Abstract
The utility model discloses a kind of screws with two sections of screw threads, including nut, and the screw rod being connect with the nut, the screw further include：The screw rod includes the interior bar for being connect with the nut, and the external thread part for being connect with external connection screw；The lower face of the nut is installed with the groove of an annular around the interior bar border, and internal thread part is provided on the side wall of the groove.Screw described in the utility model can be divided into two sections and is threadedly coupled with the external world, and what can more be fastened is threadedly coupled with the external world, avoids stripped thread, and prevent take up exceptional space.
Description
Technical field
The utility model is related to a kind of screw more particularly to a kind of screws with two sections of screw threads.
Background technology
Screw is widely used general as a kind of common fastener.But the stripped thread of screw is that it is caused normally to make
One larger defect.
Therefore, the prior art could be improved and improve.
Utility model content
Place in view of above-mentioned deficiencies of the prior art having two sections of screw threads the purpose of this utility model is to provide a kind of
Screw, it is intended to avoid the stripped thread of screw.
In order to achieve the above object, the utility model takes following technical scheme：
A kind of screw with two sections of screw threads, including nut, and the screw rod that is connect with the nut, the screw also wrap
It includes：
The screw rod includes the interior bar for being connect with the nut, and the external thread part for being connect with external connection screw；
The lower face of the nut is installed with the groove of an annular around the interior bar border, on the side wall of the groove
It is provided with internal thread part.
Preferably, the external thread part is identical as the rotation direction of internal thread part.
Preferably, the interior bar is higher than the groove.
Preferably, the nut, screw rod integrally connected.
Preferably, the lateral wall of the nut is oppositely arranged the plane for being useful for rotating the screw.
Compared with prior art, the beneficial effects of the utility model：Screw described in the utility model is special screw,
It need to be used cooperatively with extraneous threaded portion, extraneous threaded portion includes an internal thread hole, and the upper surface of the internal thread hole is provided with
The lateral wall of the protruding block of one annular, the protruding block is provided with outside compatible with the internal thread part on the utility model nut
Screw thread；Screw described in the utility model is threadedly coupled by the external thread part on screw rod with extraneous internal thread hole, the spiral shell
Internal thread part on cap is then threadedly coupled with extraneous protruding block, to make connection more fasten, avoids stripped thread.
Description of the drawings
Fig. 1 is a kind of structural schematic diagram of the screw preferred embodiment with two sections of screw threads of the utility model.
Specific implementation mode
To keep the purpose of this utility model, technical solution and effect clearer, clear, develop simultaneously implementation referring to the drawings
The utility model is further described in example.It should be appreciated that specific embodiment described herein is only explaining this practicality
It is novel, it is not used to limit the utility model.
A kind of screw with two sections of screw threads provided by the utility model, refers to Fig. 1, as shown, include nut 20,
And the screw rod 10 being connect with the nut 20, the screw further include：
The screw rod 10 includes the interior bar 12 for being connect with the nut 20, and the outer spiral shell for being connect with external connection screw
Line portion 11；
The lower face of the nut 20 is installed with the groove of an annular around 12 border of the interior bar（It does not mark）, described
Internal thread part 21 is provided on the side wall of groove.
In the utility model embodiment, by the lower face of the nut 20（I.e. close to the end face of the screw rod 10）
Groove is opened up around the interior bar 12, which is provided with the internal thread being connect with the external world, to make the present embodiment and the external world two
When section connection, not additional occupied space；External thread part 11 on the screw rod 10 is threadedly coupled with the external world, the nut 20
On internal thread part 21 is equally threadedly coupled with the external world, to make the screw in the present embodiment more be fastened with extraneous connect, and
It can avoid stripped thread.In the present embodiment, the screw is special screw, need to be used cooperatively with extraneous threaded portion, extraneous screw thread
Portion includes an internal thread hole, and the upper surface of the internal thread hole is provided with the protruding block of an annular, and the lateral wall of the protruding block is set
It is equipped with external screw thread compatible with the internal thread part on the utility model nut.
In addition, in the present embodiment, the screw can also be used for connecting without influencing its use with general internal thread hole.
Further, the external thread part 11 is identical as the rotation direction of internal thread part 21.
Further, the interior bar 12 is higher than the groove.
Further, the nut 20,10 integrally connected of screw rod.
Further, the lateral wall of the nut 20 is oppositely arranged the plane 22 for being useful for rotating the screw.
In conclusion the utility model discloses a kind of screw with two sections of screw threads, including nut, and with the nut
The screw rod of connection, the screw further include：The screw rod includes the interior bar for being connect with the nut, and is used for and external spiral shell
The external thread part of line connection；The lower face of the nut is installed with the groove of an annular around the interior bar border, described recessed
It is provided with internal thread part on the side wall of slot.Screw described in the utility model can be divided into two sections and is threadedly coupled with the external world, can be more
Being threadedly coupled with the external world for fastening, avoids stripped thread, and prevent take up exceptional space.
It is understood that for those of ordinary skills, can with technical solution according to the present utility model and
The design of its utility model is subject to equivalent substitution or change, and all these changes or replacement should all belong to appended by the utility model
Scope of the claims.
