Abstract
The utility model relates to a fastener, in particular to a screw, which comprises a screw body provided with a screw cap at one end, and is characterized in that the screw body comprises knurled straight teeth and a threaded rod, wherein one ends of the knurled straight teeth are connected with the screw cap; and the threaded rod is connected with the other ends of the knurled straight teeth. According to the screw, the knurled straight teeth are designed, so that the screw is accurate and stable in transmission and high in mechanical efficiency; and the objects can also be fastened together excellently by the threaded rod, so that the screw has the advantages of rational structural design, long service life and safe and reliable working.
Description
Technical field
The utility model relates to a kind of fastening piece, relates 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 the daily life: such 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.; Then use large-scale screw, nut as for engineering, building, bridge; Traffic tool, aircraft, electric car, automobile etc. then are large primary screw and use.And existing screw can't accurately be controlled the distance that screw enters object in being screwed into process, then can damage object, causes user's loss.
The model utility content
The utility model is in order to solve the problems of the technologies described above, a kind of screw to be provided, and its reasonable in design can well be controlled the distance that screw enters object, and transmission accurately, steadily, mechanical efficiency is high.
To achieve these goals, the utility model can be taked following technological scheme:
A kind of screw, it comprises that an 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 that is connected with the described annular knurl straight-tooth the other end of an end connecting screw cap.
As preferred implementation of the present utility model, screw comprises that further the external diameter of described annular knurl straight-tooth is greater than the up and down thread spacing of described threaded stem.
As preferred implementation of the present utility model, screw comprises that further described annular knurl straight-tooth and described screw cap spacing are 0 ~ 1.5mm.
As preferred implementation of the present utility model, screw comprises that further angle is acute angle between the upper thread face of described threaded stem and lower thread face.
As preferred implementation of the present utility model, screw comprises that further angle is 45 ° between the upper thread face of described threaded stem and lower thread face.
As preferred implementation of the present utility model, screw comprises that further the shape of described screw cap is the square that is provided with eight chamferings.The beneficial effects of the utility model are: screw of the present utility model, compared with prior art, between screw cap and threaded stem, be provided with the annular knurl straight-tooth, 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.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing relevant of the present utility model in the following describes only is embodiments more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plan view of preferred embodiment of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is the enlarged view of A among Fig. 2.
Embodiment
Below with reference to each embodiment shown in the drawings the utility model is described in detail.But these embodiments do not limit the utility model, and the conversion on the structure that those of ordinary skill in the art makes according to these embodiments, method or the function all is included in the protection domain of the present utility model.
Preferred embodiment: such as Fig. 1, Fig. 2, shown in Figure 3, comprise that an 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 that is connected with described annular knurl straight-tooth 2 the other ends of an end connecting screw cap 1.
Wherein, the external diameter of described annular knurl straight-tooth 2 is greater than the up and down thread spacing of described threaded stem 3, and convenient the observation simultaneously, also increased the steadiness of screw.
Concrete, described annular knurl straight-tooth 2 and described screw cap 1 spacing are saved cost less than 1.5mm, simultaneously, also fully improve 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 the 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, and is attractive in appearance and easy to process.
The screw of this preferred embodiment is when being screwed into object, because annular knurl straight-tooth 2 has advantages of that transmission is accurate, steady, mechanical efficiency is high, so that screw is 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 be not that each mode of execution only comprises an independently technological scheme, this narrating mode of specification only is for clarity sake, those skilled in the art should make specification as a whole, technological scheme in each mode of execution also can through appropriate combination, form other mode of executions that it will be appreciated by those skilled in the art that.
Above listed a series of detailed description only is specifying for feasibility mode of execution of the present utility model; they are not to limit protection domain of the present utility model, allly do not break away from equivalent mode of execution or the change that the utility model skill spirit does and all should be included within the protection domain of the present utility model.
