[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Specific embodiments are given below.

[0027] Please refer to Figure 1 - Figure 6The utility model provides a sealing structure of a bag, including a box body 1; the box body 1 is characterized in that: a zipper 7 is provided in the middle of the box body 1; a sealing groove 8 is opened on the outer wall of the box body 1; a sliding frame 3 is slidably provided on the outer wall of the box body 1; a rectangular frame 33 is slidably connected to the inner wall of the sliding frame 3; the sliding frame 3 is provided with two groups; and the two groups of sliding frames 3 are symmetrically arranged with the center line of the rectangular frame 33 as the symmetry axis; the inner wall of the top of the sliding frame 3 contacts the sealing frame 32; the side wall of the sealing frame 32 is fixedly connected to the positioning plate 31; the side wall of the positioning plate 31 is fixedly connected to the push plate 35; the positioning plate 31 contacts the middle of the sliding frame 3; the sealing frame 32 contacts the inner wall of the sealing groove 8; the side wall of the rectangular frame 33 is slidably connected to the slider 5; the side wall of the slider 5 is rotatably connected to the connecting rod 51; the end of the connecting rod 51 rotates The zipper 7 is connected to the side wall of the sliding frame 3; when working, the box body 1 can be sealed by the provided zipper 7. In order to ensure the sealing effect of the zipper 7, after closing the zipper 7, the sliding frame 3 can be pushed to cover the zipper 7. In the process of pushing the sliding frame 3, the sealing frame 32 will be squeezed and deformed until the sealing frame 32 overlaps with the sealing groove 8. At this time, the sealing frame 32 will be reset and stuck on the inner wall of the sealing groove 8. The sealing frame 32 has a certain elasticity. When it contacts the side wall of the box body 1, it will deform, so that the sliding frame 3 can move stably. When the box body 1 is in use, when the expansion layer is opened, the positions of multiple groups of sliding frames 3 on the outer wall of the rectangular frame 33 can be adjusted to ensure that the multiple groups of sliding frames 3 cooperate with the rectangular frame 33. The entire expansion layer and the zipper 7 can be covered, thereby improving the sealing effect of the box body 1.

[0028] Further, such as Figure 1 - Figure 2 and Figure 4 - Figure 5 When the locking cam 31 is unlocked, the locking cam 31 is unlocked and the locking cam 32 is unlocked, so that the locking cam 31 can be unlocked and the locking cam 32 can be unlocked.

[0029] Further, such as Figure 6As shown in the figure, a rectangular groove 36 is provided on the side wall of the rectangular frame 33; a plurality of groups of grooves 37 are provided on the inner wall of the rectangular groove 36; a through groove 38 is provided on the side wall of the sliding frame 3; the specific end of the slider 5 is slidably connected to the inner wall of the rectangular groove 36; the side wall of the slider 5 slides on the inner wall of the through groove 38. During operation, when adjusting the positions of multiple groups of sliding frames 3 on the outer wall of the rectangular frame 33, the slider 5 can be pushed. At this time, the angle of the connecting rod 51 will change, and at the same time, one end of it rotates with the slider 5, and the other end rotates on the side wall of the sliding frame 3. In this way, multiple groups of sliding frames 3 can be unfolded, improving their coverage range and ensuring the sealing effect on the zipper 7. In addition, the plurality of groups of grooves 37 provided ensure that multiple groups of sliding frames 3 can be adjusted according to different ranges of the expansion layer, improving the practicability.

[0030] Further, as Figure 6 shown, a limiting rod 52 is slidably connected through the side wall of the slider 5; a first spring 53 is sleeved on the outer wall of the limiting rod 52; the end of the limiting rod 52 contacts the inner wall of the groove 37; one end of the first spring 53 is fixedly connected to the side wall of the slider 5; the other end of the first spring 53 is fixedly connected to the side wall of the limiting rod 52. During operation, when pulling the limiting rod 52, the limiting rod 52 will stretch the first spring 53 until the limiting rod 52 disengages from the inner wall of the groove 37. At this time, the slider 5 can be pushed to move. When stopping pulling the limiting rod 52, the first spring 53 will pull the limiting rod 52 to reset through its own elasticity, ensuring the stability of its limit.

[0031] Further, as Figure 5 shown, a second spring 63 is sleeved on the outer wall of the fixed rod 61; one end of the second spring 63 is fixedly connected to the side wall of the fixed rod 61; the other end of the second spring 63 is fixedly connected to the side wall of the connecting plate 6. During operation, the second spring 63 has a certain elasticity, and it always pushes the connecting plate 6 through its own elasticity, so that the limiting plate 62 is always inserted into the inner wall of the limiting groove 34, ensuring its limiting effect.

[0032] Further, as Figure 4 shown, the end of the limiting plate 62 is provided with an inclined surface. During operation, the inclined surface provided ensures that when installing the sealing frame 32, the positioning plate 31 will push the limiting plate 62 to move along the inclined surface, eliminating the need for manual pulling and improving the convenience.

[0033] Further, as Figure 1 shown, a password lock 2 is installed on the side wall of the box body 1; a buckle 4 is installed on the side wall of the sliding frame 3; the buckle 4 is clamped inside the password lock 2. During operation, both the password lock 2 and the buckle 4 are prior arts. Through them, the stability and sealing performance of the sliding frame 3 can be ensured. At the same time, the safety of the box body 1 can be ensured. And the staff in this field are all familiar with its principle, so no more introduction will be made here.

[0034] Working principle: The box body 1 can be sealed through the provided zipper 7. To ensure the sealing effect of the zipper 7, after closing the zipper 7, the sliding frame 3 can be pushed to cover the zipper 7. During the process of pushing the sliding frame 3, the sealing frame 32 will be deformed by extrusion until the sealing frame 32 overlaps with the sealing groove 8. At this time, the sealing frame 32 will reset and be stuck on the inner wall of the sealing groove 8. The sealing frame 32 has a certain elasticity. When it contacts the side wall of the box body 1, it will deform, enabling the sliding frame 3 to move stably. When the box body 1 is in use and the expansion layer is opened, the positions of multiple groups of sliding frames 3 on the outer wall of the rectangular frame 33 can be adjusted to ensure the cooperation between multiple groups of sliding frames 3 and the rectangular frame 33, covering the entire expansion layer and the zipper 7, thereby improving the sealing effect of the box body 1.

[0035] When adjusting multiple groups of sliding frames 3, the limiting rod 52 needs to be pulled to disengage it from the inner wall of the groove 37, and then the slider 5 can be pushed. At this time, the angle of the connecting rod 51 will change, and at the same time, one end of it will rotate with the slider 5, and the other end will rotate on the side wall of the sliding frame 3. In this way, multiple groups of sliding frames 3 can be unfolded, increasing their coverage range and ensuring the sealing effect on the zipper 7. In addition, the multiple groups of grooves 37 provided ensure that multiple groups of sliding frames 3 can be adjusted according to different ranges of the expansion layer, improving the practicality.

[0036] When the sealing frame 32 needs to be replaced, the connecting plate 6 can be pulled. The connecting plate 6 will slide on the outer wall of the fixed rod 61, and at the same time, the connecting plate 6 will drive the limiting plate 62 to move until the limiting plate 62 disengages from the inner wall of the limiting groove 34. At this time, the push plate 35 can be pushed, and the push plate 35 will drive the positioning plate 31 and the sealing frame 32 to move simultaneously, so that the sealing frame 32 can be disassembled. It should be noted that the sealing frame 32 has a certain elasticity. When disassembling, it can be stretched at both ends to avoid the rollers and handles provided on the box body 1, improving the practicality.

[0037] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
