Adjustable hook lock for aviation hatch door
The invention discloses an adjustable hook lock for an aviation hatch door. The adjustable hook lock comprises a case body and a lock body, wherein the lock body is rotationally connected to one end of the case body through a first torsion spring; the two ends of the first torsion spring separately abut against the case body and the lock body; the first torsion spring is used for enabling the casebody to rotate relative to the lock body; the case body is equipped with a trigger piece through a second torsion spring; the two ends of the second torsion spring separately abut against the triggerpiece and the case body; the second torsion spring is used for enabling the trigger piece to rotate relative to the case body; the trigger piece is used for pulling or releasing the lock body so as to complete locking or unlocking; the lock body comprises an adjusting mechanism and a locking hook; and the adjusting mechanism is used for adjusting the length of the locking hook. In the adjustablehook lock for the aviation hatch door, the length of the locking hook can be adjusted so as to achieve wide applicability. The length of the locking hook can be adjusted through the arrangement of theadjusting mechanism, so that the lock is suitable for hatch doors of various types. The lock can be adjusted to a suitable length according to installation conditions so as to achieve suitable stressconditions, so that the service life of the lock can be effectively prolonged and the application range can be expanded.
本发明公开了一种航空舱门用可调钩子锁，包括壳体和锁体，锁体通过第一扭簧与壳体的一端转动连接，第一扭簧的两端分别抵在壳体上和锁体上，第一扭簧用于壳体相对锁体进行转动，壳体上通过第二扭簧安装有触发件，第二扭簧的两端分别抵在触发件上和壳体上，第二扭簧用于触发件相对壳体进行转动，触发件用于拉住或松开锁体进而完成锁闭或开启；锁体包括调节机构和锁钩，调节机构用于调节锁钩的长度；本发明的锁钩长度可以调节，适用性广；通过设置调节机构调节锁钩的长度能够适应多种型号的舱门，可以根据安装工况对锁进行调节至合适的长度以达到合适的受力条件，能够有效延长锁具的寿命，以此扩大适用范围。
