Description

Technical Field

[0001] This utility model relates to the field of tote bag technology, and in particular to a waterproof tote bag. Background Technology

[0002] A tote bag is a simple bag, usually with two handles, for carrying by hand. Tote bags are made from materials such as paper, plastic, non-woven fabric, and industrial cardboard. They are commonly used by businesses for product packaging or as promotional gifts for customers. Many fashion-conscious individuals also incorporate tote bags into their clothing choices, matching them with their outfits.

[0003] In order to improve their durability, existing tote bags generally have a certain degree of elasticity. Therefore, users tend to take advantage of this characteristic to fill the tote bags with as many items as possible for convenience. Since it is difficult to control the degree of elastic deformation of the tote bag, it is easy for the tote bag to tear, which will lead to damage. To address this, we provide a waterproof tote bag. Utility Model Content

[0004] To address the problem in the aforementioned background technology that the deformation of a tote bag is difficult to control when containing items, leading to the tote bag being prone to tearing and damage, this utility model provides a waterproof tote bag.

[0005] This utility model is achieved using the following technical solution: a waterproof tote bag, comprising:

[0006] The tote bag body has handles on both upper sides, which are fixedly connected to the tote bag body via connectors. Connecting plates are provided on both sides of the inner cavity of the tote bag body and are fixedly connected to the inner wall of the tote bag body. Connecting rod one is symmetrically hinged to the outer sides of one connecting plate, and two sets of connecting rod two are symmetrically hinged to the outer sides of the other connecting plate. Connecting rod one and the two sets of connecting rod two are hinged to each other on the same side. Four sets of springs are also symmetrically fixedly connected between the two sets of connecting plates.

[0007] As a further improvement to the above solution, the tote bag body includes, from bottom to top, a moisture-proof layer, a base layer, a fiber reinforcement layer, a waterproof layer, and a protective layer.

[0008] As a further improvement to the above solution, a wear-resistant layer is provided at the bottom of the moisture-proof layer.

[0009] As a further improvement to the above solution, a flexible protective pad is also added to the outside of the connecting plate.

[0010] As a further improvement to the above solution, the moisture-proof layer is non-woven fabric, the waterproof layer is TPU laminated fabric, and the protective layer is composite woven kraft paper.

[0011] As a further improvement to the above solution, the connecting plate is made of rigid plastic.

[0012] As a further improvement to the above solution, the wear-resistant layer is PVC leather.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model allows a folded tote bag to be automatically opened by pulling two sets of connecting plates to both sides, with hinges between connecting rod one and one side connecting plate, and between two sets of connecting rod two and the other side connecting plate. At this time, the spring is stretched, facilitating the loading of items into the tote bag. Simultaneously, after releasing the connecting plates, the spring's rebound action clamps the items inside the tote bag, preventing friction between harder items and the tote bag during movement, thus preventing wear. When the two sets of connecting plates are pulled perpendicular to connecting rod one and the two sets of connecting rod two, they can no longer move, thereby controlling the elastic deformation of the tote bag and preventing it from tearing due to overloading, effectively protecting the tote bag.

[0015] 2. When the items inside the tote bag are completely removed, the spring rebound, the hinge between connecting rod one and the connecting plate on one side, the hinge between the two sets of connecting rod two and the connecting plate on the other side, and the hinge between connecting rod one and the two sets of connecting rod two make the two sets of connecting plates automatically move closer together, thereby realizing the automatic folding of the tote bag, which is highly practical.

[0022] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0023] Example 1:

[0024] Please combine Figure 1-4 A waterproof tote bag according to this embodiment includes:

[0025] The tote bag body 1 has handles 2 on both upper sides, which are fixedly connected to the tote bag body 1 by connectors 3. Connecting plates 4 are provided on both sides of the inner cavity of the tote bag body 1 and are fixedly connected to the inner wall of the tote bag body 1. The connecting plates 4 are made of rigid plastic. Connecting rods 5 are symmetrically hinged to the outer sides of one connecting plate 4, and two sets of connecting rods 6 are symmetrically hinged to the outer sides of the other connecting plate 4. Connecting rods 5 on the same side are hinged to the two sets of connecting rods 6. Four sets of springs 7 are also symmetrically fixedly connected between the two sets of connecting plates 4. The main body 1 includes, from bottom to top, a moisture-proof layer 101, a base layer 102, a fiber reinforcement layer 103, a waterproof layer 104, and a protective layer 105. The bottom of the moisture-proof layer 101 is provided with a wear-resistant layer 106. The moisture-proof layer 101 is made of non-woven fabric, which can prevent the main body 1 of the tote bag from getting damp. The waterproof layer 104 is made of TPU laminated fabric, which can improve the waterproof effect of the main body 1 of the tote bag. The protective layer 105 is made of composite woven kraft paper, which can prevent the main body 1 of the tote bag from being scratched. The wear-resistant layer 106 is made of PVC leather, which can prevent the main body 1 of the tote bag from being worn due to friction between the items and the main body 1 of the tote bag.

[0026] The implementation principle of a waterproof tote bag in this embodiment is as follows: By pulling two sets of connecting plates 4 to both sides, and with the hinged action between connecting rod 1 5 and one side connecting plate 4, and the hinged action between two sets of connecting rods 2 6 and the other side connecting plate 4, the folded tote bag can be automatically opened. At this time, the spring 7 will be stretched, making it easier to put items into the tote bag. At the same time, after releasing the connecting plates 4, the rebound action of the spring 7 will clamp the items inside the tote bag, preventing friction between harder items and the tote bag during movement, which could cause wear and tear on the tote bag. When the two sets of connecting plates 4 are pulled to be perpendicular to the first connecting rod 5 and the two sets of second connecting rods 6, the two sets of connecting plates 4 can no longer move. This controls the elastic deformation of the tote bag and prevents it from bursting due to overloading. This effectively protects the tote bag. After the items inside the tote bag are completely removed, the spring 7, the hinge between the first connecting rod 5 and one side connecting plate 4, the hinge between the two sets of second connecting rods 6 and the other side connecting plate 4, and the hinge between the first connecting rod 5 and the two sets of second connecting rods 6 cause the two sets of connecting plates 4 to automatically move closer together, thus enabling the automatic folding of the tote bag.

[0027] Example 2:

[0028] Based on Embodiment 1, this embodiment is further improved by adding a flexible protective pad 8 to the outside of the connecting plate 4, which can protect the contained items and prevent them from being damaged by pressure.

[0029] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
