Utility Model Content

[0005] The purpose of the utility model is to provide a three-layer thickened bubble bag to solve the problem that the existing bubble bags proposed in the above background technology are generally disposable items after being inflated when put into use. If there are too many goods to be transported, the disposable use will make it impossible to recover them after unloading, so the next continued use will increase the cost, resulting in the inability to effectively reduce the cost of use and transportation costs.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a three-layer thickened bubble bag, comprising a bag body and a placement layer arranged inside the bag body, a buffer layer is fixedly connected to both sides of the inner wall of the placement layer, an expansion tube is arranged inside the bag body and can be expanded by filling with gas to reduce the collision coefficient, a control block is fixedly connected to the bottom of the bag body, a one-way block is arranged inside the control block and can inflate the expansion tube, and a deflation tube with a deflation effect is arranged inside the control block.

[0007] Preferably, the expansion tube is arranged inside the bag body, a plurality of expansion balls are arranged on both sides of the surface of the bag body, and connecting tubes connected to the expansion balls are arranged on both sides of the surface of the expansion tube.

[0008] Preferably, a connecting pipe is provided inside the expansion pipe, and the connecting pipe is fixedly connected to the bottom end of the expansion pipe.

[0009] Preferably, a working groove is provided on the surface of the control block, a fixed hose is fixedly connected to the inside of the control block, and one end of the fixed hose passes through the inside of the control block and extends to the inside of the working groove, and one end of the fixed hose is fixedly connected to the connecting pipe.

[0010] Preferably, the one-way block is fixedly connected to one end of the fixed hose away from the connecting pipe, a cavity is provided inside the one-way block, and fixing rods are fixedly connected to both sides of the inner wall of the cavity.

[0011] Preferably, the rod walls of the two fixing rods are rotatably connected with a one-way plate, and the two one-way plates are fixedly connected with springs on opposite sides of the inner wall of the cavity.

[0012] Preferably, a passing block is fixedly connected to one side of the inner wall of the cavity, a passing groove is provided inside the passing block, and an inflating balloon is fixedly connected to one side of the surface of the one-way block away from the fixed hose.

[0013] Preferably, the vent pipe is arranged inside the control block, and the vent pipe passes through the inside of the control block and extends to the outside where a sealing plug is fixedly inserted.

[0014] The technical effects and advantages of the utility model are as follows: when the utility model is transporting packaged goods, the inflated balloon is squeezed to allow air to enter the interior of the fixed hose through the set one-way block, and then the one-way block uses two internal springs to squeeze the one-way plate, so that the spring and the one-way plate cooperate to form a one-way channel, so that the expansion tube drives multiple expansion balls to expand so as to protect the internal goods. When the packaging and transportation are completed, the sealing plug is finally pulled out to contact the expansion protection, which effectively avoids the fact that most bubble bags are disposable items, thereby greatly reducing the use cost and transportation cost.

DETAILED DESCRIPTION

[0022] 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.

[0023] The utility model provides Figure 1-6 The three-layer thickened bubble bag shown in the figure comprises a bag body 1 and a placement layer 2 arranged inside the bag body 1, and buffer layers 3 are fixedly connected to both sides of the inner wall of the placement layer 2, and an expansion tube 4 which can be expanded by filling gas to reduce the collision coefficient is arranged inside the bag body 1, and a control block 5 is fixedly connected to the bottom of the bag body 1, and a one-way block 6 which can inflate the expansion tube 4 is arranged inside the control block 5, and a deflation tube 7 with a deflation effect is arranged inside the control block 5. When the utility model is used for the transportation of packaged goods, the air is squeezed by the inflated balloon 606 so that the air enters the interior of the fixed hose 501 through the one-way block 6, and then the one-way block 6 squeezes the one-way plate 603 by two springs 607 inside, so that the spring 607 cooperates with the one-way plate 603 to form a one-way channel, so that the expansion tube 4 drives multiple expansion balls 402 to expand so as to protect the goods inside, and when the packaging and transportation are completed, the sealing plug 701 is finally pulled out to contact the expansion protection, which effectively avoids the fact that most bubble bags are disposable products, thereby greatly reducing the use cost and the transportation cost.

[0024] like Figure 1-3As shown, the expansion tube 4 is arranged inside the bag body 1, and multiple expansion balls 402 are arranged on both sides of the surface of the bag body 1. The expansion balls 402 can protect the internal goods from damage caused by collision. Connecting tubes 401 connected to the expansion balls 402 are arranged on both sides of the surface of the expansion tube 4. A connecting tube 403 is arranged inside the expansion tube 4, and the connecting tube 403 is fixedly connected to the bottom end of the expansion tube 4. The connecting tube 403 plays a connecting role that allows air to enter the interior to produce an expansion effect.

[0025] like Figure 4-6 As shown, a working groove 502 is provided on the surface of the control block 5, a fixed hose 501 is fixedly connected inside the control block 5, and one end of the fixed hose 501 passes through the inside of the control block 5 and extends to the inside of the working groove 502, one end of the fixed hose 501 is fixedly connected to the connection pipe 403, the one-way block 6 is fixedly connected to the end of the fixed hose 501 away from the connection pipe 403, a cavity 601 is provided inside the one-way block 6, both sides of the inner wall of the cavity 601 are fixedly connected to fixed rods 602, the rod walls of the two fixed rods 602 are rotatably connected to the one-way plates 603, and the two one-way plates 603 are opposite to the inner wall of the cavity 601 on both sides. They are all fixedly connected with a spring 607. The ejection of the spring 607 can create a one-way channel effect inside the cavity 601 without air flowing in, thereby ensuring the use effect of the bubble bag. A through block 604 is fixedly connected to one side of the inner wall of the cavity 601. A through groove 605 is opened inside the through block 604. An inflated balloon 606 is fixedly connected to the side of the surface of the one-way block 6 away from the fixed hose 501. The deflation pipe 7 is arranged inside the control block 5, and the deflation pipe 7 passes through the interior of the control block 5 and extends to the outside where a sealing plug 701 is fixedly inserted. The air inside can flow out by pulling out the sealing plug 701, thereby allowing multiple uses.

[0026] Working principle of the utility model: when the utility model is used, the inflated balloon 606 is first squeezed to allow the air driven by the inflated balloon 606 to enter the inside of the one-way block 6. When the air enters the cavity 601, it will push out the one-way plate 603 supported by the spring 607. At this time, the one-way plate 603 will rotate on the rod wall of the fixed rod 602, and the air will successfully pass through the groove 605 and enter the inside of the fixed hose 501. When the inflated balloon 606 no longer delivers air, the two springs 607 will respectively support the two one-way plates 603, so that a one-way channel is formed through the groove 605.

[0027] Then, the gas entering through the fixed hose 501 will enter the interior of the expansion tube 4 through the connecting tube 403. When the expansion tube 4 expands, it drives multiple expansion balls 402 to expand, and at the same time forms protection for the goods inside the placement layer 2. Finally, just pull out the sealing plug 701 to release the internal gas, so that it can be reused.

[0028] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. 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.
