Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to a waterproof wall switch box. Background Technology

[0002] A wall switch is an electrical component installed on a wall to control the on / off state of a circuit. It can control the start and stop of lighting fixtures, sockets or other electrical appliances. It generally consists of a panel, switch button, internal contacts and wiring terminals.

[0003] Currently, switches are used in certain environments, especially in everyday spaces like bathrooms and kitchens where humidity is high and water is easily splashed. Without protection, the switch's internal components can become damp and short-circuit. Similarly, in outdoor areas like balconies and open corridors exposed to sun and rain, switches must have waterproof casings for durability. Therefore, a Chinese utility model patent with publication number CN212648084U, "A Waterproof Wall Switch Box," addresses this issue. This application uses a cover on the front of the base to directly block liquids from entering from the front of the base, thus providing waterproof protection for the internal wall switch. However, this application requires the switch panel to be pre-inserted into the mounting cavity of the base before it can be installed on the wall. The placement of the switch box within the wall makes disassembly and assembly inconvenient. While some waterproof boxes on the market use adhesive and can be directly pasted onto the wall near the switch panel for non-destructive installation, this method suffers from several drawbacks. The humid environment of kitchens and bathrooms accelerates adhesive aging, and temperature fluctuations cause repeated contraction and expansion, reducing adhesion and potentially leading to installation failure. Furthermore, when controlling multiple electrical devices in the same space, multiple switch panels are often installed in a row on the wall, resulting in insufficient spacing between them. In such cases, the structure on both sides of the waterproof box may be obstructed by adjacent switch panels, hindering its adhesion to the wall. Utility Model Content

[0004] The purpose of this utility model is to provide a waterproof wall switch box. By adjusting the top block and using the rubber pad, the problem of adhesive detachment can be avoided, making the installation more stable. The detachable side panel can accommodate single switches or multiple switches in the same row, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A waterproof wall switch box includes a mounting frame. A waterproof cover mounting groove is provided on the front side of the mounting frame. A side plate mounting groove is provided on the rear side of the mounting frame, with a side plate fixedly connected therein. A top block mounting groove is provided on the rear side of the mounting frame. A rectangular hole is provided at the top of the top block mounting groove, and a countersunk hole is provided at the bottom of the top block mounting groove. A top block is inserted through the rectangular hole. An adjusting screw is rotatably connected to the countersunk hole. A waterproof cover is slidably connected in the waterproof cover mounting groove.

[0007] As a further preferred embodiment of this utility model, the waterproof cover mounting groove is U-shaped, and sliding grooves are provided on both sides of the waterproof cover mounting groove to provide conditions for the waterproof cover to slide within the waterproof cover mounting groove. Positioning protrusions are fixedly connected to the upper positions on both sides of the waterproof cover mounting groove, thereby providing limiting conditions for the waterproof cover to close the front channel of the mounting frame.

[0008] As a further preferred embodiment of this utility model, the mounting frame located at the rear side of the waterproof cover mounting groove is coated with a sealing layer. The sealing layer is made of rubber and can seal the connection between the two mounting frames when they are spliced ​​together.

[0009] As a further preferred embodiment of this utility model, a toothed channel is provided in the mounting frame located above the sealing layer.

[0010] As a further preferred embodiment of this utility model, one side of the side plate is provided with a plurality of locking teeth. The longitudinal section of the locking teeth is a right-angled triangle. When two mounting frames are spliced, the two sides of the side plate are respectively inserted into the tooth channel of one of the mounting frames. Then, the locking teeth are pushed in one direction and locked in the tooth channel by utilizing their own elastic deformation characteristics. This improves the overall integrity of the assembly of multiple mounting frames when two mounting frames are assembled.

[0011] As a further preferred embodiment of this utility model, the outer contour of the side plate and the side plate mounting groove are fixedly connected by several connection points. When the mounting frame protects a single switch, the side plate does not need to be disassembled. However, when multiple mounting frames need to be spliced ​​together to protect multiple switches in the same row, the side plate can be disassembled from the side plate mounting groove through the connection points, so that multiple mounting frames can be spliced ​​together without affecting their insertion on the front side of the switch panel.

[0012] As a further preferred embodiment of this utility model, a screw groove is provided at the center of the bottom of the top block, and an adjusting screw located in the mounting groove of the top block is engaged with a retaining spring. The upper end of the adjusting screw is threadedly connected to the screw groove. When the mounting frame is attached to the wall with the help of the rubber pad on the rear side and is located outside the switch, the top of the mounting frame can abut against the top of the switch panel, and the top of the top block abuts against the bottom of the switch panel through the adjustment of the adjusting screw. This, together with the rubber pad used for mounting on the rear side of the mounting frame, improves the stability of the mounting frame installation.

[0013] As a further preferred embodiment of this utility model, sliders are fixedly connected to both sides of the waterproof cover. Slots are provided on both sides of the waterproof cover near the sliders. The sliders are slidably connected in one of the slots, and the slots are engaged with one of the positioning protrusions. The waterproof cover can be opened and closed by manually sliding it vertically in the waterproof cover mounting slot, thereby cooperating with the mounting frame to waterproof the switch.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. In this utility model, no complicated operation is required when using it alone. It is attached to the wall with the help of the rear rubber pad, and then the top block is moved to the bottom of the switch panel by adjusting the screw. With the limit of the top of the frame, the installation stability is greatly improved.

[0016] 2. In this utility model, when multiple mounting frames are spliced ​​together, the side panels can be directly removed, and two adjacent mounting frames can be connected by the removed side panels for additional reinforcement, which improves the overall integrity of the multiple mounting frames. In this way, the number of switches in the same row can be increased or decreased at will, solving the problem of multiple switches being difficult to adapt. Attached Figure Description

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] like Figures 1-8 As shown, the present invention provides a waterproof wall switch box, including a mounting frame 1, a waterproof cover mounting groove 2 on the front side of the mounting frame 1, a side plate mounting groove 3 on the rear side of the mounting frame 1, a side plate 4 fixedly connected in the side plate mounting groove 3, a top block mounting groove 5 on the rear side of the mounting frame 1, a rectangular hole 6 at the top of the top block mounting groove 5, a countersunk hole 7 at the bottom of the top block mounting groove 5, a top block 8 inserted into the rectangular hole 6, an adjusting screw 9 rotatably connected in the countersunk hole 7, and a waterproof cover 10 slidably connected in the waterproof cover mounting groove 2.

[0028] like Figures 1-3 As shown, the waterproof cover mounting groove 2 is U-shaped, and sliding grooves 11 are provided on both sides of the waterproof cover mounting groove 2 to provide conditions for the waterproof cover 10 to slide within the waterproof cover mounting groove 2. Positioning protrusions 12 are fixedly connected to the upper positions on both sides of the waterproof cover mounting groove 2, thereby providing limiting conditions for the waterproof cover 10 to close the front channel of the mounting frame 1. The mounting frame 1 located at the rear position of the waterproof cover mounting groove 2 is coated with a sealing layer 16. The sealing layer 16 is made of rubber and can seal the connection between the two mounting frames 1 when they are spliced ​​together. Toothed channels 13 are provided in the mounting frame 1 located above the sealing layer 16.

[0029] like Figure 3 , Figure 8As shown, one side of the side plate 4 is provided with several locking teeth 14. The longitudinal section of the locking teeth 14 is a right-angled triangle. When two mounting frames 1 are spliced, the two sides of the side plate 4 are respectively inserted into the tooth path 13 of one of the mounting frames 1. Then, the locking teeth 14 are pushed in one direction and locked in the tooth path 13 by their own elastic deformation characteristics. Thus, when two mounting frames 1 are assembled, the overall integrity of multiple mounting frames 1 is improved. The outer contour of the side plate 4 is fixedly connected to the side plate mounting groove 3 by several connection points 15. When the mounting frame 1 protects a single switch, the side plate 4 does not need to be removed. However, when multiple mounting frames 1 need to be spliced ​​to protect multiple switches in the same row, the side plate 4 can be removed from the side plate mounting groove 3 through the connection points 15. This makes it easy for multiple mounting frames 1 to be spliced ​​without affecting their insertion on the front side of the switch panel.

[0030] like Figure 2 , Figure 5 As shown, a screw groove 17 is provided at the center of the bottom of the top block 8. The adjusting screw 9 located in the mounting groove 5 of the top block is engaged with a retaining spring 18, and the upper end of the adjusting screw 9 is threadedly connected to the screw groove 17. When the mounting frame 1 is attached to the wall with the help of the rubber pad on the rear side and is located outside the switch, the top of the mounting frame 1 can abut against the top of the switch panel, and the top of the top block 8 abuts against the bottom of the switch panel through the adjustment of the adjusting screw 9, thereby improving the stability of the mounting frame 1 with the rubber pad used for mounting on the rear side of the mounting frame 1.

[0031] like Figures 1-4 As shown, sliders 19 are fixedly connected to both sides of the waterproof cover 10. Slots 20 are provided on both sides of the waterproof cover 10 near the sliders 19. The sliders 19 are slidably connected in one of the slide grooves 11, and the slots 20 are engaged with one of the positioning protrusions 12. The waterproof cover 10 is manually slid vertically in the waterproof cover mounting groove 2 to open and close, thereby cooperating with the mounting frame 1 to waterproof the switch.

[0032] It should be noted that this utility model is a waterproof wall switch box. During installation, the mounting frame 1 and the rubber pad on the back of the side plate 4 are first attached to the wall to ensure that the mounting frame 1 completely covers the switch panel. Then, the adjusting screw 9 in the countersunk hole 7 is rotated with a tool. Since the adjusting screw 9 is threadedly connected to the screw groove 17 at the bottom of the top block 8, the rotation will drive the top block 8 to move upward along the rectangular hole 6 until the top of the top block 8 is tightly against the bottom of the switch panel. Together with the rubber pad, it forms a two-way limit, which greatly improves the installation stability of the mounting frame 1 and avoids installation failure caused by humid environment or temperature difference.

[0033] When multiple switches in the same row need to be protected, the side plate 4 can be removed from the side plate mounting groove 3 using the connection point 15. The mating surfaces of two adjacent mounting frames 1 are then attached. The locking teeth 14 on one side of the removed side plate 4 are aligned with the toothed groove 13 of one of the mounting frames 1. The locking teeth 14 are pushed in one direction using the right-angled triangular structure of the right-angled triangle, so that the locking teeth 14 are elastically deformed and locked in the toothed groove 13, thus achieving a firm splicing of multiple mounting frames 1. Subsequently, as mentioned above, multiple mounting frames 1 are first pasted onto the wall and then further fixed by the top block 8. This allows for flexible increase or decrease of the number of mounting frames 1 according to the number of switches in the same row. The sealing layer 16 on one side of the mounting frame 1 is made of rubber, which can fill the gap at the joint of adjacent mounting frames 1 and prevent moisture from seeping in from the splicing point.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
