Description

Technical Field

[0001] This utility model relates to the field of trash cans, and more particularly to municipal trash cans. Background Technology

[0002] Municipal trash cans generally refer to public waste collection containers set up and managed by city or local government departments. These cans are placed in public places such as streets, parks, and squares to provide convenient disposal locations for citizens and tourists, thus maintaining the cleanliness and hygiene of the city. The design, capacity, distribution density, and collection frequency of municipal trash cans are usually determined based on actual needs and urban management planning, with the aim of effectively controlling waste pollution, promoting resource recycling, and enhancing the city's aesthetics.

[0003] When using municipal garbage bins, garbage bags are placed inside the bin. The garbage bags are usually made of plastic. When the garbage bag is full, municipal workers open the bin and remove the garbage bag to replace it with a new one. During this process, if the garbage bag is filled with a lot of garbage, the garbage may be pressed tightly against the inside of the garbage bag when it is pulled out. If the garbage bag is too tightly pressed against the inner wall of the bin, it may be easy for the garbage bag to tear during the removal process.

[0004] Therefore, it is necessary to provide a new type of municipal waste bin to solve the aforementioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a municipal garbage bin.

The threaded rod is rotatably connected to the vertical plate and threadedly connected to the movable frame. One end of the threaded rod is fixedly connected to the driven bevel gear, and the driving bevel gear meshes with the driven bevel gear.

[0010] Preferably, the top two sides of the placement rack are rotatably connected to rotating plates, and the ends of the two rotating plates are fixedly connected to a rain cover. Limiting components for fixing the rotating plates are also installed on both sides of the placement rack.

[0011] Preferably, the limiting component includes a side plate and a fastening bolt. The side plate is fixedly connected to the side wall of the placement frame, and the fastening bolt is threadedly connected to the side plate.

When the two opening and closing doors are closed, the limiting plate on one side of the collection device is in contact with the inner wall of the placement rack, and the limiting plate on the other side of the collection device is in contact with the side wall of the opening and closing door.

[0016] Compared with related technologies, the municipal trash can provided by this utility model has the following beneficial effects:

[0017] Rotating the handle causes the drive bevel gear to rotate via the rotating rod, which in turn causes multiple driven bevel gears to rotate, which in turn causes multiple threaded rods to rotate. Through the rotation of the threaded rods, the moving frame moves the baffle outward under the limit of the insertion hole, so that the garbage bag is no longer attached to the baffle, making it easier to remove the garbage bag. This application uses four outwardly movable baffles to prevent the outer wall of the garbage bag from tightly adhering to the side wall of the baffle when the garbage bag is removed, thus making the garbage bag less likely to tear when removed.

[0025] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0026] Please refer to the following: Figures 1-6 ,in, Figure 1 A schematic diagram of the structure of the municipal trash can provided by this utility model; Figure 2 for Figure 1 A side view of the structure shown; Figure 3 for Figure 1 A partial structural diagram of the structure shown; Figure 4 for Figure 3 A partial cross-sectional view of the structure shown. Figure 5 for Figure 3 The diagram shown is a schematic of the structure after the support frame has been removed. Figure 6 for Figure 3 The diagram shows the structure after the baffle is moved outward.

[0027] In the specific implementation process, such as Figures 1-6As shown, the device includes a placement rack 1, with multiple collection devices installed on the inner side of the placement rack 1. Each collection device includes a support frame 2 and a placement frame 3. The top of the support frame 2 is fixedly connected to the bottom of the placement frame 3. A rotating device is provided on the support frame 2. The top view of the placement frame 3 is square. Each of the four side walls of the placement frame 3 has an insertion hole 4. Each of the four insertion holes 4 has a movable frame 5 inserted into it. The rotating device can drive the four movable frames 5 to move outwards from the placement frame 3 at the same time. Each of the four movable frames 5 has a baffle 6 fixed at one end extending outwards from the inner cavity of the placement frame 3. The four baffles 6 can be assembled into a square structure in terms of top view by bringing them close together.

[0028] The rotating device includes a rotating component and four transmission components. All four transmission components are mounted on the placement frame 3 and connected to four movable frames 5 respectively. The rotating component is mounted on the support frame 2 and can drive the four transmission components to rotate. The rotating component includes a rotating rod 7, a driving bevel gear 8, and a handle 9. The rotating rod 7 is rotatably connected to the support frame 2, with the driving bevel gear 8 fixedly connected to the top end of the rotating rod 7 and the handle 9 fixedly connected to the bottom end. The transmission components include a vertical plate 10, a threaded rod 11, and a driven bevel gear 12. The vertical plate 10 is fixedly connected to the top of the inner cavity of the placement frame 3. The wall, the threaded rod 11 is rotatably connected to the upright plate 10, the threaded rod 11 is threadedly connected to the movable frame 5, one end of the threaded rod 11 is fixedly connected to the driven bevel gear 12, the driving bevel gear 8 meshes with the driven bevel gear 12, the throttle 9 is rotated, the throttle 9 drives the driving bevel gear 8 to rotate through the throttle rod 7, thereby causing multiple driven bevel gears 12 to rotate, and in turn causing multiple threaded rods 11 to rotate. Through the rotation of the threaded rod 11, the movable frame 5 drives the baffle 6 to move outward under the limit of the insertion hole 4, so that the garbage bag is no longer attached to the baffle 6, making it easy to take out the garbage bag;

[0029] The top two sides of the placement rack 1 are rotatably connected to rotating plates 13. The ends of the two rotating plates 13 are fixedly connected to rain covers 21. Limiting components for fixing the rotating plates 13 are also installed on both sides of the placement rack 1. The limiting components include side plates 14 and fastening bolts 15. The side plates 14 are fixedly connected to the side wall of the placement rack 1. The fastening bolts 15 are threadedly connected to the side plates 14. When the rotating plates 13 are in a vertical state, the fastening bolts 15 can be moved into the grooves opened in the rotating plates 13. Two mounting plates 16 are also fixedly connected to both sides of the placement rack 1. The two horizontal rotating plates 13 can be supported by the two mounting plates 16 respectively. When the rotating plates 13 are in a vertical state, the rain covers 21 play a role in rain protection. When the handle 9 is in a horizontal state, it provides space for lifting the garbage bag.

[0030] The four baffles 6 are also fitted with elastic rings 17. Limiting plates 18 are fixedly connected to the outer walls of the four baffles 6 near the top. After assembling the four baffles 6, the garbage bag is placed inside the four baffles 6 and the end of the garbage bag is folded over the outside of the four baffles 6. The elastic rings 17 are wrapped around the folded garbage bag. The limiting plates 18 make it difficult for the elastic rings 17 to come off the garbage bag.

[0031] The support frame 2 has an inverted U-shaped structure, and the two ends of the support frame 2 have inverted T-shaped structures. The two ends of the support frame 2 are respectively slidably set in two slide rails 19. The slide rails 19 are fixedly connected to the inner wall of the placement frame 1. The slide rails 19 and the inverted T-shaped structures at the ends of the support frame 2 facilitate the sliding of the support frame 2 on the slide rails 19.

[0032] The placement rack 1 is equipped with two opening and closing doors 20. When the two opening and closing doors 20 are closed, the limiting plate 18 on one side of the collection device is in contact with the inner wall of the placement rack 1, and the limiting plate 18 on the other side of the collection device is in contact with the side wall of the opening and closing door 20. The two opening and closing doors 20 can be locked by a rotary lock when closed. The rotary lock model can be MS816-1.

[0033] The working principle of this utility model is as follows: When changing the garbage bag, rotate the fastening bolt 15 so that one end of the fastening bolt 15 moves out of the groove of the rotating plate 13, rotate the rotating plate 13 by 90° so that the rotating plate 13 rests on the mounting plate 16, open the opening and closing door 20, and pull the collection device outward a certain distance. The end of the support frame 2 slides on the slide rail 19. By pulling a certain distance (the pulling distance here is small, only used to adapt to the outward expansion of the baffle 6, compared with pulling the collection device on the slide rail 19 a larger distance, the present application...) The structure can alleviate the problem of uneven force caused by pulling a large distance, so that the limiting plate 18 on one side of the collection device is not attached to the inner wall of the placement rack 1, leaving space for the outward expansion of the baffle 6. Remove the elastic ring 17, turn the handle 9, and the handle 9 drives the drive bevel gear 8 to rotate through the rotating rod 7, thereby causing multiple driven bevel gears 12 to rotate, which in turn causes multiple threaded rods 11 to rotate. Through the rotation of the threaded rods 11, the moving frame 5 moves the baffle 6 outward under the limitation of the insertion hole 4, so that the garbage bag is no longer attached to the baffle 6, making it easy to remove the garbage bag.

[0034] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0035] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model.
