Abstract
The invention discloses a detachable screw. The detachable screw comprises a double-screw bolt and a screw cap which are of a split structure. A cross groove is formed in the screw cap. The double-screw bolt and the screw cap are in threaded connection. A threaded segment is arranged at the upper end of a threaded rod. A threaded hole is formed in corresponding portion in the middle of the screw cap. The threaded segment is screwed into the threaded hole so that threaded connection can be achieved. An anti-slip groove is formed in the peripheral face of the screw cap and surrounds the whole screw cap by a circle. When the detachable screw is used, the screw cap and the double-screw bolt are installed together, then the screw cap and the double-screw bolt are screwed into a screw installing hole, after installation is completed, the screw cap is screwed out of the double-screw bolt, and therefore the screw cap and the double-screw bolt can be separated, and the requirements of some special using occasions are met.
Description
Technical field
The present invention relates to a kind of screw, particularly relate to a kind of dismountable screw.
Background technique
Screw is the fastening piece for mounting article, and it uses comparatively extensive, usually screw is mounted to fixation and with in the screw of fixture articles, just can implements to fix.Spun by screw thread between screw and screw.But present screw is all-in-one-piece structure, can not dismantle between screw rod and nut, the use occasion that some is special can not be met.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, providing a kind of dismountable screw.
The present invention is achieved through the following technical solutions:
A kind of dismountable screw, comprise stud, nut, described stud and nut are split-type structural, described nut offers cross recess, be threaded connection between described stud and nut, be provided with thread section in the upper end of screw rod, the neutral position of corresponding nut has tapped hole, and thread section screws in tapped hole and realizes being threaded.
As the preferred technical solution of the present invention, the periphery of described nut is provided with antiskid groove.
As the preferred technical solution of the present invention, described groove was around whole nut one week.
As the preferred technical solution of the present invention, described stud and nut adopt same material to make.
Compared with prior art, the invention has the beneficial effects as follows: nut and stud in use, are installed together by the present invention, then screw in screw mounting hole, after installation, nut is screwed out from stud, thus realize being separated of nut and stud, meet the use occasion that some is special.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure: 1 ?stud; 2-nut; 3-cross recess; 4-screw thread.
Embodiment
In order to make object of the present invention, technological scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is structural representation of the present invention.
The dismountable screw of described one, comprises stud 1, nut 2, and described stud 1 adopts same material to make with nut 2.Described stud 1 is split-type structural with nut 2, described nut 2 offers cross recess 3, and described stud 1 is connected by screw thread 4 with between nut 2, is provided with thread section in the upper end of screw rod 1, the neutral position of corresponding nut 2 has tapped hole, and thread section screws in tapped hole and realizes being threaded.
The periphery of described nut 2 is provided with antiskid groove 5, and described groove 5 was around whole nut 2 one weeks.
Nut and stud in use, are installed together by the present invention, then screw in screw mounting hole, after installation, are screwed out by nut from stud, thus realize being separated of nut and stud, meet the use occasion that some is special.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
