Description
Technical field
The present invention relates to technical field of fastening, it is specially a kind of be applied on train, in high-speed rail, on aircraft, on ship,
In the various equipment for having vibration and high vibration will not be from the screw column assembly of loose nut.
Background technique
The most common fastener of plain nut and screw column people the most in the market is mainly logical by nut and screw column
The occlusion of silk rolling tooth, but in occlusion, still had the gap between nut internal thread and the outer silk of screw column, and work as nut and screw column
Between the object fixed when transmitting vibration, nut can be loosened with screw column, be will cause object shakiness and collapsed, it is possible to
Cause very serious economic loss and safety accident.In the market common nut with when screw column fixed object in order not to can shake
Dynamic, worker can add again nut and spring washer on nut, and when stress reaches pancake, spring mattress just loses spring mattress
Remove elastic force.It is seamless that the nut reinforced again on nut can not also allow nut internal thread to be held tightly with screw column, works as object vibration
When, nut still can loosen.
Based on this, the present invention devises one kind will not be from the screw column assembly of loose nut, to solve the above problems.
Summary of the invention
The purpose of the present invention is to provide one kind in fixed object, the tightening of more chains of rings of use, locked, expansion, lock
Extremely, it expands, is locked, avoiding economic loss, improve safety guarantee will not be from the screw column assembly of loose nut, to solve
The problems mentioned above in the background art.
To achieve the above object, the invention provides the following technical scheme: it is a kind of will not from the screw column assembly of loose nut,
Including screw column, the first nut, the second nut, third nut and screw rod, one end of the screw column is equipped with integrally formed
Screw column turret head, the other end inside of screw column are equipped with screw column inner conical silk, and the outer wall of the screw column is equipped with screw
The outer silk of column, the inside of first nut are provided with wire hole in the first nut, and first nut passes through wire hole set in the first nut
One end on the outside of screw column, the outer wall of first nut far from screw column turret head is equipped with the first nut male-tapered
Silk, the inside of second nut are provided with the second nut inner conical wire hole, and second nut passes through the second nut inner conical silk
Hole passes through the outside of screw column, covers on the first nut male-tapered silk, the inside of the third nut is provided with third nut internal thread
Hole, the third nut are covered on screw column by wire hole in third nut, far from screw column on the outer wall of the third nut
One end of inner conical silk is equipped with third nut male-tapered silk, and wire hole is far from spiral shell in the third nut male-tapered silk and the first nut
One end of silk column turret head is mutually engaged, and one end of the screw rod is mutually engaged with the inside of screw column inner conical silk.
Preferably, the inside of first nut is equipped with the first expansion groove far from one end of screw column turret head.
Preferably, first nut is constantly engaged by the second nut inner conical wire hole with the first nut male-tapered silk,
Gradually taper up the first expansion groove, wire hole gradually tapering up by the first expansion groove in first nut, with screw column
Outer silk occlusion is held tightly.
Preferably, the third nut is constantly engaged by wire hole in third nut with the outer silk of screw column, the third spiral shell
Female male-tapered silk is constantly mutually engaged with the one end of wire hole far from screw column turret head in the first nut, and the first expansion groove leans on
One end of nearly third nut male-tapered silk expands, so that third nut male-tapered silk is close to the one of third nut male-tapered silk
Diameter is held to be greater than the second nut inner conical wire hole close to the internal diameter of third nut male-tapered silk.
Preferably, the inside of the screw column inner conical silk is provided with the second expansion groove far from one end of screw rod.
Preferably, the screw rod is constantly engaged with screw column inner conical silk, so that the second expansion groove expansion, the spiral shell
The outer silk expansion of the screw column of the silk column other end is greater than the internal diameter of third nut internal thread.
Preferably, the first nut male-tapered silk, the second nut inner conical wire hole and third nut male-tapered silk cone
The tilt angle on shape inclined-plane is 5 ° -15 °.
Compared with prior art, the beneficial effects of the present invention are: structure of the invention is novel in design, pass through multiple tracks expansion, lock
Extremely, reach the physical effect that nut oneself will not loosen, and when the object fixed transmits vibration force, the vibration that object transmits
Power passes through the expanded screw column one end of the first nut, the second nut, third nut, screw rod successively vibration damping, passes through physics
After the vibration damping of effect, one end that the vibration force of third nut can not make vibration force that third nut is expanded by screw column is passed to
Loosen and fall off, thus reach will not from loose nut only if it were not for artificial loosen when, the effect that oneself can not be loosened, avoid because
Later period fails the accident that equipment maintenance is occurred in time, so as to avoid economic loss, improves safety guarantee, this hair
It is bright to can be used on train from loose nut, in high-speed rail, on aircraft, on ship, in the various equipment for having vibration and high vibration.

Fig. 1-5 is please referred to, the present invention provides a kind of technical solution: a kind of to wrap from the screw column assembly of loose nut
Screw column 2, the first nut 4, the second nut 8, third nut 10 and screw rod 15 are included, one end of the screw column 2 is equipped with one
The other end inside of molding screw column turret head 1, screw column 2 is equipped with screw column inner conical silk 13, the outer wall of the screw column 2
It is equipped with the outer silk 3 of screw column, the inside of first nut 4 is provided with wire hole 5 in the first nut, and first nut 4 passes through the
5 sets of the wire hole outsides in screw column 2 in one nut, one end on the outer wall of first nut 4 far from screw column turret head 1 are set
There is the first nut male-tapered silk 6, the inside of second nut 8 is provided with the second nut inner conical wire hole 9, second nut 8
The outside that screw column 2 is passed through by the second nut inner conical wire hole 9, covers on the first nut male-tapered silk 6, the third nut
10 inside is provided with wire hole 12 in third nut, the third nut 10 by 12 sets of wire hole in third nut on screw column 2,
One end on the outer wall of the third nut 10 far from screw column inner conical silk 13 is equipped with third nut male-tapered silk 11, and described the
Three nut male-tapered silks 11 are mutually engaged with the one end of wire hole 5 far from screw column turret head 1 in the first nut, the screw rod 15
One end is mutually engaged with the inside of screw column inner conical silk 13.
Wherein, the inside of first nut 4 is equipped with the first expansion groove 7 far from one end of screw column turret head 1, described
First nut 4 is constantly engaged by the second nut inner conical wire hole 9 with the first nut male-tapered silk 6, make the first expansion groove 7 by
Contracting is tapered, the gradually tapering up by the first expansion groove 7 of wire hole 5, is engaged holding with silk 3 outside screw column in first nut,
Reaching the first nut 4 will not loosen.
The third nut 10 is constantly engaged by wire hole 12 in third nut with the outer silk 3 of screw column, the third nut
Male-tapered silk 11 is constantly mutually engaged with the one end of wire hole 5 far from screw column turret head 1 in the first nut, the first expansion groove
7 expand close to one end of third nut male-tapered silk 11, so that third nut male-tapered silk 6 is close to third nut male-tapered
One end diameter of silk 11 is greater than the second nut inner conical wire hole 9 close to the internal diameter of third nut male-tapered silk 11, reaches the second spiral shell
Mother 9 sting it is next can not move back silk, to will not loosen.
Wherein, the inside of the screw column inner conical silk 13 is provided with the second expansion groove 14 far from one end of screw rod 15,
