Description

Technical Field

[0001] This utility model relates to the field of cable branch box technology, specifically a cable branch box. Background Technology

[0002] A cable distribution box is a device primarily used for branching or transferring cables. Its main function is to branch a large-section cable into multiple smaller-section cables, or to transfer cables within a long cable line to meet different power supply needs. This device is widely used in the cabling process of power distribution networks, especially in urban power grids for street lighting and small-user power supply. Furthermore, with technological advancements, cable distribution boxes with switches are now available, and some even possess distribution network automation capabilities.

[0003] However, existing cable distribution boxes open by flipping the door upwards. To support the upward-flipping door, manufacturers use hydraulic support rods to facilitate operation of the internal components. However, over time, the hydraulic support rods lose hydraulic support force, causing the door to fall downwards and affecting the operator's normal operation. Summary of the Invention

[0004] The purpose of this utility model is to provide a cable branch box to solve the problem mentioned in the background art where the door of the existing cable branch box is flipped upwards when opened. In order to support the upward-flipping door, the manufacturer uses a hydraulic support rod to support the door, which facilitates the operator's operation of the internal pneumatic components of the cable branch box. However, after long-term use, the hydraulic support rod may reduce its hydraulic support force, causing the door to fall downwards, thus affecting the operator's normal operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable branch box, including a box body, an installation cavity is provided inside the box body, a box door is fixedly connected to the front surface of the box body at a position opposite to the installation cavity via a hinge, a fixing seat is fixedly connected to the inner side of the box door, a support plate is rotatably connected to the surface of the fixing seat, and a guide rod that cooperates with the support plate is fixedly connected to the inner wall of the installation cavity, and the guide rod is slidably connected to the support plate.

[0006] Preferably, the guide rod includes a fixed cylinder, a connecting rod, and a limiting member. The connecting rod is threaded onto the surface of the fixed cylinder, and the limiting member is fixedly connected to the end of the connecting rod away from the fixed cylinder.

[0007] Preferably, a rotating rod is fixedly connected to the surface of the fixed base, and a rotating hole is opened on the surface of the support plate at a position opposite to the rotating rod, and the inner wall of the rotating hole is rotatably connected to the outer wall of the rotating rod.

[0008] Preferably, the surface of the support plate is provided with a sliding groove, and the inner wall of the sliding groove is slidably connected to the outer wall of the connecting rod. The surface of the support plate is provided with a rotating position at the top of the sliding groove, and the rotating position is connected to the sliding groove.

[0009] Preferably, the support plate has multiple fixing positions arranged longitudinally on one side of the sliding groove, and the fixing positions communicate with the sliding groove, with a connecting rod movably connected within each fixing position.

[0010] Preferably, the diameter of the limiting member is greater than the width of the sliding groove, and the bottom surface of the limiting member is in contact with the surface of the support plate.

[0011] Preferably, a handle is fixedly installed at the bottom of the box door.

[0012] Beneficial effects

[0013] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0014] This invention employs a purely mechanical support structure consisting of a fixed base, a support plate, a guide rod, and multiple fixing positions on the support plate, completely replacing the easily aging hydraulic support rod. By engaging the connecting rod with different fixing positions on the support plate, rigid locking of the door can be achieved at any opening angle. The design of the limiting components and fixing positions ensures that the connecting rod is firmly restrained in the selected position, fundamentally eliminating the hidden danger of the door accidentally falling due to the weakening of the support force, thus ensuring the safety of the operator and the continuity of operation.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0025] like Figure 1-4 This is a schematic diagram of a preferred embodiment of the present invention for a cable branch box. In this embodiment, the cable branch box includes a box body 1, with an installation cavity 11 inside for installing electrical components. A door 2 is hinged to the front end of the box body 1, facing the operator, at a corresponding position in the installation cavity 11, allowing the door 2 to rotate and open around the hinge axis. A handle 21 is fixedly installed at the bottom of the door 2 for easy opening by the operator. A fixed base 3 is fixedly connected to the inside of the door 2. A rotating rod 31 is fixedly connected to the surface of the fixed base 3. A support plate 4 is elongated, with a rotating hole 44 at one end near the fixed base 3. The inner wall of the rotating hole 44 is rotatably connected to the outer wall of the rotating rod 31, allowing the support plate 4 to rotate relative to the fixed base 3 and the door 2 around the axis of the rotating rod 31. A guide rod 5 is fixedly connected to the inner wall of the installation cavity 11.

[0026] In this embodiment, the guide rod 5 specifically includes a fixed cylinder 51, a connecting rod 52, and a limiting member 53. The fixed cylinder 51 is firmly installed on the inner wall of the mounting cavity 11 by welding. One end of the connecting rod 52 is screwed into the fixed cylinder 51 via a threaded connection. By rotating the connecting rod 52, its length extending beyond the connecting rod 52 can be adjusted. The limiting member 53 is fixedly connected to the end of the connecting rod 52 away from the fixed cylinder 51. The limiting member 53 is a disc with a diameter larger than that of the connecting rod 52.

[0027] In this embodiment, a long, narrow sliding groove 41 is formed on the surface of the support plate 4 along its length. The width of the sliding groove 41 is slightly larger than the diameter of the connecting rod 52, but smaller than the diameter of the limiting member 53. The rod body of the connecting rod 52 passes through the sliding groove 41, allowing the support plate 4 to slide relative to the guide rod 5 along the extension direction of the sliding groove 41. The bottom surface of the limiting member 53 is in direct contact with the surface of the support plate 4, preventing the support plate 4 from accidentally detaching from the connecting rod 52, and restricting the support plate 4 to slide only along the sliding groove 41 and rotate around the rotating rod 31.

[0028] In this embodiment, multiple fixing positions 43 are longitudinally arranged on one side of the sliding groove 41 on the surface of the support plate 4. Each fixing position 43 communicates with the sliding groove 41. By inserting the connecting rod 52 into different fixing positions 43 on the support plate 4, the door 2 can be rigidly locked at any opening angle. The design of the limiting member 53 and the fixing positions 43 ensures that the connecting rod 52 is firmly restricted in the selected position, fundamentally eliminating the hidden danger of the door 2 falling accidentally due to the weakening of the support force, and ensuring the safety of the operator and the continuity of the operation. The fixing position 43 can be a circular hole or a U-shaped groove, the size of which is sufficient to accommodate the rod body of the connecting rod 52, and a rotating position 42 communicating with the sliding groove 41 is provided at the top of the sliding groove 41. The size of the rotating position 42 is usually larger than the width of the sliding groove 41. When the door 2 is closed, the connecting rod 52 disengages from the fixed position 43. The support plate 4 slides downward through the cooperation of the sliding groove 41 and the connecting rod 52, so that the connecting rod 52 reaches the rotating position 42, which facilitates the rotation between the support plate 4 and the connecting rod 52.

[0029] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
