Description
Technical field
The utility model relates to a kind of quick-detachable lock device, particularly a kind of airtight quick-detachable lock device on aircraft.
Background technology
The main cabin of present generation aircraft, particularly passenger plane and transport plane cargo hold all adopt pressure cabin to design, and the air-tightness of aircraft is one of key content of aeroplane structure design.Because the equipment on aircraft needs often to safeguard, airframe often offers and variously safeguards lid, lid needs often to open, and in order to improve its maintainability, saves maintenance time, and lid lock needs quick-release.Generally utilize pressure-tight box to ensure air-tightness in open region in the lid of air-tight section, non-hermetically sealed quick-detachable lock is connected within the scope of pressure-tight box mouth frame, take lid clear opening space like this, the use of operating personal and maintenance tool is impacted, thus have influence on the maintainability of aircraft, increase maintenance time.In order to improve maintainability, connect the airtight quick-detachable lock of lid outward at pressure-tight box opening range, the quick-detachable lock of current air standard only has HB6867 " band bushing pin nail quick-detachable lock " can meet quick-release and airtight requirement.But airtight tin hat and the lock housing of " band bushing pin nail quick-detachable lock " adopt Welding to get up; welding process is complicated; poor reliability; be greater than 4mm to lid and mouth frame connection interlayer thickness requirement, comformability is poor, and lock body mainly bears axial tension by termination pin; rainwater easily flows into lock body from lock pin nail; make the perishable damage of lock body, and lock body needs after damaging whole lock to change, maintenance cost is high.
Summary of the invention
The utility model solve technical matters: provide a kind of reliability high, be convenient to safeguard, adaptable air-tightness quick-detachable lock.
The technical solution of the utility model: a kind of airtight quick-detachable lock device; comprise airtight tin hat 1, quick-detachable lock nut 3, quick-detachable lock screw 5 and quick-detachable lock push rod 6; airtight protective case 1 is fixed on fast removing nut 3; quick-detachable lock screw 5 is axially having through hole; quick-detachable lock push rod 6 is installed in the through hole of quick-detachable lock screw 5, it is characterized by: airtight protective case 1 and quick-detachable lock nut 3 are together fixed on mouthful mount structure by the form of riveted joint.
One as the technical program is improved, quick-detachable lock push rod 6 is column, when quick-detachable lock screw 5 having flat recess 12 quick-detachable lock push rod 6 end thereof contacts to gripping mechanism, the other end is positioned at the top bottom quick-detachable lock screw 5 flat recess 12, one end complete locked time, the other end is positioned at the bottom of flat recess 12.The program combines the custom of aviation field on the one hand, have employed the structure of flat recess, once can complete simultaneously and unlocks and remove step, improve dismounting efficiency.
The beneficial effects of the utility model: compared with traditional approach, advantage one of the present utility model is: adopt airtight protective case 1 and quick-detachable lock nut 3 to be together fixed on mouthful mount structure by the form of riveted joint, riveted joint form is simple, and reliability is high; Two is do not affect by lid thickness of interlayer, strong adaptability; Three are quick-detachable lock screws 5 is oval head, and quick-detachable lock push rod 6 is installed in the through hole of quick-detachable lock screw 5, and quick-detachable lock screw 5 and quick-detachable lock nut 3 adopt to be threaded and effectively prevent entering of rainwater, raising lock body service life; Four is adopt riveted joint form, is convenient to change after lock body structure damages, and improves maintainability, reduces maintenance cost.
Accompanying drawing explanation
Fig. 1 is airtight quick-detachable lock device schematic diagram;
Fig. 2 is quick-detachable lock screw oval head flat recess schematic diagram;
Wherein, 1 airtight tin hat, 2 quick-detachable lock clamps, 3 quick-detachable lock nuts, 4 springs, 5 quick-detachable lock screws, 6 quick-detachable lock push rods, 7 back-up rings, 8 packing rings, 9 lid mouth frames, 10 lid cover plates, 11 rivets, 12 flat recesses.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
This airtight quick-detachable lock device is by airtight tin hat 1, quick-detachable lock screw assembly, quick-detachable lock nut assembly three part forms, wherein quick-detachable lock screw assembly is by quick-detachable lock screw 5, quick-detachable lock push rod 6, back-up ring 7 and packing ring 8 form, quick-detachable lock nut assembly is by quick-detachable lock nut 3, quick-detachable lock clamp 2, spring 4 forms, airtight tin hat 1 is riveted on lid mouth frame 9 with quick-detachable lock nut assembly by rivet 11, the air-tightness of structure is ensured by the riveted joint form between airtight tin hat and mouth frame, quick-detachable lock screw assembly is fixed in lid, quick-detachable lock nut assembly and airtight tin hat 1 are fixed on mouthful mount structure, quick-detachable lock screw 5 is threaded connection through lid cover plate 10 and quick-detachable lock nut 3, when quick-detachable lock locks, the spring 4 installed bottom quick-detachable lock nut 3 promotes quick-detachable lock clamp 2 and to snap in bottom quick-detachable lock screw 5 in cross recess, ensure that quick-detachable lock is reliably locked.Use spiral shell cutter to insert in flat recess 12 when opening lid and turn quick-detachable lock screw assembly, quick-detachable lock push rod 6 is promoted when spiral shell cutter inserts in flat recess 12, quick-detachable lock push rod 6 promotes quick-detachable lock clamp 2 and exits cross recess bottom quick-detachable lock screw 5, and after unlocking, quick-detachable lock screw could be back-outed smoothly.Quick-detachable lock screw 5 adopts oval head screw head simultaneously, screw head has flat recess 12, screw head is in the past avoided to adopt the shortcoming of cross notch inefficacy easy to wear, quick-detachable lock screw 5 has through hole, quick-detachable lock push rod 6 is installed in through hole, quick-detachable lock push rod 6 is positioned on bottom quick-detachable lock screw 5 flat recess 12 when locked, and quick-detachable lock push rod 6 is positioned at the top of quick-detachable lock screw 5 oval head with the hole of quick-detachable lock screw 5, can effectively prevent entering of rainwater.
