[0038] Example 1

[0039] A device for testing the low temperature stability of elastic architectural coatings, such as Figure 1 and Figure 2 As shown, it includes a freezer 1, a fixing rod 11, a base 12, a glass door 2, a curing coating 21, a leakage detection mechanism 3 and an elastic strength measurement mechanism 4. The fixing rod 11 is welded to the upper left part of the base 12, and the freezer 1 is rotatably connected to the fixing rod 11. The glass doors 2 are symmetrically installed on the upper and lower sides of the front of the freezer 1 through bearings. The glass door 2 and the freezer 1 are magnetically engaged. The base 12 is provided with a leakage detection mechanism 3, the curing coating 21 is placed on the leakage detection mechanism 3, and the inside of the freezer 1 is provided with an elastic strength measurement mechanism 4.

[0040] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown, the leakage detection mechanism 3 includes a motor 31, a rotating shaft 32, a fixed block 33, a rubber plate 34, a first spring 35 and a fixed plate 36. The motor 31 is installed on the upper right part of the base 12. The rotating shaft 32 is installed on the left side of the output shaft of the motor 31 through a coupling. The rotating shaft 32 is fixedly connected to the freezer 1 and penetrates into the middle of the freezer 1. The number of the fixed blocks 33 is four. The four fixed blocks 33 are respectively welded to the upper and lower parts of the left side of the inner wall of the freezer 1 and the upper and lower parts of the right side of the inner wall. The upper and lower parts of the fixed blocks 33 are respectively welded to the upper and lower parts of the inner wall of the freezer 1. The front and rear sides of the freezer 1 are symmetrically fixed with fixed plates 36, and adjacent fixed plates 36 are slidably connected with rubber plates 34. There are two pieces of curing paint 21, one piece of curing paint 21 is placed between the upper rubber plates 34, and the other piece of curing paint 21 is placed between the lower rubber plates 34. The curing paint 21 is close to the inner rear wall of the freezer 1 and the rear side of the glass door 2. The front and rear parts of the rubber plates 34 are both wound with first springs 35, and the inner and outer ends of the first spring 35 are respectively fixed to the rubber plate 34 and the fixed plate 36.

[0041] like Figure 2 、 Figure 5 and Figure 6 As shown, the elastic strength measuring mechanism 4 includes a gear 41, a rack 42, an arc-shaped pressing block 43 and a slide rail 44. The gear 41 is welded to the rotating shaft 32, and the front lower part and the rear upper part of the fixed rod 11 are fixedly connected to the slide rail 44. There are two racks 42, and the two racks 42 are respectively slidably connected to the right sides of the two slide rails 44. The gear 41 is located in the middle of the rack 42, and the racks 42 are engaged with the gear 41. There are two arc-shaped pressing blocks 43, one arc-shaped pressing block 43 is connected to the lower part of the front rack 42, and the other arc-shaped pressing block 43 is fixed to the upper part of the rear rack 42. The upper and lower arc-shaped pressing blocks 43 are respectively in contact with the upper and lower curing coatings 21.

[0042] When it is necessary to test the stability of elastic architectural coatings under low temperature conditions, the present elastic architectural coatings low temperature stability testing device can be used. First, people rotate and open the two glass doors 2, then insert a piece of curing coating 21 between the lower rubber plates 34, and close the lower glass door 2. Then, add a proper amount of water into the freezer 1 through the upper open glass door 2. The water immediately falls on the lower curing coating 21. The gravity of the water deforms the lower curing coating 21. Then, another piece of curing coating 21 is inserted between the upper rubber plates 34, and the upper glass door 2 is closed. When the curing coating 21 is inserted between the rubber plates 34, the curing coating 21 squeezes the rubber plates 34 to move outward and open, the first spring 35 is compressed, and the first spring 35 is compressed. The elastic force of 35 enables the rubber plate 34 to fix the cured coating 21, which is beneficial to maintaining the stability of the cured coating 21 during the test, thereby improving the accuracy of the test results. Subsequently, the freezer 1 is powered on, and the freezer 1 cools the water to a low temperature state without freezing, thereby providing a low temperature environment for the test of the cured coating 21, thereby improving the accuracy of the test. Then, the motor 31 is started, and the output shaft of the motor 31 is controlled to rotate forward and backward by 180 degrees. The output shaft of the motor 31 drives the rotating shaft 32 to rotate forward and backward by 180 degrees. The rotating shaft 32 causes the freezer 1 to rotate forward and backward by 180 degrees, and the other parts on the freezer 1 rotate forward and backward by 180 degrees together, so that the positions of the upper and lower cured coatings 21 are reversed and restored. In the process of the solidified coating 21 rotating, when the solidified coating 21 rotates to below the water, the solidified coating 21 is deformed under the gravity of the water. When the solidified coating 21 rotates to above the water, the solidified coating 21 is no longer affected by the gravity of the water. If the shape of the solidified coating 21 can be restored, it indicates that the elasticity of the solidified coating 21 is qualified and the stability of the shape of the solidified coating 21 is qualified. If the shape of the solidified coating 21 cannot be restored, it indicates that the elasticity and stability of the solidified coating 21 are unqualified. In this way, the elasticity and stability of the solidified coating 21 can be tested, and two pieces of solidified coating 21 can be tested at a time. The test efficiency of the solidified coating 21 is relatively high. Moreover, when water falls on the solidified coating 21, people can see through the glass door 2 Observe whether there is water seepage on the cured coating 21. If so, it indicates that the waterproof performance of the cured coating 21 does not meet the standard. If not, it indicates that the waterproof performance of the cured coating 21 meets the standard. In this way, the waterproof performance of the cured coating 21 can be tested, so there is no need to use other equipment to test the waterproof performance of the cured coating 21. The functionality and practicality are strong. The positive rotation of the rotating shaft 32 drives the positive rotation of the gear 41. The positive rotation of the gear 41 causes the rack 42 to move outward, thereby causing the arc-shaped pressing block 43 to move outward and impact the cured coating 21, thereby causing the cured coating 21 to deform. The reverse rotation of the rotating shaft 32 causes the gear 41 to reverse. The reverse rotation of the gear 41 causes the rack 42 to move inward, thereby causing the arc-shaped pressing block 43 to move inward and separate from the cured coating 21.The degree of recovery of the cured coating 21 and the time required for recovery can be observed through the glass door 2. This allows the elastic strength of the cured coating 21 to be tested, which helps improve the test data and the accuracy of the test results. When the test of the cured coating 21 is completed, the power to the freezer 1 is turned off, the motor 31 is turned off, and the glass door 2 is opened. The water in the freezer 1 is drained, and the cured coating 21 is removed. The first spring 35 is reset, causing the rubber plate 34 to move inward and return to its original position.

[0043] Example 2

[0044] On the basis of Example 1, Figure 2 、 Figure 7 and Figure 8 As shown, it also includes a whole-surface testing mechanism 5, which includes a sliding frame 51, a buffer block 52, a second spring 53, a soft plate 54 and an iron ball 55. There are two sliding frames 51, and the two sliding frames 51 are respectively connected to the upper and lower parts of the freezer 1 in a sliding manner. The buffer block 52 is fixed in the middle of the side where the sliding frames 51 are close to each other. There are two second springs 53, and the two second springs 53 are respectively wound around the two sliding frames 51. The inner and outer ends of the second spring 53 are respectively connected to the sliding frame 51 and the freezer 1. Eight soft plates 54 are uniformly welded circumferentially on the side where the sliding frames 51 are close to each other. A plurality of iron balls 55 are welded on the side of the soft plate 54 close to the rotating shaft 32. The iron balls 55 on the upper and lower parts are respectively in contact with the cured coatings 21 on the upper and lower parts.

[0045] When the arc-shaped pressing block 43 moves outward to impact the curing coating 21, the curing coating 21 impacts the buffer block 52, thereby causing the sliding frame 51, the soft board 54, and the iron ball 55 to shake, the second spring 53 deforms adaptively, and the soft board 54 deforms to swing the iron ball 55, and the iron ball 55 is stained with water droplets and impacts the curing coating 21. This can simulate the impact of rain on the building wall, which is closer to the actual situation and is conducive to improving the test accuracy. The iron ball 55 can be used to impact multiple parts of the curing coating 21, which is conducive to testing multiple parts of the curing coating 21 and improving the measurement accuracy. In addition, the buffer block 52 can be used to protect the curing coating 21 to prevent the curing coating 21 from being damaged by hard collision with the sliding frame 51, which is conducive to improving the safety of the curing coating 21 test.

[0046] like Figure 2 、 Figure 9 and Figure 10As shown, a reinforcement mechanism 6 is also included, which includes a telescopic plate 61, a connecting frame 62, a connecting rod 63 and an extrusion frame 64. The connecting frame 62 is welded to the fixed plate 36, and the telescopic plate 61 is mounted on the connecting frame 62 through a bearing. The telescopic plate 61 is rotatably connected to the adjacent rubber plate 34, and the connecting rod 63 is mounted on the telescopic plate 61 through a bearing, and the extrusion frame 64 is fixed to the connecting rod 63.

[0047] When the curing coating 21 is inserted between the rubber plates 34, the rubber plates 34 move outward, and the outward movement of the rubber plates 34 causes the telescopic plates 61 to rotate inward and adaptively expand and contract. The inward rotation of the telescopic plates 61 causes the squeezing frame 64 to move inward through the connecting rod 63. The squeezing frame 64 moves inward and presses on the curing coating 21. This can reinforce the curing coating 21 and prevent the curing coating 21 from shaking during the test, which is conducive to improving the accuracy of the test results. When the curing coating 21 needs to be removed, the squeezing frame 64 can be manually pulled outward.

[0048] like Figure 2 、 Figure 11 and Figure 12 As shown, the vibration mechanism 7 is further included. The vibration mechanism 7 includes a rubber ball 71, a third spring 72 and a sliding rod 73. There are two sliding rods 73, which are respectively slidably connected to the left and right sides of the rotating shaft 32. The third spring 72 is fixedly connected to the side of the sliding rod 73 that is away from each other. The rubber ball 71 is fixedly connected to the side of the third spring 72 that is away from each other. The upper and lower rubber balls 71 are in contact with the upper and lower curing coatings 21 respectively.

[0049] The rotation of the rotating shaft 32 drives the sliding rod 73, the third spring 72 and the rubber ball 71 to rotate together. The rotation of the rotating shaft 32 generates centrifugal force, which causes the rubber ball 71 to move outward to impact the cured coating 21. The third spring 72 is stretched, thereby increasing the deformation of the cured coating 21, which is conducive to testing the elastic strength of the cured coating 21. When the rotating shaft 32 stops rotating, the sliding rod 73, the third spring 72 and the rubber ball 71 stop rotating. The third spring 72 returns to its original position, causing the rubber ball 71 to move inward and return to its original position.

[0050] like Figure 1 、 Figure 2 and Figure 13 As shown, it also includes a leak-proof mechanism 8, which includes a leak-proof block 81, a fourth spring 82 and a fixing frame 83. The fixing frame 83 is welded to the right front part of the freezer 1, and the upper and lower parts of the fixing frame 83 are symmetrically slidably connected to the leak-proof block 81. The fourth spring 82 is wound around the leak-proof block 81, and the inner and outer ends of the fourth spring 82 are respectively fixed to the leak-proof block 81 and the fixing frame 83. The upper and lower leak-proof blocks 81 are respectively pressed on the upper and lower glass doors 2.

[0051] During the rotation of the freezer 1, the elastic force of the fourth spring 82 causes the leak-proof block 81 to press the glass door 2, which can enhance the stability of the glass door 2 and prevent water leakage when the glass door 2 is opened, which is conducive to the stable and smooth test of the cured coating 21. When the glass door 2 needs to be opened or closed, the leak-proof block 81 is pulled forward and the fourth spring 82 is compressed. Then the glass door 2 can be opened or closed, and then the leak-proof block 81 is released. The fourth spring 82 is reset, causing the leak-proof block 81 to move inward and reset.
