Description

Technical Field

[0001] This utility model relates to a foot-operated trash can, and more particularly to a novel foot-operated trash can, belonging to the field of novel multi-link transmission opening structure. Background Technology

[0002] Foot-operated trash cans are one of the most common trash can products on the market. Their opening mechanisms mainly include a seesaw principle opening mechanism and a wire-rotating opening mechanism. These two mechanisms have the following disadvantages:

[0003] The main disadvantages of the seesaw-style lid opening structure are that it takes up a lot of space. The foot pedal needs to leave enough space to swing up and down, which reduces the capacity of the inner bin and increases subsequent transportation costs. In addition, due to inertia and center of gravity, the trash can is prone to wobbling forward when the lid is opened, which affects the user experience.

[0004] The structure of the iron wire rotating cover is relatively simple. Its main disadvantage is that the iron wire is relatively easy to deform, so the opening angle is difficult to control during production. The high requirement for the iron wire angle leads to high production difficulty and poor quality control. Utility Model Content

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0033] This utility model discloses a novel foot-operated trash can, which differs from traditional seesaw-style or wire-rotation-style lid opening structures. It features a multi-stage linkage transmission mechanism to achieve the opening action of the upper lid 4. Its overall structure is as follows: Figure 1 and Figure 2 As shown, the main structural components include: outer barrel body 1, inner barrel 2, mouth ring seat 3, upper cover 4, base 5, foot pedal 6, and a multi-stage linkage transmission mechanism for driving the upper cover 4 to flip.

[0034] The outer barrel 1 is usually made of stainless steel, which has advantages such as durability and wear resistance; the mouth ring seat 3 is engaged at the top opening of the outer barrel 1; the inner barrel 2 is the main place to hold garbage and is located inside the outer barrel 1; the base 5 serves as the bottom support and is engaged and connected to the bottom of the outer barrel 1.

[0035] After the base 9 and the mouth ring seat 3 are snapped together and assembled into the corresponding positions of the outer barrel 1, they are fastened to the outer barrel 1 by means of snap-fit ​​connection through the side rubber buckle structure, providing reliable support for the driving action of the multi-stage linkage transmission mechanism.

[0036] Preferably, several ribs are arranged inside the base 5 to support the inner bucket 2. The inner bucket 2 is not completely close to the bottom wall of the base 5, which can provide space for the multi-stage linkage transmission mechanism to be set at the bottom of the entire trash can.

[0037] Meanwhile, the front and rear side walls of the inner tub 2 will also have concave features to separate the multi-stage linkage transmission mechanism from the outer tub body 1 in the vertical direction.

[0038] The top cover 4 is positioned at the top opening of the outer barrel 1 and the inner barrel 2, and is driven to flip by a multi-stage linkage transmission mechanism that is uniquely designed in this invention.

[0039] like Figure 3 and Figure 4 As shown, the multi-stage linkage transmission mechanism includes: a triangular support transmission assembly, a bottom steel support link 73, a rotating arm C74, a plastic lower link 75, an upper steel support link 76, and an upper cover connector 77;

[0040] First, such as Figure 3 , Figure 4 as well as Figure 5 As shown, a foot pedal frame 55 is formed at the front end of the base 5, and the foot pedal 6 is hinged to the base 5 at the foot pedal frame 55 via a foot pedal pivot 61.

[0041] Secondly, the triangular support transmission assembly supports the foot pedal 6 in a triangular shape below the foot pedal 6, and the triangular support transmission assembly is limited in the elongated groove 52 on the base 5. Thus, the triangular support transmission assembly located below the foot pedal 6 moves back and forth along the elongated groove 52 on the base 5 under the limitation of the foot pedal 6.

[0042] Preferably, the triangular support transmission assembly specifically comprises a rotating arm A71 and a rotating arm 72; as shown below. Figure 3 , Figure 4 as well as Figure 5 As shown, the horizontal plate portion of the rotating arm A71 is limited and abuts against the foot pedal 6 below, and the column shaft 711 at the bottom of the inclined plate of the rotating arm A71 is located in the guide grooves 56 on both sides of the long groove 52; at the same time, the rotating arm B72 is hinged to the rotating arm A71 at one end and hinged to the rotating arm B connecting lug 57 on the base 5 at the other end.

[0043] Therefore, when the foot pedal 6 is stepped on, since the foot pedal 6 is connected to the base 5 through the foot pedal pivot 61, the foot pedal 6 can only rotate downwards when under force, which drives the rotating arm A71 to rotate downwards. Since one end of the rotating arm A71 is connected to the rotating arm B72 through the pivot structure, and the rotating arm B72 is hinged to the base 5, while the other end of the rotating arm A71 is limited to the base 5 through the elongated groove 52 and the guide groove 56, it can only move back and forth in a straight line. Therefore, when the rotating arm A71 rotates downwards, it also drives the rotating arm B72 to rotate downwards. This force keeps the trash can close to the ground and prevents it from shaking. This causes the lower end of the rotating arm A71 to move backwards in a straight line, thereby driving the bottom steel support rod 73 connected to it to move.

[0044] The bottom steel support rod 73 is connected to the rotating arm A71 at one end and to the rotating arm C74 at the other end.

[0045] The rotating arm C71 is hinged to the vertical connecting ear 53 on the base 5 via the rotating arm C pivot 741, so that the rotating arm C74 can rotate relative to the vertical connecting ear 53 on the base 5. The front end of the ramp of the rotating arm C74 is connected to a vertically distributed plastic lower connecting rod 75. Thus, when the bottom steel support connecting rod 73 pushes the rotating arm C71 backward, since the rotating arm C74 is connected to the vertical connecting ear 53 of the base 5 via the pivot structure, the rotating arm C74 can only rotate under force. The front end of the ramp of the rotating arm C74 is pushed upward by the bottom steel support connecting rod 73, thereby realizing the upward movement of the plastic lower connecting rod 75.

[0046] Preferably, a limiting groove 51 is provided on the base 5 at the position of the rotating arm C74, so that the vertical connecting ears 53 are distributed on both sides of the limiting groove 51. After the foot pressure at the foot pedal 6 is removed, the limiting groove 51 can prevent the rotating arm C74 from excessive rotation.

[0047] The upper steel support rod 76 is fixedly assembled with the lower plastic support rod 75 from the bottom end and can move upward synchronously with the lower plastic support rod 75.

[0048] The top end of the upper steel support rod 76 is connected to the upper cover connector 77. The upper cover connector 77 acts as a transmission component, on the one hand, it is hinged to the mouth ring seat 3 via the connector shaft 771, and on the other hand, the upper cover connector 77 passes through the opening 31 on the mouth ring seat 3 (e.g., Figure 6 (As shown) is then locked to the top cover 4 with screws. Thus,

[0049] Since the upper cover connector 77 is connected to the mouth ring seat 3 through a rotating shaft structure, the upper cover connector 77 can only rotate upward under force, and the upper cover 4 rotates upward together with the upper cover connector, thereby achieving the purpose of opening the cover.

[0050] Furthermore, to prevent the top cover 4 from falling back instantly and causing unnecessary damage after the foot pressure at foot pedal 6 is released, a slow-release damper 78 is fitted on the plastic lower connecting rod 75 via an extension lug 751 on one side. The slow-release damper 78 is fixed inside the slow-release mounting seat 54 on the base 5. When the plastic lower connecting rod 7 moves downward, it will hit the slow-release damper 78, thus slowing down the closing action of the cover.

[0051] Therefore, for the novel foot-operated trash can disclosed in this utility model, when the lid is closed, as follows: Figure 7 As shown; if you want to open the cover with your foot, as Figure 8 As shown, when the foot pedal 6 is pressed down, the foot pedal can only rotate downwards when it is under force, which drives the rotating arm A71 to rotate downwards. When the rotating arm A71 rotates downwards, it also drives the rotating arm B72 to rotate downwards, so that the lower end of the rotating arm A71 moves backwards in a straight line along the long groove 52.

[0052] When the rotating arm A71 slides backward, it drives the bottom steel support rod 73 connected to it to move backward as well, thereby pushing the rotating arm C74 connected to the other end of the bottom steel support rod to rotate. When the rotating arm C74 is under force, it can only rotate. Driven by the bottom steel support rod 73, the front end of the ramp of the rotating arm C74 rotates upward, driving the lower plastic connecting rod 75 and the upper steel support rod 76 to move upward together. The upper steel support rod 76 is under force to the upper cover connector 77. The upper cover connector 77 can only rotate upward under force. The upper cover 4 and the upper cover connector 77 are fixed by screws, so they also rotate upward together, thus completing the purpose of opening the cover.

[0053] When it is necessary to close the trash can lid... Figure 7 In the indicated state, simply release the foot pedal 6. Due to gravity, the upper cover 4 will naturally rotate downwards, pushing the relevant components to move in the opposite direction and reset. When the plastic lower connecting rod 75 moves downwards, it will hit the slow-release damper 78, making the closing action slow down to achieve the effect of gently closing the cover.

[0054] In summary, the main components of the novel foot-operated trash can disclosed in this utility model are basically the same as those of traditional trash cans. The main difference lies in the multi-stage linkage transmission mechanism that works with the foot pedal. The opening of the lid is achieved by using a multi-stage linkage transmission method. The entire multi-stage linkage transmission mechanism is set along the bottom and sides of the trash can, occupying little space and optimizing the swing space of the foot pedal to ensure stable foot pedal operation. This reduces the product height for the same capacity and lowers subsequent transportation costs. At the same time, the designed multi-stage linkage transmission mechanism is easier to assemble and fit, reducing production assembly requirements and making the quality control of the trash can easier. Furthermore, it eliminates the need for iron wire, effectively avoiding problems such as deformation, and maintaining stable mechanical performance during long-term use of the trash can.

[0055] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
