Detailed Description

To make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As a specific embodiment of the present invention, referring to fig. 1a to 4c, a reversible door structure includes a door frame 1 and a door leaf 2, wherein the door leaf 2 is hinged to the door frame 1 after the door frame 1 is fixed. Specifically, as shown in fig. 1b and fig. 2a to 2e, a door connecting plate 3 is fixedly connected to an inner side surface of the door frame 1 along a vertical direction, a thickness of the door connecting plate 3 is smaller than a thickness of the door frame 1, a width of the door connecting plate 3 is slightly larger than a half of the thickness of the door 2, and the thickness of the door connecting plate 3 is designed to be smaller than the thickness of the door frame 1, so that a right-angle space can be formed between the door connecting plate 3 and the door frame 1, and the door 2 can be smoothly opened and closed. Preferably, the door leaf connecting plate 3 is connected with an inner side of the door frame 1 as a whole, that is, when the door leaf connecting plate 3 is manufactured, the door leaf connecting plate 3 and the door frame 1 are integrally formed, and the thickness of the door leaf connecting plate 3 is half of that of the door frame 1.

As shown in fig. 2b and fig. 2e, a door leaf detaching installation groove 6 is provided at the top of the door frame 1, the door leaf detaching installation groove 6 is right opposite to the door leaf connecting plate 3, and the door leaf 2 is detached from or installed on the door frame 1 through the door leaf detaching installation groove 6. In general, the width of the door removal installation groove 6 is designed to be 1cm to 2cm larger than the thickness of the door 2 in order to smoothly perform the installation and removal. In this embodiment, the width of the door leaf detachment installation groove 6 is designed to be 2cm larger than the thickness of the door leaf 2.

As shown in fig. 1c, fig. 2a and fig. 2d, for the overall aesthetic property of the doorframe 1, a limiting block 7 matched with the door leaf dismounting installation groove 6 is detachably installed on the door leaf dismounting installation groove 6. When the door leaf 2 is not required to be detached from or installed on the door frame 1, the door leaf detaching installation groove 6 is plugged by the limiting block 7, so that the door leaf is complete in appearance.

As shown in fig. 1a, 1b, 2a, 2c, 2d and 4b, a first hinge 4 is fixed on the door leaf connecting plate 3 near the top and bottom of the door frame 1, and the first hinge 4 includes a connecting shaft 401, and is rotatably connected to the second hinge 5 on the door leaf 2 through the connecting shaft 401. In the present embodiment, the first hinge 4 is fixed to the door connecting plate 3 by screws, thereby ensuring the reliability of fixing the first hinge 4. In order to ensure that the door leaf 2 can be installed in a matching manner with the first hinge 4 after being turned upside down, the distance from the first hinge 4 close to the top of the door frame 1 is the same as the distance from the first hinge 4 close to the bottom of the door frame 1, preferably, the distance from the first hinge 4 close to the top of the door frame 1 and the distance from the first hinge 4 close to the bottom of the door frame 1 are both 10cm to 15cm, and in the embodiment, the distance from the first hinge 4 close to the top of the door frame 1 and the distance from the first hinge 4 close to the bottom of the door frame 1 are both 15 cm.

As shown in fig. 1a, fig. 1b, fig. 3a, fig. 3b, fig. 3c, fig. 3d and fig. 4c, two second hinges 5 corresponding to two first hinges 4 on the door leaf connecting plate 3 are fixed on one narrow side of the door leaf 2, each second hinge 5 includes a connecting shaft insertion hole 501 with two through ends, and in order to ensure that the door leaf 2 can be installed in a matching manner with the first hinges 4 after being turned upside down, i.e. to ensure that the door leaf 2 cannot affect normal use when being turned, the axis of the connecting shaft insertion hole 501 and the center line of one narrow side of the door leaf 2 must be designed to be coincident. In the present embodiment, the second hinge 5 is fixed to one narrow side surface of the door 2 with a screw, thereby ensuring the reliability of connection. As shown in fig. 1b and 4a, the connection shaft 401 of the first hinge 4 is inserted into the corresponding connection shaft insertion hole 501 of the second hinge 5, so that the door 2 and the door frame 1 can be connected.

Referring to fig. 1a, 1c, 3a and 3c, in order to avoid the door handle from being operated in a direction unchanged after the door 2 is turned upside down, the door handle of the present invention employs an external pulling type door handle 8, which is similar to the handle structure of a car door, specifically, the external pulling type door handle 8 is provided on both the inner surface and the outer surface of the door 2, and the external pulling type door handle 8 is located at a middle position near the other narrow side position of the door 2.

When the orientation of the door leaf 2 needs to be changed, the door leaf 2 needs to be opened to 90 degrees, as shown in fig. 1 c; then, a limiting block 7 in the door leaf dismounting installation groove 6 above the door frame 1 needs to be taken down, wherein the upper and lower thickness of the door frame 1 is larger than the integral height of the hinge; at the moment, the door leaf 2 is lifted up by a hinge height, and then the door leaf 2 can slide out of the hinge and be taken down along the door leaf dismounting installation groove 6; then, the door leaf 2 is turned over, and the door leaf 2 slides into the hinge from the door leaf dismounting installation groove 6, so that the connecting shaft 401 of the first hinge 4 is inserted into the corresponding connecting shaft insertion hole 501 of the second hinge 5, and the connection between the door leaf 2 and the door frame 1 is completed; then, the limiting block 7 is installed, and installation can be completed. At this moment, the door leaf 2 is originally inward on one side outside, and the resident can paste indoor wall paper or other ornaments on inboard door leaf 2 in order to improve indoor pleasing to the eye degree. Simultaneously, originally, inside one side door leaf 2 is outside, and 2 surfaces of door leaf are comparatively clean and tidy, avoid being corroded, the pleasing to the eye degree of multiplicable outward appearance simultaneously.

Finally, it should be noted that: the above-mentioned embodiments are only specific embodiments of the present invention, which are used for illustrating the technical solutions of the present invention and not for limiting the same, and the protection scope of the present invention is not limited thereto, although the present invention is described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: any person skilled in the art can modify or easily conceive the technical solutions described in the foregoing embodiments or equivalent substitutes for some technical features within the technical scope of the present disclosure; such modifications, changes or substitutions do not depart from the spirit and scope of the embodiments of the present invention, and they should be construed as being included therein. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
