Embodiment Construction

[0027] In order to further understand the content of the invention, characteristics and effects of the present invention, the following examples are described in detail as follows:

[0028] See Figure 1 to Figure 3 , One end of the threaded connector of the present invention is a supporting portion, and the other end is a connecting portion. The connection part includes a self-adjusting elastic ring 3 located on the outside, which bulges outward under the action of an axially compressed external force to form an elastic ring 9 of the outer drum, and a threaded rod 4 located on the inside.

[0029] like Figure 7 and Figure 8 As shown in , the self-adjusting elastic ring 3 includes a plurality of elastic pieces 7 distributed along the circumferential direction, a wedge-shaped relief groove 8 is formed between two adjacent elastic pieces 7, and there is a gap between each elastic piece 7 and the threaded rod 4 and Each elastic sheet 7 is bent toward the threaded rod 4 . Wh...

Abstract

The invention belongs to the technical field of threaded connectors, in particular to a highly shock-resistant self-adjusting elastic threaded connector. One end is a supporting part, and the other end is a connecting part; the connecting part includes a self-adjusting elastic ring (3) located on the outside, which bulges outward under the action of an axially compressed external force to form an outer drum elastic ring (9), and a self-adjusting elastic ring (3) located on the outside The inner threaded rod (4); the self-adjusting elastic ring (3) includes a plurality of elastic sheets (7) distributed along the circumferential direction, and a wedge-shaped relief groove (8) is formed between two adjacent elastic sheets (7), each elastic There is a gap between the sheet (7) and the threaded rod (4), and each elastic sheet (7) is bent toward the threaded rod (4). The invention provides a high-seismic self-adjusting elastic threaded connector with simple and reasonable structural design, which minimizes the mass when ensuring sufficient high toughness, and has the functions of maintaining sufficient compression force and automatic adjustment at any time during the working process. The present invention also relates to a processing method and a using method of the above threaded connector.

Description

technical field [0001] The invention belongs to the technical field of threaded connectors, in particular to a highly shock-resistant self-adjusting elastic threaded connector. The present invention also relates to a processing method and a using method of the above-mentioned highly shock-resistant self-adjusting elastic threaded connection. Background technique [0002] In the design of aerospace vehicle parts, a large number of fasteners are usually used as the connection between components, and high-performance fasteners are very expensive. During the flight of an aerospace vehicle, it vibrates all the time, and when there is vibration, there will be alternating force, especially the vibration generated by this alternating force will lead to loosening and failure of the product, or even fatigue failure. At present, it is the way to install elastic washers in this situation, and this technical problem is solved by adding elastic washers before and after the bolt. However...
