Description

Technical Field

[0001] The utility model relates to the technical field of square-bottom valve bags, and specifically relates to a high-strength waterproof square-bottom valve bag. Background Technique

[0002] A square-bottom valve bag is a packaging container, which is convenient, neat and has good sealing performance. It is widely used in packaging powdered or granular solid materials such as edible powder, grain, salt, chemical powder, chemical fertilizer, synthetic materials, explosives, minerals, etc. and flexible materials. Existing square-bottom valve bags not only have good wear resistance but also moisture resistance. However, when the existing bags are moisture-proof, generally a plastic film is added inside the bag body or a waterproof coating is applied on its surface. Such waterproof solutions can carry out moisture-proof of the bag body. However, when this moisture-proof method is used, if it is worn or the film inside the bag body is damaged, the bag body cannot be waterproof, resulting in the equipment being prone to moisture during use and such waterproofing is not stable enough, thus reducing its use effect and practicality.

[0003] Based on this, the utility model designs a high-strength waterproof square-bottom valve bag to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a high-strength waterproof square-bottom valve bag to solve the problems of unstable waterproof effect and easy breakage and moisture of the existing equipment in the above background technique.

A clamping plate is fixedly connected to the inner side of the soft plate. The clamping plate is movably connected in the card slot and the storage groove. A connecting belt is fixedly connected between the two soft plates. A plurality of connecting mechanisms are arranged on the clamping plate. A plurality of self-locking mechanisms are arranged on the clamping plate.

[0007] Preferably, the base is made of soft rubber material. The lower side of the connecting belt is fixedly connected to the protective soft layer. The connecting belt is folded in a Z shape.

[0008] Preferably, the connecting mechanism includes a sliding rod, a first spring, a blocking block and a plugging block. Two sliding rods are slidably connected to the clamping plate. A first spring is sleeved on the sliding rod. A blocking block is installed at one end of the first spring. The blocking block is spherical. A plugging block is fixedly connected in the storage groove. The plugging block is movably connected between the two blocking blocks.

[0009] Preferably, the self-locking mechanism includes a second spring, a lock block and a lock groove. A second spring is fixedly connected to the buckle plate, a lock block is fixedly connected to the second spring, a plurality of lock grooves are formed in the storage groove, and the lock block is movably connected to the lock groove.

[0010] Preferably, the protective soft layer includes a wear-resistant layer, a metal mesh layer, a waterproof layer and a strengthening layer. The protective soft layer is, from outside to inside, a wear-resistant layer, a metal mesh layer, a waterproof layer and a strengthening layer in sequence. The wear-resistant layer, the metal mesh layer, the waterproof layer and the strengthening layer are all adhesively connected, and an oil coating layer is provided on the outside of the wear-resistant layer.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] In the present utility model, the bag body is located on the bottom plate. At this time, the protective soft layer is located in the storage groove, and the plug-in block in the storage groove is movably connected to the two baffle blocks, so that the plug-in block limits the two baffle blocks to ensure the fixation of the buckle plate and the storage groove, and then the protective soft layer can stay in the storage groove continuously. At this time, the bag body can be used to load objects, making it more convenient to load the bag body. After the bag body is loaded, pull the two soft plates to drive the protective soft layer to rise. When the soft plate moves to the card slot position, buckle the buckle plate in the card slot. At this time, the second spring cooperates with the lock block to move in the lock groove, so that the lock block and the lock groove cooperate to keep the buckle plate buckled in the card slot. When the buckle plate is buckled in the card slot, the connecting belt is folded in a Z shape, and at the same time, the bag body is located inside the protective soft layer. At this time, the protective soft layer can effectively protect the bag body, avoiding the situation of water leakage when the waterproof property inside the bag body is reduced. At the same time, the metal mesh layer in the protective soft layer can increase the strength of the bag body and prevent the bag body from being scratched during use, further extending the service life of the equipment. When the equipment is not in use, the protective soft layer can be re-stored in the storage groove, so that the bag body can be loaded again, making the equipment recyclable, and further improving the safety and convenience of the equipment during use.
