detailed description

The technical solution of the utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

as shown in the picture 1~ picture 5 As shown, the children's tricycle of the present utility model includes a front fork assembly 1 , can be rotatably set on the front fork assembly 1 one of the lower front wheels of the 2 , and front fork assembly 1 Rotationally connected handle assembly 3 , seat components 4 , rear fork assembly 5 , can be rotatably set on the rear fork assembly 5 the rear two rear wheels 6 , handle assembly 3 It is used to control the direction of the children's tricycle.

front fork assembly 1 Includes front bracket 11 and retainer 12 , front wheel 2 with front bracket 11 The lower part of the rotating connection, the fixed sleeve 12 Set on the front bracket 11 The exterior of the upper, front bracket 11 Relatively fixed sleeve 12 Rotationally set, handle assembly 3 with front bracket 11 The upper part of the fixed connection, by turning the handle assembly 3 Can drive the front bracket 11 turn, thereby driving the front wheels 2 Turn to control the direction of the children's tricycle.

seat assembly 4 including seatpost 41 , fixed on the seat post 41 on the saddle 42 , fixed on the saddle 42 Connectors on 43 , seat post 41 the front part and the fixed sleeve 12 through the first axis 71 Phase rotation connection, rear fork assembly 5 with connectors 43 through the second axis 72 Phase rotation connection, first axis 71 and the second axis 72 Both extend in the left and right directions.

As a specific embodiment, the rear fork assembly 5 Includes rear brackets on the left and right sides of the children's tricycle 51 , at this time, the connector 43 set separately on the saddle 42 the left and right sides, the rear brackets on the left and right sides 51 The front part of the 43 through the second axis 72 Phase rotation connection, rear brackets on the left and right sides 51 Connectors 43 The joints extend backwards and toward the left and right sides of the children's tricycle, and the two rear wheels 6 Rear brackets set on the left and right sides respectively 51 of the rear.

As another specific embodiment, the rear fork assembly 5 Including the connection part, the front part and the rear part of the connection part are fixedly connected or the rear bracket is integrally arranged. At this time, the connection part 43 in saddle 42 The middle part of the rear part, the front part of the connecting part and the connecting part 43 through the second axis 72 The rear brackets are respectively located on the left and right sides of the children's tricycle, and extend backward from the connection with the connecting part and to the left and right sides of the children's tricycle respectively. The two rear wheels 6 Rear brackets set on the left and right sides respectively 51 of the rear.

The children's tricycle also includes a front fork assembly for 1 with seat assembly 4 A first lock mechanism locked in an unfolded state for locking the seat assembly 4 with rear fork assembly 5 Lock the second lock mechanism in the unfolded state.
