Description

Technical Field

[0001] This utility model relates to the field of textile material performance testing technology, and in particular to a water permeability testing device for outdoor sofa fabrics. Background Technology

[0002] With the rapid development of the outdoor functional textile market, the research and development of camping equipment and special protective clothing requires quantitative treatment of the waterproof and permeability performance of sofa fabrics, which requires the use of water permeability testing devices. In practical use, similar permeability testing devices still have many defects. For example, traditional permeability testing devices rely on a single layer of rubber ring for sealing, which is prone to leakage when there are large temperature differences outdoors or when the fabric is wrinkled and uneven. At the same time, the traditional threaded locking method of permeability testing devices requires multiple rotations to take effect and it is difficult to quantify and control the pressure. Therefore, it is necessary to design a permeability testing device for outdoor fabrics. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a device for testing the water permeability of outdoor sofa fabrics.

[0004] This utility model is achieved using the following technical solution: a water permeability testing device for outdoor sofa fabric, comprising a testing component, the testing component including a testing device body, a mounting bracket fixedly connected to the top of the testing device body, a positioning bolt rotatably connected inside the mounting bracket, and a sealing ring fixedly connected to the inner wall of the testing device body, and further comprising: A sealing assembly, comprising a mounting plate fixedly connected to the bottom of a positioning bolt, wherein a sealing ring and a top sealing plug are fixedly connected to the bottom of the mounting plate via a connecting rod; A fixing assembly, the fixing assembly including a piston slidably mounted inside a positioning bolt, the bottom of the piston being connected to a locking seat via a connecting bracket.

[0005] As a further improvement to the above solution, a bottom sealing plug is fixedly connected inside the sealing ring, and a locking rod is slidably installed inside the sealing ring.

[0006] The above technical solution significantly improves the airtightness of the sofa fabric and the testing device by fixing the bottom sealing plug inside the sealing ring and forming a symmetrical redundant sealing structure with the top sealing plug. The sliding installation design of the locking rod provides a precise positioning reference for the subsequent engagement and locking of the locking seat, ensuring the reliability of the mechanical linkage process.

[0007] As a further improvement to the above solution, a connecting rod is fixedly connected to the bottom of the mounting plate, and a sealing ring is fixedly connected to the bottom of the connecting rod.

[0008] By using the above technical solution, a stable pressure frame is formed by vertically fixing the connecting rod to the bottom of the mounting plate and rigidly connecting it with the sealing ring. This structure can convert the rotational movement of the positioning bolt into uniform downward pressure, so that the compression deformation between the sealing ring and the sealing ring is consistent, avoiding sealing failure caused by local stress concentration.

[0009] As a further improvement to the above solution, the sealing ring and the sealing ring are matched, and a top sealing plug is fixedly connected to the inner wall of the sealing ring.

[0010] By using the above technical solution, a double dynamic sealing barrier is constructed by making the cross-sectional shape of the sealing ring and the sealing ring perfectly match, and by adding a top sealing plug to the inner wall of the sealing ring. This nested fit not only enhances the fit of the contact surfaces, but also automatically compensates for the tiny gaps caused by the difference in fabric thickness during the test.

[0011] As a further improvement to the above solution, the top sealing plug and the bottom sealing plug are matched, and the positioning bolt has an internal movable groove.

[0012] The above technical solution provides a guide space for the axial sliding of the piston by opening a movable groove inside the positioning bolt. The size matching design of the top sealing plug and the bottom sealing plug ensures that they can deform synchronously under pressure, eliminating the "off-center leakage" problem that is easy to occur in traditional single-point seals.

[0013] As a further improvement to the above solution, a piston is slidably installed inside the movable groove, and an installation rod is fixedly connected to the bottom of the piston.

[0014] As a further improvement to the above solution, a mounting base is fixedly connected to the bottom of the mounting rod, and a connecting frame is rotatably connected to the outer surface of the mounting base.

[0015] As a further improvement to the above solution, the side of the connecting bracket away from the mounting base is rotatably connected to the top of the rotating rod, and the rotating rod is rotatably connected to the inside of the sealing ring.

[0016] By using the above technical solution, a closed-loop torque transmission system is formed by rotating the top of the rotating rod to the connecting frame and embedding the bottom into the sealing ring. When the mounting rod is pressed down, the rotating rod generates a radial contraction force around the sealing ring, which forces the locking seat to slide along the surface of the locking rod, thus achieving self-locking fastening.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention drives the positioning bolt to move axially along the mounting frame by manually rotating it, which in turn causes the bottom connecting rod and sealing ring to descend synchronously, making the fabric of the sofa fit tightly against the surface of the sealing ring. This structure achieves adaptive compression through mechanical transmission, ensuring that the fabric and the sealing interface form an initial contact pressure. At the same time, the bidirectional squeezing action of the top sealing plug and the bottom sealing plug creates a redundant sealing path, significantly improving the airtightness of the contact surface and effectively preventing the leakage of test liquid.

[0018] When the mounting rod descends along the movable groove under control, the piston generates a damping buffer force to avoid impact loads and ensure smooth movement. During this process, the connecting frame inside the mounting base drives the rotating rod to rotate, forcing the locking seat to deflect around a fixed axis and engage with the locking rod to lock. This linkage mechanism converts the vertical pressure into a rotational locking torque, causing continuous and uniform compression deformation between the sealing ring and the sealing ring, ultimately forming a stable and reliable static seal and completely eliminating the risk of loosening caused by vibration or pressure fluctuations.

[0022] Example: Please combine Figure 1-6 This embodiment provides a water permeability testing device for outdoor sofa fabric, including a testing component 1. The testing component 1 includes a testing device body 101, a mounting bracket 102 fixedly connected to the top of the testing device body 101, a positioning bolt 103 rotatably connected inside the mounting bracket 102, and a sealing ring 104 fixedly connected to the inner wall of the testing device body 101. It also includes: The sealing assembly 2 includes a mounting plate 201 fixedly connected to the bottom of the positioning bolt 103. The bottom of the mounting plate 201 is fixedly connected to a sealing ring 203 and a top sealing plug 204 via a connecting rod 202. The fixing component 3 includes a piston 301 that is slidably installed inside the positioning bolt 103, and the bottom of the piston 301 is connected to a locking seat 306 via a connecting bracket 304.

[0023] A bottom sealing plug 105 is fixedly connected inside the sealing ring 104, and a locking rod 106 is slidably installed inside the sealing ring 104.

[0024] A connecting rod 202 is fixedly connected to the bottom of the mounting plate 201, and a sealing ring 203 is fixedly connected to the bottom of the connecting rod 202.

[0025] The sealing ring 203 is matched with the sealing ring 104, and the top sealing plug 204 is fixedly connected to the inner wall of the sealing ring 203.

[0026] The top sealing plug 204 and the bottom sealing plug 105 are matched, and the positioning bolt 103 has a movable groove 205 inside.

[0027] A piston 301 is slidably installed inside the movable groove 205, and an installation rod 302 is fixedly connected to the bottom of the piston 301.

[0028] The bottom of the mounting rod 302 is fixedly connected to the mounting base 303, and the outer surface of the mounting base 303 is rotatably connected to the connecting bracket 304.

[0029] The side of the connecting bracket 304 away from the mounting base 303 is rotatably connected to the top of the rotating rod 305, and the rotating rod 305 is rotatably connected to the inside of the sealing ring 203.

[0030] As the mounting rod 302 descends, the connecting bracket 304 inside the mounting base 303 drives the rotating rod 305 to rotate within the sealing ring 203, and the locking seat 306 is fastened to the surface of the locking rod 106, ensuring the locking between the sealing ring 203 and the sealing ring 104, thereby ensuring the locking and sealing performance between the sealing ring 203 and the sealing ring 104.

[0031] The implementation principle of the water permeability testing device for outdoor sofa fabric in this embodiment is as follows: The positioning bolt 103 is manually held and rotated within the mounting frame 102 to ensure its smooth descent. A sealing ring 203 is fixedly connected to the bottom of the positioning bolt 103 via a connecting rod 202. The sofa fabric is then placed on the surface of the sealing ring 104. As the sealing ring 203 descends, it seals the sofa fabric. Simultaneously, the bottom sealing plug 105 and the top sealing plug 204 further ensure the sealing performance. After the initial sealing is completed, the mounting rod 302 is manually driven to descend under the limit of the movable groove 205. The piston 301 ensures that the mounting rod 302 will not descend directly due to gravity. As the mounting rod 302 descends, the connecting bracket 304 inside the mounting base 303 drives the rotating rod 305 to rotate inside the sealing ring 203, and the locking seat 306 is fastened to the surface of the locking rod 106 to ensure the locking between the sealing ring 203 and the sealing ring 104, thereby ensuring the locking and sealing performance between the sealing ring 203 and the sealing ring 104.
