Abstract
The utility model relates to a kind of self tapping swivel nuts, swivel nut ontology including hollow cylindrical, swivel nut ontology is equipped with internal screw thread, external screw thread, swivel nut ontology one end is equipped with the cut hole of cutting, there are three cut holes, and cut hole is radially opened up along swivel nut ontology, the swivel nut tooth form side of thread the same side of swivel nut ontology internal screw thread is made of the swivel nut tooth bottom side and the swivel nut crest side surfaces between crest and swivel nut tooth bottom side for being located at tooth bottom, and the angle of swivel nut tooth bottom side and swivel nut body axis is less than the angle of swivel nut crest side surfaces and swivel nut body axis.Self tapping swivel nut in use, does not need to shoot thread in advance, and can be direct screw in base material wherein to form a flank, can not only safeguard the screw thread for having already appeared routed dental phenomenon, can more save cost input.
Description
Technical field
The utility model relates to swivel nut fields, and in particular to a kind of self tapping swivel nut.
Background technique
Applying for screw has the importance pulled one hair and move the whole body in entire machinery industry.It is strong for certain contact surfaces
Lower material, such as nonferrous metal, cast iron, plastics and timber, bakelite etc. are spent, often because above-mentioned material is unbearable must
The pulling force wanted, and make screw when loading or taking-up, because the hardness of base material is inadequate, and finished product itself is caused to damage
Wound increases the expenditure and unnecessary puzzlement of dealer's cost.Many past industry producer in order to solve these problems, adopts mostly
It is handled with larger-size screw, in fact the higher cost of this mode, and operating procedure is relative complex, difficulty is big.Also
One method is installation steel-wire screw-sockets, since steel-wire screw-socket itself is spring steel wire form, are not able to satisfy high-intensitive application,
And the process for installing steel-wire screw-socket is complex, and it is inefficient.
Utility model content
It is above-mentioned to solve the problems, such as the purpose of the utility model is to provide a kind of self tapping swivel nut.
To achieve the above object, the utility model self tapping swivel nut adopts the following technical scheme that self tapping swivel nut, including hollow posts
The swivel nut ontology of shape, swivel nut ontology are equipped with internal screw thread, external screw thread, and swivel nut ontology one end is equipped with the cut hole of cutting, and cut hole has three
It is a, and cut hole is radially opened up along swivel nut ontology, the swivel nut tooth form side of thread the same side of swivel nut ontology internal screw thread is by being located at tooth
The swivel nut tooth bottom side at bottom and between crest and swivel nut tooth bottom side swivel nut crest side surfaces composition, swivel nut tooth bottom side with
The angle of swivel nut body axis is less than the angle of swivel nut crest side surfaces and swivel nut body axis.
Further, cut hole described in three is uniformly distributed along swivel nut ontology circumferencial direction.
Further, the cut hole is circular hole, and is through-hole.
Further, swivel nut tooth bottom side and the angle of swivel nut body axis are 25 degree, swivel nut crest side surfaces and swivel nut sheet
The angle of body axis is 50 degree.
Further, the swivel nut body surface is equipped with zinc coat.
The utility model has the beneficial effects that there is tooth line inside and outside the novel self tapping swivel nut, insertion plastics, aluminium alloying iron,
In the softer materials such as copper, the internal thread hole of higher-strength can be formed.Self tapping swivel nut can also repair bad internal screw thread,
Installation tool can be used directly to be screwed in the reserved particular bore of base material, for the box thread for tooth of having burst could be used that with originally
Identical screw, it is economical and beautiful, its screw strength can more be increased for new product.Three holes of self tapping swivel nut are for doing self tapping
Cutting, it can be applicable in the material of difficult cutting, cut hole can also arrange cutting material.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model self tapping swivel nut；
Fig. 2 is that the utility model self tapping swivel nut and bolt cooperate schematic diagram.
Respectively mark corresponding title: 1, swivel nut ontology in figure, 2, cut hole, 3, swivel nut tooth bottom side, 4, swivel nut crest side surfaces,
5, bolt.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art's every other embodiment obtained, all belongs to
In the range of the utility model protection.
The embodiment of the utility model self tapping swivel nut: as Figure 1-Figure 2, self tapping swivel nut, the swivel nut including hollow cylindrical
Ontology 1, swivel nut ontology 1 are equipped with internal screw thread, external screw thread.Swivel nut ontology one end is equipped with the cut hole 2 of cutting, and there are three cut holes, and
Cut hole is radially opened up along swivel nut ontology, and cut hole described in three is uniformly distributed along swivel nut ontology circumferencial direction.Cut hole is circular hole, and is logical
Hole.
There is tooth line inside and outside self tapping swivel nut, is embedded in the softer materials such as plastics, aluminium alloying iron, copper, can be formed more high-strength
The internal thread hole of degree.Self tapping swivel nut can also repair bad internal screw thread, and installation tool can be used directly and screwed in mother
In the reserved particular bore of material, the box thread for tooth of having burst could be used that and identical screw originally, it is economical and beautiful, for brand-new
Product can more increase its screw strength.
The swivel nut tooth form side of thread the same side of swivel nut ontology internal screw thread by be located at tooth bottom swivel nut tooth bottom side 3 and position
Swivel nut crest side surfaces 4 between crest and swivel nut tooth bottom side 3 form, the folder of swivel nut tooth bottom side 3 and swivel nut body axis
Angle is less than the angle of swivel nut crest side surfaces 4 and swivel nut body axis.Swivel nut tooth bottom side 3 and the angle of swivel nut body axis are 25
The angle of degree, swivel nut crest side surfaces 4 and swivel nut body axis is 50 degree.When in use, when cooperating with bolt 5, the interior spiral shell of swivel nut
The external screw thread of line and bolt 5 cooperates, the normal force and swivel nut sheet that the external screw thread touching position of swivel nut tooth bottom side 3 and bolt generates
The angle of the axis of body is 50 degree, and in no swivel nut tooth bottom side, the axis angle of swivel nut tooth form side and swivel nut ontology is only
It is 25 degree, therefore, when there is swivel nut tooth bottom side, swivel nut and the locking frictional force of bolt generated when matching are big, this makes
It is not easy to loosen.Further, the threaded hole of matrix is also provided with matrix tooth bottom side, spiral shell in swivel nut external screw thread and matrix screw thread hole
The cooperation of line is also even closer.
To prevent from corroding, swivel nut body surface is equipped with zinc coat.
The self tapping swivel nut is when in use: steps are as follows, and self tapping swivel nut is screwed in manual installation tool, cut hole downward, tool
Tip do not exceed cut hole top.By in swivel nut advances through hole, initially screw in 1 to 2 tooth away from when be confirmed whether deflection,
Otherwise it to adjust and realign.After loading, opposite direction is rotated to exit installation tool.
