Abstract
The invention discloses a kind of connecting rod, including：Big end, shaft and the small end being fixedly connected sequentially, the big end section is more than the small end section, and the big end is provided with semi-circular cross-section structure, and is provided with manhole at the big end center, the small end is provided with trapezoid cross section structure, and the small end is provided with rounding with the shaft junction.By the above-mentioned means, a kind of connecting rod of the present invention has broken the structure, simple in construction, relatively low to the susceptibility of alignment error that traditional connecting rod two end all must be provided with circular hole.
Description
Technical field
The present invention relates to transmission mechanism, more particularly to a kind of connecting rod.
Background technology
Connecting rod mechanism movement is various informative, it is possible to achieve the compound movement such as rotation, swing and movement in plane or space,
Therefore, linkage is widely used in various machineries, instrument and electronic product, its advantage mainly have connecting rod pressure compared with
Small, face contact is easy to lubricate, and abrasion is smaller, easily manufactured.Connecting rod be in linkage both ends respectively with driving member and driven
Component is hinged to transmit the thick stick part of motion and power, and because traditional connecting rod is mostly steel plate, the section of its main part is mostly circle
Or it is I-shaped, there is circular hole at both ends, and bushing or bearing are equiped with circular hole, for load pivot pin and form it is be hinged, when given
When movement needs are more or more complicated, it is necessary to number of components and connecting rod it is also more, so that linkage arrangement is complicated, work
Make efficiency reduction, the susceptibility increase to alignment error.
The content of the invention
The present invention solves the technical problem of provide a kind of connecting rod simple in construction, small to alignment error susceptibility.
In order to solve the above technical problems, one aspect of the present invention is：A kind of connecting rod is provided, including：Successively
Big end, shaft and the small end being fixedly connected；The big end section is more than the small end section；The big end is provided with semi-circular cross-section
Structure, and it is provided with manhole at the big end center；The small end is provided with trapezoid cross section structure, and the small end and the bar
Body junction is provided with rounding.
In a preferred embodiment of the present invention, the small end is less than the other end of width of small end with shaft junction width
Degree.
The beneficial effects of the invention are as follows：Bar linkage structure of the present invention is simple, using effect relatively low to the susceptibility of alignment error
It is good.
Brief description of the drawings
Fig. 1 is the front view of the preferred embodiment of connecting rod one of the present invention；The mark of each part is as follows in accompanying drawing：1st, big end, 11,
Semi-circular cross-section, 12, manhole, 2, shaft, 3, small end.
Embodiment
Presently preferred embodiments of the present invention is described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.It please join
Fig. 1, a kind of connecting rod are read, including big end 1, shaft 2 and the small end 3 being fixedly connected sequentially, it is big to hold 1 section to be more than the section of small end 3,
Big end 1 is provided with the structure of semi-circular cross-section 11, and is provided with manhole 12 at 1 center of big end, and small end 3 is provided with trapezoid cross section structure,
And small end 3 is provided with rounding with the junction of shaft 2.In addition, small end 3 is less than the other end of small end 3 with the junction width of shaft 2
Width.
Connecting rod of the present invention, the one end of shaft 2 are provided with big end 1, and other end is provided with small end 3, and big end 1 is provided with circle
Through hole 12, small end 3 are provided with trapezoid cross section structure, big to hold 1 bushing or bearing by being equiped with manhole 12 during assembling,
Form and be hinged with the pivot pin being engaged, small end 3 is directly mounted in the groove opened up on spherical, due to small end 3 and shaft 2
Junction width is less than 3 other end of width of small end so that when small end 3 moves with spherical, without departing from spherical, because
This, small end 3 is lower than big end 1 to the susceptibility of alignment error, has broken traditional connecting rod two end and all must be provided with circular hole, has assembled
When, it is necessary to it could form be hinged working condition by two circular holes.
Be different from prior art, bar linkage structure of the present invention is simple, it is relatively low to the susceptibility of alignment error, broken it is traditional
Connecting rod two end all must be provided with the idea of circular hole.
Embodiments of the invention are the foregoing is only, are not intended to limit the scope of the invention, it is every to utilize this hair
The equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
