Description
Technical field
The utility model relates to mechanical field, more specifically to a kind of screw connection set.
Background technique
In mechanical field, screw plays an important role as each parts connector, in some mechanical devices, tend to occur that screw length falls short of or the length of some axle falls short of, much all adopt in this case the mode of welding to connect one end screw rod or axle, but in use have larger pulling force or torsion generation for screw and axle, be easy to cause weld fracture, larger on equipment and device impact.
Summary of the invention
The purpose of this utility model is to provide a kind of screw connection set, adopts this device that two screws or axle are linked together, and can increase the length of screw or some axles.For achieving the above object, the utility model has adopted following technological scheme:
A kind of screw connection set, comprises screw, the first connector, the second connector, intermediate connector, and described the first connector becomes cylindrical, to downward-extension two side, circular hole is all set on two side in bottom surface; Penetration hole is offered in the first connector inside, and penetration hole is made up of upper and lower two-part, and upper part penetration hole diameter is less than lower part penetration hole diameter; The second described connector becomes cylindrical, and end face upwards extends two side, and circular hole is all set on two side, and the second connector upwards arranges screw by bottom; Described intermediate connector is four prism type, and intermediate connector is offered penetration hole on corresponding side between two; Described screw is made up of nut and screw rod; Described screw is through the penetration hole of the first connector, and nut is stuck in the first connector bottom penetration hole, and the first connector uses head rod and the second connecting rod to be connected with the second connector by intermediate connector.
It is polygon-shaped that described screw nut can be arranged to sectional shape, and the shape and size of nut shape and size and the first connector bottom penetration hole match.
Described head rod passed the circular hole on circular hole, intermediate connector top penetration hole and another sidewall of the first connector on the first connector sidewall successively, blocked by clip.
The second described connecting rod passed the circular hole on circular hole, intermediate connector bottom penetration hole and another sidewall of the second connector on the second connector sidewall successively, blocked by clip.
Screwhole diameter and the screw screw diameter of the second connector bottom are coupled.
The utlity model has following advantage: can firmly two screws or axle be connected together, device firmly, simple in structure.

Embodiment
With the drawings and specific embodiments, the utility model is described in further detail below.
As shown in the figure, a kind of screw connection set, comprises screw 1, the first connector 2, the second connector 4, intermediate connector 11, and 2 one-tenth of described the first connectors are cylindrical, to downward-extension two side 9, circular hole are all set on two side in bottom surface; Penetration hole 8 is offered in the first connector 2 inside, and penetration hole is made up of upper and lower two-part, and upper part penetration hole diameter is less than lower part penetration hole diameter; 4 one-tenth described of the second connectors are cylindrical, and end face upwards extends two side 12, and circular hole is all set on two side, and the second connector 4 upwards arranges screw 5 by bottom; Described intermediate connector 11 is four prism type, and intermediate connector 11 is offered penetration hole on corresponding side between two; Described screw 1 is made up of nut 10 and screw rod; Described screw 1 is through the penetration hole 8 of the first connector 2, and nut is stuck in the first connector 2 bottom penetration holes, and the first connector 2 uses head rod 3 and the second connecting rod 6 to be connected with the second connector 4 by intermediate connector 11.
It is polygon-shaped that described screw nut 10 can be arranged to sectional shape, and the shape and size of nut 10 shape and size and the first connector 2 bottom penetration holes match.
Described head rod 3 passed the circular hole on circular hole, intermediate connector 11 top penetration holes and another sidewall of the first connector on the first connector sidewall 9 successively, blocked by clip 7.
The second described connecting rod 6 passed the circular hole on circular hole, intermediate connector 11 bottom penetration holes and another sidewall of the second connector on the second connector sidewall 12 successively, blocked by clip 7.
Screw 5 diameters and screw 1 screw diameter of the second connector 4 bottoms are coupled.
When use, screw nut may be stuck between the first connector and the second connector, and the screw of the second connector bottom can be connected with another screw, thereby two screws can be linked together.
