[0035] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0036] The utility model provides the following preferred embodiments:

[0037] Embodiment 1, as Figure 1-Figure 8 As shown, the environmentally friendly buffer document bag comprises a main bag body 11, and also comprises a retracting mechanism and a packaging mechanism. The packaging mechanism and the retracting mechanism are respectively located at the upper and lower ends of the main bag body 11. The packaging mechanism is used to seal the opening of the main bag body 11, and the retracting mechanism is used to roll up the bottom end of the main bag body 11, thereby changing the size of the inner cavity of the main bag body 11, making it convenient to store documents of different sizes, and also preventing the document bag from being too large, so that the documents are easily shaken inside the document bag during transportation, which is easy to cause damage to the four corners and edges of the documents;

[0038] The retracting and unwinding mechanism includes a reel 16, two plug blocks 19, two fixed plates 28, two connecting components and two telescopic components. The reel 16 is fixedly mounted at the bottom end of the main bag body 11. The two plug blocks 19 are respectively plugged into the two ends of the reel 16. Each connecting component is located between the reel 16 and an plug block 19. The connecting component is used to connect the reel 16 and the plug block 19 together. Each fixed plate 28 is located on one side of an plug block 19. Each telescopic component is located between a fixed plate 28 and an plug block 19. The telescopic component is used to adjust the position of the fixed plate 28 so that the distance between the fixed plate 28 and the reel 16 is adjustable, thereby fixing the main bag body 11 of the reeled portion to prevent it from loosening.

[0039] By providing a retractable mechanism, the main bag body 11 can be retracted and released according to the size of the document, so that the size of the main bag body 11 can match the size of the document, thereby preventing the document bag from being too large, and the document from shaking inside the document bag during transportation, which can easily cause damage to the four corners and edges of the document;

[0040] The packaging mechanism includes a sealing tongue 30, a first-layer sealing component and a second-layer sealing component. The sealing tongue 30 is fixed to one side of the top of the main bag body 11. The first-layer sealing component is located between the sealing tongue 30 and the main bag body 11. The first-layer sealing component can achieve a primary seal on the top opening of the main bag body 11. The second-layer sealing component is arranged on the inner wall of the top of the main bag body 11. The second-layer sealing component can achieve a secondary seal on the top opening of the main bag body 11, thereby achieving a two-layer sealing effect on the main bag body 11. At the same time, when the first-layer sealing component is damaged after the document bag is used once, the second-layer sealing component can still be used to seal the document bag, so that the document bag can be recycled for many times, achieving an environmentally friendly effect.

[0041] Preferably, a release paper 32 is provided on the surface of the main bag body 11. When in use, the express delivery bill can be attached to the release paper 32. After the document bag is used once, the release paper 32 can be used to conveniently remove the express delivery bill to avoid leakage of user information. At the same time, it can also avoid damage to the main bag body 11 when removing the express delivery bill.

[0042] like Figure 1-Figure 8 As shown, each connecting assembly includes a first plug hole 18, an annular buckle 20 and an annular groove 21. The first plug hole 18 is opened at the end of the winding roller 16, the plug block 19 is plugged into the inside of the first plug hole 18, and the plug block 19 and the first plug hole 18 are interference fit, the annular buckle 20 is fixedly installed on the inner wall of the first plug hole 18, the annular groove 21 is fixed to the outer wall of the plug block 19, and the annular groove 21 and the annular buckle 20 are snap-fitted;

[0043] During use, when the plug block 19 needs to be installed, the plug block 19 is inserted into the first plug hole 18. At this time, the annular groove 21 is inserted into the annular buckle 20 to position the plug block 19 so that the plug block 19 can be stably installed in the winding roller 16.

[0044] like Figure 1-Figure 8 As shown, each telescopic assembly includes an avoidance groove 22, a second plug hole 23, a slide bar 24, a limit plate 25, a spring 26 and a spring 27;

[0045] The avoidance groove 22 is opened at one end of the plug block 19, and the second plug hole 23 is opened at the other end of the plug block 19. The avoidance groove 22 is connected to the second plug hole 23, and the slide bar 24 is slidably arranged inside the second plug hole 23. Specifically, one end of the slide bar 24 is arranged through the avoidance groove 22, and the top of the slide bar 24 is fixedly connected to one end of the spring sheet 27, and the fixing plate 28 is fixedly installed at the bottom end of the spring sheet 27. That is, when the slide bar 24 slides inside the second plug hole 23, the spring sheet 27 is used to fix the slide bar 24 to the bottom end of the spring sheet 27. The sheet 27 can drive the fixed plate 28 to move, and the limit plate 25 is fixedly installed at the bottom end of the slide bar 24. It should be noted here that the outer diameter of the limit plate 25 is smaller than the inner diameter of the avoidance groove 22, that is, the limit plate 25 can move into the inside of the avoidance groove 22. The spring 26 is sleeved on the slide bar 24, and the two ends of the spring 26 are fixedly connected to the limit plate 25 and the avoidance groove 22 respectively. In the initial state, the spring 26 is in a natural state, and the bottom section of the fixed plate 28 is in contact with the surface of the winding roller 16;

[0046] When in use, firstly, the excess part of the main bag body 11 is rolled up to the surface of the winding roller 16 in a certain direction, and then the limiting plate 25 is pushed to move in the direction of the spring sheet 27, and the limiting plate 25 can push the slide bar 24 to move. At this time, the spring 26 is compressed, and when the slide bar 24 moves, it can drive the fixing plate 28 to move through the spring sheet 27, so that the fixing plate 28 can be located above the main bag body 11 after rolling up, and at the same time, the plug block 19 is inserted into the inside of the first plug hole 18 to fix the plug block 19. Finally, the limiting plate 25 is released, and the fixing plate 28 can be driven to reset under the action of the spring 26, so that the bottom end of the fixing plate 28 can be tightly fixed to the main bag body 11 after rolling up on the winding roller 16;

[0047] After the main bag body 11 is rolled up, the inner cavity of the main bag body 11 can be adapted to the size of the document, thereby preventing the main bag body 11 from being much larger than the document, causing the document to shake inside the main bag body 11 .

[0048] like Figure 1-Figure 8 As shown, the cross section of the fixing plate 28 is arranged in an arc shape, and the arc-shaped fixing plate 28 can better position the main bag body 11 rolled up onto the winding roller 16 .

[0049] like Figure 1-Figure 8As shown, a sealing component includes a tape 31 and an easy-tear tape 33. The tape 31 is adhered to one side of the sealing tongue 30. When the main bag body 11 is packaged, the other side of the tape 31 is adhered to the main bag body 11, so that one end of the sealing tongue 30 can be connected to the main bag body 11. At the same time, because the other end of the sealing tongue 30 is fixed to the main bag body 11, the sealing of the end of the main bag body 11 can be achieved. The easy-tear tape 33 is located on the surface of the sealing tongue 30 and is integrally formed with the sealing tongue 30. The easy-tear tape 33 is a prior art and is not specifically described here. When it is necessary to take out the documents inside the main bag body 11, the easy-tear tape 33 is pulled so that the sealing tongue 30 can be torn into two sections, thereby releasing the sealing tongue 30 from blocking the end of the main bag body 11, making it convenient to take out the documents.

[0050] like Figure 1-Figure 8 As shown, the two-layer sealing component includes two Velcros 29, and the two Velcros 29 are respectively located on both sides of the inner wall of the main bag body 11. The two Velcros 29 are respectively a child Velcro and a mother Velcro. The child and mother Velcro can be used to directly bond the opening of the main bag body 11 together to achieve a sealing effect. At the same time, when the file bag is used once and a layer of the sealing component is damaged, the two Velcros 29 can still be used to seal the file bag, so that the file bag can be recycled for multiple times to achieve an environmentally friendly effect.

[0051] like Figure 1-Figure 8 As shown, the inner wall of the main bag body 11 is provided with a bubble film 15 for buffering. By providing a layer of bubble film 15 inside the main bag body 11, a buffering effect can be achieved. When transporting documents, the bubble film 15 can be used to protect the documents and reduce the occurrence of document damage.

[0052] like Figure 1-Figure 8 As shown, the main bag body 11 includes cardboard 14, fireproof paper 13, and waterproof film 12. The cardboard 14, fireproof paper 13, and waterproof film 12 are connected in sequence from the inside to the outside. The cardboard 14 can achieve a waterproof effect, the fireproof paper 13 can achieve a fireproof effect, and the waterproof film 12 can increase the hardness of the document bag to achieve a protective effect.

[0053] The beneficial effects of the present invention are specifically embodied in that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
