[0011] Compared with the prior art, the advantages of this utility model are: the structure of this utility model is scientific and reasonable, and it is safe and convenient to use. 1. Equipped with operating components, the contact fixing plate is pushed downward by the gravity of the object, and the inner limiting sleeve provides lateral protection. At this time, it works with the telescopic fixing groove and the bottom support fixing cavity to elastically deform, realizing the internal air pressure rise and air pressure distribution according to the object's placement position, forming a uniform force distribution position. Then, the bottom support dispersion belt pulls the outer and inner limiting sleeves simultaneously, and with the deformation of the auxiliary support cavity, the force is further dispersed. Through bottom dispersion support and side protection support, the overall strength is improved. With the hollow treatment, the thickness of the plastic bag can be adjusted, reducing the use of plastic bag raw materials and lowering its manufacturing cost.

[0016] Example: Figure 1-4 As shown, this utility model provides a technical solution: an ultra-thin, high-toughness, anti-static packaging plastic bag, including an outer limiting sleeve 1, and an operating component 2 is provided on the side of the outer limiting sleeve 1. Operating component 2 includes an inner limit treatment sleeve 201, a contact fixing plate 202, a telescopic fixing groove 203, an auxiliary support cavity 204, a bottom support dispersion belt 205, an operating handle belt 206, a transverse support bar 207, a bending traction belt 208, and a bottom support fixing cavity 209; An inner limit treatment sleeve 201 is installed inside the outer limit treatment sleeve 1. A contact fixing piece 202 is installed at the bottom of the inner side of the inner limit treatment sleeve 201. The cross-sections of the outer limit treatment sleeve 1 and the inner limit treatment sleeve 201 are both rectangular, and the longitudinal section of the contact fixing piece 202 is arc-shaped, so as to realize multi-segment linkage closure treatment and ensure the stability of the plastic bag fixation. The top and bottom ends of the contact fixing plate 202 are provided with several telescopic fixing grooves 203 at equal intervals, and an auxiliary support cavity 204 is provided between the outer limiting sleeve 1 and the inner limiting sleeve 201. A bottom support fixing cavity 209 is provided on the inner side of the contact fixing plate 202; Several bottom support dispersion strips 205 are equidistantly bonded to the bottom side of the outer limiting sleeve 1. The length and width of the contact fixing piece 202 are equal to the length and width of the inner side of the inner limiting sleeve 201. The longitudinal section of the bottom support dispersion strip 205 is U-shaped, which realizes the stable restriction and load-bearing protection at the bottom and improves the overall load-bearing capacity. The top of the outer limiting sleeve 1 and the inner limiting sleeve 201 are equipped with operating handles 206. A transverse support bar 207 is installed at the bottom of the side of the operating handle 206, and a curved traction belt 208 is installed at the top of the transverse support bar 207. The side of the curved traction belt 208 is bonded to the inner side of the operating handle 206. There are two operating handles 206, two transverse support bars 207 and two curved traction belts 208 to achieve stable support and coordinated operation.

[0017] A linkage component 3 is provided on the side end of the outer limit processing sleeve 1; Linkage component 3 includes a side limiting elastic sheet 301, a limiting auxiliary strip 302, a diagonal bracing belt 303, an air elastic cavity 304, and a closing limiting strip 305; Several side-limiting elastic plates 301 are symmetrically bonded at equal intervals to the top of the outer limiting sleeve 1. The outer limiting sleeve 1, the bottom support dispersion strip 205 and the side-limiting elastic plates 301 are bonded with limiting auxiliary strips 302 at their side ends. The cross-section of the limiting auxiliary strips 302 is U-shaped, which realizes lateral support and side end protection. The bottom end of the horizontal support bar 207 is welded with a diagonal brace 303; An air elastic cavity 304 is provided between the inner limiting sleeve 201 and the diagonal brace 303. A closing limiting strip 305 is bonded to the bottom end of the diagonal brace 303. The side end of the closing limiting strip 305 is bonded to the inner end of the inner limiting sleeve 201 to ensure the stability of the side end limiting and isolation engagement.

[0018] The working principle and usage of this utility model are as follows: When using the packaging plastic bag, when the item is placed inside the inner limiting sleeve 201 at the contact fixing piece 202 position, the user holds the operating handle 206, which drives the side limiting elastic piece 301 and the diagonal bracing belt 303 to pull the outer limiting sleeve 1 and the inner limiting sleeve 201 upwards simultaneously. At this time, under the action of the item's gravity, the telescopic fixing groove 203 of the contact fixing piece 202 extends and retracts, changing the shape of the contact fixing piece 202, and cooperating with the outer limiting sleeve 1 and the inner limiting sleeve 201. The airflow inside the auxiliary support cavity 204 and the bottom support fixing cavity 209 between the sleeves 201 achieves an overall shape change, and the internal load-bearing capacity is improved through pneumatic compression. The airflow disperses the overall stress position, and the bending elasticity limit makes the overall stress more uniform. When the plastic bag is under stress and gravity is downward, the downward pull is dispersed to the side of the outer limit treatment sleeve 1 by multiple bottom support dispersion belts 205, realizing bottom stress dispersion treatment. Through the tension dispersion treatment, the load-bearing capacity and overall toughness of the plastic bag are improved. At the stress position of the operating handle 206, the tension at the position of the operating handle 206 is dispersed by the transverse support bar 207 and the curved traction band 208. The connection between the operating handle 206 and the outer limit treatment sleeve 1 is strengthened by the limiting auxiliary bar 302. The deformation of the diagonal brace 303 and the closing limit bar 305 is combined with the fixed air pressure restriction inside the air elastic cavity 304 to ensure that the top of the plastic bag always presents a triangular cone shape when pulled, thereby improving its stress position and ensuring the stability of its stress dispersion.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
