Description

Technical Field

[0001] This utility model relates to the technical field of door and window testing equipment, and in particular to a water circulation structure for a door and window testing instrument. Background Technology

[0002] After doors and windows are manufactured, one of their main functions is to prevent wind and rain from entering the room, and their ability to protect against wind and rain directly determines their performance. Therefore, testing the sealing performance of doors and windows is crucial. Currently, the industry typically uses simulated rainy weather to test the sealing performance of doors and windows.

[0003] During the test, water was sprayed directly onto the doors and windows through a nozzle to test their rain resistance. However, in this test method, the sprayed water flows directly into the sewer pipes, resulting in a large waste of water resources. This waste of water resources not only increases the test cost but also has an adverse impact on environmental protection. Utility Model Content

[0025] Example 1: Please refer to the accompanying drawings. This invention provides a technical solution:

[0026] A water circulation structure for a door and window inspection instrument, such as Figure 1 As shown, the device includes a base 1, with a water tank 2 and support columns 3 fixedly connected to the upper end of the base 1. A pair of support columns 3 are located on the left and right sides of the water tank 2. A water spray mechanism 5 is installed between the two support columns 3. The water spray mechanism 5 is used to test the sealing performance of doors and windows. It also includes:

[0027] Fixing mechanism 4 is installed between two support columns 3 and is used to fix doors and windows.

[0028] The drive mechanism 6 and the fixing mechanism 4 are installed inside the support column 3. The drive mechanism 6 is used to drive the fixing mechanism 4 to move up and down.

[0029] Water spraying mechanism 5 sprays water onto doors and windows to conduct a sealing test, while fixing mechanism 4 can firmly fix the doors and windows in the test position to ensure that the doors and windows will not shift or loosen during the test; driving mechanism 6 can adjust the height of fixing mechanism 4 according to the needs of doors and windows of different heights, making the test more flexible and adaptable.

[0030] like Figure 2 As shown, the water spraying mechanism 5 includes a water pump 51 and branch pipes 54. The water pump 51 is fixedly connected inside the water tank 2. The water outlet end of the water pump 51 is fixedly connected to a main pipe 52. The end of the main pipe 52 away from the water pump 51 is fixedly connected to a three-way pipe 53. A pair of branch pipes 54 are provided and fixedly connected between two support columns 3. The left ends of the two branch pipes 54 are fixedly connected to the two water outlet ends of the three-way pipe 53 respectively. Spray nozzles 55 are fixedly connected at equal intervals at the lower end of the branch pipes 54.

[0031] The three-way pipe 53 is equipped with a flow divider valve 531 inside;

[0032] like Figure 3-4 As shown, the fixing mechanism 4 includes a water collection box 41 and a pressure plate 49. The water collection box 41 is set between two support columns 3. Support rods 42 are fixedly connected at equal intervals inside the water collection box 41. A drain pipe 43 is fixedly connected to the lower end of the water collection box 41. The lower end of the drain pipe 43 extends into the water tank 2. Support frames 44 are fixedly connected to the upper ends of both the left and right sides of the water collection box 41. An installation groove 45 is opened on the upper left end face of the support frame 44. A limit post 46 is fixedly connected inside the installation groove 45. A limit block 48 is slidably connected to the side wall of the limit post 46. The pressure plate 49 is fixedly connected between the two limit blocks 48. A spring 47 is sleeved on the side wall of the limit post 46. The lower end of the spring 47 is fixedly connected to the upper end of the limit block 48. The upper end of the spring 47 is fixedly connected to the inner wall of the installation groove 45.

[0033] The lower end face of the pressure plate 49 is provided with a reserved slot 491.

[0034] The coordinated operation of the water spraying mechanism 5 and the fixing mechanism 4 enables efficient testing of the sealing performance of doors and windows. The water pump 51 in the water spraying mechanism 5 draws water from the water tank 2, which is then diverted through the main pipe 52 and the three-way pipe 53, and then evenly sprayed onto the surface of the doors and windows through the branch pipe 54 and the nozzle 55 to simulate the rainfall situation in actual use, thereby testing the sealing performance of the doors and windows. The diversion valve 531 in the three-way pipe 53 can adjust the distribution of water flow as needed to ensure the uniformity of water spraying.

[0035] The water collection box 41 in the fixing mechanism 4 is used to collect water flowing down from the surface of the door and window during the water spraying process, and guides it back to the water tank 2 through the drain pipe 43 to realize the recycling of water resources. The structure composed of the support frame 44, the limiting post 46, the limiting block 48 and the spring 47 on the water collection box 41 can firmly fix the door and window in the test position. At the same time, the reserved slot 491 at the lower end of the pressure plate 49 can limit the fixed door and window, further enhancing the fixing effect. This not only improves the stability and reliability of the test, but also effectively solves the problem of water waste in the existing technology.

[0036] Example 2: The structure of this example is basically the same as that of Example 1, except that, as shown in Example 2... Figure 2 As shown, the drive mechanism 6 includes a threaded rod 61 and a motor 62. A limiting groove 31 is provided on the left end face of the support column 3. A pair of threaded rods 61 are provided and are rotatably connected inside the limiting groove 31 respectively. The motor 62 is fixedly connected to the upper end of the support column 3.

The moving block 63 is located inside the limiting groove 31 and is slidably connected thereto. Both moving blocks 63 are fixedly connected to the left and right ends of the water collection box 41.

[0037] Through the design of the drive mechanism 6, the vertical movement function of the fixing mechanism 4 is realized. The motor 62 is fixed on the upper end of the support column 3, and its output shaft is connected to the upper end of the threaded rod 61. The threaded rod 61 is rotatably connected in the limiting groove 31 on the left end face of the support column 3. The side wall of the threaded rod 61 is connected to the moving block 63 by thread. The moving block 63 slides in the limiting groove 31 and is fixedly connected to the left and right ends of the water collection box 41. When the motor 62 starts, it drives the threaded rod 61 to rotate, and the moving block 63 on the threaded rod 61 moves up and down along the limiting groove 31, thereby driving the water collection box 41 and the doors and windows fixed on it to move up and down. This structure can flexibly adjust the height position of the fixing mechanism 4 according to different sizes of doors and windows, so that it can adapt to the testing needs of various specifications of doors and windows, and further improve the versatility and practicality of the door and window testing instrument.
