Description
Technical field
The utility model relates to a kind of blocking device, particularly relates to a kind of compression type blocking device of the protective door for there being uprising gas defence requirement engineering, airtight blast door and sealed door.
Background technology
Protective door, airtight blast door, sealed door are widely used in people's air defense, colliery chamber etc. to have special door that is uprising and gas defence requirement engineering, for the door of this kind of engineering, the effect of locking is not only door start or stop, the sealing function having more opposing shock and stop pernicious gas to infiltrate is the vitals of door system.Usually, there is the blocking device that the protective door of uprising requirement, airtight blast door, sealed door use, general employing ramp type lockhole or Wedge type tapered end, during locking, tapered end extrudes by inclined-plane the mode coordinated with lockhole and locks, mainly contain following three types: the first, the cylindrical tapered end of rocking handle and trapezoidal obturator hernia inclined-plane sliding pressure formula blocking device.Its operating principle makes tapered end enter trapezoidal obturator hernia by rotation crank and slides along trapezoidal inclined plane, by the locking of tapered end extruding lockhole.Its advantage is that structure is simple, easy to operate; Shortcoming is that tapered end and lockhole bevel friction hoisting capacity are large, and the controllability of cooperation is poor, and locking effect is poor.The second, rocking handle linkage tapered end and trapezoidal obturator hernia inclined-plane sliding pressure formula blocking device.Its operating principle drives tapered end to enter obturator hernia by rotation crank linkage and extruding locking of sliding along trapezoidal inclined plane.Its advantage be up and down, left and right or all tapered end by linkage combination interlock, many tapered ends locking can be implemented simultaneously, structure is relatively simple, easy to operate; But there is the shortcoming identical with the first.The third, worm-and-wheel gear Wedge type tapered end and square locking stopple pressure type blocking device.Its operating principle is first closed by door, and Wedge type tapered end is filled in obturator hernia by rear rotation worm-and-wheel gear, locked by wedge tapered end jam-packed locking hole wall.Its advantage is that locking stroke is comparatively large, and hoisting capacity is less, reliably sealed; Shortcoming is that structure is comparatively complicated, and the locking used time is more, and device is comparatively heavy, is generally used for Double-wing door.
Summary of the invention
The purpose of this utility model is the deficiency overcoming above-mentioned prior art, provide that a kind of locking property is reliable, structure is simple, easy to operate, can effectively the laminating degree of adjustment doors and the compression type blocking device of hoisting capacity.
The utility model comprises lock body and snap close.Lock body comprises latch receptacles, latch shaft, tapered end, axle sliding pin and handle; Snap close comprises lock catch block, snap close pressing plate and regulates pad; Lock body is arranged on door leaf, and snap close is arranged on doorframe and corresponding position, lock body position, and both form blocking device jointly.Latch receptacles comprises bed plate and two blocks of pedestal plates and axle sliding pin seat, and axle sliding pin seat is arranged on the pedestal plate of adjacent snap close side, and pedestal plate is provided with wears axis hole, and axle sliding pin seat is provided with pinned hole.Latch shaft is provided with axle chute, and one end of the adjacent snap close of latch shaft is provided with triangle or rectangular cam tapered end, and latch shaft is arranged in latch receptacles through the axis hole of wearing on pedestal plate.Handle is arranged in latch shaft.Axle sliding pin is arranged on axle sliding pin seat by the pinned hole on axle sliding pin seat, and axle sliding pin lower end is stretched in the axle chute in latch shaft, controls the slippage of latch shaft when latch shaft is rotated.The end face of axle sliding pin seat is provided with axle sliding pin flap plate, from capping pinned hole above, controls axle sliding pin and do not depart from axle chute in locking opening-closing process.Snap close pressing plate and adjustment pad are arranged on lock catch block.
Described latch receptacles be assembly welding shaping or adopt integral casting forming.Described cam tapered end is welded on locking axle head, or is screwed at locking axle head, described latch shaft and cam tapered end or adopt single-casting.Described axle sliding pin flap plate bolt or screw are arranged on axle sliding pin seat.At locking states cam tapered end compact lock button.
While closedown door leaf, rotate clockwise handle, latch shaft is rotated thereupon, latch shaft, by axle sliding pin and the common restriction being located at the axle chute in latch shaft, to the slippage of snap close direction while rotation, makes tapered end move to correspondence position after snap close, be rotated further handle, make the tapered end be located in latch shaft compress the snap close pressing plate be located on lock catch block, complete the locking of door, reach closedown object door leaf and doorframe being fitted tightly locking.When rotating backward handle, tapered end departs from snap close, and latch shaft resets, and completes the unlatching of door.
The utility model is in the process of sealed and door capable of being opened, and latch shaft slip, efficiently solves the matching problem of tapered end and snap close, achieves the sealed object of compression of tapered end compression snap close; In addition, according to the requirement of door leaf and the airtight laminating degree of doorframe and hoisting capacity, the adjustment pad of configuration snap close, effectively can ensure laminating degree and the seal of door, and control the hoisting capacity of locking preferably.The utility model structure is simple, dependable performance, and flexible adjustment is easy to operate, can effectively the laminating degree of adjustment doors and hoisting capacity, and locking effect is good.
