Description

Technical Field

[0001] This utility model belongs to the field of tracheal connection technology, and in particular relates to a tracheal connector. Background Technology

[0002] In existing technologies, air pipe connections are typically achieved using air pipe connectors. The connection process involves first selecting a suitable air pipe connector, then connecting one end of the connector to one air pipe via tightening or plugging, and finally connecting the other end of the connector to the other air pipe, allowing for smooth gas flow between the two pipes. Therefore, air pipe connectors, as core transmission components of pneumatic systems, are widely used in the internal air circuit layout of electrical cabinets, integrated installation of air circuit valve islands, and actuators such as mechanical grippers.

[0003] However, in practical applications, air pipe connections often require multi-way installation, and each air pipe connector needs to be fixed in position using clamps or other fasteners. This results in cumbersome installation and poor space adaptability, making it difficult to meet the space-constrained requirements of electrical cabinets and valve island integration scenarios. Therefore, there is an urgent need to develop an air pipe connector that is compact in structure, easy to install, convenient to connect, and suitable for multi-way air pipe connections. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing technology by providing a reasonably designed, compact, easy-to-install, and conveniently connected air pipe connector suitable for multi-line air pipe connections.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air tube connector includes a housing and an air tube fitting. The housing has multiple independent gas channels inside. One end of each gas channel is detachably connected to a multiple air tube fitting. The other end of each gas channel is fixedly connected to a multiple quick-connect fitting, which is a quick-connect male or a quick-connect female.

[0007] Preferably, the quick-connect female connector includes a receiving interface and a limiting ring. The receiving interface is integrally formed and connected to the other end of the gas channel. The limiting ring protrudes inward into the other end of the gas channel. A gas stop block for controlling the gas flow is slidably inserted inside the limiting ring. A spring is provided between the gas stop block and the gas pipe connector.

[0008] Preferably, the gas stop block is T-shaped, with the outer diameter of one end of the gas stop block being larger than the inner diameter of the limiting ring and smaller than the inner diameter of one end of the gas channel, and the outer diameter of the other end of the gas stop block being smaller than the inner diameter of the limiting ring.

[0009] Furthermore, a sealing ring is provided between the air stop block and the limiting ring.

[0010] Furthermore, a sealing groove is provided at the other end of the air stop block, and a sealing ring is embedded in the sealing groove.

[0011] Preferably, the quick-connect male connector includes a plug and a limiting groove. The plug has a hollow structure. One end of the plug is integrally formed and connected to the other end of the gas channel. The other end of the plug has a push-up end face. The limiting groove is formed on the periphery of one end of the plug.

[0012] The quick-connect male connector is integrally molded and connected to the other end of the gas channel.

[0013] Preferably, the inner wall of one end of each of the multiple gas channels is provided with an internal thread, which is threaded to the external thread provided at one end of the gas pipe connector.

[0014] Furthermore, each of the multiple gas channels has a guide port at one end.

[0015] Furthermore, a heat dissipation channel is provided between each two adjacent gas channels, and the heat dissipation channel is not connected to the gas channel.

[0016] Furthermore, two mounting bosses are provided on each of the opposite sides of the housing.

[0017] This utility model adopts the above technical solution and has the following technical effects:

[0018] This invention, through its housing, multiple air pipe connectors, and multiple quick-connect connectors, not only allows for the rapid connection of multiple air pipes to ensure unimpeded gas flow and good spatial adaptability, but also allows the housing to be used to centrally locate multiple air pipe connectors, so that only the housing needs to be fixed in position during installation. This overcomes the cumbersome installation problem of air pipe connectors in the prior art, improves installation efficiency, and offers good space compactness, which is conducive to product miniaturization. In addition, the quick-connect connectors allow for the rapid connection of air pipe connectors with quick-connect males to those with quick-connect females, making the usage more flexible.

[0019] This utility model has a compact structure, is easy to install and connect, and is suitable for multi-line air pipe connection. It can meet the space requirements for air pipe connection in electrical cabinet and valve island integration scenarios. Attached Figure Description
