DETAILED DESCRIPTION

[0032] The following will be combined with the attached Figure 1-6 The present invention is further illustrated by the following embodiments.

[0033] Embodiment 1

[0034] This embodiment discloses a quick connection structure of a pipeline, which is used to connect two independent pipelines.

[0035] Reference Figure 1 and Figure 2 The quick connection structure of the pipeline includes a first pipe head 11, a second pipe head 12, a first clamp 21, a second clamp 22 and a buckle. The first pipe head 11 and the second pipe head 12 are respectively connected to the pipe ends of two different pipes. The first clamp 21 and the second clamp 22 are respectively clamped on the first pipe head 11 and the second pipe head 12. Specifically, the first clamp 21 and the second clamp 22 are respectively embedded in the first pipe head 11 and the second pipe head 12. There are multiple buckles, which are arranged between the first clamp 21 and the second clamp 22. Further, the buckle includes a loop 31 and a hook. In this embodiment, the loop 31 is arranged on the first clamp 21, and the second clamp 22 also serves as a hook. The advantage is that when the first pipe head 11 and the second pipe head 12 are connected by the buckle, there is no need to align the buckle, that is, the loop 31 can be overlapped at any position of the second clamp 22 as a hook, so as to achieve the effect of convenient and quick connection. It should be noted that, in the present embodiment, the first clamp 21 is embedded in the first pipe head 11 , and the second clamp 22 is embedded in the second pipe head 12 .

[0036] Reference Figure 3 and Figure 4 A first abutting end is provided at the end of the first tube head 11, and a second abutting end is provided inside the second tube head 12, wherein a sealing ring 4 is embedded in the end face of the second abutting end. After the first tube head 11 and the second tube head 12 are connected, the first abutting end abuts against the second abutting end, and sealing is achieved through the sealing ring 4.

[0037] Embodiment 2

[0038] This embodiment also discloses a quick connection structure of a pipeline, which is used to connect two independent pipelines.

[0039] Reference Figure 5The quick connection structure of the pipeline includes a first pipe head 11, a second pipe head 12, a first clamp 21, a second clamp 22 and a buckle. The first pipe head 11 and the second pipe head 12 are respectively welded to the pipe ends of two different pipes, the first clamp 21 and the second clamp 22 are respectively clamped on the first pipe head 11 and the second pipe head 12, and a plurality of buckles are provided, each buckle includes a loop 31 and a hook 32, a plurality of loops 31 are arranged around the outer wall of the first clamp 21, and a plurality of hooks 32 are arranged around the outer wall of the second clamp 22, and the plurality of loops 31 are used to overlap the plurality of hooks 32 in a one-to-one correspondence. In the present embodiment, the buckle is a built-in spring buckle. In the remaining embodiments, other types of buckles can also be selected as long as the overlap locking can be achieved. The connection principle of the buckle is the prior art, so it will not be described in detail. Through the above arrangement, when connecting two different pipes, the connection can be achieved by simply bending the buckle ring 31. Compared with the flange connection method between pipes in the prior art, the present invention can achieve quick connection, making it easy to deal with the situation of pipe connection that requires frequent disassembly and assembly.

[0040] Reference Figure 5 and Figure 6 A groove is provided between the outer edges of the end faces of the butt joint ends of the first tube head 11 and the second tube head 12, and a sealing ring 4 is embedded in the groove. The sealing ring 4 and the groove have an interference fit, so that when the first tube head 11 and the second tube head 12 are butt jointed, the sealing ring 4 can be squeezed into the groove, thereby improving the connection sealing between the first tube head 11 and the second tube head 12. In this embodiment, the sealing ring 4 is a rubber ring.

[0041] Reference Figure 5 and Figure 6If the distance between the loop 31 and the hook 32 of the buckle between the first tube head 11 and the second tube head 12 remains unchanged, that is, it is always kept at a distance that can be fastened, it is easy to cause the staff to have difficulty in overlapping the buckle, which is still not conducive to the rapid connection between the pipes. To this end, the hook 32 is movably arranged along the axial direction of the second tube head 12. Specifically, a slide groove 51 is provided on the outer wall of the second clamp 22, and a slider 52 is slidably arranged in the slide groove 51. The hook 32 is fixedly connected to the slider 52. The hook 32 is movably arranged on the second tube head 12 through the sliding cooperation between the slider 52 and the second tube head 12. Further, a plurality of first guide holes are provided between the two end faces of the first clamp 21, and a first guide rod 61 is movably arranged in the plurality of first guide holes. A first movable ring 62 is connected between one end of the first guide rod 61 facing the second clamp 22, so that the first movable ring 62 can move relative to the inner end face of the first clamp 21. A threaded hole is also provided between the two end faces of the first hoop 21, and a screw 63 is threadedly connected to the threaded hole. One end of the screw 63 is rotatably connected to the first moving ring 62, and the other end is fixedly connected to a screw block, so that the staff can control the movement of the first moving ring 62 by screwing the screw block and the screw 63. In this process, the first guide rod 61 plays a limiting effect, thereby converting the rotational movement of the screw 63 into the linear movement of the first moving ring 62. A second guide hole is provided between the end face of the slide 51 and the inner end face of the second hoop 22. A second guide rod 71 is movably provided in the second guide hole. One end of the second guide rod 71 is fixedly connected to the slider 52, and the other end extends out of the inner end face of the second hoop 22. A second moving ring 72 is connected between the outer ends of the plurality of second guide rods 71, and the second moving ring 72 is located on the moving path of the first moving ring 62. Through the above arrangement, when overlapping the buckle, the first movable ring 62 can be moved away from the second movable ring 72 first. At this time, the hook 32 has space close to the loop 31, avoiding that the hook 32 and the loop 31 are always kept at a fastening distance, which makes it easier for the staff to overlap the buckle. After the buckle is overlapped, the first movable ring 62 is controlled to approach and push the second movable ring 72, and the second movable ring 72 drives the hook 32 to press the loop 31, thereby realizing the overlapping and locking.

[0042] Reference Figure 5 and Figure 6 A self-locking spring 8 is connected between the slider 52 and the end surface of the slide groove 51. The elastic force of the self-locking spring 8 makes the hook 32 automatically move away from the buckle. When the buckle is overlapped, the hook 32 can be automatically approached by the external force during the overlapping process, thereby saving effort to overlap. After the overlapping is completed, the hook 32 can be automatically moved away from the loop 31 by the elastic force of the self-locking spring 8, so that the distance between the hook 32 and the loop 31 is automatically maintained at a lockable distance, thereby preventing the loop 31 from easily separating from the hook 32 during the overlapping process of the buckle.

[0043] Reference Figure 5 and Figure 6 In order to further improve the sealing performance of the sealing ring 4, the outer edge of the sealing ring 4 is further arranged on the path where the first moving ring 62 approaches the second moving ring 72, so that when the first moving ring 62 approaches the second moving ring 72, the first moving ring 62 can press the sealing ring 4 in the radial direction, so that the inner wall of the sealing ring 4 can press the joint between the first tube head 11 and the second tube head 12, thereby further improving the sealing performance of the sealing ring 4. In addition, since the locking of the buckle and the pressing of the sealing ring 4 are both controlled by the first moving ring 62, the locking of the buckle and the pressing of the sealing ring 4 can be synchronously achieved by only controlling the rotation of the screw 63, thereby achieving the effect of convenient control.

[0044] Reference Figure 5 and Figure 6 In this embodiment, there are four buckles, four loops 31 and four hooks 32, respectively. Further, the loops 31 are connected to the outer wall of the first hoop 21 by screws 9, so that when one of the loops 31 fails, the first hoop 21 needs to be removed for overall replacement, and only the failed loop 31 needs to be removed and replaced, so as to achieve the effect of convenient maintenance. In addition, the first hoop 21 and the second hoop 22 are both tightened by bolts 23 and nuts.

[0045] This embodiment also discloses a quick connection method for pipelines.

[0046] Reference Figure 5 and Figure 6 , the quick connection method of the pipeline includes the following steps:

[0047] S1: The staff fixes and connects the first pipe head 11 and the second pipe head 12 to two different pipes respectively;

[0048] S2: The staff holds the first clamp 21 tightly on the first pipe head 11, and holds the second clamp 22 tightly on the second pipe head 12;

[0049] S3: The staff overlaps the multiple loops 31 on the first clamp 21 on the multiple buckles of the second clamp 22 in sequence. Before overlapping, the first movable ring 62 is separated from the second movable ring 72, and the first movable ring 62 is separated from the sealing ring 4. After overlapping, the first movable ring 62 is pressed against the second movable ring 72, and the first movable ring 62 is pressed against the sealing ring 4.

[0050] The above are all preferred embodiments of the present invention, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
