Detailed Description

As shown in fig. 1, a sealing door includes a door cover 1100, a door frame 1200, and a locking mechanism 1300.

As shown in fig. 1 to 3, the door cover 1100 is hinged to the door frame 1200, and the door frame 1200 is located at the rear side of the door cover 1100, and a gasket 1400 is disposed between the door cover and the door frame 1200.

Locking mechanism 1300 includes a lock pad 1310, a hinge base 1320, a lock handle 1330, and a connecting rod 1340.

The locking pad 1310 is fixed to a side of the door cover 1100, and the hinge base 1320 is located at a rear side of the locking pad 1310 and fixed to a side of the door frame 1200. Here, the fixing can be performed, for example, by welding or other known fixing connection means.

One end of the locking handle 1330 forms an eccentric 1331 that rotates horizontally along a vertical eccentric shaft 1332, the eccentric 1331 being located at the front side of the locking pad 1310.

One end of the connecting rod 1340 is horizontally and rotatably connected to the eccentric shaft 1332, and the other end thereof passes through the locking pad 1310 and is horizontally and rotatably connected to the hinge base 1320.

The utility model discloses utilize eccentric wheel 1331's characteristic, make eccentric shaft 1332 and the distance between the locking pad 1310 change through rotatory locking handle 1330 to accomplish locking and the release between door frame and the door closure. Specifically, taking the locking mechanism 1300 on the left side in fig. 1 as an example (in which the handle is rotated clockwise by half), by rotating the locking handle 1330 clockwise, the distance between the eccentric shaft 1332 and the locking pad 1310 is increased (i.e., the locking handle 1330 is rotated from the small diameter surface to the large diameter surface to contact with the locking pad 1310), so as to lock the door frame and the door cover (at this time, the locking handle 1330 is parallel to the left side of the door frame); by rotating the locking handle 1330 counterclockwise, the distance between the eccentric shaft 1332 and the locking pad 1310 is reduced (i.e., the eccentric shaft is rotated to the small diameter surface from the large diameter surface to be contacted with the locking pad 1310) to release the locking state between the door frame and the door cover, thereby realizing the rapid locking and releasing between the door cover of the sealing door and the door frame, and the operation is convenient and the efficiency is improved.

In this embodiment, the rear surface of the door 1100 is provided with a gasket fixing groove, and the gasket 1400 is fixed in the fixing groove. Specifically, the gasket 1400 is a rubber gasket.

As shown in fig. 2, the door cover 1100 has a handle 1110 on the front surface.

Preferably, as shown in fig. 1, the door cover 1100 is hinged to the door frame 1200 at the left side by upper and lower hinges 1500. The number of the locking mechanisms 1300 is three, two of the locking mechanisms 1300 are arranged on the right side at intervals up and down, and one locking mechanism 1300 is arranged between the two hinges 1500 on the left side.

In this embodiment, as shown in FIG. 1, the front side of the locking pad 1310 has an arcuate slot that fits over the cam 1331 to facilitate rotation of the cam 1331.

In the present embodiment, as shown in fig. 1 and 3, the eccentric wheel 1331 is formed of two disks 1331a spaced up and down, the eccentric shaft 1332 passes through the two disks 1331a up and down and is rotatably connected to the two disks 1331a, and one end of the connecting rod 1340 is horizontally rotatably connected to the eccentric shaft 1332 between the two disks 1331 a.

However, those skilled in the art should realize that the above embodiments are only used for illustrating the present invention and not used as a limitation of the present invention, and that the changes and modifications to the above embodiments are within the scope of the appended claims as long as they are within the true spirit of the present invention.
