The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, the utility model comprises a heavy wall tubing 1, the outer locking fluid cylinder that circumferentially is arranged with of heavy wall tubing 1, and the locking fluid cylinder comprises fluid cylinder lid 3 and the cylinder sleeve 4 that links into an integrated entity by bolt 2.The other end of fluid cylinder lid 3 is located at lower cover 6 on the heavy wall tubing 1 by bolt 5 adapter sleeves, lower cover 6 is located at upper cover plate 8 on the heavy wall tubing 1 by bolt 7 adapter sleeves, be provided with snap ring 9 between upper cover plate 8 and the heavy wall tubing 1, it is circumferentially realized by snap ring 9 and 1 circumferential imperfect circle of heavy wall tubing the location.Between locking fluid cylinder and heavy wall tubing 1, be equipped with a sliding sleeve 10, be arranged with a piston 11 between sliding sleeve 10 and the cylinder sleeve 4, be installed with piston annular space 12 between piston 11 and the sliding sleeve 10.Be provided with back-moving spring 13 between piston 11 and the cylinder sleeve 4.Fluid cylinder lid 3 is provided with an oil-in 14 that is communicated with in the cylinder sleeve 4, and cylinder sleeve 4 is provided with one and is communicated with outside oil-out 15.Heavy wall tubing 1 is arranged at intervals with some locating slots 16 with the contact position of sliding sleeve 10, is used for placement positioning steel ball 17 in the locating slot 16.Sliding sleeve 10 is provided with a keyway mouth 18, correspondence is provided with a feather key 19 in keyway mouth 18, and moving axially of 19 pairs of sliding sleeves 10 of feather key has guide effect, can prevent that sliding sleeve 10 from circumferentially rotating, so that locking ball 17 is pressed in the locating slot 16 locking sliding sleeve 10.
