The place of connecing is lined with O.
On the basis of technique scheme, described adnexa is installed axle and is passed through spiral shell with workbench piston shaft
Stricture of vagina connects and reaches concentric, and polyurethane packing ring is arranged on shoulder bolt and passes through with adnexa installation axle
It is threaded togather.
On the basis of technique scheme, described gas-tpe fitting connects with equipment inner chamber cylinder body, gas
Pipe joint is provided with the structure of engaging button, and extraneous trachea is by the de-company of tearing open of snap-in structure and gas-tpe fitting
Connect.
The beneficial effect that this utility model produces has: 1, plugging structure and the attachment structure of piston
Select floating type flexibly connecting, it is to avoid rigid connection easily causes Remedy for Piston Damage or scratch and produces
The drawback of product；2, plugging structure uses floating structure, in use can school automatically
Positive installation deviation, can make up the impact that deviations brings；3, combination plugging structure seals
Mode is consistent with air inlet pipe mounting means essentially with air inlet pipe entrucking mode, makes closure
Detect and apply closer to reality；And its plugging effect is more stable reliably makes Detection results more steady
Fixed.4, plugging structure can be by adjusting the part 4 size with part 5 to adapt to certain model
Enclosing the product caliber of interior different size, its structure tends to standardization, conveniently calls replacing, reduces
The workload of design, is also more conducive to change installation in production engineering.
