The telescopic spontoon comprises an outer rod, an inner rod, a transmission pull pipe and an elastic component, wherein the inner rod is provided with a free end and a locking end; the locking end extends in the outer rod; at least one groove transmitting pull pipe is arranged on the outer peripheral surface of the locking end; the inner wall of the transmitting pull pipe inwards extends to form at least one inclined surface; at least one second through hole is formed in the inner side of each inclined surface in the transmitting pull pipe; when the transmitting pull pipe slides towards an opening end of the outer rod, balls are squeezed by the inclined surfaces, enter a groove and then are fastened in the groove, so that the locking end is locked; and when the transmitting pull pipe slides towards a closed end of the outer rod, the balls are separated from the groove, so that the locking end is pushed by a component and then moves towards the opening end. The telescopic spontoon is simple in structure, is light and handy, is convenient to operate and long in service life, and is portable; the telescopic spontoon can be circularly used telescopically and repeatedly; and moreover, the beating resistance is high.
Description
Technical field
The utility model relates to a kind of baton, particularly the baton of the scalable variation of a kind of length.
Background technology
Baton is divided into two kinds of structures conventionally, and a kind of length specification is fixed, and another kind comprises telescoping mechanism.The fixing baton of length specification defect is in actual use larger, and for example, oversize being not easy to of length carried, too short have reduced attack distance.And known baton with stretching structure is the alert tool that China one line public security cadres and police must join, it is widely used, aggressive strong, immaculates in defence, and both can effectively prevent act of violence, also can keep off protect, Fang Kan, anti-rod hit etc.Existing retractable spontoon is made up of parts such as rubber lever, rear pipe, middle pipe, front pipe, bulb and locking devices mostly.Effect by centrifugal force when use throws away middle pipe and front pipe, the hand-tight rubber lever of holding while packing up, and bulb is downward, vertically hits hard thing and once unclamps first flexible lock, hits immediately for the second time second flexible lock rushed open, and just can successfully shrink baton.The method that adopts this contraction baton is more violent owing to shrinking while clashing into strength, not only easily damages baton internal structure, but also can damage the bulb of baton, directly the good looking appearance degree of baton is exerted an influence, and greatly shortens the service life of baton.

The specific embodiment
Below in conjunction with the specific embodiment, the utility model is described in further detail:
Outer bar 1, it is hollow structure, described outer bar has blind end 2 and openend 3, the sidewall of described outer bar offers at least one first through hole 4, and described outer bar 1 has the stopper section 12 of the described transmitting trombone slide 9 of outward extending restriction to described blind end 2 sliding paths at the rear side of described transmitting trombone slide 9, take the radiation direction of interior bar 5 as front, after with its rightabout being, each the first through hole 4 is strip, and each ball is also positioned at the first through hole 4, and each groove 8 aligns with one end of the first through hole 4;
Transmitting trombone slide 9, the inwall of described transmitting trombone slide extends internally and forms at least one inclined-plane 10, the inside of described transmitting trombone slide 9 also forms at least one second through hole 11 in the inner side on each inclined-plane 10, each the second through hole 11 limits the rolling path of a ball between an inclined-plane 10 and a groove 8, described transmitting trombone slide 9 is slidably set in the outside of described outer bar 1, the inside of launching trombone slide 9 described in the present embodiment is formed with an endless member 13 in the inner side on described inclined-plane 10, described endless member 13 has three the second through holes 11, each the second through hole 11 is along the radially extension of described endless member 13, angle between adjacent two the second through holes 11 is 60 degree.
Elastic component (not shown), its one end is connected to the blind end 2 of described outer bar 1, and the other end is connected to the positive stop end of described interior bar 5;
Wherein, each groove 8 is positioned at the inner side of first through hole 4, when described transmitting trombone slide 9 slides to the openend 3 of described outer bar 1, each ball is subject to the extruding on described inclined-plane 10 to enter and be buckled in a groove 8, thereby by described locking end 7 lockings, and described elastic component (not shown) is subject to the extruding of described locking end 7 and described blind end 2 in compressive state, when described transmitting trombone slide 9 slides to the blind end 2 of described outer bar, each ball departs from each groove 8, thereby make described locking end 7 moved to described openend 3 by the promotion of described elastic component (not shown).
Under battery, extend internally and form inclined-plane 10 by the compression elasticity that is pressed in ball in groove 8 and overcomes elastomeric element by the inwall of transmitting trombone slide 9, interior bar 5 is remained static.
While stating Telescopic spontoon in the use, first hold and hold transmitting trombone slide 9 outside bar 2 rear direction and pull and launch trombone slide 9.Now, ball is buckled in to inclined-plane 10 in the groove 8 of interior bar 5 and leaves ball.Like this, battery lower inclined plane 10, ball, groove 8 are broken with the dynamic balance between elastomeric element, that is: ball is due to the dependence having lost inclined-plane 10, under the effect of elastomeric element elastic force, be extruded groove 8, make thus interior bar 5 lose the buckle of ball and penetrate under the effect of elastomeric element elastic force.Thus interior bar 5 is ejected to outer bar 1.
In the time of openend 3 place of the outer bar 1 of walking to of interior bar 5, first conical surface 14 and second conical surface (not shown) of locking end 7 lock, in bar 5 stop at this position.
