Abstract

The utility model discloses a looseness prevention screw. The looseness prevention screw comprises a screw head and a threaded rod, wherein the screw head and the threaded rod are fixed to be of an integral structure, the cross section of the screw head is a regular hexagon, a flange is arranged at the junction position between the bottom end of the screw head and the threaded rod, through holes are formed in the flange, and a screw body penetrates through each through hole, and is parallel to the threaded rod. The screw bodies penetrate through the two through holes in the flange respectively. The looseness prevention screw has the advantages that after the threaded rod penetrates into an object to carry out locking, the threaded rod continues penetrating into the object through the screw bodies in the flange, looseness cannot easily happen between the threaded rod and the object, and the purpose of looseness prevention is achieved.

Description

A kind of loose-proof screw

Technical field

The utility model relates to a kind of screw, relates in particular to a kind of loose-proof screw.

Background technique

Screw is the mechanical parts that connect use, and screw thread is arranged on round bar, can lock and two objects.But, fixedly after certain hour, due to the effect of external force, usually make loosened screw, even come off.Such as the bicycle basket in bicycle handlebar the place ahead, the time one is long, and its retaining screw just often comes off, and makes it to lose corresponding function.

The model utility content

The purpose of this utility model is to provide a kind of loose-proof screw, and is both attractive in appearance, and dismounting is also convenient.

Realize that the utility model purpose technological scheme is: a kind of loose-proof screw comprises: spiral shell head, screw rod; Spiral shell head and the screw rod structure that is fixed as one, the cross-section area of described spiral shell head is regular hexagon; Described spiral shell head bottom and screw rod junction arrange flange, have through hole on described flange, have a screw to pass this through hole.

Further, pass the screw of described through hole parallel with described screw rod.

Further, have two through holes on described flange, the line between two through holes passes the center line of screw rod and spiral shell head.

Further, have respectively screw in two through holes on described flange and pass described two through holes.

The utlity model has positive effect: when screw rod pierce object lock and after, continuing to pierce this object by the screw in flange, make screw rod and object be not easy to become flexible, reach anti-loosening purpose.

Description of drawings

Fig. 1 is the utility model embodiment's structural representation.

In figure: 1, spiral shell head; 2, screw rod; 3, flange; 4, through hole; 5, screw.

Embodiment

With reference to shown in Figure 1, a kind of loose-proof screw that the present embodiment provides comprises: spiral shell head 1, screw rod 2; Spiral shell head 1 and screw rod 2 structure that is fixed as one, the cross-section area of described spiral shell head 1 is regular hexagon; Described spiral shell head 1 bottom and screw rod 2 junctions arrange flange 3, have through hole 4 on described flange 3, have a screw 5 to pass this through hole 4.

The screw 5 that passes described through hole 4 is parallel with described screw rod 2.

Have the center line that line between 4, two through holes 4 of two through holes passes screw rod 2 and spiral shell head 1 on described flange 3.

Have respectively screw 5 in two through holes 4 on described flange 3 and pass described two through holes 4.

When screw rod 2 pierce that object is locked and after, continuing to pierce this object by the screw 5 in flange 3, make screw rod 2 and object be not easy to become flexible, reach anti-loosening purpose.
