Technical Field

[0001] The present application relates to a door and window detection device, and more particularly to a door and window multifunctional detection device. Background Art

[0002] Doors and windows are known as the eyes of buildings and are an important part of buildings. They not only provide rich decorative effects for the facades of buildings, but are also an important part of controlling building energy consumption. When doors and windows leave the factory, they need to be tested for their performance, mainly for three properties tests. The three properties tests specifically refer to the wind pressure resistance, air permeability, and rainwater leakage resistance of doors and windows. In construction, they are also referred to as wind pressure resistance, air tightness, and water tightness. Wind pressure resistance refers to the ability of external doors and windows to not be damaged (such as cracking, panel damage, local yielding, bonding failure, etc.) and hardware loosening, difficulty in opening, and other functional obstacles under the action of wind pressure when they are normally closed; air permeability refers to the ability of external doors and windows to prevent air infiltration when they are normally closed; rainwater leakage refers to the ability of external doors and windows to prevent rainwater leakage under the simultaneous action of wind and rain when they are normally closed.

[0003] During the inspection, it is necessary to first install the doors and windows to be inspected on the wall to form the test pieces, and then use the inspection equipment to inspect the test pieces. Since three property tests are required, the test pieces that have been inspected once need to be transported to the next inspection site for inspection, resulting in low inspection efficiency.

[0004] In order to improve the problem of low efficiency in detecting doors and windows, the present application provides a multifunctional detection device for doors and windows.

[0005] The present application provides a multifunctional door and window detection device that adopts the following technical solution:

[0017] In a specific embodiment, the test assembly includes a differential pressure sensor disposed on the test box and used to detect the pressure in the test box.

[0018] By adopting the above technical solution, when the fan blows air into the test box, the valve is closed, and the pressure difference between the test box and the outside air pressure is sensed by the pressure difference sensor, so as to detect the air tightness of the test piece to be tested.

[0019] In a specific possible implementation manner, the detection assembly includes a plurality of displacement sensors arranged on a frame for detecting the displacement of the test piece to be detected.

[0020] By adopting the above technical solution, when conducting water tightness and wind pressure resistance tests, the displacement of the test piece to be tested is detected by using a displacement sensor, so that the test result of the test piece to be tested can be obtained conveniently and quickly.

[0021] In a specific possible implementation scheme, the frame is provided with a base, the base is provided with a slide groove, and a roller that slides in the slide groove is rotatably provided on the bottom wall of the test box;

[0022] The power assembly comprises a power electric cylinder arranged on the base, and the end wall of the piston rod of the power electric cylinder is connected to the test box.

[0023] By adopting the above technical solution, when the test piece to be tested needs to be tested, the power electric cylinder pushes the test box to move and makes the test box contact with the fixed frame, so that the test can be carried out conveniently and quickly;

[0024] When the test is completed, the power cylinder drives the test box to move so that it can be separated from the fixed frame to facilitate the replacement of the next test piece to be tested.

[0025] In a specific possible implementation scheme, the cylinder body of the power electric cylinder is hingedly connected to the base, a hinge shaft is rotatably connected to the end wall of the piston rod of the power electric cylinder, a linkage rod is provided on the hinge shaft, the linkage rod is hingedly connected to the test box, at least two pushing rods are rotatably connected to the hinge shaft, and the linkage rod is located between the two pushing rods;

[0026] A sliding groove is provided on one side of the test box close to the base, a sliding block is slidably provided in the sliding groove, and one end of the pushing rod away from the hinge shaft is hingedly connected to the sliding block;

[0027] A limiting groove is provided on one side of the base close to the fixed frame, a movable plate is slidably provided on one side of the limiting groove close to its own notch, a vertical plate for the test box to move is provided on the movable plate, two connecting springs are provided on the side of the movable plate away from the vertical plate, one end of the connecting spring away from the movable plate is connected to the wall of the limiting groove, and the axis of the connecting spring is parallel to the moving track of the test box;

[0028] A clamping strip for contacting the test box is provided in the limiting groove for sliding movement, the clamping strip is located between the two connecting springs, a reset spring is provided between the clamping strip and the bottom wall of the limiting groove, the axis of the reset spring is perpendicular to the moving trajectory of the test box, the side of the clamping strip away from the reset spring contacts the sliding block, and the side of the clamping strip away from the reset spring is provided with a limiting notch for inserting a moving plate.

[0029] By adopting the above technical solution, when the power electric cylinder pushes the moving box to move, the hinge shaft contacts the side wall of the test box, thereby pushing the test box to move, the test box pushes the vertical plate to move, the vertical plate pulls the moving plate to move, the connecting spring stretches and stores force, and makes room for the movement of the tightening strip, and the reset spring can extend the tightening strip out of the limit groove, and the tightening strip contacts the side wall of the test box, so that the test box can be pressed against the fixed frame, which can reduce the possibility of air leakage between the test box and the fixed frame on the one hand, and reduce the possibility of the test box retreating when water or wind blows towards the test piece to be tested on the other hand;

[0030] When the test box needs to be reset, the power electric cylinder drives the hinge shaft to move downward, thereby driving the linkage rod to rotate and driving the pushing rod to move downward at the same time. The pushing rod drives the sliding block to slide along the sliding groove. The pushing rod pushes the tightening strip downward, and the reset spring is compressed and accumulates force. When the tightening strip moves down until its top wall is flush with the top wall of the moving plate, the power electric cylinder can drive the test box to reset. At the same time, the connecting spring pulls the moving plate, and the moving plate is inserted into the limiting notch, so that the tightening strip can be positioned in the limiting groove and the moving plate can be reset at the same time. In this way, the test box can be fixed repeatedly.

[0032] An air bag for inserting into the receiving groove is arranged on one side of the test box close to the fixed frame, an air pump for inflating the air bag is arranged on the frame, the air pump is connected to the air bag through an inflation hose, and a plug plate for inserting into the receiving groove is arranged in the air bag.

[0033] By adopting the above technical solution, since the test box and the fixed frame are only in contact with each other through the tightening strip, there may be gaps between the other three surfaces of the test box and the fixed frame. Therefore, when the test box is in contact with the fixed frame, the plug-in plate is inserted into the receiving groove, and the airbag is inserted into the receiving groove at the same time. The air pump then inputs air into the airbag along the inflation hose, and the airbag fills the receiving groove after being inflated, thereby reducing the possibility of air leakage between the test box and the fixed frame, thereby improving the detection effect.

[0034] In summary, the present application includes at least one of the following beneficial technical effects:

[0035] 1. First, install the test piece to be tested on the fixed frame, use the power component to drive the test box to move and contact the fixed frame, then use the water spray component to perform a water tightness test on the test piece to be tested, and use the wind pressure component to perform a wind pressure resistance test on the test piece to be tested. At the same time, use the detection component to detect the displacement of the test piece to be tested, and then use the test component to detect the air tightness of the test piece to be tested. This can replace the method of conducting multiple tests, which is conducive to improving the efficiency of the test;

[0036] 2. When the test piece needs to be tested, the power cylinder pushes the test box to move and make the test box contact with the fixed frame, so that the test can be carried out conveniently and quickly; when the test is completed, the power cylinder drives the test box to move, so that it can be separated from the fixed frame, which is convenient for replacing the next test piece to be tested;

[0037] 3. Since the test box and the fixed frame are only in contact with each other through the tightening strip, there may be gaps between the other three surfaces of the test box and the fixed frame. Therefore, when the test box is in contact with the fixed frame, the plug-in plate is inserted into the receiving groove, and the airbag is inserted into the receiving groove at the same time. The air pump then inputs air into the airbag along the inflation hose. After the airbag is inflated, the receiving groove is filled, thereby reducing the possibility of air leakage between the test box and the fixed frame, thereby improving the detection effect.

When spraying water, the fan 70 can simultaneously input wind into the test box 4 along the air outlet pipe 71 and the air supply pipe 73, so that a wind and rain mode can be performed, which can simulate natural conditions and better test the performance of the test piece 2 to be tested.

[0070] When the nozzle 66 sprays water toward the test piece 2 to be inspected, the driving motor 401 drives the driving shaft 402 to rotate, thereby driving the driving gear 403 to rotate, and then driving the moving rack 48 to move, and then driving the driven gear 400 to rotate, thereby driving the rotating disk 46 to rotate, and then driving the inclined rod 44 to rotate, thereby driving the nozzle 66 to rotate at multiple angles, and the left and right movements of different moving racks 48 can be staggered with each other, so that rainwater in different directions can be simulated, and the natural environment mode of wind and rain can be better simulated, and the water tightness of the test piece 2 to be tested can be detected at multiple angles, which is conducive to further improving the test effect.

[0071] When it is necessary to test the wind pressure resistance, the fan 70 blows wind into the test box 4 along the air outlet pipe 71 and the air supply pipe 73, and the displacement sensor 90 is used to monitor the displacement data of the test piece 2 to be tested, so as to detect the wind pressure resistance performance of the test piece 2 to be tested. The greater the moving distance, the weaker the wind pressure resistance performance.

[0072] When the fan 70 blows wind into the test box 4 and closes the valve 72, the pressure difference sensor 80 is used to detect the air pressure value in the test box 4, so that the water tightness, wind pressure resistance and air tightness of the test piece 2 to be tested can be tested at the same time, instead of changing the testing site, which is beneficial to improving the testing efficiency.

[0073] The implementation principle of a multifunctional detection device for doors and windows in an embodiment of the present application is as follows: when detection is required, firstly, the test piece 2 to be detected is installed on the fixed frame 3, and the power component 5 is used to drive the test box 4 to move and contact the fixed frame 3, and then the water sprinkling component 6 is used to perform a water tightness test on the test piece 2 to be detected, and the wind pressure component 7 is used to perform a wind pressure resistance test on the test piece 2 to be detected, and at the same time, the detection component 9 is used to detect the displacement of the test piece 2 to be detected, and then the test component 8 is used to detect the air tightness of the test piece 2 to be detected, which can replace the method of conducting multiple tests, which is beneficial to improving the efficiency of the test.

[0074] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
