[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1-4 As shown, this utility model is a novel pulley assembly, including an adjusting gear assembly 1, an adjusting limit assembly 2 installed at the front end of the adjusting gear assembly 1, the adjusting limit assembly 2 being limited and installed inside the adjusting sleeve assembly 3, a locking assembly 4 being installed on the outer side of the adjusting sleeve assembly 3, and the bottom of the locking assembly 4 being correspondingly disposed on the inner wall of the adjusting gear assembly 1.

[0026] The adjusting gear assembly 1 includes a limiting side plate 101, a pulley 102 is connected to the inner side of the limiting side plate 101, and an adjusting lock plate 103 is connected to the end of the pulley 102.

[0027] The adjusting locking plate 103 is installed on the inner side of the telescopic sleeve 301. The adjusting gear assembly 1 is the core component, including the pulley 102 and the adjusting locking plate 103. When it is necessary to adjust the position of the pulley 102, the adjusting locking plate 103 is driven by external operation, such as manual or tool operation, so that it slides within the telescopic sleeve 301. The movement of the adjusting locking plate 103 drives the pulley 102 to move synchronously, thereby realizing the adjustment of the pulley position.

[0028] The adjusting limiting assembly 2 includes a limiting cavity 201, which is formed on both inner walls of the adjusting locking plate 103. A return spring 202 is installed inside the limiting cavity 201, and a limiting post 203 is installed at the end of the return spring 202. The adjusting limiting assembly 2 achieves a limiting function during adjustment by engaging the limiting post 203 with the limiting tooth groove 303 in the adjusting sleeve assembly 3. When the adjusting locking plate 103 moves, the limiting post 203, under the action of the return spring 202, engages with the limiting tooth groove 303, ensuring that the pulley 102 can stably remain at the preset position during adjustment.

[0029] The adjusting sleeve assembly 3 includes a telescopic sleeve 301, the inner wall of which is provided with an adjusting inner wall 302, and a limiting tooth groove 303 is provided on the adjusting inner wall 302, and a limiting post 203 is provided in the limiting tooth groove 303 for corresponding limiting.

[0030] The locking component 4 includes a mounting screw 401, which is opened on the outer wall of the telescopic sleeve 301. A threaded rod 402 is installed inside the mounting screw 401. A rotating handle 403 is connected to the top of the threaded rod 402, and the bottom of the threaded rod 402 is correspondingly set inside the positioning hole 404, which is opened on the outer wall of the pulley 102.

[0031] A silicone ring 4041 is installed around the positioning hole 404. The silicone ring 4041 is connected to the outer wall of the pulley 102. When the pulley 102 is adjusted to the target position, the threaded rod 402 is driven to move downward by rotating the handle 403. The bottom of the threaded rod 402 is inserted into the positioning hole 404 on the outer wall of the pulley 102, achieving mechanical locking. The design of the silicone ring 4041 enhances the sealing of the positioning hole 404, preventing dust or foreign objects from entering, and also improves the stability of the locking.

[0032] In use, the adjusting gear assembly 1 is the core component, including the pulley 102 and the adjusting locking plate 103. When the position of the pulley 102 needs to be adjusted, the adjusting locking plate 103 is driven by external operation, such as manual or tool operation, causing it to slide within the telescopic sleeve 301. The movement of the adjusting locking plate 103 drives the pulley 102 to move synchronously, thereby adjusting the position of the pulley. The adjusting limit assembly 2, through the cooperation of the limiting post 203 and the limiting tooth groove 303 in the adjusting sleeve assembly 3, realizes the limiting function during the adjustment process. When the adjusting locking plate 103 moves, the limiting post 203, under the action of the return spring 202, engages with the limiting tooth groove 303, ensuring that the pulley 102 can stably stay in the preset position during the adjustment process. The design of the limiting tooth groove 303 allows for multiple adjustment positions, and the user can fix the pulley 102 in a suitable position as needed. The locking assembly 4 is used to fix the position of the pulley 102 and prevent it from shifting during operation. Once the pulley 102 is adjusted to the target position, rotating the handle 403 drives the threaded rod 402 downwards. The bottom of the threaded rod 402 inserts into the positioning hole 404 on the outer wall of the pulley 102, achieving mechanical locking. The design of the silicone ring 4041 enhances the sealing of the positioning hole 404, preventing dust or foreign objects from entering, while also improving the stability of the lock. During adjustment, the pulley 102 is moved by operating the adjusting locking plate 103. The limiting pin 203 engages sequentially in the limiting tooth groove 303, ensuring the stability and accuracy of the adjustment process. When the pulley 102 reaches the target position, rotating the handle 403 of the locking assembly 4 causes the threaded rod 402 to insert into the positioning hole 404, completing the locking. The pulley 102 operates normally in the locked state, transmitting power or adjusting the transmission ratio. Through the cooperation of the limiting tooth groove 303 and the limiting pin 203, multi-level precise adjustment is achieved. The design of the locking assembly 4 and the silicone ring 4041 ensures the stability of the pulley 102 during operation. This design allows for simple operation; adjustment and locking are accomplished through simple mechanical operations, requiring no complex tools. This pulley assembly is suitable for mechanical equipment requiring frequent adjustments to belt position or transmission ratio, such as industrial transmission systems, agricultural machinery, and automated equipment. Its precise adjustment and stable locking characteristics make it particularly suitable for high-precision applications. Through the above working principle, this new pulley assembly achieves efficient, stable, and convenient adjustment functions, meeting the high requirements of modern mechanical equipment for transmission systems.
