Description

Technical Field

[0001] This utility model relates to the field of door and window insulation testing technology, specifically a door and window insulation performance testing device. Background Technology

[0002] Traditional technologies typically use the conventional hot box method to test the thermal insulation performance of doors and windows. Laboratory tests such as the conventional hot box method and the protective hot plate method require specialized equipment, and the cost of a single test can be as high as several thousand yuan. In addition, the doors and windows need to be transported to the laboratory, which takes several weeks. Furthermore, the laboratory environment cannot simulate real installation conditions, such as sealant aging and profile deformation, resulting in a large deviation between the data and the on-site performance.

[0003] Therefore, there is a need for equipment that can test the thermal insulation performance of doors and windows on-site to reduce testing costs and reduce testing processes and steps. In view of this situation, this utility model proposes a novel solution. Utility Model Content

[0004] The purpose of this invention is to provide a device for testing the thermal insulation performance of doors and windows, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a door and window thermal insulation performance testing device, comprising:

[0006] The base plate has a grid fixed to its top, and a cover plate is installed on the top of the grid via a hinge. The base plate, grid, and cover plate form a cavity for placing doors and windows.

[0007] A perforation with a width and diameter smaller than the door or window to be tested is opened in the middle of the base plate. A rubber strip is fixed around the top of the base plate along the perforation. The door or window to be tested is placed on top of the rubber strip.

[0008] The cover plate is equipped with multiple testing mechanisms for detecting the thermal insulation performance of doors and windows.

[0009] Further, the rubber strip enclosure is composed of four 5cm-7cm rubber strips connected by heat fusion, and the height of the rubber strip enclosure is 5cm-10cm.

[0010] Further, the solution includes a push bar located below the base plate, with an ignition platform mounted on the push bar, and a candle or electronic igniter installed on the ignition platform.

[0011] Further, the cover plate is provided with a number of threaded holes, wherein the number of detection mechanisms corresponds to the number of threaded holes. The detection mechanism includes a screw joint screwed into the threaded hole, and a water bag is fixed in the middle of the screw joint. The length of the water bag is greater than the minimum distance between the cover plate and the door / window to be tested. After the cover plate is closed, the water bag is in direct contact with the door / window to be tested.

[0012] Further, the screw connector is fixed with a hexagonal cap at the top, and a clamping component is provided on the top of the hexagonal cap. The clamping component holds a thermometer, which is inserted into the water bag to detect the water temperature.

[0013] Further, the clamping component includes a first clamp, which is clamped to the edge of the hexagonal cap. A plastic strip is fixed to the first clamp, and a second clamp is fixed to the other end of the plastic strip. The second clamp is used to hold the thermometer.

[0014] Furthermore, the bottom of the base plate is fixed with several support legs, with a gap of 5cm-10cm between the support legs and the ground.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This door and window insulation performance testing device forms a three-sided enclosed test chamber through a base plate, partitions, and a cover plate. Combined with the rubber strip enclosure and the testing mechanism on the cover plate, it can effectively simulate the insulation environment of doors and windows in actual use, making the test results closer to the real situation.

[0017] Meanwhile, the rubber strip enclosure is composed of four rubber strips connected by hot melting and has undergone secondary vulcanization treatment. It can still maintain its elasticity at high temperatures. After the door and window test pieces are placed, they can be manually pressed to produce visible deformation, thereby forming a good airtight layer, effectively preventing heat from leaking from the edges and ensuring the accuracy of heat conduction.

[0018] In addition, the water bag in the testing unit is in direct contact with the doors and windows. Heat is conducted to the water bag, causing the water temperature to rise. The thermometer probe, held by a silicone-coated silicone clamp made of shape-memory metal wire, can be positioned at the geometric center of the water bag, accurately measuring water temperature changes and thus reflecting the insulation performance of the doors and windows. Furthermore, multiple testing units are set up to compare temperature rise differences at various points, providing a comprehensive analysis of the uniformity of door and window insulation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1 As shown, this utility model provides a technical solution: a door and window thermal insulation testing device, comprising:

[0025] A base plate 1 is provided, with a grid 3 fixed to its top. A cover plate 5 is installed on the top of the grid 3 via a hinge. The base plate 1, the grid 3, and the cover plate 5 form a cavity for placing doors and windows. A perforation with a width and diameter smaller than the door or window to be tested is provided in the middle of the base plate 1. A rubber strip 2 is fixed around the perforation on the top of the base plate 1. The door or window to be tested is placed on top of the rubber strip 2. Multiple testing mechanisms 6 for testing the thermal insulation of doors and windows are provided on the cover plate 5.

[0026] like Figure 1 and Figure 2 As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that the rubber strip enclosure 2 is composed of four 5cm-7cm rubber strips connected by hot fusion. The height of the rubber strip enclosure 2 is 5cm-10cm. It is made by hot fusion welding four sections of rubber strips into a closed loop. The joints are subjected to secondary vulcanization treatment to ensure that it still maintains elasticity at a high temperature of 80℃. During installation, the door and window test piece is placed in the center on the rubber strip enclosure 2 and manually pressed to make the enclosure deform visibly.

[0027] like Figure 2 As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that a push bar 7 is provided below the base plate 1, and an ignition platform 8 is provided on the push bar 7. A candle or electronic igniter is installed on the ignition platform 8. The push bar 7 adopts a hollow structure and is filled with ceramic fiber heat insulation cotton (temperature resistant to 1200℃) to ensure that the temperature of the external handle is ≤50℃. The ignition platform 8 can be equipped with an adjustable bracket to support the adjustment of the fire source height and control the heat flow intensity.

[0028] like Figure 2 and Figure 3As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that the cover plate 5 has several threaded holes. The number of the detection mechanism 6 corresponds to the number of threaded holes. The detection mechanism 6 includes a screw joint 601 screwed into the threaded hole. A water bag 603 is fixed in the middle of the screw joint 601. The length of the water bag 603 is greater than the minimum distance between the cover plate 5 and the door / window to be tested. After the cover plate 5 is closed, the water bag 603 is in direct contact with the door / window to be tested. When the cover plate 5 is closed, observe whether the water bag 603 collapses evenly. If the difference in the collapse amplitude is ≤10%, it is qualified. Otherwise, adjust the position of the test piece.

[0029] like Figure 3 As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that a hexagonal cap 602 is fixed to the top of the screw connector 601, and a clamping component is provided on the top of the hexagonal cap 602. The clamping component holds a thermometer 604, which extends into the water bag 603 to detect the water temperature. The clamping component includes a first clamp 605, which is clamped at the edge of the hexagonal cap 602. A shaping strip 606 is fixed to the first clamp 605, and a second clamp 607 is fixed to the other end of the shaping strip 606. The second clamp 607 is used to hold the thermometer 604 and is made of shape memory metal wire wrapped with silicone, which can be bent to position the probe of the thermometer 604 to the geometric center of the water bag 603.

[0030] like Figure 2 and Figure 3 As shown, to ensure the smooth implementation of this embodiment, it is necessary to understand that several support legs 4 are fixed at the bottom of the base plate 1, and the support legs 4 are 10cm-15cm away from the ground.

[0031] The base plate 1, the baffle 3, and the cover plate 5 form a three-sided enclosed test chamber (the top can be opened and closed). The rubber strip enclosure 2 (5-10cm high) forms a rectangular sealing ring on the surface of the base plate. The door and window test specimens are laid flat on the rubber strip enclosure 2, and their edges are compressed by the enclosure to form an airtight layer (compression amount of about 2-3cm) to prevent heat from leaking from the edges at the perforations of the base plate. The glass part of the door and window is directly disconnected from the rubber strip enclosure 2. The 10-15cm ground clearance of the support leg 4 provides operating space for the ignition platform 8 on the push bar 7 below the base plate, while promoting air circulation to avoid local overheating.

[0032] The ignition platform 8 uses an electronic igniter or a candle. Heat is conducted vertically upward through a perforation in the middle of the base plate. The diameter of the perforation is smaller than that of the door or window to be tested, forming a directional heat flow. The size of the perforation limits the heat to be transferred only through the door or window specimen, avoiding bypass heat loss.

[0033] When the cover plate 5 is closed, the water bag 603 is compressed because its length exceeds the distance between the door / window and the cover plate 5, generating a contact pressure of 0.1-0.3MPa, ensuring complete contact with the door / window surface. Heat is conducted to the water bag 603 through the door / window, and then the water temperature rises and the change is recorded by the thermometer 604. At least 3 detection mechanisms 6 are set up to analyze the uniformity of the door / window insulation by comparing the temperature rise differences at each point.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended embodiments and their equivalents.
