[0022] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0023] A typical implementation mode of the present utility model is as Figure 1 shown, an adjustable support device for pipe elbow transformation includes a first support plate 1 and a second support plate 2. The first support plate 1 and the second support plate 2 are connected by a connecting member. The angle between the first support plate 1 and the second support plate 2 can be adjusted by using the connecting member. The ends of the first support plate 1 and the second support plate 2 away from the connecting member are connected by telescopic support rods.

[0024] The connecting member includes a first connecting rod 4 and a second connecting rod 5. The ends of the first connecting rod 4 and the second connecting rod 5 are hinged, so that the first connecting rod 4 and the second connecting rod 5 can rotate relative to each other. One end of the first connecting rod 4 away from the second connecting rod 5 is provided with a first fixing plate 6. The first fixing plate 6 forms a set angle with the first connecting rod 4. A bolt hole is opened on the first fixing plate 6. The first fixing plate 6 is fixedly connected to the end of the first support plate 1 by a bolt.

[0025] One end of the second connecting rod 5 away from the first connecting rod 4 is provided with a second fixing plate 7. The second fixing plate 7 forms a set angle with the second connecting rod 5. A bolt hole is opened on the second fixing plate 7. The second fixing plate 7 is fixedly connected to the end of the second support plate 2 by a bolt.

[0026] Since the first connecting rod 4 and the second connecting rod 5 can rotate relative to each other, the angle between the first support plate 1 and the second support plate 2 can be adjusted by using the connecting member to meet the construction requirements.

[0027] The telescopic support rod includes a first telescopic rod 8 and a second telescopic rod 9. The first telescopic rod 8 is slidably connected to the second telescopic rod 9. Specifically, the longitudinal section of the first telescopic rod 8 is U-shaped, and the upper edges of both side walls of the first telescopic rod 8 extend inwardly, so that a telescopic groove 10 is formed on the surface of the first telescopic rod 8. One end of the telescopic groove 10 is open. The second telescopic rod 9 can be inserted into the telescopic groove 10 from the open end of the telescopic groove 10 and can slide along the length direction of the telescopic groove 10. The width of the second telescopic rod 9 is the same as the width of the telescopic groove 10. Since the upper edges of both side walls of the first telescopic rod 8 extend inwardly, it plays a limiting role on the second telescopic rod 9 to prevent the second telescopic rod 9 from slipping out from the top of the telescopic groove 10.

[0028] A long hole 11 is provided on the second telescopic rod 9. The long hole 11 is opened along the length direction of the second telescopic rod 9. A first threaded hole is provided on the bottom surface of the open end of the telescopic groove 10. A locking bolt 12 is arranged in the first threaded hole. The locking bolt 12 passes through the long hole 11 on the second telescopic rod 9 and is threadedly connected to the first threaded hole. When the locking bolt 12 is loosened, the second telescopic rod 9 can slide in the telescopic groove 10, so as to adjust the length of the entire telescopic support rod. After the length of the telescopic support rod is adjusted, the locking bolt 12 is tightened, and the locking bolt 12 locks the second telescopic rod 9, thereby fixing the length of the telescopic support rod.

[0029] Both ends of the telescopic support rod are rotatably connected to one ends of the first support plate 1 and the second support plate 2 away from the connecting member. During use, the locking bolt 12 is loosened, and the angle between the first support plate 1 and the second support plate 2 is adjusted through the connecting member to meet the use requirements. At this time, the length of the telescopic support rod changes accordingly. After the adjustment is completed, the locking bolt 12 is tightened to fix the length of the telescopic support rod, and further fix the angle between the first support plate 1 and the second support plate 2.

[0030] A plurality of pipe fixing devices 3 are slidably connected to both the first support plate 1 and the second support plate 2. The pipes are fixed on the first support plate 1 and the second support plate 2 by using the pipe fixing devices 3. As Figure 2 shown, the pipe fixing device 3 includes a fixing block 31 and a pressing block 32. The pipe is placed between the fixing block 31 and the pressing block 32. Specifically, a fixing groove 33 is provided on one side surface of the fixing block 31. The longitudinal section of the fixing groove 33 is U-shaped, and both ends of the fixing groove 33 are open. The fixing groove 33 is adapted to the pipe, so that the pipe can be placed in the fixing groove 33. First through holes 34 are provided on the inner walls of the top and bottom of the fixing groove 33. The opening direction of the first through holes 34 is perpendicular to the pipe placement direction. The pressing block 32 is adapted to the fixing groove 33, so that the pressing block 32 can be placed in the fixing groove 33. Second through holes 35 are provided on the top and bottom of one end of the pressing block 32 away from the fixing block 31. The second through holes 35 are correspondingly arranged with the first through holes 34. A fastening bolt 36 is arranged in the first through holes 34 and the second through holes 35.

[0031] In use, first place the pipeline in the fixing groove 33, and then put the pressing block 32 into the fixing groove 33 so that the pipeline is located between the bottom surface of the fixing groove 33 and the pressing block 32. At this time, the first through hole 34 corresponds to the second through hole 35. Pass the fastening bolt 36 through the first through hole 34 and the second through hole 35 in sequence and lock it with a nut, thereby completing the fixation of the pipeline.

[0032] As Figure 3 shown, sliding grooves 13 are provided on the upper surfaces of the first support plate 1 and the second support plate 2. The sliding grooves 13 are arranged along the length directions of the first support plate 1 and the second support plate 2. Sliders are slidably connected in the sliding grooves 13. Second threaded holes are provided in the sliders. Circular holes are provided at the bottom of the fixing block 31. The circular holes are communicated with the fixing groove 33. Bolts are arranged in the circular holes. The bolts pass through the circular holes and are threadedly connected with the second threaded holes.

[0033] By providing the sliders and the sliding grooves 13 and providing threaded holes in the sliders and connecting them with the fixing block 31 by bolts, the pipeline fixing device 3 can be added according to the pipeline length, and the distance between multiple pipeline fixing devices 3 can also be adjusted to ensure the stability of pipeline fixation.
