Problems solved by technology

But the shortcoming of this stroller is that when the baby stroller pushes the handle to change direction, the conversion of the universal direction and directional movement of the wheel must be realized through the control part on the push handle and the cooperation of the pull cord and the control part of the wheel. With the conversion of directional movement, this design not only has a complex design structure, but also has m

Embodiment Construction

[0027] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] Such as Figure 1 to Figure 12As shown, the universal and directional automatic conversion mechanism of the trolley wheel in this embodiment includes an upper bracket 1, a lower bracket 2, and a rotating shaft 3 for connecting the wheels. The wheels are arranged on both ends of the rotating shaft 3, A wheel is fixed with the rotating shaft, and in order to fix the wheel with the rotating shaft 3 more conveniently, a wheel frame 31 is fixed on the rotating shaft 3, and the wheel is inserted together with the wheel frame 31 sleeves through the jack on the side and is fixed. The upper bracket 1 is fixed to the foot bar 4, the rotating shaft 3 is rotatably placed on both sides of the rear of the lower bracket 2, and the lower part of the foot bar 4 pushes up from the front of the lower bracket 2. The surface penetrates into the inner cavit...

Abstract

An automatic switching mechanism for universal movement and directional movement of cart wheels comprises an upper support (1), a lower support (2) and a rotary shaft (3), the upper support (1) and a cart foot rod (4) are fixed, the rotary shaft (3) rotatably penetrates through the two side faces of the lower support (2), the lower portion of the cart foot rod (4) is detachably connected with the lower support (2) through the top face of the front portion of the lower support (2), the lower support (2) can horizontally rotate with the cart foot rod (4) as a center, an inserting column (5) capable of vertically moving is arranged in the lower support (2), the upper end of the inserting column (5) can stretch out of a top face hole (20) of the lower support (2) and can be inserted and buckled with a bottom face hole (11) of the upper support (1), the inserting column (5) drives a drive gear (61) and mesh gears (71) to be in linkage through saw-shaped teeth (51), a damper (6) which rotates and slips together with the rotary shaft (3) is arranged on the rotary shaft (3), and the drive gear (61) is connected with the damper (6). The automatic switching mechanism has the advantages that when the direction of a push handle of a cart is changed, the rear wheels are automatically locked and make the directional movement, and the front wheels are automatically unlocked and make the universal movement.
