Description

Technical Field

[0001] This utility model relates to the field of high-speed train equipment technology, specifically to a connection device for a toilet in a high-speed train. Background Technology

[0002] Toilets (also known as sanitary ware) are facilities used to handle human excrement. They typically include toilets, squat toilets, and seated toilets. Toilets are indispensable equipment in public and private restrooms, and they come in a variety of different designs and functions to meet the needs of different environments.

[0003] On high-speed trains, toilets and sewage pipes are typically installed separately for alignment. To facilitate this alignment, the toilet pipe and sewage pipe are usually connected by a sleeve, leaving a gap between them. This gap allows odors from the sewage pipe to escape into the train, affecting its hygiene. Although gaskets can be used to seal the gap during installation, the toilet and sewage pipe are installed independently. To achieve a good seal, installing the gaskets usually requires multiple disassemblies and adjustments of the toilet, which is time-consuming and significantly impacts the efficiency of toilet installation on high-speed trains.

[0004] In view of the above-mentioned defects, the creator of this utility model has finally obtained this utility model after a long period of research and practice. Utility Model Content

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0025] Figure 3 This is a structural view of the expansion assembly; Figure 4 A structural view showing the connection between the pressure application component and the expansion component.

[0026] The present invention relates to a connection device for a toilet in a high-speed train, comprising a toilet pipe 1, a support assembly 2, a pressure application assembly 3, and an expansion assembly 4. The support assembly 2, the pressure application assembly 3, and the expansion assembly 4 are sequentially sleeved on the outside of the toilet pipe 1 from top to bottom. The toilet pipe 1 is fixedly mounted on the toilet. The pressure application assembly 3 has an air storage chamber. The expansion assembly 4 includes an annularly arranged expansion chamber and an annularly arranged elastic sheet 402. The support assembly 2 compresses the gas in the air storage chamber into the expansion chamber and causes the elastic sheet 402 to expand annularly to seal against the inner wall of the sewage pipe, thereby achieving a sealed connection between the toilet pipe 1 and the sewage pipe.

[0027] Specifically, the pressure application component 3 includes a connecting shell 301, which includes an inner ring plate, an outer ring plate, and a first connecting plate. The inner ring plate, the outer ring plate, and the first connecting plate are all circular, and the inner ring plate and the outer ring plate are respectively vertically fixed on the inner and outer sides of the first connecting plate, thereby making the cross-section of the connecting shell 301 U-shaped. The inner ring plate and the outer ring plate are sealed to the expansion component 4, thereby forming an annular gas storage cavity in the connecting shell 301. A piston ring 304 with a circular structure is provided in the gas storage cavity. The inner ring wall of the piston ring 304 is sealed to the inner ring plate, and the outer ring wall of the piston ring 304 is sealed to the outer ring plate. The piston ring 304 is connected to the support component 2, and the piston ring 304 is driven to move axially in the gas storage cavity by the support component 2 to compress the gas in the gas storage cavity.

[0028] The support assembly 2 includes a support ring 201, a vertical rod 203, and a spring 204. The support ring 201 is sleeved on the outside of the toilet pipe 1. A sliding hole 302 is provided on the first connecting plate. The vertical rod 203 is disposed in the sliding hole 302. One end of the vertical rod 203 is vertically fixedly connected to the support ring 201, and the other end is fixedly connected to the piston ring 304 through a push ring 303. The spring 204 is sleeved on the outside of the vertical rod 203, and both ends of the spring 204 are respectively in contact with the support ring 201 and the first connecting plate. The vertical rod 203 can drive the piston ring 304 to move axially in the gas storage cavity by the relative movement of the support ring 201 and the connecting shell 301.

[0029] A stop block 6 is fixedly installed on the outer ring plate. The support assembly 2 also includes a fixing ring 202, which is fixedly installed on the outer wall of the toilet pipe 1 to limit the support ring 201. The support ring 201 is located between the fixing ring 202 and the upright 203. During installation, the stop block 6 engages with the opening of the sewage pipe to limit the movement, and the fixing ring 202 limits the support ring 201. As the toilet pipe 1 is inserted into the sewage pipe, the distance between the support ring 201 and the connecting shell 301 gradually decreases, so that the upright 203 overcomes the elastic force of the spring 204 and moves the piston ring 304 toward the expansion assembly 4.

[0030] The expansion assembly 4 includes a connecting concave ring 401, which includes an upper ring plate, a lower ring plate, and a second connecting plate. The upper ring plate, the lower ring plate, and the second connecting plate are all circular, and the upper ring plate and the lower ring plate are respectively vertically fixed on the upper and lower sides of the second connecting plate, thereby making the cross-section of the connecting concave ring 401 U-shaped. The two sides of the elastic sheet 402 are respectively sealed and connected to the outer ring edges of the upper ring plate and the lower ring plate, thereby forming the expansion cavity in the connecting concave ring 401. The upper ring plate is fixedly connected to the connecting shell 301. The upper ring plate is provided with a through hole 405, and the expansion cavity and the gas storage cavity are connected through the through hole 405. The gas in the gas storage cavity can be squeezed into the expansion cavity through the through hole 405 by the compression of the piston ring 304.

[0031] Preferably, the through hole 405 is configured as an elongated slotted hole extending along an arc to improve the speed of airflow.

[0032] This invention improves the efficiency of the connection between the toilet and the sewage pipe by providing the support component 2 with the gas in the pressure component 3 delivered to the expansion component 4 during the installation of the toilet pipe into the sewage pipe. This causes the elastic sheet 402 to expand and form an annular seal that comes into close contact with the sewage pipe.

[0033] Example 2

[0034] The expansion assembly 4 further includes a spacer ring 403, which is annularly arranged. The inner ring wall of the spacer ring 403 is sealed to the upper ring plate, and the outer ring wall of the spacer ring 403 is sealed to the lower ring plate, thereby dividing the expansion cavity into an inner ring cavity and an outer ring cavity that are not interconnected. The outer ring cavity is connected to the through hole 405. The inner ring cavity is provided with a support plate 404. The two ends of the support plate 404 are fixedly connected to the second connecting plate and the spacer ring 403, respectively, to improve the structural stability of the spacer ring 403. By providing the spacer ring 403, the space inside the connecting concave ring 401 can be reduced, so as to increase the air pressure inside the connecting concave ring 401 and make the elastic sheet 402 expand more rapidly.

[0035] The connecting device for a toilet in a high-speed train according to the present invention further includes a guide component 5. The guide component 5 includes a conical ring 501. The conical ring 501 is configured as a cylindrical frustum structure. The conical ring 501 is fixedly disposed on the lower ring plate of the connecting concave ring 401. The outer diameter of the cross-section of the conical ring 501 gradually decreases in the direction away from the connecting concave ring 401, thereby facilitating insertion of the conical ring 501 into the sewage pipe.

[0036] The guide component 5 also includes a positioning ring 502, which is fixedly disposed on the outer wall of the toilet pipe 1 to limit the connection concave ring 401. The positioning ring 502 is disposed inside the conical ring 501, thereby restricting the support component 2, the pressure application component 3 and the expansion component 4 to the outside of the toilet pipe 1 through the positioning ring 502 and the fixing ring 202.

[0037] Preferably, two blocks 6 are symmetrically fixedly provided on the outer wall of the connecting shell 301. One end of each block 6 is fixedly connected to the outer wall of the connecting shell 301 through a connecting seat 601, thereby ensuring uniform and stable force when engaging with the sewage pipe.

[0038] The implementation principle of the connection mechanism of a toilet in a high-speed train is as follows: First, the device is installed on the toilet. Then, during toilet installation, the device is inserted into the sewage pipe, and the stop block 6 contacts the sewage pipe to lock and limit the connection shell 301. As the toilet continues to move downwards, the connection shell 301 moves closer to the support ring 201, compressing the spring 204. With the movement of the connection shell 301, the piston ring 304 can compress the air inside the connection shell 301, allowing air to enter the connecting concave ring 401, increasing the air pressure inside the connecting concave ring 401. This causes the elastic sheet 402 to expand and seal with the sewage pipe, thereby improving the efficiency of the connection between the toilet and the sewage pipe.

[0039] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
