Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0025] For easy adjustment of the basket's reclining angle, please refer to... Figure 1 , Figure 2 and Figure 3As shown, the device includes a carrier backrest 1 and a backrest cover 13, which are rotatably connected by a backrest connecting pin 5. A backrest adjustment handle 2 is fixed to the backrest cover 13. An angle adjustment pull rope assembly 4 has its fixed end fixed to the backrest adjustment handle 2, and its wire end connected to the backrest adjustment handle 11 and extending into the inside of the carrier backrest 1. A backrest adjustment slider 7 is connected to the fixed end of the angle adjustment pull rope assembly 4 and is connected to a movable backrest adjustment pin 9. A backrest stop spring 8 has its two ends connected to the carrier backrest 1 and the backrest adjustment slider 7, respectively. By connecting the backrest adjustment handle 11 and the backrest adjustment slider 7 in series through the angle adjustment pull rope assembly 4, remote control can be achieved. This solves the problems of large space occupation and inconvenient operation of traditional infant carrier backrest adjustment mechanisms. Users only need to perform two consecutive actions of pulling the handle and pressing down the backrest to complete the angle switching, which is more efficient than the traditional multi-step adjustment method. The overall structure is simple.

[0026] To facilitate assembly with adjustable reclining angle, please refer to... Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the backrest adjustment handle 7 is connected to the backrest adjustment handle base 2 via a guide hook spring 12. The backrest adjustment slider 7 is provided with a guide rail. The backrest adjustment pin 9 is slidably engaged with the guide rail via a positioning pin 6. The guide rail is an arc-shaped groove, allowing the backrest adjustment pin 9 to move along a predetermined trajectory to disengage from or engage with the position hole of the basket backrest 1. The fixed end of the angle adjustment pull rope assembly 4 is fixed to the backrest adjustment handle base 2 with a self-tapping screw, and the wire end is fixed to the backrest adjustment slider 7 with a self-tapping screw. The backrest connecting pin 5 passes through the basket body 10 and the backrest back cover 13 in sequence, forming a rotation fulcrum. The basket backrest 1 is provided with at least three equidistant position holes, which cooperate with the backrest adjustment pin 9 to achieve three-position angle adjustment. First, fix the fixed end of the angle adjustment pull rope assembly 4 to the backrest adjustment handle seat 2 with self-tapping screws 3. Lock the wire end of the angle adjustment pull rope assembly 4 into the hole of the backrest adjustment handle 11. Then, connect the two ends of the guide hook spring 12 to the backrest adjustment handle seat 2 and the backrest adjustment handle 11 respectively. Then, assemble it to the backrest back cover 13 with self-tapping screws 3. Next, the backrest connecting pin 5 is inserted into the basket body 10 and the backrest back cover 13 in sequence. The angle adjustment pull rope assembly 4 passes out from the basket body 10 and the backrest back cover 13. Fix the fixed end and the wire end of the angle adjustment pull rope assembly 4 to the basket backrest 1 and the backrest adjustment slider 7 respectively with self-tapping screws 3. After the backrest adjustment pin 9 is inserted from the side of the basket backrest 1, connect the backrest adjustment slider 7 and the backrest adjustment pin 9 with the positioning pin 6. Then, connect the two ends of the backrest stop spring 8 to the basket backrest 1 and the backrest adjustment slider 7 respectively. Finally, assemble the basket backrest 1 to the backrest back cover 13 with self-tapping screws 3. When finger force is applied to the backrest adjustment handle 11, the backrest adjustment handle 11 pulls the angle adjustment rope assembly 4 upward. Simultaneously, the other end of the angle adjustment rope assembly 4 drives the backrest adjustment slider 7 forward. The backrest adjustment pin 9 moves along the track of the backrest adjustment slider 7 under the action of the positioning pin 6. When the positioning pin 6 reaches the bottom of the backrest adjustment slider 7, the backrest adjustment pin 9 completely disengages from the stop hole of the basket backrest 1. While pulling the backrest adjustment handle 11, a vertical downward palm force is applied to the position of the basket backrest 1 near the backrest adjustment handle 11. The basket backrest 1, along with the backrest cover 13, rotates along the backrest connecting pin 5. Figure 4 As shown, after the two forces are finally released, the backrest adjustment handle seat 2 and the backrest adjustment pin 9 are reset by the tension of the guide hook spring 12, the wire end of the angle adjustment pull rope assembly 4 and the backrest position spring 8. Then the backrest adjustment pin 9 is locked into the position hole, which can realize the switching of the three-position basket reclining angle.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
