Abstract
Description
Technical Field
[0001] This utility model relates to the field of trash can technology, and in particular to a multi-layer nested plastic trash can. Background Technology
[0002] The 240-liter plastic trash can is widely used in urban sanitation and waste sorting management, primarily for waste collection in households, businesses, and public places. This trash can holds a large amount of waste, reducing the need for frequent emptying. Made of durable plastic, it is highly corrosion-resistant and UV-resistant, adapting to various climatic conditions. Suitable for large-scale waste processing and sorting, it effectively prevents waste leakage and maintains environmental cleanliness.
[0003] A typical 240mm plastic trash can consists of several parts, including the body, lid, wheels, and handle. The body is made of high-strength plastic (such as polyethylene), making it durable and impact-resistant. The lid is designed to open and close, helping to seal the trash and prevent odor leakage. The wheels are designed for easy movement, especially useful for sanitation workers during garbage collection in cities or communities. The handles are located on both sides of the can for easy carrying and emptying.
[0004] Traditional 240mm plastic trash cans, lacking a tightly connected structure, are too shapely and surface-flat for stacking or linking. During transport, the gaps between the cans occupy significant space, leading to low efficiency and increased costs. Furthermore, the lack of a stable connection mechanism makes multiple cans prone to rolling or tilting when stacked, increasing instability and the risk of damage during transport. This inconvenience also necessitates more space for management and storage, hindering efficient stacking and organization. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a multi-layer nested plastic trash can, which aims to improve the problem that traditional plastic 240 trash cans are prone to rolling or tilting due to the lack of a stable connection mechanism, which increases instability and damage during transportation.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a multi-layer nested plastic trash can, including a can body, a plurality of insert rings fixedly connected to the side wall of the can body, each insert ring having a slot inside, a plurality of fixed cylinders fixedly connected to the side wall of the can body, and a connecting component being provided inside the fixed cylinder;
[0007] The connecting assembly includes a fixed shaft, which is fixedly connected inside each of the fixed cylinders. Multiple slip rings are slidably connected to the outer wall of the fixed shaft. Multiple springs are sleeved on the outer wall of the fixed shaft, with one end of each spring fixedly connected inside the fixed shaft and the other end fixedly connected inside the fixed cylinder. A connecting rod is rotatably connected to the side wall of each slip ring. A side plate is provided inside the fixed cylinder, with one end of each connecting rod rotatably connected to the side wall of the side plate. A retaining plate is fixedly connected to the side wall of the side plate and slidably connected inside the retaining groove. An opening and closing assembly is provided at the top of the cylinder.
[0008] Furthermore, the opening and closing assembly includes a lid, which is disposed on the top of the barrel body.
[0009] Furthermore, a fixing post is fixedly connected to the side wall of the bucket lid, and multiple fixing parts are fixedly connected to the top of the bucket body.
[0010] Furthermore, the fastener has multiple connecting shafts fixedly connected inside, and each connecting shaft has a rotating plate rotatably connected to its outer wall.
[0011] Furthermore, each of the rotating plates has a circular groove inside, and the fixing column is slidably connected inside the circular groove.
[0012] Furthermore, each of the circular groove sidewalls is fixedly connected to a side platform, and an inner shaft is fixedly connected inside the side platform.
[0013] Furthermore, a telescopic rod is provided between the side platforms, and the two ends of the telescopic rod are respectively rotatably connected to the outer wall of the multiple inner shafts.
[0014] Furthermore, a tension spring is fitted on the outer wall of the telescopic rod, and the two ends of the tension spring are respectively fixedly connected to the two ends of the telescopic rod.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the slot of one trash can is first inserted into the insertion ring of another trash can. The wedge-shaped surface of the card plate will automatically retract. Finally, the elastic force of multiple springs pushes the slip ring to make the card plate lock in the slot. This allows multiple trash cans to be transported at once without the need to handle each trash can individually. This reduces the time, labor and cost required during transportation and improves logistics and transportation efficiency.
[0017] 2. In this utility model, the rotating plate can rotate on the outer wall of the connecting shaft after being subjected to force. Finally, the included angle of the circular groove inside the rotating plate expands, which allows the fixing column to be disassembled. When reinstalled, it is kept stable by the tension spring. The nestable trash cans can be nested together when not in use, reducing the volume occupied and effectively saving limited storage space. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] Reference Figures 1-2 The present invention provides an embodiment of a multi-layer nested plastic trash can, including a can body 1, a plurality of insert rings 2 fixedly connected to the side wall of the can body 1, each insert ring 2 having a slot 3 inside, and a plurality of fixed cylinders 4 fixedly connected to the side wall of the can body 1, with a connecting component inside the fixed cylinder 4.
[0025] The connecting assembly includes a fixed shaft 5, which is fixedly connected inside each fixed cylinder 4. Multiple slip rings 6 are slidably connected to the outer wall of the fixed shaft 5. Multiple springs 7 are sleeved on the outer wall of the fixed shaft 5. One end of the spring 7 is fixedly connected inside the fixed shaft 5, and the other end of the spring 7 is fixedly connected inside the fixed cylinder 4. A connecting rod 8 is rotatably connected to the side wall of each slip ring 6. A side plate 9 is provided inside the fixed cylinder 4. One end of each connecting rod 8 is rotatably connected to the side wall of the side plate 9. A clamping plate 10 is fixedly connected to the side wall of the side plate 9. The clamping plate 10 is slidably connected inside the clamping groove 3. An opening and closing assembly is provided on the top of the cylinder 1.
[0026] Specifically, firstly, when connecting multiple bins 1 to each other, the slot 3 of one bin needs to be inserted into the ring 2 of another bin. At this time, the wedge-shaped surface of the locking plate 10 will automatically retract, causing the side plate 9 to move inside the fixed cylinder 4, thereby causing multiple connecting rods 8 to rotate and change their tilt angle. Subsequently, when the locking plate 10 enters the predetermined position of the slot 3, the elastic force of multiple springs 7 pushes the slip ring 6, so that the locking plate 10 is firmly locked inside the slot 3, ensuring a stable connection between the bins. In this way, multiple bins can be transported together without the need to handle each bin individually. This design effectively reduces the time, labor and cost required during transportation, thereby improving logistics and transportation efficiency.
[0027] Reference Figure 3 The opening and closing assembly includes a bucket lid 11, which is located on the top of the bucket body 1. A fixing post 12 is fixedly connected to the side wall of the bucket lid 11. Multiple fixing parts 13 are fixedly connected to the top of the bucket body 1. Multiple connecting shafts 14 are fixedly connected inside the fixing parts 13. A rotating plate 15 is rotatably connected to the outer wall of each connecting shaft 14. A circular groove 16 is opened inside each rotating plate 15. The fixing post 12 is slidably connected inside the circular groove 16. A side platform 17 is fixedly connected to the side wall of each circular groove 16. An inner shaft 18 is fixedly connected inside the side platform 17. A telescopic rod 19 is arranged between the side platforms 17. The two ends of the telescopic rod 19 are rotatably connected to the outer walls of the multiple inner shafts 18. A tension spring 20 is sleeved on the outer wall of the telescopic rod 19. The two ends of the tension spring 20 are fixedly connected to the two ends of the telescopic rod 19.
[0028] Specifically, when it is necessary to disassemble the lid 11 and nest multiple barrels 1 together, first pull the rotating plate 15. After being subjected to force, the rotating plate 15 will rotate around the outer wall of the connecting shaft 14, and at the same time drive the side platform 17 of its side wall to move synchronously, thereby driving the telescopic rod 19 to extend. At this time, the included angle of the circular groove 16 inside the rotating plate 15 gradually expands, which can smoothly disassemble the fixing column 12. When reinstalling, the stability of the lid 11 is maintained by the action of the tension spring 20. When not in use, they can be nested together, thereby reducing the space occupied, effectively saving limited storage space, and improving the overall space utilization rate.
[0029] Working principle: When connecting multiple bins 1 together, insert the slot 3 of one bin into the ring 2 of another bin. The wedge-shaped surface of the locking plate 10 will automatically retract, causing the side plate 9 to move inside the fixed cylinder 4 and causing the multiple connecting rods 8 to rotate and change their tilt angle. Then, when the locking plate 10 enters the slot 3, the elastic force of the multiple springs 7 pushes the slip ring 6 to lock the locking plate 10 inside the slot 3. This allows multiple bins to be transported at once without the need to handle each bin individually, reducing the time and manpower required during transportation. This reduces labor and costs, improves logistics and transportation efficiency. When it is necessary to disassemble the lid 11 and nest multiple bins 1 together, pull the rotating plate 15. After the rotating plate 15 is subjected to force, it can rotate on the outer wall of the connecting shaft 14 and drive the side platform 17 of its side wall to move synchronously, causing the telescopic rod 19 to extend. At this time, the included angle of the circular groove 16 inside the rotating plate 15 expands, so the fixing column 12 can be disassembled. When reinstalled, it is kept stable by the tension spring 20. The nestable trash cans can be nested together when not in use, reducing the volume occupied and effectively saving limited storage space.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
