Abstract
An anti-disassembly screw consists of a screw (1), a screw cap (2) arranged at the upper part of the screw (1), and a pair of forward-spinning oblique-arc retaining slanted strips (A) arranged at the periphery at the top of the screw cap (2). As at least one pair of the forward-spinning oblique-arc retaining slanted strips (A) are arranged at the periphery at the top of the screw cap (2) of the screw, when a screwdriver is adopted to screw the screw in the forward direction or the backward direction, the screw only can be screwed down but not screwed out, so that the anti-disassembly purpose of the screw is achieved when people do not want the screw to be dismantled.
Description
Technical field:
The present invention relates to the screw technology of anti-dismounting.
Background technique:
Present screw promptly can screw and can screw out by screw-driver, when people do not wish that the screw that screws is screwed out dismounting, has just felt simply helpless.---for example: do not remove when people do not wish to be fixed on the stolen person of the screw that screws on the air conditioner outdoor machine of Stall, yet prior art is insoluble.
Summary of the invention:
The present invention's purpose:
A kind of screw that changes the anti-dismounting of existing situation is proposed.
In order to realize the present invention, intend adopting following technology:
The present invention includes: screw and the nut that is arranged on this screw top is characterized in that: be provided with the oblique arc resistance retaining of at least one pair of dextrorotation slanted bar at the peripheral position at the top of nut.
The present invention and characteristics compared with the prior art:
Because the peripheral position at the top of the nut of screw is provided with the oblique arc resistance retaining of at least one pair of dextrorotation slanted bar, when screw-driver is screwed forward or backwards to the present invention, will cause the present invention can only be screwed the result that tightly can not screw out.
Description of drawings:
Figure has illustrated one embodiment of the present of invention.
1: screw; 2: nut; A: the oblique arc resistance retaining of dextrorotation slanted bar.
Embodiment:
The prior art screw roughly can be divided into self tapping screw and normal screws two big classes, on the basis of existing screw structural, the invention is characterized in: the peripheral position at the top of the nut 2 of screw is arranged to less the oblique arc resistance retaining of a pair of dextrorotation slanted bar A, the setting of the oblique arc resistance retaining of this dextrorotation slanted bar A, be when allowing screw-driver that the present invention is turned forward or backwards, produce the result who is different from existing screw.
When the present invention when being screwed clockwise by screw-driver owing to be subjected to stopping of the oblique arc resistance of a pair of dextrorotation retaining slanted bar A, so the present invention is stubborn more tight more by screw-driver; When the present invention is screwed out counterclockwise by screw-driver and since lack the oblique arc resistance of dextrorotation retaining slanted bar A stop that screw-driver will upwards slide and can not screw out the present invention.
Obviously, when the present invention is screwed by screw-driver at different direction, two kinds of distinct results can be produced, promptly the result that tightly can not be screwed out can only be screwed.
Claims (1)
1. the screw that can prevent dismantling, it comprises: screw (1) and the nut (2) that is arranged on this screw (1) top is characterized in that: be provided with the oblique arc resistance retaining of at least one pair of dextrorotation slanted bar (A) at the peripheral position at nut (2) top.
