The driven pressing unit comprises a driven inserting plate 61 and a driven pressing stop block 63 which are arranged at the top of the sealing cover 2 through a driven sliding block guide rail 62, the driven inserting plate 61 is connected with the driven sliding block guide rail 62 in a sliding mode, the lower portion of the driven pressing stop block 63 is connected with the outer wall of the box body 1, and a square groove is formed in the upper portion of the driven pressing stop block 63; one end of the driven inserting plate 61, which is far away from the driven pressing stop block 63, is connected with the driving inserting plate 51 through a connecting rod 64; the connecting rod 64 is rotatably connected with the driving flashboard 51 and the driven flashboard 61 through a rotating shaft 65; the axis of the driven inserting plate 61 is perpendicular to the plane of the side wall of the box body 1 where the driven pressing stop 63 is located, and passes through the center of the square groove of the driven pressing stop 63.

Example 2

Based on embodiment 1, in order to ensure that excessive operation is avoided when the manipulator is clamped, the moving position is effectively limited, two sets of center limiting blocks 4 are arranged at the symmetrical centers of the pressing mechanisms, and the center limiting blocks 4 are fixedly connected with the tops of the sealing covers 2.

Example 3

Based on embodiment 1, the top of the operation block 54 is provided with a notch 55 for stable clamping of the manipulator. The notch 55 can allow the manipulator to be clamped in, so that the stability during operation is ensured, and the phenomenon that the manipulator possibly slips from the operation block 54 in the clamping operation process is avoided.

Example 4

Based on the embodiment 1, in order to facilitate the insertion of the active/passive inserting plate into the square groove of the active/passive pressing stop block, a wedge-shaped protrusion is formed at one end of the active/passive inserting plate close to the active/passive pressing stop block.

Example 5

Example 6

Based on embodiment 1, in order to facilitate the installation of the driving pressing stopper 53 and the driven pressing stopper 63 and ensure the good sealing performance of the sealing box, a convex edge 11 is formed at the upper part of the box body 1, and the driving pressing stopper 53 and the driven pressing stopper 63 are both fixed on the convex edge 11.

Example 7

When the size of the box body is larger, the full compression can be realized by adopting a mode of widening the inserting plate and the compressing stop block.

When sealing or operation and manufacture are inconvenient, the number of the active pressing units or the driven pressing units can be increased according to the length or width requirement of the box body in a simple manner of widening the inserting plate and pressing the stop block.

When the number of the driven pressing units is increased, a pair-by-pair symmetrical increasing mode is adopted, and each pair of driven pressing units are arranged in parallel. When the number of the driven pressing units and the number of the driving pressing units are both multiple, the driven inserting plate of the driven pressing unit is connected with the driving inserting plate closest to the driven inserting plate through the connecting rod.

When the number of the active pressing units is increased, the active pressing units are arranged in parallel. In addition, in order to facilitate the operation of the manipulator, the connection relationship is established among all the operation blocks on the same side, so that the synchronous action of the other active pressing units can be realized when the manipulator operates one of the operation blocks.

Working principle of the invention (taking example 1 as an example):

when two symmetrical operation blocks are opened, each inserting plate extends outwards along the direction of the sliding block guide rail of each inserting plate, and along with the increase of the distance between the corresponding pressing stop block square groove of the wedge-shaped bulge at the end part of the inserting plate extending into the box body, the clearance between the sealing cover and the box body is gradually reduced, the sealing ring is extruded, and the sealing of the sealing box is realized. When two symmetrical operation blocks are fastened, each inserting plate is synchronously retracted, and the square groove of the pressing stop block on the box body is withdrawn, so that the sealing cover is opened.

Working process of the invention (taking example 1 as an example):

the cover opening process of the sealing cover:

only the operation blocks of the two active pressing units need to be clamped, so that the two active inserting plates are close to the central limiting block along the active sliding block guide rail until the two active inserting plates contact with the central limiting block, and the cover opening can be completed. In the moving process, the driving plugboards drive the driven plugboards connected with the driving plugboards to contract inwards along the guide rails of the respective driven sliding blocks through the connecting rods, so that all four driven plugboards and two driving plugboards synchronously withdraw from the corresponding driven pressing stop blocks or the driving pressing stop blocks, and the sealing cover is opened.

The sealing cover closing process comprises the following steps:

close the lid process for the reverse process of the process of uncapping, only need open the operation piece that initiatively compresses tightly the unit, make initiative picture peg remove to keeping away from central stopper direction along initiative slider guide rail, can accomplish and close the lid, remove the in-process, the initiative picture peg passes through the connecting rod and drives the driven picture peg rather than being connected and outwards expand along separately driven slider guide rail, stretch into the square groove of the initiative or the driven tight dog that corresponds through the inclined plane on initiative picture peg or the driven picture peg, realize compressing tightly the sealing washer, thereby realize closing the lid and seal.
