Description

Technical Field

[0001] This utility model relates to the field of squat toilet technology for trains, and in particular to a water-saving squat toilet assembly for trains that can be quickly disassembled. Background Technology

[0002] Toilet systems come in various forms, but can be broadly categorized into four types: recirculating toilets, vacuum toilets, jet toilets, and flush toilets with a biological treatment tank.

[0003] The waste tank is made of stainless steel and is installed in the stainless steel base equipment compartment. It is fixed by mounting brackets and other supports and then connected to the vehicle body by bolts. The whole tank is suspended on the vehicle body base. The waste tank is equipped with level gauges for 80% and 100% water levels.

[0004] To fully utilize the space under the vehicle, the waste bin has a very complex design, so it uses a hand lay-up polyester fiberglass inner and outer shell with an internal steel frame. It is installed in the equipment compartment of an aluminum alloy underframe and suspended under the underframe crossbeam (with dovetail grooves) using a special bolt suspension structure. Special bolts are inserted through cuts on the underframe crossbeam and secured using positioning washers and countersunk screws. The nuts are double-locking nuts with strong anti-loosening capabilities, and the eccentric structure of the upper and lower nuts ensures tightness.

[0005] Furthermore, as a crucial component of the squat toilet assembly, the installation of the waste bin is of paramount importance. Quick disassembly and reassembly of the waste bin are necessary for rapid operation after the train arrives at the station. Existing waste bins are installed using positioning pads and countersunk screws, with double-locking nuts employing strong anti-loosening capabilities. The eccentric structure of the upper and lower nuts contributes to the difficulty of quick disassembly of the waste bin. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4The present invention relates to a quick-detachable water-saving squat toilet assembly for trains, comprising two side plates 1, an mounting plate 20 fixedly connected to the upper end of the two side plates 1, a fixing rod 2 fixedly provided between the ends of the two side plates 1, a double-threaded rod 3 movably installed between the ends of the two side plates 1, a movable plate 4 threadedly connected to the double-threaded rod 3, a support plate 5 fixedly provided at the lower part of the movable plate 4, and a first rotating wheel 7 and a second rotating wheel 8 respectively keyed to the ends of the two double-threaded rods 3, the first rotating wheel 7 and the second rotating wheel 8 being connected by a transmission belt 21.

[0026] The lower part of the two side plates 1 is fixedly connected to the C-shaped support frame 9, and the inner side of the C-shaped support frame 9 is equipped with a wedge block 11 by a spring 10.

[0027] In this embodiment, preferably, the first rotating wheel 7 and the second rotating wheel 8 are respectively disposed at the ends of the two double-threaded rods 3 that pass through one side plate 1, and the ends of the double-threaded rods 3 of the first rotating wheel 7 are provided with servo motors 6.

[0028] It should be noted that one end of the double-threaded rod 3 passes through the side plate 1, which facilitates the installation of the first rotating wheel 7 and the second rotating wheel 8, and provides power output through the servo motor 6, which facilitates the rotation of the first rotating wheel 7 and the second rotating wheel 8, thereby driving the double-threaded rod 3 to rotate.

[0029] In this embodiment, preferably, there are several C-shaped support frames 9, and several C-shaped support frames 9 are equally spaced at the lower part of the two side plates 1. Each C-shaped support frame 9 has a wedge block 11 installed on its inner side by a spring 10.

[0030] It should be noted that there are several U-shaped support frames 9, which are evenly spaced to facilitate the support of the squat toilet assembly 16 and maintain its balance and stability. This prevents the squat toilet assembly 16 from tilting due to uneven force. The spring 10 can push the wedge block 11, so that the wedge block 11 can be stably positioned at the lower part of the squat toilet assembly 16, thereby lifting the squat toilet assembly 16 upward.

[0031] In this embodiment, preferably, support rods 13 are fixedly provided at both ends of the inner side of the movable plate 4, and guide wheels 14 are movably installed in the tail and head of the support rods 13. A thin steel cable 15 is connected to the inner end of the movable plate 4, and a winding wheel 12 is connected to the middle key of the double-headed threaded rod 3. The thin steel cables 15 on both sides are wound around the winding wheel 12.

[0032] It should be noted that the support rod 13 is used to install the guide wheel 14, and the guide wheel 14 is used to guide the thin steel cable 15. When the double-headed threaded rod 3 rotates, it drives the winding wheel 12 to rotate, so that the winding wheel 12 can wind up the thin steel cable 15. This facilitates the pulling of the moving plates 4 on both sides through the winding wheel 12 and the thin steel cable 15, thus reducing the problem of the moving plates 4 becoming loose.

[0033] In this embodiment, preferably, it also includes a squat toilet assembly mechanism 16, with L-shaped buckle plates 17 fixedly provided on both sides of the upper end of the squat toilet assembly mechanism 16, and the support plate 5 is engaged with the L-shaped buckle plates 17.

[0034] It should be noted that the L-shaped buckle plate 17 on the squat toilet assembly mechanism 16 is designed to facilitate the engagement and connection of the movable plate 4 and the support plate 5, thereby enabling the squat toilet assembly mechanism 16 to be engaged and installed, and also facilitating disassembly and installation.

[0035] In this embodiment, preferably, a pipe 18 is fixedly connected to the upper middle part of the squat toilet assembly 16, and a sealing contact plate 19 is fixedly provided at the upper end of the pipe 18. The squat toilet assembly 16 is set in the U-shaped support frame 9.

[0036] It should be noted that the pipe 18 and sealing contact plate 19 on the squat toilet assembly 16 are designed to achieve a sealed connection with the toilet bowl, which facilitates the delivery of excrement into the interior of the squat toilet assembly 16.

[0037] The specific operational procedures for this application are as follows:

[0038] When in use, the squat toilet assembly 16 is inserted obliquely into the side plate 1 and the U-shaped support frame 9, so that the pipe 18 and the sealing contact plate 19 make corresponding contact with the toilet bowl on the train. Under the action of the spring 10, the wedge block 11 is pushed so that the wedge block 11 can be located at the lower part of the squat toilet assembly 16, thereby lifting the squat toilet assembly 16, so that the pipe 18 and the sealing contact plate 19 on the squat toilet assembly 16 make sealing contact with the toilet bowl to prevent the excrement from leaking.

[0039] When the squat toilet assembly 16 is lifted by the wedge block 11, the servo motor 6 on the outer side of the side plate 1 drives the double-headed threaded rod 3 at one end to rotate, and drives the double-headed threaded rod 3 at the other end to rotate synchronously through the first rotating wheel 7, the second rotating wheel 8 and the transmission belt 21. This allows the two double-headed threaded rods 3 to drive the moving plate 4 and the support plate 5 to move, and to snap the L-shaped buckle plate 17 on the squat toilet assembly 16, thus fixing the squat toilet assembly 16 in place. When the double-headed threaded rod 3 rotates, it drives the winding wheel 12 in the middle to rotate, causing the winding wheel 12 to pull the thin steel cable 15. The thin steel cable 15 is supported by the support rod 13 and the guide wheel 14 to maintain the balance and stability of the thin steel cable 15. This allows the winding wheel 12 to pull the moving plates 4 on both sides when winding the thin steel cable 15, preventing the moving plates 4 and the support plate 5 on both sides from becoming loose and causing the installation of the squat toilet assembly 16 to become loose.

[0040] The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principle of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
