Description

Technical Field

[0001] The present invention relates to the technical field of water resistance detection devices for interior wall decoration materials, in particular to a water resistance detection device for interior wall decoration materials. Background Art

[0002] Interior wall decoration materials are various materials used for interior wall decoration, mainly including paint, wallpaper, stone, ceramic tile, wood, etc. Interior wall decoration materials need to have good waterproof performance to prevent corrosion, mildew, deformation and other problems caused by water penetration, thereby improving the service life and quality of the decoration materials. Therefore, a water resistance testing device for interior wall decoration materials will be used to test the waterproof performance of interior wall decoration materials, so as to facilitate the subsequent waterproofing of the interior wall decoration materials.

[0003] Patent announcement number CN220961131U discloses an interior decoration material performance detector, including a detection box, two fixing frames are provided at both ends of the detection box, and a driving motor is provided on the top of the two fixing frames. The output end of the driving motor passes through the through hole opened at the top of the fixing frame and is connected to a rotating structure that drives the cover plate to move up and down. The top of the detection box is also provided with a fixing frame, and a first sealing ring is provided inside the fixing frame. The top of the detection box is located in the first sealing ring and a cavity is opened. A humidity sensor is provided in the cavity. By arranging two rotating structures at both ends of the detection box, the rotating structure drives the cover plate to move up and down, so that the second sealing ring at the bottom of the cover plate fits with the material placed on the top of the first sealing ring, and drives the hydraulic cylinder to make the circular piston plate push water downward to the material, thereby accelerating the detection speed of the material and improving the detection efficiency.

[0004] Regarding the above-mentioned related schemes, the hydraulic cylinder causes the circular piston plate to push water downward toward the material. The circular piston plate generates a certain pressure on the water to promote water penetration, but it can only simulate the test environment of the water in a static state or a certain pressure state, as well as the detection effect on the material. It cannot change the pressure state and water flow impact at the same time, and has certain simulation limitations, resulting in incomplete and inaccurate test results of water resistance. For this reason, we propose a water resistance detection device for interior wall decoration materials. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This device for testing the water resistance of interior wall decoration materials uses a rotating shaft that drives paddles one and two to rotate via a rotating trough and guide rods as the pressure plate moves downward, stirring the water. Because the effect of static water on material samples differs from that under dynamic conditions, stirring the water increases the contact area between the water and the sample surface, increasing the water's penetration rate and shortening the testing time.

This simulates different testing environments and increases the impact force of water on the surface of the material sample. Furthermore, the distance between paddles No. 1 and No. 2 allows for water flow, reducing rotational resistance, optimizing the testing environment, and ensuring the stability and reliability of test results.

[0019] 3. The device for testing the water resistance of interior wall decoration materials drives the connecting frame to rise by rising the top plate, thereby operating the pushing mechanism. When the top plate drives the cover plate to separate from the supporting frame, the pushing mechanism pushes the material sample out, thereby improving the convenience of the device for testing the water resistance of interior wall decoration materials.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-Figure 3 、 Figure 5 、 Figure 7 and Figure 12-15 The present invention provides a technical solution: a device for detecting the water resistance of interior wall decoration materials, comprising a detection box 1 and a pressing plate 18, wherein the four corners of the surface of the detection box 1 are connected to a top plate 3 through an electric lifting rod 2, a water injection cylinder 5 is fixed to the lower surface of the top plate 3, a hydraulic cylinder 7 is installed on the top of the top plate 3, the pressing plate 18 is fixedly connected to the output end of the hydraulic cylinder 7 located in the inner cavity of the water injection cylinder 5, the water injection cylinder 5 is symmetrically arranged below the top plate 3, a conduit 11 is fixedly connected between the two water injection cylinders 5, the middle part of the conduit 11 is connected to a water inlet hose 12, and the water inlet hose 12 passes through the inner side of the top plate 3, and the bottom end of the water injection cylinder 5 away from the conduit 11 is connected to a water outlet hose 22.

[0039] This is a device for testing the water resistance of interior wall decoration materials. The electric lifting rod 2 is used for the lifting operation of the top plate 3. The electric lifting rod 2 drives the top plate 3 to move up and down, so that the top plate 3 drives the water injection cylinder 5 and the cover plate 10 to separate from the support frame 4, which is convenient for testing and taking and placing interior wall decoration material samples. The water inlet hose 12 can be connected to an external water supply device to transport water into the conduit 11 and divert it into the two water injection cylinders 5. The hydraulic cylinder 7 pushes the pressure plate 18 downward to generate a certain pressure, pushing the water pressure to the material sample on the support frame 4, accelerating the penetration speed and improving the detection efficiency. After the detection is completed, the water outlet hose 22 can be driven by the external water suction device to discharge the water inside the water injection cylinder 5. After the water is discharged, the cover plate 10 is separated from the support frame 4. This is the content of the existing technology.

[0040] See also Figure 1-Figure 3 and Figures 5-10 A sleeve 15 is fixedly sleeved on the inner wall of the water injection cylinder 5, and a rotation groove 19 is opened on the inner wall of the sleeve 15. Guide rods 17 are fixedly connected to the outer walls of both sides of the rotating shaft 16. The guide rods 17 and the rotating groove 19 are slidingly connected. The rotating shaft 16 is installed below the pressure plate 18 through a bearing. The outer side of the rotating shaft 16 is fixed with a ring-shaped trapezoidal plate 26 and an L-shaped rod 27. A paddle plate No. 13 and a paddle plate No. 2 14 are provided on one side of the trapezoidal plate 26, and the rotating groove 19 is set as a spiral structure.

[0041] The device for testing the water resistance of interior wall decoration materials, when the hydraulic cylinder 7 pushes the pressure plate 18 downward, the pressure plate 18 drives the rotating shaft 16 to move downward, so that the rotating shaft 16 drives the guide rod 17 to move downward. Since the end of the guide rod 17 is in sliding connection with the rotating groove 19, the guide rod 17 will be squeezed by the rotating groove 19 when it moves downward, so that the end of the guide rod 17 slides along the trajectory of the rotating groove 19 of the sleeve 15. Since the rotating groove 19 is set to be spiral, the guide rod 17 will rotate when sliding, so that the guide rod 17 drives the rotating shaft 16 to rotate, and the rotating shaft 16 then drives the first paddle 13 and the second paddle 14 to rotate through the trapezoidal plate 26, which can stir the water body. Since the influence of static water on material samples is different from the influence under dynamic conditions, stirring the water body can increase the contact area between the water body and the surface of the material sample, improve the penetration speed of the water body, shorten the detection time, and cooperate with the downward movement of the pressure plate 18, without the need for additional power to drive the rotation, thereby improving the detection efficiency while reducing energy consumption.

[0042] See also Figure 5 and Figure 7-11 , one side of the trapezoidal plate 26 and the L-shaped rod 27 is connected to a rotating mechanism 6, and the rotating mechanism 6 includes a square frame 601 fixed to the bottom end of the L-shaped rod 27, and a strip groove is provided on the inner side of the square frame 601, and a slide rod 602 is fixed inside the strip groove, and a round rod 603 is slidably sleeved on the outer side of the slide rod 602, and a rack 604 is fixedly connected to one side of the round rod 603. The outer surface of the extrusion cylinder 21 is set as a slope structure, and the upper end diameter of the extrusion cylinder 21 is smaller than the lower end diameter. The bottom end of the sleeve 15 is fixedly connected to the support frame 20, and the extrusion cylinder 21 is connected to the top of the support frame 20.

[0043] This is a device for testing the water resistance of interior wall decoration materials. When the bottom end of the rotating shaft 16 approaches and enters the interior of the extrusion cylinder 21, the rotating shaft 16 will drive the L-shaped rod 27 to descend, and the L-shaped rod 27 will then drive the square frame 601 to descend, so that one end of the round rod 603 approaches the outer inclined surface of the extrusion cylinder 21. Due to the inclined surface setting of the extrusion cylinder 21, the round rod 603 is squeezed by the inclined surface and moves to one side. At the same time, the round rod 603 drives the rack 604 to slide toward the end away from the extrusion cylinder 21, and then engages with the gear 606.

[0044] See also Figures 8-10 The ends of the No. 1 paddle board 13 and the No. 2 paddle board 14 are fixedly connected with symmetrically distributed transmission shafts, and the ends of the transmission shafts away from the No. 1 paddle board 13 and the No. 2 paddle board 14 are respectively fixedly connected with a gear 606 and a half gear plate 605.

[0045] The device for detecting the water resistance of interior wall decoration materials, after the rack 604 is meshed with the gear 606, the rack 604 will drive the gear 606 to rotate clockwise, and since the gear 606 is meshed with the half-toothed disc 605, the gear 606 drives the half-toothed disc 605 to rotate counterclockwise, so that the gear 606 and the half-toothed disc 605 simultaneously drive the first paddle plate 13 and the second paddle plate 14 to rotate in opposite directions through the transmission shaft. More specifically, the number of tooth blocks on the rack 604, the gear 606 and the half-toothed disc 605 can be set according to actual conditions, so that when the first paddle plate 13 and the second paddle plate 14 rotate, the opening and closing angle generated is within 100°. 20°-30°, through the combination of the rotating shaft 16 and the rotating mechanism 6, the No. 1 paddle plate 13 and the No. 2 paddle plate 14 are driven to open once during the circular rotation, and the opening distance between the No. 1 paddle plate 13 and the No. 2 paddle plate 14 can be increased when the No. 1 paddle plate 13 and the No. 2 paddle plate 14 are close to the bottom end of the water injection cylinder 5, so that the No. 1 paddle plate 13 and the No. 2 paddle plate 14 produce a greater water flow dynamic effect in the process of stirring the water, simulate different detection environments, and increase the impact force of water on the surface of the material sample. In addition, the distance between the No. 1 paddle plate 13 and the No. 2 paddle plate 14 can provide water flow, reduce rotational resistance, optimize the test environment, and ensure the stability and reliability of the test results.

[0046] Please refer to the figure Figures 8-10 The rack 604 and the gear 606 are meshedly connected, the trapezoidal plate 26 is connected to the transmission shaft through a bearing, and a return spring 28 is sleeved on the outer side of the slide rod 602.

[0047] This device for detecting the water resistance of interior wall decoration materials is configured such that when the rotating shaft 16 drives the paddle plate No. 13 and the paddle plate No. 2 14 to rise and rotate, the round rod 603 slides on the inclined surface of the extrusion cylinder 21. Due to the rebound of the return spring 28, the round rod 603 can be driven to slide to its original position on the outside of the slide bar 602, so that the rotating mechanism 6 drives the paddle plate No. 13 and the paddle plate No. 2 14 to rotate and return to their original positions.

[0048] See also Figure 1-Figure 4 、 Figure 7 、 Figure 12 、 Figure 14 and Figure 15 The lower surface of the water injection cylinder 5 is fixedly connected to a cover plate 10, and a support bracket 4 is installed above the detection box 1 near the cover plate 10. A detection groove 9 is opened on the inner side of the detection box 1 near the support bracket 4, and a humidity sensor 29 is installed on the inner bottom surface of the detection groove 9. The interior of the support bracket 4 is provided with square placement grooves of different sizes.

[0049] This is a device for testing the water resistance of interior wall decoration materials. During testing, a material sample can be placed inside a support frame 4. Since placement slots of different sizes are provided inside the support frame 4, material samples of different sizes can be placed. Then, a cover plate 10 is put on the outside of the support frame 4. A sealing ring structure can be provided on the inner wall of the cover plate 10 to prevent water from flowing out. When water flows from the surface of the material sample to the bottom of the material sample, the humidity sensor 29 in the detection slot 9 can sense moisture, indicating that the material sample has been penetrated.

[0050] See also Figure 5 、 Figure 7 、 Figure 8 and Figure 11 A sleeve 31 is fixed on the inner wall of the detection groove 9, and a top frame 30 is movably connected to the inner side of the sleeve 31. A top frame 30 is movably connected to the inner side of the sleeve 31. A top material mechanism 8 is provided on one side of the top frame 30, and one end of the top material mechanism 8 is installed on the outside of the detection box 1.

[0051] This device for testing the water resistance of interior wall decoration materials is usually used to manually take out material samples after the test is completed. However, most material samples are flat plate structures, which are not very convenient to take out. The lifting mechanism 8 can drive the lifting frame 30 to lift the material sample at the diagonal position, and the lifting frame 30 slides on the inner side of the sleeve frame 31. The sleeve frame 31 guides the sliding of the lifting frame 30, and the lifting frame 30 pushes the material sample out of the built-in groove of the support frame 4, making it convenient for staff to take it out.

[0052] See also Figure 2 、 Figure 3 and Figure 12-16 The ejection mechanism 8 includes a push rod 803 and a push rod 804 that slide through one side of the detection box 1. The push rods 803 and 804 are fixedly connected to a ejection block 801 at one end close to the ejection frame 30. The outer sides of the push rods 803 and 804 are sleeved with support springs 802. A cross bar 805 is connected between the ends of the push rods 803 and 804. A fixed block 24 is welded on the outer wall of the detection box 1. The fixed block 24 A connecting frame 25 is slidably sleeved on the inner side of the top plate 3, and a positioning rod 23 is installed on the side of the top plate 3 close to the connecting frame 25. The positioning rod 23 and the end of the connecting frame 25 are slidably sleeved. A guide groove 806 for sliding the cross bar 805 is opened on the inner side of the connecting frame 25. A roller is provided at the bottom end of the top frame 30 through a movable shaft. The cross-sectional shape of the top block 801 is set to a right-angled trapezoid, and the guide groove 806 is set to an inclined structure. The material of the support spring 802 can be selected from carbon steel or alloy steel.

[0053] The device for testing the water resistance of interior wall decoration materials further specifically describes the operation process of the top material mechanism 8. When the electric lifting rod 2 drives the top plate 3 to rise, the positioning rod 23 on one side of the top plate 3 also moves upward. Since the positioning rod 23 is connected with the connecting frame 25, the positioning rod 23 lifts the connecting frame 25 upward, causing the connecting frame 25 to rise. At the same time, the connecting frame 25 drives the guide groove 806 to rise, so that the guide groove 806 squeezes the cross bar 805, and the cross bar 805 slides along the inclined surface of the guide groove 806, thereby shortening the distance between the cross bar 805 and the outer wall of the detection box 1, so that the cross bar 805 pushes the No. 1 push rod 803 and the No. 2 push rod 804 to move at the same time, and then the No. 1 push rod 803 and the No. 2 push rod 804 move simultaneously. 03 and No. 2 push rods 804 then push the top block 801 to move horizontally. Since the side of the top block 801 that contacts the top frame 30 is set to an inclined structure, the top block 801 squeezes the bottom end of the top frame 30, so that the top frame 30 rises along the inclined surface, which is convenient for pushing out the material sample. The elastic support of the support spring 802 can prevent the No. 1 push rod 803 and the No. 2 push rod 804 from moving horizontally too fast, thereby improving the stability of the top frame 30. The top plate 3 rises and drives the connecting frame 25 to rise, thereby making the top material mechanism 8 operate. At the same time, the top plate 3 drives the cover plate 10 to separate from the supporting frame 4, the top material mechanism 8 pushes the material sample out, thereby improving the convenience of the water resistance performance testing device for interior wall decoration materials.

[0054] In summary, when using the water resistance testing device for interior wall decoration materials, first place the material sample into the built-in groove of the support frame 4, the electric lifting rod 2 drives the top plate 3 to move downward, and the top plate 3 then drives the water injection cylinder 5 to drive the cover plate 10 to be sleeved on the outside of the support frame 4, and then the water inlet hose 12 inputs the water flow into the water injection cylinder 5. The water level is lower than the pressure plate 18, and the hydraulic cylinder 7 pushes the pressure plate 18 downward, so that the pressure plate 18 generates a certain pressure on the water in the water injection cylinder 5, thereby accelerating the infiltration speed, and at the same time drives the No. 1 paddle plate 13 through the rotating groove 19 and the rotating mechanism 6. The rotation of the No. 2 paddle 14 and the increase of the opening angle can disturb the water body while reducing the rotational resistance, increase the contact area between the water body and the surface of the material sample, increase the penetration rate of the water body, shorten the detection time, and improve the detection efficiency on the basis of reducing energy consumption. After the detection is completed, the top plate 3 rises to drive the material pushing mechanism 8 to operate, and push the material sample out for the convenience of the staff to take it, thereby improving the convenience of the water resistance performance detection device of the interior wall decoration material.
