Abstract

The utility model discloses a locating device acting on an outer piece and an inner tube being connected with said outer piece including a spring piece in the inner tube. On the active surface of the spring is convexly located a locating pillar and a press-button pillar. The inner tube has a locating through-opening and a press-button through-opening. The locating pillar and press-button pillar on the spring piece can extends out of said locating through-opening and press-button through-opening of the inner tube. Said outer piece is located within the inner tube by the locating pillar. When dismount or configure the locating device, press the press-button pillar to make the active surface draw back bringing along the locating pillar to draw back to separate connection of the locating pillar and outer piece, then dismount or adjujst the outer piece and inner tube, thereby ensuring convenient and safe dismounting and adjustment.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of positioner, it acts between the interior pipe that an outer part and is connected in outer part, it comprises the elastic component of being located in the interior pipe, convex with reference column and button post on the active face of this elastic component, offer positioning through hole and button pass through hole on the interior pipe; The positioning through hole and the button pass through hole of pipe in reference column on the elastic component and button post can stretch out in respectively under the elastic force effect; Wherein, described outer part is connected in interior pipe by the reference column location.

Described elastic component is a class V-arrangement sheet, and two lateral surfaces of class V-arrangement sheet are respectively stationary plane and active face; Two cylinders that protrude on the active face are defined as reference column and button post respectively.

The described cylinder nearer apart from the V-arrangement openend is reference column, and the cylinder far away apart from the V-arrangement openend is the button post.

The top of described reference column is a hemispherical.

The top of described button post is a hemispherical.

Pipe grafting and interlocking wherein, offer by jack on the outer part in outer part in described, and reference column stretches out in positioning through hole and is inserted in by in the jack.

Described reference column and knob post side by side, this flat cable is parallel to interior tubular axis line.

Described two cylinders and the moulding of elastic component integrated punching.

Described two cylinders welding or riveted joint are fixed in the active face of elastic component.

The beneficial effects of the utility model are:

One, positioner of the present utility model, in dismounting or the adjustment process, user's knob post that press...withes one's finger down earlier, active face retreats and drives reference column and retreats, and the connection between reference column and the outer part is thrown off, and then dismounting or outer part of adjustment and interior pipe, dismantle or easy to adjust, safety, the accident of clip finger can not take place in dismounting or the adjustment process;

Its two, elastic component is class V-arrangement sheet, and is simple in structure, easy to assembly;

Its three, the cylinder nearer apart from the V-arrangement openend is reference column, the cylinder far away apart from the V-arrangement openend is the button post, the knob post is pressed less distance can make reference column produce bigger backway, convenient connection of throwing off between reference column and the outer part;

Its four, described reference column front portion is a hemispherical, pipe and outer part in then the convenient location of reference column connects are convenient to throw off the connection between reference column and the outer part;

Its five, reference column and knob post side by side, this flat cable is parallel to interior tubular axis line, the dismounting or easy to adjust;

Its six, two cylinder and the moulding of elastic component integrated punching, easy to process, cost is low;

Its seven, two cylinder welding or riveted joint are fixed in the active face of elastic component, firmly.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the schematic perspective view of the elastic component of positioner of the present utility model.

Fig. 2 is the schematic perspective view of positioner of the present utility model.

Fig. 3 is the in running order generalized section of positioner of the present utility model.

Fig. 4 is the generalized section that positioner of the present utility model is in unloading process.

The specific embodiment

A kind of positioner, shown in Fig. 2,3,4, it acts on an outer tube 1 and a grafting and interlocking between the interior pipe 2 of outer tube 1.Outer tube 1 offers by inserting hole 11, offers positioning through hole 21 and button pass through hole 22 on the interior pipe 2.

Shown in Fig. 1,3, positioner comprises the V-arrangement elastic components of being located in the interior pipe 23, and this V-arrangement elastic component 3 has stationary plane 31 and active face 32.Stationary plane 31 comprises stiff end and union end, pipe 2 inside in stiff end is fixed in; Active face 32 comprises free end and positioning end, and positioning end is fixed in stationary plane 31 union ends.Wherein, active face 32 under the elastic force effect against interior pipe 2 inner peripheral surfaces.

Shown in Fig. 1,2,3,4, two cylinders that protrude side by side on the active face 32.Wherein, be reference column 321 apart from the nearer cylinder of elastic component 3V shape openend, be button post 322 apart from elastic component 3V shape openend cylinder far away.At active face 32 pipe 2 axis in this flat cable is parallel to during against interior pipe 2 inner peripheral surfaces.Distance between reference column 321 and the V-arrangement openend approximates 1/2nd of distance between knob post 322 and the V-arrangement openend.The front portion of the front portion of reference column 321 and knob post 322 is hemispherical.

In reference column 321 stretches out under elastic component 3 elastic force effects pipe 2 positioning through hole 21 and be plugged in outer tube 1 by inserting hole 11, by reference column 321 interlocking outer tubes 1 and interior pipe 2.

The button pass through hole 22 of pipe 2 in knob post 322 stretches out under elastic component 3 elastic force effects.
