[0031] Example 2
[0032] Reference Figure 1-7This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, a support seat 18 is fixedly connected to one side of the base 1, and the bottom end of the slide rod 19 is fixedly connected to the top end of the support seat 18. The slide rod 19 is slidably sleeved with a slide sleeve 20. A groove 21 is provided inside the slide rod 19. One end of the inner wall of the groove 21 is fixedly connected to one end of the second spring 22, and the other end of the second spring 22 is fixedly connected to one end of the locking block 23. The other end of the locking block 23 is locked with a through hole 24. The through holes 24 are evenly distributed on the slide sleeve 20. A handle 25 is fixedly connected to the top end of the slide sleeve 20. In use, according to the user's height and usage habits, the locking block 23 is pressed, and the locking block 23 drives the second spring 22 to retract. The locking block 23 is not locked with the through hole 24 when pressed. Then, the slide sleeve 20 is moved along the slide rod 19. After moving to a suitable position, the locking block 23 is locked with the corresponding through hole 24. By designing an adjustable slide rod 19, the length of the slide rod 19 can be adjusted according to the user's height, improving the versatility of the device.
[0033] The sliding sleeve 20 is fixedly connected to the tape collection box 26 on the side near the stacked bags 5. One end of the inner wall of the tape collection box 26 is rotatably connected to one end of the rotating shaft 30. The other end of the rotating shaft 30 rotates through the tape collection box 26 and is fixedly connected to the crank handle 31. When in use, the crank handle 31 is turned, and the crank handle 31 drives the rotating shaft 30 to rotate and wind up the strap 27. By turning the crank handle 31, the length of the exposed strap 27 can be changed, so that the device can be adjusted in time according to the number and height of the stacked bags 5, ensuring the stability and applicability of the device.
[0034] One end of the strap 27 is fixedly installed on the rotating shaft 30. The other end of the strap 27 slides through the tape collection box 26 and is fixedly connected to one end of the buckle 28. The other end of the buckle 28 is snapped into the female buckle 29. The female buckle 29 is fixedly installed on one side of the base 1. When in use, pull the buckle 28. The buckle 28 drives the strap 27 to be taken out from the tape collection box 26 and moves along the surface of the stacked bag 5 and the bottom bag 3, and finally snaps into the female buckle 29 to ensure the stability of the bottom bag 3 and the stacked bag 5.
[0035] A cavity 32 is provided above the opening end of the collection box 26. One end of a third spring 33 is fixedly connected to both sides of the inner wall of the top of the cavity 32. The other end of the third spring 33 is fixedly connected to the top of the limiting block 34. The bottom end of the limiting block 34 slides through the cavity 32 and is fixedly connected to a pointed cone block 35. The pointed cone block 35 abuts against the strap 27 to prevent the strap 27 from moving and to ensure the structural stability of the device.
[0036] The top of the limiting block 34 is fixedly connected to one end of the connecting rod 36, and the other end of the connecting rod 36 slides through the cavity 32 and is fixedly connected to the handle 37. By lifting the handle 37, the movement of the limiting block 34 is controlled, further controlling the contact between the pointed cone block 35 and the strap 27, adjusting the exposed length of the strap 27, and improving the versatility of the device.
[0037] The base 1 is fixedly connected to four omnidirectional wheels 38 at its bottom. The omnidirectional wheels 38 allow the entire device to be moved, eliminating the need to carry a travel bag, reducing the user's physical exertion, and improving the convenience and comfort of using the device.
[0038] The outer surface of the pressing block 17 has vertical stripes. The surface texture design increases friction, making it less slippery even when the palm is sweaty, thus improving the stability of use.
[0039] The handle 25 is equipped with sponge pads all around its interior. The sponge is embedded in the handle 25 to reduce the impact of road vibration on the hands when pushing, making it suitable for long-term use and improving user comfort.
[0040] The strap 27 is made of nylon braided tape. Nylon (polyamide fiber) itself has high tensile strength, and the braided tape further enhances toughness and improves stability during use through its interlaced warp and weft structure.
[0041] In use, the bottom bag 3 is placed directly on the base 1, and the moving block 7 is engaged and fixed with the slot 9. When disassembling, by pressing the pressing block 17, the pressing block 17 drives the second rack 14 to move along the slide groove 16. The second rack 14 meshes with the gear 13 to rotate. The gear 13 rotates and further meshes with the first rack 11 to move. The first rack 11 drives the moving block 7 to move along the cavity 6 through the connecting column 10. The moving block 7 moves out of the slot 9. Then the support base 2 can be removed from the base 1, and the bottom bag 3 can be removed. By designing the bottom bag 3 and the base 1 to be detachable, and by using a snap-fit connection, the ease of installation is ensured, and the pressing block 17 enables quick disassembly. The operation is simple and does not require tools, thus improving the convenience of operation.
[0042] When traveling, users can freely decide the number of layers of the travel bag according to the amount of items they actually carry. For short trips with fewer items, use the bottom bag 3, while for long trips or when shopping a lot, stack 2-3 layers of the stacked bags 5. When in use, the top of the bottom bag 3 is connected to the stacked bags 5 via the zipper 4. There is no need to carry multiple separate bags, which makes efficient use of space and allows different types of items to be classified and placed in different layers of travel bags for easy access and organization.
[0043] Next, to ensure the stability of the bottom bag 3 and the stacked bag 5, pull the handle 37, then pull the buckle 28. The buckle 28 drives the strap 27 to be taken out from the tape box 26 and move along the surface of the stacked bag 5 and the bottom bag 3, finally engaging with the female buckle 29. Then, release the handle 37, and under the action of the third spring 33, push the limiting block 34 to move. The limiting block 34 drives the pointed cone block 35 to move synchronously and abut against the strap 27, preventing the strap 27 from moving.
[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
