Description

Technical Field

[0001] The present invention relates to a dustbin, specifically a buried dustbin. The dustbin is not on the ground but buried underground, and the plane where the large cover plate of the dustbin is located is flush with the ground. Background Art

[0002] Currently, most dustbins are located on the ground. There are also a small number of dustbin bodies buried underground, but the feeding ports or the trash cans are still above the ground. Whether the whole or part of the dustbin is above the ground, the advantage is that it is easy to throw garbage, while the disadvantages are that it affects the city appearance, looks unsightly, and occupies space. If the dustbin is completely buried underground, it can not only beautify the environment but also save space. For example, buried dustbins can be set beside roads, on roads in cities, tourist attractions, etc. There is a trash can in the dustbin, and the garbage is placed in the trash can.

[0003] When the dustbin is buried underground, the garbage throwing habits of citizens need to be changed. Instead of throwing garbage by hand, they need to use their feet to open the small cover plate 3 on the ground. Such a dustbin is not currently available on the market, nor is such a cover plate opening mechanism.

[0004] The technical problem encountered is that the buried dustbin is buried in positions such as sidewalks. It should neither trip pedestrians nor prevent pedestrians from opening the dustbin cover plate with their feet. After the garbage is thrown, the cover plate can easily return to its original position. Summary of the Utility Model

[0005] To solve the above technical problems, the present invention provides the following technical solutions.

[0006] The first technical solution. There is a large cover plate 2 on the upper part of the buried dustbin. There is a small cover plate 3 in the middle of the large cover plate 2. The small cover plate 3 is opened or closed through an opening mechanism. When closed, the small cover plate 3 is flush with the large cover plate 2.

[0007] The opening mechanism includes a support block 4, a caster 5, a two-link, and a Z-shaped rod 6. The large cover plate 2 is provided with a first hole 7. The caster 5 in the shape of a cylinder or a large drum is located below the large cover plate 2, and its first shaft 8 is parallel to the plane where the large cover plate 2 is located. The caster 5 extends out of the first hole 7 and is 5 cm to 8 cm higher than the large cover plate 2.

[0008] One end of the support block 4 is fixedly connected to the lower part of the large cover plate 2. The other end of the support block 4 is provided with a second hole 9 that cooperates with the first shaft 8 of the caster 5. The caster 5 and the short connecting piece 10 rotate together around the first shaft 8. One end of the long connecting piece 11 is rotatably connected to the short connecting piece 10 to form a two-link. The other end of the long connecting piece 11 is movably connected to one end of the Z-shaped rod 6.

[0009] The Z-shaped rod 6 is in a Z-shape, with the rods at both ends parallel to each other. The other end of the Z-shaped rod 6, namely the shaft 12, is rotatably connected to the large cover plate 2 and fixedly connected to the small cover plate 3. The small cover plate 3 can be turned over as the shaft 12 rotates.

[0010] The small cover plate 3 closes the garbage delivery port, and the large cover plate 2 and the small cover plate 3 are in the same plane when the garbage bin is not in use. When throwing garbage, it is necessary to open the small cover plate 3 to expose the garbage delivery port. The cover opening mechanism is used to open the small cover plate 3. First, one end of the cover opening mechanism is connected to the small cover plate 3, and the other end is installed on the large cover plate 2, and the mounting base is the support block 4. Most of the casters 5 are located under the large cover plate 2, and 5 cm to 8 cm are exposed above the large cover plate 2. It is necessary to prevent pedestrians from tripping and to easily enable pedestrians to flip the small cover plate 3 with their feet. Therefore, the height of the casters 5 above the large cover plate 2 should not be too high or too low. The cylindrical caster 5 is the most suitable, and the drum-shaped caster 5 is also acceptable. In order to save effort, the first axis 8 of the caster 5 should be parallel to the plane where the large cover plate 2 is located. In fact, the caster 5 drives the Z-shaped rod 6 to rotate through the two-link mechanism, and the transmission is achieved through the mechanically basic two-link mechanism. If it is a three-link, four-link or other form, it belongs to adding parts on the basis of the two-link, and the structure is equivalent.

[0011] The short connecting piece 10 in the two-link rod is to be connected to the caster 5. The short connecting piece 10 can be connected to the A-axis 8 of the caster 5 or directly connected to the caster 5, both of which are fixed connections. In this way, it can be ensured that the caster 5 and the short connecting piece 10 rotate together. Rotating together means that the rotation angle is the same, including synchronous rotation. Synchronous rotation means that the rod direction of the short connecting piece 10 coincides with the diameter of the caster 5. That is, rotating together includes two types: coincidence and intersection of the rod direction and the diameter.

[0012] The position of the cover opening mechanism is not limited, and can be on the left side or the right side of the small cover plate 3.

[0013] When the rotating shaft 12 rotates, the small cover plate 3 turns over. If the small cover plate 3 is rectangular, the rotating shaft 12 should be parallel to one side of the rectangle; if the small cover plate 3 is circular or elliptical, the rotating shaft 12 should be parallel to the diameter or perpendicular to the symmetry line of the ellipse.

[0014] Second technical solution: Based on the first technical solution, the first axis 8 of the caster 5 is parallel to the rotating axis 12 of the Z-shaped rod 6, and the other end of the long connecting piece 11 is movably connected to one end of the Z-shaped rod 6, which means a rotational connection.

[0015] The flipping direction of the caster 5 is parallel to the small cover plate 3, which is the most labor-saving situation.

[0016] The third technical solution. On the basis of the first technical solution, the spatial angle between the first shaft 8 of the caster 5 and the rotating shaft 12 of the Z-shaped rod 6 is within the range of 1 degree to 30 degrees. The other end of the long connecting piece 11 is movably connected to one end of the Z-shaped rod 6, which means a sliding connection and slides within a chute.

[0017] In special cases, due to reasons such as the installation position and installation space, the flipping directions of the caster 5 and the small cover plate 3 are not completely consistent and form a certain angle, for example, within 30 degrees. At this time, correspondingly, a slot is opened at the end of the long connecting piece 11 where it is connected to the Z-shaped rod 6, and one end of the Z-shaped rod 6 can slide within the slot. The so-called spatial angle means that the first shaft 8 and the rotating shaft 12 may be in one plane or may not be in one plane. If they are not in one plane, there will also be an angle through geometric projection, which is the spatial angle.

[0018] The fourth technical solution. On the basis of the first technical solution, the other end of the support block 4 is provided with a second hole 9 that cooperates with the first shaft 8 of the caster 5, which means that the first shaft 8 is rotatably connected to the second hole 9.

[0019] The caster 5 and the short connecting piece 10 rotate together around the first shaft 8, which means that the first shaft 8 is fixedly connected to the caster 5 and the short connecting piece 10 together, or the short connecting piece 10 is fixedly connected to the caster 5, and the caster 5 is fixedly connected to the first shaft 8.

[0020] If the first shaft 8 of the caster 5 can rotate within the second hole 9 of the support block 4, then the caster 5 and the short connecting piece 10 can be respectively fixedly connected to the first shaft 8 and rotate together with the first shaft 8. Or the short connecting piece 10 is fixedly connected to the caster 5, and the caster 5 is fixedly connected to the first shaft 8.

[0021] The fifth technical solution. On the basis of the first technical solution, the other end of the support block 4 is provided with a second hole 9 that cooperates with the first shaft 8 of the caster 5, which means that the first shaft 8 is fixedly connected to the second hole 9.

[0022] The caster 5 and the short connecting piece 10 rotate together around the first shaft 8, which means that the short connecting piece 10 is fixedly connected to the caster 5, and the caster 5 is rotatably connected to the first shaft 8.

[0023] At this time, the first shaft 8 is fixed, the short connecting piece 10 is fixedly connected to the caster 5, and the caster 5 is rotatably connected to the first shaft 8.

[0024] The sixth technical solution. On the basis of the first technical solution, the direction of the short connecting piece 10 coincides with the diameter direction of the caster 5.

[0025] It means that the short connecting piece 10 is fixedly connected to the caster 5, and the direction of the rod coincides with the diameter direction, belonging to synchronous rotation. The short connecting piece 10 is a straight rod.

[0026] The seventh technical solution: Based on the first technical solution, the direction of the short connecting piece 10 intersects with the diameter direction of the caster 5 .

[0027] It means that the short connecting piece 10 is fixedly connected to the caster 5, but the direction of the rod crosses the diameter direction, and they do not rotate synchronously, but still rotate together.

[0028] The eighth technical solution: Based on the first technical solution, the rotating shaft 12 is rotatably connected to the first shaft sleeve 13, the first shaft sleeve 13 is fixedly connected to the bottom of the large cover plate 2, and the rotating shaft 12 is fixedly connected to the small cover plate 3 through the fifth connecting rod.

[0029] At this time, there is only one axle sleeve, and the first axle sleeve 13 plays a supporting role as the same as the support block 4. Fixed connection is easy to achieve, such as welding the rotating shaft 12 and the small cover plate 3 together through the fifth connecting rod.

[0030] The ninth technical solution. On the basis of the first technical solution, the rotating shaft 12 passes through the shaft sleeve A 13 and the shaft sleeve B 14 in sequence, the rotating shaft 12 is rotatably connected to the shaft sleeve A 13, the shaft sleeve A 13 is fixedly connected under the large cover plate 2, the rotating shaft 12 is fixedly connected to the shaft sleeve B 14, and the shaft sleeve B 14 is fixedly connected under the small cover plate 3. At this time, there are two shaft sleeves. The shaft sleeve B 14 and the connecting rod E are in a substitution relationship.

[0031] The tenth technical solution. On the basis of the ninth technical solution, it also includes a C-shaft sleeve 15 and a D-shaft sleeve 16. The other end of the Z-shaped rod 6, i.e., the rotating shaft 12, passes through the A-shaft sleeve 13, the B-shaft sleeve 14, the C-shaft sleeve 15, and the D-shaft sleeve 16 in sequence. The rotating shaft 12 is rotatably connected to the D-shaft sleeve 16, and the D-shaft sleeve 16 is fixedly connected below the large cover plate 2. The rotating shaft 12 is fixedly connected to the C-shaft sleeve 15, and the C-shaft sleeve 15 is fixedly connected below the small cover plate 3. The B-shaft sleeve 14 and the C-shaft sleeve 15 are in a substitution relationship with the E-connecting rod.

[0032] The shaft sleeve is added to better fix the small cover plate 3 and position it, so as to achieve a better flipping effect.

[0033] Eleventh technical solution: Based on the tenth technical solution, the second shaft sleeve 14 and the third shaft sleeve 15 are fixedly connected below the small cover plate 3 , which means they are connected to the front or rear of the small cover plate 3 .

[0034] The shaft sleeve is connected to the middle position of the small cover plate 3. When the small cover plate 3 is turned up, the garbage delivery port is divided into two. The shaft sleeve is connected to one end of the small cover plate 3, and the small cover plate 3 is on one side of the garbage delivery port after opening.

[0035] The twelfth technical solution. Based on any one of the first to eleventh technical solutions, the circumferential surface of the caster 5 has anti-skid ribs. The cylindrical shape means that the circumferential surface is generally thick above and below, and the drum shape means that it is large in the middle and small at both ends. The anti-skid ribs can increase the resistance, making it easier to flip the small cover plate 3.

[0036] The technical effect achieved is: the underground trash can is located in sidewalks, scenic spots and other places, does not affect pedestrians walking, and the cover can be opened or closed with feet, making garbage disposal easy.

[0037] Regarding the division of technical features. According to different functions, the present invention has three technical features, namely, a large cover plate 2, a small cover plate 3, and a cover opening mechanism. The cover opening mechanism has a flipping function and can also be divided into a support block 4, a caster 5, a two-link rod, a Z-shaped rod 6, and a shaft sleeve.
