Description

Technical Field

[0001] The present invention relates to the technical field of glass door and window detection, and in particular to an on-site detection device for glass doors and windows. Background Art

[0002] Glass doors and windows primarily consist of an outer frame and the glass panels within it. During construction inspection and acceptance, these windows and doors must be tested on-site, with air tightness testing, thermal insulation testing, and impact resistance testing among the various tests performed. In the prior art, a door and window on-site air tightness tester, disclosed in Patent Publication No. CN218156682U, can be used on-site to test the air tightness of doors and windows.

[0003] When testing for air tightness, a common method is to first seal one side of the door or window with a sealing film using adhesive strips, then connect one end of the gas pipe to the interface on the sealing film, and use the testing host to test the airtightness of the door or window. This testing method relies on adhesive strips to secure the sealing film to the door or window, but its sealing strength is insufficient, making it impossible to perform airtightness testing with a higher air pressure. If the testing host inputs high-pressure gas through the gas pipe, the air pressure will cause the sealing film to separate from the door or window and leak, affecting the test results. In addition, when performing impact resistance testing, pressure needs to be applied to the glass plate. When the glass plate shatters under pressure, the glass fragments can easily fly and injure people. Summary of the Invention

[0027] Reference Figures 1 to 4 A multi-parameter on-site detection device for glass doors and windows is used to be installed on glass doors and windows. The glass doors and windows include a frame 11 and a glass plate 12 arranged inside the frame 11. The detection device includes a mounting frame 20, a sealing strip 31, a sealing film 32, a positioning assembly 40 and a wiring harness group 50. The front side of the mounting frame 20 has a sealing groove 22, the sealing strip 31 is embedded in the sealing groove 22, and the two ends of the sealing strip 31 are stacked. Among them, the installation frame 20 includes four telescopic frame strips 21 arranged in sequence into a rectangle, and corner heads 23 are connected between adjacent telescopic frame strips 21. The sealing film 32 is adhered to the front side of the sealing strip 31, and the sealing film 32 has a first mounting tube 321 and a ventilation interface 322 for connecting to the detection host. A positioning component 40 is provided on the outside of the telescopic frame strip 21. The wiring harness group 50 includes a plug sleeve 51 and a sensor wire 52 passed through the plug sleeve 51. A temperature probe is provided at one end of the sensor wire 52, and the temperature probe is provided on the front side of the sealing film 32.

[0028] Specifically, the ends of the telescopic bars 21 have notches, and the angled heads 23 are inserted into the notches of adjacent telescopic bars 21. The angled heads 23 are removably connected and locked to the ends of the telescopic bars 21 via bolts. This structure allows the mounting frame 20 to be assembled and disassembled, making the detection device portable. During installation, the temperature probe can be adhered to the sealing film 32.

[0029] During on-site work, the telescopic frame strip 21 is adjusted according to the size of the frame 11 so that the size of the installation frame 20 is adapted to the frame 11. A sealing strip 31 of appropriate length is selected or cut, and its ends are overlapped and embedded in the sealing groove 22. A sealing film 32 of appropriate size is selected, and glue is applied to the sealing strip 31 to form an adhesive layer. The adhesive layer is used to expand the sealing film 32 and adhere it to the sealing strip 31. The installation frame 20 is positioned on the frame 11 using the positioning assembly 40. Due to the height difference between the glass plate 12 and the frame 11, the sealing film 32, the glass plate 12, and the frame 11 enclose a test cavity. The testing host is connected to the vent port 322, and pressurized gas is introduced into the test cavity by the testing host and maintained at a pressure to test the sealing between the glass plate 12 and the frame 11. In addition, when it is necessary to test the thermal insulation performance, a heat source is placed on the side of the glass door and window facing away from the sealing film 32, and the temperature is detected by a temperature sensor. The thermal insulation performance of the glass door and window can be judged by detecting the temperature rise on the side of the glass door and window facing away from the heat source.

[0030] As described above, the sealing film 32 can be pressed onto the frame 11 by the sealing strip 31, thereby improving the bonding strength between the sealing film 32 and the glass door and window, and preventing the sealing film 32 from separating from the glass door and window due to air pressure, so that high-pressure gas can be passed between the sealing film 32 and the glass door and window for detection; the sealing film 32 can be stretched by adhering it to the sealing strip 31, thereby preventing its edge from wrinkling or not being pressed between the sealing strip 31 and the frame 11, and compared with manually using tape to seal the sealing film 32, the sealing film 32 can be stretched to prevent its edge from wrinkling or not being pressed between the sealing strip 31 and the frame 11. The tedious operation of sticking the sealing film on the glass doors and windows can be solved by the above structure with higher operating efficiency; the telescopic frame strip 21 can be adjusted in length to reduce the storage size of the installation frame 20, making it easier to carry the installation frame 20; the positioning component 40 can be used to position the installation frame 20 on the glass doors and windows to prevent the positioning component 40 from detaching, and there is no need to manually position the installation frame 20, thereby reducing labor intensity; when testing thermal insulation, the inflated sealing film 32 is used to carry the temperature sensor to prevent it from sticking to the glass doors and windows and affecting the detection effect.

[0031] Reference Figure 3 The two ends of the sealing strip 31 can be cut into oblique ends, and the two oblique ends are arranged in a superimposed manner.

[0032] In this embodiment, the telescopic frame bar 21 includes a first frame bar 211 and a second frame bar 212. The side wall of the first frame bar 211 has a guide groove, and the side wall of the second frame bar 212 has a guide portion 213. The guide portion 213 is slidably disposed in the guide groove, so that the first frame bar 211 and the second frame bar 212 can slide relative to each other and change the length of the telescopic frame bar 21. To lock the first frame bar 211 and the second frame bar 212, a fastening bolt can be screwed onto the first frame bar 211. When locking is required, the fastening bolt is tightened until its end abuts against the side wall of the second frame bar 212 or the guide portion 213.

[0033] In some embodiments, the guide groove may be provided on the second frame strip 212 , and the guide portion 213 may be provided on the first frame strip 211 .

[0034] In this embodiment, the sealing groove 22 includes a first groove 221, a second groove 222, a connecting groove 223 and a third groove 224. The first groove 221 is arranged on the front side of the first frame strip 211, the second groove 222 is arranged on the front side of the second frame strip 212, and the connecting groove 223 is provided in plurality and arranged in sequence along the guide groove. Each connecting groove 223 is arranged on the front side of the second frame strip 212, and one end of each connecting groove 223 is connected to one side of the second groove 222. The third groove 224 is provided on the front side of the corner head 23; when the guide portion 213 slides along the guide groove, the end of the first groove 221 can be connected to the other end of one of the connecting grooves 223, thereby facilitating the layout of the sealing strip 31.

[0035] In this embodiment, the positioning assembly 40 includes a positioning plate 41 and a bolt 42. The positioning plate 41 is located outside the telescopic frame strip 21. One end of the positioning plate 41 has a first positioning portion 411 located on the front side of the frame body 11, and the other end has a second positioning portion 412 located on the rear side of the telescopic frame strip 21. The bolt 42 is threadedly inserted into the second positioning portion 412 and abuts against the rear side of the telescopic frame strip 21. During installation, the bolt 42 is tightened so that the end of the bolt 42 presses against the telescopic frame strip 21, thereby positioning the mounting frame 20 on the glass door or window.

[0036] Furthermore, a positioning groove is formed on the rear side of the telescopic frame bar 21 , and the bolt member 42 is inserted into the positioning groove. The bolt member 42 can rotate in the positioning groove to limit the radial movement of the bolt member 42 .

[0037] In this embodiment, a rubber pad 43 is disposed inside the first positioning portion 411 to prevent the surface of the frame 11 from being damaged.

[0038] Reference Figure 5 and Figure 6 In some embodiments, a telescopic support rod 60 is further provided between the telescopic frame strips 21 on the left and right sides, one end of the telescopic support rod 60 is inserted into the telescopic frame strip 21 on the left, and the other end is inserted into the telescopic frame strip 21 on the right. A first through hole 641, a second through hole 642 and a third through hole 643 are provided on the telescopic support rod 60, the ventilation interface 322 is located in the first through hole 641, the first mounting tube 321 is located in the second through hole 642, the sealing membrane 32 has a second mounting tube 323, and the second mounting tube 323 is located in the third through hole 643, a bracket 651 is installed on the telescopic support rod 60, and a cylinder 652 is provided on the bracket 651, and the output end of the cylinder 652 is connected to a push rod 653, and the push rod 653 is passed through the second mounting tube 323.

[0039] The telescopic support rod 60 includes a first support rod 61 and a second support rod 62. One end of the first support rod 61 is inserted into the telescopic frame bar 21 on the left, and the other end is slidably connected to one end of the second support rod 62. The other end of the second support rod 62 is inserted into the telescopic frame bar 21 on the right. To lock the first support rod 61 and the second support rod 62, a fastening bolt can be screwed onto the first support rod 61. When locking is required, the fastening bolt is tightened until its end abuts the side wall of the second support rod 62.

[0040] A pressure plate 654 is provided at the end of the push rod 653 away from the cylinder 652, and a pressure sensor is mounted on the pressure plate 654. During impact resistance testing, the cylinder 652 applies force to press the pressure plate 654 against the glass sheet 12. The pressure sensor detects the pressure to test whether the glass sheet 12 will shatter within a set pressure range. If the glass sheet 12 shatters during testing, the sealing film 32 can block the flying debris, preventing it from injuring anyone. Furthermore, during field operations, if the glass door or window is wide and the distance between the telescopic frames 21 on the left and right sides needs to be increased, the telescopic support rod 60 can be installed to limit the height to which the sealing film 32 is lifted by the air pressure, thereby preventing the sealing film 32 from being damaged by the high pressure of the air.

[0041] Furthermore, the outer wall of the second mounting tube 323 has external threads, and the inner wall of the third through hole 643 has internal threads. A positioning tube 63 is inserted into the internal threads of the third through hole 643. The positioning tube 63 is threadedly mounted on the second mounting tube 323 and has a boss 631 extending to the rear side of the telescopic support rod 60. The positioning tube 63 is threadedly secured to the outer wall of the second mounting tube 323 and the inner wall of the third through hole 643, respectively. This prevents the push rod 653 from moving the second mounting tube 323 back and forth, which could cause damage to the sealing membrane 32.

[0042] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
