Abstract
The invention pertains to mechanical structure design, relating to a drawbar type unlock mechanism of a hatchdoor. In the unlock mechanism, an outer cylinder is sheathed outside an inner cylinder, a ball groove is arranged at the lower part of the inner wall of the outer cylinder, and a ball hole is arranged at a position of the lower part of the inner cylinder corresponding to the ball groove of the outer cylinder; an inner cylinder plug is arranged at the lower part of the inner cylinder, a spring is arranged between the upper part of the inner cylinder plug and the inner cylinder, the lower end of the inner cylinder plug is provided with two ball grooves arranged symmetrically, two balls are blocked in the ball hole of the inner cylinder and the ball groove of the outer cylinder symmetrically, a blocking cover is arranged at the lower end of the inner cylinder, a pin penetrates through the central hole of a dustproof cover and propped up to the lower end of the inner cylinder plug, a pressure spring is sheathed between a pin connecting shaft and the blocking cover, a rotating shaft of a handle is hinged on the outer cylinder, and one end head of the handle is hinged with the pin. The ground unlock mechanism of the hatchdoor is simple, convenient, safe and easy-operating for ground maintenance and improves the reliability of important parts, thus facilitating the demounting and installation of ground crew and maintainers.
Description
Technical field
The invention belongs to the frame for movement design, relate to a kind of drawbar type unlock mechanism of hatchdoor.
Background technology
The hatch door unlocking mechanism mainly adopts form of structure such as fixedly connected pin form of interlock and the built-in lock of hydraulic actuator at present.As on the Boeing-737 aircraft, adopt the type of attachment of anchor tip, use link gear; When this form of structure is installed adjustment at hatch door, need special location and measurement, and use frock, when guaranteeing the hatch door closing gap, also will guarantee the pretightning force of hatch door; When safeguarding adjustment, must disconnect the pull bar that is connected with hatch door; Hatch door is responsible for opening and is received to a front door shared hydraulic actuator in both sides on Boeing 777 aircrafts, and on hatch door arrive to be received or during extended position, hydraulic actuator internal lock latch-up structure is safeguarded when adjusting operation, also will disconnect the pull bar that is connected with hatch door.The locking mechanism of these two kinds of hatch doors is analyzed from the angle of operation and maintenance, and opening and install to the ground maintenance personnel of hatch door brings very big inconvenience.Except the maintenance tool of needs specialty, also need to understand structure design principle herein, this gives the very high technical requirements of attendant.Brought very big inconvenience during this external processing emergency, can not satisfy requirement the quick emergency processing of emergency.
Summary of the invention
The purpose of this invention is to provide a kind of drawbar type unlock mechanism of hatchdoor that a kind of working service is convenient, manipulation is simple and direct.Technical solution of the present invention is, the urceolus socket outer tube, the outer tube inner wall bottom has ball grooves, the corresponding position of the ball grooves of inner core bottom and urceolus has ball hole; The bottom of inner core is equipped with the inner core stopper, between the top of inner core stopper and inner core spring is housed, there is the ball ball groove of two symmetrical distributions inner core stopper lower end, two ball symmetries are stuck in the ball grooves of the ball hole of inner core and urceolus, the lower end of inner core is equipped with blanking cover, and the centre bore that pin passes dust cap withstands on inner core stopper lower end, socket stage clip between pin connecting axle and the blanking cover, the rotating shaft of handle is hinged on the urceolus, and the termination and the pin of handle are hinged.
Ball ball groove on ball grooves on the described outer tube inner wall and the inner core stopper is deep-slotted chip breaker.
Advantage that the present invention has and beneficial effect, the position of the ball in the connecting rod inner core is mainly locked in the design of hatch door of the present invention ground unlocking mechanism by hatch door, make the inner core of hatch door lock connecting rod and urceolus produce mechanical clamping stagnation and automatically lock, when pin promotion inner core stopper moves, ball is offset between inner core and the stopper, urceolus and inner core are thrown off, and can move freely, and lock is opened.Adopt this kind hatch door form of unblanking, make ground maintenance simple, quick, safe, easy to operate, and improved the reliability of important spare part.Dismantle easily and install for ground crew and maintenance mans' inspection work provides.
Description of drawings
Fig. 1 structural representation of the present invention;
Fig. 2 locking-in state schematic diagram of the present invention;
Fig. 3 is a unlocking condition schematic diagram of the present invention.
The specific embodiment
Urceolus 1 is the main support body among the present invention, and there is jointing the lower end, links to each other with hatch door, and is socketed in outside the inner core 2, and inner core and urceolus are slidingly connected, and there is joint the upper end, links to each other with link gear; The outer tube inner wall bottom has ball grooves 10, and the ball grooves 10 corresponding positions of inner core 2 bottoms and urceolus 1 have ball hole 11; The bottom of inner core 2 is equipped with inner core stopper 6,2 of the top of inner core stopper 6 and inner cores are equipped with spring 3, there is the ball ball groove 12 of two symmetrical distributions inner core stopper 6 lower ends, in the ball hole 11 that two ball 4 symmetries are stuck in inner core 2 and the ball grooves 10 of urceolus 1, the lower end of inner core 2 is equipped with blanking cover 8, the centre bore that pin 5 passes dust cap 9 withstands on inner core stopper 6 lower ends, socket stage clip 13 between pin 5 connecting axles and the blanking cover 8, the rotating shaft of handle 7 is hinged on the urceolus 1, and the termination and the pin 5 of handle 7 are hinged.
Two kinds of work user modes of the present invention:
Locking state: hatch door lock of the present invention connects as one with hatch door, can make hatch door link together with other component of undercarriage with the pretightning force state of the best by adjusting the length of pull bar.During locking, the position skew by ball 4 reaches the effect of stop, and under the effect of spring 3, remains at this state blocking between inner core 2 and the urceolus 1.
Unlocking condition: after handle 7 touched pin 5 jack-up inner core stoppers 6, ball 4 glided along ball grooves 10 in the chamber, by ball hole 11, arrived ball ball groove 12, and ball 4 is offset to inner core stopper 6, and inner core 2 can draw back, and reaches the state of throwing off hatch door.
