Description
Technical field
The utility model relates to fastening connection piece technical field, particularly relates to a kind of easily stubborn bolt.
Background technique
Nonstandard bolt used on the market at present, can be cylindric because of bolt column in use, and the aperture of bolt hole does not have chamfering and aperture is equal to bolt external diameter, the very large power of expense is needed to go to aim at, when screwing force is excessive, connecting thread easily weares and teares, and makes to connect unstable and working life is short.
Model utility content
The purpose of this utility model is to provide a kind of and easily twists bolt, and its structure is simple, easily manufactured, have conveniently to connect, convenient lubrication, long service life and the feature of multiple tightening way.
In order to achieve the above object, the technical solution of the utility model is:
A kind of easily stubborn bolt, comprises cylindroid, described cylindroid is provided with conical column, described conical column is provided with guide cone, described guide cone offers arc angle; Described cylindroid offers annular knurl, described conical column offers connecting thread, described guide cone offers guide thread; Described cylindroid also offers cross recess.
Further: described conical column offers oil groove.
Further: between described oil groove and conical column, offer oil duct groove.
Described cylindroid, conical column, guide cone are integrally manufactured to be formed.
The beneficial effects of the utility model are: its structure of the utility model is simple, easily manufactured, have conveniently to connect, convenient lubrication, long service life and the feature of multiple tightening way.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment 1
One as shown in Figure 1 easily twists bolt, comprise cylindroid 1, avoid the defect because frictional force causes screwing force can not make not, described cylindroid 1 is provided with conical column 2, is convenient to connect, described conical column 2 is provided with guide cone 3, be convenient to automatically to adjust attachment hole consistent with the axle center of conical column, described guide cone 3 offers arc angle 4, eliminates stress concentrated, prevent from reducing working life because of guide cone wearing and tearing; Described cylindroid 1 offers annular knurl 5, increases frictional force, be convenient to tighten, described conical column 2 offers connecting thread 6, described guide cone 3 offers guide thread 7; Described cylindroid 1 also offers cross recess 8, and when tightening, also available cross driver is tightened.
Further: described conical column 2 offers oil groove 9, lubricant oil easy to use.
Further: offer oil duct groove 10 between described oil groove 9 and conical column 2, scattering of lubricant oil can be facilitated, make lubrication effect better.
Described cylindroid 1, conical column 2, guide cone 3 is integrally manufactured forms.
The one of the present embodiment easily twists bolt, and its structure is simple, easily manufactured, have conveniently to connect, convenient lubrication, long service life and the feature of multiple tightening way.
