Preferably, the number of the air grooves is consistent with the number of the elastic sucking discs in a one-to-one correspondence manner.
By adopting the scheme, each air groove is independently arranged, so that the inside of the elastic sucking discs are not communicated with each other, if radian or uneven parts exist on the surface of an object to be locked, the adsorption of the nut can be realized by only needing more than one elastic sucking disc to be fully relieved from the surface of the object to be locked, and the adsorption probability is increased.
Preferably, one end of the elastic plug close to the air groove is arranged in a frustum shape with the tip outwards.
By adopting the scheme, the frustum-shaped design is convenient for the elastic blocking to be led into the air groove, and is convenient for the installation of the elastic blocking.
Preferably, the elastic plug is synchronously fixed on a mounting ring.
By adopting the scheme, the elastic plugs are all arranged on the mounting ring, and all the elastic plugs can be synchronously taken down by pulling the mounting ring, so that the desorption speed is improved.
Preferably, the elastic sucker is synchronously fixed on an elastic ring, the elastic ring is fixed on one side of the nut body, and the elastic ring is provided with vent holes respectively communicated with the air groove and the elastic sucker.
By adopting the scheme, the elastic sucker is arranged on the elastic ring, so that on one hand, the installation is convenient, on the other hand, the friction force and the buffering performance can be increased, the locking stability of the nut is improved, and the loosening probability of the nut is reduced.
A second object of the present utility model is to provide a fastening assembly comprising a bolt on which the said suction nut is arranged.
By adopting the scheme, after the adsorption type nut is provided with the bolt, the adsorption type nut can be adsorbed and fixed with the surface of an object to be locked due to the adsorption performance of the adsorption type nut, so that the locking can be realized by screwing the bolt by using a tool, the operation is convenient, and the scratch on the surface of a workpiece can be avoided.
The utility model has the remarkable technical effects due to the adoption of the technical scheme: set up elastic suction cup in nut body one side, elastic suction cup both can utilize its adsorption performance to adsorb on the surface of waiting to lock the object, can utilize elastic material's frictional resistance to increase nut body pivoted degree of difficulty again, can directly adsorb on waiting to lock the object, need not to carry out spacingly with the help of the instrument, can directly cooperate with the bolt, realize locking through rotating the bolt, and this nut body can not damage waiting to lock the object and can also play the effect of preventing the pine.
