Embodiment Construction

[0026] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Such as Figure 1-6 As shown, an anti-loosening internal thread member provided by the embodiment of the present invention includes a body 1, a first screw hole 8 is opened on the body 1, an axial groove 4 is opened on the inner wall of the first screw hole 8, and an axial groove 4 is opened on the inner wall of the first screw hole 8. A locking piece 3 is embedded in the groove 4 , a second screw hole 2 is opened on the side wall of the body 1 , and a locking screw 5 is screwed in the second screw hole 2 , and the tail end of the locking screw 5 abuts against the locking piece 3 .

[0028] Specifically, the body 1 can be any structure provided with threaded holes, such as nuts, threaded pipes, and various parts or machines provided with s...

Abstract

The invention discloses an anti-loose internal threaded part and a screw joint device. The anti-loose internal threaded part comprises a body, wherein a first screw hole is formed in the body, an axial groove is formed in the inner wall of the first screw hole, and a locking piece is embedded in the axial groove; a second screw hole is formed in the side wall of the body, a locking screw is arranged in the second screw hole in a screw joint mode, and the tail end of the locking screw abuts against the locking piece. According to the anti-loose internal threaded part, when an external threaded part is screwed in the first screw hole, the locking screw is screwed down to press the locking piece, so that the locking piece located on the first screw hole presses the external threaded part and large static friction force is generated between the locking piece and the external threaded part, and then it is guaranteed that relative movement of the anti-loose internal threaded part and the external threaded part is avoided under vibration. Compared with a spring washer in the prior art, the anti-loose internal threaded part has the advantage that due to the fact that the locking piece and the locking screw are fixed to the body of the anti-loose internal threaded part, the application range is wider.

Description

technical field [0001] The invention relates to the mechanical field, in particular to an anti-loosening internal threaded part and a screw connection device. Background technique [0002] The screw connection structure includes externally threaded parts and internally threaded parts that are screwed together, such as screws and nuts. The screw connection structure is one of the basic mechanical connection structures, and it is widely used in most industrial fields. [0003] The disadvantage of the screw connection structure is that it is easy to loosen or even fall off when encountering vibration. The main anti-loosening screw connection design in the prior art is an elastic washer. The elastic washer is placed on the base using the screw connection structure. The internal threaded part continuously compresses the elastic washer during the process of screwing the external threaded part, so that the internal threaded part During use, it is continuously under the elastic pre...
