Technical Field

[0001] The utility model relates to the technical field of cable installation, in particular to a fire-fighting twisted-pair cable. Background Art

[0002] Fire twisted pair cable is a cable used to connect fire equipment and fire control center. It adopts twisted pair structure and can transmit various control signals and data signals. This cable is widely used in indoor wiring of buildings, elevator control signal transmission, security system video transmission, data transmission and power distribution.

[0003] As disclosed in publication number CN217640724U, a fire-fighting twisted-pair cable comprises a wire core 1, a wire core 2 and a high-temperature resistant filling layer, the wire core 2 is arranged on one side of the wire core 1, and an insulating layer is arranged on the outer side walls of the wire core 1 and the wire core 2. The beneficial effect is that the utility model can smoothly drag the twisted-pair cable on the ground when used in firefighting tasks through the design of the oil absorption fiber layer and the lubricating oil, so that firefighters or other staff can quickly pull and drag the twisted-pair cable to ensure the convenience of using the twisted-pair cable, and through the design of the wear-resistant rubber layer, the high-temperature resistant filling layer and the thermal insulation layer, the twisted-pair cable can be made of wear-resistant and high-temperature resistant materials, so that the twisted-pair cable can withstand higher temperatures and avoid damage during firefighting tasks, thereby ensuring the normal use of the cable.

[0004] This patent can enable the twisted pair cable to be smoothly dragged on the ground when used in firefighting tasks through the design of the oil absorption fiber layer and the lubricating oil. However, when installing existing twisted pair cables, they are usually fixed directly on the wall through buckles. When the operator needs to check the connection status and integrity of the twisted pair cables, the buckles can only be destroyed and disassembled, and then the twisted pair cables can be reinstalled through the buckles, which is time-consuming and labor-intensive. Therefore, we have proposed a new type of fire-fighting twisted pair cable. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that the existing twisted-pair cables in the prior art are usually installed directly on the wall by means of buckles. When the operator needs to check the connection status and integrity of the twisted-pair cables, the buckles can only be destroyed and disassembled, and then the twisted-pair cables can be reinstalled by means of the buckles, which is time-consuming and labor-intensive.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a fire-fighting twisted-pair cable, comprising a twisted-pair cable body, a convenient disassembly and assembly component is arranged on one side surface of the twisted-pair cable body, the convenient disassembly and assembly component comprises a mounting plate, four corners of the mounting plate are connected with side ears, a screw groove is opened inside the mounting plate, a bidirectional screw is inserted inside the screw groove, a handle is connected to the top of the bidirectional screw, a bearing is connected to the bottom of the bidirectional screw, two groups of clamps are symmetrically arranged on the surface of the bidirectional screw, threaded holes are opened on one side of the two groups of clamps, and grooves are opened on the inner side of the two groups of clamps.

[0007] Furthermore, the bidirectional screw and the handle are fixedly connected, and the bidirectional screw and the bearing are rotatably connected.

[0008] Furthermore, the clamping plate is threadedly connected to the bidirectional screw through the threaded hole, and the position and size of the groove match the position and size of the twisted pair cable body.

[0009] Furthermore, the inner surface wall of the groove is in contact with the outer surface of the twisted pair cable body.

[0010] Furthermore, a peeling component is connected to the other side of the twisted pair cable body, and the peeling component includes a fixing block, and two sets of springs are fitted and connected to the inner walls on both sides of the fixing block.

[0011] Furthermore, the upper and lower ends of the two groups of springs are connected to push plates, and the top and bottom of the push plates are respectively connected to push blocks and cutters.

[0012] Furthermore, an elastic structure is formed between the push plate and the spring, and the outer surface of the push plate is in contact with the inner surface wall of the fixing block.

[0013] Compared with the prior art, the advantages and positive effects of the utility model are:

[0014] 1. In the utility model, when the twisted-pair cable body needs to be installed for the first time, the side ears and the wall can be directly fixed by bolts to achieve the installation of the twisted-pair cable body. When the twisted-pair cable body needs to be disassembled, the handle can be turned to drive the bidirectional screw to rotate so that the two sets of clamps are away from the surface of the twisted-pair cable body. Then the twisted-pair cable body can be directly removed for disassembly, avoiding the problem that the existing twisted-pair cable body is inconvenient to disassemble after installation.

[0015] 2. In the utility model, when it is necessary to peel or cut the main body of the twisted pair cable, the push block is directly grasped to push the cutter to peel or cut the main body of the twisted pair cable, thereby avoiding the need to use professional tools such as pliers when peeling the main body of the existing twisted pair cable, thereby improving the convenience of operating the main body of the twisted pair cable.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0023] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0024] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a fire-fighting twisted-pair cable, including a twisted-pair cable body 1, a convenient disassembly assembly 2 is arranged on one side surface of the twisted-pair cable body 1, the convenient disassembly assembly 2 includes a mounting plate 201, four corners of the mounting plate 201 are connected with side ears 202, a screw groove 203 is opened inside the mounting plate 201, a bidirectional screw 204 is inserted inside the screw groove 203, a handle 205 is connected to the top of the bidirectional screw 204, a bearing 206 is connected to the bottom of the bidirectional screw 204, and the surface of the bidirectional screw 204 is symmetrical Two groups of clamping plates 207 are provided, and threaded holes 208 are opened on one side of the two groups of clamping plates 207, and grooves 209 are opened on the inner sides of the two groups of clamping plates 207. The bidirectional screw 204 and the handle 205 are fixedly connected, and the bidirectional screw 204 and the bearing 206 are rotatably connected. The clamping plates 207 are threadedly connected to the bidirectional screw 204 through the threaded holes 208. The position and size of the groove 209 match the position and size of the twisted pair cable body 1, and the inner surface wall of the groove 209 fits with the outer surface of the twisted pair cable body 1.

[0025] The effect achieved by the entire embodiment 1 is that when the twisted-pair cable body 1 needs to be installed for the first time, the mounting plate 201 can be directly attached to the wall, and then the side ears 202 are penetrated by bolts to fix and install with the wall, so that the installation of the twisted-pair cable body 1 is realized through the mounting plate 201. When the twisted-pair cable body 1 needs to be disassembled and inspected, the handle 205 can be rotated in the reverse direction, so that the handle 205 can drive the bidirectional screw 204 to rotate in the reverse direction. While the handle 205 is rotating, it will also rotate in the reverse direction with the two sets of clamping plates 207 through the threaded holes 208, thereby causing the two sets of clamping plates 207 to rotate in the reverse direction. Keep away from the surface of the twisted pair cable body 1, and then directly remove the twisted pair cable body 1 for disassembly. After the inspection of the twisted pair cable body 1 is completed, when the twisted pair cable body 1 needs to be installed, directly place the twisted pair cable body 1 between the two sets of clamps 207. At this time, the handle 205 can be rotated forward to drive the bidirectional screw 204 to rotate forward, so that the two sets of clamps 207 can simultaneously push the twisted pair cable body 1, and clamp and fix the twisted pair cable body 1 through the groove 209, so as to complete the quick disassembly and assembly of the twisted pair cable body 1, avoiding the problem that the existing twisted pair cable body 1 is inconvenient to disassemble after installation.

[0026] Embodiment 2, as Figure 1 , Figure 2 and Figure 5As shown, a peeling component 3 is connected to the other side of the twisted pair cable body 1, and the peeling component 3 includes a fixed block 301, and two sets of springs 302 are fitted and connected to the inner walls on both sides of the fixed block 301, and the upper and lower ends of the two sets of springs 302 are connected to push plates 303, and the top and bottom of the push plates 303 are respectively connected to push blocks 305 and cutters 304, and an elastic structure is formed between the push plates 303 and the springs 302, and the outer surface of the push plates 303 is fitted with the inner wall of the fixed block 301.

[0027] The effect achieved by the entire embodiment 2 is that when it is necessary to peel or cut the twisted pair cable body 1, the two groups of push blocks 305 are grasped and squeezed inward at the same time, so that the two groups of push blocks 305 can push the push plate 303 to drive the cutter 304 to peel or cut the twisted pair cable body 1, and squeeze the spring 302. After the peeling of the twisted pair cable body 1 is completed, the push block 305 is released, so that the spring 302 pushes the push plate 303 to push the cutter 304 to the inside of the fixed block 301, so as to prevent the cutter 304 from being exposed for a long time to cause harm to the operator, avoid the need to use professional tools such as pliers when the existing twisted pair cable body 1 is peeled, and improve the convenience of operating the twisted pair cable body 1.

[0028] Working principle: When the twisted-pair cable body 1 needs to be installed for the first time, the side ear 202 can be directly fixed to the wall by bolts to achieve the installation of the twisted-pair cable body 1. When the twisted-pair cable body 1 needs to be disassembled, the handle 205 can be turned to drive the bidirectional screw 204 to rotate, so that the two sets of clamps 207 are away from the surface of the twisted-pair cable body 1. Then the twisted-pair cable body 1 can be directly removed for disassembly, avoiding the problem that the existing twisted-pair cable body 1 is inconvenient to disassemble after installation. When the twisted-pair cable body 1 needs to be peeled or cut, the push block 305 can be directly grasped to push the cutter 304 to peel or cut the twisted-pair cable body 1. This avoids the need to use professional tools such as pliers when peeling the existing twisted-pair cable body 1, thereby improving the convenience of operating the twisted-pair cable body 1.
