Abstract

The present invention provides a universal wheel spraying protection device, which is composed of a chassis, springs, a cone shaft, a tray, sliding blocks and composite tensioning sleeves. When the universal wheel spraying protection device is in use, a wheel is placed on a conical surface of an upper end of the tray, supporting springs are compressed by self weight of the wheel, and the tray is pressed down under the action of guiding columns and guiding sleeves; meanwhile, each sliding block drives the corresponding composite tensioning sleeve to move outwards under the action of the cone shaft; after a central hole is tensioned, the sliding blocks stops radial movement, and the tray also stops axial movement; and at this time, the central hole is protected by the composite tensioning sleeves, and a flange face is protected by the conical surface of the tray.

First claim

What is claimed is:

1. A universal wheel spraying protection device, comprising:
a chassis, guiding sleeves, guiding columns, supporting springs, a cone shaft, a tray, reset springs, sliding blocks and composite tensioning sleeves;
characterized in that the cone shaft is mounted at a central position right above the chassis;
the guiding sleeves are uniformly distributed and fixed on the chassis in a circumference direction;
the guiding columns matching with the guiding sleeves are mounted under the tray;
the supporting springs coat outer sides of the guiding columns and are arranged between the chassis and the tray;
the sliding blocks matching with a conical surface of an upper end of the cone shaft are mounted in corresponding T-shaped sliding slots of the chassis;
the composite tensioning sleeves are fixed on the sliding blocks; and
the reset springs are mounted in the corresponding T-shaped sliding slots of the chassis and are arranged at a back of the sliding blocks.

2. The universal wheel spraying protection device according to claim 1 , wherein a number of the guiding sleeves and a number of the guiding columns are three, and a number of the sliding blocks and a number of the composite tensioning sleeves are in one-to-one correspondence and are not less than four.

3. The universal wheel spraying protection device according to claim 1 , wherein matching parts of the composite tensioning sleeves are overlapped with each other.

4. The universal wheel spraying protection device according to claim 1 , wherein an upper end face of the tray is conical.
