Description

Technical Field

[0001] This utility model relates to the field of electrical wiring equipment technology, and in particular to an electrical junction box. Background Technology

[0002] In electrical installations, junction boxes are often used as transitional devices for cable connections. Wires inside conduits are connected in the junction box, which serves to protect and connect the wires.

[0003] Most junction boxes are currently installed directly into mounting holes in the wall. Due to the different slot sizes of the mounting holes, there is often a mismatch between the size of the mounting hole and the size of the junction box. During construction, the junction box is often fixed by filling the gap between it and the mounting hole with construction debris. This method often leads to local damage to the junction box and makes it difficult to adjust the position of the junction box in the mounting hole, affecting the use of the junction box. Utility Model Content

[0004] The purpose of this utility model is to provide an electrical junction box that solves the problem that existing fixing methods can easily lead to damage to the junction box and make it impossible to adjust the position of the junction box in the mounting hole.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] An electrical junction box includes a box body with wiring ports on all four side walls. A rectangular slot is formed in the center of each side wall. An adjusting component is provided on the inner side of the side wall. The adjusting component includes a first vertical plate, a horizontal plate, an inclined plate, and a second vertical plate arranged sequentially from top to bottom. The first and second vertical plates are collinear and fixedly connected to the inner side of the side wall. The inclined plate corresponds to the rectangular slot. An adjusting screw hole is provided on the horizontal plate, and a fastener is installed on the adjusting screw hole. A fixing block is movably inserted into the rectangular slot. The inner end of the fixing block has an inclined surface adapted to the inclined plate, and the outer end of the fixing block has a clamping block.

[0007] Furthermore, the inner wall of the box is provided with top cover fixing blocks at the four corners, and the top cover fixing blocks are threadedly connected to the top cover.

[0008] Furthermore, the lower part of the outer wall of the clamping block is provided with an arc-shaped surface.

[0009] Furthermore, the inclined plate has anti-detachment strip holes, and the upper end of the anti-detachment strip holes has placement holes. The size of the placement holes is larger than that of the anti-detachment strip holes, and the inclined surface has anti-detachment blocks that are adapted to the placement holes and anti-detachment strip holes.

[0010] Furthermore, the inner side of the sidewall is provided with a positioning groove that adapts to the first vertical plate and the second vertical plate.

[0011] Furthermore, a baffle is provided on the wiring port, the size of which is smaller than that of the wiring port, and the baffle is connected to the wiring port through a fragile part.

[0012] This utility model has the following advantages:

[0013] 1. The movement of the fastener pushes the fixing block and the clamping block downwards. At the same time, the inclined plate will squeeze the fixing block outwards, causing the clamping block to move to contact the inner wall of the mounting hole, thereby fixing the junction box in the mounting hole. The operation is simple and convenient.

[0014] 2. By adjusting the movement of fasteners in multiple directions, the position of the junction box in the mounting hole can be finely adjusted, which facilitates cable laying and connection and makes it more practical. Attached Figure Description

[0025] refer to Figure 1-3 As shown, one embodiment of this utility model is as follows:

[0026] An electrical junction box includes a box body 1. Each of the four side walls 101 of the box body 1 is provided with a wiring port 2. A rectangular slot 3 is opened in the center of each side wall 101. An adjusting component is provided on the inner side of each side wall 101. The adjusting component includes a first vertical plate 4, a horizontal plate 5, an inclined plate 6, and a second vertical plate 7 arranged sequentially from top to bottom. The first vertical plate 4 and the second vertical plate 7 are arranged collinearly and are fixedly connected to the inner side of the side wall 101. The inclined plate 6 corresponds to the rectangular slot 3. An adjusting screw hole 8 is provided on the horizontal plate 5. A fastener 9 is installed on the adjusting screw hole 8. A fixing block 10 is movably inserted into the rectangular slot 3. The inner end of the fixing block 10 is provided with an inclined surface adapted to the inclined plate 6. The outer end of the fixing block 10 is provided with a pressing block 11.

[0027] Specifically, for ease of installation, the inner side of the side wall 101 is provided with a positioning groove 12 that adapts to the first vertical plate 4 and the second vertical plate 7. The first vertical plate 4 and the second vertical plate 7 are fixed by adhesive after being placed in the positioning groove 12. Since the adhesive fixation requires waiting for the adhesive to solidify, the adjusting parts can be fixed in advance during actual construction. It is understood that since the box body and the adjusting parts are made of plastic, the adjusting parts can also be fixed to the side wall 101 with small screws.

[0028] During installation, one or more adjustment components can be selected for installation as needed. After the adjustment components are fixed, the fixing block 10 is inserted from the outside of the box into the rectangular slot and contacts the inclined plate. Then, the box body 1 is placed into the mounting hole in the wall, and the fastener 9 is screwed into the adjusting screw hole 8. The movement of the fastener 9 pushes the fixing block 10 and the clamping block 11 downwards. At the same time, the inclined plate 6 presses the fixing block 10 outwards, causing the clamping block 11 to move to contact the inner wall of the mounting hole, thereby fixing the junction box in the mounting hole. By adjusting the amount of movement of the fastener 9 in multiple directions, the position of the junction box in the mounting hole can be finely adjusted, which facilitates cable laying and connection, and improves practicality.

[0029] Because the inclined plate 6 is subjected to pressure from the fixing block 10, to reduce the probability of the adjusting component breaking under pressure, the first vertical plate 4, the horizontal plate 5, the inclined plate 6, and the second vertical plate 7 are integrally molded. The first vertical plate 4 and the second vertical plate 7 are respectively located on both sides, thereby achieving a fixed connection on both sides and preventing the adjusting component from falling off under pressure. The overall or partial thickness of the adjusting component can be set according to the actual situation, and a more resilient plastic material is selected.

[0030] After the cables are connected inside the box, the top cover 13 is installed. To facilitate installation, the four corners of the inner wall of the box are provided with top cover fixing blocks 14. The top cover fixing blocks 14 are provided with threaded holes and are fixed to the top cover by threaded connection, which is convenient for maintenance.

[0031] For ease of installation, as shown in the figure, the lower part of the outer wall of the clamping block 11 is provided with an arc-shaped surface 15. The arc-shaped surface 15 reduces the lower part of the outer wall of the clamping block 11, and the arc shape also helps to reduce resistance, thus making it easier to move the fixing block and the clamping block, and improving the stability after installation and fixing.

[0032] Furthermore, to prevent the fixing block 10 from falling off during installation and to improve installation efficiency, the inclined plate 6 is provided with an anti-detachment strip hole 16, and the upper end of the anti-detachment strip hole 16 is provided with a placement hole 17. The size of the placement hole 17 is larger than that of the anti-detachment strip hole 16, and the inclined surface is provided with an anti-detachment block 18 that is adapted to the placement hole 17 and the anti-detachment strip hole 16.

[0033] Specifically, the anti-detachment block 18 can adopt a T-shaped structure, with a size smaller than that of the placement hole 17, so that the outer horizontal part of the T-shaped anti-detachment block 18 can pass through the placement hole 17 and thus slide and lock onto the anti-detachment strip hole 16. This effectively avoids the problem of the fixing block 10 falling off during installation.

[0034] In this embodiment, a baffle 19 is provided on the wiring port 2. The size of the baffle 19 is smaller than the size of the wiring port 2, and the baffle 19 is connected to the wiring port 2 through a fragile component.

[0035] During installation, depending on actual installation needs, one or more vulnerable parts of the baffle 19 can be broken to release the wiring port 2, facilitating cable entry into the housing 1. The number of wiring ports 2 on the side wall 101 can be set multiple times according to actual needs, such as... Figure 1 As shown, in this embodiment, there are two wiring ports 2 on each sidewall 101.

[0036] Although the present invention 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 invention should be included within the protection scope of the present invention.
