Sometimes, according to construction requirements, the pipes need to be bent. At this time, L-shaped joints are generally used to connect the front and rear pipes. In this way, the pipes can be bent 90 degrees. Obviously, the above method leads to limited bending angles of the pipes. For some special construction conditions, sometimes the pipes need to be bent at other angles. At this time, ordinary joints cannot meet this requirement. In view of this, in-depth research was conducted on the above problems, and this case was created. Utility Model Content

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] Example: See Figure 1-5 , a pipeline connection device for water conservancy and hydropower construction, including a hose 2, both ends of the hose 2 are equipped with connecting pipes 1, and one end of the outer wall of the connecting pipe 1 is fixed with a flange 3, the bottom ends of the two connecting pipes 1 are equipped with a fixing frame 4, the inner wall of the fixing frame 4 is provided with a mounting plate 7, and the insides of the fixing frame 4 and the mounting plate 7 are penetrated with through holes of the same size, a mounting cylinder 6 is arranged below the hose 2, and a mounting rod 5 is arranged on one side of the mounting cylinder 6, one end of the mounting cylinder 6 and the mounting rod 5 are fixedly connected to the outer wall of the mounting plate 7, the inner wall of the mounting cylinder 6 is provided with a rotating cylinder 16, and one end of the rotating cylinder 16 extends to the outside of the mounting cylinder 6 and is installed with a rotating ring 15, and one end of the mounting rod 5 penetrates to one end of the rotating cylinder 16;

[0021] Specifically, Figure 1 As shown, firstly, bolts are inserted into the fixing frame 4 and the mounting plate 7 so that the two can rotate coaxially, and then the actual use length of the mounting rod 5 is adjusted to change the spacing between the two mounting plates 7 to avoid affecting the bending of the hose 2. At this time, the device can be bent. After bending to a suitable angle, the bolts are tightened to connect and fix the fixing frame 4 and the mounting plate 7 to prevent the two from rotating easily. In this way, the device can be bent at any angle within a certain range, so that the front and rear installed pipes form a suitable angle.

[0022] The inner wall of the installation cylinder 6 is provided with a plurality of annular grooves, and the outer wall of the rotating cylinder 16 is provided with a corresponding number of annular blocks, and the rotating cylinder 16 is rotatably connected with the installation cylinder 6 through the cooperation between the annular blocks and the annular grooves;

[0023] The outer wall of the mounting rod 5 is provided with two grooves 13, and the inner wall of the mounting tube 6 is fixed with two fixing blocks 17, and one end of the fixing blocks 17 extends to the inside of the grooves 13;

[0024] The outer wall of the mounting rod 5 is provided with an external thread, and the inner wall of the rotating cylinder 16 is provided with an internal thread matching therewith;

[0025] Specific. Figure 1 , Figure 3 and Figure 4As shown, the rotating ring 15 drives the rotating cylinder 16 to rotate accordingly, and the mounting rod 5 is threadedly matched with the rotating cylinder 16. At the same time, the mounting rod 5 is restricted from rotating by the matching of the groove 13 and the fixing block 17. Therefore, the mounting rod 5 can move in a directional manner, thereby adjusting the protruding length of the mounting rod 5 from the inside of the mounting cylinder 6, thereby achieving the effect of adjusting the actual use length of the mounting rod 5.

[0026] A plurality of fixing plates 14 are installed at equal angles on the outer wall of the rotating ring 15, and the interior of each fixing plate 14 is horizontally penetrated by a limiting hole 18;

[0027] A fixing box 12 is fixed to the outer wall of the mounting tube 6, and two return spring rods 11 are installed at one end of the fixing box 12, and a moving block 10 is installed at one end of the two return spring rods 11, and a clamping block 8 is fixed to one end of the moving block 10, and one end of the clamping block 8 extends to the outside of the fixing box 12, and a lever 9 is arranged on the outside of the fixing box 12, and one end of the lever 9 is fixed to one end of the moving block 10 through a connecting piece;

[0028] The cross-sectional shapes of the clamping block 8 and the limiting hole 18 are both cylindrical, and the diameters of the clamping block 8 and the limiting hole 18 are the same;

[0029] Specifically, Figure 1 , Figure 2 , Figure 4 and Figure 5 As shown, before rotating the rotating ring 15, the lever 9 can be moved to drive the moving block 10 to overcome the return spring rod 11 and move, so as to prevent the block 8 from blocking the fixed plate 14. After rotating the rotating ring 15 to adjust the mounting rod 5 to a suitable position, the rotating ring 15 is slightly adjusted to align a certain fixed plate 14 with the block 8. With the help of the thrust of the return spring rod 11 on the moving block 10, the block 8 is stuck in the inside of the limiting hole 18, thereby limiting the position of the corresponding fixed plate 14 and preventing the rotating ring 15 from rotating.

Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
