Description
Technical Field
[0001] This utility model relates to the field of door and window insulation technology, and in particular to an auxiliary device for testing the thermal insulation performance of doors and windows. Background Technology
[0002] Doors and windows are classified as enclosure components or partition components according to their location. They have different design requirements and must have functions such as heat preservation, heat insulation, sound insulation, waterproofing, and fireproofing. New requirements include energy saving. In cold regions, the heat lost through gaps in doors and windows accounts for about 25% of the total heating heat consumption. Doors and windows are important components of the building envelope system.
[0003] Chinese utility model patent CN217820124U discloses a testing device for the thermal insulation performance of doors and windows, including a housing. An internal frame is fixedly installed on the inner wall of the housing. An embedding groove is opened in the middle of the inner wall of the internal frame. A sealing strip is fixedly installed on the inner wall of the embedding groove. A top groove is provided at the top of the internal frame. The top groove is opened in the inner cavity at the top of the housing, and a sealing frame is fixedly installed on the inner wall of the top groove. During testing, the door and window test piece is inserted through the top groove, so that the bottom end of the door and window test piece is located inside the embedding groove. At this time, the door and window test piece is in a positioned state, and the inner walls of the sealing strip and the sealing frame are respectively in contact with the side walls at both ends of the door and window test piece.
[0004] Regarding the aforementioned technologies, the inventors believe that the following defects exist: When the above-mentioned device is used, the door and window test specimen is passed through the top groove. During this process, the inner wall of the sealing strip and the sealing frame is in contact with the side walls at both ends of the door and window test specimen, which results in a large friction between the inner wall of the sealing strip and the sealing frame and the side walls at both ends of the door and window test specimen. This makes it inconvenient for the staff to move the door and window test specimen by requiring a lot of force. Utility Model Content
[0005] To address the aforementioned problems, this utility model provides an auxiliary device for testing the thermal insulation performance of doors and windows.
[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an auxiliary device for testing the thermal insulation performance of doors and windows, including a mounting box, a square hole on the top of the mounting box, a fixed frame fixedly installed on one side of the square hole and a sliding frame slidably installed on the other side of the mounting box, a driving component for driving the sliding frame to slide inside the mounting box, a first rubber sealing ring installed on the side of the fixed frame near the square hole, a second rubber sealing ring installed on the side of the sliding frame near the square hole, temperature sensors installed on both sides of the top of the mounting box near the square hole, and a heating box installed inside the mounting box on the side of the fixed frame away from the square hole.
[0007] By adopting the above technical solution, an installation box, a square hole, a drive assembly, temperature sensors, and a heating chamber are set up. The door and window specimen is placed into the installation box through the square hole. After entering, one side of the specimen contacts the first rubber sealing ring. Then, the drive assembly is activated, which drives the sliding frame box to slide towards the specimen, causing one side of the second rubber sealing ring to contact the specimen. The specimen is then clamped between the first and second rubber sealing rings. Subsequently, the heating chamber is activated to heat one side of the installation box. After heating for a period of time, the two temperature sensors detect the temperature difference between the two sides of the specimen, thereby evaluating its thermal insulation performance. When the specimen enters and exits the square hole, only one side contacts the first rubber sealing ring, resulting in low friction. This makes it easier for workers to move the specimen without requiring much force.
[0008] Furthermore, horizontal grooves are provided on the inner walls of opposite sides of the mounting box, and sliders are provided on both sides of the sliding frame, with the sliders slidably connected to the corresponding grooves.
[0009] By adopting the above technical solution, and setting up sliding grooves and sliders, the stability of the sliding frame is ensured.
[0010] Furthermore, the sliding frame has several horizontally opened sliding holes, and a sliding rod is slidably arranged in the sliding holes. An installation frame is provided on the side of the sliding rod near the fixed frame. A compression spring is sleeved on the rod between the sliding frame and the installation frame. A baffle is provided on the end of the sliding rod away from the installation frame. The second rubber sealing ring is connected to the side of the installation frame near the fixed frame.
[0011] By adopting the above technical solution, a sliding hole, a sliding rod, a mounting frame, and a compression spring are set up. After the driving component drives the sliding frame to slide and the second rubber sealing ring contacts the door and window test piece, the driving component continues to drive the sliding frame to slide a little further, so that the compression spring is compressed. This allows the compression spring to continuously provide a thrust to the mounting frame in the direction of the door and window test piece, ensuring the stability of the contact between the second rubber sealing ring and the door and window test piece.
[0012] Furthermore, the drive assembly includes a support frame disposed within the mounting box, a drive cylinder is horizontally disposed on the top of the support frame, a connecting frame is disposed at the end of the piston rod of the drive cylinder, and the connecting frame is connected to the sliding frame.
[0013] By adopting the above technical solution, a support frame, a drive cylinder, and a connecting frame are set up. The drive cylinder pushes the connecting frame to move, thereby driving the sliding frame to move.
[0014] Furthermore, a third rubber sealing ring is fitted on the outer wall of the mounting frame.
[0015] By adopting the above technical solution and setting a third rubber sealing ring, the sealing between the mounting frame and the mounting box is ensured.
[0016] Furthermore, the bottom of the mounting box has an opening directly below the square opening, and a lifting block is vertically slidably arranged inside the opening. A fixing frame is provided at the bottom of the mounting box, and a pushing cylinder is vertically arranged on the fixing frame. The piston rod of the pushing cylinder is upward and connected to the lifting block.
[0017] By adopting the above technical solution, an opening, a lifting block, a fixing frame, and a pushing cylinder are set up. After the test is completed, the lifting block is pushed up by the pushing cylinder, so that the door and window test piece is pushed up, and the upper part of the door and window test piece extends out of the installation box, making it convenient for the staff to take out the door and window test piece.
[0018] Furthermore, the side of the first rubber sealing ring away from the fixing frame is coplanar with the wall of the square hole adjacent to the fixing frame.
[0019] By adopting the above technical solution, the side of the first rubber sealing ring away from the fixed frame is set to be coplanar with the hole wall of the square hole near the fixed frame, ensuring smooth entry and exit of the door and window specimens into and out of the square hole.
[0020] In summary, this utility model has the following beneficial effects:
[0021] 1. In this application, by adopting the above-mentioned technical solution, an installation box, a square hole, a drive assembly, a temperature sensor, and a heating box are set up. The door and window specimen is placed into the installation box through the square hole. After entering, one side of the door and window specimen contacts the first rubber sealing ring. Then, the drive assembly is activated, which drives the sliding frame box to slide towards the door and window specimen, so that one side of the second rubber sealing ring contacts the door and window specimen, and the door and window specimen is clamped between the first rubber sealing ring and the second rubber sealing ring. Then, the heating box is activated to heat one side of the installation box. After heating for a period of time, the two temperature sensors detect the temperature difference between the two sides of the door and window specimen, thereby evaluating the thermal insulation performance of the door and window specimen. When the door and window specimen enters and exits the square hole, only one side contacts the first rubber sealing ring, resulting in less friction. This makes it more convenient for workers to move the door and window specimen without requiring much force.
[0022] 2. In this application, a sliding hole, a sliding rod, a mounting frame, and a compression spring are provided. After the driving component drives the sliding frame to slide and the second rubber sealing ring contacts the door and window test piece, the driving component continues to drive the sliding frame to slide slightly, so that the compression spring is compressed. This allows the compression spring to continuously provide a thrust to the mounting frame in the direction of the door and window test piece, ensuring the stability of the contact between the second rubber sealing ring and the door and window test piece.

[0029] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0030] like Figure 1-5 As shown in the illustration, this application discloses an auxiliary device for testing the thermal insulation performance of doors and windows, including a mounting box 10, a drive assembly 50, a temperature sensor 12, and a heating box 14. A square hole 11 is vertically formed at the top of the mounting box 10. The width and length of the square hole 11 are the same as the width and length of the door / window specimen. The width of the bottom of the mounting box 10 is the same as the length of the door / window specimen, and the height of the inner sidewall of the mounting box 10 is the same as the height of the door / window specimen. A fixed frame 20 is fixedly installed on one side of the square hole 11 inside the mounting box 10, and a sliding frame 30 is slidably installed on the other side. The sliding direction of the sliding frame 30 is consistent with the length direction of the mounting box 10. The drive assembly 50 is disposed inside the mounting box 10 and is used to drive the sliding frame 30 to slide.
[0031] A first rubber sealing ring 21 is provided on the side of the fixed frame 20 near the square hole 11, and a second rubber sealing ring 31 is provided on the side of the sliding frame 30 near the square hole 11. Temperature sensors 12 are provided on both sides of the square hole 11 at the top of the mounting box 10. The heating box 14 is located inside the mounting box 10 on the side of the fixed frame 20 away from the square hole 11. The door and window specimen is placed into the mounting box 10 through the square hole 11. After entering, one side of the door and window specimen contacts the first rubber sealing ring 21. Then, the drive assembly 50 is activated, which drives the sliding frame 30 to slide towards the door and window specimen, so that the second rubber sealing ring 31 comes into contact with the door and window specimen, and the door and window specimen is clamped between the first rubber sealing ring 21 and the second rubber sealing ring 31. Then, the heating box 14 is activated to heat one side of the mounting box 10. After heating for a period of time, the two temperature sensors 12 detect the temperature difference between the two sides of the door and window specimen, thereby evaluating the thermal insulation performance of the door and window specimen. When the door and window specimen enters and exits the square hole 11, only one side contacts the first rubber sealing ring 21, resulting in low friction. This makes it easier for workers to move the specimen without requiring much force. The side of the first rubber sealing ring 21 away from the fixed frame 20 is coplanar with the wall of the square hole 11 near the fixed frame 20, ensuring smooth entry and exit of the door and window specimen from the square hole 11.
[0032] Specifically, horizontal grooves 13 are provided on the inner sidewalls of opposite sides inside the mounting box 10. Slider blocks 32 are provided on both sides of the sliding frame 30, and the sliders 32 are slidably connected to the corresponding grooves 13 to ensure the stability of the sliding frame 30. Several sliding holes are horizontally provided on the sliding frame 30, and sliding rods 40 are slidably installed in the sliding holes. The mounting frame 41 is provided on the side of the sliding rods 40 near the fixed frame 20. A compression spring 42 is sleeved on the rod of the sliding rod 40 between the sliding frame 30 and the mounting frame 41. One end of the compression spring 42 is connected to the sliding frame 30 and the other end is connected to the mounting frame 41. A baffle 43 is provided on the end of the sliding rod 40 away from the mounting frame 41 to limit the sliding rod 40. The second rubber sealing ring 31 is connected to the side of the mounting frame 41 near the fixed frame 20. After the drive assembly 50 drives the sliding frame 30 to slide and the second rubber sealing ring 31 contacts the door and window specimen, the drive assembly 50 continues to drive the sliding frame 30 to slide slightly, so that the compression spring 42 is compressed. The compression spring 42 continuously provides a thrust to the mounting frame 41 in the direction of the door and window specimen, ensuring the stability of the contact between the second rubber sealing ring 31 and the door and window specimen. At this time, the slider 32 is located at the end of the slide groove 13 near the square hole 11. A third rubber sealing ring 44 is fitted on the outer wall of the mounting frame 41 to ensure the sealing between the mounting frame 41 and the mounting box 10.
[0033] During setup, the drive assembly 50 includes a support frame 51 disposed within the mounting box 10. A drive cylinder 52 is horizontally disposed on the top of the support frame 51. A connecting frame 53 is disposed at the end of the piston rod of the drive cylinder 52. The connecting frame 53 is connected to the sliding frame 30. The drive cylinder 52 pushes the connecting frame 53 to move, thereby moving the sliding frame 30.
[0034] In the specific setup, an opening 60 is provided at the bottom of the mounting box 10, directly below the square opening. A lifting block 61 is vertically slidably installed inside the opening 60. A fixing frame 62 is provided at the bottom of the mounting box 10, and a pushing cylinder 63 is vertically installed on the fixing frame 62. The piston rod of the pushing cylinder 63 is upward and connected to the lifting block 61. After the test is completed, the lifting block 61 is pushed up by the pushing cylinder 63, causing the door and window specimen to be pushed up, so that the upper part of the door and window specimen extends out of the mounting box 10, making it easy for the staff to remove the door and window specimen. Several ventilation holes are provided on the box plate of the heating chamber 14. Several infrared heating lamps are provided inside the heating chamber 14. After the infrared heating lamps are powered on, the tungsten filaments heat up under the action of AC voltage and heat the gas in the quartz tube, thereby generating infrared electromagnetic waves. The infrared rays radiate outward and heat the air.
[0035] The operating principle of the auxiliary device for testing the thermal insulation performance of doors and windows in this embodiment is as follows: A door / window specimen is placed into the mounting box 10 through the square hole 11. After insertion, one side of the specimen contacts the first rubber sealing ring 21. Then, the drive cylinder 52 is activated to move the connecting frame 53, causing it to slide towards the specimen, making one side of the second rubber sealing ring 31 contact the specimen. The drive assembly 50 continues to drive the sliding frame 30 to slide slightly, compressing the compression spring 42. The specimen is then clamped between the first rubber sealing ring 21 and the second rubber sealing ring 31. Subsequently, the heating chamber 14 is activated to heat one side of the mounting box 10. After heating for a period of time, the two temperature sensors 12 detect the temperature difference between the two sides of the specimen, thereby evaluating the thermal insulation performance of the specimen. Subsequently, the drive cylinder 52 drives the sliding frame 30 and the mounting frame 41 to move slightly away from the fixed frame 20, so that the second rubber sealing ring 31 can no longer press against the door and window test piece. Then, the push cylinder 63 is activated to push the lifting block 61 upward, causing the door and window test piece to be pushed upward, so that the upper part of the door and window test piece extends out of the mounting box 10, and the staff removes the door and window test piece. Then, the drive cylinder 52 drives the sliding frame 30 and the mounting frame 41 to reset.
[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
