Abstract
Description
Technical Field
[0001] The utility model relates to the field of medical tools, in particular to a protective cover for a trash can. Background Art
[0002] Currently, due to cost considerations, a significant number of uncovered household waste bins are still in use in the wards of major hospitals across China. These bins, lacking lids to seal them, lack physical isolation during daily use. This leads to a greater risk of transmission of germs and viruses over long-term use compared to covered bins, especially in hospital environments. Although numerous covered bins are currently available, their procurement cost is higher than that of uncovered bins. A blanket purchase and replacement would not only increase overall costs but also lead to waste of existing uncovered bins, resulting in new waste. Therefore, a simple and effective method for retrofitting existing uncovered bins would be both economically and environmentally beneficial. However, many of the existing bins purchased by major hospitals are purchased in batches, resulting in variations in model, shape, and size, making a universal fit impossible.

BRIEF DESCRIPTION OF THE DRAWINGS
[0014] Figure 1 This is a schematic diagram of the top structure of the utility model;
[0015] Figure 2 This is a schematic diagram of the structure of the utility model installed on a round trash can;
[0016] Figure 3 This is a schematic diagram of the structure of the utility model installed on a square trash can. DETAILED DESCRIPTION
[0017] Combine Figure 1-3The protective cover for a trash can shown in FIG. includes a lid ring 1 made of rigid plastic, and a flexible sealing bag 2 disposed below the lid ring 1 and designed to fit over the opening of the trash can. The flexible sealing bag 2 is typically a plastic bag, and its primary function is to seal the opening of the trash can. To ensure a certain degree of overall strength, the flexible sealing bag 2 can be constructed using a two-layer structure. Of course, when using a thicker plastic film bag, a single-layer structure can also be used. The inner side of the flexible sealing bag 2 is connected to the lid ring 1, and an annular elastic band 3 is provided along the outer edge, tightening the opening of the trash can. Of course, a single flexible sealing bag 2 cannot fully cover trash cans of varying sizes, requiring adaptation to larger flexible sealing bag 2 models. However, the flexible sealing bag 2 is generally compatible over a wide range of sizes.
[0018] The cover ring 1 of the utility model is connected to the flexible sealing bag 2 on one hand, and is used as a garbage inlet on the other hand. A flip cover 4 is provided in the center to normally seal the center hole of the cover ring 1. Figure 1 As shown in FIG, the center of the cover ring 1 is generally provided with a central axis 5 extending radially along the cover ring 1. The flip cover 4 is mounted on the central axis 5 and forms a rotating engagement with the central axis 5, forming a rotating half-flip cover to meet daily needs. Of course, for some trash cans that require large garbage, in addition to using this type of flip cover 4, a full-body flip cover with a hinged side is also feasible, and the size of the cover ring 1 can be designed to be larger to accommodate large garbage.
[0019] Of course, due to the use of a flexible sealing bag 2, the lid ring 1 lacks support. Therefore, the present invention also provides a support mechanism around the lid ring 1 for supporting the lid ring 1 on the opening of the trash can. This support mechanism needs to provide sufficient support for the lid ring 1 to prevent it from collapsing, and it also needs to be versatile enough to accommodate trash cans of various shapes and sizes.
[0020] To this end, the support mechanism of the present invention can be designed as follows: Figure 1 As shown in the figure, the support mechanism includes a pair of active telescopic arms 6 and passive telescopic arms 7. Typically, the support mechanism includes two pairs of active telescopic arms 6 and passive telescopic arms 7, arranged in a cross-shaped arrangement. As the names suggest, the active telescopic arms and passive telescopic arms respectively have the functions of active telescopic and passive telescopic expansion.
[0021] Both include two telescopic rods arranged in parallel, the telescopic rods consisting of a sleeve 8 connected to the cover ring 1 and an inner rod 9 with one end passed through the sleeve 8. The middle parts of the inner rods 9 of the two telescopic arms are connected by a crossbeam 10, and the outer ends of the inner rods 9 are provided with hooks 11.
[0022] The crossbeam 10 of the active telescopic arm 6 is provided with a threaded sleeve 12 and a regulating screw 13. The inner end of the regulating screw 13 is connected to the cover ring 1 via a rotating head 14, and the outer end is provided with a screw head. The crossbeam 10 of the passive telescopic arm 7 is connected to the cover ring 1 via a tension spring 15.
[0023] During use, the active telescopic arm 6 can be extended or shortened by rotating the adjustment screw 13, thereby clamping the trash can's opening with the claws 11 provided at the ends of the telescopic rods on the active and passive telescopic arms. It is conceivable that all passive telescopic arms 7 could be replaced with active telescopic arms 6, but this would be costly and require simultaneous adjustment of multiple claws 11 during installation, making it less efficient.
[0024] In order to further enhance the grip of the hook 11 on the trash can wall, a rubber anti-sliding block is provided on the surface of the hook 11 facing the trash can wall. This structure is relatively simple and will not be described in detail again.
