DETAILED DESCRIPTION

The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

Example:

As shown in Figures 1 and 2, a three-in-one packaging bag includes a packaging bag body 1, wherein the packaging bag body 1 includes a bag body front 19 and a bag body back 20, and a plurality of strip-shaped first sealing plates 13 are horizontally arranged on the bag body back 20 from bottom to top along its height direction, wherein the first sealing plates 13 are made of plastic, and plug-in rings 11 are arranged at both ends of each first sealing plate 13, and the plug-in rings 11 are made of rubber rings; the bag body front 19 is detachably connected to a second sealing plate 3, and the second sealing plate 3 is also made of plastic, and the first sealing plate 13 and the second sealing plate 3 both have a certain The hardness and toughness of the second sealing plate 3 are fixedly connected with plug-in blocks 5 at both ends. The plug-in blocks 5 are made of rubber material with certain toughness, and the plug-in blocks 5 have protrusions on both sides. The two plug-in blocks 5 are respectively used to be inserted into the plug-in rings 11 on both sides of the packaging bag body 1. When the plug-in block 5 is inserted into the plug-in ring 11, the protrusions on both sides of the plug-in block 11 are squeezed through the plug-in ring 5, and then the protrusions are respectively abutted against the side walls of the plug-in ring 11, thereby fixing the plug-in block 5, and the plug-in block 5 needs to be squeezed hard to make the plug-in block 5 detach from the plug-in ring 11. In this scheme, through four strip-shaped first sealing plates 13, the first sealing plate 13 closest to the topmost particle can be selected to seal the opening of the packaging bag body 1 according to the remaining amount of particles, thereby strengthening the sealing effect;

By setting the second sealing plate 3, the plug-in block 5 and the plug-in ring 11, and by vertically moving the second sealing plate 3, the second sealing plate 3 is made to correspond to the first sealing plate 13 which is closest to the topmost particle at this time, and the plug-in blocks 5 at both ends of the second sealing plate 3 are respectively inserted into the plug-in rings 11 at both ends of the first sealing plate 13, the first sealing plate 13 and the second sealing plate 3 respectively drive the front side 19 of the bag body and the back side 20 of the bag body to fit together, thereby sealing the opening of the packaging bag body 1, prolonging the time for the particles to be exposed to moisture as much as possible and reducing the amount of moisture absorbed by the particles.

As shown in Fig. 1 and Fig. 2, the two ends of the first sealing plate 13 are fixed with fixing plates 10, the fixing plates 10 are made of cloth, a circular hole 18 is provided on the fixing plates 10, and the plug-in ring 11 is glued and fixed at the circular hole 18. By providing the fixing plates 10 and the circular hole 18, the plug-in ring 11 can be installed. Four puncture blocks 12 are fixed to the second sealing plate 3 along its length direction, the puncture blocks 12 are cone-shaped, the bottom surface of the cone is fixed to the second sealing plate 3, the cone body of the cone is made of rubber, and its surface is a rough surface, but a stainless steel tip is glued to the top tip, and each of the first sealing plates 13 is provided with a puncture hole 14, and the inner wall of the puncture hole 14 is a rough surface. By setting the puncture block 12 and the puncture hole 14, the stainless steel tip of the puncture block 12 passes through the front side 19 and the back side 20 of the packaging bag body 1, and then the vertebral body of the puncture block 12 is inserted into the puncture hole 14. Due to the friction between the puncture block 12 and the puncture hole 14, the puncture block 12 is clamped in the puncture hole 14, so that the middle part of the first sealing plate 13 and the second sealing plate 3 is also tightly fitted, further enhancing the sealing effect.

As shown in FIG2 , a Velcro hook surface 17 is fixedly connected to one side of the fixing sheet 10 facing the second sealing plate 3, and the packaging bag body 1 further comprises two bag body side surfaces 15, and the bag body side surfaces 15 are provided with Velcro fleece surfaces 16 for cooperating with the Velcro hook surface 17. By providing the Velcro hook surface 17 and the Velcro fleece surface 16, and bonding the Velcro hook surface 17 to the Velcro fleece surface 16, the fixing sheet 10 can be stored after the packaging bag body 1 is folded and stored.

As shown in FIG3 , the packaging bag body 1 is composed of an outer layer 9, a middle layer 2 and an inner layer 7. The outer layer 9 is made of kraft paper, the middle layer 2 is made of woven cloth, and the inner layer 7 is made of PP material. Kraft paper has a high tensile strength and high moisture resistance and non-deformation ability, which prevents the packaging bag body 1 from deforming and breaking due to water absorption; the setting of woven cloth material can enhance the toughness of the packaging bag body 1 and is not easy to be torn; PP material has a high strength and a low oxygen permeability, and is moisture-proof.

As shown in FIG3 , the middle layer 2 is formed by interweaving braided ropes 4. After the braided ropes 4 are interwoven, glue is applied at the interweaving parts, and the glue is cured to form a reinforcing block. The setting of the reinforcing block 6 further strengthens the tensile strength between the braided ropes 4, and further strengthens the toughness of the packaging bag body 1, which is not easy to be torn. A convex block 8 is provided between the middle layer 2 and the inner layer 7. The convex block 8 is made of foam material. When the items inside the packaging bag body 1 are vibrated, the elastic convex block 8 is provided to buffer and disperse the force, thereby reducing the possibility of damage to the items.

Working principle:

When a certain amount of particles in the packaging bag body 1 have been used and the packaging bag body 1 needs to be sealed, first separate the Velcro hook surface 17 from the Velcro fur surface 16, and then move the second sealing plate 3 to make it correspond to the first sealing plate 13 which is closest to the top particles at this time, and insert the plug-in blocks 5 at both ends of the second sealing plate 3 into the plug-in rings 11 at both ends of the first sealing plate 13 respectively, and press the middle part of the first sealing plate 13 and the second sealing plate 3 to make the puncture block 12 pierce into the puncture hole 14, so that the front side 19 of the packaging bag body 1 and the back side 20 of the packaging bag body 1 are fitted together, and the opening of the packaging bag body 1 is sealed, and the whole operation is completed.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
