Description

Technical Field

[0001] This utility model relates to the field of electrical equipment, and more specifically, to a switch box that facilitates nut replacement. Background Technology

[0002] A junction box is a basic connection and protection device widely used in electrical, electronic, communication, and photovoltaic power generation fields. Electrical wires used in decoration pass through conduits, and the wires inside the conduits are connected in the junction box. Switches or sockets are fixed to the junction box with screws at the opening. Its core function is to provide a safe, reliable, orderly and protective environment for the connection points of wires, cables or other conductors.

[0003] Existing switch boxes generally consist of two main parts: the switch panel and the switch base box. The base box is usually installed behind the socket or switch and buried in the wall. To connect and fix these two parts, screws and nuts are generally used. During the use of the recessed switch box base, the base box ears may be damaged or the fasteners may be blocked by concrete. After long-term use, the fastener components may age and become damaged, making the switch box unable to meet the usage requirements. If the damaged switch box base continues to be used, there are many hidden dangers. If the switch box is replaced, it will damage the original appearance of the wall and its covering, which is time-consuming and laborious.

[0004] The existing switch box fastening nuts are fixedly installed on the bottom plate of the switch box. The nuts are usually held in the stud hole of the switch box by a combination of forced locking and clamping. The nuts are set in the fixing seat, and the fixing seat and the switch box body are an integral structure. The fastening nuts and the switch box are basically one piece. If the fastening nuts are damaged, the switch box cannot be used. The existing technology lacks a switch box that makes it easy to replace the nuts. Utility Model Content

[0005] The purpose of this utility model is to overcome the problem that the existing technology lacks a switch box with an easy-to-replace nut, and to provide a switch box with an easy-to-replace nut, which can be easily removed and replaced when the fastening nut is damaged, without having to replace the entire switch box.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A switch box for easy nut replacement is provided, comprising a box body, a nut replacement part, and a positioning cover located inside the box body. One or more side walls of the box body are provided with through grooves. The nut replacement part is slidably connected to the through grooves. When the nut replacement part slides to abut against the inner side wall of the through groove, the positioning cover is installed in the through groove, and the positioning cover presses the nut replacement part against the inner side wall of the through groove.

[0008] This utility model discloses a switch box for easy nut replacement. The box body is embedded inside the wall. When the nut replacement part is damaged, the operator can first remove the positioning cover to release the damaged nut replacement part, then remove the damaged nut replacement part. The operator then takes a spare nut replacement part, inserts it into the through groove, and slides it into the groove until it abuts against the inner wall of the groove. The positioning cover is then installed in the through groove, securing the nut replacement part against the inner wall of the groove, thus completing the nut replacement. Compared to existing technologies, this solution allows for easy removal and replacement of the damaged nut replacement part without replacing the entire switch box, reducing workload and cost, and improving convenience. The positioning cover secures the nut replacement part, allowing operation from inside the box, and the disassembly and assembly are quick and convenient.

[0009] Furthermore, the through groove includes an insertion groove and a sliding groove that are interconnected. The insertion groove is used for the nut replacement part to extend into, and the nut replacement part is slidably connected to the sliding groove. The insertion groove allows the nut replacement part to extend into, making it easier to insert and remove. The sliding groove not only guides the nut replacement part but also restricts its displacement using the support of the groove wall.

[0010] Furthermore, the nut replacement component includes a slider, a fastening nut mounted on the slider, and a baffle connected to one end of the slider. The slider is slidably connected to the sliding groove, and the baffle abuts against the outer wall of the box. When the slider slides to abut against the inner wall of the sliding groove, the baffle abuts against the outer wall of the box, restricting the slider from moving in a direction perpendicular to the slider's sliding direction, preventing the slider from disengaging from the sliding groove, thus improving the fixing effect and stability of the nut replacement component.

[0011] Furthermore, an elongated hole is provided on one side of the slider, and an adjustment cavity is provided inside the slider. The elongated hole communicates with the adjustment cavity, and the fastening nut is located inside the adjustment cavity and slidably connected to it. The sliding direction of the fastening nut is consistent with the extension direction of the elongated hole. Since the fastening nut is slidably connected within the adjustment cavity, its position can be finely adjusted. The screw passes through the elongated hole and is threadedly connected to the fastening nut. The fastening nut is designed to be finely adjustable, allowing the screw to be aligned during switch panel installation by adjusting its position, preventing screw misalignment and improving installation accuracy.

[0012] Furthermore, a first protrusion is provided on one side of the positioning cover. When one side of the nut replacement part abuts against the inner wall of the through groove, the first protrusion is inserted into the through groove, and the positioning cover covers the part of the through groove not connected to the nut replacement part. When the nut replacement part abuts against the inner wall of the through groove, the first protrusion is inserted into the through groove, which can fix the positioning cover. The positioning cover, together with the nut replacement part, can also cover the through groove, effectively preventing concrete and other debris from entering the box and causing damage to the nut replacement part or wiring inside the box, thus extending the service life of the switch box.

[0013] Furthermore, the first protrusion fits into the through groove with a clearance. Assembly and disassembly are convenient, requiring no excessive force; it can be operated manually to remove the positioning cover, while also providing a certain degree of stability to prevent it from falling off.

[0014] Furthermore, it also includes a protective cover, which is installed on the outer wall of the box and is used to cover the through slot. The protective cover covering the through slot effectively prevents debris such as concrete from entering the box and damaging the wiring or nut replacement parts inside the box, thus extending the service life of the switch box.

[0015] Furthermore, the side wall of the box body is provided with a second protrusion, which surrounds the opening of the through groove. A third protrusion is provided on one side of the protective cover, and the third protrusion is inserted into the second protrusion. The insertion of the third protrusion into the second protrusion secures the protective cover to the box body. The second protrusion surrounding the opening of the through groove means that the projection of the through groove onto the side wall of the box body lies within the closed structure formed by the projection of the second protrusion onto the side wall of the box body, resulting in a better sealing effect.

[0016] Furthermore, a sealing ring is provided on the outer side of the third protrusion. When the protective cover is installed on the box body, the sealing ring is located between the third protrusion and the second protrusion. The sealing ring located between the third protrusion and the second protrusion reduces the penetration of moisture into the box body and improves the sealing performance of the box body.

[0017] Furthermore, the side wall of the housing is provided with several wiring holes. The wiring holes allow conduits to pass through and enter the interior of the housing.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. Compared with existing technologies, when the nut replacement part in this solution is damaged, it can be disassembled and replaced with a new one without replacing the entire switch box, reducing workload and cost, and providing better convenience;

[0020] 2. The fastening nut is designed to be finely adjusted. When installing the outer cover, the position of the fastening nut can be adjusted to align the screw, preventing the screw from being misaligned and improving installation accuracy.

[0021] 3. The positioning cover is installed in the through groove and covers the through groove. This can not only press the nut replacement part against the inner wall of the sliding groove, improving the stability of the nut replacement part, but also effectively prevent concrete and other debris from entering the box and causing damage to the nut replacement part or wiring inside the box, thus extending the service life of the switch box.

[0022] 4. The protective cover effectively prevents debris such as concrete from entering the box and damaging the wiring or nut replacement parts inside the box, thus extending the service life of the switch box. The sealing ring improves the sealing performance of the box. Attached Figure Description

[0034] Example 1

[0035] This embodiment is a first embodiment of a switch box that facilitates nut replacement, such as... Figure 1 As shown, the device includes a rectangular box 100, two nut replacement parts, and two positioning covers 300 located inside the box 100. One of the positioning covers 300 is not shown in the figure. On the four side walls of the box 100, two opposite side walls each have three wiring holes 130, and the other two opposite side walls each have two wiring holes 130, as shown in the figure. Figure 2As shown, two through slots 110 are respectively opened on the two opposite side walls of the box body 100. The through slots 110 include an extension slot 111 and a sliding slot 112 that are connected to each other. The nut replacement part 200 includes a slider 210, a fastening nut 220 and a baffle 230 connected to one end of the slider 210.

[0036] like Figure 3 and Figure 4 As shown, a long hole 211 is provided on one side of the slider 210, and an adjustment cavity 212 is provided inside the slider 210. The long hole 211 communicates with the adjustment cavity 212. The fastening nut 220 is located inside the adjustment cavity 212 and is slidably connected to the adjustment cavity 212. The sliding direction of the fastening nut 220 is consistent with the extension direction of the long hole 211.

[0037] The insertion groove 111 is used for the baffle 230 and the slider 210 to extend into. The slider 210 is slidably connected to the sliding groove 112. When the slider 210 slides to abut against the inner side wall of the sliding groove 112, the baffle 230 abuts against the outer side wall of the box 100. The positioning cover 300 is installed in the through groove 110. The positioning cover 300 presses the slider 210 against the inner side wall of the through groove 110.

[0038] The working principle of this embodiment is as follows:

[0039] This utility model discloses a switch box for easy nut replacement. The box body 100 is embedded inside the wall. The wiring hole 130 allows the conduit to pass through and enter the box body 100. When the nut replacement part 200 is damaged, the operator can first remove the positioning cover 300 to release the damaged nut replacement part 200. Then, the damaged nut replacement part 200 is taken out from the insertion groove 111. After that, the operator takes the spare nut replacement part 200, inserts it into the insertion groove 111, and slides it into the sliding groove 112 until it abuts against the inner side wall of the sliding groove 112. Then, the positioning cover 300 is installed in the through groove 110, and the nut replacement part 200 is pressed against the inner side wall of the through groove 110, thereby completing the replacement of the nut replacement part 200.

[0040] The beneficial effects of this utility model are as follows:

[0041] Compared to existing technologies, the nut replacement part 200 in this solution can be disassembled and replaced with a new one when damaged, without replacing the entire switch box, reducing workload and cost, and providing better convenience. The nut replacement part 200 is fixed by the positioning cover 300, allowing operation from inside the box 100, and the disassembly and assembly are quick and convenient. The baffle 230 abuts against the outer wall of the box 100, restricting the slider 210 from moving in a direction perpendicular to the sliding direction of the slider 210, preventing the slider 210 from disengaging from the sliding groove 112. The fixing effect of the nut replacement part 200 is better, and the stability is better.

[0042] The fastening nut 220 is slidably connected within the adjusting cavity 212, so the position of the fastening nut 220 can be finely adjusted within a range of 2mm-5mm. The screw passes through the elongated hole 211 and is threadedly connected to the fastening nut 220. The fastening nut 220 is designed to be finely adjusted, so that the position of the fastening nut 220 can be adjusted to align the screw when installing the switch panel, thus avoiding screw misalignment and improving installation accuracy.

[0043] Example 2

[0044] This embodiment is a second embodiment of a switch base box that facilitates nut replacement. This embodiment is similar to the first embodiment, except that, as shown in the example... Figure 5 As shown, a first protrusion 310 is provided on one side of the positioning cover 300, such as... Figure 1 As shown, when one side of the nut replacement part 200 abuts against the inner wall of the through groove 110, the first protrusion 310 is inserted into the through groove 110, and the positioning cover 300 covers the part of the through groove 110 that is not connected to the nut replacement part 200. The first protrusion 310 and the through groove 110 are in clearance fit.

[0045] When the nut replacement part 200 abuts against the inner wall of the through groove 110, the first protrusion 310 is inserted into the through groove 110, which can fix the positioning cover 300. The positioning cover 300 can also cover the through groove 110 together with the nut replacement part 200, effectively preventing concrete and other debris from entering the box 100 and causing damage to the nut replacement part 200 or the wiring inside the box 100. This can extend the service life of the switch box. The clearance fit makes assembly and disassembly convenient. No excessive force is required. It can be operated by hand to remove the positioning cover 300. At the same time, it has a certain degree of stability to prevent it from falling off.

[0046] The remaining working principles of this embodiment are the same as those of Embodiment 1.

[0047] Example 3

[0048] This embodiment is a third embodiment of a switch base box that facilitates nut replacement. This embodiment is similar to embodiment two, except that, as... Figure 1 As shown, it also includes two protective covers 400, which are respectively installed on the outer surfaces of two opposite side walls of the box body 100. One protective cover 400 is not shown in the figure. The side wall of the box body 100 is provided with a second protrusion 120, which surrounds the opening of the through groove 110, as shown. Figure 6As shown, a third protrusion 410 is provided on one side of the protective cover 400 to limit the displacement of the nut replacement part 200 of the baffle 230, thus improving stability. The third protrusion 410 is inserted into the second protrusion 120, and a sealing ring is provided on the outer side of the third protrusion 410. When the protective cover 400 is installed on the box 100, the sealing ring is located between the third protrusion 410 and the second protrusion 120, and the inner side of the protective cover 400 abuts against one side of the baffle 230.

[0049] The protective cover 400 covers the through groove 110, which can effectively prevent concrete and other debris from entering the box 100 and causing damage to the wiring or nut replacement parts 200 inside the box 100, thus extending the service life of the switch box. The third protrusion 410 is inserted into the second protrusion 120 to fix the protective cover 400 and the box 100. The second protrusion 120 surrounds the opening of the through groove 110, which means that the projection of the through groove 110 on the side wall of the box 100 is located inside the closed body formed by the projection of the second protrusion 120 on the side wall of the box 100, resulting in a better sealing effect. The sealing ring is set between the third protrusion 410 and the second protrusion 120 to reduce the seepage of moisture into the box 100 and improve the sealing performance of the box 100.

[0050] The remaining working principles of this embodiment are the same as those of Embodiment 2.
