Abstract

The utility model relates to a positioner mainly used for positioning two mutually sheathed metal tubes of different diameters, and the metal tubes can be relatively pulled out or retracted. The positioner is composed of a precession screw bolt and a dilation screw nut, wherein, the precession screw bolt is composed of three parts: a push-and-pull bolt, a tapered spiral organ and a fixed section connected with an inner tube. The periphery of the dilation screw nut is provided with at least two grooves: one is in full length, and the other one is in 2/3 length. The push-and-pull bolt is sheathed in the hole of the dilation screw nut, and the head of the push-and-pull bolt is slightly larger than the hole of the screw nut. The utility model has the advantage that the inner and the outer tubes positioned can not slip and have a good positioning effect.

Description

A kind of flexible rod positioning work piece
The utility model relates to a kind of positioning work piece.
The positioning work piece of flexible rod is mainly used in two kinds of different-diameters, socket mutually, can pulls out the location of the metal tube of indentation relatively.As the telescopic clothes airing rod of stainless guiding principle of the prior art, its structure is by 2 to 3 joint Stainless Steel Tube sockets in twos, and is when being pulled to extreme length, easy to use; When contracting, be convenient to collection to minimum length.After Stainless Steel Tube was elongated, therefore the energy fixed length between the two joint Stainless Steel Tubes, needed locate with positioning work piece.Existing positioning work piece is the eccentric circle structure, when the shortcoming of this structure is the location, skids location difficulty easily.
The utility model provides a kind of new Ying's flexible thick stick positioning work piece.
The utility model is achieved in that a kind of flexible rod positioning work piece is made of precession bolt and expanding nut two-part.Described precession bolt is made up of three parts, is respectively push-and-pull bolt, cone screw device and the holding part that is connected with interior pipe.Described expanding nut periphery vertically has at least two grooves, and wherein one is total length, and another is 2/3rds length.The push-and-pull bolt is enclosed in the hole of expanding nut, and its head is slightly larger than the hole of expanding nut.
The utility model advantage is: can not skid good positioning effect during the location between the inner and outer pipes.
Accompanying drawing: be the structural representation of the omission inner and outer pipe of model utility.
The most preferred embodiment of a kind of flexible rod positioning work piece of the utility model is to be made of precession bolt 1 and expanding nut 2 two-part.Precession bolt 1 is made up of push-and-pull bolt 3, cone screw device 4 and holding part 5 three parts that are connected with interior pipe.Described expanding nut 2 peripheries vertically have three grooves 6, and wherein one is total length, and another is 2/3rds length.Push-and-pull bolt 3 is enclosed in the hole of expanding nut 2, and its head is slightly larger than the hole of expanding nut 2.When the utility model used, because push-and-pull bolt 3 is in the hole of expanding nut 2, and head was slightly larger than the hole of expanding nut 2, so when inner and outer pipe relatively moves, manage propelling in promptly or when pulling out, expanding nut 2 can be free to slide within interior pipe.Yet when interior pipe precession because the effect expanding nut 2 of cone screw device 4 expanded, make its with outer tube within the resistance increase of wall, so inner and outer pipe can not move again.When interior pipe screwed out, because cone screw device 4 is screwed out, expanding nut 2 was restored, make its with outer tube within the resistance minimizing of wall, can relatively move again between the inner and outer pipe.

Claims (1)

1. a flexible rod positioning work piece wraps and expands inner and outer pipe, it is characterized in that: also be connected with the precession bolt on the interior pipe, also be provided with movably expanding nut within the outer tube; Described precession bolt is made up of three parts, is respectively push-and-pull bolt, cone screw device and the holding part that is connected with interior pipe; Described expanding nut periphery vertically has at least two grooves, and wherein one is total length, and another is at least 1/2nd length; The push-and-pull bolt is enclosed in the hole of expanding nut, and its head is slightly larger than the hole of expanding nut.
