Abstract
A kind of screw described in the utility model, described screw comprises screw body and nut, and described nut is provided with straight groove or the cross recess that coordinates screw-driver, and the maximum edge of described nut is surrounded by two sections of symmetrical arc-shaped edges and two sections of symmetrical straight lines.Non-circular design by nut, makes in the situation that there is no screw-driver, can clamp nut with pliers and be rotated, installation for convenience detach.
Description
Technical field
The utility model relates to a kind of fixed block, especially a kind of screw.
Background technique
Screw is common in machinery, and electrical equipment and building etc., be generally metal manufacture, cylindrical, and irregular ditch is carved on surface, as a plane of inclination around screw side, allows screw can tightly lock outstanding screw cap or other objects.The top diameter of screw is larger, can be rounded or etc. Hexagon, allow instrument as screwdriver or the rotatable screw of spanner.Compared with outstanding top, also make screw can drilledly too deeply not pass material, and improve the pressure of screw to material.
Screw comprises screw body and nut, described nut is provided with straight groove or the cross recess that coordinates screw-driver, the nut of existing screw is all circular, existing nut can only be applicable to screw-driver reverses, cause Applicable scope little, do not having in screw-driver situation, be difficult to realize and reverse, using inconvenient.
Model utility content
Problem to be solved in the utility model is to improve screw in background technique to exist screw to exist nut can only be applicable to the problem that screw-driver reverses.
In order to overcome the above problems, the utility model provides a kind of screw, described screw comprises screw body and nut, described nut is provided with straight groove or the cross recess that coordinates screw-driver, the maximum edge of described nut is surrounded by two sections of symmetrical arc-shaped edges and two sections of symmetrical straight lines, described nut is provided with the person's cross recess that coordinates screw-driver, one of them straight trough of described cross recessed runs through nut, described screw body comprises and the screw top of nut one and the screw bottom that removably connects with screw top, the equal diameters of described screw top and screw bottom, one end of described screw bottom is provided with counterbore, described counterbore inwall is provided with internal thread, the bottom on described screw top is provided with the outside thread matching with internal thread.
A kind of screw described in the utility model, described screw comprises screw body and nut, and described nut is provided with straight groove or the cross recess that coordinates screw-driver, and the maximum edge of described nut is surrounded by two sections of symmetrical arc-shaped edges and two sections of symmetrical straight lines.Non-circular design by nut, makes in the situation that there is no screw-driver, can clamp nut with pliers and be rotated, installation for convenience detach.
Accompanying drawing explanation
Accompanying drawing 1 is the nut schematic diagram of screw of the present utility model
Accompanying drawing 2 is generalized sections of screw described in the utility model
1, nut; 2, screw top; 21, boss; 3, screw bottom; 31, counterbore; 4, arc-shaped edges; 5, straight line.
Embodiment
Below in conjunction with accompanying drawing, a kind of screw of the utility model is described further.
As shown in Figure 1, the screw of the present embodiment, screw comprises screw body and nut 1, and nut 1 is provided with straight groove or the cross recess that coordinates screw-driver, and the maximum edge of nut 1 is surrounded by two sections of symmetrical arc-shaped edges 4 and two sections of symmetrical straight lines 5.Non-circular design by nut 1, makes in the situation that there is no screw-driver, can clamp nut 1 with pliers and be rotated, installation for convenience detach.
Originally be in example, described nut 1 is provided with the person's cross recess that coordinates screw-driver, and one of them straight trough of cross recessed runs through nut 1.Make screw both go for straight screwdriver, go for again Phillips screwdriver.
Originally be in example, described screw body comprises and the screw top 2 of nut 1 one and the screw bottom 3 that removably connects with screw top 2, the equal diameters of screw top 2 and screw bottom 3, screw top 2 and screw bottom 3 removably connect by screw thread, one end of screw bottom 3 is provided with counterbore 31, counterbore 31 inwalls are provided with internal thread, and the bottom on screw top 2 is provided with the outside thread matching with internal thread.By screw-thread fit, this technological scheme makes screw body (screw foot) length adjustable, and convenient and different occasions is used.
The utility model is not limited to above embodiment and conversion.
