Description

Technical Field

[0001] The utility model relates to the technical field of trash cans, in particular to a trash can with adjustable height. Background Art

[0002] Trash cans are containers for garbage. Most are made of metal or plastic. When in use, plastic bags are placed in them. When there is too much garbage, the bags can be tied up and thrown away. Trash cans are containers for "hiding dirt and filth" in people's lives. They are an indispensable daily necessity in people's lives and a reflection of social culture. With the continuous progress of society, the functionality of trash cans has also increased, so that they can be used in various environments to clean the trash cans more conveniently and effectively.

[0003] However, the height of existing trash cans is usually fixed. In this way, when people repeatedly throw garbage into the trash can, such as throwing garbage when washing vegetables in the kitchen, eating melon seeds, etc., they need to constantly bend down to throw garbage into the trash can, and often encounter the phenomenon that the garbage is thrown out of the trash can because the height of the trash can is not enough. The height cannot be adjusted according to the needs of the user, which brings inconvenience to life and also increases the cleaning work. Utility Model Content

[0004] The purpose of the utility model is to provide a trash can with adjustable height to solve the problem that the height of the existing trash cans mentioned in the above background technology is usually fixed and cannot be adjusted according to the needs of users, which brings inconvenience to life and also increases the cleaning work.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable height trash can, comprising an outer barrel, an inner barrel and a driving assembly, wherein a through hole is opened on one side of the outer barrel and a guide rail is arranged around the inner wall, and a slider matching the number and size of the guide rail is arranged around the outer wall of the inner barrel, and the driving assembly comprises adjusting screws respectively arranged on both sides of the inner wall of the inner barrel and passing through the bottom end of the inner barrel, and a transmission shaft passing through the through hole on one side of the outer barrel and rotatably connected to the adjusting screw.

[0006] Preferably, L-shaped support plates are fixedly connected to both sides of the inner part of the outer barrel.

[0007] Preferably, the inner barrel is slidably connected to the outer barrel guide rail via the slider, and a barrel cover is installed at the top of the inner barrel and the bottom end is threadedly connected to the adjusting screw.

[0008] Preferably, a nut is installed at the top end of the adjusting screw and a first bevel gear and a limit block are arranged at the bottom end.

[0009] Preferably, the transmission shaft is provided with a second bevel gear which meshes with the first bevel gear at the bottom end of the adjusting screw and can transmit power.

[0010] Preferably, a handle is installed at one end of the transmission shaft located outside the outer barrel.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

The trash can of the utility model is provided with a transmission shaft in the inner cavity of a slide rail on the inner wall of the outer barrel, and a slider is provided on the outer wall of the inner barrel, and the bottom end of the inner barrel is threadedly connected to an adjusting screw. When the height of the trash can needs to be adjusted, the handle at one end of the transmission shaft outside the outer barrel is rotated to drive the second bevel gear fixedly connected to the transmission shaft to rotate upward or downward. Since the second bevel gear and the first bevel gear are meshed with each other and the bottom end of the inner barrel is threadedly connected to the adjusting screw, the power transmitted by the second bevel gear will drive the adjusting screw to rotate left or right, thereby providing the inner barrel with power to rise or fall, so that the inner barrel can slide up and down along the outer barrel guide rail through the slider to adjust the height of the trash can.

[0023] See also Figures 1 to 4 The utility model provides a technical solution: a trash can with adjustable height, including an outer barrel 1, an inner barrel 2 and a driving assembly 3. A through hole 4 is opened on one side of the outer barrel 1, and a guide rail 5 is arranged around the inner wall. A slider 6 matching the number and size of the guide rail 5 is arranged around the outer wall of the inner barrel 2. The driving assembly 3 includes an adjusting screw 301 respectively arranged on both sides of the inner wall of the inner barrel 2 and passing through the bottom end of the inner barrel 2, and a transmission shaft 302 passing through the through hole 4 on one side of the outer barrel 1 and rotatably connected to the adjusting screw 301.

[0024] In this embodiment, the inner barrel 2 is slidably connected to the guide rail 5 on the inner wall of the outer barrel 1 through a slider 6, and is powered by the driving component 3 to move up and down to adjust the height of the trash can. The top of the inner barrel 2 is detachably connected to a barrel cover 7. When in use, pick up the barrel cover 7 and place the bottom of the garbage bag inside the inner barrel 2. The top of the garbage bag is put on the outer edge of the top of the inner barrel 2, and then the barrel cover 7 is buckled on the top of the inner barrel 2 to complete the replacement of the garbage bag.

[0025] In this embodiment, an L-shaped support plate 8 is fixedly connected to both sides of the inner part of the outer barrel 1. One side of the L-shaped support plate 8 is used to support the shaft body of the transmission shaft 302 located inside the outer barrel 1, and the top is rotatably connected to the adjusting screw 301 to cooperate with the limit block 9 to support and limit the displacement of the adjusting screw 301.
