The technical solution that the utility model is taken is as follows:
A kind of aircraft airspeed pipe dynamic pressure detection test connector, the connector include connecing mouth, neonychium, main body, protective case
Cylinder, blanking cover, the first O-ring and the second O-ring；
The main body is the revolving body of both ends open, and front end is fixedly connected with mouth is connect, and rear end is threadedly coupled with blanking cover, described
Blanking cover is tube-in-tube structure, and protection sleeve is sleeved in blanking cover, and the step of protection sleeve excircle front end is limited by blanking cover front end face,
And protection sleeve rear end is stretched out by blanking cover rear end；It is described to connect the neonychium that protection pitot pitot aperture is equipped with inside mouth；The master
It is equipped with the first O-ring in the inner circumferential groove of body front end, while rotating blanking cover that the second O-ring is extruded in body rear inner periphery is convex
Between end face and protection sleeve front end face, the first O-ring and the second O-ring are contacted with pitot outer circumference surface, realization body
The sealing of inner peripheral surface and pitot.
Further, the connector further comprises third O-ring, and third O-ring and the second O-ring are disposed side by side on master
Between body back end inner circumference raised head face and protection sleeve front end face.
Further, the connector further comprises circlip, and the circlip is mounted in body rear inner groovy, and is located at
The rear that main body is threadedly coupled with blanking cover.
The utility model has the advantages that
1, the utility model is easy to operate, and pitot is inserted into connector, rotates blanking cover, pushes protection sleeve extruding second
O-ring, the deformation locking of the second O-ring squeeze pitot and realize swelling sealing, can guarantee intracavitary sealing together with the first O-ring,
And O-ring, neonychium and protection sleeve are directly contacted with pitot, the scratch for avoiding pitot is damaged, and sealing performance is steady
Determine, using reliable, protection is effective.The utility model compact structure is simple, does not need excessive extensive space, improves pitot
The accuracy and working efficiency of dynamic test.
2, the utility model further comprises third O-ring, is continuously arranged side by side with the second O-ring, increases O-ring
Deformation quantity improves the sealing reliability of connector.
3, the utility model further comprises circlip, and circlip can prevent blanking cover from surprisingly falling off, and guarantees the peace of a whole set of connector
Quan Xing.
Detailed description of the invention
Fig. 1 is the integrally-built semi-cutaway of the utility model.
Wherein, 1- connects mouth, 2- neonychium, 3- main body, 4- protection sleeve, 5- blanking cover, 6- circlip, the first O-ring of 7-, 8- the
Two O-rings, 9- third O-ring.
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
A kind of aircraft airspeed pipe dynamic pressure detection test connector is present embodiments provided, as shown in Figure 1, including connecing mouth 1, protecting
Protection pad 2, main body 3, protection sleeve 4, blanking cover 5, circlip 6, the first O-ring 7, the second O-ring 8 and third O-ring 9.
Mouth 1 is connect for connecting cooperation with detection device sebific duct, connects the neonychium for being equipped with protection pitot pitot aperture inside mouth 1
2, neonychium 2 uses polytetrafluoroethylene (PTFE).
Main body 3 is the revolving body of both ends open, adopts and is formed from aluminium, and portable construction, 3 front end of main body is threadedly coupled with mouth 1 is connect,
3 rear end of main body is threadedly coupled with blanking cover 5, and sealant is smeared in threaded connection place.
Blanking cover 5 is tube-in-tube structure, and protection 4 excircle front end of sleeve is equipped with step, and protection sleeve 4 uses polytetrafluoroethylene (PTFE).
