[0003] A bearing usually consists of an inner ring, an outer ring, and rolling elements between the inner and outer rings. When assembling, the outer ring needs to be sleeved outside the inner ring and the rolling elements on the outer side of the inner ring. During the installation and actual use of the bearing, the outer ring may be deflected due to the force on a certain part of the outer ring edge, resulting in damage to the bearing and affecting the normal use effect of the bearing. Content of the Utility Model
[0004] The purpose of the utility model is to solve the problem that during the installation and actual use of the bearing, the outer ring may be deflected due to the force on a certain part of the outer ring edge, resulting in damage to the bearing and affecting the normal use effect of the bearing, and to propose an anti-slip bearing.
[0005] To achieve the above purpose, the utility model adopts the following technical scheme: an anti-slip bearing, including an inner ring, an outer ring, and a plurality of rolling elements. The rolling elements are located between the outer surface of the inner ring and the inner wall of the outer ring. A plurality of positioning structures are arranged on both sides of the inner ring. The positioning structure includes a slider. One end of the slider is fixedly connected with a sector rod. A plurality of sliding grooves are opened on both sides of the outer surface of the inner ring. The outer surface of the slider is slidably connected with the inner wall of the sliding groove. One end of the slider is provided with a spring. Both ends of the spring are fixedly connected with one end of the slider and one side of the inner wall of the sliding groove respectively.
[0006] The effects achieved by the above components are as follows: By setting the sector rod, when assembling the outer ring and the inner ring, the sliders on both sides of the outer surface of the inner ring can be pushed in the direction of the center of the inner ring to compress the springs inside the sliding grooves, causing the sector rods to contract. After installing the rolling elements and the outer ring outside the inner ring, the compressed springs inside the sliding grooves will return to their original state, pushing the sliders to drive the sector rods to move in the direction away from the center of the inner ring, so that the sector rods fit on one side of the inner ring and the outer ring. By further restricting the angle between the inner ring and the outer ring through the sector rods, it is possible to avoid the angle between the inner ring and the outer ring from being deflected during the installation of the bearing, which affects the normal use of the bearing.
[0007] Preferably, two inclined rods are fixedly connected to the outer surface of the slider, and the ends of the two inclined rods away from the slider are fixedly connected to one end of the sector rod.

Through the round rod, the angle between the slider and the inner ring of the chute can be further restricted, and the angle of the slider can be prevented from skewing as much as possible.
[0011] Preferably, the inner diameter of the spring is slightly larger than the diameter of the round rod, and the round rod is located inside the spring.
[0012] The effects achieved by the above components are as follows: When the spring expands and contracts, it will move on the outside of the round rod. Through the round rod, the internal shape of the spring can be strengthened, and the spring can be prevented from being distorted and affecting normal use as much as possible.
[0013] Preferably, a groove is formed at the top end of the slider, and a convex block is fixedly connected to one side of the top end of the slider close to the groove.
[0014] The effects achieved by the above components are as follows: When assembling the outer ring and the inner ring and it is necessary to control the movement of the sector rod, the finger can be placed against the groove at the top end of the slider to push the convex block, which is convenient for more easily controlling the slider to slide towards the center of the inner ring.
[0015] Preferably, an anti-slip structure is provided inside the inner ring. The anti-slip structure includes a circular ring. A plurality of convex strips are fixedly connected to the inner wall of the circular ring. A plurality of T-shaped rods are fixedly connected to the outer surface of the circular ring.

[0016] The effects achieved by the above components are as follows: By setting the circular ring, when installing the bearing on the shaft, the T-shaped rods on the outer surface of the circular ring can be first inserted into the respective slots at the inner ring, so that the card slots on the outer surface of the T-shaped rods are stuck on the card blocks on the inner wall of the slots, fixing the circular ring inside the inner ring. When connecting the shaft and the bearing, through the plurality of convex strips on the inner wall of the circular ring, the friction force when the inner wall of the circular ring contacts the surface of the shaft can be increased, so that the shaft drives the inner ring of the bearing to rotate without slipping easily.
[0017] Preferably, the card slot is a semi-circular slot, and the top and bottom edges of the card block are arc-shaped.
[0018] The effects achieved by the above components are as follows: By setting the semi-circular card slot and the arc-shaped top and bottom edges of the card block, it is easier for the T-shaped rod to be inserted into the slot and the card block to be stuck into the card slot.
[0019] Preferably, the inner wall of the circular ring is provided with a plurality of rectangular grooves, and the rectangular grooves are respectively located at the upper and lower sides of the inner wall of the circular ring.

[0029] Embodiment 1, as Figures 1-4As shown, an anti-skid bearing comprises an inner ring 1, an outer ring 5 and a plurality of rolling elements 4, wherein the rolling elements 4 are located between the outer surface of the inner ring 1 and the inner wall of the outer ring 5, and a plurality of positioning structures 2 are arranged on both sides of the inner ring 1, wherein the positioning structures 2 comprise a slider 22, wherein one end of the slider 22 is fixedly connected to a fan-shaped rod 23, and a plurality of slide grooves 21 are arranged on both sides of the outer surface of the inner ring 1, wherein the outer surface of the slider 22 is slidably connected to the inner wall of the slide groove 21, and a spring 24 is arranged at one end of the slider 22, wherein the two ends of the spring 24 are respectively fixedly connected to one end of the slider 22 and one side of the inner wall of the slide groove 21, and the outer ring 5 and the inner ring 1 are assembled by arranging the fan-shaped rod 23. When the inner ring 1 is in the state of being rotated, the spring 24 in the groove 21 is compressed to make the fan-shaped rods 23 shrink. When the rolling body 4 and the outer ring 5 are installed on the outer side of the inner ring 1, the spring 24 in the groove 21 is compressed to restore the original state and push the slider 22 to drive the fan-shaped rod 23 to move away from the center of the inner ring 1, so that the fan-shaped rod 23 fits on one side of the inner ring 1 and the outer ring 5. The angle between the inner ring 1 and the outer ring 5 is further limited by the fan-shaped rod 23, so as to avoid the angle between the inner ring 1 and the outer ring 5 from being skewed when the bearing is installed, which will affect the normal use of the bearing.
[0030] Reference Figures 2-4 As shown, in the present embodiment: two inclined rods 25 are fixedly connected to the outer surface of the slider 22, and one end of the two inclined rods 25 away from the slider 22 is fixedly connected to one end of the fan-shaped rod 23. By arranging the inclined rods 25, the connection between the slider 22 and the fan-shaped rod 23 can be reinforced, and the stability of the connection structure between the fan-shaped rod 23 and the slider 22 is improved. A round rod 26 is fixedly connected to one side of the inner wall of the slide groove 21, and the inner wall of the slider 22 slides on the outer surface of the round rod 26. When the slider 22 slides on the inner wall of the slide groove 21, it will slide on the outer surface of the round rod 26. The round rod 26 can further limit the angle between the slider 22 and the slide groove 21 and the inner ring 1, so as to avoid the angle of the slider 22 from being deflected as much as possible.
[0031] Reference Figures 2-4 As shown, in this embodiment: the inner diameter of the spring 24 is slightly larger than the diameter of the round rod 26, and the round rod 26 is located inside the spring 24. When the spring 24 is extended or contracted, it will move outside the round rod 26. The internal shape of the spring 24 can be reinforced by the round rod 26 to avoid the spring 24 from twisting and affecting normal use as much as possible. A groove 27 is provided at the top of the slider 22, and a protrusion 28 is fixedly connected to the side of the top of the slider 22 close to the groove 27. When the outer ring 5 and the inner ring 1 are assembled and the movement of the fan-shaped rod 23 needs to be controlled, the finger can be placed on the groove 27 at the top of the slider 22 to push the protrusion 28 to facilitate the slider 22 to slide toward the center of the inner ring 1.
[0032] Reference Figures 1-5As shown in the figure, in this embodiment: an anti-slip structure 3 is provided inside the inner ring 1. The anti-slip structure 3 includes a circular ring 35. A number of convex strips 36 are fixedly connected to the inner wall of the circular ring 35. A number of T-shaped rods 33 are fixedly connected to the outer surface of the circular ring 35. Card slots 34 are provided on both sides of the T-shaped rod 33. A number of insertion slots 31 are provided on the inner wall of the inner ring 1. Clamping blocks 32 are fixedly connected to both sides of the inner wall of the insertion slot 31. By providing the circular ring 35, when installing the bearing on the shaft, the T-shaped rods 33 on the outer surface of the circular ring 35 can be first inserted into the respective insertion slots 31 at the inner ring 1, so that the card slots 34 on the outer surface of the T-shaped rod 33 are stuck at the clamping blocks 32 on the inner wall of the insertion slot 31, fixing the circular ring 35 inside the inner ring 1. When connecting the shaft and the bearing, the number of convex strips 36 on the inner wall of the circular ring 35 can increase the friction force when the inner wall of the circular ring 35 contacts the surface of the shaft, so that the shaft drives the inner ring 1 of the bearing to rotate without slipping easily.
[0033] Referring to Figures 2-5 As shown in the figure, in this embodiment: the card slot 34 is a semi-circular slot, and the top and bottom edges of the clamping block 32 are arc-shaped. By providing the semi-circular card slot 34 and the top and bottom edges of the clamping block 32 being arc-shaped, it is easier for the T-shaped rod 33 to be inserted into the insertion slot 31 and the clamping block 32 to be stuck inside the card slot 34. A number of rectangular slots 37 are provided on the inner wall of the circular ring 35, and the rectangular slots 37 are respectively located on the upper and lower sides of the inner wall of the circular ring 35. When it is necessary to remove the circular ring 35 after installing the circular ring 35 inside the inner ring 1, the hand can be pressed against the rectangular slots 37 on the inner wall of the circular ring 35 to facilitate pushing the circular ring 35 to move and remove the circular ring 35.
[0034] Working principle: When assembling the bearing, first insert the T-shaped rods 33 on the outer surface of the circular ring 35 into the respective insertion slots 31 at the inner ring 1, so that the card slots 34 on the outer surface of the T-shaped rod 33 are stuck at the clamping blocks 32 on the inner wall of the insertion slot 31, fixing the circular ring 35 inside the inner ring 1. Subsequently, press the hand against the groove 27 at the top of the slider 22 to push the convex block 28 to control the slider 22 to slide towards the center of the inner ring 1, and compress the spring 24 inside the chute 21 to make each sector rod 23 contract. After installing the rolling elements 4 and the outer ring 5 outside the inner ring 1, the compressed spring 24 inside the chute 21 will return to its original state, pushing the slider 22 to drive the sector rods 23 to move away from the center of the inner ring 1, so that the sector rods 23 are attached to one side of the inner ring 1 and the outer ring 5. By further restricting the angle between the inner ring 1 and the outer ring 5 through the sector rods 23, the stability of the bearing during use is improved. Subsequently, connect the inner ring 1 of the bearing to the shaft. The number of convex strips 36 on the inner wall of the circular ring 35 can increase the friction force when the inner wall of the circular ring 35 contacts the surface of the shaft, so that the shaft drives the inner ring 1 of the bearing to rotate without slipping easily.
