In conjunction with the accompanying drawings, the working principle of clamping and locking the seat belt 40 by the seat belt locking mechanism 10 of the present invention is described in detail:

The infant carrier 100 of the present invention is installed on the car seat 200. In the open state, the operating member 16 is in the position shown in FIG. 1 or FIG. In the open state shown in Figure 1 or Figure 8 to form an opening 131, the opening 131 for the safety belt 40 to enter the safety belt channel 18 and to pass in the clamping area 13; 16 rotates in the direction indicated by the arrow, the rotating operating part 16 drives the driving locking part 12 to rotate synchronously through the pivot shaft 15, and the synchronously rotating driving locking part 12 drives the pushing part 121 on the pushed part 111 of the sliding clamping part 11 Slide up and push the pushed part 111, so that the second clamping part 114 of the sliding clamping part 11 is gradually approached to the first clamping part 141a, thereby slidingly adjusting the clamping area 13 so that the clamping area 13 gradually shrinks and closes .

When the operating member 16 is rotated to the locking position (as shown in Figure 3, Figure 4 or Figure 10), the first positioning structure 112 and the second positioning structure 122 at this time are mutually engaged and positioned to realize the driving of the locking member 12. The locking of the sliding clamping member 11 limits the excessive rotation of the operating member 16 under the resistance of the stopper 113, so that the clamping area 13 is in the closed state shown in Figure 3, Figure 4 or Figure 10; and at this time The first clamping part 141a and the second clamping part 114 are all in contact with the two opposite sides of the safety belt 40, so that the safety belt 40 is tensioned and clamped and locked, and then the convex rib on the second clamping part 114 Under the action of 114a, the seat belt 40 is locked more securely and reliably due to greater frictional force, thereby completing the locking operation of the seat belt 40 by the seat belt locking mechanism 10 of the present invention, thus making the present invention The infant carrier 100 can be installed on the car seat 200 more conveniently and quickly, as shown in FIG. 3 .

When the infant carrier 100 of the present invention needs to be disassembled from the car seat 200, the operating member 16 is rotated in the direction indicated by the arrow near the operating member 16 in FIG. 3 or FIG. 3 or the position shown in FIG. 4 is rotated to the position shown in FIG. 1, that is, the rotating drive lock 12 makes the second positioning mechanism 122 break away from the positioning lock with the first positioning structure 112, and the elastic restoring force provided by the elastic element 19 Under the action, the second clamping part 114 of the sliding clamping part 11 is automatically reset along the position away from the first clamping part 141a, so that the second clamping part 114 and the first clamping part 141a are separated from each other, so that the second clamping The tightening portion 114 and the first clamping portion 141a break away from the two opposite sides of the safety belt 40 at the same time, so that the clamping area 13 is in the open state shown in FIG. 1 or FIG. Leave the seat belt channel 18; at this moment, the seat belt 40 can be taken out from the seat belt locking mechanism 10 of the present invention, thereby completing the operation process of dismounting the infant carrier 100 of the present invention from the car seat 200.

Compared with the prior art, since the sliding clamping part 11 of the seat belt locking mechanism 10 of the present invention is slidably arranged on the infant carrier 100 and forms a clamping area 13 between the infant carrier 100 , the driving locking part 12 is pivotally connected to the infant carrier 100 and is in sliding contact with the sliding clamping part 11, the driving locking part 12 slides on the sliding clamping part 11 and pushes the sliding clamping part 11 on the infant carrier 100 Therefore, when the safety belt 40 is placed in the clamping area 13, the rotating drive locking member 12 makes the driving locking member 12 push the sliding clamping member 11 to slide in the direction of reducing the clamping area 13, so that the clamping area 13 The seat belt 40 is clamped between the infant carrier 100 and the sliding clamping member 11, so that the seat belt locking mechanism 10 of the present invention is very convenient for clamping and locking the seat belt 40, and is convenient for the seat belt 40 Assembling and disassembling can also simplify the structure of the safety belt locking mechanism 10 of the present invention. Since the infant carrier 100 of the present invention has the safety belt locking mechanism 10 of the present invention, the infant carrier 100 of the present invention not only has the advantage of simple structure, but also enables the safety belt 40 to be locked when installed on the car seat 200. The assembly and disassembly operation is simple and convenient.

Of course, the above descriptions are only preferred embodiments of the present invention, and cannot limit the scope of rights of the present invention with this, and utilize any two or several embodiments to combine to implement this patent, or make according to the patent scope of the present invention application. Equivalent changes still belong to the scope covered by the present invention.
