Therefore, a square manual sealing cabin is proposed. Utility Model Content

[0003] In view of the above existing technical problems, the utility model provides a square manual sealed cabin, which is characterized by comprising a box body, a box door, a handle, a convex block, a limit block, a hinge, a spring, and a sealing gasket. The box body is provided with a box door in front, a handle is provided on the surface of the box door, a convex block is provided at the front end of the handle, a hinge is provided on the surface of the box door, a spring is provided in the hinge, a sealing gasket is provided in the box door, and a limit block is provided on the box body;

[0004] Furthermore, the handle is fixedly connected to the protrusion, the handle is fixedly connected to the box door, and the protrusion is in close contact with the limit block;

[0005] Furthermore, one end of the hinge is fixedly arranged on the box door, and the other end is fixedly connected to the box body, and the spring is located inside one end close to the box body;

[0006] Furthermore, the sealing gasket is located between the box body and the box door.

[0007] Beneficial effects of the utility model:

[0008] The utility model pulls the handle outward, and the handle drives the convex block to rotate slightly clockwise, so that the convex block is separated from the limit block, and the box door is opened by the hinge. At this time, the spring is compressed; when closing, the box door is pushed, and the convex block enters the limit block under the action of external force and is stuck by the limit block. At this time, the spring is stretched and has a rebound effect, so that the box door with the sealing gasket 5 is well pressed on the box body, thereby obtaining an ideal sealing effect.
