As shown in fig. 1 to 6, the vacuum joint of the present invention includes a joint base 100, a joint body 200, and a gas amount adjusting valve 300; a cavity is arranged in the joint seat 100, and a first through hole 101 communicated with the cavity is formed in the joint seat 100; the joint body 200 comprises a vacuum air duct 201 and a second through hole 202, one end of the joint body 200 extends into the chamber, and the second through hole 202 is formed in one end of the joint body 200 extending into the chamber; one end of the vacuum air channel 201 is connected with an external vacuum source, and the other end of the vacuum air channel is communicated with the second through hole 202 so that the chamber is communicated with the vacuum source; the air amount adjusting valve 300 is installed on the coupling body 200 to be able to adjust the amount of air passing through the vacuum duct 201.
The utility model discloses in, the vacuum source communicates with first through-hole 101 through the vacuum air flue that connects body 200 and the cavity of adapter 100, because air quantity regulating valve 300 is installed on connecting body 200, consequently can realize the function of adjusting the tolerance through vacuum air flue 201 through air quantity regulating valve 300. Therefore, the utility model discloses a vacuum joint has the advantage that can conveniently adjust the tolerance of evacuation.
In order to facilitate the opening and closing operations of the vacuum coupling, optionally, the vacuum coupling includes a moving block 400, and the moving block 400 is movably disposed in the chamber in a first direction; wherein the moving block 400 is configured to be movable in a first direction between a blocking position in which the moving block 400 is able to disconnect the first through hole 101 from the chamber, and a conducting position in which the moving block 400 allows the first through hole 101 to communicate with the chamber. In the above embodiment, the external vacuum source communicates with the first through hole 101 through the socket 100 and the socket body 200. The moving block 400 realizes the function of turning on and off the vacuum source and the first through hole 101, specifically: when the moving block 400 moves to the shielding position in the first direction, the moving block 400 disconnects the first through hole 101 from the chamber, and when the moving block 400 moves to the conducting position in the first direction, the moving block 400 conducts the first through hole 101 to the chamber. The utility model discloses a vacuum joint simple structure only can realize opening and closing the function of vacuum joint through the removal of movable block 400, and is easy and simple to handle, high-efficient, has effectively solved current vacuum joint and has had complex operation's problem.
In order to ensure the stability of the closed state of the vacuum connector, that is, the problem of vacuum leakage does not occur in the vacuum connector, it is necessary to precisely move the moving block 400 to the shielding position, and optionally, the moving block 400 is provided with a first tapered surface 401, and the chamber is provided with a second tapered surface 102 engaged with the first tapered surface 401 to guide the moving block 400 to move from the conducting position to the shielding position.

Another benefit of the interaction through two conical surfaces to achieve the guiding is that, because the moving block 400 moves in the chamber, the cooperation of the two conical surfaces can limit six degrees of freedom thereof, so that the moving block 400 can move accurately, and if a guide structure in the form of a guide rail or the like is adopted, only two degrees of freedom of the moving block 400 can be limited, and if the vacuum joint vibrates, it cannot be guaranteed that the moving block 400 can move accurately to a shielding position.
In order to ensure that the moving block 400 in the shielding position can effectively achieve the function of disconnecting the first through hole 101 from the vacuum source, optionally, the vacuum joint includes a first sealing ring 501 and a second sealing ring 502 capable of achieving sealing between the first tapered surface 401 and the second tapered surface 102, and the first sealing ring 501 and the second sealing ring 502 have a first distance therebetween along the first direction, and the first distance is configured such that the moving member in the shielding position can enable the first through hole 101 to be located between the first sealing ring 501 and the second sealing ring 502. In other words, the arrangement positions of the first sealing ring 501 and the second sealing ring 502 can ensure that when the moving block 400 moves to the shielding position, the first through hole 101 is just located between the first sealing ring 501 and the second sealing ring 502, and because the first sealing ring 501 and the second sealing ring 502 realize sealing between the moving block 400 and the inner wall of the chamber, the first through hole 101 is disconnected from the chamber in the direction of the first sealing ring 501 or the direction of the second sealing ring 502, so that the moving block 400 can effectively realize the function of disconnecting the first through hole 101 from the vacuum source.
It should be appreciated that the moving block 400 can be moved between the blocking position and the conducting position in a variety of ways, for example, the moving block 400 can include a moving structure to drive the moving block 400 to move between the blocking position and the conducting position, in one embodiment of the present invention, the joint body 200 can be optionally configured to move in a first direction to drive the moving block 400 to move between the blocking position and the conducting position.
