Technical Field

[0001] The invention belongs to the field of furniture products, and in particular relates to a gravity-based adaptive folding trash can. Background Art

[0002] Trash cans are containers for storing garbage, most of which are made of metal or plastic. When used, plastic bags are placed in them. When there is too much garbage, the bags can be tied up and thrown away. The existing household trash cans have a relatively simple structure. Uncovered trash cans are not beautiful and easy to emit odors during use, while covered trash cans are more cumbersome to use. In household scenes such as kitchens and bathrooms or in small spaces such as cars, covered trash cans will also take up a large space when there is no garbage and are not easy to operate. Therefore, it is necessary to design a trash can that can automatically open and close the lid and automatically adjust the volume according to the amount of garbage in the bucket. Summary of the invention

[0003] In view of the above problems, the present invention proposes a gravity-adaptive folding trash can, which can flip the lid according to the weight of the garbage and automatically adjust the volume of the trash can according to the weight of the garbage in the can, saving space and making people's daily life more convenient.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

A first cover is fixedly provided on the top of the body, and a flippable second cover is provided on the first cover. A liftable bearing platform is provided inside the body, and the bearing platform is connected to a connecting rod mechanism. The connecting rod mechanism drives the body to be retractable as the bearing platform is lifted or lowered.

[0006] Furthermore, the connecting rod mechanism includes a first guide rail, a second guide rail and a fixed bracket which are arranged perpendicular to the bottom of the barrel; the fixed bracket is located between the first guide rail and the second guide rail.

[0007] Furthermore, a first slider and a second slider are slidably provided on the first guide rail and the second guide rail respectively, the first slider is connected to one end of the first connecting rod, and the second slider is connected to one end of the second connecting rod.

[0008] Furthermore, a third connecting rod is rotatably provided on the fixed bracket, and two ends of the third connecting rod are respectively connected to the other end of the first connecting rod and the other end of the second connecting rod.

[0009] Furthermore, the bearing platform is connected to the second sliding block.

[0010] Furthermore, a push rod is provided on the first sliding block.

For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0022] To facilitate understanding of the present invention, the present invention is further explained below with reference to specific embodiments in conjunction with the accompanying drawings, and the specific embodiments do not constitute a limitation on the embodiments of the present invention.

[0023] Example 1

[0024] As introduced in the background technology, in view of the shortcomings of the prior art, the purpose of the present invention is to address the problems of existing home modernization and to provide a gravity-adaptive folding trash can that can be used in household scenes such as kitchens and bathrooms or in narrow spaces such as cars. When garbage is on either side of the flip cover, it will lose balance, and the side with garbage will drop. After the garbage slides into the garbage bag below, the cover will restore balance and be in a normal closed state. The adaptive folding system is mainly composed of a loading platform and a connecting rod mechanism. When the connecting rod mechanism moves, it is driven by the gravity of the garbage on the loading platform. When the garbage increases, the gravity of the garbage increases, pressing the loading platform to move downward, and the connecting rod rotates under the drive of the force, causing the push rod to rise, thereby increasing the volume inside the bucket.

[0025] like Figure 1 In the present embodiment 1, a gravity-adaptive folding trash can is provided, comprising a lid and a body 8, wherein the lid is hinged on the body and can be closed on the opening of the body, a first lid 1 is fixedly provided on the top of the body, and a flip-over second lid 4 is provided on the first lid 1; a flip-over lid 5 is provided in the middle of the second lid 4, and the opening and closing of the flip-over lid 5 is controlled by the dead weight of the garbage. When the garbage is located on either side of the flip-over lid 5, it will lose balance, and the side with the garbage will drop. After the garbage slides into the garbage bag below, the lid will restore its balance and be in a normally closed state. A liftable bearing platform is provided in the body, and the bearing platform is connected to a connecting rod mechanism, and the connecting rod mechanism drives the body to be retractable as the bearing platform is raised or lowered.

[0026] A connecting rod mechanism is provided at the bottom of the barrel to drive the barrel body 8 to extend and retract, and the connecting rod mechanism includes a first guide rail 9, a second guide rail 16 and a fixed bracket 14 arranged perpendicular to the bottom of the barrel; the fixed bracket 14 is located between the first guide rail 9 and the second guide rail 16, and close to one side of the first guide rail 9, and a first slider 11 and a second slider 18 are respectively provided on the first guide rail 9 and the second guide rail 16, and the first slider 11 and the second slider 18 are respectively hinged to one end of the first connecting rod 12 and the second connecting rod 17.

[0027] A third connecting rod 13 is provided on the fixed bracket 14 , and the third connecting rod 13 is hinged to the fixed bracket 14 at a position close to the 1 / 5 end of the first guide rail 9 , one end of the third connecting rod 13 is hinged to the first connecting rod 12 , and the other end of the third connecting rod 13 is hinged to the second connecting rod 17 .

[0028] A loading platform 10 is provided on the top surface of the first sliding block 11 , one end of the loading platform 10 is fixedly connected to the first sliding block by bolts, and the other end of the loading platform 10 extends horizontally into the cavity of the barrel body for carrying garbage.

[0029] A push rod 2 is provided on the second sliding block 18 , and the top end of the push rod 2 is connected to the bottom surface of the first barrel cover 1 .

[0030] The weight of the garbage on the loading platform 10 increases, which will cause the first slider to slide downward along the first guide rail. Driven by the first connecting rod 12, the third connecting rod 13 rotates around the hinge with the fixed bracket 14, and then the third connecting rod 13 pushes the second connecting rod 17 to move upward, thereby pushing the second slider 18 to rise, thereby prompting the push rod 2 to drive the first barrel cover 1 to rise. The barrel body is made of silicone or waterproof cloth. There are multiple parallel steel rings inside the barrel body, and the barrel body can be folded to achieve the purpose of extending the barrel body 8.

[0031] In addition, the first bucket cover 1 is hinged with the second bucket cover 4, and a flap that rotates around an axis is provided in the middle of the second bucket cover 4. When dumping garbage or adding a new garbage bag to the device, it is necessary to manually open the second bucket cover 4, remove the garbage bag pressure ring, replace the garbage bag and then press the pressure ring on, and close the second bucket cover 4, so that the garbage can can work normally.

[0032] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative work on the basis of the technical solution disclosed in the present invention should be included in the scope of protection of the present invention.
