The end of the telescopic hose 208 far from the air pump 205 extends into the sliding groove 207 and is connected to one side of the sliding box 210.

[0046] The implementation method is specifically as follows: By setting the clamping and adsorption assembly 2, the staff drives the adsorption disc 212 to fit with the doors and windows through the rotating ring 201, the stroke groove 203, the stroke rod 209, the through groove 204, the sliding box 210, the sliding groove 207, the sliding box 210 and the connecting box 211. At the same time, the air pump 205 makes the inside of the adsorption disc 212 continuously in a vacuum state through the telescopic hose 208, the sliding box 210 and the connecting box 211, and adsorbs one side of the doors and windows to assist in the installation and positioning of the doors and windows. The staff drives the clamping plate 213 to move to one side by adjusting the lead screw 215, so that the clamping plate 213 gradually approaches the connecting box 211, and the detection doors and windows are fixed and limited by extrusion, ensuring the stability of the detection of the detection doors and windows and improving the stability of the detection data. By controlling the moving stroke of the sliding box 210, doors and windows of different specifications can be adapted, improving the applicability of the device.

[0047] The adjustment assembly 4 includes a first lead screw base 406 capable of driving the test fan 6 to move. The first lead screw base 406 is slidably connected to the test channel 1. The bottom of the first lead screw base 406 is in contact with the bottom inner wall of the test channel 1. Two symmetrically arranged moving lead screws 405 are rotatably connected inside the test channel 1. The moving lead screw 405 is threadedly connected to the first lead screw base 406. A plurality of ventilation grooves 407 are linearly arranged along the length direction on both sides of the test channel 1.

One end of the output shaft of the first motor 403 is connected to one end of one of the moving lead screws 405. One end of the other moving lead screw 405 extends outside the test channel 1 and is connected to a driven wheel 402. One end of the output shaft of the first motor 403 is connected to a driving wheel 404. A transmission belt 401 is connected between the driving wheel 404 and the driven wheel 402.

[0048] The implementation method is specifically as follows: By setting the adjustment assembly 4, the first motor 403 drives the two moving lead screws 405 to rotate through the driving wheel 404, the transmission belt 401 and the driven wheel 402. The moving lead screw 405 drives the test fan 6 to move through the first lead screw base 406, so as to adjust the distance between the test fan 6 and the detection doors and windows. And during this process, by controlling the distance between the test fan 6 and the detection doors and windows and the quantitative relationship between the air outlet groove and the air inlet groove, the wind force received by the detection doors and windows can be controlled, so that more accurate data can be obtained.

[0049] The wind direction adjusting component 5 includes a partition plate 501. The bottom of the partition plate 501 is connected to the top of the first lead screw base 406. Both sides and the top of the partition plate 501 are in contact with the inner wall of the test channel 1. A rotating cylinder 506 is rotatably connected inside the partition plate 501. A plurality of guide plates 507 are symmetrically distributed inside the rotating cylinder 506 and are used to cooperate with the rotation of the rotating cylinder 506 to adjust the test wind direction. Connecting shafts are connected to both sides of the guide plate 507. One end of the connecting shaft is rotatably connected to the inner wall of the rotating cylinder 506 through a bearing. One side of the guide plate 507 is hinged with a connecting rod 510. The end of the connecting rod 510 away from the guide plate 507 is hinged with a second lead screw base 509. A reciprocating lead screw 508 is threadedly connected inside the second lead screw base 509, and a plurality of reciprocating lead screws 508 are fixedly connected to each other. One end of the two innermost reciprocating lead screws 508 is rotatably connected to the same fixed rod. Both ends of the fixed rod are connected to the inner wall of the rotating cylinder 506. One end of the outermost reciprocating lead screw 508 extends outside the rotating cylinder 506 and is connected with a transmission gear 511. And the same fixed tooth disc 503 is meshed with one side of the two transmission gears 511. The fixed tooth disc 503 is connected to one side of the partition plate 501. A rotating tooth ring 502 is connected to the outer surface of the rotating cylinder 506. A second motor 504 is fixedly installed on one side of the partition plate 501 through a second mounting plate. One end of the output shaft of the second motor 504 is connected with a driving gear 505. One side of the driving gear 505 is meshed with the rotating tooth ring 502.

[0050] The specific implementation method is as follows: By setting the wind direction adjusting component 5, start the second motor 504. The second motor 504 drives the guide plate 507 to swing through the driving gear 505, the rotating tooth ring 502, the rotating cylinder 506, the reciprocating lead screw, the second lead screw base 509 and the connecting rod 510, so that the deflection direction of the guide plate 507 is changed, thereby being able to change the wind direction of the wind pressure blown out by the test fan 6, and thus being able to detect the wind pressure resistance of the test doors and windows in different directions. Through the inclination deflection of the guide plate 507 in cooperation with the rotation of the rotating cylinder 506 itself, the wind direction can be changed in all directions, thereby expanding the range of detected wind directions.

[0051] Working principle: When in use, the staff first installs the doors and windows to be tested on the clamping and adsorption assembly 2 to ensure the stability of the doors and windows to be tested during detection. The staff places the doors and windows to be detected at the center position of the fixed ring 202. The staff rotates the rotating ring 201, and the rotating ring 201 drives the travel groove 203 to rotate. The travel groove 203 drives the travel rod 209 to move in the through groove 204. The travel rod 209 drives the sliding box 210 to move in the sliding groove 207, so that the sliding box 210 drives the connection box 211 to move, and makes all around the doors and windows fit with the suction discs 212 on one side of the connection box 211. Moreover, during this process, the air pump 205 pumps air into the sliding box 210 and the connection box 211 through the telescopic hose 208, and keeps the inside of the suction discs 212 in a vacuum state all the time, so that the suction discs 212 adsorb one side of the doors and windows to assist in installing and positioning the doors and windows. After that, the staff rotates the adjustment screw rod 215, and the adjustment screw rod 215 drives the clamping plate 213 to move to one side, so that the clamping plate 213 gradually approaches the connection box 211, and completes the fixed limit of the detected doors and windows by extrusion, ensuring the stability of the detected doors and windows during detection.

[0052] During the test, the first motor 403 is started. The first motor 403 drives the driving wheel 404 to rotate. The driving wheel 404 drives the driven wheel 402 to rotate through the transmission belt 401. The driving wheel 404 and the driven wheel 402 respectively drive a moving screw rod 405 to rotate. The moving screw rod 405 drives the first screw seat 406 to move. The first screw seat 406 drives the test fan 6 to move, so as to adjust the distance between the test fan 6 and the detected doors and windows. And during this process, the partition plate 501 will divide the ventilation groove 407 into two parts, the front and the back. The part in front of the test fan 6 is the air outlet groove for air outlet, and the part behind the test fan 6 is the air inlet groove for air inlet. During the movement of the test fan 6, the number of the air inlet groove and the air outlet groove changes. The closer the test fan 6 is to the detected doors and windows, the fewer the air outlet grooves and the more the air inlet grooves. Therefore, the air inlet volume is much larger than the air outlet volume. And because the distance between the test fan 6 and the detected doors and windows is relatively close, the greater the wind force on the detected doors and windows, and vice versa, the smaller the wind force on the detected doors and windows.

[0053] During the detection process, the second motor 504 is started. The second motor 504 drives the driving gear 505 to rotate. The driving gear 505 drives the rotating toothed ring 502 to rotate. The rotating toothed ring 502 drives the rotating cylinder 506 to rotate. The rotating cylinder 506 drives a plurality of reciprocating screw rods 508 to rotate. The reciprocating screw rods 508 drive the second screw seat 509 to move. The second screw seat 509 drives the connecting rod 510 to swing. The connecting rod 510 drives the guide plate 507 to swing, so that the deflection direction of the guide plate 507 is changed, so as to be able to change the wind direction of the wind pressure blown out by the test fan 6, and thus be able to detect the wind pressure resistance of the detected doors and windows in different directions.

[0054] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
