Description
Technical field
The invention is related to mechanized equipment fastener areas, in particular to a kind of Anti-loose bolt combination.
Background technique
Assembling process of the mechanized equipment from part to complete machine be unable to do without the tight fit of fastener.Bolt fastener is application
Most commonly used a kind of fastener forms, in the links such as equipment transport and runs, due to external force such as vibrations
It influences, bolt fastener can make the frictional force between screw thread to be because of pressure pop-off between the thread that is mutually twisted
Zero, occur loosening to make to be threadedly coupled or even fall off, so that the normal performance for influencing equipment, which results even in equipment, occurs event
Barrier.Therefore, the technical issues of locking anticreep of bolt fastener is always this field practitioner's urgent need to resolve.
In order to be gained the initiative in market competition using technical advantage, in view of the above-mentioned problems, applicant organizational technology personnel
Research of technique is carried out, to solve the problems, such as that bolt fastener easily loosens.
Innovation and creation content
The technical issues of easily loosening for bolt fastener, the invention provide a kind of Anti-loose bolt combination, should
The technical solution of Anti-loose bolt combination is achieved in that
The Anti-loose bolt combination, including screw rod and nut further include anti-raise one's hat；
The annular chamber concentric with screw hole is offered on one end face of nut, edge in the threaded walls between annular chamber and screw hole
Screw hole is axially evenly equipped with several side ports, and side port is connected to annular chamber and screw hole；Anti- raise one's hat matches with the annular chamber on nut,
It can be placed in annular chamber, described to prevent raising one's hat including connector, connector side is fixedly installed elastomer, and anti-height of raising one's hat is greater than
Annular chamber depth, connector height are less than annular chamber depth.
Further, the indentation of indent is provided on the elastomer lateral wall along its circumferential direction.
Further, the annular chamber section is annular shape, correspondingly, anti-to raise one's hat as with the cylindric of perforation hollow cavity
Structure.
Further, the connector lateral wall, annular chamber on the inner sidewall of threaded walls far from being tapped with capable of being mutually matched
Screw thread.
Further, the connector other side is fixedly installed base station, and base station diameter is not less than nut diameter.
In actual use, the nut in the combination of this Anti-loose bolt is threaded on screw rod, and nut and anti-raise one's hat match, and will be prevented
It raises one's hat and is placed in the annular chamber on nut, go deep into anti-raise one's hat in annular chamber by external force, elastomer is deformed therewith, is led to
It crosses side port to enter in screw hole, the thread pitch between screw rod and threaded walls is filled and is stoppered, increase and be mutually twisted
Frictional force between thread, and elastic force possessed by elastomer itself can also play the role of the vibration of weakening solution, thus effectively
The disappearance for preventing frictional force between screw thread enhances screw-threaded coupling effect, solves the problems, such as that bolt fastener easily loosens.
As for the external force, the assembly combined with this Anti-loose bolt is related.For example, anticreep cap sleeve is first entered into screw rod,
And offset with by fastening object, then screw in nut until nut will be fastened by fastening object, during this, external force is by by fastener
The power that screws of part and nut provides jointly.

Specific embodiment
It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the invention can
To be combined with each other.
The present invention will be described in detail below with reference to the accompanying drawings and embodiments creates.
The combination of Anti-loose bolt described in the invention, as shown in Figure 1, 2, 3, including screw rod 1 and nut 2, further include
It is anti-to raise one's hat 3；
The annular chamber 5 concentric with screw hole 4, the screw thread between annular chamber 5 and screw hole 4 are offered on 2 one end face of nut
Several side ports 6 are axially evenly equipped with along screw hole 4 on wall 11, side port 6 is connected to annular chamber 5 and screw hole 4；It is described to prevent raising one's hat on 3 and nut 2
Annular chamber 5 match, can be placed in annular chamber 5, anti-raise one's hat 3 includes connector 8, and 8 side of connector is fixedly installed
Elastomer 9, for anti-3 height of raising one's hat greater than 5 depth of annular chamber, 8 height of connector is less than 5 depth of annular chamber.
In actual use, the nut 2 in the combination of this Anti-loose bolt is threaded on screw rod 1, and nut 2 and anti-raise one's hat 3 match,
Anti- will raise one's hat in the annular chamber 5 that 3 are placed on nut 2, and go deep into anti-raise one's hat 3 in annular chamber 5 by external force, elastomer 9 therewith by
It is squeezed and deformed, is entered in screw hole 4 by side port 6, the thread pitch between screw rod 1 and threaded walls 11 is filled and is stoppered,
The frictional force between the thread being mutually twisted is increased, and elastic force possessed by elastomer itself can also play the vibration of weakening solution
Effect enhance screw-threaded coupling effect to effectively prevent the disappearance of frictional force between screw thread, solve bolt fastener
The problem of easily loosening.
As for the external force, the assembly combined with this Anti-loose bolt is related.As shown in figure 4, be a kind of assembly method,
It anti-will first raise one's hat and 3 be inserted in screw rod 1, and offset with by fastening object, then screw in nut 2 until nut 2 will be fastened by fastening object,
During this, external force by being provided jointly by the power that screws of fastening object and nut 2.
In the combination of this Anti-loose bolt, it is convenient on 9 lateral wall of elastomer along the indentation 10 that its circumferential direction is provided with indent
Elastomer 9 be squeezed after towards deforming in screw hole 4.
In the combination of this Anti-loose bolt, 5 section of annular chamber is annular shape, correspondingly, anti-to raise one's hat 3 as in perforation
The cylindrical-shaped structure of cavity.Being tapped on 8 lateral wall of connector, inner sidewall of the annular chamber 5 far from threaded walls 11 can be mutual
The screw thread matched.Above structure, another assembly method of corresponding this Anti-loose bolt combination, as shown in figure 5, first revolving nut 2
In screw rod 1 to then anti-will raising one's hat with the position that is offseted by fastening object and 3 be inserted in screw rod 1 and screw in the annular chamber of nut 2
In 5, then screw on nut 2 will be fastened by fastening object.
In the combination of this Anti-loose bolt, 8 other side of connector is fixedly installed base station 7, and 7 diameter of base station is not less than spiral shell
Female 2 diameters.The setting of base station 7 is convenient for anti-3 carry out corresponding operation of raising one's hat.
In the combination of this Anti-loose bolt, base station 7 can also use elastomer gasket construction, when using assembly side shown in Fig. 4
When formula, anticreep effect can be further increased.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
