Description

Pillow frame assembly structure of baby carriage ball

The present invention relates to a pedestal assembly structure for a baby carriage ball wheel, and in particular to a yoke assembly using a baby carriage ball wheel, the yoke assembly can be an innovative structural designer for improving the stability and grounding of the overall bicycle.

According to the rims used in baby carriages, most of them are re-assembled pneumatic tires or solid tires by using a wire wheel, that is, a combination of a wire and a rim, and a whole plate and a rim are used to assemble the pneumatic tire or For solid tires, the width of the tire is related to the grounding area of the overall stroller wheel. The actual grounding width of the stroller currently on the market varies with the curve of the tire section, but because it is either a wire wheel or a plate wheel. They are all flat-shaped wheels. They are still flat after being fitted with tires. Therefore, no matter how to increase the grounding width, the stability during driving is still limited, especially the baby carriages controlled by young children, even if they are changed to the front and rear two-wheelers. When cornering, there is still the danger of dumping during riding.

Therefore, in view of the problems existing in the above-mentioned conventional structure, how to develop an innovative structure that is more ideal and practical, and to use the eagerly awaited by consumers, is also the goal and direction of the relevant industry to strive to develop breakthroughs. In view of this, the creator has been engaged in the manufacturing development and design experience of related products for many years. After the detailed design and careful evaluation of the above objectives, the creator will have a practical and practical creation.

That is, the main purpose of the present invention is to provide a structure of a pedestal assembly for a baby carriage ball; the problem to be solved is that the conventional baby carriage is a flat wheel, whether it is a wire wheel or a plate wheel. After being fitted with a tire, it is still flat, so no matter how to increase the grounding width, the stability during driving is still limited, especially the baby carriage controlled by the young child. Even if it is changed to the front and the rear two-wheeled vehicle, there is still a ride in the corner. The problem of the danger of the mid-dumping is improved and the breakthrough is made; and the technical feature of solving the problem is mainly by including a frame, and the frame has a wheel frame unit at the front fork and the rear fork respectively, the wheel frame unit The utility model comprises a wheeled rod, wherein the left and right sides of the wheel frame rod are respectively symmetrically arranged with a yoke assembly; wherein the yoke assembly comprises a hollow shaft assembly, the shaft assembly is internally provided with a shaft assembly, and the shaft assembly is centrally pivoted a spindle having an external thread shape, the screw shaft of the shaft assembly is provided at one end thereof, and the spindle is screwed to the screw lock member, and the male shaft has a convex shaft portion protruding from one end of the screw lock member. The The shaft shaft set is a protrusion of one of the axle plates, and the bearing is internally provided with a bearing, wherein the bearing is provided with an axial hole, and the shaft hole is pivoted to the convex shaft portion of the spindle, and The wheel disc is in the form of a circular disc body, and the other end of the wheel disc is formed with a ball and socket surface; thereby, the innovative and unique design enables the creation of the ball to make the shock absorption performance better when the child rides. It is the use of the good stability and grounding of the ball wheel, which can effectively improve the safety of riding, and the overall structure can reach its practicality, which makes the creation novel and progressive, and can greatly increase the added value of the baby carriage product. .
