Description
Technical Field
[0001] This utility model relates to the technical field of lifting support devices, and in particular to a novel underground lifting support device. Background Technology
[0002] With the acceleration of urbanization, the drawbacks of traditional surface-mounted garbage bins have become increasingly apparent. On the one hand, they occupy a large amount of public space such as sidewalks and streets, obstructing pedestrian traffic, especially in densely populated areas, often causing traffic congestion and inconvenience. On the other hand, garbage left in the open emits odors, breeds mosquitoes, flies, and bacteria, seriously affecting the surrounding environmental sanitation and causing great inconvenience to residents. Moreover, ordinary garbage bins have a simple appearance and are inconsistent with urban landscape planning. Against this backdrop, underground garbage bins have emerged. They hide the bin underground, leaving only the disposal opening on the ground, which saves ground space, optimizes the use of urban roads, and effectively isolates odors and reduces bacterial growth through a closed design.
[0003] However, traditional underground trash cans require users to bend over to lift the lid before throwing the trash into the bin, which is inconvenient. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a new type of underground lifting support device, which aims to improve the problem that users need to bend over to lift the cover and then throw the garbage into the garbage can, which is inconvenient to use.
[0005] To achieve the above objectives, this utility model provides the following technical solution: A novel underground lifting support device includes a pre-embedded frame, a connecting plate slidably connected to the inner wall of the pre-embedded frame, a double-headed motor provided on the middle inner wall of the connecting plate, threaded rods provided at the output ends of the double-headed motors, a baffle plate rotatably connected to the outer wall of the threaded rod, the lower surface of the baffle plate rotatably connected to both sides of the upper surface of the connecting plate, a threaded block threadedly connected to the outer wall of the threaded rod, a rotating column rotatably connected to the outer wall of the threaded block, a support rod rotatably connected to the outer wall of the rotating column, a second baffle plate rotatably connected to the inside of the support rod, a garbage bin rotatably connected to the upper surface of the second baffle plate, and a limit component provided on the outer wall of the garbage bin for limiting the direction of movement of the garbage bin.
[0006] Preferably, the limiting component includes a limiting post, the outer wall of which is slidably connected to the inner wall of the trash can, the outer wall of the trash can has a limiting groove, the outer wall of the limiting post is slidably connected to the inner wall of the limiting groove, and the outer wall of the limiting post is provided with a fixing rod, the upper surface of which is fixedly connected to the outer wall of the pre-embedded frame.
[0007] Preferably, the inner wall of the pre-embedded frame is provided with a load-bearing plate, and a spring is provided inside the left side of the load-bearing plate.
[0008] Preferably, the outer wall of the spring is fixedly connected to a bracket, and the outer wall of the bracket is slidably connected inside the limiting post.
[0009] Preferably, a connecting rod is fixedly connected to the outer wall of the first bracket, and a second bracket is fixedly connected to the outer wall of the first connecting rod.
[0010] Preferably, the upper surface of the second bracket is fixedly connected to the lower right surface of the connecting plate, and a sliding bracket is slidably connected to the inner left side of the connecting plate.
[0011] Preferably, a second connecting rod is fixedly connected to the outer wall of the sliding bracket, and a third bracket is fixedly connected to the outer wall of the second connecting rod.
[0012] Preferably, the lower surface of the bracket three is fixedly connected to the upper right surface of the load-bearing plate.
[0013] This utility model has the following beneficial effects:
[0014] 1. In this utility model, the dual-head motor drives the threaded rods on both sides to rotate synchronously, the threaded blocks move towards the middle, causing the rotating column to move, which in turn causes the support rod to move. Since the length of the support rod is fixed, the rotating column will also cause the support rod to rotate when it pushes, and the lifting baffle will move upward, thereby raising the trash can and making it convenient for users to throw away trash.
[0015] 2. In this utility model, when a user throws garbage into the trash can, the impact force generated by the garbage presses down on the connecting plate, causing the second bracket and the sliding bracket to move down. The second bracket pushes the first connecting rod to rotate, which moves the first bracket and squeezes the spring to buffer the impact force. The sliding bracket drives the second connecting rod to rotate, making it move smoothly and ensuring that the connecting plate moves down horizontally. As the amount of garbage increases, the length of the trash can exposed above the ground decreases, which can prevent damage to parts and determine whether the trash can is full.

Detailed Implementation
[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0023] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a novel underground lifting support device, comprising a pre-embedded frame 1, a connecting plate 2 slidably connected to the inner wall of the pre-embedded frame 1, a double-headed motor 3 provided on the middle inner wall of the connecting plate 2, threaded rods 4 provided at the output ends of the double-headed motors 3, a baffle 5 rotatably connected to the outer wall of the threaded rod 4, the lower surface of the baffle 5 fixedly connected to both sides of the upper surface of the connecting plate 2, a threaded block 6 threadedly connected to the outer wall of the threaded rod 4, a rotating column 7 rotatably connected to the outer wall of the threaded block 6, a support rod 8 fixedly connected to the outer wall of the rotating column 7, a second baffle 9 rotatably connected inside the support rod 8, a garbage bin 10 fixedly connected to the upper surface of the second baffle 9, and a limit component provided on the outer wall of the garbage bin 10 for limiting the movement direction of the garbage bin 10.
[0024] Specifically, the dual-head motor 3 is activated to drive the threaded rods 4 on both sides to rotate synchronously. Since the threads of the threaded rods 4 on both sides rotate in opposite directions, the threaded blocks 6 will move towards the center position under the action of the threads. The baffle 5 limits the position of the threaded rods 4, ensuring that they can only rotate stably around their own axis without deviation or shaking. The lower surface of the threaded block 6 is in contact with the upper surface of the connecting plate 2, so that the threaded rods 4 can move stably towards the center, thereby driving the rotating columns 7 on both sides to move synchronously. The movement of the rotating columns 7 causes the support rod 8 to move. Since the length of the support rod 8 is fixed, when the rotating column 7 pushes the support rod 8 to move, the support rod 8 will start to rotate around the connection point with the rotating column 7 as the axis, thereby lifting the baffle 9 and pushing the baffle 9 to move upward, causing the garbage bin 10 to rise, thus making it easier to lift the garbage bin 10 for support and making it convenient for users to throw away garbage.
[0025] Reference Figure 1and Figure 3 The limiting component includes a limiting post 13, the outer wall of the limiting post 13 is slidably connected to the inner wall of the garbage bin 10, the outer wall of the garbage bin 10 is provided with a limiting groove 11, the outer wall of the limiting post 13 is slidably connected to the inner wall of the limiting groove 11, and the outer wall of the limiting post 13 is provided with a fixing rod 12, the upper surface of the fixing rod 12 is fixedly connected to the outer wall of the pre-embedded frame 1.
[0026] Specifically, during the movement of the trash can 10, the limiting post 13 will move synchronously in the limiting groove 11, further ensuring the directionality of the movement of the trash can 10 and preventing it from tilting to either side.
[0027] Reference Figure 1 and Figure 4 The inner wall of the pre-embedded frame 1 is provided with a load-bearing plate 14, and a spring 15 is provided inside the left side of the load-bearing plate 14. A bracket 16 is fixedly connected to the outer wall of the spring 15, and the outer wall of the bracket 16 is slidably connected to the inside of the limiting post 13. A connecting rod 17 is fixedly connected to the outer wall of the bracket 16, and a bracket 28 is fixedly connected to the outer wall of the connecting rod 17. The upper surface of the bracket 28 is fixedly connected to the lower right surface of the connecting plate 2, and a sliding bracket 19 is slidably connected to the inner left side of the connecting plate 2. A connecting rod 20 is fixedly connected to the outer wall of the sliding bracket 19, and a bracket 31 is fixedly connected to the outer wall of the connecting rod 20. The lower surface of the bracket 321 is fixedly connected to the upper right surface of the load-bearing plate 14.
[0028] Specifically, when a user throws trash into the trash can 10, the trash, due to its own weight and the inertia of being thrown, exerts a downward impact force on the trash can 10, which in turn presses down on the connecting plate 2, causing the second bracket 18 and the sliding bracket 19 to move downward. When the second bracket 18 moves downward, it generates a pushing force on the first connecting rod 17. Since the length of the first connecting rod 17 is fixed, it causes the first connecting rod 17 to rotate, thereby pushing the first bracket 16 to move. At the same time, it also compresses the spring 15, causing the spring 15 to gradually compress and deform, thus buffering part of the impact force. Furthermore, the downward movement of the sliding bracket 19 also causes the second connecting rod 20 to rotate. The bracket 21 is fixed to the upper surface of the load-bearing plate 14, so that the sliding bracket 19 can move smoothly inside the connecting plate 2. This ensures that the connecting plate 2 always maintains a horizontal downward movement, avoiding tilting or jamming. As the garbage inside the garbage bin 10 continues to accumulate, the length of the garbage bin 10 protruding above the ground will gradually decrease, thereby effectively reducing the impact force on the garbage bin 10 when throwing garbage, preventing internal parts from being damaged by violent impact. In addition, users can also intuitively judge whether the garbage bin 10 is full by observing the change in the length of the garbage bin 10 protruding above the ground, so as to clean it in time.
[0029] Working principle: When the device is needed, the double-headed motor 3 is started. The double-headed motor 3 drives the threaded rods 4 on both sides to rotate. Since the threaded rods 4 on both sides are set with reverse threads, the threaded blocks 6 on both sides move towards the center. The baffle 5 supports and restricts the position of the threaded rods 4, and the lower surface of the threaded block 6 is in contact with the upper surface of the connecting plate 2, so that the threaded block 6 will only move towards the center and will not rotate. This drives the rotating columns 7 on both sides to move. The movement of the rotating columns 7 drives the support rod 8 to move. Since the length of the support rod 8 is constant, while the rotating columns 7 drive the support rod 8 to move, it will cause the support rod 8 to move. The rod 8 rotates, which in turn lifts the baffle 9. The movement of the baffle 9 causes the garbage bin 10 to move. When the garbage bin 10 moves, the limiting post 13 moves inside the limiting groove 11, further ensuring the direction of movement of the garbage bin 10 and preventing it from tilting to the sides. The pre-embedded frame 1 and the fixing rod 12 support and fix the limiting post 13, thereby facilitating the lifting of the garbage bin 10 for support and making it convenient for users to dispose of garbage. When a user throws garbage into the garbage bin 10, the garbage will exert an impact force on the garbage bin 10, which will then press down on the connecting plate 2, promoting... The connecting plate 2 presses down on the second bracket 18 and the sliding bracket 19. When the second bracket 18 moves downward, it pushes the first connecting rod 17 to move. Since the length of the first connecting rod 17 is fixed, it rotates and pushes the first bracket 16 to move. As the first bracket 16 moves inside the load-bearing plate 14, it also compresses the spring 15. At the same time, the downward movement of the sliding bracket 19 also drives the second connecting rod 20 to rotate. Since the third bracket 21 is fixed to the upper surface of the load-bearing plate 14, the thrust is applied to the sliding bracket 19, causing the sliding bracket 19 to move inside the connecting plate 2, ensuring that the connecting plate 2... The device moves horizontally downwards, and the more trash inside the trash can 10, the shorter the length of the trash can 10 protruding above the ground. This reduces the impact of throwing trash on the trash can 10, preventing damage to internal parts, and also allows users to observe whether the trash can 10 is full. In other words, the device not only makes it easy to lift the trash can 10 for support, making it convenient for users to throw away trash, but also reduces the impact of throwing trash on the trash can 10, preventing damage to internal parts, and allows users to observe whether the trash can 10 is full.
