[0021] The following describes the specific embodiments of the present invention in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0022] like Figures 1 to 6 As shown, the vacuum joint of the present invention includes a joint seat 100, a joint body 200 and a moving block 300; the joint seat 100 has a chamber inside, and a first through hole 101 connected to the chamber is opened on the joint seat 100; one end of the joint body 200 is connected to an external vacuum source, and the other end extends into the chamber to connect the chamber with the vacuum source; the moving block 300 is movably arranged in the chamber along a first direction; wherein, the moving block 300 is configured to be able to move between a blocking position and a conducting position along the first direction, in the blocking position, the moving block 300 can disconnect the connection between the first through hole 101 and the chamber, and in the conducting position, the moving block 300 allows the first through hole 101 to be connected to the chamber.

[0023] In the present invention, since there is a chamber inside the connector seat 100, a first through hole 101 connected to the chamber is provided on the connector seat 100, one end of the connector body 200 is connected to the external vacuum source, and the other end extends into the chamber to connect the chamber with the vacuum source, that is, the external vacuum source is connected to the first through hole 101 through the connector body 200 and the chamber of the connector seat 100. The movable block 300 realizes the function of connecting and disconnecting the vacuum source and the first through hole 101, specifically: when the movable block 300 moves along the first direction to the blocking position, the movable block 300 disconnects the connection between the first through hole 101 and the chamber, and when the movable block 300 moves along the first direction to the connecting position, the movable block 300 connects the connection between the first through hole 101 and the chamber. The vacuum connector of the present invention has a simple structure, and the opening and closing functions of the vacuum connector can be realized only by moving the movable block 300. The operation is simple and efficient, and effectively solves the problem of cumbersome operation of the existing vacuum connector.

[0024] In order to ensure the stability of the closed state of the vacuum joint, that is, the vacuum joint will not have the problem of vacuum leakage, it is necessary to enable the moving block 300 to be accurately moved to the blocking position. Therefore, in one embodiment of the present invention, optionally, the moving block 300 is provided with a first guide portion, and the chamber is provided with a second guide portion cooperating with the first guide portion to guide the moving block 300 to move from the conduction position to the blocking position.

[0025] It should be understood that the first guide portion and the second guide portion can be designed in various forms, as long as they can guide the moving block 300 to move from the conducting position to the blocking position. For example, the first guide portion can include a slider, and the second guide portion can include a guide rail that matches the slider. In order to simplify the structure of the vacuum joint as much as possible without affecting the guiding function, the first guide portion can optionally include a first conical surface 301, and the second guide portion can include a second conical surface 102 that matches the first conical surface 301. In other words, Figure 3 and Figure 5 As shown, one end of the moving block 300 forms a conical structure, which has a first conical surface 301, and the inner wall of the chamber of the joint seat 100 forms a second conical surface 102. When the first conical surface 301 moves toward the second conical surface 102, the first conical surface 301 will move toward the top of the second conical surface 102 under the action of the second conical surface 102. As long as the blocking position is set on the moving path of the first conical surface 301, it can be ensured that the moving block 300 can accurately pass through the blocking position under the action of the two conical surfaces. Another advantage of guiding through the interaction of the two conical surfaces is that since the moving block 300 moves in the chamber, the cooperation of the two conical surfaces can limit its six degrees of freedom, so that the moving block 300 can move accurately. If a guiding structure in the form of a guide rail or the like is used, it can only limit two degrees of freedom of the moving block 300. If the vacuum joint vibrates, it cannot be guaranteed that the moving block 300 can accurately move to the blocking position.

[0026] In order to ensure that the movable block 300 in the blocking position can effectively disconnect the first through hole 101 from the vacuum source, optionally, the vacuum joint includes a first sealing ring 400 and a second sealing ring 500 that can achieve sealing between the first conical surface 301 and the second conical surface 102, and there is a first spacing between the first sealing ring 400 and the second sealing ring 500 along the first direction, and the first spacing is configured so that the movable block in the blocking position can enable the first through hole 101 to be located between the first sealing ring 400 and the second sealing ring 500. In other words, the setting position of the first sealing ring 400 and the second sealing ring 500 can ensure that when the moving block 300 moves to the blocking position, the first through hole 101 is exactly located between the first sealing ring 400 and the second sealing ring 500. Since the first sealing ring 400 and the second sealing ring 500 realize sealing between the moving block 300 and the inner wall of the chamber, the first through hole 101 is disconnected from the chamber both in the direction of the first sealing ring 400 and the direction of the second sealing ring 500, so that the moving block 300 can effectively realize the function of disconnecting the first through hole 101 from the vacuum source.

[0027] It should be understood that the movable block 300 can be moved between the blocking position and the conducting position in a variety of ways. For example, the movable block 300 can include a movable structure to drive the movable block 300 to move between the blocking position and the conducting position. In one embodiment of the present invention, the connector body 200 is optionally configured to be movable along a first direction to drive the movable block 300 to move between the blocking position and the conducting position. In other words, the movable block 300 is moved by the drive of the connector body 200. This configuration can simplify the structure of the movable block 300 and increase the service life of the movable block 300 during its reciprocating movement.

[0028] It should be understood that the connector body 200 can be driven to move in a variety of ways. In one embodiment of the present invention, optionally, the vacuum connector includes a driving member 800, the driving member 800 has a piston rod 801 that can move along a first direction, and the connector body 200 is mounted on the piston rod 801.

[0029] In order to ensure that the moving block 300 can be stably and firmly maintained in the blocking position when the first through hole 101 needs to be disconnected from the vacuum source, the vacuum joint optionally includes an elastic member 700 disposed in the chamber, one end of the elastic member 700 is connected to the inner wall of the chamber, and the other end is connected to the moving block to apply a thrust toward the blocking position to the moving block; the driving member 800 is configured to be able to drive the joint body 200 to overcome the thrust and push the moving block toward the conducting position. In other words, the elastic member 700 can be configured to be in a compressed state between the moving block 300 and the inner wall of the chamber, so that when the moving block 300 is not subjected to the thrust of the joint body 200, the moving block 300 is only subjected to the thrust of the elastic member 700 and is pressed in the blocking position, thereby ensuring that the moving block 300 can be stably and firmly maintained in the blocking position.

[0030] In the above embodiment, when the connector body 200 pushes the movable block 300, it needs to overcome the thrust of the elastic member 700 and push the movable block 300 in the opposite direction of the thrust direction of the elastic member 700. If the pushing direction is set at an angle to the thrust direction of the elastic member 700, it may cause the movable block 300 to tilt. For this reason, the connector body 200 may optionally have a third conical surface 203, and the chamber may have a fourth conical surface 103 that cooperates with the third conical surface 203 to guide the connector body 200 to push the movable block 300 toward the conducting position. In other words, through the cooperation of the third conical surface 203 and the fourth conical surface 103, it is possible to ensure that the connector body 200 also moves in the first direction, that is, to push the movable block 300 to move in the opposite direction of the reasoning direction of the elastic member 700, that is, to move from the blocking position toward the conducting position.

[0031] It should be understood that the connector body 200 can be designed in a variety of forms, as long as it can provide communication between the vacuum source and the chamber. In one embodiment of the present invention, optionally, the connector body 200 includes a vacuum air channel 201 and a second through hole 202; the second through hole 202 is opened at one end of the connector body 200 extending into the chamber; one end of the vacuum air channel 201 is connected to the vacuum source, and the other end is connected to the second through hole 202; the vacuum connector includes a third sealing ring 600, which is arranged on the third conical surface 203 or the fourth conical surface 103 to form a seal between the second through hole 202 and the outside world. By providing the third sealing ring 600, it is possible to ensure that a seal is formed between the second through hole 202 of the connector body 200 and the outside world when the connector body 200 pushes the moving block 300 to the conduction position, thereby preventing vacuum leakage from occurring at the second through hole 202 of the connector body 200 when the vacuum connector is in the open state.

[0032] like Figure 6As shown, the present invention further provides a vacuum system, comprising a vacuum box 900 and the aforementioned vacuum connector, wherein the first through hole 101 of the vacuum connector is located within the vacuum box 900. Due to the use of the aforementioned vacuum connector, the vacuum system of the present invention also has the advantages of simple and efficient opening and closing operations.

[0033] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Within the technical scope of the present invention, various simple variations of the technical solution of the present invention may be made. To avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple variations and combinations should also be considered as disclosed in the present invention and fall within the scope of protection of the present invention.
