Description

Technical Field

[0001] The invention relates to the technical field of door and window performance detection, and in particular to a device for detecting the physical properties of doors and windows. Background Art

[0002] Physical testing of doors and windows refers to a series of tests and evaluation activities on the physical properties of door and window products. These tests usually include but are not limited to the wind pressure resistance, air tightness, water tightness, thermal insulation (also known as heat insulation), sound insulation and lighting performance of doors and windows, etc., aiming to ensure that doors and windows can meet relevant quality standards and functional requirements in actual applications.

[0003] Patent application number CN202210509143.X provides a three-property detection sealing device for building doors and windows, including an outer frame for supporting a detection device; a positioning pressure plate installed in the outer frame for fixing the doors and windows, the positioning pressure plates are staggered on the outside of the doors and windows; a buckle box that provides space for the three-property detection operation of the doors and windows, and an auxiliary sealing mechanism for sealing the gap between two adjacent positioning pressure plates, the auxiliary sealing mechanism including a filler for filling the gap; by arranging staggered positioning pressure plates to press against the outside of the doors and windows, after the movable pressure plate is moved and fixed, the positioning pressure plate is fixed on the outside of the doors and windows, and the door and window installation work before the three-property test is completed. The device can be adjusted steplessly and is suitable for doors and windows of different sizes. It has a wide range of applications, and the positioning pressure plate can completely cover the surrounding sides of the doors and windows and doors and windows of all thicknesses. The surrounding sides of the doors and windows are more tightly sealed, and during detection, the overall force on the outside of the doors and windows is more uniform.

[0047] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the following will clearly and completely describe the technical solutions in the embodiments of the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention.

When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are only for the purpose of illustration.

[0049] As Figures 1 to 10 shown, a detection device for the physical properties of doors and windows according to the present invention includes: a box body 1, a fan 2, a pushing mechanism 3, a fixing mechanism 4, and a fan adjustment mechanism 5;

[0050] An installation opening 11 is provided on the box body 1; the pushing mechanism 3: conveys the door and window to be detected into the box body 1; the pushing mechanism 3 includes: a box buckle 31, a clamping component for pushing the box buckle 31 to be clamped with the box body 1, a door and window suction component 33 slidably connected to the box buckle 31, and a power source for pushing the suction component 33 to abut the door and window against the installation opening 11; the clamping component includes: a cylinder two 321 fixedly installed on the box body 1, and the telescopic rod of the cylinder two 321 is fixedly connected to the box buckle 31; both sides of the installation opening 11 are inclined surfaces 111 that gradually approach from the outside to the inside, and the two inclined surfaces 111 are stepped.

[0051] When it is necessary to transport the doors and windows, it is only necessary for workers to carry the doors and windows into the buckling box 31, and the vacuum suction cups in the buckling box 31 suck the doors and windows to be detected. When it is necessary to fix the doors and windows on the installation opening 11 of the box body 1, the second cylinder 321 resets and drives the buckling box 31 to approach the box body 1 synchronously, so that the buckling box 31 is engaged with the box body 1, thereby ensuring that the doors and windows to be detected are in a stable state without external interference, and further improving the accuracy and efficiency of the entire detection process. After the buckling box 31 is engaged with the box body 1, the power source pushes the vacuum suction cup and the adsorbed doors and windows to move from the installation opening 11 into the box body 1. After the doors and windows are fixed by the subsequent fixing mechanism 4, the vacuum suction cup stops adsorbing the doors and windows and moves away from the doors and windows, so as not to cause interference during the detection of the doors and windows.

[0052] It should be noted here that since the two sides of the installation opening 11 are inclined surfaces 111 that gradually approach from the outside to the inside, when the sizes of the doors and windows are different, the distances at which the doors and windows to be detected are completely in contact with the two inclined surfaces 111 of the installation opening 11 under the push of the power source are different. At the same time, the setting of the two inclined surfaces 111 can adapt to doors and windows of different sizes, enhancing the versatility of the installation opening 11, enabling it to adapt to a variety of different specifications of doors and windows, and thus significantly improving the flexibility and adaptability during the installation and detection of doors and windows.

[0053] Moreover, with the two sides of the installation opening 11 being inclined surfaces 111 that gradually approach from the outside to the inside, when the airflow generated by the fan 2 flows along the inclined surfaces 111, the wind can converge more concentratedly on the window surface. This not only improves the test accuracy, ensuring the accuracy and reliability of simulating the actual wind pressure environment, but also optimizes the test efficiency, shortening the test cycle by reducing the required air volume. At the same time, this design enhances the safety of the test, making the pressure distribution on the doors and windows during the test more uniform and reducing the risk of damage. In addition, the inclined surface 111 design also ensures that similar airflow conditions are obtained for doors and windows of different sizes during the test, improving the consistency and comparability of the test results.

[0054] The fixing mechanism 4: automatically fixes the doors and windows of different sizes transported into the box body 1; the fixing mechanism 4 includes: a first cylinder 41 fixedly connected to the top of the box body 1, a baffle 42 slidably installed at the installation opening 11, and a positioning component 43 for positioning the doors and windows when the baffle 42 presses down on the doors and windows; the piston rod of the first cylinder 41 is fixedly connected to the baffle 42, and the positioning component 43 is slidably installed at the bottom of the box body 1; the second cylinder 321 is started to make the baffle 42 press down on the doors and windows and drive the positioning component 43 to center the doors and windows.

[0055] When the door or window to be detected is pushed to the installation opening 11 of the box body 1 and fits against the inclined surface 111, the first cylinder 41 pushes the baffle 42 downward, causing the baffle 42 to engage with the upper end surface of the door or window, thus completing the preliminary fixation of the door or window in the up, down, left, and right directions. It should be noted here that the baffle 42 is the same size as the installation opening 11, and a sealing gasket is installed between the baffle 42 and the inclined surface 111 of the installation opening 11. Therefore, when the first cylinder 41 pushes the baffle 42 downward, the baffle 42 and the inclined surface 111 of the installation opening 11 can achieve a good sealing effect.

[0056] The positioning assembly 43 includes: a bottom plate 431, a trapezoidal groove 432 formed in the bottom plate 431, a clamping plate 433 slidably installed on the bottom surface of the trapezoidal groove 432, a pressing plate 434 elastically installed in the trapezoidal groove 432, and a pressure-receiving member 435 that drives the clamping plate 433 to move towards each other as the pressing plate 434 moves downward; the pressure-receiving member 435 is composed of a fixed portion 4352, a sliding portion 4351, and a second return spring 436 that drives the sliding portion 4351 to reset; the installation portion of the pressure-receiving member 435 is fixedly connected to the pressing plate 434; the sliding portion 4351 of the pressure-receiving member 435 abuts against the inclined surface 111 of the trapezoidal groove 432, and at the same time, the sliding portion 4351 of the pressure-receiving member 435 also abuts against the clamping plate 433; when the door or window presses down the pressing plate 434, the clamping plate 433 clamps the door or window on the pressing plate 434 in the center under the push of the pressure-receiving member 435.

[0057] When the first cylinder 41 pushes the baffle 42 downward, it will press down on the door or window, and the pressed door or window will compress the pressing plate 434 in the bottom plate 431, causing the pressing plate 434 to move downward in the trapezoidal groove 432 of the bottom plate 431. The pressure-receiving member 435 moves downward with the pressing plate 434. At this time, the sliding portion 4351 of the pressure-receiving member 435 gradually retracts into the installation portion of the pressure-receiving member 435 under the abutment of the trapezoidal groove 432. Since the sliding portion 4351 of the pressure-receiving member 435 also abuts against the clamping plate 433, when the pressure-receiving member 435 is squeezed inward by the trapezoidal groove 432 and retracts, it simultaneously drives the clamping plate 433 to slide towards each other at the bottom of the trapezoidal groove 432 until it abuts against the door or window on the pressing plate 434, clamping and fixing the door or window on the pressing plate 434 in the center; thus preventing potential damage risks caused by unstable or inclined fixation of the door or window during subsequent wind pressure testing of the door or window, and ensuring the accuracy and reliability of the test results; finally, after the door or window is detected, driven by the pressing plate 434 elastically installed in the trapezoidal groove 432, the door or window is ejected from the trapezoidal groove 432 to facilitate the loading and unloading of the detected door or window. At the same time, when the pressing plate 434 resets, it drives the pressure-receiving member 435 to move upward. The sliding portion 4351 of the pressure-receiving member 435 ends its restraint on the inclined surface 111 of the trapezoidal groove 432, and the second return spring 436 drives the sliding portion 4351 of the pressure-receiving member 435 to reset. At the same time, the sliding portion 4351 of the pressure-receiving member 435 drives the clamping plate 433 to reset.

[0058] It should be added here that after the buckling box 31 is engaged with the box body 1, when the power source drives the vacuum suction cup and the door and window to move into the box body 1, it will abut against the bottom plate 431 to make it move synchronously, so that the bottom plate 431 is always located at the lower end of the door and window after the door and window is attached to the inclined surface 111. When the first cylinder 41 pushes the baffle 42 downward, it can not only fix and seal the door and window, but also center and position and clamp the door and window, further improving the fixing effect.

[0059] During the automatic pushing and installing process of the door and window, although the mechanical pushing device significantly reduces the manpower requirement and improves the operation efficiency, the precise control of the mechanical pushing force is relatively difficult. When the door and window is pushed to the installation opening 11 and contacts the inclined surface 111, often due to excessive pushing force, the edge of the door and window is damaged by impact, which in turn affects the accuracy and reliability of the subsequent inspection and results in inaccurate inspection results.

[0060] A buffer assembly is also provided at the installation opening 11; the buffer assembly includes: a hinge plate 1121 sequentially hinged on the inclined surface 111 of the installation opening 11, a bladder 1122 fixedly installed on the inclined surface 111, and an auxiliary fixing assembly for assisting in fixing the fixed door and window after the bladder 1122 is compressed. The hinge plate 1121 and the inclined surface 111 are elastically connected by a spring 1124. The two sides of the installation opening 11 are inclined surfaces 111 that gradually approach from the outside to the inside, and the two inclined surfaces 111 are in a stepped shape.

[0061] The auxiliary fixing assembly includes: a push plate 1128 slidably installed on the pressing plate 434, an electric push rod 1127 driving the push plate to slide, and a control unit for controlling the telescopic distance of the electric push rod 1127; the control unit includes: a sensing member installed at the bottom of the bladder 1122, and a proximity switch fixedly installed on the hinge plate 1121; the proximity switch is electrically connected to the solenoid valve of the electric push rod 1127; the proximity switch on the hinge plate 1121 controls the telescopic distance of the electric push rod 1127 to gradually increase step by step along with the stepped inclined surface 111.

[0062] When the door and window are pushed to the inclined surface 111, the side frame of the door and window will first abut against the hinge plate 1121 on the inclined surface 111, causing the hinge plate 1121 to rotate along the pushing direction of the door and window and compressing the bladder 1122 behind the hinge plate 1121. This bladder 1122 serves as a buffer element, effectively absorbing and alleviating the impact generated during the pushing process of the door and window. When the hinge plate 1121 completely compresses the bladder 1122, it proves that the door and window are completely in contact with the inclined surface 111. At this time, the proximity switch contacts the sensing element, causing it to emit a sensing signal, controlling the electric push rod 1127 to extend and push the push plate 1128 to clamp and fix the side frame of the door and window that is in full contact with the inclined surface 111; further improving the fixing effect. At the same time, when the proximity switch contacts the sensing element, the proximity switch synchronously disconnects the power output of the power source to the vacuum suction cup, thereby reducing the impact damage to the edge of the door and window caused by excessive pushing force, which in turn affects the accuracy and reliability of subsequent inspections and results in inaccurate detection results.

[0063] It should be noted here that due to the different sizes of the door and window, when the electric push rod 1127 fixes the door and window by pushing the push plate 1128, it is necessary to preset the pushing stroke of the electric push rod 1127 in advance or rely on manual adjustment of its stroke. This step significantly increases the complexity of the operation process of the device and is difficult to achieve the integration and automation of the operation.

[0064] The proximity switch on the hinge plate 1121 controls the telescopic distance of the electric push rod 1127 to gradually increase as the stepped inclined surface 111 approaches. Thus, when the size of the door and window changes, the door and window to be detected will abut against different positions on the inclined surface 111 of the installation opening 11. At this time, the side frame of the door and window will squeeze the hinge plate 1121 at the corresponding position, and the proximity switch at the corresponding position will contact the sensing element. The electric push rod 1127 receives the electrical signal and pushes the push plate 1128 to move a set distance. For example: when the door and window are larger, the door and window will abut against the hinge rod at the installation opening 11 earlier. The electric push rod 1127 receives the electrical signal at this place and then pushes the push plate 1128 to push out a set distance, so that the push plate 1128 can just abut against the door and window, avoiding problems such as the door and window not being clamped or being damaged due to excessive clamping force caused by different pushing distances; thus, the abutting door and window can be accurately fixed, reducing the complexity of adjusting the stroke of the electric push rod 1127 due to different sizes of the door and window.

[0065] As a further expansion of this application: when the bladder 1122 is squeezed by the hinge plate 1121, the squeezed bladder 1122 will also drive the correction component to center and straighten the door and window to be detected, preventing the side frame of the door and window from not being able to abut well against the inclined surface 111 of the installation opening 11 due to its own skew when the door and window are pushed to the inclined surface 111 of the installation opening 11, which affects the installation efficiency.

[0066] The correction component includes: a push rod 1125 that pushes the articulated rod to flip, a sliding hole 1126 opened on the inclined surface 111, the push rod 1125 is slidably installed in the sliding hole 1126 through a seal, and the air outlet of the bladder 1122 communicates with the sliding hole 1126;

[0067] When the door and window are pushed to the inclined surface 111, the side frame of the door and window will first abut against the articulated plate 1121 on the inclined surface 111, causing the articulated plate 1121 to rotate along the pushing direction of the door and window, and compressing the bladder 1122 behind the articulated plate 1121. This bladder 1122 serves as a buffer element, effectively absorbing and alleviating the impact generated during the pushing process of the door and window.

[0068] At the same time, the bladder 1122 is squeezed, causing the gas in the bladder 1122 to flow into the sliding hole 1126. The push rod 1125 in the sliding hole 1126 extends towards the door and window under the push of the pressure, causing the articulated plate 1121 adjacent to the articulated plate 1121 to flip towards the door and window under the push of the push rod 1125. The articulated plate 1121 abuts against the door and window to be detected under the push of the push rod 1125, and preliminarily centers and corrects the door and window pushed to the installation opening, providing an early correction for the subsequent auxiliary fixing component to clamp the side frame of the door and window.

[0069] Moreover, when the articulated plate 1121 completely squeezes the bladder 1122, at this time, the air pressure in the bladder 1122 is completely injected into the sliding hole 1126, and the push rod 1125 receives the maximum thrust and firmly abuts against both sides of the door and window, performing a secondary locking on the installed door and window. Since during the physical detection of the door and window, the fixed door and window often needs to be tested for wind pressure resistance, airtightness, and watertightness, the door and window will shake to varying degrees during the detection. If not maintained, the mechanical connection of the fixing component may become loose due to continuous stress over time. By using the push rod 1125 to push the articulated plate 1121 to perform secondary locking on the door and window, it prevents the situation where the door and window detaches from the body and is damaged due to the loosening of the fixing component.

[0070] It should be noted here that the two inclined surfaces 111 are in a stepped shape, and the articulated plates 1121 are sequentially articulated on the trapezoidal inclined surface 111, so that when the size of the door and window changes, it can still abut well against the abutting plate. At the same time, when the detection is completed, the spring 1124 drives the articulated plate 1121 to reset.

[0071] The articulated plate 1121 is synchronously squeezed inward by the door and window to compress the bladder 1122. While slowing down the impact force of the door and window, the push rod 1125 pushes the adjacent articulated plate 1121 to assist in fixing the fixed door and window.

[0072] When testing doors and windows of different sizes, if the position of the fan 2 is kept fixed, it may not be possible to ensure uniform air flow scattering over the entire surface of the door and window due to the limited coverage of the fan 2. In this case, especially for larger-sized doors and windows, the air flow of the fan 2 may not effectively reach the far ends or corner areas of the door and window, thus affecting the accuracy of the test results.

[0073] The adjustment mechanism: synchronously adjusts the distance between the fan 2 and the door and window as the size of the door and window changes; the fan adjustment mechanism 5 includes: a distance adjustment component for adjusting the distance between the fan 2 and the door and window, and an angle adjustment component for adjusting the fan angle; the distance adjustment component includes: a fan frame 511, a first rack 512 fixedly connected to the positioning component 43, a first gear 513 meshing with the first rack 512, a second rack 514 meshing on the other side of the first gear 513, and the second rack 514 is fixedly connected to the fan frame 511;

[0074] When the power source pushes the vacuum suction cup and the door and window to be tested to move inside the box body 1, it will synchronously push the bottom plate 431 to move towards the inside of the box body 1. At this time, the first rack 512 fixedly connected to the bottom plate 431 drives the first gear 513 to rotate, and the second rack 514 moves in the opposite direction accordingly. Thus, when the bottom plate 431 moves inward with the door and window, the fan frame 511 moves towards the door and window; so when the door and window is larger, the door and window will come into contact with the installation bevel earlier, so that the moving distance of the first rack 512 is short, and the relative distance from the fan frame 511 to the door and window is also reduced accordingly, and vice versa the stroke increases; thus, the distance between the door and window and the fan 2 can be well controlled, improving the test accuracy.

[0075] It should be noted here that by setting the installation opening 11 into a trapezoidal structure, when installing doors and windows of different sizes, due to the inherent geometric characteristics of the trapezoid, larger-sized doors and windows will come into contact with the inclined surface 111 of the installation opening 11 earlier, while smaller-sized doors and windows need to be pushed deeper to fit the inclined surface 111. This design enables the distance between the door and window and the fan 2 to be automatically adjusted according to the difference in the size of the door and window on the premise that the position of the fan 2 remains fixed, thereby broadening the effective coverage range of the fan 2, significantly improving the test accuracy, and also greatly reducing the necessary time for manual secondary position adjustment, improving the operation efficiency; therefore, even without using the above structure, the distance of the fan 2 can still be adjusted, and through the above structure, this adjustment effect can be significantly enhanced, achieving a more optimized performance.

[0076] Synchronize with the moving distance of the door and window inside the box body 1 to control the distance between the fan 2 and the door and window.

[0077] When the heights of the doors and windows are different, if the angle of the fan 2 is not adjusted, it will still cause the problem of dead corners;

[0078] The angle adjustment component includes: a third rack 521 slidably connected to the baffle 42, the fan 2 is hinged to the fan frame 511 through a rotating shaft, a second gear 522 fixedly installed on the rotating shaft, and the second gear 522 meshes with the third rack 521;

[0079] When the first cylinder 41 pushes the baffle 42 to press down and block the doors and windows, the third rack 521 will be pressed down synchronously. The rack drives the second gear 522 to rotate, and then drives the fan 2 hinged to the fan frame 511 to rotate. The third rack 521 is slidably installed on the baffle 42. When the motor frame moves under the push of the bottom plate 431, the third rack 521 can slide on the baffle 42, thus preventing movement interference. Therefore, when the height of the doors and windows is relatively high, the distance that the first cylinder 41 pushes the baffle 42 to move becomes smaller, the distance that drives the third rack 521 to move becomes shorter, and the rotation amplitude of the second gear 522 becomes smaller. Thus, the angle of the fan 2 can be well controlled, and the angle of the fan 2 always matches the size of the doors and windows, avoiding problems with detection accuracy caused by dead corners in the far end or corner areas of the doors and windows.

[0080] It should be summarized here that when the first cylinder 41 pushes downward, on the one hand, it pushes the baffle 42 to fix the doors and windows and synchronously pushes the doors and windows to be centered, and on the other hand, when the baffle 42 moves downward, it pushes the third rack 521 to adjust the angle of the fan 2 on the fan frame 511, preventing the problem that the wind blown by the fan 2 causes dead corners on the surface of the doors and windows and affecting the detection effect.
