Embodiment 1

[0019] Embodiment 1: see Figure 1-3 As shown, the anti-loosening nut body 1 and the dish nut 5 are all provided with threaded holes 2 that cooperate with the bolt 7; the lower end surface of the anti-loosening nut body 1 is provided with a limit groove 3; the dish nut 5 is conical as a whole; The nut 5 is placed in the limit groove 3; the outside of the disc nut 5 is a polygon; the polygon is provided with some disc nut outer telescopic slots 4; the threaded hole of the disc nut 5 is provided with some disc nut inner telescopic slots 6 ; The internal and external telescopic grooves of the disc nut 5 are arranged to facilitate expansion and contraction when the disc nut 5 is compressed, and enhance the fastening and anti-loosening effect;

[0020] see Figure 4 As shown, when in use, pass the bolt 7 through the fastened part 10 and the fastened part 1 9, and fix it with the common nut 1 8, after the butterfly nut 5 is fastened to the common nut 1 8, the locknut The body 1 co...

Embodiment 2

[0021] Embodiment 2: see Figure 5 As shown, the difference from Embodiment 1 is that after the bolt 7 is passed through the second fastener 10 and the first fastener 9, it is fixed directly with the wing nut 5, and then the locknut body 1 Compress the wing nut 5 tightly.

Embodiment 3

[0022] Embodiment 3: see Image 6 As shown, the difference from Example 1 is that, after the bolt 7 passes through the fastened part 10 and the fastened part 1 9, it is directly fixed with the wing nut 5, and then the ordinary bolt with a gasket is used to fix it. Thread two 11 compresses the wing nut 5.

Abstract

The invention discloses a threaded connection device with an anti-loosening function, and relates to the technical field of fastening devices. The threaded connection device comprises a lock nut body,a dish-shaped nut and a bolt, and the lock nut body and the dish-shaped nut are both provided with threaded holes matched with the bolt; and a limiting groove is formed in one end face of the lock nut body, the outer side of the dish-shaped nut is polygonal, a plurality of extendable grooves are formed in the outer side of the dish-shaped nut, and a plurality of extendable grooves are formed in an inner hole of the dish-shaped nut. According to the threaded connection device, the nut can be effectively prevented from loosening under the action of impact, vibration and variable load, and the safety is enhanced.

Description

technical field [0001] The invention relates to the technical field of fastening devices, in particular to a threaded connection device with an anti-loosening function. Background technique [0002] In the prior art, bolts, washers, and nuts are usually used to fasten the connected objects, which will not loosen automatically under static load conditions. However, due to the working conditions of the connection, there will inevitably be shocks, vibrations, and variable loads. Under these working conditions, the friction force between thread pairs will disappear or decrease instantaneously; at the same time, in the case of high temperature or large temperature change, the material will undergo creep and stress relaxation, which will also reduce the friction force. Under multiple actions, it will cause the connection to gradually loosen, resulting in a safety accident. Contents of the invention [0003] The object of the present invention is to provide a threaded connectio...
