AI Technical Summary
Existing thermally broken windows and doors have poor insulation performance, causing outdoor heat to transfer into the room and affecting indoor comfort.
A novel thermally broken door has been designed, comprising a door frame, door panel, locking structure, door hinge, door flap, dustproof strip, and shock-absorbing sealing strip. The door frame is equipped with a blocking groove and a heat-insulating groove. The surface of the shock-absorbing sealing strip has a corrugated raised surface, and the blocking groove has a locking groove. The door panel is connected to the door flap through the door hinge. After the door panel rotates to the blocking groove and enters the heat-insulating groove, the dustproof strip and the shock-absorbing sealing strip deform and squeeze the contact surface until they lock into the locking groove, thus achieving a seal. The door is equipped with a heat-insulating cavity to enhance the heat insulation effect.
By improving the structure, the door's sealing and heat insulation effects were enhanced, preventing a decline in heat insulation performance and ensuring the heat insulation performance of the thermally broken door.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of thermal break doors, and in particular to a novel thermal break door. Background Technology
[0002] As is well known, the principle of thermally broken aluminum alloy windows is to use PA66 nylon to separate and tightly connect the indoor and outdoor aluminum alloys into a whole, forming a new type of thermally insulated aluminum profile. Depending on the connection method, it can be divided into strip-type and glue-injection type.
[0003] However, the existing thermal break windows and doors have poor heat insulation performance. When the sun is strong, outdoor heat will still be transferred into the room, which will raise the indoor temperature and affect the comfort of consumers indoors. Summary of the Invention
[0004] The purpose of this utility model is to address the aforementioned problems by providing a new type of thermally insulated door.
[0005] To address the aforementioned problems, a novel thermally broken door is provided, characterized by comprising a door frame, a door panel, a locking structure, a door hinge, door hinge A, door hinge B, a dustproof strip, and a shock-absorbing sealing strip. The door frame contains a blocking groove and an insulation groove. A shock-absorbing sealing strip is located on the side of the insulation groove near the blocking groove, and the surface of the shock-absorbing sealing strip has corrugated protrusions. A locking groove is provided within the blocking groove. Door hinge A is bolted to the side of the door frame near the insulation groove, and door hinge B is bolted to the side of the door panel. A door hinge is located between door hinge A and door hinge B, and the door hinge passes through door hinge A and door hinge B. The door frame cross-section is made of thermally broken aluminum material.
[0006] Preferably, a sealing block is provided on the side of the door panel away from the bolt connection end of the door hinge B. The length of the sealing block matches the length difference between the blocking groove and the insulation groove. A dustproof strip is provided on one side of the sealing block. The dustproof strip has a circular cross-section and is partially embedded in the sealing block.
[0007] Preferably, the door panel is provided with a door handle, and the door handle passes through the door panel and a locking block is provided on the side near the locking groove.
[0008] Preferably, the dustproof strip is closer to the side wall of the insulation groove than the shock-absorbing sealing strip, and both the dustproof strip and the shock-absorbing sealing strip are C-shaped.
[0009] Preferably, the door panel has a heat insulation cavity inside.
[0010] In summary, the beneficial effects of this utility model are:
[0011] This utility model modifies some of the structure. When in use, the door panel is rotated until the blocking block enters the insulation groove. Pressing the door leaf deforms and squeezes the dustproof strip and shock-absorbing sealing strip to compress the contact surface until the locking block can rotate into the locking groove. The dustproof strip and shock-absorbing sealing strip can seal the gaps between the door panel and the door frame, preventing a decrease in the heat insulation effect. The heat insulation cavity set inside the door can enhance the heat insulation effect of the door panel, thereby ensuring the heat insulation effect of the thermally broken door.
