Description
Technical field
The present invention relates to a kind of anti-skidding antivibration bolt kits, belong to technical field of fastening.
Background technique
Nowhere carry out fixed object without using bolt and nut in daily life, as long as some facilities and equipments fasten, but
Some facilities and equipments, which both need to fasten, guarantees never becoming loose again.On the facilities such as track for a train, bridge, train, automobile,
Some equipment works long hours under the high-frequency of up to a hundred, thousands of HZ, and the bolt kit for fastening can loosen, even nut
It falls or screw rod is cut, cause safety accident.
Meanwhile existing anti-skidding antivibration bolt, nut, its structure is complicated, high production cost, and vibrationproof, anti-loosing effect are undesirable.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of anti-skidding antivibration bolt kits, can not only reach locking
The purpose of locking, and it is reusable.
To achieve the goals above, the technical scheme is that a kind of anti-skidding antivibration bolt kit, including bolt head,
Screw rod, nut shim and nut.Bolt head is fixedly connected with screw rod, and nut internal screw thread matches with screw flight, nut shim
Through-hole internal diameter is consistent with screw diameter, which is characterized in that the bolt end surface of the screw rod side is helicoid, and the hand of spiral
It is opposite with the hand of spiral of screw flight；The lower end surface of nut shim is helicoid, and is coincide with the helicoid of bolt end surface,
Upper surface is plane；The upper and lower end face of nut is helicoid, and is coincide with the helicoid of bolt end surface.
Preferably, the helicoid is right helicoid, rotation spiral surface screw pitch is 2 times of screw flight screw pitch.
Further, nut shim internal screw thread matches with screw flight.
The rotation spiral surface relative combinations of bolt head and nut shim, nut shim and spiral shell and two groups of nut shims use, can
Realize fastening fine adjustment function.In securing objects, the end face of out-of-flatness will make to generate between screw flight and internal screw thread uneven
Even fastening force can effectively prevent the spinning problem of plain bolt, nut.
Compared with the prior art, the advantages of the present invention are as follows: the present invention is generated not by fastening fine tuning, helicoid fastening
Symmetrical pretightning force effectively prevent the spinning problem of common screw, nut.Anti-loosening locking effect of the present invention is good, and structure letter
Single, manufacturing cost is low, is convenient for mass production.Product is not only easy to assembly, and to after using bolt and nut do not make
At any damage, bolt and nut still can be continued to use, save the cost.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2,3,4,5 use schematic diagram for of the invention；
Description of symbols: 1- bolt head, 2- screw rod, 3- nut shim, 4- nut, 11- bolt end surface, 20- screw flight,

Specific embodiment
To make the objectives, technical solutions, and advantages of the present invention clearer, with reference to the accompanying drawings and examples to this hair
It is bright to be described in further detail.
As shown in Figure 1, this anti-skidding antivibration bolt kit, includes bolt head 1, screw rod 2, nut shim 3 and nut 4, bolt head 1
It is fixedly connected with screw rod 2, nut internal screw thread 40 matches with screw flight 20, nut shim through-hole internal diameter and screw diameter one
It causes.The bolt end surface 11 of 2 side of screw rod is helicoid, and the hand of spiral is opposite with the hand of spiral of screw flight 20；
The lower end surface 31 of nut shim 3 is helicoid, and is coincide with the helicoid of bolt end surface 11, and upper surface is plane；Nut 4
Upper and lower end face 41 is helicoid, and is coincide with the helicoid of bolt end surface 11.When i.e. screw flight 20 is right-handed thread, bolt
End surface 11, nut shim lower end surface 31, nut upper and lower end face 41 are left hand helix face.
Each helicoid is left-handed right helicoid, and rotation angle is 360 °, and each helicoid parameter is consistent, the spiral shell of helicoid
Away from being 2 times of 20 screw pitch of screw flight, multiplying power can also be adjusted according to by actual needs such as securing objects, screw diameters.
The nut shim internal screw thread 30 matches with screw flight 20.
Similarly, if screw flight 21 on screw rod 2 is left hand thread, bolt end surface 11, nut shim lower end surface 31,
Nut upper and lower end face 41 is dextrorotation right helicoid.
As shown in Fig. 2, with tool anchor stud head 1, applying on nut shim 3 in the case where screw rod 2 fastens substantially
External force makes to be located remotely from each other between the spiral vertex of surface of bolt end surface 11 and the spiral vertex of surface of nut shim lower end surface 31, carefully
Fine adjustment fastens dynamics, and nut shim internal screw thread 30 is made to coincide tighter with screw flight 20 is made.
As described in Figure 3, rotation spiral surface top and body surface pressure in the case where screw rod 2 gradually fastens, in bolt head 1
It is continuously increased, so that screw flight 20 be made more to become smaller with by the internal screw thread gap of fastening object, coincide tighter, to reach
It prevents spin then loosens.
As described in Figure 4, in the case that nut 4 gradually fasten when using common screw, the rotation spiral surface top of nut 4 and
Body surface pressure is continuously increased, so that screw flight 20 be made more to become smaller with 40 gap of nut internal screw thread, coincide tighter.Tightly
Gu during, screw rod two sides are acted on by asymmetric fastening force, to further effectively prevent spin then loosen.
As described in Fig. 5, in the case where fastening substantially using nut shim 3, nut 4 and plain bolt, spiral shell is fixed with tool
Cap 4 applies external force on nut shim 3, makes the spiral vertex of surface of nut lower end surface 11 and the spiral of nut shim lower end surface 31
It is located remotely from each other between vertex of surface, fine adjustments fasten dynamics, so that reaching prevents spin then loosen.
In practical applications, screw flight 20 can be identical with the direction of rotation of each helicoid；It can not inside nut shim 3
Internal screw thread is set；Anti-slop serrations etc. can also be set in each helicoid apical position of bolt head 1, nut shim 3, nut 4, into one
Step control spinning problem.
