Description

Technical Field

[0001] This utility model relates to the field of antifungal agent testing technology, specifically to an antifungal agent heat resistance testing device. Background Technology

[0002] Antifungal agents are additives used to prevent the growth of mold. Food, fruits, feed, cosmetics, paints, adhesives, leather, aquatic products, and plastics are susceptible to mold contamination during use and storage, leading to spoilage. To prevent mold growth, antifungal agents must be added to the products.

[0003] When testing antifungal agents, it is generally necessary to test their heat resistance to avoid affecting their effectiveness in high temperatures. Production can be avoided by ensuring that the antifungal agent's heat resistance is qualified before proceeding. The heat resistance test of antifungal agents usually involves spraying the antifungal agent onto the test sample and then testing the sample. Currently, the common method for testing samples is to directly place them in an insulated chamber and then heat them up for observation. This testing method is prone to uneven heating of the sample, which can lead to inaccurate test results.

[0004] Therefore, we propose a device for testing the heat resistance of antifungal agents. Utility Model Content

[0005] The purpose of this invention is to provide a device for testing the heat resistance of antifungal agents, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat resistance testing device for antifungal agents, comprising a test chamber, inside which are installed two fixing frames and a fixing component. The fixing component is installed inside the fixing frames and is used to fix the sample for testing, preventing the sample from falling during testing. A testing component is installed inside the test chamber and is used to heat the sample more evenly during the heat resistance testing of the antifungal agent.

[0007] Preferably, the fixing component includes two mounting brackets, the size of which is adapted to the size of the inner wall of the fixing bracket. Each of the two fixing brackets has a fixedly connected insert block on its bottom wall. Each insert block has a sliding groove on its opposite side. A limit block is engaged inside each sliding groove. A first spring is fixedly connected between each limit block and the inner wall of the sliding groove. A guide rod is fixedly connected between the top and bottom walls of the two mounting brackets. A placement plate is engaged between the top and bottom walls of the mounting bracket via the guide rod. A second spring, sleeved with the guide rod, is fixedly installed between the bottom surface of the placement plate and the bottom wall of the mounting bracket.

[0008] Preferably, the bottom surface of the mounting bracket engages with the insert block.

[0009] Preferably, push rods are snapped onto the front of the left-side fixing frame and the back of the right-side fixing frame, and a push handle is fixedly installed on the side of each push rod away from the fixing frame. A set of elastic steel plates is fixedly installed between each push handle and the fixing frame.

[0010] Preferably, the position of each push rod corresponds to the straight surface of its corresponding limiting block.

[0011] Preferably, the test assembly includes two fixing plates, both of which are installed on the lower part of the inner wall of the test chamber. A rotating shaft is rotatably connected between the adjacent sides of the two fixing plates. The two rotating shafts are rotatably connected to two corresponding fixing frames. A drive motor is fixedly embedded on the right side of the test chamber. The rotating shaft on the right side is fixedly connected to the output shaft of the drive motor. Several evenly distributed hot air blowers are fixedly installed on the inner wall of the test chamber.

[0012] Preferably, a base is fixedly mounted on the outer surface of the test chamber.

[0013] Preferably, the test chamber has a hinged door on the upper part of its outer surface.

[0014] This utility model has at least the following beneficial effects:

[0015] 1. When testing the heat resistance of a mildew inhibitor, first spray the mildew inhibitor onto the surface of the test sample, then place the sample on the surface of the placement plate. Next, insert the entire mounting bracket into the interior of the fixing frame. At this time, the insert block will insert into the bottom wall of the mounting bracket, and then the bottom surface of the mounting bracket will press against the inclined surface of the limiting block, causing the limiting block to retract into the sliding groove. When the mounting bracket is inserted into the appropriate position, the limiting block will automatically pop out under the elastic force of the first spring, achieving a locked position of the mounting bracket. At this time, the bottom surface of the placement plate will be pressed by the insert block, and under the guidance of the guide rod, the entire placement plate will rise. At this time, the sample on the surface of the placement plate will contact and press against the top wall of the mounting bracket, thus achieving the purpose of firmly fixing the test sample. When the sample needs to be removed after testing, the staff only needs to press the two push handles towards the mounting bracket. At this time, the push rod will push the limit block into the inside of the slide groove. Then, gently pull the entire mounting bracket upwards so that the limit block can be inserted into the bottom surface of the mounting bracket by a small part. After releasing the push force on the push handle, the push rod will automatically reset under the action of the elastic steel plate, thus achieving the purpose of removing the entire mounting bracket.

[0016] By setting up a fixing component, it is more convenient to fix the sample to be tested, and the sample can be made more stable during testing.

[0017] 2. After the sample is fixed on the surface of the placement plate, install the mounting bracket inside the fixed bracket. At this time, simply close the opening and closing door, then turn on the power switch of the hot air blower to generate heat. Then turn on the power switch connected to the drive motor. The output shaft of the drive motor will drive the rotating shaft on the right side to rotate. At this time, the fixed bracket on the right side will be connected to the fixed bracket on the left side through the placement plate, causing both fixed brackets to rotate slowly at the same time, further allowing the sample on the surface of the placement plate to rotate.

[0018] By setting up the test components, the sample on the surface of the plate can be rotated while being heated, which further makes the heating of the sample on the surface of the plate more uniform, and thus makes the test results more accurate. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-4 This utility model provides a technical solution:

[0027] Example 1: A heat resistance testing device for antifungal agents includes a test chamber 3, inside which are installed two fixing frames 7 and a fixing component 1. The fixing component 1 is installed inside the fixing frame 7 and is used to fix the sample to be tested, preventing the sample from falling during testing. The test component 2 is installed inside the test chamber 3 and is used to heat the sample more evenly during the heat resistance test of the antifungal agent.

[0028] The fixing component 1 includes a mounting bracket 8, of which there are two. The size of the two mounting brackets 8 is adapted to the size of the inner wall of the fixing bracket 7. The bottom wall of each fixing bracket 7 is fixedly connected with a plug 11. The side of each plug 11 that is far away from each other is provided with a sliding groove 21. A limit block 12 is engaged inside each sliding groove 21. A first spring 13 is fixedly connected between each limit block 12 and the inner wall of the sliding groove 21. A guide rod 17 is fixedly connected between the top wall and the bottom wall of each mounting bracket 8. A placement plate 9 is engaged between the top wall and the bottom wall of the mounting bracket 8 through the guide rod 17. A second spring 18 that is sleeved with the guide rod 17 is fixedly installed between the bottom surface of the placement plate 9 and the bottom wall of the mounting bracket 8.

[0029] The bottom surface of the mounting bracket 8 is engaged with the insert block 11.

[0030] Push rods 14 are snapped onto the front of the left fixed frame 7 and the back of the right fixed frame 7. Each push rod 14 has a push handle 15 fixedly installed on the side away from the fixed frame 7. A set of elastic steel plates 16 is fixedly installed between each push handle 15 and the fixed frame 7.

[0031] The position of each push rod 14 corresponds to the straight surface of its corresponding limit block 12, which ensures that the push rod 14 can push the limit block 12.

[0032] When testing the heat resistance of the anti-mold agent, the anti-mold agent is first sprayed onto the surface of the test sample. Then, the sample is placed on the surface of the placement plate 9. Next, the mounting bracket 8 is inserted into the interior of the fixing bracket 7. At this time, the insert block 11 will be inserted into the bottom wall of the mounting bracket 8. Then, the bottom surface of the mounting bracket 8 will press against the inclined surface of the limiting block 12, which can then retract the limiting block 12 into the interior of the sliding groove 21. When the mounting bracket 8 is inserted into the appropriate position, the limiting block 12 will automatically pop out under the elastic force of the first spring 13, achieving a locked position for the mounting bracket 8. At this time, the bottom surface of the placement plate 9 will be pressed by the insert block 11. Under the guidance of the guide rod 17, the placement plate 9 will rise as a whole. At this time, the sample on the surface of the placement plate 9 will contact and press against the top wall of the mounting bracket 8, thus achieving the purpose of firmly fixing the test sample. When the sample needs to be removed after the test is completed, the staff only needs to press the two push handles 15 towards the position of the mounting bracket 8. At this time, the push rod 14 will push the limit block 12 into the interior of the slide groove 21. Then, after gently pulling the entire mounting bracket 8 upward, the limit block 12 can be inserted into a small part of the bottom surface of the mounting bracket 8. After releasing the push force on the push handle 15, the push rod 14 will automatically reset under the action of the elastic steel plate 16, thus achieving the purpose of removing the entire mounting bracket 8.

[0033] By setting the fixing component 1, it is more convenient to fix the sample to be tested, and the sample can be made more stable during testing.

[0034] Example 2: Test component 2 includes two fixing plates 5, both of which are installed on the lower part of the inner wall of the test chamber 3. A rotating shaft 6 is rotatably connected between the sides of the two fixing plates 5 that are close to each other. The two rotating shafts 6 are rotatably connected to two corresponding fixing frames 7. A drive motor 10 is fixedly embedded on the right side of the test chamber 3. The rotating shaft 6 on the right side is fixedly connected to the output shaft of the drive motor 10. Several evenly distributed hot air blowers 19 are fixedly installed on the inner wall of the test chamber 3.

[0035] A base 4 is fixedly installed on the outer surface of the test chamber 3 to support the entire device.

[0036] A hinged door 20 is attached to the upper part of the outer surface of the test chamber 3.

[0037] After the sample is fixed on the surface of the placement plate 9, and the mounting bracket 8 is installed inside the fixing bracket 7, simply close the opening and closing door 20, then turn on the power switch of the hot air blower 19 to blow air and generate heat. At this time, turn on the power switch that is electrically connected to the drive motor 10. The output shaft of the drive motor 10 will drive the rotating shaft 6 on the right to rotate. At this time, the fixing bracket 7 on the right will be connected to the fixing bracket 7 on the left through the placement plate 9, causing the two fixing brackets 7 to rotate slowly at the same time, further allowing the sample on the surface of the placement plate 9 to rotate.

[0038] By setting up test component 2, the sample on the surface of placement plate 9 can be rotated while being heated, which further makes the heating of the sample on the surface of placement plate 9 more uniform, thereby making the test results more accurate.
