DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Reference Figure 1-7, the utility model provides an embodiment: a pipeline connection mechanism, including a main pipeline 1, one end of the main pipeline 1 is provided with a connecting pipe 2, one end of the main pipeline 1 is sleeved with a first pressure plate 3, the first pressure plate 3 is fixedly connected to the main pipeline 1, one end of the connecting pipe 2 is sleeved with a second pressure plate 4, one end of the first pressure plate 3 is in contact with one end of the second pressure plate 4, the second pressure plate 4 is rotatably connected to the connecting pipe 2, the main pipeline 1 is connected to the connecting pipe 2 through the first pressure plate 3 and the second pressure plate 4, the outer ring of the first pressure plate 3 is provided with a first connecting groove 5, the outer ring of the second pressure plate 4 is provided with a second connecting groove 6, a connecting mechanism 7 is provided on the first pressure plate 3, and the first connecting groove 5 and the second connecting groove 6 are both provided corresponding to the connecting mechanism 7;

[0026] The connecting mechanism 7 includes a fixed seat 71, a rotating rod 72, a threaded connecting rod 73, a rotating block 74 and a fixed handle 75. The fixed seat 71 is fixedly connected to the other end of the first pressure plate 3. The rotating rod 72 is arranged between the fixed seats 71 and is rotatably connected to the fixed seat 71. The threaded connecting rod 73 is arranged inside the first connecting groove 5. One end of the threaded connecting rod 73 passes through the rotating rod 72 and is threadedly connected thereto. The other end of the threaded connecting rod 73 extends to the other end of the second pressure plate 4 through the second connecting groove 6. The rotating block 74 is arranged above the other end of the second pressure plate 4. The rotating block 74 and the second pressure plate 4 are movably connected. The other end of the threaded connecting rod 73 is rotatably connected to the bottom of the rotating block 74. The fixed handle 75 is arranged above the second pressure plate 4 and the first connecting groove 5. The fixed handle 75 is fixedly connected to the upper side of the rotating block 74.

[0027] Through the above technical solution, by setting up a connecting mechanism 7, by pulling the fixed handle 75, the rotating block 74 is driven to rotate with the connection position between the fixed seat 71 and the rotating rod 72 as the center point, and the rotating block 74 is placed on the other end of the second pressure plate 4. By pressing the fixed handle 75, the rotating block 74 is driven to rotate with the connection between the threaded connecting rod 73 and the rotating block 74 as the center point. Since the threaded connecting rod 73 and the rotating block 74 are set to an eccentric connection, the rotating block 74 can be made to conflict with the second pressure plate 4, so as to disguise the tight fit between the first pressure plate 3 and the second pressure plate 4, so as to connect the main pipeline 1 with the connecting pipe 2.

[0028] Specifically, one end of the first pressure plate 3 is fixedly connected to a guide rod 10 , one end of the second pressure plate 4 is provided with a guide groove 11 , and the guide rod 10 is slidably connected to the second pressure plate 4 through the guide groove 11 .

[0029] Through the above technical solution, by setting the guide rod 10 and the guide groove 11, and by aligning the guide groove 11 on the second pressure plate 4 with the guide rod 10 on the first pressure plate 3, the position of the second pressure plate 4 can be guided and limited, so as to facilitate the staff to subsequently connect the main pipeline 1 and the connecting pipe 2.

[0030] Specifically, a placement groove 12 is opened at one end of the first pressure plate 3 , and a sealing ring 13 is provided at one end of the first pressure plate 3 . The sealing ring 13 is embedded in the first pressure plate 3 through the placement groove 12 .

[0031] Through the above technical solution, by providing the sealing ring 13, the sealing between the main pipe 1 and the connecting pipe 2 can be increased to prevent liquid from leaking from the connection between the main pipe 1 and the connecting pipe 2.

[0032] Specifically, both sides of the lower portion of the rotating block 74 are configured as arc-shaped surfaces, and an eccentric connection is configured between the threaded connecting rod 73 and the rotating block 74 .

[0033] Through the above technical solution, both sides of the lower side of the rotating block 74 are set as arc-shaped surfaces. Since the arc-shaped surfaces are guiding, the staff can easily rotate the rotating block 74. The threaded connecting rod 73 and the rotating block 74 are set to be eccentrically connected. By rotating the rotating block 74, a small part of the threaded connecting rod 73 can be pulled into the interior of the rotating block 74 to indirectly change the length of the threaded connecting rod 73, so that the first pressure plate 3 and the second pressure plate 4 can fit tightly.

[0034] Specifically, four connecting mechanisms 7 are provided, and the four connecting mechanisms 7 are all provided at the other end of the first pressure plate 3 and are evenly distributed.

[0035] Through the above technical solution, the above connecting mechanism 7 is evenly distributed, which can prevent the deviation of the position of the force exerted by the connecting mechanism 7 on the first pressure plate 3 and the second pressure plate 4, resulting in one side of the first pressure plate 3 and the second pressure plate 4 being compacted and the other side being slightly tilted, thereby preventing liquid leakage.

[0036] Specifically, a groove 8 is provided above the threaded connecting rod 73 , and a scale mark 9 is provided inside the threaded connecting rod 73 through the groove 8 .

[0037] Through the above technical solution, by setting the scale mark 9, the staff can accurately change the length of the threaded connecting rod 73 between the rotating rod 72 and the rotating block 74, so that the forces acting on the four connecting mechanisms 7 are the same, preventing liquid leakage due to different forces acting on the connecting mechanisms 7.

[0038] Working principle: When in use, first align the guide groove 11 on the second pressure plate 4 with the guide rod 10 on the first pressure plate 3 to guide and limit the connection position between the second pressure plate 4 and the first pressure plate 3, and then change the length of the threaded connecting rod 73 between the rotating rod 72 and the rotating block 74 by rotating the threaded connecting rod 73. When the length of the threaded connecting rod 73 is sufficient, pull the fixed handle 75 to drive the rotating block 74 to rotate around the connection position between the fixed seat 71 and the rotating rod 72, and place the threaded connecting rod 73 inside the first connecting groove 5 on the first pressure plate 3 and the second connecting groove 6 on the second pressure plate 4, so that the rotating block 74 is placed on the other end of the second pressure plate 4. Then, when the rotating block 74 rotates to the other end of the second pressure plate 4 Then, the threaded connecting rod 73 is rotated again according to the scale mark 9 to shorten the length of the threaded connecting rod 73 between the rotating rod 72 and the rotating block 74. Then, by pressing the fixed handle 75, the rotating block 74 is driven to rotate with the connection between the threaded connecting rod 73 and the rotating block 74 as the center point. Since the threaded connecting rod 73 and the rotating block 74 are set to be eccentrically connected, the rotating block 74 can be made to conflict with the second pressure plate 4, thereby making the first pressure plate 3 and the second pressure plate 4 fit tightly in disguise, thereby connecting the main pipe 1 with the connecting pipe 2. At the same time, the other connecting mechanisms 7 are operated in turn through the above steps, and it is necessary to make the lengths of the threaded connecting rods 73 on the four connecting mechanisms 7 the same through the scale mark 9.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
