Description

Technical Field

[0001] This utility model relates to the field of door and window production equipment, specifically to a performance testing device for the production and processing of thermally broken aluminum doors and windows. Background Technology

[0002] Thermally broken aluminum windows and doors are made of thermally broken aluminum profiles and insulated glass. They have multiple functions such as energy saving, sound insulation, noise reduction, dust prevention, and waterproofing, and are a widely used type of window and door in modern buildings.

[0003] Thermally broken aluminum windows and doors divide the originally continuous aluminum profile into inner and outer parts by embedding a thermal break strip, forming a "heat conduction blocking layer." This design significantly reduces the efficiency of heat transfer through the profile, making its thermal conductivity 40%-70% lower than that of ordinary aluminum windows and doors, effectively blocking heat transfer and achieving a warm winter and cool summer effect. However, it is inconvenient to test the thermal insulation performance of thermally broken aluminum windows and doors during the production process, making it impossible to ensure that the product meets design expectations and functional requirements. Furthermore, untested windows and doors may have hidden defects, leading to problems during use, increasing after-sales costs and brand risk. Utility Model Content

[0004] To address the technical problems of the inconvenience of testing the thermal insulation performance of thermally broken aluminum windows and doors during the existing production process, which makes it impossible to ensure that the products meet the design expectations and functional requirements, and the potential for hidden defects in untested windows and doors, leading to problems during use, increased after-sales costs and brand risks, this utility model provides a performance testing device for the production and processing of thermally broken aluminum windows and doors.

[0005] The technical solution adopted by this utility model is as follows: it includes a test box, a fixed frame is provided on one side of the test box, and a placement slot is opened on the opposite side of the test box and the fixed frame. A thermally broken aluminum door or window is placed in the placement slot. A heating lamp is fixedly installed on the inner top wall of the test box. A first mounting plate is fixedly connected to the test box. A first thermometer and a first temperature measuring gun are fixedly installed on the first mounting plate. A second mounting plate is fixedly connected to one side of the fixed frame. A second thermometer and a second temperature measuring gun are fixedly installed on the second mounting plate. A display screen is fixedly installed on the outside of the test box.

[0006] Furthermore, mounting bases are fixedly installed on both sides of the test box, and connecting plates are rotatably installed on each mounting base. A fixing plate is fixedly connected to one side of the connecting plate, and a pressure block is slidably connected in the fixing plate. A screw is rotatably installed on the fixing plate, and one end of the screw is rotatably mounted on the pressure block.

[0007] By adopting the above technical solution, the thermally broken aluminum doors and windows are fixed between the test box and the fixed frame.

[0008] Furthermore, sealing gaskets are fixedly installed on the side walls of both sets of placement slots.

[0009] By adopting the above technical solutions, the sealing performance between thermally broken aluminum doors and windows and the test box and fixed frame is improved.

[0010] Furthermore, a limiting groove is formed on the side wall of the fixing plate, and a limiting block is slidably connected in the limiting groove. The limiting block is fixedly installed at one end of the pressure block.

[0011] By adopting the above technical solution, the stability of the fixed plate during movement is improved.

[0012] Furthermore, the pressure block is provided with an anti-detachment groove, and one end of the screw is fixedly connected to an anti-detachment head, which is rotatably installed in the anti-detachment groove.

[0013] By adopting the above technical solution, the stability of the screw rotation mounted on the pressure block is improved.

[0014] Furthermore, a sliding groove is provided in the side wall of the test box, a sliding plate is fixedly installed on one side of the fixed frame, the sliding plate is slidably connected in the sliding groove, and an anti-detachment block is fixedly connected to one side of the sliding plate.

[0015] By adopting the above technical solution, it is easier to install and remove thermally broken aluminum doors and windows during the testing process.

[0016] The beneficial effects of this utility model are as follows: A test chamber, along with a fixed frame, sealing gasket, heating lamp, first thermometer, first temperature gun, second thermometer, second temperature gun, and display screen, is used. The heating lamp makes the internal temperature of the test chamber higher than the external environment. The measured temperature is displayed on the display screen. By comparing the temperature difference between the inside of the test chamber and the external environment, and the temperature difference between the glass surfaces on both sides of the thermally broken aluminum window, the thermal insulation performance of the thermally broken aluminum window is evaluated using the temperature difference. The larger the temperature difference, the better the thermal insulation performance of the thermally broken aluminum window. This allows for the determination of whether the produced thermally broken aluminum window meets the design expectations and functional requirements. Window that does not meet these requirements indicates hidden defects, which can be inspected and repaired to meet the requirements. This reduces the occurrence of problems during the use of the produced thermally broken aluminum window, thereby reducing after-sales costs and brand risks.

[0017] The mounting base, along with the connecting plate, fixing plate, pressure block, and screw, allows the screw to rotate, causing the pressure block to move. The pressure block then pushes the fixing frame towards the test box, ensuring that the thermally broken aluminum window is stably fixed between the test box and the fixing frame. Since the two sides of the thermally broken aluminum window are in different environments, the pressure block, along with the limiting groove and limiting block, and the screw, along with the anti-disengagement groove and anti-disengagement head, improves the stability of the pressure block during movement.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be further described below.

[0028] To address the problems existing in the background technology, this application proposes the following technical solution: A test chamber 1 is included, with a fixed frame 2 on one side of the test chamber 1. Placement slots 3 are provided on opposite sides of both the test chamber 1 and the fixed frame 2, and aluminum alloy doors / windows 4 are placed in the placement slots 3. A heating lamp 5 is fixedly installed on the inner top wall of the test chamber 1. A first mounting plate 6 is fixedly connected inside the test chamber 1, and a first thermometer 7 and a first temperature measuring gun 8 are fixedly installed on the first mounting plate 6. A second mounting plate 9 is fixedly connected to one side of the fixed frame 2, and a second thermometer 10 and a second temperature measuring gun 11 are fixedly installed on the second mounting plate 9. A display screen 12 is fixedly installed on the outside of the test chamber 1.

[0029] Remove the fixing frame 2 from one side of the test chamber 1, place the manufactured thermally broken aluminum window 4 into the placement slot 3, move the fixing frame 2 back to one side of the test chamber 1, and clamp the thermally broken aluminum window 4 between the test chamber 1 and the fixing frame 2. The thermally broken aluminum window 4 separates the inside of the test chamber 1 from the external environment. Connect the heating lamp 5 to the external power supply. The heating lamp 5 works to raise the temperature inside the test chamber 1, making the internal temperature of the test chamber 1 higher than the external environment. After a period of time, the first thermometer 7 measures the internal temperature of the test chamber 1, the first temperature gun 8 measures the temperature of the glass of the thermally broken aluminum window 4 near the test chamber 1, the second thermometer 10 measures the external ambient temperature, and the second temperature gun 11 measures the temperature of the glass of the thermally broken aluminum window 4 near the fixing frame 2. The measured temperature... The temperature is displayed on the screen 12. By comparing the temperatures measured by the first thermometer 7 and the second thermometer 10, the greater the temperature difference between the two, the better the thermal insulation performance of the thermally broken aluminum window 4. By comparing the temperatures measured by the first temperature gun 8 and the second temperature gun 11, the thermal insulation performance of the thermally broken aluminum window 4 can be evaluated. The data on the screen 12 is used to determine whether the produced thermally broken aluminum window 4 meets the design expectations and functional requirements. If the thermally broken aluminum window 4 does not meet the requirements, it indicates that there are hidden defects. By inspecting and repairing it to meet the requirements, the occurrence of problems during the use of the produced thermally broken aluminum window 4 can be reduced, thereby reducing after-sales costs and brand risks. The first thermometer 7 and the second thermometer 10 are PEAKMETER PM6508 thermometers, and the first temperature gun 8 and the second temperature gun 11 are Fluke MT4 MAX+ temperature guns.

[0030] To further explain, mounting bases 14 are fixedly installed on both sides of the test box 1, and connecting plates 15 are rotatably installed on the mounting bases 14. A fixing plate 16 is fixedly connected to one side of the connecting plate 15, and a pressure block 17 is slidably connected in the fixing plate 16. A screw 18 is rotatably installed on the fixing plate 16, and one end of the screw 18 is rotatably set on the pressure block 17.

[0031] After the thermally broken aluminum window 4 is placed in the placement slot 3 and the fixed frame 2 is moved to one side of the test box 1, the connecting plate 15 is rotated so that the fixed plate 16 rotates to one side of the fixed frame 2. The screw 18 is rotated, and the screw 18 pushes the pressure block 17 to move towards the fixed frame 2. The pressure block 17 contacts and squeezes one side of the fixed frame 2, pushing the fixed frame 2 closer to the test box 1, thereby firmly clamping the thermally broken aluminum window 4 between the test box 1 and the fixed frame 2, improving the stability of the thermally broken aluminum window 4 during the test.

[0032] Furthermore, sealing gaskets 13 are fixedly installed on the side walls of both sets of placement slots 3.

[0033] The sealing gasket 13 is made of a heat-insulating elastic material, such as PA66 nylon thermal insulation strip with a thermal conductivity of only 0.28 W / (m·K). When the thermally broken aluminum window 4 is clamped and fixed between the test box 1 and the fixed frame 2, the two sides of the thermally broken aluminum window 4 squeeze the sealing gasket 13 to deform it. The elasticity of the sealing gasket 13 improves the sealing performance between the thermally broken aluminum window 4 and the placement groove 3, preventing the temperature inside the test box 1 from escaping from the gap between the thermally broken aluminum window 4 and the placement groove 3, thereby improving the accuracy of the thermal insulation performance test results of the thermally broken aluminum window 4.

[0034] To further explain, a limiting groove 19 is provided on the side wall of the fixing plate 16, and a limiting block 20 is slidably connected in the limiting groove 19. The limiting block 20 is fixedly installed at one end of the pressure block 17.

[0035] The limiting block 20, together with the limiting groove 19, guides and limits the movement of the pressure block 17, preventing the pressure block 17 from flipping over when the screw 18 rotates, thus improving the stability of the pressure block 17 during movement and ensuring that the thermally broken aluminum window 4 is stably fixed between the test box 1 and the fixed frame 2.

[0036] Furthermore, the pressure block 17 is provided with an anti-detachment groove 21, and one end of the screw 18 is fixedly connected to an anti-detachment head 22, which is rotatably installed in the anti-detachment groove 21.

[0037] The anti-detachment head 22 enables one end of the screw 18 to be stably rotated and mounted on the pressure block 17, further improving the stability of the pressure block 17 when it moves.

[0038] Furthermore, a groove 23 is provided in the side wall of the test box 1, and a slide plate 24 is fixedly installed on one side of the fixed frame 2. The slide plate 24 is slidably connected in the groove 23, and an anti-detachment block 25 is fixedly connected to one side of the slide plate 24.

[0039] The sliding plate 24, together with the sliding groove 23, guides the movement of the fixed frame 2, so that the fixed frame 2 moves smoothly on one side of the test box 1. The anti-detachment block 25 restricts the range of movement of the fixed frame 2, preventing the sliding plate 24 from accidentally sliding out of the sliding groove 23 and improving the convenience of moving the fixed frame 2.

[0040] The specific operation is as follows: Rotate the fixing plate 16 away from one side of the fixing frame 2, pull the fixing frame 2 away from one side of the test chamber 1, place the manufactured thermally broken aluminum window 4 in the placement slot 3, move the fixing frame 2 back to one side of the test chamber 1, then rotate the fixing plate 16 back to one side of the fixing frame 2, rotate the screw 18, the screw 18 pushes the pressure block 17 towards the fixing frame 2, the pressure block 17 pushes the fixing frame 2 closer to the test chamber 1, thus firmly clamping the thermally broken aluminum window 4 between the test chamber 1 and the fixing frame 2. The heating lamp 5 works to raise the temperature inside the test chamber 1, making the internal temperature of the test chamber 1 greater than the external temperature. After a period of time, the first thermometer 7 measures the internal temperature of the test chamber 1, the first temperature gun 8 measures the temperature of the glass on the thermally broken aluminum window 4 near the test chamber 1, the second thermometer 10 measures the external ambient temperature, and the second temperature gun 11 measures the temperature of the glass on the thermally broken aluminum window 4 near the fixed frame 2. The measured temperatures are displayed on the display screen 12. By comparing the temperature difference between the inside of the test chamber 1 and the external environment, and the temperature difference between the glass surfaces on both sides of the thermally broken aluminum window 4, the thermal insulation performance of the thermally broken aluminum window 4 is evaluated through the temperature difference. The larger the temperature difference, the better the thermal insulation performance of the thermally broken aluminum window 4.
