Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a device with high sealing performance for testing the compatibility of multilayer sealants. Background Technology

[0002] A sealant compatibility testing device is a testing instrument used for compatibility testing of silicone structural sealants for building construction and accessories for structural assembly systems. This device is primarily used to predict the durability of materials exposed to outdoor environments. Its working principle mainly involves simulating damage caused by exposure to ultraviolet fluorescent lamps. However, existing testing devices typically only include a single oven. During testing, multiple batches of sealant usually need to be tested. Testing only one type of sealant at a time significantly reduces testing efficiency and fails to meet requirements. Using multiple testing devices greatly increases testing costs. Therefore, a multi-layered sealant compatibility testing device is needed. However, during experiments, the more doors in the oven, the worse the overall sealing and insulation performance of the testing device, affecting testing efficiency and accuracy. Summary of the Invention

[0003] To address the aforementioned issues, this invention provides a high-sealing-performance device for testing the compatibility of multilayer sealants, which improves sealing performance, detection efficiency, and detection accuracy.

[0004] The technical solution of this utility model is as follows: A compatibility testing device for multilayer sealants with high sealing performance includes an oven, a sealing device connected to the oven, and a controller. The oven is provided with several partition plates and several ultraviolet fluorescent lamps connected inside the oven. The partition plates divide the oven into several testing spaces, each with its own ultraviolet fluorescent lamp. The sealing device includes several sealing baffles hinged to the oven, a door handle movably connected to the sealing baffles, a limiting block fixedly connected to the oven, and several sealing strips fixedly connected to the sealing baffles. The oven is provided with several sealing grooves, the shape and size of which are adapted to the sealing strips on each sealing baffle. The number of sealing grooves is the same as the number of sealing baffles. The limiting block is provided with a limiting groove, the shape and size of which are adapted to the door handle. When the door handle is rotated at a certain angle and connected to the limiting groove, the sealing baffle and the oven form a closed space. The controller is electrically connected to the ultraviolet fluorescent lamps.

[0005] Using the above technical solution, firstly, the sealant to be tested is applied to the glass and placed inside the testing space of the oven. Then, the sealing baffle is rotated to seal the testing space. Next, the door handle is rotated so that one end of the door handle is engaged in the limiting groove. At this time, the sealing strip on the sealing baffle will be engaged in the sealing groove, which can greatly improve the sealing performance of the testing space. Then, the ultraviolet fluorescent lamp is turned on by the controller to conduct the sealant compatibility test. Since the partition plate divides the oven into several testing spaces, multiple tests can be carried out simultaneously, greatly improving the testing efficiency.

[0006] A further feature of this invention is that the door handle is provided with a rubber pad, and the door handle can be interference-fitted with the limiting groove.

[0007] By adopting the above technical solution, since the door handle is equipped with a rubber pad, which has a certain degree of flexibility, the door handle can be interference-fitted with the limiting groove. This can further improve the tightness of the connection between the sealing baffle and the oven, thereby improving the sealing of the detection space and thus improving the accuracy of the detection.

[0008] A further feature of this invention is that the partition plate is provided with a heat insulation layer, and each partition plate is provided with two heat insulation layers, which are respectively provided at the top and bottom of the partition plate. The cross-sectional shape and size of the heat insulation layer are adapted to the cross-sectional shape and size of the partition plate.

[0009] By adopting the above technical solution, since each partition board is equipped with two insulation layers, which are respectively set at the top and bottom of the partition board, the insulation layers can play a heat insulation role, which can ensure that heat energy can be transferred between two adjacent detection spaces, thereby reducing heat loss, improving detection efficiency, and reducing energy consumption.

[0010] A further feature of this invention is that the oven is provided with several connecting slots, connecting pipes connected to the connecting slots, and a negative pressure pump connected to the connecting pipes. The connecting slots are connected to the sealing slots, and the number of connecting slots and connecting pipes is the same as the number of sealing slots. The controller is electrically connected to the negative pressure pump.

[0011] Using the above technical solution, after the sealing baffle is placed on the oven, the negative pressure pump is started by the controller. The negative pressure pump provides negative pressure to the connecting pipe, so that the pressure inside the sealing groove is less than that outside, thereby further improving the tightness of the connection between the sealing groove and the sealing strip, thereby improving the sealing performance of the detection space, and improving the detection accuracy and efficiency.

Detailed Implementation

[0015] like Figure 1-2 As shown, a high-sealing-performance compatibility testing device for multilayer sealants includes an oven 1, a sealing device 2 connected to the oven 1, and a controller 3. The oven 1 is equipped with several partition plates 4 and several ultraviolet fluorescent lamps 5 connected inside the oven 1. The partition plates 4 divide the oven 1 into several testing spaces 6, each testing space 6 containing an individual ultraviolet fluorescent lamp 5. The sealing device 2 includes several sealing baffles 7 hinged to the oven 1, a door handle 8 movably connected to the sealing baffles 7, a limiting block 9 fixedly connected to the oven 1, and a fixed... A plurality of sealing strips 10 are connected to the sealing baffle 7. The oven 1 is provided with a plurality of sealing grooves 11. The shape and size of the sealing grooves 11 are adapted to the sealing strips 10 on each sealing baffle 7. The number of sealing grooves 11 is the same as the number of sealing baffles 7. The limiting block 9 is provided with a limiting groove 12. The limiting groove 12 is adapted to the shape and size of the door handle 8. When the door handle 8 is rotated at a certain angle and the door handle 8 is connected to the limiting groove 12, the sealing baffle 7 and the oven 1 form a closed space. The controller 3 is electrically connected to the ultraviolet fluorescent lamp 5.

[0016] First, the sealant to be tested is applied to the glass and placed inside the testing space 6 of the oven 1. Then, the sealing baffle 7 is rotated to seal the testing space 6. Next, the door handle 8 is rotated so that one end of the door handle 8 is engaged in the limiting groove 12. At this time, the sealing strip 10 on the sealing baffle 7 will be engaged in the sealing groove 11, which can greatly improve the sealing performance of the testing space 6. Then, the ultraviolet fluorescent lamp 5 is turned on by the controller 3 to conduct the sealant compatibility test. Since the partition plate 4 divides the oven 1 into several testing spaces 6, multiple tests can be carried out simultaneously, greatly improving the test efficiency.

[0017] The door handle 8 is provided with a rubber pad 13, and the door handle 8 can be interference-fitted with the limiting groove 12.

[0018] Because the door handle 8 is equipped with a rubber pad 13, which has a certain degree of flexibility, the door handle 8 can be interference-fitted with the limiting groove 12. This can further improve the tightness of the connection between the sealing baffle 7 and the oven 1, thereby improving the sealing of the detection space 6 and thus improving the accuracy of the detection.

[0019] The partition plate 4 is provided with a heat insulation layer 14. Each partition plate 4 is provided with two heat insulation layers 14. The two heat insulation layers 14 are respectively provided at the top and bottom of the partition plate 4. The cross-sectional shape and size of the heat insulation layer 14 are adapted to the cross-sectional shape and size of the partition plate 4.

[0020] Since each partition plate 4 is provided with two insulation layers 14, which are respectively set at the top and bottom of the partition plate 4, the insulation layers 14 can play a heat insulation role, which can ensure that the heat energy in the two adjacent detection spaces 6 can be transferred, thereby reducing heat loss, improving detection efficiency, and reducing energy consumption.

[0021] The oven 1 is provided with a plurality of connecting slots 15, connecting pipes 16 connected to the connecting slots 15 and negative pressure pumps 17 connected to the connecting pipes 16. The connecting slots 15 are connected to the sealing slots 11. The number of connecting slots 15 and connecting pipes 16 is the same as the number of sealing slots 11. The controller 3 is electrically connected to the negative pressure pump 17.

[0022] After the sealing baffle 7 is placed on the oven 1, the negative pressure pump 17 is started to work by the controller 3. The negative pressure pump 17 provides negative pressure to the connecting pipe 16, so that the pressure inside the sealing groove 11 is less than that outside, thereby further improving the tightness of the connection between the sealing groove 11 and the sealing strip 10, thereby improving the sealing performance of the detection space 6, and improving the detection accuracy and efficiency.
