[0042] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.
[0043] Example 1
[0044] like Figures 1 to 4 As shown, this embodiment 1 discloses a vacuum compression bag with a frame, including a flexible bag body 2 and a frame 1. The top of the flexible bag body 2 has a bag opening for placing items. The frame 1 is rectangular and is located in the bag opening area of the flexible bag body 2. The frame 1 is made of existing rigid plastic. The circumferential inner wall of the frame 1 is connected and fixed to the outer wall of the bag opening of the flexible bag body 2 by existing welding or bonding methods, so that the frame 1 directly forms the boundary outline of the bag opening. The frame 1 is equipped with a cover plate 3. Several buckle plates 4 are pivotally connected to the periphery of the cover plate 3. The periphery of the frame 1 has a buckle edge 41 that fastens to the buckle plates 4. The buckle plates 4 fasten to achieve detachable fixation between the cover plate 3 and the frame 1. A sealing groove (not shown in the figure) extending in the circumferential direction is provided between the frame 1 and the cover plate 3. A sealing ring (not shown in the figure) is provided in the sealing groove. When the cover plate 3 and the frame 1 are fixed, the sealing ring is used to achieve a seal between the cover plate 3 and the frame 1, so that the flexible bag body 2 forms a sealed chamber. The sealing groove can be set on the frame 1 or on the cover plate 3.
[0045] An air nozzle 32 or an air extraction device 31 connected to an air extraction device is provided on the cover plate 3 or the flexible bag body 2. The air extraction device 31 can be an existing air extraction pump.
[0046] A bottom plate 5 is fixed to the outer bottom of the flexible bag 2, away from the bag opening. The bottom plate 5 is parallel to the frame 1 and is used to maintain the bottom of the flexible bag 2 in an unfolded state. The connection structure between the bottom plate 5 and the flexible bag 2 adopts an outer fixing structure. The outer fixing structure is as follows: If the bottom plate 5 is a solid plate, the flexible bag 2 can have an opening at the bottom, and the bottom plate 5 is directly fixed to the periphery of the lower opening of the flexible bag 2 by existing welding or bonding methods. An air nozzle 32 or an air extraction device 31 for connection with an air extraction device can be provided at the bottom plate 5. The air extraction device 31 can be an existing air extraction pump. If the bottom plate 5 has weight reduction holes or is a solid plate, and the lower end of the flexible bag 2 does not have a bag opening, the outer wall of the flexible bag 2 is directly fixed to the bottom plate 5 by existing welding or bonding methods or mechanical fastening methods such as easy-pull buckles.
[0047] Example 2
[0048] like Figures 5 to 7 As shown, the difference between Embodiment 2 and Embodiment 1 is that the frame 1 further includes a mating frame 6, which includes a first mating frame 61 and a second mating frame 62. The first mating frame 61 and the second mating frame 62 are fixed to the frame 1 by screws. Vertically extending abutting protrusions 8 are provided at the four corners of the second mating frame 62 and the base plate 5 on opposite sides. When the vacuum compression belt is evacuated, the abutting protrusions 8 of the second mating frame 62 and the base plate 5 can abut against each other.
[0049] The cover plate 3 is provided with a sealing groove 71 that extends in the circumferential direction and opens downward. A sealing ring 7 is provided in the sealing groove 71. The periphery of the second mating frame 62 is provided with a fastening flange 41 that is fastened to the buckle plate 4. When the buckle plate 4 is fastened to the second mating frame 62, the cover plate 3 and the frame 1 are sealed together.
[0050] The first mating frame 61 and the second mating frame 62 can also be integrally formed with the frame 1.
[0051] Example 3
[0052] like Figures 8 to 10 As shown, frame 1 is positioned below the bag opening, and flexible bag body 2 extends above the frame to form a foldable flexible extension section 22. A zipper sealing strip 21 is provided at the upper end of the flexible bag body 2, and the zipper sealing strip 21 is a component used in any existing vacuum bag for sealing via a zipper. When the zipper sealing strip 21 is closed, the entire flexible bag body 2 forms a sealed chamber.
[0053] The connection structure between frame 1 and flexible bag 2 can adopt an inner and outer frame structure, including an inner support part 11 located inside the flexible bag 2 and an outer support part 12 located outside the bag, and the flexible bag is clamped and fixed by the inner and outer support parts.
[0054] likeFigure 9 As shown, the frame 1 includes a rectangular outer support portion 12 and an inner support portion 11. The inner support portion 11 is placed inside the upper part of the flexible bag body 2, and the outer support portion 12 is located outside the upper part of the flexible bag body 2. The inner wall of the outer support portion 12 is provided with several upward-opening and inverted T-shaped grooves. The outer wall of the inner support portion 11 is provided with locking blocks 111 that correspond one-to-one with the T-shaped grooves. When the locking blocks 111 are placed in the T-shaped grooves, they are rotated at a certain angle to fix the outer support portion 12 and the inner support portion 11, thereby clamping the flexible bag body 2 between the outer support portion 12 and the inner support portion 11.
[0055] Or such as Figure 10 As shown, the inner support part 11 is an inner pressure ring and is located on the inner side of the upper end of the flexible bag body 2. The inner support part 11 is supported on the outer support part 12. The inner support part 11 is provided with an upward-opening slot 112. The outer support part 12 is equipped with an outer pressure ring 13. The outer pressure ring 13 is pressed into the slot 112 from the outside of the flexible bag body 2 and cooperates with the slot 112, thereby fixing the flexible bag body 2.
[0056] The connection structure between the frame 1 and the flexible bag 2 can also adopt an external fixing structure, which is the same as in Embodiment 1. The frame 1 is located on the outside of the flexible bag 2 and is continuously fixed to the flexible bag 2 by existing welding or bonding methods.
[0057] Alternatively, the connection structure between frame 1 and flexible bag 2 can be achieved by fixing flexible bag 2 using existing mechanical fastening methods such as easy-pull buckles.
