[0002] Thermal resistance testing of clothing fabrics plays a crucial role in the apparel industry. Its main purpose is to scientifically and accurately quantify the thermal insulation performance of fabrics, providing key parameters for clothing design and helping designers create clothing products that are both fashionable and have good warmth or heat dissipation functions; to provide data support for optimizing clothing functions, enabling clothing to better adapt to different scenarios and user needs; to promote the standardization process in the industry, ensuring that the quality of clothing products on the market meets unified standards; and to provide consumers with scientific basis when choosing clothing, helping them select products that are more suitable for their own needs.

[0003] As a special type of functional clothing, the thermal resistance testing of diving suits is of paramount importance. Divers face complex and ever-changing environments underwater, where water temperatures are often low and decrease further with depth, while water pressure increases continuously. In this context, diving suits become crucial equipment for divers to protect themselves from low temperatures and ensure their safety. Thermal resistance testing of diving suits precisely quantifies the insulation performance of the materials used, ensuring that the suit provides effective low-temperature protection for divers at different depths and water temperatures. This prevents serious consequences such as hypothermia caused by low body temperature, thus guaranteeing the smooth progress of diving operations and the safety of divers.

[0004] However, the existing thermal resistance testing equipment for diving suit fabrics on the market has certain limitations and cannot meet the needs of accurately testing the thermal resistance of diving suit fabrics under different underwater pressure environments. This results in discrepancies between the test results and actual usage conditions, making it difficult to accurately assess the thermal insulation performance of diving suit fabrics in actual diving environments.

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings. Here, the illustrative embodiments and descriptions of this utility model are used to explain the present utility model, but are not intended to limit the present utility model.

[0028] refer to Figures 1 to 6 ,like Figure 1 , Figure 2 As shown, this embodiment provides an invasive thermal resistance tester for diving suit fabric, including a base 1, a housing 2, a lifting mechanism 3, a connecting assembly, a testing mechanism 5, and a sample container 6. The base 1 has a mounting groove 14 on its top and a pressure regulating valve 15 on its outer wall. The housing 2 is mounted on the base 1, and its front wall has a display screen 21 and a pair of control buttons 22 for easy operation and data display. The lifting mechanism 3 includes a cylinder assembly, a drive assembly, and a lifting platform 35, which is mounted at the bottom of the drive assembly. The connecting assembly is mounted at the bottom of the lifting platform 35 and includes an upper connecting plate 41 and a U-shaped placement hook 42, with the U-shaped placement hook 42 fixedly connected to the center of the bottom of the upper connecting plate 41. The testing mechanism 5 is located within the mounting groove 14 and includes a test cylinder assembly, a pressure regulating head 55, a heating coil 56, and a water inlet 57. The sample container 6 is suspended on the U-shaped placement hook 42, and the lifting mechanism 3 drives the sample container 6 into the test cylinder assembly to measure the thermal resistance performance of the diving suit fabric contained in the sample container 6.

[0029] In this embodiment, as Figure 6 As shown, the sample container 6 includes a container body 61, a lid 62, and a C-shaped hook 63. The container body 61 is made of glass, which is transparent and durable, allowing for easy observation of the internal conditions. The lid 62 is mounted on the container body 6 and has a second temperature sensor 64 that extends into the inner cavity of the container body 61, enabling real-time monitoring of the internal temperature of the sample container 6. The C-shaped hook 63 is mounted at the top center of the lid 62 and is used to connect with a U-shaped placement hook 42, allowing for the suspension and lifting of the sample container 6.

[0030] In this embodiment, as Figure 7 As shown, the measuring instrument also includes screw 7.

[0031] To be precise, such as Figure 5 As shown, the upper connecting plate 41 is circular, with several protrusions evenly distributed around its outer circumference. Each protrusion has a vertical through hole, allowing screws 7 to pass through for secure connection. The bottom of the upper connecting plate 41 has two concentric sealing rings 44 to ensure a tight seal when connected to the test cylinder assembly, preventing water leakage.

[0032] like Figure 7 As shown, the test tube assembly includes a test tube body 51 with a top opening, a lower connecting plate 52, three inclined tubes 53, and three observation windows 54. The test tube body 51 has a water inlet 57 on its side wall for adding water into the test tube. The lower connecting plate 52 is concentrically fixed to the opening of the test tube body 51. Its outer circumferential protrusion 2 matches the structure of protrusion 1 on the upper connecting plate 41, and protrusion 2 has a countersunk groove that matches the screw 7. The top of the lower connecting plate 52 has a pair of sealing grooves 521 corresponding to the structure of the sealing ring 44, ensuring a tight connection. The three inclined tubes 53 are concentrically obliquely cut through and installed on the outer wall of the test tube body 51. The three observation windows 54 are correspondingly installed at the ends of the inclined tubes 53. The three inclined tubes 53 are distributed at 180°, allowing for multi-angle monitoring and observation of the sample container 6 inside the test tube body 51, enabling timely detection of abnormalities such as leaks.

[0033] like Figure 2 As shown, a switch 11 is provided on the right side of the base 1 to control the power supply of the measuring instrument; a water pipe connector 12 is provided on the rear side, which is connected to the water inlet 57 through a connecting pipe to realize automatic water addition into the test tube body 51.

[0034] Furthermore, such as Figure 4 As shown, the hydraulic cylinder assembly includes positioning pins 312, positioning plates 313, and hydraulic cylinders 311. There are four positioning pins 312, which are symmetrically fixed to the top of the base 1 to provide stable support for the positioning plates 313. The positioning plates 313 are installed on the top of the positioning pins 312, and the end flange of the hydraulic cylinders 311 is fixed to the center of the bottom surface of the positioning plates 313, with the cylinder body extending into the interior of the base 1.

[0035] like Figure 4 As shown, the drive assembly is located inside the housing 2 and includes a top plate 33, a pair of limiting rods 32, and a pair of movable rods 34. The top plate 33 is located at the end of the piston rod of the hydraulic cylinder 311, the limiting rods 32 are symmetrically located at one bottom end of the top plate 33, and the movable rods 34 are symmetrically located at the other bottom end of the top plate 33.

[0036] refer to Figure 4 A pair of limiting grooves 13 are provided on the top of the base 1, corresponding to the positions of the limiting rod 32.

[0037] Before the drive assembly is used, the lifting platform 35 is in the highest position. When in use, the hydraulic cylinder 311 starts to work, driving the top plate 33 to move downward and causing the lifting platform 35 to move downward. The limit rod 32 and the limit groove 13 cooperate to ensure the smoothness and accuracy of the lifting process.

[0038] Specifically, the lifting mechanism 3 causes the lifting platform 35 to lower the upper connecting plate 41 and the sample container 6 until the upper connecting plate 41 and the lower connecting plate 52 are tightly fitted together, and the sealing ring 44 is embedded in the corresponding sealing groove 521, forming a reliable sealing structure to prevent water leakage during the test. At this time, the screw 7 passes through the through hole of the first protrusion of the upper connecting plate 41 and engages with the groove of the second protrusion of the lower connecting plate 52 to lock it, tightly connecting the upper connecting plate 41 to the test cylinder assembly, ensuring the stability of the test environment.

[0039] In this embodiment, as Figure 7 As shown, the testing mechanism 5 also includes a pressure regulating head 55 and a heating coil 56. The pressure regulating head 55 is connected to the pressure regulating valve 15 and extends into the inner cavity of the test cylinder body 51, which can precisely control the pressure inside the test cylinder. The heating coil 56 is arranged around the inner wall of the test cylinder body 51 and adopts a high-frequency induction heating method, which can quickly and evenly heat the water inside the test cylinder body 51, improving the testing efficiency.

[0040] Among them, such as Figure 6 As shown, the upper connecting plate 41 is equipped with a first temperature sensor 43. When the upper connecting plate 41 is attached to the test cylinder assembly, the first temperature sensor 43 extends into the test cylinder body 51 and can monitor the water temperature inside the test cylinder body 51 in real time.

[0041] The specific usage steps are as follows: Place a small sample of the diving suit fabric or the entire suit in the sample container, then suspend the C-shaped hook 63 on the U-shaped placement hook 42 to securely connect the sample container 6 to the lifting platform 35. Press the operation control button 22 with both hands, the hydraulic cylinder 311 starts working and drives the lifting platform 35 downward, so that the sample container 6 is completely flush and tightly against the test cylinder body 51, then tighten the screw 7. Start the water inlet function, water enters the test cylinder body 51 from the water inlet 57, and the system automatically stops adding water after the water level reaches the set value. Press the switch 11 on the right side of the base 1, the first temperature sensor 43 and the second temperature sensor 64 monitor the temperature difference between the inside and outside of the sample container 6, and use the heating coil 56 to control the water temperature in the test cylinder body 51 between 10℃ and 15℃. At the same time, control the pressure regulating valve 15 to control the pressure at 1 bar and 6 bar absolute pressure respectively to simulate the pressure environment at different depths of water. Then, start heating the water in the test cylinder body 51 and stabilize the temperature between 30℃ and 45℃. After stabilizing for 15 minutes, the temperature difference between the sample barrel 6 and the test barrel body 51 is observed through the display screen 21. This temperature difference data can be used to calculate the thermal resistance performance of the diving suit fabric. Simultaneously, water leakage is checked inside the sample barrel 6 through different observation windows 54 to ensure the accuracy of the test results. After the test is completed, the hydraulic cylinder 311 operates, causing the lifting platform 35 to rise, removing the sample barrel 6, and draining the water to complete the test.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. For those skilled in the art, various modifications and variations can be made to the embodiments of the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
