Description

A wire protection device

technical field

The invention relates to a safety protection device for electric work, in particular to a line end protection device.

Background technique

During power maintenance and daily work, exposed wires are often encountered. For the safety of the operator, it is necessary to deal with the exposed wires, that is, to wrap insulating tape on the exposed wires. Remove the insulating tape. Such a process of winding and removing is not only a waste of time, but also when winding and removing, the operator can easily touch the exposed part of the wire, which is extremely unsafe.

Contents of the invention

The technical problem to be solved by the present invention is to provide a wire end protection device, which can not only quickly protect the exposed wires, but also has a high safety factor.

The technical solution adopted by the present invention to solve the above problems is:

A wire end protection device, comprising a protective tube, clamping holes are respectively provided at both ends of the diameter of the protective tube, a clamping device is arranged in the clamping hole, and the clamping device includes a first clamping The first clamping piece and the second clamping piece are movably connected with the first clamping piece, and the first clamping piece and the second clamping piece are provided with a groove at the clamping hole, and the groove is provided with The rubber layer is provided with protruding teeth, and the unconnected ends of the first clamping piece and the second clamping piece are provided with fastening devices.

Preferably, the fastening device is a rubber ring.

Preferably, the fastening device includes connecting rings respectively fixed on the first clamping piece and the second clamping piece and springs connected between the connecting rings.

Further, the spring is an extension spring.

Further, one end of the protective tube is trumpet-shaped.

In sum, the beneficial effects of the present invention are:

1. The present invention uses a protective tube to seal the exposed wires, and uses a clamping device to clamp the wires. The protective tube is clamped on the wires, which completely seals the exposed wires and has a high safety factor.

2. In the present invention, the protective tube is put on the wire, and the wire is clamped by the clamping device to complete the operation, and the operation is simple and fast.

Detailed ways

The present invention will be further described in detail below with reference to the embodiments and accompanying drawings, but the embodiments of the present invention are not limited thereto.

Example 1:

A thread protection device as shown in Fig. 1, Fig. 2 and Fig. 3 includes a protective tube 1, the two ends of the diameter of the protective tube 1 are respectively provided with clamping holes, and the clamping holes are provided with clamping holes. The clamping device, the clamping device includes a first clamping piece 3 and a second clamping piece 4 that is movably connected with the first clamping piece 3, and the first clamping piece 3 and the second clamping piece 4 A groove 9 is arranged at the clamping hole, and a rubber layer 8 is arranged in the groove 9, and convex teeth are arranged on the rubber layer 8, and the first clamping piece 3 and the second clamping piece A fastening device is provided on the unconnected end of the holding piece 4 .

In this embodiment, the exposed wires are packaged with a protective tube, that is, the exposed wires are wrapped to prevent people from touching the wires. The clamping device clamps the wire, and the diameter of the protective tube is larger than that of the wire. The clamping device clamps the wire to prevent the protective tube from slipping off the wire. The clamping device is located in the clamping hole and clamps the wire conduit from both ends. One end of the first clamping piece 3 and the second clamping piece 4 are movably connected and the other end is connected by a fastening device. Since the cross section of the wire is circular, when the wire is clamped, the first clamping piece 3 and the second clamping The groove 9 on the holding piece 4 fits the wire to enhance the clamping force on the wire. The friction coefficient of the rubber layer 8 is large, and the convex teeth on the rubber layer 8 further increase the friction with the wire to further enhance the clamping force . When in use, the protective tube 1 is directly put on the wire, and the clamping device is clamped in the clamping hole, and the operation is quick and simple.

Example 2:

As shown in FIG. 1 and FIG. 3 , a thread protection device, this embodiment refines the warp device on the basis of the above-mentioned embodiment 1, that is, the fastening device is a rubber ring 5 . The rubber ring 5 is used to fix the first clamping piece 3 and the second clamping piece 4, which is not only easy to operate, but also low in price.

Example 3:

As shown in Fig. 2 and Fig. 3, a kind of thread protection device, on the basis of the above-mentioned embodiment 1, this embodiment refines the warp device, that is, the fastening device includes 3 and the connecting ring 6 on the second clamping piece 4 and the spring 7 connected between the connecting ring 6 .

The spring 7 is a tension spring.

The other ends of the first clamping piece 3 and the second clamping piece 4 are fixed by tension springs, which have a strong fixing effect and are convenient for installation and removal.

Example 4:

As shown in Fig. 1, Fig. 2 and Fig. 3, one end of the protective tube 1 is trumpet-shaped for the convenience of operation. One end of the protective tube 1 is set in a trumpet shape, which is convenient for passing the wire into the protective tube 1 .

As described above, the present invention can be preferably carried out.
