Description
Technical field
The utility model is related to technical field of motors, specifically a kind of Quick connector for air tightness test.
Background technology
To meet the quick air-tightness test request of motor, a kind of quick coupling for motor water nozzle, existing market are needed
On not similar Quick connector for air tightness test.
Therefore, it is necessary to design Quick connector for air tightness test a kind of easy to operation and high reliability.
Invention content
The purpose of the utility model is to overcome the deficiencies of the prior art and provide gas a kind of easy to operation and high reliability
Close property tests quick coupling.
In order to achieve the above object, the utility model is a kind of Quick connector for air tightness test, including movable sleeve, inner sleeve,
Baffle ring, steel ball, rubber pad, sealing ring, it is characterised in that：The end outer sheath of water nozzle be equipped with inner sleeve, inner sleeve close to water nozzle one
Outer sheath is held to be equipped with movable sleeve, movable sleeve is internally provided with cone structure close to one end of water nozzle, and inner sleeve surface is provided with steel ball, steel
The side of ball is contacted with movable sleeve, and the other side of steel ball resists the flange of water nozzle, and the end of water nozzle uses rubber seal, water nozzle
End and inner sleeve between using sealing ring seal.
The other end outer sheath of the inner sleeve is equipped with baffle ring.
Compared with the prior art, the utility model designs Quick connector for air tightness test, and steel ball is controlled by movable sleeve
Activity makes water nozzle be switched fast in pressurize and releasing orientation, is conveniently operated, can singlehanded quick-clamping, using rubber pad and sealing
Enclose dual leakage-preventing, reliability height.The utility model has the characteristics that small, portable.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the packing state schematic diagram of the utility model.
Fig. 3 is the releasing orientation schematic diagram of the utility model.
Specific implementation mode
The utility model is described further in conjunction with attached drawing.
Referring to Fig. 1, a kind of Quick connector for air tightness test of the utility model, including movable sleeve, inner sleeve, baffle ring, steel ball, rubber
The end outer sheath of rubber cushion, sealing ring, water nozzle 6 is equipped with inner sleeve 2, and inner sleeve 2 is equipped with movable sleeve 1 close to one end outer sheath of water nozzle 6,
Movable sleeve 1 is internally provided with cone structure close to one end of water nozzle 6, and 2 surface of inner sleeve is provided with steel ball 4, side and the activity of steel ball 4
1 contact of set, the other side of steel ball 4 resist the flange of water nozzle 6, and the end of water nozzle 6 is sealed using rubber pad 5, the end of water nozzle 6 and
It is sealed using sealing ring 7 between inner sleeve 2.
In order to limit the sliding position of movable sleeve 1, the other end outer sheath of inner sleeve 2 is equipped with baffle ring 3.
Referring to Fig. 2, movable sleeve 1 slides into the right, and movable sleeve 1 pushes down steel ball 4, and steel ball 4 resists 6 flange of water nozzle, and water nozzle is in
Packing state.
Referring to Fig. 3, movable sleeve 1 slides into the left side, and steel ball 4 is released, and water nozzle is in releasing orientation.
The workflow of the utility model, in the initial state, for movable sleeve 1 close to baffle ring 3, steel ball 4 is in half travelling shape
Pressure-maintainingconnector connector is inserted in water nozzle 6 by state, turns right and movable sleeve 1, the cone structure of quill 1 is pushed to squeeze and tighten steel ball 4, steel
Ball 4 is held tightly and fixed water nozzle, 5 sealing tap of rubber pad, 6 end, sealing ring 7 seal side.After completing air tightness test, draw
Dynamic movable sleeve 1 makes it close to baffle ring 3, and steel ball 4, which squeezes, to be unclamped, and steel ball 4 unclamps water nozzle, removes pressure-maintainingconnector connector.
The utility model devises Quick connector for air tightness test, controls 4 activity of steel ball by movable sleeve 1, water nozzle is made to exist
Pressurize and releasing orientation are switched fast, and are conveniently operated, can singlehanded quick-clamping, anti-let out using rubber pad 5 and sealing ring 7 are dual
Dew, reliability are high.The utility model has the characteristics that small, portable.
