Description

Technical Field

[0001] This utility model belongs to the technical field of low-voltage junction boxes, and particularly relates to a low-voltage junction box that is easy to maintain. Background Technology

[0002] In low-voltage power distribution systems, low-voltage junction boxes play a crucial role, distributing power from the main lines to various branch lines to supply power to different areas or equipment. With the acceleration of urbanization and the continuous growth of electricity demand, the scale and complexity of low-voltage power distribution systems are increasing, placing higher demands on the performance and reliability of low-voltage junction boxes.

[0003] An existing patent (publication number: CN218275981U) discloses a low-voltage cable distribution box, relating to the field of distribution box technology. It includes a box body and a cover rotatably mounted on the box body, and further includes a cable tray fixedly mounted inside the box body. Multiple first arc-shaped clamps are slidably disposed on the cable tray, and a second arc-shaped clamp is slidably disposed on each of the first arc-shaped clamps. Multiple elastic elements are disposed between the second arc-shaped clamps and the first arc-shaped clamps. This utility model provides a low-voltage cable distribution box that, by using the first and second arc-shaped clamps to clamp and straighten the cables, achieves the effect of organizing multiple cables within the box.

[0004] Existing low-voltage distribution boxes often neglect wiring management issues during use. The internal wiring lacks proper zoning and labeling, making it difficult to clearly identify the wiring routes and connections. When performing line maintenance, capacity expansion, or troubleshooting, staff need to spend a lot of time and energy sorting out the wiring, which not only reduces work efficiency but also easily leads to safety accidents due to misoperation. Therefore, a low-voltage distribution box that is easy to maintain is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a low-voltage distribution box that is easy to maintain. It has the advantages of being able to distinguish and constrain wire harnesses while facilitating operators to inspect and maintain the inside of the box. This solves the problem mentioned in the aforementioned comparative documents that the routing and connection relationships of the lines are difficult to clearly identify. When performing line maintenance, capacity expansion, or troubleshooting, staff need to spend a lot of time and energy sorting out the lines, which not only reduces work efficiency but also easily leads to safety accidents due to misoperation.

[0006] To achieve the above objectives, this application provides the following technical solution: a low-voltage distribution box that is easy to maintain, comprising a box body, a side sliding groove provided on the inner wall of the box body, a lifting mechanism sliding on the inner wall of the side sliding groove, a support assembly internally threaded to the lifting mechanism, an elastic clamping mechanism fixedly connected to the inner wall of the support assembly, an adjusting screw internally threaded to the lifting mechanism, a mounting bracket fixedly installed on the inner wall of the box body, and a door hinged to the outer surface of the box body. The lifting mechanism is provided in two sets, and the support assembly is provided in several sets.

[0007] The above solution uses an adjusting screw to support the lifting mechanism within the enclosure, along with a side sliding groove. After electrical components are mounted on the mounting bracket, the supporting components on the lifting mechanism, combined with an elastic clamping mechanism, can clamp and constrain the wire harnesses on the same electrical component. Multiple supporting components and elastic clamping mechanisms can clamp and position wire harnesses at different locations, effectively isolating and distinguishing them. When cable maintenance is required, pushing the elastic clamping mechanism to allow it to spring back releases the constraint on the wire harness, and the lateral support position remains unchanged after reset. Simultaneously, the adjusting screw drives the lifting mechanism to raise and lower the supporting components to avoid obstructing the position of electrical components. This combination allows for the differentiation and constraint of wire harnesses while facilitating maintenance and repair of the enclosure's interior by operators.

[0008] Furthermore, the lifting mechanism includes a lifting plate, a side slider is fixedly installed on the back of the lifting plate, the side slider is slidably connected to the inner wall of the side sliding groove, and the drive adjustment screw passes through the interior of the lifting plate and is threadedly connected to it.

[0009] The above scheme allows the lifting plate to move longitudinally by rotating the adjusting screw, while the side slider restricts its sliding displacement within the side groove, thus providing lifting driving force for the support component and the elastic clamping mechanism.

[0010] Furthermore, the lifting mechanism has a crossbar internally threadedly connected to it, one end of which is fixedly connected to a limiting slide plate. The limiting slide plate is slidably connected to the inside of the side slide groove. There are two crossbars, and the ends of both crossbars are threadedly connected to the limiting slide plate.

[0011] The above scheme uses a crossbar positioned between the lifting plate and the limiting slide plate to provide lateral support for multiple support components inside the housing. When the lifting plate moves, the limiting slide plate at the end of the crossbar slides within the side groove on the other side to provide stable and movable support for the support components.

[0012] Furthermore, the support assembly includes a support plate, with sleeve plates fixedly connected to the top and bottom of the support plate. The sleeve plates pass through the outside of the crossbar and are symmetrically arranged on the crossbar. A sliding rod is threadedly connected to the outer surface of the support plate, and the bottom of the elastic clamping mechanism is slidably connected to the outside of the sliding rod.

[0013] The above solution connects the sleeve plate to the crossbar, allowing the support plate to rest on the crossbar. This enables the cable to be elastically clamped and positioned by the elastic clamping mechanism on the front side of the electrical component, thus providing positioning support for the connected cable.

[0014] Furthermore, the elastic clamping mechanism includes a fixed plate, a spring telescopic rod is fixedly connected to the outer surface of the fixed plate, a clamping sleeve is fixedly installed at one end of the spring telescopic rod, and a number of support plates are provided, with the spring telescopic rod and clamping sleeve symmetrically arranged between two support plates.

[0015] With the above solution, after the wire harness is bundled together, it is passed through the inside of the clamping sleeve, and the spring telescopic rod is released to reset it, so that both sets of clamping sleeves surround the outside of the wire harness to form a positioning clamping effect on the wire harness. In addition, the support plate blocks each set of wire harnesses to form a distinct constraint on the wire harnesses.

[0016] Furthermore, a sliding sleeve is fixedly installed at the bottom of the clamping sleeve, and the sliding sleeve extends through to the outside of the sliding rod and is slidably connected to it.

[0017] The above solution uses a sliding sleeve that penetrates the outside of the sliding rod to provide rigid support at the bottom of the clamping sleeve. This allows the spring telescopic rod to only undergo lateral elastic deformation, thus providing better pre-constraint and quick release of the constraint on the wire harness.

[0018] Furthermore, a limiting support rod is provided inside the housing, which extends through the interior of the limiting slide plate and is slidably connected thereto.

[0019] The above solution increases the connection and support strength of the limiting slide plate by passing through the limiting support rod, while limiting its movement path to prevent instability during movement.

[0020] Furthermore, a horizontal support plate is fixedly installed inside the box.

[0021] With the above solution, the horizontal support plate is supported at the bottom of the adjusting screw and the limiting rod, which facilitates stable support during internal displacement of the housing.

[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0023] This easy-to-maintain low-voltage junction box uses an adjusting screw that passes through a lifting mechanism and is supported inside the box via a side sliding groove. After electrical components are installed on the mounting bracket, the support components on the lifting mechanism, along with the elastic clamping mechanism, can clamp and constrain the wire harnesses on the same electrical component. Multiple sets of support components and elastic clamping mechanisms can clamp and position wire harnesses at different locations, achieving a blocking and differentiation effect. When cable maintenance is required, pushing the elastic clamping mechanism to make it spring back releases the constraint on the wire harness, and the lateral support position does not change after reset. At the same time, the adjusting screw can drive the lifting mechanism to raise and lower the support components to avoid obstructing the position of electrical components. Thus, it can differentiate and constrain wire harnesses while facilitating maintenance and repair of the box interior by operators. Attached Figure Description

[0030] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0031] Please see Figure 1 and Figure 2This embodiment provides a low-voltage distribution box that is easy to maintain. It includes a box body 1, with a side sliding groove 2 on the inner wall of the box body 1. A lifting mechanism 3 slides along the inner wall of the side sliding groove 2. A support assembly 4 is threadedly connected to the inside of the lifting mechanism 3. An elastic clamping mechanism 5 is fixedly connected to the inner wall of the support assembly 4. An adjusting screw 6 is threadedly connected to the inside of the lifting mechanism 3. A mounting bracket 7 is fixedly installed on the inner wall of the box body 1. A door 8 is hinged to the outer surface of the box body 1. Two sets of lifting mechanisms 3 are provided, and several sets of support assemblies 4 are provided. The adjusting screw 6 passes through the lifting mechanism 3 and, in conjunction with the side sliding groove 2, supports it inside the box body 1. When electrical components are installed on the mounting bracket 7, the... The support component 4 on the lifting mechanism 3, together with the elastic clamping mechanism 5, can clamp and constrain the wire harness on the same electrical component. With multiple sets of support components 4 and elastic clamping mechanisms 5, wire harnesses at different positions can be clamped and positioned to achieve the effect of blocking and distinguishing them. When it is necessary to inspect and repair the cable, the constraint on the wire harness can be released by pushing the elastic clamping mechanism 5 to make it spring back. The lateral support position will not change after the reset. At the same time, with the adjustment screw 6, the lifting mechanism 3 can be driven to lift and lower the support component 4 to avoid blocking the position of the electrical component. Thus, the wire harness can be distinguished and constrained while facilitating the operator to inspect and maintain the inside of the box 1.

[0032] Please see Figure 3 , Figure 4 and Figure 5 The lifting mechanism 3 includes a lifting plate 301. A side slider 302 is fixedly installed on the back of the lifting plate 301. The side slider 302 is slidably connected to the inner wall of the side slide groove 2. A drive adjusting screw 6 passes through the interior of the lifting plate 301 and is threadedly connected to it. A crossbar 303 is threadedly connected inside the lifting mechanism 3. One end of the crossbar 303 is fixedly connected to a limiting slide plate 304. The limiting slide plate 304 is slidably connected to the interior of the side slide groove 2. There are two crossbars 303, and the ends of both crossbars 303 are threadedly connected to the limiting slide plate 304. By rotating the adjusting screw 6, the lifting plate 301 can be driven to move in the longitudinal direction, which, in conjunction with the side slider 302, restricts the sliding displacement within the side slide groove 2, providing lifting driving force for the support assembly 4 and the elastic clamping mechanism 5. By placing the crossbar 303 between the lifting plate 301 and the limiting slide plate 304... The lifting plate 301 is used to provide lateral support for multiple sets of support components 4 inside the housing 1. When the lifting plate 301 moves, the limiting slide plate 304 at the end of the crossbar 303 slides inside the side slide groove 2 on the other side to provide stable support and moving support for the support components 4.

[0033] Please see Figure 2 , Figure 3 and Figure 4The support assembly 4 includes a support plate 401. A sleeve plate 402 is fixedly connected to the top and bottom of the support plate 401. The sleeve plate 402 passes through the outside of the crossbar 303 and is symmetrically arranged on the crossbar 303. A slide rod 403 is threadedly connected to the outer surface of the support plate 401. The bottom of the elastic clamping mechanism 5 is slidably connected to the outside of the slide rod 403. By connecting the sleeve plate 402 to the crossbar 303, the support plate 401 is supported on the crossbar 303. In this way, the elastic clamping mechanism 5 can be used to elastically clamp and position the cable on the front side of the electrical component in conjunction with the inner side of the elastic clamping mechanism 5, thus providing a positioning support effect for the connected cable.

[0034] Please see Figure 3 , Figure 4 and Figure 5 The elastic clamping mechanism 5 includes a fixed plate 501, a spring telescopic rod 502 fixedly connected to the outer surface of the fixed plate 501, a clamping sleeve 503 fixedly installed at one end of the spring telescopic rod 502, and several support plates 401. The spring telescopic rods 502 and clamping sleeves 503 are symmetrically arranged between pairs of support plates 401. A sliding sleeve 504 is fixedly installed at the bottom of the clamping sleeve 503. The sliding sleeve 504 passes through the outside of the sliding rod 403 and slides therethrough. When the wire harness is bundled together, it passes through the clamping sleeve. The inside of the sleeve 503 is opened, and the spring telescopic rod 502 is released to reset it, so that both sets of clamping sleeves 503 surround the outside of the wire harness, so as to form a positioning clamping effect on the wire harness. In conjunction with the support plate 401, each set of wire harnesses is blocked to form a distinct constraint effect on the wire harnesses. The sliding sleeve 504 passes through the outside of the sliding rod 403, so that the bottom of the clamping sleeve 503 has a rigid support function, so that the spring telescopic rod 502 can only produce lateral elastic deformation, so as to provide better constraint and quick release of constraint on the wire harness.

[0035] This embodiment provides a low-voltage junction box that is easy to maintain. By connecting the sleeve plate 402 to the crossbar 303, the support plate 401 rests on the crossbar 303. When the wire harness is bundled together, it is passed through the clamping sleeve 503, and the spring telescopic rod 502 is released to reset it. This ensures that both sets of clamping sleeves 503 surround the wire harness, providing a positioning and clamping effect. Furthermore, multiple sets of support plates 401 isolate each group of wire harnesses, creating a differentiated constraint effect. A sliding sleeve 504 passes through the outer edge of the sliding rod 403. The clamping sleeve 503 has a rigid support function at its bottom, so that the spring telescopic rod 502 can only produce lateral elastic deformation, which can play a good role in pre-constraining and quickly releasing the constraint of the wire harness. By rotating the adjusting screw 6, the lifting plate 301 can be driven to slide in the side slide groove 2 in conjunction with the side slider 302 and the limiting slide plate 304, and move in the longitudinal direction to provide lifting driving force for the support plate 401. This allows the support component 4 to be moved down as a whole when the operator inspects the internal components of the box 1, providing operating space for inspection.

[0036] The working principle of the above embodiments is as follows:

[0037] A crossbar 303 is positioned between the lifting plate 301 and the limiting slide plate 304. A sleeve plate 402 is connected to the crossbar 303, allowing the support plate 401 to rest on the crossbar 303. A sliding rod 403 passes through the interior of the two sets of sliding sleeves 504 on the support plates 401. When it is necessary to position and fix the cable harness, pushing the clamping sleeve 503 in the reverse direction causes the spring telescopic rod 502 to move in the opposite direction, opening the clamping gap. The cable harness is then passed through the clamping sleeve 503 and released, causing the two sets of clamping sleeves 503 to automatically spring back and reset, clamping the cable. Outside the bundle, the sliding sleeve 504 resets and fits against the opposite sliding sleeve 504, supporting it below the clamping sleeve 503, thus constraining the wire harness. Multiple sets of support plates 401 support each set of clamping sleeves 503 on the inside in pairs, constraining each set of wire harnesses to form a distinguishing and blocking state. When it is necessary to inspect the inside of the box 1, the adjusting screw 6 is rotated to drive the lifting plate 301 to move longitudinally, which in turn drives the support plate 401 and the clamping sleeve 503 to move longitudinally together to release the obstruction of electrical components and free up maintenance space.
