For this reason, some manufacturers have developed a telescopic baton that allows users to carry it easily and does not cause unnecessary wear due to wearing such self-defense equipment. Questioning and trouble.

At present, the telescopic baton is composed of a plurality of tubular bodies, as shown in Fig. 1, which is one of the telescopic batons disclosed in U.S. Patent No. US20130150167, which is respectively provided by an outer tubular body 11 The tube body 12 and the inner tube body 13 are combined, and the tube bodies 11, 12, and 13 are hollow, wherein the diameter of the outer tube body 11 is larger than the diameter of the middle tube body 12, wherein The diameter of the tubular body 12 is larger than the diameter of the inner tubular body 13, and the inner tubular body 13 can be condensed into the inner diameter of the intermediate tubular body 12, which can be condensed to the outer tubular body 11 In the inner diameter, when the outer tube body 11 of the telescopic baton 1 is gripped and thrown, the middle tube body 12 and the inner tube body 13 can protrude from the outer tube body 11 and are engaged with each other. When the telescopic baton 1 is subjected to a pressure, the inner tube body 13 and the middle tube body 12 will be sequentially condensed into the inner diameter of the outer tube body 11 to form a short stick shape for use. Collection with belts.

Referring to Figures 1, 2 and 3, the telescopic baton 1 is provided with a plurality of brake mechanisms 14 and a release mechanism 15. Since the brake mechanism 14 has the same structure and action, only the middle tube is followed. The brake mechanism 14 between the body 12 and the outer tubular body 11 is described. Further, the brake mechanism 14 includes two brake blocks 141 and two elastic members 142, and is disposed on the middle tubular body 12 Near the one end of the tube body 12, the middle tube body 12 is provided with symmetrical two-holes 120 at the periphery of one end thereof. The brake block 141 of the brake mechanism 14 can be respectively pivoted to each of the through holes 120, and can pass through the perforations. a reciprocating displacement, and a release hole 140 is defined in each of the two brake pads 141, and the release holes 140 are overlapped. Each of the elastic members 142 is disposed between the inner edges of the brake pads 141. Both ends of the component 142 can respectively generate a force on each of the brake pads 141 to push the brake pads 141 away from each other.

In addition, the release mechanism 15 is assembled at one end of the outer tube body 11. The release mechanism 15 includes a button 151 and a release lever 152. The button 151 is assembled to one end of the release lever 152, and one end of the release lever 152 can Extending into the outer tube body 11, when the user throws the telescopic baton 1 so that one end of the middle tube body 12 is displaced toward the other end of the outer tube body 11, when the brake pads 141 are displaced to the outside When the other end of the tube body 11 is used, the brake pads 141 are pushed by the elastic member 142, and protrude from the through hole 120 to be inserted into the locking groove of the other end of the outer tube body 11, so that the middle portion The tubular body 12 and the outer tubular body 11 can maintain a stable positioning state.

Although the telescopic baton 1 can be conveniently switched between the "extended state" and the "closed state" for the user to carry and use, in fact, the telescopic baton 1 is still not perfect enough in the operation, and For the industry, the design of the brake mechanism 14 and the release mechanism 15 is not conducive to controlling the production cost and assembly efficiency, respectively, as follows:

(1) Problem of actuation stability: Since the brake pads 141 are connected to each other only by the elastic members 142, and the elastic members 142 have toughness instead of a rigid member, they cannot always maintain a horizontal state. Therefore, during the displacement of the brake mechanism 14, the brake pads 141 can move with each other, that is, during the movement, the brake pads 141 may not remain in the same horizontal displacement, thus, A locking groove in which one of the brake pads 141 is fitted to the other end of the outer tubular body 11 will be caused, but the other brake block 141 is not embedded in the locking groove of the other end of the outer tubular body 11, so that The telescopic baton 1 cannot be stably held in a long stick shape, or the telescopic baton 1 cannot be completely extended into a long stick shape and folded into a short stick shape, thereby affecting the stability of the telescopic baton 1.

(2) Production cost and efficiency problem: In addition, since the brake block 141 has to pass through the through hole 120 in the middle pipe body 12, the outer pipe body 11 can be stably positioned outside the middle pipe body 12, so When the middle tube 12 is produced, the manufacturer must machine the perforation 120 on the middle tube 12 by a process such as piercing, punching or cutting, and the processing procedure not only greatly affects the production process of the telescopic baton 1 And the yield, even dragging the assembly time of the baton 1 and possibly destroying the overall structural strength of the middle tube 12, so the design of the brake mechanism 14 is not conducive to cost control for the operator.

To this end, the inventor thought, can it be improved for the conventional brake mechanism? In order to solve the stability problems that may occur in the conventional telescopic batons, at the same time, the production efficiency and assembly convenience of the telescopic batons are improved, so that the operator can mass produce the batons of good quality in a shorter time, therefore, how Designing a brand-new telescopic baton is an important issue that the present invention is intended to solve here.

In view of the inconvenience of the conventional telescopic batons in production and assembly, the inventors have relied on years of rich practical experience and professional knowledge, after continuous testing, research and development, and considering various feasibility in practical operations, finally The invention discloses a telescopic baton which can improve assembly convenience and stability, and can improve the production efficiency of the telescopic baton through a positioning device which is more compact and easier to produce and assemble.

One end of each of the brake blocks is respectively provided with an extending portion, and each of the extending portions is movably positioned at the receiving portion. In the slot so that the brake pads can be held On the two corresponding sides of the positioning frame, and A release hole is defined in each of the extending portions corresponding to the through hole; each of the elastic members is positioned between the positioning frame and each of the braking blocks to be displaced to the outer tube at one end of the inner tube The elastic restoring force of the elastic members can drive the braking blocks to move away from the positioning frame in a state corresponding to the position of the locking groove, so that the other end of each braking block can be outwardly Expanding and embedding into the recessed recess, so that the other end of the inner tubular body can be stably positioned outside the outer tubular body; and the release device is activated to bring the release rod toward the inner tubular body In a state in which one end is displaced, the release rod can be sequentially inserted into the through hole and the receiving groove, and pushes against the inner wall surface of the extending portion corresponding to the releasing hole, so that the braking blocks are displaced toward the positioning frame. And out of the snap groove. In this way, since the positioning device is directly screwed to the inner tube body, the efficiency of assembling the telescopic baton can be effectively improved.

Another object of the present invention is to combine the positioning device and the inner tube body through the design of the first joint portion and the second joint portion, so that the manufacturer does not need to be a telescopic baton as in the prior art when producing the telescopic baton. Therefore, it is necessary to perform processing such as piercing on one end of the inner pipe body, thereby avoiding the problem that the overall structural strength of the inner pipe body is affected, and the durability and stability of the telescopic baton are damaged.

For the sake of review, the reviewer can have a further understanding and understanding of the technical principle, structural features and purposes of the present invention.
