The problem of the purpose of the present invention is to solve background techniques, and a kind of structure proposed is simply, conveniently
Practical bidirectional helical is swollen hoop connector.
To achieve the above object, the technical scheme adopted by the invention is that:
Bidirectional helical is swollen hoop connector, the bidirectional helical set including circular tube shaped, the interior spiral shell of setting in the hole of the bidirectional helical set
Line, a stomidium of the bidirectional helical set is interior to be arranged left screw rod, the right screw rod of setting in another stomidium, the bidirectional helical set and a left side
Screw rod is cooperated by left hand thread engagement, with right screw rod by right-handed thread.
A further improvement of the present invention is that: undercut, the left spiral shell are provided among the inner hole of the bidirectional helical set
The corresponding inclined-plane that can be covered by screw thread swelling bidirectional helical after the setting fitting of the end of bar and the right screw rod, it is described double
It is greater than the chamfer length of left screw rod and right screw rod to the length of the undercut of thread bush.
A further improvement of the present invention is that: it is provided on the excircle of the bidirectional helical set for rotating bidirectional helical
The flat horizontal surface of set.
A further improvement of the present invention is that: the flat horizontal surface has 2 or 4, is evenly arranged on the excircle of bidirectional helical set
On.
A further improvement of the present invention is that: it is fixedly installed on the excircle of the bidirectional helical set two-way for rotating
The shift fork of thread bush.
A further improvement of the present invention is that: the shift fork is provided with 2~4, is evenly arranged on the excircle of bidirectional helical set
On.
A further improvement of the present invention is that: the left screw rod and the right screw rod are hollow tubular structure.
By adopting the above-described technical solution, the technological progress achieved by the present invention is:
It is the configuration of the present invention is simple, convenient and practical, as a kind of connector, it can be applied to more extensive field.In engineering
In machinery, it is mainly used for a part and needs to split into two-section, wherein two-section can replace different structure and size etc., with
Expand the application range of part, reduces use cost.
The screw thread of two kinds of setting different rotation directions, connects the screw rod at both ends in bidirectional helical sets of holes, can rotate two-way spiral shell
When line covers, two screw rods itself do not have to rotation and can while move axially in opposite directions, ensure that the determination of two screw rod installation directions
Property.
Undercut is provided among the inner hole of bidirectional helical set, the end setting of left screw rod and right screw rod is corresponding tiltedly
Face can be such that bidirectional helical covers in rundown process, and the inclined-plane of left screw rod and right screw rod gradually interlocks, until when fitting, as
Tight condition；Inclined-plane is arranged in the end of left screw rod and right screw rod, can also cover more more stubborn tighter, bidirectional helical set with bidirectional helical
The left screw rod that can be intermeshed by inclined-plane and right screw rod swelling, prevent thread looseness；The length of the undercut of bidirectional helical set is big
In the chamfer length of left screw rod and right screw rod, with to avoid in rundown process, the inclined-plane of left screw rod and right screw rod intermeshes
When, the internal screw thread and left screw rod of bidirectional helical set or the external screw thread of right screw rod are interfered.
It is provided with flat horizontal surface on the excircle of bidirectional helical set, flat horizontal surface there are 2 or 4, is evenly arranged on bidirectional helical set
On excircle, for placing the tools such as spanner to rotate bidirectional helical set.
Shift fork is fixedly installed on the excircle of bidirectional helical set, shift fork is provided with 2~4, is evenly arranged on bidirectional helical set
On excircle, for rotating bidirectional helical set.
Left screw rod and right screw rod are hollow tubular structure, can mitigate weight.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of first embodiment of the invention；
Fig. 2 is the A-A sectional view of Fig. 1；
Fig. 3 is the structural schematic diagram of second embodiment of the invention.
Wherein: 1, left screw rod 2, bidirectional helical cover 3, right screw rod 4, shift fork.
Specific embodiment
The present invention is described in further details with reference to the accompanying drawings and examples:
Embodiment 1
Bidirectional helical is swollen hoop connector, as shown in Figure 1 and Figure 2, the bidirectional helical set 2 including circular tube shaped, bidirectional helical set 2
Flat horizontal surface is provided on excircle, flat horizontal surface is provided with 2, and perhaps 42 flat horizontal surfaces or 4 flat horizontal surfaces are evenly distributed on
On the excircle of bidirectional helical set 2；Internal screw thread is set in the hole of bidirectional helical set 2, undercut is set among screw hole；Bidirectional helical
Inclined-plane is arranged in the left screw rod 1 of setting in one stomidium of set 2, the end of left screw rod 1, and bidirectional helical set 2 passes through left-handed spiral shell with left screw rod 1
Line cooperation；The right screw rod 3 of setting in another stomidium of bidirectional helical set 2, the inclined-plane phase of the end setting and left screw rod 1 of right screw rod 3
