Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a damping shaft bracket. Background Art

[0002] The pivot bracket is a common mechanical structural component, widely used in various mechanical equipment, electronic products and industrial equipment. Its main function is to provide rotation support and fixation, making the movement of the equipment more stable and precise. With the development of science and technology, the design and manufacturing technology of the pivot bracket is constantly improving, and its application range is also constantly expanding.

[0003] In order to make the bracket have stronger supporting force and stability, the shaft usually has a damping function. A common way is to use a finished damping shaft and fix it to the bracket body with screws.

Another way is to use a non-damping shaft, fix it to the bracket body with screws, apply external force to make the parts in close contact, thereby increasing the friction between the contact surfaces to enhance the damping effect. However, the screw clamping method requires regular inspection and maintenance to ensure that the screws are properly tightened. After long-term use, the screws may loosen due to vibration and use, resulting in a weakening or loss of the damping effect, which requires retightening. Utility Model Content
