Description

Technical Field

[0001] This utility model relates to the field of trash can technology, and in particular to a foot-operated flip-top mechanism for trash cans based on brake cable transmission. Background Technology

[0002] Most mainstream foot-operated trash cans on the market currently use a single-link transmission structure or a simple spring reset device, but the following technical bottlenecks still exist: In the single-link structure, the foot pedal force needs to be transmitted to the lid through a single link, resulting in insufficient opening angle (usually ≤50°), making it difficult to dispose of large-volume garbage. To address this, the industry has attempted to optimize the structure by adding an auxiliary link to increase the opening angle, but this increases the structural complexity and manufacturing costs. Although the industry has tried to optimize the structure by upgrading materials (such as stainless steel) or improving the structure (such as multi-link), this often comes at the cost of cost. Therefore, there is an urgent need for a foot-operated flip-top mechanism that is structurally simple, has efficient force transmission, and is highly adaptable to the environment to overcome the limitations of the existing technology. To this end, this application proposes a foot-operated flip-top mechanism for trash cans based on brake line transmission. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foot-operated flip-top mechanism for trash cans based on brake line drive.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A foot-operated flip-top mechanism for a trash can based on brake cable drive includes a main body mounted on the trash can shell. A top cover is rotatably mounted on the rear top side of the trash can shell, and multiple support legs are mounted on the bottom of the trash can shell. Wheels are rotatably mounted on the bottom ends of the support legs. The main body of the foot-operated flip-top mechanism includes:

[0006] A foot pedal is located at the bottom of the trash can casing;

[0007] The fixed sheet metal has a U-shaped structure and is installed on the rear side of the foot pedal and slidably installed between the two support legs on the front side;

[0008] A flexible drive mechanism is installed between the fixed sheet metal and the bottom of the trash can shell. The flexible drive mechanism is used to drive the fixed sheet metal vertically.

[0009] There are two brake cables, the bottom of which is fixedly connected to the top of the fixed sheet metal. When the fixed sheet metal moves down, it can pull both brake cables at the same time.

[0010] The flip-top squeezing mechanism consists of two sets, installed on the top of both sides of the trash can shell and in contact with the bottom of the top cover. The brake cable is connected to the corresponding flip-top squeezing mechanism. The flip-top squeezing mechanism is used to flip the top cover, and the brake cable is used to drive the flip-top squeezing mechanism.

[0011] Preferably, the elastic drive mechanism includes two return springs suspended on the top of the fixed sheet metal, and connecting blocks are fixedly connected to both sides of the bottom of the trash can shell. The return springs are suspended at the bottom of the corresponding connecting blocks. When the return springs are in a stretched state and the stepping force is released, the fixed sheet metal can be driven to move back to its original position.

[0012] Preferably, the flip-top squeezing mechanism includes two rotating shafts, which are respectively rotatably embedded in the top of both sides of the trash can shell. An inclined lever is fixedly sleeved on the rotating shaft. The bottom of the lever is inclined downward, and a roller is rotatably installed on the top of the lever. The two rollers are in movable contact with the bottom of both sides of the top cover. The rotation of the lever can drive the rollers to squeeze the top cover. Support shafts are fixedly connected to both sides of the trash can shell. The top of the support shaft is in movable contact with the bottom of the corresponding lever. The sides of the two levers that are far apart from each other are fixedly installed with the corresponding brake lines. The support shafts are used to restrict the bottom of the corresponding levers to prevent the levers from rotating forward.

[0013] Preferably, each of the two levers is fixedly connected to a connector on the side that is far apart from each other, and the bottom of the connector is fixedly connected to the top of the corresponding brake line.

[0014] Preferably, slide rails are embedded and fixed on the side of the two support legs located at the front that are close to each other, and T-shaped slide grooves are opened on both sides of the fixed sheet metal. The T-shaped slide grooves are slidably connected with the corresponding slide rails, and the slide rails play a vertical guiding role for the fixed sheet metal.

[0015] Preferably, positioning sleeves are fixedly installed on both sides of the trash can shell, and flexible protective sleeves are embedded and fixed inside the positioning sleeves. The flexible protective sleeves are movably sleeved on the corresponding brake lines, and the bottom end of the flexible protective sleeves is embedded and fixed to the bottom of the outer side of the trash can shell. The flexible protective sleeves are used to protect the corresponding brake lines.

[0016] Preferably, bearings are embedded and fixed on the top of both sides of the trash can shell, and the inner side of the inner ring of the bearing is fixedly connected to the outer side of the corresponding rotating shaft, so that the bearing can be used to rotate the corresponding rotating shaft.

[0017] Compared with existing technologies, the beneficial effects of this utility model are:

[0018] By combining the foot pedal, fixed sheet metal, elastic drive mechanism, brake cable and flip cover extrusion, the two-point drive flip cover operation can be completed by the pull of the two brake cables and the extrusion of the lever and roller when the foot is pressed. At this time, the flip cover opening angle is larger than the opening angle transmitted by a single linkage, and the lightweight design of the brake cable can achieve efficient force transmission.

[0019] This utility model, through a series of structural designs, enables two-point drive flip-top operation. In this flip-top method, the opening angle of the top cover is larger than that transmitted by a single linkage. Furthermore, the lightweight design of the brake line enables efficient force transmission, solving the problem of the bulky and complex structure of traditional trash can foot pedal mechanisms. Moreover, the overall structure is simple, and the manufacturing cost is significantly reduced compared to existing technologies, combining technological innovation with market application value.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figure 1-3A foot-operated flip-top mechanism for a trash can based on brake cable transmission includes a main body mounted on a trash can shell 4. A top cover 6 is rotatably mounted on the rear top of the trash can shell 4. The rotatable mounting method of the top cover 6 to the trash can shell 4 is the existing method for rotating trash can lids, which is not described in detail here. The inner top wall of the top of the top cover 6 is in contact with the top of the trash can shell 4. Multiple support legs 15 are mounted on the bottom of the trash can shell 4, and wheels are rotatably mounted on the bottom ends of the support legs 15. The main body of the foot-operated flip-top mechanism includes:

[0026] Foot pedal 1 is located below the trash can shell 4;

[0027] The fixed sheet metal 10 has a U-shaped structure and is installed on the rear side of the foot pedal 1 and slidably installed between the two support legs 15 on the front side. The two support legs 15 on the front side are fitted with slide rails 2 on their respective sides. T-shaped slide grooves are provided on both sides of the fixed sheet metal 10. The T-shaped slide grooves are slidably connected to the corresponding slide rails 2. The slide rails 2 provide a vertical guiding effect for the fixed sheet metal 10.

[0028] An elastic drive mechanism is installed between the bottom of the fixed sheet metal 10 and the bottom of the trash can shell 4. The elastic drive mechanism includes two return springs 12 suspended on the top of the fixed sheet metal 10. The top two sides of the fixed sheet metal 10 are fixedly connected to the first suspension rings. The bottom of the return spring 12 is suspended on the first suspension rings. The bottom two sides of the trash can shell 4 are fixedly connected to the connecting blocks 13. The return spring 12 is suspended on the bottom of the corresponding connecting blocks 13. The bottom of the connecting blocks 13 is fixedly connected to the second suspension rings. The top of the return spring 12 is suspended on the second suspension rings. When the return spring 12 is in a stretched state and the stepping force is released, it can drive the fixed sheet metal 10 to move back to its original position.

[0029] There are two brake lines 3, the bottom of which are fixedly connected to the top of the fixed sheet metal 10. When the fixed sheet metal 10 moves down, it can pull the two brake lines 3 at the same time. Positioning sleeves 14 are fixedly installed on both sides of the trash can shell 4. Flexible protective sleeves 5 are embedded and fixed inside the positioning sleeves 14. The flexible protective sleeves 5 are movably sleeved on the corresponding brake lines 3. The bottom of the flexible protective sleeves 5 is embedded and fixed to the bottom of the outer side of the trash can shell 4. The flexible protective sleeves 5 are used to protect the corresponding brake lines 3.

[0030] The flip-top squeezing mechanism consists of two sets, installed on the top sides of the garbage can shell 4 and in movable contact with the bottom of the upper cover 6. A brake line 3 is connected to the corresponding flip-top squeezing mechanism. Each flip-top squeezing mechanism includes two rotating shafts 9, which are rotatably mounted on the top sides of the garbage can shell 4. Bearings are fixedly mounted on the top sides of both sides of the garbage can shell 4, with the inner ring of the bearing fixedly connected to the outer side of the corresponding rotating shaft 9. The bearings provide a means for the rotating shaft 9 to rotate. An inclined lever 8 is fixedly fitted onto each rotating shaft 9, with its bottom inclined downwards and a roller 7 rotatably mounted on its top. The two rollers 7 are in movable contact with the bottom sides of the upper cover 6. Rotation of the lever 8 drives the rollers 7 to squeeze the upper cover 6. Support shafts 17 are fixedly connected to both sides of the garbage can shell 4. The top of the support shaft 17 is in active contact with the bottom of the corresponding lever 8. The support shaft 17 is used to restrict the bottom of the corresponding lever 8 to prevent the lever 8 from rotating forward. The two levers 8 are fixedly connected to the opposite sides of each other with a connector 16. The bottom of the connector 16 is fixedly connected to the top of the corresponding brake line 3. The connection between the lever 8 and the brake line 3 is achieved through the connector 16. This utility model can complete the two-point drive flip-top operation through a series of structural settings. At this time, the flip-top method makes the opening angle of the upper cover 6 larger than the opening angle transmitted by a single linkage. Moreover, the lightweight design of the brake line 3 can achieve efficient force transmission, which solves the problem of the bulky and complex structure of the traditional trash can foot pedal mechanism. The overall structure is simple and the manufacturing cost is significantly reduced compared with the existing technology. It has both technological innovation and market application value.

[0031] Working principle: When in use, the user applies force to the foot pedal 1 to open the lid. The foot pedal 1 causes the fixed sheet metal 10 to slide on the two slide rails 2. As the fixed sheet metal 10 moves downward, it stretches the two return springs 12, pulling the two brake cables 3 downward. This causes the bottom ends of the brake cables 3 to move downward, and the brake cables 3, through their corresponding connectors 16, pull the lever 8, causing the bottom end of the lever 8 to rotate downward. The lever 8 drives the corresponding rotating shaft 9 to rotate counterclockwise. Simultaneously, the top end of the lever 8 rotates upward, causing the corresponding roller 7 to rotate upward and press against the bottom of the upper cover 6. Under this pressure, the upper cover 6 rotates backward to open 80°, allowing garbage to be placed into the garbage can shell 4. The user then removes the foot pedal force. The return spring 12, which is in a stretched state, releases its stored elastic potential energy, pulling the fixed sheet metal 10 upwards. The fixed sheet metal 10 drives the foot pedal 1 back to its original position and relaxes the tension on the two brake lines 3, thereby relaxing the tension on the lever 8. Then, the top cover 6 begins to fall and reset under the action of gravity, sealing the top of the trash can shell 4. The top cover 6 is rotated and reset by the two rollers 7 pressing the two levers 8, ready for the next foot pedal opening operation. The way the top cover 6 is opened by the two brake lines 3 in conjunction with the two levers 8 and the two rollers 7 makes the opening angle of the top cover 6 larger than that of a single linkage. Moreover, the lightweight design of the brake lines 3 achieves efficient force transmission, solving the problem of the bulky and complex structure of traditional trash can foot pedal mechanisms.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
