Aiming at the problems in the background technology, the utility model provides a novel child seat with a back-following function, which has the functions of simple structure, stepless adjustment, safe use and the like.

The technical aim of the utility model is realized by the following technical scheme: the utility model provides a novel child seat of function of following back, includes seat body and back, still includes back support, pneumatic push rod and connecting pipe, the outside at pneumatic push rod is established to the connecting pipe, pneumatic push rod's top pass the connecting pipe and with the one end normal running fit of back support, the other end and the back fixed connection of back support, normal running fit between connecting pipe and the seat body are passed to pneumatic push rod's bottom, the inner wall of connecting pipe is equipped with a plurality of stopper.

Preferably, the backrest support further comprises a connecting piece, wherein the connecting piece is arranged at the top of the pneumatic push rod, and the pneumatic push rod is in running fit with the backrest support through the connecting piece.

Preferably, the connecting piece is provided with a limiting protrusion, and the limiting protrusion can be propped against the inner wall of the limiting block or the connecting pipe.

Preferably, the pneumatic push rod is arranged in the diagonal direction in the connecting pipe, the limiting blocks are of baffle structures and are symmetrically arranged on two sides of the swing direction of the pneumatic push rod, and the size of a gap formed between the baffle plates on two sides is equal to the size of the rotating stroke of the pneumatic push rod.

Preferably, the limiting block and the connecting pipe are of an integrated structure.

Preferably, the pneumatic push rod is connected with a manual switch, and the manual switch is mounted on the seat body.

The utility model has the following beneficial effects: according to the novel child seat with the back-following function, on the premise of realizing the back-following function, the connection mode and the adjustment mode between the backrest and the seat body are optimized, the back-following function of the child seat can be realized by adjusting the pneumatic push rod, stepless adjustment of the backrest is realized on the one hand, the backrest truly plays a role in posture adjustment on the other hand, the production cost of the child seat can be further reduced, the movable range of the backrest can be effectively adjusted, and the use safety of the child seat is further ensured.

In the figure, 1, a seat body; 2. a backrest; 3. a backrest bracket; 4. a pneumatic push rod; 5. a connecting pipe; 6. a limiting block; 7. a connecting piece; 8. a limit protrusion; 9. pull switch.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described in the following in conjunction with the embodiments of the present utility model, and it is obvious that the described embodiments are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

When the novel child seat with the back-tracking function is in specific implementation, when a user sits on the seat body 1, the pull switch 9 can be manually turned on, so that the pneumatic push rod 4 enters a freely movable adjusting state, and at the moment, the lifting force of the pneumatic push rod 4 can ensure that the backrest 2 always has a forward ejection force on the waist and the back of the user, so that the back-tracking function of the backrest 2 is realized; the movable adjustment of the backrest 2 relative to the seat body 1 can be ensured by the running fit between the pneumatic push rod 4 and the backrest bracket 3 as well as between the seat body 1, and the backrest 2 is always clung to the waist and the back of a user in the movable adjustment, so that the backrest 2 can truly play a role in adjusting the posture sitting posture; the design of the connecting pipe 5 can enable the movement between the backrest 2 and the seat body 1 to be more stable, the limiting block 6 in the connecting pipe 5 can effectively limit the movement range of the pneumatic push rod 4, the pneumatic push rod 4 is arranged in the diagonal direction in the connecting pipe 5, the limiting block 6 is of a baffle structure and is symmetrically arranged on two sides of the swing direction of the pneumatic push rod 4, and the size of a gap formed between the baffle plates on the two sides is equal to the size of the rotation stroke of the pneumatic push rod 4; the design makes the clearance that forms between the separation blade of both sides can be a scope that has the swing range, and this swing range is just pneumatic push rod 4 can the wobbling angle, and pneumatic push rod 4 is when being blocked by the separation blade, owing to the separation blade is a plurality of, so makes connecting pipe 5 and pneumatic push rod 4 all remain stable, and the fracture condition of atress inhomogeneous can not appear.
