DETAILED DESCRIPTION

[0023] The utility model embodiments will be described below with reference to the accompanying drawings. Figures 1-5 The embodiments described are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] As shown in the drawing, an anti-extrusion packaging bag, comprising a bag body 1, the inner wall of the bag body 1 is fixedly connected with first anti-extrusion plate 2 and second anti-extrusion plate 3 which are mutually symmetrical along the central axis of the bag body 1, two anti-extrusion top rods 4 are rotatably connected on both sides of the first anti-extrusion plate 2, the end of the anti-extrusion top rod 4 is formed with a T-shaped column-shaped clamping pile 41, a plurality of clamping blocks 31 corresponding to the anti-extrusion top rods 4 are formed on the second anti-extrusion plate 3, the clamping block 31 is provided with a T-shaped clamping groove 32 matched with the clamping pile 41 in section, the anti-extrusion top rod 4 can be swung to make the clamping pile 41 clamped into the clamping groove 32, so that the anti-extrusion top rod 4 is horizontally located between the first anti-extrusion plate 2 and the second anti-extrusion plate 3.

[0025] Specifically, the first anti-extrusion plate 2 and the second anti-extrusion plate 3 are fixedly connected on the inner wall of the bag body 1: a plurality of T-shaped column-shaped connecting pieces 5 are provided on the bag body 1, the connecting piece 5 is formed with a clamping head 51 at the small end, a plurality of connecting holes 6 matched with the small end of the connecting piece 5 are formed on the first anti-extrusion plate 2 and the second anti-extrusion plate 3, the clamping head 51 passes through the connecting hole 6 and abuts on the first anti-extrusion plate 2 or the second anti-extrusion plate 3, so as to realize the fixed connection of the first anti-extrusion plate 2 and the second anti-extrusion plate 3 with the bag body 1.

[0026] Specifically, the first anti-extrusion plate 2, the second anti-extrusion plate 3 and the anti-extrusion top rod 4 are made of hard plastic.

[0027] In the above structure, when the anti-extrusion effect on the articles placed in the bag body 1 is needed, the anti-extrusion top rod 4 is pushed to swing towards the second anti-extrusion plate 3, the clamping peg 41 is clamped into the clamping groove 32, the free end of the anti-extrusion top rod 4 is fixedly connected to the second anti-extrusion plate 3 through the cooperation of the clamping peg 41 and the clamping groove 32, and the anti-extrusion rods are horizontally fixed between the first anti-extrusion plate 2 and the second anti-extrusion plate 3 to support and fix the first anti-extrusion plate 2 and the second anti-extrusion plate 3. When the bag body 1 is subjected to external force, the fixed frame composed of the first anti-extrusion plate 2, the second anti-extrusion plate 3 and the anti-extrusion top rod 4 protects the articles in the bag body 1 inside it, and plays an anti-extrusion role. When the packaging bag is stored, the clamping peg 41 is pushed out of the clamping groove 32, and the anti-extrusion rod is swung to fit the inner wall of the first anti-extrusion plate 2. At this time, the bag body 1 can be folded into a flat plate, which is convenient for the storage of the packaging bag. It can be seen that through the above structure, the bag body 1 not only has the anti-extrusion effect on the articles in it, but also can be folded and stored, which is convenient for the use of the packaging bag. Moreover, the structure is simple and compact, does not occupy the cavity of the bag body 1, and the articles are easy to put in and take out. The connection of the first anti-extrusion plate 2 and the second anti-extrusion plate 3 to the bag body 1 through the clamping of the connecting piece 5 enables the first anti-extrusion plate 2 and the second anti-extrusion plate 3 to be easily removed from the bag body 1, which is convenient for freely choosing whether to set the first anti-extrusion plate 2 and the second anti-extrusion plate 3 to play the anti-extrusion role according to the use requirement.

[0028] In addition, the first magnet 42 is embedded on the end face of the clamping peg 41, and the second magnet 33 cooperating with the first magnet 42 is embedded on the groove bottom of the clamping groove 32. When the clamping peg 41 is clamped into the clamping groove 32, the first magnet 42 and the second magnet 33 are attracted. Through the attraction of the first magnet 42 and the second magnet 33, the clamping peg 41 is more stably kept in the clamping groove 32 when clamped into the clamping groove 32, thereby enhancing the stability of the frame composed of the first anti-extrusion plate 2, the second anti-extrusion plate 3 and the anti-extrusion rod, and ensuring the anti-extrusion effect on the articles in the bag body 1.

[0029] In addition, the openings of the two upper and lower adjacent clamping grooves 32 on the same side of the bag body 1 are opposite, so that the two anti-extrusion rods on the same side of the first anti-extrusion plate 2 swing in the direction of the opposite ends when they are swung for storage. When the two anti-extrusion rods swing to the opposite ends and fit, the two first magnets 42 on the clamping pegs 41 of the two anti-extrusion rods are attracted, so that the anti-extrusion rods are stably fitted to the inner wall of the first anti-extrusion plate 2 in the storage state, thereby facilitating the storage of the bag body 1.

[0030] In addition, the first anti-extrusion plate 2 is rotatably connected with a bottom plate 7 at the lower end, the second anti-extrusion plate 3 is formed with a supporting edge 34 at the lower end, when the clamping post 41 is clamped into the clamping groove 32, the bottom plate 7 can be rotatably placed on the supporting edge 34, and after the bottom plate 7 is rotatably placed on the supporting edge 34, the article placed in the bag 1 is supported, the overall strength of the packaging bag is strengthened, the carrying performance of the packaging bag is strengthened, and the bottom plate 7 is located between the lower ends of the first anti-extrusion plate 2 and the second anti-extrusion plate 3 to support, further strengthening the stability of the frame formed by the first anti-extrusion plate 2, the second anti-extrusion plate 3 and the anti-extrusion rod, thereby ensuring the anti-extrusion performance, and when the bag 1 is stored, the bottom plate 7 is swung towards the first anti-extrusion plate 2 and is attached to the inner wall of the first anti-extrusion plate 2.

[0031] In addition, the supporting edge 34 is embedded with a plurality of third magnets 35, and the bottom plate 7 is embedded with a plurality of fourth magnets 71 matched with the third magnets 35, when the bottom plate 7 is placed on the supporting edge 34, the third magnets 35 and the fourth magnets 71 are attracted, and through the cooperation of the third magnets 35 and the fourth magnets 71, the stability of the bottom plate 7 between the first anti-extrusion plate 2 and the second anti-extrusion plate 3 is strengthened.

[0032] In addition, the first anti-extrusion plate 2 is embedded with a plurality of fifth magnets 21, when the bottom plate 7 is rotatably attached to the first anti-extrusion plate 2, the fourth magnets 71 and the fifth magnets 21 are attracted, and through the cooperation of the fourth magnets 71 and the third magnets 35, the bottom plate 7 is stably attached to the inner wall of the first anti-extrusion plate 2, thereby facilitating the storage of the bag 1.

[0033] In addition, the first anti-extrusion plate 2 and the second anti-extrusion plate 3 are respectively bonded with a cushion pad layer 8 of foam material on the opposite faces, the cushion pad layer 8 buffers and absorbs the article placed in the bag 1, thereby strengthening the anti-extrusion performance of the packaging bag.

[0034] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
