Abstract

The utility model discloses a dysmorphism nut, it includes: coiled hair and double -screw bolt, the coiled hair sets up the one end at the double -screw bolt, the discharge orifice had been offered in the middle of the coiled hair is positive, be equipped with the chamfer between the up end of coiled hair and the side, the plane has been seted up down in a pair of direction of the other end of double -screw bolt, another the other side of the other end of double -screw bolt has upwards seted up the guide way, set up a fastening hole down on the plane, the inside of double -screw bolt is equipped with the screw. The utility model discloses simple structure, reasonable in design, the installation is easy with the dismantlement, and low in production cost has sufficient intensity and good manufacturability.

Description

A kind of special-shaped nut

Technical field

The utility model is related to tool fitting field, more particularly to a kind of special-shaped nut.

Background technology

Conventional screw cap is generally directly that in use, nut is easily straight with screw rod in the centrally disposed screw of nut body The situation of corrosion is received and sent, causes to be difficult to dismantle；And it is used in when on the machine for rocking, nut of long duration is with screw rod also Loosening can be produced.

Utility model content

The utility model mainly solving the technical problems that provide a kind of special-shaped nut, its is reasonable in design, simple structure, solution Nut of having determined is of long duration with Stud connection to get rusty not easy to remove, and produce that to rock be the easy problem for loosening.

In order to solve the above technical problems, the technical scheme that the utility model is used is to provide a kind of special-shaped nut, its Including：Coiled hair and stud；The coiled hair is arranged on one end of stud；The coiled hair middle offers flowing hole；The coiled hair Upper surface and side between be provided with chamfering；Lower plane is offered on a pair of directions of the other end of the stud；The stud Another other side of the other end offer gathering sill upwards；A fastener hole is opened up on the lower plane；The inside of the stud It is provided with screw.

Preferably, the coiled hair and stud are structure as a whole；

Preferably, the flowing hole is through hole；

Preferably, the gathering sill and lower plane have two respectively, and symmetrical along center line respectively；

Preferably, the fastener hole only one of which, can be arranged in an arbitrary plane.

The beneficial effects of the utility model are：The utility model simple structure, reasonable in design, installation and removal are easy, raw Low cost is produced, with enough intensity and good manufacturability；And oil can be fallen by flowing hole and enter nut, reduce nut and spiral shell The friction of bar, can also be by fastener hole, further clamping screw, reduces loosening rate.

Brief description of the drawings

Fig. 1 is a kind of schematic diagram of special-shaped nut of the utility model；

Fig. 2 is a kind of side view of special-shaped nut of the utility model；

The mark of each part is as follows in accompanying drawing：1st, coiled hair；2nd, stud；3rd, lower plane；4th, fastener hole；5th, gathering sill；6th, mistake Discharge orifice；7th, screw.

Specific embodiment

Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that advantage of the present utility model Can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to protection domain of the present utility model Define.

Accompanying drawing 1 and Fig. 2 are referred to, the utility model embodiment includes：Coiled hair 1 and stud 2；The coiled hair 1 is arranged on spiral shell One end of post 2；The middle of the coiled hair 1 offers flowing hole 6；Chamfering is provided between the upper surface and side of the coiled hair 1；Institute Lower plane 3 is offered on a pair of directions of the other end for stating stud 2；Another other side of the other end of the stud 2 opens up upwards There is gathering sill 5；A fastener hole 3 is opened up on the lower plane 3；The inside of the stud is provided with screw.

It is further that the coiled hair 1 and stud 2 are structure as a whole；

It is further that the flowing hole 6 is through hole；

It is further that the gathering sill 5 and lower plane 3 have two respectively, and symmetrical along center line respectively；

It is further, the only one of which of the fastener hole 4 that can be arranged in an arbitrary plane.

When deployed, nut links together with screw rod, and coiled hair 1 can very well protect screw rod without prejudice；Gathering sill 5 can It is oriented to screw rod, prevents screw rod to be connected deviation with stud 2；Fastener hole 4 on lower plane 3, can further reinforce spiral shell Bar is connected with stud 2；It is long when screw rod and the Connection Time of stud 2, it is difficult to when dismantling, can be poured into by flowing hole 6 Lubricating oil, reduces the friction of screw rod and stud 2.

Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every The equivalent structure or equivalent flow conversion made using the utility model description, or directly or indirectly it is used in other phases The technical field of pass, is similarly included in scope of patent protection of the present utility model.
