Abstract
The utility model discloses a positioning mechanism of an extension tube which includes an external pipe which is pierced with an internal pipe. The utility model is characterized in that the end part of the external pipe is provided with a sleeve pipe which is provided with a hole; the side wall of the external pipe is provided with a hole being corresponding to the sleeve pipe; the two holes are provided with a positioning block which is contacted with the external wall of the internal pipe; the sleeve pipe is provided with a pressing plate which is provided with a cam which is contacted with the positioning block; the pressing plate is connected with the sleeve pipe by a shaft which is arranged on the cam; the internal pipe is provided with a position limit block which is matched with the positioning block; the positioning mechanism adopted by the utility model can make the connection between the internal and external pipe is extremely firm without easy to loosen, thus good positioning effect can be reached.
Description
Technical field
The utility model relates to a kind of positioning means of telescopic pipe.
Background technique
The positioning means of telescopic pipe commonly used, be to comprise the outer tube fixed base that is installed in outer tube one end, be equipped with a base on the outer tube fixed base, base can rotate on fixed base, be combined with a stock on the base, the stock upper sleeve through has a kinematic nest, kinematic nest also can be rotated thereupon when stock rotated, kinematic nest is provided with a projection, one end of the contiguous kinematic nest of projection is provided with eccentric segment, eccentric mass is installed on the eccentric segment, and interior pipe is interspersed in pipe fixed base in being provided with of outer tube one end, manages in the fixed base in projection is located in.The telescopic pipe of said structure connects positioning means when rotating base, can drive stock by base rotates, making stock drive kinematic nest synchronously rotates, deflection by the eccentric segment on the kinematic nest, and promote the inwall that eccentric mass is resisted against outer tube, reach the purpose of inner and outer pipe location by the frictional force that produces between eccentric mass and the inwall.Yet the telescopic pipe of this structure connects the detent force quantity not sufficient that positioning means produced, and makes the inner and outer pipes of location loosening phenomenon occur easily, and does not also occur utilizing the telescopic pipe positioning means of positioning block and cam pressing cooperation at present.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of and locatees that strength is big, the telescopic pipe positioning means of good positioning effect.
The technological scheme that its technical problem that solves the utility model adopts is:
A kind of positioning means of telescopic pipe, comprise an outer tube, be equipped with interior pipe in the outer tube, it is characterized in that sleeve pipe being installed in the end of outer tube, described sleeve pipe is provided with the hole, the sidewall of outer tube is provided with and the corresponding hole of sleeve pipe, be provided with positioning block in two holes, positioning block contacts with outer wall of inner tube, on the described sleeve pipe pressing plate is installed, pressing plate is provided with cam, and cam contacts with positioning block, pressing plate is connected with sleeve pipe by the axle that is installed on the cam, and described interior pipe is provided with the limiting stopper that matches with positioning block.
As the improvement of the above-mentioned mode of execution of the utility model, the sidewall that described interior pipe contacts with positioning block is provided with some teeth.
As the further improvement of the above-mentioned mode of execution of the utility model, the bi-side of described pressing plate are provided with striped.
The beneficial effects of the utility model are: positioning means of the present utility model adopts positioning block and cam structure combining, telescopic pipe is when being positioned mechanism's locking, positioning block is pressed on the outer wall of interior pipe by cam, thereby make the combination between the inner and outer pipes very firm, be difficult for becoming flexible, thereby can reach good locating effect; The sidewall that interior pipe contacts with positioning block is provided with some teeth, thereby makes positioning block tightr with combining of outer wall of inner tube, is difficult between the inner and outer pipes being pulled; Bi-side at pressing plate are provided with striped, can prevent to produce sliding phenomenon between the hand and pressing plate when unclamping pressing plate, so that unclamp pressing plate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a three-dimensional exploded view of the present utility model;
Fig. 2 is the schematic perspective view of the utility model at releasing orientation;
Fig. 3 is the schematic perspective view of the utility model at lock state.
Embodiment
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 1, Fig. 2, shown in Figure 3 be a kind of positioning means of telescopic pipe, comprise an outer tube 1, in the outer tube 1 be equipped with in pipe 2, the cross section of inner and outer pipes shape roughly triangular in shape is beneficial to position relatively stable between the inner and outer pipes.End at interior pipe 2 is equipped with tail plug 14, and the other end is equipped with the fixedly fixture block 15 that is used for fixing garden instrument; The one end cover of outer tube 1 is transferred and is provided with handle 11, the other end is equipped with sleeve pipe 3, sleeve pipe 3 is provided with a hole 12, the sidewall of outer tube 1 is provided with and sleeve pipe 3 corresponding holes 13, in two holes, be provided with positioning block 4, positioning block 4 contacts with the outer wall of interior pipe 2, and pressing plate 5 is installed on sleeve pipe 3.
As shown in the figure, pressing plate 5 is provided with cam 6, and cam 6 contacts with positioning block 4,12 both sides, hole on sleeve pipe 3 are provided with two relative projections 16, projection 16 and cam 6 are provided with axis hole 17, and axle 7 is installed in the axis hole 17, and pressing plate 5 is connected with sleeve pipe 3 by the axle 7 that is installed on the cam 6.
Telescopic pipe is when being positioned mechanism's locking like this, and positioning block is pressed on the outer wall of interior pipe by cam, thereby makes the combination between the inner and outer pipes very firm, is difficult for becoming flexible, thereby can reaches good locating effect.
With reference to Fig. 1, interior pipe 2 is provided with a spacing hole 18, and limiting stopper 8 is installed in the spacing hole 18, and when telescopic pipe was drawn back certain position, limiting stopper 8 withstood on a side of positioning block 4, thereby can prevent from interior pipe is pulled out from outer tube.
As shown in the figure, the sidewall that interior pipe 2 contacts with positioning block 4 is provided with some teeth 9, thereby makes positioning block tightr with combining of outer wall of inner tube, is difficult for more between the inner and outer pipes being pulled.
With reference to Fig. 1, be provided with striped 10 in the bi-side of pressing plate 5, utilize striped 10 can increase frictional force between pressing plate and operator's the hand, thereby can prevent from when unclamping pressing plate, to produce sliding phenomenon between the hand and pressing plate, conveniently to unclamp pressing plate.
The above only is preferred embodiment of the present utility model, can not limit protection domain of the present utility model with it.So long as the equalization of doing according to protection domain of the present utility model changes and modify, all should still belong in the scope that the utility model contains.
