Embodiment 1

[0016] Such as Figure 1~2 As shown, the door of this embodiment includes a door frame 1, a door leaf and an opening and closing mechanism. The door frame 1 is at least provided with a circumferentially closed flange 2; the door leaf is hinged on the door frame 1, and the door leaf It includes a base body 3 and a heat insulating layer 4, the base body is a groove with a closed side wall, and a closed reinforcing rib 5 that is not in contact with the side wall of the groove is arranged in the groove, and the closed reinforcing rib 5 surrounds A heat insulating layer 4 is arranged in the formed space, and a sealing strip 6 corresponding to the flange 2 is arranged in the space between the closed reinforcing rib 5 and the side wall of the groove; the opening and closing mechanism includes a rotating shaft 7, Connect the flange 8, the connecting rod 9 and the guide sleeve 10. The rotating shaft 7 passes through the light hole of the door leaf and can rotate in the light hole. On t...

Embodiment 2

[0021] Such as Figure 2~3 As shown, the main difference between the present embodiment and embodiment 1 is: a window 14 is installed on the door leaf. Window 14 main bodies adopt explosion-proof glass, and do necessary sealing. The purpose of installing the viewing window is to provide convenience for observing changes in the environment outside the door from inside the door.

[0022] The working principle of the present invention is: when it is necessary to enter the door, just turn the hand wheel outside the door, that is, turn the shaft, and the connecting flange threaded with the shaft will perform a spiral motion, thereby driving the connecting rod to shrink along the guide sleeve, When the connecting rod leaves the door frame, pull the hand wheel outward, and the door leaf will turn outward around the hinged shaft of the door frame, thereby opening the door; when locking the door, just turn the hand wheel in the opposite direction.

[0023] The invention is mainly use...

Abstract

The invention discloses a door, which comprises a door frame, a door leaf and an opening and closing mechanism, wherein the door leaf is hinged on the door frame, and a secondary sealing structure is adopted between the door leaf and the door frame; the door leaf comprises a basal body and a heat insulation layer; the opening and closing mechanism comprises a rotating shaft, a connecting flange, a connecting rod and a guide sleeve; the rotating shaft passes through a light hole penetrating the door leaf and can rotate in the light hole; on the inner side of the door leaf, the rotating shaft is in threaded connection with the connecting flange; the connecting rod is hinged on the connecting flange; and the connecting rod passes through the guide sleeve arranged on the door leaf. The door is mainly used as a capsule door of a rescue capsule for mine to solve the problems of complex structure and poor sealing and heat insulation effects of the capsule door opening and closing mechanism of the conventional rescue capsule for mine, can also be used as a door of a cabin, a cold store or the like, and has the advantages of simple structure of the opening and closing mechanism and good sealing and heat insulation effects.

Description

technical field [0001] The present invention relates to a door. Background technique [0002] There are many kinds of existing doors, and the structures are also different according to different application occasions. At present, the hatches of the rescue cabins used in mines generally have the problems of complex structure of the opening and closing mechanism, and poor sealing and heat insulation effects. Contents of the invention [0003] The object of the present invention is to provide a door to solve the problems of complex structure, poor sealing and heat insulation effect of the door opening and closing mechanism of the existing mine rescue cabin. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] A door, comprising a door frame, a door leaf and an opening and closing mechanism, the door frame is provided with at least a circumferentially closed flange; the door leaf is hinged on the door frame, the door l...
