Abstract
The invention discloses a connecting rod. The connecting rod comprises a large end, a rod body and a small end which are sequentially and fixedly connected, the section of the large end is larger than that of the small end, a semicircular section structure is arranged on the large end, a round through hole is formed at the center of the large end, a trapezoidal section structure is arranged at the small end, and a chamfered fillet is arranged at a position where the small end is connected with the rod body. Through the mode, the connecting rod breaks through a structure that round holes are necessarily formed on two ends of the traditional connecting rod, and is simple in structure, and low in installation error sensitivity.
Description
Technical field
The present invention relates to driving mechanism, particularly relate to a kind of connecting rod.
Background technique
Connecting rod mechanism movement is various informative, can realize the compound movements such as rotation, swing and movement in plane or the space, therefore, linkage mechanism is widely used in various machineries, instrument and the electronic product, it is less that its advantage mainly contains the connecting rod pressure, the face contact is convenient to lubricate, and it is less, easily manufactured to wear and tear.Connecting rod be in the linkage mechanism two ends respectively with the hinged thick stick spare that transmits motion and power of dirivig member and driven member, because traditional connecting rod mostly is steel plate, the cross section of its main body mostly is circle or I shape, there is circular hole at two ends, be equiped with lining or bearing in the circular hole, consist of hinged for packing pivot pin into, when given motion requires when more or complicated, the number of components and the connecting rod that need are also more, like this so that the linkage mechanism complex structure, working efficiency reduces, to the susceptibility increase of alignment error.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of simple in structure, the connecting rod little to the alignment error susceptibility.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of connecting rod is provided, comprises: the large end, shaft and the small end that are fixedly connected sequentially; Described large end section is greater than described little end section; Described large end is provided with the semi-circular cross-section structure, and described large end center is provided with manhole; Described small end is provided with the trapezoid cross section structure, and described small end and described shaft joint are provided with rounding.
In a preferred embodiment of the present invention, described small end and shaft joint width are less than the width of the other end of small end.
The invention has the beneficial effects as follows: bar linkage structure of the present invention is simple, lower to the susceptibility of alignment error, using effect good.
Description of drawings
Fig. 1 is the plan view of connecting rod one preferred embodiment of the present invention;
The mark of each parts is as follows in the accompanying drawing: 1, large end, 11, semi-circular cross-section, 12, manhole, 2, shaft, 3, small end.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
See also Fig. 1, a kind of connecting rod, comprise the large end 1, shaft 2 and the small end 3 that are fixedly connected sequentially, large end 1 cross section is greater than small end 3 cross sections, large end 1 is provided with semi-circular cross-section 11 structures, and hold greatly 1 center to be provided with manhole 12, small end 3 is provided with the trapezoid cross section structure, and small end 3 is provided with rounding with shaft 2 joints.In addition, small end 3 and the width of shaft 2 joint width less than small end 3 other ends.
Connecting rod of the present invention, shaft 2 one ends are provided with large end 1, an other end is provided with small end 3, large end 1 is provided with manhole 12, small end 3 is provided with the trapezoid cross section structure, during assembling, large end 1 lining or the bearing by being equiped with in the manhole 12, consist of hinged with the pivot pin that matches, small end 3 directly is installed in the groove of offering on the spherical, because small end 3 and the width of shaft 2 joint width less than small end 3 other ends, so that small end 3 is when moving with spherical, can the separable spherical face, therefore, the susceptibility of 3 pairs of alignment errors of small end has been broken traditional connecting rod two ends all must be provided with circular hole than end 1 is low greatly, during assembling, must could consist of hinged working state by two circular holes.
Be different from prior art, bar linkage structure of the present invention is simple, lower to the susceptibility of alignment error, broken traditional connecting rod two ends and all must establish round-meshed idea.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
Claims (2)
1. a connecting rod is characterized in that, comprising: the large end, shaft and the small end that are fixedly connected sequentially; Described large end section is greater than described little end section; Described large end is provided with the semi-circular cross-section structure, and described large end center is provided with manhole; Described small end is provided with the trapezoid cross section structure, and described small end and described shaft joint are provided with rounding.
2. connecting rod according to claim 1 is characterized in that, described small end and described shaft joint width are less than the width of the other end of described small end.
