Description

UPVC cable protection sleeve device

Technical Field

The utility model relates to a cable protection sleeve device.

Background

The cable protection pipe is a metal protection pipe which is laid on the outer layer of the cable and has certain mechanical strength in order to prevent the cable from being damaged. The cable protection pipe is mainly installed in a section where the communication cable and the power line are crossed, so that the short circuit accident caused by the disconnection of the power line is prevented, the communication cable and the steel wire rope are electrified, the cable, the switch and the machine core board are protected, the whole machine is not burnt out, and a certain isolation effect is achieved on the magnetic field interference of the power line. In the prior art, the cable protection sleeve is a straight long pipe, and is suitable for protecting the appearance of a cable which is long in straight length and does not turn, but for a cable which is short in straight length and needs to turn, the long pipe needs to be broken according to the required length, the common CPVC cable protection sleeve is thick in material, needs a special tool to be broken, and is low in construction efficiency. In addition, the cable protective sleeve is sleeved on a cable with a longer straight length and is influenced by friction force, and the friction force is increased along with the lengthening of the sleeved cable, so that the labor intensity of constructors is increased.

Disclosure of Invention

Utility model purpose: in order to overcome the defects, the utility model provides a cable protection sleeve device which is convenient to install and disassemble.

The technical scheme is as follows: the utility model adopts a UPVC cable protection sleeve device, which comprises a sleeve straight pipe and a corrugated pipe, wherein the sleeve straight pipe is fixedly connected with the corrugated pipe to form a protection sleeve unit; the inner wall of the straight pipe and the outer ring surface of the annular base form a whole, a groove is formed in the inner ring surface of the annular base, and balls are placed in the groove.

Preferably, the grooves are annular grooves, the balls are arranged in the annular grooves in a circle, and one third of the outer surfaces of the balls are exposed out of the annular grooves.

Preferably, the grooves are spherical crown-shaped grooves, and the plurality of spherical crown-shaped grooves are uniformly arranged at intervals in multiple rows; and balls are placed in the spherical crown grooves.

Preferably, the two ends of the protection sleeve units are provided with connecting ports which are respectively an internal thread port and an external thread port, the internal thread ports are matched with the external thread ports, and the protection sleeve units are connected end to end through the connecting ports.

The beneficial effects are that: the utility model discloses a protective case unit, every unit include sleeve pipe straight tube, fold pipe, and the end to end adaptation of external screw thread port in the sleeve pipe unit accessible is connected according to the length of cable, and fold pipe flexible redirecting, and the angle size of bending can be adjusted as required, solves the cable and turns to the protection problem. The inner wall of the sleeve straight pipe is connected with an annular base, the inner annular surface of the base is provided with a groove, a rolling ball is arranged in the groove, when a cable extends into the protective sleeve, the ball is in contact with the cable, the ball rolls, friction between the cable and the inner wall of the protective sleeve is greatly reduced, and labor intensity of constructors is relieved. When the balls in the sleeve unit are worn or the corrugated pipe is damaged, a constructor can conveniently and quickly detach the corrugated pipe, replace a new sleeve unit and reduce the cost.

Drawings

Fig. 1 is a schematic view of the longitudinal section structure of the present invention;

in the figure: 1-a casing housing; 2-a base; 3-folding the tube; 4-rolling balls.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific examples, but the scope of the present invention is not limited to the following examples. For those skilled in the art, it is within the scope of the present invention to derive the basic modifications of the present invention, which are equivalent to the principles of the present invention, or to substitute the commonly known techniques in the prior art, and to simply change the technical features of the same technical effects, which are different combinations from each other and have the same features, or the same or similar technical effects.

Example 1

As shown in fig. 1, a UPVC cable protection sleeve device includes a sleeve straight tube 1 and a corrugated tube 3, wherein the sleeve straight tube 1 and the corrugated tube 3 are fixedly connected to form a protection sleeve unit; the inner ring surface of the annular base 2 is provided with a groove, and a ball 4 is placed in the groove. In the embodiment, the grooves are annular grooves, the balls 4 are arranged in the annular grooves in a circle, one third of the outer surface of each ball 4 is exposed out of the annular groove, and two thirds of the balls 4 are arranged in the annular grooves, so that the balls 4 are kept in the grooves and cannot fall out of the grooves when the balls 4 roll. Protective case unit both ends establish connection port, be internal thread port, external screw thread port respectively, and this internal thread port and external screw thread port looks adaptation, a plurality of protective case units are through this connection port end to end connection. The corrugated pipe can be connected according to the length of the cable, the direction of the corrugated pipe can be changed in a bending mode, the size of the bending angle can be adjusted according to needs, and the problem of cable steering protection is solved.

Example 2

In this embodiment, the structure of the straight casing pipe 1 and the corrugated pipe 3 is the same as that of embodiment 2, the grooves are spherical crown-shaped grooves, and the spherical crown-shaped grooves are arranged in multiple rows at uniform intervals; and place ball 4 in this spherical crown groove, arrange ball 4 through the multiple spot matrix, the contact point of dispersible ball and cable, the rolling area is bigger, reduces frictional force, and single position ball 4 wears and decreases, and is less to whole influence, reduce cost, extension protective case's life.
