Abstract
An anti-loose, anti-theft nut is provided and comprises a nut body. A screw hole is arranged on the nut body. An inner screw thread is provided on the inner wall of the screw hole. The utility model is characterized in that an anti-disassembling structure consisting of a through hole, a hoodle, a pushing spring and a sealing bolt is arranged on the nut body. The through hole travels through the outer wall of the nut body and reaches the inner wall of the screw hole. The axes of the through hole is in the direction of the tangent or the secant of the screw hole inner wall, and extends from the nut body outer wall to the rotary direction of the inner thread on the screw hole inner wall. The hoodle is sleeved at the end of the through hole near the screw hole. A through hole thread is arranged at the end of the through hole near the nut body outer wall. The sealing bolt is screwed into the end of the through hole near the nut body outer wall. The outer thread of the sealing bolt is matched with the through hole thread. The pushing spring is sleeved in the through hole and is nipped between the sealing bolt and the hoodle. The utility model can prevent automatic loosening and illegal dismounting of the nut.
Description
Technical field
The utility model relates to a kind of nut.
Background technique
Existing nut does not have the anti-loose anti-theft function usually.In the occasion that has, locate as electric power pylon in the power circuit etc., then require nut to have the anti-loose anti-theft function, to prevent that nut loosening from causing the accident or parts are stolen.Therefore, be necessary to provide a kind of anti-loose anti-theft nut.
The model utility content
The purpose of this utility model promptly provides a kind of nut of anti-loose anti-theft.
Anti-loose anti-theft nut of the present utility model has basal body of nut, basal body of nut is provided with tapped hole, the inwall of described tapped hole has internal thread, it is characterized in that basal body of nut is provided with by through hole, hoodle, the anti-structure of unloading that goring push spring and shutoff screw constitute, described through hole is led to the inwall of tapped hole by the basal body of nut outer wall, the axis of described through hole is positioned on the tangent line of tapped hole inwall or the secant direction and is pointed to the internal thread precession direction of tapped hole inwall by the basal body of nut outer wall, described hoodle is sleeved on an end of the close tapped hole of through hole, close basal body of nut outer wall one end of described through hole is provided with through hole whorl, described shutoff screw screws in an end of the close basal body of nut outer wall of through hole, outside thread on the described shutoff screw matches with this through hole whorl, and described goring push spring is placed in the through hole and is folded between shutoff screw and the hoodle.In the utility model, the axis of above-mentioned through hole is positioned on the tangent line or secant direction of tapped hole inwall, and not at the radial direction of tapped hole,
In the process of using the utility model nut, when being nested with nut on screw rod, under the effect of goring push spring, the hoodle that is sleeved in the through hole can expose and contacts with the sidewall of screw rod from the through hole port.At this moment, if allow nut rotate to the precession direction, the active force that the screw rod sidewall applies hoodle is tending towards hoodle is pushed direction in the through hole, promptly allows hoodle overcome the active force of goring push spring and shrinks back in through hole, thereby can not influence the precession of nut.Otherwise, if allow nut rotate to screwing out direction, friction between screw rod sidewall and the hoodle can outwards take hoodle out of from through hole and snap between screw rod sidewall and the through hole front end hole wall, and card is tight more more along with the continuation of the process of back-out, and nut is locked on the screw rod the most at last.In the utility model, the axis of above-mentioned through hole is positioned on the tangent line or secant (and having certain included angle between the tangent line) direction of tapped hole inwall, and not at the radial direction of tapped hole, this just can guarantee that hoodle can move in a manner described.
In the utility model, the above-mentioned anti-structure of unloading that is made of described through hole, hoodle, goring push spring and shutoff screw can be provided with a group or more (can be more than two groups as two groups).Above-mentioned anti-when unloading structure when many groups are set, unload under the acting in conjunction of structure in that each group is anti-, just can play better anti-loose anti-theft effect.
With regard to the utility model, traditional regular hexagon that the profile of above-mentioned basal body of nut can adopt, this kind profile is convenient to this product is used as the nut that plays the role of fastening.Simultaneously, the profile of basal body of nut can also adopt cylindrical other shape that waits, and at this moment, this product then can be used with other plain nut, promptly uses as retaining (locking) nut.
In the utility model, said shutoff screw is good with the screw that adopts special-shaped termination, and this kind screw needs just can unload with special tool.Like this, when the specialized maintenance personnel desire to unload lower nut, can unload this shutoff screw with special tool earlier, take out goring push spring again,, can normally screw out nut with strong magnets sucking-off hoodle.
Therefore, nut of the present utility model both can be dismantled by the professional workforce, had stopping function again, can prevent nut loosening voluntarily or other people illegally dismantle, when its electric power pylon in power circuit etc. is located to use, just can play the effect that prevents that parts are stolen.
Content of the present utility model further illustrates with the following Examples, but content of the present utility model is not limited only to content related among the embodiment.

Fig. 1 is the structural representation of nut among the embodiment.
Fig. 2 is the A of Fig. 1---the A sectional view.
Embodiment
As Fig. 1, shown in 2, nut in the present embodiment has basal body of nut 1, basal body of nut 1 is provided with tapped hole 2, the inwall of described tapped hole 2 has internal thread 3, it is characterized in that basal body of nut 1 is provided with by through hole 4, hoodle 5, the anti-structure of unloading that goring push spring 6 and shutoff screw 7 constitute, described through hole 4 is led to the inwall of tapped hole 2 by the basal body of nut outer wall, the axis of described through hole 4 is positioned on the tangent direction of tapped hole inwall, and point to the precession direction of the internal thread 3 of tapped hole inwall by the basal body of nut outer wall, described hoodle 5 is sleeved on an end of the close tapped hole of through hole 4, close basal body of nut outer wall one end of described through hole 4 is provided with through hole whorl, described shutoff screw 7 screws in an end of the close basal body of nut outer wall of through hole, outside thread on the described shutoff screw 7 matches with this through hole whorl, and described goring push spring 6 is placed in the through hole 4 and is folded between shutoff screw 7 and the hoodle 5.
During nut in using present embodiment, the hoodle 5 that is sleeved in the through hole 4 can expose and contacts with the sidewall of screw rod 8 from the through hole port.At this moment, if allow nut rotate to the precession direction, the active force that the sidewall of screw rod 8 applies hoodle 5 is tending towards hoodle is pushed direction in the through hole, and hoodle 5 can overcome the active force of goring push spring 6 and shrink back in through hole 4, can not influence the precession of nut.If allow nut rotate to screwing out direction, friction between the sidewall of screw rod 8 and the hoodle 5 can outwards take hoodle out of from through hole 4 and snap between screw rod sidewall and the through hole front end hole wall, and card is tight more more along with the continuation of the process of back-out, thereby nut is locked on the screw rod 8.
In the present embodiment, in order to play better anti-loose anti-theft effect, on basal body of nut 1, be provided with two groups of anti-structures of unloading that constitute by above-mentioned through hole 4, hoodle 5, goring push spring 6 and shutoff screw 7.
Nut in the present embodiment is for playing the nut of anti-loose anti-theft effect, and it normally is used with the plain nut that other play the role of fastening, in order to strengthen anti-theft effect, so adopted columned profile.
