It is upper to pivot to open container 1 or pivot to close container 1 downwards.Certainly, door leaf 20 can also other forms (such as side is opened
Door) it is arranged on other faces of casing 3, depending on the quantity specific size of visual door leaf 20 of hinge 30, the utility model
This is not construed as limiting.
Locking device 10 for container 1 includes the first locking device 10a and the second locking device 10b.First locking
Device 10a includes the first locking bar 100, the first tapered end 101 and the first lock 401.Second locking device 10b includes the second locking bar
200th, the second tapered end 201 and the second lock 402.
First locking bar 100 and the second locking bar 200 are installed on door leaf 20 by mounting seat 300 respectively, and can be rotating around each
From axis rotation in the mounting seat 300.First locking bar 100 and the second locking bar 200 respectively with where the hinge 30 of door leaf 20
Side be arranged in parallel, and distance of first locking bar 100 away from hinge 30 is less than distance of second locking bar 200 away from hinge 30.
First locking bar 100 is respectively arranged at two ends with the first tapered end 101, and corresponding with the first tapered end 101 on casing 3
Position, is fixedly installed the first lock 401 coordinated with the first tapered end 101 respectively.Specifically, as shown in Figure 4 A and 4 B shown in FIG.,
One tapered end 101 is hook-like configuration, including the body 101a that is fixed around the first locking bar 100 and from body 101a radially outward
Prominent hook section 101b.First lock 401 is the postive stop baffle with the correspondence position of the first tapered end 101 for being soldered to casing 3.Its
In, the outline when coordinating with the first lock 401 away from the side of the first lock 401 of hook section 101b is generally arc-shaped,
And the installation of the ultimate range less than casing 3 of the axis o'clock away from the first locking bar 100 on the outline of hook section 101b is set
There is the minimum range of axis of the surface at the first lock 401 away from the first locking bar 100.
As shown in Fig. 2 in the state of the closing of door leaf 20, the first tapered end 101 is at position shown in dotted line with the first locking bar
100 turn clockwise, and after certain angle is turned over, hook section 101b is stopped by the first lock 401 causes the first locking bar 100 cannot
Continue to rotate, now, the first locking device 10a lockings.During unblock, operation the first locking bar 100 drives the first tapered end 101 counterclockwise
Rotation, hook section 101b departs from the first lock 401.Due on the outline of hook section 101b o'clock away from the first locking bar 100
The ultimate range of axis is less than the most narrow spacing of axis of the surface being provided with the first lock 401 of casing 3 away from the first locking bar 100
From, therefore during the first tapered end 101 is rotated counterclockwise with unblock with the first locking bar 100, the first tapered end 101 is outermost

20 effect.Therefore the releasing process of the first locking device 10a does not interfere with the closed mode of door leaf 20.
Preferably, the first lock bar handle 102 is provided with the first locking bar 100, in order to be grasped to the first locking bar 100
Make.The relevant position on the surface of door leaf 20 is provided with the first lock bar handle seat 501.When the first locking device 10a is in locking
During state, the first lock bar handle 102 is close to the surface of door leaf 20 and is fixed by the first lock bar handle seat 501, so that the first locking
Device 10a maintains the lock status.Such design simultaneously can also be avoided because the first lock bar handle 102 protrudes from container 1
Outside cause danger, it is convenient container 1 to be lifted or other operations.
Second locking bar 200 is respectively arranged at two ends with the second tapered end 201, and corresponding with the second tapered end 201 on casing 3
Position, is fixedly installed the second lock 402 coordinated with the second tapered end 201 respectively.Specifically, as fig. 5 a and fig. 5b,
Two tapered ends 201 are claw type structure, including the body 201a that is fixed around the second locking bar 200 and from body 201a outwardly
Claw type portion 201b.Second lock 402 includes that base portion 402a and deck portion 402b, base portion 402a are used to be soldered to casing 3
Surface, deck portion 402b is arranged on base portion 402a, to coordinate with the second tapered end 201.The end of claw type portion 201b is set
The ultimate range of axis of the portion away from the second locking bar 200 is more than base portion 402a of the axis of the second locking bar 200 away from the second lock 402
Surface distance, and there is base portion 402a certain width to cause projections of the claw type portion 201b on the surface of casing 3
Fall in the width range of base portion 402a.
As shown in figure 3, due to claw type portion 201b axis of the end away from the second locking bar 200 ultimate range more than the second lock
The distance on the surface of base portion 402a of the axis of bar 200 away from the second lock 402, when the second locking device 10b is in unblock shape
During state, the outermost end of claw type portion 201b is caused under the active force of the second lock 402 against the surface of base portion 402a, the
Two locking bar 200 drives door leaf 20 away from the segment distance of casing 3 one, and door leaf 20 cannot be completely closed.
When needing the second locking device 10b of locking, in the state of as shown in Figure 3, operation the second locking bar 200 drives second
The rotate counterclockwise of tapered end 201, the outermost end of claw type portion 201b is no longer abut against base portion 402a, now door leaf 20 in self gravitation or
In the presence of external force completely closed state is moved to casing 3.Continue the second locking bar of rotate counterclockwise 200, the second tapered end 201
Claw type portion 201b contact and be resisted against on the deck portion 402b of the second lock 402, the second locking bar 200 cannot continue rotation, this
When, the second locking device 10b lockings.During unblock, operation the second locking bar 200 drives the second tapered end 201 to turn clockwise, claw type portion
The deck portion 402b of 201b and the second lock 402 departs from, after rotating through certain angle, the ends contact pedestal of claw type portion 201b
The outer surface of portion 402a.Because the ultimate range of the axis of the end away from the second locking bar 200 of claw type portion 201b is more than the second locking bar
The distance on the surface of base portion 402a of 200 axis away from the second lock 402, therefore second locking bar that turns clockwise ought be continued
When 200, base portion 402a gives claw type portion 201b power with direction generally outwards, makes the second locking bar 200 drive door leaf 20 to open
And away from a certain distance of casing 3, when claw type portion 201b is substantially vertical with base portion 402a, distance reaches maximum, the second lock
Tight device 10b is unlocked completely.In this way, the tapered end of claw type structure is designed causes that the second locking device 10b locks in unblock with second
Seat 402 produces interaction forces, is so conducive to the smooth unlatching of door leaf 20, while being also possible to prevent in locking state the
Two tapered ends 202 loosen because of vibrations or other reasonses and cause unblock.

Two locking device 10b are in the state of unblock, due to the claw type structure design of the second tapered end 201 so that the second tapered end 201 and the
Two locks 402 interact, and produce the power F along the opening direction of door leaf 20.Due to the second tapered end 201 and the second locking bar 200,
Rigidity is between two locking bars 200 and door leaf 20, the locking bar 100 of door leaf 20 and first and the first locking bar 100 and the first tapered end 101
Connection, therefore power F produced by the second tapered end 201 can act to whole locking device 10 with door leaf 20, it is all so as to cause
As door leaf 20 deforms, the first locking bar 100 and the clamping of the first lock 401 are even damaged or the second tapered end 201 and second of aggravation
The situations such as the abrasion between lock 402 occur.
Therefore, need first to unlock the first locking device 10a for locking device 10, during unblock, then unlock the second locking dress
Put 10b；And need first to lock the second locking device 10b when locking, then lock the first locking device 10a.Thus, according to this practicality

Or unblock.
Preferably, it is provided with postive stop baffle 103 with the corresponding position of the second lock bar handle 202 in the first locking bar 100.When
When first locking device 10a and the second locking device 10b are in locking state, the second lock bar handle 202 is limited baffle plate 103
Block spacing, cannot now carry out operating the second lock bar handle 202.Only when the first locking device 10a is unlocked, postive stop baffle
103 turn over certain angle with the first locking bar 100 when no longer blocking the second lock bar handle 202, can just be operated, so as to prevent
The maloperation of the second locking bar 200 is unlocked by force when the first locking device 10a is in locking state and causes to damage.
It is further preferred that when container 1 is bulk goods type container, during opened door leaf 20, goods in case
Easily gone out from case in the presence of self gravitation, so as to bring danger to the positive operator of door leaf 20, for safety,
Generally require from side opened door leaf 20.Therefore, the second lock bar handle 202 is disposed proximate to container 1 with door is installed
