With the mentioned structure the technical problem of locating which requires plastic connecting piece with female and male thread is solved, the utility model with economical cost saves power in operating.
Description
Technical field:
The utility model relates to the flexible positioning means of inside and outside sleeve structure, particularly a kind of inside and outside sleeve pipe with Telescopic.
Background technique:
In products such as drying rack, plain type wardrobe, the structure of inside and outside telescopic tube is generally adopted.Flexible, locating function by inside and outside sleeve pipe can change the length of product, and then make product strengthen practicability.Flexible, the position structure of existing inside and outside sleeve pipe is usually as shown in Figure 1: outer race solid of pipe A lower end has the plastic fastening B of outside thread B1 in this, and the upper end cover solid of this outer tube C has the plastic fastening D of internal thread D1; The internal thread D1 of this plastic fastening D and the outside thread B1 of above-mentioned plastic fastening B can screw togather mutually.During use, the location after by above-mentioned internal and external screw thread structure telescopic inside and outside sleeve pipe being stretched.But this structure has following defective:
1, this structure need be equipped with a plastic fastening on interior pipe and outer tube, and plastic fastening all needs to offer screw thread, has therefore increased the cost of material and the technology cost of product.
2, this structure needs to rotate multi-turn in flexible location work, could be with internal and external screw thread in conjunction with firm, and therefore the operation of location is also relatively required great effort.
The model utility content:
The purpose of this utility model is to provide a kind of flexible positioning means of inside and outside sleeve pipe newly, and mainly solving existing structure needs two plastic fastenings that have internal and external screw thread respectively could realize the technical problem of location, low, the rapid operation of cost.
For solving the problems of the technologies described above, the utility model is achieved in that
A kind of flexible positioning means of inside and outside sleeve pipe comprises a pipe and an outer tube in one, it is characterized in that: this outer tube upper end is affixed with an end of a plastic fastening; This plastic fastening is to be hollow cylinder, and is provided with the flexible guiding slip groove of interior pipe and the locating groove of connection in barrel, on the outer wall of pipe a guide sliding part that can slide is set in this in above-mentioned guiding slip groove and locating groove.
The flexible positioning means of described inside and outside sleeve pipe is characterized in that: this guide sliding part is one to be fixed on the screw on the outer wall of inner tube.
The flexible positioning means of described inside and outside sleeve pipe is characterized in that: this outer tube upper end is affixed by the internal and external screw thread structure with a plastic fastening one end.
The flexible positioning means of described inside and outside sleeve pipe is characterized in that: flexible guiding slip groove of the interior pipe of this connection and locating groove are L-shaped.
By said structure, the utlity model has following advantage:
1, the utility model structure is compared with structure of the prior art, and only need a plastic fastening, and do not need to process the internal and external screw thread structure, therefore, no matter be that cost of material and technology cost all decrease.
2, the utility model only needs that the guide sliding part on the interior pipe is slipped into locating groove and can finish the location in use, and is than the screw thread location of existing structure, easy to operate, laborsaving.

Embodiment:
See also Fig. 2,3,4, it is the structural representation of flexible positioning means one preferred embodiment of the inside and outside sleeve pipe of the utility model.As shown in the figure: it comprises pipe 1 and one outer tube 2 in; One end of these outer tube 2 upper ends and a plastic fastening 3 is affixed, and ways of connecting can be that these outer tube 2 upper ends and a plastic fastening 3 one ends are affixed by the internal and external screw thread structure.This plastic fastening 3 is to be hollow cylinder, and is provided with the flexible guiding slip groove 31 of interior pipe and the locating groove 32 of connection in barrel, and flexible guiding slip groove 31 of the interior pipe of this connection and locating groove 32 are L-shaped.Should in a guide sliding part 11 that can slide was set on pipe 1 the outer wall above-mentioned guiding slip groove 31 and locating groove 32 in, this guide sliding part 11 is one to be fixed on interior screw of managing on 1 outer wall.
During use, see also Fig. 5: send into guiding slip groove 31 by the guide sliding part 11 on the interior pipe 1, when guide sliding part 11 slides into the bottom of guiding slip groove 31, interior pipe 1 is rotated to counter clockwise direction, to be that guide sliding part 11 slips into locating groove 31, finish the positioning action of inner and outer pipe.More than whole position fixing process only need with 1 rotation of interior pipe once (less than one circle) get final product, the orientation type that will rotate multi-turn than original structure is laborsaving many.
Above-described is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the present patent application claim change and modification, all should be technology category of the present utility model.
