Description of the drawings
In order to illustrate more clearly of the technical scheme in the embodiment of the utility model, will make below to required in embodiment
Attached drawing is briefly introduced.
Fig. 1 is the structure diagram of the link rod connection component shown in the present embodiment；
Fig. 2 be the present embodiment in order can stick connection component decomposition texture schematic diagram；
Wherein, the first insulating bars of 1-, the second insulating bars of 2-, 3- grafting tongue heads, 31- tongues, 4- grafting groove heads, 41-
Groove, 42- horizontal card slots, 43- guiding axis, be buckled outside 5- annulus, 51- protrusions, 6- screws.
Specific embodiment
Below in conjunction with the attached drawing 1-2 in utility model embodiment, to the technical scheme in the embodiment of the utility model into
Clear, the complete description of row, it is clear that described embodiment be only part of the embodiment in the utility model rather than
Whole embodiments.Based on the present embodiment, what those skilled in the art were obtained on the premise of creative work is not made
Other embodiment, in the protection domain of the application.
It is as shown in Figure 1 a kind of structure diagram of link rod connection component provided by the utility model, including needing to connect
The first insulating bar 1, the second insulating bar 2, the grafting tongue that connect 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 1,2 other end of the second insulating bar 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 common other modes of industry, 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
4 front end of trough is provided with guiding axis 43, and guiding axis 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 inserted into convenient for grafting groove first 4 inside it, is rotated in order to prevent after grafting and its outermost end is provided with 4
Tongue 31（2 are only shown in Fig. 2）, tongue 31 and cylinder body are integrally formed.There are 2 inside the edge of outer buckle annulus 5
Protrusion 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 central axes of three and the
