Abstract
The utility model discloses a high strength locking type sleeve tie-in, which includes a connecting sleeve which can hitch the two meeting pipes. The two ends of the connecting sleeve is screwed with a locking sleeve outside, the pipe opening on the screwed end of the locking sleeve and the connecting sleeve is provided with an inner screw thread for screwing, and the pipe opening on the other end of the locking sleeve is sleeved on the meeting pipe. The pipe diameter of the screwing end of the locking sleeve and the connecting sleeve is bigger than the pipe diameter of the pipe opening of the other end section, and the middle transitional section is a sealing and locking inclined section, and an obturating ring and a locking ring are arranged in the meeting pipe of the inclined section and the inner sleeve. The locking ring consists of a bottom annular platform and a group of lugs inclining upwards from the outer ring; the bottom annular platform of the locking ring and the obturating ring match each other close. The utility model has the higher connecting intensity and the close leak tightness, and is applicable for the quick connection and high degree sealing of the metal pipelines in the construction industry.
Description
Technical field
The utility model relates to the sleeve joint of a kind of high strength locking.
Background technique
In building, outside the electric wire that connects of job site or equipment room, optical cable, all be with the protection thin-wall steel tube; hurt, damaged preventing; the normal in the past Placement that adopts screw thread, withholds, presses closer of the connection between thin-wall steel tube; and the employing of these modes more or less all have a major defect; especially can not guarantee rigorous sealing; regular meeting has gas, liquid or impurity particle to infiltrate or spills in construction is used; electric wire, optical cable are caused corrode injury, make troubles and potential safety hazard to installation.
Summary of the invention
The purpose of this utility model provide a kind of collect connect with sealing function be the high strength locking sleeve joint of one.
For achieving the above object, the utility model is taked following design proposal:
The sleeve joint of a kind of high strength locking comprises that one is used to entangle the connecting sleeve of two butt tubes, is bolted with lock sleeve outside the two ends of described connecting sleeve; The end mouth of pipe that described lock sleeve and connecting sleeve are spirally connected is offered to be spirally connected and is used internal thread, and the mouth of pipe section of the other end closely is linked on the butt tube; Lock sleeve and connecting sleeve are spirally connected the caliber of end greater than the caliber of the other end mouth of pipe section, and the middle transition section use bevel phase for sealing, locking, are equipped with sealing between the butt tube of this bevel phase and interior cover and use and enclose and locking ring.
Obliquely lug constitutes described locking ring from the outer ring by the annular platform of bottom and one group.
The utility model has the advantages that: use connection easy, and have higher join strength and tight sealing, can satisfy in the construction industry the quick connection of metallic conduit and the requirement of high-seal.

Embodiment
As shown in Figure 1, the sleeve joint of the utility model high strength locking comprises that one is used to entangle the connecting sleeve 5 of two butt tubes 1, is bolted with lock sleeve 2 outside the two ends of connecting sleeve.The end mouth of pipe that described lock sleeve 2 and connecting sleeve are spirally connected is offered to be spirally connected and is used internal thread, the mouth of pipe section of the other end closely is linked on the butt tube 1, lock sleeve and connecting sleeve are spirally connected the caliber of end greater than the caliber of the other end mouth of pipe section, the middle transition section is used bevel phase, 1 of the butt tube of this bevel phase and interior cover for sealing, locking and is equipped with sealing circle 4 and locking ring 3.
Referring to Fig. 1, Fig. 2, connecting sleeve 5 entangles two butt tubes 1, the port 502 interior inclined-planes that two and lock sleeve are spirally connected and hold; Connecting sleeve can dock 501 place's indents at middle two butt tubes.
Referring to Fig. 3, described lock sleeve 2 closely is linked in and has cover rotation special hole 201 on the mouth of pipe section of docking pipe end; Middle transition bevel phase bevel angle is not limit, and is good with 70 ± 5 °.
Referring to Fig. 4-A, Fig. 4-B, obliquely lug 302 constitutes described locking ring 3 from the outer ring by the annular platform 301 of bottom and one group.This group lug can be a plurality of, and is good equidistantly to be set to, and lug is four equidistant protruding semicircle sheets that are provided with in the present embodiment, is beneficial to tighten.The lug gradient α of locking ring does not limit, and is good with 5～35 °.
Described sealing is O shape circles of being made by rubber with circle 4, and its longitudinal plane be a circle or square (referring to Fig. 5-A, Fig. 5-B).
During assembling, described locking ring bottom annular platform closely cooperates with circle with sealing.
The utility model high strength locking sleeve joint locking principle: when overlapping 2 with the special tool rotational lock, seal ring 4 is under the effect on sleeve pipe 5 end inclined-planes 502, compress to locking ring 3 bottom surfaces, make lug (four semicircle lugs in the present embodiment) in the locking ring, enter lock sleeve matching hole section under the lock sleeve ramp effect and by sleeve pipe between, and compress by sleeve pipe, simultaneously since the locking ring bottom to the active force of seal ring and the centripetal force of cannula bevel 502, make seal ring 4 and compressed mutually by sleeve pipe 1 and cannula bevel 502.Connecting sleeve is formed simultaneously have the effect that high strength connects and seals.
The utility model is broken through the no sealing of product in the past, and will seal and locking combines together, the alternative method that is welded to connect in the past, and, make it have high electrical continuity because the high strength that this product possessed connects the locking property.
