Embodiment
Below in conjunction with the accompanying drawing 1-2 in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out it is clear,
Complete description, it is clear that described embodiment is only the part of the embodiment in the present invention, rather than whole implementation
Example.Based on the present embodiment, other embodiment that those skilled in the art are obtained on the premise of creative work is not made,
It is within the scope of the present invention.
It is a kind of structural representation of link rod connection component provided by the invention as shown in Figure 1, including needs what is connected
First insulating bar 1, the second insulating bar 2, grafting tongue are first 3, grafting groove first 4 and outer buckle annulus 5.
Grafting tongue is first 3, grafting groove first 4 is all to be fixedly connected on the first insulating bar 1 and the second insulating bar by screw 6
On 2 one end（The work head and lever being connected respectively with the first insulating bar 1, the other end of the second insulating bar 2 are not shown）,
The quantity of screw 6 per junction can be 2,3 or 4, be evenly distributed on the ring part of junction.Grafting tongue is first 3,
Grafting groove first 4 and the first insulating bar 1, the connection of the second insulating bar 2 can also use the other modes that industry is commonly used, such as local
Heat fixed form.
Fig. 2 is the decomposition texture schematic diagram of link rod connection component, can more clearly understand their structure.Grafting is recessed
The front end of trough 4 is provided with the axis of guide 43, and the axis of guide 43 is processed as cylindrical structural, uniform in the center section of grafting groove first 4
4 grooves 41 are provided with, wherein being provided with horizontal card slot 42 again in the bottom of 2 symmetrical grooves 41.Grafting tongue first 3 is processed
Into cylindrical shape, it is easy to first 4 insertion of grafting groove inside it, in order to prevent from rotating after grafting that its outermost end is provided with 4
Tongue 31（2 are only shown in Fig. 2）, tongue 31 is integrally formed with cylinder body.There are 2 inside the edge of outer buckle annulus 5
Projection 51, outer buckle annulus 5, which is set, surrounds grafting tongue first 3, and can be moved on grafting tongue head.
Grafting tongue is first 3, grafting groove is first 4, outer buckle annulus 5 is that metal material is made, the axis of three and the
One insulating bar 1, the axis of the second insulating bar 2 overlap.
In connection, the axis of guide 43 of grafting groove first 4 is inserted inside grafting tongue first 3, tongue 31 blocks groove 41,
Formed to turn to and fixed, therefore tongue 31 needs to be set as what is matched with the shape of groove 41, the diameter of the axis of guide 43 is less than cylindrical shape
The internal diameter of structure；Then outer buckle annulus 5 is promoted, one part is moved to from grafting tongue first 3 on grafting groove first 4,
Rotate and 2 projections 51 at its edge is blocked horizontal card slot 42, form axial restraint.
Projection 51 and horizontal card slot 42 may be alternatively provided as 4, as long as guarantee is uniform, is fully connected.
The link rod connection component can need to connect more piece insulating bar, structure and connected mode and this reality according to physical length
It is identical to apply example.Further, Anti-slip cover can be installed additional on every section insulating bar, can specifically uses rubber antiskid set, be advantageous to improve
The grasping dynamics of operating personnel, prevent from sliding in link rod attended operation.
In attended operation, grafting groove head, grafting tongue head are first respectively fixedly connected with the two section insulation in link rod
On bar；Then grafting groove head being inserted inside grafting tongue head, the tongue of grafting tongue head blocks the groove of grafting groove head,
Prevent link rod axial rotation；Finally outer buckle annulus is moved on grafting groove head, and rotates fixation, prevents crane mandrel
To pulling.Link rod connection component in the present invention instead of traditional screw connection structure, effectively overcome in the prior art
Insulating bar existing deformed threads, damage, dirty or the problems such as block in connection, while the connection component can prevent from making
Gram mandrel improves the stability of connection to rotationally and axially pulling, and the connection component is simple to operate, time saving and energy saving.
It should be appreciated that the invention is not limited in the precision architecture for being described above and being shown in the drawings, can
To carry out various modifications and improvements on the basis of without departing from the scope.Follow the general principle of the present invention or including this technology
The modified scheme of common knowledge, customary means in field, in the application protection domain.
