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.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 10 As shown, a device for detecting physical properties of doors and windows of the present invention comprises: a box body 1, a fan 2, a pushing mechanism 3, a fixing mechanism 4, and a fan adjusting mechanism 5; The box body 1 is provided with an installation opening 11; the pushing mechanism 3 is used to transport the doors and windows to be inspected into the box body 1; the pushing mechanism 3 includes: a buckle box 31, a clamping assembly for pushing the buckle box 31 to engage with the box body 1, a door and window suction piece 33 slidably connected to the buckle box 31, and a power source for pushing the suction piece 33 to abut the doors and windows against the installation opening 11; the clamping assembly includes: a cylinder 2 321 fixedly installed on the box body 1, and the telescopic rod of the cylinder 2 321 is fixedly connected to the buckle box 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.

[0024] When it is necessary to transport the doors and windows, they only need to be manually moved into the buckle box 31, and the vacuum suction cups in the buckle box 31 will suck the doors and windows to be inspected. When the doors and windows need to be fixed on the installation port 11 of the box body 1, the cylinder 2 321 is reset, and drives the buckle box 31 to approach the box body 1 synchronously, so that the buckle box 31 is engaged with the box body 1, thereby ensuring that the doors and windows to be inspected are in a stable state without external interference, thereby improving the accuracy and efficiency of the entire inspection process; when the buckle 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 port 11 to the box body 1, and when 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 when the doors and windows are inspected.

[0025] It should be noted here that since the two sides of the installation opening 11 are inclined surfaces 111 that gradually approach each other from the outside to the inside, when the sizes of doors and windows are different, the doors and windows to be inspected are pushed by the power source and the distances between the two inclined surfaces 111 of the installation opening 11 are different. At the same time, the two inclined surfaces 111 can adapt to doors and windows of different sizes, which enhances the versatility of the installation opening 11 and enables it to adapt to doors and windows of various specifications, thereby significantly improving the flexibility and adaptability during the installation and inspection of doors and windows.

[0026] Moreover, both sides of the installation opening 11 are formed into inclined surfaces 111 which gradually approach each other from the outside to the inside. When the airflow generated by the fan 2 is guided along the inclined surface 111, the wind can be more concentrated on the window surface, which not only improves the accuracy of the test and ensures the accuracy and reliability of simulating the actual wind pressure environment, but also optimizes the test efficiency and shortens the test cycle by reducing the required air volume. At the same time, this design enhances the safety of the test and makes the pressure distribution of the doors and windows during the test more uniform, reducing the risk of damage. In addition, the design of the inclined surface 111 also ensures that doors and windows of different sizes obtain similar wind flow conditions during the test, thereby improving the consistency and comparability of the test results.

[0027] The fixing mechanism 4: transports the doors and windows of different sizes into the box body 1 and automatically fixes them; the fixing mechanism 4 includes: a cylinder 1 41 fixedly connected to the top of the box body 1, a baffle 42 slidably installed at the installation port 11, and a positioning component 43 for positioning the doors and windows when the baffle 42 presses down the doors and windows; the piston rod of the cylinder 1 41 is fixedly connected to the baffle 42, and the positioning component 43 is slidably installed at the bottom of the box body 1; start the cylinder 2 321, so that the baffle 42 presses the doors and windows downward, and drives the positioning component 43 to center the doors and windows.

[0028] When the door and window to be inspected are pushed to the installation opening 11 of the box body 1 and fit with the inclined surface 111, the cylinder 41 pushes the baffle 42 downward, so that the baffle 42 is engaged on the upper end surface of the door and window, completing the preliminary fixation of the door and window up and down and left and right; 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, so that when the cylinder 41 pushes the baffle 42 to move downward, the baffle 42 and the inclined surface 111 of the installation opening 11 can achieve a good sealing effect.

[0029] The positioning assembly 43 includes: a bottom plate 431, a trapezoidal groove 432 provided on the bottom plate 431, a clamping plate 433 slidably mounted on the bottom surface of the trapezoidal groove 432, a pressure plate 434 elastically mounted in the trapezoidal groove 432, and a pressure piece 435 that drives the clamping plate 433 to move toward each other as the pressure plate 434 moves downward; the pressure piece 435 is composed of a fixed portion 4352, a sliding portion 4351, and a return spring 436 that drives the sliding portion 4351 to return to its original position; the mounting portion of the pressure piece 435 is fixedly connected to the pressure plate 434; the sliding portion 4351 of the pressure piece 435 abuts against the inclined surface 111 of the trapezoidal groove 432, and the sliding portion 4351 of the pressure piece 435 also abuts against the clamping plate 433; the door and window press down the pressure plate 434, and the clamping plate 433 clamps the door and window on the pressure plate 434 in the center under the push of the pressure piece 435.

[0030] When the cylinder 41 pushes the baffle plate 42 to move downward, it will press down the door and window. The pressed door and window will compress the pressure plate 434 in the bottom plate 431, so that the pressure plate 434 moves downward in the trapezoidal groove 432 of the bottom plate 431, and the pressure-receiving member 435 moves downward with the pressure plate 434. At this time, the sliding portion 4351 of the pressure-receiving member 435 gradually retracts into the mounting portion of the pressure-receiving member 435 under the abutment of the trapezoidal groove 432. Because the sliding portion 4351 of the pressure-receiving member 435 is also abutted against the clamping plate 433, when the pressure-receiving member 435 is squeezed and retracted inward by the trapezoidal groove 432, the clamping plate 433 is synchronously driven to slide toward each other at the bottom of the trapezoidal groove 432 until it abuts against the door and window on the pressure plate 434, The window is clamped and fixed in the center; thereby preventing the potential risk of damage caused by unstable or tilted door and window fixation during the subsequent wind pressure test of the door and window, and ensuring the accuracy and reliability of the test results; finally, after the door and window are tested, the pressure plate 434 elastically installed in the trapezoidal groove 432 drives the door and window to pop out of the trapezoidal groove 432 for the convenience of subsequent loading and unloading of the tested door and window, and at the same time, when the pressure plate 434 is reset, it drives the pressure-bearing piece 435 to move upward, and the sliding portion 4351 of the pressure-bearing piece 435 ends the constraint on the inclined surface 111 of the trapezoidal groove 432, and the reset spring 436 drives the sliding portion 4351 of the pressure-bearing piece 435 to reset, and at the same time, the sliding portion 4351 of the pressure-bearing piece 435 drives the clamping plate 433 to reset.

[0031] It should be added here that after the buckle box 31 is engaged with the box body 1, the power source pushes the vacuum suction cup and the doors and windows into the box body 1, and at the same time, it abuts against the bottom plate 431 to make them move synchronously, so that the bottom plate 431 is always located at the lower end of the doors and windows after the doors and windows are in contact with the inclined surface 111. When the cylinder 41 pushes the baffle 42 to move downward, it can not only fix and seal the doors and windows, but also center the doors and windows, thereby further improving the fixing effect.

[0032] In the process of automatically pushing and installing doors and windows, although the use of a mechanical pushing device significantly reduces the manpower requirements and improves work efficiency, it is difficult to accurately control the mechanical pushing force. When the doors and windows are pushed to the installation port 11 and contact the inclined surface 111, the pushing force is often too large, causing the edges of the doors and windows to suffer impact damage, thereby affecting the accuracy and reliability of subsequent inspections and causing inaccurate detection results.

[0033] The installation opening 11 is also provided with a buffer assembly, which includes: a hinge plate 1121 hinged on the inclined surface 111 of the installation opening 11 in sequence, a capsule 1122 fixedly mounted on the inclined surface 111, and an auxiliary fixing assembly for auxiliary fixing of the fixed door and window after the capsule 1122 is compressed, and the hinge plate 1121 is elastically connected to the inclined surface 111 through a spring 1124. The two sides of the installation opening 11 are gradually approaching inclined surfaces 111 from the outside to the inside, and the two inclined surfaces 111 are stepped.

[0034] The auxiliary fixing assembly includes: a push plate 1128 slidably mounted on the pressure plate 434, an electric push rod 1127 that drives the sliding movement, and a control unit that controls the telescopic distance of the electric push rod 1127; the control unit includes: a sensing element mounted at the bottom of the capsule 1122, and a proximity switch fixedly mounted on the hinged plate 1121; the proximity switch is electrically connected to the solenoid valve of the electric push rod 1127; the proximity switch on the hinged plate 1121 controls the telescopic distance of the electric push rod 1127 to increase step by step along the stepped inclined surface 111.

[0035] When the door and window are pushed to the inclined surface 111, the side frame of the door and window will first abut the hinge plate 1121 on the inclined surface 111, so that the hinge plate 1121 rotates in the pushing direction of the door and window, and compresses the capsule 1122 behind the hinge plate 1121. The capsule 1122 acts as a buffer element to effectively absorb and alleviate the impact generated during the pushing process of the door and window. When the hinge plate 1121 completely compresses the capsule 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 send a sensing signal, controlling the electric push rod 1127 to extend and push the push plate 1128 to clamp and fix the door and window side frame that is completely in 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, thereby affecting the accuracy and reliability of subsequent inspections, and causing inaccurate detection results.

[0036] It should be noted here that due to the different sizes of doors and windows, when the electric push rod 1127 pushes the push plate 1128 to fix the doors and windows, the pushing stroke of the electric push rod 1127 needs to be set in advance, or rely on manual control of its stroke. This step significantly increases the complexity of the operating process of the device, making it difficult to achieve integrated and automated operations.

[0037] The proximity switch on the hinged plate 1121 controls the extension and retraction distance of the electric push rod 1127 to increase step by step as the stepped inclined surface 111 approaches. Therefore, when the size of the door and window changes, the door and window to be detected will abut against different positions of the inclined surface 111 of the installation opening 11. At this time, the side frame of the door and window will squeeze the hinged 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 large, the door and window will abut against the hinged rod at the installation opening 11 earlier. The electric push rod 1127 receives the electrical signal therefrom and pushes the push plate 1128 out a set distance, so that the push plate 1128 can just abut against the door and window, and there will be no problem of damage to the door and window due to the different pushing distances. Therefore, the abutted door and window can be accurately fixed, reducing the cumbersomeness of adjusting the stroke of the electric push rod 1127 due to the different sizes of the door and window.

[0038] As a further extension of the present application: when the sac 1122 is squeezed by the hinged plate 1121, the squeezed sac 1122 will also drive the correction component to center the door and window to be inspected, to prevent the door and window from being pushed to the inclined surface 111 of the installation port 11, where the side frames of the door and window cannot be well abutted against the inclined surface 111 of the installation port 11 due to their own skewness, thereby affecting the installation efficiency.

[0039] The correction assembly includes: a push rod 1125 for pushing the hinge rod to flip, a sliding hole 1126 provided on the inclined surface 111, the push rod 1125 is slidably installed in the sliding hole 1126 through a sealing member, and the air outlet of the capsule 1122 is connected to the sliding hole 1126; When the door or window is pushed to the inclined surface 111, the side frame of the door or window will first abut against the hinge plate 1121 on the inclined surface 111, so that the hinge plate 1121 rotates along the pushing direction of the door or window and compresses the capsule 1122 behind the hinge plate 1121. The capsule 1122 acts as a buffer element to effectively absorb and alleviate the impact generated during the pushing process of the door or window. At the same time, the capsule 1122 is squeezed, so that the gas in the capsule 1122 passes into the sliding hole 1126, and the push rod 1125 in the sliding hole 1126 extends toward the door and window under the pressure, so that the hinge plate 1121 adjacent to the hinge plate 1121 is flipped toward the door and window under the push of the push rod 1125, and the hinge plate 1121 abuts against the door and window to be inspected under the push of the push rod 1125, and the door and window pushed to the installation port are initially centered and corrected in advance when the subsequent auxiliary fixing assembly clamps the door and window side frames; Furthermore, when the hinged plate 1121 completely squeezes the bag 1122, the air pressure in the bag 1122 is completely injected into the sliding hole 1126, and the push rod 1125 is subjected to the maximum thrust, firmly abutting against the two sides of the doors and windows, thereby performing a secondary locking on the installed doors and windows. During the physical inspection of the doors and windows, the fixed doors and windows often need to be tested for wind pressure resistance, air tightness, and water tightness. Therefore, during the inspection of the doors and windows, they will be subjected to different degrees of shaking. If they are not maintained for a long time, the mechanically connected fixing components may become loose due to continuous force. The push rod 1125 pushes the hinged plate 1121 to perform a secondary locking on the doors and windows to prevent the fixing components from loosening and causing the doors and windows to detach from the body and be damaged.

[0040] It should be noted here that the two inclined surfaces 111 are stepped, and the hinged plates 1121 are hinged on the trapezoidal inclined surfaces 111 in sequence, so that when the size of the door or window changes, it can still abut against the abutment plate well. At the same time, when the detection is completed, the spring 1124 drives the hinged plate 1121 to reset.

[0041] The hinged plates 1121 are squeezed by the doors and windows and simultaneously squeeze the bladder 1122 inwards, which reduces the impact force of the doors and windows while the push rod 1125 pushes the adjacent hinged plates 1121 to assist in fixing the fixed doors and windows.

[0042] When testing doors and windows of different sizes, if the position of fan 2 is kept fixed, it may not be possible to ensure that the airflow is evenly scattered over the entire surface of the door and window due to the limited coverage of fan 2; in this case, especially for doors and windows of larger sizes, the airflow of fan 2 may not be able to effectively reach the far ends or corners of the doors and windows, thereby affecting the accuracy of the test results.

[0043] The adjustment mechanism: when the size of the door and window changes, the distance between the fan 2 and the door and window is synchronously adjusted; 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 rack 1 512 fixedly connected to the positioning component 43, a gear 1 513 meshing with the rack 1 512, a rack 2 514 meshing with the other side of the gear 1 513, and the rack 2 514 is fixedly connected to the fan frame 511; When the power source pushes the vacuum suction cup and the door and window to be tested to move in the box body 1, the bottom plate 431 will be pushed to move toward the inside of the box body 1 synchronously. At this time, the rack 1 512 fixedly connected to the bottom plate 431 drives the gear 1 513 to rotate, and the rack 2 514 moves in the opposite direction accordingly. Therefore, when the bottom plate 431 moves inward with the door and window, the fan frame 511 moves toward the door and window. Therefore, when the door and window are large, the door and window will contact the installation bevel earlier, so that the moving distance of the rack 1 512 is short, and the relative distance from the fan frame 511 to the door and window is also reduced, otherwise the stroke is increased. Therefore, the distance from the door and window to the fan 2 can be well controlled, thereby improving the detection accuracy.

[0044] It should be noted here that by setting the installation opening 11 into a trapezoidal structure, when installing doors and windows of different sizes, thanks to the inherent geometric characteristics of the trapezoid, large-sized doors and windows will come into contact with the inclined surface 111 of the installation opening 11 earlier, while small-sized doors and windows need to be pushed deeper to fit the inclined surface 111. This design allows the distance from the doors and windows to the fan 2 to be automatically adjusted according to the difference in the size of the doors and windows while the position of the fan 2 remains fixed, thereby widening the effective coverage of the fan 2, significantly improving the detection accuracy, and greatly reducing the time required for manual secondary position adjustment, thereby improving work efficiency; therefore, the problem of adjusting the distance of the fan 2 can still be solved without using the above structure, and the above structure can significantly enhance this adjustment effect and achieve more optimized performance.

[0045] The distance between the fan 2 and the door and window is controlled synchronously with the distance the door and window move in the box 1.

[0046] When the heights of doors and windows are different, if the angle of fan 2 is not adjusted, the problem of blind spots will still occur; The angle adjustment assembly includes: a rack 3 521 slidably connected to the baffle 42, the fan 2 is hinged to the fan frame 511 through a rotating shaft, and a gear 2 522 is fixedly mounted on the rotating shaft, and the gear 2 522 is meshed with the rack 3 521; When the cylinder 1 41 pushes the baffle 42 to press down and cover the door and window, the rack 3 521 is pressed down synchronously, and the rack drives the gear 2 522 to rotate, thereby driving the fan 2 hinged on the fan frame 511 to rotate, and the rack 3 521 is slidably installed on the baffle 42. When the motor frame moves under the push of the base plate 431, the rack 3 521 can slide on the baffle 42, so as not to cause motion interference; therefore, when the height of the door and window is high, the distance that the cylinder 1 41 pushes the baffle 42 to move becomes smaller, and the distance that the rack 3 521 drives to move becomes shorter, and the rotation amplitude of the gear 2 522 becomes smaller, so that the angle of the fan 2 can be well controlled. The angle of the fan 2 always matches the size of the door and window, and the dead angle in the far end or corner area of ​​the door and window causes problems with detection accuracy.

[0047] It should be summarized here that when the cylinder 41 is pushed downward, on the one hand, it pushes the baffle 42 to fix the doors and windows, and simultaneously pushes the doors and windows to center the doors and windows; on the other hand, when the baffle 42 moves downward, it pushes the rack 3 521 to adjust the angle of the fan 2 on the fan frame 511 to prevent the wind blown by the fan 2 from forming a dead angle on the surface of the doors and windows, thereby affecting the detection effect.
