Abstract
The utility model provides a connecting rod applied to an air compressor, which belongs to the technical field of machinery, and solves the problem of insecure positioning of the connecting rod and a piston pin in the prior art. The connecting rod applied to the air compressor comprises a rod body of which the section is of an 'H' shape; a small connecting rod head is arranged at one end of the rod body; an axle hole 1 connected with the piston pin is arranged at the middle part of the small connecting head; a large connecting rod head is arranged at the other end of the rod body; an axle hole 2 connected with a bent axle is formed in the middle part of the large connecting rod head; a connecting rod lid is arranged outside the large connecting rod head; three positioning holes which are evenly distributed in the radial end face are formed in the small connecting rod head and respectively communicated with the inner wall and the outer wall of the small connecting rod head. The connecting rod applied to the air compressor has the advantage of being reliable to position.
Description
Technical field
The utility model belongs to field of mechanical technique, has related to a kind of connecting rod, has especially related to a kind of for the connecting rod on the air compressor.
Background technique
In air compressor, the effect of connecting rod is that the power that piston bears is passed to bent axle, and makes the to-and-fro motion of piston change rotatablely moving of bent axle into.Connecting rod is made up of parts such as connecting rod shank, connecting rod small end, connnecting rod big ends, and connecting rod small end is used for installing wrist pin, to connect piston.Shaft is made " worker " or " H " shape section usually, in the hope of reduce quality under the prerequisite that satisfies the strength and stiffness requirement.Connnecting rod big end links to each other with the rod journal of bent axle, and there is the illusive shortcoming in location in the existing connecting rod that is applied on the air compressor.
Summary of the invention
The utility model is at the problems referred to above that prior art exists, and proposed a kind ofly for the connecting rod on the air compressor, has the firm advantage in location between this connecting rod and the wrist pin.
The utility model is realized by following technical proposal: a kind of for the connecting rod on the air compressor, comprise that section is the body of rod of " H " shape, one end of the described body of rod is connecting rod small end, the middle part of described connecting rod small end has the axis hole one that is connected with wrist pin, the other end of the described body of rod is connnecting rod big end, the middle part of described connnecting rod big end has the axis hole two that is connected with bent axle, the outside of described connnecting rod big end is connecting rod cap, it is characterized in that, have three positioning holes that are distributed on its radial end face on the described connecting rod small end, described positioning hole is connected with the inner and outer wall of described connecting rod small end respectively.
Above-mentioned a kind of for the connecting rod on the air compressor, a side of described connecting rod cap has bolt hole.
Above-mentioned a kind of for the connecting rod on the air compressor, described body of rod middle part has poly-oilhole.
Compared with prior art, this connecting rod that is used on the air compressor has positioning hole at connecting rod small end, and bolt passes positioning hole and wrist pin is fixed, and has the firm advantage in location.
Description of drawings
Fig. 1 is this structural representation that is used for the connecting rod on the air compressor.
Among the figure, 1, the body of rod; 2, connecting rod small end; 3, connnecting rod big end; 4, axis hole one; 5, axis hole two; 6, bolt hole; 7, poly-oilhole; 8, connecting rod cap; 9, positioning hole.
Embodiment
Below be specific embodiment of the utility model, and by reference to the accompanying drawings the technical solution of the utility model be further described, but the utility model is not limited to these embodiments.
As shown in Figure 1 a kind of for the connecting rod on the air compressor comprises that section is the body of rod 1 of " H " shape, and the described body of rod 1 middle part has poly-oilhole 7; One end of the described body of rod 1 is connecting rod small end 2, and the middle part of described connecting rod small end 2 has the axis hole 1 that is connected with wrist pin; The other end of the described body of rod 1 is connnecting rod big end 3, and the middle part of described connnecting rod big end 3 has the axis hole 25 that is connected with bent axle, and the outside of described connnecting rod big end 3 is connecting rod cap 8, and a side of described connecting rod cap 8 has bolt hole 6; Have three positioning holes 9 that are distributed on its radial end face on the described connecting rod small end 2, described positioning hole 9 is connected with the inner and outer wall of described connecting rod small end 2 respectively.
Specific embodiment described herein only is that the utility model spirit is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
