Abstract

The utility model discloses a quick locking connector for a light telescopic pipe, which consists of a handle and a conical nut, wherein a step-shaped through hole is arranged in the handle; a big hole at the upper end of the handle is used for adhering and fixing a thick pipe; a small hole at the lower end of the handle is used for locking a thin pipe which can move axially; the appearance of the upper end of the handle is elliptic; the appearance of the lower end of the handle is conical; taper threads are made on the external surface of a conical part; three breaches are distributed lengthways and uniformly and made at the conical part; a conical hole is arranged in the conical nut; and inner taper threads are made in the conical hole. When the conical nut is screwed at the lower end of the handle, the handle and the thin pipe can be locked gradually under the action of the radial force generated on a conical surface. The quick locking connector for the light telescopic pipe has the beneficial effects of simple structure and convenience in use. Compared with the prior art, the quick locking connector for the light telescopic pipe can effectively protect the thin pipe, and the service life of the thin pipe is prolonged.

Description

Light-duty telescopic pipe fast fastening joint

Technical field

The utility model relates to a kind of joint of telescopic pipe, relates to a kind of light-duty telescopic pipe fast fastening joint specifically.

Background technique,

Telescopic pipe is a kind of purposes pipe structure very widely, it is by outside that is enclosed within another root of the thin-walled tube more than two or two, there is lock-on connection to connect each other, be characterized in that several extra heavy pipe and sub being nested together of overlapping of tubule that length is short make its volume little so at ordinary times, in light weight, be easy to carry, during use with they one one pulling out and coupling together with lock-on connection, thereby obtain longer pipe to reach the requirement of use.What at present, the tubing of telescopic pipe used mostly is thin-wall stainless steel, plastics, glass fibre reinforced plastics etc.The lock-on connection that uses has the screw of employing fastening, and there also have the mode of utilizing conical surface extruding steel ball or rubber ring to carry out to be fastening, and its shortcoming is to use after a period of time the outer surface of the flexible pipe of damage easily, makes telescopic pipe flexible not smooth, and influence is used.

The model utility content

The purpose of this utility model is exactly in order to remedy above-mentioned the deficiencies in the prior art, and a kind of light-duty telescopic pipe fast fastening joint is provided, and it can effectively not damage tube surface with telescopic pipe locking.

For achieving the above object, the technical solution adopted in the utility model is: a kind of light-duty telescopic pipe fast fastening joint, form by a handle and tapered cup nut, the two is injection molded by engineering plastics, wherein, the inside of handle is a stepped ramp type through hole, the upper end of stepped ramp type through hole is a macropore, the lower end is an aperture, macropore extra heavy pipe that is used to be adhesively fixed of upper end, the aperture of lower end is used to lock axially movable tubule, and handle upper end profile is oval, and the lower end profile is conical, outer surface at tapering part is shaped on tapered thread, and vertically uniformly in the tapered portion office being shaped on three gap that are used to change the lower end hole diameter, tapered cup nut inside is cone shape hole, is shaped on inside tapered thread in the cone shape hole.When tapered cup nut is screwed in handle, at its lower end, under the radial force effect that conical surface produces, can gradually handle and tubule be locked.

Using method of the present utility model is: after extracting tubule out a part from extra heavy pipe, hold handle on the other hand, the tight tapered cup nut of another hand-screw can connect together with handle extra heavy pipe with the locking of tubule.

The beneficial effects of the utility model are: simple in structure, easy to use, tubule is with easy access in extra heavy pipe and lock-on connection, and coupling mechanism force is strong, and compared with prior art it can effectively protect tubule, prolongs the working life of tubule.
