Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum compression bags, in particular to a vacuum compression bag. Background Art

[0002] Vacuum compression packaging involves placing a product into an airtight container and then removing the air inside to achieve a predetermined vacuum level. Because the vacuum container is highly depressurized, the lack of air creates a hypoxic effect, making it difficult for microorganisms to survive. This effectively extends the shelf life of food and prevents mold and spoilage. It's also used for packaging items like quilts and clothing. By removing the air from the quilts and clothing, atmospheric pressure compresses the expanded items, reducing their volume and saving space. This also protects against dust, mold, moisture, and insects.

[0003] After searching, the Chinese patent with announcement number CN220032683U discloses a vacuum compression bag, including a bag body with a zipper and an exhaust component arranged on the bag body. The bag body is provided with a fabric layer and a heat-sealable film layer from the outside to the inside, and an adhesive layer is provided between the fabric layer and the film layer for bonding the two. The fabric layer is a woven fabric layer with the fineness of the warp yarn and the weft yarn both being 50D to 90D and the fabric T number being 75 to 125 threads per square centimeter.

[0004] The vacuum compression bags in the above-mentioned prior art can meet the needs of users to a certain extent, but there are still some shortcomings in actual applications. For example, when the vacuum compression bags are not needed, they are usually folded and placed in a drawer or other special storage box or storage bag. However, such a folding method will easily cause cracks or holes in the corners of the curved parts of the storage bag over a long period of time, thus affecting the reuse of the vacuum compression bags.

[0005] In view of the problems mentioned in the background technology, the purpose of the present invention is to provide a vacuum compression bag to solve the problems mentioned in the background technology.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] A vacuum compression bag comprises: a compression bag body, wherein the outer surface of the compression bag body near the bag opening is provided with a vacuum exhaust port with a cover, a fixing mechanism is provided at the lower end of the compression bag body, a winding tube is fixedly mounted on the outer surface of the compression bag body away from the bag opening, the end of the winding tube is slidably connected to a handle, a clamping hole is provided on the inner side of the handle, and the inner side of the winding tube is clamped to one of the clamping holes on the outer side of the handle through the limiting mechanism;

[0009] The limiting mechanism includes an installation cavity, which is symmetrically opened inside the winding tube. The inner side of the installation cavity is slidably connected to the limiting plate. The lower end of the limiting plate is fixedly installed with a clamping rod. The clamping end of the clamping rod slides through the inner wall of the installation cavity and is clamped into one of the clamping holes on the outside of the handle. A pull rod is fixedly installed on the side of the limit plate away from the clamping rod. A groove is opened on the outer surface of the winding tube. The end of the pull rod away from the limit plate slides and extends into the inner side of the groove to fix a pull block. A spring is provided on the outer side of the pull rod.

[0010] As a preferred technical solution, sliding grooves are symmetrically provided on the inner side of the installation cavity, and the limiting plate and the sliding grooves on the inner wall of the installation cavity are slidably connected.

[0011] As an optimal technical solution, the engaging end of the clamping rod is spherical, a buckle groove is provided on one side of the cut groove close to the end of the winding tube, and one end of the pull block is arranged directly above the buckle groove.

[0012] As an optimal technical solution, the outer side of the handle is symmetrically provided with a limiting groove, and the inner wall of the end of the winding tube is symmetrically fixed with a limiting block, and the limiting block and the limiting groove are slidably connected.

[0016] In summary, the present invention has the following beneficial effects:

[0017] First, after the compression bag body is laid flat, it can be easily rolled up by combining it with a rolling tube with a handle. After rolling up, the Velcro loop tape near the opening of the compression bag body is bonded to the Velcro hook tape on the compression bag body. This flattened storage method prevents the surface of the compression bag body from being damaged by twists and turns. This can greatly extend the service life of the compression bag body.

[0018] Secondly, by depressing the pull block, the pull block drives the clamping rod at the limit plate to separate from the current handle clamping hole through the pull rod. Then, after the handle is pulled out, when the clamping end of the clamping rod corresponds to another clamping hole on the outside of the handle, the limit plate is pushed to slide in the installation cavity through the spring reset, and the clamping rod on the limit plate is clamped into the clamping hole after the handle is pulled out. Conversely, after the compression bag body is rolled up, the handle can be pushed into the rolling tube and fixed in the same way, so that the handle of the rolling tube can be used conveniently.

[0025] refer to Figures 1 to 5The vacuum compression bag described in this embodiment includes: a compression bag main body 1, a vacuum exhaust port 2 with a cover on the outer surface of the compression bag main body 1 near the bag opening, a fixing mechanism 3 is provided at the lower end of the compression bag main body 1, a winding tube 4 is fixedly installed on the outer surface of the compression bag main body 1 away from the bag opening, and a handle 5 is slidably connected to the end of the winding tube 4. A clamping hole 6 is opened on the inner side of the handle 5, and the inner side of the winding tube 4 is clamped with one of the clamping holes 6 on the outer side of the handle 5 through a limiting mechanism 11; a sealing structure is also provided at the opening of the compression bag main body 1, and the sealing structure of the compression bag main body 1 can be tightened by a sealing clip to achieve the sealing of the compression bag main body 1. This function is an existing technical structure of the compression bag main body 1 currently available on the market, so it will not be described in detail here;

[0026] The fixing mechanism 3 includes a first fixing film layer 302, which is bonded to the lower end of the compression bag body 1, and a Velcro hook surface tape 301 is bonded to the side of the first fixing film layer 302 away from the compression bag body 1. The lower end of the compression bag body 1 is bonded to a second fixing film layer 303, and the side of the second fixing film layer 303 away from the compression bag body 1 is bonded to the Velcro fleece surface tape 304. When the compression bag body 1 is not in use, the compression bag body 1 can be laid flat and then combined with the rewinding tube 4 with the handle 5 to conveniently rewind the compression bag body 1. After rewinding, the Velcro fleece surface tape 304 near the opening of the compression bag body 1 can be bonded to the Velcro hook surface tape 301 on the compression bag body 1. Through this flattened storage method, when the compression bag body 1 is stored, no tortuous edges and corners will appear on the surface of the compression bag body 1. Therefore, the problem of damage caused by tortuosity on the surface of the compression bag body 1 can be avoided to a large extent, thereby greatly enhancing the service life of the compression bag body 1 to a certain extent.

[0027] The limiting mechanism 11 includes an installation cavity 111, which is symmetrically arranged inside the winding tube 4. The inner side of the installation cavity 111 is slidably connected to the limiting plate 117. The lower end of the limiting plate 117 is fixedly installed with a clamping rod 116. The clamping end of the clamping rod 116 slides through the inner wall of the installation cavity 111 and is clamped in one of the clamping holes 6 on the outside of the handle 5. A pull rod 115 is fixedly installed on the side of the limiting plate 117 away from the clamping rod 116. A groove 112 is provided on the outer surface of the winding tube 4. The end of the pull rod 115 away from the limiting plate 117 slides into the groove 112 and is fixedly installed with a pull block 113. A spring 114 is sleeved on the outer side of the pull rod 115. When the handle 5 is pulled out, the pull block 113 is pulled so that the pull block 113 drives the clamping rod 116 at the limit plate 117 to separate from the current clamping hole 6 of the handle 5 through the pull rod 115. Then, after the handle 5 is pulled out, when the clamping end of the clamping rod 116 corresponds to another clamping hole 6 outside the handle 5, the spring 114 is reset to push the limit plate 117 to slide in the installation cavity 111, and the clamping rod 116 on the limit plate 117 is clamped into the clamping hole 6 after the handle 5 is pulled out. Conversely, after the compression bag body 1 is rolled up, the handle 5 can be pushed into the winding tube 4 and fixed in the same way, so that the handle 5 of the winding tube 4 can be used conveniently.

[0028] refer to Figure 5 A sliding groove 14 is symmetrically opened on the inner side of the installation cavity 111. The limiting plate 117 and the sliding groove 14 on the inner wall of the installation cavity 111 are slidingly connected. By opening the sliding groove 14 on the inner side of the installation cavity 111, the limiting plate 117 can slide inside the installation cavity 111.

[0029] refer to Figure 2 and Figure 5 The snap-in end of the clamping rod 116 is spherical, and a buckle groove 10 is provided on one side of the end of the groove 112 close to the winding tube 4. One end of the pull block 113 is provided directly above the buckle groove 10. By providing the buckle groove 10 at the groove 112, the pull block 113 can be conveniently buckled for operation.

[0030] refer to Figure 2 and Figure 5 The outer side of the handle 5 is symmetrically provided with a limiting groove 9, and the inner wall of the end of the winding tube 4 is symmetrically fixed with a limiting block 12. The limiting block 12 and the limiting groove 9 are slidably connected. Through the limiting groove 9 at the handle 5, the limiting sliding can be performed at the limiting block 12 of the winding tube 4. This makes it convenient to use the handle 5 while preventing the handle 5 from falling off the winding tube 4.

[0031] refer to Figure 4A groove 7 is provided at one end of the handle 5, and a pull handle 8 is fixedly installed on the inner side of the groove 7. The outer surface of the pull handle 8 is provided with stripes 701. By installing the pull handle 8 with stripes 701 in the groove 7 at the handle 5, the handle 5 can be easily pulled out of the winding tube 4 for use.

[0032] refer to Figure 3 The outer side of the Velcro loop tape 304 is sewn with a peeling block 13, which is arranged at one end of the Velcro loop tape 304 away from the second fixed film layer 303. The peeling block 13 at the Velcro loop tape 304 can be used to easily tear the Velcro loop tape 304 from the Velcro hook tape 301.

[0033] refer to Figure 2 The side of the rolling tube 4 facing the compression bag main body 1 is fixedly installed with a connecting block 15, and the side of the connecting block 15 away from the rolling tube 4 is adhered to the upper surface of the compression bag main body 1. The rolling tube 4 can be conveniently fixed to the compression bag main body 1 through the connecting block 15 at the lower end of the rolling tube 4; because the compression bag main body 1 will be wrinkled as a whole in the compressed state, the side of the compression bag main body 1 away from the opening adopts a convex structure, and this convex part does not belong to the storage space of the compression bag main body 1, and can be understood as the edge part of the bag, and this part is connected to the connecting block 15 of the rolling tube 4, which can avoid the negative effects caused by wrinkles, such as: the installation of the rolling tube 4 is not stable enough, it is easy to damage, etc.; in addition, a separate connecting strip can also be used here to directly connect with the outer wall of the rolling tube 4, and the effect is the same.

[0034] Principle and advantages of use: During use, when storing the compression bag body 1, the compression bag body 1 is laid flat, and then the compression bag body 1 can be conveniently rolled up by combining the rolling tube 4 with the handle 5. After rolling up, the Velcro loop tape 304 near the opening of the compression bag body 1 is bonded to the Velcro hook tape 301 on the compression bag body 1;

[0035] When using the handle 5, the pull block 113 is pulled, so that the pull block 113 drives the clamping rod 116 at the limit plate 117 to separate from the current handle 5 clamping hole 6 through the pull rod 115. Then, after the handle 5 is pulled out, when the clamping end of the clamping rod 116 corresponds to another clamping hole 6 outside the handle 5, the spring 114 is reset to push the limit plate 117 to slide in the installation cavity 111, and the clamping rod 116 on the limit plate 117 is clamped into the clamping hole 6 after the handle 5 is pulled out. Conversely, after the compression bag body 1 is rolled up, the handle 5 can be pushed into the rolling tube 4 and fixed in the same way.
