Description

A directional self-locking nut

technical field

The utility model belongs to the field of aviation fasteners, in particular to a directional self-locking nut.

Background technique

In the prior art, when connecting a structure with a wedge surface, the sloped connection surface must be spot-faced at the part where the nut is used to form a plane, and the traditional bolt and nut connection (see Figure 1) is used. This connection requires changing the connecting piece The thickness of the joint may affect the strength of the connecting piece, increase the operation time and affect the work efficiency. There is a need for a nut that can be directly installed on an inclined plane to overcome the above disadvantages.

Contents of the invention

Purpose of the invention: to propose a directional self-locking nut, which is used to connect a connecting surface with a slope.

Technical solution: a directional self-locking nut, including a self-locking nut 1 and a washer 2, the self-locking nut 1 is a spherical self-locking nut, the washer 2 is an inner spherical washer, and the spherical diameter of the spherical self-locking nut is the same as the inner spherical surface The spherical surface of the gasket has a uniform diameter.

Beneficial effects: the utility model adopts a directional nut structure composed of a spherical self-locking nut and an inner spherical washer, which can be installed on a slope of up to 6°. This connection form does not need to change the thickness of the connecting piece and does not affect the strength of the connecting piece , while saving operating time and improving work efficiency.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings, please refer to Fig. 1 to Fig. 4 .

A kind of orientation self-locking nut, comprises self-locking nut 1 and washer 2, described self-locking nut 1 is spherical self-locking nut, and described washer 2 is inner spherical washer, and the spherical surface diameter of spherical self-locking nut and the spherical surface of inner spherical washer Consistent diameter.

The utility model selects a directional nut, which is composed of a spherical self-locking nut and an inner spherical washer, and the utility model deviates from the axis by a maximum of 6° (see Figure 2).

The utility model adopts a directional nut structure composed of a spherical self-locking nut and an inner spherical washer, and can be installed on a slope of up to 6°. This connection form does not need to change the thickness of the connecting piece, does not affect the strength of the connecting piece, and saves Operating time, improve work efficiency.

Claims (1)

1. A directional self-locking nut, comprising a self-locking nut [1] and a washer [2], characterized in that, the self-locking nut [1] is a spherical self-locking nut, and the washer [2] is an inner spherical washer , the spherical diameter of the spherical self-locking nut is consistent with the spherical diameter of the inner spherical washer.
