Abstract
The utility model relates to the improvement of an existing telescopic locking device for circular pipes, which is mainly characterized in that the locking device is composed of a conical threaded rod and a nut. The threaded rod is fixed with one end of a small pipe. A groove and an incision are arranged on the outer side surface of the nut. A convex diameter is arranged inside a big pipe. The improvement of an existing telescopic locking device for circular pipes has the advantages of quick telescopic movements and powerful locking, and is suitable for being used on clothes airing rods, clothes hanging rods, and mops.
Description
The utility model relates to a kind of locking device, relates more specifically to a kind of locking device of retractable big or small pipe.
The flexible pipe of selling on the market generally adopts eccentric wheel structure to be stretched and locks.This structure, though stretching speed is very fast, eccentric wheel is little with big inner tube wall area of contact, thereby locking force is not enough, tries to shirk responsibility easily.
The purpose of this utility model is to provide a kind of both stretching speeds fast, locks firm pipe telescopic locking device again.
Design of the present utility model is achieved in that a kind of pipe telescopic locking device, is made up of conical screw, nut, has a kerf on the outer side surface of nut, and screw rod is fixedlyed connected with an end of tubule, and a protruding footpath is set in the bassoon.
The utility model is because nut and screw rod coupling, the inwall surface of contact of nut and bassoon is bigger, thereby has good locking effect, and because the otch on the nut places the protruding footpath in the bassoon, lock after can directly being pushed into the appropriate location, thereby stretching speed is very fast.
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model nut schematic representation
As Fig. 1, Fig. 2, by this locking device that conical screw 1, nut 2 are formed, screw rod 1 is fixed with an end of tubule 4, has a kerf 5 and groove 7 on the nut 2, welding one protruding footpath 6 in the bassoon 3, and the inwall of nut 2 is inverted cone, nut 2 and screw rod 1 coupling.
During use, nut 2 is placed on the screw rod 1, and the protruding footpath 6 in otch on the nut 25 or the groove 7 aligning bassoons pushes tubule 4, and during to desired location, rotation bassoon 3 or tubule 4 make nut 2 continuous spreadings, thereby makes bassoon 3 and tubule 4 lockings.
