circle can reach pulled-up condition, and the tapering of male joint and female joint connecting thread is 1:3; Or rotate when connecting
circle can reach pulled-up condition, and the tapering of male joint and female joint connecting thread is 1:8.
Described stake is entered formula and is connected, and male joint is identical with outer tube diameter with female joint external diameter, and internal diameter is less than body, rotates during connection
circle can reach pulled-up condition, and the tapering of male joint and female joint connecting thread is 1:3; Or rotate when connecting
circle can reach pulled-up condition, and the tapering of male joint and female joint connecting thread is 1:8.
Described male joint there is shoulder to design.
Described female joint end face and male joint circular bead surface contact position adopt end face seal, the mechanical seal that female joint threaded upper portion medial surface and male joint lateral surface adopt.
Described anti-downly turn locking device, can be the locking slot being installed to male joint by External Force Acting, also can be coordinate by tooth the locking slot being installed to male joint.
Compared with prior art, advantage of the present invention is:
1, four head thread waterproof casing Quick Connect Kits, on-the-spot spreading connects the efficiency that improve about 4 times, installs faster, reduces the activity duration;
2, form of structure has 4 kinds, can need to carry out choose reasonable according to production etc., is more practically applicable to drilling well and produces;
3, three seal structures, can ensure fastness when installing, its good sealing effect, firmly safer;
4, two kinds of locking modes, require unrestricted choice according to user, can lock pin and box sub further after screw thread tightens, and prevent the phenomenon of screw thread back-off in work progress, and guarantee safe production construction.
5, four head thread waterproof casing Quick Connect Kits use faster, and connection speed is 4 times that original one start screw connects, and substantially increase the speed that sleeve pipe connects, improve the efficiency of drilling well.

Detailed description of the invention
Embodiments of the invention are described in detail below in conjunction with accompanying drawing.
Take specification as Φ 610mm × 25.4mm type be example.Four head thread waterproof casing Quick Connect Kits, are connected by male joint female joint, and sealing means is the sealing of O RunddichtringO, and female joint adopts with male joint and is threaded, and locking device is locked, and female joint and male joint relatively rotate
or
circle can reach pulled-up condition, is designed with anti-downly to turn locking device between male joint and female joint; Connection can be drilling type connection or formula connection is entered in stake.
Described drilling type connects, and male joint and female joint external diameter are greater than outer tube diameter, rotate during connection
circle can reach pulled-up condition, and the tapering of male joint and female joint connecting thread is 1:3, and pitch is 10mm relatively greatly, and screw thread tooth depth is 5.3mm; Or rotate when connecting
circle can reach pulled-up condition, and the tapering of male joint and female joint connecting thread is 1:8, and pitch is relatively little is 8.5mm, and screw thread tooth depth is 4.9mm.
