Description
Technical field
The present invention relates to a kind of screw more particularly to a kind of stabilization screws based on joinery and its construction.
Background technique
Existing screw is usually applied in various firmwares, and existing normal screws are by a screw rod, a nut, a pad
Piece, a nut composition, in usual cases, when of less demanding for fastening situation, most of screw can be dealt in the market,
But in nowadays high-tech delicate fields, such as high-speed railway rail, train accessory, airplane spare parts, large bridge, large-scale gate dam neck
Domain, because safety requirements is higher in above-mentioned field, and part receives pressure and vibration is bigger than ordinary circumstance, therefore normal screws are not
It can be applied to above-mentioned field well.At present in actual conditions, the screw of rock-steady structure has that structure is complicated more, difficult to install
Situation, and still will appear fastening attenuation in use.
Summary of the invention
Goal of the invention: the present invention proposes a kind of stabilization screw based on joinery and its construction, can reduce in screw use process
Fastening attenuation, simplify installation difficulty, improve accessory stability and ease for operation in practical applications.
Technical solution: the technical scheme adopted by the invention is that a kind of screw, including screw body, nut, elastomeric pad
And nut, described screw body one end are provided with the first external screw thread, the other end is provided with the second external screw thread；First external screw thread
It is opposite with the second externally threaded hand of spiral；The nut is provided with the first internal thread hole compatible with the first external screw thread, institute
The one end for stating nut is provided with the second internal thread hole compatible with the second external screw thread；The elastomeric pad is arranged in nut and spiral shell
Between cap；It is provided with the first sawtooth on first external screw thread, is provided with the second sawtooth on first internal thread hole, described
One sawtooth and the second sawtooth complement each other to form joinery and its construction.
Preferably, the screw body further includes non-threaded section be arranged between the first external screw thread and the second external screw thread.
Preferably, the vertical interval of the adjacent thread of first external screw thread and first internal screw thread is H；Further
Preferably, vertical interval when first sawtooth and second sawtooth cooperate is H/2.
Preferably, the section of first sawtooth and second sawtooth is right angled triangle；It is further preferred that institute
The short length of straight flange for stating right angled triangle is H/2.
Preferably, first sawtooth is identical with the quantity of second sawtooth, and by the vertical interval of adjacent thread and
Radius of fillet determines.
Preferably, the elastomeric pad is the opening shape of inner circular, outer ring regular hexagon, it is further preferred that institute
The one end for stating elastomeric pad opening has a fixed angle of altitude, and the vertical range of apogee distance nut is greater than H/2.
The utility model has the advantages that the present invention can be improved the tightness of screw and nut, it is steady in engineer application to promote part
Qualitative and reliability；Easy to assembly quick, ease for operation is strong.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention；
Fig. 2 is the schematic cross-section of joinery and its construction of the invention.
Specific embodiment
Such as Fig. 1 and Fig. 2, a kind of stabilization screw based on joinery and its construction of the present invention, including screw body 1, nut
2, elastomeric pad 4 and nut 5, one end of screw body 1 are provided with the first external screw thread, and the second external screw thread, the two is arranged in the other end
Between be non-threaded section；First external screw thread is opposite with the second externally threaded hand of spiral, diameter is identical；Nut 2 is provided with and the
Compatible first internal thread hole of one external screw thread, one end of nut 5 are provided with the second internal screw thread compatible with the second external screw thread
Hole.Wherein the vertical range of the adjacent thread of the first external screw thread and the first internal screw thread is H, is provided with first on the first external screw thread
Sawtooth 6, is provided with the second sawtooth 7 on the first internal thread hole, and the quantity of both the first sawtooth 6 and second sawtooth 7 is by adjacent thread
Vertical interval H and radius of fillet determine, be consistent and complement each other to form joinery and its construction 3, the first sawtooth 6 and the second sawtooth
7 section is direct triangle, and short length of straight flange is H/2.Wherein elastomeric pad 4 is inner circular and outer ring regular hexagon
Opening shape, one end opening has a fixed angle of altitude, and the vertical range of highest point and nut 5 is greater than H/2, is placed on screw rod master
Non-threaded section of body 1, to guarantee that the first sawtooth 6 and the second sawtooth 7 just match after elastomeric pad 4 flattens, non-threaded section can
With preferably fixed elastomeric pad 4, while frictional resistance is smaller when pushing, convenient for the fastening of joinery and its construction 3.
Concrete operating principle: nut 2 being combined with first external screw thread of 1 one end of screw body and is covered on screw body 1,
And slide to the screw position of joinery and its construction 3, then by elastomeric pad 4 from another end cap on screw body 1, then by nut 5 with
Second external screw thread of 1 other end of screw body combines opposite direction and rotates and push elastomeric pad 4, while rotating nuts 2, until
The first sawtooth 6 on first external screw thread and the second sawtooth 7 on the first internal thread hole mutually coincide and form joinery and its construction 3, at this time
Elastomeric pad 4 moves the distance of H/2, and contact surface can generate frictional force between upper-lower section sawtooth, so that screw keeps locking
State can not loosen.When disassembly is desired, it will be lifted on elastomeric pad 4, active force is transferred on the first internal thread hole of nut 2
The second sawtooth 7, the contact surface interaction of joinery and its construction 3, makes active force between joinery and its construction 3 be greater than nut 2 at this time
Active force, the two mutually separate, and complete disassembly task.
