Description

Technical Field

[0001] The utility model relates to the technical field of cold-proof doors, in particular to a new type of cold-proof door. Background Art

[0002] A winter door is a door specifically designed to block cold weather from entering a home, thereby increasing the warmth of the living or working space.

[0003] Now we are looking for a new type of cold-proof and heat-insulating door and window with a Chinese patent, publication number CN 214273314 U, which includes a door leaf and a door frame. The door leaf has a rotating shaft at the bottom, and a bearing is installed on the door frame. Under the action of the rotating shaft and bearing, the door leaf can be rotatably connected to the inner side of the door frame; the door leaf and door frame both include a thermal break bridge and several cavities, and the cavities are symmetrically distributed on both sides of the thermal break bridge; the door leaf and door frame of this new type of cold-proof and heat-insulating door and window have cavities and thermal break bridge structures, and the thermal break bridge is filled with polyurethane foam. The cavity and thermal break bridge can effectively isolate the external temperature and noise, and the structure is more solid and reliable; the combination of the rotating shaft and bearing can reduce the friction between the door leaf and door frame, and increase the service life of the door and window. A sealing strip is installed on the connecting surface of the door leaf and door frame to effectively isolate dust and make the connection tight.

[0004] Existing cold-proof doors have sealing strips installed between the two doors of the double-leaf door to ensure the thermal insulation effect at the door gap after the door is closed. However, this sealing strip is usually clamped on the side of the door leaf. After long-term use, the sealing strip needs to be replaced to ensure its sealing. This clamping method makes it time-consuming and labor-intensive to replace the sealing strip. Therefore, a new cold-proof door is needed to solve the above problem. Utility Model Content

[0005] The purpose of the present utility model is to provide a new cold-proof door to solve the problem raised in the above-mentioned background technology that the sealing strip is usually clamped on the side of the door leaf.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a new cold-proof door, comprising:

[0008] The door body assembly includes a door leaf, a groove and a sealing strip, wherein the groove is provided on the outer side of the door leaf and the sealing strip is inserted into the groove;

[0009] A connecting component includes an opening, a support plate, a connecting column and a first through hole. The opening is opened at the lower end of the groove, the support plate fits in the opening, the connecting column is fixed to the side of the support plate, the first through hole is opened on the side of one end of the sealing strip, and the connecting column is inserted into the first through hole.

[0010] Furthermore, the connecting assembly further comprises a pull plate and a second through hole, the pull plate is hinged to the top end of the support plate, and the second through hole is opened in the middle of the pull plate.

[0011] Furthermore, the support plate is movably connected in the groove, and the pull plate is movably connected in the groove and at the upper end of the groove.

[0012] Furthermore, the door body assembly also includes insulating glass, and the insulating glass is adhered to the inner side of the door leaf by glass glue.

[0013] Furthermore, it also includes a positioning component, which includes a U-shaped fixing plate and a slot. The U-shaped fixing plate is fixed at the lower end of the opening, and the slot is opened in the middle of the side of the U-shaped fixing plate.

[0015] Compared with the prior art, the advantages of the present invention are:

[0016] 1. The utility model provides a connection assembly. When a new sealing strip needs to be replaced, the sealing strip is buckled out from the opening below the groove, and then the sealing strip is pulled to pull out the old sealing strip. At this time, the support plate falls from the upper end of the groove to the opening, and the first through hole of the new sealing strip is stuck on the connecting column of the support plate. The second through hole of the pull plate is pulled along the groove to move the support plate to the upper end of the groove. The upper end of the new sealing strip moves to the upper end of the groove along with the support plate, and the sealing strip is stuck in the groove. Then the pull plate is rotated 90 degrees to fit the upper end of the groove. This arrangement can quickly disassemble and assemble the sealing strip, saving replacement time.

[0017] 2. The utility model provides a positioning component. When a new sealing strip is installed in the groove, the lower end of the sealing strip is pulled up to bend it and then inserted into the U-shaped fixing plate. The middle position of the lower end of the sealing strip is stuck in the groove. This setting can fix the lower end of the sealing strip to prevent shaking from affecting the sealing effect.
