Background technology
Connecting rod in air compressor machine is for connecting piston and bent axle, and in air compressor machine, connecting rod is used for the rotary motion of bent axle
It is converted into moving along a straight line, cylinder body is equipped in the top side of cylinder block, and piston, one end of piston and company are equipped in cylinder interior
The front end connection of bar.The rotary motion of bent axle is converted into the straight line fortune of piston by the swing of connecting rod when accessing external power supply
It is dynamic so that piston moves back and forth in cylinder interior.Connecting rod in existing air compressor machine with bent axle to be fixedly connected, piston and company
Bar is then flexible connection, and concrete structure is connected between piston and connecting rod by piston pin, and piston pin passes through connecting rod, piston pin
Needle bearing is provided between connecting rod.
In the air compressor machine course of work, connecting rod is periodically continual swing, after prolonged work, piston pin and rolling
Needle bearing is easily worn, and link assembly damage causes complete machine that cannot use, service life substantially reduces.
Invention content
The purpose of the present invention is being directed to the above-mentioned problems in the prior art, it is small to provide a kind of frictional resistance, uses
The air compressor machine compression mechanism of long lifespan.
The purpose of the present invention can be realized by following technical proposal：A kind of air compressor machine compression mechanism, the air compressor machine is by song
Axle box, piston, connecting rod, valve plate, fan blade and two cylinder body compositions, cylinder body are installed on the both sides up and down of crankcase, have in crankcase
There is the bent axle of eccentric setting, which is characterized in that the connecting rod is symmetrical above and below, and the upper and lower end of the connecting rod is pacified
Equipped with the mandril being fixedly connected for piston, the slideway for stretching into for bent axle and laterally sliding is offered in the middle part of the connecting rod, it is described
Bent axle and slideway between be provided with bearing, the both sides of the connecting rod are installed with respectively can limit bearing axial float
Pressing plate, to be slidably matched between the bearing and slideway inner wall.
In a kind of above-mentioned air compressor machine compression mechanism, the vertical section of the slideway by about two parallel straight lines and
Two symmetrical semi arches surround, and the radius of semi arch is identical with the outer diameter of bearing.
In a kind of above-mentioned air compressor machine compression mechanism, identical with slideway shape lead to is offered in the middle part of the pressing plate
Hole slot.
In a kind of above-mentioned air compressor machine compression mechanism, the upper lower wall of the through-hole groove is smaller than lower wall on slideway
Spacing.
In a kind of above-mentioned air compressor machine compression mechanism, the bearing is needle bearing.
Compared with prior art, the link design in this air compressor machine compression mechanism is into both ends symmetrical structure, upper and lower ends
It is fixedly connected with the piston, middle part opens up the slideway laterally slided for bent axle, and needle bearing is set between bent axle and slideway.Work as sky
Band dynamic crankshaft rotates during compressor operation, and the bent axle of rotation, which touches, makes connecting rod do linear motion up and down, is connected in connecting rod upper and lower ends
Piston moves reciprocatingly in cylinder body, so as to fulfill compressed air.This structure design changes traditional air compressor machine link mechanism
Operation principle avoids the friction damage of link assembly caused by connecting rod is continuously swung, and extend air compressor machine component uses the longevity
Life.

Specific embodiment
The following is specific embodiments of the present invention and with reference to attached drawing, technical scheme of the present invention is further described,
But the present invention is not limited to these embodiments.
As shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5, by bent axle 6 casees 1, piston, connecting rod 2, valve plate 3, fan blade 4 in this air compressor machine
It being formed with two cylinder bodies 5, cylinder body 5 is installed on the both sides up and down of bent axle 6 casees 1, has the bent axles 6 of eccentric setting in bent axle 6 casees 1,
For connecting rod 2 to be symmetrical above and below, the upper and lower end of connecting rod 2 is mounted on the mandril 7 being fixedly connected for piston, in connecting rod 2
Portion offers the slideway 8 for stretching into for bent axle 6 and laterally sliding, and bearing 9, the both sides of connecting rod 2 are provided between bent axle 6 and slideway 8
