Description

Technical Field

[0001] The invention belongs to the technical field of rotary adjustment mechanism equipment, and in particular relates to a rotary adjustment mechanism and a rotatable adjustable lamp. Background Art

[0002] A rotational adjustment mechanism refers to a mechanism that rotates a device or equipment for adjustment. At present, there are three common rotational adjustment methods on the market: 1. A rotational adjustment method that uses a spring elastic washer plus a flat washer and then locks with a screw; this method relies on the elastic tension of the spring elastic washer for rotational adjustment. The spring elastic washer is compressed during adjustment, and the adjustment piece is pressed by the reverse force of the spring elastic washer after adjustment. This is commonly seen in lamp head adjustment of lamps, lazy stands for mobile phones and tablets, etc.; 2. The two parts have an interference fit, and rotational adjustment is performed based on the elasticity and plasticity of the material itself. This method is commonly seen in the adjustment of universal joints and some plastic connections; 3. By adding a spring or spring sheet to the shaft, a reaction force is generated when the spring is squeezed to press the adjustment piece and the fixing piece for rotational adjustment; this is commonly seen in flip phones, notebook shafts, and other occasions.

[0003] However, the first adjustment method has the problem that the spring elastic washer will become fatigued after multiple adjustments, and the elasticity of the spring elastic washer cannot be effectively guaranteed, resulting in adjustment failure. When the weight of the adjustment part is heavy, the failure rate of the spring elastic washer will increase; the second adjustment method can only be used in occasional adjustments due to interference fit, and is not suitable for some occasions that require frequent adjustments; the third adjustment method has a single application occasion and produces less damping, and is only suitable for rotational adjustment of lightweight products; therefore, it is necessary to design a new rotational adjustment mechanism to address the limitations of the current common rotational adjustment methods. Summary of the invention

[0004] The purpose of the embodiments of the present invention is to provide a rotation adjustment mechanism, aiming to solve the problems raised in the above background technology.
