Embodiment one

Refer to shown in Fig. 1, Fig. 3, Fig. 4, Fig. 6, Fig. 1 and Fig. 3 be respectively the present embodiment provide in preceding door closure state Stereogram, the side view of lower vacuum drying chamber, Fig. 4 and Fig. 6 are respectively the present embodiment offer under the full open position of front door Stereogram, the side view of vacuum drying chamber.

With reference to shown in Fig. 1, Fig. 3, Fig. 4, Fig. 6, a kind of air-actuated turnover door 2 is present embodiments provided, it includes：Door body 21, Pneumatic turnover mechanism located at the door body left and right sides.

Pneumatic turnover mechanism includes：Rotating seat 22, the first cylinder 23, the second cylinder 24；Rotating seat 22 further comprises：Rotation Swivel base body, the rotating part on rotating seat body, and it is divided into the first connecting portion and second at rotating seat body two ends Connecting portion.

The telescopic rod end of first cylinder 23 is fixedly connected and is mutually perpendicular with the side of door body 21, cylinder body is fixed on In the first connecting portion of rotating seat 22；The telescopic rod end of second cylinder 24 rotatably connects with the second connecting portion of rotating seat 22 Connect.

It is by the method that is installed on casing of above-mentioned air-actuated turnover door：Rotating seat 22 is rotatably installed by its rotating part In on the left/right side outer wall of casing so that rotating seat 22 can be using rotating part as axle center, relative to the left/right of casing in stress Side outer wall is rotated clockwise or counter-clockwise；Meanwhile, the cylinder base of the second cylinder 24 is fixed on by a fixed seat On casing, and make it that the axial direction of the second cylinder 24 is parallel with the left/right side outer wall of casing.

Wherein, the expansion link of the first cylinder 23 does straight line back and forth movement, for driving door body 21 vertical with its plane Straight line back and forth movement is done on direction.The expansion link of second cylinder 24 does straight line back and forth movement, for drive rotating seat 22 relative to The left/right side outer wall of casing is rotated, while to drive the first cylinder 23 and door body 21 to carry out clockwise or inverse for rotating seat 22 Hour hands rotate.

When original state is closed mode (as shown in Figure 3), the opening process of air-actuated turnover door is：

1) straight forward movement of door body 21 is promoted by the expansion link of the first cylinder 23, until door body 21 and the front side of casing Opening is at a distance of pre-determined distance A；

2) rotate counterclockwise of rotating seat 22, first be fixed on rotating seat 22 are promoted by the expansion link of the second cylinder 24 Cylinder 23 and door body 21 are with the rotate counterclockwise of rotating seat 22, until door body 21 is parallel with the top surface of casing；

3) door body 21 is pulled to move along a straight line downwards by the expansion link of the first cylinder 23, until door body 21 is close to the top of casing Face, as shown in Figure 6.

When original state is opening (as shown in Figure 6), the closing process of air-actuated turnover door is：

1) door body 21 is promoted to move along a straight line upwards by the expansion link of the first cylinder 23, until door body 21 and the top surface of casing At a distance of pre-determined distance A；

2) rotating seat 22 is pulled to turn clockwise by the expansion link of the second cylinder 24, first be fixed on rotating seat 22 Cylinder 23 turns clockwise with door body 21 with rotating seat 22, until door body 21 is plumbness, parallel to the front openings of casing；

3) door body 21 is pulled to move along a straight line backward by the expansion link of the first cylinder 23, until before the closed box of door body 21 Side opening, as shown in Figure 3.

Pre-determined distance A setting is unrestricted, it is only necessary to meet following condition：In the rotary course of door body 21, door There is gap between body 21 and casing, in case door body 21 touches that to cause it to be turned on or off not smooth because being wiped with casing.

To sum up, air-actuated turnover door is located at the top surface of casing, any work not accounted in front of casing after unlatching in the present embodiment Make space, greatly save space-consuming, thus will not to battery core picking and placeing and other adjacent casings produce interference, and The upset of door body is driven by two cylinder interactions, implementation is simple and quick.

Embodiment two

In embodiment one, the anglec of rotation of door body 2 is controlled by the second cylinder 24, it is not in place that it rotation easily occurs Or the problem of rotate excessive so that descend in off position not parallel between door body 2 and casing, it is impossible to completely enclosed to export.

Thus, in the present embodiment two, the anglec of rotation is controlled for convenience, in case door body 21 rotates not in place or rotation Excessively, the position-limit mechanism 26 in the position limiting structure 25 and Fig. 4 in two position-limit mechanisms, such as Fig. 1 is additionally arranged on casing.

Wherein, position-limit mechanism 25, position-limit mechanism 26 are divided into the both sides of rotating seat 22, so as to the anglec of rotation of rotating seat 22 Degree progress is spacing, and in the present embodiment, the anglec of rotation of rotating seat 22 is defined into 90 degree.

Embodiment three

The present embodiment proposes a kind of vacuum drying chamber of the above-mentioned air-actuated turnover door of application.
