Embodiment 1

[0045] Such as Figure 1 to Figure 4 , Figure 6As shown, the combined connector includes a nut body 1 and a washer 2. The nut body 1 has a washer retaining edge 1a for blocking the washer 2. The combined connector also includes an elastic ring 3 with a variable inner diameter. The elastic ring 3 is sleeved on the On the nut body 1, the nut body 1 has a limiting portion 1b that restricts the axial movement of the elastic ring 3. The limiting portion 1b can prevent the elastic ring 3 from detaching from the nut body 1. The inner wall of the washer 2 has a flared shape toward the elastic ring 3. The minimum inner diameter of the gasket 2 is smaller than the minimum outer diameter of the elastic ring 3 on the working surface 2a. When the gasket 2 has a tendency to disengage, the working surface 2a can squeeze the elastic ring 3, so that the elastic ring 3 has a tendency to be tightened. It is artificially stipulated that one end on which the elastic ring 3 is installed on the nu...

Embodiment 2

[0049] Such as Figure 5 and Figure 7 As shown, the difference between this embodiment and the first embodiment is that the limiting part 1b is annular and has a flaring-shaped acting surface 1b1 on the top, the elastic ring 3 is placed on the acting surface 1b1, and the acting surface 1 2a It is opposite to the flaring direction of the acting surface 1b1. The action surface 1b1 is set as a constricted shape opposite to the flared shape, and a recessed accommodation groove 1b1a is formed between the reverse necked-shaped action surface 2 1b1 and the nut body 1, and a part of the elastic ring 3 is located in the accommodation groove 1b1a, When the active surface 1b1 squeezes the elastic ring 3, the accommodation groove 1b1a has a limiting effect on the elastic ring 3, and can play a role in preventing the elastic ring 3 from detaching. Adaptive changes will not be repeated here, and are common knowledge of those skilled in the art.

Abstract

The invention provides a combined connector, and belongs to the field of connectors. The combined connector includes a nut body and a washer, the nut body is provided with a washer retaining edge forblocking the washer, the combined connector further includes an elastic ring with the changeable inner diameter, the elastic ring is arranged on the nut body in a sleeving mode, the nut body is provided with a limiting part for limiting the axial movement of the elastic ring, the limiting part can prevent the elastic ring from separating from the nut body, the inner wall of the washer is providedwith a first acting surface expanding towards the direction of the elastic ring, the minimum inner diameter in the washer is smaller than the minimum outer diameter of the elastic ring, and when the washer has a tendency of separation, the first acting surface can extrude the elastic ring, so that the elastic ring has a tendency of being clamped. The combined connector solves the problems such asthe unstable connection between an existing washer and the nut body and easy falling off.

Description

technical field [0001] The invention belongs to the field of connectors and relates to combined connectors. Background technique [0002] Combination nut is a commonly used connecting piece, also known as hub nut or sleeve nut. Anti-loosening combination nut is one of the common types of nuts. Its structure mainly includes nut body and washer, and the washer is circumferentially connected to the nut On the body, the washer plays an indispensable role as a positioning part when the reinforced nut body is tightened and a loosening part after tightening. However, due to the special installation place of the combined nut, vibration occurs from time to time, resulting in a gap between the washer and the nut body. There is often an axial relative force between the washers and the nut body due to the design defects of the corresponding structure of the current combined nut, which easily leads to the separation of the washer and the nut body. [0003] For example, the application n...
