[0025] The present invention will be further described in detail below with reference to the accompanying drawings.
[0026] Example:
[0027] Reference Figure 1 - Figure 4 The present invention discloses a reusable packaging bag with a sliding sealing structure, including a sealing bag 1, a sealing component 2 is provided inside the upper opening of the sealing bag 1, and a pleated part 3 is provided at the opening of the sealing bag 1 and below the sealing component 2.
[0028] The sealing assembly 2 includes a fixed slide rail 21, an insertion slide rail 22, and a slider 23. The fixed slide rail 21 is fixedly disposed on the left side of the opening of the sealed bag 1, the insertion slide rail 22 is fixedly disposed on the right side of the opening of the sealed bag 1, and the slider 23 is slidably disposed inside the fixed slide rail 21.
[0029] The fixed slide rail 21 includes a fixed plate 211, which is fixedly connected to the inner wall of the sealed bag. A support plate 212 is provided at the bottom end of the fixed plate 211, and an upper edge plate 213 is provided at the upper end of the side of the support plate 212 away from the fixed plate 211.
[0030] The insertion slide rail 22 includes a second fixing plate 221, which is fixedly connected to the inner wall of the sealed bag and corresponds to the position of the first fixing plate 211. A pressure plate 222 is provided at the upper end of the second fixing plate 221, and a lower insertion plate 223 is provided at the bottom end of the pressure plate 222 on the side away from the second fixing plate 221.
[0031] A fixing component 4 is provided between the upper edge plate 213 and the lower insertion plate 223.
[0032] In this embodiment, as Figure 1 and Figure 2As shown, when closing the sealing bag 1, the side of the sealing bag 1 corresponding to the slide rail 22 is lifted upwards, the middle of the lower insert plate 223 is inserted between the fixing plate 211 and the upper edge plate 213, and both sides of the lower insert plate 223 are pushed so that the lower insert plate 223 is inserted between the fixing plate 211 and the upper edge plate 213. Then the slider 23 is pushed to close the fixing assembly 4, fixing the upper edge plate 213 and the lower insert plate 223, thereby improving the sealing performance of the sealing bag 1.
[0033] The first fixing plate 211, the support plate 212, and the upper edge plate 213 form an upward-opening U-shaped structure, while the second fixing plate 221, the pressure plate 222, and the lower insertion plate 223 form a downward-opening U-shaped structure. When the lower insertion plate 223 is inserted between the first fixing plate 211 and the upper edge plate 213, the two U-shaped structures interlock. Figure 2 As shown, when there are many items inside the sealed bag 1, only the two U-shaped structures can be tightly fitted, which can effectively prevent the sealed bag 1 from bursting open.
[0034] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 3 As shown, the fixing component 4 includes a locking groove 41 and a locking rod 42. The locking rod 42 is fixedly disposed on the side wall of the lower insert plate 223 and faces the fixing plate 221. The locking groove 41 is opened on the side wall of the upper edge plate 213 and faces the fixing plate 211.
[0035] In this embodiment, after the lower insert plate 223 is inserted between the fixing plate 211 and the upper edge plate 213, the position of the locking rod 42 corresponds to the locking groove 41. At this time, the slider 23 is pushed, and the lower insert plate 223 is pushed by the slider 23, so that the locking rod 42 provided on the side wall of the lower insert plate 223 is embedded in the interior of the locking groove 41. Since the cross-sections of both the locking rod 42 and the locking groove 41 are larger than a semicircle, when the locking rod 42 and the locking groove 41 are engaged, the side wall of the locking groove 41 can lock the locking rod 42. Figure 2 As shown, this achieves the purpose of fixing the lower insert plate 223 and the upper edge plate 213, and can improve the sealing performance of the equipment.
[0036] In a further preferred embodiment of this utility model, such as Figure 1 As shown, the pleated portion 3 has a mesh structure.
[0037] In this embodiment, the mesh-like pleats 3, when there are many items inside the sealed bag 1, and pressure is applied to the bag opening, the expansion of the pleats 3 can reduce the impact of the items on the bag opening, thus protecting the sealed bag 1 from damage.
[0038] In a further preferred embodiment of this utility model, such as Figure 2 and Figure 4 As shown, the slider 23 includes a bottom slide plate 231, which is slidably disposed at the top of the support plate 212. A triangular platform 232 is provided on the right side of the top of the bottom slide plate 231, and a pressing platform 233 is provided on the left side of the top of the bottom slide plate 231.
[0039] In this embodiment, as Figure 2 As shown, the end of the lower insert plate 223 is provided with a groove that cooperates with the triangular truss 232. When the sealed bag 1 is closed, the triangular truss 232 is located inside the groove. At this time, the triangular truss 232 only contacts the lower insert plate 223 and cannot provide support for the lower insert plate 223. When the sealed bag 1 is opened, the pressing platform 233 is pushed first, so that the bottom slider 23 slides at the top of the support plate 212. At this time, the triangular truss 232 moves along with it and provides support for the position where the lower insert plate 223 and the upper edge plate 213 are in contact. This pushes the locking rod 42 provided on the side wall of the lower insert plate 223 out of the locking groove 41. When the slider 23 moves to the other end, the locking rod 42 completely disengages from the locking groove 41. The lower insert plate 223 is moved upward by manually pulling the pull ring 5 and disengages from the fixed plate 211 and the upper edge plate 213, thereby achieving the purpose of opening the sealed bag 1.
[0040] On the other hand, when sealing the bag 1, first pull the ring 5 and push the lower insert plate 223 to the position corresponding to the upper edge plate 213 and the fixing plate 211. Then insert the lower insert plate 223 between the two and push the slider 23 again. At this time, the pressing table 233 will lock the locking rod 42 provided on the side wall of the lower insert plate 223 into the inside of the locking groove 41, so as to fix the lower insert plate 223 and the upper edge plate 213. When the bag 1 is completely sealed, the triangular table 232 is again located inside the groove.
[0041] In a further preferred embodiment of this utility model, such as Figure 2 , Figure 3 and Figure 4 As shown, the side wall of the fixing plate 211 is provided with a plurality of guide strips 214, and the side wall of the pressing table 233 is provided with a plurality of guide grooves 234, which slide in cooperation with the guide strips 214.
[0042] In this embodiment, by setting the guide groove 234 and the guide bar 214, when pushing the pressing table 233 to slide, the pressing table 233 is always vertically upward, which improves the stability of the pressing table 233 when sliding.
[0043] In a further preferred embodiment of this utility model, such as Figure 1 As shown, a pull ring 5 is fixedly provided at the position corresponding to the opening of the sealed bag 1 and the fixing plate 221.
[0044] In this embodiment, the pull ring 5 is used to control the lower insert plate 223 to arch upward, so that the lower insert plate 223 can be inserted into the gap between the fixing plate 211 and the upper edge plate 213, and it is also convenient to pull the lower insert plate 223 out from it.
[0045] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
