The minimum screw used；The general screw of TV, electric product, musical instrument, furniture etc.；It is then used as engineering, building, bridge
Large-scale screw, nut；Traffic tool, aircraft, electric car, automobile etc. are then used in combination for big primary screw.Current screw usually only one
The screw rod of a cylinder, can only attaching nut connect the identical threaded hole of two sizes, there is certain limitation.
Utility model content
In view of the deficiency of background technique, the technical problem to be solved by the utility model is to provide that can connect, two differences are big
The screw and nut assembly of the using flexible of small threaded hole.
To realize the above-mentioned technical purpose, the utility model provides following technical solution:
Screw and nut assembly, it is characterised in that: including screw rod, screw bolt and nut, the screw rod has cylindrical portion, the circle
Canister portion has the first external screw thread, and the peripheral wall bottom end of the cylindrical portion is inwardly connected with circular bottom part, and the circular bottom part is equipped with logical
Hole, the bolt have nut and threaded rod, and the threaded rod is equipped with the second external screw thread, and the threaded rod may pass through described logical
Hole is simultaneously moved, and the path length of the nut is greater than the internal diameter of the through-hole and is less than the internal diameter of the cylindrical portion, the nut
For hexagonal prisms structure, and the nut is equipped with the threaded hole that section be convex character shape, and the cylindrical portion and the threaded rod can one
On be once threaded on the threaded hole.
The threaded rod is cylinder, and the outer diameter of the threaded rod is equal to the internal diameter of the through-hole.
The inner wall of the through-hole is smooth wall.
The threaded hole is made of coaxial setting up and down and the first threaded hole communicated and the second threaded hole, first spiral shell
The inner wall of pit is equipped with the first internal screw thread to match with first external screw thread, and the inner wall of second threaded hole is equipped with and institute
State the second threaded hole that the second external screw thread of threaded rod matches.
The inner wall of the cylindrical portion is equipped with third internal screw thread.
Several gaskets are removably arranged on the threaded rod.
After the above technical solution is adopted, the beneficial effects of the utility model are: utilizing screw rod, the combination knot of screw bolt and nut
Two different size of threaded holes can be threaded togather by structure, overcome in the past can only threaded hole to equivalent diameter into
The problem of row connection, using flexible is easy to assembly.
Detailed description of the invention
The utility model has following attached drawing:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the bolt of the utility model is set in the sectional view in the screw rod；
Fig. 3 is the sectional view of the nut of the utility model；
Fig. 4 is the top view of the nut of the utility model.
Specific embodiment
As shown in Figure 1, screw and nut assembly, including screw rod 1, bolt 2 and nut 3, the screw rod 1 have cylindrical portion 11,
The cylindrical portion 11 has the first external screw thread, and the peripheral wall bottom end of the cylindrical portion 11 is inwardly connected with circular bottom part 12, the ring
Shape bottom 12 is equipped with through-hole, and the bolt 2 has nut 21 and threaded rod 22, and the threaded rod 22 is equipped with the second external screw thread,
The threaded rod 22 may pass through the through-hole and move up and down, and the path length of the nut 21 is greater than the internal diameter of the through-hole simultaneously
Less than the internal diameter of the cylindrical portion 11, to guarantee that nut can not pass through through-hole；The nut 3 is hexagonal prisms structure, and the spiral shell
Mother 3 is equipped with the threaded hole that section is convex character shape, and the cylindrical portion 11 and the threaded rod 22 can be threaded in one on the other
On the threaded hole, specific connection structure are as follows: the threaded hole is by the first threaded hole 31 that is coaxial setting up and down and communicating and the
Two threaded holes 32 composition, the inner wall of first threaded hole 31 are equipped with the first internal screw thread to match with first external screw thread,
The inner wall of second threaded hole 32 is equipped with the second threaded hole to match with the second external screw thread of the threaded rod 22.It uses
When, the threaded rod 22 of bolt 2 is first aligned to the through-hole for penetrating screw rod 1, threaded rod 22 is then made to pass through the first threaded hole of nut 3
31 and be aligned the second threaded hole 32 be threadedly coupled, with the rotation of threaded rod 22, cylindrical portion 11 will move closer to nut 3 simultaneously
It is final to screw in the second threaded hole 32, it is finally reached and screw rod 1, bolt 2 is closely tightened on nut 3 jointly and form component
Purpose in this way, which the component not only can connect different size of threaded hole, but also can be used alone screw rod 1 or spiral shell therein
Silk 2 has stronger flexibility.
The threaded rod 22 is cylinder, and the outer diameter of the threaded rod 22 is equal to the internal diameter of the through-hole, the through-hole
Inner wall is smooth wall.This structure can make threaded rod 22 just by through-hole, and loosen after preventing the two from connecting, and guarantee
Close-connected effect.
The inner wall of the cylindrical portion 11 is equipped with third internal screw thread.The function of screw rod 1 is further enhanced in this way, so that screw rod
1 can be attached by the first external screw thread and is threaded on other connectors by third internal screw thread, be had double
Reconnect effect.
Several gaskets 4 are removably arranged on the threaded rod 22.Gasket 4 can not only increase nut 21 and annular bottom
Frictional force between portion 12 may further be used to the length for adjusting exposed threaded rod 22, to adapt to the connecting hole of different depth, into
The switching performance of one step raising product.
It to sum up, can be by two different size of threaded hole screw threads using the composite structure of screw rod 1, bolt 2 and nut 3
It links together, overcomes the problems, such as in the past to be attached the threaded hole of equivalent diameter, using flexible is easy to assembly.
