Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0030] refer to Figures 1 to 6 ,like Figure 1 , Figure 2 and Figure 3As shown, this embodiment provides a dustproof terminal box for a roller shutter door motor. Its ingenious design provides excellent dustproof performance. The terminal box includes a base 1, a box body 2, a cover 3, and a dustproof sealing ring 5. All components work together to ensure stable operation of the terminal box even in harsh environments. The base 1 is fixed to the side wall of the roller shutter door motor 100 by screws evenly distributed around its perimeter, providing solid support for the entire terminal box. The box body 2 is mounted on the base 1, and its top is surrounded by a boss 21 with an annular first sealing groove 212. The cover 3 is installed at the opening of the box body 2 by screws 4. An outer edge 32 is provided around the side of the cover 3, protruding from the cover 3 to increase the contact area between the cover 3 and the box body 2, improving the dustproof sealing effect. A dustproof sealing ring 5 is provided between the box body 2 and the cover 3. The dustproof sealing ring 5 includes an integral main frame 51, a first sealing component, a second sealing component, and a sealing gasket 56. The first and second sealing components are located below the main frame 51 and are respectively composed of a first sealing arm 52, a second sealing arm 53, a first sealing lip 54, and a second sealing lip 55, forming a multi-layer sealing barrier to effectively prevent dust intrusion. The first sealing component is located to the left of the second sealing component, and the sealing gasket 56 is located to the right of the second sealing component. The sealing gasket 56 has through holes 561 around its perimeter for screws 4 to pass through, which ensures both sealing performance and ease of installation.

[0031] like Figure 2 As shown, the bottom area of ​​the cover 3 is larger than the top area, which allows the cover 3 to better cover the box 2 during installation, further enhancing the sealing effect. The bottom of the cover 3 has mounting parts 31 around its perimeter, and the mounting parts 31 have mounting holes for screws 4 to pass through, making it easy to firmly fix the cover 3 to the box 2.

[0032] Specifically, such as Figure 5 As shown, the bottom of the mounting part 31 has an annular second sealing groove 311, and the top of the main frame 51 is fixed in the second sealing groove 311, making the connection between the dustproof sealing ring 5 and the cover 3 tighter and further improving the dustproof performance.

[0033] During installation, the top of the main frame 51 of the dustproof sealing ring 5 is securely embedded in the annular second sealing groove 311 of the bottom mounting part 31 of the cover 3, making the connection between the dustproof sealing ring 5 and the cover 3 tighter and further improving the dustproof performance. When the cover 3 is tightly connected to the box 2 by the screws 4, the dustproof sealing ring 5 is compressed, and the first sealing arm 52, the second sealing arm 53, the first sealing lip 54, and the second sealing lip 55 all undergo elastic deformation, tightly fitting against the surface of the first sealing groove 212 of the protrusion part 21 of the box 2, forming a solid sealing barrier.

[0034] The dustproof sealing ring 5 is made of highly elastic, wear-resistant silicone rubber. Silicone rubber has excellent temperature resistance, with a typical operating temperature range of -70 to 260℃. It is non-toxic and odorless, and also possesses excellent heat resistance, cold resistance, ozone resistance, atmospheric aging resistance, and good insulation properties. This material allows the dustproof sealing ring 5 to maintain stable physical properties during long-term use, resisting aging and deformation. Furthermore, during installation, even under pressure, the first sealing arm, second sealing arm, first sealing lip, and second sealing lip all undergo elastic deformation and tightly adhere, forming a robust sealing barrier.

[0035] like Figure 4 As shown, the cover 3 extends around the box 2 with limiting protrusions 33. These limiting protrusions 33 correspond to the limiting grooves 211 opened around the boss part 21, ensuring the accurate position of the cover 3 during installation and also enhancing the connection stability between the cover 3 and the box 2.

[0036] Furthermore, such as Figure 4 , Figure 6 As shown, this embodiment also includes a dustproof ring 6, which is installed in the annular dustproof groove 22 opened on the side wall of the box body 2.

[0037] The dustproof ring 6 is made of polytetrafluoroethylene (PTFE). PTFE as a ring material has many significant characteristics: it has high working precision, which can meet various precision requirements; it has excellent chemical resistance and is suitable for almost all media; it does not harden or break, has a wide operating temperature range, and can maintain stable performance at a high temperature of 177℃ without aging; and it has low friction.

[0038] In this embodiment, as Figure 6 As shown, the dustproof ring 6 includes an integrally connected side plate portion 61, a connecting portion 62, and a sealing portion 63.

[0039] exist Figure 6 When the cover 3 is installed in place, the sealing part 63 elastically presses against the annular groove 321 opened on the outer edge 32, forming another tight dustproof line, effectively preventing dust from entering from the gap between the cover 3 and the box 2.

[0040] During operation, both the dustproof sealing ring 5 and the dustproof retaining ring 6 are in a dynamic sealing state. With the operation of the roller shutter motor and minor environmental vibrations, the dustproof sealing ring 5 and the dustproof retaining ring 6 can adaptively adjust their deformation, maintaining a tight fit between the housing 2 and the cover 3, effectively preventing dust from entering through the gap between the cover 3 and the housing 2. This dynamic sealing design not only improves dustproof performance but also extends the service life of the terminal box, ensuring stable operation of the roller shutter motor in harsh environments.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
