[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] The present invention will be further described below with reference to the embodiments.

[0021] Example: Refer to Figures 1 to 3 A manually adjustable tensioning wheel includes a first tensioning wheel 1 and a second tensioning wheel 2. A transmission belt 3 is rotatably sleeved on the outer sides of the first tensioning wheel 1 and the second tensioning wheel 2. The first tensioning wheel 1 and the second tensioning wheel 2 constitute the core part of the tensioning device, and are respectively responsible for contacting the transmission components to perform the tensioning function. The transmission belt 3 plays a driving role in the transmission system to ensure that the first tensioning wheel 1 and the second tensioning wheel 2 can operate effectively.

[0022] It also includes a fixed plate 5, with a mounting assembly 4 at the end of the fixed plate 5 away from the first tensioning wheel 1. A lifting plate 6 is vertically slidably connected to the fixed plate 5, and the lifting plate 6 passes through the fixed plate 5. A connecting plate 7 is fixedly connected to the end of the lifting plate 6 near the first tensioning wheel 1. Multiple auxiliary springs 8 are fixedly connected between the connecting plate 7 and the fixed plate 5. An auxiliary wheel 11 is also rotatably connected to the end of the lifting plate 6 near the first tensioning wheel 1, and the auxiliary wheel 11 is located below the connecting plate 7. The auxiliary wheel 11 and the connecting plate 7 are spaced apart. When the auxiliary wheel 11 abuts against the transmission belt 3, all the auxiliary springs 8 are in a stretched state. Under the elastic force, the auxiliary wheel 11 maintains an upward trend, ensuring the tension of the transmission belt 3, the fit between the transmission belt 3 and the first tension wheel 1 and the second tension wheel 2, and ensuring its transmission effect. The auxiliary wheel 11 is located below the connecting plate 7 and contacts the transmission belt 3. When the auxiliary wheel 11 abuts against the transmission belt 3, multiple auxiliary springs 8 will be stretched, providing elasticity and precision for adjustment. The auxiliary springs 8 are used to maintain precise control of the tension force and ensure that the tension wheel can run smoothly during adjustment. The design of multiple auxiliary springs 8 makes the adjustment process more stable, while ensuring that the system has sufficient elasticity to cope with different working conditions.

[0023] The fixed plate 5 has two guide holes 9. The upper end of the connecting plate 7 is fixedly connected to two guide rods 10 that are slidably connected to the guide holes 9. On the one hand, this ensures the stability of the sliding of the connecting plate 7. On the other hand, the auxiliary spring 8 is set on the outside of the guide rods 10, which can increase the service life of the auxiliary spring 8.

[0024] The mounting assembly 4 includes a vertical plate 41. Both ends of the vertical plate 41 are provided with multiple sliding grooves. Limiting springs 42 are fixedly connected in the sliding grooves. The other end of the limiting springs 42 is fixedly connected to a clamping plate 43. Multiple guide grooves communicating with the sliding grooves are also provided in the vertical plate 41. Multiple sliding rods 44 that are slidably connected to the guide grooves are fixedly connected to one end of the clamping plate 43 near the vertical plate 41. The sliding rods 44 are provided to ensure the stability of the sliding of the clamping plate 43.

[0025] When using the mounting assembly 4, pull the two clamping plates 43 back to back to increase the distance between the two clamping plates 43. The multiple limit springs 42 are further stretched, and the two clamping plates 43 are relaxed. Under the elastic force of the multiple limit springs 42, the two clamping plates 43 clamp the fixing objects near the first tensioning wheel 1 and the second tensioning wheel 2, thus completing the fixing of the auxiliary wheel 11.

[0026] Multiple limiting springs 42 are arranged one-to-one on the outside of the sliding rod 44, which avoids the limiting springs 42 from easily undergoing elastic deformation and increases the service life of the limiting springs 42.

[0027] The limiting spring 42 is always in a stretched state, and the limiting spring 42 is never in a state of extreme stretching, which avoids the limiting spring 42 from easily developing elastic fatigue and further increases the service life of the limiting spring 42.

[0028] The working principle of this utility model is as follows:

[0029] First, pull the two clamping plates 43 back to back to increase the distance between the two clamping plates 43. The multiple limit springs 42 are further stretched, and the two clamping plates 43 are relaxed. Under the elastic force of the multiple limit springs 42, the two clamping plates 43 clamp the fixing objects near the first tensioning wheel 1 and the second tensioning wheel 2, thus completing the installation of the auxiliary wheel 11.

[0030] After installation, the auxiliary wheel 11 abuts against the transmission belt 3, and all the auxiliary springs 8 are in a stretched state. Under the elastic force of the auxiliary springs 8, the auxiliary wheel 11 maintains an upward movement trend, ensuring the tension of the transmission belt 3, ensuring the fit between the transmission belt 3 and the first tensioning wheel 1 and the second tensioning wheel 2, ensuring its transmission effect, providing adjustment elasticity and precision, and ensuring that the first tensioning wheel 1 and the second tensioning wheel 2 can run smoothly during adjustment. The design of multiple auxiliary springs 8 makes the adjustment process more stable, while ensuring that the system has sufficient elasticity to cope with different working conditions, preventing the transmission belt 3 from loosening from the first tensioning wheel 1 and the second tensioning wheel 2, and avoiding slippage that would affect the operation.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
