Abstract

The utility model discloses an antiskid and anti-loose bolt, comprising a screw and a nut, which is characterized in that: the medial surface of the screw (1) cap is provided with a tooth thread (3); the medial surface of the nut (2) is provided with a tooth thread (4). The utility model provides a fastener which can prevent loose and skid and has the advantages of simple structure, convenient manufacturing, costs saving, as well as low producing costs.

Description

A kind of anti-skidding chek bolt

Technical field:

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

Technical background:

The connection of equipment and fastening in, adopt standard fasteners---bolt mostly, these standard fastenerss connect and fasteningly do the time spent in performance, a shortcoming is all arranged, be exactly loosening easily, the anti-loose method that adopts is with locking spring or check pin at present, but when fastening and dismounting workpiece, with present standard fasteners bolt, all necessary with two spanners, otherwise nut and then changes during tight screw rod, and screw rod and then changes during tight nut, if having only a wrench in the hand, it is fastening just to be difficult to finish workpiece, particularly for some workpiece, on one side can not enter spanner the time, just very troublesome.

Summary of the invention:

Technical problem to be solved in the utility model provides locking anti-skidding and simple in structure, easily manufactured, the bolt that cost of production is low of a kind of energy.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: be provided with the tooth line on the spiro rod cap inner side surface; Be provided with the tooth line at the nut inner side surface.

Adopt the bolt after the technique scheme, in use, the tooth line on the bolt contacts with fastener, has improved the pressure on the unit area, has promptly increased pressure, has just increased friction, not only can be anti-skidding but also can prevent bolt looseness; In use, generally cooperate with a plain nut with a screw rod that has the tooth line, or cooperate with a common screw with a nut that has the tooth line, generally both do not use simultaneously; When clamping bolt, as long as with one one on the fastening screw rod of not establishing the tooth line of spanner or nut, the other end need not just bolt to be tightened with spanner, like this equally during dismounting, like this, can also save plain cushion and bullet pad, improved installation efficiency, for those inconvenience is installed, an end bad enter spanner or the not enough again position of the big another hand distance of workpiece provide convenience, remodeling and production are easily, as long as mould Jia Keya line with the original production plain bolt, punching press just can be produced, so it is locking anti-skidding and simple in structure that the utility model provides a kind of energy, easily manufactured, save cost and the low fastening piece of cost of production.

Description of drawings:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model user mode schematic representation.

Embodiment:

Referring to Fig. 1, on screw rod 1 cap inner side surface, be provided with tooth line 3; Be provided with tooth line 4 at nut 2 inner side surfaces.

In use, the tooth line on the bolt contacts with fastener, has improved the pressure on the unit area, has just increased friction, not only can be anti-skidding but also can prevent bolt looseness; Referring to Fig. 2, in use, generally cooperate with a plain nut, or cooperate with a common screw with the nut 2 of a band row tooth line with a screw rod 1 that has the tooth line; Generally both do not use simultaneously.When clamping bolt, as long as with one one on the fastening screw rod of not establishing the tooth line of spanner or nut, the other end need not just bolt to be tightened with spanner, and is like this equally during dismounting, like this, can also save plain cushion and bullet pad.

Claims

A kind of anti-skidding chek bolt comprises screw rod and nut, it is characterized in that: be provided with tooth line (3) on described screw rod (1) cap inner side surface; Be provided with tooth line (4) at described nut (2) inner side surface.
