Summary of the invention
Purpose of the present invention has proposed a kind of new quick-detachable lock structure and using method thereof for the defective that exists in the prior art problem and deficiency.
A kind of quick-detachable lock, contain lock box, locking closure, dead bolt, spring, locking bar, slide block, button, it is characterized in that locking bar is a L structure, dead bolt is fixed on an end of locking bar, spring housing is connected on the locking bar behind the dead bolt and is embedded in the locked groove of lock box, the other end of locking bar is connected with slide block, slide block is embedded in the chute of lock box, described slide block has an inclined-plane corresponding with the chute inclined-plane of lock box, described button is a wedge structure, and limited location pin on it, this button are embedded between slide block and the lock box chute inclined-plane, the upper surface of button stretches out the corresponding opening of locking closure, and locking closure snaps onto on the lock box.
A kind of using method of above-mentioned quick-detachable lock is the maintenance lid inboard that above-mentioned quick-detachable lock is installed in aircraft, and dead bolt is with respect to the scalable contact of lid frame, and releasing the button of quick-detachable lock is corresponding at lid outer openings place.
The another kind of using method of above-mentioned quick-detachable lock is the luggage-boot lid inboard that above-mentioned quick-detachable lock is installed in aircraft, and dead bolt is with respect to the scalable contact of luggage hatch cover frame, and releasing the button of quick-detachable lock is corresponding at luggage-boot lid outer openings place.
The invention has the advantages that, adopted to hit and bumped the formula method for closing, reduced operating procedure, and can select the locking closure of respective thickness to satisfy matching requirements according to lid frame thickness, to obtain to open and close flexibly operation, avoid occurring catching phenomenon operating personnel are brought inconvenience, profile is hidden attractive in appearance.
Below in conjunction with the embodiment accompanying drawing this application is described in further detail.

Number description: 1. lock box; 2. locking closure; 3. spring; 4. locking bar; 5. slide block; 6. button; 7. spacer pin; 8. dead bolt; 9. lid frame; 10. lid; 11. exterior skin; 12. securing member; 13 lid lockholes
The specific embodiment
Referring to accompanying drawing 1, lock box 1, locking closure 2 are selected LY12-BCZYU sheet material in the enforcement; Spring 3 is selected HB3-1-0.5 * 5 * 22II; Locking bar 4 is selected the 30CrMnSiA bar; Slide block 5 and button 6 are selected LY12-BCZYU sheet material; Alignment pin 7 is selected the 30CrMnSiA bar; Dead bolt 8 is selected LY12-BCZYU; Sheet material securing member 12 is selected (bolt 4A1-22-4 * L, packing ring 4A1-175-4 * 8 * 1, nut 4A-41-4).Except spring 3 and securing member 12, make by machining.
The assembly relation of the application's quick-detachable lock as shown in Figure 2, locking bar 4 is L-type bar structures, locking bar 3 interts in the pilot hole at lock box middle part, its front end is fixed with dead bolt 8, spring 3 is socketed on the locking bar behind the dead bolt and is embedded in the locked groove of lock box 1, the other end of locking bar 4 be plugged in the connecting hole of slide block 5, but make slide block, locking bar and dead bolt be called the one synchronizing moving, slide block 5 is embedded in the chute of lock box one side, described slide block 5 has an inclined-plane corresponding with the chute inclined-plane of lock box, forms a triangular notch; Described button 6 is wedge structures, and limited location pin 7 on it, this button are embedded in the triangular notch between slide block and the lock box chute inclined-plane; Locking closure 2 snaps onto on the lock box, offers the opening corresponding with button position on the locking closure 2, and the upper surface of button 6 stretches out the corresponding opening of locking closure, and the spacer pin 7 of button is subjected to the restriction of locking closure 2, makes button be unlikely to break away from lock box.
Below introduce the operating principle of this quick-detachable lock, under the normal condition, dead bolt stretches out lock box, the upper surface of button 6 stretches out the corresponding opening of locking closure, when pressing button 6 perpendicular to the lock box body, button 6 will promote slide block 5 and slide, and slide block 5 and then drive locking bar 4 and dead bolt 8 Compress Springs are retracted in the lock box dead bolt, remove the lock function of dead bolt; If operating personnel discharge the pressure that is applied on the button 6, compressed spring 3 discharges elastic potential energy, promotes dead bolt 8 and locking bar 4, slide block 5 and button 6 and all resets.
A kind of using method of this quick-detachable lock is as the airplane hatch cover Quick-disassembling device, as shown in Figure 5 and Figure 6, normal conditions the lower flap frame 9 is fixed on the opening inboard of exterior skin 11, lid 10 covers on the lid frame 9, appearance and exterior skin are contour, for lid and lid frame locking position, the application's quick-detachable lock are installed in the inboard of the maintenance lid 10 of aircraft with fixture 12, dead bolt 8 is provided with the lid lockhole 13 that can press the quick-detachable lock button with respect to the 9 scalable contacts of lid frame in lid; The opposite side of lid 10 is connected with the lid frame with the torsionspring (not shown) by hinge.Press like this quick-detachable lock button on the lid, can remove the locking of dead bolt counterpart cover frame, open the maintenance work that lid is carried out aircraft.Finish to safeguard when closing lid, lid 10 is promoted in the lid frame, allow the inclined-plane of dead bolt 8 contact with 9 collisions of lid frame, 9 pairs of dead bolts of lid frame 8 produce active force, cause in the dead bolt Compress Spring retraction lock box, lid is closely withheld on the lid frame, no longer is subjected to active force after dead bolt 8 is fully by lid frame 9, compressed spring 3 discharges elastic potential energy makes dead bolt 8 reset at the inboard of lid frame, realizes closing of lid.
The another kind of using method of this quick-detachable lock is as air baggage hatchcover quick-detachable lock structure with above-mentioned quick-detachable lock, the luggage-boot lid that quick-detachable lock is installed in aircraft is inboard, dead bolt is with respect to the scalable contact of luggage hatch cover frame, and releasing the button of quick-detachable lock is corresponding at luggage-boot lid outer openings place.
