Description

Technical Field

[0001] The utility model relates to the technical field of bathroom equipment, in particular to a flushing straight pipe limiting structure for a wall-mounted toilet. Background Art

[0002] With the continuous changes in home decoration styles, wall-mounted toilets are becoming more and more people's choice. Wall-mounted toilets need to be used with hidden water tanks. The water outlet of the hidden water tank is connected to one end of the curved pipe, and the other end of the curved pipe is connected to the straight pipe, and then connected to the water inlet of the toilet through the straight pipe to supply water to the toilet. The hidden water tank and the curved pipe are pre-buried in the wall. If there is a problem of cracking and damage to the curved pipe, the wall needs to be demolished for repair, which is costly.

[0003] Figure 1 and Figure 2 The straight pipe limiting structure of the existing wall-mounted toilet is as follows: Figure 1 As shown, a limiting rib is provided inside the bent pipe. Figure 2 The middle straight pipe is inserted into the curved pipe, and the rear end face is against the limiting rib. However, the prior art has the following technical problems: the size of the straight pipe usually needs to be cut according to the actual installation size on site. If the straight pipe is too long after cutting, the toilet will not fit the wall during the installation of the wall-mounted toilet. In order to make the toilet close to the wall, the toilet will be pushed back with force. Since the straight pipe is too long, when the toilet is pushed back with force, the straight pipe will also push back against the limiting rib. When the limiting rib is subjected to greater force, the connecting end of the curved pipe and the straight pipe will bend backward, and the curved pipe will be at risk of breaking. Utility Model Content

[0004] The utility model aims to provide a flushing straight pipe limiting structure for a wall-mounted toilet to avoid the straight pipe from bending backward.

[0005] To achieve the above-mentioned purpose, the solution of the utility model is: a flushing straight pipe limiting structure for a wall-mounted toilet, comprising a mounting frame, a water tank, a curved pipe and a straight pipe;

[0006] The mounting bracket is used to install and fix the rear end of the toilet;

[0007] The water tank is fixed on the mounting frame;

[0008] The upper end of the curved pipe is connected to the water outlet of the water tank, and the lower end thereof extends forward transversely to form a transverse section;

[0009] The front end of the straight pipe is connected to the water inlet of the toilet, and the rear end is movably connected with the transverse section and sealed by a sealing member;

[0010] A limiting piece is also fixed on the mounting frame, and the limiting piece is used to limit the travel of the straight pipe moving backward.

[0011] Furthermore, when the straight pipe moves backward to a maximum stroke, the rear end of the straight pipe maintains a spacing from the bent pipe.

[0012] Furthermore, the straight tube is sleeved on the outer periphery of the transverse section, and the limiting member protrudes on the path of the straight tube moving backwards, and is used to abut against the rear end surface of the straight tube.

[0013] Furthermore, there are two limit members, which are used to abut against two opposite sides of the rear end surface of the straight pipe respectively.

[0014] Furthermore, the limiting member is integrally formed on the mounting frame.

[0015] Furthermore, a plug-in portion is protruded outwardly on the transverse section of the bent pipe, and a plug-in hole for the plug-in portion to be inserted is formed on the mounting frame. The plug-in portion is inserted into the plug-in hole to limit the bent pipe from moving backward.

[0016] Furthermore, the limiting member is made of metal material.

[0017] Furthermore, an annular installation groove is formed on the outer periphery of the transverse section of the curved pipe, and the sealing member is an annular structure and is embedded in the annular installation groove.

[0018] After adopting the above scheme, the beneficial effects of the utility model are:

[0019] The utility model prevents the lateral section of the bent pipe from being directly driven to move backwards by the movably sleeved connection between the straight pipe and the lateral section of the bent pipe when the straight pipe moves backwards, and a limiter is arranged on the mounting frame, so that the limiter can limit the travel of the straight pipe moving backwards, thereby preventing the straight pipe from moving backwards too far and hitting the bent pipe, causing the lower end of the bent pipe to bend backwards and deform, thereby causing the risk of damage to the bent pipe.

[0029] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] In the claims, specification and the above-mentioned drawings of the utility model, unless otherwise explicitly defined, directional words, such as the use of terms such as "center", "lateral", "longitudinal", "horizontal", "vertical", "top", "bottom", "inside", "outside", "up", "down", "front", "back", "left", "right", "clockwise", "counterclockwise" and the like to indicate directions or positional relationships are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation or be constructed and operated in a specific orientation, so they cannot be understood as limiting the specific protection scope of the utility model.

[0031] Figure 1 and Figure 2 1 is a schematic diagram of the assembly structure of a straight pipe 10 and a curved pipe 20 of a wall-mounted toilet in the prior art. In the prior art, the upper end of the curved pipe 20 is connected to a hidden water tank, and the lower end is connected to the straight pipe 10. The end of the straight pipe 10 away from the curved pipe 20 is connected to the water inlet at the rear end of the toilet, so that the water tank can supply water to the toilet. The water tank and the curved pipe 20 are pre-buried in the wall; Figure 1 As shown, the inner wall of the curved pipe 20 is provided with a limiting rib 30 protruding therefrom. During installation, the straight pipe 10 is inserted into the curved pipe 20 and abuts against the limiting rib 30. An annular installation groove 40 is formed on the inner wall of the curved pipe 20. A sealing ring 50 surrounds the installation groove 40. The sealing ring 50 seals the inner wall of the curved pipe 20 and the outer wall of the straight pipe. Generally, when installing the straight pipe 10, it is necessary to measure the actual installation dimensions at the installation site and cut the straight pipe 10. During the cutting process, if the installer fails to accurately cut the length of the straight pipe 10, the length of the straight pipe 10 exceeds the predetermined installation dimensions. During installation, in order to ensure that the toilet fits the wall, the toilet will be pushed back with force, so that the straight pipe 10 impacts the limiting rib 30. When the limiting rib 30 is subjected to excessive force, the lower end of the curved pipe 20 may be bent backward and deformed and break and be damaged. Since the curved pipe 20 is pre-buried in the wall, its maintenance cost is high.

[0032] In order to solve this technical problem, the utility model provides a flushing straight pipe limiting structure for a wall-mounted toilet, such as Figures 3 to 6As shown, it includes a mounting frame 1, a water tank 2, a curved pipe 3 and a straight pipe 4; the mounting frame 1 is mounted and fixed on the rear end of the toilet; the water tank 2 is fixed on the mounting frame 1, and is used to supply water to the toilet for flushing; the curved pipe 3 includes a vertical section 31, the upper end of the vertical section 31 is connected to the water outlet 21 of the water tank, and the lower end of the vertical section 31 extends forward and laterally to form a transverse section 32; the front end of the straight pipe 4 is connected to the water inlet of the toilet, and the rear end is movably connected to the transverse section 32, and is sealed by a sealing member 8. A limiting member 5 is also fixed on the mounting frame 1, and the limiting member 5 is used to limit the backward movement of the straight pipe 4 to prevent the straight pipe 4 from moving too far backward, and then the lower end of the curved pipe 3 is bent and deformed backward. There is no limitation on the way the straight tube 4 and the transverse section 32 of the curved tube 3 are mutually sleeved. The straight tube 4 can be sleeved on the outer periphery of the transverse section 32, or on the inner side of the transverse section 32. The two can be movably sleeved without fixed connection. In addition, there are many ways for the limiter 5 to limit the backward movement of the straight tube 4. The part of the straight tube 4 exposed from the transverse section 32 can be connected to the limiter to form a snap connection or elastic connection, or there can be other limiting methods, as long as it can limit the backward movement of the straight tube 4 to avoid the rear-end impact of the curved tube 3 and the curved tube 3 being broken by the impact of the straight tube 4.

[0033] In this specific embodiment, preferably, when the straight tube 4 moves backward to the maximum stroke, the limiter 5 can keep the rear end of the straight tube 4 spaced apart from the curved tube 3 to prevent the straight tube 4 from pushing against the curved tube 3. Of course, in other embodiments, the rear end of the straight tube 4 may also contact the curved tube 3, as long as the limiter 5 can limit the straight tube 4 from continuing to move backward and will not push against the curved tube 3. Those skilled in the art may design it according to the specific situation and is not limited to this.

[0034] In this specific embodiment, preferably, the straight tube 4 is sleeved on the outer periphery of the transverse section 32 of the curved tube 3, and the stopper 5 protrudes on the path of the straight tube 4 moving backward, and is used to abut against the rear end face of the straight tube 4. When the straight tube 4 is too long, when the straight tube 4 is pushed backward during installation, the rear end face of the straight tube 4 pushes against the stopper 5 instead of the curved tube 3. It is prevented that the straight tube 4 directly pushes against the curved tube 3 when moving backward.

[0035] In this specific embodiment, preferably, there are two stoppers 5, which are used to respectively abut on opposite sides of the rear end surface of the straight tube 4 to prevent the straight tube 4 from tilting when it hits the stoppers 5. The two stoppers 5 can simultaneously limit the rearward movement of the straight tube 4, and the force acting on the straight tube 4 is more balanced. Of course, in other embodiments, the number of stoppers 5 can also be three, four, etc., and is not limited thereto, as long as they can evenly abut on the rear end surface of the straight tube 4.

[0036] In this specific embodiment, a plug-in portion 33 is protruded from the transverse section 32 of the bent pipe 3, and a socket 6 for inserting the plug-in portion 33 is formed on the mounting frame 1. The plug-in portion 33 is inserted into the socket 6 to limit the backward movement of the bent pipe 3, so that the bent pipe 3 remains stable and prevents the bent pipe 3 from bending and deforming backward.

[0037] In this specific embodiment, a mounting groove 7 is formed on the mounting frame 1, and the transverse section 32 of the bent pipe 3 is installed in the mounting groove 7. Specifically, the mounting frame 1 is provided with a cross bar 11, and the cross bar 11 forms the above-mentioned mounting groove 7 at the position corresponding to the transverse section 32. The insertion hole 6 passes through the bottom wall of the mounting groove 7, and the bottom side of the transverse section 32 protrudes downward to form the above-mentioned plug-in portion 32. The plug-in portion 33 of the bent pipe 3 is inserted into the insertion hole 6, so that the bent pipe 3 is restricted in the mounting groove 7; two limit members 5 are respectively arranged on the opposite sides of the mounting groove 7, extending inward from the opposite side walls of the mounting groove 7 to the path where the straight pipe 4 moves backward, and the limit member 5 is arranged on the side close to the vertical section 31 of the bent pipe 3, so that the front part of the mounting groove 7 can reserve enough space for the straight pipe 4 and the transverse section 32 to be movably connected.

[0038] In this specific embodiment, the limiter 5 is made of metal material, and the straight tube 4 is made of plastic material. The limiter 5 made of metal material has high strength. When the straight tube 4 impacts the limiter 5, the limiter 5 made of metal material is more impact-resistant and is not easily damaged by the straight tube 4, which can effectively prevent the straight tube 4 from hitting the curved tube 3. Specifically, the limiter 5 can be made of iron material, stainless steel material, or other materials, as long as it is harder than the straight tube 4, but is not limited to this.

[0039] In this specific embodiment, Figure 5 As shown, the limit member 5 is integrally formed on the mounting frame 1, and the mounting frame 1 is made of iron material. The limit member 5 can also be made of iron material and is fixed to the mounting frame 1 by welding or fixed to the mounting frame 1 by screwing. It is easy to process, easy to form, and firm and stable. Of course, in other embodiments, it can also be fixed to the mounting frame 1 by other means, not limited to this.

[0040] In this specific embodiment, Figure 7 As shown, an annular mounting groove 34 is formed on the outer periphery of the transverse section 32 of the curved pipe 3, and the sealing member 8 is an annular structure and is embedded in the annular mounting groove 34, so as to seal between the curved pipe 3 and the straight pipe 4 when the straight pipe 4 is sleeved on the transverse section 32 of the curved pipe 3.

[0041] In this specific embodiment, the cross-section of the sealing member 8 is a V-shaped structure, and its opening direction is toward the side away from the straight pipe. One side of the opening is against the annular mounting groove 34, and the other side is a free end. When the straight pipe 4 is sleeved backward on the transverse section 32 of the curved pipe 3, the straight pipe 4 pushes backward against the free end of the sealing member 8, so that the free end is close to the annular mounting groove 34, so as to adjust the sealing between the straight pipe 4 and the curved pipe 3, improve the sealing performance, and avoid water leakage.

[0042] The above description is only a preferred embodiment of the present utility model and is not a limitation on the design of the present case. Any equivalent changes made based on the key design of the present case shall fall within the protection scope of the present case.
