Abstract
Description
Technical Field
[0001] This utility model relates to the field of squat toilets, and in particular to an adjustable squat toilet closing motion device. Background Technology
[0002] In portable toilets, the squat toilet's excrement channel is equipped with a hinged flap. This flap serves two purposes: first, it reduces the amount of gas produced after decomposition from entering the toilet chamber; second, it prevents users from stepping into the excrement channel. As the squat toilet is used more frequently, the timing belt responsible for opening and closing the flap wears down, causing the flap to close less effectively or even fail to close at all. This allows some gas to enter the toilet chamber, compromising user safety. Furthermore, the existing opening and closing mechanism is inconvenient to maintain and requires replacement, increasing maintenance costs. Utility Model Content

Detailed Implementation
[0022] The technical solution of this utility model will be clearly and completely described below with reference to the embodiments. 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] See Figures 1-3 This utility model provides a technical solution:
[0024] An adjustable squat toilet closing mechanism includes an opening / closing frame 1, an adjusting rod 2, an adjusting seat 3, a rotating shaft 4, synchronous pulleys 7, a synchronous belt 5, an opening / closing drive component 6, and an opening / closing assembly. The opening / closing frame 1 has sliding grooves at both ends, all of which are parallel to each other. One end of the adjusting rod 2 is positioned in a sliding groove, and the other end is fixedly mounted on the adjusting seat 3. The rotating shaft 4 is rotatably mounted on the adjusting seat 3, with two shafts 4 arranged parallel to each other. Synchronous pulleys 7 are fixedly mounted at both ends of the rotating shaft 4, and the two synchronous pulleys 7 are connected by the synchronous belt 5. The fixed part of the opening / closing drive component 6 is hinged to the opening / closing frame 1, and the output part of the opening / closing drive component 6 is connected to one side of the synchronous belt 5. The opening / closing assembly is slidably mounted on the opening / closing frame 1 and fixedly connected to the synchronous belt 5. An adjusting bolt is provided between the opening / closing frame 1 and the adjusting rod 2. The rotating shaft 4 is mounted on the adjusting seat 3 via a bearing 12. The opening / closing frame 1 has an adjusting hole 18, through which the adjusting bolt passes and engages with the adjusting rod 2 via a threaded connection. The opening and closing frame 1 is fixed to the lower surface of the squat toilet 13. The opening and closing frame 1 is used to install the adjusting rod 2, adjusting seat 3, rotating shaft 4, synchronous pulley 7, synchronous belt 5, opening and closing drive component 6, opening and closing assembly, and connecting ring 15. Two adjusting rods 2 are provided at each end of the opening and closing frame 1. Each adjusting rod 2 is mounted on two existing bearings 12, which are housed within the adjusting seat 3. The adjusting seat 3 is located at the end of the adjusting rod 2. The direction of adjustment and movement of the adjusting rod 2 is perpendicular to the rotating shaft 4. A synchronous pulley 7 is fixedly installed at each end of the two rotating shafts 4. A synchronous belt 5 is mounted on each synchronous pulley 7. The opening and closing drive component 6 drives the synchronous belt 5 to move, which in turn drives the opening and closing assembly.
[0025] In some embodiments, the opening and closing assembly is connected to two synchronous belts 5, which are connected between the two ends of the two rotating shafts 4. The use of two synchronous belts 5 ensures smoother transmission between the first opening and closing plate 10 and the second opening and closing plate 11, preventing tilting during operation when they slide.
[0026] In some embodiments, the opening / closing drive 6 is an electric push rod in the prior art. The output part of the electric push rod is fixedly connected to the synchronous belt 5, and the fixed part of the electric push rod is hinged to the opening / closing frame 1. The fixed part of the electric push rod is hinged to the tailstock 8, and the tailstock 8 is fixedly mounted on the opening / closing frame 1. The tailstock 8 is provided with a through hole 9 that passes through and mates with the synchronous belt 5. The tailstock 8 is used to mount the electric push rod, which extends and retracts to drive the synchronous belt 5. The through hole 9 facilitates the passage of the synchronous belt 5 and prevents interference during the operation of the synchronous belt 5.
[0027] In some embodiments, the opening and closing assembly includes a first opening and closing plate 10, a second opening and closing plate 11, a first connecting ear, and a second connecting ear. The first connecting ear is fixedly provided on both ends of the first opening and closing plate 10 and is connected to one side of the timing belt 5. The second connecting ear is fixedly provided on both ends of the second opening and closing plate 11 and is connected to the other side of the timing belt 5. The first connecting ear and the second connecting ear are respectively provided on both sides of the rotating shaft 4, and the first opening and closing plate 10 and the second opening and closing plate 11 cooperate with each other. Two rotating shafts 4 drive two synchronous belts 5 through four synchronous pulleys 7. The same side of the two synchronous belts 5 is connected to the first opening and closing plate 10 through the first connecting ear, and the other side of the two synchronous belts 5 is connected to the second opening and closing plate 11 through the second connecting ear. An electric push rod drives one of the synchronous belts 5 to work, thereby enabling the first opening and closing plate 10 and the second opening and closing plate 11 to open and close. When the first opening and closing plate 10 and the second opening and closing plate 11 are open, the excretion channel 14 on the squat toilet 13 can be completely opened. When the first opening and closing plate 10 and the second opening and closing plate 11 are closed, they can completely block the excretion channel 14 on the squat toilet 13. When the first opening and closing plate 10 and the second opening and closing plate 11 are closed together, they make full contact, reducing the leakage of gas from the sewage treatment equipment from the gap between the first opening and closing plate 10 and the second opening and closing plate 11.
[0028] In some embodiments, the opening and closing frame 1 is fixedly mounted on the squat toilet 13, and the opening and closing assembly cooperates with the excretion channel 14 on the squat toilet 13. A connecting ring 15 is fixedly mounted on the opening and closing frame 1, and the opening and closing frame 1 is positioned between the connecting ring 15 and the squat toilet 13. A connecting ring 16 is fixedly and sealed on the connecting ring 15, and a collection channel 17 is provided on the connecting ring 16, which passes through and cooperates with the excretion channel 14. The cross-sections of the excretion channel 14 and the collection channel 17 are both circular and coaxially arranged, and the diameter of the collection channel 17 is larger than the diameter of the excretion channel 14. The squat toilet 13 is a ceramic squat toilet in the prior art. The function of the connecting ring 15 is to fix the connecting ring 16 to the opening and closing frame 1. The connecting ring 16 is used to connect the sewage treatment equipment to prevent the feces produced by the user from entering the sewage treatment equipment and to prevent odor from spreading in the toilet. To prevent feces from falling onto the connecting ring 15 and the connecting ring 16, the diameter of the collection channel 17 on the connecting ring 16 is larger than the discharge channel 14 on the squat toilet 13. The outer wall of the connecting ring 16 is sealed and fixed to the inner wall of the connecting ring 15.
