Abstract
The utility model belongs to the field of aviation test, and relates to a clamping joint, in particular to a clamping joint for airplane airspeed head static pressure inspection, which comprises a first rubber gasket 1, a movable pressing sheet 2, a screw 3, a nut 5 and a fixing frame 6. A handle 4 is arranged at one end of the screw 3; a flared connection structure 7 is arranged at the other end of the screw 3; the end of the screw 3 with the flared connection structure penetrates through the nut 5 to be connected with the movable pressing sheet 2 in a flared limit mode; and the flared connection structure does not project over the inner surface of the movable pressing sheet 2. The clamping joint is simple in structure, convenient in operation and reliable in work, repeated adjustment of clamping positions is not needed in operation, clamping operation is completed once, clamping and fixing are reliable, convenience is brought for ground crew to inspect the air tightness of an airspeed head, and the inspection efficiency of the airplane airspeed head is improved.
Description
Technical field
The utility model belongs to field of aviation measurement and test, relates to a kind of clamping, the clamping of especially a kind of aircraft airspeed pipe static pressure inspection.
Background technology
Clamp when being used for aircraft airspeed pipe airtight test, clamp the right cylinder at pitot baroport place, form pitot hydrostatic seal air cavity, carry out the airtight test of air cavity.The function of clamping directly influences the check result of pitot, and its usability influences the maintenance efficiency of air speed system.The aircraft Atmosphere System is carried out the air speed hierarchical design for improving the measuring accuracy of pitot, and straight section increases such as pitot have designed crimp ring, and baroport leaves on corresponding corrugated surface.The outfield uses former static pressure to clamp, and leaks air, the phenomenon of sealing difference; During use, to adjust the static pressure inlet clamped position back and forth, adjust the clamping attitude that clamps movable plate, eliminate gas leakage, simultaneously, the insufficient strength of the screw rod of clamping, nut stripped thread occurs, presss from both sides not tight phenomenon in the use, work brings inconvenience to aircraft maintenance, and the reliable operation degree is low, practicality is not good enough.
Summary of the invention
The purpose of this utility model: provide a kind of convenient, aircraft airspeed pipe static pressure inspection flexibly to clamp, this clamp easy to operate, the functional reliability height.
The technical solution of the utility model:
The inspection of a kind of aircraft airspeed pipe static pressure is clamped, and comprises first rubber blanket 1, movable compressing tablet 2, screw rod 3, nut 5, fixed mount 6, it is characterized in that:
Described screw rod 3 one ends have handle 4, the other end has enlarging syndeton 7, described screw rod 3 has enlarging syndeton 7 one ends and passes nut 5 and be connected with movable compressing tablet 2, and type of attachment adopts enlarging spacing, and the enlarging syndeton is not protruded the inside surface of movable compressing tablet 2;
Described first rubber blanket 1 is bonded on the movable compressing tablet 2;
Described nut 5 usefulness screws 9 are fixed in the fixed mount lower end;
Described fixed mount 6 cross sections are the inverted U structure, are stained with second rubber blanket 8 in the U type bottom of fixed mount 6;
Preferably, described screw rod 3 and nut 5 are processed by steel.
Advantage of the present utility model: the utility model is simple in structure, easy to operate, reliable operation, operation does not need to repeat to adjust clip position, the clamp operation one-time-reach-place, clamp, fix reliably, make things convenient for the ground crew to carry out the operation of pitot airtight test, improved the checking efficiency of aircraft airspeed pipe.

Wherein, 1 first rubber blanket, 2 movable compressing tablets, 3 screw rods, 4 handles, 5 nuts, 6 fixed mounts; 7 enlarging syndetons, 8 second rubber blankets, 9 screws.
Embodiment: below in conjunction with accompanying drawing the utility model is described in detail, sees also Fig. 1 and Fig. 2.The inspection of a kind of aircraft airspeed pipe static pressure is clamped, and comprises first rubber blanket 1, movable compressing tablet 2, screw rod 3, nut 5, fixed mount 6, it is characterized in that:
Described screw rod 3 one ends have handle 4, the other end has enlarging syndeton 7, described screw rod 3 has enlarging syndeton 7 one ends and passes nut 5 and be connected with movable compressing tablet 2, type of attachment adopts enlarging spacing, the enlarging syndeton is not protruded the inside surface of movable compressing tablet 2, thereby when guaranteeing that joint clamps pitot, 1 distortion of first rubber blanket is even, and the snap-in force of whole movable compressing tablet 2 is evenly distributed;
Described first rubber blanket 1 is bonded on the movable compressing tablet 2;
Described nut 5 usefulness screws 9 are fixed in the fixed mount lower end, and nut 5 is fixedlyed connected by screw 9 with fixed mount 6, form the rigid frame of clamping;
Described fixed mount 6 cross sections are the inverted U structure, and fixed mount 6U type is stained with second rubber blanket 8 in the bottom;
Preferably, described screw rod 3 and nut 5 are processed by steel.
