Description
Technical Field
The utility model belongs to the technical field of lock nut, specifically indicate a locking self-locking nut.
Background
The general nut can be loosened by itself due to vibration and other reasons in the using process, and in order to prevent the phenomenon, the self-locking nut is invented. The self-locking nut has the functions of anti-loosening and anti-vibration. The working principle is generally self-locking by friction force. The self-locking nut is classified according to functions and comprises a nylon ring embedded, a neck-closing device and a metal anti-loosening device. They all belong to the effective torque type locknuts. The self-locking nut is generally based on friction force, the principle is that the self-locking nut is pressed into a preset hole of a metal plate through embossing teeth, and the aperture of the general square preset hole is slightly smaller than that of a pressure riveting nut. The ruler is connected with the locking mechanism by using the nut, when the nut is screwed down, the ruler body is locked by the locking mechanism, and the ruler frame cannot move freely, so that the aim of locking is fulfilled; when the nut is loosened, the locking mechanism is disengaged from the ruler body, and the ruler frame moves along the ruler body. The anti-vibration anti-loosening performance of the anti-vibration anti-loosening device is greatly higher than that of other anti-loosening devices, and the vibration service life is several times or even dozens of times longer.
However, the torque force and the strength of the existing nylon self-locking nut are inferior to those of a common metal nut, the possibility of sliding teeth or head fracture exists when the torque force is too large, and in the long-time use process, due to the use environment of the nylon nut and the long-time friction force, the nylon ring of the nylon nut is easy to deform, so that the error of the nylon self-locking nut is large, and the service life of the nylon self-locking nut is influenced.
Disclosure of Invention
In order to solve the existing difficult problem, the utility model provides a locking self-locking nut which has the advantages of dual self-locking function, large locking strength, long service life, corrosion resistance, good heat-insulating property and light texture.
The utility model adopts the technical scheme as follows: the utility model provides a locking self-locking nut, includes nut main part, expanding spring, nut semi-ring holder and bolt, the inside of nut main part is equipped with the nut cavity, the interpolation of nut cavity is equipped with the bolt, install a pair of nut semi-ring holder in the nut cavity, nut semi-ring holder includes the nut semi-ring body, be connected with expanding spring between nut semi-ring body and the nut main part, spacing slider is installed to the both sides of nut semi-ring body, and is a pair of be equipped with the screw thread on the relative one side of nut semi-ring body, the inside chisel of nut main part have with spacing slider assorted spout.
Furthermore, the nut main body is made of 304 stainless steel, so that the corrosion resistance of the self-locking nut can be improved.
Further, nut main part one side is for inserting the mouth, the nut opposite side is the flange face, the use of easy auto-lock nut, install the nylon circle in the nut main part access mouth, the nylon circle can play the effect of a heavy auto-lock.
Furthermore, the end of the nut semi-ring body close to the access opening is chamfered, so that the self-locking nut is easily inserted into the bolt.
Furthermore, the maximum sliding diameter of the nut half-ring bodies is equal to the diameter of the nut main body access opening, and the nut half-ring bodies can clamp the bolt to play a role of double self-locking.
After the structure is adopted, the utility model discloses beneficial effect as follows: this scheme locking self-locking nut has dual self-locking function, and it when the nylon circle lost the effect, a pair of nut semi-ring body utilized expanding spring's elasticity can play the purpose of auto-lock, and it is 304 stainless steel matter simultaneously, and corrosion resistance is strong, can prolong self-locking nut's life, through with expanding spring connect again between nut main part and the nut semi-ring body can play thermal-insulated effect, the texture is also lighter.
