TECHNICAL FIELD link

[0001] The present utility model relates to the technical field of door frame processing, and in particular to an improved door frame structure.

BACKGROUND ART link

[0002] In the prior art, a combined door frame is generally installed in such a manner that the door frame is assembled first, the frame strips on each side of the door frame are fixed by welding or threaded connection, and the door frame is then installed after the wall is constructed. A frequent problem with this assembly method is that after the door frame is fixed, the door is prone to failing to be installed, which requires complete disassembly and reconnection, consuming time and effort and seriously affecting the progress of the project. This situation urgently needs to be solved.

SUMMARY OF THE UTILITY MODEL link

[0003] Based on the above, an object of the present utility model is to provide a door frame structure, in which the connecting structure of the frame strips is adjusted to facilitate assembly and disassembly, thereby saving adjustment time.

The vertical frame strip A and the vertical frame strip B are disposed parallel to each other, and the horizontal frame strip is connected between the vertical frame strip A and the vertical frame strip B. The vertical frame strip A and the vertical frame strip B have the same structure. The vertical frame strip A and the vertical frame strip B each comprise a vertical U-shaped strip plate, a vertical profiled strip plate, and a plurality of spacers A. The vertical U-shaped strip plate and the vertical profiled strip plate are correspondingly fitted together so as to form a reserved groove. The spacers A are correspondingly arranged in sequence in an array along the length direction of the reserved groove, and the vertical U-shaped strip plate, the vertical profiled strip plate, and the plurality of spacers A form a mounting groove. The horizontal frame strip comprises a horizontal U-shaped strip plate, a horizontal profiled strip plate, and a plurality of spacers B. The horizontal U-shaped strip plate and the horizontal profiled strip plate are correspondingly fitted together so as to form a reserved groove, and the spacers B are correspondingly arranged in sequence in an array along the length direction of the reserved groove. A surface of one side of the vertical profiled strip plate along its length direction facing the horizontal profiled strip plate is provided with a plurality of insertion holes, and both ends of the horizontal profiled strip plate are provided with insertion hooks cooperating with the insertion holes. The insertion hooks are correspondingly inserted into the insertion holes to connect the vertical frame strip A, the horizontal frame strip, and the vertical frame strip B into a door frame structure.

[0005] As a preferred solution, the insertion holes are configured as flared insertion holes that are wide at one end and narrow at the other end, and the insertion hooks are configured in an arrowhead shape.

[0006] As a preferred solution, the horizontal profiled strip plate comprises a first L-shaped bent section, a second L-shaped bent section, and a connecting section A. The first L-shaped bent section is connected to the second L-shaped bent section through the connecting section A, and the insertion hooks are correspondingly disposed on two side surfaces of the connecting section A.

[0007] As a preferred solution, the vertical profiled strip plate comprises a third L-shaped bent section, a fourth L-shaped bent section, and a connecting section B. The third L-shaped bent section is connected to the fourth L-shaped bent section through the connecting section B.

[0008] As a preferred solution, each spacer A comprises a U-shaped section, a T-shaped extension section disposed on one side of the U-shaped section, and an L-shaped extension section disposed on the other side of the U-shaped section. The U-shaped section, the T-shaped extension section, and the L-shaped extension section are an integrally formed structure.

[0009] The present utility model has the following beneficial effects: the surface of one side of the vertical profiled strip plate along its length direction facing the horizontal profiled strip plate is provided with a plurality of insertion holes; both ends of the horizontal profiled strip plate are provided with insertion hooks cooperating with the insertion holes; and the insertion hooks are correspondingly inserted into the insertion holes to connect the vertical frame strip A, the horizontal frame strip, and the vertical frame strip B into a door frame structure. With this structural approach, the vertical frame strip A, the horizontal frame strip, and the vertical frame strip B can be easily disassembled and assembled, effectively solving the installation difficulty caused by the door being mounted last during assembly. With the door frame of the present structure, there is no need to disassemble the entire door frame and then assemble it together with the door; it is only necessary to disengage the insertion hooks of the vertical frame strip A or the vertical frame strip B and then correspondingly adjust the installation position, which is convenient and fast.
