[0015] 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.

[0016] Please refer to Figures 1-4 , a supply and return water pipe device convenient for installation and maintenance in this embodiment includes a connecting plate 2 and a main body 5 of the return water device. The connecting plate 2 is connected to the wall 1 through expansion bolts 3. Two support legs 4 perpendicular to it are provided at the bottom end of the connecting plate 2. A positioning mechanism is provided on the support legs 4. The main body 5 of the return water device is placed on the positioning mechanism. Two vertical plates 7 are arranged at intervals at both ends of the main body 5 of the return water device. An oval through hole is provided on the vertical plate 7. A locking block 11 adapted to the oval through hole is arranged between the two vertical plates 7. Two locking rods 8 are rotatably connected to the connecting plate 2, and the locking block 11 is sleeved and fixed on the locking rod 8 so that the locking block 11 rotates to abut against the two vertical plates 7.

[0017] In this embodiment, first, the connecting plate 2 and the wall 1 are installed through the expansion bolt 3 body, and then the return water device body 5 is placed on the positioning mechanism for positioning, so that the oval through hole of the vertical plate 7 is aligned with the locking block 11 and the locking rod 8. Then, the positioning mechanism and the return water device body 5 as a whole are moved towards the connecting plate 2. At this time, the locking rod 8 passes through the two vertical plates 7 through the oval through hole, and the locking block 11 passes through one of the vertical plates 7 through the oval through hole and just stays between the two vertical plates 7. At this time, the locking block 11 is rotated so that the locking block 11 cannot penetrate the oval through hole, thereby fixedly installing the return water device body 5. When maintenance is required, the locking block 11 is rotated again to cancel the limit of the oval connection hole, and the whole return water device can be moved for easy maintenance.

[0018] Preferably, as another embodiment of the present invention, the positioning mechanism includes a positioning plate 6, and a positioning groove 9 adapted to the return water device body 5 is provided on the positioning plate 6, and the return water device body 5 is placed on the positioning groove 9.

[0019] In this embodiment, by providing the positioning groove 9, it is convenient to determine the placement position of the return water device body 5, so as to facilitate the subsequent installation of the return water device body 5. A plurality of through holes are provided on the positioning plate 6, so that the pipes of the return water device body 5 can penetrate the positioning plate 6 and be connected to the return water device body 5.

[0020] Preferably, as another embodiment of the present invention, limiting sliding grooves are provided on both of the two support legs 4, and the bottom end of the positioning plate 6 is slidably connected to its corresponding limiting sliding groove through two sliders 10 respectively.

[0021] In this embodiment, by providing the limiting sliding grooves and the sliders 10, it is convenient to move and push the positioning plate 6 and the return water device body 5 on the positioning plate 6. When the positioning plate 6 moves towards the connecting plate 2 to the maximum distance, the locking block 11 is just located between the two vertical plates 7.

[0022] Preferably, as another embodiment of the present invention, the diameter of the locking rod 8 is adapted to the diameter of the oval through hole, and the end of the locking rod 8 away from the connecting plate 2 passes through the vertical plate 7 through the oval through hole.

[0023] In this embodiment, when the locking rod 8 passes through the vertical plate 7, the outer side of the locking rod 8 can be in contact with the oval through hole, so as to prevent the whole return water device body 5 from shifting in the four directions of up, down, left and right. After the locking block 11 is locked, it can prevent the return water device body 5 from shifting back and forth, thereby fixedly installing the whole return water device.

[0024] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
