Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0018] like Figure 1-11 As shown, the present invention proposes a children's tricycle that is easy to disassemble and assemble. It includes a main body 1, a handlebar assembly 2 at the front end of the main body 1, a pair of easy-to-disassemble and assemble components 3 at the bottom of the handlebar assembly 2, a front wheel body 4 between the two easy-to-disassemble and assemble components 3, and a transmission component 5 on each easy-to-disassemble and assemble component 3. The front end of the support frame 10 of the main body 1 is provided with a shaft cylinder 14, and the rotating shaft 21 of the steer assembly 2 is movably inserted into the shaft cylinder 14, so that the steer body 20 can rotate flexibly relative to the support frame 10; the inverted U-shaped mounting tube 22 at the bottom of the rotating shaft 21 is connected to the easy-to-disassemble assembly 3 through its end tube, forming the connection basis for the front wheel drive. The insert 36 of the easy-to-disassemble component 3 is adapted to be inserted into the end tube of the inverted U-shaped mounting tube 22. The elastic strip 37 on the inner wall of the insert 36 pushes the positioning pin 38 outward. The positioning pin 38 passes through the positioning hole 23 on the end tube of the inverted U-shaped mounting tube 22, realizing the quick engagement of the insert 36 and the inverted U-shaped mounting tube 22. The locking shell 30 at the bottom of the insert 36 serves as the connection carrier between the front wheel body 4 and the transmission component 5. The internal moving groove 32, fixing hole 31 and sliding plate 39 constitute the locking mechanism. The inserts 42 on both sides of the front wheel body 4 are inserted into the fixing holes 31 of the locking housing 30, and the initial positioning is achieved through the gap fit between the fixing holes 31 and the inserts 42; the baffle 40 inside the front wheel body 4 divides the internal space into two semi-circular inserts 41, which are used to precisely fit with the docking rod 53 of the transmission component 5 to ensure the stability of power transmission. The transmission assembly 5 includes a transmission rod 50. One end of the transmission rod 50 is inserted into the fixing hole 31 of the locking housing 30, and the mating rod 53 at its top end is fitted and inserted into the semi-circular insertion hole 41 of the front wheel body 4 to achieve circumferential fixation of the transmission rod 50 and the front wheel body 4. The annular groove 51 on the transmission rod 50 is engaged with the fixing groove 312 (inverted V-shaped end) of the slider 39. Under the elastic force of the spring 311, the slider 39 always presses the fixing groove 312 into the annular groove 51 to prevent the transmission rod 50 from axially dislodging. The pedal 52 at the other end of the transmission rod 50 can rotate flexibly through a movable connection structure (such as a bearing) to ensure smooth pedaling transmission. Light strips 6 are symmetrically arranged on both sides of the support frame 10.

[0019] During installation: 1. Pre-connection of front wheel body 4 and easy-to-disassemble component 3: Align the locking shells 30 of the two easy-to-disassemble components 3 with the inserts 42 on both sides of the front wheel body 4, so that the inserts 42 are inserted into the fixing holes 31 of the locking shells 30, and the initial combination of the front wheel body 4 and the easy-to-disassemble component 3 is completed. 2. Easy assembly and disassembly of component 3 and handlebar assembly 2: Press the positioning pin 38 to compress the elastic strip 37 and retract it into the insert 36. At the same time, insert the insert 36 into the end tube of the inverted U-shaped mounting tube 22. When the insert 36 is fully inserted, the positioning pin 38 pops out from the positioning hole 23 under the restoring force of the elastic strip 37, realizing the automatic locking of the two and completing the connection between the front wheel and the handlebar. 3. Installation and locking of transmission component 5: Manually press the bottom of the slide plate 39 to make it slide upward in the moving groove 32. At this time, the protrusion 310 compresses the spring 311, and the inverted V-shaped end of the fixing groove 312 retracts into the moving groove 32, releasing the obstruction of the fixing hole 31. Then, insert the transmission rod 50 into the fixing hole 31 until the docking rod 53 at its top abuts against the baffle 40 of the front wheel body 4. Rotate the transmission rod 50 to align the docking rod 53 with the semi-circular insertion hole 41 and insert it to achieve circumferential positioning of the transmission rod 50 and the front wheel body 4. During the continuous insertion of the transmission rod 50, when the annular groove 51 of the rod body moves to the position of the slide plate 39, release the slide plate 39. The spring 311 resets and pushes the slide plate 39 downward. The inverted V-shaped end of the fixing groove 312 is engaged in the annular groove 51, thereby locking the transmission rod 50 axially and preventing it from coming out of the locking housing 30.
