Description

Technical Field

[0001] It involves underground garbage bins, especially in an environment without electricity or power, where manual garbage removal is required. Background Art

[0002] In the prior art, most of the garbage bins are above ground, and a small number of garbage bins are buried underground, but the garbage inlet is still on the ground. Passers-by throw garbage by hand, and the main part located underground is turned over to the ground by a hydraulic cylinder or a motor, and then the garbage is removed.

[0003] The garbage bin or part of it is located on the ground, which affects the city appearance and takes up space. All garbage bins can be placed under the ground, named underground garbage bins. There is a trash can in the garbage bin, and the garbage is placed in the trash can. Underground garbage bins can be set up on the roads and roadsides in urban areas and tourist attractions, which beautifies the environment, does not take up space, and the garbage bins are for passers-by to walk on. In fact, except for residential areas, if electricity is to be supplied near roads and scenic spots, it will be a big project for the municipal government. In many places, roads and sidewalks are without electricity and power. The technical problem of underground garbage bins is: when the garbage is full of garbage bins, how to remove the garbage in an environment without electricity and power? Utility Model Content

[0004] In order to solve the above technical problems, the present invention provides the following technical solution, which can mechanically move the garbage bin from underground to the ground and then remove the garbage.

[0005] The first technical solution. An underground garbage bin in a non-electric and non-powered environment, the rear end of the cover plate 2 above the bin 1 is connected to the bin 1, a handle 3 is provided at the front of the cover plate 2, the bin 1 includes two upper and lower frames, namely an upper frame 4 and a lower frame 5, the frames are connected end to end by four connecting rods, and four columns connecting the four corners of the frames, a slide 6 is provided on each side of the bin 1, symmetrically arranged, each slide 6 is composed of two guide rails, the guide rails connect the upper frame 4 and the lower frame 5, the pulleys 7 on both sides of the lifting platform 9 correspond to the slides 6 on both sides of the bin 1 one by one, respectively, the upper frame 4 and the movable frame 8 above it are connected by a hinge, the hinge is located at the rear end of the upper frame 4, one end of the connecting rod mechanism is connected to the front of the movable frame 8, and the other end is connected to the lifting platform 9, and the lifting platform 9 is arranged horizontally; the movable frame 8 is connected to the bin 1 through a lifting mechanism.

[0006] The movable square frame 8 is part of the box body 1 and is located between the cover plate 2 and the upper square frame 4. The front end and the rear end of the square frame refer to one of the four connecting rods connected end to end, namely the front connecting rod and the rear connecting rod; while the rear part of the square frame refers to the rear section of the connecting rods on the left and right sides, excluding the rear connecting rod. The horizontally arranged lifting platform 9 moves up and down through the slideway 6, and the sanitation worker pulls the handle 3 to open the cover plate 2, and the lifting mechanism drives the movable square frame 8, the connecting rod mechanism and the lifting platform 9 to move in sequence.

[0007] The second technical solution. On the basis of the first technical solution, the horizontally arranged lifting platform 9 means that the slideway 6 is located at the middle position between the two sides of the box body 1, and the number of pulleys 7 on each side is two, and the two pulleys 7 are arranged vertically.

[0008] Keeping the lifting platform 9 horizontally arranged is to ensure smooth up and down movement and prevent it from bumping into the square frame. There are many ways to keep it horizontal. For example, if the slideway 6 is at the middle position on the left and right sides, the front and rear of the lifting platform 9 will be in a balanced state, and the two vertically arranged pulleys 7 moving in the slideway 6 will also play a role in keeping it horizontal.

[0009] The third technical solution. On the basis of the first technical solution, the horizontally arranged lifting platform 9 means that the slideway 6 is not at the middle position between the two sides of the box body 1, and a counterweight is provided correspondingly below the lifting platform 9.

[0010] If the slideway 6 is not at the middle position due to reasons such as the installation position, the method of using a counterweight can be adopted to balance it so that the lifting platform 9 is in a horizontal state.

[0011] The fourth technical solution. On the basis of the first technical solution, the two ends of the slideway 6 are provided with limit pieces. It is not easy to restore the pulley 7 when it slides out of the slideway 6, so limit pieces are added at both ends of the slideway 6.

[0012] The fifth technical solution. On the basis of the first technical solution, the handle 3 is one of a visible handle, a concealed handle or a ring handle. There are chains on both sides of the box body 1, one end is connected to the cover plate 2, and the other end is connected to the upper square frame 4 or the column. There are many types of handles. A visible handle means that a U-shaped rod passes through two holes of the cover plate 2. A concealed handle means that the handle can rotate. When not in use, the handle rotates to the lower part of the cover plate 2, and when in use, the handle rotates to the upper part of the cover plate 2. A ring handle means that one end of the ring passes through a hole of the cover plate 2, and the other end of the ring is used for hand-held. The chain pulls the cover plate 2 after it is opened to prevent damage to the hinge.

[0013] The sixth technical solution. On the basis of the first technical solution, there is a trash can on the lifting platform 9.

[0014] The seventh technical solution. On the basis of the first technical solution, the link mechanism refers to two sets that are symmetrically arranged left and right, and each set is rotationally connected by a first link 12 and a second link 13. Connecting through two links is the simplest link mechanism.

[0015] The eighth technical solution. On the basis of the first technical solution, the link mechanism refers to two sets that are symmetrically arranged left and right, and each set includes a tripod 14. The tripod 14 is triangular. One angle of the tripod 14 is directly connected to the upper square frame 4, and the other two angles are respectively connected to the front part of the movable square frame 8 and the lifting platform 9 through links. The tripod 14 can be solid or hollow, for example, it is composed of three links connected end to end.

[0016] Compared with the two-link, using the tripod 14 for transmission has a greater bearing capacity and a more stable structure, giving full play to the stability of the triangle.

[0017] The ninth technical solution. On the basis of any one of the first, seventh, and eighth technical solutions, the movable square frame 8 is connected to the box body 1 through a lifting mechanism, which means that the rear end of the movable square frame 8 is connected to one end of a telescopic rod 15, and the other end of the spring 16 is connected to the lower square frame 5.

[0018] Here, the spring 16 refers to an iron spring, and the movable square frame 8 is opened through the lever principle.

[0019] The tenth technical solution. On the basis of any one of the first, seventh, and eighth technical solutions, the movable square frame 8 is connected to the box body 1 through a lifting mechanism, which means that the rear part of the movable square frame 8 is connected to the cross bar in the middle of the box body 1 through a gas spring 17, and the gas springs 17 are symmetrically arranged left and right.

[0020] Through experiments, it is found that the garbage bin is not heavy, and the pneumatic spring can lift the garbage bin well. For the in-ground garbage bin that is relatively small, the cross bar can be installed at the bottom such as the lower square frame 5. If the in-ground garbage bin is relatively large, the cross bar is installed in the middle of the box body 1.

[0021] The eleventh technical solution. On the basis of any one of the first, seventh, and eighth technical solutions, there is an eaves sealing plate 18 outside the upper square frame 4. The eaves sealing plate 18 is composed of four connecting plates connected end to end. The eaves sealing plate 18 is 1 to 5 centimeters lower than the height of the upper square frame 4, and the two are hermetically connected. The rear end of the cover plate 2 is connected to the box body 1, which means that the rear end of the cover plate 2 is connected to the eaves sealing plate 18 through a hinge. The cover plate 2 has a bevel around it, and the bevel has a clearance fit with the eaves sealing plate 18.

[0022] The in-ground garbage bin also has a problem, which is water accumulation during rain. To prevent rainwater from entering the garbage bin, the method adopted is to add an eaves sealing plate 18. The eaves sealing plate 18 surrounding the outside of the upper frame 4 should be 1 to 5 centimeters lower than the upper frame 4, and the two are hermetically connected. The cover plate 2 with a beveled edge is in clearance fit with the eaves sealing plate 18. In this way, most of the rainwater flows along the beveled edge to the side. Even if a small amount of rainwater accumulates on the eaves sealing plate 18, it cannot enter the garbage bin. The second problem is that the installation positions of the cover plate 2 and the movable square frame 8 overlap, and this installation position overlap is also called spatial interference. To solve this problem, the cover plate 2 can be installed on the eaves sealing plate 18, and the movable square frame 8 can be installed on the upper frame 4.

[0023] The twelfth technical solution. On the basis of any one of the first, seventh, and eighth technical solutions, the rear end of the cover plate 2 is connected to the box body 1, which means that a support plate is fixedly connected to the rear side of the box body 1, and the rear end of the cover plate 2 is connected to the support plate through a hinge. The support plate and the eaves sealing plate 18 are in a substitution relationship, as long as it is on the rear side of the box body 1. Another example is that a support square frame can also be used, as long as it can play a supporting role.

[0024] The thirteenth technical solution. On the basis of any one of the first, seventh, and eighth technical solutions, the front end or the front part of the movable square frame 8 is connected to the upper frame 4 through a buckle 19. The spring 16 and the gas spring 17 have been applying force to the movable square frame 8 to keep it open. The cover plate 2 plays a role in pressing down the movable square frame 8. In addition, a buckle 19 can also be installed between the movable square frame 8 and the upper frame 4. In this way, first open the cover plate 2, and then open the buckle 19. Under the action of the spring 16 or the gas spring 17, the garbage bin will rise.

[0025] The fourteenth technical solution. On the basis of the tenth technical solution, the included angle between the gas spring 17 and the cross bar is between 40 degrees and 80 degrees. The gas spring 17 forms a certain angle with the horizontal. Between 70 degrees and 80 degrees, it not only saves space but also has the most ideal rising speed of the garbage bin.

[0026] The achieved technical effect is that a person pulls the handle 3 to open the cover plate 2 and opens the buckle 19 structure. Through a mechanical method, the spring 16 or the gas spring 17 drives the link mechanism, the lifting platform 9, and the trash can to complete the lifting. It realizes that the garbage bin is buried underground as a whole in a power-free environment and can still transport garbage.

[0027] Division of technical features. It is divided into cover plate 2 + handle 3, box body 1 + slideway 6 + movable square frame 8 + eaves sealing plate 18, spring 16 (or gas spring 17), link mechanism, lifting platform 9 + pulley 7 + trash can, buckle 19 structure. Description of the Drawings
