Description

Technical Field

[0001] The utility model relates to the technical field of wire and cable, and particularly relates to a wire and cable protection drag chain which is convenient for assembly. Background Art

[0002] When wire and cable are used in equipment and need to move back and forth, in order to prevent the cable from being entangled, worn, pulled off, hung and scattered, it is necessary to put the wire and cable into a drag chain to protect the wire and cable, and the cable can also move back and forth with the drag chain. Such a cable can move back and forth with the drag chain and is not easily worn, so it is widely used. For this reason, we provide a wire and cable protection drag chain which is convenient for assembly.

[0003] Most of the existing wire and cable protection drag chains are fixedly connected. During maintenance, the whole drag chain needs to be removed, which is time-consuming and laborious, resulting in inconvenience in use and thus reducing work efficiency. Content of the Utility Model

The protection drag chain body includes drag chain side plates, and a drag chain cover plate is detachably installed on the top of the drag chain side plates. A wire and cable is arranged inside the drag chain side plates at the bottom end of the drag chain cover plate.

[0007] Connecting units are arranged on both sides of the drag chain side plates, and disassembly and assembly units are arranged at both ends of the drag chain cover plate.

[0008] The further improvement of the technical solution of the utility model lies in that: the connecting unit includes engaging grooves opened at both outer ends of the drag chain side plates. A limiting round block is fixedly installed at the middle position inside the engaging grooves. A connecting rotating plate is detachably and engagingly installed inside the engaging grooves. Positioning holes are opened on both sides of the connecting rotating plate, and the connecting rotating plate is convenient for connecting two adjacent side plates.

[0009] The further improvement of the technical solution of the utility model lies in that: piston rods are fixedly installed on the inner groove walls of the engaging grooves at both outer ends of the drag chain side plates. The other ends of the piston rods are movably sleeved with positioning sleeves, and the other ends of the positioning sleeves are movably inserted into the positioning holes.

[0010] A further improvement of the technical solution of the present utility model lies in that: a return spring is movably sleeved on the outer surface of the piston rod. The left end of the return spring is fixedly connected to the inner wall of the groove, and the right end of the return spring is fixedly connected to the outer surface of the left end of the positioning sleeve. A toggle piece is fixedly sleeved on the outer surface of the positioning sleeve at the left end. When the toggle piece moves backward, it can drive the positioning sleeve to disengage from the fixation of the connecting rotating plate.

[0011] A further improvement of the technical solution of the present utility model lies in that: the disassembly and assembly unit includes connecting grooves opened at the upper and lower ends of the side plate of the drag chain. Fixing holes are opened inside the connecting grooves. Disassembly cavities are opened on both sides of the top of the drag chain cover plate, and extrusion grooves are opened on the inner sides of the disassembly cavities.

[0025] Furthermore, by assembling two sets of drag chain side plates 2 as needed, the two ends of the two sets of drag chain side plates 2 cooperate with the connecting rotating plates 23 to be correspondingly engaged in the inside of the engaging grooves 21 at both ends of the drag chain side plates 2, and the positioning sleeve 26 slides outward on the outer surface of the piston rod 25 under the elastic pushing force of the return spring 27, and then is inserted into the inside of the positioning hole 24 to fix the connection of the connecting rotating plates 23, thereby multiple drag chain side plates 2 can be assembled at will according to the length requirements of the wires and cables 4. Example

[0026] like Figures 1-5 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the disassembly and assembly unit includes a connecting groove 29 opened at the upper and lower ends of the drag chain side plate 2, a fixing hole 210 is opened inside the connecting groove 29, a disassembly cavity 31 is opened on both sides of the top of the drag chain cover plate 3, an extrusion groove 32 is opened on the inner side of the disassembly cavity 31, a fixed connecting block 33 is movably inserted on the outer side of the disassembly cavity 31, connecting rods 34 are fixedly installed on both sides of the inner end of the fixed connecting block 33, a rotating shaft 35 is fixedly installed on the other end of the connecting rod 34, an extrusion plate 36 is rotatably connected at the inner axis of the rotating shaft 35, and elastic wires 37 are arranged on both sides of the extrusion plate 36, one end of the elastic wire 37 is fixedly installed on both sides of the inner end of the fixed connecting block 33, and the other end of the elastic wire 37 is fixedly installed on both sides of the inner end of the disassembly cavity 31.
