Abstract
The invention relates to the technical field of aviation, in particular to a spring return type high-box locking mechanism. The spring return type high-box locking mechanism consists of a cabinet body, a high box, a jack, a return spring, a button rod, a locking block, a drawer bottom plate, a button head, a handle, a boss, a locking spring and a locking block cavity, wherein the cabinet body and the drawer bottom plate form a drawer cavity, and the high box is positioned in the drawer cavity. The locking block cavity is a blind hole positioned in the vertical direction in the drawer bottom plate, the jack is a blind hole positioned in the horizontal direction in the drawer bottom plate, and the locking block cavity is communicated with the jack. The locking block is positioned in the locking block cavity, one end of the button rod is inserted into the jack, and the other end of the button rod is the button head integrated with the button rod; and the return spring is sheathed on the button rod. In the spring return type high-box locking mechanism, the locking state of the high box is not eliminated due to high-frequency vibration of a plane body, and the reliability and the durability are higher.
Description
Technical field
The present invention relates to the aeronautical technology field, particularly relate to the high case locking mechanism of a kind of spring reset formula.
Background technology
The emergency escape channel side of existing airline carriers of passengers is provided with the metallic combination cabinet that the car of dining together from a common dish, locker and file cabinet are one.All be provided with at the top of combination sideboard and be used to deposit the high case of article of being of little use.For the ease of taking off, the drawer-type structure that the combination of these high casees and combination sideboard all adopts is fixing high case, and the outer edge of combination sideboard is provided with the catch that an end has rotating shaft, and rotating shaft and combination sideboard are fixed, and catch can rotate around the shaft.At ordinary times, catch is rotated to vertical direction, slides to prevent high case; In the time of need taking high case, catch is rotated to level.But above-mentioned catch only relies on the stiction between itself and the rotating shaft to reach that it is of living in vertically or level fixing.Such scheme has following technological deficiency:
Prolonged and repeated the rotating around the axis of catch can cause the two mutual wearing and tearing, and long-term wearing and tearing can reduce the frictional force between the two, thereby can reduce the stability of catch.Comparatively violent dither can take place in aircraft in take-off process; Under this vibration; Catch can have bigger angle of slope and take off process middle machine body integral body, in case catch self rotates to horizontal direction around the shaft toward the horizontal direction rotation under himself action of gravity; Its barrier effect disappears; High case can skid off from combination sideboard and impinge upon under its action of gravity on the cabin floor, and such accident can cause damage to cabin and high case on the one hand, if high on the other hand case pounds the crew or the passenger can cause even more serious injury.
Summary of the invention
The present invention is for solving the deficiency of prior art, provides a kind of and both had higher stability, the stability of high case locking is not received the influence of aircraft vibration, the crew is unlocked easily and takes out the high case locking mechanism of spring reset formula of high case.
The scheme that solves technical problem of the present invention is:
The high case locking mechanism of spring reset formula is made up of cabinet, high case, jack, back-moving spring, button spindle, lock dog, drawer-bottom board, button head, handle, convexity, locking spring and lock dog chamber.Wherein, cabinet and the horizontal fixed drawer-bottom board in cabinet has constituted the drawer chamber, and high case is in the said drawer chamber and with the drawer chamber and is in active relationship.Bottom, the outer end of high case have with high case be holistic handle.Leave a segment distance between the end face in the upper surface of high case and the drawer chamber, this distance is the 1/5-1/4 of the height of high case.The lock dog chamber is that to be positioned at drawer-bottom board, vertical direction, cross section be the blind hole of rectangle.The opening in lock dog chamber is positioned at the upper surface of drawer-bottom board.Jack is to be positioned at blind hole drawer-bottom board, horizontal direction, and the opening of jack is positioned at the outer end of drawer-bottom board.The diameter of the opening part of jack is less than the interior diameter of jack.The vertical center line in lock dog chamber and the axial line of jack intersect vertically.The lock dog chamber communicates with jack.Lock dog is that the upper surface is the block on an inclined-plane.Lock dog is in the lock dog chamber and with the lock dog chamber and is in active relationship.Be provided with the locking spring between the bottom surface in the bottom surface of lock dog and lock dog chamber.Button spindle is a cylinder, and an end of button spindle inserts in the jack, and the other end of button spindle and button spindle are that holistic, diameter is greater than button spindle diameter, discoidal button head.Button spindle be in have on the outer wall of the part in the jack with button spindle be holistic convexity.The opening of button spindle and jack is in active relationship.On the opening part of jack and the button spindle between the button head, be with back-moving spring.Under the not stressed situation in the upper surface of lock dog, the top on the inclined-plane of lock dog is higher than the upper surface of drawer-bottom board, and the bottom on the inclined-plane of lock dog is lower than the lower limb of jack.
In the time of need high case being taken out from the drawer chamber; Only need axially to press button head along button spindle; The inclined-plane that the inner of button spindle presses lock dog moves down lock dog; When the beveled top end of lock dog was lower than the upper surface of drawer-bottom board, lock dog disappeared to the barrier effect of high case, and the crew spurs handle and just can smoothly high case be pulled out.
In the time of need high case being put back to the drawer chamber; Only need directly high case to be pushed away in the drawer chamber; Move down under the pressure on edge, bottom in high case, the inclined-plane of lock dog and the lock dog chamber of withdrawing fully in; After the process beveled top end of lock dog of the outer face of high case, the beveled top end of lock dog stretches out the upper surface of drawer-bottom board again under the promotion of locking spring, and high case is locked again.
Adopt such scheme, compared with prior art, the present invention has following marked improvement:
1. because the present invention is not that the frictional force through rotating shaft and catch realizes as prior art to the maintenance of the lock-out state of high case; But realize locking through stopping of lock dog to high case; Such lock-out state does not disappear because of the dither of airframe, therefore has higher reliability and persistence.
2. because the present invention realizes the releasing of lock function through pressing the button head, it is very convenient to operate.
3. owing to leave a segment distance between the inner top surface in the end face of high case and said drawer chamber, can supply the not high enough crew of height like this when taking high case, high case hauled out, compared with prior art, play labour-saving effect more with certain gradient.
