[0019] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0020] like Figure 1-4As shown, the utility model is a portable plastic food packaging bag, comprising a bag body 1, handles 2 are provided on both sides of the upper part of the bag body 1, two symmetrical first connecting blocks 3 are provided on the upper inner end of the bag body 1, two equidistantly arranged fixing grooves 4 are provided on the inner side of the first connecting block 3, a second connecting block 5 is provided on the upper inner end of the bag body 1 away from the first connecting block 3, a fixing block 6 matching the fixing groove 4 is provided on the second connecting block 5, the fixing block 6 can be plugged into the fixing groove 4, and the first connecting block 3 and the second connecting block 5 can be stably connected through the mutual cooperation between the fixing block 6 and the fixing groove 4, so as to achieve the purpose of sealing the opening of the bag body 1, and an exhaust component 7 is provided on the side of the bag body 1 below the first connecting block 3, and the gas inside the bag body 1 can be discharged through the exhaust component 7.

[0021] The fixing block 6 has a side close to the first connecting block 3 which is configured as an arc surface. The configuration of the arc surface makes it easier to insert the fixing block 6 into the fixing groove 4 .

[0022] The exhaust assembly 7 includes a connecting ring 71, which is fixedly connected to the bag body 1. A fixing ring 72 is provided on the side of the connecting ring 71 away from the bag body 1. A fixing plate 73 is provided in the fixing ring 72 near the connecting ring 71. A guide rod 74 is inserted in the middle of the fixing plate 73, and the guide rod 74 is movably connected to the fixing plate 73. The end of the guide rod 74 away from the connecting ring 71 is fixedly connected to the cover plate 75. The guide rod 74 is located between the cover plate 75 and the fixing plate 73 and is sleeved with a spring 76. The two ends of the spring 76 are respectively fixedly connected to the cover plate 75 and the fixing plate 73. The fixing plate 73 is located on the outer side of the guide rod 74 and is provided with a plurality of through holes 77 arranged in a matrix. When the bag body 1 is squeezed, the gas inside the bag body 1 enters the fixing ring 72 through the through holes 77, thereby increasing the internal pressure of the fixing ring 72. Under the action of pressure, the cover plate 75 is separated from the fixing ring 72, so that the gas inside the bag body 1 can be discharged through the connected connecting ring 71 and the fixing ring 72.

[0023] A sealing gasket 78 is provided on one side of the cover plate 75 close to the guide rod 74 . The sealing gasket 78 can seal the contact surface between the cover plate 75 and the fixing ring 72 , thereby effectively improving the sealing performance of the exhaust assembly 7 .

[0024] The side walls on both sides of the bag body 1 are provided with folds 8, and the provision of the folds 8 makes it easier to fold the bag body 1.

[0025] Specifically, in the utility model, the fixing block 6 can be inserted into the fixing groove 4, and the fixing block 6 and the fixing groove 4 cooperate with each other, so that the first connecting block 3 and the second connecting block 5 can be stably connected, thereby achieving the purpose of sealing the opening of the bag body 1. After the bag body 1 carries food, when the bag body 1 is squeezed, the gas inside the bag body 1 enters the fixing ring 72 through the through hole 77, thereby increasing the internal pressure of the fixing ring 72. Under the action of pressure, the cover plate 75 is separated from the fixing ring 72, so that the gas inside the bag body 1 can be discharged through the connected connecting ring 71 and the fixing ring 72.

[0026] 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.
