Description

Technical Field

[0001] This utility model relates to the technical field of tracheal connection devices, specifically to a quick-connect tracheal connector that facilitates connection. Background Technology

[0002] In deep-sea exploration equipment, the air tubes need to maintain a stable connection and seal under high pressure.

[0003] Traditional quick-connect endotracheal connectors are prone to deformation of their internal sealing structure after prolonged exposure to high pressure in the deep sea, leading to loose connections, gas leaks, and disruptions to normal equipment operation. In aerospace equipment, endotracheal connectors must not only withstand extreme temperature changes but also avoid the impact of electromagnetic interference on connection stability. Existing quick-connect endotracheal connectors are susceptible to induced currents in their internal metal components when exposed to strong electromagnetic environments, which can damage the connection structure and cause the endotracheal tube to detach. Furthermore, in some industrial automated production lines, ordinary connectors are prone to jamming during frequent insertion and removal of endotracheal tubes, significantly impacting production efficiency. Utility Model Content

[0004] In view of the problems existing in the above-mentioned quick-connect endotracheal connectors, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a quick-connect tracheal connector that is easy to connect, which solves the problem that the internal sealing structure is prone to deformation after being subjected to high pressure in the deep sea for a long time.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A quick-connect endotracheal connector for easy connection includes a plug body and a socket body. One end of the plug body is snapped into the socket body. Two annular grooves are formed on the outer side wall of the plug body. An elastic sealing ring is fixedly installed in the two annular grooves. One end of the plug body is provided with a guide lip. An endotracheal tube is fixedly installed at one end of the plug body and one end of the socket body. Two annular protrusions are fixedly installed on the inner side wall of the socket body. The annular protrusions correspond to the annular grooves in position and are adapted in size.

[0008] Preferably, a first magnetic ring is fixedly provided at the insertion end of the plug body, and a second magnetic ring is fixedly provided on the inner side wall of the socket body.

[0009] Preferably, the first magnetic ring and the second magnetic ring are permalloy rings.

[0010] Preferably, the plug body has a gas flow channel inside, which is connected to the inside of the connected air pipe.

[0011] Furthermore, both the plug body and the socket body are hollow tubular.

[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0013] 1. This utility model, through the design of the guide lip, enables the plug body to be quickly and accurately inserted into the socket body; the setting of the first magnetic ring and the second magnetic ring utilizes magnetic force to achieve rapid alignment and initial fixation of the plug body and the socket body, which greatly improves the efficiency of the air tube connection; the cooperation of the annular protrusion and the annular groove, combined with the elastic sealing ring, forms a multi-seal structure, which can effectively prevent gas leakage under high pressure environment and ensure the airtightness of the air tube connection.

[0014] 2. This utility model adopts a magnetic auxiliary connection mechanism made of non-ferromagnetic soft magnetic material, which can avoid interference in strong electromagnetic environments and ensure the connection stability of the joint in strong electromagnetic environments such as aerospace; the multiple sealing structure also enables the joint to adapt to harsh environments such as deep sea high pressure.

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0022] This utility model discloses a quick-connect endotracheal connector that is easy to connect.

[0023] This utility model provides, for example Figure 1-3 The quick-connect endotracheal connector shown includes a plug body 1 and a socket body 2. One end of the plug body 1 is snapped into the socket body 2. Two annular grooves 3 are formed on the outer wall of the plug body 1, and elastic sealing rings 4 are fixed within the two annular grooves 3. A guide lip 5 is provided at one end of the plug body 1. An endotracheal tube 6 is fixed to one end of the plug body 1 and the other end of the socket body 2. Two annular protrusions 7 are fixed to the inner wall of the socket body 2. The annular protrusions 7 correspond in position and are sized to the annular grooves 3, suitable for connecting endotracheal tubes 6 made of soft materials such as rubber. The clamping force tightly fixes the endotracheal tube 6 to the plug body 1 or socket body 2. Heat fusion connection is suitable for some plastic endotracheal tubes 6. Heating melts and fuses the endotracheal tube 6 with the plastic at the connector, forming a strong connection. After connection, the operator holds the plug body 1, aligns its insertion end with the socket body 2's insertion hole, and, guided by the guide lip 5... The plug body 1 can be smoothly and accurately inserted into the socket. When the plug body 1 is inserted to a certain depth, the first magnetic ring 8 set at the insertion end of the plug body 1 and the second magnetic ring 9 set at the bottom of the socket 2 begin to attract each other. Under the action of magnetic force, the plug body 1 and the socket body 2 can be quickly aligned and initially fixed. At this time, continue to insert the plug body 1 until the annular protrusion 7 is embedded in the annular groove 3 and tightly fits with the elastic sealing ring 4. Thus, the quick, stable and sealed connection of the air tube 6 is completed. When it is necessary to disconnect the connection, the operator applies a certain external force to overcome the magnetic force between the first magnetic ring 8 and the second magnetic ring 9 and the sealing resistance between the elastic sealing ring 4 and the inner wall of the socket body 2, and the plug body 1 can be pulled out of the socket body 2. During the pulling process, care should be taken to avoid damaging the plug body 1, the socket body 2 and the elastic sealing ring 4, so that they can continue to be used normally in the future.

[0024] For a more stable connection, such as Figure 1 As shown, the plug body 1 has a first magnetic ring 8 fixedly installed at the insertion end, and the socket body 2 has a second magnetic ring 9 fixedly installed on the inner side wall.

[0025] And for greater durability, such as Figure 1-2 As shown, the first magnetic ring 8 and the second magnetic ring 9 are made of permalloy.

[0026] And for better connectivity, such as Figure 1 As shown, a gas guide channel 10 is provided inside the plug body 1, and the gas guide channel 10 is connected to the inside of the connected air pipe 6.

[0027] Finally, for easier connection, such as Figure 1-2 As shown, both the plug body 1 and the socket body 2 are hollow tubular.

[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
