Description
Technical field
The utility model relates to the field of auto parts machinery, particularly relates to a kind of positioning thread insert.
Background technique
Screw, bolt are the most frequently used fastening pieces, and it is with its low price, easy to use and be widely used.When particularly EXPANSION ANCHOR BOLTS is used in construction wall bolt, modal problem is the bolt particularly easy transfer of EXPANSION ANCHOR BOLTS, and people have thought that thousand and one way solves this problem, but is scarcely that effect is bad, and be exactly complex structure, cost is higher.
Model utility content
The technical problem that the utility model mainly solves is to provide a kind of positioning thread insert, swivel nut body upper-end surface is the arc groove face be oppositely arranged, the radian in arc groove face is 22-45 °, and structure is simple, easy to manufacture, cost is low, easy to use, good antiskid effect, can make the positioning thread insert of bolt not transfer.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: provide a kind of positioning thread insert, comprise the swivel nut body with circular central through hole, the surrounding inwall of described central through bore is provided with screw thread, described swivel nut body lower end surface is horizontal plane, described swivel nut body upper-end surface is the arc groove face be oppositely arranged, and the radian in described arc groove face is 22-45 °.
In the utility model preferred embodiment, described swivel nut body is round structure.
In the utility model preferred embodiment, the outer diameter of described swivel nut body is 30 ± 0.5mm.
In the utility model preferred embodiment, described central through bore diameter is 18 ± 0.5mm.
In the utility model preferred embodiment, described positioning thread insert adopts metallic material, and described metallic material is the one in powder metallurgy, carbon steel, stainless steel or cast steel.
In the utility model preferred embodiment, described positioning thread insert adopts integrated formed structure.
The beneficial effects of the utility model are: positioning thread insert of the present utility model, swivel nut body upper-end surface is the arc groove face be oppositely arranged, the radian in arc groove face is 22-45 °, and structure is simple, easy to manufacture, cost is low, easy to use, good antiskid effect, can make the positioning thread insert of bolt not transfer.
Accompanying drawing explanation
In order to be illustrated more clearly in the technological scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings, wherein:
Fig. 1 is the sectional view of a preferred embodiment of the utility model positioning thread insert;
Reference character is as follows: 1, swivel nut body, and 2, central through bore, 11, horizontal plane, 12, arc groove face.
Embodiment
Be clearly and completely described to the technological scheme in the utility model embodiment below, obviously, described embodiment is only a part of embodiment of the present utility model, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making other embodiments all obtained under creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1, the utility model embodiment comprises:
A kind of positioning thread insert, comprise the swivel nut body 1 with circular central through hole 2, the surrounding inwall of described central through bore 2 is provided with screw thread (figure does not look), described swivel nut body lower end surface is horizontal plane 11, described swivel nut body upper-end surface is the arc groove face 12 be oppositely arranged, and the radian in described arc groove face 12 is 22-45 °.Wherein, described central through bore diameter is 18 ± 0.5mm.
In above-mentioned, described swivel nut body 1 is round structure.Wherein, the outer diameter of described swivel nut body 1 is 30 ± 0.5mm.
Further, described positioning thread insert adopts integrated formed structure, and structure is simple, easy to manufacture, cost is low, easy to use, because swivel nut body upper-end surface is the arc groove face 12 be oppositely arranged, so bolt not transfer can be made after connecting bolt, good antiskid effect.
In the utility model, described positioning thread insert adopts metallic material, and described metallic material is the one in powder metallurgy, carbon steel, stainless steel or cast steel.
In sum, the positioning thread insert that the utility model discloses, swivel nut body 1 upper-end surface is the arc groove face 12 be oppositely arranged, and the radian in arc groove face 12 is 22-45 °, and structure is simple, easy to manufacture, cost is low, easy to use, good antiskid effect, can make the positioning thread insert of bolt not transfer.
The foregoing is only embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
