[0002] Conferences and exhibitions often require moving and setting up exhibition areas as well as transporting exhibition goods, so a cargo transport cart is an indispensable tool.

[0003] However, existing transfer carts have limitations. They cannot be adjusted in height to meet specific needs. When handling taller items or when palletizing and transferring, existing carts are unable to accommodate them, limiting their scope of use. This can cause inconvenience and frustration for exhibition staff. Additional tools or equipment are required to handle taller items, increasing complexity and cost. Furthermore, the inability to adjust the height of a cart can limit the stacking methods and quantities of goods, impacting transfer efficiency and space utilization. Utility Model Content

[0021] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a transfer cart for conference and exhibition services, including a cart 1, the surface of the cart 1 is provided with a connecting component 4 that can increase the height and a limiting component 5 to prevent accidental falling off, the connecting component 4 includes: a fence 40, the fence 40 is arranged above the cart 1, the surface of the fence 40 is fixed with a fixing plate 41, the bottom of the fixing plate 41 is fixed with a fixing column 42, the surface of the fixing column 42 is provided with a card slot 43, the connecting component 4 also includes a fixing block 44, the fixing block 44 is fixed to the surface of the cart 1, and the fixing The top of the block 44 is provided with a mounting groove 45, the interior of the fixed block 44 is provided with a cavity 46, the inner wall of the cavity 46 is rotatably connected to a circular plate 47, the surface of the circular plate 47 is provided with a through hole 48, the inner wall of the through hole 48 is in contact with a short rod 49, the surface of the short rod 49 is fixed with a moving block 400, the moving block 400 is slidably connected to the inner wall of the cavity 46, the surface of the moving block 400 is fixed with a card block 402, the end of the card block 402 away from the moving block 400 passes through the mounting groove 45, the card block 402 is slidably connected to the fixed block 44, and the moving block 400 is provided with There are four groups, and the four groups of moving blocks 400 are all arranged in a circular array with the center of the cavity 46 as the axis center. A spring 401 is fixed between the four groups of moving blocks 400. A fixed rod 403 is fixed on the surface of one of the four groups of moving blocks 400. The end of the fixed rod 403 away from the moving block 400 passes through the fixed block 44, and the fixed rod 403 is slidably connected to the fixed block 44. A pull plate 404 is fixed on the end of the fixed rod 403 away from the fixed block 44. The surface of the end of the card block 402 away from the moving block 400 is set as an inclined surface, the through hole 48 is set as an arc, and the fixed column 42 is inserted into the fixed column 42. When the movable block 400 is inserted into the installation groove 45, the surface of the fixed column 42 contacts the inclined surface of the card block 402, and the card block 402 drives the movable block 400 to move away from the fixed column 42. Through the short rod 49, the circular plate 47, the through hole 48, and the spring 401, the card block 402 enters the card slot 43, so that the card block 402 and the card slot 43 are limited to each other. At this time, the enclosure 40 and the cart 1 are limited, which can increase the height of the cart 1, facilitate the stacking and transportation of goods, and improve the use efficiency. Pulling the pull plate 404 can drive the fixed rod 403, the movable block 400, and the card block 402 to disengage from the card slot 43.

[0022] The limiting assembly 5 includes a fixing ring 50, which is fixed to the surface of the cart 1. A rubber strip 1 51 is fixed to the inner side of the fixing ring 50. A rotating rod 52 is connected to the surface of the cart 1 for rotation. A rubber strip 2 53 is fixed to the surface of the rotating rod 52. A limiting block 1 55 and a limiting block 2 56 are fixed to the surface of the rotating rod 52. A limiting hole 54 is provided on the surface of the pull plate 404. When the rotating rod 52 is reversed, the positions of the limiting blocks 1 55 and 2 56 are staggered with the positions of the limiting holes 54. The surface of the limiting block 1 55 contacts the surface of the pull plate 404, preventing the pull plate 404 from being pulled, thereby preventing the pull plate 404 from being accidentally pulled and causing the blocking block 402 to fall out of the slot 43. The bottom of the cart 1 is equipped with rollers 2, and the surface of the cart 1 is fixed with handrails 3 for convenient transportation.

[0023] When in use, the items are placed in the cart 1 for transfer, and the transfer work is carried out through the handrail 3 and the roller 2. When facing a large number of items that need to be stacked and transferred, the rotating rod 52 is rotated so that the position of the limit block 1 55 and the limit block 2 56 are parallel to the limit hole 54. At this time, the enclosure 40 is placed above the cart 1 so that the fixed column 42 enters the installation groove 45. At this time, the surface of the fixed column 42 contacts the inclined surface of the card block 402. At this time, the card block 402 drives the moving block 400 to move away from the fixed column 42, and at the same time drives the short rod 49 to move synchronously. The short rod 49 is moved, and the surface of the short rod 49 contacts the through hole 48, so that the circular plate 47 rotates, which can make the short rods 49 and the moving block 400 move radially synchronously. At this time, the spring 401 is stretched. When the position of the slot 43 is parallel to the block 402, the spring 401 is released, driving the moving block 400 and the block 402 to enter the slot 43, so that the block 402 and the slot 43 are limited to each other. At this time, the fence 40 is limited to the cart 1, which can increase the height of the cart 1, facilitate the stacking and transportation of goods, and improve the efficiency of use. When the rotating rod 52 is reversed, the positions of the limit block 1 55 and the limit block 2 56 are staggered with the position of the limit hole 54. The surface of the limit block 1 55 conflicts with the surface of the pull plate 404, so that the pull plate 404 cannot be pulled, which can avoid accidentally pulling the pull plate 404 and causing the block 402 to fall off the card slot 43. When the enclosure 40 is not needed, the rotating rod 52 is rotated so that the positions of the limit block 1 55 and the limit block 2 56 are parallel to the position of the limit hole 54. At the same time, when the rotating rod 52 is rotated, the surface of the rubber strip 2 53 conflicts with the surface of the rubber strip 1 51, so that The deformation does not affect the forward rotation of the rotating rod 52. When the rubber strip 2 53 is located between the rubber strip 1 51, the rotating rod 52 can be stabilized to prevent the rotating rod 52 from rotating on its own. At this time, pulling the pull plate 404 can drive the fixed rod 403, the movable block 400, and the card block 402 to disengage from the card slot 43. At this time, the rotating rod 52 is reversed again, and the pull plate 404 is located between the limit block 1 55 and the limit block 2 56. The limit block 2 56 and the limit hole 54 are staggered. At this time, pulling the pull plate 404 on the other side again can remove the enclosure 40.

[0024] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
