Abstract
The invention provides a connecting rod. The connecting rod comprises a connecting rod small end, a rod body and a connecting rod big end, wherein a plurality of columnar friction members are arranged at the inner walls of the connecting rod small end and the connecting rod big end and are connected with the inner walls of the connecting rod small end and the connecting rod big end through locking bolts; the connecting rod body comprises a first rod body and a second rod body, the second rod body is connected in the first rod body and can movably stretch and shrink, and a spring is arranged in the second rod body; three columnar friction members are arranged at the inner wall of the connecting rod small end, and three columnar friction members are arranged on the inner wall of the connecting rod big end; a guiding trough is formed in one side of the first rod body, and the second rod body is connected to the guiding trough through a sliding block. According to the connecting rod, not only can the sizes of the connecting rod small end and the connecting rod big end be regulated, but also the length change of the connecting rod body can be met.
Description
Technical field
The present invention relates to a kind of driving component, relate in particular to a kind of connecting rod.
Background technique
Connecting rod is that in linkage mechanism, two ends are hinged to transmit the rod member of motion and power with active and driven member respectively, the power that piston is born is passed to bent axle, and the to-and-fro motion that makes piston changes rotatablely moving of bent axle into, existing connecting rod is the composition of connecting rod small end, shaft and connnecting rod big end, cannot adjust the size of connecting rod small end, connnecting rod big end, and cannot meet the variation of connecting rod shank length length.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of connecting rod is provided, not only can adjust the size of connecting rod small end, connnecting rod big end, and can meet the variation of connecting rod shank length.
In order to solve the problems of the technologies described above, technological scheme provided by the invention is:
A kind of connecting rod, comprises connecting rod small end, shaft and connnecting rod big end, and described connecting rod small end inwall and connnecting rod big end inwall are equipped with multiple cylindricality friction members, and described cylindricality friction member is connected with connecting rod small end inwall, connnecting rod big end inwall by lock bolt; Described connecting rod shank comprises the first shaft and the second shaft, and described the second shaft is connected to the first shaft inside, and movable telescopic is provided with spring in described the second shaft;
Described connecting rod small end inwall is provided with three cylindricality friction members, and connnecting rod big end inwall is provided with three cylindricality friction members;
Described the first shaft one side is provided with guiding groove, and described the second shaft is connected on guiding groove by slide block;
The diameter of described the second shaft is less than the diameter of the first shaft.
By above technological scheme, with respect to prior art, the present invention has following beneficial effect:
The present invention, by adjusting the position of lock bolt, makes the position adjustment of cylindricality friction member, thereby can adjust the size of connnecting rod big end, connnecting rod big end, better easy-to-operat; Connecting rod shank comprises the first shaft and the second shaft, and described the second shaft is connected to the first shaft inside, movable telescopic, the variation of length length while meeting connecting rod operation; In the second shaft, be provided with spring, when reducing connecting rod weight, do not affect the performance of connecting rod.
Accompanying drawing explanation
