Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of packing bag, more specifically relates to a food waterproof packing bag. BACKGROUND

[0002] At present, the food packing bag needing waterproof seal will set up multiple sealing strips at the bag mouth to realize waterproof seal, but when closing the sealing strip, the multiple sealing strips need to be operated, which is very inconvenient, and the sealing performance will be reduced or even invalid if the sticking of one or even multiple sealing strips is missed. SUMMARY

[0003] In view of the defects of the prior art, the utility model provides a food waterproof packing bag which can quickly close the bag mouth, and the sealing strip is tightly stuck, and the sealing waterproof performance is good.

[0004] To achieve the above object, the utility model provides the following technical scheme: a food waterproof packing bag, the bag mouth inside of packing bag is provided with a plurality of sealing strips, the bag mouth outside of packing bag is provided with positioning clamping mechanism, the positioning clamping mechanism includes first clamping plate, second clamping plate and fixed block, one end of first clamping plate and second clamping plate is hinged with fixed block, the fixed block is connected with the side of packing bag, first clamping plate and second clamping plate are located at the both sides of packing bag respectively, the free end between first clamping plate and second clamping plate is detachably connected, and the length of first clamping plate and second clamping plate is greater than the width of packing bag.

[0005] Further, the first clamping plate is provided with clamping grooves corresponding to the sealing strips inside the packing bag, and the second clamping plate is provided with clamping strips corresponding to the clamping grooves.

[0006] Further, the free end of the first clamping plate or the second clamping plate is provided with an elastic clamping plate, and the end of the elastic clamping plate is provided with a clamping hook.

[0007] Further, the first clamping plate and the second clamping plate are provided with a plurality of reinforcing ribs on the side away from the packing bag.

[0008] Compared with the prior art, the utility model has the beneficial effects that when the bag mouth of the packing bag needs to be closed, the clamping force generated by closing the first clamping plate and the second clamping plate is used to make the sealing strips inside the bag mouth stick to each other, so that the sealing strips are tightly stuck, and the bag mouth is quickly closed.

[0012] In the description of this utility model, it should be noted that the directional terms such as "center", "horizontal (X)", "longitudinal (Y)", "vertical (Z)", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this utility model.

[0013] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features. Thus, the use of "first" and "second" to define a feature may explicitly or implicitly include one or more of that feature. In the description of this utility model, "several" or "a number" means two or more, unless otherwise explicitly specified.

[0014] Reference Figure 1 and Figure 2 The present invention will be further described below.

[0015] A waterproof food packaging bag, wherein a plurality of sealing strips 2 are provided on the inner side of the bag opening of the packaging bag 1, and a positioning clamping mechanism is provided on the outer side of the bag opening of the packaging bag 1. The positioning clamping mechanism includes a first clamping plate 3, a second clamping plate 4 and a fixing block 5. One end of the first clamping plate 3 and the second clamping plate 4 are both hinged to the fixing block 5. The fixing block 5 is connected to the side of the packaging bag 1. The first clamping plate 3 and the second clamping plate 4 are respectively located on both sides of the packaging bag 1. The free ends of the first clamping plate 3 and the second clamping plate 4 are detachably connected. The length of the first clamping plate 3 and the second clamping plate 4 is greater than the width of the packaging bag 1.

[0016] like Figure 1 and Figure 2 As shown, when the bag opening of the packaging bag 1 needs to be closed, the clamping force generated by closing the first clamping plate 3 and the second clamping plate 4 makes the sealing strip 2 on the inside of the bag opening stick together, ensuring that the sealing strip 2 is tightly attached and the bag opening is quickly closed.

[0017] like Figure 2As shown, in this preferred embodiment, the first clamping plate 3 is provided with clamping grooves 6 corresponding to several sealing strips 2 inside the packaging bag 1, and the second clamping plate 4 is provided with clamping strips 7 corresponding to the clamping grooves 6.

[0018] Specifically, when the first clamping plate 3 and the second clamping plate 4 are closed, the sealing strip 2 on one side of the inside of the packaging bag 1 is aligned with the clamping groove 6, and the sealing strip 2 on the other side is aligned with the clamping strip 7, so that the sealing strip 2 can be more accurately attached.

[0019] like Figure 2 As shown, in this example, preferably, an elastic clamping plate 8 is provided on the free end of the first clamping plate 3 or the second clamping plate 4, and a hook 9 is provided at the end of the elastic clamping plate 8.

[0020] Specifically, the first clamping plate 3 and the second clamping plate 4 are fixed by hooking the other clamping plate with the hook 9. At the same time, the first clamping plate 3 and the second clamping plate 4 can be separated by bending the elastic clamping plate 8 by bending the hook 9.

[0021] like Figure 1 and Figure 2 As shown, in this example, preferably, the first clamping plate 3 and the second clamping plate 4 are provided with a number of reinforcing ribs 10 on the side away from the packaging bag 1, so as to reduce the degree of bending when the first clamping plate 3 and the second clamping plate 4 are closed, so as to apply effective pressure to the sealing strip 2.

[0022] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
