Description

Technical Field

[0001] This utility model relates to the field of anti-theft backpack technology, and in particular to a wear-resistant and waterproof anti-theft backpack. Background Technology

[0002] Backpacks are an indispensable part of people's lives, used to carry valuables and facilitate travel. With social development and the continuous improvement of people's consumption level, people's requirements for backpacks are becoming more and more diverse. One of them is the anti-theft effect. When traveling, personal valuables are carried in the backpack, and the zipper is exposed. It is easy for people other than the backpack user to open the zipper. Moreover, when the backpack is worn on the back, it is in a blind spot, and it is not easy for the backpack user to notice when someone opens the zipper, which can easily lead to the theft of items inside the backpack.

[0003] For example, Chinese Patent Publication No. CN214047897U describes an anti-theft backpack, which includes a backpack body with an opening. The edge of the opening is provided with a zipper strap, and two zipper heads are engaged on the zipper strap. Each zipper head has a support seat rotatably connected to its upper surface, and a connecting rod is hinged to the upper surface of each support seat. The backpack is also provided with a locking component to fix the position of the connecting rod when the two zipper heads abut against each other.

[0004] However, in the above solution, although the device can lock and fix the two zipper heads when in use, the zipper heads and locking components are exposed, making the locking components of the zipper heads easy to open or be damaged, thus causing the items in the backpack to be lost. Utility Model Content

[0005] This invention provides a wear-resistant and waterproof anti-theft backpack to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A wear-resistant and waterproof anti-theft backpack includes a backpack with a zipper on the top outer ring and two zipper pulls on the zipper surface. A protective strap is fixedly connected to the top of the backpack, and a fixing block is fixedly connected to the side wall of the protective strap. Two slots are formed on the side wall of the fixing block, and one end of each of the two zipper pulls is movably connected to the two slots. Each side wall of each zipper pull has a limit groove, and each side wall of each slot has a sliding groove. A spring is fixedly connected to the side wall of each sliding groove, and an L-shaped push plate is fixedly connected to one end of each of the two springs. One end of each L-shaped push plate is slidably connected to the two sliding grooves, and one end of each L-shaped push plate passes through the side wall of the fixing block and is slidably connected to the fixing block. The two ends of each L-shaped push plate are located on both sides of the fixing block, and a limit rod is fixedly connected to the side wall of each L-shaped push plate. The two limit rods are located in the two slots and pass through the two limit grooves.

[0008] As a further improvement to this technical solution: the backpack is made of wear-resistant material and has a waterproof coating on its surface.

[0009] As a further improvement to this technical solution: each of the two fixed blocks is fixedly connected to a push block at one end, and the surfaces of the two push blocks are provided with anti-slip textures.

[0010] As a further improvement to this technical solution: the backpack has two shoulder straps fixedly connected to its side wall.

[0011] As a further improvement to this technical solution: the side wall of the backpack is fixedly connected with a hook and loop fastener, and one end of the protective strap is fixedly connected with a hook and loop fastener, and the hook and loop fastener are bonded together.

[0012] As a further improvement to this technical solution: one end of each of the two limiting rods is set in a hemispherical shape.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: After placing items inside the backpack, the backpack is sealed by pulling the two zipper pulls, positioning them at the top. Then, the two push blocks are pressed simultaneously. These push blocks, through L-shaped push plates, compress two springs, causing them to be under stress. The two L-shaped push plates simultaneously move two limiting rods, allowing them to enter the two sliding grooves. This allows the two zipper pulls to be placed into the two locking slots. Releasing the two push blocks causes the two springs to automatically reset the two L-shaped push plates, which in turn reset the two limiting rods, allowing them to enter the two limiting grooves. This device can limit and fix the two zipper pulls, preventing them from moving. Then, the protective strap is placed on top of the fixing block and attached to the back of the backpack using Velcro with both the rough and barbed sides. This ensures the protective strap fits snugly against the back of the user. At this point, the two limiting rods can slide within the two limiting grooves due to the rotation of the protective strap. This not only limits and fixes the two zipper pulls but also conceals them, improving their concealment. Furthermore, with one end of the protective strap attached to the user's back, it prevents criminals from easily opening the strap and thus preventing them from unlocking the zipper and opening the backpack, thereby improving the security of the items inside.

[0022] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described in more detail below by way of example with reference to the accompanying drawings. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.

[0023] For examples, please refer to Figure 1-4This utility model provides a technical solution: a wear-resistant and waterproof anti-theft backpack, including a backpack 1. A zipper 2 is provided on the outer top ring of the backpack 1, and two zipper pulls 7 are provided on the surface of the zipper 2. A protective strap 4 is fixedly connected to the top of the backpack 1. A fixing block 8 is fixedly connected to the side wall of the protective strap 4. Two slots 9 are formed on the side wall of the fixing block 8. One end of each zipper pull 7 is movably connected to one of the two slots 9. A limit groove 12 is formed on the side wall of each of the two zipper pulls 7. A sliding groove 15 is formed on the side wall of each of the two slots 9. A spring 1 is fixedly connected to the side wall of each of the two sliding grooves 15. 3. One end of each of the two springs 13 is fixedly connected to an L-shaped push plate 10. One end of each of the two L-shaped push plates 10 is slidably connected to two sliding grooves 15. One end of each of the two L-shaped push plates 10 passes through the side wall of the fixed block 8 and is slidably connected to the fixed block 8. The two ends of each of the two L-shaped push plates 10 are located on both sides of the fixed block 8. The side walls of each of the two L-shaped push plates 10 are fixedly connected to limit rods 14. The two limit rods 14 are located in two slots 9. The two limit rods 14 pass through two limit grooves 12. One end of each of the two limit rods 14 is hemispherical.

[0024] Please see Figure 2-4 Each of the two fixed blocks 8 has a push block 11 fixedly connected to one end, and the surfaces of the two push blocks 11 are provided with anti-slip texture.

[0025] Please see Figure 1-2 The backpack 1 has a hook and loop fastener 3 fixedly connected to the side wall, and the protective strap 4 has a hook and loop fastener 6 fixedly connected to one end of the side wall. The hook and loop fastener 3 and the hook and loop fastener 6 are bonded together.

[0026] Specifically, after placing the items inside the backpack 1, the backpack 1 is sealed by pulling the two zipper pulls 7, positioning them at the top. Then, the two push blocks 11 are pressed simultaneously. These push blocks 11, through the L-shaped push plates 10, compress the two springs 13, putting them under stress. The two L-shaped push plates 10 simultaneously move the two limiting rods 14, causing them to enter the two sliding grooves 15. This allows the two zipper pulls 7 to be inserted into the two locking slots 9. Releasing the two push blocks 11 causes the two springs 13 to automatically reset the two L-shaped push plates 10, which in turn reset the two limiting rods 14, placing them into the two limiting grooves 12. This allows the two zipper pulls 7 to be fixed in place, preventing them from moving. Then, the protective strap 4 is placed on top of the fixing block 8 and attached to the back of the backpack 1 via the hook and loop side 6 and the hook and loop side 3, so that the protective strap 4 is in close contact with the back of the user. At this time, the two limiting rods 14 can slide within the two limiting grooves 12 due to the rotation of the protective strap 4. This not only fixes the two zipper pulls 7 in place, but also covers them, improving their concealment. Furthermore, with one end of the protective strap 4 attached to the back of the user, it is difficult for criminals to open the protective strap 4, thus preventing them from releasing the two zipper pulls 7 and opening the zipper 2, thereby improving the security of the items inside the backpack 1.

[0027] Please see Figure 1-2 Backpack 1 is made of wear-resistant material and has a waterproof coating on its surface to improve its wear resistance and waterproof performance.

[0028] Please see Figure 1-2 Two shoulder straps 5 are fixedly connected to the side wall of backpack 1 for carrying backpack 1 on the back.

[0029] The working principle of this utility model is as follows: After placing the item inside the backpack 1, the backpack 1 is sealed by pulling the two zipper pulls 7, so that the two zipper pulls 7 are located at the top of the backpack 1. Then, the two push blocks 11 are pressed simultaneously. The two push blocks 11 compress the two springs 13 through the L-shaped push plates 10, so that the two springs 13 are under force. The two L-shaped push plates 10 simultaneously drive the two limiting rods 14 to move, so that the two limiting rods 14 enter the two sliding grooves 15, and the two zipper pulls 7 can be placed into the two slots 9. Then, the two push blocks 11 are released, and the two springs 13 will drive the two L-shaped push plates 10 to automatically reset. The two L-shaped push plates 10 drive the two limiting rods 14 to reset, so that the two limiting rods 14 enter the two limiting grooves. Within 12, the two zipper pulls 7 can be limited and fixed, preventing them from moving. Then, the protective strap 4 is placed on top of the fixing block 8 and attached to the back of the backpack 1 through the hook and loop side 6 and the hook and loop bar side 3, so that the protective strap 4 is close to the back of the person. At this time, the two limiting rods 14 can slide within the two limiting grooves 12 due to the rotation of the protective strap 4. This not only limits and fixes the two zipper pulls 7, but also covers them, improving their concealment. Furthermore, one end of the protective strap 4 is attached to the back of the person, making it difficult for criminals to open the protective strap 4, thus preventing them from releasing the fixation of the two zipper pulls 7 and opening the zipper 2, thereby improving the security of the items inside the backpack 1.
