Description

Technical Field

[0001] The utility model relates to a steel door, in particular to a new type of steel door. Background Art

[0002] The door is the outside that separates the indoor and outdoor. A sealing strip is installed on the door leaf or door frame.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0038] Secondly, the utility model is described in detail with schematic diagrams. When describing the implementation of the utility model, for the convenience of explanation, the cross-sectional diagrams showing the device mechanism will not be partially enlarged according to the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the utility model. In addition, in actual production, the three-dimensional space dimensions of length, width and depth should be included.

[0039] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] like Figures 1 to 5 As shown: a new type of steel door, comprising: a door frame 1, a door leaf 2, and a hinge 3, wherein the door frame 1 and the door leaf 2 are connected via the hinge 3, and a sealing strip assembly is arranged on the inner side of the door frame 1;

[0041] One side of the door frame 1 is a first side door frame 11, and the first side door frame 11 is provided with: a first step 12, a second step 13, and a third step 14;

[0042] The other side of the door frame 1 is a second side door frame 15, and the second side door frame 15 is provided with: a third sealing strip groove 16, a fourth step 17, and a first hinge block installation groove 18;

[0043] One side of the door leaf 2 is a first door leaf side edge 21, and the first door leaf side edge 21 is provided with a second sealing surface 23 and a third sealing surface 24;

[0044] The other side of the door leaf 2 is a second door leaf side edge 25, and the second door leaf side edge 25 is provided with a sealing protrusion 26, a hinge shaft groove 27, and a fourth sealing surface 28;

[0045] The inner end surface of the door leaf 2 is a first sealing surface 22;

[0046] The hinge 3 includes: a first hinge block 31, a second hinge block 32, and a hinge shaft 33.

[0047] The first hinge block 31 is arranged in the first hinge block installation groove 18 and connected to the first side door frame 11, the second hinge block 32 is connected to the second door leaf side 25, and the hinge shaft 33 is arranged in the hinge shaft groove 27 when the door is closed; the hinge shaft 33 is built into the hinge shaft groove 27 to avoid the hinge shaft 33 being externally placed, thereby increasing the anti-theft performance.

[0048] The sealing strip assembly comprises: a first sealing strip 5, a second sealing strip 6, a third concave sealing strip 7, and a fourth sealing strip 8;

[0049] The first sealing strip 5 is disposed at the first step 12 , and a first air chamber 51 is disposed inside the first sealing strip 5 .

[0050] The second sealing strip 6 includes: a second sealing section 61 and a third sealing section 63.

[0051] The second sealing section 61 is disposed at the second step 13 , and a second air chamber 62 is disposed in the second sealing section 61 .

[0052] The third sealing section 63 is disposed at the third step 14 ; a third air chamber 64 is disposed in the third sealing section 63 .

[0053] The third concave sealing strip 7 is embedded in the third sealing strip groove 16, and the fourth sealing strip 8 is arranged at the fourth step 17;

[0054] The first sealing surface 22 is tightly pressed and sealed with the first sealing strip 5, the second sealing surface 23 is tightly pressed and sealed with the second sealing section 61, and the third sealing surface 24 is tightly pressed and sealed with the third sealing section 63;

[0055] The fourth sealing surface 28 is tightly pressed and sealed with the fourth sealing strip 8. A seventh air chamber 81 is provided inside the fourth sealing strip 8. Because the fourth sealing strip 8 needs to avoid the installation position of the hinge 3, the sealing section of the fourth sealing strip 8 will have a gap at the installation position of the hinge 3, so there will be a sealing gap at the gap position, which reduces the overall sealing performance of the door.

[0056] Preferably, the third concave sealing strip 7 comprises: a fourth sealing section 71, a fifth sealing section 73, and a sixth sealing section 75. The fourth sealing section 71 is provided with a fourth air chamber 72, the fifth sealing section 73 is provided with a fifth air chamber 74, and the sixth sealing section 75 is provided with a sixth air chamber 76. The sealing scheme of the sealing protrusion 26 and the third concave sealing strip 7 being tightly pressed and sealed compensates for the sealing loss caused by the sealing notch of the fourth sealing strip 8.

[0057] The sealing strips on the inner sides of the upper and lower ends of the door frame are set as usual.

[0058] The utility model uses a third concave sealing strip 7 to compensate for the lack of the fourth sealing strip 8 at the hinge installation position, thereby solving the problem that the sealing effect of the existing door leaf 2 and door frame 1 through the sealing strip is insufficient due to the lack of the sealing strip at the hinge installation position, resulting in a gap in the seal.

[0059] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no mechanism conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
