Description
A kind of anti-theft screw cap set
Technical field
The invention belongs to fastener areas, and in particular to a kind of anti-theft screw cap set.
Background technology
Traditional nut appearance profile is designed to the positive hexagonal column of standardization, to reach unified, general and convenient rotation
Dynamic purpose.However, though above-mentioned nut has rotation lock bolt, and then the effect of fixed object, also because it can be by standardization
Instrument, such as monkey wrench, box spanner etc., you can rotation opens nut and removes object easily, causes object stolen, the situation is common
In outdoor power equipment, plant equipment etc. brings massive losses to safety in production and national wealth.
The content of the invention
To solve the above problems, the present invention provides a kind of anti-theft screw cap set, the spiro cap is easy to operate, can effectively improve anti-
Steal effect.
The purpose of the present invention is realized in the following manner：
A kind of anti-theft screw cap set, including spiro cap block, ring washer and turnbarrel；Described spiro cap block one end is set as covering
On nut and matched hex-shaped recess, the other end is set as the screw screwed togather for bolt, the outer surface of spiro cap block
Middle part is provided with the first groove, and ring washer is nested in the first groove；Turnbarrel one end offers the screw screwed togather for bolt, separately
One end is opening, and spiro cap block is placed on the inside of turnbarrel, associated by fixing point with turnbarrel, and ring washer is nested in
In second groove of the inner side of turnbarrel；The axial direction of ring washer and spiro cap block, the axially consistent of turnbarrel
The fixing point includes the hemispherical projections and hemispherical depression matched, and hemispherical projections are arranged on turnbarrel
On, hemispherical depression is arranged on spiro cap block；Or, hemispherical depression is arranged on turnbarrel, hemispherical projections are arranged on
On spiro cap block.
The outside of the turnbarrel 3 is hexagonal cylinder.
Relative to prior art, the present invention and nut are nested together, after being tightened on bolt, swivel nut set block and turnbarrel
Between fixing point separation, now formed stripped thread state, now turn turnbarrel, spiro cap block will not also rotate, have
What is imitated protects swivel nut, so as to protect the object that swivel nut and bolt are tightened.It present invention can be widely used to railway, high-tension electricity
Tower, bridge, and standard machinery threaded connection.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the sectional view of turnbarrel of the present invention.
Embodiment
A kind of anti-theft screw cap set, including spiro cap block 1, ring washer 2 and turnbarrel 3；Described one end of spiro cap block 1 is set as
Hex-shaped recess 11 on nut 4 and matched can be enclosed on, the other end is set as the screw 13 screwed togather for bolt 5, spiro cap
The first groove 12 is provided with the middle part of the outer surface of block 1, ring washer 2 is nested in the first groove 12；The one end of turnbarrel 3 offers confession
The screw 31 that bolt is screwed togather, the other end is opening, and spiro cap block 1 is placed on the inside of turnbarrel 3, passes through fixing point and rotation
Sleeve 3 is associated, and ring washer 2 is nested in the second groove 32 of the inner side of turnbarrel 3；The axial direction of ring washer 2 and spiro cap block
1st, the axially consistent of turnbarrel 3
The fixing point includes the hemispherical projections 33 and hemispherical depression 14 matched, and hemispherical projections 33 are arranged on rotation
On rotaring sleeve 3, hemispherical depression 14 is arranged on spiro cap block 1；Or, hemispherical depression is arranged on turnbarrel, hemispherical
Projection is arranged on spiro cap block.
The outside of the turnbarrel 3 is hexagonal cylinder, convenient to be operated with existing spanner.
The specific work process of the present invention is as follows：
Pad 2 and spiro cap block 1 are combined, now pad 2 and the geo-stationary of spiro cap block 1, are placed on turnbarrel 3
It is interior,；Fixing point between spiro cap block 1 and turnbarrel 3 is associated, now spiro cap block 1 and the geo-stationary of turnbarrel 3, because
This spiro cap block 1, pad 2 and the geo-stationary of turnbarrel 3.The present invention is socketed upper cap nut 4, screw hole is directed at, will with spanner
Nut 4 and anti-theft screw cap set are tightened on bolt 5 together, and during tightening, the wall of turnbarrel 3 and spiro cap block 1 are by identical
Power, when tightening, spiro cap block 1, which rotates against sleeve, downward displacement, therefore, the hemispherical projections 33 on turnbarrel 3
Depart from the hemispherical depression 14 on spiro cap block 1, form stripped thread state, spiro cap block 1 and turnbarrel 3 can only occur relatively
Motion, so as to protect nut 4 and bolt 5 not to be destroyed.
Above-described is only the preferred embodiment of the present invention, it is noted that for those skilled in the art,
Under the premise of general idea of the present invention is not departed from, some changes and improvements can also be made, these should also be considered as the present invention's
Protection domain.
