DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides the following technical solutions: a food packaging bag, comprising an outer packaging bag 1 and a packaging bag support 2 connected to the outside of the outer packaging bag 1, a second-layer packaging bag 3 arranged in the outer packaging bag 1, and a sealing component 4, the outer packaging bag 1 is used, the packaging bag support 2 is used to support and protect the outer packaging bag 1, the packaging bag support 2 is designed to be symmetrical up and down and left and right, the second-layer packaging bag 3 is used to seal food, and the sealing component 4 is used to open or close the food packaging bag 1.

[0026] The packaging bag bracket 2 includes four groups of cylindrical brackets, a first cylindrical bracket 201, a second cylindrical bracket 202, a third cylindrical bracket 203 and a fourth cylindrical bracket. The top of the second cylindrical bracket 202 is connected to the first connecting rod bracket 204 and the first short connecting rod 205. The first short connecting rod 205 is rotatably connected to the second cylindrical bracket 202 and can rotate around the second cylindrical bracket 202. The first short connecting rod 205 is rotatably connected to the second short connecting rod 207 through the shaft 206. The first short connecting rod 205 and the second short connecting rod 207 can rotate around the shaft 206. A blocking block 208 is set on the inner side of one end of the first short connecting rod 205 close to the second short connecting rod 207. The blocking block 208 is used to limit the rotation angle of the first short connecting rod 205 and the second short connecting rod 207. When the first short connecting rod 205 and the second short connecting rod 207 rotate around the shaft 206 until the blocking block 208 contacts the second short connecting rod 207, the first short connecting rod 205 and the second short connecting rod 207 are The short link 207 stops rotating, achieving the effect of limiting the rotation of the first short link 205 and the second short link 207 to the extreme position. When the first short link 205 and the second short link 207 rotate to the extreme position as shown in the figure, the first short link 205 and the second short link 207 form an obtuse angle. When the packaging bag holder 2 is subjected to the force in the front and rear directions, the blocking block 208 limits the rotation of the first short link 205 and the second short link 207, so that the packaging bag holder 2 remains stationary, so that the device can support and protect the packaging bag and prevent it from being deformed by the force in the front and rear directions; through the action of the first link bracket 204, the device can support and protect the packaging bag and prevent it from being deformed by the force in the left and right directions. Through the action of the four groups of cylindrical brackets, the device can support and protect the packaging bag and prevent it from being deformed by the force in the up and down directions, so that the utility model can achieve the effect of supporting and protecting the packaging bag.

[0027] The sealing assembly 4 includes a left sealing strip 401 and a right sealing strip 402 which are arranged above the outer packaging bag 1. Two left rope holes 403 are arranged on the outer side of the left sealing strip 401. A hand rope 404 is arranged in the left rope hole 403 and can slide in the left rope hole 403. A round hemp rope 405 is arranged in the middle position of the hand rope 404 for facilitating pulling the hand rope 404. Elastic ropes 406 are connected to both ends of the hand rope 404. The outer ends of the elastic ropes 406 are connected to fixed blocks 407. The fixed blocks 407 are arranged at both ends of the left sealing strip 401. Two right rope holes 408 are arranged on the outer side of the right sealing strip 402. The left rope hole 403 and the right rope hole 408 are symmetrically arranged.

[0028] In a specific embodiment of the utility model, when it is necessary to support the packaging bag, the first short link 205 and the second short link 207 are rotated around the axis 206 to the position where the positioning block 208 contacts the second short link 207, so as to prevent the packaging bag from being deformed due to the forces in the front-to-back, left-to-right, and up-and-down directions; when it is necessary to fold the packaging bag, the push axis 206 moves in the direction close to the outer packaging bag 1, so as to drive the first short link 205 and the second short link 207 to rotate until the second cylindrical bracket 202 and the third cylindrical bracket 203 are in contact with each other, so that the outer packaging bag 1 is folded in the front-to-back direction, thereby achieving the effect of convenient storage and space saving.

[0029] When the packaging bag needs to be recycled, the second packaging bag 3 is removed to obtain a clean outer packaging bag 1, so that the utility model can achieve the effect of being reused.

[0030] When the packaging bag needs to be lifted, the round hemp rope 405 on the hand rope 404 in the left rope hole 403 and the right rope hole 408 is pulled upward with both hands at the same time. The elastic rope 406 is stretched longer, so that the hands can pass under the two hand ropes 404 at the same time to lift the packaging bag.

[0031] When the packaging bag is put down, the hand rope 404 returns to its original position under the action of the elastic rope 406, so that the utility model can achieve the effect that the hand rope can be stored and folded well without being tangled.

[0032] When the packaging bag needs to be sealed, the left and right sealing strips 401 and 402 are pressed together to seal the bag opening of the outer packaging bag 1.

[0033] Preferably, the round hemp rope 405 is set to a cylindrical shape, so that fingers can be easily inserted into the gap between the left sealing strip 404, the right sealing strip 402 and the round hemp rope 405, so as to facilitate pulling up the hand rope 404.

[0034] Preferably, the round hemp rope 405 is made of flax material. Rough materials are not easy to slip, and flax has high strength and is not easy to tear.

[0035] Preferably, the second-layer packaging bag 3 is made of high-density polyethylene, which has a wide operating temperature range, is protective, and is easy to tear and remove so that the packaging bag can be used again.

[0036] Preferably, the groove on the left sealing strip 401 and the protrusion on the right sealing strip 402 are made of PET material with high toughness, so that the left sealing strip 401 and the right sealing strip 402 can be used repeatedly.

[0037] Preferably, the outer packaging bag 1 is made of polyamide, which has good transparency, making it easy to observe the state of food in the outer packaging bag 1, and is heat-resistant, oil-resistant, and puncture-resistant, and can protect the second-layer packaging bag 3 arranged inside the outer packaging bag 1.

[0038] Furthermore, the second-layer packaging bag 3 and the outer-layer packaging bag 1 are connected together by a plurality of glue spots, so as to achieve the effect of fixing the position of the second-layer packaging bag 3 in the outer-layer packaging bag 1 .

[0039] Furthermore, the glue dispensing position is set at the position of the outer packaging bag 1 close to the left sealing strip 401 and the right sealing strip 402, so as to achieve the effect of facilitating the disassembly of the second packaging bag 3 and facilitating the secondary use of the packaging bag.
