Description

Technical Field

[0001] This utility model relates to the field of belt pulley technology, and in particular to a belt pulley that can prevent belt loosening. Background Technology

[0002] Pulleys, belonging to the category of disc-hub parts, are generally relatively large in size. They are mainly manufactured using casting and forging processes. Pulleys are primarily used for long-distance power transmission, such as the power output of small diesel engines, agricultural vehicles, tractors, automobiles, mining machinery, machining equipment, textile machinery, packaging machinery, lathes, forging machines, and the power transmission of some low-horsepower motorcycles.

[0003] Belt drive, as one of the most commonly used mechanical transmission methods, occupies an important position in industrial production. During operation, the speed of the pulley is relatively high. Since the existing pulley is located on the relatively smooth wall of the belt assembly section, the structural stability of the assembly section is poor, and it is easy to fall off. There is room for optimization. Therefore, it is necessary to design a pulley that can prevent belt loosening to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this invention is to provide a pulley that can prevent belt slippage, so as to solve the problem of easy slippage mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a pulley that can prevent belt loosening, comprising a pulley body and a limiting seat, wherein the limiting seat is uniformly connected to one side of the pulley body; Each limiting seat has a threaded groove inside, and a threaded rod is threadedly connected inside each threaded groove. A bracket is connected to the inner side of each threaded rod, and a limiting wheel is rotatably connected to the inner side of each bracket. Each limiting seat has an installation groove inside. Mounting blocks are evenly fixed to the inner side of the pulley body, and each mounting block is connected to the mounting groove. A threaded head is fixed to the outer side of each mounting block, and a threaded cap is threadedly connected to the outer side of each threaded head. Wheel grooves are evenly provided on the outer side of the pulley body.

[0006] Furthermore, two sets of the limiting seats are provided, and the limiting seats are arranged in an alternating manner on one side of the pulley body.

[0007] Furthermore, the pulley body is uniformly fixed with reinforcing ribs inside, and the reinforcing ribs are arranged in a ring shape inside the pulley body.

[0008] Furthermore, each of the threaded rods is fixed with a knob, and each knob has an anti-slip texture on its outer side.

[0009] Furthermore, each of the limiting seats has a limiting groove on its inner side, and each of the brackets has a limiting block fixed on one side that matches the limiting groove.

[0010] Furthermore, a gasket is provided on the inner side of each threaded cover, and the gasket is in contact with the limiting seat.

[0011] Furthermore, the size of the mounting groove is matched with the size of the mounting block, and the cross-section of both the mounting groove and the mounting block is set to be circular.

[0012] Compared with the prior art, the beneficial effect of this utility model is that the belt pulley that can prevent belt loosening achieves the function of limiting and preventing loosening; By setting a limiting seat and assembling it with the pulley body through the mounting block and mounting groove, and tightening the threaded cover for limiting, the knob is turned during use. The threaded connection of the threaded groove drives the threaded rod to move, which drives the bracket and the limiting wheel to move synchronously. By adjusting the height of the limiting wheel, it can be adapted to belts of different thicknesses. At the same time, it can also limit the belt in both the lateral and longitudinal directions. Thus, by setting a lateral mechanical limiting mechanism, the belt is prevented from running off track and falling off through physical blocking, while maintaining transmission efficiency.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0017] Please see Figures 1-5 One embodiment of this utility model is a pulley that can prevent belt loosening, comprising a pulley body 1 and a limiting seat 3; Two sets of limit seats 3 are provided, and the limit seats 3 are arranged in a staggered manner on one side of the pulley body 1; Specifically, such as Figure 2 As shown, when in use, the staggered arrangement of the limiting seats 3 can achieve bidirectional restriction; The inside of the pulley body 1 is uniformly fixed with reinforcing ribs 14, and the reinforcing ribs 14 are arranged in a ring shape inside the pulley body 1. Specifically, such as Figure 1 As shown, during use, the structural strength of the pulley body 1 can be improved by the reinforcing rib 14; Limiting grooves 12 are provided on the inner side of each limiting seat 3, and a limiting block matching the limiting groove 12 is fixed on one side of each bracket 9. Specifically, such as Figure 4 As shown, during use, the limiting block and the limiting groove 12 can serve as a limiting and guiding mechanism when the bracket 9 moves. One side of the pulley body 1 is evenly connected to a limiting seat 3, and each limiting seat 3 is provided with a threaded groove 7 inside; A knob 4 is fixed to the outside of each threaded rod 8, and the outside of each knob 4 is provided with anti-slip texture. Specifically, such as Figure 4 As shown, the anti-slip texture on the outside of knob 4 improves the anti-slip effect when turning knob 4 during use. Furthermore, each of the threaded grooves 7 is threadedly connected to a threaded rod 8, and each of the threaded rods 8 is connected to a bracket 9 on its inner side. Each of the brackets 9 is rotatably connected to a limit wheel 10, and each of the limit seats 3 is provided with an installation groove 11. The size of the mounting groove 11 is matched with the size of the mounting block 13, and the cross-sections of the mounting groove 11 and the mounting block 13 are both set to be circular. Specifically, such as Figure 5 As shown, when in use, by matching the size of the mounting slot 11 with the size of the mounting block 13, the connection effect of the bracket 9 can be improved; Mounting blocks 13 are evenly fixed on the inner side of the pulley body 1, and the mounting blocks 13 are all connected to the mounting groove 11. Threaded heads 6 are fixed on the outer side of the mounting blocks 13, and threaded caps 15 are threadedly connected to the outer side of the threaded heads 6. Gaskets 5 are provided on the inner side of the threaded cap 15, and the gaskets 5 are in contact with the limiting seat 3; Specifically, such as Figure 1 and Figure 5 As shown, during use, the gasket 5 can further prevent the threaded cap 15 from loosening after it is fixed.

[0018] Working principle: When in use, the limiting seat 3 is assembled with the pulley body 1 via the mounting block 13 and mounting groove 11. The threaded cover 15 is tightened for limiting. During use, rotating the knob 4 drives the threaded rod 8 to move through the threaded connection of the threaded groove 7, which in turn drives the bracket 9 and the limiting wheel 10 to move synchronously. By adjusting the height of the limiting wheel 10, it can be adapted to belts of different thicknesses. At the same time, it can also limit the belt in the lateral and longitudinal directions, that is, prevent the belt from running off track and falling off through physical blocking, while maintaining transmission efficiency.
