The utility model provides a kind of civil aircraft suitcase hinge, comprising: rocker arm and base, rocker arm below is provided with mounting hole and camshaft, base below is rotatably installed with threaded adjusting shaft, another end of threaded adjusting shaft is rotatably installed in the middle of camshaft, the middle part of base is fixedly installed by rocker arm pivot through mounting hole, rocker arm forms four-bar linkage by camshaft and connecting rod, limiting block is integrated in base, set the minimum opening angle of case door.The hinge system of the utility model is through the innovative "axial compression+radial decoupling" design concept, combined with modular adjustable structure, while ensuring high reliability, realizes the accurate control of case door movement and the convenience of installation and maintenance, breaks through the technical bottleneck that aviation level hinge high reliability and small size are difficult to be compatible, has been successfully applied to multiple civil aircraft luggage compartment system, and has the technical versatility of extending to spacecraft hatch mechanism.

The application discloses a sliding door lock system and relates to the technical field of sliding door lock arrangement. The sliding door lock system comprises an outer opening assembly, an inner opening assembly and a lock body. The outer opening assembly comprises a base, an outer opening handle arranged on one side of the base, a pin shaft arranged in the base, a first torsion spring arranged on the pin shaft and an outer opening rotating arm arranged on one side of the base. The inner opening assembly comprises an inner opening bottom plate, an inner opening rotating arm arranged on one side of the inner opening bottom plate, a rotating shaft arranged in the inner opening bottom plate and an inner opening handle arranged on one side of the rotating shaft. The application has the beneficial effect of omitting the conversion link of the inner opening device and directly controlling the lock body by the inner and outer opening handles. In order to realize the function, the outer opening handle assembly is improved to connect two cables to synchronously control the unlocking functions of the two lock bodies. A newly developed inner opening handle assembly is composed of a handle, a rotating shaft, a bottom plate, a rotating arm and other components and connects two cables to control the unlocking functions of the two lock bodies.

The application provides a door lock mechanism and a dishwasher adopting the same. The door lock mechanism comprises an execution mechanism and a trigger mechanism cooperating with the execution mechanism. The execution mechanism comprises a small load mechanism, a large load mechanism, a locking body and a switching device. The trigger mechanism comprises a driving mechanism, a push rod and a latch. The driving mechanism is connected to the push rod and can drive the push rod to move. The front end of the push rod is provided with the latch which cooperates with the locking body. The small load mechanism and the large load mechanism act on the locking body to provide the locking force of the latch. The switching device changes the acting mode of the small load mechanism and the large load mechanism on the locking body to realize the size switching of the locking force of the latch. The small load mechanism and the large load mechanism act on the locking body through the switching device, the opening and closing doors and the locking state have different load forces, the operation feeling is optimized, the fingers and other parts of the operator are prevented from being clamped when the door is automatically closed, the operator is protected, and the safety hazard is eliminated.

The utility model discloses a turning tongue structure of a lock. The problems that an existing turning tongue transmission structure is complex and unreliable in action are solved. The device comprises a shell, the turning tongue body is arranged in the shell, and the turning tongue body has a first state in which the turning tongue body linearly reciprocates relative to the shell and a second state in which the turning tongue body relatively rotates when the turning tongue body is opened; the turning tongue limiting piece is arranged in the shell and used for limiting turning of the turning tongue body; the turning tongue body is in linear sliding fit with the turning tongue limiting piece when being limited and turned by the turning tongue limiting piece; and the limiting elastic piece is arranged in the shell, is connected with the tongue turning limiting piece and has a movement trend of driving the tongue turning limiting piece to tend to the first position. The turning tongue has the advantages that due to the arrangement of the turning tongue body, the turning tongue body can rotate freely after the turning tongue limiting piece is unlocked, door opening and door closing are facilitated, time and labor are saved, operation is easy, the turning tongue body can achieve the door locking function through locking and limiting of the turning tongue limiting piece, the structure is simple, opening force is small, and the adaptation range is wide.
