[0030] 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.

[0031] Reference Figure 1 - Figure 7As shown, the utility model provides a stretch-resistant packaging bag, comprising a packaging bag body 1, a handle 1 2 and a handle 2 3. The handle 1 2 and the handle 2 3 are sequentially installed on both sides of the top surface of the packaging bag body 1, a protective frame 1 4 is installed on the handle 1 2, and a protective frame 2 5 is installed on the handle 2 3;

[0032] The top surface of the protective frame 2 5 is provided with a mounting groove 13, and the side of the top surface of the protective frame 2 5 away from the protective frame 1 4 is provided with a receiving groove 12;

[0033] Recovery components 8 are installed on the front and rear side walls of the inner cavity of the storage tank 12, and a rotating shaft 7 is rotatably installed between the two recovery components 8. An isolation pad 9 is wrapped around the rotating shaft 7. The isolation pad 9 passes through the inner cavity of the storage tank 12 and extends to the outside of the protective frame 5;

[0034] The isolation pad 9 can be made of EVA foam, which has good cushioning and vibration isolation performance, resilience and tension resistance;

[0035] A plurality of positioning components 6 are slidably mounted on the side wall of the receiving groove 12 , and a plurality of through holes 11 are evenly opened on the side wall of the protective frame 5 . The through holes 11 are connected to the mounting groove 13 , and the handle 3 is mounted in the mounting groove 13 .

[0036] In a further embodiment, referring to Figure 1 - Figure 6 The recovery component 8 includes a cylindrical frame 801 and a scroll spring 803. The cylindrical frames 801 are respectively installed on the front and rear side walls of the inner cavity of the storage groove 12. The outer end of the scroll spring 803 is connected to the inner cavity side wall of the cylindrical frame 801, and the inner end of the scroll spring 803 is connected to the outer wall of the rotating shaft 7.

[0037] A positioning ring 802 is installed on one side of the inner cavity of the cylindrical frame 801, and a mounting ring 804 is installed on the positioning ring 802. A rotating shaft 7 is rotatably installed in the mounting ring 804;

[0038] When in use, the isolation pad 9 is pulled to drive the rotating shaft 7 to rotate. When the rotating shaft 7 rotates, the vortex spring 803 starts to accumulate force. Therefore, when the isolation pad 9 is not in use, under the action of the vortex spring 803, the vortex spring 803 drives the rotating shaft 7 to rotate and reset, thereby quickly rewinding the isolation pad 9 onto the outer wall of the rotating shaft 7.

[0039] In a further embodiment, referring to Figure 1 - Figure 6The positioning assembly 6 includes a plug-in rod 602. A plurality of plug-in rods 602 are slidably mounted on the side wall of the receiving groove 12. The plug-in rod 602 passes through the inner wall of the plug-in rod 602 and extends to the inner cavity of the mounting groove 13. A plug-in rod 602 is slidably mounted in the second through hole 11. A groove 604 is provided on the side of the plug-in rod 602 close to the second through hole 11. A positioning block 603 is symmetrically mounted on the side of the plug-in rod 602 with the groove 604. A limit ring 601 is mounted on the outer wall of the plug-in rod 602 away from the positioning block 603.

[0040] The side of the positioning block 603 away from the plug-in rod 602 is designed to be arc-shaped;

[0041] The plug rod 602 is located above the isolation pad 9. The isolation pad 9 is evenly provided with a plurality of through holes 10. The plug rod 602 is slidably installed in the through holes 10.

[0042] An isolation pad 9 is clamped between the positioning block 603 and the protective frame 2 5;

[0043] The two positioning blocks 603 on the plug rod 602 are pressed so that the two are squeezed against each other, so that the through hole 10 on the isolation pad 9 can smoothly pass through the two positioning blocks 603 and contact the outer wall of the protective frame 2 5. The isolation pad 9 is clamped and positioned under the action of the positioning blocks 603 and the protective frame 2 5.

[0044] Furthermore, when the positioning assembly 6 needs to be replaced after long-term use, use scissors to cut off the positioning block 603, and pull the limit ring 601 to drive the plug-in rod 602 to be pulled out from the through hole 2 11 and the protective frame 2 5, and plug the new plug-in rod 602 into the protective frame 2 5. Since the positioning block 603 is designed to be arc-shaped, it can quickly pass through the storage groove 12 and the through hole 2 11 when installing the positioning assembly 6.

[0045] In a further embodiment, referring to Figure 1 and Figure 7 , the inner cavity side wall of the packaging bag body 1 is evenly paved with a reinforcing cloth 14;

[0046] The reinforcing cloth 14 is made of glass fiber mesh cloth, which has extremely high strength and rigidity, thereby improving the tensile performance of the device.

[0047] The working principle of the utility model is as follows: when the device is used, first place the article in the packaging bag body 1, then pull the isolation pad 9, and Figure 7 Pull the middle route map, and finally make the through hole 10 on the isolation pad 9 correspond one to one with the through hole 2 11 on the protective frame 2 5;

[0048] Then, the two positioning blocks 603 on the plug rod 602 are pressed, so that the two are squeezed against each other, so that the through hole 10 on the isolation pad 9 can smoothly pass through the two positioning blocks 603 and contact the outer wall of the protective frame 2 5. Under the action of the positioning blocks 603 and the protective frame 2 5, the isolation pad 9 is clamped and positioned;

[0049] At this time, the isolation pad 9 will protect the bottom surface of the protection frame 2 5 and the protection frame 1 4, and improve the integrity between the protection frame 1 4 and the protection frame 2 5, making it easier for users to lift;

[0050] When the isolation pad 9 needs to be released, press the two positioning blocks 603 to remove the through hole 10 from between the positioning block 603 and the protective frame 2 5, and under the action of the spiral spring 803, the spiral spring 803 drives the rotating shaft 7 to rotate and reset, thereby quickly rewinding the isolation pad 9 onto the outer wall of the rotating shaft 7.

[0051] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
