DETAILED DESCRIPTION

[0038] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments; in the following description, specific details such as specific configurations and components are provided only to help fully understand the embodiments of the present invention. Therefore, it should be clear to those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present invention. In addition, for the sake of clarity and brevity, the description of known functions and structures is omitted.

[0039] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features thereof may be combined with each other.

[0040] like Figure 1-9 The present embodiment shows a novel tricycle for children, comprising: a frame 100 and a body 200; the body 200 is movably mounted on the frame 100; a rear wheel rod 210 is foldably mounted on the body 200; a rear wheel 230 is foldably mounted on the rear wheel rod 210 through a double-press locking device 220; the rear wheel rod 210 comprises an upper shell 211 and a lower shell 214, and the upper shell 211 and the lower shell 214 are fixedly mounted between them; an upper pressing groove 212 and a lower pressing groove 215 are respectively formed at the ends of the upper shell 211 and the lower shell 214; the double-press locking device 220 comprises a first button 221 mounted in the upper pressing groove 212, a second button 222 mounted in the lower pressing groove 215, a folding body 240 mounted between the upper shell 211 and the lower shell 214, and a first limit block 223, a second limit block 224, a first spring, and a second spring mounted on the folding body 240.

[0041] When the children's tricycle is transformed into a children's balance car, it is necessary to first unlock the rear wheel rod 210, then unlock the double-press locking device 220, fold the two rear wheels 230 to a certain angle, and then fold the rear wheel rod 210 until the two rear wheels 230 are placed side by side to transform into a children's balance car.

[0042] Furthermore, the ends of the upper shell 211 and the lower shell 214 are respectively provided with a first upper limit groove 213 and a first lower limit groove 216, and the two ends of the folding body 240 are respectively provided with a second upper limit groove 241 and a second lower limit groove 242; a first limit block 223 is placed between the first upper limit groove 213 and the second upper limit groove 241, a first spring is placed between the bottom wall of the second upper limit groove 241 and the first limit block 223, and an end of the first button 221 is against the first limit block 223; a second limit block 224 is placed between the first lower limit groove 216 and the second lower limit groove 242, a second spring is placed between the bottom wall of the second lower limit groove 242 and the second limit block 224, and an end of the second button 222 is against the second limit block 224.

[0043] Specifically, when the rear wheel 230 needs to be folded, the first button 221 and the second button 222 are pressed at the same time. The first button 221 presses the first limit block 223 completely into the second upper limit groove 241, and the second button 222 presses the second limit block 224 completely into the second lower limit groove 242. At this time, the double-press locking device 220 can be unlocked and the rear wheel 230 can be folded. The first button 221 and the second button 222 need to be pressed at the same time to unlock, thereby avoiding the possibility of accidentally touching the unlock button, which may cause the children's tricycle to roll over.

[0044] Furthermore, a limiting device 250 is installed in the vehicle body 200, and a plurality of limiting holes 110 cooperating with the limiting device 250 are provided on the vehicle frame 100. The limiting device 250 includes a lifting column 251, a push button 252 and a third spring.

[0045] Furthermore, the vehicle body 200 includes a first shell 260 and a second shell 270 , and the first shell 260 and the second shell 270 are fixedly connected.

[0046] Furthermore, a lifting groove 280 is opened in the first shell 260 and the second shell 270, and a lifting column 251 is placed in the lifting groove 280 so as to be liftable. The lifting groove 280 is connected to a push button groove 290, and a push button 252 is placed in the push button groove 290 to limit the position. The push button 252 and the lifting column 251 are respectively provided with a first slope 2521 and a second slope 2511, and the surface of the first slope 2521 and the surface of the second slope 2511 are offset against each other.

[0047] Furthermore, the fifth spring is placed in the lifting slot 280 , with one end of the fifth spring abutting against the bottom wall of the lifting slot 280 and the other end abutting against the end of the lifting pin 251 .

[0048] Specifically, the body 200 of this children's tricycle is movable. When the position of the body 200 on the frame 100 needs to be adjusted, the push button 252 is pressed inward, and the first slope 2521 on the push button 252 presses up the second slope 2511, and then presses down the lifting column 251. After it is pressed down, the lifting column 251 is no longer inserted into the limit hole 110, and is unlocked. At this time, the body 200 can be moved. After moving to the appropriate position, release the push button 252. Under the action of the spring, the lifting column 251 is again inserted into the limit hole 110 to be fixed.

[0049] Furthermore, a handlebar 120 , a front wheel 130 , pedals 140 and a push handle 150 are also mounted on the frame 100 .

[0050] Furthermore, a seat 300 is installed on the vehicle body 200 .

[0051] Furthermore, a rear wheel 230 is installed on one side of the folding body 240 .
