Description

Technical Field

[0001] The utility model relates to the technical field of clothes dryers, in particular to a tensioning and adjusting mechanism for a drum. Background Art

[0002] The tensioning mechanism on the existing dryer, for example, the Chinese utility model patent (publication number CN219218491U) is named Tensioning Mechanism and Clothes Processing Equipment. In the above mechanism, the two ends of the tension spring are fixed between the motor frame and the base, and the tension adjustment cannot be performed. After using for a period of time, the transmission effect of the motor output is reduced due to the decrease in the elasticity of the tension spring and the tension of the synchronous belt, which ultimately leads to a decrease in the rotation efficiency of the drum, affecting the overall drying effect. Utility Model Content

[0003] The technical problem to be solved by the utility model is that the existing tension spring cannot be adjusted, which affects the rotation efficiency of the drum and the overall drying effect. In order to overcome the defects of the above-mentioned prior art, the present invention provides a connection strength that can be enhanced by an adjusting rod, and the adjusting rod can be rotated and adjusted to achieve adjustable tension of the tension spring, thereby ensuring stable transmission efficiency and transmission effect, and ultimately ensuring the overall drying effect.

[0004] For the purpose of this utility model, the following technical solutions are adopted:

After the synchronous belt is tensioned, the connecting screw is tightened to fix the two ends of the adjusting rod to the front plate and the rear plate respectively, so that the tension adjustment is convenient, and the negative impact caused by the decrease in the elasticity of the tension spring and the tension of the synchronous belt after a period of use is prevented.

The first ear plate and the second ear plate facilitate the installation of the pin, and the rotation through hole facilitates the rotation connection of the swing arm, thereby improving the rotation flexibility.

[0011] Preferably, both left and right sides of the adjusting rod are bent upward to form supporting vertical plates, so as to further improve the overall supporting performance and structural strength of the adjusting rod.
