Description

Technical Field

[0001] This application relates to the field of testing equipment technology, and in particular to a testing device for the thermal insulation performance of imitation stone paint. Background Technology

[0002] Stone-like paint is a decorative coating used on the exterior walls of buildings. By simulating the texture, grain, and color of natural stone (such as marble and granite), it offers a rich selection of three-dimensional patterns and shapes to meet diverse design needs. Furthermore, stone-like paint is UV resistant, mildew-proof, and algae-proof, and can withstand high temperatures, high humidity, and extreme cold climates, with a lifespan far exceeding that of ordinary ceramic tiles.

[0003] When faux stone paint leaves the factory, it needs to undergo performance testing, including heat insulation performance testing. During the test, the faux stone paint is first applied to a coating test panel, and then the coating test panel is placed inside the testing device. The heat insulation effect of the faux stone paint is tested by heating the internal environment of the device.

[0004] The existing Chinese patent with authorization announcement number CN206146864U discloses a heat insulation performance testing device, including a test box. The bottom center of the test box is provided with a heating wire for heating. The internal fixed frame of the test box is provided with a first simulation box and a second simulation box. The first simulation box holds a first test plate, and the second simulation box holds a second test plate. In the specific test, by applying a layer of stone-like paint to be tested to the bottom surface of the first test plate and a layer of ordinary wall paint to the bottom surface of the second test plate, the surface temperature of the first test plate and the second test plate are measured respectively, so as to compare whether the heat insulation performance of the stone-like paint is better than that of the ordinary wall paint.

[0005] However, regarding the aforementioned technical solutions, after completing the heat insulation work on the first and second test boards, both the first and second test boards absorb heat and rise in temperature. During the process of removing the test boards from the test box, the operators are at risk of being burned and need to wait for a certain cooling time. Therefore, when it is necessary to continuously test the heat insulation performance of the imitation stone paint board, the overall work efficiency is low and needs to be improved. Utility Model Content

[0006] Based on this, this application provides a testing device for the thermal insulation performance of imitation stone paint, which can improve the overall work efficiency when it is necessary to continuously test the thermal insulation performance of imitation stone paint panels.

[0007] The imitation stone paint heat insulation performance testing device provided in this application adopts the following technical solution:

[0008] A test device for testing the thermal insulation performance of imitation stone paint includes a test chamber for conducting thermal insulation tests and a frame module for fixing the coating test plate. The test chamber is divided into two test chambers by a partition plate, and each test chamber is equipped with a heating module. The top of the test chamber is provided with an interface for the frame module to be matched and plugged in, and the partition plate is provided with a clearance opening for the frame module to pass through.

[0009] The frame module includes two rectangular frames that are fixed to each other. In the test state, the two rectangular frames are located in two test chambers respectively. The rectangular frames are made of heat insulation material, and each inner wall of the rectangular frames is provided with a recessed groove. The coating test plate is matched and installed in the recessed groove.

[0010] The rectangular frame includes a C-shaped frame and a side post set on the opening side of the C-shaped frame. One end of the side post is hinged to the C-shaped frame, and the other end of the side post is detachably connected to the C-shaped frame through a snap-fit ​​mechanism.

[0011] By adopting the above technical solution, when conducting the thermal insulation performance test of faux stone paint, two coating test panels, one coated with faux stone paint and the other with ordinary wall paint, are placed inside two rectangular frames respectively, so that the coating test panels are locked in the concave slots. The side stops are rotated so that the free ends of the side stops are locked and fixed to the C-shaped frame through the locking mechanism, thereby sealing the opening of the C-shaped frame. Then, the entire frame module is inserted into the insertion interface. After the frame module is fully inserted, the two coating test panels can be located in two test chambers respectively. The heating modules in the test chambers heat the two test chambers respectively, and the temperature in the space on the other side of the coating test panel is detected. By comparison, it can be determined whether the thermal insulation performance of faux stone paint is better than that of ordinary wall paint.

[0012] After the thermal insulation performance test is completed, the entire frame module can be pulled out directly from the interface. The frame module can then be placed separately and cooled down to reduce the risk of workers being accidentally burned. Afterward, workers can use the new frame module to fix new stone-like paint panels and ordinary wall paint panels to be tested, so as to quickly carry out the next thermal insulation performance test. This can improve the overall work efficiency when the thermal insulation performance test of stone-like paint panels needs to be carried out continuously.

[0013] Optionally, the free end of the side stop column extends outward and is provided with a mounting part. The snap-fit ​​mechanism includes a snap-fit ​​member movably embedded in the inner side of the mounting part and a return spring provided between the snap-fit ​​member and the mounting part. The return spring is used to force the snap-fit ​​member to be partially exposed in the mounting part.

[0014] The C-shaped frame has a clearance area on one side for the installation part to enter, and a snap-fit ​​hole on the other side of the C-shaped frame that is connected to the clearance area. When the free end of the side stop post abuts against the C-shaped frame, the snap-fit ​​part is partially snapped into the snap-fit ​​hole to achieve the rotational positioning of the side stop post.

[0015] By adopting the above technical solution, after the coating test plate is inserted into the concave groove, the side stop is rotated so that the free end of the side stop abuts against the C-shaped frame. The snap-fit ​​component can abut against the C-shaped frame and move inward under force. At this time, the return spring is in a compressed state. After the free end of the side stop is fully attached to the C-shaped frame, the snap-fit ​​component is exactly in the position directly opposite the snap-fit ​​hole. At this time, the snap-fit ​​component can automatically enter the snap-fit ​​hole under the elastic force of the return spring, thereby realizing the detachable connection between the side stop and the C-shaped frame.

[0016] Optionally, the snap-fit ​​hole is set as an oblong hole, and a toggle block is slidably installed inside the snap-fit ​​hole. The toggle block is partially provided with a slanted guide surface. When the toggle block moves toward the snap-fit ​​component, the slanted guide surface abuts against the snap-fit ​​component and forces the snap-fit ​​component to disengage from the snap-fit ​​hole.

[0017] By adopting the above technical solution, when the snap-fit ​​component is inserted into the snap-fit ​​hole, the actuating block can be pushed by the snap-fit ​​component to stop on the outside of the snap-fit ​​component along the extension direction of the snap-fit ​​hole and to normally abut against the snap-fit ​​component; when the coating test plate needs to be removed after the frame module has cooled down, the actuating block is forced to move towards the snap-fit ​​component by applying force, and the inclined guide surface of the actuating block can abut against the snap-fit ​​component and force the snap-fit ​​component to smoothly disengage from the snap-fit ​​hole, which can facilitate the removal of the coating test plate and the subsequent insertion of a new coating test plate to be tested. The operation is convenient and labor-saving.

[0018] Optionally, the surface of the toggle block is provided with anti-slip texture.

[0019] By adopting the above technical solution, the anti-slip texture can increase the friction between the operator's hand and the actuating block, thereby making it easier for the operator to force the actuating block to move to release the connection lock between the side stop and the C-shaped frame.

[0020] Optionally, each test chamber is equipped with a temperature detector, and the temperature detector and the heating module are respectively set on two opposite inner side walls of the test chamber; the outer wall of the test chamber is equipped with a display for displaying the temperature detected by each temperature detector.

[0021] By adopting the above technical solution, the temperature detector can measure the temperature of the coating test panel on the side away from the heating module, and the measured temperature can be displayed on the screen, so that the operator can check the temperature and judge whether the heat insulation performance of the stone-like paint panel is good.

[0022] Optionally, a handle is fixed to the top of the upper rectangular frame of the two rectangular frames of the same frame module. When the frame module is matched and inserted into the interface, the handle is exposed on the top of the test box.

[0023] By adopting the above technical solution, the handle design makes it easier for operators to pick up the frame module, and the frame module can be easily inserted into or removed from the insertion interface, improving the convenience of loading and unloading operations.

[0024] Optionally, the test chamber is equipped with multiple vertically arranged partitions, which divide the interior of the test chamber into multiple test stations. Each test station is equipped with a partition plate and a frame module.

[0025] By adopting the above technical solution, the test chamber is divided into multiple test stations by partition walls. When conducting batch testing of the thermal insulation performance of imitation stone paint panels, multiple test stations can carry out testing operations together, which helps to further improve the overall work efficiency.

[0026] Optionally, each inner wall of each test station is bonded with heat insulation panels.

[0027] By adopting the above technical solution, the installation of heat insulation panels can reduce heat exchange between adjacent test stations, thereby reducing the temperature influence between adjacent test stations and helping to ensure the accuracy of test results.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By fixing two coating test panels to the inside of two rectangular frames respectively, and then inserting the entire frame module into the insertion interface, the two coating test panels can be located in two test chambers respectively. By heating the two test chambers respectively through the heating module and detecting the temperature in the space on the other side of the coating test panel, it can be determined whether the heat insulation performance of the stone-like paint is better than that of ordinary wall paint.

[0030] 2. After the thermal insulation performance test is completed, the entire frame module can be pulled out directly from the interface and placed separately for cooling. The operators can use the new frame module to fix the new stone-like paint board and ordinary wall paint board to be tested, so as to quickly carry out the next thermal insulation performance test. This can improve the overall work efficiency when the thermal insulation performance test of stone-like paint boards needs to be carried out continuously.

[0031] 3. By setting a toggle block, the operator can apply force to the toggle block to move the box closer to the snap-fit ​​part, which can make the snap-fit ​​part disengage smoothly from the snap-fit ​​hole, thus facilitating the removal of the coating test plate and the subsequent loading of a new coating test plate to be tested. The operation is convenient and labor-saving. Attached Figure Description

[0040] The following is in conjunction with the appendix Figure 1-7 This application will be described in further detail.

[0041] This application discloses a device for testing the thermal insulation performance of imitation stone paint.

[0042] Reference Figure 1 A device for testing the thermal insulation performance of imitation stone paint includes a test chamber 1 for conducting thermal insulation tests and a frame module 2 for fixing a coating test plate 6. Multiple sets of frame modules 2 can be provided for backup. (Refer to...) Figure 2 The test chamber 1 is a rectangular box with multiple vertically arranged baffles 19 inside. These baffles 19 divide the interior of the test chamber 1 into multiple test stations 17, all of which are equidistantly arranged along the extension direction of the test chamber 1. It should be noted that each inner wall of each test station 17 is bonded with a heat insulation board 18. In this embodiment, the heat insulation board 18 can be made of materials with good heat insulation properties, such as ceramic fiber board or rock wool board, to reduce the temperature influence between adjacent test stations 17 and ensure the accuracy of the test results.

[0043] Reference Figure 2Each test station 17 has a horizontally arranged partition plate 12 fixed inside, which divides the test station 17 into two test chambers 13. It should be noted that the material of the partition plate 12 can also be a ceramic fiber board or rock wool board, which have good heat insulation properties. Each partition plate 12 has a vertically penetrating clearance opening 121. The top of the test box 1 has multiple insertion interfaces 11, the number of which is equal to the number of test stations 17. Each insertion interface 11 is connected to a corresponding test station 17, and each insertion interface 11 is directly opposite to a clearance opening 121. The insertion interfaces 11 are designed to allow the frame module 2 to be inserted, and the frame module 2 can pass through the clearance opening 121 after being inserted into the insertion interface 11.

[0044] Back Figure 1 The frame module 2 includes two mutually fixed rectangular frames 3. The rectangular frames 3 are made of heat-insulating material, specifically stainless steel alloy or titanium alloy, which are materials with low thermal conductivity. The two rectangular frames 3 are used to fix the coating test panel 6 coated with imitation stone paint and the coating test panel 6 coated with ordinary wall paint, respectively. (See also...) Figure 2 In the test state, that is, after the coating test plate 6 is fixed in the frame module 2, and is matched and inserted into the insertion interface 11 and passes through the clearance opening 121, the two rectangular frames 3 can be located in the two test chambers 13 respectively, and the coating test plate 6 can vertically separate the test chambers 13 in which it is located.

[0045] Reference Figure 2 , Figure 3 Each test chamber 13 is equipped with a heating module 14 and a temperature detector 15, which are located on two opposite inner walls of the test chamber 13. The specific structure of the heating module 14 is a conventional design in the art, which can raise the temperature inside the test chamber 13 during operation, and will not be described in detail here. Furthermore, returning to... Figure 1 The outer wall of the test chamber 1 is equipped with a display 16, which is electrically connected to each temperature detector 15. It can receive and display the temperature signals detected by each temperature detector 15, so that the operators can compare the temperatures to determine whether the heat insulation performance of the stone-like paint is good.

[0046] Reference Figure 4 The rectangular frame 3 includes a C-shaped frame 31 and a side column 32. One end of the side column 32 is hinged to the C-shaped frame 31 via a hinge 321, and the other end of the side column 32 is free. The free end of the side column 32 is provided with a snap-fit ​​mechanism 4, which allows the side column 32 to be detachably connected to the C-shaped frame 31. The three inner walls of the C-shaped frame 31 and the inner side of the side column 32 are all provided with inner grooves. When the free end of the side column 32 is fixed to the C-shaped frame 31, the inner grooves can together form an inner groove 33 for fixing the coating test plate 6.

[0047] Specifically, refer to Figure 5 , Figure 6 The free end of the side stop post 32 is fixed with a mounting part 322. The mounting part 322 has a mounting groove 323 on its inner side, and a positioning hole 324 communicating with the mounting groove 323 is provided on the side of the mounting part 322. The snap-fit ​​mechanism 4 includes a snap-fit ​​member 41 and a return spring 42. The snap-fit ​​member 41 is movably embedded in the mounting groove 323, and the snap-fit ​​member 41 is partially provided with a locking part 411, which passes through the positioning hole 324. The return spring 42 is disposed between the snap-fit ​​member 41 and the inner wall of the mounting groove 323. The return spring 42 can always generate an elastic force acting on the snap-fit ​​member 41, thereby forcing the locking part 411 to pass through the positioning hole 324 and be partially exposed in the mounting part 322.

[0048] One side of the C-shaped frame 31 is provided with a clearance area 311 for the installation part 322 to enter, and the other side of the C-shaped frame 31 is provided with a snap-fit ​​hole 312, which is connected to the clearance area 311. In this embodiment, the snap-fit ​​hole 312 is set as an oblong hole, and the extension direction of the snap-fit ​​hole 312 is vertical. When the free end of the side stop post 32 abuts against the C-shaped frame 31, the locking part 411 can be set directly opposite the snap-fit ​​hole 312. At this time, under the elastic force of the return spring 42, the locking part 411 can automatically enter the snap-fit ​​hole 312, thereby making the locking part 411 smoothly snap into the bottom end of the snap-fit ​​hole 312, so as to realize the rotational positioning of the side stop post 32.

[0049] Back Figure 5 A sliding actuating block 5 is installed inside the snap-fit ​​hole 312. The surface of the actuating block 5 is provided with anti-slip texture 51, which facilitates the movement of the actuating block 5 by the operator; at the same time, refer to Figure 7 The actuating block 5 is partially provided with an inclined guide surface 52. In the locked state, the locking part 411 of the latching member 41 can abut against the inclined guide surface 52 of the actuating block 5. When no external force is applied, the actuating block 5 can just abut against the locking part 411. When it is necessary to remove the rectangular frame 3, the actuating block 5 is moved closer to the latching member 41 by applying force. At this time, the inclined guide surface 52 of the actuating block 5 can abut against the latching member 41 and force the latching member 41 to smoothly disengage from the latching hole 312, thereby quickly releasing the connection lock between the side stop 32 and the C-shaped frame 31.

[0050] Additionally, returning Figure 4 In the same frame module 2, the top of the upper rectangular frame 3 is fixed with a handle 34. In this embodiment, the handle 34 can be made of solid wood or ceramic material and also has low thermal conductivity. The operator can easily install the frame module 2 into the plug-in interface 11 and easily remove the frame module 2 from the plug-in interface 11 through the handle 34, which helps to improve the convenience of loading and unloading operations.

[0051] The implementation principle of the imitation stone paint heat insulation performance testing device in this application embodiment is as follows:

[0052] When conducting the thermal insulation performance test of the faux stone paint, two coating test plates 6, one coated with faux stone paint and the other with ordinary wall paint, are placed inside the two rectangular frames 3 respectively, so that the coating test plates 6 are locked in the recessed slots 33. The side stop post 32 is rotated so that the free end of the side stop post 32 is locked and fixed to the C-shaped frame 31 through the locking mechanism 4, thereby sealing the opening of the C-shaped frame 31. Then, the entire frame module 2 is inserted into the insertion interface 11. After the frame module 2 is fully inserted, the two coating test plates 6 are located in the two test chambers 13 respectively. The two test chambers 13 are heated by the heating module 14. The operator observes the temperature displayed on the monitor 16 located on the outside and can compare whether the thermal insulation performance of the faux stone paint is better than that of ordinary wall paint.

[0053] After the thermal insulation performance test is completed, the entire frame module 2 can be pulled out directly from the plug interface 11. The frame module 2 can be placed separately and cooled down to reduce the risk of workers being accidentally burned. Then, the workers can use the new frame module 2 to fix the new stone-like paint panels and ordinary wall paint panels to be tested, so as to quickly carry out the next thermal insulation performance test. This can improve the overall work efficiency when the thermal insulation performance test of stone-like paint panels needs to be carried out continuously.

[0054] The above are preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made to the structure, shape and principle of this application should be covered within the scope of protection of this application.
