Description
Technical field
The invention belongs to field of mechanical technique, relate in particular to a kind of loose-proof screw.
Background technology
Screw is common connector, is mainly used for fastening two or more objects, when the time is longer or
Have under frequent shock conditions, screw can be made to generate loosening, and the object of fastening is caused to loosen, gently then leads to various losses, weight
Safety is then threatened, in order to avoid loosening hidden danger, needs a large amount of human and material resources periodically to be patrolled, this, which is just considerably increased, makes
Use cost.For case above, Chinese patent notification number：CN2481897Y was disclosed on March 13rd, 2002 " does not loosen anti-back
Screw ", the anti-loosening of screw, but patent fixed screw by the way of gluing are used for using screw rod with groove, due to
Glue itself at any time, the variations such as temperature, environment and vibrations be easy aging, to cause loosened screw fastening failure, do not loosen effect
Fruit is bad.
Invention content
It is an object of the invention to a kind of anti-loosening effect for overcoming disadvantages mentioned above and providing is lasting, simple in structure is locking
Dynamic screw.
The object of the invention and its technical problem underlying is solved using following technical scheme to realize：
The loose-proof screw of the present invention, including screw rod, elastic ring, nut, elastic ring are set on screw rod, and nut connects with screw rod
It connects, wherein：The screw rod body of rod is symmetrically provided with two groove A, groove B, and elastic ring periphery is made of several groups shrapnel group, shrapnel group by
Fixinig plate is composed with shrapnel；Elastic ring inner ring is matched equipped with tenon A, tenon B with two groove A, the groove B of screw rod 1；
A circle helical teeth is uniformly provided in nut fastening face, a piece of shrapnel on elastic ring is engaged with helical teeth.
The present invention compared with the existing technology has clear advantage and advantageous effect.By above technical scheme it is found that this hair
Bright elastic ring periphery is made of several groups shrapnel group, and shrapnel group is composed of fixinig plate and shrapnel, and nut rotates clockwise
When compressing elastic ring, the shrapnel on elastic ring generates deformation by pressure, is stuck on the helical teeth of nut, and nut is fastened with screw rod, works as spiral shell
When female rotation counterclockwise, the helical teeth of any a piece of shrapnel nut even at the cost of one's life, counterclockwise to prevent nut rotate there may be
Loosening.The design of elastic ring upper convex tenon A, tenon B, the tenon A of elastic ring, tenon B block respectively when elastic ring being made to be inserted in screw rod
In the groove A, groove B of screw rod, such elastic ring would not be rotated with screw rod generates mutually movement, and can only be done on screw rod
It is axially moved.The dual anti-loosening design of the present invention so that anti-loosening effect is lasting, and simple in structure.

Specific implementation mode
Below in conjunction with attached drawing and preferred embodiment, to the specific implementation mode of the loose-proof screw proposed according to the present invention,
Structure, feature and its effect are described in detail as after.
Referring to Fig. 1 to Fig. 3, loose-proof screw of the invention, including screw rod 1, elastic ring 2, nut 3, elastic ring 2 are set in
On screw rod 1, nut 3 is connect with screw rod 1, wherein：1 body of rod of screw rod is symmetrically provided with two groove A4, groove B5,2 periphery of elastic ring
It is made of several groups shrapnel group, shrapnel group is composed of fixinig plate 10 and shrapnel 9；2 inner ring of elastic ring is equipped with tenon A6, tenon
B7 is matched with two groove A4, the groove B5 of screw rod 1；A circle helical teeth 8 is uniformly provided in 3 fastening face of nut, on elastic ring 2
A piece of shrapnel 9 is engaged with helical teeth 8.
In use, elastic ring 2 is inserted in screw rod 1, tenon A6, the tenon B7 of elastic ring 2 are stuck in the groove of screw rod 1
In A4, groove B5, such elastic ring 2 would not be rotated with screw rod 1 generates mutually movement, and axial fortune can only be done on screw rod
It is dynamic.When nut 3 rotates clockwise compression elastic ring 2, the shrapnel 9 on elastic ring 2 is pressed the helical teeth 8 for generating deformation, being stuck in nut 3
On, nut 3 is fastened with screw rod 1.When nut 3 rotates counterclockwise, the helical teeth 8 of any group of shrapnel 9 nut 3 even at the cost of one's life, shrapnel 9
It is engaged with helical teeth 8, to prevent the issuable loosening of rotation counterclockwise of nut 3.
When needing Unscrewed screw, a cylinder type tool only need to be used, shrapnel 8 is pushed down from 3 outer ring of nut, makes shrapnel 9 from spiral shell
Deviate from the helical teeth 8 of mother 3, then can loose nut 3 with the tool of spanner one kind.
The above described is only a preferred embodiment of the present invention, being not intended to limit the present invention in any form, Ren Hewei
Be detached from technical solution of the present invention content, according to the technical essence of the invention to made by above example it is any it is simple modification, etc.
With variation and modification, in the range of still falling within technical solution of the present invention.
