Description

Technical Field

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

[0002] A trash can, also known as a waste bin or garbage bin, refers to a container for placing garbage. Household trash cans are usually used in conjunction with garbage bags, and garbage bags come in a variety of specifications. Sometimes people use disposable shopping bags from supermarkets as garbage bags. Since most existing trash cans do not have a telescopic folding mechanism, the size of the barrel mouth cannot be adjusted, and it is difficult to match different garbage bags.

[0003] The patent number authorized by China is CN220263930U, and the patent is named as a garbage can. The device includes: an outer barrel; an inner barrel, which is arranged in the outer barrel, and a gas channel is arranged on at least part of the bottom wall of the inner barrel; an air suction structure, and the air suction port of the air suction structure is located below the gas channel, and the air suction port is connected with the gas channel, so that when the air suction structure is started, the air in the inner barrel is sucked out by the air suction port through the gas channel. Under the action of the gravity of the inner barrel itself, the utility model has a tendency to move downward, and can better connect with the air suction port below, reducing the gap, thereby reducing the amount of air flowing into the air suction port from the gap when the air suction structure is started, so that more air entering the air suction port comes from the inner barrel, and then quickly forms a negative pressure between the inner wall of the inner barrel and the outer surface of the garbage bag, so that the garbage bag is quickly adsorbed and laid on the inner wall of the inner barrel, thereby improving the bag laying efficiency.

[0004] Although the above device improves the bag laying efficiency, there are still some problems when using the device:

[0005] 1. The barrel of the device does not have a telescopic and folding mechanism, and the size of its barrel mouth is fixed and cannot be changed, so it is difficult to match garbage bags of different sizes.

[0006] 2. The device does not have an adsorption fixing mechanism. When the device is used, it is easy to tip over due to accidental contact, causing garbage to fall out.

[0007] In view of the above situation, technological innovation is carried out based on the existing trash cans. Utility Model Content

[0008] The purpose of the utility model is to provide a retractable trash can to solve the problems raised in the above background technology.

[0009] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a retractable trash can, comprising a base and a magnetic plate, the inner wall of the base is provided with a rotating rod, and a torsion block is fixed at one end of the rotating rod, the outer wall of the rotating rod is provided with an external thread, and a limiting block is provided at one end of the external thread, an internal thread slider is provided on the outside of the external thread, and a barrel frame 1 is fixed to the top of the internal thread slider, one side of the barrel frame 1 is connected to a folded corrugated sheet, and the side of the folded corrugated sheet away from the barrel frame 1 is connected to the barrel frame 2, and the magnetic plate is magnetically fixed to the middle part of the bottom wall of the base.

[0010] Furthermore, the rotating rod is rotatably connected to the base, and the central axis of the torsion block coincides with the central axis of the rotating rod.

[0011] Furthermore, the external threads are provided in two groups, and the thread directions of the two groups of external threads are opposite.

[0012] Furthermore, support feet are arranged on both left and right sides of the bottom end of the base, and suction cups are fixed to the bottom ends of the support feet.

[0013] Furthermore, a release component is provided on one side of the suction cup, and the release component includes a connecting strip and a hand-pinching portion, and the hand-pinching portion is fixed to one end of the connecting strip.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the device is provided with a retractable and foldable side panel mechanism, which can change the size of the barrel mouth through the retractable and foldable barrel frame and corrugated sheets, so that the device can be suitable for garbage bags of different sizes, which is beneficial to improving the practicality of the device. At the same time, the device is provided with a suction cup, which can firmly fix the device on the ground to prevent the device from being accidentally kicked over, which is beneficial to improving the stability of the device.

[0015] 1. The utility model is provided with a rotating rod, a twist block, an external thread, a limit block, an internal thread slider, a barrel frame 1, a folding corrugated sheet and a barrel frame 2. When the user rotates the twist block, the rotating rod will rotate. At this time, the two internal thread sliders will move left and right along the external thread. Since the directions of the external threads are opposite, the two internal thread sliders will drive the barrel frame 1 and the barrel frame 2 to move toward or in the opposite direction. At the same time, the folding corrugated sheet will fold or stretch, thereby changing the size of the barrel mouth, so that the device can be suitable for garbage bags of various sizes. The magnetic suction plate can facilitate the disassembly of the device for maintenance and cleaning of debris entering the chute. Through the above structure, the device can change the size of the barrel mouth through the retractable and foldable barrel frame and the corrugated sheet, so that the device can be suitable for garbage bags of different sizes, which is conducive to improving the practicality of the device.

[0016] 2. The utility model provides supporting feet, suction cups, release components, connecting strips and hand-pinch parts. The supporting feet can lift the device a distance from the ground to prevent cockroaches and other insects from hiding in the bottom of the device due to the heat and darkness. The suction cups can firmly suck the tile floor or the smooth cement floor, thereby preventing the device from being displaced or accidentally kicked over. When it is necessary to release the suction cup from adsorbing the ground, the user can pinch the hand-pinch part and pull it upward. At this time, the hand-pinch part will pull up one side of the suction cup through the connecting strip, allowing air to enter the suction cup, thereby facilitating the release of the suction cup. Through the above structure, the device can be firmly fixed to the ground, preventing the device from being accidentally kicked over, which is conducive to improving the stability of the device.
