Description

Technical Field

[0001] This utility model relates to the technical field of door and window insulation testing equipment, and in particular to a device for testing the thermal insulation performance of building doors and windows. Background Technology

[0002] The thermal insulation performance testing of building doors and windows is based on the principle of steady-state heat transfer. A calibrated heat chamber is used to test the thermal insulation performance of windows. One side of the specimen is a heat chamber to simulate the indoor climate conditions of a heated building in winter, and the other side is a cold chamber to simulate the outdoor climate conditions in winter. The gaps in the test specimen are sealed. Under the condition that the air temperature, gas flow rate and heat radiation are kept stable on both sides, the heat output of the electric heater in the heat chamber is tested. The heat loss through the outer wall of the heat chamber and the specimen frame is subtracted, and the result is divided by the product of the specimen area and the temperature difference between the two sides of the air to obtain the heat transfer coefficient of the specimen.

[0003] According to the announcement number CN218782226U, a testing tool for the thermal insulation performance of building doors and windows is proposed. By setting a cold box below the fixed frame and a hot box above the fixed frame, and setting a clamping column inside the hot box, the door and window to be tested can be clamped without the need for clamps in actual use. The clamping column can clamp door and window of different specifications, thus optimizing the versatility of the testing tool for the thermal insulation performance of building doors and windows.

[0004] In the process of testing the thermal insulation performance of building doors and windows, clamps are an important tool to ensure the fixation of doors and windows, the accuracy of testing, and stability. However, clamps are usually designed with fixed specifications, that is, the opening size of the clamp is fixed and cannot be adjusted according to different specifications of doors and windows. This means that clamps with fixed specifications may not fit tightly against the edges of doors and windows, affecting the accuracy of test results.

[0005] Therefore, there is an urgent need to provide a testing device for the thermal insulation performance of building doors and windows to solve the above problems. Utility Model Content

[0013] The above technical solution involves installing a motor to drive the ball screw to rotate, which in turn drives the two mating sliders to move to opposite sides.

[0014] The present invention is further configured such that the top end of the docking slider on one side is fixedly connected to the hot box, and the top end of the docking slider on the other side is fixedly connected to the cold box.

[0015] With the above technical solution, the docking slider on one side drives the hot box to move along the first guide rail, and the docking slider on the other side drives the cold box to move along the second guide rail.

[0021] Through the above technical solution, the third insulation board of different specifications is installed by adjusting the plate of the second cylinder. The second cylinder drives the third insulation board to move, and the third insulation board moves stably on the insulation board guide rail through the insulation board rail.

The bottom end of the outer shell 1 is provided with a docking mechanism 8 for clamping the assembled thermal insulation board structure. The docking mechanism 8 includes a mounting motor 801 fixed to one end of the outer shell 1. The output shaft of the mounting motor 801 is fixedly connected to a ball screw 802 through a coupling. Two docking sliders 803 with ball nut seats are installed on the external threads of the ball screw 802. The top of one docking slider 803 is fixedly connected to the hot box 3, and the top of the other docking slider 803 is fixed to the cold box 5. The inner bottom wall of the outer casing 1 is fixed with an installation strip 804. The top of the installation strip 804 is fixed with a first insulation board 805 by bolts. The inner top and inner bottom walls of the outer casing 1 are both fixed with two insulation board guide rails 806. Different temperature conditions are set in the hot box 3 and the cold box 5 to simulate the hot and cold environment of the door and window in actual use. The hot box 3 and the cold box 5 are opened and closed by the opening and closing door 6, and then the door and window are moved in. The installation motor 801 drives the ball screw 802 to rotate. The ball screw 802 drives the two docking sliders 803 to move to the opposite side. The docking slider 803 on one side drives the hot box 3 to move along the first guide rail 2. The docking slider 803 on the other side drives the cold box 5 to move along the second guide rail 4, thereby clamping the insulation board. The space between the hot box 3, the cold box 5 and the insulation board is filled with insulation foam. The first insulation board 805 of different specifications is installed by the installation strip 804.

The adjustment plate of the second cylinder 903 is used to install third insulation boards 904 of different specifications. The second cylinder 903 drives the third insulation board 904 to move. The third insulation board 904 moves stably on the insulation board guide rail 806 by the insulation board rail 905. The third insulation board 904 is installed on both sides of the door and window body 906 by insulation foam, so that the door and window body 906 is fixed to the insulation board by insulation foam on all four sides to prevent air leakage.

[0035] In use, this utility model opens and closes the hot box 3 and cold box 5 via the opening and closing door 6, allowing the door / window body 906 to be moved inside. The door / window body 906 is then fixed to the top of the first insulation board 805 using insulation foam. Different specifications of second insulation boards 902 are installed using the adjusting plate of the first cylinder 901, which raises and lowers the second insulation board 902, connecting it to the top of the door / window body 906 via insulation foam. Different specifications of third insulation boards 904 are installed using the adjusting plate of the second cylinder 903, which moves the third insulation board 904. The third insulation board 904 moves stably on the insulation board guide rail 806 via the insulation board track 905, and is connected to the door / window body via insulation foam. The insulation board is installed on both sides of the door / window body 906, so that the insulation foam is fixed to the insulation board on all four sides to prevent air leakage. The motor 801 drives the ball screw 802 to rotate, and the ball screw 802 drives the two docking sliders 803 to move to opposite sides. The docking slider 803 on one side drives the hot box 3 to move along the first guide rail 2, and the docking slider 803 on the other side drives the cold box 5 to move along the second guide rail 4, thereby clamping the insulation board. Insulating foam is filled between the hot box 3 and the cold box 5 and the insulation board. Different temperature conditions are set in the hot box 3 and the cold box 5 to simulate the hot and cold environment of the door / window in actual use. Temperature sensors and other detection devices monitor the temperature changes on both sides of the door / window body 906 in real time, thereby calculating the insulation performance index of the door / window.
