Description

Technical Field

[0001] The present application relates to the field of distribution boxes, and in particular to a low-voltage integrated distribution box that is convenient for inspection and maintenance. Background Art

[0002] In low-voltage circuits, electrical components are usually installed in distribution boxes to facilitate inspection and maintenance.

[0003] When configuring the distribution box, since the distribution box is not installed on the wall, electricians can install electrical components and connect lines from all angles. At the same time, since the distribution box includes a box shell and a mounting plate, the electrical components are installed on the mounting plate, and the mounting plate can be removed from the box shell to install the electrical components, making the overall installation more convenient.

[0004] However, when the box shell is installed on a wall or a column and the mounting plate is fixed in the box shell, subsequent repair and maintenance requires the head to be inserted into the box shell to observe the electrical components on the mounting plate. While observation is difficult, a flashlight is also required due to the dim light inside the box shell, further compressing the operating space inside the box shell.

[0005] Furthermore, during maintenance, since the box shell and the mounting plate are already fixed, maintenance personnel need to perform maintenance on the electrical components and circuits in the narrow box shell, which further increases the difficulty of maintenance. Summary of the invention

[0006] In order to solve the problem that the internal space of a traditional distribution box is small and it is inconvenient to repair and maintain the electrical components and lines in the distribution box, the present application provides a low-voltage integrated distribution box that is convenient for inspection and maintenance.

[0009] Through the above technical solution, when performing maintenance, first loosen the fixing device to slide the mounting plate to the mounting opening, and at the same time, slide the wire take-up frame out of the avoidance opening, and avoid the incoming and outgoing wires through the avoidance opening to avoid the interference of the incoming and outgoing wires on the maintenance room of the mounting plate. Then, after re-fixing the mounting frame through the fixing device, the circuits and electrical components on the mounting plate can be inspected and maintained at the mounting opening. Since the circuits and electrical components on the mounting plate are exposed to the outside world and there is no interference from the incoming and outgoing wires, the overall maintenance is more convenient.

[0010] Optionally, the avoidance opening is opened on the side wall at the top corner of the box body, and the wire take-up frame includes a bottom plate, which is bent and embedded in the avoidance opening. A wire take-up tube is installed on the horizontal end of the bottom plate, and the wire take-up tube penetrates the bottom plate. The inlet and outlet wires inside the box body pass through the wire take-up tube, and the bottom plate is slidably installed on the box body.

[0011] Optionally, a rack is provided on the base plate, and the rack is arranged along the sliding direction of the base plate. A transmission gear is rotatably installed on the box body, and the rack is meshed with the transmission gear. A push rod is rotatably installed in the box body, and the push rod is used to push the mounting frame to slide. The push rod and the transmission gear are connected via a bevel gear transmission.

[0012] Optionally, a connecting component is provided on one end of the push rod used to push the mounting frame, and the connecting component is slidingly connected to the mounting frame.

[0013] Optionally, the connecting assembly includes circular connecting blocks arranged on opposite side walls of the pushing end of the push rod, and a connecting groove is opened on the mounting frame, and the connecting block is slidably installed in the connecting groove.

[0014] Optionally, the fixing device includes a first limit plate, a second limit plate and a push rod installed on the push rod, the connecting block is arranged on the push rod, the mounting frame is provided with a first connecting hole and a second connecting hole, the first connecting hole is connected with the connecting groove, when the mounting plate is located in the box body for normal use, the first limit plate slides through the first connecting hole and abuts against the lower side of the connecting block, the mounting frame is also provided with a fixing groove, the second connecting hole is connected with the fixing groove, when the push rod is rotated to horizontal, the push rod is located in the fixing groove, the second limit plate passes through the second connecting hole and fits with the side wall of the push rod to limit the rotation of the push rod and the push rod.

[0015] Optionally, a bracket for installing the first limit plate and the second limit plate is slidably installed on the mounting frame, and a spring is arranged between the bracket and the mounting frame, and the two ends of the spring are respectively pressed against the bracket and the mounting frame, and the spring pushes the bracket to slide until the first limit plate passes through the first connecting hole and is located in the connecting groove, and the second limit plate passes through the second connecting hole and is located in the fixed groove.

[0016] Optionally, with the normal installation direction of the box body as the vertical direction, the rotation axis of the push rod is horizontal, and a mounting rod is vertically slidably installed on the mounting frame. Two baffles are arranged on the mounting rod, and the two baffles extend to above the first connecting hole and the second connecting hole respectively. When the push rod slides downward, the two baffles close the first connecting hole and the second connecting hole respectively. A control component is also arranged on the mounting frame to control the sliding of the mounting rod.

[0017] Optionally, the control assembly includes a top plate rotatably installed in the fixed groove, a control rod slidably installed on the mounting frame, and a connecting rod for connecting the control rod and the mounting rod, the lower end of the control rod slides through the mounting frame and presses against one end of the top plate, and the other end of the top plate is located directly below the top rod, when the top rod is located in the fixed groove, the top rod presses against the other end of the top plate, the top plate pushes the control rod and the mounting rod to rise, and the baffle opens the first connecting hole and the second connecting hole, and when the mounting plate is in a state of being initially fixed in the box, the connecting rod presses against the top wall of the top rod, and at this time the baffle also opens the first connecting hole and the second connecting hole.

[0018] Optionally, a rounded corner is provided at a top corner of one end of the push rod for pushing the connecting rod.

[0019] To summarize, the present application achieves a sliding installation of the mounting plate for mounting electrical components in the box body. When maintenance is needed, the mounting plate can be slid from the inside of the box body to the mounting opening for maintenance. Since it will not be disturbed by the box body during maintenance, maintenance is more convenient. At the same time, when the mounting plate slides to the mounting opening, the push rod is horizontal and the top rod is located in the fixed groove. The top plate slides into the fixed groove and fits with the side wall of the top rod to limit the top rod, so that the push rod stops rotating and the mounting plate and the bottom plate are fixed at the same time, so that the top plate does not retreat during maintenance. At this time, when the bottom plate is pushed, since the push rod stops rotating and the bottom plate is also fixed, it is not easy for the mounting frame and the mounting plate to retreat and interfere with maintenance due to pushing the bottom plate by mistake.

[0031] The following is combined with Figure 1-9 This application is described in further detail.

[0032] The present application embodiment discloses a low-voltage integrated distribution box that is convenient for inspection and maintenance. Figure 1 , Figure 2 and Figure 3, comprising a rectangular box 1, a mounting frame 2 slidably mounted in the box 1, a mounting plate 11 fixedly mounted on the mounting frame 2 for mounting electrical components and circuits, a fixing device 5 for fixing the mounting frame 2, a wire take-up frame 3 slidably mounted in the box 1, and an avoidance opening 13 opened at the lower top corner of the box 1.

[0033] Reference Figure 2 and Figure 3 The mounting plate 11 is installed vertically, and the wire take-up frame 3 includes an L-shaped bottom plate 31 and a wire take-up tube 32 installed on the bottom plate 31. The bottom plate 31 is slidably installed on the box body 1 at the avoidance opening 13. The wire take-up tube 32 penetrates the bottom plate 31, and the incoming and outgoing wires in the box body 1 enter and exit the box body 1 through the wire take-up tube 32. When the wire take-up tube 32 works normally, the bottom plate 31 closes the avoidance opening 13, and at this time, the two surfaces of the bottom plate 31 are flush with the side wall and the bottom wall of the box body 1 respectively.

[0034] Reference Figure 4 and Figure 5 A rack 33 is fixedly mounted on the bottom wall of the bottom plate 31 , and the length direction of the rack 33 is arranged along the sliding direction of the bottom plate 31 . A transmission gear 14 is rotatably mounted on the bottom wall of the box body 1 , and the transmission gear 14 is meshed with the rack 33 .

[0035] Reference Figure 4 and Figure 6 Two push rods 15 are arranged between the back plate of the box body 1 and the mounting frame 2. In the initial state, the push rods 15 are vertical, and the lower ends of the push rods 15 are rotatably mounted on the box body 1. The rotation axes of the push rods 15 are coaxial and horizontal with each other. The two push rods 15 are fixedly connected by a rod to achieve synchronous rotation.

[0036] Reference Figure 4 and Figure 5 The transmission gear 14 is connected to a push rod 15 at a relatively close distance through a bevel gear. When the bottom plate 31 slides out of the avoidance opening 13, the rack 33 drives the transmission gear 14 to rotate, and then drives the push rod 15 to rotate through the bevel gear to push out the mounting frame 2 and the mounting plate 11. When the wire take-up tube 32 on the bottom plate 31 slides through the avoidance opening 13, the mounting plate 11 slides to the avoidance opening 13, and the wire take-up tube 32 and the mounting plate 11 are staggered with each other.

[0037] Reference Figure 5 and Figure 7 , refer to Figure 4 and Figure 5The fixing device 5 includes a bracket 6 which is horizontally slidably mounted on the mounting frame 2, a first limit plate 51 and a second limit plate 52 which are fixedly mounted on the bracket 6, and a push rod 53. The sliding direction of the bracket 6 is parallel to the rotation axis of the push rod 15. The push rod 53 is integrally arranged on the top wall of the push rod 15, and the push rod 53 is perpendicular to the push rod 15. A vertical slide groove 21 is provided on the mounting frame 2. The end face of one end of the push rod 53 is semicircular and slidably mounted in the slide groove 21. At the same time, the semicircular end of the push rod 53 is pressed against the bottom of the slide groove 21. After the push rod 15 is rotated, the mounting frame 2 is pushed out by pressing the push rod 53 against the bottom of the slide groove 21.

[0038] Reference Figure 5 and Figure 7 A connecting assembly 4 is also provided on the push rod 15 to form a sliding connection between the push rod 15 and the mounting frame 2, so that when the push rod 15 is reversed, the mounting frame 2 and the mounting plate 11 can be slidably brought back to the inside of the box body 1. The connecting assembly 4 includes two circular connecting blocks 41, and the two connecting blocks 41 are coaxially fixedly installed on the two side walls of the top rod 53. A connecting groove 22 is provided on the opposite side walls of the slide groove 21, and the connecting groove 22 is vertical. The two connecting blocks 41 are slidably installed in the two slide grooves 21 respectively.

[0039] Reference Figure 5 and Figure 7 A first connecting hole 23 and a second connecting hole 24 are provided on the mounting frame 2. The first connecting hole 23 is connected to the connecting groove 22. When the push rod 15 is vertical, one end of the push rod 53 is located in the slide groove 21, and the connecting block 41 is pressed against the upper end surface of the connecting groove 22. The first limiting plate 51 slides through the first connecting hole 23 and is located in the connecting groove 22. The lower side wall of the connecting block 41 is pressed against the top wall of the first limiting plate 51, so that the connecting block 41 is fixed in the connecting groove 22, thereby fixing the mounting frame 2, the mounting plate 11 and the bottom plate 31.

[0040] Reference Figure 8 and Fig. 9 A fixing groove 25 is provided at the bottom of the mounting frame 2. When the push rod 15 rotates to a horizontal position, the top rod 53 and the connecting block 41 are both located in the fixing groove 25. At this time, the top rod 53 is vertical. After the second limiting plate 52 slides through the second connecting hole 24, it fits with the top wall of the top rod 53 when it is horizontal to limit the rotation of the top rod 53 and the push rod 15. At this time, since the push rod 15 stops rotating, the mounting plate 11 and the bottom plate 31, which are interconnected as a whole, are fixed.

[0041] Reference Figure 8 and Fig. 9When the second limiting plate 52 slides into the fixing groove 25, the second limiting plate 52 fits against the inner wall of the fixing groove 25, so that the top rod 53 is pressed against the inner wall of the fixing groove 25 through the second limiting plate 52, further improving the stability after fixation.

[0042] A spring 61 is arranged between the mounting frame 2 and the bracket 6, and the two ends of the spring 61 are fixedly connected to the bracket 6 and the mounting frame 2 respectively, and a support rod 26 is fixedly installed on the mounting frame 2, and the support rod 26 coaxially passes through the spring 61 and slides through the bracket 6, and the spring 61 is supported by the support rod 26, and the support rod 26 also limits the sliding of the bracket 6.

[0043] Reference Figure 8 and Fig. 9 Under normal conditions, the spring 61 pushes the bracket 6 to slide until the first limit plate 51 is located in the connection slot 22 and the second limit plate 52 is located in the fixed slot 25. A mounting rod 7 is also vertically slidably mounted on the mounting frame 2, and two baffles 71 are fixedly mounted on the mounting rod 7. The two baffles 71 are respectively located directly above the first connection hole 23 and the second connection hole 24. After the mounting rod 7 slides vertically downward, the two baffles 71 respectively block the first connection hole 23 and the second connection hole 24. When the push rod 15 is rotating, the baffle 71 slides to cover the first connecting hole 23 and the second connecting hole 24, so that the push rod 15 can smoothly rotate to horizontal or vertical, and the top rod 53 can smoothly enter the fixing groove 25, and then the baffle 71 slides up to open the first connecting hole 23 or the second connecting hole 24. Under the push of the spring 61, the bracket 6 slides to push the first limit plate 51 and the second limit plate 52 to slide into the connecting groove 22 and the fixing groove 25 respectively to fix the push rod 15.

[0044] Reference Figure 8 and Fig. 9 Meanwhile, a control assembly 8 is also provided on the mounting frame 2 for controlling the sliding movement of the mounting rod 7. The control assembly 8 includes a control rod 82 vertically slidably mounted on the mounting frame 2 and a top plate 81 rotatably mounted in the fixing groove 25. The lower end of the control rod 82 slides through the mounting frame 2 and abuts against one end of the top plate 81. The control rod 82 is fixedly connected to the mounting rod 7 through a connecting rod 83.

[0045] Reference Figure 8 and Fig. 9Under normal circumstances, under the action of gravity, the lower end of the control rod 82 presses down one end of the top plate 81. At this time, the baffle 71 blocks the first connecting hole 23 and the second connecting hole 24. The other end of the top plate 81 is located directly below the end of the top rod 53 that is pressed against the bottom of the slide groove 21. When the top rod 53 enters the fixing groove 25 and is vertical, the top rod 53 presses against the top plate 81 to rotate, and then pushes the control rod 82 and the mounting rod 7 to slide up through the top plate 81, thereby driving the baffle 71 to open the first connecting hole 23 and the second connecting hole 24.

[0046] At the same time, when the push rod 15 is vertical, the connecting rod 83 is in close contact with the top wall of the push rod 53, and the baffle 71 also opens the first connecting hole 23 and the second connecting hole 24.

[0047] Reference Figure 3 At the same time, a pull rod 62 is fixedly installed on the bracket 6, and one end of the pull rod 62 is bent and extended to the front side of the mounting plate 11, and the bracket 6 is pulled by the pull rod 62 to slide.

[0048] The implementation principle of a low-voltage integrated distribution box that is convenient for inspection and maintenance in an embodiment of the present application is as follows: when maintenance is required, first pull the bracket 6 through the pull rod 62 to make the first limit plate 51 leave the connecting groove 22, then pull the mounting plate 11 to slide one end distance through the pull rod 62, and then release the pull rod 62, and pull the bottom plate 31 to slide and drive the mounting plate 11 to slide to the mounting port 12 until a collision sound is heard, at this time, the top rod 53 pushes the top plate 81 to rotate and drive the baffle 71 to open the second connecting hole 24, and the second limit plate 52 slides into the fixing groove 25 to fix the top rod 53 and the push rod 15, and maintenance can be carried out.

[0049] After the maintenance is completed, the second limit plate 52 is pulled out of the fixing groove 25 by the pull rod 62, and the mounting plate 11 is pushed back to the initial position until a collision sound is heard. At this time, the push rod 53 pushes the baffle 71 through the connecting rod 83 to open the first limit hole, and the first limit plate 51 passes through the first connecting hole 23 and slides into the connecting groove 22.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
