Description
Technical field
The present invention relates to hermatic door technical field, particularly relate to a kind of medical hermatic door support mechanism.
Background technology
The airtight principle of the smooth automatically-controlled door of various medical airtight class on the market is at present: opening one 45 degree of breach in the track place of closing the door, load-bearing pulley runs to this indentation, there, moves along 45 degree of directions, thus realizing the sinking of door leaf at closing time; Door leaf is pushed to doorframe simultaneously, and door leaf makes air-tight rubber strip compress to the movement of doorframe, thus can complete the air-tightness action of the smooth automatically-controlled door of airtight class. The drawback of this method is in that: on the one hand, and track opening adds the difficulty of the processing of track; On the other hand, track having breach, owing to BOGEY WHEEL stroke in orbit can not stride across breach, therefore often fan door leaf can only use two BOGEY WHEELs, and the quantity of BOGEY WHEEL makes the weight of the door leaf hung be very restricted. Further, bigger problem is: BOGEY WHEEL along 45 degree of breach move downward time, a lateral edges of BOGEY WHEEL is subject to very big extruding, can increase the abrasion of BOGEY WHEEL. The open degree that 45 degree of breach also result in door leaf is restricted, and makes door to fully open. Because there is bigger frictional force between air-tight rubber strip and doorframe, and door leaf open time must lifting fast as far as possible and depart from doorframe, namely door leaf to climb at short notice, this means that motor needs bigger current start, big current start frequently, the life-span of motor can be shortened, will also result in bigger energy loss.
Therefore, prior art existing defects, it is necessary to improve.
Summary of the invention
