DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0023] The present application provides a composite pipe that is easy to connect, which is mainly used to solve the problems that the traditional pipe connection method uses welding, which may cause complex operation and high cost in the application of composite pipes. The following technical solutions are provided and will be described in detail below:

[0024] Example 1:

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, in some embodiments, a first pipe 1 and a second pipe 2 are included, and multiple groups of first connecting strips 3 are fixedly installed at both ends of the first pipe 1, and multiple groups of second connecting strips 4 are fixedly installed at both ends of the second pipe 2. A connecting mechanism 5 for convenient connection is provided at the connection between the first pipe 1 and the second pipe 2. The connecting mechanism 5 includes a first connecting plate 501 and a second connecting plate 502 which are sleeved outside the first connecting strip 3 and the second connecting strip 4. One end of the first connecting plate 501 and the second connecting plate 502 are hinged and the other end is provided with a locking member 9. A connecting groove 503 is provided on the first connecting plate 501 and the second connecting plate 502, and the connecting groove 503 is adapted to the first connecting strip 3 and the second connecting strip 4. A first sealing gasket 504 is fixedly installed on the inner wall of the first connecting plate 501, and a second sealing gasket 505 is fixedly installed on the inner wall of the second connecting plate 502.

[0026] Specifically: by arranging multiple groups of first connecting strips 3 at both ends of the first pipe 1, and multiple groups of second connecting strips 4 at both ends of the second pipe 2, and equipping a connecting mechanism 5, the connection of the composite pipe is more convenient. Compared with the traditional welding method, this connection method is simpler to operate and can save installation time and labor costs.

[0027] The working principle here is: when the first pipe 1 and the second pipe 2 need to be connected, align one end of the first pipe 1 with one end of the second pipe 2, then open the first connecting plate 501 and the second connecting plate 502, so that the first connecting strip 3 and the second connecting strip 4 are aligned with the connecting grooves 503 on the first connecting plate 501 and the second connecting plate 502 respectively, then, put the first connecting plate 501 and the second connecting plate 502 outside the first connecting strip 3 and the second connecting strip 4, and bring them close to each other. Since one end of the first connecting plate 501 and the second connecting plate 502 are hinged, they can rotate relative to each other, which is convenient for the sleeve operation. When the other ends of the first connecting plate 501 and the second connecting plate 502 are close to each other, they are locked. Part 9 fixes them together. At this time, the first connecting strip 3 and the second connecting strip 4 are tightly clamped in the connecting groove 503 of the first connecting plate 501 and the second connecting plate 502, realizing the preliminary connection of the first pipe 1 and the second pipe 2. During the connection process, the first sealing gasket 504 on the inner side wall of the first connecting plate 501 and the second sealing gasket 505 on the inner side wall of the second connecting plate 502 will be squeezed, thereby filling the gap in the connection part, providing good sealing performance, and preventing liquid or gas leakage. Through this connecting mechanism 5, not only the first pipe 1 and the second pipe 2 are quickly and conveniently connected, but also the sealing of the connection is guaranteed by the setting of the sealing gasket, thereby improving the overall performance and reliability of the composite pipe.

[0028] like Figure 1 、 Figure 2 、 Figure 3As shown, in some embodiments, the locking member 9 includes a locking rod 901 rotatably connected to the other end of the first connecting plate 501, and the other end of the second connecting plate 502 is provided with a locking hole 902, and the locking rod 901 is threadedly connected to a locking bolt 903 through the locking hole 902, and the end of the locking bolt 903 is in contact with the upper surface of the second connecting plate 502. The working principle here is: when the first connecting plate 501 and the second connecting plate 502 need to be locked, the first connecting plate 501 and the second connecting plate 502 are placed outside the first connecting bar 3 and the second connecting bar 4, and they are brought close to each other. At this time, the locking rod 901 connected to the other end of the first connecting plate 501 is rotated to pass through the locking hole 902 on the second connecting plate 502, and then the locking bolt 903 is screwed into the thread of the locking rod 901. When the second connecting plate 502 is disconnected, the locking bolt 903 is tightened to the left and right, and the second connecting plate 502 is tightened. When the second connecting plate 502 is disconnected, the locking bolt 903 is tightened to the left and right, and the second connecting plate 502 is tightened to the left and right, and the second connecting plate 502 is tightened to the left and right, and the second connecting plate 502 is tightened to the left and right, and the first connecting plate 501 and the second connecting plate 502 are tightly fixed together, thereby achieving the clamping of the first connecting bar 3 and the second connecting bar 4, ensuring the connection firmness and sealing of the first pipe 1 and the second pipe 2. When disassembly is required, just rotate the locking bolt 903 in the opposite direction so that its end no longer contacts the second connecting plate 502, and then pull the locking rod 901 out of the locking hole 902 to open the first connecting plate 501 and the second connecting plate 502, and complete the disassembly of the pipeline.

[0029] Example 2:

[0030] The solution in Example 1 is further introduced below in conjunction with a specific working method, as described below:

[0031] like Figure 1 、 Figure 4 、 Figure 5As shown, in some embodiments, a support plate 6 is provided at the bottom of the first pipe 1 and the second pipe 2. The support plate 6 is constructed in a U shape and a plurality of universal wheels 7 are fixed to the bottom of the support plate 6. A fixing mechanism 8 for fixing the first pipe 1 and the second pipe 2 is provided inside the support plate 6. The fixing mechanism 8 includes a screw 801 threadedly connected to the inside of the support plate 6. The two ends of the screw 801 are provided with threads in opposite directions and the middle part of the screw 801 is symmetrically threaded with a slider 802. A slide groove 803 is constructed at the inner bottom of the support plate 6. The slider 802 slides in the slide groove 803 and a fixing plate 804 is fixedly installed on the top of the slider 802. The fixing plate 804 is constructed in an arc shape and the inner wall of the fixing plate 804 fits the outer wall of the first pipe 1 and the second pipe 2. The working principle here is: when the first pipe 1 or the second pipe 2 needs to be fixed, the pipe is placed in the U-shaped support plate 6, and then, by rotating the screw 801, due to the screw The two ends of the rod 801 are provided with threads in opposite directions, and the middle part of the screw 801 is symmetrically threadedly connected to the slider 802. Therefore, when the screw 801 is rotated, the two sliders 802 will move relative to or away from each other along the screw 801 under the restriction of the slide groove 803. When the slider 802 moves toward the middle, the arc-shaped fixing plate 804 fixed on the top of the slider 802 will also move toward the middle. Since the inner wall of the fixing plate 804 fits the outer wall of the first pipe 1 or the second pipe 2, as the fixing plate 804 moves, they will gradually clamp the pipe, thereby fixing the pipe. Conversely, when the pipe needs to be loosened, it is only necessary to rotate the screw 801 in the opposite direction so that the slider 802 drives the fixing plate 804 to move to both sides, releasing the clamping force on the pipe, and the pipe can be taken out from the support plate 6. The provision of multiple sets of universal wheels 7 facilitates the movement of the entire device, so that the position of the pipe can be adjusted more flexibly in actual application.

[0032] Working step 1: First, align one end of the first pipe 1 with one end of the second pipe 2, open the first connecting plate 501 and the second connecting plate 502 of the connecting mechanism 5, and align the first connecting strips 3 at both ends of the first pipe 1 and the second connecting strips 4 at both ends of the second pipe 2 with the connecting grooves 503 on the first connecting plate 501 and the second connecting plate 502 respectively, put the first connecting plate 501 and the second connecting plate 502 outside the first connecting strip 3 and the second connecting strip 4, and move them close to each other, rotate the locking rod 901 on the first connecting plate 501 so that it passes through the locking hole 902 on the second connecting plate 502, and then screw the locking bolt 903 into the locking rod 901 so that its end contacts the upper surface of the second connecting plate 502, thereby locking the first connecting plate 501 and the second connecting plate 502 to achieve the connection between the first pipe 1 and the second pipe 2. During the connection process, the first sealing gasket 504 on the inner wall of the first connecting plate 501 and the second sealing gasket 505 on the inner wall of the second connecting plate 502 are squeezed to fill the gap in the connection part, provide sealing performance, and prevent liquid or gas leakage.

[0033] Working step 2: Next, place the connected first pipe 1 and second pipe 2 in the U-shaped support plate 6, and rotate the screw 801 inside the support plate 6. Since the threads at both ends of the screw 801 are in opposite directions and cooperate with the slider 802 symmetrically threaded in the middle, the slider 802 moves relative to or in reverse under the restriction of the slide 803. When the slider 802 moves toward the middle, the arc-shaped fixing plate 804 on the top of the slider 802 moves toward the middle, clamping the pipe to achieve the fixation of the pipe. Conversely, rotating the screw 801 in the opposite direction can loosen the fixing plate 804 and release the fixation of the pipe. It should be noted that the purpose of fixing the first pipe 1 and the second pipe 2 is to facilitate the docking of the first pipe 1 and the second pipe 2 during installation, which plays a supporting role. If there is no support plate 6, someone needs to lift the first pipe 1 and the second pipe 2 to the appropriate height, and someone else needs to fix them, which makes the labor intensity high.

[0034] The above description of the disclosed embodiments will enable one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
