It is one such structure.Including the first connector made of metal, wherein the first connector is at least in the whole of the first component
The first component is penetrated on a thickness, in the end of the first connector towards second component, the first connector is welded to second
Part is welded to the second connector made of metal for penetrating second component.The structure second component can be inserted there are one needing
Enter the space of the first component, the side of not applicable second component and the side of the first component are rotatably connected.In addition, the structure needs
It welds, not only mounting process is complicated, and is difficult to demolition and maintenance.
Utility model content
Just in order to solve metalwork in the prior art and nonmetal parts need grafting after be rotatably connected, mounting process is multiple
Miscellaneous, and the technical issues of be difficult to demolition and maintenance, it is simple that the utility model provides a kind of installation, the convenient metalwork of demolition and maintenance
With nonmetal parts side Rotatable connecting structure.
The technical solution of the utility model is：A kind of Rotatable connecting structure, including the first connector and the second connector,
Second connector is equipped with rotating hole, and rotating hole is socketed with rotary lubrication bushing, and the first connector is equipped with connecting hole, connecting hole socket
There are outside stationary bushing, outside stationary bushing to be threaded with fixing screws, rotary lubrication bushing is socketed with fixing screws side wall.
First connector is nonmetallic, and the second connector is metal, and two connector sides are rotatably connected, and installation is simple, dismounting dimension
Shield is convenient.
Preferably, the first connector end is connected with inside stationary bushing, inside stationary bushing section is at П shapes, lower part
With connecting hole grafting, top is adjacent to the first connector end face；Nonmetal parts end face is protected, will not be worn.
Preferably, fixing screws are fillister head screw, socket cap side wall is stepped, and recessed arc surface is small column
Body side surface；Screw not only plays the role of fastening locking, but also plays the role of connecting shaft, reduces element, compact-sized, cost-effective.
Preferably, rotary lubrication bushing is cylindrical shape, madial wall is socketed with small cylinder side, and lateral surface is equipped with recessed
Slot, groove are rotatably connected with rotating hole, and upper surface is adjacent to fixing screws cylinder lower surface, lower surface and inside stationary bushing
Upper surface is adjacent to；Both fixing screws side had been protected, will not have been worn, and has played the role of locking to fixing screws, it is simple and reasonable,
It is easily manufactured.
Compared with prior art, the utility model has the beneficial effects that：First connector is nonmetallic, and the second connector is
Metal, two connector sides are rotatably connected, and installation is simple, and demolition and maintenance are convenient, save maintenance cost.It is few using element,
Compact-sized, small, use scope is wide.Simple and reasonable, manufacturing cost is low.
Description of the drawings
Attached drawing 1 is the utility model section view.
In figure：The first connectors of 1-；The second connectors of 2-；3- rotary lubrication bushings；Stationary bushing on the inside of 4-；It is solid on the outside of 5-
Determine bushing；6- fixing screws；61- small cylinders side.
Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment 1：
As shown in Figure 1, a kind of Rotatable connecting structure.Including the first connector 1, the second connector 2, rotary lubrication bushing
3, inside stationary bushing 4, outside stationary bushing 5 and fixing screws 6.First connector 1 is nonmetal structure.First connector 1
Equipped with connecting hole, connecting hole penetrates through upper and lower surface.Connecting hole is formed by connecting by the hole of upper, middle and lower three, and section is at " work " shape.It is interior
Stationary bushing 4 section in side is at П shapes.The lower part of inside stationary bushing 4 is inserted into connecting hole top circular hole and is fixed.Inside stationary bushing 4
Top is adjacent to 1 top circular hole end face of the first connector.Outside stationary bushing 5 is T-shaped.5 small cylinder of outside stationary bushing with
Connecting hole interstitial hole is fixed.5 big cylinder upper surface of outside stationary bushing and the upper surface of connecting hole bottom hole are adjacent to.Outside is solid
Determine bushing 5 and is equipped with internal thread.Fixing screws 6 are fillister head screw.6 socket cap side wall of fixing screws is stepped, section at
" " shape.The recessed arc surface of 6 socket cap of fixing screws is small cylinder side 61.The external screw thread of fixing screws 6 is solid with outside
Determine the internal thread engagement of bushing 5.Rotary lubrication bushing 3 is cylindrical shape.3 madial wall of rotary lubrication bushing and small cylinder side 61
It is adjacent to.The lateral surface of rotary lubrication bushing 3 is equipped with groove.3 section of rotary lubrication bushing is at " Contraband " shape.On rotary lubrication bushing 3
Surface is adjacent to 6 cylinder lower surface of fixing screws.3 lower surface of rotary lubrication bushing is adjacent to 4 upper surface of inside stationary bushing.
Second connector 2 is metal structure.Second connector 2 is equipped with rotating hole, and rotating hole penetrates through upper and lower surface.Rotary lubrication bushing 3
The groove of lateral surface and rotating hole clearance fit.
When installation, now inside stationary bushing 4 and outside stationary bushing 5 are inserted into respectively and the connecting hole of the first connector 1
Both ends.The lateral surface groove of rotary lubrication bushing 3 is connect with the rotating hole of the second connector 2.Fixing screws 6 are passed through into rotation
Lubricating bushings 3, inside stationary bushing 4 are threadedly coupled with outside stationary bushing 5.When tightening 6 screw thread of fixing screws, due to rotation
Lubricating bushings 3 have elasticity, and be locked screw 6, and the rotation of the second connector 2 will not loosen.The rotation abrasion of second connector 2
