Technical Field

[0001] The present invention relates to the technical field of communication cable accessories, and in particular to a cable laying and wiring device which is convenient for laying and removing. Background Art

[0002] The communication cable is composed of a cable core formed by twisting multiple mutually insulated wires or conductors and an outer sheath that protects the cable core from moisture and mechanical damage. In places where the operating environment is relatively harsh, a protective layer can also be installed on the outside of the communication cable sheath. When laying communication cables, most of them need to be carried out in cable trenches, cable tunnels and underground manholes. In the prior art, when laying communication cables, it is first necessary to install the galvanized steel plate bracket on the manhole wall through expansion bolts, and then tie the communication cable to the galvanized steel plate bracket with plastic straps.

[0003] Although the above method can conveniently complete the fixation of the communication cable, each time the communication cable is fixed, it needs to be tied with a strap, which is cumbersome. At the same time, when the communication cable is removed, the strap needs to be cut off, which results in the need to use the strap again for subsequent secondary fixation, which is a waste of manpower.

[0004] Therefore, it is necessary to invent a cable laying and wiring device that is easy to lay and remove to solve the above problems. Summary of the invention

[0005] The object of the present invention is to provide a cable laying and wiring device which is easy to lay and remove, so as to solve the problem proposed in the above-mentioned background technology that each time the communication cable is fixed, it is necessary to tie it with a strap, which is a cumbersome operation. At the same time, when the communication cable is removed, the strap needs to be cut off, which results in the need to use the strap again for subsequent secondary fixation, which is a waste of manpower.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a cable laying and wiring device that is easy to lay and remove, comprising a bracket plate, and a plurality of cable fixing mechanisms are evenly arranged on the side of the bracket plate from bottom to top;

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0022] The present invention provides Figure 1-3 A cable laying and wiring device that is easy to lay and remove is shown, such as Figure 1 As shown, it includes a bracket plate 1, and a plurality of cable fixing mechanisms 2 are evenly arranged on the side of the bracket plate 1 from bottom to top, and threaded tubes 8 are fixedly nested at the top and bottom of the side of the bracket plate 1, and expansion bolts 9 are arranged inside the threaded tubes 8. The threaded tubes 8 are threadedly connected with the expansion bolts 9, so that the bracket plate 1 can be fixed to the wall of the manhole by the expansion bolts 9.

[0023] like Figure 2 As shown, the cable fixing mechanism 2 includes a fixing seat 21, which is fixedly connected to the bracket plate 1, and a placement groove 22 is opened on the top of the fixing seat 21. A limit frame 23 is fixedly nested on the top of the side of the fixing seat 21 away from the bracket plate 1, and a sliding block 24 is slidably arranged on the inner side of the limit frame 23. A sliding rod 25 is fixedly arranged at the center of a side of the sliding block 24 away from the bracket plate 1, and a C-shaped frame 27 is fixedly arranged on the side of the fixing seat 21 away from the bracket plate 1, and the end of the sliding rod 25 passes through the inner side of the C-shaped frame 27 and extends to the outer side of the C-shaped frame 27, and the sliding rod 25 is slidably connected to the C-shaped frame 27.

[0024] More specifically, a spring 26 is sleeved on the outer side of the sliding rod 25, one end of the spring 26 is fixedly connected to the sliding block 24 and the other end of the spring 26 is fixedly connected to the C-shaped frame 27, so that the C-shaped frame 27 can support the spring 26, and then after the spring 26 is compressed, it can push the sliding block 24 to reset.

[0025] It should also be noted that a screw 3 is slidably penetrated through the bottom of the fixed seat 21 on one side away from the bracket plate 1, and the end of the screw 3 away from the bracket plate 1 penetrates the inner side of the C-shaped frame 27 and extends to the outer side of the C-shaped frame 27, and an arc-shaped clamping plate 4 is fixedly provided at the end of the screw 3 close to the bracket plate 1, and the arc-shaped clamping plate 4 is located on the inner side of the placement groove 22, and a knob 5 is movably nested at the bottom of the outer side of the C-shaped frame 27 through a bearing, and the knob 5 is sleeved on the outer side of the screw 3, and the knob 5 is threadedly connected to the screw 3 so that the knob 5 can be rotated, and then the knob 5 is used to drive the screw 3 threadedly connected thereto to move in the direction close to the bracket plate 1. At this time, the screw 3 drives the arc-shaped clamping plate 4 to press the communication cable, thereby preventing the communication cable from sliding inside the placement groove 22.

[0026] like Figure 3 As shown, an inclined surface A6 is provided on one side of the top of the fixing seat 21, and an inclined surface B7 is provided on both the side of the top of the sliding block 24 close to the bracket plate 1 and the side of the bottom close to the bracket plate 1, so that the inclined surface A6 and the inclined surface B7 can guide the communication cable when the communication cable enters and exits the placement groove 22.

[0027] Working principle of the present invention:

[0028] In actual use, firstly, the bracket plate 1 is fixed to the wall of the manhole by the expansion bolts 9, and the technicians can take the communication cable, and then press the communication cable down in the direction close to the placement groove 22 from the top opening of the placement groove 22. Due to the setting of the inclined surface A6 and the inclined surface B7, the communication cable slides along the inclined surface A6 and the inclined surface B7. In this process, the communication cable squeezes the inclined surface B7. After being squeezed, the inclined surface B7 slides on the inner side of the limit frame 23 in the direction away from the bracket plate 1, and at the same time compresses the spring 26;

[0029] When the sliding block 24 slides in a direction away from the bracket plate 1, the top opening of the placement slot 22 is exposed, and the communication cable slides into the placement slot 22 from the top opening of the placement slot 22. At this time, under the elastic force of the spring 26, the spring 26 drives the sliding block 24 to reset, thereby completing the fixation of the communication cable;

[0030] When the communication cable needs to be removed, the technician can take the two sides of the communication cable, and then pull the communication cable toward the opening of the placement slot 22. Due to the setting of the inclined surface B7 at the bottom of the sliding block 24, the communication cable slides along the inclined surface B7 at the bottom of the sliding block 24, and at the same time, the sliding block 24 is squeezed, so that the sliding block 24 slides to the right, and the communication cable slides out from the top opening of the placement slot 22.

[0031] When the communication cable enters the placement groove 22, the technician can rotate the knob 5, and then use the knob 5 to drive the screw 3 threadedly connected to it to move toward the direction close to the bracket plate 1. At this time, the screw 3 drives the arc-shaped clamping plate 4 to press the communication cable, thereby preventing the communication cable from sliding inside the placement groove 22.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
