Furthermore, in the above technical solution, the positioning block is composed of a main body of the positioning block and a protrusion integrally formed with the lower end thereof, wherein a through hole and a long opening are respectively provided on the surface and the upper end of the main body of the positioning block.

Furthermore, in the above technical solution, the joint seat is integrally formed by four panels with positioning holes, one of which is fixedly mounted with a bent connecting block with screw holes; the lower joint is inlaid In the joint seat, it is fixed and installed by screws.

Further, in the above technical solution, the upper joint includes a joint main body, an opening is opened at the lower end, and a long through hole and a positioning hole are opened on the surface, wherein the width of the opening is consistent with the width of the joint seat, and the depth is the same as that of the lower joint. The radius of the curved surface of the joint is consistent; a positioning pin is inserted into the positioning hole and fixed with the upper joint.

Furthermore, in the above technical solution, the bottom plate is fixedly installed with the joint seat through a baffle plate and screws.

Further, in the above technical solution, the positioning block is set in the upper joint, and a spring is installed between the two, one end of which is connected to the positioning pin, and the other end is pushed against the bottom of the positioning block, wherein the positioning pin is embedded In the long opening in the positioning block, it can move up and down in the long opening.

Compared with the prior art, the utility model scooter folding device has the following beneficial effects:

1. The operation is simple. The scooter folding device of the utility model can realize the folding of the scooter by adjusting the fixed block in the through hole.

2. Good stability. In the scooter folding device of the utility model, a spring is installed between the upper joint and the fixed block integrally formed with the card protrusion. When unfolded, the card protrusion coincides with a card groove. When folded, the card protrusion and The other draw-in groove coincides with each other, and the spring will generate tension in both cases so that the draw-in protrusion and the draw-in groove are closely connected, which greatly improves the stability of the folding device.

3. High safety. The scooter folding device of the utility model moves the fixed block through the through hole so that the card protrusion reaches two slots at different positions to realize the folding of the scooter. Basically, it will not collide with external objects and cause the scooter The connection between the body and the base plate is not fixed, thereby avoiding some avoidable accidents.

Detailed ways:

Below in conjunction with specific embodiment and accompanying drawing, the utility model is further described.

As shown in Figures 1 and 2, the scooter folding device includes a bottom plate 1, a folding device 2 and an upper joint 3, and the folding device 2 consists of a lower joint 22 with a card slot 221 on an arc surface and a card slot 221 with it. The matching positioning block 23 of the locking protrusion 233 and the joint seat 21 are formed by cooperating with a spring 4 .

The joint seat 21 is formed by integrally fixing and forming four panels provided with positioning holes, and a connecting block 7 is fixedly installed on one of the panels, and the connecting block 7 is bent to form an upper panel and a lower panel. The height is equal, and the upper panel is provided with a screw hole, and a screw passes through the screw hole to make the upper joint 3 and the joint seat 21 fixedly connected. The lower joint 22 is inlaid in the joint seat 21, fixed and installed by the screw 5, and the arc surface of the lower joint 22 is provided with two slots 221, one of which cooperates with the protrusion 233 of the positioning block 23 to support and fix, and the other cooperates with the The locking protrusion 233 of the positioning block 23 plays a folding role.

The positioning block 23 is composed of a positioning block main body 231 and a protrusion 233 fixed integrally with the lower end thereof, wherein a through hole 232 and a long opening 234 are defined on the surface and the upper end of the positioning block main body 231 respectively. An opening 33 is provided at the lower end of the upper joint 3, and a long through hole 32 and a positioning hole are provided on the surface of the joint body 31, wherein the width of the opening 33 is consistent with the width of the joint seat 21, and the depth is consistent with the arc radius of the lower joint 22. The positioning tip 6 is fixed with the upper joint 3 after being inserted into the positioning hole. The bottom plate 1 is provided with screw holes, through which the screws 5 cooperate with a baffle plate 12 and the joint seat 21 for fixed installation.

The lower joint 22 is embedded in the joint seat 21, fixed and installed by screws 5, the positioning block 23 is set in the upper joint 3, and a spring 4 is installed between them, one end of the spring 4 is connected with the positioning pin 6, and the other end is against the The bottom of the positioning block 23 , wherein the positioning pin 6 is embedded in the long opening 234 of the positioning block 23 , can move up and down in the long opening 234 . The card protrusion 233 at the lower end of the positioning block 23 coincides with the card slot 221 provided on the arc surface of the lower joint 22, and the opening 33 provided by the upper joint 3 snaps into the joint seat 21, wherein the screw holes provided by the two are aligned. The upper joint 3 is connected with the joint seat 21.
