Description
Technical field
The utility model discloses a kind of vacuum pump, belong to the vacuum pump technology field.
Background technique
At present, the small pump on the market mainly is to utilize centrifugal action that liquid is sucked and discharges, and the drive mechanism in it is complicated, and hydraulic system, transmission system etc. are arranged, and structure member is many, and assembling is complicated, and volume is big, and cost is high.
The model utility content
The technical problem that the utility model will solve has provided a kind of simple in structure, and volume is little, make easy to assembly, the vacuum pump that cost is low.
For solving the problems of the technologies described above, the utility model is realized through following technological scheme:
A kind of vacuum pump comprises the feed liquor system and the discharge opeing system that drive cylinder body, vacuum cylinder body, live axle, drive link and one-way valve is set, and driving cylinder body, vacuum cylinder body are fixed on the support; Live axle one end is in driving cylinder body, and its periphery has elliptical slot, and it is external that the other end stretches out drive cylinder; Driving in the cylinder body has one by driving casing, and an end and drive link are fixed, and live axle rotates in by driving casing; By driving casing internal fixation one bearing, the width of the elliptical slot on the diameter of this bearing and the live axle periphery matches, and this bearing can rotate along elliptical slot; By driving casing relative parallel slot is arranged outward, its width matches with being fixed on the diameter that drives bearing relative on the inboard wall of cylinder block, and the other end of drive link is in the vacuum cylinder body; Nut, seal ring are arranged on its termination, and seal ring seals up the vacuum cylinder body.
Adopt the vacuum pump of this structure, when rotating driveshaft, rotated along the elliptical slot on the live axle by the bearing of driving casing internal fixation; Because oval-shaped groove can impel by driving casing to move reciprocatingly, simultaneously; Be fixed on and drive that relative bearing also moves reciprocatingly on the inboard wall of cylinder block in relative parallel slot is arranged outside the driving casing, squint in the time of can preventing move, done repeating motion by driving casing drive drive link by driving casing; The drive link seal ring seals up the vacuum cylinder body, and the feed liquor system and the discharge opeing system of one-way valve is set on the vacuum cylinder body, thereby can smoothly liquid sucked and discharge; This vacuum pump structure is simple; Volume is little, makes easy to assemblyly, and cost is low.The rotation of live axle, available artificial the drive, also useable electric moter drives.Need not pour water, just can directly absorb water.
Description of drawings
Fig. 1 is the utility model sectional structure schematic representation.
Specific embodiment
With reference to Fig. 1, driving cylinder body 2, vacuum cylinder body 3 are fixed on the support 1, when rotating driveshaft 4; Oval-shaped groove rotated along the elliptical slot 14 on the live axle 4 by the bearing 6 of driving casing 8 internal fixation, because can impel by driving casing 8 to move reciprocatingly; Simultaneously, be fixed on and drive bearing 7 relative on cylinder body 2 inwalls, squint when having prevented by driving casing 8 motions along also being moved reciprocatingly in the equality groove 5 relative outside the driving casing 8; Driven drive link 9 by driving casing 8 and do repeating motion, the seal ring 10 on the drive link 9 seals up vacuum cylinder body 3, and the feed liquor system 13 and discharge opeing system 11 of one-way valve is set on the vacuum cylinder body 3; Nut 12 is fixed on seal ring 10 on the drive link 9, thereby can smoothly liquid sucked and discharge, and this vacuum pump structure is simple; Volume is little, makes easy to assemblyly, and cost is low.The rotation of live axle, available artificial the drive, also useable electric moter drives, and need not pour water, and just can directly absorb water
Claims (1)
