Description

Technical Field

[0001] This utility model relates to the technical field of air permeability testing equipment, specifically to adjustable air permeability testing equipment. Background Technology

[0002] Air permeability testing equipment is mainly used to measure the ability of gas to pass through specific materials under certain pressure differential conditions. Its core purpose is to quantify the barrier properties or permeability efficiency of materials, thereby assessing whether the materials meet the performance requirements of specific scenarios such as preservation, moisture permeability, protection, or filtration. Furthermore, the testing requires a large amount of data for comparative analysis, necessitating airflow at different velocities and pressures. Different items also require different vent sizes; for example, materials with good permeability require smaller vents, while those with poor permeability require larger vents. However, existing equipment generally lacks adjustable structures, and the vent sizes are fixed. Therefore, some operators manually place air restrictors with different sized openings at the vents. However, these air restrictors are separately matched and do not work well with the equipment, potentially affecting the testing results. Utility Model Content

[0043] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0044] like Figures 1-10 As shown, the adjustable air permeability testing device includes a placement plate 1 for placing the item to be tested, an upper pipe 2, and a lower pipe 3. The lower pipe 3 is used to connect the fan and the upper pipe 2, and the placement plate 1 has an air vent 11 corresponding to the upper pipe 2.

[0045] Meanwhile, a rotatable adjusting plate 4 is provided between the upper pipe 2 and the lower pipe 3, and the adjusting plate 4 has holes 41 of different sizes. One of the holes 41 is located between the upper pipe 2 and the lower pipe 3 and is used to connect the upper pipe 2 and the lower pipe 3. The lower pipe 3 can move up and down to facilitate the rotation of the adjusting plate 4 and achieve sealing.

[0046] Therefore, in actual use, by rotating the adjusting plate 4, holes 41 of different sizes can be positioned between the upper pipe 2 and the lower pipe 3, thereby adjusting the wind speed and wind pressure.

[0047] Furthermore, the air vent 11 is equipped with a detachable adjusting component 5, and the bottom of the adjusting component 5 is located between the upper pipe 2 and the air vent 11, and the adjusting component 5 has an outlet.

[0048] Therefore, in actual use, by replacing the adjusting parts 5 with outlets of different sizes, the wind speed and wind pressure can be adjusted and the outlet can be adapted to the item to be tested.

[0049] Therefore, this utility model, with its adjusting plate 4 having holes 41 of different sizes and a detachable adjusting component 5, allows for adjustment of wind speed and wind pressure by rotating the adjusting plate 4 and replacing the adjusting component 5, thus adapting the outlet to the appropriate item. Furthermore, since it involves secondary adjustment, the adjustment range is relatively large, resulting in a wide range of applications. Simultaneously, the lower pipe 3 can move up and down, allowing it to move upwards to cooperate with the upper pipe 2 to clamp the adjusting plate 4, thereby achieving a seal. It can also move downwards to facilitate the rotation of the adjusting plate 4.

[0050] like Figure 5 and Figure 6 As shown, the adjusting member 5 includes a top plate 51 and a mounting ring 52 disposed at the bottom of the top plate 51. The top plate 51 is located between the item to be tested and the placement plate 1 and has an outlet. The mounting ring 52 is located between the upper pipe 2 and the air outlet 11.

[0051] Meanwhile, a second limiting component is provided between the bottom of the top plate 51 and the upper surface of the placement plate 1, and a first limiting component is provided between the mounting ring 52 and the air vent 11. Therefore, in actual use, the installation and limiting of the adjusting component 5 are achieved by the matching of the first and second limiting components, that is, the two limiting structures ensure the stability of the installation.

[0052] Furthermore, the top plate 51 is located between the item to be tested and the placement plate 1, meaning that the item to be tested is not completely attached to the placement plate 1, which makes it easier to take the item to be tested out.

[0053] The structure of the second limiting component is as follows: First, the second limiting component includes a slider 3 53 and a slide groove 12. The slider 3 53 is located at the bottom of the top plate 51 and is L-shaped. The slider 3 53 includes a limiting part 531 and a connecting part 532. The connecting part 532 is used to connect the limiting part 531 and the top plate 51. The slide groove 12 is located on the upper surface of the placement plate 1. A limiting groove is opened at the bottom of one side of the slide groove 12. That is, the slide groove 12 and the limiting groove are also similar to an L-shape after combination.

[0054] Therefore, in actual use, by placing the slider 3 53 in the slide groove 12 and moving it along the slide groove 12, the end of the limiting part 531 is located in the limiting groove, thereby realizing installation and limiting.

[0055] Meanwhile, the structure of the limiting component one is as follows: First, the limiting component one includes a positioning bead 13, and at least one positioning bead 13 is provided on the inner wall of the air vent 11, and a positioning groove 521 is opened on the outer side of the mounting ring 52 corresponding to the positioning bead 13.

[0056] The positioning bead 13 is a load device consisting of a housing, spring, ball, or column, which can be installed and limited by cooperating with the positioning groove 521.

[0057] like Figure 5 and Figure 6 As shown, outlets of different sizes can be directly formed or formed by other components, namely, partitions 54. Specifically, the top plate 51 has an opening 511 in the middle, and a partition 54 is installed within the opening 511 to divide it into at least two outlets. The bottom of the partition 54 is located inside the upper pipe 2. Therefore, in actual use, the number, size, and even shape of the outlets can be adjusted by setting different partitions 54 within the opening 511. The partition 54 can be integrally formed or detachable, i.e., the side wall of the opening 511 has slots for inserting the partition 54.

[0058] Secondly, other structures related to the adjusting component 5 are as follows: First, a protruding ring 522 is provided at the bottom of the mounting ring 52, and a step 21 is provided on the outside of the upper pipe 2, with a mounting groove 211 corresponding to the protruding ring 522 on the step 21. Therefore, in actual use, installation and positioning are achieved by the contact between the step 21 and the bottom of the mounting ring 52, and by the adaptation between the protruding ring 522 and the mounting groove 211.

[0059] Meanwhile, the placement plate 1 has a groove 14 for placing the sealing ring on the inner side of the limiting component 2, and a groove 22 for the sealing ring is opened on the outer side of the top of the upper pipe 2. Therefore, in actual use, the sealing ring ensures airtightness.

[0060] Furthermore, the upper pipe 2 includes a pipe body 23 and a connector 24, and the connector 24 is used to connect the pipe body 23 and the adjusting member 5, and a connecting ring 241 is provided on the top of the connector 24, and the connecting ring 241 is located inside the mounting ring 52.

[0061] Therefore, in actual use, by splitting the upper pipe 2 into two parts, the processing of the connecting part 24 is facilitated, which in turn allows for better cooperation with the adjusting part 5. At the same time, corresponding to the partition 54, the connecting ring 254 is located between the partition 54 and the mounting ring 52.

[0062] like Figures 1-10As shown, the structure of the regulating plate 4 is as follows: First, a motor 10 is connected to the top of the regulating plate 4, and the motor 10 is connected to a bracket 7, and the bracket 7 is movably positioned on one side of the upper pipe 2.

[0063] Meanwhile, the structure related to the movement of the bracket 7 is as follows: First, a slide rail 71 is provided on the outside of the bracket, and the present invention also includes a side plate 8, which is located below the placement plate 1. An assembly 81 is provided on one side of the side plate 8, and a slider 82 is provided on the side of the assembly 81 near the motor 10. The slider 82 is provided on the slide rail 71 and moves along the slide rail 71.

[0064] Therefore, in actual use, the slider 82 and the slide rail 71 are matched to guide the movement, and the top of the bracket 7 is connected to the cylinder 91 for driving the movement of the bracket 7. Moreover, the adjustment plate 4 of this utility model is connected to the top of the motor 10, so the space on one side of the lower pipe 3 can be left open to facilitate the placement of the fan, thereby making reasonable layout of the internal space and reducing the overall volume.

[0065] like Figures 1-10 As shown, the structure of the lower pipe 3 is as follows: First, the lower pipe 3 includes a moving section 31 and a connecting section 32, and the connecting section 32 is used to connect the moving section 31 and the fan.

[0066] The movement of the lower pipe 3 includes driving and guiding. The driving structure for the movement of the lower pipe 3 is as follows: First, mounting part 1 61 and mounting part 2 62 are respectively provided on both sides of the moving section 31. Mounting part 1 61 and mounting part 2 62 are connected by fasteners (such as screws) and set on the lower pipe 3. Mounting part 1 61 and mounting part 2 62 are respectively connected to cylinder 1 92 and cylinder 2 93.

[0067] Therefore, in actual use, the cylinders 92 and 93 drive the mounting parts 61 and 62 to move up and down, thereby moving the moving section 31 up and down, which in turn moves the lower pipe 3 up and down. Furthermore, the mounting parts are T-shaped and have curved surfaces corresponding to the moving section 31.

[0068] Meanwhile, the guide structure used for moving the lower pipe 3 is as follows: First, this utility model also includes a side plate 8, and the side plate 8 is located below the placement plate 1. The side plate 8 is provided with a slide rail 83 on the side near the moving section 31. The moving section 31 is provided with a slider 311 on the side near the side plate 8. The slider 311 is set on the slide rail 83 and moves along the slide rail 83.

[0069] Therefore, in actual use, the slider 311 and the slide rail 83 are matched to guide the movement.

[0070] like Figures 1-10As shown, the present invention also includes a pressing member 20, which is disposed above the placement plate 1 and is movable, and the pressing member 20 has a through hole 201 in the middle for gas circulation.

[0071] The movement of the pressing member 20 is achieved by connecting to and driving the cylinder 4 94. Guide rods 95 are provided on both sides of the cylinder 4 94. The present invention also includes a fixed guide sleeve 96, in which the guide rods 95 move.

[0072] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. However, this utility model is not limited to the above embodiments; therefore, various changes and modifications can be made without departing from the principles and scope of this utility model, and all such changes and modifications fall within the scope of the claimed utility model.
