[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. Because the urinal drain pipe of this utility model includes at least two drain pipes connected in sequence, and at least one drain pipe is telescopically fitted together with one end of an adjacent drain pipe and locked by a locking member that is detachably connected to the drain pipe, the length of the urinal drain pipe is adjustable through the telescopic design, thereby improving the versatility and engineering adaptability of the urinal drain pipe to a certain extent. In particular, the use of a locking member to lock the telescopic adjustment part greatly improves the firmness and stability of the connection of the telescopic adjustment part.

[0016] 2. At least two drainage pipes are included, namely a first drainage pipe and a second drainage pipe. The first drainage pipe extends vertically, and its lower end is retractably fitted with one end of the second drainage pipe. This allows the urinal drainage pipe of this invention to be adjusted in height, enabling it to adapt to the installation requirements of different urinal models. This significantly improves the product's versatility and applicability. It also allows the urinal drainage pipe to match the positional tolerance of the building's drainage outlet, effectively solving the problem of poor sealing caused by installation deviations. Furthermore, it simplifies the installation process, eliminating the need for on-site cutting or the addition of adapters, thus reducing material waste and shortening installation time.

[0017] 3. The clamping structure preferably includes multiple elastic arms spaced circumferentially at the end of the outer tube, so that the clamping structure is integrated with the outer tube, thereby reducing the number of parts and further simplifying the installation process.

[0018] 4. At least two sewage pipes also include a third sewage pipe, which extends horizontally and one end of the third sewage pipe is telescopically fitted together with the other end of the second sewage pipe, so that the urinal sewage pipe of this utility model can also be telescopically adjusted in the horizontal direction, which can adapt to various wall distances, further improve the compatibility of the urinal sewage pipe, and facilitate the replacement of the second sewage pipe.

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the adjustable urinal drain pipe and urinal of the present invention are not limited to the embodiments. Attached Figure Description

[0031] In this utility model, the terms "first," "second," and "third," etc., are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "left," "right," "front," "rear," "inner," and "outer" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is only for the convenience of describing this utility model, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation on the scope of protection of this utility model. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0032] In addition, in the description of this utility model, unless otherwise stated, "at least two" and "multiple" refer to two or more, and "at least one" refers to one or more.

[0033] Please see Figures 1-7 As shown, this utility model discloses an adjustable urinal drain pipe, comprising at least two drain pipes connected one after the other. One end of at least one drain pipe is retractably fitted onto the end of an adjacent drain pipe and locked by a locking member detachably connected to the drain pipes. Therefore, this utility model's urinal drain pipe, through its retractable design, allows for adjustable length, thereby improving its versatility and engineering adaptability to a certain extent.

[0034] The aforementioned at least two drainage pipes include a first drainage pipe 1 and a second drainage pipe 2. The first drainage pipe 1 extends vertically, and its upper end is connected to the drain outlet of the urinal, and is fitted with a first sealing gasket 4. The first sealing gasket 4 has double-layered walls, and the upper ends of the double-layered walls are integrally connected, forming an annular cavity between the double-layered walls to accommodate the upper end of the first sealing gasket 4. The lower end of the first drainage pipe 1 is telescopically fitted together with one end of the second drainage pipe 2 and locked by a locking member. Therefore, the urinal drainage pipe of this utility model can be telescopically adjusted in the height direction.

[0035] The lower end of the first sewage pipe 1 and one end of the second sewage pipe 2 are respectively an outer pipe and an inner pipe. The outer pipe is fitted over the inner pipe, and a first sealing ring 5 is fitted between them. The outer pipe has a first external thread 11 on its outer side, and a locking structure is fitted between the outer pipe and the inner pipe. In this embodiment, the lower end of the first sewage pipe 1 is the outer pipe, and one end of the second sewage pipe 2 is the inner pipe. Therefore, the lower end of the first sewage pipe 1 has a first external thread 11 on its outer side, and the lower end of the first sewage pipe 1 is fitted over one end of the second sewage pipe. A first sealing ring 5 is fitted at the end of one end of the second sewage pipe. In other embodiments, the lower end of the first sewage pipe 1 is the inner pipe, and one end of the second sewage pipe 2 is the outer pipe. The locking component for locking the first sewage pipe 1 and the second sewage pipe 2 includes a first nut 3, which is threadedly connected to the first external thread 11 and stops and limits the locking structure.

[0036] As a preferred embodiment, the clamping structure includes multiple elastic arms 12 spaced circumferentially at the end of the outer tube (i.e., the lower end of the first sewage pipe 1 in this embodiment). Each elastic arm 12 can elastically swing in the radial direction of the outer tube, and each elastic arm 12 has a locking protrusion 121 on its inner side at its tail end. The outer side of the inner tube (i.e., one end of the second sewage pipe 2 in this embodiment) has multiple locking structures spaced axially. The locking protrusions 121 at the tail ends of the multiple elastic arms 12 can be selectively locked into one of the locking structures. The first nut 3 stops the multiple elastic arms 12 on the outside to restrict the multiple elastic arms 12 from elastically swinging outward. In other embodiments, the clamping structure is a shrink sleeve that is separately provided from the outer tube and the inner tube and can be inserted between the outer tube and the inner tube. The first nut restricts the shrink sleeve from retracting.

[0037] The aforementioned multiple elastic arms 12 are integrally formed with the outer pipe (in this embodiment, the lower end of the first sewage pipe 1), and the outer surfaces of the multiple elastic arms 12 are inclined surfaces 122 (the inclination angle α of the inclined surface 122 is approximately 11°), so that the thickness of the multiple elastic arms 12 gradually increases from their root to their tail. The design of the inclined surface 122 can guide the movement of the first nut 3 to the outside of the elastic arm 12, and also make the first nut 3 move towards the tail of the elastic arm 12, and thus lock the elastic arm 12 more tightly. Each locking structure includes multiple locking grooves 21 distributed circumferentially along the inner pipe, but is not limited to this. In other embodiments, each locking structure includes a locking groove that is annular or arc-shaped. After the locking protrusion 121 of the elastic arm 12 is engaged in the locking groove 21, the overlap L between the two is slightly less than the depth of the locking groove 21.

[0038] In this embodiment, the second drain pipe 2 has a water trap 22, and its other end extends horizontally. The at least two drain pipes also include a third drain pipe 6, which extends horizontally and has one end retractably fitted onto the other end of the second drain pipe 2, and locked by another locking element. The other end of the third drain pipe 6 is for wall mounting and is fitted with a second sealing gasket 9, which is specifically a corrugated gasket, but not limited to this. The third drain pipe 6 is integrally formed or fixedly connected to a fixing seat 62 for abutting against the wall surface.

[0039] The locking components for locking the second sewage pipe 2 and the third sewage pipe 6 include a second nut 7. The other end of the second sewage pipe 2 has a second external thread 23, and one end of the third sewage pipe 6 has a third external thread 61. The second nut 7 is threadedly connected to the second external thread 23 and the third external thread 61. In this embodiment, one end of the third sewage pipe 6 is fitted inside the other end of the second sewage pipe 2, and the length of the second external thread 23 is greater than the length of the third external thread 61. A second sealing ring 8 is fitted between the other end of the second sewage pipe 2 and the one end of the third sewage pipe 6; specifically, the second sealing ring 8 is fitted outside the end of the other end of the second sewage pipe 2.

[0040] As a preferred embodiment, the second nut 7 is formed by splicing together multiple nut blocks 71 distributed circumferentially around the outside of the second sewage pipe 2 and the third sewage pipe 6, and adjacent nut blocks 71 can be connected by snap-fit ​​or screw fastening. This solves the problem of difficult installation of the one-piece second nut 7 in confined spaces. In this embodiment, the second nut 7 is specifically formed by splicing together two nut blocks 71.

[0041] This utility model discloses an adjustable urinal drain pipe. Through the above design, it can be adjusted not only in the height direction (with a height adjustment range of H1) but also in the horizontal direction (with a horizontal adjustment range of L1). Figure 4 As shown. Therefore, the urinal drain pipe of this utility model can not only adapt to the installation requirements of different models of urinals, significantly improving the versatility and applicability of the product, but also match the positional tolerance of building drainage outlets, effectively solving the problem of poor sealing caused by installation deviations, and simplifying the installation process. It eliminates the need for on-site cutting or the addition of adapter accessories, thereby reducing material waste and shortening installation time.

[0042] When adjusting in the height direction, first loosen the first nut 3, as follows: Figure 6 As shown, the first nut 3 releases each elastic arm 12, and then the lower end of the first drain pipe 1 slides relative to one end of the second drain pipe 2 until they reach the desired position. During this process, each elastic arm 12 swings outward elastically, causing its locking protrusion 121 to switch between different locking slots 21. When the lower end of the first drain pipe and one end of the second drain pipe slide relative to each other to the desired position, the locking protrusion 121 of each elastic arm 12 is engaged in the corresponding locking slot 21. Finally, the first nut 3 is tightened so that the inner side of the first nut 3 abuts against the outer side of the elastic arm 12, thereby stopping and limiting the elastic arm 12 and ensuring that the locking protrusion 121 of the elastic arm 12 is firmly engaged in the corresponding locking slot 21.

[0043] When adjusting in the horizontal direction, first loosen the second nut 7 so that it disengages from the third thread, as follows. Figure 6As shown, the other end of the second sewage pipe 2 and the other end of the third sewage pipe 6 are then slid relative to each other in the horizontal direction until they reach the desired position. Finally, the second nut 7 is tightened so that the second nut 7 is simultaneously screwed into the second external thread 23 and the third external thread 61.

[0044] This utility model discloses a urinal, including a urinal body 10. The bottom of the wash surface of the urinal body 10 is provided with a drain outlet 101, and the drain outlet 101 is connected to an adjustable urinal drain pipe as described above. Specifically, the upper end of the first drain pipe 1 is sealed and fitted over the drain outlet 101.

[0045] This utility model discloses a urinal. When installing the urinal's drain pipe, first confirm the horizontal distance L2 between the drain outlet 101 and the wall. Based on this distance, adjust the second drain pipe 2 and the third drain pipe 6 to a suitable position, and then tighten the second nut 7. Next, confirm the vertical distance H2 between the drain outlet 101 and the wall's drain inlet. Based on this distance, adjust the first drain pipe 1 and the second drain pipe 2 to a suitable position, and then tighten the first nut 3.

[0046] This utility model relates to an adjustable urinal drain pipe and urinal. The parts not described herein are the same as or can be implemented using existing technologies.

[0047] The above embodiments are only used to further illustrate an adjustable urinal drain pipe and urinal of the present invention. However, the present invention is not limited to the embodiments.
