[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] like Figure 1 As shown, a door opening 2 closing structure is provided in an embodiment of this utility model, which is disposed in the door opening 2. The door opening 2 closing structure includes:

[0027] Corner guard strip 21 is installed at the external corner of doorway 2;

[0028] Leveling layer 22 is laid on the inner surface of doorway 2 to smooth the inner surface of doorway 2;

[0029] The deformable connecting layer 23 is set on the leveling layer 22. The door frame is connected to the deformable connecting layer 23. The deformable connecting layer 23 undergoes corresponding deformation under the pressure of the door frame and the leveling layer 22, so that the door frame is stably installed in the door opening 2.

[0030] In this embodiment, the doorway 2 is opened on the wall 1, and the wall surface is painted with latex paint; the external corner of the doorway 2 refers to the outer corner where the vertical wall surfaces on both sides of the doorway 2 intersect with the top beam, that is, the external angle of the doorway 2 frame; the external corner usually needs to be wrapped with a special corner guard 21 (such as a metal corner guard 21 or a plastic corner guard 21) to avoid damage to the corner due to friction or bumps, and at the same time, it can also enhance the visual neatness and aesthetics; the leveling layer 22 can be a putty leveling layer 22, a gypsum leveling layer 22, a mortar leveling layer 22 or other types of leveling layer 22, which is not limited here.

[0031] In this application, the door frame can be bonded to the deformable connecting layer 23 by an adhesive (such as epoxy resin). The deformable connecting layer 23 can deform in different positions according to the shape of the gap between the door frame and the door opening 2, thereby forming sufficient filling in every gap between the door opening 2 and the door frame, so that the door frame can be firmly fixed in the door opening 2.

[0032] As a preferred embodiment, the edge of the inner surface of the door opening 2, i.e. the external corner of the door opening 2, is provided with corner guard strips 21 along the external corner line at each external corner of the door opening 2. The leveling layer 22 is laid on the inner surface area of ​​the door opening 2 between the corner guard strips 21, so that the inner surface of the door opening 2 is flush with the corner guard strips 21.

[0033] In this embodiment, after the corner guard strip 21 is installed at the external corner of the door opening 2, the wall surface where the corner guard strip 21 is located will form a protrusion, which will cause the inner surface of the door opening 2 (i.e. the inner contour surface of the door opening 2, i.e. the surface used to install the door frame) to form a relative depression. If the door frame is directly installed in this depression, the door installed later may also be blocked by the protruding corner guard strip 21. In this embodiment, the depression is filled by applying a leveling layer 22, which not only solves the above problem, but also maintains the aesthetics of the door opening 2.

[0034] In a preferred embodiment, the deformable connecting layer 23 is made of an elastically deformable material.

[0035] The deformable connecting layer 23 is a planar plate of a set thickness. The deformable connecting layer 23 is fully distributed on the inner surface of the door opening 2, and the edge of the deformable connecting layer 23 does not extend beyond the edge of the inner surface of the door opening 2.

[0036] In this embodiment, the elastic deformation material can be synthetic rubber or other materials, which are not limited here; the set thickness can be set to be slightly larger than the construction error of the door opening 2. For example, if the construction error of the door opening 2 is 3mm, it means that there may be a gap of less than 3mm between the door opening 2 and the door frame. At this time, the set thickness can be set to 4mm so that the deformation connection layer 23 can achieve interference filling in all gaps to ensure the stability of the door frame.

[0037] In a preferred embodiment, a plurality of mounting holes 24 are provided on the leveling layer 22, and a spring assembly is installed in each mounting hole 24, and the deformable connecting layer 23 is connected to the spring assembly.

[0038] The spring assembly includes:

[0039] A spring tube 25 is disposed in a mounting hole 24, with one end of the spring tube 25 being open.

[0040] The spring is connected at one end to the bottom of the spring tube 25 and at the other end to the deformable connecting layer 23.

[0041] The mounting hole 24 penetrates the leveling layer 22 and extends into the wall 1 by a set length. The length of the spring tube 25 is set to be consistent with the depth of the mounting hole 24, so that after the spring tube 25 is installed into the mounting hole 24, the bottom of the spring tube 25 abuts against the bottom surface of the mounting hole 24, and the opening of the spring tube 25 is flush with the opening of the mounting hole 24.

[0042] The diameter of the spring tube 25 is adapted to the diameter of the mounting hole 24, and the diameter of the spring is adapted to the diameter of the opening of the spring tube 25.

[0043] The length of the spring is set such that when the spring is at its compression limit, the length of the spring is exactly equal to the length of the Bourdon tube 25.

[0044] In this embodiment, the mounting holes 24 are evenly distributed on the leveling layer 22. The number of mounting holes 24 is determined according to the user's actual needs for the stability of the door frame and is not limited here. The diameter of the spring tube 25 is adapted to the diameter of the mounting hole 24, and the diameter of the spring is adapted to the diameter of the opening of the spring tube 25, so that the three can be stably nested to ensure the stability of the spring when it is working and to avoid the spring from bending or other situations. The length of the spring is set so that when the spring is at its compression limit, the length of the spring is exactly equal to the length of the spring tube 25, so that when the door frame is not deformed, each spring is always in a charged state. Once the door frame is deformed due to some reason (such as disrepair over the years or excessive load), the spring can push the deformation connecting layer 23 to move with the deformation of the door frame to maintain the support of the door frame and thus maintain the stability of the door frame.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
