Abstract

The utility model relates to a telescopic spontoon, which comprises an outer sleeve, a middle sleeve, a core rod, a rod head, a end cover and a clamp spring for clamping and fixing the core rod. The telescopic spontoon is characterized in that the outer sleeve is a rod sleeve for lengthening two rods ridden in a middle seat; the outer upper end of the core rod is provided with the rod head. A complete lengthened spontoon is formed by utilizing the centrifugal knockout press of the rod head, and the cooperation of the end outer sleeve, the middle sleeve and the rod head of the core rod. When required, the telescopic spontoon can extended for achieving the effect of portability. The utility model is used for ensuring safety.

Description

Telescopic baton

The utility model relates to the police, security personnel use baton, refers in particular to a kind of outer likeness in form electric billy, the mechanical type that can extend automatically or shrink, scalable baton.

What now, the implement of police of police, security personnel's usefulness used in a large amount of occasion is baton.Baton divides two kinds, and a kind of is the electric billy that can produce high-tension electricity, and a kind of is a metal rod of the similar electric billy of profile, these two kinds of batons drawback in use is significantly, does not allow to use in some occasion as electric billy, and metal baton size is short and small, be difficult for contacting the other side, but carry still inconvenient.

The purpose of this utility model provides a kind of being easy to carry, and has the scalable baton of certain deterrent force.

The purpose of this utility model is achieved in that telescopic baton, and it comprises overcoat, middle cover, core bar, bar head, end cap and fixes the jump ring of core bar; It is characterized in that: overcoat is that built-in two lengthenings of hollow overlap and core bar promptly with the bar cover, and the outer upper end of core bar is the bar head.

Above-mentioned design utilizes the centrifugal knockout press of bar head, relies on the cooperation of overcoat, middle cover and core bar termination to form a complete lengthening baton, in case of necessity, can extend, and has reached effect easy to carry.

Below by accompanying drawing the utility model is described further again:

Fig. 1 is a structural representation of the present utility model;

As shown in Figure 1: the utility model comprises overcoat 1, middle cover 2, core bar 3, bar head 4, end cap 5 and fixes the jump ring 6 of core bar 3; It is characterized in that: overcoat 1 is middle cover 2 and core bar 3 for built-in two lengthenings of hollow with the bar cover, and core bar 3 outer upper ends are bar head 4.Wherein, middle cover 2 also is a ducted body, its upper end is set as tapered cone 7, and core bar 3 lower ends are made as and the supporting flaring Taper Pipe 8 of the tapered cone 7 of middle cover 2, middle cover 2 lower ends are set as flaring Taper Pipe 9, and overcoat 1 upper end is set as and the supporting tapered cone 10 of the flaring Taper Pipe 9 of middle cover 2, flaring Taper Pipe 9 by cover 2 in tapered cone 10 outer being enclosed within, tapered cone 7 outer being enclosed within on the flaring Taper Pipe 8 of core bar 3 of middle cover 2, reach core bar 3, in cover 2 both built-in in overcoat 1, can protrudingly extend again in case of necessity, promptly core bar 3, middle cover 2 and 1 three parts of overcoat rely on the cooperation of two groups of taper seats to form a complete lengthening baton.Be weight reduction, core bar 3 is set as ducted body, and wherein the taper hole of the flaring Taper Pipe 8 of core bar 3 lower ends inserts jump ring 6, and jump ring 6 is fixed in the end cap 5.Wherein, overcoat 1 lower end is provided with internal thread, and end cap 5 is provided with the external screw thread with the engagement of overcoat 1 internal thread.And overcoat 1 outside wall surface and end cap 5 outside wall surface are with the smooth shape in footpath.When needs use baton, hold overcoat 1 and brandish (getting rid of whiplike), bar head 4 and core bar 3 are protruding by the power that holds that its gravity and centrifugal inertia overcome jump ring 6, in 3 times conical surfaces of core bar contact on the cover 2 during taper hole, cover 2 continues protruding together in the drive, in the middle of 2 times conical surfaces of cover when contacting on the overcoat 1 taper hole, centrifugal inertia becomes above-mentioned two groups of tapered sleeves locking tightly separately a length and reaches original lengthening baton more than a times.

When needs are packed up, hold overcoat 1 hard things such as bar head 4 aligning ground, body of wall are vertically exerted oneself, when core bar 3, middle cover 2 were return in the overcoat 1 successively, jump ring 6 had inserted in the taper hole of core bar 3 tail ends, and it is fixed, and finished and collected action.

Claims

1, telescopic baton, it comprises overcoat, middle cover, core bar, bar head, end cap and fixes the jump ring of core bar; It is characterized in that: overcoat is that built-in two lengthenings of hollow overlap and core bar promptly with the bar cover, and the outer upper end of core bar is the bar head.

2, telescopic baton as claimed in claim 1, it is characterized in that: wherein, middle cover also is a ducted body, its upper end is set as tapered cone, and the core bar lower end is made as the flaring Taper Pipe supporting with the tapered cone of middle cover, middle cover lower end is set as the flaring Taper Pipe, and outer set upper side is set as and the supporting tapered cone of the flaring Taper Pipe of middle cover.

3, telescopic baton as claimed in claim 1, it is characterized in that: wherein, core bar is set as ducted body.

4, telescopic baton as claimed in claim 1 is characterized in that: wherein the taper hole of the flaring Taper Pipe of core bar lower end inserts jump ring, and jump ring is fixed in the end cap.
