A push-knob type storage disk quick release structure

Abstract

The invention discloses a push-knob type storage disk quick release structure, which belongs to the field of structural design of airborne electronic equipment. The structure can provide a new and reliable idea for the quick release method of the airborne recorder storage disk. The main structural parts include Knobs, knob shafts, knob springs, gear shafts, bolt return springs, upper rack bolts, lower rack bolts, bolt guide rails, gear bearings, stops, etc. When the storage disk is mated with the connector of the chassis, the operator presses down the knob and rotates it 90° counterclockwise, then the lock tongues on both sides of the storage disk retract into the disk body, the constraint between the storage disk and the chassis is released, and the storage disk can be Unplugged smoothly. When inserting the disk again, press down the knob in the same way. When the storage disk is inserted in place, the knob will receive an obvious restoring torque. The operator will rotate the knob clockwise to return to the position according to the torque and let go, and the knob will pop out for a short distance. Indicates that the storage disk is firmly inserted and cannot be pulled out.

Description

technical field [0001] The invention belongs to the field of structural design of airborne electronic equipment, and relates to a quick release structure of a press knob type storage disk. Background technique [0002] The quick disassembly structure has always been the focus and difficulty in the structural design of the storage disk of the airborne recorder. At present, the existing quick release structure adopts the design scheme of the push-and-eject mechanism, and the quick release structure can realize the insertion and removal action by pressing the storage disk itself. However, the structural form of the pressing ejection part determines that it has some problems. Since the card can be inserted and removed by pressing the storage disk itself, when the storage disk is inserted in place, the inertial force generated by the storage disk caused by the harsh vibration environment on the machine may accidentally trigger the pop-up action, resulting in an accident; in addi...

AI Technical Summary

Problems solved by technology

Since the card can be inserted and removed by pressing the storage disk itself, when the storage disk is inserted in place, the inertial force generated by the storage disk caused by the harsh vibration environment on the machine may accidentally trigger the pop-up action, resulting in an accident; in addition, the structure The locking of the storage disk is realized by a unilateral restraint force, which will form a force couple with the inertial force of the storage disk to make the storage disk skew and squeeze between the guide rail, and then there may be jamming, which will make it impossible to press it again. Failure to eject the storage disk

In addition, the functional structure of the push-to-eject mechanism is mainly set on the chassis, and it can only be repaired by disassembling the chassis after a failure occurs, so the maintainability is poor
