Description

Technical Field

[0001] The utility model relates to the technical field of display racks, in particular to a portable windproof display rack. Background Art

[0002] On-site health science promotion activities are an effective way to improve the health literacy of the entire population. They are also a key means of strengthening publicity and promotion to enhance the impact of health science promotion activities. Only through extensive publicity and promotion can more people understand and participate in health science promotion activities. Squares, as a model of urban public space, are important venues for citizens' cultural life and are also the best venues for health science promotion. As a crucial promotional display device, mobile display stands play an irreplaceable role in promotional activities.

[0003] Current display racks on the market often suffer from instability after being deployed. Especially in outdoor environments, strong winds can easily cause them to fall over, impacting the display and potentially posing a safety hazard. To improve stability, some display rack manufacturers install heavier bases to enhance wind resistance. While this approach improves the rack's stability to a certain extent, it also increases its overall weight, making it extremely inconvenient to carry and move. Utility Model Content

[0021] In order to be able to store the bracket 2, thereby reducing the height of the device and reducing the space occupied by the device, the bracket 2 includes a first connecting frame 21, the first connecting frame 21 is fixedly connected to the top surface of the base 1, and first storage cavities 22 are opened on the left and right sides of the top of the first connecting frame 21, and the upper ends of the two first storage cavities 22 are movably connected with connecting rods 23. A second connecting frame 24 is provided on the top of the first connecting frame 21, and second storage cavities 25 are opened on the left and right sides of the bottom of the second connecting frame 24. The upper ends of the surfaces of the two connecting rods 23 are respectively movably connected in the adjacent second storage cavities 25.

[0022] In order to fix the bracket 2 after it is unfolded, so that the bracket 2 maintains the current height and does not drop, first screw holes 26 are opened on the opposite sides of the side surfaces of the two connecting rods 23 and near the bottom, and second screw holes 27 are opened on the opposite sides of the side surfaces of the two connecting rods 23 and near the top. First bolts 28 are movably connected on the left and right sides of the inner side of the first connecting frame 21 and near the top, and one end of the first bolt 28 is threadedly connected to the adjacent first screw hole 26. Second bolts 29 are movably connected on the left and right sides of the inner side of the second connecting frame 24 and near the bottom, and one end of the second bolt 29 is threadedly connected to the adjacent second screw hole 27.

[0023] In order to facilitate the connection of the display poster to the bracket 2, the first connecting ring 12 is fixedly connected to the left and right sides of the inner side of the first connecting frame 21 and near the bottom, and the second connecting ring 13 is fixedly connected to the left and right sides of the inner side of the second connecting frame 24 and near the top.

[0025] Working principle: When the present invention is used, first connect the external water pipe to the water pipe joint 4, and then drain the water into the inner cavity of the base 1 through the water injection pipe 3, thereby increasing the weight of the device and making it less likely to be blown by the wind after the device is placed. When the device needs to be moved, twist the pipe cover 6 to remove it from the drain pipe 5, so that the water in the inner cavity of the base 1 is discharged through the drain pipe 5, thereby reducing the weight of the device. After the water in the base 1 is drained, twist the handle 11 to rotate the screw 8, and the screw 8 will move downward when it rotates. The screw 8 drives the connecting plate 9 to descend, and the connecting plate 9 drives the universal wheel 10 to descend. After the universal wheel 10 descends, it contacts the ground and lifts the base 1. At this time, the device can be pushed to move easily on the ground. In this way, the device can not only be placed It is stable and not easily blown down by the wind, and it is also convenient to carry and transport, which improves the practicality of the device. When the device is not in use, twist the first bolt 28 to move it out of the first screw hole 26, release the position of the connecting rod 23 in the first receiving chamber 22, and the connecting rod 23 descends to store the lower end in the first receiving chamber 22, and then twist the second bolt 29 to move it out of the second screw hole 27, release the position of the connecting rod 23 in the second receiving chamber 25, and the second connecting frame 24 descends to store the upper end of the connecting rod 23 in the second receiving chamber 25. In this way, the bracket 2 can be stored, the height of the device can be lowered, and the space occupied by the device when not in use can be reduced, which is convenient for placement when the device is loaded and transported.

[0026] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0027] The above embodiments merely illustrate several implementations of the present invention.
