[0004] Regarding the aforementioned technologies, the inventors believe that lightweight metal door and window frames in these technologies are generally welded, which makes it inconvenient to disassemble and assemble the door and window frames, thus reducing the practicality of the device.

[0005] The information disclosed in this background section is only intended to enhance the understanding of the background technology of this application, and therefore may include prior art that is not known to those skilled in the art. Utility Model Content

[0006] To address the problem that lightweight metal door and window frames in related technologies are generally welded, which makes disassembly and assembly of the door and window frames inconvenient and reduces the practicality of the device, this application provides a lightweight metal door and window frame.

[0007] The lightweight metal door and window frame provided in this application adopts the following technical solution:

[0008] A lightweight metal door and window frame includes two vertically parallel door and window vertical beams and two horizontally parallel door and window horizontal beams. The door and window horizontal beams are fixedly connected to the door and window vertical beams by a snap-fit ​​assembly. The snap-fit ​​assembly includes a snap-fit ​​block fixedly installed at the end of the door and window vertical beam. The snap-fit ​​block has a sliding groove inside, and snap-fit ​​posts are slidably arranged on both sides of the sliding groove. A spring is installed between the two snap-fit ​​posts. Both ends of the door and window horizontal beams have snap-fit ​​grooves and snap-fit ​​holes communicating with the snap-fit ​​grooves. The snap-fit ​​grooves cooperate with the snap-fit ​​blocks, and the snap-fit ​​holes cooperate with the snap-fit ​​posts.

[0009] Preferably, a first mounting groove is provided at the near end of the two door and window vertical beams, and a second mounting groove is provided at the near end of the two door and window horizontal beams.

[0010] Preferably, the deformation distance of the spring is greater than the sum of the movement distances of the two locking pins.

[0020] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0021] This application discloses a lightweight metal door and window frame, referring to... Figure 1-4It includes two vertically parallel door and window vertical beams 1 and two horizontally parallel door and window horizontal beams 2. The door and window horizontal beams 2 and the door and window vertical beams 1 are fixedly connected by a snap-fit ​​assembly 3. The snap-fit ​​assembly 3 includes a snap-fit ​​block 31 fixedly installed at the end of the door and window vertical beam 1. The snap-fit ​​block 31 has a sliding groove 311 inside. Snap-fit ​​posts 312 are slidably arranged on both sides of the sliding groove 311. A spring 313 is installed between the two snap-fit ​​posts 312. Snap-fit ​​grooves 22 and snap-fit ​​holes 23 communicating with the snap-fit ​​grooves 22 are opened at both ends of the door and window horizontal beams 2. The snap-fit ​​grooves 22 cooperate with the snap-fit ​​blocks 31, and the snap-fit ​​holes 23 cooperate with the snap-fit ​​posts 312.

[0022] Here, by installing snap-fit ​​blocks 31 at both ends of the door and window vertical beam 1, and by providing a sliding groove 311, a snap-fit ​​post 312, and a spring 313 inside the snap-fit ​​block 31, and by providing snap-fit ​​grooves 22 and snap-fit ​​holes 23 at both ends of the door and window horizontal beam 2, the snap-fit ​​block 31 can be inserted into the snap-fit ​​groove 22, and the snap-fit ​​post 312 can be inserted into the snap-fit ​​hole 23 under the elastic force of the spring 313, thereby enabling the splicing of the door and window horizontal beam 2 and the door and window vertical beam 1. Conversely, by pressing the snap-fit ​​post 312, the snap-fit ​​post 312 squeezes the spring 313 and retracts into the sliding groove 311, so that the door and window horizontal beam 2 can be separated from the door and window vertical beam 1, improving the convenience of disassembling and assembling the door and window horizontal beam 2 and the door and window vertical beam 1.

[0023] Reference Figure 2 and Figure 3 The two door and window vertical beams 1 are provided with a first mounting groove 11 near the end, and the two door and window horizontal beams 2 are provided with a second mounting groove 21 near the end.

[0025] Reference Figure 4 The deformation distance of spring 313 is greater than the sum of the movement distances of the two locking posts 312.

[0026] Here, by making the deformation distance of the spring 313 equal to the sum of the movement distances of the two locking posts 312, it is possible to avoid exceeding the elastic limit of the spring 313.

[0027] Reference Figure 1 The end of the snap-fit ​​post 312 is rounded.

[0028] Here, by rounding the end of the snap-fit ​​post 312, the door and window horizontal beam 2 is separated from the door and window vertical beam 1 when the snap-fit ​​post 312 is pressed.

[0029] The implementation principle of a lightweight metal door and window frame according to an embodiment of this application is as follows: In use, by installing snap-fit ​​blocks 31 at both ends of the door and window vertical beam 1, and by providing a sliding groove 311, a snap-fit ​​post 312 and a spring 313 inside the snap-fit ​​block 31, and by providing snap-fit ​​grooves 22 and snap-fit ​​holes 23 at both ends of the door and window horizontal beam 2, the snap-fit ​​block 31 is inserted into the snap-fit ​​groove 22, and the snap-fit ​​post 312 can be inserted into the snap-fit ​​hole 23 under the elastic force of the spring 313, thereby realizing the splicing of the door and window horizontal beam 2 and the door and window vertical beam 1. Conversely, by pressing the snap-fit ​​post 312, the snap-fit ​​post 312 squeezes the spring 313 and retracts into the sliding groove 311, so that the door and window horizontal beam 2 can be separated from the door and window vertical beam 1, improving the convenience of disassembling and assembling the door and window horizontal beam 2 and the door and window vertical beam 1.
