Problems solved by technology

Rotary quick-release locks are easy to use and small in size, but their load-bearing capacity is relatively weak; snap-on quick-release locks can withstand large loads but have a large operating space and opening size; tongue-type quick-release locks have good sealing performance and Greater load carrying capacity, but only for thicker walls
[0004] At present, the connection locks used in aerospace operation covers have disadvantages such as large size, heavy weight, inability to operate with bare hands, openings for both the hole cover and the frame, and inability to seal against rain, which cannot meet the needs of increasingly high-speed military products. Requirements for use; especially for the use of stealth aircraft, the existing connection locks currently cannot meet the low reflection requirements of radar waves, and the locking and opening of the connection lock is extremely inconvenient

Embodiment 1

[0055] Example 1, such as Figure 1-10 As shown, a flap locking device, the flap 1 is hinged to the flap frame 2, the locking device includes at least two locks 3 arranged on the flap, between adjacent locks Connected by the linkage mechanism 4, the opening cover is provided with the same number of lock holes as the number of locks. Locks that operate synchronously through linkage mechanisms cannot use locking grooves as locking mechanisms.

[0056] Such as Figure 13-Figure 14 It is the first type of lock, and the lock 3 includes a lock base 3-1, a driving member 3-2 arranged on the lock base, a swing arm 3-3, a slider 3-5, a support 3-6 and a pressure head, One side of the lock base is provided with a driver socket 311, and the other side is provided with a slide groove 312, the driver is installed in the driver socket, the slider is installed in the slide groove, and the swing One end of the arm is connected to the driver, and the other end is hinged to one end of the sl...

Embodiment 2

[0068] Example 2, such as Figure 11 with Figure 12 As shown, a lock hole 11 is provided on the cover. No matter how many locks are installed on the cover, there is only one lock hole on the cover, and only one lock hole is used to control the switches of all the locks. The lock corresponding to the lock hole can adopt the first type of lock, the second type of lock and the third type of lock, through which the mounting hole of the lock base is riveted with the inner side of the cover, and the protrusion at the bottom of the corresponding lock base cooperates with the lock hole; The installation hole of the lock seat is riveted with the inner side of the cover, and the bottom surface of the lock seat is flush. The first type of lock and the third type of lock can be used, and the lock with a locking mechanism using a locking groove is not allowed.

[0069]The button lock of the present invention includes two states of unlocking and locking. A relatively large and small lock...

Abstract

The invention discloses a cover locking device. The locking device includes at least two locks arranged in the cover. Adjacent locks are connected through a linkage mechanism. At least one lock hole is provided on the cover; the lock includes a lock seat. , driver, swing arm, slider, support and pressure head, the slider is installed in the chute, one end of the swing arm is connected to the driver, the other end is hinged to one end of the slider through a connecting rod, and the support is bent One end of the support is hinged with the lock seat, the middle part is provided with a guide groove, the other end is connected with the pressure head, the other end of the slider is provided with a dial pin, the end of the dial pin extends into the guide groove, and the lock seat is provided with There is a lock seat installation hole connected to the inner surface of the cover; the invention has simple structure, convenient installation and maintenance, small size and light weight, and only needs to operate a lock at the position of the lock hole on the outside of the cover to control the unlocking of all locks inside the cover And locking linkage, convenient and reliable operation, can adapt to the use of regular shape openings and irregular openings.

Description

technical field [0001] The invention relates to a flap locking device, which belongs to the technical field of aircraft flap locks. Background technique [0002] In order to ensure that the airborne equipment on the aircraft is maintained and repaired in a timely manner, a large number of covers need to be provided on the surface of the aircraft. The covers are divided into quick-release covers and non-quick-release covers according to their use characteristics. The quick-release cover usually only needs to be simply pressed or twisted or the entire cover can be opened or closed by using a simple tool. [0003] At present, the fast opening and closing of various flaps used on aircraft can be mainly divided into several types such as rotary screw type, snap button type, hook tongue type, and integral detachable type in terms of mechanism principle and operation mode. Rotary quick-release locks are easy to use and small in size, but their load-bearing capacity is relatively w...
