[0003] Therefore, the above utility model patents have disclosed one technical solution for framed doors. However, the technical solution disclosed in the above utility model patents focuses on using a round dovetail to achieve a stable connection between the first and second frame sides, avoiding the conventional use of round dovetails for fixing. It does not further solve the problem of achieving accurate positioning at any position of the framed door, and needs further improvement. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing a stable support for framed doors.

[0005] This utility model adopts the following technical solution: a frame door stabilizing bracket, comprising a fixing structure and a positioning structure, wherein:

[0006] The fixed structure has a back body and two fixed semicircles. The two fixed semicircles are located on the same side of the back body and are integrally formed with the back body. There is a gap between the two fixed semicircles. The fixed semicircles are provided with fixed semicircle protrusions, which are integrally formed with the fixed semicircles.

[0007] The positioning structure has a back strip and a positioning semicircle integrally formed with the back strip. The top and bottom surfaces of the positioning semicircle have positioning semicircle grooves respectively. The positioning semicircle is partially connected to the gap, and the fixing semicircle protrusion is engaged with the positioning semicircle groove.

[0008] As a preferred technical solution to the above technical solutions, there is a gap between the fixed semi-circular protrusion and the back body, and there is a gap between the positioning semi-circular groove and the back strip.

[0009] As a preferred technical solution to the above technical solutions, the back panel has two back panel mounting holes with a gap between them.

[0010] As a preferred embodiment of the above technical solutions, the back strip has two back strip mounting holes with a gap between them.

[0011] As a preferred technical solution to the above technical solutions, the vertical distance between the two fixed semicircles is greater than the thickness of the positioning semicircle.

[0012] The stabilizing bracket for framed doors disclosed in this utility model has the advantage that the positioning structure can be flexibly adjusted relative to the fixed structure, enabling accurate positioning at any position on the framed door (especially when the door panel thickness is inconsistent). At the same time, the sliding adjustment function of the fixed semi-circular protrusion within the positioning semi-circular groove enhances adaptability and simplifies the positioning and fitting process.

Detailed Implementation

[0022] This utility model discloses a stabilizing bracket for a framed door. The following description, in conjunction with a preferred embodiment (Embodiment 1), is shown in the accompanying drawings. Figures 1 to 8 The specific embodiments of this utility model will be further described below.

[0023] See attached diagram. Figures 1 to 8 , Figures 1 to 4 The following images show the stabilizing brackets of the framed door from different perspectives. Figure 5 and Figure 6 The fixed structure is shown from different perspectives. Figure 7 and Figure 8 The positioning structures from different perspectives are shown.

[0024] Example 1.

[0025] Preferably, the frame door stabilizing bracket includes a fixing structure 100 and a positioning structure 200, wherein:

[0026] The fixing structure 100 includes a back body 110 and two fixing semicircular bodies 120. The two fixing semicircular bodies 120 are located on the same side of the back body 110 and are integrally formed with the back body 110. There is a gap 101 between the two fixing semicircular bodies 120. Each fixing semicircular body 120 has a fixing semicircular body protrusion 121, which is integrally formed with the fixing semicircular body 120. This is such that the fixing semicircular body protrusion 121 of one fixing semicircular body 120 is directly opposite the fixing semicircular body protrusion 121 of the other fixing semicircular body 120, which is equivalent to the two fixing semicircular body protrusions 121 being directly opposite each other.

[0027] The positioning structure 200 is provided with a back strip 210 and a positioning semicircular body 220 integrally formed with the back strip 210. The top and bottom surfaces of the positioning semicircular body 220 are respectively provided with positioning semicircular body grooves 221. The positioning semicircular body 220 is partially connected to the gap 101. The fixing semicircular body protrusion 121 is engaged with the positioning semicircular body groove 221. This allows the position of the positioning mechanism 200 to be flexibly adjusted relative to the fixing structure 100. It also allows the specific position of the fixing semicircular body protrusion 121 relative to the positioning semicircular body groove 221 to be slidably adjusted within the positioning semicircular body groove 221.

[0028] As an explanation, the fixing structure 100, as a component that maintains relative stability, can have its backing 110 externally attached to a stable external structure such as a wall. The positioning mechanism 200, as a component that can flexibly adjust its position, can have its backing strip 210 of the positioning structure 200 attached (installed) at any position on the frame door. By adjusting the relative position of the positioning structure 200 with respect to the fixing structure 100, accurate positioning of the frame door at any position can be achieved. Considering the actual situation that the thickness of the door panel may be inconsistent at different positions of the same frame door, when the backing strip 210 of the positioning structure 200 is attached (installed) at any position on the frame door, the flexible adjustment feature of the positioning mechanism 200 relative to the fixing structure 100 can be fully utilized to achieve accurate positioning of the frame door at any position.

[0029] There is a gap between the fixed semi-circular protrusion 121 and the back body 110, and there is a gap between the positioning semi-circular groove 221 and the back strip 210; so that only part of the positioning semi-circular 220 is connected to the gap 101.

[0030] The back cover 110 has two back cover mounting holes 111, with a gap between them; at the same time, the back cover mounting holes 111 are directly opposite the gap 101, which makes it convenient for the back cover 110 to be connected to an external structure such as a wall in a stable and unchanging position.

[0031] The back strip 210 has two back strip mounting holes 211 with a gap between them, making it convenient for the back strip 210 to be attached to (installed on) any position of the frame door.

[0032] The vertical distance between the two fixed semicircles 120 (equivalent to the vertical height of the gap 101) is greater than (slightly greater than) the thickness of the positioning semicircle 220; to avoid interference between the positioning semicircle 220 and the fixed semicircle 120.

[0033] It is worth mentioning that the specific materials and other technical features of the frame door stabilizing bracket involved in this utility model patent application should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement methods of these technical features can be conventionally selected in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0034] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
