Description

Technical Field

[0001] The utility model relates to the technical field of communication cables, in particular to a communication cable clamping device. Background Art

[0002] Communication cables are cables used to transmit telephone, telegram, fax documents, television and radio programs, data and other electrical signals. They are composed of one or more pairs of mutually insulated wires twisted together. Communication cables have the advantages of large communication capacity, high transmission stability, good confidentiality, and little influence from natural conditions and external interference.

[0003] When laying communication cables in tunnels, they are generally laid in the air. Due to external forces or the weight of the communication cables themselves, the communication cables may fall or move. At this time, it is necessary to use fixing clamps and walls or the ground to clamp and fix the communication cables to prevent them from falling. When laying communication cables, workers are required to pull the communication cables to move them. Since the communication cables are large and heavy, the workers need to rest after pulling the communication cables for a period of time. When the workers rest, the communication cables will move back due to their own gravity. If the workers keep providing pulling force to the communication cables, it will not only be time-consuming and labor-intensive, but also reduce the laying efficiency of the communication cables. Therefore, a communication cable clamping device is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-6 , a communication cable clamping device, comprising a mounting plate 1, a lower circular ring 4 and an upper circular ring 7 are arranged oppositely above the mounting plate 1, the surfaces of the lower circular ring 4 and the upper circular ring 7 are fixedly connected with a fixing plate 701, the fixing plate 701 located on the lower circular ring 4 is fixedly connected to the mounting plate 1, a buffer component is arranged in the upper circular ring 7 and the lower circular ring 4 (the buffer component can prevent the lower circular ring 4 and the upper circular ring 7 from generating a large squeezing force on the communication cable), the buffer component comprises an arc groove opened on the inner surface of the upper circular ring 7 and the lower circular ring 4, a plurality of buffer springs 501 are fixedly connected in the arc groove, an arc plate 5 is arranged oppositely in the upper circular ring 7 and the lower circular ring 4 (the upper circular ring 7 and the lower circular ring 4 clamp and fix the communication cable through two arc plates 5), the arc plate 5 is fixedly connected to the buffer spring 501, a mounting hole oppositely arranged is opened at the top of the mounting plate 1, a circular tube 8 is fixedly connected to the top of the mounting plate 1, and a slide plate 9 slidably connected to the circular tube 8 is fixedly connected to the surface of the upper circular ring 7;

[0023] The top of the mounting plate 1 is fixedly connected to a relatively arranged vertical plate 2, a rotating shaft is fixedly connected between the vertical plates 2, and a rotating tube 3 is rotatably connected to the surface of the rotating shaft (since the rotating tube 3 and the communication cable are in rolling friction, the friction force between the communication cable and the rotating tube 3 is reduced, making it easier for the staff to pull the communication cable).

[0024] Furthermore, a distance adjustment component is connected between the lower ring 4 and the upper ring 7 (the distance adjustment component can adjust the distance between the rings, so as to facilitate the clamping and fixing of the communication cable), and the distance adjustment component includes fixed blocks 401 fixedly connected to the surfaces of the lower ring 4 and the upper ring 7 and arranged relatively to each other, wherein a threaded groove is provided at the top of one of the fixed blocks 401, and a screw 6 rotatably connected to the other fixed block 401 is threadedly connected in the threaded groove, and a turntable 601 is fixedly connected to the top of the screw 6.

[0025] It should be noted that: one end of the fixed plate 701 is fixedly connected to a round rod, the surface of the round rod is rotatably connected to a rotating block 10, one end of the rotating block 10 is provided with a receiving groove, a moving block 11 is slidably connected in the receiving groove, a tension spring 1001 is fixedly connected to one side of the receiving groove and one end of the moving block 11, a coil spring is wound between the round rod and the rotating block 10, one end of the moving block 11 is fixedly connected to a rubber plate 1101, the top of the rubber plate 1101 is fixedly connected to a trapezoidal block 1102, and one end of the upper ring 7 and the lower ring 4 are both fixedly connected to a pressure plate 702 (the pressure plate 702 prevents the trapezoidal block 1102 and the rubber plate 1101 from rotating, so that the rubber plate 1101 clamps and fixes the communication cable, thereby preventing the communication cable from moving back).

[0026] A further benefit of adopting the above is that the above device does not require the staff to constantly provide tension to the communication cable, and at the same time avoids the communication cable moving back when the staff loosens the communication cable, saving time and labor while improving the laying efficiency of the communication cable.

[0027] When the utility model is in use: when it is necessary to lay the communication cable, the staff first places the communication cable on the surface of the rotating tube 3, and then passes the communication cable between the upper ring 7 and the lower ring 4, so that the surface of the communication cable contacts the two rubber plates 1101, and pulls the communication cable forward. When the communication cable is pulled for a period of time and the staff needs to take a rest, the staff releases the communication cable. Since the communication cable in the tunnel is laid in the air, the communication cable will move back under the action of its own gravity. When the communication cable moves back, the friction force generated by the contact between the communication cable and the rubber plate 1101 will drive the rubber plate 1101 and the trapezoidal block 1102 to rotate, and drive the rotating block 10 and the moving block 11 to rotate, and the moving block 11 will shrink to the inside of the rotating block 10;

[0028] When the trapezoidal block 1102 rotates to contact with the pressure plate 702, the pressure plate 702 generates a resistance force on the trapezoidal block 1102, thereby preventing the trapezoidal block 1102 and the rubber plate 1101 from continuing to rotate. When the communication cable continues to move back, due to the action of the pressure plate 702, the communication cable cannot continue to drive the trapezoidal block 1102 and the rubber plate 1101 to rotate, so that the rubber plate 1101 squeezes and clamps the communication cable, thereby preventing the communication cable from moving back. The above device does not require the staff to provide tension to the communication cable all the time, and at the same time avoids the situation where the communication cable moves back when the staff loosens the communication cable, saving time and effort while improving the laying efficiency of the communication cable.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
