The mechanism can fold the rear wheel part of the children's scooter, so that the volume of the package is reduced, and meanwhile, the seat is lifted while the rear wheel is folded, so that the mechanism can cope with the change of the leg length caused by the increase of the age of the children, and is suitable for children in higher ages.
And shaft cover plates are respectively arranged on two sides of a hinge seat at the hinge fixing position of the rear fork supporting and fixing bracket and the rear fork. The structure plays a role in decoration and safety improvement.
One end of the rear fork supporting and fixing bracket is sleeved and fixed in a pipe fitting hole of the frame through a special-shaped sleeve head. The special-shaped sleeve head of the rear fork supporting and fixing bracket is rectangular, square or prismatic and is sleeved with the pipe fitting hole of the frame with the corresponding shape.
The folding mechanism has the advantages of reasonable structural design, convenient production, assembly, operation and adjustment, good stability, low packaging and transportation cost, and is especially applied to the rear wheel folding mechanism of the children scooter, and the folding mechanism is mainly used as the folding mechanism of the rear wheel of the children scooter and the structural improvement of similar products.

Description of the embodiments
The construction and use of the present utility model will now be further described with reference to the accompanying drawings. As shown in fig. 1-4, one end of a rear wheel component of the mechanism is provided with a row wheel 301, the other end of the rear wheel component is hinged and fixed with a hinging seat 101 at one end of a rear fork supporting and fixing bracket 1, and the other end of the rear fork supporting and fixing bracket is sleeved and fixed on a frame. The rear wheel assembly is a rear fork 3 which is symmetrically arranged on two sides and connected into a whole, one end of the rear fork is hinged and fixed on a hinged seat 101 at one end of a rear fork supporting and fixing bracket through a rear wheel pair locking screw 5, and the outer sides of the other ends of the rear fork are respectively provided with a row wheel 301.
The rear fork is characterized in that a supporting iron piece 7 is arranged at the hinged fixing position of the rear fork and the rear fork supporting and fixing bracket, one end of the supporting iron piece is fixed to the rear fork on one side, the other end of the supporting iron piece is inserted into a rear wheel pair locking screw, an adjusting hole 701 is formed in one disc surface side of the supporting iron piece, an arc hole on one side of the adjusting hole is communicated with a limit hole on the other side which is equidistantly formed, one end of a rotating shaft 6 in a hinging seat of one end of the rear fork supporting and fixing bracket at the hinged fixing position of the rear fork and the rear fork supporting and fixing bracket penetrates through the adjusting hole of the supporting iron piece, the other end of the rotating shaft is inserted into one end of a rear wheel release button 2 at the hinging seat in the rear fork supporting and fixing bracket, the other end of the rear wheel release button extends out of a sliding hole 102 at the hinging seat of the rear fork supporting and fixing bracket, a spring is arranged at the bottom of the rear wheel release button in the hinging seat of the rear fork supporting and fixing bracket, the sliding hole of the rear fork supporting and the adjusting hole of the supporting and fixing bracket is aligned with one end of the arc hole, the rear wheel release button is pressed to drive the rotating shaft to slide in the arc hole on one side of the adjusting hole, and the rear wheel release button is driven to release the rotating shaft to limit the rotating shaft. The two sides of the hinging seat at the hinging and fixing position of the rear fork supporting and fixing bracket and the rear fork are respectively provided with a shaft cover plate 4. One end of the rear fork supporting and fixing bracket is sleeved and fixed in a pipe fitting hole of the frame through a special-shaped sleeve head, and the special-shaped sleeve head is rectangular.
After a rear wheel pair lock screw of the mechanism fixes a rear fork, a supporting iron piece, a rear fork supporting fixing bracket, a rotating shaft and a rear wheel release button together, the rotating shaft is fixed with the rear wheel release button together, the rear wheel release button resets the rotating shaft and the button to a locking position through a spring to realize limit, the rotating shaft is pushed into a semicircular groove position (an arc hole) of the supporting iron piece after the button is pressed down, the rotating shaft enters a salient point groove position (a limit hole) of the supporting iron piece, and the spring ejects the rotating shaft into a salient point to realize limit. Therefore, the rotating shaft penetrates through the rear wheel release button to realize the limit of the rear wheel release button, and meanwhile, the rotating shaft is pushed into the semicircular groove of the supporting iron piece to realize the rotation of the rear fork after the rear wheel release button is pressed down, namely, the angle and the height of the rear fork are adjusted by pressing the rear wheel release button, and the angle and the height after the adjustment are locked after the rear wheel release button is released.
According to the structural characteristics, the travelling wheel can also be arranged in an open groove between the other ends of the rear forks, and the central hole of the travelling wheel is fixedly connected with the rear forks on two sides through the travelling wheel shafts.
In summary, the mechanism effectively reduces the packaging volume and the transportation cost in the packaging process, and in the using process, the seat is lifted while the rear wheel is folded, so that the product can be suitable for children with more age groups.
