[0017] The utility model will be described in detail in combination with the drawings and examples.

[0018] A double head joint, such as Figure 1 And Figure 2As shown, including the joint body 1, the joint body 1 center is provided with flow through slot 2, flow through slot 2 through the length direction of the joint body 1, the two sides of the joint body 1 are provided with ring groove 3, the inner diameter of ring groove 3 is greater than the diameter of flow through slot 2, the inner wall of guide groove 9 on the inner wall of ring groove 3 towards flow through slot 2, the distance between the inner wall of guide groove 9 and the center of flow through slot 2 is smaller, the closer to the opening of ring groove 3, the installation groove 10 is provided on the inner wall of guide groove 9, the sealing ring 11 is installed in the installation groove 10, the cross section of installation groove 10 is arc-shaped, by setting guide groove 9, the space of ring groove 3 opening position is relatively large, so that people can slide the sealing strip along the inner wall of guide groove 9 and embed it into installation groove 10, which is convenient for the installation of sealing ring 11.

[0019] As shown in Figure 1 and Figure 2 , the outer wall of the joint body 1 is provided with observation hole 4 which is communicated with ring groove 3, the setting of observation hole 4 makes people can directly observe one end of the deepest part of ring groove 3 through observation hole 4, so as to judge whether the pipeline is screwed in place, the distance from the center of observation hole 4 to the opening of ring groove 3 is equal to the depth of ring groove 3, so that the plane where the bottom wall of ring groove 3 is located passes through the center position of observation hole 4, that is, the contact surface between the side wall of the pipeline and the inner wall of ring groove 3 passes through the center of observation hole 4, so as to facilitate people to observe whether the pipeline is in contact with the bottom wall of ring groove 3, the end of observation hole 4 away from ring groove 3 is provided with transparent sealing plate 5, which does not affect the observation of people, but also can prevent dust from entering the double head joint through observation hole 4.

[0020] As shown in Figure 1 and Figure 2 , because the outer wall of the joint body 1 is hexagonal, a wrench is needed to clamp the joint body 1 during tightening the double head joint, the distance between the side of sealing plate 5 away from flow through slot 2 and the outer wall of flow through slot 2 makes the wrench not easy to contact with sealing plate 5, which ensures the safety of sealing plate 5, observation hole 4 includes mounting hole 6, transition hole 7 and communication hole 8, communication hole 8 is communicated with ring groove 3, sealing plate 5 is installed in mounting hole 6, the two ends of transition hole 7 are communicated with mounting hole 6 and communication hole 8 respectively, the diameter of transition hole 7 is larger, the closer to mounting hole 6, the diameter of mounting hole 6 is larger than that of communication hole 8, the larger diameter of mounting hole 6 makes more light enter the observation hole, the diameter of communication hole 8 is small, which reduces the influence on the internal thread on the inner wall of ring groove 3, ensures the engagement strength between the internal thread and the pipeline, and the transition hole 7 plays a guiding role for the incident light.

[0021] As shown in Figure 2As shown, the number of observation holes 4 in communication with the same ring groove 3 is two, and the two observation holes 4 are respectively located on the opposite two outer side walls of the joint body 1, so that no matter where the joint body 1 rotates, there is always one observation hole 4 that is relatively upward, facilitating people to observe, and the number is not more than two in order to reduce the process flow of manufacturing the double-head joint, the distance between the two observation holes 4 facing one end is greater than the inner diameter of the ring groove 3 and less than the outer diameter of the ring groove 3, so that the bottom of the observation hole 4 and the inner peripheral wall of the ring groove 3 facing the flow-through groove 2 have a certain distance, when the pipe is not screwed in place, the part of the observation hole 4 above the ring groove 3 and the part not above the ring groove 3 will have a difference, the part of the observation hole 4 above the ring groove 3 is recessed, when the pipe is screwed in place, the pipe will protrude in the part of the observation hole 4 above the ring groove 3, through the comparison of the difference of the two cases, whether the pipe is in place can be easily judged.

[0022] The preferred embodiments of the present application are described above, the protection scope of the present application is not limited to the above-mentioned embodiments, any technical solutions falling within the idea of the present application shall fall within the protection scope of the present application. It should be noted that for ordinary skilled in the art, some improvements and decorations without departing from the principles of the present application shall also be considered as falling within the protection scope of the present application.
