[0002] Packaging bags are widely used in daily life and various industries, including food, medicine, daily necessities, electronic products, etc. They are not only used for packaging and protecting products, but also play an important role in the processes of transportation, storage and sales.

[0003] When traditional packaging bags are used, there may be no protective measures, which may cause babies to accidentally tear them. If the inside of the packaging bag contains solids and the baby eats them by mistake, it will cause harm to the body.

[0004] In view of this, in order to research and improve the existing problems, a packaging bag with an anti-mistearing function is provided. The structure is reasonably designed, has high stability, and takes into account various aspects of application. It aims to solve problems and improve the practical value through this technology. Content of the Utility Model

[0005] The utility model connects a first fixing strip and a second fixing strip through a tearing strip. When the tearing strip is not opened, the first fixing strip and the second fixing strip cannot open a large gap, so the bag mouth cannot be opened, realizing a packaging bag with an anti-mistearing function.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme: a packaging bag with an anti-mistearing function, including a bag body. A first fixing strip for fixing is arranged on one side of the bag body. A second fixing strip matching the first fixing strip is arranged on the opposite side of the first fixing strip. A fixing groove is opened on the side of the second fixing strip away from the first fixing strip. A fixing buckle matching the fixing groove is movably connected inside the fixing groove. An anti-slip strip is arranged on the side of the fixing buckle close to the outside. A tearing strip for pre-tightening is arranged around the first fixing strip. A connecting hole is opened on the side of the first fixing strip close to the second fixing strip. A fixing rod is fixedly connected inside the connecting hole. A first fixing block is arranged at one end of the fixing rod away from the connection part. A second fixing block is arranged at the lower end of the first fixing block. A spring for resetting is fixedly connected to the lower end of the second fixing block. A connecting sleeve for connecting and fixing the connecting hole is arranged on the side of the second fixing strip close to the first fixing strip. A buckle is movably connected to one end of the connecting sleeve close to the first fixing strip. A spring rod is fixedly connected to the rear end of the buckle. A connecting plate is fixedly connected to the end of the connecting sleeve away from the first fixing strip. A push rod is fixedly connected to the connecting plate on the opposite side of the connecting sleeve.

[0007] Preferably, the upper end of the bag body is heat-sealed during factory production. The first fixing strip and the second fixing strip are fixedly connected to both sides of the bag body, which are higher than the bag body, and the first fixing strip and the second fixing strip are parallel in the same plane.

[0008] Preferably, two sets of guiding grooves are provided at the upper and lower ends of the fixing groove. The upper and lower ends of the fixing buckle are fixedly connected with sliders matching the guiding grooves inside the fixing groove. A number of anti-slip strips are fixedly connected to the side of the fixing buckle close to the outside.

[0009] Preferably, the tearing strip is movably connected to the first fixing strip. One end of the tearing strip is fixedly connected to the fixing buckle, and the other end of the tearing strip far from the fixing buckle is movably connected to the inside of the first fixing strip.

[0010] Preferably, a number of connecting holes are provided on the side of the first fixing strip close to the second fixing strip. The fixing rod is fixedly connected to the inner bottom end and is fixedly connected to the first fixing strip. The first fixing block is fixedly connected to the upper end of the fixing rod. The second fixing block is movably connected to the lower end of the first fixing block. One end of the spring is fixedly connected to the lower end of the second fixing block, and the other end is fixedly connected to the fixing rod.

[0011] Preferably, the outer diameter of the connecting sleeve is matched with the inner diameter of the connecting hole. Two sets of buckles are movably connected inside the connecting sleeve. An empty groove is provided at the connection part of the buckles inside the connecting sleeve. The front end of the empty groove matches the buckle. The side of the buckle facing the connecting hole is a cut surface. The buckle is connected to the empty groove inside the connecting sleeve through a spring rod.

[0012] Preferably, the number of connecting sleeves are connected through a connecting plate. The connecting plate is movably connected inside the second fixing strip. One end of the center is fixedly connected with a push rod. The push rod penetrates through the second fixing strip and is connected to the outside. A spring is fixedly connected to the outside of the push rod. One end of the spring is fixedly connected to the connecting plate, and the other end is fixedly connected to the second fixing strip.

[0013] The utility model has the following beneficial effects: After the bag mouth is opened and needs to be closed again, insert the connecting sleeve into the connecting hole. Since the distance between the two sets of buckles is smaller than the maximum size of the first fixing block, and the side of the buckle close to the first fixing block is a cut surface. When the connecting sleeve enters, because the surface of the first fixing block is an arc surface from small to large, when the cut surface of the buckle touches the front end of the first fixing block, due to the arc surface of the first fixing block, the buckle will contract. When the buckle moves to the rear end of the first fixing block, the buckle will extend inward due to the spring rod. After the buckle extends out, since the distance between the two sets of buckles is smaller than the size of the first fixing block, and the other side of the buckle is not a cut surface, so the buckle cannot be pulled out when passing through the first fixing block. And when the buckle passes through the first fixing block, the first fixing strip and the second fixing strip are already in contact with each other, thus fixing the bag mouth again after it is opened.

[0027] Referring to Figures 1-9 , an embodiment provided by the present utility model: a packaging bag with an anti-mis-tearing function, including a bag body 1. On one side of the bag body 1, there is a first fixing strip 2 for fixing. On the opposite side of the first fixing strip 2, there is a second fixing strip 3 matching the first fixing strip 2. On the side of the second fixing strip 3 away from the first fixing strip 2, there is a fixing groove 4. Inside the fixing groove 4, there is a fixing buckle 5 movably connected to the fixing groove 4. On the side of the fixing buckle 5 close to the outside, there is an anti-slip strip 6. Around the first fixing strip 2, there is a tearing strip 7 for pre-tightening. On the side of the first fixing strip 2 close to the second fixing strip 3, there is a connection hole 8. Inside the connection hole 8, there is a fixing rod 9 fixedly connected. At the end of the fixing rod 9 away from the connection, there is a first fixing block 10. At the lower end of the first fixing block 10, there is a second fixing block 11. At the lower end of the second fixing block 11, there is a spring 12 for resetting fixedly connected. On the side of the second fixing strip 3 close to the first fixing strip 2, there is a connection sleeve 13 for connecting and fixing the connection hole 8. Inside the connection sleeve 13, at the end close to the first fixing strip 2, there is a buckle 14 movably connected. At the rear end of the buckle 14, there is a spring rod 15 fixedly connected. At the end of the connection sleeve 13 away from the first fixing strip 2, there is a connecting plate 16 fixedly connected. On the opposite side of the connection sleeve 13, the connecting plate 16 is fixedly connected with a push rod 17.

[0028] In an optional embodiment: When the bag body 1 leaves the factory, the upper end is heat-sealed to better preserve the items inside. The first fixing strip 2 and the second fixing strip 3 are fixedly connected to both sides of the bag body 1, which is higher than the bag body 1, and the first fixing strip 2 and the second fixing strip 3 are parallel in the same plane, so that it can be better sealed and preserved after the bag mouth is opened.

[0029] In an alternative embodiment: Two sets of guiding grooves are provided at the upper and lower ends of the fixing groove 4, and sliding blocks matching the guiding grooves inside the fixing groove 4 are fixedly connected to the upper and lower ends of the fixing buckle 5, making the fixing more stable and preventing the fixing buckle 5 from falling off when subjected to small friction. A number of anti-slip strips 6 are fixedly connected to the side of the fixing buckle 5 close to the outside, playing an anti-slip role when it is opened, thereby making it more convenient to open.

[0030] In an alternative embodiment: The tearing strip 7 is movably connected to the first fixing strip 2. One end of the tearing strip 7 is fixedly connected to the fixing buckle 5, and the other end of the tearing strip 7 away from the fixing buckle 5 is movably connected to the inner side of the first fixing strip 2. Since the tearing strip 7 connects the first fixing strip 2 and the second fixing strip 3, when the tearing strip 7 is not opened, the first fixing strip 2 and the second fixing strip 3 cannot be opened too wide, so the bag opening cannot be opened.

[0031] In an alternative embodiment: A number of connecting holes 8 are provided on the side of the first fixing strip 2 close to the second fixing strip 3. The fixing rod 9 is fixedly connected to the inner bottom end and is fixedly connected to the first fixing strip 2. The first fixing block 10 is fixedly connected to the upper end of the fixing rod 9. The second fixing block 11 is movably connected to the lower end of the first fixing block 10. One end of the spring 12 is fixedly connected to the lower end of the second fixing block 11, and the other end is fixedly connected to the fixing rod 9. When the second fixing block 11 is pulled up, it will be reset by the spring 12, thereby preventing the second fixing block 11 from being connected to the first fixing block 10 and causing inability to fix.

[0032] In an alternative embodiment: The outer diameter of the connecting sleeve 13 matches the inner diameter of the connecting hole 8. There are two groups of buckles 14 movably connected inside the connecting sleeve 13. An empty groove is provided at the connection of the buckles 14 inside the connecting sleeve 13. The front end of the empty groove matches the buckles 14. The side of the buckles 14 facing the connecting hole 8 is a cut surface. The buckles 14 are connected to the empty groove inside the connecting sleeve 13 through spring rods 15. After the bag opening is opened, when the bag opening needs to be closed again, the connecting sleeve 13 is aligned with the connecting hole 8 and inserted. Since the distance between the two groups of buckles 14 is smaller than the maximum dimension of the first fixing block 10, and the side of the buckles 14 close to the first fixing block 10 is a cut surface. When the connecting sleeve 13 enters, because the surface of the first fixing block 10 is an arc surface that gradually increases from small to large, when the cut surface of the buckles 14 touches the front end of the first fixing block 10, due to the arc surface of the first fixing block 10, the buckles 14 will contract. When the buckles 14 move to the rear end of the first fixing block 10, the buckles 14 will extend inward due to the spring rods 15. After the buckles 14 extend, since the distance between the two groups of buckles 14 is smaller than the size of the first fixing block 10 and the other side of the buckles 14 is not a cut surface, the buckles 14 cannot be withdrawn when passing through the first fixing block 10. And when the buckles 14 pass through the first fixing block 10, the first fixing strip 2 and the second fixing strip 3 are already in contact with each other, so the buckles 14 cannot continue to enter. When released, because the buckles 14 are movably connected to the inside of the second fixing strip 3 through the connecting plate 16, by pushing the push rod 17, the connecting plate 16 is pushed forward, thus pushing the buckles 14 to continue to enter the inside of the connecting hole 8. When the cut surface of the buckles 14 touches the second fixing block 11, they will contract to both sides and thus enter the lower end along the second fixing block 11. Since the connecting plate 16 is connected to the inside of the second fixing strip 3 through a spring 12, after releasing the push rod 17, it will rebound by the force of the spring 12. When the connecting plate 16 rebounds, it will drive the buckles 14 to rebound, so the buckles 14 drive the second fixing block 11 to rise synchronously. When the second fixing block 11 rises to contact the first fixing block 10, the second fixing block 11 cannot move. At this time, the buckles 14 will move outward through the cut surface of the second fixing block 11, so that the buckles 14 will fall on the outer surface of the first fixing block 10 when detaching from the second fixing block 11 and then slide out. After the buckles 14 detach from the second fixing block 11, the second fixing block 11 will be reset by the force of the spring 12.

[0033] In an alternative embodiment: Several groups of connecting sleeves 13 are connected through a connecting plate 16. The connecting plate 16 is movably connected to the inside of the second fixing strip 3. A push rod 17 is fixedly connected to the center of one end. The push rod 17 passes through the second fixing strip 3 and is connected to the outside. A spring 12 is fixedly connected to the outside of the push rod 17. One end of the spring 12 is fixedly connected to the connecting plate 16 and the other end is fixedly connected to the second fixing strip 3. When the user presses the push rod 17, it will push the connecting plate 16 forward. When released, the connecting plate 16 will automatically reset due to the spring 12, so that the user does not need to manually reset, thus improving the convenience during use.

[0034] Working principle and process: When the user opens it, they need to first take out the fixing buckle 5 from inside the fixing groove 4, and then tear the tearing strip 7 through the fixing buckle 5. After tearing, press the push rod 17 to separate the first fixing strip 2 from the second fixing strip 3, so as to open the bag mouth seal. When it needs to be closed after opening, align the connecting sleeve 13 with the connecting hole 8 and insert it, so that the buckle 14 is fixed through the first fixing block 10. When it needs to be opened, press the push rod 17 to push the connecting plate 16, and the connecting plate 16 pushes the buckle 14 to separate the first fixing strip 2 from the second fixing strip 3, thereby opening it.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
