By using above-mentioned technical proposal, unidirectional helical teeth and non-return helical teeth are equipped with so that jam nut is only single To screw operation, and the loosening that can not circle round, axis usually can all grow one end after screwing into nut, and the time can cause after too long It gets rusty, one end of nut body is provided with upper shield, the short vessel and long vessel in upper shield communicate, and can be used to accommodating axis and expose spiral shell The lower end of the part of cap, short vessel is provided with screw thread, and energy fixing axle exposes the part of nut, rubber is internally provided in upper shield Layer, after axis precession nut, one end of axis is by the rubber layer top jail in upper shield, and frictional force increases, and anti-loosing effect is carried significantly Height, annular gasket are connected by way of engagement with nut, are avoided that the unexpected of gasket is lost, after tightening, while can also be saved The time of appropriate spacers is individually found, fastening card is arranged in annular gasket, and axis limits annular gasket rotation, annular gasket limitation Axis convolution loosens, and axis once screws, can not just loosen and remove again, to realize the effect of anti-loose anti-theft.
As preferred:The inner wall of the short vessel is equipped with anti-slop serrations.
By using above-mentioned technical proposal, the effect of locking fastening is played.
As preferred:The anti-slop serrations are made of elastic deformation material.
As preferred:The shape of the fastening card is rounded.
By using above-mentioned technical proposal, according to the design of the internal diameter of annular gasket, convenient for the installation of fastening card.
As preferred:The unidirectional helical teeth and the engagement of non-return helical teeth, and can only towards the positive direction or rotate backward.
As preferred:The upper shield is detachable.
By using above-mentioned technical proposal, it can select suitable upper shield according to the difference of axle gauge lattice, be also easily accessible for service simultaneously Each installation.
The utility model has the advantage of:Structure design advantages of simple, the setting of the screw can enhance the locking effect of screw Fruit avoids loosened screw, improves safety.
