Seat Connection Mechanism

technical field

The invention relates to the technical field of child seats, in particular to a seat connection mechanism for connecting a seat and supporting feet of a child seat.

Background technique

Child seats are indispensable specialized furniture in families with children, and various child seats are increasingly popular among home users and are widely used. At present, child seats can be divided into two types: detachable and non-detachable. Among them, the non-detachable child seat occupies more space due to its large size and is not convenient for transportation and storage. seat replaced. However, for existing detachable child seats, the structure of the connecting mechanism used to connect the seat and the supporting legs is generally more complicated, and the operation of the connecting process is also relatively troublesome, and generally all need to manipulate a handle or handle by hand. button to complete the connection process that secures the seat to the support feet.

Therefore, it is necessary to provide a seat connection mechanism with simple structure and easy operation during connection.

Contents of the invention

The object of the present invention is to provide a seat connection mechanism with simple structure and easy operation during connection.

In order to achieve the above object, the present invention provides a seat connecting mechanism for connecting the seat and supporting legs of a child seat, the seat connecting mechanism includes a connecting piece, a fixing seat, a snap-fitting piece and an elastic piece. The fixing base is fixed on the supporting foot, the connecting piece is fixed on one of the seat base and the fixing base, and the engaging piece is slidably arranged on the seat base and the fixing base. On the other hand, the elastic member is arranged at one end of the engaging member so that the engaging member has a tendency to engage with the connecting member after the fixing seat is connected to the seat, and the engaging The piece has a sliding block and an engaging hook, the engaging hook is fixedly connected to the sliding block, the engaging hook is engaged with the connecting piece, the seat connecting mechanism has a plurality of the engaging pieces, A plurality of the engaging parts are distributed in a circle, the connecting part is a ring-shaped engaging edge, the engaging edge is engaged with the engaging hook, and the connecting element is fixed on the seat the bottom of the bottom, the engaging part is slidably arranged on the fixed seat, the extending direction of the engaging hook is perpendicular to the sliding direction of the sliding block and the upper end of the engaging hook has an escape slope, the The bottom surface of the fixed seat is provided with a sliding groove, and the sliding groove extends radially along the circumference formed by the plurality of engaging parts, and the sliding groove is provided with a sliding hole passing through the upper surface of the fixed seat. The sliding block is slidably arranged in the sliding groove, and the engaging hook protrudes out of the upper surface of the fixing seat through the sliding hole.

Compared with the prior art, since the present invention fixes the fixing base on the supporting foot, the connecting piece is fixed on one of the seat base and the fixing base, and the fixing base and the chair The other one of the seats is slidably provided with the engaging member, and the elastic member is arranged at one end of the engaging member, and the chair seat can be realized by engaging the engaging member with the connecting member. The connection with the supporting legs has a simple structure; when connecting the seat and the supporting legs, the seat is moved to the fixed seat on the supporting legs, the connecting part pushes the engaging part, and the The engaging member slides outward and compresses the elastic member, and when the seat seat touches the fixed seat, the elastic member drives the engaging member to engage with the connecting member to complete the seat and supporting legs The whole process only needs to move the seat down, and there is no need to manipulate other parts, so the connection operation is very simple.
