The utility model discloses a magnesium alloy vacuum melting air passage connector which comprises a connector body, and an air passage is arranged in the connector body. The clamping opening is formed in the periphery of an outlet of the air channel; the clamping opening can be freely opened and closed. The beneficial effects of the utility model are that the periphery of the outlet of the air channel is provided with the clamping opening assembly which can be freely opened and closed, when the joint is connected with the to-be-tested workpiece, the clamping opening assembly is closed to clamp the near air port of the to-be-tested workpiece to prevent the joint from falling off, and the clamping opening sleeve is further moved to control the opening and closing of the clamping opening assembly, so that the joint is connected with the to-be-tested workpiece. When the joint is separated from the workpiece to be detected, the clamping opening sleeve slides backwards, and the clamping opening assembly is separated through fluctuation of concave-convex matching of the shape of the outer surface of the clamping opening assembly and the shape of the inner surface of the clamping opening sleeve.

[0014] Furthermore, the outer surface shape of the clamp assembly and the inner surface shape of the clamp sleeve work together through concave-convex cooperation.

[0015] Furthermore, sealing rings are provided around the air outlet and the air inlet of the gas transmission joint.

[0016] Furthermore, a recoil spring is provided between the gas transmission joint and the joint seat.

[0017] Furthermore, a reset spring is provided between the clamp assembly mounting sleeve and the connector seat.

[0018] The beneficial effects of the present invention are as follows: since a clamping assembly that can be opened and closed freely is provided around the outlet of the air duct, when the joint is connected to the workpiece to be measured, the clamping assembly closes and clamps the air inlet of the workpiece to be measured to prevent the joint from falling off, and the movable clamping sleeve controls the opening and closing of the clamping assembly. When the joint is separated from the workpiece to be measured, the clamping sleeve slides backward, and the clamping assembly is separated by the concave-convex matching of the outer surface shape of the clamping assembly and the inner surface shape of the clamping sleeve.

[0029] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0031] The invention discloses an airway joint for vacuum melting of magnesium alloy. In the actual field of vacuum melting of magnesium alloy, the quality of the airway joint directly affects the product quality of the vacuum melting of magnesium alloy.

[0032] This application proposes an airway joint for vacuum melting of magnesium alloys, which practically solves the problems existing in traditional airway joints during magnesium alloy vacuum melting. Through structural design, a freely openable and closable clamping assembly is provided around the outlet of the airway. When the joint is connected to the workpiece to be tested, the clamping assembly closes and clamps the air inlet of the workpiece to be tested to prevent the joint from falling. Furthermore, the movable clamping sleeve controls the opening and closing of the clamping assembly. When the joint is separated from the workpiece to be tested, the clamping sleeve slides backward, and the clamping assembly is separated by the concave-convex shape of the outer surface of the clamping assembly and the inner surface of the clamping sleeve.

[0033] like Figure 1-8 As shown, the gas duct joint for vacuum melting of magnesium alloy includes a joint seat 3, an air duct 3.1 is provided inside the joint seat 3, an air duct interface 4 is provided at the inlet of the "L"-shaped air duct 3.1, and the outlet of the air duct 3.1 is connected to the gas supply joint 5, and the gas supply joint 5 matches the gas inlet and outlet of the workpiece to be measured; a first sealing ring 5.1 is provided at the outlet edge of the gas supply joint 5, and a second sealing ring 5.2 is provided at the inlet edge of the gas supply joint 5.

[0034] like Figure 4-6As shown, one end of the connector seat 3 is provided with a "recessed" head for placing the gas connector 5, and the clamp mounting sleeve 6 connects the connector seat 3 and the gas connector 5 together. The clamp mounting sleeve 6 is symmetrically provided with a clamp assembly 1 near the outlet of the gas connector 5. The outside of the clamp mounting sleeve 6 is sleeved with a clamp sleeve 2. When the clamp sleeve 2 moves to one side of the clamp assembly 1, the inner wall of the clamp sleeve 2 cooperates with the outer surface of the clamp assembly 1 to control the closing of the clamp assembly 1. When the clamp sleeve 2 moves to the opposite side of the clamp assembly 1, the inner wall of the mouth sleeve 2 cooperates with the outer surface of the clamp assembly 1 to control the opening of the clamp assembly 1.

[0035] A return spring is provided inside the clamping sleeve 2 to control the clamping sleeve 2 to automatically return to the closed state of the clamping assembly 1.

[0036] Those skilled in the art will appreciate that the embodiments described herein are intended to help readers understand the principles of the present invention, and should be understood that the scope of protection of the present invention is not limited to such specific descriptions and embodiments. Those skilled in the art can, based on the technical teachings disclosed in this utility model, make various other specific variations and combinations that do not depart from the essence of the present invention, and such variations and combinations are still within the scope of protection of the present invention.
