Abstract
The utility model discloses a trip preventing air tool pipe junction uses for an air tool of a sand rammer, a pick or the like in a mine underground roadway construction, wherein the trip preventing air tool pipe junction comprises a pipe junction bamboo joint and a screwed pipe junction, the end portion of the screwed pipe junction is sleeved outside the end portion of the pipe junction bamboo joint, a sealing ring is equipped between the screwed pipe junction and the pipe junction bamboo joint, the screwed pipe junction and the pipe junction bamboo joint are pin connected by a U shaped clamp, the screwed pipe junction is equipped with an anti loosing locking nut and a spring pad. The utility model effectively solves the problem that the connection between an air-hose and the air tool junction is easy to get loose, won't have phenomenon of junction loosing, screw tripping, air pipe dropping or the like caused by the instrument moving, working vibrating, air-hose wiggling or the like, which increases working efficiency and ensuring safe production.
Description
Technical field
The utility model relates to the pressure ventilation pipe joint of pneumatic tool such as pneumatic hammer, pneumatic pick in the underworkings construction of a kind of mine.
Background technique
What known pneumatic tool and air line adopted always is the pipe joint of thread connecting mode, in the work often because of reasons such as instrument moves, air-hose twisting, instrument vibrations, the appearance pipe joint is loosening, screw thread is threaded off, pressure ventilation pipe come off hurt sb.'s feelings, problem such as instrument cisco unity malfunction, bring many hidden danger to safety in production.
Summary of the invention
The purpose of this utility model is that a kind of anti-tripping pneumatic tool pipe joint that is difficult for loosening and releasing will be provided.
The purpose of this utility model is achieved in that this anti-tripping pneumatic tool pipe joint comprises pipe joint ring and screwed pipe joint, the end of screwed pipe joint is enclosed within the outside, end of pipe joint ring, be equipped with seal ring between screwed pipe joint and the pipe joint ring, screwed pipe joint and pipe joint ring connect by the U-shaped bayonet lock, and screwed pipe joint is equipped with anti-loose lock nut and spring washer.
The utility model adopts the Placement of rapid pipe joint, uses the screwed pipe joint that cooperates with it with the pneumatic tool connecting end, disposes an anti-loose lock nut and spring washer simultaneously, and preventing to be threaded, appearance is loosening, the dropout phenomenon.Be connected employing pipe joint ring with air-hose.The Placement of rapid pipe joint is adopted in connection between the joint component, and the sealing of configuration twice O-ring seals connects with the U-shaped bayonet lock.
The utility model has solved the connectivity problem of air-hose and pneumatic tool effectively, because of reasons such as the moving of instrument, operational vibration, air-hose twistings phenomenons such as joint is loosening, screw thread is threaded off, airduct comes off appear no longer, increase work efficiency, guarantee safety in production.
Be described in further detail below in conjunction with accompanying drawing.
Description of drawings
Fig. 1 is an an embodiment's of the present utility model structural representation.
1. pipe joint rings among the figure, 2. screwed pipe joint, 3.U shape card, 4. first O-ring seals, 5. second O-ring seals, 6. anti-loose lock nut, 7. spring washer.
Embodiment
In Fig. 1, this anti-tripping pneumatic tool pipe joint comprises pipe joint ring 1 and screwed pipe joint 2, the end of screwed pipe joint 2 is enclosed within the outside, end of pipe joint ring 1, be equipped with first O-ring seals 4 and second O-ring seals 5 between screwed pipe joint 2 and the pipe joint ring 1, screwed pipe joint 2 and pipe joint ring 1 are by U-shaped card 3 pin joints, and screwed pipe joint 2 is equipped with anti-loose lock nut 6 and spring washer 7.
During use, only need the anti-tripping pneumatic tool pipe joint of plug, can make pneumatic tool and air-hose reliably, be connected apace, improved working efficiency.
Joint component is made simple, and convenient the use is safe and reliable.
