Abstract

A sliding aid for cable tube penetration is suitable for the tube penetration construction of cable and wire in the installation of electric appliance. The sliding aid is composed of balls (1), a retainer (2) and a core ring (3), when in use, the sliding aid is sleeved on the outer diameter of a cable, iron wires are bound firmly with the cable along positioning grooves on two sides of the retainer (2) and enter a pipe along with the cable, and the balls (1) which are uniformly distributed on the circumference of the sliding aid roll between the cable and the inner pipe wall along with the movement of the cable, so that the friction between the outer diameter of the cable and the inner wall of a penetrating pipe is reduced. The sliding aid solves the problems of difficult pipe penetration and breaking of the cable, and is suitable for being used in the electric industry installation department.

Description

Slide-helper for cable passing through pipe

The utility model relates to a kind of cable pipe instrument ┈ cable pipe slide-helper.

Poling problem to cable in the electrical equipment installation, method commonly used is to place iron wire in cable tube in advance, during poling, after cable end connects, cable is hauled out from pipe with iron wire, sometimes cable is longer, elbow is arranged again midway, and resistance to sliding increases in the pipe, makes cable haul out very effort, exert oneself also can make cable breakage when big.So smooth for poling sometimes, often caliber is increased, this certainly will increase investment cost again.

The purpose of this utility model is to provide a kind of convenient and flexible installation, processes easyly, and cost is low, poling labour-saving cable pipe slide-helper.

The measure that the utility model is taked is: on the retainer of annular ball is housed, the episphere of ball is on the retainer excircle, can contact with the poling inner tubal wall in the use, lower semisphere is in the retainer circumferential apertures, circumferential apertures can be the ball location, be wrapped in the core ring on the retainer, can be as the mandrel of ball rotation, during use, can be according to treating the poling cable length, along cable successively equidistantly cover load onto several slide-helpers, and be fixed on the outside diameter of cable with iron wire, because ball equal and opposite in direction, can remain cable in the poling centralized positioning, so also be not subjected to drag effects in pipe bent position, this has loaded onto wheel around giving cable, having significantly reduced the friction between cable and tube wall, is desirable poling instrument.In addition, poling Guan Jingke presses 1.5 times of selections of the outside diameter of cable.

Below in conjunction with the description of drawings embodiment:

Fig. 1 faces partial structurtes figure for slide-helper.

Fig. 2 is a slide-helper retainer section A-A amplification profile.

Fig. 3 is slide-helper, retainer section B-B amplification profile.

Fig. 4 is the slide-helper end view, slide-helper service position figure.

The explanation of each sequence number among the above figure:

1, ball 2, retainer 3, core ring 4, iron wire

5, iron wire 6, cable tube 7, cable.

The utility model is mainly by ball (1), retainer (2), core ring (3), form, retainer (2) is used plastic injection-moulded shaping, have the circular hole that is equally spaced on its circumference, along having location notch on the center circumferential of this circular hole, core ring (3) twines along this groove, and the lower semisphere of ball (1) is positioned in the circumferential apertures, episphere is given prominence to outside the circumference of retainer (2), have breach on the circumference of retainer (2), in order to compensation and the gap of cable when fastening, both sides have location notch, link to each other with cable in order to tie up iron wire, core ring (3) substitutes with iron wire, when slide-helper is contained on the outside diameter of cable, ball (1) does not contact with cable, only rotates with the friction of cable tube inwall.

Claims

1, a kind of by ball (1), retainer (2), the cable pipe slide-helper that core ring (3) is formed, the ball (1) that is through on the core ring (3) that is characterised in that of the present utility model, one hemisphere is put into the uniform corresponding circumferential apertures of annular retainer (2), the quantity of ball and corresponding circumferential apertures is more than 3, the ball top portion and the cable surface of ball (1) leave the gap, another hemisphere is given prominence to outside the circumference of retainer (2), can contact with the poling inwall, the core ring (3) that ball (1) center is installed with is located in the circumferential registration groove of retainer (2), ball (1) can rotate around core ring (3), retainer (2) both sides have ties up location notch, and retainer (2) endoporus can cooperate with outside diameter of cable suit.

2, slide-helper according to claim 1 is characterized in that retainer (2) by the plastics manufacturing, and ball (1) is by the rigid plastics manufacturing, and core ring (3) uses general iron wire.
