[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0038] like Figures 1 to 6As shown, an embodiment of the present invention provides a switch protection device, including: a base 1 with one end open and hollow inside, and a first alignment groove 2 adapted to the outer edge of the switch is provided in the middle of the bottom end of the inner cavity of the base 1.

[0039] The cover plate 4 is fixedly connected to the open end of the base 1 by screws. The middle part of the cover plate 4 is provided with a second alignment groove 44 of the same size as the first alignment groove 2. The outer side of the cover plate 4 is provided with four through grooves 43. The four through grooves 43 are parallel to the four sides of the second alignment groove 44 respectively. The outer side of the four through grooves 43 is surrounded by a limiting frame 41.

[0040] A protective cover 5 is located inside the limiting frame 41 and in contact with the cover plate 4. The protective cover 5 is a rectangular box-shaped structure with one open end and a hollow interior; and

[0041] The limiting component 6, located between the base 1 and the cover plate 4, is used to cooperate with the limiting frame 41 to clamp and limit the protective cover 5 so that the protective cover 5 and the cover plate 4 are tightly connected.

[0042] The back of the base 1 is provided with adhesive 3.

[0043] Because existing switch protection devices are inconvenient to clean.

[0044] This solution uses the limiting component 6 in conjunction with the limiting frame 41 to clamp and limit the protective cover 5, so that the protective cover 5 and the cover plate 4 fit tightly together, which can effectively block the interference of water vapor and dust on the switch and improve the service life of the switch. In addition, the limiting component 6 can also quickly release the restriction on the protective cover 5, which provides convenience for the removal, cleaning or replacement of the protective cover 5 in the future.

[0045] Specifically, the base 1 in this solution has an adhesive backing 3 on its back. During installation, the base 1 can be fixed to the wall where the switch is installed using the adhesive backing, so that the switch on the wall is located inside the first alignment groove 2 and the second alignment groove 44. After the protective cover 5 is fixed by the limiting component 6, it can completely cover the switch, thereby providing dustproof and moisture-proof protection for the switch. When the protective cover 5 is damaged or needs to be cleaned, the limiting component 6 can be used to release the fixing of the protective cover 5, and then the protective cover 5 can be removed for cleaning or replacement.

[0046] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the limiting component 6 includes:

[0047] The four rotating seats 601 located at the four corners of the inner cavity of the base 1 are rotatably connected to the bottom of the inner cavity of the base 1 by a shaft. The rotating seats 601 can be in the shape of "L".

[0048] A connecting strip 602 is provided between two adjacent rotating seats 601, and the two ends of the connecting strip 602 are rotatably connected to the ends of the rotating seats 601 through shafts;

[0049] An abutment head 603 is integrally formed with the middle of the top of the connecting strip 602. The abutment head 603 passes through the through groove 43 and extends to the outside of the cover plate 4.

[0050] A tension spring 604 is connected to one end of each of the three rotating seats 601, and the end of the tension spring 604 away from the rotating seat 601 is connected to the inner wall of the base 1.

[0051] A fixed seat 605 located on one side of one of the rotating seats 601;

[0052] A guide rod 606 is movably connected to the fixed base 605. One end of the guide rod 606 passes through the inner wall of the base 1 and extends to the outer side of the base 1 and is fixedly connected to the pressing head 607. The other end of the guide rod 606 is fixedly connected to a push block 608. A limit ring 6010 is fixedly connected to the outer wall of the middle part of the guide rod 606.

[0053] A return spring 609 is sleeved on the outer wall of the guide rod 606, and the return spring 609 is located between the fixed seat 605 and the limiting ring 6010.

[0054] Four rotating seats 601 and four connecting strips 602 are alternately connected end to end to form a rectangular frame structure, and the alignment groove 2 is located inside the rectangular frame.

[0055] When the rotating seat 601 rotates, the contact head 603 can move freely within the through groove 43;

[0056] One end face of the push block 608 is in close contact with one end of the rotating seat 601, and the contact surface between the push block 608 and the rotating seat 601 is an inclined surface.

[0057] In this embodiment, when it is necessary to release the fixation of the protective cover 5, the guide rod 606 can be moved by pressing the pressing head 607. The guide rod 606 will push the push block 608 to move. The rotating seat 601 will rotate under the pushing action of the push block 608. The rotating seat 601 will drive the two adjacent connecting bars 602 to move. The two moving connecting bars 602 will also drive the adjacent rotating seat 601 to rotate, thereby forcing the other three rotating seats 601 and the four connecting bars 602 to move inward. The four connecting bars 602 will move inward, so that the contact head 603 is away from the inner wall of the protective cover 5, and the fixation of the protective cover 5 can be released, and the protective cover 5 can be removed.

[0058] It should be noted that when the pressing head 607 is released, the compressed reset spring 609 will push the limit ring 6010, thereby forcing the guide rod 606 to move outward to reset the base 1.

[0059] When the protective cover 5 needs to be installed, press the pressing head 607 to move all four contact heads 603 inward. Then place the protective cover 5 inside the limiting frame 41 and release the pressing head 607. The three rotating seats 601 will be driven to rotate by the reset action of the corresponding position tension springs 604. At the same time, the four contact heads 603 will abut against the four inner walls of the protective cover 5 respectively, forming a fixed limit on the protective cover 5.

[0060] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, the protective cover 5 includes a docking part 501 with a rectangular frame structure; and a protective part 502 fixedly connected to the docking part 501; the docking part 501 is made of hard plastic, and the protective part 502 is made of transparent soft rubber.

[0061] In this embodiment, the protective cover 5 mainly includes a docking part 501 and a protective part 502. The protective part 502 is a rectangular box-shaped structure with one end open. It is made of transparent soft rubber material, which not only makes it easy to observe the switch from the outside, but also allows the switch to be pressed even through the protective structure without having to fully open the protective cover. This reduces the interference of dust and moisture on the switch and thus improves the service life of the switch.

[0062] In a further preferred embodiment of this utility model, such as Figure 1-6 As shown, a sealing strip 42 is adhered to the inner wall of the limiting frame 41.

[0063] In this embodiment, sealing strips 42 are provided around the inner sidewall of the limiting frame 41. The sealing strips 42 are tightly fitted with the mating part 501 of the protective cover 5, thereby improving the sealing performance of the connection between the protective cover 5 and the cover plate 4.
