Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment:
Like Fig. 1, the dry powder bottle cylindrical shell free body hydraulic pressure test chuck shown in 2, have anchor clamps, square and oil cylinder discharge water; The chuck pull bar 1 that through hole is arranged in the middle of said anchor clamps comprise; There is a lock sleeve 3 chuck pull bar outside; Lock sleeve 3 outsides are with locking orienting sleeve 4, are connected with three staies 2 above the lock sleeve, and said oil cylinder comprises cylinder body 10; Piston 7 and the middle oil cylinder axle 11 that is provided with through hole are installed in cylinder body, O-ring seal are housed below and dust ring 8 seals.The said square 9 that discharges water is provided with paddle hole 14, and the inside is provided with two-layer O-ring seal 6; Discharge water headkerchief 5 is housed above the square 9, be provided with connecting hole in the middle of the said headkerchief, said locking orienting sleeve 4 with being threaded in above the headkerchief, and adopts O shape circle 13 that locking orienting sleeve and headkerchief are sealed through connecting hole.
