Description

Technical Field

[0001] This utility model relates to the field of roller technology, specifically to an anti-slip polyurethane roller. Background Technology

[0002] A roller is a mechanical component or sports device with multiple uses. Its specific form and function vary depending on the application scenario. Rollers will slip during use, so a non-slip polyurethane roller is required.

[0003] Existing rollers lack anti-slip mechanisms, which may cause them to slip during use, affecting their normal operation. Furthermore, their surfaces are frequently subjected to pressure during prolonged use, and without cushioning, this may cause damage and shorten their lifespan. Utility Model Content

[0004] The purpose of this utility model is to provide an anti-slip polyurethane roller to solve the problems mentioned in the background art, which are that existing rollers lack anti-slip mechanisms, which may cause slippage during use, thus affecting their normal use. Furthermore, during long-term use, their surfaces are often subjected to pressure, and if not cushioned, this may cause damage and affect their service life.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an anti-slip polyurethane roller, comprising a wheel axle, an inner wheel rotatably mounted on the surface of the wheel axle, a support plate fixedly mounted around the surface of the inner wheel, an outer wheel fixedly mounted on the surface of the support plate, an adhesive layer fixedly mounted on the surface of the outer wheel, a plastic layer fixedly mounted on the surface of the adhesive layer, a polyurethane layer fixedly mounted on the surface of the plastic layer, and a rubber layer fixedly mounted on the surface of the polyurethane layer.

[0006] Preferably, a serrated strip is fixedly mounted around the surface of the rubber layer, and the surface of the serrated strip is provided with annular grooves.

[0007] Preferably, a vertical rod is fixedly mounted around the surface of the inner wheel, and a vertical groove is opened inside the vertical rod. A movable plate is movably mounted inside each vertical groove. A spring is fixedly mounted between the movable plate and one side of the vertical groove, and the outer surface of the spring is movably connected to the inner surface of the vertical groove.

[0008] Preferably, both ends of the surface of the vertical rod are provided with sliding grooves, and a round shaft is movably installed inside each sliding groove, with one end of the round shaft being fixedly connected to one end of the movable plate.

[0009] Preferably, a top plate is fixedly installed around the inner surface of the outer wheel, and there are four top plates of the same size. Reinforcing ribs are also fixedly installed around the inner surface of the outer wheel.

[0010] Preferably, each side of the top plate is fixedly equipped with a vertical pole, and each side of the vertical pole is provided with a vertical groove, and the inner surface of the vertical groove is fixedly connected to the outer surface of the round shaft.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This type of anti-slip polyurethane roller features an adhesive layer that ensures a strong bond between layers during daily use, making the roller stable and slip-resistant. The plastic layer guarantees the roller's shape stability and a certain degree of rigidity. The polyurethane layer significantly enhances the roller's grip on the ground, effectively preventing slippage. The rubber layer has good elasticity and friction, adapting to different ground conditions and providing anti-slip properties. The serrated protrusions can embed into the ground, increasing the gripping force between the roller and the ground, effectively preventing roller slippage. The annular groove increases the surface roughness of the roller, thereby improving its anti-slip performance.

[0013] This type of anti-slip polyurethane roller, during daily use, causes a slight deformation of the top plate. The outer roller then causes the top plate to slide, which in turn causes the upright to slide on the surface of the vertical rod. At this point, the upright causes the round shaft to slide inside the groove, which in turn causes the moving plate to slide inside the vertical groove. Simultaneously, the moving plate compresses and squeezes the spring, thus buffering the compressive force and protecting the roller, thereby extending its service life. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: an anti-slip polyurethane roller, including an axle 1, with an inner wheel 2 rotatably mounted on the surface of the axle 1. The friction between the inner wheel 2 and the axle 1 is mainly rolling friction, which is smaller than sliding friction. This allows the roller to move more easily on the surface, thus achieving labor-saving and efficient transportation or transmission functions. A support plate 3 is fixedly mounted around the surface of the inner wheel 2. There are four support plates 3, and all four support plates 3 are the same size. An outer wheel 4 is fixedly mounted on the surface of the support plate 3. The design of the support plate 3 and the outer wheel 4 improves the strength of the roller, thereby increasing its service life. An adhesive layer 5 is fixedly mounted on the surface of the outer wheel 4, ensuring a strong bond between layers, making the roller stable and anti-slip. A plastic layer 6 is fixedly mounted on the surface of the adhesive layer 5, ensuring the shape stability and a certain rigidity of the roller. A polyurethane layer 7 is fixedly mounted on the surface of the plastic layer 6. 7 significantly enhances the grip between the roller and the ground, effectively preventing slippage. It is a high-molecular material with excellent mechanical properties, formed by the condensation reaction of polyols and polyisocyanates. Its elastomer properties are between those of plastics and rubber. It is oil-resistant, low-temperature resistant, and aging-resistant. The hardness can be adjusted by the raw materials to meet different needs. A rubber layer 8 is fixedly installed on the surface of the polyurethane layer 7. The rubber layer 8 has good elasticity and friction, which can adapt to different ground conditions and play an anti-slip role. A serrated strip 9 is fixedly installed around the surface of the rubber layer 8. The protrusions of the serrated strip 9 can embed into the ground, increasing the biting force between the roller and the ground. Especially on rough ground or in sloping environments, it can effectively prevent the roller from slipping. The surface of the serrated strip 9 is provided with annular grooves 10. The annular grooves 10 can increase the roughness of the roller surface. At the same time, when the roller rolls, it can play a role in draining water and removing debris, avoiding the reduction of friction between the roller and the ground due to water stains, debris, etc., thereby improving the anti-slip performance.

[0021] Four vertical rods 11 are fixedly mounted around the surface of the inner wheel 2. All four vertical rods 11 are of the same size. Vertical grooves 12 are formed inside each vertical rod 11, and movable plates 13 are movably mounted inside each groove 12. The outer surface of the movable plate 13 and the inner surface of the vertical groove 12 are both smooth, allowing the movable plate 13 to slide more smoothly within the groove 12 and reducing the likelihood of jamming. A spring 14 is fixedly mounted between the movable plate 13 and one side of the vertical groove 12, and the outer surface of the spring 14 is movably connected to the inner surface of the vertical groove 12. When the movable plate 13 slides inside the vertical groove 12, it compresses the spring 14, thus buffering the compressive force. Slide grooves 15 are formed at both ends of the surface of the vertical rod 11. A round shaft 16 is movably mounted inside each slide groove 15, and one end of the round shaft 16 is fixedly connected to one end of the movable plate 13. When the movable plate 13 slides, it drives the round shaft 16 within the slide groove 15. The sliding of the inner surface of the outer wheel 4 is stable due to the design of the groove 15 and the circular shaft 16. The inner surface of the outer wheel 4 is fixedly surrounded by a top plate 17. There are four top plates 17, and the four top plates 17 are the same size. When the outer wheel 4 slides, it will drive the top plates 17 to slide. The inner surface of the outer wheel 4 is fixedly surrounded by a reinforcing rib 18. The reinforcing rib 18 is designed in multiple sets. The design of the reinforcing rib 18 can improve the strength of the outer wheel 4. A vertical rod 19 is fixedly installed on one side of each top plate 17. A vertical groove 20 is opened on one side of each vertical rod 19. The inner surface of the vertical groove 20 is fixedly connected to the outer surface of the circular shaft 16. When the top plate 17 slides, it will drive the vertical rod 19 to slide on the surface of the vertical rod 11, and then drive the circular shaft 16 to slide. The inner surface of the vertical groove 20 and the outer surface of the vertical rod 11 are both smooth, which can make the vertical rod 19 slide more smoothly on the surface of the vertical rod 11 and reduce the occurrence of jamming.

[0022] Working principle: When the serrated blade 9 rolls on the ground, its protrusions can embed into the ground, increasing the biting force between the roller and the ground. Subsequently, the serrated blade 9 will squeeze the rubber layer 8, which in turn will squeeze the polyurethane layer 7. At this time, the polyurethane layer 7 will squeeze the plastic layer 6, which in turn will squeeze the adhesive layer 5. Then, the adhesive layer 5 will squeeze the outer wheel 4. Next, the outer wheel 4 will drive the top plate 17 to slide. Then, the top plate 17 will drive the upright 19 to slide on the surface of the vertical rod 11. At this time, the upright 19 will drive the round shaft 16 to slide inside the slide groove 15. Subsequently, the round shaft 16 will drive the moving plate 13 to slide inside the vertical groove 12. At the same time, the moving plate 13 will squeeze and compress the spring 14, which can buffer the squeezing force and protect the roller.
