[0007] In order to solve the above technical problems, the utility model provides a tensioning wheel anti-skid bearing, comprising: a bearing body, wherein the bearing body comprises an outer ring;

[0008] A plurality of stop blocks are provided, each of which is arranged on the outside of the outer ring, and each of the stop blocks is distributed in an annular shape with equal spacing and with the central axis of the outer ring as the center of the circle.

[0009] Preferably, the outer side of the outer ring is provided with a plurality of sliding grooves which are distributed in an annular shape with equal intervals and whose center is the central axis, and a sliding opening is provided inside the sliding groove on one side close to the outer side of the outer ring, and the stop block is integrally slidingly arranged in the sliding opening, and both sides of the stop block are provided with limit blocks which are integrally formed with the stop block, and a coil spring is arranged inside the sliding groove.

[0010] Preferably, the outer side of the stop block is arc-shaped.

[0011] Preferably, both ends of the outer side of the outer ring are provided with embedding grooves.

[0012] Preferably, both ends of the outer side of the outer ring are provided with anti-slip grooves.

[0013] Preferably, the bearing body further comprises an inner ring and a retaining frame, the inner ring is entirely arranged inside the outer ring, a plurality of rollers are arranged between the outer ring and the inner ring, and each roller is mounted on the retaining frame.

[0014] 3. Beneficial Effects

[0015] Compared with the prior art, the utility model has a slot on the inner side wall of the tensioning wheel that is compatible with the stop block, the entire bearing is pressed into the tensioning wheel through a press, and the stop block is snapped into the slot. Due to the setting of the stop block, the tensioning wheel and the outer ring will not rotate relative to each other, thereby improving the anti-slip performance.

[0016] Furthermore, when installing the brake block, first place the ring spring into the sliding groove, insert the stop block obliquely into the sliding groove, and then adjust it so that the limit block of the stop block contacts the inner wall of the sliding groove. It can be seen that the installation process of the stop block is convenient and quick, and it is easy to replace. When the entire bearing is pressed into the tensioning wheel through a press, the stop block is first pressed into the outer ring to reduce the pressing resistance of the bearing, which makes it easier for the entire bearing to be pressed into the tensioning wheel.

[0023] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0024] like Figure 1-4 As shown, a tension wheel anti-skid bearing of this embodiment includes a bearing body, and the bearing body includes an outer ring 1;

[0025] A plurality of stop blocks 7 are provided, each of which is arranged on the outside of the outer ring 1, and each of the stop blocks 7 is distributed in a ring shape with equal intervals, with the central axis of the outer ring 1 as the center of the circle. A groove matching the stop block 7 is provided on the inner wall of the tensioning wheel. The entire bearing is pressed into the tensioning wheel by a press, and the stop block 7 is inserted into the groove. Due to the setting of the stop block 7, the tensioning wheel and the outer ring 1 will not rotate relative to each other, thereby improving the anti-slip property.

[0026] Specifically, the outer side of the outer ring 1 is provided with a plurality of sliding grooves 9 with its central axis as the center and distributed in an equidistant ring shape, and a sliding opening is provided inside the sliding groove 9 on one side close to the outer side of the outer ring 1. The overall sliding arrangement of the stop block 7 is arranged in the sliding opening, and both sides of the stop block 7 are provided with limit blocks 10 with an integral structure therewith. A ring spring 8 is arranged inside the sliding groove 9. When installing the stop block 7, the ring spring 8 is first placed in the sliding groove 9, and the stop block 7 is inserted obliquely into the sliding groove 9, and then adjusted so that the limit block 10 of the stop block 7 contacts the inner wall of the sliding groove 9. It can be seen that the installation process of the stop block 7 is convenient and quick, and it is easy to replace. When the entire bearing is pressed into the tensioning wheel by a press, the stop block 7 is first pressed into the outer ring 1 to reduce the pressing resistance of the bearing, which facilitates the entire bearing to be pressed into the tensioning wheel.

[0027] Specifically, the outer side of the stop block 7 is in an arc shape, and the arc shape makes it easier for the stop block 7 to be inserted into the interior of the tensioning wheel.

[0028] Specifically, both ends of the outer side of the outer ring 1 are provided with embedding grooves 6, and the inner side of the tensioning wheel is provided with protrusions adapted to the embedding grooves 6 to further improve the lateral anti-slip performance. Both ends of the outer side of the outer ring 1 are provided with anti-slip patterns 5 for increasing friction.

[0029] Meanwhile, the bearing body further comprises an inner ring 2 and a retaining frame 3 . The inner ring 2 is entirely arranged inside the outer ring 1 . A plurality of rollers 4 are arranged between the outer ring 1 and the inner ring 2 . Each roller 4 is mounted on the retaining frame 3 .

[0030] In the utility model, the ring spring 8 is first placed in the sliding groove 9, the stop block 7 is obliquely inserted into the sliding groove 9, and then adjusted, the limit block 10 of the stop block 7 contacts the inner wall of the sliding groove 9, and the installation is completed. The inner side wall of the tensioning wheel is provided with a groove adapted to the stop block 7, the entire bearing is pressed into the tensioning wheel through a press, and the stop block 7 is snapped into the groove. Due to the setting of the stop block 7, the tensioning wheel and the outer ring 1 will not rotate relative to each other.

[0031] The above are only preferred implementations of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
