[0038] See also Figure 1In some embodiments, the utility model provides a joint assembly, including a joint 100 and a magnet 300. The joint 100 is a cylindrical shape with two ends open, one end of which is used to connect with the pipe 001, and the other end is used to connect with the interface equipped with the magnet 300. The magnet 300 is assembled on the outer wall of the middle section of the joint 100. When in use, one end of the pipe 001 is sleeved on one end of the joint 100, and the inner diameter of the pipe 001 matches the outer diameter of the joint 100. Adhesive can also be applied to the outer wall of one end of the joint 100 to make the connection state between the pipe 001 and the joint 100 more stable. The other end of the joint 100 is connected to the interface equipped with a magnet, and the magnet of the interface and the magnet 300 are attracted by magnetic force, so that the pipe 001 and the interface remain stable. In actual application, when the pipe 001 is pulled by a large external force, the joint assembly can automatically detach from the interface, which solves the technical problem in the prior art that the joint is difficult to detach from the interface when the pipe 001 is pulled by an external force. Avoid safety hazards caused by the equipment where the interface is located being pulled by pipe 001.
[0039] See also Figure 1 In some embodiments, the joint assembly further includes a first cylinder 200. The first cylinder 200 is a cylinder with one end open, and its inner diameter is larger than the outer diameter of the joint 100. A first through hole is opened at the other end of the first cylinder 200, and the first through hole is adapted to the outer diameter of the joint 100 and can accommodate the joint 100 passing through. The first cylinder 200 is sleeved on the middle section of the joint 100, and the edge of the first through hole is fixedly connected to the side wall of the joint 100. The inner wall of the first cylinder 200 and the outer wall of the joint 100 form a groove 210, and the magnet 300 is assembled in the groove 210.
[0040] See also Figure 2 In some embodiments, the connector assembly further includes an annular cover plate 400 having a second through hole 410 adapted to the connector 100 in the middle, and the cover plate 400 matches with an opening at one end of the first cylinder 200. When in use, the magnet 300 is first placed in the groove 210, and then the cover plate 400 is covered on the opening at one end of the first cylinder 200, and the cover plate 400 can fix the magnet 300 in the groove 210.
[0041] It should be noted that the magnet 300 may also be assembled in the groove 210 by other means, such as fixing with an adhesive, or providing a slot in the groove 210 to fix the magnet 300 therein.
[0042] Specifically, the cover plate 400 and the first cylinder 200 are both made of plastic, and the cover plate 400 is connected to an opening at one end of the first cylinder 200 by hot-melt connection.
[0043] It should be noted that the cover plate 400 and the opening at one end of the first cylinder 200 may also be connected by snap-fitting or fixed by adhesive.
[0044] Specifically, the connector 100 and the first cylinder 200 are both made of plastic, and the edge of the first through hole is connected to the side wall of the connector 100 by hot-melt connection.
[0045] It should be noted that the edge of the first through hole and the side wall of the connector 100 may be fixedly connected by adhesive, or the connector 100 and the first cylinder 200 may be produced as a whole by one-piece molding during the production process.
[0046] In some embodiments, the magnet 300 is a ring magnet adapted to the groove 210. No calibration is required when connecting to an interface equipped with a magnet, thereby improving work efficiency.
[0047] See also Figure 3 and Figure 4 In some embodiments, the joint assembly further includes a second cylinder 510, which is a cylinder with two ends open, and whose inner diameter is larger than the outer diameter of the joint 100. The second cylinder 510 is sleeved on one end of the joint 100 and fixedly connected to the first cylinder 200. The gap between the inner wall of the second cylinder 510 and the outer wall of the joint 100 is adapted to the pipe 001. When in use, after one end of the pipe 001 is sleeved on one end of the joint 100, one end of the pipe 001 enters the gap, so that the connection between the pipe 001 and the joint assembly is wrapped by the second cylinder 510, which can prevent the connection from being damaged during use and improve the stability of the connection between the pipe 001 and the joint assembly.
[0048] Furthermore, the second cylinder 510 has the same inner diameter as the first cylinder 200 . After one end of the second cylinder 510 is sleeved on one end of the joint 100 , the opening edge of one end of the second cylinder 510 is fixedly connected to the opening edge of one end of the first cylinder 200 .
[0049] It should be noted that other solutions can also be used to achieve a fixed connection between the second cylinder 510 and the first cylinder 200. For example, the inner diameter of the second cylinder 510 is 0.5 mm larger than the outer diameter of the first cylinder 200, and the inner wall of one end of the second cylinder 510 is fixed to the outer wall of the first cylinder 200 by an adhesive, or the inner wall of one end of the second cylinder 510 and the outer wall of the first cylinder 200 are provided with mutually matching threads, and fixed by threaded connection.
[0050] Furthermore, the first barrel 200 and the second barrel 510 are made of plastic, and an opening edge at one end of the second barrel 510 is connected to an opening edge at one end of the first barrel 200 by hot melting.
[0051] It should be noted that the opening edge at one end of the second cylinder 510 and the opening edge at one end of the first cylinder 200 can also be fixedly connected by adhesive.
[0052] See also Figure 5In some embodiments, the joint assembly includes a third barrel 520, which is a barrel with an open end, and its inner diameter is greater than the outer diameter of the joint 100. The other end of the third barrel 520 is provided with a third through hole 521 adapted to the joint 100. The third barrel 520 is sleeved on one end of the joint 100, and one end of the joint 100 passes through the third through hole 521 and enters the third barrel 520. The other end of the third barrel 520 is fixedly connected to the first barrel 200, or the edge of the third through hole 521 is fixedly connected to the side wall of the joint 100. The gap between the inner wall of the third barrel 520 and the outer wall of the joint 100 is adapted to the pipe 001. When in use, the third through hole 521 can make the assembly of the third barrel 520 more convenient, and no calibration is required during the assembly process. The inner diameter size of the third barrel 520 can be selected according to the pipe 001 with different wall thicknesses, and the end surface of the other end can provide a connection for its connection with the first barrel 200.
[0053] Further, the third barrel 520, the connector 100 and the first barrel 200 are all made of plastic, and the other end of the second barrel 510 is hot-melt connected to the first barrel 200, or the edge of the third through hole 521 is hot-melt connected to the side wall of the connector 100. It is understandable that a cross-linking agent can also be used to achieve a fixed connection between them.
[0054] It should be noted that the joint assembly including the second cylinder 510 and the joint assembly including the third cylinder 520 are two parallel solutions under the same concept.
[0055] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are illustrative and cannot be understood as limitations on the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
