[0002] The sinking bend in the toilet bowl has an arc-shaped return bend pipe, which achieves the effect of deodorization by sinking. Usually, the sinking bend on the market is formed by combining several PVC pipes with glue at the edges. After long-term use, the glue is prone to aging and leakage in the gap. At the same time, the traditional sinking bend is prone to shaking due to large water flow during use, and the overall stability is insufficient, which is also prone to leakage at the connection. Summary of the invention

[0003] The purpose of the utility model is to solve the above problems and provide a sinking bend for a toilet, which provides good sealing and is more stable when used as a whole.

[0004] The purpose of the utility model is achieved in this way:

[0005] A sinking bend for use in a toilet comprises a left bend and a right bend which are buckled to form the sinking bend, the left bend and the right bend having the same mirror image structure, and both the left bend and the right bend are integrally formed, the left bend and the right bend respectively comprise an inlet half pipe, a return bend half pipe and an outlet half pipe from a water inlet end to a water outlet end, the outer edges of the left bend and the right bend are formed with mounting ridges, and corresponding mounting holes are provided on the mounting ridges of the left bend and the right bend, the mounting holes on the left bend and the right bend are buckled and connected by bolts, the end faces of the left bend and the right bend are provided with sealing mounting grooves, and sealing strips are provided in the sealing mounting grooves.

[0006] The utility model is further configured that the edges of the mounting convex edges located at the inner side of the return-bending half pipe are connected to form a convex edge portion, and the mounting hole is opened on the convex edge portion.

[0007] The utility model is further configured such that the inlet half-tubes on both sides are buckled together to form a water inlet hole opening to the left, and the outlet half-tubes on both sides are buckled together to form a water outlet hole opening vertically downward.

[0008] The utility model is further configured that sealing rings are arranged in the water inlet and the water outlet.

[0009] The utility model is further configured that the mounting flange and the side walls of the left bend and the right bend are provided with a plurality of triangular reinforcing ribs, and the reinforcing ribs, the mounting flange and the left bend are integrally formed.

[0010] Compared with the prior art, the utility model has the following outstanding and beneficial technical effects:

[0011] 1. The submerged bend provided by the utility model adopts a left bend and a right bend which are formed by buckling, and are reinforced by the mounting holes on the mounting convex edges on both sides. At the same time, a sealing strip is arranged in the mounting groove to ensure good sealing of the left bend and the right bend when buckled, and the overall structure is complete and stable, and the installation is more convenient.

[0012] 2. The utility model further forms a convex edge portion inside the return bend half pipe, so that the overall structure of the return bend pipe is more stable and will not shake during use.

[0013] 3. The utility model further arranges sealing rings in the water inlet and outlet holes to provide good sealing between the bottom of the toilet bowl and the drain seat.

[0014] 4. The reinforcing ribs provided in the present invention provide good structural strength for the mounting flanges on the left bend and the right bend. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The present invention will be further described below with reference to the accompanying drawings. Figure 1 and Figure 2 :

[0023] A sinking bend for use in a toilet comprises a left bend 1 and a right bend 2 which are fastened together to form a sinking bend, the left bend 1 and the right bend 2 having the same mirror image structure, and both the left bend 1 and the right bend 2 are integrally formed, the left bend 1 and the right bend 2 respectively comprise an inlet half pipe 10, a return half pipe 11 and an outlet half pipe 12 from a water inlet end to a water outlet end, the outer edges of the left bend 1 and the right bend 2 are both formed with mounting flanges 3, and corresponding mounting holes 30 are provided on the mounting flanges 3 of the left bend 1 and the right bend 2, the mounting holes 30 on the left bend 1 and the right bend 2 are fastened and connected by bolts, the end faces of the left bend 1 and the right bend 2 are both provided with sealing mounting grooves 20, and sealing strips are provided in the sealing mounting grooves 20.

[0024] During use, the left bend and the right bend are buckled together, and the mounting convex edges on both sides are also buckled together, so that the mounting holes on both sides are aligned, and are locked and fixed by bolts. During the buckling process, the sealing strip in the sealing mounting groove 20 plays a sealing role, ensuring that the formed sinking bend can have good sealing performance. The provided sinking bend has a simple structure and is easy to install.

[0025] Preferably, the edges of the mounting flanges 3 located on the inner side of the return-bend half-pipe 11 are connected to form a flange portion 31 , and the mounting hole 30 is opened on the flange portion 31 .

[0026] like Figure 1 As shown, the convex edge 31 makes the overall structure of the return bend half-tube 11 stronger, and the return bend half-tube is not prone to vibration during use, ensuring that there will be no leakage during use.

[0027] Preferably, the inlet half-tubes 10 on both sides are buckled together to form a water inlet hole 4 opening to the left, and the outlet half-tubes 12 on both sides are buckled together to form a water outlet hole 5 opening vertically downward.

[0028] Preferably, sealing rings 40 are provided in the water inlet hole 4 and the water outlet hole 5 .

[0029] In the above structure, the placed sealing ring can provide better sealing when connected with the sewage outlet of the toilet bowl and the sewage seat.
