Description
Technical field
This utility model relates to a kind of sealed door, particularly relates to the anti-reflective bullet blocking mechanism of a kind of steel structure double-leaf airtight blast door.
Background technology
The locking structure of sealed door of the prior art is relative complex, causes the inconvenience of operation, and properties is outstanding.
Chinese patent 201410040743.1, open a kind of plug-type airtight blast door of steel construction, including door leaf and scroll wheel, doorframe and the sealing joint strip of periphery, locking link gear, outside guide roller mechanism, trench cover plate raises device, and the steel guide rail for scroll wheel motion, door leaf both sides respectively set a set of inner side type leading wheel framework.Inner side type leading wheel framework coordinates locking link gear that the embedded pressing bar entirety that seals on door leaf is embedded or exited in the embedding groove of sealing joint strip, it is ensured that door leaf is opened smoothly.Manual traveling wheel mechanism guarantees light slip when opening of large scale door leaf.Little airtight blast door facilitates a small amount of personnel to come in and go out.This structure is relative complex, and using effect is general.
Utility model content
This utility model mainly solves the deficiencies in the prior art, it is provided that a kind of compact conformation, easy to operate, the anti-reflective bullet blocking mechanism of the steel structure double-leaf airtight blast door that sealing property is strong.
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:
The anti-reflective bullet blocking mechanism of a kind of steel structure double-leaf airtight blast door includes doorframe, described doorframe is provided with left-hand door fan and right door leaf, respectively by hinge mechanism phase locating rotation between described doorframe and left-hand door fan, between doorframe and right door leaf, described left-hand door fan, is positioned by lock assembly between doorframe and right door leaf between described doorframe and left-hand door fan in connecting keying respectively mutually with right door leaf；
Described lock assembly includes that screw mandrel and diagonal control arm, described screw mandrel are rotated by worm reducer, is cased with nut outside described screw mandrel, and the two ends of described nut are connected with diagonal control arm respectively, and the outer end of described diagonal control arm is connected with lock head component；
Described lock head component includes longitudinal rod and lower longitudinal rod, it is connected by pivoted arm between described upper longitudinal rod with lower longitudinal rod, respectively by tapered end phase activity orientation between described upper longitudinal rod with the upper end of doorframe, between the lower end of lower longitudinal rod and doorframe, described pivoted arm is fixedly connected with diagonal control arm.
As preferably, described worm reducer is regulated by handwheel, and described screw mandrel, upper longitudinal rod, lower longitudinal rod are vertical equity distribution.
Hinge mechanism is conventional structure.
This mechanism has simple in construction, the feature such as easy to operate, laborsaving, flexible.The bearing capacity of tapered end is more than bounce pressure, makes airtight blast door anti-reflective resilience energy power strengthen.3, enabling order: rotate handwheel, drive worm gear case input, output shaft, the screw mandrel being assemblied on output shaft and nut to form screw pair, screw mandrel rotates and makes nut move along a straight line up and down, nut ears assembling diagonal control arm couples pivoted arm and makees rotating angle movement, meanwhile, the tapered end of longitudinal rod up and down being assemblied on pivoted arm is made to shrink slip 70 millimeters.
Therefore, the anti-reflective bullet blocking mechanism of steel structure double-leaf airtight blast door of the present utility model, compact conformation, good airproof performance, easy to operate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
