Description

Technical Field

[0001] The utility model relates to the technical field of cable brackets, in particular to a bracket for laying cables. Background Art

[0002] With the development of science and technology, more and more places need to lay cables to establish power grid and communication connections. Cable trays can restrain and classify cables, prevent different cables from being placed in similar positions, which would have adverse effects on the cables, extend the service life of the cables, and improve safety.

[0003] However, since traditional cable trays require screws to fix the bracket plate, when adjusting the height of the bracket plate, the screws need to be repeatedly unscrewed and taken out and retightened to adjust and fix the bracket plate. This operation mode affects the laying efficiency of the cable.

[0004] At present, the existing Chinese patent with publication number CN220382674U discloses a cable bracket for laying cables, wherein the device is provided with a slot structure with an L-shaped cross-section on one side of the bracket fixing rod, the bracket plate is provided with an L-shaped block structure, and a spring and a compression spring plate are provided above the L-shaped block structure; although the device can quickly disassemble and assemble the bracket plate by squeezing the compression spring plate to cause the spring to contract, when the device is in use, the bracket plate has a tendency to rotate under the action of the cable, causing the compression spring plate to be compressed, and there is a risk of the bracket plate falling off. Utility Model Content

[0005] In order to overcome the deficiencies in the background technology, the utility model discloses a bracket for laying cables.

[0006] In order to achieve the above-mentioned invention object, the utility model adopts the following technical solutions:

[0007] A bracket for laying cables, comprising:

[0008] A bracket fixing rod, one side of which is provided with a plurality of installation grooves at intervals along its length direction, and the inner end of the installation groove is provided with a lower extension part and an upper extension part;

[0009] The bracket plate has an inner end surface provided with a plug rod plugged into the mounting groove, a bottom surface of the plug rod is provided with a positioning block matched with the lower extension part, and a top surface of the plug rod is provided with a stop block with a clearance between the upper end and the upper extension part;

[0010] Wherein, the distance between the top surface of the plug-in rod and the top surface of the installation groove is greater than the height of the positioning block.

[0011] Preferably, the side surface of the shift block close to the bracket plate is in contact with the corresponding side surface of the upper extension portion.

[0012] Preferably, the inner end surface of the bracket plate is provided with a slope angle corresponding to a position above the plug-in rod.

[0013] Preferably, a plurality of pairs of upward extending plates are provided at intervals on the top surface of the bracket plate along its length direction to facilitate limiting the position of the cable.

[0014] Preferably, a U-shaped hole is provided in the middle of the extension plate.

[0015] Preferably, it also includes a supporting wheel, and both ends of the supporting wheel axle respectively penetrate the U-shaped holes of the same pair of two extension plates.

[0016] Preferably, an expansion neck is provided at the outer end of the supporting wheel axle.

[0017] Preferably, a wire groove is provided in the middle of the supporting wheel body.

[0018] Preferably, the side of the bracket fixing rod facing away from the mounting groove is provided with an extension portion extending outward, and the extension portion is provided with a mounting hole along its length direction.

[0019] Due to the adoption of the above-mentioned technical solution, the utility model has the following beneficial effects:

[0020] 1. After the bracket plate is installed, the top of the stop block is still located in the inner cavity of the upper extension part. When the bracket plate is subjected to gravity and cable pressure, the stop block is blocked by the side wall of the upper extension part, so the plug rod, the positioning block and the stop block assembly will not fall out of the installation groove, which solves the technical problem of the bracket plate falling off under the action of the cable in the prior art; at the same time, the operation of disassembling and assembling the bracket plate can be completed by only controlling the angle and height of the bracket plate, which is faster and more labor-saving than the method of squeezing the compression spring plate in the prior art;

[0021] 2. The setting of the supporting wheel can support the pulled cable, and the sliding friction between the cable and the bracket plate is changed into rolling friction, which makes the laying of the cable more labor-saving. At the same time, when the cable is fixed after the pulling is completed, the supporting wheel can be removed from the extension plate, which reduces the use of the supporting wheel and thus reduces the cost.

[0026] Embodiment 1, in combination with the attached Figure 1-2 , a bracket for laying cables, comprising:

[0027] The bracket fixing rod 1 has a side surface with a plurality of installation grooves 11 spaced apart along its length direction, and the inner end of the installation groove 11 is provided with a lower extension portion 111 and an upper extension portion 112;

[0028] Furthermore, the sides of the bracket fixing rod 1 facing away from the mounting groove 11 are provided with extension portions 12 extending outward, so that the cross-section of the bracket fixing rod 1 is T-shaped, and the extension portion 12 is provided with mounting holes 121 along its length direction; in this way, the bracket fixing rod 1 can be fixed and assembled to a suitable position by means of bolts cooperating with the mounting holes 121.

[0029] The bracket plate 2 has an inner end surface provided with a plug-in rod 21 plugged into the mounting groove 11, a bottom surface of the plug-in rod 21 is provided with a positioning block 22 that matches the lower extension portion 111, and a top surface of the plug-in rod 21 is provided with a stop block 23 whose upper end portion and the upper extension portion 112 have a clearance fit; wherein the distance between the top surface of the plug-in rod 21 and the inner top surface of the mounting groove 11 is greater than the height of the positioning block 22.

[0030] When installing the bracket plate 2, first tilt the bracket plate 2, and then insert the stop block 23 into the inner cavity of the upper extension portion 112. Since the stop block 23 and the upper extension portion 112 are clearance-matched, the bracket plate 2 can be rotated at this time so that the positioning block 22 moves to the top of the lower extension portion 111 through the plug-in rod 21, and then the bracket plate 2 can be moved downward so that the positioning block 22 and the lower extension portion 111 are matched together. At this time, the top of the stop block 23 is still located in the inner cavity of the upper extension portion 112, and the installation of the bracket plate 2 is completed.

[0031] After the bracket plate 2 is installed, the top of the stop block 23 is still located in the inner cavity of the upper extension part 112. When the bracket plate 2 is subjected to gravity and cable pressure, the stop block 23 is blocked by the side wall of the upper extension part 112. Therefore, the combination of the plug-in rod 21, the positioning block 22 and the stop block 23 will not fall out of the installation groove 11, thereby solving the technical problem in the prior art that the bracket plate is at risk of falling off under the action of the cable. At the same time, the operation of disassembling and assembling the bracket plate 2 can be completed by controlling the angle and height of the bracket plate 2. Compared with the method of squeezing the compression spring plate in the prior art, it is faster and more labor-saving.

[0032] Embodiment 2, combined with the attached Figure 1-2 A cable laying bracket is provided. On the basis of the first embodiment, in order to improve the stability of the bracket plate 2 after assembly, the side of the stop block 23 close to the bracket plate 2 is attached to the corresponding side of the upper extension portion 112; that is, after the bracket plate 2 is installed, the surface force of the resistance to which the stop block 23 is subjected can prevent the stop block 23 from deforming.

[0033] In this embodiment, in order to ensure that the inner end surface of the bracket plate 2 corresponding to the position below the plug rod 21 is in contact with the side of the bracket fixing rod 1 and increase the stability of the bracket plate 2, a slope angle 24 is provided at the inner end surface of the bracket plate 2 corresponding to the position above the plug rod 21.

[0034] Embodiment 3, in combination with the attached Figure 1-2 A cable laying bracket, based on the first or second embodiment, when pulling the cable during cable laying, in order to prevent the cable from being excessively offset or even falling off the bracket plate 2, a plurality of pairs of upward extension plates 25 are provided at intervals along the length direction of the bracket plate 2. It should be noted that a pair of extension plates 25 has two, specifically, a receiving gap for accommodating the cable is provided between the two paired extension plates 25. In this way, the laid cable can be confined between the two paired extension plates 25.

[0035] Embodiment 4, in combination with the attached Figure 1-2 , a bracket for laying cables, based on the third embodiment, a U-shaped hole 251 is provided in the middle of the extension plate 25.

[0036] The supporting wheel 3 is also included. The two ends of the wheel shaft of the supporting wheel 3 respectively penetrate the U-shaped holes 251 of the same pair of two extension plates 25; and the outer end of the wheel shaft of the supporting wheel 3 is provided with an expansion neck 31.

[0037] A wire groove 32 is provided in the middle of the supporting wheel body.

[0038] The pulled cable is supported by the supporting wheel 3 in this way, and the sliding friction between the cable and the bracket plate 2 is changed into rolling friction, so that laying the cable is more labor-saving.

[0039] Furthermore, in order to prevent the cable outlet from being worn, the front and rear sides of the upper surface of the bracket plate 2 corresponding to the cable pulling direction are provided with arc chamfers.

[0040] Furthermore, the bracket plate 2 is a triangular structure so as to increase the strength of the bracket plate 2 .

[0041] This arrangement enables the cable to be located on the supporting wheel 3 when the cable needs to be pulled, and when the cable is fixed after pulling, the supporting wheel 3 can be removed from the extension plate 25, thereby reducing the use of the supporting wheel 3 and thus reducing the cost. It should be noted that when an insulator is required to fix the cable, a mounting hole for installing the insulator is provided on the bracket plate 2.

[0042] The parts of the present invention that are not described in detail are prior art. It is obvious to those skilled in the art that the present invention is not limited to the details of the above-mentioned exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and it is intended that all changes that fall within the meaning and scope of equivalent elements are included in the present invention.
