Problems solved by technology
In addition to the transmission mechanism of the handle itself, this type of handle also needs to arrange a special cover and cover lock. There are many parts and the design is complicated; It needs to occupy more structural space; in addition, when operating the handle, the cover lock and cover must be opened first, and the installation, adjustment, inspection and maintenance are complicated.

Embodiment Construction
[0022] This design can be used to solve two problems through a set of multi-position one-in-one handle control mechanism that can realize the initial rotation angle non-transmission: First, the handle should be able to realize and maintain three states for different task requirements: initial position, Handle ready for working position, working position. Second, the handle should be able to switch between the initial position and the ready-to-work position without actuating the task unit. This design fulfills the requirements of different handle states, guarantees the requirements of compact axial layout and less parts, and meets the load-bearing stability of the cantilever mechanism.
[0023] In order to keep the handle operating mechanism flush with the shape of the mounting base, the handle operating mechanism maintains the handle in its initial position through a clamping device, see figure 1 . When manipulating the handle, first push the handle to rotate, so that the ha...

The invention provides a multi-position-in-one handle control mechanism. The multi-position-in-one handle control mechanism comprises a first support 4, a second support 5, a steel cable 6, a spline shaft 3, a handle 2, a fan-shaped assembly 1, a lock key 7 and a spring 8, wherein the fan-shaped assembly 1 is a fan-shaped structural part, a groove is formed in the fan-shaped side face of the fan-shaped assembly 1, one end of the steel cable 6 is fixed in the groove of the fan-shaped assembly 1, and the other end of the steel cable 6 is connected with a task unit; a radial spline groove is formed in the circle center of the fan-shaped assembly 1; one end of the spline shaft 3 is provided with a spline, the other end of the spline shaft 3 is an optical shaft, and the spline end of the splineshaft 3 is fixed in the spline groove of the fan-shaped assembly 1; the first support 4 is of a flat plate structure, a boss is arranged in the center of the first support 4, a through hole is formedin the boss of the first support 4, a boss is arranged in the center of the second support 5, a through hole is formed in the boss of the second support 5, and a cavity structure is formed between the first support 4 and the second support 5.
Description
technical field [0001] The present application relates to the structural design of an aircraft, in particular to a multi-position-in-one handle manipulation mechanism. Background technique [0002] Common handles on the outside of the machine body are usually arranged in the maintenance hatch, and there are only two states of initial placement and rotating work. In addition to the transmission mechanism of the handle itself, this type of handle also needs to arrange a special cover and cover lock. There are many parts and the design is complicated; It needs to occupy more structural space; in addition, when operating the handle, the cover lock and cover must be opened first, and the installation, adjustment, inspection and maintenance are complicated. Contents of the invention [0003] The multiple-in-one handle control mechanism provided by this product meets the requirements of different handle states, ensures the requirements of compact axial arrangement and fewer part...
