Description

Technical Field

[0001] This application relates to the field of sanitation garbage bin technology, specifically a quick-release handle structure for sanitation garbage bins. Background Technology

[0002] Garbage bins are an indispensable basic sanitation facility in modern urban sanitation systems, mainly used for collecting and temporarily storing various types of household waste. To facilitate sanitation workers in handling, emptying, and transporting garbage, most garbage bins are equipped with one or more handles. These handles are usually fixed to the side wall or both ends of the garbage bin, and their basic function is to provide an effective point of leverage for the hand to overcome the weight of the garbage bin and its contents, completing a series of actions such as lifting, moving, and emptying. Structurally, traditional handles mostly adopt a fixed ring structure that is integrally injection molded with the bin body, or are hinged to the bin body by a simple axle pin, forming a basic, single-function load-bearing component.

[0003] However, the handles of existing sanitation garbage cans are mostly integrally injection molded, welded, or fastened with multiple sets of bolts. Although such structures can meet the initial strength requirements, the fixed connection between the handle and the body not only creates a difficult-to-clean hygiene dead corner, but also makes it easy for bacteria to remain and grow in a damp and dirty environment. Moreover, when the handle is damaged due to long-term fatigue, such as repeated pulling leading to cracks at the base, environmental aging, such as low-temperature brittleness, ultraviolet aging, or accidental impacts, such as vehicle scratches or tipping collisions, the entire garbage can often need to be replaced, resulting in high maintenance costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a quick-release handle structure for sanitation garbage bins, which solves the problem that fixed handles create hard-to-clean hygiene dead corners between the handle and the bin body, which are prone to bacteria growth and residue buildup in damp and dirty environments. Moreover, when the handle is damaged due to long-term fatigue, environmental aging, or accidental impact, the entire garbage bin often needs to be replaced, resulting in high maintenance costs.

[0005] To achieve the above objectives, this application provides the following technical solution: a quick-release handle structure for a sanitation garbage bin, comprising a bin body, a limiting shell fixedly connected to one side surface of the bin body, two fixed cylinders fixedly connected inside the limiting shell, a push rod slidably connected inside the fixed cylinder, a spring provided inside the fixed cylinder, the two ends of the spring being fixedly connected to the fixed cylinder and the push rod respectively, a movable block fixedly connected to the outer side of the push rod, an elongated hole adapted to the movable block being opened on the upper surface of the fixed cylinder, and a sliding rod slidably connected inside the limiting shell. A movable plate and a push plate are fixedly connected to both ends of the rod, respectively. A connecting rod is hinged to the upper surface of the movable block. The end of the connecting rod away from the movable block is hinged to the movable plate. A limit rod is fixedly connected to the end of the push rod away from the fixed cylinder. Two first fixed rods are slidably connected inside the upper surface of the limit shell. The first fixed rods have limit holes that are adapted to the limit rods. A first pull rod is fixedly connected between the two first fixed rods. A second fixed rod is slidably connected inside the first fixed rods. A second pull rod is fixedly connected between the two second fixed rods.

[0006] With the above solution, when using this device, the user only needs to push the push plate with their foot, which will then move the sliding plate via the slide rod. This causes the moving block to pull the push rod, thereby changing the position of the limiting rod and disengaging it from its locked state. The user can then easily pull the first lever to separate the first fixed rod from the bin body. When the user releases the push plate and the first fixed rod is inside the limiting shell, the spring can push the limiting rod to move, allowing it to enter the interior of the first fixed rod and fix it to the bin body. This design, which separates the first fixed rod from the bin body, solves the problem of fixed handles creating hard-to-clean hygiene dead corners between them and the bin body. These corners are prone to bacterial growth and residue buildup in damp and dirty environments. Furthermore, when the handle is damaged due to long-term fatigue, environmental aging, or accidental impact, the entire trash can often needs to be replaced, resulting in high maintenance costs.

[0007] Furthermore, a support block is hinged to the end of the second fixing rod away from the second tie rod, and the support block is located inside the first fixing rod and slidably connected to the first fixing rod.

[0008] With the above solution, the support block is hinged to the end of the second fixed rod and slidably connected to the first fixed rod. This not only guides the sliding of the second fixed rod to prevent it from shifting or getting stuck, but also restricts the second fixed rod from completely detaching from the first fixed rod, thus improving structural safety.

[0009] Furthermore, a positioning plate is fixedly connected to one side surface of the barrel, and the positioning plate has a first hole that matches the first fixing rod.

[0010] With the above solution, the first hole of the positioning plate is adapted to the first fixing rod, which can form double-sided support for the first fixing rod, reduce the shaking of the first fixing rod when it is under force, improve the stability of the connection between the handle and the bucket body, and prevent the handle from being crooked and affecting the use.

[0011] Furthermore, an elastic telescopic rod is fixedly connected to the side of the positioning plate, and a pressure plate is fixedly connected to the output shaft of the elastic telescopic rod.

[0012] With the above solution, the elastic telescopic rod drives the pressure plate to automatically reset, and the second fixed rod can be pressed and limited without manual adjustment, simplifying the handle length adjustment operation and improving ease of use.

[0013] Furthermore, two anti-slip plates are fixedly connected to one side surface of the clamping plate, and a second hole adapted to the clamping plate is provided on one side surface of the positioning plate and one side surface of the second fixing rod.

[0014] The above solution enhances the friction between the anti-slip plate and the pressure plate and the second fixed rod, preventing the second fixed rod from sliding on its own when the handle is under load. The second hole ensures that the pressure plate and the anti-slip plate can smoothly pass through the positioning plate and contact the second fixed rod, ensuring the reliability of the limiting function.

[0015] Furthermore, a mounting plate is fixedly connected to the side surface of the barrel away from the limiting shell, and two fixing blocks are fixedly connected to the side of the mounting plate. The top of the fixing block is provided with a groove that matches the second fixing rod.

[0016] The above solution provides a support point on the other side for the second fixing rod by fixing blocks and grooves on the mounting plate, enabling the handle to be switched between the two sides of the bucket, which can meet the needs of different operating scenarios and reduce the intensity of operation.

[0017] Furthermore, the fixing block has a first positioning hole inside and a positioning rod is movably connected thereto, and the first fixing rod has a second positioning hole inside that is adapted to the positioning rod.

[0018] With the above solution, the positioning rod, together with the first and second positioning holes, can quickly lock the connection between the second fixing rod and the fixing block, ensuring that the structure is stable when the handle is switched to the other side of the bucket, and preventing loosening and falling off during use.

[0019] Furthermore, both the interior of the limiting shell and the interior of the barrel are provided with first threaded holes and threaded with first bolts. The limiting shell is fixedly connected to the barrel through the first threaded holes and the first bolts. Both the interior of the positioning plate and the interior of the barrel are provided with second threaded holes and threaded with second bolts. The positioning plate is fixedly connected to the barrel through the second threaded holes and the second bolts. Both the interior of the mounting plate and the interior of the barrel are provided with third threaded holes and threaded with third bolts. The mounting plate is fixedly connected to the barrel through the third threaded holes and the third bolts.

[0020] The above solution achieves a stable assembly of the limiting shell, positioning plate, mounting plate and barrel body through the detachable connection of bolts and threaded holes. At the same time, it facilitates the individual repair and replacement of parts, reduces maintenance costs and extends the service life of the overall structure.

[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0022] 1. This quick-release handle structure for sanitation garbage bins, through the arrangement of a fixed cylinder, push rod, spring, moving block, sliding rod, moving plate, connecting rod, push plate, and first fixed rod, allows the user to easily separate the first fixed rod from the bin body by pushing the push plate with their foot. This, in turn, moves the moving block, pulling the push rod, causing the position of the limiting rod to change and disengage. The user can then easily pull the first fixed rod to separate it from the bin body. When the user releases the push plate and the first fixed rod is inside the limiting shell, the spring pushes the limiting rod to move into the interior of the first fixed rod, fixing it to the bin body. This design, where the first fixed rod is detachable from the bin body, solves the problem of fixed handles creating hard-to-clean cleaning corners that easily accumulate and breed bacteria in damp and dirty environments. Furthermore, when the handle is damaged due to long-term fatigue, environmental aging, or accidental impact, the entire garbage bin often needs to be replaced, resulting in high maintenance costs.

[0023] 2. This quick-release handle structure for sanitation garbage bins, through the setting of a second fixed rod, an elastic telescopic rod, a pressure plate, and an anti-slip plate, allows the user to pull the pressure plate to move it, separating the anti-slip plate from the second fixed rod. Then, the user can pull the second fixed rod, causing it to slide inside the first fixed rod, thereby adjusting the distance between the second handle and the bin body. This accommodates users of different heights or different handling scenarios, such as carrying by hand or using a hook. Through the setting of a support block, a fixed block, and a positioning rod, when the connection point between the support block and the second fixed rod is outside the first fixed rod, simply rotating the second fixed rod allows it to enter the fixed block. Then, the positioning rod connects the second fixed rod to the fixed block, fixing the position of the second handle. At this point, the first and second handles are located on opposite sides of the bin body, significantly improving the flexibility of dumping and transporting garbage during sanitation operations and reducing the operational intensity of sanitation workers.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 This embodiment of a quick-release handle structure for a sanitation garbage bin includes a bin body 1. A limiting shell 2 is fixedly connected to one side surface of the bin body 1. Two fixed cylinders 3 are fixedly connected inside the limiting shell 2. A push rod 4 is slidably connected inside the fixed cylinder 3. A spring 5 is provided inside the fixed cylinder 3. The two ends of the spring 5 are respectively fixedly connected to the fixed cylinder 3 and the push rod 4. A movable block 6 is fixedly connected to the outside of the push rod 4. An elongated hole adapted to the movable block 6 is opened on the upper surface of the fixed cylinder 3. A sliding rod 7 is connected to the movable block 6. A movable plate 8 and a push plate 11 are fixedly connected to both ends of the sliding rod 7, respectively. A connecting rod 9 is hinged to the upper surface of the movable block 6. The end of the connecting rod 9 away from the movable block 6 is hinged to the movable plate 8. A limit rod 10 is fixedly connected to the end of the push rod 4 away from the fixed cylinder 3. Two first fixed rods 12 are slidably connected inside the upper surface of the limit shell 2. The first fixed rod 12 has a limit hole that matches the limit rod 10. A first pull rod 13 is fixedly connected between the two first fixed rods 12. A second fixed rod 15 is slidably connected inside the first fixed rod 12. A second pull rod 16 is fixedly connected between the two second fixed rods 15. A support block 14 is hinged to the end of the second fixed rod 15 away from the second pull rod 16. The support block 14 is located inside the first fixed rod 12 and is slidably connected to the first fixed rod 12. A positioning plate 17 is fixedly connected to one side surface of the barrel 1. A first hole adapted to the first fixed rod 12 is opened inside the positioning plate 17. A first threaded hole is opened inside the limiting shell 2 and inside the barrel 1, and a first bolt is threadedly connected to it. The limiting shell 2 is fixedly connected to the barrel 1 through the first threaded hole and the first bolt. A second threaded hole is opened inside the positioning plate 17 and inside the barrel 1, and a second bolt is threadedly connected to it. The positioning plate 17 is fixedly connected to the barrel 1 through the second threaded hole and the second bolt. A third threaded hole is opened inside the mounting plate 21 and inside the barrel 1, and a third bolt is threadedly connected to it. The mounting plate 21 is fixedly connected to the barrel 1 through the third threaded hole and the third bolt.

[0033] It should be noted that the arrangement of the fixed cylinder 3, push rod 4, spring 5, moving block 6, slide rod 7, moving plate 8, connecting rod 9, push plate 11, and first fixed rod 12 allows the user to easily move the device by pushing the push plate 11 with their foot. This, in turn, moves the moving plate 8 via the slide rod 7, causing the moving block 6 to pull the push rod 4, thus changing the position of the limiting rod 10 and disengaging it from its locked state. The user can then easily pull the first pulling rod 13 to separate the first fixed rod 12 from the barrel 1. When the user releases the push plate 11 and the first fixed rod 12 is released from its locked state, the device is ready to be used. When the fixing rod 12 is inside the limiting shell 2, the spring 5 can push the limiting rod 10 to move, so that the limiting rod 10 enters the interior of the first fixing rod 12, fixing the first fixing rod 12 to the bin body 1. The design of the first fixing rod 12 being separate from the bin body 1 solves the problem of the dead corners that are difficult to clean thoroughly when the fixed handle is separated from the bin body. In a damp and dirty environment, bacteria can easily remain and grow. Moreover, when the handle is damaged due to long-term fatigue, environmental aging, or accidental impact, it is often necessary to replace the entire trash can, resulting in high maintenance costs.

[0034] Please see Figure 2 , Figure 4 and Figure 5 In this embodiment, a quick-release handle structure for a sanitation garbage bin is provided. An elastic telescopic rod 18 is fixedly connected to the side of the positioning plate 17. A pressure plate 19 is fixedly connected to the output shaft of the elastic telescopic rod 18. Two anti-slip plates 20 are fixedly connected to one side surface of the pressure plate 19. A second hole adapted to the pressure plate 19 is provided on one side surface of the positioning plate 17 and one side surface of the second fixing rod 15. An installation plate 21 is fixedly connected to the side surface of the bin body 1 away from the limiting shell 2. Two fixing blocks 22 are fixedly connected to the side of the installation plate 21. A groove adapted to the second fixing rod 15 is provided at the top of the fixing block 22. A first positioning hole is provided inside the fixing block 22 and a positioning rod 23 is movably connected thereto. A second positioning hole adapted to the positioning rod 23 is provided inside the first fixing rod 12.

[0035] It should be noted that the arrangement of the second fixed rod 15, the elastic telescopic rod 18, the pressure plate 19, and the anti-slip plate 20 allows the user to pull the pressure plate 19 to move it, separating the anti-slip plate 20 from the second fixed rod 15. Then, the user can pull the second fixed rod 15, causing it to slide inside the first fixed rod 12, thereby adjusting the distance between the second pull rod 16 and the bucket body 1. This accommodates users of different heights or different handling scenarios, such as carrying by hand or using hooks. The support block 14, the fixed block 22, and the fixed... The positioning rod 23 allows the device to be used such that, when the connection between the support block 14 and the second fixing rod 15 is outside the first fixing rod 12, the second fixing rod 15 can be rotated to enter the interior of the fixing block 22, and then the positioning rod 23 can be used to connect the second fixing rod 15 to the fixing block 22, thus fixing the position of the second pull rod 16. At this time, the first pull rod 13 and the second pull rod 16 are located on both sides of the barrel 1, which greatly improves the flexibility of dumping and transportation in sanitation operations and reduces the operational intensity of sanitation workers.

[0036] The working principle of the above embodiment is as follows: When in use, if it is necessary to separate the handle from the bucket body 1, the user pushes the push plate 11 with their foot. The push plate 11 drives the slide rod 7 to slide, and the moving plate 8 at the other end of the slide rod 7 moves synchronously. The moving plate 8 pulls the moving block 6 through the hinged connecting rod 9, causing the moving block 6 to slide, which in turn drives the push rod 4, which is fixed to the moving block 6, to slide inside the fixed cylinder 3 and compress the spring 5. When the push rod 4 moves, the limiting rod 10 moves with the push rod 4 and disengages from the limiting hole inside the first fixed rod 12. At this time, the first fixed rod 12 is released from the locking state, allowing... The user can pull the first lever 13 to separate the two first fixing rods 12 from the limiting shell 2, ultimately separating the first fixing rods 12 from the barrel body 1. When it is necessary to reinstall the handle, insert the first fixing rod 12 into the first hole inside the positioning plate 17, and then slide the first fixing rod 12 downwards into the hole of the limiting shell 2. At this time, release the push plate 11, the compressed spring 5 releases its elastic force, pushes the push rod 4 to reset, and the limiting rod 10 re-engages into the limiting hole of the first fixing rod 12, completing the fixation of the first fixing rod 12 to the barrel body 1. To adjust the handle length, the user pulls the pressure plate 19, causing it to stretch the elastic telescopic rod 18 and disengage the anti-slip plate 20 from the surface of the second fixed rod 15. This releases the anti-slip plate 20 from its restriction on the second fixed rod 15. At this point, the user can push or pull the second lever 16, causing the second fixed rod 15 to slide inside the first fixed rod 12. After adjusting to the desired length, the user releases the pressure plate 19. The elastic telescopic rod 18 retracts, causing the pressure plate 19 to reset. The anti-slip plate 20 then re-adheres to the surface of the second fixed rod 15, fixing its position through friction. When it is necessary to switch to the other side of the bucket 1 to use the handle, first pull out the second fixing rod 15 according to the above length adjustment steps until the support block 14 is completely separated from the inside of the first fixing rod 12. Rotate the second fixing rod 15 so that one end is inserted into the groove at the top of the fixing block 22 on the side of the mounting plate 21. Then insert the positioning rod 23 into the first positioning hole inside the fixing block 22 and the second positioning hole inside the first fixing rod 12 to fix the second fixing rod 15. At this time, the first pull rod 13 and the second pull rod 16 are located on both sides of the bucket 1 to meet the needs of different usage scenarios.
