The telescopic ends of the spring telescopic rod 10 are rotatably connected to one end of the telescopic rod 11 via hinge blocks 9. The telescopic ends of the spring telescopic rod 10 are rotatably connected to the telescopic rod 11. The air supply pipe 13 is located to the right of the membrane cover 1. A support leg 12 is fixedly connected to the left side of the lower surface of the air supply pipe 13, and an inclined support leg 14 is fixedly connected to the right side of the lower surface of the air supply pipe 13. A rubber anti-slip pad 15 is fixedly connected to the lower end of the inclined support leg 14. There are two support legs 12 arranged symmetrically, and two inclined support legs 14 arranged symmetrically. Four rubber anti-slip pads 15 are provided and fixedly connected to the lower ends of the support legs 12 and the inclined support legs 14, respectively. The inner surface of the air supply pipe 13... A fan 16 is installed on the side wall. A funnel tube 17 is fixedly connected to the left end of the air supply pipe 13.

[0027] To facilitate the fixing of the thin film cover 1 and improve detection efficiency and accuracy, as shown in the attached figure... Figures 1 to 8The application adopts the following structure: through the arrangement of a membrane cover 1, a U-shaped clamping frame 4, a U-shaped clamping frame 5, a spring telescopic rod 10, a telescopic rod 11, a sliding block 20, a push rod 21, and a lead screw 22, the energy-saving building door and window airtightness testing equipment has the effect of facilitating the fixation of the membrane cover 1 and improving testing efficiency and accuracy. In actual use, the lengths of the U-shaped clamping frame 4 and the U-shaped clamping frame 5 are adjusted to fit the energy-saving building door and window frame. Then, the membrane cover 1 is placed on the energy-saving building door and window frame, and the U-shaped clamping frame 4 and the U-shaped clamping frame 5 are abutted against the right side of the membrane cover 1. Then, the air supply pipe 13 is placed in the middle of the right side of the membrane cover 1. Then, the end of the push rod 21 is snapped onto the outer surface of the telescopic rod 11, and the device is activated by cranking the handle 2. 3. Rotating the lead screw 22, through the transmission action between the lead screw 22 and the sliding block 20, will drive the sliding block 20 to move to the left. At this time, the two ends of the telescopic rod 11 will drive the telescopic ends of the four spring telescopic rods 10 to compress simultaneously. During compression, a thrust is generated at the hinge of the U-shaped clamping frame 4 and the U-shaped clamping frame 5, thereby pressing the U-shaped clamping frame 4 and the U-shaped clamping frame 5 against the outer surface of the membrane cover 1, clamping and fixing the membrane cover 1 to the frame of the energy-saving building doors and windows, thus achieving the effect of facilitating the fixation of the membrane cover 1. Then, the detection pressure is adjusted through the central control terminal 19, and then the fan 16 works, blowing air from the right end to the left end of the air supply pipe 13, thereby creating the required high-pressure environment in the space between the inside of the membrane cover 1 and the energy-saving building, through the spiral air pipe. The electronic barometer inside the central control terminal 19 can continuously monitor the pressure inside the membrane cover 1. The central control terminal 19 controls the operating efficiency of the fan 16. The high pressure inside the membrane cover 1 causes air to flow through the gaps in the energy-saving building's doors and windows to the other side of the building, resulting in air loss from the membrane cover 1. This lost air can be continuously replenished by the fan 16. When outside air flows from the air supply duct 13 to the left, it drives the detection end of the digital anemometer 18 to rotate, detecting the air intake speed and feeding the data back to the central control terminal 19. The central control terminal 19 calculates the air intake speed multiplied by the cross-sectional area of ​​the funnel tube 17 end to determine the air intake volume over a specified time. This air intake volume is the air volume that passes through the gaps in the energy-saving building. The airflow on the other side can be used to calculate the airtightness of the energy-saving building doors and windows. After the test, the device can be directly disassembled and folded without cleaning the adhesive strips. This improves the airtightness between the membrane cover 1 and the energy-saving building door and window frame, and improves the test accuracy. Specifically, through the coordinated arrangement of the membrane cover 1, the U-shaped clamping frame 4, the U-shaped clamping frame 5, the spring telescopic rod 10, the telescopic rod 11, the sliding block 20, the push rod 21, and the screw 22, the membrane cover 1 can be tightly abutted against the door and window frame or the surrounding wall during use, effectively preventing air leakage and saving the step of applying adhesive strips. After the test, there is no need to clean the adhesive residue, thus achieving the purpose of facilitating the fixation of the membrane cover 1 and improving the test efficiency and accuracy. Example 2

[0028] This utility model provides the following technical solution: A U-shaped abutment frame 4 has a U-shaped abutment frame 5 slidably connected to its inner wall. There are four U-shaped abutment frames 4 and four U-shaped abutment frames 5. One end of the U-shaped abutment frame 4 is hinged to one end of the adjacent U-shaped abutment frame 5 through a hinge block 9. One end of the U-shaped abutment frame 5 is hinged to one end of another U-shaped abutment frame 4 through a hinge block 9. A limiting groove 6 is provided on the outer surface of the U-shaped abutment frame 4. The outer surface of the threaded rod 7 is slidably connected to the inner wall of the limiting groove 6. One end of the tightening knob 8 abuts against the outer surface of the U-shaped abutment frame 4. A threaded rod 7 is fixedly connected to the outer surface of the U-shaped abutment frame 5. A tightening knob 8 is threadedly connected to the outer surface of the threaded rod 7. One end of the U-shaped abutment frame 4 is hinged to a hinge block 9 through a shaft.

[0029] To facilitate easy adaptation to energy-efficient building doors and windows of different sizes, as shown in the attached document... Figures 1 to 8 The application adopts the following structure: through the setting of a film cover 1, a U-shaped clamping frame 4, a U-shaped clamping frame 5, a limiting groove 6, a threaded rod 7, and a tightening knob 8, the airtightness testing equipment for energy-saving building doors and windows has the effect of being easy to adapt to energy-saving building doors and windows of different sizes. In actual use, the tightening knob 8 can be loosened to allow the U-shaped clamping frame 5 to freely expand and contract inside the U-shaped clamping frame 4, thereby adjusting the overall length of the U-shaped clamping frame 4 and the U-shaped clamping frame 5. After adjustment, the tightening knob 8 can be tightened, so that the four sets of U-shaped clamping frames 4 and U-shaped clamping frames 5 can be well adapted to energy-saving building door and window frames of different widths and lengths. That is, through the coordinated setting of the film cover 1, the U-shaped clamping frame 4, the U-shaped clamping frame 5, the limiting groove 6, the threaded rod 7, and the tightening knob 8, the purpose of being easy to adapt to energy-saving building doors and windows of different sizes is achieved.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
