Description

Technical Field

[0001] This utility model relates to the field of belt pulley technology, specifically a belt pulley with an anti-slip structure. Background Technology

[0002] Belt pulleys, belonging to the category of disc-hub parts, are generally relatively large in size and are primarily manufactured using casting and forging processes. Larger pulleys are typically designed for casting, usually using cast iron (due to its superior casting properties), and rarely cast steel (due to the poor casting properties of steel). Smaller pulleys can be designed for forging, using steel as the material. Belt pulleys are mainly used in long-distance power transmission applications, such as the power output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, power transmission in some low-horsepower motorcycles, power transmission in agricultural machinery, air compressors, reducers, speed reducers, generators, cotton gins, etc.

[0003] The prior art disclosure number CN222894603U discloses a pulley with an anti-slip structure, including a pulley body. Mounting rings are fixedly connected to the front and rear sides of the pulley body. Anti-slip components are provided on the left and right outer sides of the pulley body. Fixing components are provided at the front and rear of each anti-slip component. Each anti-slip component includes two convex ring sleeves. A connecting strip is fixedly connected to the end of the two convex ring sleeves closest to each other near the pulley body. Mounting strips are fixedly connected to the ends of the two convex ring sleeves furthest from each other near the pulley body. In this utility model, by integrating the convex ring sleeves, connecting strips, mounting strips, and positioning rods into a single design, and by providing anti-slip strips on the outside of the convex ring sleeves, connecting strips, and mounting strips, and by providing anti-slip pads on the outside of the anti-slip strips, the anti-slip structure of the pulley is simplified, the production cost of the anti-slip components is reduced, and the design is more practical.

[0004] With the above-described design, the existing pulley, through its integrated design of a convex ring sleeve, connecting strip, mounting strip, and positioning rod, and by adding anti-slip strips to the outer sides of the convex ring sleeve, connecting strip, and mounting strip, and further by adding anti-slip raised pads to the outer sides of the anti-slip strips, simplifies the anti-slip structure of the pulley, reduces the production cost of the anti-slip components, and makes it more practical. However, the existing pulley design has the following drawbacks during operation: In existing technology, the pulley requires multiple screws to fix the fixing component to the mounting ring. However, each side requires multiple screws, resulting in a large number of screws and a very troublesome fixing process. Furthermore, it requires the use of specialized tools to fix the screws, which is a waste of time and manpower. Moreover, the high-speed rotation of the pulley can cause the screws to loosen, and in severe cases, the screws may fall off. Utility Model Content

[0005] The present invention aims to provide a pulley with an anti-slip structure, which is mainly used to solve the technical problem of the prior art, which is very troublesome and time-consuming to fix the fixing components to the mounting ring with multiple screws, and requires the use of tools for fixing.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A pulley with an anti-slip structure includes a pulley body, mounting rings, and mounting plates. The mounting rings are symmetrically fixed on both sides of the pulley body. The outer wall of the mounting rings has mounting grooves. The mounting plates are symmetrically slidably connected to the mounting grooves. The inner wall of the mounting grooves has symmetrical limiting grooves. The inner wall of the mounting plates is fixedly connected to a limiting plate, which is inserted into the limiting grooves. One side of the mounting plate has a movable groove. The inner wall of the movable groove is equipped with a limiting component to restrict the movement of the mounting plate. One end of the outer wall of the mounting plate has a sliding groove, and the other end of the outer wall of the mounting plate has a fixing groove. The inner wall of the sliding groove is equipped with a fixing component.

[0007] The working principle and beneficial effects of this utility model: 1. Working principle: When it is necessary to install and fix the mounting plate, first insert the mounting plate with the limiting plate into the mounting slot, so that the limiting plate is inserted into the limiting slot. The mounting plate is fixed by the limiting component, and then the two mounting plates are fixed by the fixing component to complete the installation.

[0008] 2. Beneficial effects: Existing technology, through an integrated design of the convex ring sleeve, connecting strip, mounting strip, and positioning rod, and by adding anti-slip strips on the outer sides of the convex ring sleeve, connecting strip, and mounting strip, and further adding anti-slip convex pads on the outer sides of the anti-slip strips, simplifies the anti-slip structure of the pulley, reduces the production cost of the anti-slip components, and addresses a more practical technical problem. However, existing pulleys require multiple screws to fix the fixing components to the mounting ring during use. Multiple screws are needed on each side, resulting in a large number of screws, a cumbersome fixing process, and the need for specialized tools, which is time-consuming and labor-intensive. Furthermore, the screws can loosen under high-speed rotation of the pulley. In severe cases, this can lead to screws coming loose. This solution addresses this by using a mounting plate, mounting slot, limiting plate, limiting slot, limiting component, and fixing component. The mounting plate with the limiting plate is inserted into the mounting slot, allowing the limiting plate to fit into the limiting slot. The limiting plate then engages with the limiting slot to initially fix the mounting plate. Finally, the fixing rod and fixing slot on the fixing component secure the two mounting plates, improving their stability. Installation requires no tools and can be completed by one person, making it very convenient. Disassembly is simple: first pull the fixing plate to disengage it from the fixing slot, then press the push plate and pull the mounting plate to complete the disassembly. This is a very convenient technical solution.

[0009] Preferably, the limiting component includes a limiting plate, which is slidably connected to the inner wall of the movable groove. Multiple limiting springs are fixedly connected to the inner wall of the movable groove, with the other end of each spring fixedly connected to the limiting plate. A limiting groove corresponding to the limiting plate is formed on the inner wall of the mounting groove. The limiting plate is inserted into the limiting groove. A sliding plate is slidably connected to the inner wall of the limiting groove, abutting against the limiting plate. A push plate is fixedly connected to the other side of the sliding plate, passing through and slidably connecting to the mounting ring. By setting the limiting component, the mounting plate can be initially fixed, ensuring it is securely fixed inside the mounting ring. When the mounting plate is fixed inside the mounting ring, the limiting springs are in a relaxed state.

[0010] Preferably, the fixing component includes a slide rod that is slidably connected to the inner wall of the slide groove. A fixing spring is fixedly connected to the inner wall of the slide groove, and the other end of the fixing spring is rotatably connected to the slide rod. A fixing plate is fixedly connected to the end of the slide rod away from the fixing spring, and a fixing rod is fixedly connected to the lower surface of the other end of the fixing plate. The fixing rod is inserted into the fixing groove. By setting up the fixing component, the mounting plate can be fixed in a secondary way, making the mounting plate more secure and preventing it from falling off. When the fixing rod is inserted into the fixing groove, the fixing spring is relaxed.

[0011] Preferably, the side of the limiting plate that contacts the sliding plate has an arc-shaped groove, and an arc-shaped magnet is fixed to the inner wall of the arc-shaped groove. The arc-shaped magnet attracts the sliding plate. By setting the arc-shaped groove and the arc-shaped magnet, the limiting plate can attract the sliding plate, making the insertion of the limiting plate into the limiting groove more stable.

[0012] Preferably, the outer wall of the mounting ring has symmetrical moving grooves that communicate with the limiting grooves. A moving plate is slidably connected to the inner wall of the moving groove, and the moving plate is fixedly connected to the push plate. By setting the moving groove and the moving plate, the moving plate can prevent the push plate from sliding into the limiting groove, and the moving groove can store the moving plate so that the moving plate does not bulge out, thus preventing the moving plate from being squeezed when the pulley is placed on the ground.

[0013] Preferably, the upper surface of the fixing plate is provided with a groove. By providing a groove, the fixing plate can be moved by pulling, which is more convenient.

[0014] Preferably, the inner wall of the limiting plate has a guide slope to facilitate the installation of the mounting plate. Attached Figure Description

The mounting plate 3 has a movement limiting assembly, which includes a limiting plate 10. The limiting plate 10 is slidably connected to the inner wall of the movable groove 7. Multiple limiting springs 11 are fixedly connected to the inner wall of the movable groove 7. The other end of each limiting spring 11 is fixedly connected to the limiting plate 10. The inner wall of the mounting groove 4 has a limiting groove 12 corresponding to the limiting plate 10. The limiting plate 10 is inserted into the limiting groove 12. A sliding plate 13 is slidably connected to the inner wall of the limiting groove 12. The sliding plate 13 abuts against the limiting plate 10. The limiting plate 10 and the sliding plate... An arc-shaped groove 19 is formed on one side of the sliding plate 13 in contact with the sliding plate 13. An arc-shaped magnet 20 is fixedly connected to the inner wall of the arc-shaped groove 19. The arc-shaped magnet 20 attracts the sliding plate 13. A push plate 14 is fixedly connected to the other side of the sliding plate 13. The push plate 14 passes through the mounting ring 2 and is slidably connected to it. A symmetrical moving groove 21 is formed on the outer wall of the mounting ring 2. The moving groove 21 is connected to the limiting groove 12. A moving plate 22 is slidably connected to the inner wall of the moving groove 21. The moving plate 22 is fixedly connected to the push plate 14. One end of the outer wall of the mounting plate 3 is open A sliding groove 8 is provided, and a fixing groove 9 is provided on the outer wall of the other end of the mounting plate 3.

[0019] As can be seen from the above, the specific embodiments of this utility model are as follows: (The anti-slip structure in the comparative document is prior art and will not be described in detail in this technical solution.) When the mounting plate 3 needs to be installed and fixed, the mounting plate 3 with the limiting plate 6 is first inserted into the mounting groove 4, so that the limiting plate 6 is inserted into the limiting groove 5. At this time, the guide slope on the limiting plate 10 in the mounting plate 3 is squeezed, so that the limiting plate 10 slides in the movable groove 7 and squeezes the limiting spring 11. When the limiting plate 6 is fully inserted into the limiting groove 5, the limiting plate 10 corresponds to the limiting groove 12. At this time, under the action of the rebound force of the limiting spring 11, the limiting plate 10 is pushed to move, so that the limiting plate 10 is inserted into the limiting groove. Inside 12, the limiting plate 10 pushes the slide plate 13 to move, which in turn pushes the push plate 14 to move, causing the push plate 14 to push the moving plate 22 to slide inside the moving groove 21, thus fixing the mounting plate 3 for the first time. Then, the pull groove on the fixing plate 17 is pulled, causing the fixing plate 17 to move with the slide rod 15, which stretches the fixing spring 16. Then, the fixing plate 17 is rotated, causing it to move the fixing rod 18, which is positioned directly above the fixing groove 9. Then, the fixing plate 17 is released, allowing the fixing rod 18 to insert into the fixing groove 9, thus fixing the two mounting plates 3 for the second time and completing the installation.
