Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterproof bag technology, specifically to a sealing component for a waterproof bag. Background Technology
[0002] A waterproof bag is a bag specifically designed to protect items from water, sand, dust, and other environmental elements. It is typically used for outdoor activities, water sports, or extreme weather conditions. Made of waterproof materials such as PVC, TPU, or transparent film, it ensures that items inside remain dry when exposed to water. Waterproof bags are generally designed with strong-seal closures and waterproof zippers to effectively repel moisture. They are widely used for waterproofing electronic products such as mobile phones, wallets, and keys.
[0003] An existing waterproof mobile phone bag includes a rectangular pouch for holding the mobile phone. The pouch has a first opening at its top, and a clamping component for sealing the pouch is fixed at the first opening. Second openings are located on both sides of the pouch, and a transparent film is fixed and sealed to the pouch at each of the second openings. Compared to traditional methods that involve completely enclosing the entire bag within the pouch, the aforementioned technology, using a transparent film and pouch, significantly reduces the area requiring adhesive or heat pressing during connection, thereby reducing processing steps and simplifying manufacturing.
[0004] However, in actual use, because the sealing component of the waterproof bag can only hold and seal a single waterproof bag, when users need to carry multiple items (such as multiple mobile phones, wallets, keys, etc.) in the water, they can only put all these items into the same waterproof bag, which causes the items to rub against each other or become difficult to organize, thus affecting the convenience of use. Utility Model Content
[0005] This utility model proposes a sealing component for waterproof bags, which solves the problem that traditional sealing components can only hold a single waterproof bag, resulting in reduced ease of use.
[0006] The technical solution of this utility model is as follows: a sealing assembly for a waterproof bag, including a first clamping shell and a third clamping shell for sealing the waterproof bag, wherein a multi-layer sealing member for sealing multiple waterproof bags is provided between the first clamping shell and the third clamping shell, and the first clamping shell and the third clamping shell are detachably connected.
[0007] Furthermore, the two sides of the multi-layer sealing member abut against one side of the first clamping shell and the third clamping shell, respectively.
[0008] Furthermore, the first clamping shell, the multi-layer sealing component, and the third clamping shell are separate units.
[0009] Furthermore, both sides of the multi-layer sealing component are provided with positioning grooves, and the first clamping shell and the third clamping shell are provided with positioning posts on the side facing the multi-layer sealing component. Each positioning post is slidably connected to the inner wall of the corresponding positioning groove.
[0010] Furthermore, each of the positioning posts is cylindrical in shape, and the top of the positioning post facing the multi-layer sealing component is arc-shaped.
[0011] Furthermore, each of the multi-layer sealing components has a first fixing post on both sides, and a first clamping component is fixedly connected to the side of each first fixing post away from the multi-layer sealing component. The first clamping shell and the third clamping shell are each provided with a second fixing post on the side facing the first clamping component, and a second clamping component is fixedly connected to the side of each second fixing post close to the first clamping component.
[0012] Furthermore, the first clamping housing and the third clamping housing are detachably connected by a fixing component. The fixing component includes a hook and a bent portion, a handle portion, and a locking portion provided on the hook. Both sides of the first clamping housing and the multi-layer sealing component are provided with through holes, and arc-shaped blocks are fixedly connected to both sides of each through hole. Arc-shaped grooves are provided on both sides of the bent portion. One side of the hook is provided with an opening for the arc-shaped block to enter the arc-shaped groove. The side of the first clamping housing near the through hole is provided with a groove for engaging with the locking portion.
[0013] Furthermore, the first clamping housing has a receiving groove for placing the handle on the side near the through hole, and the groove is located at the bottom of the receiving groove.
[0014] Furthermore, one side of the handle extends to the outside of the first clamping housing, and the side of the handle is inclined.
[0015] Furthermore, the top of the positioning groove near the positioning post has a chamfer.
[0016] The working principle and beneficial effects of this utility model are as follows:
[0017] This invention features a first clamping shell, a third clamping shell, and multiple sealing components. The multiple sealing components can clamp and seal multiple waterproof bags. Additional waterproof bags allow users to place mobile phones or valuables, preventing items from rubbing against each other within the same bag, thus improving organization and ease of use.
[0018] Secondly, combining multiple waterproof bags together and then securing them with a first and third clamping shell makes them more convenient to carry, preventing the bags from separating and becoming difficult to organize. When in use, simply disassembling the first and third clamping shells allows for simultaneous opening or closing of multiple waterproof bags, saving time and effort.
[0019] In addition, multiple waterproof bags are tightly connected together by a first clamping shell, a third clamping shell, and multiple layers of sealing components, which reduces the possibility of a single waterproof bag accidentally falling off or being lost during use. This makes the waterproof bags less likely to be lost and better ensures that the waterproof bags are always with the user, thus ensuring the safety of the items inside. Attached Figure Description

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.
[0029] refer to Figure 1-6A sealing assembly for a waterproof bag includes a first clamping housing 1 and a third clamping housing 102 for sealing the waterproof bag. A multi-layer sealing member 101 for sealing multiple waterproof bags is provided between the first clamping housing 1 and the third clamping housing 102, and the first clamping housing 1 and the third clamping housing 102 are detachably connected.
[0030] The two sides of the multi-layer sealing member 101 abut against one side of the first clamping shell 1 and the third clamping shell 102, respectively. Abutting the first clamping shell 1, the multi-layer sealing member 101, and the third clamping shell 102 against each other can make the connection between them tighter and more stable, thereby ensuring the sealing of the opening and the overall performance of the waterproof bag.
[0031] In use, the first clamping housing 1 and one side of the multi-layer sealing member 101 can clamp and seal one waterproof bag, while the other side of the multi-layer sealing member 101 and the third clamping housing 102 can clamp and seal another waterproof bag. The additional waterproof bags allow users to place mobile phones or valuables, preventing items from rubbing against each other within the same waterproof bag, improving organization and ease of use. It is worth noting that multiple multi-layer sealing members 101 can be used to clamp and seal more waterproof bags; this embodiment does not limit this.
[0032] Secondly, sealing gaskets (which can be made of rubber) can be provided on both sides of the multi-layer sealing member 101. These gaskets effectively prevent liquid from seeping into the waterproof bag through the gaps between the first clamping shell 1 and the multi-layer sealing member 101, or between the multi-layer sealing member 101 and the third clamping shell 102. Hanging loops 1011 are also provided on the sides of the multi-layer sealing member 101. These loops allow users to easily hang the waterproof bag on backpacks, swimming rings, or other objects, or provide a hanging position when the waterproof bag needs to be dried, increasing the convenience and flexibility of the waterproof bag and making it easier for users to carry and store it in different scenarios.
[0033] In addition, multiple waterproof bags are tightly connected together by the first clamping shell 1 and the third clamping shell 102, which reduces the possibility of a single waterproof bag accidentally falling off or being lost during use, making the waterproof bags less likely to be lost and better ensuring that the waterproof bags are always with the user and ensuring the safety of the items inside the bags.
[0034] Furthermore, the first clamping housing 1, the multi-layer sealing component 101, and the third clamping housing 102 can be designed as separate units. This design allows for a wider opening in the waterproof bag when the user disassembles the first clamping housing 1 and the third clamping housing 102, making it easier for the user to place valuables into the waterproof bag, thereby further improving ease of use.
[0035] In this embodiment, positioning grooves 103 are provided on both sides of the multi-layer sealing component 101, and positioning posts 104 are provided on the side of the first clamping housing 1 and the third clamping housing 102 facing the multi-layer sealing component 101. Each positioning post 104 is slidably connected to the inner wall of the corresponding positioning groove 103. By setting the positioning posts 104 and positioning grooves 103, the alignment accuracy of the first clamping housing 1, the multi-layer sealing component 101 and the third clamping housing 102 during assembly can be ensured, avoiding poor sealing due to misalignment, thereby improving the sealing performance of the sealing assembly. In addition, the cooperation between the positioning grooves 103 and the positioning posts 104 can reduce the probability of the waterproof bag being laterally displaced due to external forces (such as water flow impact) during use to a certain extent, further ensuring the sealing performance of the sealing assembly.
[0036] Furthermore, each positioning post 104 is designed in a cylindrical shape, and the top of the positioning post 104 facing the multi-layer sealing member 101 is designed in an arc shape. The arc-shaped top positioning post 104 is easier to slide into the positioning groove 103, avoiding jamming or material wear caused by right-angle edges. This reduces the wear on the end face of the multi-layer sealing member 101 when the user assembles the first clamping housing 1 with the multi-layer sealing member 101, or the multi-layer sealing member 101 with the third clamping housing 102. This reduces the probability of increased gaps between the clamping housings due to material wear and improves the service life of the sealing assembly.
[0037] Secondly, a chamfer is provided on the top of the side of the positioning groove 103 near the positioning post 104. The chamfer forms an inlet slope, which helps the positioning post 104 to enter the positioning groove 103 more smoothly, reducing the assembly difficulty and improving the ease of operation.
[0038] In this embodiment, a first fixing post 105 is provided on both sides of the multi-layer sealing member 101, and a first clamping member 106 is fixedly connected to the side of each first fixing post 105 away from the multi-layer sealing member 101. A second fixing post 107 is provided on the side of the first clamping shell 1 and the third clamping shell 102 facing the first clamping member 106, and a second clamping member 108 is fixedly connected to the side of each second fixing post 107 close to the first clamping member 106.
[0039] It should be noted that the waterproof bag clamped in this embodiment is based on a conventional waterproof bag with a connecting protrusion. The connecting protrusion is located at the opening of the waterproof bag, and the connecting protrusion also has a connecting hole for the first fixing post and the second fixing post 107 to pass through. In use, the connecting hole should be inserted through the surface of the first fixing post 105 and the second fixing post 107, and one side of the connecting protrusion should be fixedly connected to one side of the first clamping member 106 or the second clamping member 108. The first fixing post 105 and the second fixing post 107 fix both ends of the bag sleeve, thereby preventing the first clamping shell 1, the multi-layer sealing member 101 and the third clamping shell 102 from detaching from the bag body when separated, eliminating the need for the user to reassemble the bag sleeve with each clamping shell, and improving the convenience of use. The fixed connection of one side of the connecting protrusion to one side of the first clamping member 106 or the second clamping member 108 is to prevent liquid from seeping into the waterproof bag through the gaps between them.
[0040] In this embodiment, the first clamping shell 1 and the third clamping shell 102 are detachably connected by a fixing component. The fixing component is used to tightly connect the first clamping shell 1, the multi-layer sealing member 101 and the third clamping shell 102 to prevent liquid from seeping into the waterproof bag from the gaps between them.
[0041] The fixing component includes a hook 2. Both sides of the first clamping housing 1 and the multi-layer sealing member 101 are provided with through holes 201, and each side of the through hole 201 is fixedly connected with an arc-shaped block 202. The hook 2 includes a bending part 203, a handle part 204, and a snap-fit part 205 (the bending part 203, the handle part 204, and the snap-fit part can be integrally formed to improve the overall structural strength). Both sides of the bending part 203 are provided with arc-shaped grooves 206. One side of the hook 2 is provided with an opening 207 for the arc-shaped block 202 to enter the arc-shaped groove 206. When the arc-shaped block contacts the inner wall of the arc-shaped groove 206, the center of the arc-shaped groove 206 is concentric with the center of the arc-shaped block 202. The side of the first clamping housing 1 near the through hole 201 is provided with a groove 208 that snaps into the snap-fit part 205.
[0042] When the first clamping housing 1, the multi-layer sealing member 101, and the third clamping housing 102 are assembled, the user positions the side of the hook 2 with the opening 207 towards the arc-shaped block 202, allowing the arc-shaped block 202 to enter the arc-shaped groove 206. Then, the handle 204 is rotated 90 degrees clockwise, causing the arc-shaped groove 206 to press and fix the arc-shaped blocks 202 on the first clamping housing 1 and the third clamping housing 102 together. Finally, the engaging part 205 engages with the groove 208 on the first clamping housing 1, thereby fixing the first clamping housing 1 and the third clamping housing 102. It is worth noting that when the engaging part 205 engages with the groove 208, the engaging part 205 will deform under the user's action, thus engaging with the groove 208. To prevent the engaging part 205 from breaking, it can be made of ABS plastic. ABS plastic has good plasticity and toughness, and can deform under certain conditions without breaking.
[0043] When separation is required, the user rotates the handle 204 counterclockwise by 90 degrees, causing the locking part 205 to deform and disengage from the groove 208, thereby separating the first clamping housing 1, the multi-layer sealing member 101, and the third clamping housing 102. Simultaneously, the hook 2 is also in a separated state. To prevent the hook 2 from being lost, a hanging rope can be provided on the first clamping housing 1 and connected to the hook 2 to prevent its loss.
[0044] Secondly, a receiving groove 209 for placing the handle part 204 is provided on the side of the first clamping housing 1 near the through hole 201. The groove 208 is provided at the bottom of the receiving groove 209. The receiving groove 209 allows the handle part 204 to be stored in the receiving groove 209, which saves space and prevents the handle part 204 from being exposed to the outside and being hit or misoperated. It also makes the appearance of the entire sealing assembly neater.
[0045] In addition, one side of the handle portion 204 extends to the outside of the first clamping housing 1, and the side of the handle portion 204 is inclined. The inclined side design conforms to the ergonomic principle, making it convenient for users to apply force to operate the handle portion 204 by hand, and making it easier to open and close the hook 2, thus improving the user's comfort and convenience.
[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
