Example 2
[0050] This embodiment provides a pipeline connection device. This embodiment is optimized based on the first embodiment to improve the technical effect and refine the technical solution. For details not fully described in this embodiment, please refer to the first embodiment.
[0051] As one embodiment, the female interface 1 is provided with a first internal thread matching the first external thread 3.1, and the first external thread 3.1 is screwed into the first internal thread to connect the male interface 3 to the female interface 1. The first external thread 3.1 can be designed to be deeper, refer toFigure 6 The deeper first external thread 3.1 meets the threaded connection of the female interface 1 and the second anti-lost ring 4.3 at the same time.
[0052] As one of the embodiments, the first external profile 1.1 and the inner profile 2.4.1 are both polygons, and the edges of the polygons can reduce the probability of the first anti-lost ring 2.4 being pulled out of the first external profile 1.1. The polygon can be a hexagon, which is convenient for the operation of a wrench.
[0053] The first anti-lost ring 2.4 is not limited to being set on the first external profile 1.1 to prevent loss, and referring to Figure 1 , Figure 5 and Figure 6 , the female interface 1 further includes a thin neck 1.2 which is thinner than the first external profile 1.1, and the first anti-lost ring 2.4 is hung on the thin neck 1.2 by gravity after passing through the first external profile 1.1. The first anti-lost ring 2.4 needs harsh conditions to be pulled out of the first external profile 1.1, which needs to overcome the gravity to be lifted to the height corresponding to the first external profile 1.1, and then ensure that the inner profile 2.4.1 corresponds to the polygon angle of the first external profile 1.1. Obviously, in addition to human operation, it is difficult to meet these two conditions at the same time due to various shaking. As one of the embodiments, the female interface 1 is in communication with the first pipeline component 5, and the thin neck 1.2 is a connecting transition component between the first external profile 1.1 and the first pipeline component 5.
[0054] As one of the embodiments, referring to Figure 2 , Figure 5 and Figure 6 , the male interface 3 further includes a first thick neck 3.2 adjacent to the first external thread 3.1, the first thick neck 3.2 is thicker than the radius of the first external thread 3.1, and after the second anti-lost ring 4.3 is screwed into the first external thread 3.1, the first thick neck 3.2 abuts against the second anti-lost ring 4.3 to prevent the second anti-lost ring 4.3 from being excessively penetrated into the male interface 3, and when the female interface 1 or the female plug 4 is connected with the male interface 3, the female interface 1 or the female plug 4 can clamp the second anti-lost ring 4.3 with the first thick neck 3.2 to prevent the second anti-lost ring 4.3 from shaking, or make the second anti-lost ring 4.3 play the role of a gasket.
[0055] As one of the embodiments, a third internal thread is arranged in the female plug 4, and referring to Figure 3 , the male plug 2 includes a second external thread 2.1 matched with the third internal thread, and the male plug 2 and the female plug 4 can be connected with each other through the threaded cooperation of the third internal thread and the second external thread 2.1, which not only makes the connection more firm, but also protects the thread structure and the sealing structure of each other. The third internal thread can also be used for the connection between the female plug 4 and the male interface 3, that is, the third internal thread is matched with the first external thread 3.1, and the second external thread 2.1 can also be used for the connection between the male plug 2 and the female interface 1, that is, the second external thread 2.1 is matched with the first internal thread.
[0056] As one of the embodiments, the male plug 2 also comprises a second thick neck 2.2 adjacent to the second external thread 2.1, the second thick neck 2.2 is thicker than the radius of the second external thread 2.1, referring to Figure 5 With Figure 6 , the second thick neck 2.2 will prevent the male plug 2 from being inserted into the female interface 1 or the female plug 4 too much.
[0057] It is worth noting that since the male plug 2 is connected to the female interface 1 or the female plug 4 by threaded connection, the connection point of the first connecting rope 2.3 with the male plug 2 is set at the second thick neck 2.2, and the first connecting rope 2.3 is away from the second external thread 2.1, preventing the first connecting rope 2.3 from being stuck in the thread when the male plug 2 is rotated.
[0058] As one of the embodiments, the end of the male plug 2 away from the second external thread 2.1 is rotationally connected with the first connecting rope 2.3, and the end of the female plug 4 away from the third internal thread is rotationally connected with the second connecting rope 4.1, in addition to avoiding the connecting rope being stuck in the thread, it also prevents the first connecting rope 2.3 or the second connecting rope 4.1 from being wound too much when the male plug 2 or the female plug 4 is screwed in / out by rotating the control thread. The rotational connection can be achieved by setting a micro bearing connected with the first connecting rope 2.3 or the second connecting rope 4.1 at the second thick neck 2.2 of the male plug 2 or the end of the female plug 4 away from the third internal thread.
[0059] As one of the embodiments, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , the pipeline connecting device provided by the embodiment further comprises a first hanging card 2.5 provided on the first connecting rope 2.3 and a second hanging card 4.2 provided on the second connecting rope 4.1, and the first hanging card 2.5 and the second hanging card 4.2 are both provided with mutually corresponding identifiable codes. The application of identifiable codes can quickly find the corresponding female interface 1 and male interface 3 when connecting multiple pipelines. The identifiable codes include two-dimensional codes, three-dimensional codes or natural languages.
[0060] As one of the embodiments, the second thick neck 2.2, the outer surface of the female plug 4 and the first thick neck 3.2 are polygons matching the first external contour 1.1, including hexagons, which are convenient for wrench control rotation.
[0061] As one of the embodiments, referring to Figure 3 , the first anti-lost ring 2.4 is provided with a hole 2.4.2 for the first connecting rope 2.3 to pass through, and the position of the hole 2.4.2 avoids the edges and corners of the inner contour 2.4.1.
[0062] As one of the embodiments, the thickness of the first anti-lost ring 2.4 and the second anti-lost ring 4.3 can be adjusted as required.
[0063] Compared with the first embodiment, the pipeline connecting device provided by the embodiment improves the sealing performance and use convenience. Embodiment three
