Detailed Description

The present invention will now be further described with reference to the accompanying drawings and detailed description.

As shown in fig. 1 to 4, a mechanical telescopic baton comprises a large tube 1, a middle tube 2, a small tube 3 and a metal unlocking rod 4 which are sleeved in sequence from outside to inside. The grip of the large tube 1 is covered with a rubber jacket 5 to increase friction and comfort. The head end of the small tube 3 is fitted with a metal blade 6 (by interference fit or threaded engagement). Damping limiting structures are arranged among the large pipe 1, the middle pipe 2 and the small pipe 3, drum disc locking structures 7 are arranged at the tail ends of the middle pipe 2 and the small pipe 3, annular grooves 11 and 21 are formed in the inner walls, close to the head ends, of the large pipe 1 and the middle pipe 2, the annular grooves 11 and 21 are used for being matched with the drum disc locking structures 7 to achieve locking, so that the middle pipe 2 and the small pipe 3 are prevented from being thrown out and retracted accidentally, an unlocking button 8 is arranged at the tail end of the large pipe 1, and the unlocking button 8 is used for driving the metal unlocking rod 4 to move so as to unlock a locking state and enable the baton to retract.

Specifically, the damping and limiting structure comprises an inner damping gap adjusting ring 91 and an inner limiting steel ring 92 embedded on the inner wall of the large pipe 1 and the middle pipe 2, and an outer damping gap adjusting ring 93, a first outer limiting steel ring 94, a second outer limiting steel ring 95 and a plurality of buffer rings positioned between the first outer limiting steel ring 94 and the second outer limiting steel ring 95 embedded on the outer wall of the middle pipe 2 and the small pipe 3. The inner damping clearance adjusting ring 91 is close to the head end and the outer damping clearance adjusting ring 93 is close to the drum locking structure 7. The gap adjusting

rings

91 and 93 can effectively solve the problem that a gap between the tube body of the baton commonly used at present shakes through the inner and outer damping. The inner spacing rings 92 are located between the annular grooves 11, 21 and the inner damping gap-adjusting ring 91, and the first outer spacing ring 94 is located close to the outer damping gap-adjusting ring 93 and defines the plurality of cushion rings on the middle tube 2 and the small tube 3 together with the second spacing ring 95. The second limiting steel ring 95 is used for being matched with the inner limiting steel ring 92, so that the middle pipe and the small pipe can be effectively prevented from being thrown away accidentally, and the safety of the spontoon is improved.

In the illustrated embodiment, the plurality of cushion rings includes three nylon cushion rings 96 and two rubber seal rings (O-rings) 97 arranged alternately. The nylon buffer ring 96 and the rubber seal ring 97 can increase the air tightness of the baton body, so that the baton forms a tighter whole.

As shown in fig. 2, 4 and 5, the drum dish locking structure 7 may include a drum dish mounting bracket 71, a male drum disk 72, a female drum disk 73 and two springs 74. The drum mounting bracket 71 is threadably engaged on the rear ends of the middle tube 2 and the small tube 3, has a circular tube shape, and is provided with diametrically opposed drum mounting grooves 711. The male drum disc 72 and the female drum disc 73 are respectively installed in the two drum disc installation grooves 711, and the ring 721 of the male drum disc 72 is inserted between the upper and lower rings 731 of the female drum disc 73. The inner diameters of the

rings

721 and 731 are equal to or slightly larger than the diameter of the metal unlocking lever 4. The spring 74 is installed between the male disc 72 and the female disc 73, so that the male disc 72 and the female disc 73 can be clamped in the annular grooves 11 and 21, and the middle tube 2 and the small tube 3 can be locked. Specifically, the male and

female drum disks

72 and 73 are provided with spring mounting holes in which the springs 74 are mounted. By pressing the unlocking button 8, the metal unlocking lever 4 is inserted into the upper and

lower rings

721 and 731 of the male drum disk 72 and the female drum disk 73, and the male drum disk 72 and the female drum disk 73 are disengaged from the annular grooves 11 and 21, so that the middle pipe 2 and the small pipe 3 can be retracted.

In this embodiment, as shown in fig. 2 and 4, the guide 31 is further installed at the end of the drum disk mounting bracket 71 on the small pipe 3, and the guide 31 has a tapered hole to facilitate the metal unlocking rod 4 to be inserted into the ring 721 of the male drum disk 72 and the upper and lower rings 731 of the female drum disk 73.

As shown in fig. 2 and 4, the unlock button 8 may include a tail cap 81, a spring 82, a button 83, and a positioning post 84. The tail cover 81 has a cylindrical shape with an open tail end and a through hole at the head end, and the button 83 is installed in the tail cover 81. The positioning post 84 is movably inserted into the through hole, the tail end thereof is fixed to the button 83 (in threaded engagement), and the head end thereof is fixedly connected to the metal unlocking rod 4 and the diameter thereof is larger than the through hole. Therefore, by pressing the push button 83, the metal unlocking lever 4 can be driven to be inserted into the ring 721 of the male drum disk 72 and the two upper and lower rings 731 of the female drum disk 73, and unlocking is achieved. The spring 82 is sleeved on the positioning column 84, one end of the spring abuts against the button 83, and the other end of the spring abuts against the tail cover 81. Thus, the button 83 can be automatically reset.

While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
