Description

Technical Field

[0001] The present invention relates to the technical field of trash cans, and particularly to a trash can lid opening linkage structure. Background Art

[0002] At present, for trash cans with a large lid on the market, there is only one fixed rotating shaft connecting the trash can and the large lid. When the large lid is opened, it will be interfered by the components of the fixed rotating shaft. Therefore, in the design, the interfered part on the large lid has to be directly removed or separated from the large lid, which results in a reduction in the strength of the removed or separated part of the large lid or an incomplete appearance. In addition, for such a large lid with a single rotating shaft, when the large lid is opened, the large lid can only rotate backward unidirectionally around the rotating shaft, occupying a lot of space behind the rotating shaft of the large lid.

[0003] Therefore, to solve the above technical problems, a new technical solution is needed to solve this problem. In particular, a trash can lid opening linkage structure is provided. Summary of the Invention

[0004] The present invention provides a trash can lid opening linkage structure that can move inward and upward when opened to solve the technical problems that the body of the large lid of the existing large lid on the market will conflict with the trash can body when the large lid is opened, resulting in the removal of the conflicting part of the lid body during design, causing the large lid to be incomplete, and the existing large lid rotating shaft occupying the space behind the rotating shaft.

[0005] To achieve the above object, the following technical solutions are provided: A trash can lid opening linkage structure includes an independent trash can body and a large lid. A linkage structure is provided at one lid-closure end of the trash can body and the large lid. One end of the linkage structure is connected to the trash can body, and the other end of the linkage structure is connected to the large lid. The large lid can rotate around the linkage structure at the opening of the trash can body.

[0006] Preferably, the linkage structure includes a first link and a second link. The first link is connected to the trash can body through a first rotating shaft and connected to the large lid through a second rotating shaft. The second link is connected to the trash can body through a third rotating shaft and connected to the large lid through a fourth rotating shaft. The first link and the second link do not cross each other, and the first link is located below the second link.

[0007] Preferably, a limiting structure is provided below the second link. The connecting surface of the second rotating shaft with the large lid is provided with a protruding end, and the protruding end cooperates with the limiting structure.

[0008] Preferably, the limiting structure is an arc-shaped groove provided below the second link. The protruding end is the connecting end of the circular second rotating shaft.

[0009] Preferably, the second rotating shaft is located above the first rotating shaft, and the first connecting rod is arranged obliquely upward from the trash can body to the large cover; the third rotating shaft and the fourth rotating shaft are flush or the third rotating shaft is not higher than the fourth rotating shaft.

[0010] Preferably, the first connecting rod has an arc-shaped sheet structure; one side of the second connecting rod has a linear structure and the other side has an arc-shaped sheet structure provided with a limiting structure.

[0011] Preferably, the first connecting rod has an arc-shaped sheet structure; one side of the second connecting rod has a linear structure and the other side has an arc-shaped sheet structure provided with a limiting structure.

[0012] Preferably, the first rotating shaft, the second rotating shaft, the third rotating shaft and the fourth rotating shaft are pin shafts.

[0013] Advantages of the present invention: The present invention uses a connecting rod structure as the rotation center for opening the large cover, so that while the large cover rotates around the rotation center, the large cover moves upward and inward at the same time. Because the rotation center is composed of a connecting rod mechanism, and the rotation center of the connecting rod mechanism is not fixed, it can move upward and inward simultaneously when the large cover is opened. And the rotation center that moves upward and inward at the same time can prevent the large cover from being interfered by the structure of the fixed rotation center and save some space behind the rotation center.

[0023] As Figure 1 shown, a trash can lid opening linkage structure includes an independent trash can body 1 and a large lid 2. A connecting rod structure is provided at a lid closing end of the trash can body 1 and the large lid 2. One end of the connecting rod structure is connected to the trash can body 1, and the other end of the connecting rod structure is connected to the large lid 2. The large lid 2 can rotate around the connecting rod structure at the opening of the trash can body 1. The large lid and the trash can body use the connecting rod structure as the rotation center, so that the large lid can rotate around the rotation center when opening or closing. A gap is left between the connecting rod structure and the upper lid, so that the gravity of the large lid will not be transmitted to the connecting rod structure and the rotating shaft connecting the connecting structure, and the service life of the connecting rod structure is prolonged.

[0024] As Figure 2 、 Figure 3 、 Figure 4 and Figure 5 shown, the connecting rod structure includes a first connecting rod 3 and a second connecting rod 4. The first connecting rod 3 is connected to the trash can body 1 through a first rotating shaft 31 and connected to the large lid 2 through a second rotating shaft 32. The second connecting rod 4 is connected to the trash can body 1 through a third rotating shaft 41 and connected to the large lid 2 through a fourth rotating shaft 42. As Figure 3As shown, the first connecting rod 3 and the second connecting rod 4 do not cross each other and the first connecting rod 3 is located below the second connecting rod 4, so that the first connecting rod 3 and the second connecting rod 4 will not interfere with each other during operation. The first connecting rod 3 is rotatably connected to the trash can body 1 and the large cover 2 through the first rotating shaft 31 and the second rotating shaft 32. Since the linear distance between the first rotating shaft 31 and the second rotating shaft 32 is constant, the large cover 2 rotates with the linear distance between the first rotating shaft 31 and the second rotating shaft 32 as the radius and the first rotating shaft 31 as the center. Similarly, the second connecting rod 4 also makes the large cover 2 rotate in a circle with the third rotating shaft as the center and the linear distance between the third rotating shaft 41 and the fourth rotating shaft 42 as the radius. At the same time, the linear distance between the first rotating shaft 31 and the third rotating shaft 41 is constant, and the linear distance between the second rotating shaft 32 and the fourth rotating shaft 42 is constant. A four-sided connecting rod structure is formed by the first rotating shaft 31, the second rotating shaft 32, the third rotating shaft 41, the fourth rotating shaft 42, the first connecting rod 3 and the second connecting rod 4, wherein the first connecting rod 3, the second connecting rod 4 and the large cover form a movable part of the connecting rod. When the large cover 2 is opened, due to the connecting rod structure, the second connecting rod 4 will rotate upward clockwise, and at the same time drive the first connecting rod 3 to rotate clockwise toward the direction of the trash can body, that is, inward. Through the above connecting rod structure, the upper cover is opened to make a curved motion inward and upward at the same time.

[0025] like Figure 3 , Figure 4 and Figure 5 As shown, a limiting structure 5 is provided under the second connecting rod 4, and a protruding end is provided on the connecting surface of the second rotating shaft 32 with the large cover 2, and the protruding end cooperates with the limiting structure 5. Figure 4 As shown, when the large cover 2 is completely covered on the trash can body 1, the second rotating shaft 32 is located above the first rotating shaft 31, and the first connecting rod 3 is arranged upward from the trash can body 1 to the large cover 2. The third rotating shaft 41 is flush with the fourth rotating shaft 42 or the third rotating shaft 41 is not higher than the fourth rotating shaft 42. The first connecting rod 3 and the second connecting rod 4 do not cross each other and the first connecting rod 3 is located below the second connecting rod 4, so that the first connecting rod 3 and the second connecting rod 4 will not interfere with each other during operation. Figure 3 As shown, the limiting structure 5 is an arc-shaped groove arranged below the second connecting rod 4, and the protruding end is the connecting end of the circular second rotating shaft 32. The first connecting rod 3 is an arc-shaped sheet structure. One side of the second connecting rod 4 is a straight structure and the other side is an arc-shaped sheet structure with a limiting structure. An arc-shaped groove is arranged on one side of the arc line. During the movement of the second connecting rod, the protruding end of the second rotating shaft will move along the arc-shaped groove to the deepest part of the depression. At this time, the large cover 2 of the trash can is fully opened. Since the arc-shaped groove restricts the connecting end, the large cover 2 can no longer rotate. Figure 5 shown.

[0026] In the present invention, the rotating shaft can be any one that can realize the function of hinged rotation. Preferably, the first rotating shaft 31, the second rotating shaft 32, the third rotating shaft 41 and the fourth rotating shaft 42 are pin shafts.

[0027] The trash can lid opening structure of the present invention is mainly composed of a trash can body 1, a large lid 2 and a connecting rod structure. The connecting rod structure mainly includes: a first connecting rod 3, a first rotating shaft 31, a second rotating shaft 32, a second connecting rod 4, a second rotating shaft 41 and a second rotating shaft 42, wherein the trash can body 1, the first rotating shaft 31 and the third rotating shaft 41 are stationary. Figure 4 As shown, when the position of the large cover 2 is fixed, the position of the connecting rod mechanism is fixed, forming a unique rotation center. When the connecting rod mechanism moves with the opening of the large cover 2, its rotation center also moves upward and inward accordingly with the large cover 2. The moving rotation center can just avoid the large cover 2 when it is opened, so that the large cover 2 is not interfered by the trash can body 1. The inwardly moving rotation center can also move the large cover 2 inward, thereby reducing the displacement of the large cover 2 moving outward after opening, thereby saving the space occupied by opening the large cover 2. Figure 5 shown.

[0028] The present invention replaces the traditional rotary shaft connection structure between the cover and the body of the trash can with a connecting rod connection structure. Due to the connecting structure, the cover of the trash can does not simply rotate in a plane circle around the rotating shaft when in use, but the cover can generate a curved motion that not only rotates in a circle but also moves up and down under the action of the connecting rod structure and the rotating shaft. The connecting rod structure cooperates with the rotating shaft to enable the cover of the trash can to rotate in a circle and move up and down. Therefore, when the cover of the trash can is opened, the first connecting rod cooperates with the second connecting rod to enable the cover to move upward and inward while rotating in a circle, thereby solving the technical problem that the rear side of the cover of the traditional trash can only moves downward when rotating in a circle and conflicts with the body of the trash can.

[0029] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
