Description
Technical field
The invention belongs to field of mechanical technique, relate in particular to a kind of handle and return middle reset attachment automatically.
Background technology
The trim handle is the component part of flight control system, in conventional aircraft passenger cabin maneuvering system, the forward and backward bar handle of aviator, handle gear equal controller power output, displacement or other electric signal by mechanical linkage, hinge, realize gear conversion, system's control, sometimes according to functional requirement, after manual force discharges, discharge reset force by the elastic element that has compressed, make the handle get back to initial middle position automatically.Reset attachment had following defective during existing handle returned:
One, owing to reasons such as the gap of mechanical system, skimming wears, mechanism's instability, relatively poor to the repetitive positioning accuracy of initial position, influence the handling quality of aircraft;
Two, owing to adopt the physical constructions of many group spring resets, not only conformability is not so good, and weight and structure are generally bigger;
Three, be subjected to the restriction of mechanical drive leverage, influence the design-calculated alerting ability of aircraft cabin layout;
Four, maintainability is bad, need handle, thereby influence work efficiency.
Summary of the invention
A kind of repetitive positioning accuracy height, the handling quality that the objective of the invention is to overcome above-mentioned shortcoming and provide is good, simple in structure, the handle of reliable operation and simple operation return automatically in reset attachment.
Purpose of the present invention and solve its technical problem underlying and realize by the following technical solutions:
Reset attachment during handle of the present invention automatically returns comprises handle, rotating shaft, base, goes up locating piece, retracing spring, locating piece, locating piece down that wherein: hole on the handle and rotating shaft cylindrical interference fit are rigidly connected; Rotating shaft is a step size garden post, and its post center, big garden is provided with blind hole, and spring, steel ball are contained in the blind hole, and the detent on the locating piece cooperates with steel ball; Rotating shaft is passed circular arc dead slot on the base and locating dowel pin and is clipped in respectively between locating piece and the following locating piece in two grooves, is provided with retracing spring between last locating piece and the following locating piece; Axle passes locating piece successively, locating piece, base, handle are fixed on the locating piece by pin down.
Reset attachment during above-mentioned handle returns automatically, wherein: bearing is housed on the handle, and axle passes the bearing on the handle.
Reset attachment during above-mentioned handle returns automatically, wherein: the detent on the locating piece is the semicircle straight trough.
The present invention compared with prior art, has tangible beneficial effect, by above technical scheme as can be known, rotating shaft built-in spring, steel ball and locating piece groove play the initial middle position positioning action, and locating dowel pin cylindrical and upper and lower locating piece half slot closely cooperate and also can play the initial alignment effect simultaneously; Even long-time the use, small amount of wear appears in locating dowel pin, under the effect of retracing spring pretension, the tight clamping and positioning pin of upper and lower locating piece semicircle cylindrical, thereby guarantee the accuracy requirement of handle initial alignment, long-term placement can not produce slippage, thereby the accuracy of positioning height.In addition because forward, the handle that rotates backward produces restoring force by same spring, forward, the equal angular that rotates backward, the feel of operating handle changes not obvious, handling quality is good.By locating with spring, steel ball, independent spring reset mode realize that the conversion of stick control gear, control back reset certainly, and compact conformation is simple, reliable operation.
The specific embodiment of the present invention is provided in detail by following examples and accompanying drawing thereof.
