Abstract
The utility model relates to a special plastic conduit for a sliding contact line, which comprises a casing and slots, wherein the casing with double layers is made of engineering flame-retardant PVC materials. A netted supporting structure formed by connecting a plurality of supporting sheets is arranged between an inner layer and an outer layer of the casing; four slots are respectively arranged on the left side and the right side of the inner layer of the casing; two symmetric sealing strip grooves are arranged on the bottom side of the casing; and zero line double-color marked lines are arranged on the surfaces of the bottoms of two sides of the outer layer of the casing. The special plastic conduit has the advantages that the conduit has low-temperature resistance, high-temperature resistance and oxidation prevention; the netted structure of the conduit not only can greatly improve firmness of the conduit, but also greatly lightens the self-weight of the conduit, reduces cost and facilitates lifting of installation personnel and control when in installation; and the sealing strip grooves additionally arranged on the conduit enable sealing modes to be more diversified and more suitable for various complicated working conditions.
Description
Technical field
The utility model relates to a kind of trolley special plastic conduit.
Background technology
The present domestic conventional trolley conduit that uses generally is monochromatic conduit, do not have zero line or ground wire indication graticule,, just have a kind of indication graticule of color yet than the operating position of standard, double-colored indicateing arm wire conduit market at home is in blank at present, only relies on European import; Compare with the trolley conduit of external similar specification, external similar catheter center is apart from generally between 20mm-25mm; The conduit of domestic other producer generally can't seal, perhaps can only be single install rubber weather strip additional.
The utility model content
The purpose of this utility model provides a kind of trolley special plastic conduit, and purpose is that the network structure by conduit increases its robustness, reduces its required cost.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of trolley special plastic conduit, comprise housing and wire casing, described housing is the double Shell of engineering flame-proof PVC material, be provided with the mesh-supported structure that is connected to form by some support chips between described housing internal layer and the skin, described housing internal layer left side and right side respectively are provided with two wire casings, the bottom side of housing is provided with two seal strip grooves of symmetry, and the surface of outer field two side bottoms of housing is provided with the double-colored graticule of zero line.
The beneficial effects of the utility model are: low temperature resistant, high temperature resistant, anti-oxidation, the mesh-supported structure can not only improve the solidness of conduit itself greatly, the weight of conduit own is alleviated greatly, reduce cost, the control when also being convenient to installation personnel handling and installation; Conduit adds the seal strip groove of putting makes sealing means variation more, adapts to various complex operating environment more.
