DETAILED DESCRIPTION

[0026] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0027] Embodiment 1

[0028] refer to Figures 1 to 5 This embodiment provides a joint for gas and electric pipelines, including a first joint, a second joint, an air pipe 3 and an electric wire pipe 4. The first joint and the second joint are respectively provided with openings. The air pipe 3 and the electric wire pipe 4 pass through the first joint and the second joint through the openings and are mounted inside the first joint and the second joint.

[0029] The air pipe 3 passes through the first joint and the second joint, and the two air pipes 3 are connected in the first joint or the second joint; the electric wire tube 4 also passes through the first joint and the second joint, and the two electric wire tubes 4 are connected in the first joint or the second joint.

[0030] At the same time, there will be corresponding components in the first joint and the second joint to fix the air pipe 3 and the electric wire pipe 4 after docking, so that the air pipe 3 and the electric wire pipe 4 can be firmly installed inside the first joint and the second joint.

[0031] In this embodiment, the first joint includes a left end cover 11 and a right end cover 12 , which together form a first internal space 18 , and a fixing member 13 is disposed in the first internal space 18 to fix the air pipe 3 and the electric wire pipe 4 .

[0032] On the one hand, the fixing member 13 can fix the trachea 3 and the electric wire tube 4 to ensure that the trachea 3 and the electric wire tube 4 can be firmly fixed, and on the other hand, it can also realize the docking between the trachea 3 and the trachea 3 and the docking between the electric wire tube 4.

[0033] In this embodiment, the fixing member 13 includes a rubber sleeve, a snap buckle, etc. For example, the rubber sleeve allows the pipelines to be seamlessly connected to prevent leakage, and the snap buckle is used to further fix the pipeline and the joint of the pipeline to prevent the pipeline from deflecting.

[0034] The second joint includes an upper cover 21 and a lower cover 22, which together form a second internal space 19. A sleeve 24 and a movable clamp 25 are provided in the second internal space 19. The sleeve 24 is sleeved on the air pipe 3, and one end of the movable clamp 25 is clamped on the electric wire pipe 4, and the other end is clamped on the sleeve 24.

[0035] The sleeve 24 is used to achieve the docking between the trachea 3 and the trachea 3, and the movable clamp 25 is detachable. After the wire tube 4 is docked with the wire tube 4, one end of the movable clamp 25 fixes the docking point, and the other end of the movable clamp 25 fixes the docking point between the trachea 3 and the trachea 3, thereby ensuring that the trachea 3 and the wire tube 4 can be firmly fixed in the second internal space 19 of the second joint, and also ensuring the reliability of the docking.

[0036] The connection between the electric wire tubes 4 is a conventional connection, for example, a rubber heat shrink tube is used to achieve the connection.

[0037] In this embodiment, a bolt hole 211 is provided on the upper surface of the upper cover 21, and a first hole column 221 is provided on the inner surface of the lower cover 22. A first bolt is inserted into the bolt hole 211, and the first bolt is screwed into the first hole column 221 to connect the lower cover 22 with the upper cover 21.

[0038] Specifically, the upper cover 21 and the lower cover 22 need to be connected together by a first bolt to form a second internal space 19. Except for the openings for the air pipe 3 and the electric wire tube 4 to enter and exit, the second internal space 19 is a closed space, which can be isolated from the outside world and prevent external influences, such as dustproof and waterproof.

[0039] In this embodiment, a fixing hole 251 is provided on the movable clamp 25, and a second hole column 223 is provided on the lower cover 22. A second bolt is inserted into the fixing hole 251, and the second bolt is screwed into the second hole column 223 to fix the movable clamp 25 on the lower cover 22.

[0040] The movable clamp 25 is detachable. When the air pipe 3 is docked with the air pipe 3 and the electric wire pipe 4 is docked with the electric wire pipe 4, the two ends of the movable clamp 25 are respectively clamped at the docking points. The fixing hole 251 is located in the middle of the movable clamp 25. The movable clamp 25 is fixed by the second bolt, thereby firmly clamping the air pipe 3 and the electric wire pipe 4.

[0041] In this embodiment, a plurality of slots 212 and 222 are respectively provided on the inner surface of the upper cover 21 and the inner surface of the lower cover 22 , and the air pipe 3 and the electric wire pipe 4 are fixed by the slots 212 and 222 .

[0042] The card groove 212 and the card groove 222 mainly play the role of assisting fixation. The clamp mentioned above is mainly used to fix the joint of the pipeline in the second internal space 19, and the air pipe 3 and the electric wire pipe 4 run through the entire second internal space 19. The card groove 212 and the card groove 222 on the inner surface of the upper cover 21 and the inner surface of the lower cover 22 are also in the second internal space 19, so as to assist in fixing the air pipe 3 and the electric wire pipe 4.

[0043] The second joint is provided with openings for the air pipe 3 and the electric wire pipe 4 to enter and exit. The openings on the second joint include a first opening 23 and a second opening 232, which are respectively located on two side surfaces of the second joint.

[0044] The first opening 23 is arranged on the side of the lower cover 22, and the side of the lower cover 22 is one side of the second joint. The other side of the second joint is composed of the other side of the lower cover 22 and one side of the upper cover 21. The other side of the lower cover 22 has a semicircular opening, and one side of the upper cover 21 also has a semicircular opening. After the upper cover 21 is connected to the lower cover 22, the two semicircular openings are combined into a second opening 232.

[0045] A limiting portion 231 is disposed on the first opening 23 . One end of the limiting portion 231 is circular and sleeved on the sleeve 24 , and the other end is square.

[0046] After the air pipe 3 in the second internal space 19 comes out of the first opening 23 , in order to prevent the air pipe 3 from being damaged by external squeezing and collision at the first opening 23 , in this embodiment, a limiting portion 231 is provided to protect the air pipe 3 coming out of the first opening 23 .

[0047] A protective cover 241 is disposed on the second opening 232 . One end of the protective cover 241 is cylindrical, the other end is also cylindrical, and a polyhedral connecting portion is disposed in the middle. The connecting portion is disposed on the side of the lower cover 22 .

[0048] Similarly, the protective cover 241 at the second opening 232 is also used to protect the trachea 3 from being damaged by external squeezing and collision.

[0049] It should be understood that the calibers of the first opening 23 and the second opening 232 are the same, so as to ensure that the air pipe 3 can pass through the second joint unobstructed.

[0050] In this embodiment, the openings on the first joint include a first left opening 14, a second left opening 15, a first right opening 16 and a second right opening 17. The first left opening 14 and the second left opening 15 are located on the left end cover 11, and the first right opening 16 and the second right opening 17 are located on the right end cover 12.

[0051] The diameter of the first right opening 16 is greater than the diameter of the second right opening 17 .

[0052] The diameter of the first left opening 14 is also larger than the diameter of the second left opening 15 .

[0053] The first left opening 14 and the first right opening 16 are the inlet and outlet of the air pipe 3 . The air pipe 3 enters and exits the first inner space 18 through the first left opening 14 or the first right opening 16 .

[0054] The second right opening 17 and the second left opening 15 are the entrance and exit of the electric wire tube 4 . The electric wire tube 4 enters and exits the first inner space 18 through the second right opening 17 or the second left opening 15 .

[0055] The left end cover 11 is stepped, including two planes at different heights. The first left opening 14 is arranged on the plane with a higher height, and the second left opening 15 is arranged on the plane with a lower height. The stepped left end cover 11 increases the volume of the first internal space 18, making it easier to connect the pipelines.

[0056] By setting the first joint and the second joint, the air pipe and the electric wire pipe can be connected at the same time, which improves the connection efficiency and reduces the cost of the joint. It is suitable for occasions where multiple pipelines are connected. At the same time, due to the multiple joints, the reliability of the connection can also be guaranteed.

[0057] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
