The purpose of this utility model and solve its technical problem underlying and realize by the following technical solutions:
Spacing and the release combination mechanism of aircraft throttle lever of the present utility model comprises block, unlock button, and the block support, mounting bracket, wherein: described block is fixed on the block support, and the block support is provided with horizontal limit devices; The block support is flexibly connected by block rotating shaft and mounting bracket, and the two ends of block rotating shaft are positioned at mounting bracket; Vertically pull back spring is positioned at the below of mounting bracket internal stop rotating shaft; The longitudinal spacing screw be positioned at the block rotating shaft the top, be fixed on mounting bracket; Unlock button is fixedly mounted on the block support.
Spacing and the release combination mechanism of above-mentioned aircraft throttle lever, wherein: described horizontal limit devices comprises cross spacing screw, horizontal pull back spring, nut, the cross spacing screw passes the block support, and laterally pull back spring, packing ring, nut sequentially are loaded on the cross spacing screw.
Spacing and the release combination mechanism of above-mentioned aircraft throttle lever, wherein: described horizontal limit devices is two covers.
Spacing and the release combination mechanism of above-mentioned aircraft throttle lever, wherein: described unlock button is threaded connection and is fixedly mounted on the block support.
The utility model compared with prior art has obvious advantage and beneficial effect.By above technical scheme as can be known, block is fixed on the block support, and the block support is provided with horizontal limit devices; The block support is flexibly connected by block rotating shaft and mounting bracket, and the two ends of block rotating shaft are positioned at mounting bracket; Vertically pull back spring is positioned at the below of mounting bracket internal stop rotating shaft; The longitudinal spacing screw be positioned at the block rotating shaft the top, be fixed on mounting bracket; Unlock button is by being fixedly mounted on the block support.in flight course, when throttle lever need to enter the " STOP " position from " slow train " position, the backing pin that is fixed on throttle lever contacts with the vertical surface of block, due to the rotation of the cross spacing screw limit stop support anti-clockwise in horizontal limit devices, throttle lever is limited in " slow train " position, throttle lever can not be got back to the " STOP " position, the capable of being unlocked by pressing button makes the block rotating shaft promote vertical pull back spring and vertically moves down in the groove of mounting bracket, spacing and release combination mechanism moves down block with throttle lever, mobile backstop is lower than the backing pin bottom, this moment, throttle lever can enter from the " STOP " position " slow train " position, throttle lever passes through block homing under the effect of vertical pull back spring afterwards.Just can all throttle levers of mechanical release by the capable of being unlocked by pressing button, and this utility model can vertically move down and around block rotating shaft unidirectional rotation.
In a word, the utility model is spacing and release mechanism integration with throttle lever, a kind of release cocking mechanism that do not need is provided, when entering the " STOP " position from " slow train " position, just can all throttle levers of mechanical release by a unlock button, saved cocking mechanism, simple in structure, number of parts is few, lightweight, cost is low, easy and simple to handle.
