[0027] The utility model will be described in detail below with reference to the drawings and in combination with the embodiments.

[0028] A kind of cable threading device for switch board, its structure can be by Figures 1-6 Schematically described.In the embodiment, the cable threading device for switch board includes: lead pipe 1, wiring pipe 2 and wire arrangement component, wherein lead pipe 1 and wiring pipe 2 are used to realize the communication between bridge and switch board, and protect cable, and wire arrangement component is used to fix cable, to facilitate staff to comb and guide cable, facilitate subsequent wiring work to carry out.

[0029] When assembling, the top end of lead pipe 1 should be communicated with bridge, the bottom end of wiring pipe 2 should be communicated with switch board, and the top end of wiring pipe 2 is slidably arranged inside the bottom end of lead pipe 1.Before use, staff can drive the top end of wiring pipe 2 to slide inside lead pipe 1 according to the distance between bridge and switch board, to adapt to the assembly requirement under a plurality of different space conditions.

[0030] Optionally, in order to realize the communication between the lead tube 1 and the bridge, the top end of the lead tube 1 is provided with a first connecting disc 11 and a first connecting pipe 12. During assembly, the first connecting disc 11 is detachably mounted on the bridge through bolts, and the first connecting pipe 12 is inserted into the cutting opening pre-provided on the bridge, so that the cable in the bridge enters the lead tube 1. Correspondingly, the bottom end of the wiring tube 2 is provided with a second connecting disc 23 and a second connecting pipe 24. During assembly, the second connecting disc 23 is detachably connected with the power distribution cabinet through bolts, and the second connecting pipe 24 is inserted into the cutting opening pre-provided on the power distribution cabinet, so that the cable in the device enters the power distribution cabinet.

[0031] In actual work process, the bridge and the power distribution cabinet are usually made of metal materials, so that after the cutting opening is provided on the bridge and the power distribution cabinet, sharp edges are easily formed inside the cutting opening, thereby causing the risk of scratching the cable. In order to solve this problem, the first connecting pipe 12 and the second connecting pipe 24 in the embodiment are both made of rubber materials, and the lengths of the first connecting pipe 12 and the second connecting pipe 24 are both greater than the wall thicknesses of the bridge and the power distribution cabinet, so as to protect the cable by means of the first connecting pipe 12 and the second connecting pipe 24. In addition, in order to prevent the cable from being damaged in the device, a protection slope 25 is further provided at the top end of the wiring tube 2, so as to form a smooth transition between the lead tube 1 and the wiring tube 2 by means of the protection slope 25, thereby avoiding the cable from being scratched by the sharp edges at the top end of the wiring tube 2.

[0032] Optionally, in order to facilitate the locking of the position of the wiring tube 2, an adjusting bolt 7 is further provided on the wiring tube 2 in the embodiment, the adjusting bolt 7 is provided with a locking nut 71, and a guide cutout 13 for accommodating the adjusting bolt 7 is provided on the side wall of the lead tube 1. During assembly, the adjusting bolt 7 is inserted into the guide cutout 13, and the locking nut 71 is located outside the lead tube 1. When the top end of the wiring tube 2 is slid to a suitable position, the worker can tighten the locking nut 71, so as to clamp and fix the side wall of the lead tube 1 by means of the locking nut 71 and the screw head of the adjusting bolt 7, thereby preventing the top end of the wiring tube 2 from abnormally sliding.

[0033] Figure 6 The schematic diagram of the wire arrangement assembly is shown in the figure. The wire arrangement assembly in the embodiment includes a bearing strip 3 and a plurality of wire arrangement clips 5. The bearing strip 3 is used to provide a mounting basis for the wire arrangement clips 5, so as to fix the wire arrangement clips 5 inside the wiring tube 2. The wire arrangement clips 5 are used to fix the cable, thereby facilitating the worker to comb and guide the cable.

[0034] Specifically, in order to realize the installation of the wire arrangement assembly, the inside of the wiring pipe 2 should be provided with a guide inner wall and a limiting inner wall. The limiting inner wall is perpendicular to the guide inner wall, a plurality of guide grooves 21 are arranged on the guide inner wall, and a limiting groove 22 is arranged on the limiting inner wall. In order to realize the fixation and arrangement of the cable, a guide notch 31 is arranged on the bearing strip 3 in a length direction perpendicular to the length direction of the guide groove 21, a limiting block 4 is arranged on the side of the bearing strip 3 close to the limiting inner wall, and the limiting block 4 is connected to the bearing strip 3 through an elastic assembly. A containing groove 51 for containing the cable is arranged on the side wall of the wire arrangement clamp 5 away from the bearing strip 3, a guide rod 52 is arranged on the side wall of the wire arrangement clamp 5 close to the bearing strip 3, and the guide rod 52 is slidably arranged in the guide notch 31. A detachable limiting round cap 53 is further arranged at the end of the guide rod 52 away from the wire arrangement clamp 5, and the outer diameter of the limiting round cap 53 is greater than the notch width of the guide notch 31.

[0035] In use, the staff can first insert the cable into the containing groove 51, then pass the guide rod 52 through the guide notch 31, and install the limiting round cap 53 on the guide rod 52. Since the outer diameter of the limiting round cap 53 is greater than the notch width of the guide notch 31, after the installation of the limiting round cap 53 is completed, the guide rod 52 cannot be separated from the guide notch 31, so as to install the wire arrangement clamp 5 on the bearing strip 3, and complete the fixation between the cable and the wire arrangement assembly. The staff can also adjust the position of the guide rod 52 in the guide notch 31 according to the subsequent wiring requirements of the cable, so as to guide the subsequent direction of the cable and reduce the difficulty of subsequent wiring. Next, the staff can install the wire arrangement assembly into the wiring pipe 2, at this time the limiting block 4 should be inserted into the limiting groove 22. Since the limiting block 4 is connected to the bearing strip 3 through the elastic assembly, the elastic force generated by the elastic assembly can make the limiting block 4 abut against the inner wall of the limiting groove 22, so as to prevent the wire arrangement assembly from being separated from the wiring pipe 2. At the same time, the limiting round cap 53 can also be slidably inserted into the guide groove 21, so as to limit the position of the guide rod 52 in the guide notch 31, and avoid abnormal movement of the wire arrangement clamp 5 after installation.

[0036] As shown in Figs. 1 to 3, the wire arrangement assembly comprises a wiring pipe 2, a bearing strip 3, a wire arrangement clamp 5 and a limiting block 4. Figure 4 and Figure 5 As shown in Figs. 4 and 5, when the wiring pipe 2 is a square pipe, the inside of the wiring pipe 2 can be provided with two guide inner walls and two limiting inner walls, at this time the staff can install the bearing strip 3 on any one of the guide inner walls according to the subsequent wiring requirements of the cable, so as to obtain better guiding effect of the cable. Correspondingly, the staff can also adjust the position of the wire arrangement assembly on the guide inner wall along the length direction of the guide groove 21, so that a plurality of wire arrangement assemblies can be installed on the same guide inner wall at the same time, so that the device can obtain a larger number of cable fixation.

[0037] In the embodiment, the elastic assembly can include a connecting rod 61 and a spring 62, and a mounting hole 32 can be provided on the carrying strip 3. Figure 6 As shown, one end of the connecting rod 61 should be connected with the limiting block 4, and the other end is slidingly arranged inside the mounting hole 32, the spring 62 is sleeved on the connecting rod 61, and one end of the spring 62 is connected with the limiting block 4, and the other end is connected with the carrying strip 3. When the cable arrangement is installed in the wiring tube 2, the staff can press the limiting block 4 towards the carrying strip 3, so that the limiting block 4 enters the limiting groove 22, at this time the connecting rod 61 will slide into the mounting hole 32, so that the spring 62 is compressed. When the limiting block 4 enters the limiting groove 22 smoothly, the elastic force generated by the compression of the spring 62 will drive the limiting block 4 to abut against the inner wall of the limiting groove 22, so as to fix the position of the cable arrangement in the wiring tube 2.

[0038] Optionally, in order to improve the abutting fixing effect of the limiting block 4 and facilitate the entry of the limiting block 4 into the limiting groove 22, the side of the limiting block 4 away from the carrying strip 3 can be provided with a positioning surface 41, a non-slip pad made of rubber material can be provided on the positioning surface 41, and a guide inclined surface 42 can be provided at the upper and lower ends of the positioning surface 41.

[0039] The effects of the above scheme are described as follows:

[0040] The cable arrangement for power distribution cabinet provided in the embodiment can realize the communication between the bridge and the power distribution cabinet through the cooperation of the lead tube and the wiring tube, and adapt to the installation requirements of various different spaces. Secondly, the device can fix, comb and guide the cable through the cable arrangement, which facilitates the subsequent wiring work. In addition, the device can prevent the abnormal movement of the cable through the cooperation of the limiting block, the limiting groove, the guide groove and the limiting round cap.

[0041] The above only describes the preferred embodiments of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the utility model should be included in the protection scope of the utility model.
