Description

Technical Field

[0001] This utility model relates to the field of electrical engineering and safety technology, specifically a moisture-proof and waterproof switch box for building electrical appliances. Background Technology

[0002] In building electrical systems, switch boxes are key components connecting electrical equipment and wiring, and their performance directly affects electrical safety and equipment lifespan. Traditional switch boxes can generally meet the requirements in dry environments, but in humid, rainy, or corrosive environments, such as bathrooms, kitchens, basements, and outdoor landscape lighting, moisture and humidity can easily penetrate the box, leading to short circuits in electrical components, decreased insulation performance, corrosion and rusting of metal parts, and even safety accidents such as leakage and fire.

[0003] A search revealed existing technology (application number: CN201410651369.9), which describes a "waterproof housing for a switch box". This utility model includes a housing and a cover, with a fixing plate, a cover plate, and a sealing plate all made of the same soft rubber sheet. A deformation shaft is provided between the fixing plate and the cover plate, and an iron sheet is encapsulated inside the sealing plate. A magnet block that works in conjunction with the iron sheet is provided at the bottom of the housing.

[0004] However, while existing technologies improve overall airtightness and waterproofing, they still have some shortcomings: the vents are located at the top, and when the warm, humid air inside the box rises and comes into contact with the low-temperature waterproof membrane, condensation easily forms on the membrane surface. If the waterproof membrane only prevents liquid water from entering, water vapor will accumulate under the membrane, creating a humid environment that corrodes the circuit board. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a moisture-proof and waterproof switch box for building electrical appliances.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a moisture-proof and waterproof switch box for building electrical appliances, comprising: a switch box, the exterior of which is square-shaped, and a glue-filled base fixedly installed at the bottom; the glue-filled base, the exterior of which is funnel-shaped, and the interior of which has a through groove with the bottom of the switch box for connecting the wiring; an isolation plate, fixedly installed inside the switch box for isolating moisture; a baffle, slidably installed inside the switch box; a pull rod, fixedly connected to a fixing device for controlling the fixing device; a fixing device, the top of which is fixedly connected to the bottom of the switch box for fixing the baffle; and a button, fixedly installed inside the isolation plate for controlling the internal circuit switch.

[0007] As a further description of the above technical solution:

[0008] The fixing device includes: a spring, one end of which is fixedly mounted on the fixing device and the other end of which is fixedly mounted on the protrusion for resetting the protrusion; a sliding column, which is fixedly connected to the protrusion and whose other end is slidably connected through the fixing device; the protrusion, which is fixedly connected to an iron rod inside; and an iron rod, which is fixedly connected to a pull rod at both ends for driving the protrusion.

[0009] As a further description of the above technical solution:

[0010] A grooved plate, formed at the bottom of the baffle, and its shape matches the protrusion, is used to fix the baffle in the vertical direction.

[0011] As a further description of the above technical solution:

[0012] The protrusions and grooves are arranged in a trapezoidal shape.

[0013] As a further description of the above technical solution:

[0014] The potting base is made of butyl rubber, a high-molecular waterproof material, which has excellent waterproof performance and chemical corrosion resistance.

[0015] As a further description of the above technical solution:

[0016] The fixing device is I-shaped, and the height of the middle space is slightly greater than the height of the protrusion, providing space for the protrusion to slide.

[0017] As a further description of the above technical solution:

[0018] The counterweight is fixedly installed on the top of the baffle and has a groove inside, which is used to drive the baffle to close vertically by its own weight.

[0019] This utility model has the following beneficial effects:

[0020] 1. By using a glue-filled base and a funnel-shaped structure to seal the circuit inlet, and with the isolation plate to isolate internal moisture, the baffle automatically closes with the help of counterweights, forming a three-dimensional protection that can adapt to humid building environments.

[0021] 2. The fitting design of the protrusion and the groove plate makes the baffle more stable; the I-shaped fixing device provides space for the protrusion to slide, the spring assists in the reset, and the pull rod is easy to operate, which takes into account both protection performance and usage flexibility.

[0030] Example 1:

[0031] like Figures 1 to 3 As shown in the figure, this embodiment provides a moisture-proof and waterproof switch box for building electrical appliances, including: a switch box 1, which is square in shape on the outside and has a glue-filled base 2 fixedly installed at the bottom; the glue-filled base 2 is funnel-shaped on the outside and has a through groove opened in the inside and at the bottom of the switch box 1 for connecting the circuit; an isolation plate 3, which is fixedly installed inside the switch box 1 for isolating moisture; a baffle 4, which is slidably installed inside the switch box 1; a pull rod 5, which is fixedly connected to a fixing device 6 for controlling the fixing device 6; the fixing device 6, which is fixedly connected to the bottom of the switch box 1 at the top for fixing the baffle 4; and a button 7, which is fixedly installed inside the isolation plate 3 for controlling the internal circuit switch.

[0032] In this embodiment, the fixing component and the sealing component constitute a moisture-proof and waterproof switch box for building electrical appliances according to this application.

[0033] It should also be understood that the buttons are common knowledge in this field, and since they are only used and not modified, the control method and circuit connection will not be described in detail.

[0034] In addition, in this embodiment, the switch box 1 is vertically fixed to the wall with expansion screws during use. The wiring can be connected to the inside of the switch box 1 through the through groove of the bottom potting base 2. In addition, the internal isolation plate 3 will further prevent moisture from entering the wiring. At the same time, when the external baffle 4 is vertically closed, it will prevent external rainwater from entering. When the baffle 4 is opened, the pull rod 5 is pulled back. The pull rod 5 drives the protrusion 63 to disengage from the bottom groove of the pull rod 5. At the same time, the protrusion 63 will compress the spring 61. After the baffle 4 is opened, the circuit switch installed inside can be controlled by the button 7. When the pull rod 5 is released, the spring 61 will reset the protrusion 63, which will be used to fix the baffle 4 when it is closed next time. When closed, the baffle 4 can be automatically closed by the weight of the counterweight 42.

[0035] Specifically, the fixing device 6 includes: a spring 61, one end of which is fixedly mounted on the fixing device 6 and the other end of which is fixedly mounted on the protrusion 63, for resetting the protrusion 63; a sliding column 62, which is fixedly connected to the protrusion 63 and the other end of which is slidably connected to the fixing device 6; the protrusion 63, which is fixedly connected to the iron rod 64 inside; and the iron rod 64, which is fixedly connected to the pull rod 5 at both ends, for driving the protrusion 63.

[0036] In this embodiment, pulling the lever 5 causes the iron rod 64 to move, so that the protrusion 63 slides on the fixing device 6 via the sliding column 62. The spring 61 generates elastic force after the protrusion 63 moves, which is used to reset the protrusion 63.

[0037] Specifically, the groove plate 41 is formed at the bottom of the baffle 4 and its shape matches the protrusion 63, and is used to fix the baffle 4 in the vertical direction.

[0038] In a preferred embodiment, when the protrusion 63 is engaged with the groove plate 41, the baffle 4 is fixed in the vertical direction and cannot move, thus fixing the baffle 4 and preventing external rainwater from entering.

[0039] Example 2:

[0040] Based on Example 1, in order to further improve the stability of the fixing device, a protrusion structure is arranged inside the fixing device 6;

[0041] Specifically, the protrusion 63 and the groove plate 41 are arranged in a trapezoidal shape.

[0042] In this embodiment, the trapezoidal structure makes the protrusion 63 fit more tightly with the groove plate 41, improving the stability of the fixed baffle 4 and preventing the baffle 4 from moving accidentally in the vertical direction.

[0043] Specifically, the potting base 2 is made of butyl rubber, a high-molecular waterproof material, which has excellent waterproof performance and chemical corrosion resistance.

[0044] This design utilizes the material properties of butyl rubber to seal the gaps at the wiring connection points, preventing moisture and corrosive substances from entering the switch box 1.

[0045] Example 3:

[0046] Based on embodiment 2, in order to assist the fixing device and the reset mechanism in working, an I-shaped structure is arranged on the inner side of the fixing device 6;

[0047] Specifically, the fixing device 6 is I-shaped, and the height of the middle space is slightly greater than the height of the protrusion 63, providing space for the sliding of the protrusion 63.

[0048] The central space of the I-shaped structure allows the protrusion 63 to slide, ensuring that the protrusion 63 can move smoothly to fix and release the baffle 4.

[0049] Specifically, the counterweight 42 is fixedly installed on the top of the baffle 4, and has a groove inside, which is used to drive the baffle 4 to close vertically by its own weight.

[0050] In this embodiment, the counterweight 42 acts on the top of the baffle 4 due to its own weight. When the fixing device 6 releases the baffle 4, the counterweight 42 drives the baffle 4 to slide vertically downward, thereby sealing the inside of the switch box 1.

[0051] In actual use, the switch box 1 is vertically fixed to the wall with expansion screws. The wiring can be connected to the inside of the switch box 1 through the through groove of the bottom potting base 2. In addition, the internal isolation plate 3 will further prevent moisture from entering the wiring. At the same time, when the external baffle 4 is vertically closed, it will prevent external rainwater from entering. When the baffle 4 is opened, pull the lever 5 backward. The lever 5 will drive the protrusion 63 to disengage from the bottom groove of the lever 5. At the same time, the protrusion 63 will compress the spring 61. After the baffle 4 is opened, the circuit switch installed inside can be controlled by the button 7. When the lever 5 is released, the spring 61 will reset the protrusion 63, which will be used to fix the baffle 4 when it is closed next time. When closed, the baffle 4 can be automatically closed by the weight of the counterweight 42.

[0052] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
