The first noumenon portion 10, outside cylinder portion 15 and varying diameter portion 13 are internally provided with the first threaded hole 11 that specification is identical and communicates,
Internal screw thread in threaded hole 11 can be full thread, but be not limited to full thread, it is only necessary to guarantee to meet the screw thread that locking needs
Length, the outer surface in the outside cylinder portion 15 circumferentially offer the first protrusion 14 continuously or discontinuously.Described first
The outer surface of nut 1 is provided with twisting structure 17, and twisting structure 17 can be hexagon formula, hexagon formula is not limited to, as long as energy
Realize twisting effect.
Specifically, the first threaded hole in bottom and varying diameter portion 13 is provided in the axial direction in the outer surface of the varying diameter portion 13
11 grooves 12 being connected, and the axial direction along the first nut 1 of groove 12 opens up, and the bottom of 12 axial direction of groove is round and smooth mistake
It crosses, when the quantity of groove 12 is multiple, several grooves 12 are uniformly distributed in varying diameter portion 13.The varying diameter portion 13 is diameter
Along the first nut 1 to the gradually smaller rotary structure in direction of the second nut 2, such as taper but it is not limited to taper.
Second nut 2 includes the second body part 26, is provided with and the first threaded hole in second body part 26
11 specifications are identical and the second threaded hole 22 for communicating with the first threaded hole 11, second body part 26 and the first nut 1 cooperate
One end be disposed with variable diameter hole 23, cylindrical hole 24, the variable diameter hole 23 is engaged with varying diameter portion 13, the cylindrical hole 24
It is engaged with outside cylinder portion 15, it is convex that the inner surface of the cylindrical hole 24 is provided with corresponding with the first 14 positions of protrusion second
Play 25, second protrusion 25 is along the inner surface of cylindrical hole 24 is circumferentially continuous or discontinuous setting.The appearance of second nut 2
Face is provided with twisting structure 21, and twisting structure 21 can be hexagon formula, is not limited to hexagon formula, as long as being able to achieve twisting work
With.
Specifically, variable diameter hole 23 is not limited to taper, as long as can realize that 1 variable-diameter structure of cross-notching nut is squeezed and deformed effect
Structure.
First protrusion 14 can for along outside cylinder portion 15 the circumferentially continuous setting in outer surface, as one whole section of circumference,
2 sections or 2 sections or more can also be divided into, and be circumferentially uniformly distributed setting along the outer surface in outside cylinder portion 24.When the first protrusion 14 is along outer
When the circumferentially continuous setting in the outer surface of cylindrical portion 15, second protrusion 25 is 2 sections or 2 sections or more, and along cylindrical hole 24
Surface is circumferentially uniformly distributed.When the first protrusion 14 is arranged for multistage, inner surface week of second protrusion 25 along cylindrical hole 24
To continuous setting, as one whole section of circumference.
The present invention illustratively gives three kinds of various forms of combination nuts, and Fig. 1-5 is the combination nut of form one, the
The varying diameter portion 13 of one nut 1 is taper revolving body, and the inner surface in the variable diameter hole 23 of the second nut 2 is to turn round mates with taper
Bellmouth.
Fig. 6-7 is the combination nut of form two, and the varying diameter portion 13 of the first nut 1 is arc revolving body, longitudinal section be
Arc, the inner surface in the variable diameter hole 23 of the second nut 2 are the arcuate socket that mates are turned round with arc.
Fig. 8-9 is the combination nut of form three, and the varying diameter portion 13 of the first nut 1 is step-like revolving body, longitudinal section
In step-like, the inner surface in the variable diameter hole 23 of the second nut 2 is and the arcuate socket of step-like revolution mates.
The installation process of combination nut of the invention are as follows:
