Description

A height-adjustable variable-capacity trash can

technical field

The invention relates to a kitchen article, in particular to a height-adjustable variable-capacity trash bin for kitchen use.

Background technique

The used trash can of family is mostly a container that is made into bucket shape with plastics at present, is covered with rubbish bag and dresses rubbish in the litter bin of opening, and after treating that rubbish is full, throws away after rubbish bag is proposed in the trash bin.

But in real life, all kinds of vegetables, food, etc. are packed in plastic bags. The length of the plastic packaging bags is inconsistent. The large plastic packaging bags are placed in the small trash can. After the bucket is full, no more garbage can be put in. The large plastic packaging bags have no effect; while the short plastic packaging bags are placed in the large trash can. After being placed on the upper edge of the trash can, the bottom of the plastic packaging bag is not in contact with the bottom of the trash can due to insufficient height. Once the garbage is put in, the plastic bag will fall to the bottom of the bucket or break, and the mouth of the garbage bag cannot be opened. very inconvenient. With the temporary enhancement of people's environmental protection, if plastic bags can be reused, it can save money and reduce white pollution.

Contents of the invention

The object of the present invention is to provide a height-adjustable variable-capacity garbage can, which is applied in the kitchen, changes the capacity of the garbage can, and is applicable to plastic garbage bags of different lengths.

The purpose of the present invention is achieved through the following technical solutions:

A height-adjustable variable-capacity trash can is shown in Figure 1, comprising: an outer cylinder 1, a rack 2, a boss 3, a rotating shaft 4, a gear 5, and an inner cylinder 6; the inner cylinder 6 is placed inside the outer cylinder 1, A gear 5 is installed on one side of the outer cylinder 1, and a rack 2 is made on the same side of the outer surface of the inner cylinder. The gear 5 meshes with the rack 2, and the rotating shaft 4 can be driven by the gear 5 to drive the rack 2 and the inner cylinder 6 to move up and down. , determine the position of the inner tube 6 in the outer cylinder 1 and fix the inner tube 6 at this position, and change the actual use height and capacity of the trash can.

The outer cylinder 2 is a cylindrical shape made of metal with one end closed. At the upper 1/3 of the height direction of the outer cylinder 2, there is a boss 3 on the left side of the outside, and a small gear 5 is installed in the middle through the handle. About 3 cm in diameter, see Figure 2.

The inner cylinder 6 is a bottomless cylinder made of metal, its height is 10 mm higher than that of the outer cylinder 1, its outer diameter is slightly smaller than the inner diameter of the outer cylinder 1, and there is a gap of about 2 mm, which is placed in the outer cylinder 1 Can freely rotate and move up and down, on the left side of the outer surface of the inner tube 1, a rack 2 is made along the vertical direction of the inner tube 1, see Fig. 3 .

One end of the rotating shaft 4 is bent at 90 degrees as a rotating handle, and the other end passes through the inner hole of the boss 3 and the pinion 5, so that it can move axially relative to the gear 5 and drive the gear 5 to rotate; 3 is longer than 3 cm, pull out the handle end to rotate the rotating shaft 4 and drive the rack 2 and the inner cylinder 6 to move up and down. When the inner cylinder 6 is in the desired position, push the handle back toward the gear 5, The curved handle part of rotating shaft 4 is blocked by the surface of outer cylinder 1, can not rotate again, and then inner cylinder 6 positions are fixed by gear 5.

Compared with the existing devices, the height-adjustable variable-capacity trash bin of the present invention can change both height and capacity, is convenient to use, has simple structure, is easy to operate, and has strong practicability.

Detailed ways

The technical solutions in the embodiments of the present invention are clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

Embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

A height-adjustable variable-capacity trash can according to an embodiment of the present invention, its preferred specific implementation is shown in FIG. 1 .

When using a plastic bag with a smaller length as a garbage bag, or when the capacity of the garbage can is smaller, pull out the handle on the rotating shaft 4, and turn the rotating shaft 4 so that the gear 5 drives the rack 2 to move downward. After the proper position is required, push the handle back toward the gear 5, the curved handle part of the shaft 4 is blocked by the surface of the outer cylinder 1, and will not rotate any more, and the position of the inner cylinder 6 is fixed by the gear 5. At this time, the height of the trash can Smaller and less capacity.

At this time, the garbage bag can be placed on the upper edge of the inner cylinder, and the garbage bag falls on the bottom of the inner cylinder. Even if heavy garbage is still put into the garbage bag, the garbage bag will not fall off, which is convenient for use.

When using a plastic bag with a larger length as a garbage bag, or when the capacity of the garbage can is larger, pull out the handle on the rotating shaft 4, and turn the rotating shaft 4 so that the gear 5 drives the rack 2 and the inner cylinder 6 to move upward. After the inner cylinder 6 is in the desired proper position, push the handle back toward the gear 5, the curved handle part of the rotating shaft 4 is blocked by the surface of the outer cylinder 1, and will not rotate any more, then the position of the inner cylinder 6 is fixed by the gear 5, at this time The actual height of the trash can is the height of the inner cylinder plus the partial height of the outer cylinder, and the actual used capacity is also increased.

At this time, the overall height of the garbage can has increased, the capacity has become larger, and the effect of larger garbage bags has been utilized.

In use, when the gear 5 drives the rack 2 and the inner cylinder 6 to move upward, because the inner cylinder 6 moves upward due to unilateral force, sometimes it is necessary to slightly lift the opposite side of the inner cylinder 6 upward, so that the inner cylinder 6 can move upward more smoothly.

The height-adjustable variable-capacity trash can provided by the embodiment of the present invention can easily change the capacity and height of the trash can, and can adapt to garbage bags and plastic packaging bags of different sizes, so that some plastic packaging bags can be reused. It not only saves money, but also reduces white pollution.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
