Description

Technical Field

[0001] The utility model relates to the technical field of steering components of children's tricycles, and specifically provides a steering component of a children's tricycle. Background Art

[0002] The steering component of a children's tricycle is a structure that enables the overall movement of the children's tricycle in the direction according to the rider's will.

[0003] For example, a steering structure of a children's tricycle with the publication number of "CN205554430U" has a relatively simple structure and convenient operation. It can quickly switch from the child's own control of the front wheel steering to the parent's control of the steering from the rear push handle. It is flexible and can reduce some problems such as poor steering coordination and machining precision errors caused by the steering structure of the push handle controlling the front wheel, saving costs. The left and right steering angles are large, and it can turn 180° left and right, increasing the flexibility of turning and allowing turning in a very small space. However, in the use of the steering component of the children's tricycle, the position of the auxiliary control rod is in front of the chest of the riding child, which is prone to danger. Moreover, the children's tricycle is small in size, and parents cannot ride with the child. In addition, the specifications of the auxiliary control rod cannot be adjusted, increasing the difficulty of using the steering component of the children's tricycle and resulting in limitations in the use of the steering component of the children's tricycle. Summary of the Utility Model

[0004] The purpose of the present utility model is to solve the problem of increasing the difficulty of using the steering component of the children's tricycle, resulting in limitations in the use of the steering component of the children's tricycle, and to provide a steering component of a children's tricycle.

[0005] To achieve the above object, the present utility model provides the following technical solutions:

[0006] Design a steering component of a children's tricycle, including a vertical pipe and a second bolt. The upper and lower parts on the left side of the vertical pipe are respectively threadedly connected to the outer wall of the second bolt. The inner wall of the vertical pipe is inserted with the front fork of the children's tricycle. The upper left side of the vertical pipe is fixedly connected with a bracket. The top of the bracket is connected with a control structure, and the outer wall of the vertical pipe is connected with a docking structure.

[0007] Preferably, the control structure includes a cylinder and a first screw. The bottom of the outer wall of the cylinder is rotationally connected to the top notch of the bracket. The inner wall of the cylinder is threadedly connected to the outer wall of the first screw. The top of the first screw is rotationally connected to a handle.

[0008] Preferably, a second curved plate is fixedly connected to the lower right side of the cylinder.

[0009] Preferably, a first curved plate is fixedly connected to the upper part of the outer wall of the bracket.

[0010] Preferably, the right side of the outer wall of the second bolt is threadedly connected to the left circular opening of the front fork of the children's tricycle.

[0011] Preferably, the docking structure includes a sleeve and a straight pipe. The inner wall of the sleeve is rotatably connected to the outer wall of the vertical pipe. The right side of the sleeve is fixedly connected to the left side of the straight pipe. A first bolt is threadedly connected to the top of the straight pipe.

[0012] The steering assembly of a children's tricycle proposed by the present utility model has the beneficial effects that: by controlling the structure, the first screw rotates upward through the inner wall of the cylinder, increasing the length of the cylinder and the first screw to meet the height requirements of parents. Subsequently, the parent holds the handle and swings it left and right. In cooperation with the first screw and the cylinder, the bracket swings left and right. The swinging bracket causes the vertical pipe to rotate left and right within the inner wall of the sleeve, thereby causing the front fork of the inner children's tricycle to rotate left and right. This control method can not only enable children to ride, but also control the riding speed of the children's tricycle, and will not cause harm to children, reducing the usage difficulty of the steering assembly of the children's tricycle and eliminating the usage limitations of the steering assembly of the children's tricycle.
