The utility model relates to the field of drawing storage cylinder discloses a kind of engineering drawing moisture-proof and wrinkle-proof storage cylinder, including cylinder, the lower side inner wall of cylinder is fixedly connected with fixed disc, the inner wall of fixed disc is slidably connected with moving block, the upper side of moving block is fixedly connected with abutting strip, the outer wall of abutting strip is fixedly connected with connecting block, the lower side inner wall of cylinder is rotatably connected with shaft, the outer wall of shaft is fixedly connected with rotating disc.In the utility model, through the thread connection cooperation inner wall sealing ring of cylinder and cylinder cover, the sealing property of storage cylinder can be effectively enhanced, outside humidity is blocked to enter, good moisture-proof protection is realized;Meanwhile, four annular evenly distributed moving blocks drive abutting strip and buffer pad to abut tightly drawing from all around, it is stably fixed in the cylinder central position, avoid storing or carrying process because of shaking and produce wrinkle, double protection engineering drawing storage quality.

This utility model discloses a portable outdoor tent, including a tent body with cover plates connected to both sides of the tent body. When using this utility model, the user can take out the deflated and rolled-up nylon support columns from the support frame storage bag, then open the manual air valve and sealing plug on the air hose, inflate the support nylon support columns with an air pump, and then insert the formed support nylon support columns into the corresponding assembly fabric sleeves on the outer wall of the tent body. Using the connecting action of fixing hooks and fixing rings, the top of the initially assembled support nylon support columns is connected and fixed to the top of the tent body. Furthermore, by using support nylon support columns with a TPU wear-resistant coating to replace the commonly used metal poles, the tent can be deflated and rolled up for storage. It is lighter than traditional external support frame structures, reduces space requirements, and is easy to carry.
