[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0030] Referring to Figure 1 and Figure 2 , an embodiment provided by the present invention: a hand-held paper bag with an anti-opening function, including a bag body 1, a cardboard 3 is fixedly connected to the rear side inside the bag body 1, card slots 4 are opened on the left and right sides of the top of the cardboard 3, a limiting plate 5 is fixedly connected to the front side inside the bag body 1, a limiting groove 6 is opened on the rear side of the limiting plate 5, round grooves 7 are opened on the left and right sides of the top of the limiting plate 5, fixed plates 8 are fixedly connected to both ends of the front side inside the bag body 1, cylinders 9 are slidably connected to the tops of the two fixed plates 8, the bottom ends of the cylinders 9 sequentially penetrate through the limiting groove 6 and the card slots 4, baffles 10 are fixedly connected to the front and rear sides of the two cylinders 9, a first spring 11 is arranged on the outer side of the cylinders 9, limiting holes 12 are opened on the right sides of the bottom ends of the two cylinders 9, a second spring 13 is fixedly connected to one side inside the limiting holes 12, and the right end of the second spring 13 is fixedly connected to a limiter 14. Cross plates 15 are fixedly connected to both ends of the front side of the bag body 1, the rear sides of the two cross plates 15 penetrate through the bag body 1 and are provided with sliding grooves 16, slide blocks 17 are slidably connected to the inside of the two sliding grooves 16, extension blocks 18 are fixedly connected to the left sides of the rear ends of the two slide blocks 17, and a stabilizing mechanism 2 is arranged at the bottom of the bag body 1, and the stabilizing mechanism 2 is used to stabilize the bag body 1;
[0031] Specifically, the pallet 3 needs to be accurately inserted into the limit groove 6 to ensure that the card slot 4 is accurately aligned with the circular groove 7. Then, press the cylinder 9 to pass through the card slot 4 and the circular groove 7 in sequence, so that the baffle 10 will apply pressure to the first spring 11, causing it to deform. At the same time, the second spring 13 will release energy due to the loss of external pressure and push the limiter 14 to pop out, thereby realizing the effective sealing of the bag body 1. When it is necessary to open the bag body 1, the slider 17 should be rotated first to ensure that the extension block 18 faces the limiter 14. By moving the slider 17, the extension block 18 contacts the limiter 14 and applies pressure, causing the limiter 14 and the second spring 13 to retract into the limit hole 12 together. At this time, the first spring 11 will release energy due to the loss of external pressure and push the cylinder 9 to pop out, thereby canceling the limiting state of the pallet 3 and sealing the bag body 1 to prevent accidental opening during transportation, storage, and handling, resulting in the dropping, loss, or damage of the items inside the bag.
[0032] Refer to Figure 1 and Figure 3 , the stabilizing mechanism 2 includes a base 201, the base 201 is slidably connected to the bottom of the bag body 1, four first magnets 202 are fixedly connected to the inner periphery of the base 201, grooves 203 are formed at the four corners of the top of the base 201, fixing bolts 204 are rotatably connected to the top of the plurality of grooves 203, the bottom ends of the plurality of fixing bolts 204 penetrate through the base 201 and are threadedly connected with support feet 205, and second magnets 206 are fixedly connected to the periphery of the inner bottom of the bag body 1;
[0033] Specifically, the base 201 is accurately aligned with the bottom of the bag body 1. At this time, the first magnet 202 and the second magnet 206 are attracted to each other to tightly clamp the bag body 1 to ensure its stability. At the same time, through the rotatably connected fixing bolts 204, the support feet 205 can contact the ground, thereby further stabilizing the overall position of the bag body 1 and preventing the bag body 1 from being easily tilted and falling to the ground when placed on the ground, damaging the internal items.
[0034] Refer to Figure 1 and Figure 2 , cross bars 19 are fixedly connected to the front and rear sides of the bag body 1, handles 20 are slidably connected to the tops of the two cross bars 19, the bottom ends of the two handles 20 penetrate through the cross bars 19, limit bolts 21 are rotatably connected to the left and right sides of the two cross bars 19, the plurality of limit bolts 21 penetrate through the cross bars 19, and a cloth bag 22 is fixedly connected to the front side inside the bag body 1, and an elastic opening 23 is formed at the top of the cloth bag 22;
[0035] Specifically, the cross bars 19 and the handles 20 facilitate the use and handling of the bag body 1. The limit bolts 21 can adjust the length of the handles 20 as needed. The cloth bag 22 facilitates the separation of small items inside the bag and is convenient for taking.
[0036] Refer to Figure 2 andFigure 3 At the bottom of each of the multiple support feet 205, a soft pad 24 is fixedly connected. At equal intervals at the bottom of the multiple soft pads 24, rubber bumps 25 are fixedly connected. At the rear side inside the bag body 1, a clamping plate 3 is fixedly connected. The size of the clamping plate 3 is consistent with the size of the limiting groove 6. At the left end of the front side of the two cross plates 15, fixing blocks 26 are fixedly connected. The rear ends of the two fixing blocks 26 penetrate through the cross plates 15;
[0037] Specifically, the soft pads 24 and the rubber bumps 25 can make the support feet 205 more stable and increase the friction. The consistent sizes of the clamping plate 3 and the limiting groove 6 can better seal the bag body 1. The fixing blocks 26 facilitate the user to move the slider 17 with one hand.
[0038] Working principle: When using the hand-held paper bag with an anti-opening function, first insert the clamping plate 3 into the limiting groove 6 so that the clamping groove 4 is aligned with the circular groove 7. At this time, press the cylinder 9 to sequentially penetrate through the clamping groove 4 and the circular groove 7, so that the baffle 10 presses the first spring 11. At the same time, the second spring 13 loses pressure and ejects the stopper 14 to seal the bag body 1. When it needs to be opened, rotate the slider 17 so that the extension block 18 faces the stopper 14. At this time, move the slider 17 and the extension block 18 presses the stopper 14, so that the stopper 14 and the second spring 13 retract into the limiting hole 12. At the same time, the first spring 11 loses pressure and ejects the cylinder 9 to cancel the limitation on the clamping plate 3;
[0039] And when the bag body 1 is unstable on the ground, align the base 201 with the bottom of the bag body 1. At this time, the first magnet 202 and the second magnet 206 adsorb and clamp the bag body 1 to each other. At the same time, the support feet 205 rotatably connected by the fixing bolts 204 contact the ground to stabilize the bag body 1.
[0040] 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 in the protection scope of the present invention.
