Description
Technical field
The present invention relates to spacer for bolt field, and in particular to a kind of spacer for bolt for preventing from loosening.
Background technology
The main function of spiral shell pad is to prevent loosened screw, and the existing generally planar structure of spiral shell pad, when in use outside
Power effect is lower easily to be loosened, currently in order to avoiding spiral shell pad from loosening, sets a circle raised generally on inner ring, due to crowning
Width be less than the width of inner ring, when in use, when application is the machine with vibrations, or outdoor support, billboard
Deng easily shaking under external force, cause spiral shell pad and screw to occur relative motion, lower screw, which is used for a long time, can occur pine
It is dynamic.
The content of the invention
For defect present in prior art, it is an object of the invention to provide a kind of spacer for bolt for preventing from loosening,
It can be used in spiral shell pad and the occasion of relative motion occur with screw, and the lower screw of long-term use can keep preferable tightness.
To achieve the above objectives, the present invention is adopted the technical scheme that：
A kind of spacer for bolt for preventing from loosening, including upper gasket and lower gasket, the internal diameter of the upper gasket are more than
The external diameter of lower gasket, the upper gasket and lower gasket are connected by a tapered connection, and the tapered connection is with
Angle between portion's pad is 15 °~45 °；
Some projections are provided with the top and bottom of the upper gasket, lower gasket, and the upper gasket includes
Edge and the first outer in first, the projection are inclined in first between edge and the first outer, and the projection and first
Angle between interior edge is 15 °~30 °；
The lower gasket includes edge and the second outer in second, and the projection is inclined in second outside edge and second
Between, and described raised and the second interior angle between is 15 °~30 °.
On the basis of above-mentioned technical proposal, the raised vertical section rectangular triangle or trapezoidal.
On the basis of above-mentioned technical proposal, the raised angle of inclination is 15 °.
On the basis of above-mentioned technical proposal, the angle between the tapered connection and lower gasket is 20 °~40 °.
On the basis of above-mentioned technical proposal, the angle between the tapered connection and lower gasket is 30 °.
On the basis of above-mentioned technical proposal, the distance of upper gasket and lower gasket is 1~150mm.
On the basis of above-mentioned technical proposal, the distance of the upper gasket and lower gasket is 10mm.
On the basis of above-mentioned technical proposal, the distance between edge and the first outer are 0~150mm in described first.
On the basis of above-mentioned technical proposal, the distance between edge and the second outer are 0~150mm in described second.
On the basis of above-mentioned technical proposal, the inner side and outer side of the tapered connection is provided with projection.
Compared with prior art, the advantage of the invention is that：
(1) a kind of spacer for bolt for preventing from loosening of the invention, upper gasket, lower gasket distribution and screw and nut phase
Support, during screw and nut are tightened, tapered connection can act power, the contact surface of screw and nut occurs
The effect of resist force, when the effect of the external force such as vibrations occurs in use for screw, the resist force of tapered connection can be supported
The effect for the external force that disappears, it is to avoid spacer for bolt is relatively moved with screw, nut.
Meanwhile, the tip at the top of bulge-structure can produce frictional force, the direction of frictional force with screw, the nut being in contact
Relative movement with screw, nut is in opposite direction, it is to avoid nut loosens.
Brief description of the drawings
Fig. 1 be the embodiment of the present invention in prevent loosen spacer for bolt structural representation.
In figure：Edge in edge in 1- upper gaskets, 11- first, the outers of 12- first, 2- lower gaskets, 21- second, 22-
Two outers, 3- tapered connections, 4- is raised.
Embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 1, the embodiment of the present invention provides a kind of spacer for bolt for preventing from loosening, including upper gasket 1 is with
Portion's pad 2, the internal diameter of upper gasket 1 is more than the external diameter of lower gasket 2, and upper gasket 1 and lower gasket 2 pass through a taper connection
Part 3 is connected, and the angle between tapered connection 3 and lower gasket 2 is 15 °~45 °.Upper gasket 1, lower gasket 2 and taper
Connector 3 is made of flexible member, and in actual fabrication process, upper gasket 1, lower gasket 2 and tapered connection 3
It is integrally formed, and is connected between upper gasket 1 and tapered connection 3 by arc angling, lower gasket 2 and tapered connection 3
Between connected by arc angling, it is to avoid right angle connection cause easily occur bending in addition fracture.And pad can be with one individually
Use, multiple can also join end to end and use.
In actual production, the angle between tapered connection 3 and lower gasket 2, this implementation can be arranged as required to
In example, the angle between tapered connection 3 and lower gasket 2 is 20 °~40 °, between tapered connection 3 and lower gasket 2
Optimal angle is 30 °.
Upper gasket 1, the top and bottom of lower gasket 2 are provided with some raised 4, the inside of tapered connection 3 and
Outside is provided with some raised 4, and upper gasket 1 is included along 11 and first outer 12 in first, and projection 4 is inclined at the
In one along 11 and first between outer 12, and it is 15 °~30 ° along the angle between 11 in projection 4 and first；Lower gasket 2 is wrapped
Include along 21 and second outer 22 in second, projection 4 is inclined in second along 21 and second between outer 22, and projection 4 with
Along the angle between 11 it is 15 °~30 ° in second.Raised 4 angle of inclination in upper gasket 1 and lower gasket 2 is according to reality
Border needs to set, in the present embodiment, and the angle of inclination of projection 4 is 20 °, and optimal is 15 °, and the shape of projection 4 can also basis
It is actually needed and is selected, in the present embodiment, the rectangular triangle of vertical section of projection 4.
The distance (i.e. the vertical range of tapered connection 3) of upper gasket 1 and lower gasket 2 is 0.8~1.2mm, this reality
Apply in example, the distance of upper gasket 1 and lower gasket 2 is 1mm.
In the present embodiment, in first along 11 and first the distance between the outer 12, in second along 21 and second outer 22 it
Between distance, identical along the horizontal range three between 11 and the second outer 22 in first, in the present embodiment, along 11 Hes in first
The distance between first outer 12 is 0.8~1.2mm, in second along 21 and second the distance between outer 22 for 0.8~
1.2mm, the horizontal range in first along 11 and second between outer 22 is 0.8~1.2mm.
When in use, upper gasket 1, the distribution of lower gasket 2 offset the spacer for bolt of the present invention with screw and nut, will
During screw and nut are tightened, tapered connection 3 can act power, occur resist force to the contact surface of screw and nut
Effect, when screw occur in use vibrations etc. external force effect when, the resist force of tapered connection 3 can offset external force
Effect, it is to avoid spacer for bolt is relatively moved with screw, nut.
Meanwhile, the tip of raised 4 structural top can produce frictional force, the side of frictional force with screw, the nut being in contact
It is in opposite direction to the relative movement with screw, nut, it is to avoid nut loosens.
The present invention is not limited to the above-described embodiments, for those skilled in the art, is not departing from
On the premise of the principle of the invention, some improvements and modifications can also be made, these improvements and modifications are also considered as the protection of the present invention
Within the scope of.The content not being described in detail in this specification belongs to prior art known to professional and technical personnel in the field.
