Description

Technical Field

[0001] The utility model relates to the technical field of distribution frames, in particular to a distribution frame. Background Art

[0002] As a key medium for power transmission and distribution, power cables play a crucial role in modern urban power grids, outgoing lines of power stations, internal power supply systems of industrial and mining enterprises, and cross-river and cross-sea power transmission projects. With the acceleration of urbanization and the growth of industrial demand, the proportion of cables in the power system is steadily increasing, and their importance is becoming increasingly prominent.

[0003] However, during the laying and use of cables, cables sometimes have to be temporarily placed on the road surface. At this time, passing vehicles may damage the cables, affecting the stability and safety of power transmission. To solve this problem, workers often use distribution frames to lift the cables high, avoiding the cables being directly exposed on the road surface, thereby reducing the potential damage to the cables by vehicles.

[0004] The distribution frame is usually composed of three sections of telescopic pipes and a support frame installed at the top. This design allows the pipes to be telescoped as needed to adapt to cables of different lengths and different usage environments.

[0005] The support frame is usually connected to the top telescopic pipe by bolts. Although this connection method is stable, when the distribution frame needs to be moved or transported, in order to protect the support frame from damage during transportation, the operator must remove it. This disassembly and assembly process not only takes time, but also needs to repeat this step every time the distribution frame is installed, which undoubtedly increases the workload and reduces the work efficiency.

The "in one embodiment" that appears in different places in this specification does not all refer to the same embodiment, nor is it a separate or selectively mutually exclusive embodiment with other embodiments.

[0032] Embodiment 1

[0033] Referring to Figures 1 to 7 , it is the first embodiment of the present utility model. This embodiment provides a distribution frame that can be quickly telescoped to support the cable.

[0034] Specifically, it includes a first telescopic component 100, which includes a fixed pipe 101, a cross 102 connected to the bottom of the fixed pipe 101, and a first threaded hole 103 opened on the outer wall of the fixed pipe 101. Among them, the fixed pipe 101 is square, and two symmetric first threaded holes 103 are opened on two symmetric outer walls of the fixed pipe 101;

[0035] It should be noted that when the cable is supported by the distribution frame, the cross 102 needs to be fixed to the heavy object through bolts, or the cross 102 is pressed by the heavy object.

[0036] A second telescopic component 200 is arranged on the first telescopic component 100, which includes a moving pipe 201, a second threaded hole 202 opened on the outer wall of the moving pipe 201, and a limiting member 203 arranged on the outer wall of the moving pipe 201; and, among them, a threaded hole is also arranged at the bottom of the moving pipe 201. When the bottom of the moving pipe 201 moves to the top of the fixed pipe 101, the threaded hole at the bottom of the moving pipe 201 will correspond to the first threaded hole 103, and at this time, the moving pipe 201 can be fixed to the top of the fixed pipe 101 through bolts.

[0037] A third telescopic component 300 is arranged on the second telescopic component 200, which includes an installation pipe 301, a first sliding groove 302 opened on the outer wall of the installation pipe 301, an opening 303 opened on one side of the installation pipe 301, and a support member 304 arranged on the outer wall of the installation pipe 301. Among them, a threaded hole is also opened at the bottom of the installation pipe 301, and when the bottom displacement of the installation pipe 301 reaches the top of the moving pipe 201, it will correspond to the second threaded hole 202, and at this time, the installation pipe 301 and the moving pipe 201 can be connected by bolts to fix the installation pipe 301 at this position.

[0038] The inner wall of the fixed pipe 101 is slidably connected to the outer wall of the movable pipe 201, and the inner wall of the movable pipe 201 is slidably connected to the outer wall of the installation pipe 301. Among them, when deploying the distribution rack, first pull the movable pipe 201 upward so that the threaded hole at the bottom of the movable pipe 201 corresponds to the first threaded hole 103, fix the movable pipe 201 with bolts, and then pull the installation pipe 301 upward so that the threaded hole at the bottom of the installation pipe 301 corresponds to the second threaded hole 202, and then fix the installation pipe 301 at the specified position with bolts.

[0039] In summary, when assembling the distribution rack, it is possible to freely decide to first pull out the installation pipe 301 or the movable pipe 201 according to the needs. After pulling out the installation pipe 301 or the movable pipe 201, just connect it to the corresponding threaded hole with bolts to fix the installation pipe 301 or the movable pipe 201 at the specified position, and then fix the cross 102 on the road surface to complete the assembly of the distribution rack.

[0040] Embodiment 2

[0041] Refer to Figures 1 to 7 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The difference is that this embodiment can quickly retract and expand the support rod, facilitating the user to quickly disassemble and assemble the distribution rack.

[0042] The limiting member 203 includes a moving plate 203a, a limiting groove 203b opened on the outer wall of the moving plate 203a, a clamping block 203c slidably connected to the outer wall of the moving plate 203a, and a rotating rod 203e rotatably connected to the outer wall of the moving plate 203a. Among them, a groove with a width close to that of the rotating rod 203e is opened on the outer wall of the clamping block 203c away from the movable pipe 201. After the rotating rod 203e contacts the clamping block 203c, the rotating rod 203e can be clamped on the clamping block 203c by rotating the rotating rod 203e.

[0043] The outer wall of the moving plate 203a is slidably connected to the outer wall of the movable pipe 201, and the outer wall of the clamping block 203c is connected to the top of the movable pipe 201. Among them, the thickness of the moving plate 203a is less than the thickness of the clamping block 203c.

[0044] A second sliding groove 203d is opened on one side of the clamping block 203c, the outer wall of the rotating rod 203e is slidably connected to the inner wall of the second sliding groove 203d, and the outer wall of the rotating rod 203e is in contact with the outer wall of the clamping block 203c. Among them, the rotating rod 203e enters the clamping block 203c through the second sliding groove 203d.

[0045] The support member 304 includes a moving frame 304a, a moving frame 304b connected to the outer wall of the moving frame 304a, a slider 304c connected to the outer wall of the moving frame 304b, a support rod 304d rotatably connected to the outer wall of the moving frame 304a, a pull rod 304e rotatably connected to the top of the support rod 304d, a linkage rod 304f connected to the bottom of the moving frame 304b, a connecting plate 304g connected to the bottom of the linkage rod 304f, and an elastic member 304h connected to the bottom of the connecting plate 304g, wherein when the moving frame 304a, the moving frame 304b, and the slider 304c move upward, one side of the support rod 304d will be driven to move upward, and at this time, the side of the support rod 304d away from the moving frame 304a will move downward, thereby driving the pull rod 304e to move downward, so that the support rod 304d and the pull rod 304e are folded downward and enter the installation tube 301;

[0046] It should be noted that when the moving frame 304a, the moving frame 304b and the slider 304c are forced to move downward, the support rod 304d and the pull rod 304e will be stretched apart, and the linkage rod 304f and the connecting plate 304g will also squeeze the elastic member 304h. When the moving frame 304a and the moving frame 304b are no longer forced, the elastic member 304h will push the moving frame 304a and the moving frame 304b upward to move upward, so that the support rod 304d and the pull rod 304e are folded downward.

[0047] It should be noted that the elastic member 304h is a threaded spring.

[0048] The outer wall of the movable frame 304b is slidably connected to the inner wall of the mounting tube 301, and the outer wall of the slider 304c is slidably connected to the inner wall of the first slide groove 302, wherein the first slide groove 302 is used to limit the direction of the slider 304c so that the slider 304c can only slide up and down.

[0049] The outer wall of the slider 304c is slidably connected to the inner wall of the limiting groove 203b, and the outer wall of the support rod 304d is in contact with the inner wall of the opening 303, wherein when the slider 304c moves upward, it will slide in the limiting groove 203b, and when the slider 304c moves to the top of the limiting groove 203b, it will prevent the slider 304c from continuing to move upward.

[0050] The top of the support rod 304d is rotatably connected to the inner wall of the mounting tube 301, and the outer wall of the support rod 304d contacts the inner wall of the opening 303, wherein when the support rod 304d rotates, the support rod 304d will enter the mounting tube 301 through the opening 303.

[0051] The outer wall of the connecting plate 304g is slidably connected to the inner wall of the mounting tube 301 , and the bottom of the elastic member 304h is connected to the bottom of the mounting tube 301 , wherein the connecting plate 304g and the elastic member 304h are both located below the inner wall of the mounting tube 301 .

[0052] In summary, when expanding the distribution cabinet, first move the moving plate 203a upward so that the rotating rod 203e enters the second chute 203d, rotate the rotating rod 203e to engage it with the engaging block 203c, preventing the moving plate 203a from falling downward. Then, pull the installation pipe 301 so that the slider 304c moves to the top of the limiting groove 203b. The limiting groove 203b blocks the slider 304c from continuing to move upward. At this time, continuing to pull the installation pipe 301 will cause the slider 304c to move downward in the first chute 302, resulting in the downward movement of one side of the support rod 304d. In this way, the support rod 304d gradually lies horizontally, driving the pull rod 304e to tilt. When the installation pipe 301 moves to the designated position, the support rod 304d will be perpendicular to the installation pipe 301. At this time, the slider 304c will be at the bottom of the first chute 302 and the top of the limiting groove 203b and cannot move further. At this time, the cable can be lifted by the support rod 304d;

[0053] When retracting the distribution cabinet, when pushing the installation pipe 301 downward, the slider 304c will move downward in the limiting groove 203b together with the installation pipe 301, enabling the elastic member 304h to push the slider 304c to move upward in the first chute 302. In this way, when the moving frame 304a, the moving frame 304b, and the slider 304c move upward, it will drive one side of the support rod 304d to move upward. At this time, the side of the support rod 304d away from the moving frame 304a will move downward, driving the pull rod 304e to move downward, causing the support rod 304d and the pull rod 304e to fold downward into the installation pipe 301. In this way, when retracting the distribution cabinet, there is no need to disassemble the support rod 304d, thereby improving the installation efficiency of the overall distribution cabinet and protecting the support rod 304d from damage.

[0054] Embodiment 3

[0055] Referring to Figures 1 to 7 , this is the third embodiment of the present invention. Based on the previous embodiment, the difference is that corresponding components can be replaced according to requirements to make the use effect of the distribution cabinet better.

[0056] Specifically, it includes a first telescopic component 100, which includes a fixed pipe 101, a cross 102 connected to the bottom of the fixed pipe 101, and a first threaded hole 103 opened on the outer wall of the fixed pipe 101. Among them, the fixed pipe 101, the moving pipe 201, and the installation pipe 301 can be replaced with cylindrical pipes to increase the overall stability and improve the smoothness of the movement of the moving pipe 201 and the installation pipe 301;

[0057] At the same time, the cross 102 can also be replaced with different support structures, such as fixing the fixed pipe 101 to the ground through cables;

[0058] Meanwhile, a conical pipe fitting can also be installed at the bottom of the fixed pipe 101, enabling the fixed pipe 101 to be quickly fixed on the muddy ground.

[0059] In summary, the cross 102 can be replaced with other support structures according to specific requirements, enabling the distribution rack to adapt to different environments.
