Description
Technical field
The present invention relates to people's air defense technical field, in particular to a kind of closed guard gate.
Background technique
Civil air defense constructions and installations is typically all manufacturing products for both peacetime and wartime us engineering, usually has a large amount of personnel and equipment to enter and leave, wartime requirement is closed
The closed guard gate of entrance prevents shock wave and poison gas from entering inside civil air defense constructions and installations.To guarantee the closed guard gate of entrance in wartime energy
The effect of shock wave is enough kept out, the threshold on a prominent ground will be generally arranged in closed guard gate, for bearing the impact on door leaf
Wave pressure, but this threshold to usually personnel and vehicle discrepancy bring big inconvenience.
In this regard, the Chinese patent that Authorization Notice No. is 103266838 A of CN, the applying date is on May 21st, 2013 discloses
A kind of Threshold-free civil defense door of doorway, includes door leaf, doorframe, locking and hinge page, and the lower part of door leaf is equipped with sealed beam and sealing
Beam elevating mechanism, sealed beam is convertible sealed beam, including being fixedly connected on the free bearing at the door leaf back side, being hingedly connected on free bearing
Rocking bar, be fixedly connected on rocking bar flip beam, be fixed on flip beam with ground cooperation ground face seal, Yi Jigu
Be scheduled on flip beam with door leaf cooperation door leaf sealing element, sealed beam elevating mechanism include inverted L shape vertical link, crank,
Axle bed, bearing, sealed beam elevating mechanism transmission shaft, reversing speed variator and sealed beam go up and down handle.
Wherein, the closed guard gate in above-mentioned patent is moved up and down by locking handwheel to control upper and lower tapered end, to complete people
The locking and unlocking of anti-door, and closed guard gate is sealed by the overturning that rotary seal beam goes up and down handle control flip beam, such as
This locks a door although the problem of realizing at entrance without threshold and needs to carry out by operation twice with flip beam, more numerous
It is trivial.
And if to realize to the synchronously control of locking transmission shaft and sealed beam elevating mechanism transmission shaft, focus on
While tapered end completes locking, it is ensured that door leaf sealing element on flip beam and ground face seal needs respectively with the door body of closed guard gate
Abutting is adjacent to ground, and closed guard gate itself is not the very high product of required precision, it therefore, can not be good in design
The initial point of good control sealed beam elevating mechanism transmission shaft rotation is adjacent to or complete in advance in this way, being easy to appear cannot achieve
The problem of at being adjacent to, and cannot achieve and be adjacent to the problem of will cause poor sealing, and fulfil ahead of schedule to be adjacent to and will lead to upper and lower lock
Head can not be moved to best lock position.Cause improved closed guard gate for the more demanding of precision, significantly increases life
The cost for producing and debugging, and the rejection rate of finished product is also higher.
Summary of the invention
The object of the present invention is to provide a kind of closed guard gate, control can be synchronized to tapered end and flip beam, and complete
It can be adjusted at after installation, it is ensured that locking and sealing effect.
Above-mentioned technical purpose of the invention has the technical scheme that
A kind of closed guard gate, including interlock assembly and seal assembly, the interlock assembly include locking transmission shaft, the sealing group
Part includes sealed beam elevating mechanism transmission shaft, and the locking transmission shaft is synchronous with the transmission between centers setting of sealed beam elevating mechanism to be passed
Component is moved, is provided with rack segments on the locking transmission shaft, the Synchronous Transmission component includes:

Sliding block is provided with and rack segments meshed gears on the sliding block；
Locking adjusts component, rotates for unidirectionally controlled gear；
Telescopic oscillating bar, one end are hingedly connected on sliding block, the input terminal connection of the other end and reversing speed variator.
So set, when locking and sealing two effects in one there is deviation when, can pass through locking adjust component control
Sliding block processed sliding on locking transmission shaft is (wherein, described in the application unidirectionally controlled to refer to that locking adjusts component and is able to drive
Gear rotation, and gear can not reversely drive locking to adjust component movement), in this way, will drive sealed beam elevating mechanism transmission shaft
Rotation, changes its initial point, and moving sliding block according to the actual situation, to suitable position locking to can be completed synchronous with sealing.?
Complete after adjusting, when needing to lock a door, it is mobile that rotation locking runner will drive locking transmission shaft, by upper tapered end and lower lock head respectively to
Upper and lower ends are released, and the locking of closed guard gate is completed；At the same time, the movement for being latched transmission shaft will drive the swing of telescopic oscillating bar,
To drive the input terminal of reversing speed variator to rotate, the sealed beam elevating mechanism that the rotation of input terminal will drive output end is passed
Moving axis rotation, it is on the contrary when unlock so that flip beam be driven to downwardly turn over.
Further preferably are as follows: the locking adjusts component and includes actuator, the driving bevel gear connecting with actuator and drive
The dynamic bevel gear of dynamic bevel gear engagement, with the worm screw of dynamic bevel gear synchronous rotation, the turbine that is engaged with worm screw, the turbine
It is rotated with gear synchronous.
So set, dynamic bevel gear can be driven to rotate, to drive snail after actuator drives driving bevel gear rotation
Bar rotation, and then turbine is driven to rotate, and turbine and gear are to rotate synchronously, therefore, gear can also occur to turn at this time
It is dynamic, to walk about on rack segments with movable slider.
Further preferably are as follows: the actuator is a driving handwheel.
So set, convenient for control driving bevel gear rotation.
Further preferably are as follows: the reversing speed variator includes shell and the bevel gear set in shell.
So set, realize switching operation, meanwhile, it can be gone up and down according to the moving distance and sealed beam of locking transmission shaft
Rotational angle needed for mechanism driving axis realizes that the two can be liked to tend to mutually unify by the setting of transmission ratio.
Further preferably are as follows: the closed guard gate includes internal hilar plate and external door panel, and the interlock assembly is set on internal hilar plate and outside
Between door-plate.
So set, interlock assembly is set between internal hilar plate and external door panel, interlock assembly can be hidden, more
Beauty, and the protecting effect to interlock assembly can be played, longer service life is made it have, reliability is higher.
Further preferably are as follows: the locking handwheel on the interlock assembly is exposed to outside internal hilar plate, one end is through internal hilar plate
Axis connection is driven with locking.
Further preferably are as follows: the sliding slot of one with sliding block cooperation are provided through on the internal hilar plate.
So set, guiding is capable of providing first, secondly, easy to operate.
Further preferably are as follows: the telescopic oscillating bar includes outer bar and one end is inserted in the interior bar in outer bar.
So set, making telescopic oscillating bar that can freely stretch during the swing, and structure is simple.
Further preferably are as follows: clearance fit between the outer bar and interior bar
So set, dust is not easily accessible between outer bar and interior bar, resistance can be smaller during simultaneous retractable.
In conclusion the invention has the following advantages:
