Description

Technical Field

[0001] This utility model relates to the field of garbage bin technology, specifically to an anti-cutting structure for the inner bottom support of an underground garbage bin. Background Technology

[0002] Underground garbage bins are devices for temporary storage and disposal of garbage. On the market, there is a type of underground garbage bin kit made of rotomolded material. Structurally, it consists of an outer bin and an inner bin. The outer bin is fixed underground with an open top; the inner bin is placed inside the outer bin to hold the garbage. A dumping spout with a lid is located at the bottom of the inner bin. To remove the garbage, simply lift the inner bin so that the dumping spout is aligned with the dumping point, then open the lid, and the garbage inside the inner bin will be dumped out by gravity—very convenient.

[0003] A representative example is the patent document with application number CN202022509525.1, which discloses an impact-resistant inner bucket and the resulting underground garbage bin. It uses a U-shaped screw to connect the holding layer of the bottom cover and the base, allowing the holding layer to swing or shake slightly relative to the base during use, ensuring that garbage does not get stuck on the holding layer. Furthermore, the two ends of the U-shaped screw span a distance, dispersing the force on the holding layer and making it less prone to damage. This allows it to withstand impacts during long-term use, effectively extending its service life.

[0004] Although the technical solutions disclosed in the aforementioned patent documents can enable the holding layer to withstand impacts during long-term use, there are still limitations in practical applications, as follows: During the final waste removal process, the container layer needs to be flipped around its connection point with the base to improve waste removal efficiency. However, although the U-shaped screw can support and restrain the container layer, its closed U-shaped bottom prevents the layer from fully pressing against and against the end face of the U-shaped bottom. This makes the container layer susceptible to waste after flipping, causing it to slide along the U-shaped opening and exacerbating wear at the connection between the container layer and the U-shaped screw.

[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content

[0006] This utility model provides a cut-resistant structure for the bottom support of an underground garbage bin, aiming to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is: a cut-resistant structure for the inner bottom support of an underground garbage bin, the underground garbage bin including a base, the base including a chassis and a frame set in the chassis, the upper surface of the frame being provided with an inner bottom support, the inner bottom support being provided with at least one perforation, when there are multiple perforations, all the perforations are arranged along a straight line, the straight line being perpendicular to the extension line of the length direction of the frame; The anti-cutting structure includes a support member, and each of the perforations is provided with a support member corresponding to one of the support members; The support member is detachably connected to the frame. The support member includes a long line segment and a short line segment. The ends of the long line segment and the short line segment are integrally connected and set at a first predetermined angle. The long line segment passes through the perforation and is detachably connected to the frame. The axis of the long line segment is perpendicular to the upper surface of the frame. The short segment is configured such that when the inner tub bottom support is rotated around the long segment to a second predetermined angle, the peripheral side of the short segment abuts against the inner wall of the perforation to limit the displacement of the inner tub bottom support along the axial direction of the long segment.

[0008] In the above scheme, the first set angle can generally be 90 degrees or 120 degrees, or other angles. It is only necessary to satisfy the operation that the bottom support of the inner tub can slide up along the long line segment, flip along the corner between the long line segment and the short line segment, move to the short line segment, and support the bottom support of the inner tub through the short line segment.

[0009] In the above scheme, the second setting angle is formed by the inner bucket bottom tray flipping at the corner between the long and short line segments. The second setting angle needs to meet the requirement of being able to dump the garbage. Generally, in order to meet this requirement, it is preferable to flip the inner bucket bottom tray to be perpendicular to the short line segment. In practice, it is mostly flipped between 60 degrees and 120 degrees. However, it is also necessary to consider that the tilted inner bucket bottom tray will not cause the inner wall of the perforation to be bent or damaged by the periphery of the short line segment due to the influence of the weight of the inner bucket bottom tray. This is because the horizontal component force at the perforation is relatively large. Therefore, the second setting angle can be selected as 90 degrees with a range of ±15 degrees.

[0010] In the above scheme, the long line segment passes through the perforation and is detachably connected to the skeleton, where a threaded connection can be made.

[0011] In the above solution, the displacement of the inner tub bottom support along the axis of the long line segment can be limited by the cooperation of the support and the perforation, so that the flipping operation of the inner tub bottom support will not be affected.

[0012] Specifically, the inner tub base is directly guided to slide up along the long line segment until it reaches the corner between the long and short line segments. When the inner tub base rotates around the long line segment to the second set angle, the circumferential side of the short line segment abuts against the inner wall of the perforation to limit the displacement of the inner tub base along the axial direction of the long line segment.

[0013] Unlike the U-shaped screw in the prior art, the support in this application can not only assist the inner tub bottom tray in flipping, but also support the inner tub bottom tray, so that when the inner tub bottom tray is flipped to the second set angle, it can also prevent the inner tub bottom tray from displacing along the axis of the long line segment.

[0014] In a further technical solution, the long line segment and the short line segment are arranged at right angles to form an L-shaped structure.

[0015] The above design ensures that the inner tub base is stable when it is on a short line segment.

[0016] A further technical solution is that when multiple support members are provided, and the long line segment and the short line segment are arranged at right angles, the axes of all the short line segments are arranged in parallel; with the inside and outside of the chassis as a reference, when the inner barrel bottom support does not rotate around the long line segment, the end of the short line segment in at least one support member faces the inside of the chassis.

[0017] The design ensures that the bottom tray of the inner bin will not move up and down with the garbage.

[0018] Specifically, when the long line segment and the short line segment are set at right angles, the inner bucket base is placed horizontally on the frame. Then, the trash can is placed on the inner bucket base. As the amount of trash increases, the inner bucket base is prone to sticking to the trash or the bottom of the trash can. Once the trash can moves up and detaches from the inner bucket base, the inner bucket base is prone to flipping over, causing trash leakage. However, the end of the short line segment in at least one support member faces the inside of the chassis, which can prevent the inner bucket base from automatically flipping over. When it is necessary to flip the inner bucket base in the future, the support member is guided to face the outside of the chassis, and all the support members face the same side.

[0019] A further technical solution involves a bushing fitted around the outer periphery of the support member. This design helps prevent excessive friction at the perforation points.

[0020] Bushings are generally made of rubber.

[0021] A further technical solution involves a perforation diameter larger than the bushing diameter. This design ensures that the inner tub's bottom tray's flipping operation is unaffected. If the perforation diameter were smaller, the inner wall of the perforation would frequently rub against the bushing, reducing the lifespan of the inner tub's bottom tray.

[0022] A further technical solution involves providing a reinforcing ring on the surface of the inner tub base corresponding to the perforation. The reinforcing ring and the inner tub base are integrally formed using a rotational molding process. This design strengthens the area around the perforation, preventing bending and denting around the perforation caused by the inner tub base flipping over.

[0023] A further technical solution is that the inner diameter of the reinforcing ring is greater than or equal to the diameter of the perforation. This design prevents the reinforcing ring from rubbing against the bushing.

[0029] The working principle and advantages of this utility model are as follows: In this invention, the displacement of the inner tub bottom support along the axis of the long line segment can be limited by the cooperation of the support member and the perforation, so that the flipping operation of the inner tub bottom support will not be affected.

[0030] Specifically, the inner tub base is directly guided to slide up along the long line segment until it reaches the corner between the long and short line segments. When the inner tub base rotates around the long line segment to the second set angle, the circumferential side of the short line segment abuts against the inner wall of the perforation to limit the displacement of the inner tub base along the axial direction of the long line segment.

[0031] Unlike the U-shaped screw in the prior art, the support in this application can not only assist the inner tub bottom tray in flipping, but also support the inner tub bottom tray, so that when the inner tub bottom tray is flipped to the second set angle, it can also prevent the inner tub bottom tray from displacing along the axis of the long line segment.

[0036] See appendix Figure 1 - Figure 5 As shown, an anti-cutting structure for the inner bottom support of an underground garbage bin is provided. The underground garbage bin includes a base 10, the base 10 includes a chassis 1 and a frame 2 disposed in the chassis 1. The upper surface of the frame 2 is provided with an inner bottom support 3. The inner bottom support 3 is provided with at least one perforation 4. When there are multiple perforations 4, all the perforations 4 are arranged along a straight line, and the straight line is perpendicular to the extension line of the length direction of the frame 2. The anti-cutting structure includes a support member 5, and each of the perforations 4 is provided with a support member 5 in a one-to-one correspondence; The support member 5 is detachably connected to the frame 2. The support member 5 includes a long line segment 6 and a short line segment 7. The ends of the long line segment 6 and the short line segment 7 are integrally connected and set at a first predetermined angle. The long line segment 6 passes through the through hole 4 and is detachably connected to the frame 2. The axis of the long line segment 6 is perpendicular to the upper surface of the frame 2. The short segment 7 is configured such that when the inner tub bottom support 3 is rotated around the long segment 6 to a second set angle, the peripheral side of the short segment 7 abuts against the inner wall of the perforation 4 to limit the displacement of the inner tub bottom support 3 along the axial direction of the long segment 6.

[0037] In this utility model, the first set angle can generally be 90 degrees or 120 degrees, or other angles, as long as the inner tub bottom support 3 can slide up along the long line segment 6, flip along the corner between the long line segment 6 and the short line segment 7, and then move to the short line segment 7, and support the inner tub bottom support 3 through the short line segment 7.

[0038] In this invention, the second set angle is formed by the inner bucket bottom support 3 flipping at the corner between the long line segment 6 and the short line segment 7. The second set angle needs to meet the requirement of being able to dump the garbage. Generally, to meet this requirement, it is preferable to flip the inner bucket bottom support 3 so that it is perpendicular to the short line segment 7. In practice, it is mostly flipped between 60 degrees and 120 degrees. However, it is also necessary to consider that the tilted inner bucket bottom support 3 will not cause the inner wall of the perforation 4 to be bent or damaged by the peripheral side of the short line segment 7 due to the influence of the gravity of the inner bucket bottom support 3. This is because the horizontal component force at the perforation 4 is relatively large. Therefore, the second set angle can be selected as 90 degrees with a range of ±15 degrees.

[0039] In this invention, the long line segment 6 passes through the through hole 4 and is detachably connected to the skeleton 2, where a threaded connection can be made.

[0040] In this invention, the displacement of the inner tub bottom support 3 along the axis of the long line segment 6 can be limited by the cooperation of the support member 5 and the perforation 4, so that the flipping operation of the inner tub bottom support 3 will not be affected.

[0041] Specifically, the inner tub base 3 is directly guided to slide up along the long line segment 6 until it reaches the corner between the long line segment 6 and the short line segment 7. When the inner tub base 3 rotates around the long line segment 6 to the second set angle, the peripheral side of the short line segment 7 abuts against the inner wall of the perforation 4 to limit the displacement of the inner tub base 3 along the axial direction of the long line segment 6.

[0042] Unlike the U-shaped screw in the prior art, the support member 5 in this application can not only assist the inner tub bottom support 3 to flip, but also support the inner tub bottom support 3, so that when the inner tub bottom support 3 flips to the second set angle, it can also prevent the inner tub bottom support 3 from displacing along the axis of the long line segment 6.

[0043] Preferably, the long line segment 6 and the short line segment 7 are arranged at right angles to form an L-shaped structure.

[0044] With the above design, the inner tub base 3 is stable when it is on the short line segment 7.

[0045] Preferably, when multiple support members 5 are provided, and the long line segment 6 and the short line segment 7 are arranged at right angles, the axes of all the short line segments 7 are arranged in parallel; with the inside and outside of the chassis 1 as a reference, when the inner barrel base 3 does not rotate around the long line segment 6, the end of the short line segment 7 in at least one support member 5 faces the inside of the chassis 1.

[0046] Thanks to the above design, the inner bin bottom tray 3 will not move up and down with the garbage.

[0047] Specifically, when the long line segment 6 and the short line segment 7 are set at a right angle, the inner bucket base 3 is placed horizontally on the frame 2. Then, the trash can is placed on the inner bucket base 3. As the amount of trash increases, the inner bucket base 3 is prone to sticking to the trash or the bottom of the trash can. Once the trash can moves up and detaches from the inner bucket base 3, the inner bucket base 3 is prone to flipping over, causing trash leakage. However, the end of the short line segment 7 in at least one support member 5 faces the inside of the chassis 1, which can prevent the phenomenon of the inner bucket base 3 automatically flipping over. When it is necessary to flip the inner bucket base 3 later, the support member 5 is guided to face the outside of the chassis 1, and all the support members 5 face the same side.

[0048] Preferably, a bushing 8 is fitted onto the outer periphery of the support member 5. This design helps prevent excessive friction at the perforation 4.

[0049] Bushing 8 is generally made of rubber.

[0050] Preferably, the diameter of the perforation 4 is larger than the diameter of the bushing 8. This design ensures that the flipping operation of the inner tub base 3 is not affected. If the diameter of the perforation 4 is smaller, the inner wall of the perforation 4 will easily rub against the bushing 8 frequently, reducing the service life of the inner tub base 3.

[0051] Preferably, a reinforcing ring 9 is provided on the surface of the inner tub base 3 at the position corresponding to the perforation 4, and the reinforcing ring 9 and the inner tub base 3 are integrally formed by rotational molding. With the above design, the reinforcing ring 9 can strengthen the strength of the area around the perforation 4 and prevent the area around the perforation 4 from bending and denting due to the inner tub base 3 flipping over.

[0052] Preferably, the inner diameter of the reinforcing ring 9 is greater than or equal to the diameter of the perforation 4. This design prevents the reinforcing ring 9 from rubbing against the bushing 8.

[0053] Working principle: When the long line segment 6 and the short line segment 7 are set at a right angle, the inner bucket base 3 is placed horizontally on the frame 2. Then, the trash can is placed on the inner bucket base 3. As the amount of trash increases, the inner bucket base 3 is prone to sticking to the trash or the bottom of the trash can. Once the trash can moves up and detaches from the inner bucket base 3, the inner bucket base 3 is prone to flipping over, causing trash leakage. However, the end of the short line segment 7 in at least one support member 5 faces the inside of the chassis 1, which can prevent the phenomenon of the inner bucket base 3 automatically flipping over. When it is necessary to flip the inner bucket base 3 later, the support member 5 is guided to face the outside of the chassis 1, and all the support members 5 face the same side.

[0054] Subsequently, the inner tub base 3 is guided to slide upward along the long line segment 6 until it reaches the corner between the long line segment 6 and the short line segment 7, where the inner tub base 3 is guided to flip. When the inner tub base 3 flips around the long line segment 6 to the second set angle, the peripheral side of the short line segment 7 abuts against the inner wall of the perforation 4 to limit the displacement of the inner tub base 3 along the axial direction of the long line segment 6.

[0055] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
