[0031] In the related art, electrical appliances on the market with external wiring harnesses usually have a wire guard at the wiring harness interface of the electrical appliance to enhance the bending strength of the wiring harness and prevent the wiring harness from breaking and being damaged after frequent shaking or bending. The wire guard is generally made of flexible materials such as rubber and silicone or materials with higher hardness such as plastic. Existing wire guards generally use wire guards made of one of these materials. However, wire guards made of flexible materials such as rubber and silicone have a short bending life and are not conducive to long-term use. Wire guards made of hard plastic materials such as plastic have a matching gap with the shell when assembled to the interface, which is not conducive to waterproofing.

[0032] Based on the above questions and ideas, please combine Figures 1 to 6As shown, the utility model proposes a treatment handle 100, which includes a shell component 1 and a sheath component 2.

The hard rubber sleeve 21 is inserted into the through hole 14 and forms a connection for the soft rubber sleeve. The soft rubber sleeve 22 is provided with a through hole 212, and the soft rubber sleeve 22 is provided with a wire passage 226 for the wire harness 3 to pass through. The wire harness 3 is passed through the wire passage 226 and is electrically connected to the electronic components 4 in the installation cavity 13, wherein the soft rubber sleeve 22 covers at least part of the hard rubber sleeve 21, and the covered part of the soft rubber sleeve 22 is in close contact with the shell component 1 to ensure the waterproof effect between the shell component 1 and the sheath component 2, and to prevent moisture from entering the installation cavity 13 from the gap between the shell component 1 and the sheath component 2, causing damage to the electronic components 4 arranged in the installation cavity 13. The wire harness 3 extending from the through hole 14 is doubly protected by the soft rubber sleeve 22 and the hard rubber sleeve 21, which ensures its strength in a bending state and prolongs the service life of the sheath component 2.

[0043] In one embodiment of the present invention, Figures 2 to 5 As shown, the soft rubber sleeve 22 further includes a mounting portion 223 , which is connected to a side of the waterproof portion 222 facing away from the main body 221 , and is connected to the housing assembly 1 .

[0044] In this embodiment, the mounting portion 223 is connected to the waterproof portion 222 and is used to connect the shell assembly 1 to relatively fix the position of the soft rubber sleeve 22 to prevent the soft rubber sleeve 22 from slipping or moving along the through hole 14 after the treatment handle 100 is assembled, thereby affecting the bending of the wiring harness 3 and the waterproof effect between the sheath assembly 2 and the shell assembly 1, and at the same time facilitating the positioning and installation of the soft rubber sleeve 22.

[0045] In actual implementation, the mounting portion 223 can be connected to the shell assembly 1 by a detachable fitting method such as a plug-in structure and a locking structure. It can be understood that the mounting portion 223 is arranged in the mounting cavity 13 and is fitted and connected with the inner wall of the mounting cavity 13 to fix the installation position of the soft rubber sleeve 22.

[0047] In this embodiment, the mounting portion 223 and the shell assembly 1 are correspondingly provided with a connecting hole 15 and a mounting hole 225. When the soft rubber sleeve 22 is installed, the mounting hole 225 and the connecting hole 15 are coaxially arranged, and the inner wall of the connecting hole 15 can be provided with a thread. A screw is passed through the mounting hole 225 and screwed into the connecting hole 15, thereby realizing a detachable connection between the soft rubber sleeve 22 and the shell assembly 1.

[0048] In actual implementation, a connecting column is provided on the inner wall of the installation cavity 13, and the connecting column encloses a connecting hole 15 connected to the installation cavity 13. When the soft rubber sleeve 22 and the shell assembly 1 are connected, the installation portion 223 is abutted against the connecting column, thereby ensuring the stability of the installation portion 223 and the shell assembly 1 when connected.

[0049] In one embodiment of the present invention, Figure 2 and Figure 6As shown, a limiting groove 16 is provided on the inner wall of the through hole 14 , and a limiting protrusion 211 is provided on the hard rubber sleeve 21 corresponding to the limiting groove 16 , and the limiting protrusion 211 is limited in the limiting groove 16 .

[0050] In this embodiment, the hard rubber sleeve 21 is limited in the axial direction of the through hole 14 by the limiting cooperation between the limiting protrusion 211 and the limiting groove 16, so as to prevent the hard rubber sleeve 21 from moving or sliding along the through hole 14 after the treatment handle 100 is assembled, and at the same time facilitate the positioning and installation of the hard rubber sleeve 21.

[0051] In actual implementation, the limiting protrusion 211 can be arranged around the circumference of the hard rubber sleeve 21, and the limiting groove 16 is arranged corresponding to the limiting protrusion 211. The limiting groove 16 can be arranged in the middle section or edge position of the through hole 14, which is not specifically limited here. When one end of the hard rubber sleeve 21 is inserted into the waterproof groove 224, the limiting protrusion 211 also abuts against the end surface of the waterproof part 222, so as to judge whether the hard rubber sleeve 21 is inserted into place.

[0052] In one embodiment of the present invention, Figure 2 , Figure 4 and Figure 6 As shown, the cross-sectional area of ​​the through hole 212 gradually decreases from one end close to the installation cavity 13 to the end away from the installation cavity 13; and / or, the cross-sectional area of ​​the wire passage 226 gradually decreases from one end close to the installation cavity 13 to the end away from the installation cavity 13.

[0053] In the present embodiment, the through hole 212 is arranged in a trumpet-shaped variable cross-section, and the cross-sectional area gradually decreases from the end close to the installation cavity 13 to the end away from the installation cavity 13, that is, the cross-sectional area of ​​the through hole 212 at the end close to the installation cavity 13 is large, and the cross-sectional area of ​​the end away from the installation cavity 13 is small; similarly, the wire passage 226 is also arranged in a trumpet-shaped variable cross-section, and the cross-sectional area gradually decreases from the end close to the installation cavity 13 to the end away from the installation, that is, the cross-sectional area of ​​the end of the wire passage 226 close to the installation cavity 13 is large, and the cross-sectional area of ​​the end away from the installation cavity 13 is small; when assembling the treatment handle 100, the wiring harness 3 can be in the soft rubber sleeve. 22 is elastically deformed, and then the soft rubber sleeve 22 is inserted into the wire passing channel 226 from the end with a larger cross-sectional area of ​​the soft rubber sleeve 22. After that, the soft rubber sleeve 22 is inserted into the penetration hole 212 from the end with a larger cross-sectional area of ​​the penetration hole 212. After the wiring harness 3, the soft rubber sleeve 22 and the hard rubber sleeve 21 are assembled, the soft rubber sleeve 22 is limited between the wiring harness 3 and the hard rubber sleeve 21. If the wiring harness 3 is pulled out from the end of the wire passing channel 226 away from the installation cavity 13, the hard rubber sleeve 21 will limit the elastic deformation of the soft rubber sleeve 22, which greatly increases the resistance of the wiring harness 3 when it is pulled out. When the treatment handle 100 is assembled, the wiring harness 3 is not easy to loosen outward.

[0054] In actual implementation, the penetration hole 212 and the wire passage 226 are arranged in a trumpet shape, which can prevent the soft rubber sleeve 22 and the wiring harness 3 from being accidentally pulled out, and at the same time can increase the sealing between the wiring harness 3 and the soft rubber sleeve 22 and between the soft rubber sleeve 22 and the hard rubber sleeve 21, thereby ensuring the waterproof effect between the wiring harness 3 and the soft rubber sleeve 22 and between the soft rubber sleeve 22 and the hard rubber sleeve 21.

When installing the treatment handle 100, the assembled sheath assembly 2 and the wiring harness 3 can be placed at the position of the second housing 12 corresponding to the through hole 14, and then the first housing 11 and the second housing 12 are assembled and connected accordingly, so that the sheath assembly 2 is arranged in the through hole 14, thereby reducing the difficulty of installing the sheath assembly 2 and improving the convenience of the assembly and installation of the sheath assembly 2 and the housing assembly 1.

[0057] In actual implementation, the first shell 11 and the second shell 12 are respectively an upper shell and a lower shell or a left shell and a right shell, which are not specifically limited here. When the first shell 11 and the second shell 12 are combined, the inner surfaces of the first shell 11 and the second shell 12 are tightly fitted with the waterproof part 222 of the soft rubber cover 22, and finally the hard rubber cover 21 and the soft rubber cover 22 are waterproof as a whole.

[0058] Optionally, a first connecting column is provided on the inner wall of the first shell 11, and the first connecting column encloses a first connecting hole connecting the outside and the installation cavity 13. A second connecting column is provided on the inner wall of the second shell 12, and the second connecting column encloses a second connecting hole connecting the installation cavity 13.
