Description

Technical Field

[0001] The utility model relates to the technical field of concrete curing, in particular to an intelligent curing box for a laboratory. Background Art

[0002] Existing concrete specimens generally need to be cured in a constant temperature and humidity curing box in a laboratory. The curing box adopts an advanced intelligent temperature and humidity control system, which can accurately command functions such as heating up, cooling down, and increasing humidity. For example, a constant temperature curing box for cement experiments disclosed in a Chinese patent with the authorized announcement number CN217098260U includes a curing box body. A plurality of placement racks are installed inside the curing box body. A screw rod is rotatably connected inside the curing box body and a sliding rod is fixedly connected. A slider is threadedly connected to the screw rod, and the slider is slidably connected to the sliding rod. The beneficial effects of the utility model are as follows: By a driving mechanism to drive the screw rod to rotate forward and backward reciprocally, thereby controlling the slider to reciprocally move left and right inside the curing box body. The water droplets on the top wall inside the curing box body are scraped by a scraping block inside the collection box, preventing the water droplets condensed from water vapor from dripping onto the cement specimen due to gravity and affecting the test results. The scraped water droplets fall into the inside of the collection box for collection. By starting a driving motor to drive the exhaust fan blade to rotate, the water vapor generated by the cement is inhaled into the inside of the side box through a through groove, thereby reducing the condensation of water droplets on the inner top wall of the curing box body.

[0003] However, in actual applications, the above-mentioned curing box still has the following deficiencies: When the above-mentioned curing box is in use, the concrete test blocks need to be placed on the placement racks inside the curing box. However, the door of the above-mentioned curing box is manually opened and closed and each layer of the placement rack is fixed. The experimenter holds the test block with one hand and opens the door with the other hand, there is a risk of the test block falling.
