Abstract
The utility model provides a rotary-type waterproof joint for an electric cable protection pipe. The rotary-type waterproof joint comprises a body, a gasket, a bag-shaped screw cap and a locking nut, wherein an intermediate joint is mounted between the body and the bag-shaped screw cap; a groove I is arranged on an inner wall of one end of the intermediate joint, and a groove II is arranged on an outer wall of an end of the body; the intermediate joint and the body are engaged such that the groove I and the groove II are arranged in correspondence, and stopper rings are arranged inside the grove I and the grove II; the other end of the intermediate joint cooperates with the bag-shaped screw cap and is fixed by the locking nut. An O-shaped ring is arranged at the joint of the intermediate joint and the body. The body has a shape of straight line or curve. The stopper ring is a rubber ring with an opening. The rotary-type waterproof joint for the electric cable protection pipe has good sealing and waterproof properties, and the joint can be freely rotated so as to meet changes of the angle and direction of the electric cable during a use process, thereby providing convenience for use.
Description
Technical field
The utility model relates to a kind of electric wire protection tube joint, and it is free to rotate to be mainly used in waterproof, sealing and joint.
Background technology
Electric wire protection tube joint has been widely used in all trades and professions, such as LED street lamp, beacon, pleasure-boat, industrial equipment, sprinkling truck etc.Its Main Function is to make circuit unobstructed, makes cable keep sealing, and guarantees the class of insulation at cable joint place, and it is moved safely and reliably.If poor sealing not only can leakage of oil cause oil-paper withered, and moisture also can invade cable inside, makes the paper insulation hydraulic performance decline.
Electric wire protection tube joint of the prior art is mostly only considered its waterproof and sealing property, needs to occur the problem that direction changes and reckon without electric wire because using.
Summary of the invention
The purpose of this utility model provides the rotary water joint of a kind of electric wire protection tube; not only have good sealing and water resistance; and joint is free to rotate, satisfies the in use variation of direction and angle of electric wire, brings convenience to use.
The technical solution of the utility model: the rotary water joint of electric wire protection tube; comprise body, packing ring, bag shape nut and locknut; between body and the bag shape nut transition joint is installed; the inwall of the first end of indirect is provided with the groove I; the outer wall of body end is provided with the groove II; transition joint and body docking make groove I and groove II correspondence, are placed with stopper ring in groove I and the groove II, and the other end of transition joint cooperates with a bag shape nut and fixes by locknut.
Be provided with O type circle in transition joint and body joint.
Body is linearity or bending.
Described stopper ring is for being with rubber ring jaggy.
The beneficial effects of the utility model: owing between body and bag shape nut, transition joint is installed, block by stopper ring being placed on be locked in the groove between transition joint and the body, do so on the one hand and can satisfy sealing, can make on the other hand ontological idea of freedom rotate to satisfy actual use needs, and then further lock by locknut; Owing to be provided with O type circle in transition joint and body joint, strengthened sealing property of the present utility model; Body adopts linearity or bending to satisfy the use needs of different angles different directions electric wire; Because stopper ring adopts and is with rubber ring jaggy, the easier locking of blocking that makes between transition joint and the body, thus realize that electric wire protection tube joint is free to rotate.
