[0020] In order to better understand the technical content of the utility model, specific embodiments are cited and described as follows in conjunction with the accompanying drawings. In this disclosure, various aspects of the utility model are described with reference to the accompanying drawings, and many illustrative embodiments are shown in the accompanying drawings. The embodiments of the present disclosure are not necessarily defined to include all aspects of the utility model. It should be understood that the various concepts and embodiments introduced above, as well as those described in more detail below, can be implemented in any of many ways, because the concepts and embodiments disclosed in the utility model are not limited to any implementation method. In addition, some aspects disclosed in the utility model can be used alone, or used in any appropriate combination with other aspects disclosed in the utility model.

[0021] Example 1

[0022] like Figure 1-4 As shown, the first embodiment of the utility model provides an air leakage-proof experimental mouse feed packaging bag, including a packaging bag body 1, a sealing strip 2 is arranged at the front end of the packaging bag body 1, the length of the sealing strip 2 is smaller than the width of the packaging bag body 1, a notch 3 is opened on the left side of the packaging bag body 1, and a fixing mechanism 4 is arranged on the surface of the packaging bag body 1.

[0023] like Figure 1-4 As shown, the packaging bag body 1 is used to package experimental mouse feed. By tearing the notch 3, an opening can be torn out on the front side of the packaging bag body 1, so that the feed inside the packaging bag body 1 can be poured out. By using the sealing strip 2, the opening can be closed to a certain extent after the packaging bag body 1 is torn. Since the length of the notch 3 is smaller than the width of the packaging bag body 1, when the sealing strip 2 itself is completely sealed, a certain gap can still be left at the opening, so that it is convenient to squeeze out the residual air inside the packaging bag body 1. By using the fixing mechanism 4, after the front end of the packaging bag body 1 is rolled up to a certain extent, the rolled-up part can be limited to prevent the rolled-up part from spreading. After the front end part of the packaging bag body 1 is rolled up and limited, the opening will be wrapped inside the rolled-up part, making it difficult for air to enter the inside of the packaging bag body 1 from the opening, thereby preventing the external humid air from entering the inside of the packaging bag body 1.

[0024] Example 2

[0025] Reference Figure 2-4, which is the second embodiment of the utility model, and this embodiment is based on the previous embodiment.

[0026] In this embodiment, the fixing mechanism 4 includes a fixing block 401, which is located on both sides of the packaging bag body 1 and fixedly connected to the packaging bag body 1. The top of the left fixing block 401 is movably connected to a rotating plate 402 through a movable pin, and the right side of the rotating plate 402 is fixedly connected to a limiting rod 403.

[0027] The top of the right fixed block 401 is fixedly connected to the limit frame 404, the right end of the limit rod 403 extends to the inner cavity of the limit frame 404 and is movably connected to the inner cavity of the limit frame 404, the right end of the limit rod 403 and the back of the inner cavity of the limit frame 404 are fixedly connected with magnets 405, and the two magnets 405 have opposite magnetic properties and are magnetically connected.

[0028] The two fixed blocks 401 are fixedly connected to the sides away from each other with auxiliary blocks 406, and a clamping piece 407 is provided at the bottom of the auxiliary block 406. The bottom of the auxiliary block 406 is movably connected to a rotating tube 408 through a bearing, and the inner cavity of the rotating tube 408 is slidably connected to a movable column 409, and the bottom of the movable column 409 extends to the bottom of the rotating tube 408 and is fixedly connected to the top of the clamping piece 407.

[0029] A tension spring 410 is fixedly connected to the top of the movable column 409 , and the top of the tension spring 410 is fixedly connected to the top of the inner cavity of the rotating tube 408 .

[0030] Limiting grooves 5 are provided on both sides of the inner cavity of the rotating tube 408 , and limiting blocks 6 are fixedly connected to both sides of the movable column 409 . One side of the limiting block 6 extends to the inner cavity of the limiting groove 5 and is slidably connected to the inner cavity of the limiting groove 5 .

[0031] like Figure 2-4As shown, the fixing block 401 is used to support and fix the components on the upper and lower sides. The limiting rod 403 can be driven to rotate by rotating the rotating piece 402. After the limiting rod 403 rotates to the inner cavity of the limiting frame 404, the limiting rod 403 can be fixed inside the limiting frame 404 with the cooperation of the two magnets 405. After the position of the limiting rod 403 is fixed, it can limit the front end of the packaging bag body 1 during the rolling process, thereby ensuring that it is rolled into a straight line. After the front end of the packaging bag body 1 is rolled up, the clamping piece 407 is pulled downward and The clamping piece 407 is made to rotate, and when the clamping piece 407 is pulled, the clamping piece 407 will drive the movable column 409 to move. When the movable column 409 moves, it will stretch the tension spring 410 and cause it to deform until the clamping piece 407 rotates to the bottom of the winding part of the packaging bag body 1. After reaching the bottom of the winding part of the packaging bag body 1, the clamping piece 407 is released. At this time, the tension on the tension spring 410 disappears and resets. The reset elastic force of the tension spring 410 can drive the clamping piece 407 to clamp and position the winding part of the packaging bag body 1, thereby preventing the winding part from spreading.

[0032] When in use, the packaging bag body 1 is used to package experimental mouse feed. By tearing the notch 3, an opening can be torn out on the front of the packaging bag body 1, so that the feed inside the packaging bag body 1 can be poured out. By using the sealing strip 2, the opening of the packaging bag body 1 can be closed to a certain extent after the packaging bag body 1 is torn. Since the length of the notch 3 is smaller than the width of the packaging bag body 1, when the sealing strip 2 itself is completely sealed, a certain gap can still be left in the opening, so as to facilitate squeezing out the residual air inside the packaging bag body 1. After squeezing out the air, the rotating piece 402 is rotated, and the rotating piece 402 can drive the limiting rod 403 to rotate. After the limiting rod 403 is rotated to the inner cavity of the limiting frame 404, the limiting rod 403 can be fixed inside the limiting frame 404 with the cooperation of the two magnets 405. After the position of 03 is fixed, it can limit the front end of the packaging bag body 1 during the rolling process, thereby ensuring that it is rolled into a straight line. After the front end of the packaging bag body 1 is rolled up, the clamping piece 407 is pulled downward and rotated. When pulling the clamping piece 407, the clamping piece 407 will drive the movable column 409 to move. When the movable column 409 moves, it will stretch the tension spring 410 and cause it to deform until the clamping piece 407 rotates to the bottom of the rolled part of the packaging bag body 1. After reaching the bottom of the rolled part of the packaging bag body 1, the clamping piece 407 is released. At this time, the tension on the tension spring 410 disappears and resets. The reset elastic force of the tension spring 410 can drive the clamping piece 407 to clamp and position the rolled part of the packaging bag body 1, thereby preventing the rolled part from spreading.
