Description
Technical field
This utility model is related to cable pipe equipment, refers specifically to a kind of metallic cable protection pipe sleeve.
Background technology
Cable is the wire product for transmitting electric energy, the signal of telecommunication and realizing electromagnetic energy conversion.Cable generally by transmission electric power or
The cable core of the signal of telecommunication and the sheath composition for playing protection, insulating effect.Lead in/out during cable laying at building, tunnel, building
Need to use cable protection pipe during the place such as plate and wall, wherein be most widely used with metallic cable protection pipe especially, because of the gold
Category cable protection pipe is more resistant, corrosion-resistant, and the performance such as resistance to compression, tension is good, more robust, therefore service life is longer.
To avoid being scratched during cable penetration protecting pipe, it is desirable to protection pipe mouth of pipe impulse- free robustness and sharp corners, and require gold
Category pipe must reliable ground.Guarantee metal pipe mouth impulse- free robustness and sharp corners, to the requirement on machining accuracy of protection metal pipe compared with
Height, high processing costs, and be inconvenient to process；And existing earthing method is typically the welding ground connection on the outer wall of protection metal pipe
Terminal or the method for increasing anchor ear, the former can damage and will carry out anti-corrosion to the zinc coat in metal coating pipe outer wall, after
Person easily send, and earthing effect is not good.
The content of the invention
Technical problem to be solved in the utility model is the present situation for prior art, there is provided a kind of ground connection is well, no
Anticorrosive coat on the outside of protection metal pipe can be destroyed and be easy to the metallic cable protection pipe sleeve processed.
This utility model solve the technical scheme that adopted of above-mentioned technical problem for：The metallic cable protection pipe sleeve, bag
Include the cylinder being connected on metal coating pipe port, it is characterised in that the cylinder includes the loudspeaker of the inner wall smooth being sequentially connected
Section, changeover portion and the linkage section for connecting the metal coating pipe port, the side wall of the linkage section are provided with radial direction screw,
Ground terminal is threaded on the radial direction screw.
The cross section outline of the linkage section is preferably hexagonal structure, with convenient use spanner installation sleeve.
It is preferred that the changeover portion is the necking part of cylinder, facilitate hand-held operation.
It is preferred that the coning angle of the loudspeaker section is 85 °～95 °.The structural cable threading space is big, and resistance is little, and conveniently adds
Work.
Preferably, the coning angle of the loudspeaker section is 90 °.
In above-mentioned each scheme, the connected mode between linkage section and protection metal pipe can have various, preferably, the company
The internal perisporium for connecing section is provided with the female thread being mutually threadedly coupled with metal coating pipe port.The structure is easy for installation and connects steady
Gu.
The ground terminal is to be additionally provided with pad between bolt or screw, and the ground terminal and the linkage section.
Compared with prior art, metallic cable protection pipe sleeve ground provided by the utility model is good, reliable, and not
Anticorrosive coat on the outside of sleeve and protection metal pipe can be destroyed；It is bell-mouthed to design the processing for facilitating protection metal pipe, changeover portion
Design is convenient for assembly and hand-held operation during threading, the convenient connection with protection metal pipe of design of linkage section, and be easily guaranteed that
Machining accuracy, it is to avoid be scratched when cable wears, reduces processing cost.
