Embodiment 1

[0016] like Figures 1 to 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 provided with at least a circumferentially closed flange 2; the door leaf is hinged on the door frame 1, and the door leaf is It includes a base body 3 and a heat insulation 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 provided in the groove, and the closed reinforcing rib 5 surrounds the groove. 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, Connecting flange 8, connecting rod 9 and guide sleeve 10, the rotating shaft 7 passes through the light hole through the door leaf and can be rotated in the ...

Embodiment 2

[0021] like Figures 2 to 3 As shown, the main difference between this embodiment and Embodiment 1 is that a window 14 is installed on the door leaf. The main body of the window 14 is made of explosion-proof glass and must be sealed. The purpose of installing the viewing window is to facilitate the observation of changes in the environment outside the door from inside the door.

[0022] The working principle of the invention is as follows: when it is necessary to enter the door, only the hand wheel outside the door needs to be rotated, that is, the rotating shaft is rotated, and the connecting flange threadedly connected with the rotating 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, the door leaf will rotate outward around the hinge shaft with the door frame, so as to open the door; when the door is locked, just turn the hand wheel in the opp...

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 structure is different according to the application. At present, the hatch doors of the rescue cabins used in mines generally have the problems of complex opening and closing mechanisms, poor sealing and thermal insulation effects. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a door to solve the problems of the complex structure of the hatch door opening and closing mechanism of the existing mine rescue cabin, and the poor sealing and thermal insulation effects. [0004] The purpose of this invention is to realize 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 leaf includes a base...
