Description

Technical Field

[0001] The utility model relates to the technical field of air column bags, in particular to a high-cushioning air column bag with sealing performance. Background Art

[0002] Air column bags, also known as cushioning air column bags, inflatable bags, bubble column bags, and columnar inflatable bags, are new packaging materials filled with natural air in the 21st century. They can prevent the extrusion, vibration, and friction of items during transportation, and have a certain protective effect on fragile and delicate objects. Therefore, the items can be cushioned and protected by the fully covered air column, reducing the loss rate of product transportation. After the air column is inflated, the cushioning air column bag can provide close protection for the product, and is recyclable, low-cost, and pollution-free. Therefore, in the field of transportation, cushioning air column bags have been widely used.

[0003] A search revealed a patent application for a double-layer air bag with the publication number CN221069315U that states, "The double-layer air bag comprises an inner bag and an outer bag, forming a double-layer air bag structure. The inner cavity and protective pad are combined to improve the air bag's impact resistance. Furthermore, the inner bag can be removed from the outer bag, allowing the inner and outer bags to be used independently, thereby increasing the bag's flexibility."

[0004] However, the above solution still has certain shortcomings in actual use. The air column bag of this technical solution is formed by folding the air column bag and then heat-sealing it during production. Therefore, there is a crease at the center of the bottom of the air column bag. Therefore, the thickness of the air column at the bottom of the air column bag is relatively small, resulting in insufficient support force for the bottom of the article. When an external force collision occurs, the bottom of the article is subjected to friction and damage, thereby reducing the protection effect on the article. Summary of the Invention

[0005] The utility model provides a high-sealing cushioning air column bag to solve the problems in the background technology.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a sealed high-cushion air bag, comprising an air bag structure, wherein the bottom end of the air bag structure is movably connected to a bottom cushioning structure, wherein the bottom cushioning structure comprises an external shell, wherein an internal embedded box is fixedly connected to the internal end of the external shell, an insertion port is provided between the external shell and the internal embedded box, and the bottom end of the air bag structure is located inside the insertion port;

[0007] Three groups of buffer mechanisms are provided inside the embedded box, and the buffer mechanism includes a buffer box, a spring slide rod is fixedly installed on the inner wall of the buffer box, and the surface of the spring slide rod is slidably connected to two sliders, and the top end of the slider is rotatably connected to a hinge rod, and the two hinge rods are hinged to each other. The other end of the hinge rod extends to the interior of the displacement plate, and a buffer plate is fixedly installed on the top end of the displacement plate. The buffer plate is located on the outside of the buffer box.

[0008] Furthermore, an anti-slip pad is provided on the inner wall of the plug port, and the anti-slip pad is a soft silicone pad.

[0009] Furthermore, a placement opening is provided inside the embedded box, and the buffer box is located inside the placement opening.

[0010] Furthermore, a bottom pad is provided at the bottom end of the external shell, and the bottom pad is a silicone rubber pad.

[0011] Furthermore, the displacement plate is internally slidably connected to two guide blocks, and one end of the hinged rod away from the slider is hinged to the guide blocks.

[0012] Furthermore, the air column bag structure includes a columnar air bag and a connecting air bag, and two adjacent columnar air bags are connected to each other via the connecting air bag.

[0013] Compared with the prior art, the present invention provides a highly sealed air column bag with the following benefits:

[0014] The air bag with high sealing performance and high cushioning performance is provided with a bottom cushioning structure. The air bag structure and the outer shell are effectively connected by utilizing the plug-in interface structure provided between the outer shell and the embedded box, so that the bottom gap of the air bag structure is filled. The cushioning mechanism can then provide protective cushioning for objects inside the air bag structure.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1-4 The utility model discloses a sealed high-cushion air column bag, comprising an air column bag structure 1, wherein the bottom end of the air column bag structure 1 is movably connected with a bottom buffer structure 2.

[0022] The air column bag structure 1 includes a columnar air bag 101 and a connecting air bag 102 , and two adjacent columnar air bags 101 are connected to each other via the connecting air bag 102 .

[0023] The bottom buffer structure 2 includes an external shell 201 , an internal box 202 is fixedly connected to the external shell 201 , an insertion port 203 is provided between the external shell 201 and the internal box 202 , and the bottom end of the air column bag structure 1 is located inside the insertion port 203 .

[0024] Three groups of buffer mechanisms 205 are provided inside the embedded box 202. A placement opening is opened inside the embedded box 202, and the buffer box 207 is located inside the placement opening. The buffer mechanism 205 includes a buffer box 207, and a spring slide 208 is fixedly installed on the inner wall of the buffer box 207. The surface of the spring slide 208 is slidably connected to two sliders 209. The top of the slider 209 is rotatably connected to a hinged rod 210. The two hinged rods 210 are hinged to each other. The other end of the hinged rod 210 extends to the inside of the displacement plate 212. The inside of the displacement plate 212 is slidably connected to two guide blocks 211. The end of the hinged rod 210 away from the slider 209 is hinged to the guide block 211. The top of the displacement plate 212 is fixedly installed with a buffer plate 213, and the buffer plate 213 is located on the outside of the buffer box 207.

[0025] By setting up a bottom buffer structure 2, the plug-in interface 203 opened between the outer shell and the embedded box 202 can be used to effectively connect the air column bag structure 1 and the outer shell, so that the bottom gap of the air column bag structure 1 is filled, and then combined with the buffer mechanism 205, the objects inside the air column bag structure 1 can be protectively buffered, so that when the objects inside the air column bag are rubbed and collided, the bottom buffer structure 2 buffers and protects the objects, thereby reducing the probability of damage to the objects, thereby improving the protection effect of the objects.

[0026] Specifically, an anti-slip pad 204 is provided on the inner wall of the plug port 203 , and the anti-slip pad 204 is a soft silicone pad.

[0027] In this embodiment, the anti-slip pad 204 is provided inside the plug port 203 to make the connection between the plug port 203 and the air column bag structure 1 tighter, and then the item to be protected is placed between the air column bag structure 1 and the embedded box 202, so that the item is wrapped and cushioned.

[0028] Specifically, a bottom pad 206 is provided at the bottom end of the external shell 201, and the bottom pad 206 is a silicone rubber pad.

[0029] In this embodiment, the bottom pad 206 can effectively cushion the bottom end of the external shell 201 .

[0030] When in use, first insert the air column bag structure 1 into the interior of the insertion port 203. The anti-slip pad 204 provided inside the insertion port 203 can make the connection between the insertion port 203 and the air column bag structure 1 tighter. Then, place the item to be protected between the air column bag structure 1 and the embedded box 202, so that the item is wrapped and cushioned.

[0031] When an object rubs or collides, the object will drive the buffer plate 213 to move, prompting the buffer plate 213 to drive the displacement plate 212 to slide synchronously, and the movement of the displacement plate 212 will drive the two guide blocks 211 to slide relative to each other on the inner side of the displacement plate 212, so that the guide blocks 211 drive the hinge rod 210 to deflect at an angle during the displacement process, so that the other end of the hinge rod 210 will drive the slider 209 to slide along the surface of the spring slide rod 208, prompting the damping spring on the spring slide rod 208 to be compressed, causing the damping spring to begin to deform and absorb the impact force. Therefore, the rotation process of the hinge rod 210 is the process of buffering the vibration impact force.

[0032] To sum up, the air-sealed high-cushion air bag, by setting a bottom buffer structure 2, utilizes the plug-in interface 203 opened between the outer shell and the embedded box 202 to effectively connect the air bag structure 1 and the outer shell, so that the bottom gap of the air bag structure 1 is filled, and then cooperates with the buffer mechanism 205 to provide protective buffering for objects inside the air bag structure 1, so that when the objects inside the air bag are rubbed and collided, the bottom buffer structure 2 buffers and protects the objects, thereby reducing the probability of damage to the objects, thereby improving the protection effect of the objects.
