Abstract
The utility model discloses a screw structure, which comprises a threaded part and a screwhead. One end of the threaded part is connected with the screwhead, while the other end forms a head face; a positioning notch or a positioning lug boss is arranged on the head face of the threaded part. Through adopting a positioning tool and the positioning notch or the positioning lug boss working together, the screw structure is capable of rapidly positioning the screw structure.
Description
Affiliated technical field
The utility model relates to a kind of screw structural, relates in particular to a kind of screw structural fastening and dismounting of being convenient to.
Background technique
Usually, the supporting use of screw and screw cap is used for fastening object.When fastening object, general, just can finish fastening action with another spanner tightening the screw cap again with one behind the end of spanner retaining screw; When unloading screw, also to use identical or similar method just can finish the dismounting action equally.Otherwise if screw is not fixed, then when the rotation screw cap, screw does not have Point of Strength, thereby can only dally, and can't finish fastening or the dismounting action.
Yet, above-mentioned screw structural is with the supporting use of screw cap the time, need to vise one of screw with spanner earlier and bring in set screw, then can't fix or dismantle at concealment part, have the plate of bulk or wall to separate and just can finish the fastening of screw and dismounting by two people as the centre with spanner as an end.
The model utility content
The purpose of this utility model is to overcome the defective that the above-mentioned background technology exists, the screw structural that provides a kind of convenience to use.
For reaching above-mentioned purpose, the utility model provides a kind of screw structural, comprise a screw section and a shank, described screw section one end connects described shank, the other end forms an end face, the end face of described screw section is provided with position structure, and this position structure can be positioning recess or locating bump.
As mentioned above, the utility model screw structural is by being processed with positioning recess or being processed into locating bump on the end face of screw section, thereby can match with corresponding orientation tool in use, can easily locate this screw structural fast by orientation tool.

Embodiment
By describing technology contents of the present utility model, structure characteristics in detail, being reached purpose and effect, enumerate below that embodiment and conjunction with figs. are detailed gives explanation.
Fig. 1 has shown first embodiment of the utility model screw structural 1.In first embodiment, screw structural 1 comprises a screw section 10 and a shank 20.Described screw section 10 1 ends connect described bright 20, and the other end forms an end face 11.Described end face 11 offers one and is the square positioning recess of a word 12, and the described positioning recess 12 preferential methods of punching press that adopt form.Preferentially, the marginal existence certain distance of described positioning recess 12 and screw section 10 deforms when avoiding described screw section 10 to use.
See also Fig. 2, when with the utility model screw structural 1 and corresponding screw cap 2 supporting uses, when being used for fastening corresponding object, only need use one earlier that common screw-driver or corresponding orientation tool (figure does not show) are inserted in the described positioning recess 12, screw structural 1 is positioned and then prevents its idle running, and then use spanner to turn screw cap 2, can easily fastening fast corresponding object.Equally, when unloading screw structural 1, can adopt and realize light quick operating purpose in a like fashion.
Fig. 3 has shown second embodiment of the utility model screw structural 1.In a second embodiment, screw structural 1 is identical with first embodiment's basic structure, and difference is: end face 11 offers a positioning recess 13 triangular in shape, and the described positioning recess 13 preferential methods of punching press that adopt form.Preferentially, the marginal existence certain distance of described positioning recess 13 and screw section 10 deforms when avoiding described screw section 10 to use.When with screw structural 1 and corresponding screw cap 2 supporting uses, only need corresponding orientation tool (figure does not show) is inserted the positioning recess 13 of present embodiment, and then, can realize fastening object or unload the purpose of screw structural 1 according to the method identical with first embodiment.
Fig. 4 has shown the 3rd embodiment of the utility model screw structural 1.In the 3rd embodiment, screw structural 1 is identical with first embodiment's basic structure, and difference is: end face 11 convexes with a locating bump that is square 14.In the present embodiment, the orientation tool (figure do not show) that is used for set screw structure 1 offers and locating bump 14 corresponding locating slots.When with screw structural 1 and corresponding screw cap 2 supporting uses, locating slot by orientation tool blocks locating bump 14, screw structural 1 is positioned, and then according to the method identical, can realize fastening object or unload the purpose of screw structural 1 with first embodiment.
Fig. 5 has shown the 4th embodiment of the utility model screw structural 1.In the 4th embodiment, screw structural 1 is identical with the 3rd embodiment's basic structure, and difference is: end face 11 convexes with a locating bump 15 triangular in shape.In the present embodiment, the orientation tool (figure do not show) that is used for set screw structure 1 offers and locating bump 15 corresponding locating slots.When with screw structural 1 and corresponding screw cap 2 supporting uses, locating slot by orientation tool blocks locating bump 15, screw structural 1 is positioned, and then according to the method identical, can realize fastening object or unload the purpose of screw structural 1 with first embodiment.
In sum, the utility model screw structural 1 matches with corresponding orientation tool, thereby can easily locate this screw structural 1 fast by orientation tool by 10 end face 11 offers positioning recess or convexes with locating bump in the screw section.
In addition, the utility model is not limited to the mode that the foregoing description discloses, and the modification of other equivalence of the utility model or variation all should be encompassed in the claim scope of the present utility model.For example, positioning recess can also be quincunx or other shape; Locating bump equally also can be other shape; The quantity of positioning recess and locating bump also is not limited to one.
