Example 1

As shown in fig. 1 and fig. 2, the present embodiment provides a vertical rod telescoping control mechanism 30, which may include a box structure 100, and a key structure 200 and a retractable pin structure 300 disposed on the box structure 100, and the key structure 200 and the retractable pin structure 300 interact with each other, so that the retractable pin structure 300 can be retracted or extended by pressing the key structure 200, and the retractable pin structure 300 can unlock or lock other structures.

Specifically, the cassette structure 100 may include a cassette base plate 110 and a cassette cover plate 120 covering the cassette base plate 110, wherein the cassette base plate 110 and the cassette cover plate 120 enclose a locking cavity 104 and an unlocking cavity 102 formed to communicate with each other. By arranging the box structure 100 in a structure that the box bottom plate 110 and the box cover plate 120 are mutually covered, the locking cavity 104 and the unlocking cavity 102 are conveniently arranged between the box bottom plate 110 and the box cover plate 120, so that the telescopic pin structure 300 and the key structure 200 are conveniently and correspondingly arranged in the locking cavity 104 and the unlocking cavity 102 respectively.

The locking cavity 104 may be formed by forming a groove in the case bottom plate 110, a groove in the case cover plate 120, or corresponding grooves in both the case bottom plate 110 and the case cover plate 120. Similarly, the unlocking cavity 102 may be formed by forming a groove on the box bottom plate 110, a groove on the box cover plate 120, or corresponding grooves on both the box bottom plate 110 and the box cover plate 120.

In this embodiment, as shown in fig. 3 to fig. 6, the locking cavity 104 may include a bottom plate locking groove 114 formed on the box bottom plate 110, and a cover plate locking groove 124 formed on the box cover plate 120, where the cover plate locking groove 124 and the bottom plate locking groove 114 are correspondingly communicated up and down for accommodating and limiting the key structure 200. Similarly, the unlocking cavity 102 may include a bottom plate unlocking groove 112 formed in the bottom plate 110 of the box body, and a cover plate unlocking groove 122 formed in the cover plate 120 of the box body, and the cover plate unlocking groove 122 and the bottom plate unlocking groove 112 are correspondingly communicated up and down for accommodating and limiting the telescopic pin structure 300. Moreover, the bottom plate locking groove 114 is communicated with the bottom plate unlocking groove 112, and the cover plate locking groove 124 is communicated with the cover plate unlocking groove 122, so that the unlocking cavity 102 is communicated with the locking cavity 104, and the key structure 200 in the unlocking cavity 102 is abutted to the telescopic pin structure 300 in the locking cavity 104.

Furthermore, the key structure 200 can be elastically disposed in the unlocking cavity 102, partially protruding out of the box structure 100, and tightly fit with the retractable pin structure 300. Furthermore, the retractable pin structure 300 may be elastically disposed in the locking cavity 104 and partially protrude out of the box structure 100. Also, when the key structure 200 is pressed, the key structure 200 may reduce a pressing action on the telescopic pin structure 300 to put the telescopic pin structure 300 in a contracted state. By elastically arranging the key structure 200 in the unlocking cavity 102, when the part of the key structure 200 protruding out of the box body structure 100 is pressed, the elastic acting force of the key structure 200 in the unlocking cavity 102 can be overcome, so that the key structure 200 is contracted, the key structure 200 can act on the telescopic pin structure 300 in abutting fit with the key structure 200 in the contraction process, the extrusion force on the telescopic pin structure 300 is reduced, the telescopic pin structure 300 can automatically contract under the action of the elastic force of the telescopic pin structure 300, and the part protruding out of the box body structure 100 is contracted towards the inside of the box body structure 100; when the pressing of the portion of the key structure 200 protruding out of the box structure 100 is released, the key structure 200 will reset under the action of its own elastic force and protrude out of the box structure 100 again, the pressing force of the key structure 200 to the retractable pin structure 300 abutting against it will increase during the resetting process, and the elastic force of the retractable pin structure 300 can be overcome to protrude out of the box structure 100 again.

By arranging the retractable pin structure 300 and the key structure 200 in the box body structure 100, when the key structure 200 is pressed, the squeezing action on the retractable pin structure 300 arranged in the box body structure 100 is reduced to enable the retractable pin structure to contract, so that the retractable pin structure 300 unlocks other structures (such as upright posts) and can perform retractable deformation on the other structures (such as upright posts); when the key structure 200 is no longer pressed, the key structure 200 automatically resets under the action of its own elasticity to push the retractable pin structure 300 to automatically extend out, so that the retractable pin structure 300 can fix other structures (such as a vertical rod) and keep the shapes of the other structures (such as the vertical rod) unchanged. Through using this kind of pole setting control mechanism that stretches out and draws back on the scooter, the accessible is pressed and is loosened button structure 200, and automatic structure to the scooter carries out telescopic control, can change the size of scooter simply, can make it more conveniently carry.

The key reset elastic member 220 can tightly press the key block structure 210 by its own elasticity, and tightly press the retractable pin structure 300 contacting the key block structure 210. When the portion of the key block structure 210 protruding out of the box structure 100 is pressed, the key block structure 200 presses the key return elastic element 220, so that the key return elastic element 220 overcomes the elastic force thereof to contract, and the elastic force of the key return elastic element 220 on the key block structure 210 is reduced, so that the pressing force of the key block structure 210 on the retractable pin structure 300 is reduced, and the retractable pin structure 300 contracts into the box structure 100 under the elastic force thereof, so that the portion of the retractable pin structure 300 protruding out of the box structure 100 contracts into the box structure 100.

Moreover, the key block structure 210 may include a key main block 216 movably disposed in the unlocking cavity 102, and a key cap 212 disposed on the top of the key main block 216, wherein the key cap 212 is located outside the box structure 100, the bottom of the key main block 216 abuts against the key return elastic element 220, and the side of the key main block 216 abuts against the retractable pin structure 300. The shape of the unlocking cavity 102 is matched with the shape of the key main block body 216 correspondingly, so that the unlocking cavity 102 can perform proper limiting and guiding on the key main block body 216. In addition, the key block structure 210 may further include a key link 214 connecting the key cap 212 and the key main block 216, so as to facilitate the key cap 212 protruding from the case structure 100 and to facilitate the transmission of the force acting on the key cap 212 to the key main block 216.
