[0024] In order to further understand the content of the present application, the present application will be described in detail with reference to the drawings.

[0025] Please refer to Figures 1-4 The present application provides a technical scheme: a food packaging bag with adjustable internal space, comprising a packaging bag body 1, handle 2 is attached to both sides of the packaging bag body 1, a storage box 3 is arranged at one end of the packaging bag body 1, a mouth 6 is formed on one side of the storage box 3, the packaging bag body 1 is slidably connected inside the mouth 6, a winding shaft 11 is rotatably connected inside the storage box 3, a connecting ring 15 is fixedly installed on one side of the packaging bag body 1 extending into the storage box 3, the winding shaft 11 passes through the connecting ring 15, an eccentric winding rod 16 is fixedly connected to the surface inside the storage box 3 where the winding shaft 11 is located, and a handle 12 is fixedly installed on one end of the winding shaft 11 extending outside the storage box 3.

[0026] Rotating the handle 12 makes the winding shaft 11 rotate, and in turn makes the eccentric winding rod 16 rotate around the winding shaft 11, and in turn winds the packaging bag body 1 on the winding shaft 11 and the eccentric winding rod 16, and in turn facilitates winding the packaging bag body 1 into the inside of the storage box 3, and in turn facilitates adjusting the space size of the packaging bag body 1, and in turn facilitates adjusting according to the size of food, and in turn facilitates containing food of different sizes.

[0027] The side of the storage box 3 is fixedly provided with a fixed box 10, the fixed box 10 is rotatably sleeved on the surface of the winding shaft 11, the winding shaft 11 is fixedly sleeved with a ratchet 19 on one end in the fixed box 10, the inside of the fixed box 10 is rotatably connected with a rotating rod 13, one end of the rotating rod 13 extending to the outside of the fixed box 10 is fixedly provided with a swing handle 14, one end of the rotating rod 13 in the fixed box 10 is fixedly sleeved with a ratchet pawl 18, the ratchet pawl 18 is engaged with the ratchet on the ratchet 19, the surface of the rotating rod 13 is movably sleeved with a second torsion spring 17, one end of the second torsion spring 17 close to the ratchet pawl 18 is fixedly connected with the ratchet pawl 18, and the other end of the second torsion spring 17 away from the ratchet pawl 18 is fixedly connected with the inner wall of the fixed box 10.

[0028] When the winding shaft 11 rotates, the ratchet 19 rotates with the winding shaft 11, and the ratchets on the ratchet 19 continuously press the ratchet pawl 18, so that the ratchet pawl 18 rotates around the rotating rod 13, and the second torsion spring 17 deforms, when the ratchet pawl 18 enters between two ratchets, the ratchet pawl 18 is reset by the torsion of the second torsion spring 17, and the ratchet 19 is fixed, preventing the packaging bag body 1 wound on the winding shaft 11 and the eccentric winding rod 16 from sliding out of the inside of the storage box 3.

[0029] Swing the swing handle 14 to rotate the rotating rod 13, so that the ratchet pawl 18 is disengaged with the ratchet on the ratchet 19, and the winding shaft 11 can be reversed, so that the packaging bag body 1 wound on the winding shaft 11 and the eccentric winding rod 16 is pulled out of the inside of the storage box 3, and the length of the packaging bag body 1 is adjusted, and the size of the inside space of the packaging bag body 1 is adjusted, avoiding single adjustment, causing the packaging bag body 1 and the food to be mismatched, and maximizing the matching degree of the packaging bag body 1 and the food.

[0030] The two rotating shafts 9 are rotatably connected with the storage box 3, the two rotating shafts 9 are fixedly provided with the connecting plates 7, the two rotating shafts 9 are movably sleeved with the first torsion springs 8, one end of the two first torsion springs 8 close to the storage box 3 is fixedly connected with the storage box 3, and the other end of the two first torsion springs 8 close to the two connecting plates 7 is fixedly connected with the two connecting plates 7, one side of the two connecting plates 7 is fixedly provided with the connecting rings 15, and the two connecting rings 15 are fixedly provided with the cleaning rollers 4.

[0031] The cleaning roller 4 is in contact with the surface of the packaging bag body 1 by the torsion of the first torsion spring 8, and the surface of the packaging bag body 1 is cleaned when the packaging bag body 1 is shrunk into the inside of the storage box 3, thereby preventing dust from entering the inside of the storage box 3, reducing the difficulty of cleaning the storage box 3, and improving the appearance and cleanliness of the surface of the packaging bag body 1.

[0032] Working principle:

[0033] Rotating the handle 12, the winding shaft 11 is rotated, and the eccentric winding rod 16 is rotated around the winding shaft 11, and the packaging bag body 1 is wound on the winding shaft 11 and the eccentric winding rod 16, and then the packaging bag body 1 is conveniently rolled into the inside of the storage box 3, and the space size of the packaging bag body 1 is conveniently adjusted. When the winding shaft 11 rotates, the ratchet 19 rotates with the winding shaft 11, and the ratchet on the ratchet 19 continuously presses the pawl 18, and the pawl 18 rotates around the rotating rod 13, and the second torsion spring 17 is deformed. When the pawl 18 enters between two ratchets, the pawl 18 is reset by the torsion of the second torsion spring 17, and the ratchet 19 is fixed, preventing the packaging bag body 1 wound on the winding shaft 11 and the eccentric winding rod 16 from sliding out of the inside of the storage box 3.

[0034] Swinging the swing handle 14, the rotating rod 13 is rotated, and the pawl 18 and the ratchet on the ratchet 19 are disengaged, and then the winding shaft 11 can be reversed, and the packaging bag body 1 wound on the winding shaft 11 and the eccentric winding rod 16 is pulled out of the inside of the storage box 3, and then the packaging bag body 1 is conveniently adjusted to a specific length, and then the inside space size of the packaging bag body 1 is conveniently adjusted.

[0035] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and not for limiting the present application, although the foregoing detailed description of the present application is made with reference to the foregoing embodiments, for the skilled in the art, it still can be modified, or part of the technical features of the equivalent replacement, within the spirit and principles of the present application, any modification, equivalent replacement, improvement, etc., should be included in the scope of protection of the present application.
