[0016] The specific implementation of the utility model is described in detail below in combination with the preferred embodiments and the drawings.

[0017] As Figure 1 , Figure 4 and Figure 5 Indicated, a kind of gas path quick switching mechanism, including fixed end support 1, fixed end quick -plug mounting plate 2, movable end quick -plug plate 3, transition plate 4, double guide rod cylinder 5 and sealing ring 6, the piston rod of the cylinder is connected with the movable end quick -plug plate by the transition plate, moves by cylinder and drives movable segment quick -plug plate, realizes the closing and separation work of fixed end quick -plug mounting plate. Several gas inlets 7 are provided on the movable end quick -plug plate, specifically, the gas inlet is communicated with the gas inlet passage 9 located on movable end quick -plug mounting plate. The other end of the gas inlet passage is located at the both sides of movable block quick -plug plate, and the gas inlet passage is ventilated to gas inlet. In order to facilitate the installation of sealing ring, the sealing ring is embedded in the gas inlet, the fixed end quick -plug mounting plate is fixed on the fixed end support, the fixed end quick -plug mounting plate is provided with exhaust hole 8 corresponding to the gas inlet, and the exhaust hole is used for the gas supply for fixed equipment.

[0018] As Figure 2 Indicated, sealing ring mounting groove 10 is provided on the movable end quick -plug plate, and the sealing ring is mounted in the sealing ring mounting groove.

[0019] As Figure 3 Indicated, cavity 11 is arranged in the sealing ring, and inlet 12 and outlet 13 are arranged at both ends of the cavity, wherein the inner diameter of the inlet is same with the inner diameter of the gas inlet, and the outlet is provided with annular protrusion.

[0020] After the double guide rod cylinder is extended, the movable end quick plug plate and the fixed end quick plug plate are in close contact, the sealing ring is deformed under the pressure of the movable end quick plug plate and the fixed end quick plug plate, the sealing gasket is deformed by extrusion to ensure that a closed space is formed between the movable end quick plug plate and the fixed end quick plug plate, so that the compressed air is normally delivered from the movable end quick plug plate to the fixed end quick plug plate, and to the clamp.

[0021] It should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered within the scope of the present application.
