Description

Technical Field

[0001] This utility model relates to the field of bag sealing strip technology, specifically to a tear-resistant bag sealing strip. Background Technology

[0002] In today's travel and logistics landscape, bags and luggage serve as crucial containers for carrying goods, and their performance directly impacts the safety of those items and the user experience. Sealing strips, as an essential component of bags and luggage, play a decisive role in their waterproof, dustproof, moisture-proof, and heat-insulating properties. With increasing travel frequency and the booming development of the logistics industry, the performance requirements for bag and luggage sealing strips are becoming increasingly stringent.

[0003] In daily use, bags are frequently subjected to complex external forces such as handling, squeezing, and friction. During handling, the sealing strip may be torn due to scratches from sharp objects or accidental pulling; during transportation, the stacking and collision of bags can also easily damage the sealing strip. Once the sealing strip is torn, its sealing performance will be greatly reduced, leading to the risk of the contents of the bag being exposed to moisture, dust, or even damage. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tear-resistant bag sealing strip, which can effectively solve the problems in the existing technology.

[0005] This utility model provides a tear-resistant bag sealing strip, including a sealing strip with a hollow structure and a central groove inside. The sealing strip has bottom holes on both sides of its bottom end, and an inner groove is formed on the outer wall of the central groove. An inner plate is fixed in the central groove, and the inner side of the inner plate is fixedly engaged with a tear-resistant membrane. A fastening structure is fixed in the bottom hole, and the fastening structure includes a through rod and locking rings sleeved on both ends of the through rod.

[0006] Furthermore, multiple sets of side strips are fixed on the outer side wall of the inner panel, and multiple sets of inner grooves are equidistantly arranged, with the side strips fixedly engaged in the inner grooves.

[0007] Furthermore, the inner wall of the insert plate protrudes inward in an arc shape, and the inner wall of the insert plate makes interference contact between the tear-resistant membrane and the inner wall of the central groove.

[0008] Furthermore, circular grooves are provided on both the front and rear sides of the bottom hole, and threaded grooves are provided on both sides of the through rod. The locking ring is engaged and sleeved on both sides of the through rod and fixed in the circular groove.

[0009] Furthermore, the tear-resistant membrane is made of HDPE membrane material.

[0010] Furthermore, multiple sets of anti-slip strips are fixed inside the sealing strip.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] This utility model features a sealing strip-inset plate-tear-resistant membrane structure, where the tear-resistant membrane is an HDPE membrane structure. The inset plate structure can be interlocked with the inner groove of the central groove through its outer side strip, which can fix the position of the inset plate structure. Furthermore, through its protruding structural features, the tear-resistant membrane is secured in the central groove of the sealing strip. Therefore, the sealing strip and the internal tear-resistant membrane structure can improve tear strength.

[0013] In this device, the embedded plate and fastening structure are designed so that the fastening structure can be connected through the through rod. The through rod is fixed in the bottom hole of the sealing strip by the locking rings on both sides. Therefore, the embedded plate and through rod structure can improve the structural strength of the sealing strip. Attached Figure Description
