Abstract
The invention relates to a faster, in particular to a screw. The screw comprises a screw body with one end provided with a nut and is characterized in that the screw body comprises knurl straight teeth and a threaded rod, wherein one end of each knurl straight tooth is connected with the nut and the threaded rod is connected with the other end of each knurl straight tooth. According the screw, the knurl straight teeth are arranged, so that transmission is accurate and stable, the mechanical efficiency is high, articles can be well fastened together through the threaded rod, the structural design is reasonable, the service life is long, and work is safe and reliable.
Description
Technical field
The present invention relates to a kind of fastening piece, relate in particular to a kind of screw.
Background technique
Screw is the general saying of fastening piece, daily pet phrase.Screw is industrial necessity indispensable in daily life: as the minimum screw of the uses such as photographic camera, glasses, clock and watch, electronics; Screw as one of TV, electric product, musical instrument, furniture etc.; As for engineering, building, bridge, use large-scale screw, nut; Traffic tool, aircraft, electric car, automobile etc. are large primary screw and use.And existing screw cannot accurately be controlled the distance that screw enters object in being screwed into process, then can damage object, cause user's loss.
The object of invention
The present invention is in order to solve the problems of the technologies described above, and a kind of screw is provided, and its reasonable in design can well be controlled the distance that screw enters object, and transmission is accurate, steady, mechanical efficiency is high.
To achieve these goals, the present invention can take following technological scheme:
, it comprises that one end is provided with the screw body of screw cap, it is characterized in that, described screw body comprises the annular knurl straight-tooth and the threaded stem being connected with the described annular knurl straight-tooth the other end of one end connecting screw cap.
As the preferred embodiment of the present invention, screw further comprises that the external diameter of described annular knurl straight-tooth is greater than the spacing of thread up and down of described threaded stem.
As the preferred embodiment of the present invention, screw further comprises that described annular knurl straight-tooth and described screw cap spacing are 0 ~ 1.5mm.
As the preferred embodiment of the present invention, screw further comprises that between the upper thread face of described threaded stem and lower thread face, angle is acute angle.
As the preferred embodiment of the present invention, screw further comprises that between the upper thread face of described threaded stem and lower thread face, angle is 45 °.
As the preferred embodiment of the present invention, screw further comprises that the shape of described screw cap is the square that is provided with eight chamferings.The invention has the beneficial effects as follows: screw of the present invention compared with prior art, is provided with annular knurl straight-tooth between screw cap and threaded stem, can not only well object be tightened together, and transmission is accurate, steady, mechanical efficiency is high, its reasonable in design, long service life, safe and reliable.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technological scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing relevant of the present invention in the following describes is only some embodiments of the present invention, for those of ordinary skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plan view of the preferred embodiments of the present invention;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the enlarged view of A in Fig. 2.
Embodiment
Below with reference to each embodiment shown in the drawings, describe the present invention.But these embodiments do not limit the present invention, the conversion in the structure that those of ordinary skill in the art makes according to these embodiments, method or function is all included in protection scope of the present invention.
Preferred embodiment: as shown in Figure 1, Figure 2, Figure 3 shows, comprise that one end is provided with the screw body of screw cap 1, described screw body comprises the annular knurl straight-tooth 2 and the threaded stem 3 being connected with described annular knurl straight-tooth 2 the other ends of one end connecting screw cap 1.
Wherein, the external diameter of described annular knurl straight-tooth 2 is greater than the spacing of thread up and down of described threaded stem 3, and convenient observation, meanwhile, has also increased the steadiness of screw.
Concrete, described annular knurl straight-tooth 2 is less than 1.5mm with described screw cap 1 spacing, cost-saving, meanwhile, also fully improves the utilization ratio of screw.
Wherein, the upper thread face 31 of described threaded stem 3 and 32 angles of lower thread face are 45 °, can better with corollary equipment transmission, and thread transmission, also reduces greatly to the spoilage of object.
Concrete, the shape of described screw cap 1 is the square that is provided with eight chamferings, attractive in appearance and easy to process.
The screw of this preferred embodiment, when being screwed into object, because annular knurl straight-tooth 2 has advantages of that transmission is accurate, steady, mechanical efficiency is high, makes screw safe and reliable when work, and long service life.
Be to be understood that, although this specification is described according to mode of execution, but not each mode of execution only comprises an independently technological scheme, this narrating mode of specification is only for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can, through appropriately combined, form other mode of executions that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility mode of execution of the present invention; they are not in order to limit the scope of the invention, all disengaging within equivalent mode of execution that skill spirit of the present invention does or change all should be included in protection scope of the present invention.
