DETAILED DESCRIPTION

[0029] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0030] The utility model provides a sealing device for a pressure steam sterilizer, comprising:

[0031] Pressure steam sterilizer body 1;

[0032] A sealing cover 2 is disposed above the pressure steam sterilizer body 1 and is used to seal the pressure steam sterilizer body 1;

[0033] The first fixing blocks 3, which are in two pairs, are fixedly mounted on the outer surface of the pressure steam sterilizer body 1;

[0034] The second fixing blocks 4, which are in two pairs, are fixedly mounted on the outer surface of the pressure steam sterilizer body 1 and are respectively located below the two pairs of first fixing blocks 3;

[0035] A threaded rod 5, one end of which is rotatably connected to one end surface of the first fixing block 3, and the other end of which passes through the second fixing block 4;

[0036] A square moving block 6 is threadedly connected to the threaded rod 5, and one end surface of the square moving block 6 is in contact with the outer surface of the pressure steam sterilizer body 1;

[0037] There are two pairs of connecting blocks 7, both of which are fixedly mounted on the outer wall surface of the sealing cover 2;

[0038] A plug hole 8 is formed in the connecting block 7;

[0039] A connecting rod 9, one end of which is hinged to one end surface of the square moving block 6, and the other end of which is plugged into the plug hole 8;

[0040] A driving assembly, disposed on the outer surface of the pressure steam sterilizer body 1, and used to drive the threaded rod 5 to rotate;

[0041] Under the action of the driving assembly, the two pairs of threaded rods 5 can rotate at the same time, and the rotation of the threaded rods 5 can drive the square moving block 6 to move at the same time, and the movement of the square moving block 6 can drive the connecting rod 7 to move at the same time. At this time, one end of the connecting rod 7 is plugged into the plug hole 8, and the movement of the square moving block 6 can drive the connecting rod 9 to apply a downward pulling force to the connecting block 7, so that the sealing cover 2 can more stably seal the pressure steam sterilizer body 1.

[0042] Specifically, the drive components include;

[0043] The gear 10 is fixedly connected to one end of the threaded rod 5 passing through the second fixing block 4;

[0044] The rotation of the gear 10 can drive the threaded rod 5 to rotate at the same time, so that the square moving block 6 moves on the threaded rod 5;

[0045] An annular slide groove 11 is formed on the outer surface of the pressure steam sterilizer body 1;

[0046] The annular slide block 12 is slidably mounted in the annular slide groove 11;

[0047] The annular member 13 is disposed on the outer side of the annular slider 12 and is fixedly connected to the annular slider 12;

[0048] The inner gear ring 14 is fixedly mounted on the inner surface of the ring member 13 and meshedly connected with the gear 10;

[0049] The rotation of the annular member 13 can drive the annular slider 12 to slide in the annular slot 11, so that the annular member 13 remains stable when rotating. At the same time, the rotation of the annular member 13 can drive the inner gear ring 14 to rotate at the same time, and the rotation of the inner gear ring 14 can drive the gear 10 to rotate at the same time.

[0050] Specifically, two pairs of positioning grooves 15 are formed on the lower end surface of the sealing cover 2, and a positioning rod 16 plugged into the positioning grooves 15 is fixedly installed on the upper end surface of the pressure steam sterilizer body 1;

[0051] Under the action of the positioning groove 15 and the positioning rod 16 , the sealing position of the sealing cover 2 on the pressure steam sterilizer body 1 can be positioned, so that one end of the connecting rod 7 can be plugged into the plug hole 8 in the connecting block 7 .

[0052] Specifically, a sealing ring 17 is provided on the lower end surface of the sealing cover 2;

[0053] The sealing ring 17 is bonded to the lower end surface of the sealing cover 2, and its lower end surface contacts the upper end surface of the pressure steam sterilizer body 1, which can improve the sealing performance and facilitate replacement of the sealing ring 17 when it is aged after long-term use.

[0054] Specifically, one end of the plug-in hole 8 is an inclined surface, which can facilitate the plugging of one end of the connecting rod 9 with the plug-in hole 8.

[0055] Working principle: When the pressure steam sterilizer body 1 needs to be sealed, the staff first places the sealing cover 2 on the upper end of the pressure steam sterilizer body 1, and at the same time inserts the positioning rod 16 into the positioning groove 15 to position the sealing cover 2, and at the same time flips the connecting rod 9 to make it in a vertical state. At this time, the staff rotates the annular member 13, and the rotation of the annular member 13 can drive the annular slider 12 to slide in the annular slide groove 11, so that the annular member 13 remains stable when rotating. At the same time, the rotation of the annular member 13 can drive the inner gear ring 14 to rotate at the same time. At this time, the rotation of the inner gear ring 14 can drive the gear 10 and the threaded rod 5 to rotate at the same time. The rotation of the threaded rod 5 can drive the square moving block 6 and the connecting rod 9 to move downward at the same time. At this time, one end of the connecting rod 9 is inserted into the plug hole 8, and at the same time, the square moving block 6 moves, which can make the connecting rod 9 apply a downward pulling force to the connecting block 7, so that the sealing cover 2 seals the pressure steam sterilizer body 1. At the same time, the sealing cover 2 and the pressure steam sterilizer body 1 can clamp the sealing ring 17, which can improve the sealing effect and bring convenience to people.
