[0015] refer to Figure 1 , Figure 2 and Figure 3 As shown, the device includes a seat body 1 and a side-sliding mechanism for slidably mounting the seat body 1 onto a disc steel frame 2. The side-sliding mechanism includes a main body sliding steel frame 3, which is fixed to the seat body 1 and moves with the seat body 1; a side-sliding locking block 4, which is movably mounted on the main body sliding steel frame 3 and can engage or disengage from a limiting hole 5 on the disc steel frame 2; and a steel wire rope 6, one end of which is connected to the side-sliding locking block 4 and the other end of which is connected to a side-sliding adjusting handle 7. Pulling the side-sliding adjusting handle 7 drives the side-sliding lock via the steel wire rope 6. The fixed block 4 moves upward, causing the side-sliding locking block 4 to disengage from the limiting hole 5, allowing the seat body 1 to slide and unlock relative to the disc steel frame 2. Pulling the side-sliding adjustment handle 7 pulls the side-sliding locking block 4 upward through the steel wire rope 6. After unlocking, the seat body 1 can slide a certain distance. After releasing the handle, the side-sliding locking block 4 resets and locks under the action of the side-sliding locking torsion spring 12. The seat body 1 will stay in a certain position. Unlocking, sliding, and locking can be completed with one hand, so parents do not need to take their hands off their children, greatly improving the convenience and safety of use.

[0016] refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the seat body 1 is connected to the body sliding steel frame 3 via a body sliding block 8. After the side sliding locking block 4 is unlocked, the body sliding block 8 slides horizontally out or retracts along the guide groove 9 on the disc steel frame 2. The guide groove 9 can be directly stamped and formed on the disc steel frame 2. The side sliding locking block 4 is provided with a swing arm 10. The steel wire rope 6 is fixed to the swing arm 10 by a pin. When pulled, a torque is generated to make the swing arm 10 swing upward to complete the unlocking. The swing arm 10 is hidden in the cavity of the body sliding steel frame 3. After the side sliding locking block 4 is reset, the side sliding locking block 4 abuts against the outer edge of the disc steel frame 2 to achieve the limit. The side-sliding locking block 4 has an insert shaft 11 extending towards the sliding steel frame 3. A side-sliding locking torsion spring 12 is fitted onto the insert shaft 11. One end of the side-sliding locking torsion spring 12 abuts against the sliding steel frame 3, and the other end abuts against the side-sliding locking block 4. This is used to drive the side-sliding locking block 4 to automatically return to its original position and re-lock after the side-sliding adjustment handle 7 is released. One end of the side-sliding locking torsion spring 12 abuts against the steel frame, and the other end abuts against the locking block for automatic return and locking. A flexible sheath can be fitted over the wire rope 6. The two ends of the sheath are respectively positioned on the sliding steel frame 3 and the seat body 1 to maintain the bending path of the wire rope 6 and protect against friction. The side-sliding adjustment handle 7 is connected to the seat body 1 through a first tension spring and automatically resets after the side-sliding adjustment handle 7 is released. The seat body 1 is also provided with a body gear adjustment mechanism, which includes: a body gear shaft 13, which is movably inserted through the seat body 1 and selectively engages with a gear hole 14 on the body sliding steel frame 3; a body gear adjustment handle 15, which is installed on the seat body 1 via a second tension spring and is linked to the body gear shaft 13; and a body sliding shaft 16, which is inserted into the body sliding steel frame 3 and whose two ends extend into the slide rails 17 opened inside the seat body 1. The body gear shaft 13 and the body sliding shaft 16 are arranged in parallel to form a composite guide for the angle adjustment and lateral sliding movement of the seat body 1. When the body gear adjustment handle 15 is pulled, the body gear shaft 13 disengages from the gear hole 14, allowing the seat body 1 to be adjusted between an upright and tilted angle relative to the body sliding steel frame 3. After releasing the handle, the body gear shaft 13 resets under the action of the second tension spring and re-inserts into the corresponding gear hole 14, thereby locking the angle. The seat body 1 can be adjusted to slide sideways at any angle, whether upright or tilted. The angle adjustment mechanism and the side-sliding mechanism share the same sliding steel frame 3 as the mounting base. The disc steel frame 2 can be mounted on the disc 18.

[0017] Fix the main body sliding block 8 and the main body sliding steel frame 3 with screws. Then, insert one end of the steel wire rope 6 into the side sliding locking block 4 and press in the side sliding locking torsion spring 12. Use screws to install the installed side sliding locking block 4 onto the main body sliding steel frame 3. Install the main body gear adjustment handle 15 and the side sliding adjustment handle 7 into the seat body 1 respectively. The main body gear adjustment handle 15 and the side sliding adjustment handle 7 are reset on the seat body 1 by the first tension spring and the second tension spring (not shown) respectively. After installation, place it on the main body sliding steel frame 3-9. Insert the other end of the steel wire rope 6 into the side sliding adjustment handle 7. Pass the main body sliding shaft 16 and the main body gear shaft 13 through the seat body 1 and the main body sliding steel frame 3 to complete the assembly. Finally, assemble the seat body 1 onto the disc to complete the assembly.

[0018] In use, first pull the main body gear adjustment handle 15 to disengage the main body gear shaft 13 from the gear position on the main body sliding steel frame 3. After adjusting to a suitable angle, release the main body gear adjustment handle 15; this allows for upright / tilted angle adjustment of the main body. Pull the side-sliding adjustment handle 7, which, through the steel cable 6, moves the side-sliding locking block 4 upward. After unlocking, the main body assembly can slide out a certain distance. After releasing the handle, the side-sliding locking block 4 resets and locks under the action of the side-sliding locking torsion spring 12, and the seat body 1 will remain in a certain position. Note: The seat body 1 can slide out at any angle (upright / tilted).
