Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0028] In order to enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.
[0029] Figure 1 A door and window sealing detection device is disclosed, in the embodiment, the detection of the air tightness of the window is aimed at, it needs to be pointed out that the sealing detection device is used for the door and window embedded in the wall, if the surface of the door and window is flush with the surface of the wall, then the traditional sealing detection device is still selected to detect the air tightness of the door and window.
[0030] As Figures 1-5 shown, the door and window sealing detection device includes two groups of support assemblies 2, the support assembly 2 includes a support rod one 21 and a support rod two 22 respectively, the support rod one 21 and the support rod two 22 are both L-shaped, the surface of the support rod one 21 is provided with a T-shaped sliding groove one 23, the surface of the support rod two 22 is fixedly installed with a sliding rod one 24 matched with the sliding groove one 23, the sliding rod one 24 is slidingly assembled in the inside of the sliding groove one 23, in the embodiment, two groups of sliding grooves one 23 are arranged on the surface of each support rod one 21, and the corresponding sliding rods one 24 are also arranged with two groups, the support rod one 21 and the support rod two 22 in the same group are slidingly assembled horizontally, the support rod one 21 and the support rod two 22 in different groups are slidingly assembled vertically, the outer side of the support rod one 21 and the support rod two 22 is bonded with a sealing strip 1, and the sealing strip 1 is attached to the inner side of the wall.
[0031] It needs to be explained that the surface of the support rod one 21 and the support rod two 22 is flush when adhering to the inside of the wall, and after the mutual sliding adjustment of the support rod one 21 and the support rod two 22, the support rod one 21 and the support rod two 22 are installed on the inside of the wall of different doors and windows, which can still ensure that the sealing strip 1 is tightly attached to the inside of the wall from the top to the bottom and the left and right sides of the wall, thereby ensuring the sealing property. In the embodiment, the surface of the support assembly 2 needs to be protruded from the surface of the wall of the door and window when being assembled, and the surfaces of the support rod one 21 and the support rod two 22 are flush.
[0032] In order to ensure that the support rod one 21 and the support rod two 22 are positioned in the appropriate position after sliding, the side of the support assembly 2 is equipped with a positioning assembly 7.
[0033] The outside of the support assembly 2 is equipped with a detection frame 3, the length and width of the detection frame 3 are greater than the standard size of the door and window, and the window is completely located on the inside of the detection frame 3 during detection. The surface of the detection frame 3 needs to adhere to the wall, and the surface of the detection frame 3 is bonded with a sealing rubber ring one 6, which adheres to the surface of the wall, thereby further improving the sealing property of the air tightness detection. It needs to be explained that the lower surface of the door usually needs to adhere to the ground, so when the air tightness of the door is detected, the bottom of the detection frame 3 can directly adhere to the ground. In order to ensure good sealing property during detection, the bottom of the detection frame 3 is also bonded with sealing rubber, thereby ensuring the sealing property when adhering to the ground during assembly.
[0034] The surface of the outside of the support rod one 21 is respectively provided with a T-shaped sliding groove two 8, and the inside of each sliding groove two 8 is slidably equipped with a sliding rod two 9. The end shape of the sliding rod two 9 is adapted to the shape of the sliding groove two 8.

The positioning assembly 7 includes a threaded rod 72, the sliding rod two 9 is slidably equipped on the surface of the detection frame 3, the end of the sliding rod two 9 is fixedly connected with a fixed plate 71, the threaded rod 72 is threadedly equipped on the surface of the fixed plate 71, and the end of the threaded rod 72 is rotatably installed on the surface of the detection frame 3. When the positions of the support rod one 21 and the support rod two 22 are adjusted, the threaded rod 72 can be rotated, and the threaded rod 72 also has a self-locking function. Therefore, when the support rod one 21 moves to the corresponding position, it will be automatically locked. At this time, the two support rod one 21s are positioned, and the two support rod two 22s also slide to adapt to the position of the support rod one 21.

The inside of the detection frame 3 is equipped with a pressing assembly 5, which presses the sealing film 4 to adhere to the surface of the support assembly 2, thereby further ensuring the sealing property during the air tightness detection.
[0036] The pressing assembly 5 comprises a pressing frame 51, which is of a certain width and can be attached to the surface of the support rod one 21 and the support rod two 22 within the range of movement adjustment of the support rod one 21 and the support rod two 22. Four corners of the pressing frame 51 are provided with grooves 11. The surface of the detection frame 3 is fixedly connected with four mounting plates corresponding to the positions of the four grooves 11. The surface of the mounting plate is threadedly connected with a stud 52. The end of the stud 52 is rotatably connected with an extrusion column 12. The extrusion column 12 abuts against the inner wall of the groove 11. When the pressing frame 51 is in the pressing state or the non-pressing state, the extrusion column 12 is located inside the groove 11, so as to ensure that the pressing frame 51 will not fall off when the entire detection device is carried. The surface of the pressing frame 51 is bonded with a sealing rubber ring two 10. When the pressing frame 51 is in the pressing state, the sealing rubber ring two 10 extrudes the sealing membrane 4 to be attached to the surface of the support rod one 21 and the support rod two 22.
[0037] When the attachment is performed, the staff needs to first arrange the sealing membrane 4 attached to the surface of the support rod one 21 and the support rod two 22 to be flat, and then rotates the four studs 52 respectively to drive the extrusion column 12 to extrude the pressing frame 51, so as to uniformly extrude the four corner positions of the pressing frame 51, so as to ensure that the pressing frame 51 can extrude the sealing membrane 4 to be uniformly attached to the surface of the support rod one 21 and the support rod two 22. When the unlocking is performed, the studs 52 only need to be reversely rotated.
[0038] In the embodiment, the sealing strip 1 on the side surface of the support rod one 21 and the support rod two 22 is attached to the inner side of the wall, and the position of the support rod one 21 and the support rod two 22 is locked by the threaded rod 72, so as to ensure that the sealing strip 1 is more closely attached to the wall, thereby ensuring the sealing performance when the device is installed in the air tightness detection. The extrusion column 12 is moved by rotating the stud 52, the pressing frame 51 is extruded, the sealing rubber ring two 10 is attached to the surface of the sealing membrane 4, the sealing membrane 4 is attached to the surface of the support rod one 21 and the support rod two 22, so as to further improve the sealing performance when the device is installed in the air tightness detection. When the support rod one 21 and the support rod two 22 are assembled, the sealing rubber ring one 6 on the surface of the detection frame 3 is attached to the surface of the wall, so as to further improve the sealing performance during the assembly. At this time, there are three sealing paths for the gas overflow path during the air tightness detection, and the multiple sealing paths are combined to ensure the sealing performance during the air tightness detection.
