Abstract
The invention discloses an anti-theft nut sleeve. The anti-theft nut sleeve comprises a nut sleeve block, a ring washer and a swirl sleeve; one end of the nut sleeve block is set to be a hexagon groove capable of being arranged on a nut in a sleeved manner and matched with the nut, the other end of the nut sleeve block is set to be a screw hole allowing a bolt to be screwed, a first groove is formed in the middle portion of the outer surface of the nut sleeve block, and the ring washer is embedded into the first groove; one end of the swirl sleeve is provided with a screw hole allowing a bolt to be screwed, the other end of the swirl sleeve is opened, the nut sleeve block is contained in the swirl sleeve, and is connected with the swirl sleeve through a fixing point, and the ring washer is embedded into a second groove in the inner side of the swirl sleeve; and the axial direction of the ring washer coincides with the axial directions of the nut sleeve block and the swirl sleeve. The anti-theft nut sleeve can be widely applied to threaded connection for railways, high voltage towers, bridges and common machines.
Description
Technical field
The invention belongs to fastener areas, be specifically related to a kind of anti-theft screw cap cover.
Background technique
Traditional nut appearance profile is all designed to standardized positive hexagonal column, to reach unified, general and to facilitate the object of turn.But, though above-mentioned nut has revolve lock bolt, and then the effect of mounting article, but also because it can by standardized tool, as adjustable spanner, socket wrench etc., can revolve easily and open nut and take off object, cause object stolen, this situation is common in outdoor power equipment, machinery etc., bring massive losses to safety in production and national wealth.
Summary of the invention
For solving the problem, the invention provides a kind of anti-theft screw cap cover, this spiro cap is easy and simple to handle, effectively can improve anti-theft effect.
The object of the invention is to realize in the following manner:
A kind of anti-theft screw cap cover, comprises spiro cap block, ring washer and turn sleeve; Described spiro cap block one end is set as and can be enclosed within nut and the hex-shaped recess matched with it, and the other end is set as the screw for screw threaded, and be provided with the first groove in the middle part of the outer surface of spiro cap block, ring washer is nested in the first groove; Turn sleeve one end offers the screw for screw threaded, and the other end is uncovered, and spiro cap block is placed on the inside of turnbarrel, is associated with turnbarrel by immovable point, and ring washer is nested in the second groove of the inner side of turnbarrel; The axis of ring washer and spiro cap block, turnbarrel axial consistent.
Described immovable point comprises the hemispherical projections and hemispherical depression that match, and hemispherical projections is arranged on turn sleeve, and hemispherical depression is arranged on spiro cap block; Or hemispherical depression is arranged on turn sleeve, and hemispherical projections is arranged on spiro cap block.
The outside of described turnbarrel 3 is hexagonal cylinder.
Relative to prior art; the present invention is together with spiro cap; be tightened in after on bolt; immovable point between swivel nut cover block and turn sleeve is separated; now form stripped thread state, now turn turn sleeve, spiro cap block also can not rotate; effectively protect swivel nut, thus protect the object of swivel nut and bolt tightening.The present invention can be widely used in railway, high tension electric tower, bridge, and being threaded of conventional machinery.
Accompanying drawing explanation
Fig. 1 is 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 cover, comprises spiro cap block 1, ring washer 2 and turn sleeve 3; Described spiro cap block 1 one end is set as and can be enclosed within nut 4 and the hex-shaped recess 11 matched with it, and the other end is set as the screw 13 screwed togather for bolt 5, and be provided with the first groove 12 in the middle part of the outer surface of spiro cap block 1, ring washer 2 is nested in the first groove 12; Turn sleeve 3 one end offers the screw 31 for screw threaded, and the other end is uncovered, and spiro cap block 1 is placed on the inside of turnbarrel 3, is associated with turnbarrel 3 by immovable point, and ring washer 2 is nested in the second groove 32 of the inner side of turnbarrel 3; The axis of ring washer 2 and spiro cap block 1, turnbarrel 3 axial consistent.
Described immovable point comprises the hemispherical projections 33 and hemispherical depression 14 that match, and hemispherical projections 33 is arranged on turn sleeve 3, and hemispherical depression 14 is arranged on spiro cap block 1; Or hemispherical depression is arranged on turn sleeve, and hemispherical projections is arranged on spiro cap block.
The outside of described turnbarrel 3 is hexagonal cylinder, conveniently uses existing wrench operated.
Specific works process of the present invention is as follows:
Pad 2 and spiro cap block 1 are combined, now pad 2 and spiro cap block 1 geo-stationary, be placed in turnbarrel 3; Immovable point association between spiro cap block 1 and turnbarrel 3, now spiro cap block 1 and turnbarrel 3 geo-stationary, therefore spiro cap block 1, pad 2 and turnbarrel 3 geo-stationary.The present invention is socketed upper cap nut 4; aim at screw hole; with spanner, nut 4 is tightened on bolt 5 together with anti-theft screw cap cover; tighten in process; turnbarrel 3 wall and spiro cap block 1 are subject to identical power; when tightening; spiro cap block 1 relatively turnbarrel has downward displacement; therefore; hemispherical projections 33 on turnbarrel 3 and the hemispherical depression 14 on spiro cap block 1 depart from; forming stripped thread state, only can there is relative movement in spiro cap block 1 and turnbarrel 3, thus protection nut 4 and bolt 5 are not destroyed.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for a person skilled in the art, and not departing under general idea prerequisite of the present invention, can also make some changes and improvements, these also should be considered as protection scope of the present invention.
