion 18, which is a strip-shaped structure disposed on the side of the outer handle 17 away from the sliding door 4. Specifically, in this embodiment, the grip portion 18 added to the inner handle 16 has a strip-shaped structure and is disposed on the side of the outer handle 17 away from the sliding door 4. This layout fully considers the user's operating habits for opening and closing the door.
