The top nut that stop nut sub-assembly 100 includes at least a middle nut 2 and is used cooperatively with middle nut 2
1 and a lower nut 3, the quantity of middle nut 2 increased according to actual needs, top nut 1 and the quantity of lower nut 3 are constant.
Nut 2 can carry out mutual cooperation connection by boss and groove in 3 kinds, so that the quantity of centering nut 2 carries out
Increase.
Top nut 1 is identical as the height of lower nut 3, and the height of middle nut 2 is at least 1.5 times of top nut 1.
A kind of assembling process of the stop nut sub-assembly of the present embodiment:
A kind of stop nut sub-assembly 100 of the present embodiment is being bolted in use, first tighten lower nut 3, then
Middle nut 2 is screwed onto and is bonded with lower nut 3, continues to tighten middle nut 2 later, middle 2 part of nut can according to actual needs next pair
The quantity that is screwed into of middle nut 2 is increased, and at this time under the action of groove, the boss face of middle nut 2 will generate flexible deformation,
To thread-rolling screw contact surface, increases frictional force and achieve the effect that locking, then top nut 1 is screwed into screw rod, repeats above-mentioned step
It is rapid to further enhance anti-loosing effect, complete the assembling of stop nut sub-assembly 100.
The action and effect of embodiment
A kind of stop nut sub-assembly according to involved in the present embodiment increases reality because having used combination nut
The number of threads of load is born, so, the non-uniform problem of the thread load occurred when avoiding using single nut.Therefore originally
A kind of stop nut sub-assembly of embodiment is easy for assembly, and anti-loosing effect is good, and has good applicability.
A kind of stop nut sub-assembly involved in the present embodiment, because each nut cooperate when tightening, on nut
Boss elastic deformation can occur under extrusion so that boss is shunk, to increase the frictional force of screw thread, so, reach
Locking effect is arrived.
A kind of stop nut sub-assembly involved in the present embodiment, because the middle nut of different structure being capable of phase there are three types of tools
It is mutually cooperatively connected, quantity superposition can be carried out according to actual needs to increase the length of entire stop nut sub-assembly by centering nut
Degree, so, there is good applicability.
Above embodiment is preferred case of the invention, the protection scope being not intended to limit the invention.
