Description

Technical Field

[0001] The utility model relates to the technical field of door bodies, and specifically relates to a door body with insulation and heat preservation functions. Background Art

[0002] The door body includes a door panel and a door frame. During use, the main function of the door body is to reduce the loss of indoor heat or cold air. Therefore, when the indoor temperature is higher or lower than the outdoor temperature, good heat preservation performance can reduce the transfer of indoor heat or cold air to the outside, thereby maintaining the stability of the indoor temperature. When the door body is in use, a sealing strip is generally installed on the door frame, which can effectively increase the sealing effect between the door panel and the door frame, and can also buffer the door panel when the door panel is closed.

[0003] When the existing sealing strip is in use, it is generally cut into four sections according to the width and height of the inner wall of the door frame, and then bonded to the inner wall of the door frame by means of double-sided tape to achieve the sealing between the door panel and the door frame. However, during the long-term use of the sealing strip, it will age under the influence of the surrounding environment, resulting in air leakage and dust leakage of the door body. At this time, a cutter is needed to cut the sealing strip and replace it with a new one. However, since the sealing strip is fixed by bonding, there will be residues of the sealing strip on the door frame. Based on this, a door body with insulation and heat preservation functions is provided now, which can eliminate the disadvantages of the existing device. Summary of the Utility Model

Through the plugging rubber cylinder 202, the sealing effect of the door frame 1 can be further improved when the door panel 3 is closed.

[0046] The above embodiment discloses a heat-insulating and insulating door body. Among them, when the present utility model is in use, the first sealing strip 4 and the second sealing strip 5 can be cut according to the width and height of the inner wall of the door frame 1, so as to adjust the lengths of the first sealing strip 4 and the second sealing strip 5. Push one positioning insert block 207 to insert one fixing pressing plate 203 into the inner cavity of one end of the first sealing strip 4. At this time, the end face of the first sealing strip 4 with multiple connecting through holes 208 is extruded. During this process, under the external force extrusion of the first sealing strip 4, the outer wall around one connecting through hole 208 deforms under the blockage of the fixing baffle 205. At this time, the deformation opening of one connecting through hole 208 expands. When the inner wall of the first sealing strip 4 is closely attached to the outer wall of one fixing pressing plate 203, the first sealing strip 4 restores elastically at this time, and sleeves the outer walls of the connecting block 204 and the fixing baffle 205 through one connecting through hole 208, so as to realize the convenient snap connection and docking of one positioning insert block 207 and one first sealing strip 4;

[0047] After repeating the above operations, the ends of the two first sealing strips 4 and the two second sealing strips 5 can be butted and fixed through the positioning insert block 207. At the same time, the ports of the first sealing strip 4 and the second sealing strip 5 can be plugged through the plugging rubber cylinder 202, so as to effectively improve the sealing effect of the first sealing strip 4 and the second sealing strip 5;

[0048] Then, push the first sealing strip 4 and the second sealing strip 5 into the interior of the door frame 1, and sleeve them on the outer wall of the limit frame 201. At the same time, push the plugging rubber cylinder 202 to insert the positioning plug 207 into the interior of the door frame 1, so as to preliminarily fix the positioning plug 207.

[0049] After that, push the bolt 206 through the plugging rubber cylinder 202 to the outside of the other end of the positioning plug 207, and rotate it to thread the bolt 206 with the door frame 1 until the bolt 206 contacts the inner wall of one end of the positioning plug 207, so as to quickly fix the positioning plug 207. At the same time, the fixing pressing plate 203 squeezes the outer walls of the ends of the first sealing strip 4 and the second sealing strip 5 driven by the positioning plug 207, so as to realize the efficient installation of the first sealing strip 4 and the second sealing strip 5.

[0050] When the first sealing strip 4 and the second sealing strip 5 are aged and cause air leakage and dust leakage after the door panel 3 is closed, reverse the above operations at this time, which can realize the convenient disassembly of the first sealing strip 4 and the second sealing strip 5, and effectively avoid the residues of the first sealing strip 4 and the second sealing strip 5 adhering to the inner wall of the door frame 1.

[0051] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present application can easily think of changes or substitutions, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the protection scope of the claims.
