[0025] Example

[0026] See also Figure 1-5 , the technical solution provided by this embodiment is as follows:

[0027] A children's tricycle with good comfort comprises a frame 1, a mounting plate 2 is fixedly installed on the top of the frame 1 by bolts, an adjusting mechanism 3 is arranged at the bottom of the mounting plate 2, the adjusting mechanism 3 comprises a mounting column 301 fixedly installed at the bottom of the mounting plate 2, fixing holes 302 are provided on both sides of the mounting column 301, and the fixing holes 302 penetrate into the inner cavity of the mounting column 301, a worm rod 303 is movably installed inside the fixing hole 302, a rocker 304 is fixedly connected to one end of the worm rod 303, a gear 305 is meshedly connected to one side of the worm rod 303, a rotating shaft 306 is fixedly connected to the inner side of the gear 305, a screw rod 307 is arranged on the top of the rotating shaft 306, a lifting block 308 is threadedly connected to the outer side of the screw rod 307, and a seat 4 is fixedly connected to the top of the lifting block 308.

[0028] In a specific embodiment of the utility model, the frame 1 is the main structure of the vehicle, and the function of the mounting plate 2 is to provide a stable platform for installing and supporting other components. The user adjusts the height of the seat 4 by shaking the rocker 304 to adapt to riders of different heights. The fixing hole 302 is used to install the worm rod 303 and allow the worm rod 303 to rotate in the fixing hole 302. The rocker 304 is connected to the gear 305 through the worm rod 303. Shaking the rocker 304 can drive the worm rod 303 to rotate, and the gear 305 is engaged with the worm rod 303. When the worm rod 303 rotates, the gear 305 also rotates, and the shaft 306 rotates with the gear 305. When the shaft 306 rotates, the screw 307 drives the lifting block 308 to move up and down along the mounting column 301, thereby adjusting the height of the seat 4.

[0029] See also Figure 1-4 A through hole 5 is provided at the top of the mounting plate 2, and the lifting block 308 passes through the through hole 5 on both sides of the mounting plate 2. A bearing seat 6 is fixedly installed in the middle part of the bottom of the inner cavity of the mounting column 301, and the bottom end of the rotating shaft 306 is movably installed on the inner side of the bearing seat 6. A baffle 7 is fixedly installed on the outer side of the rotating shaft 306, and the baffle 7 is located between the gear 305 and the screw rod 307. The bottom shape of the lifting block 308 is square and fits the inner wall of the mounting column 301, and its top shape is cylindrical. Telescopic rods 8 are fixedly installed around the bottom of the seat 4, and the bottom of the telescopic rod 8 is sleeved with a pillar 9. The bottom of the pillar 9 is fixedly connected to the mounting plate 2, and a safety belt 10 is provided in the middle part of the seat 4.

[0030] In a specific embodiment of the utility model, the seat 4 is connected to the adjustment mechanism 3 via a lifting block 308, and the height can be adjusted as the lifting block 308 moves up and down. In addition, the telescopic rod 8 and the support 9 at the bottom of the seat 4 can provide additional support and stability, and the safety belt 10 can ensure the safety of the child.

[0031] See also Figure 1 , Figure 2 , Figure 3 and Figure 5 The front end of the frame 1 is movably connected with a head 11, a handlebar 12 is arranged on the top of the head 11, a protective cover 13 is sleeved on the outer side of the handlebar 12, rear wheels 14 are arranged on both sides of the bottom of the rear end of the frame 1, a connecting rod 15 is sleeved on the bottom of the head 11, pin holes 16 are opened on the surfaces of the head 11 and the connecting rod 15, a fixing pin 17 is inserted into the inner side of the pin hole 16, a front wheel 18 is arranged on the inner side of the connecting rod 15, and pedals 19 are arranged on both sides of the front wheel 18.

[0032] In a specific embodiment of the utility model, the front of the vehicle 11 is movably connected to the front wheel 18 by means of a latch, which is convenient for disassembly and carrying. The handlebar 12 is used to control the direction of the vehicle. The protective cover 13 can not only increase the grip but also prevent hand injuries. Through the setting of the pedal 19, children can step on it to drive the vehicle forward.

[0033] Working principle: First, the frame 1 serves as the main structure of the entire vehicle and provides a stable support. The mounting plate 2 is used as a platform for installing accessories, and allows it to be fixed to the frame 1 by bolts. The adjustment mechanism 3 allows the user to adjust the height of the seat 4 according to the height of the rider. The user drives the worm 303 to rotate by shaking the rocker 304. The worm 303 is engaged with the gear 305, so that when the worm 303 rotates, the gear 305 also rotates. The rotation of the gear 305 drives the rotation of the rotating shaft 306 and the screw rod 307. The threaded connection between the screw rod 307 and the lifting block 308 allows the lifting block 308 to move up and down along the screw rod 307. This movement passes through the mounting plate 2 through the through hole 5 and drives the seat 4 to adjust the height up and down. The telescopic rod 8 and the support 9 installed at the bottom of the seat 4 provide additional support and stability for the seat, and the safety belt 10 ensures safety during riding. The front 11 is movably connected to the front wheel 18 through the pin hole 16 and the fixing pin 17, which is easy to disassemble and carry. The handlebar 12 is used to control the direction, and the protective cover 13 increases the grip and prevents hand injuries. Children can step on the pedal 19 to drive the vehicle forward.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
