Specific embodiment
Below in conjunction with attached drawing, specific embodiments of the present invention will be described in further detail.
It is provided by Fig. 1 to Fig. 8, the present invention includes cabinet 1 and locking chamber door 10, and the left rear inner wall of cabinet 1 is equipped with vertical
The first locating slot 11, there is horizontal the second upright camera bellows 2 at rear portion in cabinet 1, and the left end of the second camera bellows 2 is placed in the first locating slot
In 11, the right side wall and the right inner wall of cabinet 1 of the second camera bellows 2 have interval, and spacing distance is greater than the left and right of the first locating slot 11 deeply
Degree;Tank wall right part is equipped with vertical rectangular through-hole before cabinet 1, is fitted with the first camera bellows 4,4 rear portion of the first camera bellows in rectangular through-hole
Left end is equipped with the second locating slot 12,12 snap-fit of vertical seamed edge and the second locating slot of 2 front right end of the second camera bellows;
There is the spacing board 14 between chamber door 10 and the first camera bellows 4 on the preceding tank wall of cabinet 1, has after spacing board 14 vertical
The first rotating shaft 9 being fixed in cabinet 1 is equipped with spiral arm 6 on the medial surface of the chamber door 10 of cabinet 1, and the other end of spiral arm 6 is through sleeve
13 are sleeved in first rotating shaft 9, constitute the structure that chamber door 10 rotates in first rotating shaft 9 through spiral arm 6;It is wrapped on sleeve 13
Arc lock tongue 8 outside sleeve 13 and concentric with first rotating shaft 9, arc lock tongue 8 are rotated with sleeve 13;First camera bellows, 4 left side
There is arc groove corresponding with arc lock tongue 8 on the outer edge surface of wall, when chamber door 10 is closed, it is recessed that composition arc lock tongue 8 is placed in arc
In slot, the structure that the first camera bellows 4 is locked in cabinet 1;The second shaft of one end 7 of arc lock tongue 8 is fixed on spiral arm 6,
Constitute the structure that arc lock tongue 8 rotates on spiral arm 6 through the second shaft 7, the leading edge face of the right side of chamber door 10 and the first camera bellows 4
When contact, arc lock tongue 8 is completely disposed at outside arc groove.
In order to guarantee the locking effect of the first camera bellows 4, the extrados of the arc lock tongue 8 is equipped with multiple card holes, more
It is respectively provided with thrust spring 16 in a card hole, there is the sliding roller 15 being installed in card hole outside thrust spring 16, constitutes sliding rolling
The structure that son 15 is contacted through thrust spring 16 with arc groove;When arc lock tongue 8 screws in back-out in arc groove, sliding rolling
Son 15, always with arc groove Elastic Contact, ensure that during opening and closing chamber door 10, arc under the action of thrust spring 16
Real-time the first camera bellows of locking 4 of shape lock tongue 8.
In order to reach better hidden effect, the first storage tank that can be extracted up and down is fitted in first camera bellows 4
5, the second storage tank 3 that can control extraction is fitted in second camera bellows 2.
The present invention is in use, by the door-lock opening chamber door 10 on chamber door 10, and arc lock tongue 8 is with spiral arm 6 along first at this time
Shaft 9 is rotated and is screwed out inside arc groove, and the sliding roller 15 being arranged on 8 extrados of arc lock tongue is acted in thrust spring 16
Lower and arc groove Elastic Contact, the first camera bellows 4 is by real-time locking.
When chamber door 10 fully opens, arc lock tongue 8 is screwed out in outside arc groove completely, and the first camera bellows 4 is inside cabinet 1
Unlock, and the leading edge face contact of the right side of chamber door 10 and the first camera bellows 4 at this time form the external locking to the first camera bellows 4, make
First camera bellows 4 can not be removed.
Arc lock tongue 8 is turned out 90 degree counterclockwise along the second shaft 7 and closes chamber door 1, the first camera bellows 4 is complete at this time
Unlock, file access operations can be carried out by extracting camera bellows 4 out outward.
First camera bellows 4 is fully drawn out except cabinet 1 and is opened chamber door 10, the second camera bellows 2 is slid to the right until completely
The first locating slot 11 of the left rear inner wall of cabinet 1 is slid out, the second camera bellows 2 can be removed carry out file access operations at this time.
In order to further enhance concealment, the first storage tank 5 that can be extracted up and down is fitted in first camera bellows 4,
The second storage tank 3 that can control extraction is fitted in second camera bellows 2.
After file access, the second camera bellows 2 is made uprightly to be placed in the inside of cabinet 1 and its left end insertion cabinet 1 is left inside
In first locating slot 11 of wall rear end, chamber door 10 is closed, by 1 inside of the first camera bellows 4 insertion cabinet until its leading edge face and cabinet 1
Leading edge face is perfectly aligned;Chamber door 10 is fully opened, arc lock tongue 8 is inwardly rotated up into arc lock along the second shaft 7 clockwise
Tongue 8 is adjacent to sleeve 13, closes chamber door 10, and arc lock tongue 8 is rotated along first rotating shaft 9 with spiral arm 6 and screwed in arc groove at this time
Portion, the sliding roller 15 being arranged on 8 extrados of arc lock tongue under the action of thrust spring 16 with arc groove Elastic Contact,
One camera bellows 4 is by real-time locking.
Since the sliding roller 15 on the extrados of arc lock tongue 8 is left with the first camera bellows 4 under the action of thrust spring 16
Arc groove Elastic Contact on side wall, and the arc-like inner band of the arc-like outer band of arc lock tongue 8 and arc groove and first rotating shaft 9
It is arranged concentrically, thereby may be ensured that in the state that arc lock tongue 8 is adjacent to sleeve 13, during closing or opening chamber door 10,
First camera bellows 4 is real-time locking state.
In order to reach better hidden effect, when chamber door 10 is closed completely, the leading edge face of the cabinet 1 and described first
The leading edge face of camera bellows 4 is in same plane or forms continuous curve surface.
Structure of the invention is exquisite, and camera bellows is all linked with one another in cabinet, is difficult to find that this secrecy box has camera bellows structure at a glance.Together
When, the hidden arc lock tongue in hinge arrangement is difficult to be penetrated, after arc lock tongue is opened, since the blocking of chamber door is made
With camera bellows still can not be opened under chamber door opening state, it is necessary to could further be unlocked after closing chamber door, to greatly enhance
The fascination of this secrecy box, has ensured the safety of the file information.
