DETAILED DESCRIPTION

[0023] The present application is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technical personnel in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0024] like Figure 1 As shown, a wear-resistant foldable packaging bag includes a main body 1, folding lines 3 are arranged on both sides of the main body 1, and also includes two groups of folding components 2. The folding component 2 is arranged on the front side of the main body 1 near the bottom. The folding component 2 includes a splint 201 and an exhaust plate 202. The exhaust plate 202 is arranged on the side of the splint 201 away from the bottom of the main body 1 and is movably connected to the splint 201. The lengths of the splint 201 and the exhaust plate 202 are both longer than the length of the main body 1. Buckle components are arranged at the positions where the splint 201 and the exhaust plate 202 protrude from the main body 1. The buckle components are respectively used to clamp the two groups of splints 201 and the two groups of exhaust plates 202.

[0025] In the above technical scheme, the main body 1 may include two side surfaces, two front surfaces and a bottom surface. When the packaging bag needs to be folded and sorted, the main body 1 only needs to be folded along the folding line 3 to bring the two groups of clamping plates 201 closer to each other, and then the two groups of clamping plates 201 are clamped together by the buckle assembly, and the two groups of exhaust plates 202 are also clamped together, and then the exhaust plate 202 is pushed to move it along the main body 1 in the direction away from the clamping plate 201. During the movement, the exhaust plate 202 squeezes and discharges the air in the main body 1. In this scheme, the degree of exhaust of the air in the main body 1 depends on the distance between the two groups of exhaust plates 202 after the two groups of exhaust plates 202 are clamped together. The smaller the distance, the more obvious the effect of air exhaust. The main body 1 may be rolled and folded around the clamping plate 201 after the exhaust plate 202 moves to the very end, that is, the top position of the main body 1, or the exhaust plate 202 may be pushed while rolling and folding until the folding work is completed.

[0026] Through the cooperation of the exhaust plate 202, the air in the main body 1 can be exhausted as much as possible, so that when folded, it will not expand due to the existence of air inside, affecting the folding effect and occupying the storage space.

[0027] In a specific implementation manner, Figure 2-Figure 4 As shown, the side of the clamp 201 away from the exhaust plate 202 is connected to the anti-wear plate 203, and the anti-wear plate 203 is rotatably connected to the clamp 201 through a rotating shaft 2031. A torsion spring is sleeved on the rotating shaft 2031, and the torsion spring makes the angle between the clamp 201 and the anti-wear plate 203 be (90°, 180°).

[0028] Under normal circumstances, the two groups of splints 201 are in a state of being away from each other, and items such as rice or grains can be placed in the main body 1. At this time, the angle between the splint 201 and the anti-wear plate 203 is the minimum angle. During the dragging process of the main body, the anti-wear plate 201 and the splint 203 can provide good protection for the bottom of the main body 1 and the position near the bottom, thereby preventing the wear of the main body 1 caused by dragging, and extending the service life of the packaging bag. When the packaging bag needs to be folded, it is only necessary to fold the main body 1 along the folding line 3 so that the two groups of splints 201 gradually approach each other. During the process of the two groups of splints 201 gradually approaching each other, the two groups of anti-wear plates 203 also gradually approach each other. Finally, by applying a certain pressure, the two groups of splints 201 are moved to the minimum distance. At this time, the angle between the anti-wear plate 203 and the splint 201 is at the maximum state. Then, the two groups of splints 201 are snapped together through the buckle assembly, and then the subsequent winding and folding operations can be performed.

[0029] In a specific embodiment, the buckle assembly includes a limiting column 205 arranged on a group of clamping plates 201 and an exhaust plate 202, and a rubber block 206 is arranged on the limiting column 205. A first through hole 204 is correspondingly opened on another group of clamping plates 201 and the exhaust plate 202, and the diameter of the first through hole 204 is larger than the diameter of the limiting column 205 and smaller than the diameter of the rubber block 206.

[0030] In actual use, since the rubber block 206 has a certain elasticity, under the action of external force, the rubber block 206 can pass through the first through hole 204 and then respectively clamp the two groups of clamping plates 201 and the two groups of exhaust plates 202 together.

[0031] In a specific implementation manner, Figure 5 As shown, a plastic buckle 2024 is provided on the side of the exhaust plate 202 close to the clamping plate 201 , a wedge block 2029 is provided on the end of the plastic buckle 2024 away from the exhaust plate 202 , and the wedge block 2029 is provided on an inclined surface away from the exhaust plate 202 .

[0032] A first cavity 2015 is formed in a group of clamping plates 201. A first opening 2016 is formed in the first cavity 2015 near the exhaust plate 202. A stopper 2017 is provided in the first cavity 2015. A second through hole 2014 is formed in the first cavity 2015 near the body 1. The second through hole 2014 is formed below the stopper 2017. The stopper 2017 is used to clamp the wedge 2029.

[0033] A push rod 2013 is disposed on the other set of clamping plates 201 at a position corresponding to the second through hole 2014 .

[0034] Under normal circumstances, the plastic buckle 2024 passes through the first opening 2016 and enters the first cavity 2015. The block 2017 can prevent the plastic buckle 2024 from retreating, so that the exhaust plate 202 is fixed on the clamping plate 201. When the packaging bag needs to be folded, the two groups of clamping plates 201 are close to each other, and the push rod 2013 passes through the second through hole 2014 to squeeze the wedge block 2029, so that the plastic buckle 2024 is elastically deformed until the wedge block 2029 can smoothly pass through the block 2017 and exit the first cavity 2015. At this time, the exhaust plate 202 is separated from the clamping plate 201, and then the exhaust plate 202 is moved to discharge the air in the main body 1, and then the subsequent folding operation can be performed.

[0035] In a specific implementation manner, Figure 2 , Figure 3 , Figure 6 As shown, a fixing member is also included, and the fixing member includes a ring 2021 arranged at the end of the exhaust plate 202 and a protrusion 2011 arranged at the end of the clamping plate 201.

[0036] In actual use, the protrusion 2011 can be set vertically with the splint 201. It should be noted that if the protrusion 2011 is set vertically, it should be set in the direction away from the other set of splints 201. When the main body 1 is folded to the end, the ring 2021 is directly sleeved on the protrusion 2011, which can prevent the main body 1 from falling back and loosening. The protrusion 2011 can also be set in the same plane as the splint 201. It should be noted that if it is set in the same plane, the ring 2021 should be rotatably connected with the exhaust plate 202, that is, the ring 2021 should at least be able to rotate to be sleeved on the protrusion 2011.

[0037] In a specific embodiment, the protrusion 2011 is arranged on the same plane as the splint 201, a second cavity 2025 is opened in the exhaust plate 202, a second opening 2028 is opened on the second cavity 2025, a pull rope 2027 passes through the second opening 2028 and is connected to the limit plate 2026 in the second cavity 2025, the other end of the pull rope 2027 is connected to the ring 2021, and a spring 2022 is also arranged in the second cavity 2025, and the spring 2022 is sleeved on the pull rope 2027.

[0038] In actual use, when the main body 1 is folded to the end, the ring 2021 is pulled, and the spring 2022 is compressed. After the ring 2021 is put on the protrusion 2011, the ring 2021 is released, and the spring 2022 is reset to tighten the pull rope 2027, so that the ring 2021 is more firmly connected to the protrusion 2011, to prevent the ring 2021 and the protrusion 2011 from being loose, making the main body 1 loose and affecting the folding effect.

[0039] In a specific implementation, a placement cavity 5 is provided on the clamping plate 201 , and the protrusion 2011 is rotatably connected to the clamping plate 201 via a rotation shaft 4 , and the rotation shaft 4 is disposed in the placement cavity 5 .

[0040] When the packaging bag is needed to store items, the protrusion 2011 can be rotated around the rotating shaft 4 into the placement cavity 5 to store the protrusion 2011 to prevent the protrusion 2011 from affecting the storage process of the items.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
