Description

Technical Field

[0001] The utility model relates to the technical field of toilets, and in particular to a self-sealing structure for pipeline translational docking and a toilet. Background Art

[0002] Biodegradable toilets are a new type of toilet that has appeared in recent years. They can degrade human feces through microorganisms. They are particularly suitable for use in RVs, yachts, nursing homes, and other indoor environments where it is not convenient to discharge dirt, such as caring for the elderly with limited mobility.

[0003] At present, most existing biodegradable toilets require regular removal of biodegradable containers for cleaning, but the existing biodegradable toilets basically set the removal position of the biodegradable container at the back of the toilet, resulting in the biodegradable toilet having to leave dozens of centimeters of space between the wall or wall panel behind it, making it completely unsuitable for installation in small space application scenarios such as RVs.

[0004] Therefore, in order to solve the above problems, some portable RV toilets have appeared on the market. However, when the existing portable RV toilets are moved, the water supply pipes and exhaust pipes must be bent and stretched repeatedly, which leads to leakage problems caused by damage to the pipes after long-term use.

[0005] Solving the above problems has become a top priority. Utility Model Content

[0006] In order to solve the technical problem that the pipelines of existing movable RV toilets are prone to leakage due to damage after long-term repeated bending and stretching, the utility model provides a self-sealing structure and a toilet for pipeline translation docking.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a self-sealing structure for pipeline translation docking, comprising a first mounting seat and a second mounting seat capable of translation along the first mounting seat, wherein at least one first pipeline is arranged on the first mounting seat, and the second pipeline having the same number as the first pipeline is arranged on the second mounting seat, characterized in that magnets are installed on the adjacent end faces of each first pipeline and each second pipeline, each magnet has a magnet through hole coaxially arranged with the corresponding first pipeline or the second pipeline, the magnets on each first pipeline can attract each other with the magnets on the corresponding second pipeline, thereby forming a magnetic attraction group in pairs, and the outer surface of a magnet in each magnetic attraction group is covered with a sealing gasket, and the sealing gasket has a sealing gasket through hole coaxially arranged with the magnet through hole of the corresponding magnet;

[0009] When the second mounting seat is translated to the set position, the two magnets of each magnetic attraction group attract each other to clamp the gasket located therebetween, and at the same time, the adjacent ends of each first pipe and each second pipe are kept in communication with each other one by one.

[0010] With the above self-sealing structure for pipe translation and docking, the first pipe and the second pipe are respectively and reliably installed on the first mounting seat and the second mounting seat. Therefore, both the first pipe and the second pipe can be made of rigid pipes, and almost no damage or leakage problems will occur to the pipes themselves during long-term use. When the first pipe and the second pipe are butted up and down by moving the second mounting seat, the gasket corresponding to it can be reliably clamped by the suction force of the two magnets of each magnetic attraction group. Thus, when the first mounting seat and the second mounting seat are in communication, the small gaps between adjacent magnets can be reliably blocked by the gasket to avoid water leakage or air leakage problems. At the same time, when moving the second mounting seat to stagger the first pipe and the second pipe, only the suction force of each magnetic attraction group needs to be overcome, and the operation is easy and convenient. And because there is no flexible pipe connection between the first pipe and the second pipe at all, and the magnets will not demagnetize during long-term use, and the corrosion resistance of the magnets and the gaskets is extremely good, the self-sealing structure for pipe translation and docking can not only achieve a reliable sealing effect when the first pipe and the second pipe are docked to avoid water leakage or air leakage problems, but also be very durable and not easily damaged during long-term use, thus greatly reducing the leakage risk.

[0011] In some embodiments, the aperture diameters of the magnet through-holes are all less than or equal to the aperture diameters of the corresponding first pipes or second pipes, and the aperture diameters of the gasket through-holes are all less than or equal to the aperture diameters of the corresponding magnet through-holes.

[0012] In some embodiments, the outer peripheral edge of the gasket is fixedly connected to the corresponding first mounting seat or second mounting seat;

[0013] Or,

[0014] The gasket is fixedly connected to the adjacent surfaces of the corresponding magnets.

[0015] In some embodiments, the outer peripheral edge of the gasket has an annular rib extending towards the direction close to the corresponding magnet, and the annular rib surrounds the corresponding magnet, and:

[0016] The outer peripheral wall of the annular rib is fixedly connected to the corresponding first mounting seat or second mounting seat;

[0017] Or,

[0018] The outer peripheral wall of the annular rib is fixedly connected to the outer edge of the corresponding magnet.

[0019] In some embodiments, an installation sink is recessed on the first mounting seat or the second mounting seat provided with a gasket. The gasket and the corresponding magnet are installed in the corresponding installation sink, and the outer surface of the gasket is flush with or lower than the notch of the corresponding installation sink.

[0020] In some embodiments, one side surface of the gasket close to the corresponding magnet has a butt joint pipe, and the inner hole of the butt joint pipe constitutes the gasket through hole. The butt joint pipe passes through the corresponding magnet through hole and then is inserted into the corresponding first pipe or second pipe.

[0021] In some embodiments, each first pipe and each second pipe are respectively fixedly installed on the corresponding first mounting seat or second mounting seat;

[0022] All the magnets not covered with the gasket are: fixed on the corresponding first mounting seat or second mounting seat, or fixed at the end of the corresponding first pipe or second pipe;

[0023] All the magnets covered with the gasket are: fixedly installed between the gasket and the corresponding first pipe or second pipe, or axially movably installed between the gasket and the corresponding first pipe or second pipe.

[0024] In some embodiments, the second mounting seat translates along the first mounting seat through a sliding fit structure.

[0025] In some embodiments, the gasket is made of silica gel, rubber, polyurethane or polytetrafluoroethylene.

[0026] The second aspect of the present application relates to a toilet adopting the above self-sealing structure for pipeline translation docking, including a toilet main body. The second mounting seat is the bottom plate of the toilet main body, so that the toilet main body can both protrude forward from the first mounting seat and retreat and support on the first mounting seat;

[0027] When the toilet main body retreats and supports on the first mounting seat, the adjacent ends of each first pipe and each second pipe are correspondingly kept in communication.

[0028] Adopting the above toilet, the toilet main body can be moved back and forth very conveniently, so as to conveniently take and place the biodegradable container. Moreover, the toilet can be installed against the wall, and thus is suitable for installation and use in space-limited application scenarios such as motorhomes. At the same time, through the ingenious design of the above self-sealing structure for pipeline translation docking, it can not only achieve a reliable sealing effect when pipelines such as water supply pipes and exhaust pipes are docked, avoiding problems such as water leakage or air leakage, but also be extremely durable. When the toilet main body is moved back and forth a large number of times, the self-sealing structure for pipeline translation docking is also very unlikely to be damaged, thereby greatly reducing the leakage risk and improving the use experience of toilet users.

[0046] The present utility model will be further described below in conjunction with embodiments and drawings.

[0047] Embodiment 1:

[0048] As Figures 3 - 6 shown, a self-sealing structure for pipeline translation docking mainly includes a first mounting seat 1 and a second mounting seat 2, wherein the second mounting seat 2 can translate along the first mounting seat 1.

[0049] At least one first pipeline 3 is provided on the first mounting seat 1, one end of each first pipeline 3 is fixedly connected to the first mounting seat 1, and the other end of each first pipeline 3 extends away from the second mounting seat 2.

[0050] The second mounting seat 2 is provided with second pipelines 4 having the same number as the first pipelines 3. Similar to the mounting structure of the first pipelines 3, one end of each second pipeline 4 is fixedly connected to the second mounting seat 2, and the other end of each second pipeline 4 extends away from the first mounting seat 1.

[0051] Therefore, when the second mounting seat 2 is translated to a set position, each first pipeline 3 can be coaxially arranged with the corresponding second pipeline 4. In this embodiment, the second mounting seat 2 is located above the first mounting seat 1, and the lower end interfaces of each second pipeline 4 are respectively aligned with the upper end interfaces of the corresponding first pipelines 3. At the same time, by translating the second mounting seat 2, each first pipeline 3 can be misaligned with the corresponding second pipeline 4.

[0052] In this embodiment, magnets 5 are installed on the adjacent end faces of each first pipeline 3 and each second pipeline 4, and each magnet 5 has a magnet through hole 51 coaxially arranged with the corresponding first pipeline 3 or second pipeline 4, that is: the magnet through hole 51 of the magnet 5 installed on the first pipeline 3 is coaxially arranged with the inner hole of the first pipeline 3, and the magnet through hole 51 of the magnet 5 installed on the second pipeline 4 is coaxially arranged with the inner hole of the second pipeline 4. And the magnets 5 on each first pipeline 3 can attract the magnets 5 on the corresponding second pipeline 4, so as to form magnetic attraction groups in pairs.

[0053] In particular, sealing gaskets 6 corresponding one-to-one to the magnets 5 thereon are provided on the first mounting seat 1, and each sealing gasket 6 covers the upper part of each magnet 5 on the first mounting seat 1. At the same time, each sealing gasket 6 has a sealing gasket through hole 61 coaxially arranged with the magnet through hole 51 of the corresponding magnet 5.

[0054] Therefore, when the second mounting seat 2 is translated to the set position, the two magnets 5 of each magnetic attraction group attract each other, thereby clamping the gasket 6 located therebetween. At this time, each gasket 6 is in interference fit with the corresponding two magnets 5 respectively. Therefore, each gasket 6 seals the tiny gap between the corresponding two magnets 5 respectively, avoiding the problem of water leakage or air leakage. At this time, the adjacent ends of each first pipe 3 and each second pipe 4 are kept in communication one by one, that is: the inner hole of the first pipe 3 is coaxially communicated with the inner hole of the corresponding second pipe 4, the magnet through hole 51 of the corresponding two magnets 5, and the gasket through hole 61 of the corresponding gasket 6, so that each first pipe 3 and each second pipe 4 are kept conducting, and can smoothly conduct water or gas.

[0055] In addition, when moving the second mounting seat 2 to stagger the first pipe 3 and the second pipe 4, only the suction force of each magnetic attraction group needs to be overcome, and the operation is easy and convenient; and, since there is no hose connection between the first pipe 3 and the second pipe 4 at all, and the magnets 5 will not demagnetize during long-term use, and the corrosion resistance of the magnets 5 and the gaskets 6 is extremely good, therefore, the self-sealing structure for pipeline translation docking can not only achieve a reliable sealing effect when the first pipe 3 and the second pipe 4 are docked, avoiding the problem of water leakage or air leakage, but also is very durable and not easily damaged during long-term use, thus greatly reducing the leakage risk.

[0056] In this embodiment, the gasket 6 can be made of common elastic sealing materials such as silica gel, rubber, polyurethane, polytetrafluoroethylene, etc. The gasket 6 of this embodiment is preferably made of silica gel, which not only has good elasticity and sealing performance, but also has good corrosion resistance, is durable, and has relatively low cost at the same time.

[0057] In this embodiment, the aperture of each magnet through hole 51 is less than or equal to the aperture of the corresponding first pipe 3 or second pipe 4, and the aperture of each gasket through hole 61 is less than or equal to the aperture of the corresponding magnet through hole 51, which can effectively reduce the water leakage risk when the first pipe 3 and the second pipe 4 are in communication. In this embodiment, it is preferred that the aperture of each gasket through hole 61 is less than the aperture of the corresponding magnet through hole 51, and the aperture of each first pipe 3 is greater than the aperture of the corresponding magnet through hole 51. The structure that gradually increases in steps from top to bottom can further reduce the water leakage risk when the first pipe 3 and the second pipe 4 are in communication.

[0058] In this embodiment, an installation sink is recessed on the first mounting seat 1, and the gasket 6 and the corresponding magnet 5 are installed in the corresponding installation sink. The upper surface of the gasket 6 is flush with or lower than the notch of the corresponding installation sink. By providing the installation sink, not only the reliable installation of the magnet 5 and the gasket 6 is ensured, but also the smoothness of the sliding fit between the first mounting seat 1 and the second mounting seat 2 can be ensured because the upper surface of the gasket 6 is flush with or lower than the notch of the corresponding installation sink.

[0059] The magnet 5 is preferably in an annular structure. At the same time, the upper and lower end faces of the magnet 5 are both planar structures, which not only facilitates the assembly of the magnet 5 but also improves the reliability of the mutual attraction between the upper and lower magnets 5. At the same time, the gasket 6 is preferably in a thin sheet structure. While ensuring the sealing performance, it can minimize the distance between the upper and lower magnets 5 as much as possible, thereby improving the reliability of the mutual attraction between the two magnets 5.

[0060] In this embodiment, the magnet 5 located on the second mounting base 2 is either fixed on the corresponding second mounting base 2 or fixed on the lower end of the corresponding second pipe 4, which is simple and reliable. The magnet 5 located on the first mounting base 1 is either fixed in the corresponding mounting sink or fixed on the upper end of the corresponding first pipe 3, as long as it is ensured that the magnet 5 is fixedly installed in the space formed by the enclosure of the gasket 6 and the mounting sink.

[0061] There are the following two installation methods for the gasket 6 in this embodiment:

[0062] Installation method 1 of the gasket 6: The circumferential outer edge of the gasket 6 is fixedly connected to the circumferential groove wall of the corresponding mounting sink near the notch.

[0063] Installation method 2 of the gasket 6: The gasket 6 is fixedly connected to the adjacent surface of the magnet 5 located below it.

[0064] Both of the above two connection methods can ensure the reliable installation of the gasket 6.

[0065] In this embodiment, the second mounting base 2 translates along the first mounting base 1 through a sliding fit structure 7. Specifically, the sliding fit structure 7 is composed of two groups of chutes 71 and sliders 72. The two chutes 71 are arranged in parallel on the upper surface of the first mounting base 1, and both chutes 71 extend in the front-rear direction. The two sliders 72 are arranged in parallel on the lower surface of the second mounting base 2, and both sliders 72 extend in the front-rear direction. The two sliders 72 are respectively slidably installed in the corresponding chutes 71, so that the second mounting base 2 can slide reliably and smoothly along the first mounting base 1 in the front-rear direction.

[0066] Embodiment 2:

[0067] Please refer to Figure 7 , the main structure of this embodiment is exactly the same as that of Embodiment 1, and the difference lies in that: the magnet 5 located on the first mounting base 1 is movably installed in the corresponding mounting sink. Specifically, the magnet 5 located below the gasket 6 is axially movably installed between the gasket 6 and the corresponding first pipe 3 or second pipe 4.

[0068] With such a design, when each first pipe 3 and each second pipe 4 are not docked in a one-to-one alignment, the inner edges of the gaskets 6 located on the first mounting seat 1 are all in a downward drooping state, that is: the height of each gasket 6 gradually decreases from the outer edge to the inner edge. At this time, since the highest position of each gasket 6 (the outer edge of each gasket 6) is only flush with or lower than the upper surface of the first mounting seat 1, it is possible to avoid excessive resistance or influence on the forward and backward movement of the second mounting seat 2 by the gaskets 6 (usually the friction of the gasket 6 is relatively large).

[0069] When the second mounting seat 2 is translated to the set position where each first pipe 3 and each second pipe 4 are in one-to-one alignment, the two magnets 5 of each magnetic attraction group attract each other, and the lower magnets 5 move upward to the limit position, and at the same time clamp the gasket 6 located therebetween, which also achieves an excellent sealing effect.

[0070] Embodiment 3:

[0071] Please refer to Figure 8 , the main structure of this embodiment is exactly the same as that of Embodiment 1, and the difference lies in that: the outer circumference of the gasket 6 has an annular rib 62 extending in the direction close to the corresponding magnet 5, and the annular rib 62 surrounds the corresponding magnet 5, which can effectively improve the installation reliability of the gasket 6 and is more durable.

[0072] Specifically, there are the following two installation methods for the gasket 6 in this embodiment:

[0073] Installation method 1 of the gasket 6: The outer wall of the circumferential direction of the annular rib 62 is fixedly connected to the wall of the corresponding installation sink.

[0074] Installation method 2 of the gasket 6: The outer wall of the circumferential direction of the annular rib 62 is fixedly connected to the outer edge of the corresponding magnet 5.

[0075] The above two connection methods can both ensure the reliable installation of the gasket 6.

[0076] Embodiment 4:

[0077] Please refer to Figure 9 , the main structure of this embodiment is exactly the same as that of Embodiment 3, and the difference lies in that: similar to Embodiment 2, the magnet 5 located on the first mounting seat 1 is movably installed in the corresponding installation sink. Specifically, the magnet 5 located below the gasket 6 can be axially movably installed between the gasket 6 and the corresponding first pipe 3 or second pipe 4, and the technical effects obtained by this embodiment through the above different technical features are also the same as those of Embodiment 2.

[0078] Embodiment 5:

[0079] Please refer to Figure 10, the main structure of this embodiment is exactly the same as that of Embodiment 1, and the difference lies in that: on one side surface of the gasket 6 close to the corresponding magnet 5, there is a butt joint pipe 63, and the inner hole of the butt joint pipe 63 forms a gasket through hole 61. The butt joint pipe 63 passes through the corresponding magnet through hole 51 and then is inserted into the corresponding first pipe 3 or second pipe 4. Through such a design, it can avoid the accumulation of dirt due to water storage between the magnet 5 and the first pipe 3, so that the gasket 6 plays a better sealing effect.

[0080] Embodiment 6:

[0081] Please refer to Figure 11 , the main structure of this embodiment is exactly the same as that of Embodiment 5, and the difference lies in that: similar to Embodiment 2, the magnet 5 located on the first mounting seat 1 is movably installed in the corresponding mounting sink. Specifically, the magnet 5 located below the gasket 6 can be axially movably installed between the gasket 6 and the corresponding first pipe 3 or second pipe 4. The technical effect achieved by this embodiment through the above different technical features is also the same as that of Embodiment 2.

[0082] In this embodiment, since the magnet 5 located below the gasket 6 can move up and down, especially when the magnet 5 located on the first mounting seat 1 attracts the magnet 5 above it, there is a gap between the magnet 5 located on the first mounting seat 1 and the upper end surface of the first pipe 3. Therefore, the role of the butt joint pipe 63 is particularly obvious.

[0083] Embodiment 7:

[0084] Please refer to Figure 12 , the main structure of this embodiment is exactly the same as that of Embodiment 5, and the difference lies in that: the gasket 6 also has the annular rib 62 of Embodiment 3, that is, the circumferential outer edge of the gasket 6 has an annular rib 62 extending towards the direction close to the corresponding magnet 5, and the annular rib 62 surrounds the corresponding magnet 5.

[0085] Therefore, the gasket 6 of this embodiment not only has good installation reliability and is durable through the setting of the annular rib 62, but also can avoid the accumulation of dirt due to water storage between the magnet 5 and the first pipe 3 through the setting of the butt joint pipe 63, so that the gasket 6 plays a better sealing effect.

[0086] Embodiment 8:

[0087] Please refer to Figure 13 , the main structure of this embodiment is exactly the same as that of Embodiment 7, and the difference lies in that: similar to Embodiment 2, the magnet 5 located on the first mounting seat 1 is movably installed in the corresponding mounting sink. Specifically, the magnet 5 located below the gasket 6 can be axially movably installed between the gasket 6 and the corresponding first pipe 3 or second pipe 4. The technical effect achieved by this embodiment through the above different technical features is also the same as that of Embodiment 2.

[0088] Example 9:

[0089] Please refer to Figure 14 , the main structure of this embodiment is exactly the same as that of Example 1, and the difference lies in that: there is no gasket 6 provided on the first mounting seat 1, but only a magnet 5 is fixedly installed; and each gasket 6 is provided on the second mounting seat 2. Specifically, the second mounting seat 2 is provided with gaskets 6 corresponding to the magnets 5 thereon one by one, and each gasket 6 covers the bottom surface of each magnet 5 on the first mounting seat 1. At the same time, in order to avoid excessive resistance to the forward and backward sliding of the second mounting seat 2 caused by the gasket 6, the bottom surface of the second mounting seat 2 is also recessed into a mounting sink, the magnet 5 is fixedly installed in the mounting sink, and the lower surface of the gasket 6 is flush with or higher than the notch of the corresponding mounting sink.

[0090] Example 10:

[0091] Please refer to Figure 15 , the main structure of this embodiment is exactly the same as that of Example 3, and the difference lies in that: similar to Example 9, there is no gasket 6 provided on the first mounting seat 1, but only a magnet 5 is fixedly installed; and each gasket 6 is provided on the second mounting seat 2. Specifically, the second mounting seat 2 is provided with gaskets 6 corresponding to the magnets 5 thereon one by one, and each gasket 6 covers the bottom surface of each magnet 5 on the first mounting seat 1. At the same time, the bottom surface of the second mounting seat 2 is also recessed into a mounting sink, the magnet 5 is fixedly installed in the mounting sink, and the lower surface of the gasket 6 is flush with or higher than the notch of the corresponding mounting sink. The technical effects achieved by this embodiment through the above different technical features are also the same as those of Example 9.

[0092] Example 11:

[0093] Please refer to Figure 16 , the main structure of this embodiment is exactly the same as that of Example 5, and the difference lies in that: similar to Example 9, there is no gasket 6 provided on the first mounting seat 1, but only a magnet 5 is fixedly installed; and each gasket 6 is provided on the second mounting seat 2. Specifically, the second mounting seat 2 is provided with gaskets 6 corresponding to the magnets 5 thereon one by one, and each gasket 6 covers the bottom surface of each magnet 5 on the first mounting seat 1. At the same time, the bottom surface of the second mounting seat 2 is also recessed into a mounting sink, the magnet 5 is fixedly installed in the mounting sink, and the lower surface of the gasket 6 is flush with or higher than the notch of the corresponding mounting sink. The technical effects achieved by this embodiment through the above different technical features are also the same as those of Example 9.

[0094] Example 12:

[0095] Please refer to Figure 17, the main structure of this embodiment is exactly the same as that of Embodiment 7, and the difference lies in that: similar to Embodiment 9, no gasket 6 is provided on the first mounting seat 1, and only the magnet 5 is fixedly installed; and each gasket 6 is provided on the second mounting seat 2. Specifically, the second mounting seat 2 is provided with gaskets 6 corresponding one by one to the magnets 5 thereon, and each gasket 6 covers the bottom surface of each magnet 5 on the first mounting seat 1. At the same time, the bottom surface of the second mounting seat 2 is also recessed into a mounting sink, and the magnet 5 is fixedly installed in the mounting sink, and the lower surface of the gasket 6 is flush with or higher than the notch of the corresponding mounting sink. The technical effects achieved by this embodiment through the above different technical features are also the same as those of Embodiment 9.

[0096] Embodiment 13:

[0097] Please refer to Figures 1 - 17 , a toilet, which adopts one or more of the self-sealing structures for pipeline translation and docking in Embodiments 1-12.

[0098] Specifically, the second mounting seat 2 is the bottom plate of the toilet main body 8 of the toilet, and the first mounting seat 1 is installed on the ground or floor or a dedicated mounting table. By setting the lengths and installation positions of the chute 71 and the slider 72 of the sliding fit structure 7, the toilet main body 8 can both protrude forward from the first mounting seat 1 and retreat and support on the first mounting seat 1, that is: when it is necessary to take out the biodegradable container in the toilet main body 8 from the rear, slide the toilet main body 8 forward to make it protrude from the first mounting seat 1; when the cleaning is completed, the toilet main body 8 retreats and supports on the first mounting seat 1, ensuring the reliability during normal use of the toilet.

[0099] Each first pipeline 3 on the first mounting seat 1 is respectively a pipeline such as a water supply water pipe and an exhaust pipe in a motorhome or indoors, and each second pipeline 4 on the second mounting seat 2 is respectively a pipeline such as a water supply water pipe and an exhaust pipe in the toilet main body 8. The self-sealing structure for pipeline translation and docking adopted by each pipeline can be flexibly selected according to different requirements for sealing performance. For example, a more suitable self-sealing structure for pipeline translation and docking is selected for the water supply water pipe, and another more suitable self-sealing structure for pipeline translation and docking is selected for the exhaust pipe.

[0100] Therefore, through the above design, the toilet body 8 can be very conveniently moved back and forth, so that the biodegradable container can be easily taken and placed. Moreover, the toilet can be installed against the wall, thus being suitable for installation and use in narrow spaces such as motorhomes. At the same time, through the ingenious design of the self-sealing structure for pipeline translation docking, it can not only achieve a reliable sealing effect when pipelines such as the water supply pipe and the exhaust pipe are docked, avoiding problems such as water leakage or air leakage, but also be extremely durable. Even if the toilet body is repeatedly moved back and forth a large number of times, the self-sealing structure for pipeline translation docking is very unlikely to be damaged, thus greatly reducing the leakage risk and improving the user experience of the toilet.

[0101] It should be noted that this toilet can be either a biodegradable toilet, an incineration toilet, or an ordinary toilet. The purpose of moving back and forth is to facilitate the maintenance of the toilet from the rear.

[0102] Furthermore, in order to improve the stability and reliability of the forward and backward movement of the toilet body 8, a supporting roller is installed at the front end of the second mounting seat 2 at the bottom of the toilet body 8. Correspondingly, a built-in notch for the supporting roller, which is adapted to the supporting roller, is formed at the front end of the first mounting seat 1. The supporting roller of the toilet body 8 always rolls and supports on the mounting plane at the bottom of the first mounting seat 1, that is, the roller rolls and supports on the ground, the floor, or a dedicated mounting table. When the toilet body 8 is fully retracted onto the first mounting seat 1, the supporting roller is located in the built-in notch for the supporting roller, making it look more beautiful.

[0103] In order to further improve the stability and reliability of the forward and backward movement of the toilet body 8, a supporting roller is also installed at the middle or rear part of the second mounting seat 2 at the bottom of the toilet body 8. Correspondingly, a roller guiding groove, which is adapted to the supporting roller, is formed by the depression on the upper surface of the first mounting seat 1. The roller guiding groove is parallel to the two sliding grooves 71, and the roller guiding groove is located at the middle position between the two sliding grooves 71.
