The technical scheme of the utility model as follows: the transverse pneumatic rolling door comprises two positioning seats fixedly arranged at two shoulders of a door opening respectively, a positioning plate arranged in the middle of the two positioning seats, two cylinders oppositely arranged between the positioning seats and the positioning plate respectively, a guide rod, two ends of which are fixed on the positioning seats and penetrate through the positioning plate, two sliding blocks respectively fixed with the top ends of telescopic rods of the cylinders, a compressor matched with the cylinders, and two rolling curtains respectively hung on the guide rods between the positioning seats and the positioning plate; the rear cover ends of the two cylinders are respectively fixed on the positioning seat, the front cover ends are respectively fixed on two sides of the positioning plate, and the piston rods of the cylinders penetrate through the positioning plate and are fixedly connected with the sliding blocks; the sliding block is sleeved on the guide rod, the roller shutter is arranged between the sliding block and the positioning seat, one side of the roller shutter is fixedly hung on the positioning seat, and the other side of the roller shutter is fixedly hung on the sliding block; thereby the flexible sliding block horizontal slip through cylinder piston rod drives the roll up curtain that opens and shuts.

By arranging the two air cylinders, the air cylinders can be arranged right above the door and do not need to be arranged in a wall body; the two cylinders are oppositely arranged, one of the cylinders drives one roller shutter to open and close, the two cylinders are simultaneously controlled by the compressor, the whole gate can be opened and closed, and the structure is simple and practical; lubricating oil can be coated on the guide rod during use so as to facilitate the opening and closing of the roller shutter, and no spark is generated due to discharge; the structure of setting in the roll of curtain top can be rationally optimized according to particular case, and through this roll of curtain structure, the superstructure of this rolling slats door is small and exquisite, the installation of being convenient for, and the cost is lower.

Further, the guide bars are two, and the sliding block sleeve is established on two guide bars. Through setting up two guide bars, make whole rolling slats door more stable under the state of opening and shutting.

Furthermore, the sliding block is L-shaped, one end arm is sleeved on the guide rod, and the other end arm is fixedly connected with the cylinder telescopic rod; two cylinders are respectively and fixedly arranged at the notch of the L-shaped sliding block. Be the L type through setting up the sliding block, set up the cylinder in L type sliding block breach department, make the roll up curtain structural configuration of rolling up the door more reasonable, the structure is exquisite.

Further, the curtain folds of the roller shutter are vertically arranged. When the roller shutter is made of metal, the vertical shutter is arranged, so that the roller shutter is convenient to open and close.

Further, the roller shutter is suspended by a hanging ring. A guide rail can also be arranged on the guide rod, and a plurality of sliding blocks are arranged on the guide rail and connected with the roller shutter; the sliding block can also be connected with the guide rod in a rolling way to prevent the friction from generating sparks and the like.

When the transverse pneumatic rolling door is in a closed state, the compressor controls the two cylinders to withdraw the telescopic rods, the telescopic rods drive the sliding blocks to slide on the guide rods until the positioning plates, and the sliding blocks drive the rolling doors to the positioning plates, so that the rolling doors are pulled open, and the doors are closed; when the rolling slats door was opened, stretched out the telescopic link through two cylinders of compressor control, the telescopic link drives the sliding block and slides to positioning seat department, and the sliding block drives the roll of curtain and packs up the roll of curtain to positioning seat department to open the gate.

The utility model discloses a horizontal pneumatic rolling slats door compact structure is ingenious, can not produce the spark because of the contact among the electric loop discharges etc. easily rolls up and puts, easily installs, and the cost is with low costs.
