Detailed Description

The utility model will be further described with reference to the accompanying figures 1-2.

Referring to fig. 1 and 2, an embodiment of the utility model provides a hair-winding prevention universal wheel, which comprises a U-shaped shaft bracket 1, a tire 2, a wheel shaft 3 for rotatably connecting the tire 2 to the U-shaped shaft bracket 1, and a dustproof end cover 4 arranged at the axial side of the tire 2; the tire 2 is arranged in the opening of the U-shaped shaft bracket 1, and two dustproof end covers 4 are arranged at two ends of the tire 2 respectively so as to perform dustproof partition on the bearing in the tire 2.

All be provided with a plurality of blades 5 at the both ends of shaft 3, and the equal circumference of a plurality of blades 5 sets up in the radial side of shaft 3, and blade 5 can be dismantled and connect in dust cover 4 to butt U-shaped pedestal 1, make blade 5 can rotate along with the rotation of dust cover 4. The blade back of the blade 5 is abutted against the side wall of the wheel shaft 3, namely the cutting edge faces to the radial direction of the wheel shaft 3, so that hair wound by taking the wheel shaft 3 as a central shaft is cut off by the blade 5; simultaneously, because blade 5 rotates along with the rotation of dust cover 4 for it is better relatively to cut off the effect, thereby improves among the prior art that the universal wheel is easily died by the hair card, leads to clearing up inconveniently, uses inconvenient problem.

The side wall of the dust-proof end cover 4 is also provided with a plurality of mounting grooves 41.

Referring to fig. 2, in particular, the blade 5 includes a cutting portion 51 and two mounting portions 52, and the two mounting portions 52 are respectively disposed at both ends of the cutting portion 51 to facilitate mounting. Cutting part 51 is provided with the cutting edge to cut off hair, and along cutting part 51's cutting edge direction, cutting part 51's size reduces to the middle-end along the both ends that are close to installation department 52 gradually, thereby the blade slope at cutting part 51 both ends forms the guide effect, makes the hair of twining in cutting part 51 when tightening up, can be guided and by quick cutting off, thereby further improves the effect of cutting off.

One of the mounting portions 52 is adapted and inserted into the mounting groove 41 so as to drive the blade 5 to rotate by the rotation of the dust cap 4. And the mounting part 52 is provided with the isolating blocks 521, so that the rotating isolating blocks 521 form an isolating effect in the rotating process of the blade 5 so as to prevent hair from entering the mounting groove 41; the side of the mounting portion 52 away from the dust-proof end cap 4 is an inclined surface to form a guiding function for the hair entering the cutting portion 51, thereby facilitating the rapid cutting of the hair.

And the other mounting part 52 is provided with a connecting ring 522, and the connecting ring 522 is simultaneously connected to the mounting parts 52 and simultaneously abutted against the wheel shaft 3 and the U-shaped shaft bracket 1 so as to increase the connection strength between the blades 5 and ensure that the blades 5 rotate along with the rotation of the dust-proof end cover 4. The side of the connection ring 522 departing from the U-shaped shaft bracket 1 is a slope to form a guiding effect for hair, and prevent hair from entering into the gap between the connection ring 522 and the U-shaped shaft bracket 1.

When the mounting device is mounted, the mounting portion 52 is inserted into the mounting groove 41, the U-shaped shaft frame 1 is arranged at the end portion of the tire 2, and the wheel shaft 3 is passed through the U-shaped shaft frame 1, the tire 2 and the plurality of blades 5 and fixed.
