[0002] Underwear is one of the most popular clothing categories among consumers in the textile and apparel market. It is known as the "second skin of the human body." The main functions of underwear are to keep warm, absorb sweat, protect the skin, and prevent staining of outer clothing. With the improvement of people's living standards, modern underwear is also required to adjust the body shape, and play certain decorative and health care roles. Therefore, the concept of underwear has changed a lot. In addition to general close-fitting underwear, it is also divided into repair underwear, decorative underwear, shaping underwear, and exercise underwear. During the processing of knitted underwear fabrics, breathability testing is required, which requires the use of breathability testing equipment.

[0003] Existing underwear breathability testing devices require placing the underwear fabric on a sealed box and securing it by closing the two sealed boxes. This requires manual intervention to secure the fabric on both sides to prevent the edges from slipping out and the seal from being too tight. This results in poor securing of the underwear material, low sealing performance, and consequently, inaccurate test results, making the devices impractical. Utility Model Content

[0004] The purpose of this utility model is to provide an underwear breathability testing device to solve the problems mentioned in the background art, such as the inconvenience of fixing underwear materials when testing the breathability of underwear fabrics, poor fixing effect, low sealing performance, which affects the accuracy of the test results and the lack of practicality.

[0005] This utility model provides the following technical solution: a device for testing the breathability of underwear, including a base, a U-shaped mounting bracket fixedly connected to the top of the base, symmetrically provided sliding grooves on the inner walls of both sides of the U-shaped mounting bracket, a cylinder fixedly mounted on the top of the U-shaped mounting bracket, a cylinder push rod fixedly connected to the output end of the cylinder, a fixing mechanism fixedly connected to the output end of the cylinder push rod, a lower sealing box fixedly connected to the middle of the top of the base, a sealing groove provided on the top of the lower sealing box, an air pump fixedly mounted on the top of the base, an air supply pipe fixedly mounted to the output end of the air pump, the end of the air supply pipe away from the air pump being installed on the outside of the lower sealing box, and clamping mechanisms symmetrically fixedly connected to the bottom of the inner walls of both sides of the U-shaped mounting bracket.

A sealing frame strip is fixedly connected to the bottom of the upper sealing box. A pressure detector is fixedly installed on the top of the inner cavity of the upper sealing box.

[0007] As a preferred embodiment of the above technical solution, the bidirectional threaded shaft extends through the fixed plate into the interior of the second moving groove, and the end of the bidirectional threaded shaft away from the second motor is connected to the bearing of the fixed plate.

[0008] As a preferred embodiment of the above technical solution, the insertion rod matches the insertion hole, and sliders are symmetrically fixedly connected to both sides of the fixing plate.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1As shown, this utility model provides a technical solution: a device for testing the breathability of underwear, including a base 1, a U-shaped mounting bracket 2 fixedly connected to the top of the base 1, symmetrically provided sliding grooves 7 on the inner walls of both sides of the U-shaped mounting bracket 2, a cylinder 4 fixedly mounted on the top of the U-shaped mounting bracket 2, a cylinder push rod 5 fixedly connected to the output end of the cylinder 4, a fixing mechanism 6 fixedly connected to the output end of the cylinder push rod 5, a lower sealing box 8 fixedly connected to the middle of the top of the base 1, a sealing groove 11 provided on the top of the lower sealing box 8, an air pump 9 fixedly mounted on the top of the base 1, an air supply pipe 10 fixedly mounted on the output end of the air pump 9, and the end of the air supply pipe 10 away from the air pump 9 installed on the outside of the lower sealing box 8. The bottom of the inner walls on both sides of the U-shaped mounting bracket 2 are symmetrically fixed with clamping mechanisms 3. The underwear fabric is placed on the top of the lower sealing box 8, and the clamping mechanisms 3 are used to clamp and fix the two ends of the underwear fabric. The fixing mechanism 6 is used to match the sealing frame 68 with the sealing groove 11, so that the upper sealing box 67 covers the lower sealing box 8, which has good sealing performance. By starting the air pump 9, the gas is delivered to the inner cavity of the lower sealing box 8 through the air supply pipe 10, so that the flowing gas enters the inner cavity of the upper sealing box 67 through the fabric. The air pressure is detected by the air pressure detector 13, which facilitates the detection of the breathability of the underwear fabric.

[0021] As one implementation method in this embodiment, such as Figure 4 As shown, the fixing mechanism 6 includes a fixing plate 61 fixedly installed on the telescopic end of the cylinder push rod 5. A second moving groove 62 is provided at the bottom of the fixing plate 61. A second motor 63 is fixedly installed on one side of the fixing plate 61. A bidirectional threaded shaft 64 is fixedly connected to the output end of the second motor 63. Second moving blocks 65 are symmetrically threaded at both ends of the bidirectional threaded shaft 64. Insert rods 66 are fixedly connected to the bottom of the two second moving blocks 65 on the side closest to each other. An upper sealing box 67 is provided at the end of the insert rod 66 away from the second moving block 65. Insert holes 69 are symmetrically provided on the top of both sides of the upper sealing box 67. A sealing frame strip 68 is fixedly connected to the bottom of the upper sealing box 67. A pressure detector is fixedly installed at the top of the inner cavity of the upper sealing box 67. The pressure detector 13 has a bidirectional threaded shaft 64 that extends through the fixed plate 61 into the interior of the second moving groove 62. The end of the bidirectional threaded shaft 64 away from the second motor 63 is connected to the bearing of the fixed plate 61. The insertion rod 66 matches the insertion hole 69. Slider 12 is symmetrically fixedly connected to both sides of the fixed plate 61. The end of the slider 12 away from the fixed plate 61 forms a sliding connection structure with the sliding groove 7. By starting the second motor 63, the second motor 63 drives the two second moving blocks 65 to move towards the middle along the second moving groove 62, thereby driving the two insertion rods 66 to move towards the middle and insert into the interior of the insertion hole 69. This facilitates the quick installation of the upper sealing box 67, and the installation and disassembly are convenient, making it easy to inspect and maintain the pressure detector 13.

[0022] As one implementation method in this embodiment, such as Figure 2-3 As shown, the clamping mechanism 3 includes a U-shaped mounting plate 31 fixedly connected to the bottom of the inner wall of the U-shaped mounting bracket 2. A first moving groove 32 is provided on the side of the U-shaped mounting plate 31 away from the U-shaped mounting bracket 2. A first motor 33 is fixedly mounted on the top of the U-shaped mounting plate 31. A reciprocating screw 34 is fixedly connected to the output end of the first motor 33. A first moving block 35 is threadedly connected to the end of the reciprocating screw 34 near the first motor 33. A fixed rod 36 is fixedly connected to one side of the bottom of the first moving block 35. A moving clamping plate 37 is fixedly connected to the bottom of the fixed rod 36. A fixed clamping plate 38 is fixedly connected to the bottom of the mounting frame of the U-shaped mounting plate 31. The reciprocating screw 34 extends through the U-shaped mounting plate 31 to the first moving block 35. Inside the moving groove 32, the end of the reciprocating screw 34 away from the first motor 33 is connected to the bearing of the U-shaped mounting plate 31. The sealing frame strip 68 matches the sealing groove 11. By starting the first motor 33, the first motor 33 drives the reciprocating screw 34 to rotate. The reciprocating screw 34 drives the first moving block 35 to move downward along the first moving groove 32, thereby driving the moving clamp 37 fixed at the bottom of the fixed rod 36 to move towards the fixed clamp 38. This facilitates clamping and fixing of underwear fabrics of different sizes and thicknesses, making it easier for the upper sealing box 67 and the lower sealing box 8 to close, and improving the sealing performance. This also facilitates subsequent inspection of the breathability of the underwear fabric, making the test results more accurate.

[0023] Working principle: When using this device to test the breathability of underwear fabric, firstly, the underwear fabric is placed on top of the lower sealing box 8. Then, the first motor 33 is started, which drives the reciprocating screw 34 to rotate. The reciprocating screw 34 drives the first moving block 35 to move downward along the first moving groove 32, thereby moving the moving clamp 37 fixed at the bottom of the fixing rod 36 towards the fixing clamp 38. This facilitates clamping and fixing of underwear fabrics of different sizes and thicknesses. Then, the cylinder 4 is started, which drives the cylinder push rod 5 to extend and retract, causing the slider 12 to move downward along the sliding groove 7, thereby causing the fixing plate 61 to descend. This causes the upper sealing box 67 to move downward and cover the top of the lower sealing box 8. The sealing groove 11 and the sealing frame strip are then connected. The 68 components are matched to improve the sealing of the cover. By starting the air pump 9, gas is delivered to the inner cavity of the lower sealing box 8 through the air supply pipe 10. The flowing gas enters the inner cavity of the upper sealing box 67 through the fabric. The air pressure is then detected by the air pressure detector 13, which facilitates the quick detection of the breathability of the underwear fabric. When the air pressure detector 13 needs to be inspected or maintained, the second motor 63 is started. The second motor 63 drives the two second moving blocks 65 to move to the sides along the second moving groove 62, which in turn drives the two insert rods 66 to move to the sides, so that the insert rods 66 disengage from the insertion hole 69. This facilitates the quick disassembly of the upper sealing box 67. The installation and disassembly are convenient, making it easy to inspect and maintain the air pressure detector 13.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
