These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0024] Reference Figure 1 As shown, the utility model provides a technical solution: a foldable photography backpack, comprising a backpack body 1, one end of the backpack body 1 is equipped with two shoulder straps 2, the other end of the backpack body 1 is fixedly connected with a first connecting plate 3 and a second connecting plate 4, the number of the first connecting plate 3 and the second connecting plate 4 is two, the bottom of the first connecting plate 3 and the top of the second connecting plate 4 are fixedly connected with an elastic band 5, one side of the first connecting plate 3 is fixedly connected with a first handle 6, one side of the second connecting plate 4 is fixedly connected with a second handle 13, the other side of the first connecting plate 3 is fixedly connected with a fixing plate 7, the surface of the fixing plate 7 is slidably connected with a hollow block 8, and the other side of the second connecting plate 4 is fixedly connected with a fixing block 9, by folding the first connecting plate 3 and the second connecting plate 4 and using them in conjunction with the elastic band 5, the backpack body 1 can be folded and compressed, so that the backpack body 1 can be folded together more compactly, and then by moving the hollow block 8, the interior of the hollow block 8 is sleeved with the surface of the fixing block 9, the folded backpack body 1 is fixed to prevent it from opening again.

[0025] Reference Figure 1 As shown, in the present embodiment: a slide groove 10 is provided at the top and the bottom of the fixed plate 7, and a slider 11 is fixedly connected to the top and the bottom of the inner cavity of the hollow block 8, and the performance of the slider 11 is slidably connected to the inside of the slide groove 10. By setting the slide groove 10 and the slider 11, the position of the hollow block 8 on the fixed plate 7 can be fine-tuned, so as to facilitate the user to adjust the position of the hollow block 8 according to actual needs to meet different usage requirements. At the same time, the sliding connection between the slider 11 and the slide groove 10 makes the hollow block 8 more stable during movement, and is not prone to shaking or displacement, thereby ensuring the stability and reliability of the equipment.

[0026] Reference Figure 1As shown, in the present embodiment: a return spring 12 is fixedly connected to one side of the slider 11, and one side of the return spring 12 is fixedly connected to the inside of the slide groove 10. The introduction of the return spring 12 not only enhances the stability of the slider 11 in the slide groove 10, but also can quickly return the slider 11 to its initial position through its elastic restoring force after the slider 11 is displaced by an external force.

[0027] Reference Figure 1 As shown, in this embodiment: the external shape of the fixed block 9 is consistent with the internal shape of the hollow block 8. The matching design of the fixed block 9 and the hollow block 8 not only makes the combination between the two tighter and more stable, but also improves the aesthetics of the overall structure. This design can effectively prevent the fixed block 9 from loosening or shifting inside the hollow block 8, thereby ensuring the stability and reliability of the overall structure.

[0028] Reference Figure 1 As shown, in the present embodiment: one end of the first handle 6 is fixedly connected to an extension block 14, one end of the extension block 14 is fixedly connected to a push block 15, one end of the second handle 13 is provided with a slot 20, both sides of the inner cavity of the slot 20 are provided with movable slots 16, the interior of the movable slot 16 is fixedly connected to a telescopic rod 17, one side of the telescopic rod 17 is fixedly connected to a force block 18, when the backpack body 1 is folded, the push block 15 of the first handle 6 will be inserted into the slot 20 of the second handle 13, then, by moving the force block 18, they slide inwardly under the guidance of the telescopic rod 17 until they are tightly fitted on both sides of the push block 15, and the push block 15 is fixed, so that the first handle 6 and the second handle 13 are connected as a whole, which is convenient to carry.

[0029] Reference Figure 1 As shown, in the present embodiment: one side of the force-bearing block 18 is fixedly connected with a thrust spring 19, and one side of the thrust spring 19 is fixedly connected to the inside of the movable groove 16. The setting of the thrust spring 19 enables the force-bearing block 18 to quickly return to its original position through the elastic restoring force of the thrust spring 19 after being acted upon by an external force, thereby ensuring the stability and reliability of the force-bearing block 18. At the same time, the elasticity of the thrust spring 19 ensures that the force-bearing block 18 can generate corresponding displacements when subjected to external forces of different magnitudes, and quickly reset after the external force disappears, thereby achieving precise control of the force-bearing block 18.

[0030] Reference Figure 1 As shown, in this embodiment: the shapes of both sides of the pushing block 15 and the shape of one side of the force block 18 are both arc-shaped. The arc-shaped shape makes the pushing block 15 and the force block 18 smoother when they move relative to each other. This is because the arc-shaped surface can guide the direction of movement, making the relative movement between the two smoother. At the same time, the arc-shaped surface can disperse the stress more evenly when subjected to external force.

[0031] Working principle: By folding the first connecting plate 3 and the second connecting plate 4 and using them in conjunction with the elastic band 5, the backpack body 1 can be folded and compressed so that the backpack body 1 can be folded together more compactly. Then, by moving the hollow block 8, the interior of the hollow block 8 and the surface of the fixed block 9 are sleeved to fix the folded backpack body 1 to prevent it from opening again. By setting the slide groove 10 and the slider 11, the position of the hollow block 8 on the fixed plate 7 can be fine-tuned, so that the user can adjust the position of the hollow block 8 according to actual needs to meet different usage requirements. The sliding connection between the slider 11 and the slide groove 10 makes the hollow block 8 more stable during movement, less prone to shaking or offsetting, and ensures the stability and reliability of the equipment. The introduction of the reset spring 12 not only enhances the stability of the slider 11 in the slide groove 10, but also can quickly reset the slider 11 to its initial position through its elastic restoring force after the slider 11 is displaced by external force. The matching design of the fixed block 9 and the hollow block 8 not only makes the combination between the two tighter and more stable, but also improves the aesthetics of the overall structure. This design can effectively The fixing block 9 is prevented from loosening or shifting inside the hollow block 8, thereby ensuring the stability and reliability of the overall structure. When the backpack body 1 is folded, the pushing block 15 of the first handle 6 will be inserted into the notch 20 of the second handle 13. Then, by moving the force-bearing block 18, they slide inward under the guidance of the telescopic rod 17 until they are tightly fitted on both sides of the pushing block 15 to fix the pushing block 15. In this way, the first handle 6 and the second handle 13 are connected into a whole, which is convenient for carrying. The setting of the thrust spring 19 enables the force-bearing block 18 to be able to be pushed by the thrust spring after being subjected to external force. The elastic restoring force of 19 can quickly restore it to its original position, thereby ensuring the stability and reliability of the force-bearing block 18. At the same time, the elasticity of the thrust spring 19 can ensure that the force-bearing block 18 can produce corresponding displacement when subjected to external forces of different magnitudes, and quickly reset after the external force disappears, thereby achieving precise control of the force-bearing block 18. The arc shape makes the push block 15 and the force-bearing block 18 smoother in relative motion. This is because the arc surface can guide the direction of movement, making the relative movement between the two smoother. At the same time, the arc surface can disperse the stress more evenly when subjected to external force.
