Description

Technical Field

[0001] The utility model relates to the technical field of pipeline sealing detection equipment, in particular to a flexible polyurethane foam rubber insulated air conditioning duct sealing detection equipment. Background Art

[0002] Flexible polyurethane foam rubber is a common thermal insulation material widely used in air conditioning duct systems to improve the system's energy efficiency and stability. To ensure that the duct system does not leak during operation, air tightness testing can help detect tiny cracks and gaps in duct connections, interfaces, or materials, ensuring the efficiency and stability of the system. Air tightness testing equipment typically includes an air tightness tester. Current air tightness testers typically require the use of a hose to connect to the air conditioning duct for testing. This connection method helps to correctly connect the pressure sensor or air tightness detector of the test equipment to the duct system, thereby performing an effective air tightness test. However, the hoses used in the air tightness tester are often connected on-site, which not only requires additional time and manual operation, but also increases the complexity and workload of on-site testing. At the same time, multiple hose connections can easily reduce the docking accuracy, resulting in gaps or incomplete alignment at the joints, thereby increasing the possibility of air leaks.

[0026] Example

[0027] like Figure 1-5 As shown, the flexible polyurethane foam rubber insulated air conditioning duct sealing detection equipment proposed by the utility model includes a cart 1 and an air tightness tester 11 and a fan 12 arranged on the cart 1. The top of the fan 12 is fixedly connected to a connecting pipe 13, and the top of the connecting pipe 13 is fixedly connected to one end of a hose 14. The fan 12 is connected to the hose 14. It also includes: a storage box 2 for storing the hose 14. The storage box 2 can avoid multiple connections of the hose 14. Frequent connection will cause wear of the hose 14 and the connector, affecting the service life and sealing performance of the hose 14. In addition, frequent connection of the hose 14 is not only easy to introduce pollutants or foreign matter, affecting the performance of the system, but also increases the damage to the hose 14 and the connector, thereby increasing the possibility of failure. Placing the hose 14 in the storage box 2 can effectively prevent these problems and can be directly taken out when in use. Placing the hose 14 in the storage box can reduce contact and wear, thereby extending the service life of the hose 14. The trolley 1 is fixedly connected to the upper surface of one end of the trolley 1 near the fan 12; the rotatable cover 4 is rotatably mounted on the top opening of the storage box 2, and a handle 42 is fixedly connected to the upper surface of the rotatable cover 4. The handle 42 is used to make it easier and more labor-saving to rotate the rotatable cover 4 up and down. The rotatable cover 4 and the storage box 2 are provided with a second slot 41 and a first slot 21 for the hose 14 to be inserted. Each pair of the second slot 41 and the first slot 21 facing each other is used to clamp the hose 14, so as to prevent the closed rotatable cover 4 from pressing on the hose 14, which would cause the hose 14 to be flattened and affect normal use; the tray mechanism is set in the storage box 2 to drive the coiled hose 14 up and down; the switch mechanism is slidably mounted on the top of the storage box 2, and when manually pushed and pulled, the storage box 2 and the rotatable cover 4 are tightly clamped.

[0028] Furthermore, the tray mechanism includes a sliding base plate 3 slidably arranged in the storage box 2, a pair of limit sliders 32 are fixedly connected to the sliding base plate 3, a pair of limit slide grooves 26 for the limit sliders 32 to slide are provided inside the storage box 2, a winding support block 31 is fixedly connected to the upper surface of the sliding base plate 3, a mounting cavity 35 is provided at the bottom of the winding support block 31, a supporting base block 33 is fixedly connected to the inner bottom wall of the storage box 2, a cylinder 34 installed in the mounting cavity 35 is fixedly connected to the upper surface of the supporting base block 33, and a piston rod of the cylinder 34 is fixedly connected to the inner wall of the mounting cavity 35.

[0029] Furthermore, the switch mechanism includes a sliding hole 22 defined in the top of the storage box 2. A pull spring 24 is fixedly connected to the interior of the sliding hole 22. The pull spring 24 ensures that the U-shaped lever 23 automatically moves toward the rotating cover 4 when no tension is applied. The end of the U-shaped lever 23, away from the sliding hole 22, remains engaged in a slot 43. The end of the pull spring 24, away from the inner wall of the sliding hole 22, is fixedly connected to the U-shaped lever 23. The outer wall of the U-shaped lever 23 is provided with a pair of linearly arranged protrusions 25. These protrusions increase friction between the hand and the U-shaped lever 23, preventing it from sliding when manually pulled. The rotating cover 4 is provided with a slot 43 for inserting one end of the U-shaped lever 23.

[0030] In this embodiment, when it is necessary to use the air conditioning duct sealing detection equipment, such as Figure 1 As shown, the handle 42 is lifted upward to drive the rotating cover 4 to open upward, so that the rotating cover 4 is as shown in FIG. Figure 2 As shown. The cylinder 34 on the support base 33 within the mounting cavity 35 is then activated. Once activated, the piston rod pushes the winding support block 31 out of the storage box 2. The bottom end of the winding support block 31 then drives the sliding base 3 to slide along the inner wall of the storage box 2. The limiting slider 32 on the sliding base 3 slides along the limiting groove 26 within the storage box 2, allowing the winding support block 31 to slide steadily out of the storage box 2. Once the limiting slider 32 on the sliding base 3 slides along the limiting groove 26 on the storage box 2 to its limit position, the end of the hose 14 away from the connecting pipe 13 can be removed from the winding support block 31 by twisting it. This is a simple and easy operation.

[0031] When the hose 14 is used up, the cylinder 34 can be activated to retract the winding support block 31 and the sliding bottom plate 3 into the storage box 2, and the hose 14 can be used as a storage box. Figure 3 Place the end of the hose 14 away from the connecting pipe 13 on the upper surface of the sliding base plate 3, and make the hose 14 wrap around the winding support block 31, and finally Figure 2Place it as shown. Then rotate it downward to cover the rotating cover 4, and make the second slot 41 on the rotating cover 4 and the corresponding first slot 21 on the storage box 2 clamp the hose 14, so that the lower surface of the rotating cover 4 and the top of the storage box 2 are closed. Before that, pull the U-shaped clamping rod 23 away from the storage box 2 so that the end of the U-shaped clamping rod 23 away from the sliding hole 22 cannot block the closing of the storage box 2 and the rotating cover 4. When the storage box 2 and the rotating cover 4 are closed, release the U-shaped clamping rod 23. At this time, the elastic tension of the U-shaped clamping rod 23 in the sliding hole 22 pulls the spring 24 in the sliding hole 22, so that the end of the U-shaped clamping rod 23 away from the sliding hole 22 is inserted into the clamping slot 43 on the rotating cover 4, so that the storage box 2 and the rotating cover 4 cannot be rotated and opened at will.
