Problems solved by technology

[0003] (1) When the mechanical anti-loosening nut is in use, only one side of the thread is always in contact with the threaded part of the mechanical anti-loosening nut. In this way, during the long-term high-frequency vibration operation, the nut still has the defect of loosening, and it cannot be permanently anti-loosening Purpose;
[0004] (2) The existing lock nuts have complex structures and relatively large dimensions, which cannot meet the requirements for use in locations with limited installation space, and have poor adaptability;
[0005] (3) The manufacturing cost of existing locknuts is relatively high, which greatly increases the cost of the entire equipment for places with large demand;
[0006] (4) It is inconvenient to assemble and use the existing locknut

Embodiment 1

[0051] Such as Figure 1-13 As shown, the liquid anti-loosening nut includes a nut cup sleeve 3 for holding a shear thickening liquid; a nut body 6 for blocking the shear thickening liquid is installed in the inner cavity of the nut cup sleeve 3; The outer casing of the nut body 6 and the nut cup sleeve 3 is provided with a locking structure 4 for preventing them from rotating; Shear thickens liquids. By adopting the above-mentioned liquid anti-loosening nut, the use of shear thickening liquid and the anti-loosening of the nut has the effect of permanent anti-loosening, and the above-mentioned anti-loosening nut has a simple structure, convenient processing and manufacturing, and low cost; in addition, its overall shape The size is small, it can be adapted to the location with limited installation space, and has strong adaptability; it is especially suitable for high-frequency vibration and strong impact occasions.

[0052] Further, the nut cup sleeve 3 adopts a first extern...

Embodiment 2

[0059] The method for assembling and using any one of the liquid locknuts includes the following steps:

[0060] Step1: Pass the screw 1 through the through holes of the components to be connected in sequence, and set the gasket 2 on the screw 1;

[0061] Step2: Put the nut cup sleeve 3 on the screw 1, and make the opening of the first internal thread segment 303 outward;

[0062] Step3: Place the shear thickening liquid inside the first internal thread section 303 of the nut cup sleeve 3;

[0063] Step4: Screw the nut body 6 onto the screw rod 1, and make the first threaded column 604 match the first internal thread segment 303;

[0064] Step5: Install the locking structure 4 on the outside of the nut cup sleeve 3 and the nut body 6, and fix them.

[0065] Working principle of the present invention is:

[0066] By adopting the characteristics of shear thickening liquid: it exists in the form of liquid in normal state, but once it is impacted and compressed, the shear thick...

Abstract

The invention discloses a liquid locknut and an assembling use method. The liquid locknut comprises a nut cup sleeve used for containing shear thickening fluid, a nut body used for blocking the shearthickening fluid is arranged in an inner cavity of the nut cup sleeve, the nut body and the nut cup sleeve are sleeved with a locking structure used for preventing the nut body and the nut cup sleevefrom rotating, and the shear thickening fluid is contained in a cavity formed through cooperation of the nut cup sleeve, the nut body and a screw. According to the liquid locknut, the shear thickeningfluid and the nut assembly are matched, bolt fixed connection is achieved, and the aim that a bolt and the nut are cooperated and are impacted or vibrated severely, loosening is prevented is achieved.

Description

technical field [0001] The invention relates to a method for assembling and using a liquid anti-loosening nut, belonging to the field of threaded connectors. Background technique [0002] In high-frequency vibration or impact equipment, it is necessary to use locknuts to connect and fasten. At present, most of the commonly used locknuts are mechanical locknuts, and the mechanical locknuts have the following defects during use: [0003] (1) When the mechanical anti-loosening nut is in use, only one side of the thread is always in contact with the threaded part of the mechanical anti-loosening nut. In this way, during the long-term high-frequency vibration operation, the nut still has the defect of loosening, and it cannot be permanently anti-loosening Purpose; [0004] (2) The existing lock nuts have complex structures and relatively large dimensions, which cannot meet the requirements for use in locations with limited installation space, and have poor adaptability; [000...
