DETAILED DESCRIPTION
[0023] Reference Figures 1 - 5 A toast packaging bag with anti-seal bursting function includes a packaging bag body 1, pressing plates 2 are fixedly arranged on both sides of the packaging bag body 1, and concave-convex bones 3 are fixedly arranged on the pressing plates 2. The pressing plates 2 are connected to each other through a clamp chain 4. The sliding clamp chain 4 closes the concave-convex bones 3, and the packaging bag is in a sealed state.
[0024] Balance blocks 5 are fixedly installed on both sides of the clip chain 4, and screw rods 6 are threadedly installed on the balance blocks 5. One end of the screw rods 6 is fixedly connected to a clamping block 7, and the other end of the screw rods 6 is fixedly connected to a rotating handle. The clamping block 7 is in contact with the pressing plate 2, and the screw rods 6 are driven to rotate by rotating the handle. During the rotation process, the screw 6 drives the clamping block 7 to squeeze the pressing plate 2, thereby clamping and fixing the pressing plate 2, and at the same time increasing the friction between the clamping block 7 and the pressing plate 2 to prevent the clip chain 4 from falling off the concave-convex bone 3.
[0025] A pressing block 14 is movably installed on one side of the pressing plate 2, and a fixing block 15 is fixedly installed on the other side of the pressing plate 2. The pressing block 14 is fixedly connected to an insertion rod 16, and second grooves are provided on both sides of the insertion rod 16. The insertion rod 16 fits tightly with the fixing block 15. The insertion rod 16 passes through the packaging bag body 1 and squeezes the pressing block 14. The pressing block 14 drives the insertion rod 16 to press against the fixing block 15.
[0026] The fixing block 15 is provided with a plurality of first grooves, the bottom of the first groove is fixedly connected to the limiting block 18 by a compression spring 17, and the second groove on the insertion rod 16 moves to align with the first groove. At this time, the limiting block 18 is pressed against the bottom of the second groove by the restoring action of the compression spring 17, thereby limiting and fixing the insertion rod 16.
[0027] Second grooves are provided on both sides of the insertion rod 16, and the limit blocks 18 are movably matched with the second grooves. The compression springs 17 are symmetrically arranged. The fixing of the insertion rod 16 makes the two sides of the packaging bag body 1 completely fit and fix, preventing the packaging bag from bursting after sealing, thereby improving the sealing effect of the toast packaging bag.
[0028] Both sides of the packaging bag body 1 are fixedly provided with convex plates 8, on which buckles are provided, and the buckles are connected to connecting buckles 9, and the connecting buckles 9 are fixedly connected to connecting blocks 10. The connecting buckles 9 and the buckles make the connection of the hand strap 13 movable.
[0029] The connecting block 10 is threadedly connected to the threaded groove block 11. During long-term use, the handle strap 13 will wear out. Rotate the threaded groove block 11 to separate it from the connecting block 10, so that the handle strap 13 can be detached from the packaging bag body 1, facilitating the replacement of the handle strap 13.
[0030] The threaded groove block 11 is circumferentially provided with an "L"-shaped groove, and the "L"-shaped groove is clamped with an extension strap 12. The "L"-shaped groove enables the threaded groove block 11 to rotate freely without twisting the handle strap 13.
[0031] The extension strap 12 is fixedly connected to the handle strap 13, and an anti-slip pad is fixedly arranged at the topmost end of the handle strap 13. The anti-slip pad facilitates the user's grip and improves the comfort of use.
[0032] A plurality of rivets 19 are inserted into one side of the packaging bag body 1. The rivets 19 are coaxially installed with fixing rings, and the fixing rings are located on the other side of the packaging bag body 1. Rotate the rivets 19 to penetrate the packaging bag body 1. By sleeving the fixing rings on the rivets 19 and rotating the fixing rings, the rivets 19 are fixed, further preventing the packaging bag seal from bursting.
[0033] The packaging bag body 1 includes an outer skin, an elastic layer, and an inner skin. By arranging the elastic layer between the outer skin and the inner skin, the elastic layer strengthens the toughness of the packaging bag and improves the bearing capacity of the packaging bag.
[0034] The working principle of the present utility model is as follows: The sliding zipper 4 closes the concave and convex bones 3. Rotate the screw 6 to press the clamping block 7 against the pressing plate 2, thereby preventing the zipper 4 from falling off. Squeeze the pressing block 14, the inserting rod 16 abuts against the fixing block 15, and the limiting block 18 is engaged with the inserting rod 16 under the action of the compression spring 17, preventing the packaging bag seal from bursting and improving the sealing effect of the packaging bag.
[0035] The above is only a preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent replacements or changes, should be covered by the protection scope of the present utility model.
