Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] It should also be understood that the terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” are intended to include the plural forms unless the context clearly indicates otherwise.

[0033] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0034] Combination Figures 1 to 5 As shown, this utility model embodiment provides a handle for use on door and window profiles, including a handle 10 and a base assembly 20. The base assembly 20 includes a rotating wheel 21 and a base 22. The rotating wheel 21 includes a rotating part 211 and a connecting part 212 arranged opposite to each other. The connecting part 212 is connected to the handle 10. The base 22 has a stepped hole 221. The stepped surface 2211 of the stepped hole 221 faces one end of the base 22. The rotating part 211 extends from the other end of the base 22 into the stepped hole 221. The end of the rotating part 211 is provided with a riveting part 2111. The riveting part 2111 is rotatably connected to the stepped surface 2211 of the stepped hole 221.

[0035] In this embodiment, the rotating wheel 21 includes a rotating part 211 and a connecting part 212 disposed opposite to each other. The connecting part 212 is used to connect with the handle 10. The head of the handle 10 is provided with a mounting groove 11. The connecting part 212 of the rotating wheel 21 can be disposed within the mounting groove 11 of the handle 10 (the shapes of the mounting groove 11 and the connecting part 212 can be rectangular). After the mounting groove 11 and the connecting part 212 are connected, they are then fixed by a connector 12. See the attached document for details. Figure 3 As shown, this enables the handle 10 to drive the rotating wheel 21 to rotate.

[0036] Furthermore, the base 22 has a stepped hole 221, with openings at both ends and a stepped surface 2211 along the axial direction of the stepped hole 221. The stepped surface 2211 of the stepped hole 221 faces one end of the base 22, providing support for positioning and rotational connection of the rotating part 211 of the wheel 21. The rotating part 211 is inserted into the stepped hole 221 through the other end of the base 22, and then the end of the rotating part 211 is riveted using a special tool to form a riveted part 2111 at the end of the rotating part 211. The riveted part 2111 forms a rotational connection with the stepped surface 2211 of the stepped hole 221. The design of the riveted part 2111 ensures that the wheel 21 can rotate within the base 22, while avoiding the risk of the wheel 21 axially falling off. In actual use, the handle 10 is connected to the door and window profile through the base assembly 20. The rotating wheel 21 has a square hole in its center, which can accommodate an externally inserted square bar. When the handle 10 is operated, the rotating wheel 21 rotates, causing the square bar to rotate, thereby realizing the opening or closing of the door or window. Through the above design, the handle of this utility model has the advantages of fewer accessories, simple assembly, and low manufacturing cost.

[0037] In traditional handle designs, the base assembly is an essential component, primarily used to support the handle's rotation mechanism and connect the door and window profiles. However, the "baseless handle" in this embodiment, through structural innovation, eliminates this separate base assembly, integrating the support and fixing functions originally performed by the base into the optimized base assembly 20, thus creating a simplified design that does not require a separate base assembly. From an aesthetic perspective, the baseless handle, by eliminating the redundant parts of the traditional base assembly, has a more compact structure and integrates more naturally with the overall door and window profiles, meeting the demands of modern door and window products for efficient and convenient installation.

[0038] In one embodiment, the riveting part 2111 is turned outward and rests on the step surface 2211.

[0039] In this embodiment, the outward turning of the riveting part 2111 is completed by riveting the end of the rotating part 211 with a special tool after the rotating part 211 extends into the stepped hole 221 from the other end of the base 22. During the riveting process, the end of the rotating part 211 gradually expands and turns outward under the action of external force to form the riveting part 2111. The riveting part 2111 is finally attached to and mounted on the stepped surface 2211 of the stepped hole 221. This structural design can effectively fix the axial position of the rotating wheel 21 and prevent it from falling off, and also enable the rotating wheel 21 to rotate smoothly relative to the base 22.

[0040] Combination Figure 6 and Figure 7As shown, in one embodiment, the riveting part 2111 is turned outward, and the base assembly 20 also includes a gasket 23, which is clamped between the step surface 2211 and the riveting part 2111.

[0041] In this embodiment, the shim 23 is used to further optimize the rotational performance of the wheel 21. After the rotating part 211 of the wheel 21 is inserted through the stepped hole 221 of the base 22, the end of the wheel 21 is provided with a riveting part 2111. After the riveting part 2111 is outwardly turned, it is fixed in place with the stepped surface 2211 of the stepped hole 221 of the base 22. The shim 23 is disposed between the stepped surface 2211 and the riveting part 2111. During the riveting process, the riveting part 2111 indirectly contacts the stepped surface 2211 through the shim 23 after being outwardly turned. The shim 23 is made of a material with moderate elasticity, which can effectively absorb the small vibrations or stresses generated by the wheel 21 during rotation, thereby improving the smoothness of rotation. In addition, the main function of the shim 23 is to reduce the requirements for riveting accuracy in the riveting process to a certain extent, because the shim 23 can compensate for the minor dimensional errors between the riveting part 2111 and the stepped surface 2211, simplifying the production process and improving assembly efficiency. During use, the shim 23 provides a certain amount of buffering force in the axial direction. When the handle 10 drives the wheel 21 to rotate, the shim 23 effectively reduces the friction and wear between the riveting part 2111 and the step surface 2211, thereby extending the service life of the base assembly 20.

[0042] In one embodiment, the gasket 23 has axial elasticity.

[0043] In this embodiment, when the wheel 21 rotates within the base 22, the axial elasticity of the pad 23 absorbs the minor vibrations and impacts generated by the rotation, effectively reducing friction and wear. Furthermore, the axial elasticity of the pad 23 also has an important dimensional compensation function. During the riveting process, due to potential slight dimensional errors in the riveting process, the elastic deformation of the pad 23 can automatically adjust the contact state between the riveted part 2111 and the stepped surface 2211, ensuring that the riveted part 2111 always maintains appropriate fixing force. For example, when the handle 10 drives the wheel 21 to rotate at a large angle, the pad 23 can evenly distribute external forces through its elastic deformation, protecting the contact area between the base 22 and the wheel 21, and extending the service life of the handle.

[0044] In one embodiment, a receiving groove 2112 is provided on the outer side of the riveting part 2111, one side of the gasket 23 is received in the receiving groove 2112, and the other side of the gasket 23 is located on the step surface 2211.

[0045] In this embodiment, the receiving groove 2112 is formed by riveting the outer side of the riveted part 2111; that is, the receiving groove 2112 does not exist when the outer side of the riveted part 2111 is not processed. The size design of the receiving groove 2112 can accommodate a portion of the gasket 23, while providing axial and radial support for the gasket 23. The other side of the gasket 23 directly contacts the stepped surface 2211. Since the gasket 23 is simultaneously located between the receiving groove 2112 and the stepped surface 2211, the elastic properties of the gasket 23 provide effective cushioning during the rotation of the rotating part 211. In addition, the receiving groove 2112 also facilitates assembly. After the riveting operation is completed, the gasket 23 can be installed into the receiving groove 2112 by simple insertion and positioning, without the need for additional complex fixing measures.

[0046] In one embodiment, the rotating wheel 21 further includes a rotating wheel body 213 disposed between the rotating part 211 and the connecting part 212. The rotating wheel body 213 is located outside the stepped hole 221, which is a through hole.

[0047] In this embodiment, the design of the wheel body 213 not only serves to connect the rotating part 211 and the connecting part 212, but also effectively limits the position of the wheel 21 in the base 22, thereby improving the operational stability of the entire base assembly 20. The outer diameter of the wheel body 213 is larger than the diameter of the stepped hole 221 of the base 22, so the wheel body 213 is limited to the outside of the stepped hole 221. The stepped hole 221 is composed of two through holes of different diameters (a large through hole and a small through hole), forming a stepped surface 2211 between them. Before being inserted into the stepped hole 221, the rotating part 211 can be a cylindrical structure, so that it can be inserted into the stepped hole 221 through the small through hole. After being inserted into the stepped hole 221, the end of the rotating part 211 can be riveted, so that the riveted part 2111 and the stepped surface 2211 of the stepped hole 221 form a rotatable connection, while the wheel body 213 is limited to the outside of the small through hole of the stepped hole 221.

[0048] Furthermore, the wheel body 213 also serves to bear and distribute force. When the handle 10 drives the wheel 21 to rotate, the external force is transmitted to the wheel body 213 through the connecting part 212. The wheel body 213 distributes the force to the circumference of the base 22, thereby reducing local stress concentration and improving the durability of the entire base assembly 20. In addition, the outer surface of the wheel body 213 can be further optimized to a smooth surface or a lubricating coating can be applied to reduce friction during rotation and improve the smoothness of rotation.

[0049] In one embodiment, the rotating part 211 includes a rotating body 2113, and the riveting part 2111 is connected to the end of the rotating body 2113, which is a cylindrical structure.

[0050] In this embodiment, the cylindrical structure of the rotating body 2113 ensures that the rotating part 211 can rotate freely within the stepped hole 221 of the base 22, reducing friction and resistance caused by irregular shape. The cylindrical structure is easy to process and manufacture, and can be efficiently produced through traditional CNC turning or casting processes, improving production efficiency and reducing manufacturing costs. The cylindrical structure of the rotating body 2113 can form a precise fit with other components (such as the small through-hole of the stepped hole 221). For example, in this embodiment, the gasket 23 is arranged around the rotating body 2113, utilizing its axial elasticity to provide additional cushioning and support, thereby further improving rotational performance and durability.

[0051] Combination Figures 8 to 10 As shown, in one embodiment, the base assembly 20 further includes a plurality of positioning components 24. The positioning components 24 include positioning elements 241 (such as steel balls) and elastic elements 242 (such as springs). The base 22 has a plurality of mounting holes 222 corresponding to the plurality of positioning components 24, and the plurality of mounting holes 222 are arranged around the stepped hole 221. The positioning elements 241 and the elastic elements 242 are both disposed in the mounting holes 222. The elastic elements 242 hold the positioning elements 241 against the side facing the rotating wheel 21. The rotating wheel 21 has a plurality of positioning holes 214 corresponding to the positioning elements 241.

[0052] In this embodiment, the base 22 has several mounting holes 222 (four mounting holes 222 in this embodiment) for mounting the positioning component 24. The mounting holes 222 are evenly distributed around the stepped hole 221, and each mounting hole 222 contains a positioning element 241 and an elastic element 242. The positioning element 241 cooperates with the rotating wheel 21 to achieve the positioning function, while the elastic element 242 provides elastic support for the positioning element 241. The positioning element 241 and the elastic element 242 are assembled in the following manner: the elastic element 242 is located at the bottom of the mounting hole 222, and the positioning element 241 is held by the elastic element 242 and partially extends out of the mounting hole 222, facing the end face of the rotating wheel 21. This design allows the positioning element 241 to be in a preloaded state and to move flexibly under the action of the elastic element 242.

[0053] Furthermore, the rotating wheel 21 has several positioning holes 214 (four positioning holes 214 in this embodiment) corresponding to the positions of the positioning members 241. The number of positioning holes 214 is the same as that of the mounting holes 222, and they are evenly distributed circumferentially. When the rotating wheel 21 rotates around the stepped hole 221, the positioning member 241 comes into contact with the positioning hole 214 under the action of the elastic member 242. When the positioning member 241 is aligned with the positioning hole 214, the positioning member 241 is partially embedded in the positioning hole 214, thereby achieving precise positioning of the rotating wheel 21. When the handle 10 drives the rotating wheel 21 to rotate, the positioning member 241 slides and disengages from the current positioning hole 214 under the support of the elastic member 242; when the rotating wheel 21 rotates to a new predetermined position, the positioning member 241 is embedded in the corresponding positioning hole 214 under the elastic force of the elastic member 242, thus completing the next positioning.

[0054] Combination Figure 11 As shown, in one embodiment, the mounting hole 222 is a closed through hole, and the diameter of the end of the mounting hole 222 facing the rotating wheel 21 is smaller than the diameter of the end away from the rotating wheel 21. The end of the mounting hole 222 away from the rotating wheel 21 is provided with a limiting part 2221 for limiting the displacement of the elastic member 242.

[0055] In this embodiment, the mounting hole 222 has an axially tapering inner diameter, with the diameter at the end facing the rotating wheel 21 (small diameter end) being smaller than the diameter at the end away from the rotating wheel 21 (large diameter end), thus forming a "narrowing" structure. This narrowing through-hole design allows the positioning member 241 and the elastic member 242 to be effectively limited and guided within the mounting hole 222. The outer diameter of the positioning member 241 matches the smaller diameter at the end of the mounting hole 222 facing the rotating wheel 21. Therefore, under the action of the elastic member 242, the positioning member 241 can partially extend out of the mounting hole 222 without detaching from it and engage with the positioning hole 214 on the rotating wheel 21 to achieve positioning. The larger diameter at the end away from the rotating wheel 21 provides sufficient space for the assembly of the elastic member 242, allowing it to be easily inserted into the mounting hole 222.

[0056] To further limit the displacement of the elastic element 242, a limiting part 2221 is provided at the end of the mounting hole 222 away from the rotating wheel 21. The limiting part 2221 is formed by local machining at the large-diameter end of the mounting hole 222. Its function is to provide effective support for the elastic element 242 when it is subjected to external force, thereby preventing the elastic element 242 from detaching from the mounting hole 222 due to excessive force. The limiting part 2221 can be designed as a circumferentially flanged or boss structure, and its size and shape are adapted to the outer diameter of the elastic element 242 to ensure that the elastic element 242 maintains a stable axial position during operation. In this embodiment, each mounting hole 222 is provided with three limiting parts 2221, specifically as follows: Figure 11 As shown.

[0057] This utility model also provides a door and window profile, including the handle as described above.

[0058] In this embodiment, the handle is installed on the frame structure of the door and window profile, and the handle 10 of the handle is fixedly connected to the door and window profile through the base assembly 20. To further optimize the installation effect, holes or slots matching the handle can be pre-set on the door and window profile. The base assembly 20 of the handle can quickly connect with the door and window profile through these pre-set structures, making the installation process simple and convenient.

[0059] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
