Abstract
The utility model relates to a shrinkage sealing cap contains sealing cap main part and stay tube, and the one end at the stay tube is overlapped to the sealing cap main part after the external force expansion, the stay tube is the heliciform, is provided with on the other end of stay tube and takes a percentage, the mutual adhesion of homogeneous phase between each circle spiral of stay tube, all be provided with a spinal branch vaulting pole on each circle spiral of stay tube, the central line of bracing piece is perpendicular with the central line of sealing cap main part, the utility model discloses the shrinkage sealing cap of scheme, each circle of its stay tube all is provided with a spinal branch vaulting pole on spiral, and the central line of bracing piece is perpendicular with the central line of sealing cap main part, guaranteed shrinkage sealing cap when the storage, the stay tube receives sheathed tube radial pressure and is offset by the bracing piece, avoids the stay tube to produce the emergence of deformation scheduling problem.
Description
Technical field
The utility model relates to a kind of cold-shrinking sealing cap, the cold-shrinking sealing cap that particularly a kind of support effect is good.
Background technology
Cold-shrinking sealing cap is made up of sealing cap main body and support bar, and sealing cap main body is sleeved on one end of support bar after external force expansion, and sealing cap main body is silicon rubber cap, and during normality, the cap mouth diameter of silicon rubber cap is less than the diameter of power cable end; Cold-shrinking sealing cap structure is simple, has good waterproof and dampproof performance, does not need to get angry, easy for installation, is used for the water-tight of power cable; But in use, in order to reduce the extraction resistance of stay pipe, the spiral slit adhesion intensity of stay pipe is designed to be less, but this stay pipe is when storing for a long time, its radial pressure being subject to sealing cap main body can produce distortion, even the situation of adhesion position separation, causes it to become waste product.
Utility model content
The utility model object provides to overcome the deficiencies in the prior art the cold-shrinking sealing cap that a kind of support effect is good.
For achieving the above object, the technical solution adopted in the utility model is: a kind of cold-shrinking sealing cap, comprises sealing cap main body and stay pipe, and sealing cap main body is enclosed within one end of stay pipe after external force expansion; Described stay pipe in the shape of a spiral, the other end of stay pipe is provided with tap, adhesion mutually between each circle spiral of stay pipe; Each circle spiral of described stay pipe is provided with a support bar, the center line of support bar and the central axis of sealing cap main body.
Preferably, the multiple support bars on described stay pipe be arranged in parallel along same plane, or interlaced certain angle is evenly arranged.
Preferably, the both ends of the surface of described support bar only have part be connected to the inner side of stay pipe, other parts are as supporting surface.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
The cold-shrinking sealing cap of the utility model scheme, each circle spiral of its stay pipe is provided with a support bar, and the central axis of the center line of support bar and sealing cap main body, ensure that cold-shrinking sealing cap is when storing, the radial pressure that stay pipe is subject to sleeve pipe is offset by support bar, avoids stay pipe to produce the generation of the problems such as distortion.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the schematic diagram of a kind of cold-shrinking sealing cap described in the utility model;
Accompanying drawing 2 is the partial enlarged drawing of a kind of cold-shrinking sealing cap described in the utility model;
Accompanying drawing 3 is the schematic diagram of the another kind of execution mode of a kind of cold-shrinking sealing cap described in the utility model.
Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of cold-shrinking sealing cap described in the utility model, comprises sealing cap main body 1 and stay pipe 2, and sealing cap main body 1 is enclosed within one end of stay pipe 2 after external force expansion; Described stay pipe 2 in the shape of a spiral, the other end of stay pipe 2 is provided with tap 3, adhesion mutually between each circle spiral of stay pipe 2; Each circle spiral of described stay pipe 2 is provided with a support bar 4, the center line of support bar 4 and the central axis of sealing cap main body 1, and multiple support bar 4 be arranged along same plane in parallel.
As shown in Figure 2, the end face of support bar 4 only has the sub-fraction of center be connected to the inner side of stay pipe 2, other parts, only as supporting surface, can make cold-shrinking sealing cap before use like this, very easily support bar 4 is extractd, do not affect the normal use of cold-shrinking sealing cap.
As shown in Figure 3, in another kind of execution mode of the present utility model, multiple support bar 4 can evenly be arranged by interlaced certain angle, and support bar 4 can be made like this to balance out the radial pressure of sealing cap main body 1 equably.
Below be only embody rule example of the present utility model, protection range of the present utility model is not constituted any limitation.The technical scheme that all employing equivalents or equivalence are replaced and formed, all drops within the utility model rights protection scope.
