Abstract

The utility model relates to a pyrocondensation dactylotheca, including pipe shaft and branch pipe, the pipe shaft is hexagonal light -wall pipe for the cross -section is, the one end of pipe shaft is the blind end, and the other end is the open end, closed end face is last to be equipped with a plurality of independent branch pipes, the branch pipe all along the axial extension of pipe shaft, still be equipped with the separation piece that prevents the branch pipe and draw in in each other between a plurality of independent branch pipes, the separation piece passes through the binder adhesion and is in on the blind end, be equipped with a plurality of branchings on the separation piece, adjacent branch pipe is separated to the branching, be equipped with a series of axially extended line of weakness of pipe shaft of following on the pipe shaft. Through above -mentioned mode, provide a pyrocondensation dactylotheca, it has a good contractility, and dampproofing and waterproofing moreover can effectual protection of cables. Simultaneously, it has add the structure that increases clearance between the branch pipe, can make and be heated evenly, warp unanimously, and the pyrocondensation dactylotheca of this structure is convenient for tear, can not increase the degree of difficulty of dismantlement.

Description

A kind of thermal-shrinkage finger sleeve

Technical field

The utility model relates to cable auxiliary product field, particularly relates to a kind of thermal-shrinkage finger sleeve.

Background technology

Pyrocondensation cable finger sleeve; be commonly called as thermal-shrinkage finger sleeve or pyrocondensation gloves; gain the name because of the palm of the similar people of its shape and finger; crosslinked polyolefin materials and PUR is adopted to be composited; be enclosed within multicore cable core bifurcation, namely heating shrinks, and cable can tightly cling by the PUR of inwall; play waterproof and moistureproof sealing protective effect, outer field irradiated crosslinked polyalkene material can play electric insulation protective action.Such as Chinese utility model patent " a kind of thermal-shrinkage finger sleeve of cable ", application number is 200920103737.0, it discloses pipe shaft and vial, described pipe shaft one end is closed, arm evenly on the Closed End of pipe shaft, wherein, pipe shaft blind end is outside outstanding sphere, and arm is communicated with blind end.This fingerstall has good elasticity, remains to combine closely with cable after installation, stops moisture, guarantees security of operation, reliable.But by using actual conditions, its vial is easy to draw in after pyrocondensation, the gap of adjacent is too small causes material in gap to be heated inequality, impact parcel effect; And its dismounting is also inconvenient, scratches in process and easily damages cable, also can affect personal safety after too tightening up at blade.

Utility model content

The technical problem that the utility model mainly solves is to provide a kind of thermal-shrinkage finger sleeve, and it is reasonable in design, and structure is simple, solves uneven and that distortion the is irregular problem of being heated that gap deficiency between adjacent arm causes, solves the problem disassembling difficulty simultaneously.

For solving the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of thermal-shrinkage finger sleeve, and comprise pipe shaft and arm, described pipe shaft is cross section is hexagonal light-wall pipe; One end of described pipe shaft is blind end, and the other end is openend; Described Closed End is provided with multiple independently arm; Described arm all extends along the axis of described pipe shaft; The barrier blocks preventing arm from mutually drawing in is independently also provided with between arm multiple; Described barrier blocks sticks on described blind end by binding agent; Described barrier blocks is provided with some bifurcateds; Adjacent arm is separated by described bifurcated; Described pipe shaft is provided with a series of along the axially extended line of weakness of pipe shaft.

Preferably, described line of weakness position is from the openend of described pipe shaft and extends to the blind end place of described pipe shaft.

Preferably, described barrier blocks has heat cured organic material to make; The quantity of described arm is at least 2.

The beneficial effects of the utility model are: provide a kind of thermal-shrinkage finger sleeve, and it has good contractility, and waterproof and dampproof, effectively can protect cable.Meanwhile, it has set up the structure increasing gap between arm, and can make to be heated evenly, distortion is consistent; And the thermal-shrinkage finger sleeve of this structure is convenient to tear, the difficulty of dismounting can not be increased.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of thermal-shrinkage finger sleeve of the utility model;

Fig. 2 is the schematic diagram at another visual angle of thermal-shrinkage finger sleeve;

In accompanying drawing, the mark of each parts is as follows: 1, pipe shaft; 2, arm; 3, screw thread; 4, spacer block; 5, bifurcated; 6, line of weakness.

Embodiment

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail, to make advantage of the present utility model and feature can be easier to be readily appreciated by one skilled in the art, thus more explicit defining is made to protection range of the present utility model.

Refer to attached Fig. 1 and 2, the utility model embodiment comprises:

A kind of thermal-shrinkage finger sleeve, comprise pipe shaft 1 and arm 2, described pipe shaft is cross section is hexagonal light-wall pipe, and is also provided with screw thread 3 on the inwall of pipe shaft 1.One end of described pipe shaft 1 is blind end, and the other end is openend; Described Closed End is provided with multiple independently arm 2; Described arm 2 all extends along the axis of described pipe shaft 1; The quantity of described arm 2 is at least 2, and as illustrated in fig. 1 and 2, what adopt in the present embodiment is the example of three arms.The barrier blocks 4 preventing arm 2 from mutually drawing in is also provided with between multiple independently arm 2; Described barrier blocks 4 has heat cured organic material to make.Described barrier blocks 4 sticks on described blind end by binding agent; And described barrier blocks 4 is provided with some bifurcateds 5; Adjacent arm 2 is separated by described bifurcated 5; Therefore, after thermal-shrinkage finger sleeve is sleeved on required cable position, through heating pyrocondensation, gap between its adjacent arm 2 can make the Closed End of pipe shaft also be heated evenly, and arm 2 can not be made too to draw in, since can increase spacing to each other, and be also easy to the separation of arm.Described pipe shaft 1 is provided with a series of along the axially extended line of weakness 6 of pipe shaft 1.The position of described line of weakness 6 is from the openend of described pipe shaft 1 and extends to the blind end place of described pipe shaft 1, this structure is in order to can be for convenience detach, when the fingerstall after pyrocondensation is firmly wrapped on cable, be difficult to disassemble, and use cutter to go to cut open and likely can injure cable, much unnecessary trouble can be caused like this.

The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
