Abstract
The utility model discloses a kind of for connecting the connecting sleeve of penetration pipe, and by being equipped with annular groove on the outer wall of casing, which correspondingly forms annular protrusion on the inner wall of casing；When adjacent two sections of penetration pipes are inserted in casing, due to the presence of annular protrusion, two sections in casing of penetration pipe is set to be stuck, casing cannot be to the mobile longer distance of a certain section of penetration pipe, so that the relative movement between casing and penetration pipe be avoided to keep the electric wire between adjacent two sections of penetration pipes or cable exposed；Meanwhile the inner surface of casing is coated with a powder bed, powder bed has the function of fire-retardant, insulation, when for preventing the insulating layer breakage on electric wire or cable, touching and causing to leak electricity on the inside of casing.The connecting sleeve of the utility model can effectively solve problem of the existing technology.
Description
Technical field
The utility model relates to a kind of connecting sleeves more particularly to a kind of for connecting cable or the connector sleeve of conduit
Pipe.
Background technique
The bottom of EMU is provided with many components, and needs to be equipped with electric wire or cable connection between these components.
For traffic safety, need to put on not only heat-resisting but also flame-resistant insulation penetration pipe on the outside of these electric wires or cable, but because of zero
The arrangement of component is extremely complex, and the length of each section of penetration pipe, direction is caused to be different from, so needing to connect between each section of penetration pipe
It picks up and.Previous way usually welds two sections of adjacent penetration pipes, but the penetration pipe after welding cannot be torn open
It unloads, once the electric wire or cable in penetration pipe, which are damaged, could replace threading tube damage, in addition electric wire or electricity
When the connection line of cable needs to adjust, it is also desirable to tube damage will be threaded, it is inconvenient in the extreme for operator.
In the prior art, operator is changed to cover a upper straight tube in the interface of two sections of adjacent penetration pipes, compares in this way
It is more convenient more rewire, cable or change route.But vibration can be generated in the course of emu operation, and shaking can make directly
Both ends penetration pipe in pipe relatively moves, it is easy to can get loose, cause security risk；Moreover, existing set is threading
There is no the effects of flame-resistant insulation for straight tube on pipe, when the electric wire insulation layer between the penetration pipe of both ends is exposed, are easy to touch
Encounter straight tube and causes the safety accidents such as electric leakage.
Utility model content
The purpose of the utility model is to provide a kind of for connecting the connecting sleeve of penetration pipe, which can be effective
It solves the above problems.
To achieve the goals above, the technical solution of the utility model is:
It is a kind of for connecting the connecting sleeve of penetration pipe comprising: sleeve；The outer wall of described sleeve pipe is equipped with an annular
Groove, the annular groove and described sleeve pipe are coaxially disposed, and the annular groove forms convex annular in the inner wall of described sleeve pipe
It rises；The inner surface of described sleeve pipe is coated with a powder bed.
As a kind of specific embodiment, described sleeve pipe is anodic oxidation aluminum pipe.
Further, the inner surface of described sleeve pipe is frosting.
As a kind of specific embodiment, the material of the powder bed includes resin, curing agent, fire retardant and weatherability end
Carboxyl polyester.
Further, the material of the powder bed further includes pigments and fillers and titanium dioxide.
As a kind of specific embodiment, the height of the annular protrusion is not less than the thickness of penetration pipe.
As a kind of specific embodiment, hard alloy skeleton, the hard alloy bone are arranged in the annular groove
Frame is for preventing the annular protrusion from being hit when connecting penetration pipe and deforming.
Compared with prior art, the utility model has following technical effect that
The connecting sleeve for being used to connect penetration pipe of the utility model comprising sleeve, by the outer wall of casing
Equipped with annular groove, which correspondingly forms annular protrusion on the inner wall of casing；When adjacent two sections of penetration pipes are inserted
When in casing, due to the presence of annular protrusion, two sections in casing of penetration pipe is made to be stuck, casing cannot be worn to a certain section
The mobile longer distance of spool, so that the relative movement between casing and penetration pipe be avoided to make the electricity between adjacent two sections of penetration pipes
Line or cable are exposed；Meanwhile the inner surface of casing is coated with a powder bed, powder bed has the function of fire-retardant, insulation, is used for
When preventing the insulating layer breakage on electric wire or cable, touches and cause to leak electricity on the inside of casing.
Further, casing is anodic oxidation aluminum pipe, and oxygen-proof property is more preferable；Moreover, the inner surface of casing is frosting,
Frosting can make the adhesiveness of powder bed more preferable, can effectively increase the Use Limitation of connecting sleeve.
Further, in order to reach insulation, flame retardant effect increase the weatherability of powder bed, the material packet of powder bed while
Include resin, curing agent, fire retardant and weatherability terminal carboxyl polyester.
Further, in order to increase the durability and hardness of powder bed, powder bed further includes pigments and fillers and titanium dioxide.
Further, in order to preferably limit movement of the penetration pipe in connecting sleeve, the height of annular protrusion is not less than
The thickness of penetration pipe；Meanwhile in order to avoid by penetration pipe be inserted into connecting sleeve when, caused since impact force is excessive annular protrusion and
The deformation of annular groove is arranged with hard alloy skeleton in annular groove.
In order to better understand and implement, according to the present invention will be described in detail below with reference to the accompanying drawings.
Detailed description of the invention
Fig. 1 is the radial cross-section of the connecting sleeve for connecting penetration pipe of the utility model；
Fig. 2 is the axial sectional view of the connecting sleeve for connecting penetration pipe of the utility model；
Fig. 3 is the structural schematic diagram for the connecting sleeve that the utility model is connected with hard alloy skeleton.
