Description

Technical Field

[0001] This utility model relates to the field of junction box technology, and in particular to a support structure for a junction box. Background Technology

[0002] A junction box is an electrical connection device that plays a vital role in a circuit system. It is mainly used to centralize, branch, connect, protect, and manage multiple wires or cables, making the connections between wires more stable, safe, and reliable. By using junction boxes properly, safety hazards such as poor contact, short circuits, and leakage that may result from direct wire connections can be effectively avoided. At the same time, it can make the wiring layout neater and more aesthetically pleasing, facilitate maintenance and repair, and improve the stability and operability of the entire circuit system. It is an indispensable basic component in modern electrical systems.

[0003] In existing technologies, plugs are typically inserted into junction boxes to achieve electrical connections. However, when the plug is inserted into the junction box, the stability is generally poor, as the plug is prone to falling out of the junction box, which reduces the stability of the connection.

[0004] An existing patent (publication number: CN222749803U) discloses a reinforcement structure for connecting and fixing a plug to a junction box, belonging to the field of reinforcement structure technology. It includes a junction box body and a plug body. The plug body is slidably inserted into the upper surface of the junction box body. In this reinforcement structure, the left and right spring telescopic rods are compressed, causing the left and right sliding cylinders to move in opposite directions outside the left and right sliding rods, and causing the left and right locking pins to move into the interior of the left and right support frames. At this time, the plug body can be inserted into the upper surface of the junction box body, and the opposite side of the left and right support frames is in contact with the left and right sides of the plug body. Then, the left and right toggle plates are released, the left and right spring telescopic rods are reset, and the left and right locking pins slide into the interior of the left and right locking slots. This fixes the plug body to the upper surface of the junction box body, improving the stability of the connection between the plug and the junction box.

[0005] To address the aforementioned issues, existing patents offer solutions. However, existing junction boxes often lack flexibility in adjusting the support angle during installation, making it difficult to precisely fit the mounting surface. This results in inconvenient installation and poor stability. Furthermore, the lack of effective vibration damping measures makes it easy to affect wiring stability in vibrating environments, hindering the long-term reliable operation of the support structure.

[0006] Therefore, a support structure for junction boxes is proposed. Utility Model Content

[0007] The purpose of this utility model is to provide a support structure for junction boxes that can solve the problems of existing junction boxes, such as difficulty in flexibly adjusting the support angle during installation, inconvenience in accurately fitting the mounting surface, poor stability, lack of effective shock absorption measures, easy impact on wiring stability in vibration environment, and difficulty in ensuring long-term reliable operation of the support structure.

[0008] To achieve the above objectives, this utility model provides the following technical solution: a support structure for a junction box, including a box body, a mounting bracket bolted to the rear side of the box body, a support mechanism inserted into the inner wall of the mounting bracket, a pre-installed plate rotatably connected to the surface of the support mechanism, a rubber pad provided on the rear side of the pre-installed plate, a wiring assembly provided on the left side of the box body, and a wire harness block provided on the left side of the box body.

[0009] The support mechanism includes a rotating block, a rotating shaft, and an insert block. The rear side of the insert block is bolted to the front side of the rotating shaft, and the rear side of the rotating shaft is bolted to the front side of the rotating block. The surface of the rotating block is rotatably connected to the inner wall of the pre-installed plate, and the surface of the insert block is inserted into the inner wall of the mounting bracket.

[0010] Preferably, a fixing pad is provided on the front side of the rubber pad, and the surface of the fixing pad is inserted into the inner wall of the pre-assembled plate.

[0011] Preferably, the inner wall of the pre-mounted plate is provided with a rotating hole for use with the rotating block, and the inner wall of the pre-mounted plate is provided with a movable hole for use with the rotating shaft.

[0012] Preferably, the front side of the rubber pad is in close contact with the rear side of the pre-installed plate, and the inner wall of the pre-installed plate is provided with a fixing groove for use with the fixing pad.

[0013] Preferably, the inner wall of the pre-installed plate is movably connected to a buffer sleeve, and the inner wall of the buffer sleeve is movably connected to a pre-installed bolt.

[0014] Preferably, the inner wall of the pre-installed plate is provided with an adjustment groove, and the inner wall of the mounting bracket is provided with a slot for use with the insert block.

[0015] Preferably, a fixing plate is bolted to the left side of the box body, and a connecting bracket is bolted to the left side of the fixing plate.

[0016] Preferably, a limiting frame is bolted to the rear side of the wire harness block, and the surface of the limiting frame is inserted into the inner wall of the connecting frame.

[0028] Please see Figure 1-6 The present invention provides the following technical solution:

[0029] A support structure for a junction box includes a box body 1, a mounting bracket 3 bolted to the rear side of the box body 1, a support mechanism 2 inserted into the inner wall of the mounting bracket 3, a pre-installed plate 4 rotatably connected to the surface of the support mechanism 2, a rubber pad 5 provided on the rear side of the pre-installed plate 4, a wiring assembly 6 provided on the left side of the box body 1, and a wire harness block 7 provided on the left side of the box body 1.

[0030] The support mechanism 2 includes a rotating block 203, a rotating shaft 202, and an insert block 201. The rear side of the insert block 201 is bolted to the front side of the rotating shaft 202, the rear side of the rotating shaft 202 is bolted to the front side of the rotating block 203, the surface of the rotating block 203 is rotatably connected to the inner wall of the pre-installed plate 4, and the surface of the insert block 201 is inserted into the inner wall of the mounting bracket 3.

[0031] In this embodiment: By setting up a support mechanism 2, the position of the rotating block 203 and the rotating shaft 202 are fixed during use, and the position of the rotating shaft 202 and the insertion block 201 are fixed. This facilitates the subsequent insertion of the insertion block 201 into the inner wall of the mounting bracket 3 by the pre-installed plate 4, which facilitates the installation of the pre-installed plate 4. This allows the pre-installed plate 4 to be flexibly adjusted in angle and positioned according to actual installation needs, making it easy to fit with the wall or other mounting surfaces, improving the convenience and accuracy of installation. At the same time, it enhances the stability of the connection between the support structure and the mounting surface. By setting up a rubber pad 5 and a cable tie block 7, the rubber pad 5 on the back of the pre-installed plate 4 can effectively buffer vibration and reduce the impact of external vibration on the internal electrical connection of the box 1, ensuring the stability of the wiring. The cable tie block 7 is set on the left side of the box 1, which can prevent the external cables from bending when connecting through the wiring assembly 6, thus ensuring the stable connection of the cables.

[0032] Specifically, such as Figure 3 As shown, a fixing pad 8 is provided on the front side of the rubber pad 5, and the surface of the fixing pad 8 is inserted into the inner wall of the pre-installed plate 4.

[0033] Specifically, such as Figure 5 As shown, the inner wall of the pre-mounted plate 4 is provided with a rotating hole 9 for use with the rotating block 203, and the inner wall of the pre-mounted plate 4 is provided with a movable hole 10 for use with the rotating shaft 202.

[0034] Specifically, such as Figure 3 As shown, the front side of the rubber pad 5 is in close contact with the rear side of the pre-installed plate 4, and the inner wall of the pre-installed plate 4 is provided with a fixing groove 11 that is used in conjunction with the fixing pad 8.

[0035] In this embodiment: By setting a fixing pad 8, the fixing pad 8 is fixed to the rubber pad 5 during use, which facilitates the subsequent installation of the fixing pad 8 on the inner wall of the pre-installed plate 4 by the rubber pad 5, and facilitates the stable cushioning function of the rubber pad 5. The rotating hole 9 opened in the inner wall of the pre-installed plate 4 facilitates the rotation of the rotating block 203 on the inner wall of the pre-installed plate 4 through the rotating hole 9. The movable hole 10 opened in the inner wall of the pre-installed plate 4 facilitates the rotation of the rotating shaft 202 on the inner wall of the pre-installed plate 4 through the movable hole 10, which facilitates the flexible adjustment of the fixing angle of the pre-installed plate 4. The fixing groove 11 opened in the inner wall of the pre-installed plate 4 facilitates the installation of the fixing pad 8 on the inner wall of the pre-installed plate 4 through the fixing groove 11, which facilitates the stable installation of the rubber pad 5 and facilitates the use by the user.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, a buffer sleeve 12 is movably connected to the inner wall of the pre-installed plate 4, and a pre-installed bolt 13 is movably connected to the inner wall of the buffer sleeve 12.

[0037] Specifically, such as Figure 2 As shown, the inner wall of the pre-installed plate 4 is provided with an adjustment groove 14, and the inner wall of the mounting bracket 3 is provided with a slot 15 for use with the insert block 201.

[0038] In this embodiment: by setting a buffer sleeve 12 and a pre-installed bolt 13, the buffer sleeve 12 is installed on the inner wall of the pre-installed plate 4 during use. Then, the pre-installed bolt 13 is rotated on the inner wall of the buffer sleeve 12 and the pre-installed plate 4, which makes it easy to restrict the position of the pre-installed plate 4 by the pre-installed bolt 13. The pre-installed bolt 13 can be installed and buffered by the buffer sleeve 12 to avoid vibration during connection and use. The adjustment groove 14 opened on the inner wall of the pre-installed plate 4 makes it easy for the buffer sleeve 12 to adjust the installation position of the pre-installed bolt 13 by adjusting the groove 14. The slot 15 opened on the inner wall of the mounting bracket 3 makes it easy for the insert block 201 to be inserted into the inner wall of the mounting bracket 3 by slot 15.

[0039] Specifically, such as Figure 6 As shown, a fixing plate 16 is bolted to the left side of the box 1, and a connecting bracket 17 is bolted to the left side of the fixing plate 16.

[0040] Specifically, such as Figure 6 As shown, a limit bracket 18 is bolted to the rear side of the cable bundle 7, and the surface of the limit bracket 18 is inserted into the inner wall of the connecting bracket 17.

During use, the positions of the rotating block 203 and the rotating shaft 202 are fixed, and the positions of the rotating shaft 202 and the insertion block 201 are fixed. This facilitates the subsequent insertion of the insertion block 201 into the inner wall of the mounting bracket 3 via the pre-installed plate 4, thus completing the installation of the pre-installed plate 4. This allows the pre-installed plate 4 to be flexibly adjusted in angle and positioned according to actual installation needs, facilitating its fit with wall surfaces and other mounting surfaces, improving installation convenience and accuracy. It also enhances the stability of the connection between the support structure and the mounting surface. (The last sentence appears to be incomplete and possibly refers to a separate process involving rubber bushings.) Rubber pad 5 and cable tie block 7 are provided on the back side of the pre-installed plate 4. Rubber pad 5 can effectively buffer vibration and reduce the impact of external vibration on the internal electrical connection of the box 1, ensuring the stability of the wiring. The left side of the box 1 is provided with a fixing plate 16 and a connecting bracket 17. The limiting bracket 18 on the back side of the cable tie block 7 is inserted into the inner wall of the connecting bracket 17 to stabilize the position of the cable tie block 7. This allows the cable tie block 7 to more reliably restrain the cable and prevent the cable from shaking or shifting, further ensuring the stability of the cable connection.
