Problems solved by technology

[0002]The lock hook is a commonly used locking device for aircraft doors. The friction force when the lock hook is locked and unlocked directly affects the design of the power source of the mechanism. If the power source is wrong, if it is too small, it will not be possible to open or close the hatch, if it is too large, it may cause damage to the hatch mechanism

Embodiment Construction

[0026] The specific implementation manner of the present invention will be further described below in conjunction with the accompanying drawings.

[0027] see figure 1 , The present invention is a shackle kinematics type selection test device including a test bracket, a shackle mounting seat 3, a lock seat mounting seat 8, an adjustable collar 2 and a supporting collar 4. Described test support comprises base plate 1, pillar 5 and upper cover plate 6, and described pillar 5 is installed on the four corners of base plate 1, and lock seat mounting base 8, lock hook mounting base 3 and upper cover plate 6 are installed sequentially on pillar. The adjustable collar 2 is installed on the pillars 5 at the four corners between the lock hook mounting base 3 and the bottom plate 1, and passes through the lock base mounting base 8. By replacing the adjustable bushing 2, the height can be adjusted. The support collar 4 is installed on the pillars 5 at the four corners between the lock h...

Abstract

The invention relates to the field of aircraft cabin door mechanism design and test, in particular to a model selection test device for an aircraft cabin door latch hook. The model selection test device comprises a test bracket, a latch hook mounting seat (3) and a latch seat mounting seat (8). The test bracket comprises a bottom plate (1), support columns (5) and an upper cover plate (6), the support columns (5) are mounted at four corners of the bottom plate (1), the lock seat mounting seat (8), the lock hook mounting seat (3) and the upper cover plate (6) are sequentially mounted on the support columns, a toothed lock seat (9) is arranged in the middle of the lock seat mounting seat (8), and a latch hook mounting part is arranged in the middle part of the latch hook mounting seat (3). According to the invention, different test effects can be achieved by replacing the adjustable sleeve ring and replacing the module, different lock hooks are tested, the most matched lock hook is finally selected, repeated design is avoided, the research and development cost is reduced, and the device has high practical application value.

Description

technical field [0001] The invention relates to the field of design and test of an aircraft door mechanism, in particular to a type selection test device for an aircraft door lock hook. Background technique [0002] The lock hook is a commonly used locking device for aircraft doors. The friction force when the lock hook is locked and unlocked directly affects the design of the power source of the mechanism. Once the power source is selected wrongly, the door cannot be opened or closed if it is too small. If it is too large, it may cause damage to the hatch mechanism. In order to design a power source that meets the requirements, avoid repeated design, and reduce research and development costs, a selection test of the kinematics of the lock hook is required. Contents of the invention [0003] The purpose of the present invention is to provide a test device with good compatibility and strong versatility, capable of testing different lock hooks, and meeting the selection req...
