Specific embodiment
To make the purpose, technical scheme and advantage that the present invention is implemented clearer, below in conjunction in the embodiment of the present invention
Attached drawing, the technical solution in the embodiment of the present invention is further described in more detail.
In order to solve the problems, such as to be proposed in background technology, the present invention devise one kind can ensure hatch door open when it is fixed stably
Gu, Lock safety can good cabin door structure when closing.
As shown in figure 4, the cabin door structure of the present invention includes hatch door installing frame 1, hatch door 2, fixing device 3, left and right two admittedly
Lock 4 and 5 and grip handle lock 6.As shown in figure 5, installing frame 1 is opened on covering, the top edge and installing frame 1 of hatch door 2 are hinged,
Fixing device 3 includes the fixed salient point 31 being arranged on covering 10 and the fixing buckle 32 being arranged on hatch door 2, fixed salient point 31
Coordinate with fixing buckle 32 so that hatch door 2 is fixed when being bonded with hinge axes rotation with covering 10.Left fixing lock 4 and right fixing lock 5
It is arranged on the one end of hatch door 2 away from hinge axes and is distributed in two side angles of hatch door 2, left fixing lock 4 and right fixing lock 5 can be
Hatch door 2 and installing frame 1 are attached, to prevent hatch door 2 from opening.Grip handle lock 6 is arranged on hatch door 2 and adjacent to left fixing lock 4
Or right fixing lock 5 is any, grip handle lock 6 is arranged on the side of left fixing lock 4 in the present embodiment, for limiting turning for left fixing lock 4
It is dynamic.
As shown in Figure 6 and Figure 7, the circle that fixed lobe 32 includes regular polygon firm banking and is connected with firm banking is convex
It rises, firm banking and circular protrusions integral structure.
As shown in figure 8, fixing buckle 31 includes the fixed edge 311 being connected with hatch door 2 and is arranged at consolidating on fixed edge
Surely 312 are blocked, fixing card 312 is circular protrusions 32 as shown in Figure 9 to have reeded elastic construction to block circular protrusions 32
With the cooperation schematic diagram of fixing buckle 31.
As shown in Figure 10 to Figure 12, left fixing lock 4 includes handle 41, handle base 42 and bolt 43, and handle base 42 passes through cabin
The mounting hole set on door 2 is installed on hatch door 2, and handle 41 is relatively fixed through handle base 42 with bolt 43, and bolt 43 can
It is relatively rotated and with installing axially bored line with coordinating to limit the unlatching of hatch door on installing frame with handle 41.
Left fixing lock 4 further includes left side /V cornual plate 44B and the right limit cornual plate 44A that limitation axis pin 43 rotates, left limit
Cornual plate 44B and right limit cornual plate 44A be relatively fixed with hatch door 2 and left limit cornual plate 44B and right limit cornual plate 44A limitation
Hatch door 2 can be opened when 43 rotational angle of axis pin meets the left limitation cornual plate 44B limitations rotation of axis pin 43 and right limitation cornual plate 44A is limited
Hatch door cannot be opened when cotter axis 43 rotates.
Grip handle lock 6 includes finished product lock 61 and cam 62, and finished product lock 61 is relatively fixed with cam 62 and finished product lock 61 can
Cam 62 is controlled to deflect certain angle, two extreme positions of certain angle are respectively first position and the second position, first
Cam 62 and right limit cornual plate 44A cooperations limitation axis pin 43 rotates when putting, and cam 62 does not interfere axis pin 43 to rotate during the second position
To left limit cornual plate 44B.
Such as Figure 13, in the present invention, by increasing respectively when fixed point ensures that hatch door is opened on hatch door and on covering
Position is fixed and is bonded substantially with covering, ensure that it will not interfere with other hatch doors in main body mechanism；It is by replacing PUSH locks
Built-in bolt mechanism, while increase microswitch, when hatch door closes false lock, by display alarm information in cockpit.
A) increase a bolt on covering 10 with the hatch door 2 after fixed open, increase by a sleeve fixture mechanism on hatch door 2
3 coordinate when hatch door 2 is opened with bolt on covering；
The hatch door 2 that the fixing device 3 of hatch door 2 is opened after being fastened with bolt on covering 10 can be fixed on covering 10, grasped
Make simple and fast, fixing device 3 is fixed with hatch door 2 by the way of being spirally connected, and convenient disassembly easy care is replaced；
B) it is handle bolt mechanism to replace PUSH locks, for hatch door is avoided to be opened automatically in the case of unmanned touching after closing
It opens, devises two-stage security function altogether：
The first order is fixing lock：Shaft 43 in fixing lock is closed by rotating with the installing frame of hatch door to match somebody with somebody, and is led to
Limitation cornual plate 44A and the 44B limitation for crossing both sides rotates 43 rotation amplitude, plays the role of locking and opens hatch door.Hatch door 2
Opening process is opposite with latching process.
The second level is grip handle lock 6：It is convex by rotating after the locking for turning to that vertical position realizes hatch door 2 in shaft 43
Wheel 62 can limit the rotation of shaft 43, realize and further lock fixing lock 4, so as to fulfill the two level locking of hatch door 2.
The cabin door structure of the present invention solves fixation problem during hatch door opening, is not interposing at it and occurs to do with passenger door
Relate to, at the same compared with the prior art in security of PUSH lock constructions when adding hatch door locking, there is simple in structure, cost
The advantages that cheap.
The cabin door structure of the present invention has many advantages, such as that support is convenient, simple in structure, security performance is high.
The above is only the optimal specific embodiment of the present invention, but protection scope of the present invention is not limited thereto,
Any one skilled in the art in the technical scope disclosed by the present invention, the change or replacement that can be readily occurred in,
It should be covered by the protection scope of the present invention.Therefore, protection scope of the present invention should be with the protection model of the claim
Subject to enclosing.
