Abstract
The invention discloses a kind of Novel anti-loosing bolts, including screw rod, the first locking member and the second locking member, first locking member includes the first nut and the boss being wholely set with the first nut and a Small Taper ringfeder, the outer wall of the boss is equipped with the first external screw thread, and the first locking member inner wall is equipped with and matched first internal screw thread of the screw rod;Second locking member includes the second nut, second nut inner wall both ends are respectively equipped with the second internal screw thread and third internal screw thread with first external screw thread and screw rod cooperation, it is equipped with the inner conical surface being interference fitted with the Small Taper ringfeder in the middle part of the inner wall of second nut, there is bias in the axle center of second nut and the first nut.The present invention uses new construction, it is ensured that bolt strength, it is locking more reliable, and it can solve the secure connection for vibrating big or the big equipment of the temperature difference.
Description
Technical field
The present invention relates to connector technical fields, and in particular to a kind of Novel anti-loosing bolt.
Background technique
Threaded connection is that our the daily connection types being widely used connect under dead load with installation, disassembly simplicity
Intensity is high, securely and reliably;But it under the larger equal environment of dynamic loading or the temperature difference, is bolted and is easy to produce loosening, bonding strength disappears
It loses, causes that very big hidden danger will be brought in the equipment such as equipment fault, especially aircraft, railway and military affairs.
There are three types of anti-loose methods using: 1, friction is loosened, such as elastic washer, double nut and self-locking nut, makees
It is locking generally to commonly use.2, mechanical locking, such as split pin, stop washer, slotted nut, it is locking relatively reliable.3, spiral shell is destroyed
Line pair is locking, such as welding, gluing, and non-dismountable and locking is less susceptible to check internal damage degree.
With the needs of locking thread, occurs two kinds of locking connection methods of new construction, 1, the distribution of left-right rotary screw thread at present
At two sections of a screw rod, fastening part screw rod is greater than lock portion screw rod, and two nuts simultaneously tightly reach locking, and this structure is pre-
Clamp force cannot be big, because lock portion screw rod is small, a nut is simultaneously next, is squeezed and deformed for two nuts and generates pretightning force, is shaking
Under dynamic and big temperature change environment, screw rod, nut volume change, pretightning force can gradually be lost, cannot be locking.2, moral is breathed out by Japan
Lip river gram bolt locks first nut by the eccentricity pressure of second nut, and as pretightning force, two nuts and bolt
Occlusion it is each be biased to it is symmetrical it is symmetrical two lines that bolts and nuts are engaged maximum under stress, screw thread discontinuity on one side,
Influence fastening strength.
Summary of the invention
For above-mentioned technical deficiency, the object of the present invention is to provide a kind of Novel anti-loosing bolt, using new construction,
Ensure bolt strength, it is locking more reliable, it can solve the secure connection for vibrating big or the big equipment of the temperature difference.
In order to solve the above technical problems, the present invention adopts the following technical scheme:
The present invention provides a kind of Novel anti-loosing bolt, including screw rod, the first locking member and the second locking member, first lock
Tight part includes that the first nut and the boss being wholely set with the first nut and a Small Taper ringfeder, the outer wall of the boss are set
There is the first external screw thread, the first locking member inner wall is equipped with and matched first internal screw thread of the screw rod;Second locking member
Including the second nut, second nut inner wall both ends are respectively equipped with the with first external screw thread and screw rod cooperation
The inner wall middle part of two internal screw threads and third internal screw thread, second nut is equipped with the inner cone being interference fitted with the Small Taper ringfeder
There is bias in the axle center of face, second nut and the first nut.
The beneficial effects of the present invention are: the present invention uses new construction, it is ensured that bolt strength, it is locking more reliable, it can solve
Certainly vibrate big or the big equipment of the temperature difference secure connection.
Detailed description of the invention
In order to more clearly explain the embodiment of the invention or the technical proposal in the existing technology, to embodiment or will show below
There is attached drawing needed in technical description to be briefly described, it should be apparent that, the accompanying drawings in the following description is only this
Some embodiments of invention for those of ordinary skill in the art without creative efforts, can be with
It obtains other drawings based on these drawings.
Fig. 1 is a kind of structure sectional view of Novel anti-loosing bolt provided in an embodiment of the present invention.
Description of symbols:
1- screw rod, the first nut of 2-, 3- boss, 4- Small Taper ringfeder, the second nut of 5-.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of Novel anti-loosing bolt, including screw rod 1, the first locking member and the second locking member, the first locking
Part includes that the first nut 2 and the boss 3 being wholely set with the first nut 2 and a Small Taper ringfeder 4, the outer wall of boss 3 are set
There is the first external screw thread, the first locking member inner wall is equipped with and matched first internal screw thread of screw rod 1;Second locking member includes the second nut
5,5 inner wall both ends of the second nut are respectively equipped with the second internal screw thread and third internal screw thread with the first external screw thread and screw rod cooperation,
The inner conical surface being interference fitted with Small Taper ringfeder 4, the axle center of the second nut and the first nut are equipped in the middle part of the inner wall of second nut 5
There are bias, eccentricity α.
The first nut 2 is first tightened when installation on screw rod, then installs and tightens the second nut 5, with 5 precession of the second nut,
Its inner conical surface and the cooperation of Small Taper ringfeder 4 compress, and compress the Small Taper ringfeder 4 of the first nut 2, cause Small Taper ringfeder 4
The screw thread of the internal screw thread and screw rod 1 that divide, which all compresses, to be held tightly, and gapless, formation first layer are locking;Second nut, 5 rear portion third
Internal screw thread has the eccentricity of a very little, and it is always bolt that eccentricity α, which has a pressing force when tightening with the first external screw thread,
It is locking to form the second layer for pretightning force.
To sum up, the present invention uses above-mentioned two layers of anti-loose structure, and tensioner locking screw thread it is big to hold threaded area tightly, it is ensured that bolt
Intensity and fastening.
Obviously, various changes and modifications can be made to the invention without departing from essence of the invention by those skilled in the art
Mind and range.In this way, if these modifications and changes of the present invention belongs to the range of the claims in the present invention and its equivalent technologies
Within, then the present invention is also intended to include these modifications and variations.
