[0002] In particular, the present invention relates to an indoor assembled water pipe installation structure. Background Art

[0003] Indoor pipelines include electrical wires, water pipes, network cables, and fire protection pipes, etc. Water and electricity installation is an important step in home decoration. The installation of pipes and lines requires a reasonable layout, otherwise it will have a bad impact on people’s home life. Before construction, a reasonable construction design drawing needs to be designed to facilitate subsequent installation work and avoid errors.

[0004] When installing water and electricity pipelines, some auxiliary pipelines need to be welded, but during the welding process, the pipelines need to be kept horizontal and fixed to be better welded, and sometimes the elbows need to be fixed and welded. For example, the Chinese patent utility model patent CN213672654U discloses an assembled indoor drainage pipeline channel structure, including a main board, a sub-board and a fixing bolt, the upper surface of the fixing bar is provided with a slide groove, the interior of the slide groove is slidably connected with a first slider, the upper surface of the first slider is provided with a main telescopic rod, and the top of the main telescopic rod is provided with a first L-shaped plate. In the above-mentioned assembled indoor drainage pipeline channel structure, the first slider and the second slider can slide left and right through the slide groove and the inner slide groove, and are fixed by the extrusion rod. The auxiliary pipeline to be welded can be placed on the upper surface of the first L-shaped plate and the second L-shaped plate, the pressing plate slides to the right to clamp the auxiliary pipeline, and the pressing plate is fixed by the connecting ring, which is convenient for adjustment according to the thickness of the auxiliary pipeline. The height of the top first L-shaped plate and the second L-shaped plate can be adjusted by the main telescopic rod and the sub-telescopic rod, so that the clamped auxiliary pipeline is kept horizontal for easy welding.

[0036] Technologies, methods, and systems known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and systems should be considered part of the authorization specification.

[0037] Embodiment 1: Figures 1 to 10 The figure is only one of the embodiments of the present invention, an indoor assembled water pipe installation structure, including a first flat plate 1 and a second flat plate 2, an upper convex plate 11 is provided at one end of the first flat plate 1 close to the second flat plate 2, and a lower convex plate 21 is provided at one end of the second flat plate 2 close to the first flat plate 1, the upper convex plate 11 and the lower convex plate 21 are rotatably connected by an adjusting member 3, a first fixing portion 4 for fixing the pipeline is provided on the first flat plate 1, and a second fixing portion 5 for fixing the pipeline is provided on the second flat plate 2.

[0038] In the present invention, the auxiliary pipeline passes through the first fixing portion 4 on the first plate 1 and the second fixing portion 5 on the second plate 2 in sequence, so that the first fixing portion 4 and the second fixing portion 5 fix the two ends of the auxiliary pipeline respectively.

[0039] Here, the first fixing part 4 includes a first fixing plate 41 arranged on the first flat plate 1, a first movable plate 42 connected to the first fixing plate 41, and a first supporting ring 43 arranged at an end of the first movable plate 42 away from the first fixing plate 41; the second fixing part 5 includes a second fixing plate 51 arranged on the second flat plate 2, a second movable plate 52 connected to the second fixing plate 51, and a second supporting ring 53 arranged at an end of the second movable plate 52 away from the second fixing plate 51.

[0040] First, the first movable plate 42 can be adjusted in height relative to the first fixed plate 41. Similarly, the second movable plate 52 can be adjusted in height relative to the second fixed plate 51, so that the first support ring 43 and the second support ring 53 supporting the auxiliary pipeline can be adjusted horizontally, and even if the entire device is set on an inclined ground or even a vertically set wall, the height error of the entire device can be absorbed, thereby ensuring that the auxiliary pipeline is in a horizontal setting state when fixed.

[0041] Secondly, the first plate 1 and the second plate 2 are rotatably connected via the adjusting member 3, so that the first plate 1 and the second plate 2 can rotate relative to each other, thereby adjusting the angle between the first fixing portion 4 and the second fixing portion 5, and can adapt to the fixing of auxiliary pipes with different bending angles.

[0042] Finally, a first connecting foot 412 is arranged under the first fixed plate 41, and a first T-slot 12 is arranged on the first flat plate 1 for facilitating the sliding of the first connecting foot 412; a second connecting foot 512 is arranged under the second fixed plate 51, and a second T-slot 22 is arranged on the second flat plate 2 for facilitating the sliding of the second connecting foot 512; and the number of the second connecting foot 512 and the second T-slot 22 is two, and a flat plate 511 is passed between the two second connecting feet 512; a first clamping bolt 413 is arranged on the first connecting foot 412; and a second clamping bolt 513 is arranged on the second connecting foot 512.

[0043] In this way, the distance between the first fixing part 4 and the second fixing part 5 can be adjusted at will. After the adjustment is completed, the stability of the position between the first fixing part 4 and the second fixing part 5 can be ensured by tightening the first clamping bolt 413 and the second clamping bolt 513, thereby adapting to the fixing of auxiliary pipes of different lengths.

[0044] Of course, a first elastic pad 431 is provided in the first support ring 43, and a second elastic pad 531 is provided in the second support ring 53, which effectively prevents the auxiliary pipeline from being damaged.

[0045] The indoor assembled water pipe installation structure of the present invention is easy to use, can adjust the distance between the first fixing part and the second fixing part and the angle adjustment in various directions, and the angle adjustment has high accuracy, and can be suitable for the fixation of auxiliary pipes with various outer diameters, different lengths and different curvatures.

[0046] Embodiment 2, still as Figures 1 to 10 The figure is only one of the embodiments of the present invention. On the basis of the first embodiment, in an indoor assembled water pipe installation structure of the present invention, the adjusting member 3 includes a step rod 31 and a step bearing 32. The upper convex plate 11 is provided with a first inner tooth hole 111 and a first smooth hole 112 arranged below the first inner tooth hole 111; the lower convex plate 21 is provided with a second inner tooth hole 211 and a third inner tooth hole 212 arranged below the second inner tooth hole 211; the step bearing 32 includes at least a portion of An upper bearing ring 321 is located in the first smooth hole 112, and a lower bearing ring 322 at least partially located in the second inner tooth hole 211, wherein the upper bearing ring 321 is provided with a long diameter hole 323, and the lower bearing ring 322 is provided with a short diameter hole 324; the stepped rod 31 is provided with a first long diameter axis 311, a second long diameter axis 312 with the same outer diameter as the first long diameter axis 311, a first short diameter axis 313, and a second short diameter axis 314 with the same outer diameter as the first short diameter axis 313 from top to bottom.

[0047] Moreover, the outer wall of the upper bearing ring 321 is smoothly arranged, the outer wall of the lower bearing ring 322 is provided with latching teeth, the inner wall of the long diameter hole 323 is smoothly arranged, the inner wall of the short diameter hole 324 is provided with latching teeth, the outer sides of the first long diameter axis 311 and the second short diameter axis 314 are both provided with latching teeth, and the outer sides of the second long diameter axis 312 and the first short diameter axis 313 are both smoothly arranged.

[0048] A circular plate 315 is provided at one end of the first long-diameter axis 311 away from the second long-diameter axis 312, and a grip hole 316 is provided on the circular plate 315. A return spring 213 for connecting with the second short-diameter axis 314 is provided in the third inner tooth hole 212; a scale 113 is provided on the upper side of the upper convex plate 11, and a side plate 317 for cooperating with the scale 113 is provided on the outer side of the circular plate 315.

[0049] Initially, the second short-diameter shaft 314 is engaged with the third inner tooth hole 212, the first long-diameter shaft 311 is engaged with the first inner tooth hole 111, and the outer teeth of the lower bearing ring 322 are engaged with the second inner tooth hole 211. At this time, the first plate 1 and the second plate 2 will not rotate relative to each other; the circular plate 315 is manually lifted up, and the grip hole 316 is convenient for holding the circular plate 315, thereby driving the step rod 31 to rise, so that the second short-diameter shaft 314 is engaged with the short-diameter hole 324, and the first long-diameter shaft 311 is disengaged from the first inner tooth hole 111. At this time, the second plate 2 is rotated to rotate around the center line of the step rod 31. At this time, the step bearing 32 is driven to rotate by the engagement between the second inner tooth hole 211 and the outer teeth of the lower bearing ring 322. At the same time, the step rod 31 is driven to rotate through the clamping action of the short diameter hole 324 and the second short diameter axis 314. Since the first long diameter axis 311 and the first inner tooth hole 111 are no longer clamped, the step rod 31 can rotate relative to the first plate 1. When the side plate 317 points to other scale lines on the scale 113, the circular plate 315 is released. At this time, the step rod 31 is driven downward by the action of the reset spring 213. Since the tooth profiles of each axis and hole are the same as the scale line distribution, the second short diameter axis 314 and the third inner tooth hole 212 can be re-clamped, and the first long diameter axis 311 and the first inner tooth hole 111 can be re-clamped, thereby locking the first plate 1 and the second plate 2, and completing the angle adjustment between the first plate 1 and the second plate 2.

[0051] Here, the first telescopic hole 411 and the second telescopic hole are both vertically arranged, so that the first movable plate 42 and the second movable plate 52 can be adjusted up and down. After the adjustment is completed, the first positioning bolt 414 is inserted through the first outer hole into the first inner hole 421 to complete the locking of the height of the first movable plate 42; similarly, the second positioning bolt 514 can complete the locking of the height of the second movable plate 52.

[0052] In addition, a limiting short plate 13 for blocking the end of the first T-slot 12 and a first notch 131 for facilitating the installation of the limiting short plate 13 are provided on the side of the first flat plate 1, a first spring 132 for connecting with the limiting short plate 13 is provided in the first notch 131, and the end of the limiting short plate 13 away from the first spring 132 is inclined; a limiting long plate 23 for blocking the end of the second T-slot 22 and a second notch 231 for facilitating the installation of the limiting long plate 23 are provided on the side of the second flat plate 2, a first spring 132 for connecting with the limiting long plate 23 is provided in the second notch 231 The second spring 232 is connected, and the end of the limiting long plate 23 away from the second spring 232 is inclined; in this way, under the limitation of the limiting short plate 13, the first connecting leg 412 can pass through the inclined edge of the limiting short plate 13 (pressing the first spring 132) and be inserted into the first T-slot 12, and then the limiting short plate 13 rises under the elastic force of the first spring 132, and the side of the limiting short plate 13 close to the first T-slot 12 is vertically arranged, so that the first connecting leg 412 cannot be separated from the first T-slot 12; similarly, the second connecting leg 512 can also pass through the limiting long plate 23 and slide into the second T-slot 22 but cannot be separated.

[0053] Finally, a sun gear 515 and a planetary gear 516 gear-connected to the sun gear 515 are provided in the parallel connection plate 511. The parallel connection plate 511 is meshingly connected with a manual wheel 517 extending to the outside of the parallel connection plate 511. The sun gear 515 is coaxially connected to the second fixed plate 51, so that the manual wheel 517 can be manually rotated to adjust the angle of the second fixed plate 51; and due to the planetary deceleration effect of the sun gear 515 and the planetary gear 516, the angle of the second fixed plate 51 can be finely adjusted.

[0054] Planetary deceleration is an existing technology and will not be described in detail here.

[0055] Of course, support feet 6 are provided below the first flat plate 1 and the second flat plate 2 .
