Specific embodiment
As shown in Figures 1 to 6, a kind of miniature high-speed piston type electric vacuum pump piston stablizes connecting rod, it is in order to effective
Increase the stability in the service life and moving process of piston structure in use and design, apply it to miniature high-speed
In piston type electric vacuum pump, can miniature high-speed piston type electric vacuum pump can preferably play a role, using it
When stability it is more reliable, vacuumizing effect is also more preferable.It is living in miniature high-speed piston type electric vacuum pump in vacuum
By setting shifting sledge on the piston rod when filling in capable movement, piston structure is made more to stablize in moving process, Neng Gouyou
Effect increases the service life of piston structure, so as to increase the service life of miniature high-speed piston type electric vacuum pump.It includes circle
Cylindrical bodies connecting pole 1, it is the agent structure of piston rod.The lower end of the main body connecting pole 1 is equipped with the identical cylinder of diameter
Shape is linked and packed first 2, be linked and packed first 2 be wrapped in when in use by piston ring in.First 2 and the main body of being linked and packed
It is linked together between connecting pole 1 by cylindrical seal connecting pole 3, enables piston ring that will be linked and packed and first 2 wrap up more
Tightly, make piston structure and the indoor connection sealing of plunger shaft more preferable.The diameter for being tightly connected column 3 is less than the main body
The diameter of connecting pole 1, the better tightness that piston ring can in this way assembled.The upper and lower ends for being tightly connected column 3 point
It does not set there are one the close connection conical surface 4, on the one hand can facilitate processing, the cost for making production is lower, on the other hand makes it with living
The connection of plug ring is closer, and smaller is worn in moving process, and the service life for making piston ring is longer.Two close connections
The tapered direction of the conical surface 4 is opposite, the diameter of the diameter and the main body connecting pole 1 of the larger diameter end of the close connection conical surface 4
