Description

Technical Field

[0001] This utility model relates to the field of packaging bag technology, specifically a high-strength tensile packaging bag. Background Technology

[0002] Packaging bags are bags used to package various items and are widely used in daily life and industrial production. Their main purpose is to facilitate the transportation and storage of goods.

[0003] Chinese Utility Model Announcement No. CN221758242U includes a packaging bag body. A reinforcing seal is fixedly installed on the upper outer surface of the packaging bag body. Reinforcing rings are fixedly installed on the left and right sides of the outer surface at both ends of the reinforcing seal. A lifting rope is provided at the upper part of the packaging bag body. Handle structures are fixedly installed on the outer walls at both ends of the lifting rope. The handle structure includes a rubber sleeve and a velvet sleeve. There are four sets of reinforcing rings. The lifting rope passes through the four sets of reinforcing rings. The velvet sleeve is fixed to the outer wall of the rubber sleeve. There are two sets of handle structures, with each set containing one set of rubber sleeve and one set of velvet sleeve. This utility model describes a high-strength, tensile-resistant packaging bag. The reinforcing seal, reinforcing rings, and lifting rope improve strength and tensile strength, extending service life. The handle structure improves comfort and reduces injury to the user's hands.

[0004] The applicant discovered some shortcomings in the use of the patent: because the lifting rope is an integral structure, the lifting rope will block the top two ends of the bag to a certain extent, affecting the taking out and placing of items, and when the lifting rope is damaged and replaced, the whole bag needs to be replaced.

[0005] Therefore, this utility model designs a high-strength, tensile-resistant packaging bag to solve the problems existing in the prior art. Utility Model Content

[0006] The purpose of this invention is to provide a high-strength, tensile-resistant packaging bag to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a high-strength tensile-resistant packaging bag, comprising: a bag body, two rope holes at the top of each end of the bag body, a pull rope passing through the two rope holes, a fixing cylinder installed on the top of the inner wall at each end of the bag body, an insertion hole at each end of the fixing cylinder, the two ends of the pull rope entering the fixing cylinder through the insertion hole and being knotted, a fixing block provided inside the fixing cylinder to cover the knotted pull rope, the two ends of the pull rope passing through the rope hole and the insertion hole entering the fixing cylinder and being knotted to complete the fixation, and then the fixing block is fixed inside the fixing cylinder to cover the knotted area and improve the appearance. By setting pull ropes on both sides of the bag body, the pull ropes will not cover the top of the bag body, thereby avoiding affecting the taking and placing of items, and when the pull rope is damaged and replaced, only the damaged pull rope needs to be replaced, saving replacement costs.

[0008] Preferably, the outer side wall of the fixing block is provided with external threads, and the inner side wall of the fixing cylinder is provided with internal threads. The stability of the fixing block in the fixing cylinder can be improved by the internal and external threads.

[0009] Preferably, two crescent-shaped grooves are provided on one side of the fixing block, through which the operator can insert two fingers into the crescent-shaped grooves to facilitate rotating the fixing block.

[0010] Preferably, a reinforcing ring is provided inside the rope hole, which can protect the rope hole.

[0011] Preferably, the bag body has a reinforced edge seal at the top, which is made of polyester material, which has good tensile strength and abrasion resistance.

[0012] Preferably, a cotton sleeve is provided in the middle of the outer side wall of the pull rope, which can improve the comfort of the operator's fingers;

[0013] Preferably, the bag body includes a base layer, and both sides of the base layer are provided with nylon layers. Nylon is a synthetic fiber with good tensile strength and abrasion resistance.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model provides drawstrings on both sides of the bag, which do not obstruct the top of the bag, thus avoiding any impact on taking out and placing items. Moreover, when the drawstrings are damaged and need to be replaced, only the damaged drawstring needs to be replaced, saving replacement costs.

[0016] 2. By setting up a fixed tube, the two ends of the pull rope enter the fixed tube through the insertion hole, are knotted inside the fixed tube for fixation, and then the knot is covered by a fixing block, which can improve the overall aesthetics. Attached Figure Description
