Detailed ways

The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

It can be seen from the structural diagrams of accompanying drawings 1 to 4 that this embodiment provides a child car safety seat, which includes a base 3, a seat 1 slidably mounted on the base 3, an adjustment base 3 and a seat. An angle adjustment mechanism for the relative position between the chairs 1, and a locking mechanism for limiting the relative position between the base 3 and the seat 1.

The angle adjustment mechanism includes a connecting frame 8 whose end is rotatably connected to the seat 1 and the other end is rotatably connected to the base 3. The rotating joints at both ends of the connecting frame 8 are respectively the first fulcrum and the second fulcrum. The angle adjusting mechanism also includes The third fulcrum connecting the base 3 and the seat 1, the third fulcrum is fixedly arranged on one of the base 3 and the seat 1 and is slidably connected with the other of the base 3 and the seat 1, when the seat moves relative to the base When at least one of the first fulcrum, the second fulcrum and the third fulcrum moves relative to the base 3, the position of the seat 1 relative to the base 3 is changed. In this embodiment, at least two fulcrums are moved relative to the base 3. The change of the position of the seat 1 relative to the base 3 is realized.

In this embodiment, the base 3 is provided with a first guide groove 4, and the seat 1 is fixedly provided with a first guide pin 2 capable of sliding along the extending direction of the first guide groove 4. The first guide pin 2 and the seat 1 The junction of is the third fulcrum mentioned above. One end of the connecting frame 8 is connected to the seat 1 through the first rotating shaft 7 , and the other end of the connecting frame 8 is connected to the base 3 through the second rotating shaft 10 . The first guide groove 4 is arc-shaped and arranged along the front-rear direction. In this children's car safety seat, the three vertices of the triangle are formed by the first guide pin 2, the first rotating shaft 7, and the second rotating shaft 10, and the inner angle of the triangle is changed by the sliding of the first guide pin 2 in the first guide groove 4 and side length, thereby realizing the angle adjustment between the seat 1 and the base 3.

Connecting frame 8 is positioned at the front portion of children's car safety seat. The first guide slot 4 is arranged at the rear of the base 3 .

Referring to accompanying drawings 1 and 2, the locking mechanism in this embodiment includes at least two locking holes 5 opened on the base 3, which are movably arranged on the seat 1 and are detachably inserted into the locking holes 5. The lock bolt 6, the operating mechanism that can pull the lock bolt 6 to move. The locking bolt 6 moves along its own axial direction, and its moving direction is the left and right direction.

With reference to accompanying drawing 3 and accompanying drawing 4, the operating mechanism in the present embodiment comprises the handle 9 that is movably arranged on the seat 1, the second guide pin 13 that is fixedly arranged on the lock bolt 6, and the handle 9 is provided with a second guide pin.
