[0027] As will be fully understood by those skilled in the art, the features of the different embodiments of this disclosure may be coupled or combined with each other in part or in whole, and may cooperate with each other and be technically driven in various ways. The embodiments of this disclosure may be implemented independently of each other, or may be implemented together in an interdependent relationship.

[0028] Reference Figures 1 to 4 This utility model discloses a combined handle structure, including a handle 1 and a handle head 2, wherein the handle 1 and the handle head 2 are fixedly connected as one unit.

[0029] Both the handle 1 and the handle head 2 of this handle are made of metal and are formed by casting. This breaks down the complex overall structure into two relatively simple parts, thereby reducing the casting difficulty and saving materials. Moreover, the handle 1 is universal, and different shapes of handle heads 2 can be matched according to customer needs, thus adapting to different customer requirements.

[0030] In this application, the handle 1 and the handle head 2 are tightly fitted together by stamping. Specifically, the handle 1 is provided with a plug end 3, and the handle head 2 is provided with a plug interface 4. The plug end 3 can be inserted into the plug interface 4 and tightly fitted and fixed to the plug interface 4. Because the tight fit is a large interference fit, it is necessary to use a stamping device to press the plug end 3 into the plug interface 4 so as to fix it firmly.

[0031] As shown in the figure, as a further structure of this application, the end wall of the plug-in end 3 is provided with a positioning groove 5, and the inner wall of the plug-in interface 4 is provided with a positioning protrusion 6 that can be inserted into the positioning groove 5. The positioning groove 5 is a rectangular groove and is integrally formed with the handle 1. Of course, the positioning protrusion 6 is also a rectangular strip of the corresponding shape and is integrally formed with the handle head 2. The positioning groove 5 and the positioning protrusion 6 are not only used to position the relative positions of the handle 1 and the handle head 2 during assembly, but also can prevent the handle 1 and the handle head 2 from loosening due to relative rotation after assembly.

[0032] As a preferred structure, the end wall of the plug-in end 3 is provided with a fastening protrusion 7 protruding from the outer surface of the end wall. The fastening protrusion 7 is evenly distributed in a ring on the outer surface of the end wall of the plug-in end 3. The inner wall of the plug-in interface 4 contacts and presses against the fastening protrusion 7 to achieve a tight fit. Of course, the end of the fastening protrusion 7 has a guiding bevel 8 to facilitate the fastening protrusion 7 to be inserted into the plug-in interface 4. The above structure facilitates assembly. The fastening protrusion 7 reduces the contact area between the end wall of the plug-in end 3 and the inner surface of the plug-in interface 4, thereby avoiding large friction during the tight fit and reducing the difficulty of assembly. Moreover, the even distribution of the fastening protrusion 7 in a ring can achieve uniform pressure between the plug-in end 3 and the plug-in interface 4. As a further preferred structure, the inner wall of the plug-in interface 4 is provided with an annular pressure strip. The annular pressure strip contacts and presses against the fastening protrusion 7 to achieve a tight fit. The annular pressure strip reduces the contact area between the fastening protrusion 7 and the inner wall of the plug-in interface 4, further reducing the difficulty of assembly.

[0033] As shown in the figure, the handle 1 is provided with an annular protrusion 9. After the plug end 3 is inserted into the plug interface 4, the annular protrusion 9 can abut against the end face of the handle head 2. The positioning of the annular protrusion 9 facilitates the assembly of the handle 1 and the handle head 2. Moreover, the outer edge of the annular protrusion 9 is flush with the outer edge of the end of the handle head 2, which improves the aesthetics.

[0034] As shown in the figure, the handle 1 includes a circular tube section 10, a circular ring section, and an arc-shaped transition section 11 connecting the circular tube section 10 and the circular ring section. The circular ring section forms a plug-in end 3. The circular tube section 10 is fixedly connected to the lock. The diameter of the circular ring section is larger than the diameter of the circular tube section 10.

[0035] As shown in the figure, the top surface and the annular side surface of the handle head 2 are both convex arc surfaces, and the bottom surface of the handle head 2 is flat. The insertion interface 4 is connected to the bottom surface. The whole structure is shaped like a mushroom, which is round and beautiful. Moreover, the annular side surface is evenly distributed with concave marks 12. One end of the concave mark 12 is connected to the top surface, and the other end of the concave mark 12 is connected to the bottom surface. The top surface is also arranged with semi-circular protrusions. The whole structure is shaped like a pumpkin, which is not only beautiful, but also gives customers a variety of choices and improves competitiveness.

[0036] The advantages of this structure compared to a solid metal handle are as follows:

[0037] 1. It can process workpieces of any wall thickness and saves materials;

[0038] 2. Practical devices such as locks, knobs, and clips can be placed anywhere within the sphere's interior space.

[0039] 3. The screw connection components have a smoother and more aesthetically pleasing appearance;

[0040] 4. Suitable for products and internal component structures that do not require strong vertical drag or traction.

[0041] 5. This structure is suitable for situations where the space inside the product is too small and small components are necessary to achieve the function, but screw connections cannot be used to maximize the advantages of the product. This fills the gaps in the usual component connection methods and improves the efficiency of product assembly.

[0042] The above provides a detailed description of a combined handle structure provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
