Description

Technical Field

[0001] This utility model belongs to the technical field of carbon dioxide environmental simulation test chambers, and specifically relates to a carbon dioxide environmental simulation test device. Background Technology

[0002] In many fields such as materials science, civil engineering, and environmental engineering, cement is a basic and widely used building material. The stability of its performance under different environmental conditions is crucial. In order to gain a deeper understanding of the performance of cement in various actual environments and provide a reliable basis for engineering applications, carbon dioxide environmental simulation test equipment has emerged. This equipment can simulate complex and diverse environmental conditions, such as high and low temperatures, different humidity levels, and positive and negative pressures. It introduces carbon dioxide in a specific state into the test chamber to conduct environmental simulation tests on cement samples, thereby accurately evaluating the performance changes of cement under the combined effects of different environmental factors. Traditional carbon dioxide environmental simulation test equipment usually has a storage tray inside the test chamber, which is used to place the sample block that needs to be tested in the carbon dioxide environment simulation test. However, traditional carbon dioxide environmental simulation test equipment often uses a bolt-locking and limiting structure to connect the tray to the chamber wall. In practical use, when the height of the tray needs to be adjusted according to the actual size of different sample blocks, the operator needs to use tools such as wrenches to loosen the bolts before moving and adjusting the tray. After adjusting to the appropriate height, the bolts need to be tightened again to fix the tray. The entire adjustment process is cumbersome and complex, not only impossible to complete quickly by hand, but also time-consuming and laborious. In scientific research experiments, time is often very valuable, and this inefficient height adjustment method significantly reduces the ease of use of the equipment, thus affecting the experimental progress and potentially leading to inaccurate or incomplete experimental data. Therefore, this invention proposes a carbon dioxide environmental simulation test equipment. Utility Model Content

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.

[0015] Example 1 Please see Figures 1 to 5This is the first embodiment of the present utility model, which provides the following technical solution: a carbon dioxide environment simulation test device, including a carbon dioxide environment simulation test chamber 1, air inlets 6 disposed on both sides of the carbon dioxide environment simulation test chamber 1, a test chamber 2 opened inside the carbon dioxide environment simulation test chamber 1, and a door 4 mounted on the front surface of the carbon dioxide environment simulation test chamber 1 by hinge rotation. The above structures are all prior art and do not involve the technical improvement part of this application. For the specific structural principle, please refer to the existing patents with publication numbers CN215866695U, CN219758032U and CN220820025U, which will not be elaborated here. Also includes Multiple storage trays 5 are set inside the test chamber 2. Two vertical guide rails 3 are fixed on both sides of the inner wall of the test chamber 2. A sliding structure is provided between the storage trays 5 and the vertical guide rails 3. The sliding structure includes a T-shaped guide block 51 fixed on the side of the storage tray 5 and a T-shaped guide groove 31 opened on one side of the vertical guide rail 3. The T-shaped guide block 51 slides in the T-shaped guide groove 31, so that the subsequent operator can adjust the height of the storage tray 5 by sliding it up and down. And a plug-in quick-release structure 7 is provided between the storage tray 5 and the vertical guide rail 3. The plug-in quick-release structure 7 can realize quick and stable positioning after the height of the storage tray 5 is adjusted. The plug-in quick-release structure 7 includes a rectangular guide seat 71 fixed to the bottom surface of the storage tray 5, a side slide seat 72 slidably located outside the rectangular guide seat 71, a limiting plug 73 fixed to the side of the side slide seat 72 and transversely penetrating the rectangular guide seat 71, and multiple limiting plug holes 74 opened in the inner wall of the T-shaped guide groove 31. The end of 73 is inserted into one of the limiting holes 74, which can effectively and stably support the placement tray 5. When the limitation is released, the side slide 72 can be pushed by hand to move the end of the limiting block 73 out of the limiting hole 74, which can quickly release the limitation on the placement tray 5. This allows the operator to adjust the height of the placement tray 5 and the distance between the upper and lower placement trays 5 according to the actual size of the sample block, improving the ease of operation during adjustment and thus improving the efficiency of operation during the test.

[0016] In this embodiment, preferably, the top end of the T-shaped guide groove 31 is connected to the top surface of the vertical guide rail 3, and the bottom end of the T-shaped guide groove 31 is connected to the bottom surface of the vertical guide rail 3, so that the T-shaped guide block 51 can slide out from the top or bottom end of the T-shaped guide groove 31, thereby realizing the separation of the placement tray 5 from the vertical guide rail 3, which facilitates the subsequent disassembly and replacement of the placement tray 5 or appropriately increases the number of placement trays 5 to meet different test sample placement requirements.

[0017] In this embodiment, preferably, the surface of the rectangular guide seat 71 is provided with a guide opening 711 for the limiting insert 73 to pass through.

[0018] In this embodiment, preferably, the plug-in quick-release structure 7 further includes a locking structure, which is disposed between the side slide 72 and the storage tray 5.

[0019] In this embodiment, preferably, the top surface of the side slide seat 72 slides in contact with the bottom surface of the storage tray 5. The locking structure includes an inner groove 751 formed on the bottom surface of the storage tray 5, a spring 752 and a semi-circular telescopic locking block 753 installed in the inner groove 751, and a limiting slot 754 formed on the top surface of the side slide seat 72 corresponding to the semi-circular telescopic locking block 753. The top end of the semi-circular telescopic locking block 753 is movably installed in the inner groove 751 by the spring 752, and the bottom end of the semi-circular telescopic locking block 753 pops out into the limiting slot 754. This allows the side slide seat 72 to be locked and limited during daily use, ensuring the positional stability of the side slide seat 72 and the limiting block 73, and ensuring that the end of the limiting block 73 can be stably inserted into the limiting hole 74, thus ensuring the limiting support stability of the storage tray 5.

[0020] In this embodiment, preferably, the top end of the spring 752 is fixed to the top inner wall of the inner groove 751, and the bottom end of the spring 752 is fixed to the top end of the semi-circular telescopic block 753.

[0021] In this embodiment, preferably, a rectangular opening is provided on the bottom surface of the side slide 72, which facilitates the subsequent operation of the side slide 72 by the operator.

[0022] In summary, before using this device, the distance between the upper and lower storage trays 5 should be adjusted according to the specific specifications of the test sample block to be tested, which is to adjust the height of the storage tray 5. During adjustment, simply push the side sliding block 72 forcefully to the side, causing the bottom end of the semi-circular telescopic block 753 to be squeezed into the inner groove 751. This allows the side sliding block 72 to slide smoothly, causing the end of the limiting insert 73 to move out of the limiting insertion hole 74, thus quickly and manually supporting and limiting the storage tray 5. At this point, the storage tray 5 can be slid up and down, allowing the T-shaped guide block 51 to slide within the T-shaped guide groove 31, achieving height adjustment of the storage tray 5. Once the appropriate height is reached, simply push the side sliding block 72 back by hand, allowing the limiting... The end of the insertion block 73 can be inserted into the limiting insertion hole 74 at other positions, and the side slide 72 is pushed back to the side of the rectangular guide 71. The bottom end of the semi-circular telescopic block 753 is pushed into the limiting slot 754 by the spring 752, thus completing the engagement and limiting of the side slide 72 and the limiting block 73. The limiting block 73 provides stable support and limiting for the storage tray 5, and completes the rapid adaptive adjustment of the height of the storage tray 5. Then, the test sample to be tested is placed on the storage tray 5, the chamber door 4 is closed, the air inlet 6 is connected to the external carbon dioxide generator, and the device is started, so that carbon dioxide is sent into the test chamber 2 to contact the test sample, thereby conducting a carbon dioxide environment simulation test.

[0023] Example 2 Please see Figures 1 to 5 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but the difference is that a guide block 712 is fixed on the upper wall of the guide opening 711, and a guide groove 731 corresponding to the guide block 712 is opened on the top surface of the limiting insert 73. When the limiting insert 73 moves laterally, the guide block 712 will also slide in the guide groove 731. When the guide block 712 slides to one end of the guide groove 731 and can no longer slide, the limiting insert 73 can no longer be pulled out, which can prevent the limiting insert 73 from falling off and separating from the rectangular guide seat 71 during the subsequent adjustment process, and play the role of preventing guide detachment.

[0024] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
