Description

A liftable auxiliary wheel connecting device

technical field

The utility model relates to a connection device for a liftable auxiliary wheel, which belongs to the accessory system of a complete vehicle.

Background technique

At present, most of the existing auxiliary wheel connecting devices for vehicles adopt an integral structure, and the height of the auxiliary wheel cannot be adjusted after the auxiliary wheel is installed. Always at the same height, training wheels for special requirements are no longer applicable.

Contents of the invention

In order to solve the above technical deficiencies, the utility model provides an auxiliary wheel connecting device with simple design, flexible operation, adjustable auxiliary wheel height, and convenient installation and disassembly.

The utility model is achieved through the following measures:

The lifting auxiliary wheel connecting device of the present utility model includes a fixing assembly, a connecting assembly and a pin shaft. cylinder, the fixed cylinder and the connecting cylinder are provided with several height adjustment holes with different heights, and the diameter of the pin shaft is smaller than the diameter of the height adjustment hole.

In the lifting auxiliary wheel connecting device of the utility model, the end of the pin shaft is provided with a cotter pin hole.

In the lifting auxiliary wheel connecting device of the present utility model, fixing holes are arranged on the shelf plate.

The beneficial effect of the utility model is that the adjustment of the height of the auxiliary wheel can be realized conveniently through simple plugging of pin shafts, and the operation is simple and flexible.

In the figure: 1 fixed assembly, 2 connecting assembly, 3 pin shaft, 4 height adjustment hole, 5 cotter pin hole, 6 fixing hole.

Detailed ways

As shown in Figures 1, 2, and 3, the liftable auxiliary wheel connection device of the present invention includes a fixed assembly 1, a connecting assembly 2 and a pin shaft 3, and the fixed assembly 1 is fixed on the frame at the lower end of a vertical fixed cylinder. On the plate, reinforcing ribs are set between the side of the fixed cylinder and the frame plate to play the role of reinforcement. The connecting assembly 2 adopts a simple connecting cylinder, which can be set inside or outside the fixing cylinder. Wherein the fixed cylinder and the connecting cylinder adopt square or circular cylindrical shapes, and several height adjustment holes 4 with different heights are arranged on the fixed cylinder and the connecting cylinder, and the height adjustment holes 4 correspond to each other on the wall of the cylinder. The diameter of the pin shaft 3 is smaller than the diameter of the height adjustment hole 4 . A split pin hole 5 is provided at the end of the pin shaft 3 for fixing the pin shaft 3 .

Its working principle is: the fixing assembly 1 is fixed through the fixing hole 6 provided on the shelf plate, and the connecting assembly 2 is connected with the auxiliary wheels. When in use, the connecting cylinder of the connecting assembly 2 is set inside or outside the fixing cylinder. Select an appropriate position, align the connecting cylinder with the height adjustment hole 4 on the fixed cylinder, then pass the pin shaft 3 through the aligned height adjustment hole 4 at the same time, and insert a pin into the cotter pin hole 5 at the end of the pin shaft 3 to fix it . The connection height of the connection assembly 2 can be adjusted by passing the pin shaft 3 through the height adjustment holes 4 of different heights, thereby adjusting the height of the auxiliary wheels.
