Problems solved by technology

However, because the trachea needs to be inserted into the pressing ring, only the annular ring can be pressed when the pressing ring is pressed, and the actual pressing area for fingers or tools is small, and it is inconvenient to pull out the trachea while pressing. In addition, because the trachea connector is often installed in various occasions, the space in many occasions is limited, and when the trachea connector is small, it is more difficult to pull out the trachea while pressing

Embodiment Construction

[0030] the following to Figure 1 to Figure 11 Shown, the specific embodiment of the present invention is described.

[0031] Air tube 20 is generally a flexible round tube made of organic material. The outer diameter of the trachea 20 ranges from tens of mm to less than 1 mm. The trachea joint of the present invention is suitable for various trachea 20 with different outer diameters. Compared with the prior art, the trachea joint of the present invention only needs to rotate the inserted trachea 20, the trachea 20 can be pulled out; the operation of pulling out the trachea 20 is quicker and more convenient, especially for the small trachea 20 with an outer diameter of less than 5mm and the quick insertion or extraction of the trachea 20 in difficult-to-operate occasions.

[0032] Tracheal joint of the present invention such as figure 1 , figure 2 , image 3 As shown, a joint body 1 is included, an air channel 2 is opened in the joint body 1, and at least one port for in...

Abstract

The invention provides an air pipe joint comprising a joint body (1) which is internally provided with an air duct (2); the joint body (1) is provided with a mounting cavity (3) communicating with theair duct (2); the mounting cavity (3) is internally provided with a snap ring (6) of which the inner wall is provided with a clamping structure, and the snap ring (6) is provided with an inner wall external expansion deformation mechanism; and a deformation clearance is formed between the snap ring (6) and the mounting cavity (3). According to the air pipe joint, an air pipe is pulled out throughrotation of the air pipe, and the pullout operation of the air pipe is faster and more convenient, and can be performed by one hand; and particularly the convenience is provided for quick insertion or pullout of air pipes with small diameter and the air pipes that are hard to operate in occasions.

Description

technical field [0001] The invention relates to a trachea joint, in particular to a trachea joint which can be quickly inserted or pulled out of the trachea. Background technique [0002] Air pipe joints are widely used in pneumatic systems of various types of machinery. Existing trachea connectors are mainly ferrule-type trachea connectors that are pulled out by pressing, such as Figure 12 , Figure 13 As shown, this trachea joint includes a joint body, an airway is opened in the joint body, and at least one port for inserting the air supply tube is provided on the joint body, and an installation cavity with a diameter larger than the airway is provided at the port where the air supply tube is inserted. It communicates with the airway; the installation cavity is provided with a locking ring and a sealing ring, and the locking ring is provided with a plurality of locking pieces along its inner circumference, and the locking pieces are arranged obliquely relative to its inn...
