Abstract

The utility model provides an anti-slip bolt. The anti-slip bolt comprises a nut, a screw and a point part arranged at the lower end of the screw, wherein a semicircular washer is arranged between the nut and the screw, a slot perpendicular to the screw is formed in the nut, the slot is strip-shaped, and threads are arranged on the outer edge of the screw. The anti-slip bolt has the advantages that a user can insert a tool into the nut, the bolt is prevented from slipping when the bolt is rotated due to the arrangement of the slot and is effectively driven to rotate, and the bolt can better penetrate into objects such as a plate due to the arrangement of the pointed head.

Description

A kind of bolt of anti-slip

Technical field

The utility model relates to a kind of fastening piece, particularly a kind of bolt of anti-slip.

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.

Usually the user is when twisting bolt, needs spanner to be enclosed within the periphery of nut, the application of force then, and the situation that this polygonal is stressed usually causes the skidding of bolt, causes operational mistake.

Summary of the invention

For addressing the above problem, the utility model discloses a kind of bolt of anti-slip, the user can insert nut with instrument, and the setting of slotted eye prevents that bolt from skidding when rotated, can effectively drive the rotation of bolt, the setting of tip makes bolt can better go deep into the objects such as plate.

The utility model provides a kind of bolt of anti-slip, described bolt comprises nut, screw rod, and the tip that is arranged on described screw rod lower end, be provided with packing ring between described nut and the screw rod, described packing ring semicircular in shape, described nut is provided with the slotted eye vertical with screw rod, and described slotted eye is " one " font, and described screw rod outer rim is provided with screw thread.The purpose of this utility model designs a kind of bolt of anti-slip, the user can insert nut with instrument, the setting of slotted eye prevents that bolt from skidding when rotated, can effectively drive the rotation of bolt, the setting of tip makes bolt can better go deep into the objects such as plate, this model utility is simple in structure, and material is relatively economized long service life.

The utility model discloses a kind of a kind of improvement of bolt of anti-slip, described tip is triangular pyramidal.This improvement is arranged on triangular pyramidal with the tip, makes bolt can effectively go deep into the objects such as plate, makes it fixing more firm.

The utility model discloses a kind of a kind of improvement of bolt of anti-slip, the length of described screw rod is the 40%-65% of bolt total length.The length of the utility model screw rod is that the bolt total length is long, and the waste material does not have fastening effect, and the length of screw rod is that the bolt total length is 60% after tested, and effect is better.

The purpose of this utility model designs a kind of bolt of anti-slip, the user can insert nut with instrument, the setting of slotted eye prevents that bolt from skidding when rotated, can effectively drive the rotation of bolt, the setting of tip makes bolt can better go deep into the objects such as plate, this model utility is simple in structure, and material is relatively economized long service life.
