Description

Technical Field

[0001] This utility model relates to the field of fabric water permeability testing technology, and in particular to a transparent cover for splash protection. Background Technology

[0002] In existing fabric water permeability testing processes, it is usually necessary to apply a certain pressure of water flow to the fabric sample to simulate water permeation situations that may be encountered in actual use environments, thereby evaluating the waterproof performance of the fabric. In such tests, in order to prevent water splashing and ensure the stability and safety of the test environment, a protective structure such as a transparent cover is usually set up in the test area.

[0003] However, most existing transparent covers are fixed structures, which means that the entire transparent cover needs to be disassembled when changing fabric samples, making the operation cumbersome.

[0004] Furthermore, during testing, the water is typically sprayed from bottom to top, creating an impact force on the bottom of the transparent cover. If the cover is not securely fixed, it can easily shift or even loosen, affecting the accuracy of the test results and potentially causing liquid leakage, thus compromising equipment safety. Additionally, after the test, water can easily accumulate inside the transparent cover; if not drained promptly, this can negatively impact test accuracy. Utility Model Content

[0005] This utility model provides a transparent cover for splash protection, including a first transparent cover and a second transparent cover that cooperate with each other. The upper ends of the first transparent cover and the second transparent cover are fixedly connected to a long block. The top of the long block is provided with a positioning mechanism, which is detachably fixed inside the connecting components. When the two connecting components are attached to each other, the first transparent cover and the second transparent cover are driven to close synchronously, forming a sealed structure for the test area of ​​the fabric water permeability tester, preventing liquid splashing during the test.

[0006] Preferably, the connecting assembly includes two opposing semicircular sleeves, which are adapted to the outer periphery of the lifting rod on the fabric permeability tester, forming an annular wrapping structure for fixed support. The lower end of each semicircular sleeve is connected to a set of connecting plates, and the two sets of connecting plates are connected by bolts.

[0007] Preferably, both sets of connecting plates have elongated grooves, and symmetrical positioning grooves are formed on the two side walls inside the elongated grooves.

[0008] Preferably, the positioning mechanism includes a fixed rod fixed to the upper end of the long block, an installation groove is opened at the end of the fixed rod, a bidirectional lead screw is rotatably installed inside the installation groove, and the two ends of the bidirectional lead screw are respectively threaded to positioning blocks, and the positioning blocks slide in the side groove opened on the side wall of the fixed rod.

[0009] Preferably, a bevel gear one is connected to the middle of the bidirectional lead screw, and a rotating rod is rotatably installed in the solid part inside the mounting groove. The lower end of the rotating rod is connected to a bevel gear two, and the bevel gear one and the bevel gear two mesh with each other.

[0010] Preferably, the positioning block engages with the positioning slot.

[0011] Preferably, positioning sleeve one and positioning sleeve two are fixedly mounted on the lifting rod of the fabric permeability tester. Positioning sleeve one and positioning sleeve two are fixed by bolts, and a semi-circular sleeve is located between positioning sleeve one and positioning sleeve two.

[0012] Preferably, both the first and second transparent covers have exhaust holes at their upper ends, and a one-way valve is installed inside the exhaust hole.

[0013] Preferably, the first and second transparent covers are made of high-transparency polycarbonate. A sealing strip is provided on one side of the first transparent cover, and a sealing groove is provided on one side of the second transparent cover. The sealing strip and the sealing groove are interlocked.

[0014] Preferably, a drain pipe is connected to the water inlet on the lower side of the transparent cover.

[0015] This utility model provides a transparent cover for preventing splashing, which, compared with the prior art, has the following advantages:

[0016] 1. This utility model limits and fixes the two sets of semi-circular sleeves in their fitted state by setting positioning sleeve one and positioning sleeve two. With the snap-fit ​​structure of positioning block and positioning groove, transparent cover one and transparent cover two are stably installed between two sets of connecting plates. When the lifting rod of the fabric water permeability tester rises, it can drive transparent cover one and transparent cover two to move upward synchronously, thereby providing sufficient space for placing fabric samples. There is no need to disassemble the entire transparent cover device every time the sample is changed, making the operation more convenient. At the same time, the structure retains good disassembly, which facilitates the daily maintenance and component replacement of the device, improving the flexibility and practicality of use.

[0017] 2. This utility model uses positioning sleeve one and positioning sleeve two to axially limit the semi-circular sleeve, which enhances the structural stability of transparent cover one and transparent cover two when subjected to the impact of water flow from bottom to top, effectively preventing the transparent cover from shifting or loosening due to water pressure. At the same time, the design of the sealing strip and sealing groove further improves the sealing performance of the closed area of ​​the transparent cover, ensuring that the liquid will not leak out during the test. The water can be discharged in time through the drain pipe, avoiding the accumulation of too much water in the transparent cover device, which would affect the test results.

[0029] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0030] Please refer to Figures 1-8This utility model provides a transparent cover for splash protection, including a transparent cover 1 and a transparent cover 2 that cooperate with each other. The transparent cover 1 and the transparent cover 2 are made of highly transparent polycarbonate and have good light transmittance and structural strength.

[0031] like Figure 3 As shown, a sealing strip 22 is fixedly installed on one side of the transparent cover 1, and a sealing groove 21 adapted to the sealing strip 22 is opened on the corresponding side of the transparent cover 2. The two are connected in a sealed manner by plugging, thereby forming a closed test environment.

[0032] A water inlet is provided on the lower side of the transparent cover 1, and a drain pipe 3 is connected to the water inlet to quickly drain the water inside the transparent cover 1 and the transparent cover 2, so as to prevent excessive water flow from affecting the test.

[0033] Both transparent cover 1 and transparent cover 2 are fixedly connected to the upper ends of a long block 12. The top of the long block 12 is provided with a positioning mechanism for fixing transparent cover 1 and transparent cover 2 as a whole inside the connecting component.

[0034] The connecting assembly includes two opposing semicircular sleeves 9. The inner walls of the two semicircular sleeves 9 are adapted to the outer periphery of the lifting rod on the fabric permeability tester. When the two are closed, they form a ring-shaped wrapping structure for wrapping and supporting the lifting rod. The lower end of each semicircular sleeve 9 is fixedly connected to a set of connecting plates 8. The two sets of connecting plates 8 are connected and fastened by bolts.

[0035] The fabric permeability tester has two sets of water outlets in the test area. The upper end of the fabric permeability tester has a threaded screw, and the lower end of the screw is rotatably connected to a lifting rod. The lower end of the lifting rod is fixedly connected to a pressure block for fixing the fabric. The upper end of the screw is fixedly connected to a handwheel. Rotating the handwheel allows the screw to move upward with the lifting rod and the pressure block. At this time, the fabric to be tested can be placed in the test area, and the pressure block is used to fix the fabric. The fabric covers the water outlet, and water is sprayed from the outlet from bottom to top. The water needs to be broken through the fabric to complete the permeability test. To prevent water splashing, transparent cover 1 and transparent cover 2 are used to seal the test area.

[0036] Long grooves 10 are provided on the two sets of connecting plates 8. Positioning grooves 11 are symmetrically provided on the two side walls of the long grooves 10, which are used to cooperate with the positioning mechanism to achieve stable fixation of transparent cover 1 and transparent cover 2.

[0037] like Figure 8 As shown, the positioning mechanism is located on the top of the long block 12, including a fixing rod 13 fixed on the long block 12. The end of the fixing rod 13 is provided with a mounting groove 14, and a bidirectional lead screw 15 is rotatably installed inside the mounting groove 14.

[0038] The two ends of the bidirectional lead screw 15 are respectively threaded with positioning blocks 17. The positioning blocks 17 can slide in the side grooves 16 opened on the side wall of the fixed rod 13. The middle part of the bidirectional lead screw 15 is connected to a bevel gear 18. The solid part inside the mounting groove 14 is rotatably provided with a rotating rod 19. The lower end of the rotating rod 19 is connected to a bevel gear 20. The bevel gear 18 and the bevel gear 20 mesh with each other. When the rotating rod 19 is rotated, the bevel gear 20 drives the bevel gear 18 to rotate, which in turn drives the bidirectional lead screw 15 to rotate, so that the positioning blocks 17 move to both sides along the side grooves 16, thereby engaging with the positioning grooves 11 on the connecting plate 8, realizing the rapid positioning and fixing of the transparent cover 1 or the transparent cover 2.

[0039] Positioning sleeve 1 6 and positioning sleeve 2 7 are fixedly sleeved on the lifting rod of the fabric permeability tester. The two are connected by bolts and are used to axially limit the two sets of semi-circular sleeves 9 in the fit state. The semi-circular sleeves 9 are located between positioning sleeve 1 6 and positioning sleeve 2 7. This structure can ensure the stable installation of the entire connecting component on the lifting rod.

[0040] When the lifting rod rises, the connecting assembly rises accordingly, causing transparent cover 1 and transparent cover 2 to move upward synchronously, thereby opening the test area. This facilitates the placement or replacement of fabric samples without disassembling the entire transparent cover device, thus improving operational efficiency.

[0041] like Figure 3 As shown, both transparent cover 1 and transparent cover 2 have exhaust holes 4 at their upper ends. A one-way valve 5 is installed in the exhaust hole 4 to maintain the air pressure balance inside the transparent cover during the test and prevent the transparent cover 1 and transparent cover 2 from deforming due to air pressure changes.

[0042] The insertion and engagement of the sealing strip 22 and the sealing groove 21 further ensures the sealing performance of the closed area of ​​the transparent cover 1 and the transparent cover 2, preventing liquid leakage during the test and ensuring the cleanliness and safety of the test environment.

[0043] In summary, by using positioning sleeve 1 6 and positioning sleeve 2 7 to limit and fix the semi-circular sleeve 9, and by combining the snap-fit ​​between positioning block 17 and positioning groove 11, transparent cover 1 and transparent cover 2 can be stably installed in the connecting assembly and can be raised and lowered synchronously with the lifting rod, which facilitates the placement of fabric samples. Furthermore, transparent cover 1 and transparent cover 2 can also be used stably when the fabric water permeability tester sprays water onto the fabric from bottom to top.

[0044] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
