【Detailed ways】

The utility model is a folding structure capable of preventing misoperation. As shown in Figures 1 to 5, the utility model comprises a first swing body 2 with a pair of coupling pieces 1, and is connected between the pair of coupling pieces 1 through a swing shaft 3. The second swinging body 4 and the folding structure 5, in this embodiment, the folding structure is applied to the scooter. At this time, the first swinging body 2 is the pedal of the scooter, and the second swinging body 4 is the scooter. Standpipe (of course, it can also be a fork pipe, etc.). The coupling piece 1 is provided with an unfolding slot 11 and a retracting slot 12 respectively; the outer wall of the coupling piece 1 between the unfolding slot 11 and the retracting slot 12 is the swing axis 3 is the arc-shaped surface 13 at the center of the circle; the second swinging body 4 includes a cylindrical rotating body 44 placed horizontally, the lower end is inserted into the vertical sliding hole 441 of the rotating body 44 and can slide linearly along the sliding hole for a considerable period of time. The vertical rod 45 at the distance of the depth of the card slot; the center of the rotating body 44 is connected between the pair of coupling plates 1 by swinging through the swing shaft 3; the folding structure 5 includes a locking pin 51 and a return spring 52, The middle and upper part of the rotating body 44 and the vertical rod 45 are respectively provided with a bayonet avoidance strip hole 442 and a bayonet circular hole 451 for the bayonet 51 to pass through; the vertical rod 45 is provided with a swing shaft The first avoidance strip hole 454; the return spring 52 is provided in the vertical sliding hole 441 of the rotating body 44 to reset the vertical rod 45 into the vertical sliding hole 441, and the return spring can be a compression spring or Tension spring; after the middle of the bayonet 51 traverses the bayonet circular hole 451 of the vertical rod 45 and the bayonet pin of the rotating body 44 to avoid the bar-shaped hole 442, under the action of the return spring 52, its two ends can move along the The arc surface 13 of the coupling piece 1 can slide down into the corresponding card slot (ie the unfolding card slot 11 or the retracting card slot 12 ) after sliding counter-clockwise or clockwise. When the car is to be folded, pull the vertical rod 45 by hand, so that after overcoming the force of the return spring 52, it slides out a short distance along the vertical sliding hole 441 of the rotating body 44, and the detent 51 will slide away from the coupling piece 1, then you can swing the vertical rod 45 to make it swing clockwise with the rotating body 44 around the swing shaft 3 to fold the car; then, release the vertical rod 45 and continue to fold the car. When the bayonet 51 slides along the arc surface 13 of the coupling piece 1 toward the retracting slot 12; when the bayonet 51 slides into the retracting slot 12, under the action of the return spring 52, the vertical rod 45 rotates along the After the vertical sliding hole 441 of the body 44 slides inward for a short distance and is in place, the folding process of the car is completed. Similarly, when the vehicle is to be unfolded, the vertical rod 45 is pulled outward, so that after overcoming the force of the return spring 52, it slides out a short distance along the vertical sliding hole 441 of the rotating body 44, and the detent 51 will slide away After closing the slot 12 on the coupling piece 1, the vertical rod 45 can be swung to make it and the rotating body 44 swing counterclockwise around the swing shaft 3 to unfold the car; then, release the vertical rod 45 and continue to unfold the car , at this time, the bayonet 51 slides along the arc surface 13 of the coupling piece 1 toward the unfolding slot 11; when the bayonet 51 slides into the unfolding bayonet 11, under the action of the return spring 52, the vertical rod 45 rotates along the After the vertical sliding hole 441 of the body 44 slides inward for a short distance, the unfolding process of the vehicle is completed.

It can be seen from the above that the structure of the folding structure 5 is relatively simple, the required parts and components are less, and the operation is relatively easy, but in order to avoid misoperation, in the present invention, an anti-misoperation structure 6 is also provided, which includes Anti-misoperation button 61, button return spring 62 and button seat 63, wherein:

The button seat 63 is installed into the lower end of the vertical rod 45, and a button seat hole 631, a button seat linking circular hole 632 and a swinging hole 632 for the detent 51 and the swing shaft 3 to pass through are provided therein. The second avoidance strip hole 633 of the shaft; the anti-misoperation button 61 includes a button main body 611, exposed pressing parts 612 and locking parts 613 at both ends of the button main body 611; The exposed sliding hole 452 and the outer locking hole 453 exposed by the exposed pressing part 612 and the locking part 613 are respectively located outside and inside the rotating body 44; The locking port 443 into which the locking portion 613 falls; after the anti-misoperation button 61 and the button return spring 62 are arranged in the button placement hole 631, under the action of the button return spring 62, the exposed pressing portion 612 is released from the The exposed sliding hole 452 is exposed, and the locking portion 613 is exposed from the outer locking hole 453 and then snapped into the locking opening 443 of the rotating body 44 . The swing shaft 3 passes through the shaft hole of one of the coupling plates, and traverses the shaft hole 444 of the rotating body 44 , the first avoidance strip hole 454 of the swing shaft of the vertical rod 45 and the second avoidance of the swing shaft of the button seat 63 in sequence. The bar hole 633 is then passed through the shaft hole of the other coupling piece, and finally riveted or tightened with screws. When the vertical rod is pulled, with the help of the first and second avoidance bar holes, the swing shaft will not hinder the vertical rod. Sliding in the vertical sliding hole 441 of the rotating body. When the car is to be folded or unfolded, the exposed pressing portion 612 of the anti-misoperation button 61 must be pressed first, so that the button will slide into the button seat 63 after overcoming the force of the button return spring 62. When the locking portion 613 slides away from the rotating body When the locking port 443 of 44 is locked, the vertical bar can be pulled to fold or unfold the car.

As can be seen from the above, only by first operating the anti-misoperation button 61 of the anti-misoperation structure 6, so that after unlocking the rotating body 44, the vertical rod 45 can be pulled to fold or unfold the vehicle, so that there will be no Accidentally pulled the vertical rod and folded the car; at the same time, because the structures of the folding structure 5 and the anti-misoperation structure 6 are relatively simple, and the anti-misoperation button of the anti-misoperation structure 6 is pressed by Sliding into the button seat to release the locking of the vertical rod pulling out is relatively labor-saving during operation, so the structure of the utility model is simpler and more reasonable, the production cost is lower, and the use is safer and the operation is more labor-saving.

It has always been a common practice to connect a return spring between the swing shaft and the bayonet, and the return spring is usually a tension spring. In this embodiment, in order to avoid the interference between the return spring and the components of the anti-misoperation structure, as shown in FIGS. After the installation hole 634 is installed, the upper end rests on the swing shaft 3, and the lower end is supported by the support block 64 installed on the bottom surface of the button seat 63, which not only facilitates the installation of the return spring, but also prevents the user from pulling the vertical rod. Excessive force may cause damage to the return spring.

In this embodiment, as shown in Figures 3 to 5, the button return spring is a compression spring, and there are two, so that the sliding of the button can be relatively stable.

Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that, without departing from the principles and spirit of the present invention as defined in the appended claims, the The utility model makes various changes or modifications. Therefore, the detailed description of the embodiments of the present disclosure is only used to explain, not to limit the present invention, but the scope of protection is defined by the content of the claims.
