Description

Technical Field

[0001] This utility model relates to the field of dustproof technology, and specifically discloses a dustproof housing for a switch. Background Technology

[0002] A switch dust cover is a protective device installed on the outside of a switch. It is mainly used to protect the switch and prevent electric shock. The switch dust cover is an important device to ensure the safety of the switch and extend its service life.

[0003] Existing switch dust covers are typically glued to the wall with adhesive. After prolonged use, the dust cover yellows. When replacement is desired, forcibly removing it due to its adhesive attachment can easily damage the wall. Furthermore, in kitchens with heavy grease, removing the dust cover for cleaning is difficult due to its integral connection, making thorough cleaning challenging. Only surface wiping is possible, resulting in incomplete cleaning of the internal dirt and negatively impacting the switch's lifespan and aesthetics in various usage scenarios. Utility Model Content

[0004] To solve the above problems, this utility model discloses a dustproof housing for a switch, which is achieved through the following technical solution.

[0005] A dustproof housing for a switch includes a switch panel, a bottom frame, a top frame, and a dustproof cover. Positioning bolts are evenly engaged around the circumference of the bottom frame, and clamping plates are fixed to the ends of the positioning bolts. First screw holes are formed at the four corners of the upper surface of the bottom frame, and second screw holes corresponding to the first screw holes are formed at the four corners of the upper surface of the top frame. Positioning screws are engaged in the first and second screw holes. The dustproof cover is rotatably connected to the rear side of the top frame.

[0006] Furthermore, a dustproof adhesive strip is fixed to the upper surface of the bottom frame.

[0007] Furthermore, a dust plug is inserted into the second screw hole on the top frame.

[0008] Furthermore, a dustproof pad is fixed to the side of the bottom frame that is in contact with the wall.

[0009] Furthermore, a rubber pad is fixedly attached to the clamping plate.

[0010] Furthermore, the top frame has a cable outlet hole, the inner wall of which is fixed with a rubber pad, and the dust cover has a corresponding cable outlet hole.

[0011] The technical solution provided by this utility model has the following advantages compared with the known public technology: by setting the engagement positioning bolt on the bottom frame, a stable connection between the dustproof shell and the switch panel is achieved. When the dustproof shell turns yellow or is damaged, the dustproof shell can be removed simply by loosening the positioning bolt. By opening screw holes with the same hole position on the bottom frame and the top frame, the threaded connection between the top frame and the bottom frame is achieved. When cleaning the dustproof cover, the top frame can be removed simply by loosening the positioning screw. Attached Figure Description

[0017] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-3As shown, this utility model provides a technical solution: a switch dustproof housing, including a switch panel 1, a bottom frame 2, a top frame 3, and a dustproof cover 4. The bottom frame 2 is uniformly engaged with positioning bolts 21 around its circumference. The ends of the positioning bolts 21 are fixedly connected to clamping plates 22. The four corners of the upper surface of the bottom frame 2 are provided with first screw holes 23. The four corners of the upper surface of the top frame 3 are provided with second screw holes 31 corresponding to the first screw holes 23. Positioning screws 31 are engaged in the first screw holes 23 and the second screw holes 31. The dustproof cover 4 is rotatably connected to the rear side of the top frame 3.

[0019] Preferably, a dustproof adhesive strip 24 is fixed to the upper surface of the bottom frame 2.

[0020] The junction between the bottom frame 2 and the top frame 3 is prone to dust accumulation. By setting up a dustproof strip 24, dust cannot be allowed to enter, making it cleaner to use.

[0021] Preferably, a dust plug 3 is inserted into the second screw hole 31 on the top frame 3.

[0022] By inserting a dust plug 3 into the second screw hole 31, dust can be prevented from getting into the screw hole, thus preventing it from being inconvenient to clean.

[0023] Preferably, a dustproof pad 25 is fixed to the side of the bottom frame 2 that is in contact with the wall.

[0024] To prevent uneven wall surfaces, a dustproof pad 25 is installed on the back of the bottom frame 2 to prevent dust from entering the switch through the gap between the wall and the bottom frame 2.

[0025] Preferably, a rubber pad 26 is fixedly attached to the clamping plate 22.

[0026] The rubber pad 26 allows the clamping plate 22 to clamp the switch panel 1 more securely, preventing damage to the switch panel 1 due to over-clamping.

[0027] Preferably, the top frame 3 has a cable outlet hole 34, and a rubber pad 26 is fixed to the inner wall of the cable outlet hole 34. The dust cover 4 has a corresponding cable outlet hole 34.

[0028] The top frame 3 and the dust cover 4 are provided with a wire outlet hole 34, which can ensure that the dust cover 4 can be perfectly closed when the plug is inserted into the switch panel 1, so as to achieve better dust protection. The inner wall of the wire outlet hole 34 is fixed with a dustproof pad 25, which can better facilitate the top frame 3 and the dust cover 4 to be in close contact with the wire, and achieve better sealing of the wire outlet hole 34.

[0029] One specific embodiment of this utility model is as follows:

[0030] When installing the dustproof housing, first place the bottom frame 2 on the switch panel 1, centering the switch panel 1 on the bottom frame 2. Then, rotate the positioning bolts 21 on all four sides of the bottom frame 2 to clamp the switch panel 1 with the clamping plates 22 at the ends of the positioning bolts 21. Stop rotating when the positioning bolts 21 become difficult to rotate. At this point, the bottom frame 2 is fixed to the switch panel 1. Next, place the top frame 3 on the bottom frame 2 and screw the positioning screws 31 into the first screw hole 23 and the second screw hole 31 to fix the top frame. Finally, close the dustproof cover 4 to complete the installation of the dustproof housing. When cleaning and maintaining the dustproof housing, loosen the positioning bolts 21 on all four sides of the bottom frame 2 to remove the dustproof housing. Then, loosen the positioning screws 31 in the first screw hole 23 and the second screw hole 31 to separate the bottom frame 2 and the top frame 3. Clean and wipe the top frame 3 and the top frame 3 separately.

[0031] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
