Abstract
The utility model relates to a nut technique field in particular to disclosing a nut against theft and dropping. The technique case of the utility model is the following: the utility model includes a matrix with an internal screw thread, and the circumferential direction of the internal screw thread contains at least a groove with a smooth arc surface. A block against dropping is movably arranged at a side of the groove with the same direction as the procession direction of the matrix. The shape of the block against dropping is matching with the shape of the groove containing the block against dropping. As a further improvement, the side near to the middle of the block against dropping at the groove is movably arranged with a deep rolling ball against dropping with the diameter shorter than the middle position of the groove. The utility model solves the problem of being thieving and dropping by the violent vibration and other external strength, advantaging with a simple structure and easy operation.
Description
Technical field
The utility model belongs to the nut technical field, particularly a kind of antitheft screwed retaining ring.
Background technique
At present, in the connection set that adopts bolt and nut to connect, nut is under the effect of violent shaking force, easily loosening even come off, cause link to come off, especially the link that is running up, people come off in order to prevent nut, the pin that prevents nut loosening is installed on axle, can prevents the harm that comes off and cause because of nut like this, still, for being exposed to outside nut, more especially the nut made from noble metal as the nut on the freeway guardrail, is again the object that the lawless person steals.
The model utility content
The technical problem that the utility model solves just provides and a kind ofly can prevent the stolen nut that comes off of preventing again.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: antitheft screwed retaining ring, comprise the parent that has internal thread, at described internal thread at least one slick and sly cambered surface groove is arranged circumferentially, place anti-drop block with the corresponding to side activity of parent precession direction in this groove, the shape of described anti-drop block is complementary with the shape of placing non-slipping block place groove.
Its additional technical feature is: the one side that described anti-drop block is positioned at the parent radially inner side has non-slip process; Described non-slip process tilts to the opposite direction of parent precession direction; Described groove is a plurality of and is parallel to each other; Described groove is a plurality of, and is evenly distributed on the parent inboard; Anti-drop block is placed with the anticreep ball near a side activity in groove neutral position in described groove, and the diameter of described ball is slightly less than the degree of depth in groove neutral position; Described anticreep ball is spherical; Described anticreep ball is cylindric; Described parent is a multi-edge column-shaped; Described parent is cylindrical.
Antitheft screwed retaining ring provided by the utility model is compared with prior art and is had the following advantages: one, owing to circumferentially have at least one slick and sly cambered surface groove at described internal thread, in this groove, place anti-drop block with the corresponding to end activity of parent precession direction, the shape of this anti-drop block is complementary with the shape of placing non-slipping block place groove, when firmly screwing nut, anti-drop block is positioned at groove, nut is inwardly precession under the effect of external force, when nut oppositely comes off, anti-drop block is under the effect of screw rod frictional force, a side shifting that in groove, does not have anti-drop block, the end that non-slipping block is thicker radially moves inward to parent under the effect of groove diapire, make nut and screw rod compress, nut can not rotate relative to screw rod; Its two because the one side that anti-drop block is positioned at the parent radially inner side has non-slip process, when making the nut backward rotation, the friction that has increased screw rod and anti-drop block has prevented to skid between anti-drop block and the screw rod; They are three years old, because anti-drop block has spherical or columned anticreep ball near a middle side in described groove, and the diameter of ball is slightly less than the degree of depth in groove neutral position, when making the nut backward rotation, anti-drop block promotes the bigger anticreep ball of hardness, has both increased the pressure between nut and the screw rod, has prevented that again external force is excessive, damage anti-drop block, played the effect of double insurance; Its four because described groove is a plurality of, and it is inboard or be parallel to each other to be evenly distributed on parent, for large-scale nut, plays better antitheft anticreep effect.

Embodiment
Below in conjunction with accompanying drawing antitheft screwed retaining ring provided by the utility model is described in further detail:
As depicted in figs. 1 and 2, this antitheft screwed retaining ring comprises parent 1, in parent 1, have internal thread 2, circumferentially have a slick and sly cambered surface groove 4 that the centre is dark, two is shallow at internal thread 2, as shown in Figure 3, the number of groove 4 also can be two, and plural groove 4 can also be set according to the width of parent 1.Each groove 4 is separated by a distance, and parallel to each other.With the movable anti-drop block 5 of placing of the corresponding to end of parent 1 precession direction, anti-drop block 5 adopts rubber and plastics etc. wear-resisting and have certain degree of hardness and elastic material is made in each groove 4.The shape of anti-drop block 5 is complementary with the shape of placing non-slipping block 5 place's grooves.In the time of in anti-drop block 5 is placed on groove 4, anti-drop block 5 radially inner side faces roughly flush with or slightly higher than the inner side surface of internal thread 2 with the inner side surface of internal thread 2.In order to increase the frictional force of anti-drop block 5 and screw rod, worn non-slip process 3 at the radially inner side that is positioned at parent 1 of anti-drop block 5.Non-slip process 3 tilts to the opposite direction of parent precession direction.
In order to improve the antitheft anticreep performance of nut, especially for the heavy caliber nut, the number of groove 4 can be for a plurality of, and evenly distribute along the internal thread circumference of parent 1, are illustrated in figure 4 as three.Certainly, groove 4 can be not at grade.
When using, anti-drop block 5 and anticreep ball 6 are put in the groove 4, with this nut sleeve on screw rod, precession nut firmly, when the nut precession, anti-drop block 5 and anticreep ball 6 are arranged in groove 4, nut screws.When under external force, when nut is desired backward rotation, anti-drop block 5 produces friction with screw rod, under the effect of frictional force, move to an end that does not have anti-drop block bottom along groove 4, promotes anticreep ball 6 and move, and makes anticreep ball 6 be squeezed between nut and the screw rod, prevented relatively rotating of screw rod and nut, reached antitheft and effect anticreep.
