Abstract
An insulation sheath for high-voltage cable which is made of flexible insulative materials and is provided with a locking mechanism for coiling and locking the sheath is characterized in that the locking mechanism comprises a protuberance arranged on the external surface of the interior part of the sheath and a groove matching with the protuberance which is arranged on the internal surface of the exterior part of the sheath. The sheath of the utility model is applicable for high-voltage cable. Two protuberances are arranged on the external surface of the interior part of the sheath. Two grooves matching with the protuberances are arranged on the internal surface of the exterior part of the sheath. The utility model is applicable for the cable with small internal diameter when two protuberances are simultaneously inserted into two grooves. When one of two protuberances is inserted into the groove, the utility model is applicable for the cable with big internal diameter.
Description
Technical field:
The utility model relates to a kind of high-voltage cable insulating protective sleeve.
Background technology:
For solving the problem that transmission line exposes, Chinese patent has proposed " the open-air cable protective sleeve of a kind of composite material " for No. 02238150.3.In this technical scheme, protective sleeve has certain wall thickness, and flexible; Joint, two ends after the protective sleeve bending is provided with a pair of double buckle, it can be locked.Above-mentioned protective sleeve can solve the problem that transmission line exposes with the cable envelope within it.But the protective sleeve of said structure has the following disadvantages:
1, the joint, two ends after the protective sleeve bending is provided with double buckle, and after the double buckle locking, the gap location of double buckle exists the part cable to expose, and makes above-mentioned protective sleeve be not suitable for using on high-tension cable.
2, because the internal diameter of protective sleeve can not be adjusted, a kind of protective sleeve can only be applicable to a kind of cable of specification.Make that the applicability of protective sleeve is undesirable.
Summary of the invention:
The purpose of this utility model is: provide a kind of applicability good high-voltage cable insulating protective sleeve.The utility model is achieved through the following technical solutions:
A kind of high-voltage cable insulating protective sleeve; protective sleeve is made by flexible insulating material; protective sleeve is provided with the retaining mechanism that protective sleeve is reeled and locked; it is characterized in that: described retaining mechanism comprises: be located at the projection of the inner outer surface of protective sleeve, the protective sleeve outer inner is provided with the groove that matches with projection.After adopting said structure to make retaining mechanism locking of the present utility model, the cable periphery is all coated, and makes protective sleeve of the present utility model be adapted at using on the high-tension cable.
In the utility model, the inner outer surface of described protective sleeve is provided with two projectioies, and the protective sleeve outer inner is provided with two grooves that match with projection.Insert two grooves simultaneously when two projectioies, protective sleeve of the present utility model is applicable to the less cable of internal diameter.When having only a projection to insert groove, protective sleeve of the present utility model is applicable to the bigger cable of internal diameter.Protective sleeve of the present utility model can be applicable to the cable of different size, and applicability is better.Certainly, the inner outer surface of the utility model protective sleeve also can be established projection more than two, the protective sleeve outer inner be provided with protruding two of matching with upper groove.It can improve the applicability of protective sleeve.
Description of drawings:
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model embodiment 1 retaining mechanism place generalized section.
Fig. 3 is the utility model embodiment 2 generalized section when being suitable for the less cable of internal diameters.
Fig. 4 is the utility model embodiment 2 generalized section when being suitable for the big cable of internal diameters.
Embodiment:
In conjunction with Fig. 1, shown in Figure 2: the high-voltage cable insulating protective sleeve of present embodiment, protective sleeve 1 are made by flexible insulating material, and protective sleeve is provided with the reel retaining mechanism 5 of locking of protective sleeve.Retaining mechanism comprises: be located at the projection 2 of the inner outer surface of protective sleeve, the protective sleeve outer inner is provided with the groove 3 that matches with projection.After the protective sleeve locking of present embodiment, cable 4 peripheries are all coated, and make protective sleeve be adapted at using on the high-tension cable.
In conjunction with Fig. 3, shown in Figure 4: in the present embodiment, the inner outer surface of protective sleeve is provided with two projectioies 2, and the protective sleeve outer inner is provided with and protruding two grooves 3 that match.The protective sleeve of present embodiment can be applicable to the cable of different size.
Claims (2)
1, a kind of high-voltage cable insulating protective sleeve; protective sleeve is made by flexible insulating material; protective sleeve is provided with the retaining mechanism that protective sleeve is reeled and locked; it is characterized in that: described retaining mechanism comprises: be located at the projection of the inner outer surface of protective sleeve, the protective sleeve outer inner is provided with the groove that matches with projection.
2, high-voltage cable insulating protective sleeve according to claim 1; It is characterized in that: the inner outer surface of described protective sleeve is provided with two or more projectioies, and the protective sleeve outer inner is provided with two or more grooves that match with projection.
