Abstract
The utility model provides a line tail protective sheath, includes metal connecting piece (1), plastic protective sheath (2) and pipeline assembly part (3), the one end and plastic protective sheath (2) the looks joint of metal connecting piece (1), the other end and pipeline assembly part (3) of metal connecting piece (1) form threaded connection. The utility model has the characteristics of wear resistance, ageing resistance, bending resistance roll over and anti -corrosion performance stronger, can be effectively to the cable surface carrying out the anti -aging and wear -resistant wiping protection etc.
Description
[technical field]
The utility model relates to cable protection field, particularly relates to a kind of line tail protective sleeve.
[background technology]
The line tail protective sleeve that metal connecting piece combines with plastic protective sleeve is the Novel cable protection product that a kind of alternative traditional sebific duct protection or metal protect spring.It is poor that traditional metal protects the anti-wear performance of spring or sebific duct protection product, anti-aging, bend resistance and corrosion resistance, can not carry out anti-aging and anti-wear protection to cable surface.In addition, the material that traditional sheath product is selected is poor, can not carry out available protecting to cable.
[summary of the invention]
The utility model is intended to solve the problem, and provides a kind of and prevent that coiled pipe line end and main frame from getting loose, available protecting bends repeatedly and cause communication cable to be lost and effectively improve the line tail protective sleeve of product reliability.
For achieving the above object; the utility model provides a kind of line tail protective sleeve; comprise metal connecting piece, plastic protective sleeve and main frame assembly parts, one end and the clamping of plastic protective sleeve phase of described metal connecting piece, the other end of described metal connecting piece is formed with main frame assembly parts and is threaded.
Described metal connecting piece is the column of hollow; one end of described metal connecting piece is provided with the plastic protective sleeve connecting portion stretching out and formed; the ring surface of this plastic protective sleeve connecting portion is provided with the buckling groove with plastic protective sleeve clamping, and the madial wall of the other end of described metal connecting piece is provided with internal thread.
Described plastic protective sleeve is the housing be made up of one section of plane and one section of inclined-plane; the inclined-plane of described plastic protective sleeve is laid with multiple rectangular through-hole preventing plastic protective sleeve from fractureing; the planar inner of described plastic protective sleeve is provided with the interior edge extending internally and formed, the plastic protective sleeve connecting portion of described metal connecting piece stretch into plastic protective sleeve planar inner and with plastic protective sleeve in along mutual clamping.
Be provided with external screw thread outside the link of described main frame assembly parts, this external screw thread is formed with the internal thread of metal connecting piece and is threaded.
The external diameter of the plastic protective sleeve connecting portion of described metal connecting piece is less than the external diameter of metal connecting piece.
The internal diameter on the interior edge of described plastic protective sleeve is less than the external diameter of plastic protective sleeve.
The length of described metal connecting piece is identical with the length of plastic protective sleeve.
Described metal connecting piece is made up of copper or aircraft aluminum.
Described plastic protective sleeve by nylon material or polythene material injection molded.
The beneficial effects of the utility model are, it efficiently solves existing metal, and to protect the anti-wear performance of spring or sebific duct protection product, anti-aging, bend resistance and corrosion resistance poor, can not carry out the technical problem such as protecting to cable surface.The structural design that the utility model matches by adopting screens and back-off; can prevent in use firmly excessive and cause product structure to come off; thus effective protection is through the cable of tubular body; therefore; greatly reduce the maintenance probability that the design problem because of product brings; virtually improve product reliability energy and useful life, and reduce the maintenance cost in product later stage.
