Description

Technical Field

[0001] The utility model relates to the technical field of batons, in particular to a retracting and locking structure of a resistance baton. Background Art

[0002] The baton is generally composed of three sections of tubes. The first section is the striking section, the second section is the middle section, and the third section is the grip section. The taper at the rear end of the striking section, the tapers at both ends of the middle section and the front end of the grip section are used to lock the baton in the expanded state after it is thrown out. It is carried in the retracted state and used in the expanded state. When the baton is in the retracted state, the striking section and the middle section must not fall out at any angle under the action of the gravity of the tube. If they fall out, the lock in the expanded state will be unstable. Therefore, a set of parts structure is required in the retracted state to lock the striking section and the middle section so that they are fixed in the grip section.

[0003] The existing locking structure usually uses two symmetrical spring steel sheets fixed on a circular sheet, which is fixed on the grip section. When the contraction needs to be locked, the hollow tube at the rear end of the striking section is inserted into the spring sheet fixed on the grip section, and the friction between the spring sheet and the tube wall causes it to be locked.

[0004] The locking structure has the following disadvantages: 1. When the impact intensity is high in the unfolded state, the spring sheet is easily broken due to vibration impact; 2. Since the spring sheet is in surface contact with the tube wall, the locking is unstable, affecting the use effect. Utility Model Content

[0017] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0018] like Figure 1-4 As shown, a retracting and locking structure of a resistance baton comprises: a three-section telescopic baton body, which are respectively a striking section 1, an intermediate section 2 and a grip section 3 connected in sequence, wherein the striking section 1, the intermediate section 2 and the grip section 3 are all hollow cylinders, the striking section 1 is inserted into the intermediate section 2 to freely retract and retract, and the intermediate section 2 is inserted into the grip section 3 to freely retract and retract; a tail cover 4 is fixed to the bottom end of the grip section 3, a retaining spring rod 5 is fixed in the tail cover 4; a retaining spring screw 6 is fixed to the bottom end of the striking section 1, a locking retaining spring 7 is fixed in the retaining spring screw 6; the locking retaining spring 7 matches the shape of the retaining spring rod 5.

[0019] The circlip screw 6 is provided with a locking circlip fixing groove 8, and the locking circlip 7 is fixed in the locking circlip fixing groove 8. The circlip rod 5 includes a head 51, a clamping portion 52 and a fixing portion 53, and the head 51, the clamping portion 52 and the fixing portion 53 are connected in sequence; the head 51 is conical, and the clamping portion 52 is provided with an annular clamping groove 54, and the locking circlip 7 is clamped in the clamping groove 54.

[0020] The retaining spring rod 5 and the tail cover 4 are detachably connected, and the retaining spring screw 6 and the striking joint 1 are detachably connected, and both can be specifically designed as threaded connections.

[0021] When the utility model is in operation, when the baton contracts, the striking section 1 drives the middle section 2 to contract together into the grip section 3. Since a locking clip 7 is fixed to the bottom end of the striking section 1, when the bottom end of the striking section 1 moves to the bottom end of the grip section 3, the head 51 of the clip rod 5 passes through the locking clip 7, and the locking clip 7 is fixed in the clamping groove 54 of the clip rod 5 to achieve locking. When the baton is unfolded, since the clamping groove 54 is a groove with an arc surface as the contact surface, the locking clip 7 can be separated from the clamping groove 54 by just swinging the baton. At the same time, since the clamp and the clip rod are in line contact, when they are swung out, the clamp generates elastic force at the moment when the clamp and the clip rod are separated, and the force acting on the three-section telescopic stick body connection structure is greater. After unfolding, the connection is stable and reliable, and the use effect is good.

[0022] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention.
