[0002] Square bottom valve bag is a small bulk packaging container, which is convenient, neat and well sealed. It is one of the most popular packaging materials in the world, especially suitable for export packaging. However, the material of the general bag is relatively soft and smooth. When the bag needs to be opened to put items, it usually needs manual support to place the items in the bag. The bag itself cannot complete independent support, which makes the bag very inconvenient during use, thereby reducing the practicality and convenience of the equipment.

[0003] Based on this, the utility model designs a square bottom valve bag with an upright support structure to solve the above problems. Utility Model Content

[0004] The utility model aims to provide a square bottom valve bag with an upright support structure to solve the problem in the background art that the bag body cannot stand upright independently during use, resulting in the inability of the equipment to complete bagging.

[0027] Among them, the four bottom support mechanisms 2 are located at the four sides of the bottom of the bag body 1, and the four bottom support mechanisms 2 and the four side support mechanisms 3 form a quadrilateral cylinder; this makes the device more convenient when unfolding, and at the same time makes the device form an upright cylinder.

[0028] Among them, the bottom supporting mechanism 2 includes a first fixed rod 5, a rotating shaft 6, a torsion spring 7 and a telescopic arm 8. The first fixed rod 5 is fixedly connected inside the bag body 1. Two rotating shafts 6 are rotatably connected to the first fixed rod 5. A torsion spring 7 is sleeved on the rotating shaft 6. The telescopic arm 8 is installed on the rotating shaft 6. The telescopic arm 8 and the clamping block 4 are movably connected; this is convenient for increasing the bottom supporting force of the bag body 1, making the bag body 1 more stable and convenient when in use, and further improving the practicality and ease of use of the equipment.

[0029] Among them, the locking mechanism 9 includes a shell 10, a rotating rod 11, a gear 12, a first spring 13, a rack 14 and a locking rod 15. The shell 10 is installed in the first fixed rod 5, and the rotating rod 11 is rotatably connected in the shell 10. The gear 12 is installed on the rotating rod 11, and the first spring 13 is fixedly connected in the shell 10. The rack 14 is fixedly connected on the first spring 13. The rack 14 is slidably connected in the shell 10, and the rack 14 and the gear 12 are meshed with each other. One end of the rack 14 is fixedly connected to the locking rod 15, and the locking rod 15 and the telescopic arm 8 are movably connected; it is convenient to operate the storage and deployment of the equipment, so that the equipment can be recycled for multiple times, and at the same time, it can be deployed and stored as needed during use.

[0030] Among them, the splicing mechanism 16 includes a second fixed rod 17, a sliding rod 18, a second spring 19 and a stopper 20. The bag body 1 is fixedly connected with the second fixed rod 17, and a splicing mechanism 16 is rotatably connected to the second fixed rod 17.

[0031] Working principle:

[0032] During operation, when the bag body 1 is folded, the bottom support mechanism 2 and the side support mechanism 3 are both in a retracted state. At this time, the telescopic arm 8 is located inside the first fixed rod 5. At the same time, the telescopic arm 8 and the locking rod 15 are movably connected. At the same time, the multiple splicing mechanisms 16 are folded and blocked by the block 20, so that it forms a shortened state. At this time, the bag body 1 can be folded, and the bottom support mechanism 2 and the side support mechanism 3 will not block it, thereby making the device more convenient to use. When the bag body 1 needs to be supported upright, the rotating rod 11 is rotated to rotate the gear 12. When the gear 12 rotates, the rack 14 moves. At this time, the locking rod 15 and the telescopic arm 8 are disengaged. At the same time, the torsion spring 7 drives the telescopic arm 8 to rotate, thereby opening it. It is engaged with the card block 4. When the four bottom telescopic mechanisms are unfolded, the bottom of the bag body 1 forms a quadrilateral, so that its bottom forms a support, and then the device is more stable when supported. When the bottom support mechanism 2 is unfolded, multiple splicing mechanisms 16 are unfolded in sequence according to the upright height of the bag body 1. When the splicing mechanism 16 is unfolded, the block 20 blocks the second fixing rod 17 in the splicing mechanism 16, so that the two second fixing rods 17 form a connection. The splicing mechanisms 16 unfolded in sequence can make the device more convenient when unfolded. At the same time, the unfolding height of the device can be selected according to needs, which makes the device more convenient to use. The device can be stored and can be upright when in use, further improving the practicality and convenience of use of the device.
