Description

Technical Field

[0001] The utility model relates to the technical field of adjustable door frame structures, in particular to an adjustable split door frame and wall fixing structure. Background Art

[0002] As a crucial component of a building, the door frame's structural design and assembly fit directly impact the door's overall performance and aesthetics. Traditional door frames are typically monolithic, with the door frame and wall structure integrally formed. This single door frame cannot accommodate glass partition walls of varying thicknesses, requiring custom door frames tailored to varying wall thicknesses, increasing production costs and installation complexity.

[0003] There are some adjustable door frame designs on the market, but most only rely on adding spacers to adjust the distance between the door frame and the wall. This method is not only cumbersome but also aesthetically pleasing. Furthermore, existing door frame structures often fail to consider the need for concealed assembly after the door frame is fixed to the wall, resulting in poor decorative effects near the door frame.

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] An adjustable split door frame and wall fixing structure, which adopts a split mechanism, please refer to Figure 1-2 It includes a group of relatively arranged split door frames, and a single split door frame includes a main frame 1 and a sub-frame 2, wherein the main frame 1 has a buckle 3 on the outside, and the sub-frame 2 includes a bayonet 4 on the upper portion. The main frame 1 is fixed to the wall, and the buckle 3 is engaged in the bayonet 4, thereby fixing the sub-frame 2 on the main frame 1, and the buckle 3 can be engaged in different depths in the bayonet 4 to adjust the distance between the two relatively far end faces of the main frame 1 and the sub-frame 2. The position of the corresponding door frame sub-frame 2 can be adjusted according to the thickness of the partition wall and then fixed. There is no need to design a special door frame for mold opening according to the thickness of the partition wall, so that the door frame can flexibly adapt to the installation of partition walls of different thicknesses.

[0024] Among them, the buckle 3 includes two oppositely arranged claws 31, and the outer wall of the claws 31 is provided with a number of male teeth 32 distributed at equal distances. The opposite two side surfaces inside the bayonet 4 are provided with a number of female teeth 41 distributed at equal distances. The male teeth 32 and the female teeth 41 are relatively embedded in each other's intervals to position the sub-frame 2 at a suitable position on the main frame 1 to adapt to walls of different thicknesses.

[0025] The main frame 1 includes a first plate surface 11 and a second plate surface 12 arranged relatively parallel. The first plate surface 11 is parallel to the extension direction of the buckle 3. The inner side of the bayonet 4 of the sub-frame 2 extends toward the main frame 1 with a connecting plate 21, and the connecting plate 21 is in contact with the second plate surface 12; a notch is provided on the first plate surface 11. During assembly, the claw 31 of the buckle 3 is first inserted into the bayonet 4 to a suitable depth to position the sub-frame 2, and then the main frame 1 and the sub-frame 2 are fixed to the wall. A hole is punched in the first plate surface 11 through the notch on the first plate surface 11 of the main frame 1. The punching position is located at the position where the connecting plate 21 and the second plate surface 12 are in contact with each other. The screw is inserted into the punched hole through the notch, and the screw is tightened on the wall to firmly lock the sub-frame 2 and the main frame 1.

[0026] In this embodiment, a slot 13 is formed on one side of the main frame 1. The slot 13 is located between the outer side surface of the sub-frame 2 and the first panel 11. A through hole 111 is formed on the first panel 11. The through hole 111 is offset from the notch. A hinge 5 is also included. During assembly, one side of the hinge 5 is passed through the slot 13 and inserted into the main frame 1. At this time, the pre-formed threaded hole on the hinge 5 is coaxially opposite to the through hole 111. A bolt passes through the through hole 111 and is threadedly connected to the threaded hole on the hinge 5, thereby fixing the hinge 5.

[0027] The first panel 11 is provided with snap-on ends 112 at both ends and includes an edge-sealing cover plate 7 that is shielded from the through-hole 111 and parallel to the first panel 11. The edge-sealing cover plate 7 is provided with receiving ends 71 at both ends that snap-on and connect with the snap-on ends 112. The snap-on ends 112 and receiving ends 71 are interlocking structures. After the secondary frame 2 is assembled, the edge-sealing cover plate 7 is snap-on and fixed to the front side of the main frame 1, shielding the bolts and realizing a concealed assembly method.

[0028] Furthermore, a notch 14 is formed in the main frame 1 on the other side, into which a locking plate 6 is placed. The locking plate 6 is fixed in position and has a recessed surface. The locking plate is integrally formed to the width and thickness of the door frame's side, eliminating the need for a separate locking plate hole in the door frame cover. The door body is fixed to the free side of the door frame, and the door lock is fixed to the side of the door body. The lock tongue can rotate with the door body and connect to the recessed structure of the locking plate 6.

[0029] The embodiments described above are merely descriptions of preferred embodiments of the present invention and are not intended to limit the concept and scope of the present invention. Any modifications and improvements to the technical solution of the present invention made by a person of ordinary skill in the art without departing from the design concept of the present invention shall fall within the scope of protection of the present invention. The technical content sought to be protected by the present invention is fully set forth in the claims.
