[0033] The following will be combined with the drawings of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the embodiments described in the present application are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0034] Example 1

[0035] Door frame structure without installation holes

[0036] See also Figures 1 to 6 As described above, the hole-free door frame structure provided in the present application is suitable for curved doors, single-leaf doors, double-leaf doors, and double-leaf doors, etc.

[0037] Combination Figures 1 to 3The hole-free door frame structure includes a main frame 13, a sub-frame 14, a fixing plate 2 and a fixing component 6. The sub-frame 14 can be plugged into the main frame 13 and can be suitable for installation on walls 7 of different thicknesses. In this embodiment, the fixing component 6 can be an expansion bolt.

[0038] The main frame 13 includes a pressing portion 133 and a clamping portion 131, and a limiting portion 132 is provided between the pressing portion 133 and the clamping portion 131; the sub-frame 14 includes a second clamping plate 142 and a plug-in plate 141, the plug-in plate 141 is used to be plugged into the main frame 13, and the pressing portion 133 abuts against the plug-in plate 141 to press and fix the sub-frame 14.

[0039] The clamping portion 133 includes a second connecting plate 1332 and a clamping plate 1331; the clamping portion 131 includes a first clamping plate 1311 and a first connecting plate 1312 connecting the first clamping plate 1311 and the limiting portion 132, and the first clamping plate 1311 and the second clamping plate 142 are used to clamp the two sides of the wall 7;

[0040] One end of the fixing plate 2 is arranged on the clamping plate 1311, and a gap is provided between the fixing plate 2 and the connecting plate 1312. The gap between the fixing plate 2 and the connecting plate 1312 is used to avoid the protruding end of the expansion bolt. The plug-in plate 141 can be plugged into the main frame 1 along the space between the protruding end of the expansion bolt and the clamping portion 133.

[0041] The extended end 21 of the fixing plate 2 extends toward one side of the secondary frame 14 and extends out of the pressing portion 133 ; the fixing assembly 6 is disposed on the extended end 21 and is used to connect the main frame 13 to the wall 7 .

[0042] Combination Figure 3 and Figure 4 When the connecting plate 1312 is arranged in parallel with the fixing plate 2, it is assumed that: the gap width between the fixing plate 2 and the connecting plate 1312 is L, the width of the limiting portion 132 is L2, the width of the clamping plate 1331 is L1, the length of the fixing component 6 extending out of the fixing plate 2 is A, the thickness of the plug-in board 141 is B, and L≥A+B+L1-L2, so as to ensure that the sub-frame 14 can be inserted into the main frame 13.

[0043] During installation, the fixing assembly 6 is installed on the protruding end 21, and the door frame 1 is fixedly installed on the wall 7. After the gap between the main frame 13 and the fixing plate 2 is filled with foam glue, the sub-frame 14 is inserted into the main frame 13 to complete the installation of the door frame 1. The installation operation is simple and convenient, which can improve the installation efficiency and ensure that no installation holes are required on the main frame 13, so as to improve the overall aesthetics of the door frame 1 after the installation is completed.

[0044] Combination Figure 3 , and also includes a card plate 3, which is connected to the main frame 13 and is located between the pressing portion 133 and the limiting portion 132. A cavity 8 is formed in the card plate 3 to improve the strength of the main frame 1.

[0045] In order to prevent the sub-frame 14 from tilting after being inserted into the main frame 13, one end of the card plate 3 extends toward the clamping portion 133 to form a hook 3-1. After the main frame 13 is fixed, the plug-in board 141 is inserted into the cavity 8 and abuts against the hook 3-1. The clamping portion 133 abuts against and clamps the plug-in board 141, thereby limiting and supporting the plug-in board 141.

[0046] When the second clamping plate 142 clamps one side of the wall 7, the hook portion 3-1 abuts against and supports the plug-in board 141. The hook portion 3-1 and the clamping portion 133 can limit the rotation of the plug-in board 141, thereby ensuring that the plug-in board 141 is parallel to the wall 7 and preventing the secondary frame 14 from being inserted into the main frame 13 at an angle. The first clamping plate 1311 cannot clamp one side of the wall 7, thereby resulting in a gap between the main frame 13 and the secondary frame 14, resulting in a loose fit, which affects the overall aesthetics and use effect after installation.

[0047] Combination Figure 4 , the distance between the hook 3-1 and the pressing portion 133 is C, the thickness of the plug-in board 141 is B, and the distance C between the hook 3-1 and the outer edge of the pressing portion 133 is greater than or equal to the thickness B of the plug-in board 141, so that the sub-frame 14 can be smoothly plugged into the cavity 8; preferably, the distance C between the hook 3-1 and the pressing portion 133 is equal to the thickness B of the plug-in board 141, and on the premise that the sub-frame 14 can be smoothly inserted into the cavity 8, the main frame 13 and the sub-frame 14 can fit closely, and no noise will be generated during daily use. After installation, the overall appearance of the door frame 1 will not be deformed.

[0048] Combination Figure 3The clamping portion 133 includes a connecting plate 1332 and a clamping plate 1331. The main frame 13 and the sub-frame 14 are both integrated bending structures with high overall structural strength. The clamping plate 1331, the limiting portion 132 and the clamping plate 1 1311 are arranged in parallel. The fixing plate 2 is arranged in parallel with the connecting plate 1 1312.

[0049] Combination Figure 2 The main frame 13 is also rotatably connected to a door leaf 4 , and a rubber strip 9 for buffering is provided between the door leaf 4 and the limiting portion 132 , wherein the door leaf 4 and the main frame 13 can be rotatably connected via a hinge 5 .

[0050] Example 2

[0051] Door frame

[0052] like Figure 1 The door frame 1 structure includes a cross beam 11 and columns 12 connecting the two sides of the cross beam 11. In this embodiment, the columns 12 have the same structure as the cross beam 11. Both the cross beam 11 and the columns 12 adopt the hole-free door frame structure in Example 1.

[0053] Example 3

[0054] This embodiment changes the structure of the crossbeam 11 in the second embodiment to improve the overall structural strength and rigidity of the door frame 1 after installation, thereby enhancing the bearing capacity and stability of the door frame 1, as follows:

[0055] Combination Figures 3 to 6 As shown, Figure 4 Compared with the door frame 1 structure, one end of the fixed plate 2 in the beam 11 is connected to the connecting plate 1312 and the clamping plate 1311, a groove 22 is provided on the fixed plate 2, the sub-frame 14 is inserted in the groove 22, the clamping portion 133 abuts and clamps the sub-frame 14 to prevent the sub-frame 14 from shaking in the groove 22, and the clamping plate 3 is located between the clamping portion 131 and the clamping portion 133, and is used to connect the main frame 13 and the fixed plate 2; specifically, the groove 22 is provided on the other end of the fixed plate 2, the clamping portion abuts against the plug-in plate 141, the plug-in plate 141 is inserted in the groove 22, and the clamping plate 3 is provided on the main frame 13 and connected to the fixed plate 2 through the hook portion 3-1.
