Abstract
The utility model provides a screw with antiskid teeth. The screw comprises a screw head and a screw rod, wherein a connecting piece is arranged between the screw head and the screw rod; the diameter of the screw rod is less than the diameter of the connecting piece; outriggers 1 and 2 are arranged below the screw rod; a gap is left between the outriggers 1 and 2; and a groove is formed in the upper end of the screw head, and the antiskid teeth are formed on the lower end of the screw head at equal distance. The screw with the antiskid teeth is designed, the friction force of the screw is increased through arranging the antiskid teeth, accordingly, a bolt sliding phenomenon is avoided, the failure ratio of equipment is reduced, and potential safety hazards are decreased.
Description
Technical field
The utility model relates to technical field of fastening, particularly a kind of screw with slideproof tooth.
Background technique
Screw is a class fastening piece that is made of head and screw rod two-part, can be divided three classes by purposes: machine screw, Cock screw and specific use screw, machine screw is mainly used in the part of a clamp screw pit, and being fastenedly connected between part that has a through hole, (this Connecting format is called screw and connects, and also belongs to removably connect not need the nut cooperation; Also can cooperate with nut, be used for being fastenedly connected between two parts that have a through hole.) Cock screw is mainly used in fixing two relative positions between the part, the specific use screw for example has lifting bolt etc. to use for the lifting part.
Usually the user is when oncomelania is followed closely, and needs spanner to be enclosed within the periphery of screw, the application of force then, and the situation that this polygonal is stressed usually causes the skidding of screw, causes operational mistake, has brought inconvenience to the user to a great extent, and has influenced using effect.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of screw with slideproof tooth, the setting of slideproof tooth increases the frictional force of screw, thereby prevents the phenomenon that skidding appears in bolt, reduces breakdown rate, reduces potential safety hazard.
The utility model provides a kind of screw with slideproof tooth, comprise screw head, screw rod, be provided with link between described screw head and the screw rod, the diameter of described screw rod is less than the diameter of link, have supporting leg one and supporting leg two at described screw rod, gapped between described supporting leg one and the supporting leg two, be provided with groove in described screw head upper end, the screw head lower end is provided with slideproof tooth, described slideproof tooth spaced set.A kind of screw with slideproof tooth of the purpose of this utility model design, the setting of slideproof tooth, the frictional force of increase screw, thereby prevent the phenomenon that skidding appears in bolt, reduce breakdown rate, reduce potential safety hazard, this model utility is simple in structure, easy to use, and low cost of manufacture.
The utility model discloses a kind of a kind of improvement with screw of slideproof tooth, described groove is cross recess or straight groove, and the degree of depth of described groove is 3-5mm.This improvement groove is set to cross recess or straight groove, makes things convenient for instrument to turn bolt, and the degree of depth of groove is 4mm, and effect is best, turns to such an extent that instrument can not skid.
The utility model discloses a kind of a kind of improvement with screw of slideproof tooth, the width in the gap between described supporting leg one and the supporting leg two equates with the width of supporting leg.This improvement equates its width, guarantees the soundness of screw, prolongs the working life of screw.
A kind of screw with slideproof tooth of the purpose of this utility model design, the setting of slideproof tooth, the frictional force of increase screw, thereby prevent the phenomenon that skidding appears in bolt, reduce breakdown rate, reduce potential safety hazard, this model utility is simple in structure, easy to use, and low cost of manufacture.
