Description

Technical Field

[0001] This utility model relates to the field of cushioning structure technology, specifically a backpack cushioning structure that is easy to assemble. Background Technology

[0002] A backpack is a bag worn on the back. It comes in a variety of materials, including genuine leather, plastic, polyester, canvas, nylon, cotton, and linen. Nowadays, backpacks are usually equipped with cushioning structures to improve their performance.

[0003] For example, the utility model patent with authorization announcement number CN214230253U discloses a cushioning structure for a sports backpack. This structure has the advantage of cushioning and shock absorption at the bottom of the backpack, making it convenient for users and improving the practicality of the sports backpack.

[0004] However, in actual use, this structure is directly installed inside the backpack, making it inconvenient to disassemble and assemble. When the shock absorption mechanism is damaged, it is inconvenient to replace it, which reduces the backpack's cushioning performance and fails to meet the usage requirements well. Summary of the Invention

[0005] The purpose of this invention is to provide a backpack cushioning structure that is easy to assemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0008] As a preferred embodiment, the snap-fit ​​assembly includes connecting rods extending from both ends of the elastic band, and the ends of the connecting rods are also provided with connecting protrusions. Both the upper and lower ends of the connecting seat are provided with connecting slots, and the connecting slots are connected to each other through a connecting groove. A connecting slot is also provided at a corresponding position on the connecting seat. The connecting rods are inserted into the connecting grooves, and the connecting protrusions are snapped into the connecting slots.

[0009] As a preferred embodiment, both the connecting rod and the connecting slot are made of rubber material.

[0010] As a preferred embodiment, the guide frame is U-shaped.

[0011] As a preferred embodiment, the guide frame has guide grooves on opposite sides, and guide sliders are provided at both ends of the guide slide corresponding to the positions of the guide grooves, and the guide sliders are slidably installed in the guide grooves.

[0012] As a preferred embodiment, the anti-detachment mechanism includes anti-detachment grooves at both ends of the guide frame. An anti-detachment retaining ring is also provided on the side of the anti-detachment groove near the guide groove. An anti-detachment mounting groove is also provided on the guide frame at the position corresponding to the anti-detachment groove. An anti-detachment end cap is installed in the anti-detachment mounting groove. An anti-detachment slider is slidably installed in the anti-detachment groove. An anti-detachment insert is also installed on the side of the anti-detachment slider near the anti-detachment retaining ring. The anti-detachment insert extends into the anti-detachment groove. An anti-detachment spring is installed between the anti-detachment end cap and the anti-detachment slider.

[0013] As a preferred embodiment, the upper end of the anti-detachment plug is also provided with an anti-detachment chamfer.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-6 A backpack cushioning structure for easy assembly includes: a cushioning plate 1 detachably mounted on the backpack; a guide frame 2 mounted on the cushioning plate 1; the guide frame 2 being U-shaped; a guide slide 21 slidably mounted inside the guide frame 2; connecting seats 4 mounted on both the guide slide 21 and the guide frame 2; an elastic band 3 clamped between a pair of connecting seats 4 via a snap-fit ​​assembly; a cushioning shell 11 detachably mounted on the cushioning plate 1; and an anti-detachment mechanism 5, disposed on the guide frame 2, for preventing the guide slide 21 from detaching from the guide frame 2. In this embodiment, the backpack straps 12 are fixed to the connecting seats 4 above.

[0024] The working principle of this utility model is as follows: the elastic band 3 is installed by the snap-fit ​​component, which is convenient for disassembly and replacement, ensuring the cushioning performance of the backpack. The detachable buffer shell 11 and buffer plate 1 are easy to disassemble and install, further improving the convenience of replacing the elastic band 3, thereby better meeting the usage needs. The anti-slip mechanism 5 can effectively prevent the guide slide 21 from slipping, ensuring the stability of the cushioning performance.

[0025] As a further embodiment, the snap-fit ​​assembly includes connecting rods 31 extending from both ends of the elastic band 3. The ends of the connecting rods 31 are also provided with connecting protrusions 32. The upper and lower ends of the connecting seat 4 are provided with connecting slots 43, which are connected to each other through a connecting groove 41. The corresponding positions on the connecting seat 4 are also provided with connecting slots 42. The connecting rods 31 are inserted into the connecting grooves 41, and the connecting protrusions 32 are snapped into the connecting slots 43. In this embodiment, both the connecting rods 31 and the connecting slots 43 are made of rubber material.

[0026] During installation, align the connecting rods 31 at both ends of the elastic band with the corresponding connecting slots 42, and then press the connecting rods 31 to deform them, making it easier for them to enter the connecting slots 41. Once the connecting rods 31 at both ends of the band are inserted into the corresponding connecting slots 41, the connection is complete. When the upper connecting seat 4 moves upward, the connecting protrusions 32 at the ends of the connecting rods 31 engage with the connecting slots 43, effectively preventing the connecting rods 31 from slipping out of the connecting slots 41.

[0027] To improve the stability of the guide slide 21, guide grooves 23 are provided on opposite sides of the guide frame 2, and guide sliders 22 are provided at both ends of the guide slide 21 at positions corresponding to the guide grooves 23. The guide sliders 22 are slidably installed in the guide grooves 23.

[0028] As a further embodiment, the anti-detachment mechanism 5 includes anti-detachment grooves 55 at both ends of the guide frame 2. An anti-detachment retaining ring 57 is also provided on the side of the anti-detachment groove 55 near the guide groove 23. An anti-detachment mounting groove 56 is also provided on the guide frame 2 corresponding to the position of the anti-detachment groove 55. An anti-detachment end cap 53 is installed in the anti-detachment mounting groove 56. An anti-detachment slider 51 is slidably installed in the anti-detachment groove 55. An anti-detachment insert 54 is also installed on the side of the anti-detachment slider 51 near the anti-detachment retaining ring 57. The anti-detachment insert 54 extends into the anti-detachment groove 55. An anti-detachment spring 52 is installed between the anti-detachment end cap 53 and the anti-detachment slider 51. An anti-detachment chamfer 541 is also provided on the upper end of the anti-detachment insert 54. The anti-detachment chamfer 541 facilitates the installation of the guide slide 21.

[0029] The working principle of the anti-detachment mechanism 5 is as follows: During installation, the guide sliders 22 at both ends of the guide slide block 21 are aligned with the guide groove 23. Then, the guide slide block 21 is pushed down, so that the guide sliders 22 squeeze the anti-detachment block 54, thereby pushing the anti-detachment block 54 to move and retract into the anti-detachment groove 55. At this time, the anti-detachment spring 52 is compressed. When the guide slider 22 has moved to the bottom of the anti-detachment block 54, the anti-detachment spring 52 is reset and pushes the anti-detachment block 54 into the guide groove 23, which can block the guide slider 22 and prevent the guide slider 22 from driving the guide slide block 21 to detach from the guide groove 23, thus ensuring the normal operation of the elastic band 3.
