Description

A kind of Telescopic spontoon

Technical field

The utility model relates to a kind of security personnel's equipment, in particular to a kind of Telescopic spontoon.

Background technique

Baton is a kind of defensive weapon being equipped at any time of ensuring public security, and is carried for convenience, now with being all much contraction type Baton, stretch out the fixed form of state substantially there are two types of, one is the clip attachment of similar fishing rod, this sample loading mode by It is easy to retract when axial force, another kind is by the push button fixed form similar to umbrella, but this mode is carrying out It is easy to accidentally touch switch when fight, baton is retracted.And it cannot still bear too big axial force.

Utility model content

The problem of for above-mentioned background technique, the utility model provide a kind of Telescopic spontoon.

The technical solution of the utility model are as follows:

A kind of Telescopic spontoon is equipped with set rod, spiral cover and the core rod of handle including tail portion, and core rod section is positive polygon Shape A, tail end are additionally provided with the limit section that section is greater than regular polygon A, and one is provided between the core rod close to limit section part directly Diameter is not more than the lock ring of regular polygon A inscribed circle；Be provided with section in the set rod and limit save matched first sliding groove, section with The matched second sliding slot of core rod；The portion of screwing, jam plate and trepanning are set gradually among the spiral cover, offered among the jam plate with The identical lockhole of regular polygon A, the trepanning diameter are not less than the circumscribed circle of regular polygon A.

Further, the number of edges of regular polygon A is 5-8 item.

Further, spiral cover is engaged by screwing the bulge loop being arranged in portion with the concave ring that rod top side face opens up is covered.

Further, inclined limited step transition is set between core rod and limit section, and sliding with second in first sliding groove The limiting block of respective shapes is set between slot.

Further, the diameter of lock ring is equal to regular polygon A inscribed circle diameter.

Further, trepanning diameter is not less than the circumscribed circle of regular polygon A.

Further, handle appearance is covered with anti-skidding cladding, and both ends are equipped with limiting block.

The utility model has the beneficial effect that

The utility model structure is simple, by spiral cover can execution, and its core rod section be polygon, stretching It will not rotate when doing well, be locked secondly by jam plate, it, will not be because of by Vertical Square relative to modes such as clips To power just withdraw in set rod, guarantee its stability used, it is last its only by lockhole and perfectly aligned core rod when could receive It returns in set rod, and using the mode of rotation, relative to push type unlocking manner, its reliability is higher, and only people is intentional It withdraws, since unexpected a possibility that withdrawing is very small in use process.

Specific embodiment

Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other It can be combined with each other.

As shown in figs. 1-7:

A kind of Telescopic spontoon is equipped with set rod 2, spiral cover 3 and the core rod 4 of handle including tail portion, and 4 section of core rod is positive Polygon A, tail end are additionally provided with the limit section 42 that section is greater than regular polygon A, open between the core rod 4 close to 42 parts of limit section There is a diameter to be not more than the lock ring 41 of regular polygon A inscribed circle；Section and limit section 42 matched the are provided in the set rod 2 One sliding slot 21, section and the matched second sliding slot 23 of core rod 4；The portion of screwing 34, jam plate 32 and rotation are set gradually among the spiral cover 3 Hole 31, lockhole 33 identical with regular polygon A is offered among the jam plate 32, and 31 diameter of trepanning is not less than regular polygon The circumscribed circle of A.

When contraction state such as Fig. 2: core rod is contracted in first sliding groove and second sliding slot completely, at this time the lockhole 33 of spiral cover with Core rod top is staggered, so core rod cannot be pierced by out of lockhole, has been locked in set rod 2.

Stretching state such as Fig. 1: lockhole 33 is aligned, then by rotation spiral cover 3 with 4 top of core rod (or second sliding slot 23) Whipping covers rod 2, and core rod is stretched out from lockhole 33 at this time, completes to limit with 21 intersection of first sliding groove when limit section slides to second sliding slot 23 Position, lock ring 41 is located at the position of jam plate 32 at this time, continues rotation spiral cover and the section of lockhole 33 and set rod 2 is staggered, jam plate 32 Part will screw in lock ring 41, and core rod is locked.Slight amount core rod 3 when recycling rotates spiral cover, when core rod 3 and lockhole pair Qi Shi, core rod can be taken in set rod, rotate spiral cover again after the completion of income and the shape of lockhole and core rod is staggered.

Specifically, the number of edges of regular polygon A is 5-8 item.

Specifically, spiral cover 3 is engaged by screwing the bulge loop being arranged in portion 34 with the concave ring that 2 top side face of rod opens up is covered, still It is also possible to the other ways such as screw thread.

Specifically, be arranged inclined 43 transition of limited step between core rod 4 and limit section 42, and in first sliding groove 21 and the The limiting block of respective shapes is set between two sliding slots 23, inclined limited step 43 with and limiting block cooperate and can not only play limit The effect of position and positioning a, moreover it is possible to elastic force backward is provided when covering rod and being in stretching state, increase for set rod and pre-tighten Power.

Specifically, the diameter of lock ring 41 is equal to regular polygon A inscribed circle diameter, this is can to guarantee jam plate outside lock ring 41 The maximum gauge that edge rotates freely, at this moment the cross-sectional area at lock ring 41 is maximum, that is, its structural strength is maximum.

Specifically, 31 diameter of trepanning is equal to the circumscribed circle of regular polygon A, this is will not the interference of core rod 4 when spiral cover 3 rotates The minimum diameter arrived, trepanning wall thickness are maximum.

Specifically, being not easy to slip when in order to use, 1 appearance of handle is covered with anti-skidding cladding 12, and both ends are equipped with limiting block 13。

The embodiments of the present invention is explained in detail in conjunction with attached drawing above, but the utility model is not limited to be retouched The embodiment stated.For a person skilled in the art, right in the case where not departing from the utility model principle and spirit These embodiments carry out a variety of change, modification, replacement and modification, still fall in the protection scope of the utility model.
