Description

Technical Field

[0001] The utility model relates to the field of fabric testing, in particular to a fabric hydrostatic pressure tester. Background Art

[0002] The fabric hydrostatic pressure test is designed to demonstrate the resistance water encounters when penetrating a fabric through the hydrostatic pressure it can withstand. Under standard atmospheric conditions, a continuously increasing water pressure is applied to one side of the specimen until water seeps into three locations. The pressure recorded at this point is the hydrostatic pressure. Generally, the greater the hydrostatic pressure a fabric can withstand, the better its waterproofness or water permeability resistance. When conducting the test, the fabric must first be laid flat on the pressure area and then secured. However, some fabrics are soft and elastic and may not be laid flat on the pressure area. During subsequent securing, the outer side of the fabric is squeezed, causing wrinkles in the middle, which in turn affects the test results.

[0003] After searching, Chinese patent announcement number: CN218974101U discloses a fabric hydrostatic pressure tester, including a machine base, which has a C-shaped structure. An overflow pan and a drive assembly are provided on the machine base, a pressure ring assembly is provided on the drive assembly, the overflow pan is located below the pressure ring assembly, and the pressure ring assembly is used to tightly cover the fabric on the overflow pan. A water receiving pan is provided outside the overflow pan, and a waterproof film is provided on the water receiving pan, and the pressure ring assembly and the overflow pan are wrapped with the waterproof film. This utility model adds a water receiving pan and a waterproof film, and uses the waterproof film to gather water into the water receiving pan, thereby avoiding water splashing caused by fabric expansion and cracking. The waterproof film is fixed by a magnetic ring, which can realize rapid assembly of the waterproof film. A camera is added to perform image recognition and determine the water outlet point through a computer, and automatically record data.

[0004] In the above technology, although there are certain improvements through its designed structure, when it is used, the fabric is directly laid flat on the overflow tray and then fixed with a pressure ring. Some fabrics may have certain wrinkles on the surface due to improper storage or previous processing. Failure to flatten the wrinkles may cause deviations in the test results and reduce the test effect. Therefore, a fabric hydrostatic pressure tester is proposed to solve the above problem.

Since it is a prior art, it will not be described in detail in this case. The upper surface of the test device 1 is provided with a driving rod 2, and the protective shell 31 can be controlled to move up or down by rotating the driving rod 2. The lower surface of the driving rod 2 is provided with a fixing component, and the inner wall of the fixing component is provided with a cleaning component. The fixing component includes a protective shell 31, and the protective shell 31 is made of a transparent material. It is made to facilitate observation of the test situation. The protective shell 31 is fixedly connected to the lower surface of the driving rod 2. The right surface of the bottom end of the protective shell 31 is fixedly connected to the fixed block 36. The front surface of the fixed block 36 is rotatably connected to the round rod 37. When the protective shell 31 moves downward, the trowel plate 32 contacts the fabric. At this time, the protective shell 31 is continued to be controlled to descend. The trowel plate 32 will rotate with the center of the round rod 37 as the origin to smooth the fabric and ensure the test effect. The outer wall of the round rod 37 is fixedly connected to the trowel plate 32, and the top of the trowel plate 32 slides on the inner wall of the fixed block 36.

[0025] Reference Figure 1 - Figure 3 The cleaning component includes a movable plate 41, which is adapted to the inner wall of the protective shell 31 to ensure the stability of movement. The movable plate 41 is slidably connected to the inner wall of the protective shell 31, and the outer wall of the bottom end of the protective shell 31 is fixedly connected with a Velcro 1 45. The outer wall of the Velcro 1 45 contacts the Velcro 2 46. The Velcro 1 45 and the Velcro 2 46 can adhere to each other, so that the cleaning cotton strip 43 can be quickly disassembled and installed. The outer wall of the Velcro 2 46 is fixedly connected with the cleaning cotton strip 43. The cleaning cotton strip 43 is made of soft and absorbent material to ensure the cleaning effect. The outer wall of the cleaning cotton strip 43 slides on the inner wall of the protective shell 31, and the right surface of the cleaning cotton strip 43 is fixedly connected with a connecting block 47.

[0026] Reference Figure 2 、 Figure 4The right end of the lower surface of the trowel plate 32 is fixedly connected with a trowel block 33, and the inner wall of the bottom end of the trowel plate 32 is rotatably connected with a roller 34. The fabric is smoothed and stretched by the trowel block 33. When the protective shell 31 is fixed, the fabric may be recovered. The roller 34 can ensure that the fabric can be recovered smoothly and the stability of the fixation is ensured. The outer wall of the front end of the round rod 37 is sleeved with a torsion spring 38. The torsion spring 38 ensures that the trowel plate 32 can be quickly reset when the protective shell 31 is raised through its own elasticity, and the trowel plate 32 can be quickly reset through its elasticity. 2 has a certain inclination toward the outside at its initial position. One end of a torsion spring 38 is fixedly connected to the front surface of the fixed block 36, and the other end of the torsion spring 38 is fixedly connected to the rear surface of the round rod 37. There are multiple groups of trowel plates 32, fixed blocks 36, and round rods 37, and the multiple groups of trowel plates 32, fixed blocks 36, and round rods 37 are arranged in a circular array with the center of the protective shell 31 as the origin. Multiple groups of trowel plates 32, fixed blocks 36, and round rods 37 are set to ensure that the fabric can be smoothly smoothed and stretched. The trowel block 33 is set to be made of rubber.

[0027] Reference Figure 2 - Figure 3 The cleaning component also includes a threaded rod 42. The threaded rod 42 is a prior art. It is a rod-shaped structure with a threaded outer wall. When it rotates, the structure threadedly connected to its outer wall will move linearly. At the same time, it has the characteristics of self-locking up and down to ensure the stability of the structural connection. The threaded rod 42 passes through and is rotatably connected to the right end of the upper surface of the protective shell 31. The outer wall of the threaded rod 42 is threadedly connected to a slider 44. The slider 44 is adapted to the slide groove 35 to ensure the stability of the movement of the movable plate 41. The left surface of the slider 44 is fixedly connected to the top of the right surface of the movable plate 41. The right side of the inner wall of the protective shell 31 is provided with a slide groove 35, and the slider 44 is slidably connected to the inner wall of the slide groove 35.

[0028] Working principle: When using the test equipment 1 to test the fabric, the support is placed on the test table and under the protective shell 31. At this time, the protective shell 31 is controlled to move up or down by rotating the driving rod 2. When the protective shell 31 moves downward, the smoothing block 33 fixed on the lower surface of the trowel plate 32 will contact the fabric, and the protective shell 31 will continue to be controlled to descend. The trowel plate 32 will rotate with the center of the round rod 37 as the origin, and the round rod 37 will drive the torsion spring 38 to twist and deform. At the same time, the fabric will be stretched out under the action of the smoothing block 33 until the rotating trowel plate 32 makes the smoothing block 33 no longer contact the fabric. At this time, the roller 34 will contact the fabric, so that when the protective shell 31 descends to fix the stretched fabric, the fabric can be smoothly recovered, which improves practicality. When the test is completed and the protective shell 31 is retracted, the trowel plate 32 will be reset by the elasticity of the torsion spring 38.

[0029] When it is necessary to clean the inner wall of the protective shell 31, the threaded rod 42 can be rotated. Since its outer wall is threadedly connected to the slider 44, the slider 44 is fixedly connected to the top of the right surface of the movable plate 41, and the slider 44 is slidably connected to the slide groove 35 opened on the right side of the inner wall of the protective shell 31, rotating the threaded rod 42 will cause the slider 44 to drive the movable plate 41 to move stably along the inner wall of the protective shell 31, so that the movable plate 41 can mobilize the cleaning cotton strip 43 to move and clean the inner wall of the protective shell 31.

[0030] In addition, the Velcro 1 45 and the Velcro 2 46 fixedly connected to the outer wall of the bottom end of the protective shell 31 are adhered to each other, and the cleaning cotton strip 43 fixedly connected to the outer wall of the Velcro 2 46 is made of soft water-absorbing material, which can clean the fabric during the movement of the protective shell 31, and the Velcro connection method enables the cleaning cotton strip 43 to be quickly disassembled and installed.
