Description

Technical Field

[0001] The utility model relates to the technical field of thermal insulation doors, in particular to a flat-opening sealed thermal insulation door for a granary. Background Art

[0002] As we all know, a granary is a special building for storing grain, which is used to store a large amount of grain. The entrance and exit of the granary are generally equipped with an insulated door to protect the grain inside. The existing insulated door is generally composed of a door frame and a door leaf. The door leaf of the swing-open sealed insulated door is generally connected to the door frame through a hinge. The interior of the door leaf is provided with a polystyrene flame-retardant foam board which has good thermal insulation properties. The door frame is provided with bosses and rubber pads that are against the door leaf to improve the sealing between the door leaf and the door frame. However, the setting of the boss below affects the flatness of the door frame. When pushing the equipment through the door frame, it is often necessary to lift the equipment over the boss before moving it, which affects the convenience of use. Utility Model Content

[0008] Furthermore, the lower sealing unit also includes a spring sheet, which is symmetrically arranged inside the rectangular hole of the bottom wall of the door frame, and the upper end of the spring sheet is matched with the upper side wall of the sealing shell to provide an upward force to the sealing shell.

[0009] Furthermore, the lower sealing unit also includes a connecting strip and a C-shaped sleeve. The connecting strip is respectively arranged at the left and right ends of the front side of the sealing shell. The C-shaped sleeve is respectively slidably connected to the left and right sides of the lower end of the door frame. The front end of the connecting strip is fixedly connected to the laterally adjacent C-shaped sleeve to facilitate the control of the sealing shell.

[0010] Furthermore, a baffle frame is provided at the rear end inside the door frame, a rubber pad is provided on the front side of the baffle frame, and the rear iron sheet layer is arranged in cooperation with the rubber pad to improve the sealing performance of the door leaf around the periphery.

[0013] Compared with the prior art, the utility model has the following beneficial effects: the granary flat-opening sealed thermal insulation door has the following advantages:

[0014] When the door leaf frame opens and rotates, the door leaf frame squeezes the C-type sleeve along the chamfer at the rear end of the C-type sleeve, and then the C-type sleeve slides downward along the slide groove of the door frame. The C-type sleeve drives the sealing shell to slide downward along the rectangular block through the connecting strip and squeezes the spring sheet, and then the sealing shell will shrink to the inside of the door frame to form a plane, thereby facilitating the passage of vehicles and equipment. When the door leaf frame is closed, the door leaf frame is separated from the C-type sleeve, and then the spring sheet provides an upward force to the sealing shell. The sealing shell can be in close contact with the rubber pad to ensure good sealing between the door leaf and the door frame. A lifting sealing shell is provided at the lower end of the door frame to ensure good sealing effect at the lower end between the door frame and the door leaf. At the same time, as the door leaf opens, the sealing shell can be automatically pressed down to form a flat plane, thereby facilitating the passage of equipment. BRIEF DESCRIPTION OF THE DRAWINGS
