As an important component of the drainage system in the residence, its performance directly affects the quality of indoor air and is very important for controlling the odor in the bathroom.

[0004] The inventor found the following problems in the prior art during the implementation of the present utility model: 1. The existing toilet flange is designed with a single-piece opening and closing plate, so the size of the whole opening and closing plate is too long, and there are L-shaped or S-shaped bends in the lower pipeline. Therefore, when discharging water, if the single-piece opening and closing plate is opened due to force, it is easy to hit the top of the L-shaped or S-shaped water seal at the bottom, resulting in the situation that it cannot be fully opened, thereby affecting the water flow. 2. The existing toilet flange is directly sleeved outside the connecting pipe at the bottom of the toilet and fixed by glue, but there is no connection between the top of the toilet flange and the toilet. Therefore, after a long time of flushing, the toilet flange may be detached from the connecting pipe, resulting in leakage. Summary of the Invention

Specific implementation manners

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] Please refer to Figures 1 to 6 , the present utility model provides a technical solution: a double - door toilet flange, including a pipe 6, and the pipe 6 includes a top 61 and a bottom 62. Among them, the top 61 is sleeved outside the connecting pipe at the bottom of the toilet, and the bottom 62 is located in the ground drainage pipe. Moreover, the upper opening of the top 61 is larger than the lower opening, and a fitting plate 1 is arranged outside the upper opening of the top 61, and the fitting plate 1 can be fitted with the bottom of the toilet.

[0030] At the same time, spring assemblies 7 are installed on both sides of the bottom opening of the pipe 6. A secondary opening - closing plate 8 is connected to the middle of one group of the spring assemblies 7, and a main opening - closing plate 9 is connected to the middle of the other group of the spring assemblies 7.

[0031] Therefore, in the actual use process, through the setting of the main opening and closing plate 9 and the secondary opening and closing plate 8, that is, the design of the split opening and closing plate, the length of the opening and closing plate is reduced, and thus it can be applied to the situation where the length space at the lower end of the pipeline is insufficient. Even if there are L-shaped or S-shaped bends in the lower pipeline, it will not affect the opening and closing degree of the water outlet baffle.

[0032] Meanwhile, through the setting of the fitting plate 1, the fitting plate 1 can be attached to the bottom of the toilet and fixed with glue, thereby stabilizing the installation of the toilet flange and avoiding the possibility of detachment. And since the pipeline 6 is made of deformable material, after the fitting plate 1 is fixed to the bottom of the toilet with glue, pressure can be exerted on the pipeline 6, making the connection more stable.

[0033] Moreover, the top of the fitting plate 1 is provided with ridges 11 for increasing friction, thus having an anti-slip effect. And the setting of the ridges 11 makes the connection between the glue and the fitting plate 1 closer, and further makes the connection between the toilet and the fitting plate 1 closer.

[0034] In this embodiment, as Figure 4 shown, the spring assembly 7 includes a first fixing block 703, and a third fixing block 705 is provided on one side of the first fixing block 703. And one ends of the first fixing block 703 and the third fixing block 705 are connected to the secondary opening and closing plate 8 or the main opening and closing plate 9.

[0035] Meanwhile, a second fixing block 704 is provided on the side of the first fixing block 703 close to the third fixing block 705, and a fourth fixing block 706 is provided on the side of the third fixing block 705 close to the first fixing block 703. And one end of a screw 701 penetrates through the inside of the third fixing block 705, and the other end of the screw 701 penetrates through the inside of the first fixing block 703. And a double torsion spring 702 is sleeved in the middle of the screw 701, and one end of the double torsion spring 702 is in contact with the bottom of the secondary opening and closing plate 8 or the main opening and closing plate 9.

[0036] Therefore, in the actual use process, the two spring assemblies 7 are respectively located on the center lines of the secondary opening and closing plate 8 and the main opening and closing plate 9. When the water flow flushes open the secondary opening and closing plate 8 and the main opening and closing plate 9, the two spring assemblies 7 will be impacted by the secondary opening and closing plate 8 and the main opening and closing plate 9, and the force will act on the two spring assemblies 7. After the water flow ends, the two spring assemblies 7 will make the secondary opening and closing plate 8 and the main opening and closing plate 9 rebound.

[0037] Secondly, a bottom plate 4 is provided on the outer side of the bottom 62 of the bottom part, and the spring assemblies 7 are installed on both sides of the opening at the bottom of the pipeline 6 on the bottom plate 4.

[0038] Therefore, in the actual use process, through the setting of the bottom plate 4, the spring assemblies 7 can be installed more stably. This is because the thickness of the pipeline 6 alone is relatively small, and thus the installation area is relatively small. However, due to the setting of the bottom plate 4, the installation area is increased, and thus the spring assemblies 7 can be installed more stably.

[0039] Moreover, one end of the double torsion spring 702 is attached to the bottom of the opening and closing plate, and the other end of the double torsion spring 702 is hooked to the outer wall of the bottom plate 4. When the water flow flushes open the secondary opening and closing plate 8 and the main opening and closing plate 9, both the end of the double torsion spring 702 attached to the bottom of the opening and closing plate and the end hooked to the outer wall of the bottom plate 4 bend simultaneously, and the opening and closing plate can bounce back after the water flow ends.

[0040] In this embodiment, as Figure 2 , Figure 3 , Figure 5 and Figure 6 shown, the area ratio of the secondary opening and closing plate 8 to the main opening and closing plate 9 is 4:6. Therefore, when the secondary opening and closing plate 8 and the main opening and closing plate 9 are affected by the water flow, due to the smaller area ratio of the secondary opening and closing plate 8, it will open later and bounce back first in the later stage.

[0041] At the same time, the contact surface between the secondary opening and closing plate 8 and the main opening and closing plate 9 is set to be inclined. Therefore, after the secondary opening and closing plate 8 and the main opening and closing plate 9 are closed, the inclined setting makes the contact between the opening and closing plates closer and more sealed.

[0042] Moreover, in order to make the tight and sealing effect better, a sealing member is provided on the contact surface between the secondary opening and closing plate 8 and the main opening and closing plate 9.

[0043] In this embodiment, as Figures 1 to 3 shown, a sealing rubber ring 3 is provided on the outside of the bottom 62, and there are three sealing rubber rings 3 and they are evenly distributed at equal intervals along the central axis direction of the pipeline 6.

[0044] Therefore, in the actual use process, through the three sealing rubber rings 3 on the pipeline 6, the pressure can be effectively relieved when the water flow rushes down from the top of the pipeline 6, so that the utility model will not fall off easily. At the same time, the three sealing rubber rings 3 can be three separate ones or integrally formed.

[0045] In this embodiment, as Figure 6 shown, two grooves 63 are symmetrically opened on the inner wall of the top 61.

[0046] Therefore, in the actual use process, the contact area between the rubber strip and the inner wall of the top 61 is increased, and further the connection between the top 61 and the connecting pipe at the bottom of the toilet is made more stable.

[0047] In this embodiment, as Figures 1 to 3 shown, a baffle 2 and a partition plate 5 are sequentially provided under the top 61 under the fitting plate 1, and the partition plate 5 is located at the connection between the top 61 and the bottom 62.

[0048] Among them, the fitting plate 1, the baffle 2, the isolation plate 5, the sealing rubber ring 3, and the bottom plate 4 are coaxial. Due to the coaxiality, the force on this assembly can be evenly distributed during operation. At the same time, the fitting plate 1, the baffle 2, the isolation plate 5, the sealing rubber ring 3, and the bottom plate 4 are all evenly distributed around the pipe 6. Therefore, when the top of the fitting plate 1 is adhered to the toilet, the part below the fitting plate 1 will be placed inside the water pipe. At this time, the baffle 2 can cover the top edge of the drainage pipe, thereby further limiting the position and making it not easy to fall off.

[0049] Therefore, it can be seen that the baffle 2 can be used for limiting, and the isolation plate 5 can be adapted to the bottom plate 4 to limit the installation position of the sealing rubber ring 3 and prevent the sealing rubber ring 3 from detaching.

[0050] The usage method and advantages of the present utility model: When using this double-door toilet flange, the working process is as follows:

[0051] As Figures 1 to 6 shown, first, before use, the top 61 is sleeved outside the connecting pipe at the bottom of the toilet, and the top of the fitting plate 1 is fitted to the top of the toilet. At this time, the top 61 and the connecting pipe, as well as the fitting plate 1 and the toilet, are fixed through glue. Then, the part below the fitting plate 1 is placed inside the water pipe. At this time, the baffle 2 can cover the top edge of the drainage pipe, thereby further limiting the position and making it not easy to fall off.

[0052] After the toilet flushes, the water flow will rush in from the top of the pipe 6. When the water flow reaches the bottom of the pipe 6, the water flow will impact the secondary opening and closing plate 8 and the main opening and closing plate 9, causing the secondary opening and closing plate 8 and the main opening and closing plate 9 to open, so that the spring assembly 7 is stressed. Moreover, after the water flow is finished, the secondary opening and closing plate 8 and the main opening and closing plate 9 will re-close due to the elastic force of the spring assembly 7. Because the area of the secondary opening and closing plate 8 is smaller, the secondary opening and closing plate 8 will open later and will bounce back first in the later stage. And because the contact edge between the secondary opening and closing plate 8 and the main opening and closing plate 9 is inclined or / and provided with a seal, it will be more sealed after closing, so that the water flow is not easy to flow out.

[0053] The above shows and describes the basic principles, main features, and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
