Abstract
A kind of fastener, including the first nut, the second nut, bolt, the bolt include thick portion and thin portion, and the thick portion diameter is more than thin portion, and the thick portion is opposite with thin portion thread rotary orientation；One end of the thick portion is fixedly connected with third nut, and the other end of thick portion is threaded with the second nut, the first nut is provided on second nut, and first nut is threadedly coupled with thin portion, and first nut is connected with the second nut.The purpose of this utility model is to provide a kind of fastener, can preferably play fastening effect.
Description
Technical field
The utility model belongs to mechanical articles for use, specially a kind of fastener.
Background technology
In existing fastener, a bolt and a fixing nut and a locking nut is usually used, then
Workpiece is fixed, existing bolt is usually integrally formed, is susceptible to stripped thread, if local stripped thread, due to being one
It is body formed just can only integral replacing, and use existing fixing nut and locking nut, needing railway to be mounted, bridge etc.
It is larger due to shaking using existing clamp device on heavy mechanical equipment, it is susceptible to nut loosening, equipment occurs in less serious case
Failure, severe one is it is possible that the accidents such as dangerous.
Utility model content
The purpose of this utility model is to provide a kind of fastener, can preferably play fastening effect.
In order to achieve the above object, the technical solution adopted in the utility model is：A kind of fastener, including the first nut, the
Two nuts, bolt, the bolt include thick portion and thin portion, and the thick portion diameter is more than thin portion, and the thick portion is revolved with thin portion screw thread
To opposite；One end of the thick portion is fixedly connected with third nut, and the other end of thick portion is threaded with the second nut, and described
The first nut is provided on two nuts, first nut is threadedly coupled with thin portion, and first nut is engaged with the second nut
Connection.
Further, the position that first nut and the second nut are in contact is zigzag, and is uneven.
Further, first nut is acorn nut.
Further, the second nut and the first nut are oppositely oriented.
The beneficial effects of the utility model：（1）The utility model is simple in structure, and operability is strong.Use the first nut for
Anti- silk, the second nut are positive silk, and using mutual cooperation, rugged zigzag structure, so that it is preferably fixed, prevent
Workpiece, equipment etc. shake.
（2）3 nuts are used above using a bolt in the utility model, a fixing nut, two locking nuts,
One positive silk, an anti-silk, and be mutually twisted, nut loosening caused by due to external force shakes can be offset.
（3）The utility model just needs machinery to be mounted, railway, installs this fixing piece on bridge, when fixing piece is shaken
When, forward leading nut and anti-silk nut are mutually twisted, and right system is moved on a left side, and left system is moved on the right side, to achieve the effect that prevent to loosen.

Fig. 1 is the utility model dimensional structure diagram.
Fig. 2 is second of view stereo structural schematic diagram of the utility model.
Fig. 3 is the utility model schematic front view.
Fig. 4 is the utility model nut structure diagram.
Label character described in figure is expressed as：1, the first nut；2, the second nut；3, bolt；30, thin portion；31, thick portion；
4, third nut.
Specific implementation mode
In order to enable those skilled in the art to better understand the technical solutions of the present invention, below in conjunction with the accompanying drawings to this reality
Be described in detail with novel, the description of this part be only it is exemplary and explanatory, should not be to the scope of protection of the utility model
There is any restriction effect.
As Figure 1-Figure 4, the concrete structure of the utility model is：A kind of clamp device, the first nut 1, the second nut
2, bolt 3, the bolt 3 includes thick portion 31 and thin portion 30, and 31 diameter of the thick portion is more than thin portion 30, the thick portion 31 and thin portion
30 thread rotary orientations are opposite；One end of the thick portion 31 is fixedly connected with third nut 4, and the other end of thick portion 31 is threaded with
Two nuts 2 are provided with the first nut 1 on second nut 2, and first nut 1 is threadedly coupled with thin portion 30, and described first
Nut 1 is connected with the second nut 2.
Preferably, the position that first nut, 1 and second nut 2 is in contact is zigzag, and presents and be uneven.
Preferably, first nut 1 is acorn nut.
Preferably, the second nut 2 and the first nut 1 are oppositely oriented.
Preferably, the second nut 2 is forward leading nut, and the first nut 1 is anti-silk nut, and 31 screw thread of the thick portion is positive silk,
30 screw thread of the thin portion is anti-silk.
When specifically used, bolt 3 passes through the workpiece for needing to fasten first, then the second nut of positive silk 2 is inserted in bolt 3, from
Thin portion 30 passes through, and screws in thick portion 31, tighten makes its workpiece fix to the right, loosens in order to prevent, then to the left by the first nut of anti-silk 1
It tightens.Its first nut 1 is set to be mutually twisted with the second nut 2, being allowed to left and right cannot all loosen, and perfectly create really forever
Gu effect.
It should be noted that herein, the terms "include", "comprise" or its any other variant are intended to non-row
His property includes, so that the process, method, article or equipment including a series of elements includes not only those elements, and
And further include other elements that are not explicitly listed, or further include for this process, method, article or equipment institute it is intrinsic
Element.
Specific case used herein is expounded the principles of the present invention and embodiment, above example
Illustrate the method and its core concept for being merely used to help understand the utility model.The above is only the preferred of the utility model
Embodiment, it is noted that due to the finiteness of literal expression, and objectively there is unlimited concrete structure, for this technology
For the those of ordinary skill in field, without departing from the principle of this utility model, several improvement, retouching can also be made
Or variation, above-mentioned technical characteristic can also be combined in the right way；These improve retouching, variation or combination, or not
It is improved that the design of utility model and technical solution are directly applied into other occasions, it is regarded as the protection of the utility model
Range.
