DETAILED DESCRIPTION
[0035] The following is combined with Figure 1-5 This application is described in further detail.
[0036] The present application embodiment discloses an anti-theft travel backpack. Figure 1 and Figure 2 The anti-theft travel backpack includes a bag body 1, a shoulder strap 2, a zipper 3, a limiting component 4 and a traction rope 5.
[0037] Reference Figure 1 The bag body 1 is formed by sewing a plurality of bag sheets 11, the bag body 1 is provided with a receiving cavity 12 for receiving articles, and the bag sheet 11 is provided with a bag opening 13. Both ends of the shoulder strap 2 are fixedly connected to the gasket, and a space for the wearer to wear is provided between the shoulder strap 2 and the bag body 1.
[0038] Reference Figure 1 The zipper 3 is arranged at the bag opening 13, and the zipper 3 is used to open and close the bag opening 13. Specifically, the zipper 3 includes a chain 31 and a pull head 32 arranged opposite to each other. The chain 31 is fixedly connected to the bag sheet 11, and the pull head 32 is slidably connected to the chain 31, so that the bag opening 13 is opened or closed by pulling the pull head 32.
[0039] Reference Figure 1In this embodiment, the two opposite ends of the zipper 3 are named as the open end 33 and the closed end 34. When the slider 32 moves from the closed end 34 to the open end 33, the two oppositely arranged chains 31 engage with each other, thereby closing the bag opening 13 of the bag body 1. When the slider 32 moves from the open end 33 to the closed end 34, the two oppositely arranged chains 31 separate from each other, thereby opening the bag opening 13 of the bag body 1, so that the accommodating cavity 12 is connected to the outside.
[0040] Reference Figure 2 The slider 32 is also provided with a second limit block 6, which is disposed in the accommodating cavity 12. The first limit block 43 can be made of materials such as silicone and rubber; the first limit block 43 and the slider 32 can be fixedly connected by bonding, plugging, etc.; thus, the slider 32 can drive the second limit block 6 to move horizontally.
[0041] Reference Figure 2 The limiting component 4 is arranged in the container cavity, the limiting component 4 is fixedly connected to the bag sheet 11, and the limiting component 4 is arranged on the side of the open tail section away from the closed tail end 34.
[0042] Reference Figure 2 The limiting assembly 4 includes a bottom plate 41, a limiting rod 42, a first limiting block 43 and a reset member. The bottom plate 41 is fixedly connected to the bag sheet 11, and the bottom plate 41 and the bag sheet 11 can be fixedly placed by means of rivet connection, bonding, etc. One end of the limiting rod 42 is hinged to the bottom plate 41, and the other end of the limiting rod 42 is fixedly connected to the first limiting block 43. The first limiting block 43 is arranged on the side of the limiting rod 42 close to the zipper 3. Under normal circumstances, the first limiting block 43 is arranged on the moving path of the slider 32, and the first limiting block 43 abuts against the slider 32 and the second limiting block 6 to limit the slider 32 from moving toward the closed tail section. At the same time, the side of the first limiting block 43 away from the limiting rod 42 is set as a guide surface 431, and the distance from the guide surface 431 to the zipper 3 increases along the direction away from the limiting rod 42.
[0043] Reference Figure 2 and Figure 3 When the slider 32 moves from the closed end 34 of the zipper 3 to the open end 33, the slider 32 abuts against the guide surface 431 and slides, so that the slider 32 falls to the side of the first limit block 43 close to the open end 33. That is, the first limit block 43 is used to limit the second limit block 6 from moving toward the closed end 34, thereby limiting the movement of the slider 32.
[0044] Reference Figure 2The reset member is disposed between the bottom plate 41 and the limiting rod 42, and the reset member is used to force the limiting rod 42 to rotate toward the zipper 3, so that the first limiting block 43 at the end of the limiting rod 42 is located on the moving path of the slider 32. In this embodiment, the reset member is a magnet 44, and the limiting rod 42 is made of iron; the reset member is fixed on the bottom plate 41, and the magnet 44 is used to absorb the limiting rod 42.
[0045] Reference Figure 3 When the user closes the bag opening 13 of the bag body 1 through the zipper 3, the first limit block 43 of the limit assembly 4 is arranged on the moving path of the slider 32, thereby limiting the slider 32 from moving toward the closing end of the zipper 3, so that the bag opening 13 of the travel backpack remains closed. This improves the anti-theft performance of the travel backpack, that is, reduces the occurrence of other people opening the bag opening 13 of the travel backpack through the zipper 3, and reduces the occurrence of theft of property in the bag body 1.
[0046] Reference Figure 2 The bag sheet 11 is provided with a fixing hole 111 for the traction rope 5 to pass through, and the travel backpack also includes a metal ring 7, which is fixedly connected to the side wall of the fixing hole 111 to reduce the structural loss of the bag sheet 11 caused by the side wall of the hole.
[0047] Reference Figure 1 and Figure 4 In this embodiment, the traction rope 5 includes a first component 51 and a second component 52, and the first component 51 and the second component 52 are fixedly connected at their ends; the connection method of the first component 51 and the second component 52 can be binding or bonding. The first component 51 is bonded to the limiting rod 42, and one end of the first component 51 and the limiting rod 42 bonded and fixed is the first end 53 of the traction rope 5. The second component 52 extends to the outside of the bag body 1, and the second component 52 is sewn to the bag body 1. In this embodiment, the cross-sectional area of the first component 51 is smaller than the cross-sectional area of the second component 52. The cross-sectional area of the first component 51 is smaller, so it is convenient for the first component 51 to be bonded and connected to the limiting rod 42; the cross-sectional area of the second component 52 is larger, so it is convenient for the user to pinch the traction rope 5.
[0048] Reference Figure 1 and Figure 4 When the user needs to open the backpack, the user pinches the traction rope 5 with one hand and pulls the traction rope 5 away from the bag head; thereby, the traction rope 5 pulls the limiting rod 42 to move away from the bag body 1, so that the first limiting member turns away from the moving path of the slider 32, that is, the limiting effect of the limiting component 4 on the slider 32 is released, and the user can move the slider 32 from the open tail end 33 to the closed tail end 34 to open the bag opening 13.
[0049] Example 2
[0050] The difference between this embodiment 2 and embodiment 1 is that:
[0051] Reference Figure 5 The reset member is a torsion spring 45, which includes a coil segment 452, a first straight portion 451 and a second straight portion 453 arranged on both sides of the coil segment 452; the coil portion, the first straight portion 451 and the second straight portion 453 are formed by bending a piece of iron wire. At the same time, the bottom plate 41 is provided with a plug-in column for the coil portion to be plugged and fixed, the first straight portion 451 is fixedly abutted against the bottom plate 41, and the second straight portion 453 is fixedly abutted against the limiting rod 42. The torsion spring 45 exerts force on the bottom plate 41 and the limiting rod 42, thereby realizing the limiting effect of the limiting assembly 4 on the pull head 32.
[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
