Description

Technical Field

[0001] This utility model belongs to the field of backpack technology, specifically relating to a modular communication backpack. Background Technology

[0002] Traditional communication backpacks have significant design limitations: their volume is relatively fixed, making it difficult to flexibly adjust to different usage scenarios. For example, for short daily trips, users may only need basic communication functions and a small amount of storage space, but traditional backpacks, due to their fixed functional integration, are relatively large, placing an unnecessary burden on users. On the other hand, for long-distance outdoor adventures or professional emergency rescue missions, users may need to carry more communication auxiliary equipment, backup power supplies, or other specialized equipment, but traditional backpacks cannot provide sufficient expansion space to meet these needs. Therefore, we have made improvements by proposing a modular communication backpack. Utility Model Content

Detailed Implementation

[0023] As attached Figures 1-6 As shown, this utility model includes a main backpack 1, with a first expansion pack 2 detachably mounted on one side of the main backpack 1. By equipping the main backpack 1 with the detachable first expansion pack 2, users can freely choose whether to install the first expansion pack 2 according to the actual usage scenario. During daily short trips, only the main backpack 1 needs to be carried, reducing the load and improving travel convenience. In scenarios where additional functions or storage space are required, the first expansion pack 2 can be installed to meet diverse needs, enabling the backpack to easily adapt to various complex and changing usage environments, thus improving the practicality and versatility of the backpack.

[0024] Several connectors are provided between the first expansion pack 2 and the main backpack 1. The connectors include a first connecting strap 301 fixedly connected to the first expansion pack 2, a first connecting ring 3 connected to the first connecting strap 301, and a second connecting strap 4 sleeved on the outer surface of the first connecting ring 3. One end of the second connecting strap 4 is fixedly connected to the main backpack 1, and the two ends of the second connecting strap 4 are connected by Velcro. The two ends of the first connecting strap 301 are fixedly connected to the first expansion pack 2. After the two ends of the second connecting strap 4 are connected by Velcro, the second connecting strap 4 can be connected to the first connecting ring 3. After the Velcro at both ends of the second connecting strap 4 is unfastened, the first connecting ring 3 and the second connecting strap 4 can be separated.

[0025] Furthermore, both the main backpack 1 and the first expansion pack 2 have a first opening at the top, and a zipper 8 is installed at the first opening. The zipper 8 is used to control the opening and closing of the first opening. The zipper 8 is convenient and quick to open and close, and can also close the first opening to ensure the safety of the items.

[0026] Furthermore, the sides of the first expansion pack 2 and the main backpack 1 that are close to each other are also connected by Velcro. This arrangement can improve the stability of the connection between the first expansion pack 2 and the main backpack 1, because the adhesiveness of the Velcro can provide additional connection force, so that the first expansion pack 2 and the main backpack 1 fit together and remain relatively fixed during user activities, thus improving the user experience.

[0027] Furthermore, the main backpack 1 has side pockets 5 on both sides. The side pockets 5 are used to install the second expansion pack 6. After the second expansion pack 6 is removed, the side pockets 5 can also be used to temporarily place items.

[0028] Furthermore, a third connecting strap 7 is installed on the side of the main backpack 1 above the side pocket 5. The third connecting strap 7 is connected to a third connecting ring 701, which can hang items to make full use of the side space and increase the variety of items that can be carried.

[0029] Furthermore, a second expansion pack 6 is inserted into the side pocket 5. The second expansion pack 6 has a second opening 601 and is connected to a baffle 602 for sealing the second opening 601. The baffle 602 is also connected to the second expansion pack 6 by Velcro. The second expansion pack 6 provides additional storage space, and the Velcro-connected baffle 602 can effectively seal the second opening 601, reduce the risk of items falling out, and ensure the safety of items.

[0030] Furthermore, a second connecting ring 604 is installed on the top of the second expansion pack 6. A spring clip 603 is connected to the second connecting ring 604, and the spring clip 603 is engaged with the third connecting ring 701. The spring clip 603 and the third connecting ring 701 cooperate with each other to restrain the second expansion pack 6 and reduce the possibility of the second expansion pack 6 falling.

[0031] Furthermore, the bottom of the main backpack 1 is provided with a bottom isolation pad 103. The top of the bottom isolation pad 103 is connected to the top of the main backpack 1 by Velcro. The bottom isolation pad 103 can be made of wear-resistant material, such as rubber. The bottom isolation pad 103 can protect the bottom of the main backpack 1. The main backpack 1 and the bottom isolation pad 103 are connected by Velcro, which makes it easy to replace the bottom isolation pad 103.

[0032] Furthermore, a pad 102 is provided on the side of the main backpack 1 away from the first extension bag 2. The pad 102 is connected to the main backpack 1 by Velcro. The pad 102 is made of 3D mesh fabric, which can improve the breathability of the user's back during use. The Velcro connection makes it easy to remove for cleaning and replacement.

[0033] Furthermore, a shoulder strap 104 is provided between the main backpack 1 and the side away from the first extension bag 2. The shoulder strap 104 is a basic carrying component of the backpack, enabling the user to carry the backpack by carrying it on both shoulders.

[0034] It should be noted that hook and loop fasteners are divided into female hook and loop fasteners and female hook and loop fasteners. The above-mentioned "connection via hook and loop fasteners" refers to the fact that the two connecting surfaces are respectively equipped with female hook and loop fasteners and female hook and loop fasteners, and the female hook and loop fasteners are connected. For example, the top of the bottom isolation pad 103 and the bottom of the main backpack 1 are respectively equipped with female hook and loop fasteners and female hook and loop fasteners.

[0035] When using the main backpack 1, if only the main backpack 1 is used, unconnect the spring buckle 603 to the third connecting ring 701, pull the second expansion pack 6 upwards to remove it from the side pocket 5, and then untie the second connecting strap 4 to remove the first expansion pack 2. If the first expansion pack 2 and the second expansion pack 6 need to be installed, insert the second expansion pack 6 into the side pocket 5, then fasten the spring buckle 603 to the third connecting ring 701 together, connect the first expansion pack 2 to the main backpack 1 with Velcro, and then pass one end of the second connecting strap 4 through the first connecting ring 3 and connect it to the other end with Velcro.
