Abstract
Description
Technical Field
[0001] This utility model belongs to the field of garbage bin structural design technology, specifically relating to a linkage transmission mechanism for a garbage sorting bin. Background Technology
[0002] With urban planning, environmental beautification has become an important aspect. Garbage bins are installed on various roads throughout the city to facilitate waste collection and management, and prevent environmental pollution. Currently, most common garbage sorting bins use traditional linkage transmission structures to control the opening and closing of the lids. However, existing mechanisms generally suffer from slow lid opening speeds and transmission lag when dealing with high-frequency disposal needs, resulting in long waiting times for users. This is especially problematic in densely populated areas, leading to low disposal efficiency. Therefore, we provide a linkage transmission mechanism for garbage sorting bins to solve these problems. Utility Model Content
[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a linkage transmission mechanism for waste sorting bins.
[0004] To achieve the above objectives, this utility model provides the following technical solution:
[0005] A linkage transmission mechanism for a waste sorting bin includes an outer casing, an inner movable groove 1 inside the outer casing, a second movable groove 2 inside the inner wall of the first movable groove 1, the second movable groove 2 extending to the outer surface of the outer casing, a linkage assembly inside the first movable groove 1, a lifting assembly inside the first movable groove 1, a set of guide grooves inside the inner wall of the outer casing, an inner casing fixedly connected to the inner wall of the outer casing, and a lid rotatably connected to the top of the outer casing.
[0006] As a preferred embodiment, the linkage assembly includes a connecting plate fixedly connected to the outer surface of the outer casing, an elastic element fixedly connected to the upper surface of the connecting plate, and a foot pedal fixedly connected to the end of the elastic element away from the connecting plate.

[0009] As a preferred embodiment, a set of connecting rods is fixedly connected to the outer surface of the rotating shaft, and a top plate is fixedly connected to the end of the connecting rods away from the rotating shaft.
[0010] As a preferred embodiment, the lifting assembly includes an H-shaped frame slidably connected to the outer surface of the inner box, with a set of balls embedded at the upper and lower ends of the H-shaped frame, and the outer surface of the balls being rotatably connected to the inner wall of the H-shaped frame.
[0011] In a preferred embodiment, one set of balls contacts the bottom of the lid, and the other set of balls contacts the top of the top plate.
[0012] As a preferred embodiment, a set of guide plates is fixedly connected to the outer surface of the H-shaped frame, and the outer surface of the guide plates is slidably connected to the inner wall of the guide groove.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] (1) Through the linkage design in the linkage assembly, this utility model can drive the lifting assembly to move up quickly. Through the rapidly moving lifting assembly, the stepping stroke in the linkage assembly can be quickly converted into the power for the rapid flipping of the lid, which significantly improves the opening speed of the lid.

Detailed Implementation
[0021] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.
[0022] Please see Figures 1 to 4 As shown, this embodiment of the utility model provides a linkage transmission mechanism for a waste sorting bin, specifically including an outer box 1. An movable groove 2 is provided inside the outer box 1. The height and width of the movable groove 2 can be designed according to the maximum swing amplitude of the linkage assembly 4 and the lifting stroke of the lifting assembly 5, ensuring that the connecting rod 407 and the H-shaped frame 501 do not interfere with the groove wall during movement. A movable groove 3 is provided on the inner wall of the movable groove 2, extending through to the outer surface of the outer box 1. The movable groove 3 is a transverse groove connecting the inside and outside of the outer box 1, and its position corresponds to the installation height of the foot pedal 403, providing movement space for the foot pedal 403 and the connecting frame 404. A set of guide grooves 6 are provided on the inner wall of the outer box 1. The guide grooves 6 are longitudinal grooves opened on the inner wall of the outer box 1. The number of them corresponds to the guide plate 503. They are usually two symmetrically distributed. The depth of the groove is adapted to the thickness of the guide plate 503 to form a sliding pair structure. The H-shaped frame 501 is forced to move in the vertical direction by mechanical limit, while absorbing the lateral force in the transmission process to ensure the movement accuracy of the lifting component 5.
[0023] Please see Figures 1 to 4 As shown, an inner box 7 is fixedly connected to the inner wall of the outer box 1. The inner box 7 is fixed to the inner wall of the outer box 1 and serves as the garbage storage cavity of the garbage sorting bin. Its outer surface provides a sliding guide rail for the H-shaped frame 501 of the lifting component 5. The height of the inner box 7 matches that of the outer box 1. When the top opening is closed with the lid 8, a sealed structure is formed to prevent odor from escaping. The lid 8 is rotatably connected to the top of the outer box 1. The lid 8 is connected to the top of the outer box 1 through a rotating shaft and can be flipped upward around the shaft to open. Its bottom contacts the upper end ball bearing 502 of the lifting component 5. When the H-shaped frame 501 moves upward, the ball bearing 502 pushes the bottom edge of the lid 8, using the lever principle to make the lid 8 open quickly. When the H-shaped frame 501 moves downward, the lid 8 closes smoothly under the action of gravity, realizing the automatic opening and closing of the garbage disposal opening.
[0024] Please see Figures 1 to 4As shown, the interior of the movable slot 2 is equipped with a linkage assembly 4, which is the core structure for force transmission. The linkage assembly 4 consists of a connecting plate 401, an elastic element 402, a foot pedal 403, a connecting frame 404, a rotating shaft 405, a limiting seat 406, a connecting rod 407, and a top plate 408. The linkage assembly 4 includes a connecting plate 401 fixedly connected to the outer surface of the outer casing 1, serving as the lower support for the elastic element 402. It is connected to the outer casing 1 by bolts or welding to ensure no displacement occurs under stress. An elastic element 402, preferably a coil spring or elastic rubber column, is fixedly connected to the upper surface of the connecting plate 401. Its lower end is fixed to the connecting plate 401, and its upper end is connected to the foot pedal 403, which absorbs the stepping force and stores elastic potential energy, while providing a restoring force when the pedal is released. The end of the elastic element 402 away from the connecting plate 401 is fixedly connected to the foot pedal 403, which is suspended outside the outer box 1 by the elastic element 402. Its surface is provided with anti-slip texture, and its bottom surface is fixedly connected to the rotating shaft 405 through the connecting frame 404 to form the input end of the lever transmission.
[0025] Please see Figures 1 to 4 As shown, a connecting frame 404 is fixedly connected to the bottom surface of the foot pedal 403. One end of the connecting frame 404 is fixed to the center of the bottom surface of the foot pedal 403, and the other end is connected to the rotating shaft 405, converting the up-and-down movement of the foot pedal 403 into the rotational movement of the rotating shaft 405. The end of the connecting frame 404 away from the foot pedal 403 is fixedly connected to the rotating shaft 405, which is horizontally installed in the bearing of the limiting seat 406 and can rotate freely around the axis. The connecting rod 407 fixed on its outer surface swings synchronously with the rotating shaft 405 to push the top plate 408 up and down. The outer surface of the rotating shaft 405 is rotatably connected to the limiting seat 406. The bottom surface of the limiting seat 406 is fixedly connected to the inner wall of the movable groove 2, and a bearing is embedded inside to provide a stable rotation fulcrum for the rotating shaft 405 and at the same time restrict the axial movement of the rotating shaft 405. A set of connecting rods 407 are fixedly connected to the outer surface of the rotating shaft 405. These are three equally spaced rod-shaped structures, one end of which is fixed to the outer surface of the rotating shaft 405, and the other end is connected to the top plate 408, forming a fan-shaped transmission trajectory to amplify the rotation amplitude of the rotating shaft 405. The end of the connecting rod 407 away from the rotating shaft 405 is fixedly connected to the top plate 408, which is a horizontally set rectangular plate. Its upper surface contacts the ball bearings 502 of the lifting assembly 5. The connecting rods 407 push the rods to achieve vertical translation, converting the rotational motion of the rotating shaft 405 into the linear motion of the lifting assembly 5.
[0026] Please see Figures 1 to 4As shown, the interior of the movable slot 2 is equipped with a lifting assembly 5, which is the actuator for driving the opening of the box cover 8. The lifting assembly 5 consists of an H-shaped frame 501, ball bearings 502, and a guide plate 503. The lifting assembly 5 includes an H-shaped frame 501 that is slidably connected to the outer surface of the inner box 7. It has an H-shaped frame structure, with ball bearings 502 embedded at its upper and lower ends. The lower ball bearing 502 contacts the top plate 408, and the upper ball bearing 502 contacts the bottom of the box cover 8. The rolling friction of the ball bearings 502 reduces the transmission resistance. A set of ball bearings 502 is embedded at the upper and lower ends of the H-shaped frame 501. The outer surface of the ball bearings 502 is rotatably connected to the inner wall of the H-shaped frame 501. One set of ball bearings 502 contacts the bottom of the box cover 8, and the other set of ball bearings 502 contacts the top of the top plate 408. The ball bearings 502 are standard ball bearings made of stainless steel and are embedded in the upper and lower end grooves of the H-shaped frame 501. They can rotate freely. The lower ball bearing 502 receives the thrust of the top plate 408 and converts it into the upward moving force of the H-shaped frame 501. The upper ball bearing 502 pushes the box cover 8 to rotate around the top rotation axis of the outer box 1, thereby opening the box cover 8. A set of guide plates 503 are fixedly connected to the outer surface of the H-shaped frame 501. The outer surface of the guide plates 503 is slidably connected to the inner wall of the guide groove 6. The guide plates 503 are two symmetrically arranged strip plates fixed on both sides of the H-shaped frame 501. Their outer surfaces are slidably engaged with the guide groove 6 on the inner wall of the outer box 1. The cross-sectional shape of the guide plates 503 matches the guide groove 6 to ensure that the H-shaped frame 501 maintains vertical movement during lifting and lowering, and avoids tilting or jamming.
[0027] In use, the user steps on the foot pedal 403, which drives the rotating shaft 405 to rotate around the limiting seat 406 via the connecting frame 404. At this time, the elastic element 402 is compressed and stores energy. Simultaneously, the connecting rod 407 on the rotating shaft 405 pushes the top plate 408 upward. The top plate 408 drives the H-shaped frame 501 to slide upward along the outer surface of the inner box 7 via the ball bearings 502 in contact with the top. The guide plates 503 on both sides of the H-shaped frame 501 slide synchronously in the guide grooves 6 to ensure movement stability. Another set of ball bearings 502 at the top of the frame 501 pushes the lid 8 to open around the rotating shaft at the top of the outer box 1. When the user releases the foot pedal 403, the elastic element 402 releases potential energy to drive the rotating shaft 405 to rotate in the opposite direction, causing the connecting rod 407 and the top plate 408 to reset. Under the action of gravity, the H-shaped frame 501 slides down along the inner box 7. The ball bearings 502, together with the guide plate 503, guide the lid 8 to close smoothly, thereby realizing the rapid opening and closing of the lid 8 and the automatic reset of the pedal through the linkage of the connecting rod assembly 4 and the lifting assembly 5.
[0028] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
