Detailed Description

In order to make the technical means and the technical effects achieved by the technical means of the present invention clearer and more complete, the following embodiments are provided and are described in detail with reference to the accompanying drawings as follows:

as shown in fig. 3 to 9, an adaptive support wheel 2 structure of the present embodiment, which is installed on a bed frame of a diagnostic bed, is used for installing and supporting a bed plate 1, and includes a fixed base 3 fixed in the bed frame, a swinging component installed on the fixed base 3, and a support wheel 2 installed on the swinging component and capable of rolling; the connection part of the fixed seat 3 and the bed frame is provided with a height adjusting component. The height adjusting assembly is arranged on the fixing seat 3 of the supporting wheel 2, so that assembling deviation in the height direction can be compensated. The swing assembly on the fixing seat 3 can limit the degree of freedom of the supporting wheel 2 in the vertical direction, and the supporting effect is achieved. In addition, the swing assembly releases the constraint of the supporting wheel 2 along the circumferential direction, allows the supporting wheel 2 to rotate along the circumferential direction, and the rotation can automatically adapt to the change of the circumferential angle between the supporting wheel 2 and the bed plate 1.

The swinging assembly comprises a U-shaped swinging arm 4 and a mandrel 5 fixed with two ends of the U-shaped swinging arm 4; the bottom of the U-shaped swing arm 4 is rotatably connected with the fixed seat 3 and can swing along two ends of the fixed seat 3.

The height adjusting assembly includes long holes 9 opened in the height direction at both ends of the holder 3, and bolts 10 installed in the long holes 9 and fixed with the frame, so that the height of the supporting wheels 2 can be adjusted.

In order to make the movement smoother, the mandrel 5 is sleeved with a sliding shaft sleeve 6, and the supporting wheel 2 is sleeved on the sliding shaft sleeve 6 to reduce the friction during rotation.

An end cover 8 is arranged at the joint of the bottom of the U-shaped swing arm 4 and the fixed seat 3. The end caps 8 are used to restrict the movement of the support wheels 2 in the circumferential direction (the direction of movement of the bed plate 1).

Two ends of the mandrel 5 are fixedly connected with two ends of the U-shaped swing arm 4 through pins 7, so that the supporting wheel 2 is prevented from transversely moving.

The above is a detailed description of the technical solutions provided in connection with the preferred embodiments of the present invention, and it should not be assumed that the embodiments of the present invention are limited to the above description, and it will be apparent to those skilled in the art that the present invention can be implemented in a variety of ways without departing from the spirit and scope of the present invention.
