The cable protection tube has the characteristics of high strength, good flexibility, high temperature resistance, high pressure resistance, corrosion resistance, flame retardance, good insulating property, difficult aging, light weight and the like, and can also prevent the influence of expansion with heat and contraction with cold. The cable protection pipe replaces the defects of poor rigidity, poor heat resistance, poor flame retardance and the like of the traditional double-wall corrugated pipe ring, and is a necessary trend for future development.

The cable protection pipe is mainly installed in a section where the communication cable protection pipe and a power line are crossed, so that the power line is prevented from being broken to cause a short circuit accident, the communication cable protection pipe and a steel wire rope are electrified to protect a pipe, a switch and a machine core plate, the whole machine is not burnt out, and a certain isolation effect is achieved on the magnetic field interference of the power line. With the development of electric power communication industry, the application of cable protection pipes is very popular.

However, the cable is difficult to penetrate into the protective tube, especially when the protective tube is long, because the cable is prevented from moving in the protective tube due to friction with the inner wall of the protective tube. Meanwhile, the cable generates heat or generates static electricity when it rubs against the inner wall of the protective tube over a large area.

Therefore, it is necessary to develop a new type of cable protection pipe, which can satisfy the requirement for overhead line and underground wiring, and in addition, the quick pipe joint for threading is generally installed at the joint of the cable protection pipe, and the linear pipe joint can be used to increase the length of threading the cable pipe, so as to connect two cable protection pipes together.

In view of the above-mentioned drawbacks, the present inventors have made active research and innovation to create a quick pipe joint for a cable protection tube having a higher industrial utility value.

The utility model discloses a quick coupling that cable protection pipe was used, the centre frame of coupling body is equipped with the round go-between, be equipped with a plurality of supports between the inner wall of go-between and coupling body the slide bar that the go-between was used, the one end of slide bar is connected to be fixed on the go-between, the other end of slide bar is fixed on the inner wall of coupling body, the go-between is through a plurality of the slide bar is divided into a plurality of sections rings body, all has struggled at least one on every section ring body can along the gliding first ball of ring body, each all struggle at least one on the slide bar can along gliding second ball about the slide bar.

Furthermore, each slide bar is provided with two second balls capable of sliding up and down along the slide bar in a stringing manner.

Furthermore, each section of ring body is provided with a first ball capable of sliding along the ring body in a serial mode.

Further, the diameter of the first ball is larger than that of the second ball.

Furthermore, the sliding rod, the connecting ring and the pipe joint body are integrally formed.

Furthermore, a third ball is fixedly strung on one end of the sliding rod, which is close to the inner wall of the pipe joint body.

Furthermore, the third ball is connected with the inner wall of the pipe joint body in an interference mode.

Borrow by above-mentioned scheme, the utility model discloses at least, have following advantage:

compared with the prior art, the cable protection tube has the advantage that the action of threading the cable protection tube into the tube body can be well facilitated.

The above description is only an overview of the technical solution of the present invention, and in order to make the technical means of the present invention clearer and can be implemented according to the content of the description, the following detailed description is made with reference to the preferred embodiments of the present invention and accompanying drawings.

Detailed Description

The following detailed description of the embodiments of the present invention is provided with reference to the accompanying drawings and examples. The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention.

Fig. 1 shows a quick coupling for cable protection tube, the center frame of coupling 7 body is equipped with a round of go-between 1, be equipped with a plurality of slide bars 2 that support go-between 1 usefulness between the inner wall of go-between 1 and coupling 7 body, the one end of slide bar 2 is connected and is fixed on go-between 1, the other end of slide bar 2 is fixed on the inner wall of coupling 7 body, go-between 1 divides into a plurality of sections rings through a plurality of slide bars 2, all cluster at least one can be along the gliding first ball 3 of ring body on every section ring body, all cluster at least one can be along slide bar 2 gliding second ball 4 from top to bottom on every slide bar 2.

The utility model provides a quick coupling's that cable protection was used principle as follows:

a circle of connecting rings 1 are erected at the center of the body of the pipe joint 7, the connecting rings 1 can accommodate the passing of cables, a plurality of slide bars 2 for supporting the connecting ring 1 are arranged between the connecting ring 1 and the inner wall of the pipe joint 7 body, can well support and fix the connection ring 1, one end of the slide bar 2 is fixedly connected with the connection ring 1, the other end of the slide bar 2 is fixed on the inner wall of the pipe joint 7 body, in this way, the sliding rods 2 can divide the area between the connecting ring 1 and the inner wall of the pipe joint 7 into the branch pipes 5, in addition, the connecting ring 1 is divided into a plurality of sections of ring bodies through a plurality of sliding rods 2, at least one first ball 3 capable of sliding along the ring bodies is strung on each section of ring body, at least one second ball 4 capable of sliding up and down along the sliding rods 2 is strung on each sliding rod 2, and the first ball 3 and the second ball 4 are used for enabling the cable to smoothly pass through.
