Abstract
The utility model provides an arc bolt. The arc bolt comprises an arc nut, a screw rod and a bolt end portion arranged at the lower end of the screw rod, wherein a thread is arranged at the periphery of the screw rod, a gasket is arranged between the arc nut and the screw rod, anti-skidding teeth are arranged at the lower end of the gasket, a concave groove is formed in the middle of the arc nut, and the radian of the arc nut is 20 degrees. According to the arc bolt, the anti-skidding teeth arranged at the lower end of the gasket prevent the bolt from slipping when the bolt is fixed, and increase the friction force between the bolt and a contacted surface.
Description
Technical field
The utility model relates to technical field of fastening, particularly a kind of circular arc bolt.
Background technique
Fastening piece is to be fastenedly connected with and to use very widely class mechanical parts, on various machineries, equipment, vehicle, boats and ships, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc., can see fastening piece miscellaneous, its feature is that description is various, the performance purposes is different, and standardization, seriation, unitized kind of degree are also high, therefore also have the people that one class fastening piece of existing NBS is called standard fasteners.
Bolt smooth surface commonly used, frictional force is little, and it is firmly inadequate when connecting, and easily comes off, and bolt can not normally be used, and causes the frequent bolt, the waste material.
Summary of the invention
For addressing the above problem, the utility model discloses a kind of circular arc bolt, the setting of the slideproof tooth under the pad prevents that bolt from skidding fixedly the time, increase the frictional force of bolt and surface of contact.
The utility model provides a kind of circular arc bolt, described circular arc bolt comprises circular arc nut, screw rod, and the bolt head that is arranged on described screw rod lower end, described screw rod outer rim is provided with screw thread, be provided with pad between described circular arc nut and the screw rod, described pad lower end is provided with slideproof tooth, is provided with groove in the middle of the described circular arc nut, and the radian of described circular arc nut is 20 °.The purpose of this utility model designs a kind of circular arc bolt, and the setting of the slideproof tooth under the pad prevents that bolt from skidding fixedly the time, increases the frictional force of bolt and surface of contact, and this model utility is simple in structure, long service life.
The utility model discloses a kind of a kind of improvement of circular arc bolt, 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 of circular arc bolt, described slideproof tooth is at least 2 roads.This improvement is at least 2 roads with the slideproof tooth setting, and purpose is the frictional force that increases bolt and surface of contact, prevents that bolt from skidding fixedly the time.
The purpose of this utility model designs a kind of circular arc bolt, and the setting of the slideproof tooth under the pad prevents that bolt from skidding fixedly the time, increases the frictional force of bolt and surface of contact, and this model utility is simple in structure, long service life.
