An adaptive elastic drawstring waterproof bag

Abstract

This utility model relates to the field of waterproof bag technology and discloses an adaptive elastic drawstring waterproof bag, including a bag body with an opening at the top and a sealing cap movably inserted into the opening. This adaptive elastic drawstring waterproof bag, through the setting of the tightening component, prevents the soft material at the bag opening from directly bearing the extrusion force of the toothed ring. The rigid sealing cap must first be inserted into the opening, and its surface, with an installation groove that matches the toothed ring, provides a compression reference surface. Then, rotating the knob drives the worm gear fixed to it to rotate within the rotating groove of the moving block. Through the meshing transmission between the worm gear and the toothed ring, the toothed ring moves centripetally along the opening axis, pressing the soft bag opening, sandwiched between the inner wall of the toothed ring and the outer wall of the sealing cap's installation groove, into the groove to achieve tightening. Reverse rotation of the knob allows the toothed ring to move centrifugally to loosen the bag opening, and a limiting ring on one side of the moving block restricts the radial displacement of the worm gear. The sealing cap also shapes the bag opening, ensuring stable adjustment.

Description

Technical Field

[0001] This utility model relates to the field of waterproof bag technology, and in particular to an adaptive elastic drawstring waterproof bag. Background Technology

[0002] The self-adaptive elastic drawstring waterproof bag is a portable storage container that combines dynamic elasticity adjustment with high-efficiency waterproof performance. Its core design goal is to solve three major pain points of traditional storage bags through structural innovation: unstable sealing, limited usage scenarios, and low flexibility in adapting to items. It is widely used in outdoor travel, daily storage, sports and fitness and other scenarios, providing users with a storage solution that is adjustable to fit items, leak-proof and seepage-proof, and convenient to use.

[0003] However, existing self-adaptive elastic drawstring waterproof bags have the following disadvantages: (1) Some traditional rope-type or buckle-type drawstrings are prone to problems such as being too loose when tightened, leading to sealing failure, being too tight and difficult to loosen, or the bag opening shifting during adjustment. (2) Some traditional waterproof bags only focus on waterproof function and do not provide sufficient physical and hygiene protection for the items inside. If fragile items are stored, they are easily damaged by external impact and friction. If clothing, towels and other fabrics are stored, bacteria will easily grow and odors will be produced if the bags are sealed for a long time.

[0004] Therefore, this utility model provides an adaptive elastic drawstring waterproof bag. Utility Model Content

[0005] The problem solved by this utility model is to provide a highly practical adaptive elastic drawstring waterproof bag, which solves the problem mentioned in the background art that some traditional rope or buckle drawstring bags and some traditional waterproof bags only focus on waterproof function.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: an adaptive elastic drawstring waterproof bag, comprising a bag body, an opening at the top of the bag body, a sealing cap movably inserted into the opening, an installation groove on the surface of the sealing cap, a tightening component on the surface of the bag body, and a protective component inside the bag body; The tightening assembly includes a toothed ring fitted onto the outer wall of the bag opening. The toothed ring is adapted to the mounting groove. A movable block is slidably connected to the surface of the toothed ring. The movable block has a sliding groove and a rotating groove inside, which are interconnected. A worm gear is rotatably connected inside the rotating groove. Both ends of the worm gear extend to the outside of the movable block. A knob is fixedly connected to one end of the worm gear extending to the outside of the movable block. The protective component includes a waterproof layer disposed inside the bag body, an inner protective lining layer disposed on one side of the waterproof layer, and an antibacterial layer fixedly connected to one side of the inner protective lining layer.

[0007] Optionally, a fixing ring is fixedly connected to the surface of the bag body. The fixing ring is circular and provides stable support for the subsequent installation of the lifting component, preventing the surface of the bag body from tearing due to stress and improving the load-bearing capacity of the structure.

[0008] Optionally, the surface of the fixing ring is provided with a lifting rope. The lifting rope is made of nylon. The nylon lifting rope, together with the fixing ring, is convenient to carry by hand or hang, wear-resistant and tensile-resistant, and meets the carrying needs of outdoor and daily scenarios.

[0009] Optionally, a handle is fixedly connected to the top of the sealing cover, and a pull handle is fixedly connected to the surface of the handle. The handle on the top of the sealing cover allows for quick insertion and removal of the sealing cover, simplifying the operation steps for taking and putting in items and improving ease of use.

[0010] Optionally, the surface of the bag body is provided with grooves, and the number of grooves is six. The six grooves on the surface of the bag body increase the grip friction, prevent slipping when carrying, and enhance the structural stability of the bag body surface.

[0011] Optionally, a limiting ring is fixedly connected to one side of the moving block. A limiting hole is formed on the surface of the limiting ring. The limiting hole is adapted to the worm gear. The limiting ring adapts to the worm gear through the limiting hole to limit its radial displacement, avoid meshing failure, and ensure stable and reliable tension adjustment.

[0012] This utility model provides an adaptive elastic drawstring waterproof bag, which has the following beneficial effects: 1. This self-adaptive elastic drawstring waterproof bag, through the setting of the tightening component, prevents the soft material at the bag opening from directly bearing the extrusion force of the toothed ring. The rigid sealing cap must first be inserted into the opening, and its surface, with an installation groove that matches the toothed ring, provides a compression reference surface. Then, turning the knob drives the worm gear fixed to it to rotate in the rotating groove of the moving block. Through the meshing transmission between the worm gear and the toothed ring, the toothed ring moves centrifugally along the opening axis, pressing the soft bag opening sandwiched between the inner wall of the toothed ring and the outer wall of the sealing cap installation groove into the groove to achieve tightening. Turning the knob in the opposite direction allows the toothed ring to move centrifugally to loosen the bag opening, and the limiting ring on one side of the moving block can limit the radial displacement of the worm gear. The sealing cap can also shape the bag opening to ensure stable adjustment.
