Abstract
Description
Technical Field
[0001] The utility model relates to the field of laboratory testing equipment, in particular to an experimental oven for testing thin film materials. Background Art
[0002] An oven is a box-shaped device specifically designed to dehydrate, dry, heat-treat, or perform other thermal reactions on items through heating means. Ovens are widely used in multiple fields such as industrial production, scientific research, laboratory analysis, and food processing, playing a crucial role in the drying, curing, heat-treatment, disinfection, dehumidification, preheating, etc. of various materials, parts, products, or foods. Currently, the common trays in ovens are either hollow or solid. When a thin film material is placed on the tray and inserted into the oven for testing, since the bottom of the thin film material is in contact with the tray, uneven heating of the thin film material will occur. Content of the Utility Model
[0003] In order to solve the problem that the current common high-temperature resistance detection method is to place the thin film material on the tray and put it into the oven, and this detection method will cause uneven heating due to the bottom of the thin film material sticking to the tray, the utility model provides an experimental oven for testing thin film materials, which includes a housing, a heat preservation chamber, a heating source, and an oven door. A number of trays are arranged in the heat preservation chamber. There is a rectangular cavity in the middle of the tray, and symmetric clamping mechanisms are arranged on both sides of the rectangular cavity. By the combined use of the clamping mechanisms on both sides, the thin film material is fixed at the center of the heat preservation chamber. The structure of the clamping mechanism is that at least two support rods a are fixedly connected to one side of the rectangular cavity. The support rods a are fixedly connected through a number of support rods b. A number of through holes are opened on the support rods b. A slidable bracket passes through the through holes on the support rods b and is slidably connected to the support rods b. One end of the slidable bracket facing the middle of the rectangular cavity is provided with a clip. The clip is on the center line on one side of the rectangular cavity. Each support rod is made of a high-temperature resistant material. The clips on both sides clamp the thin film material to be tested for high-temperature resistance testing.
[0004] Preferably, a number of symmetric sliding grooves are arranged on both side walls of the heat preservation chamber, which is convenient for taking and placing the tray and has a limiting effect.
[0005] Preferably, on the side of the tray corresponding to the back of the heat preservation chamber, elastic pieces are arranged at both ends to prevent wear caused by accidental impact between the tray and the heat preservation chamber.
[0006] Preferably, heating sources are arranged at both the top and the bottom of the experimental oven to make the test materials heated evenly.
[0007] The beneficial effects are as follows: The slidable bracket is slidably connected to the support rod b. When the film material shrinks, the slidable bracket will move along with the film material, without affecting the observation of the deformation of the film material. The film material is fixed in the middle of the heat preservation chamber by the clips on both sides. Heating sources are provided at both the top and the bottom of the heat preservation chamber, so that the film material is evenly heated. A number of symmetrically arranged chutes are provided on both sides inside the heat preservation chamber, which is convenient for placing and removing the tray and can limit the tray within the chutes, preventing it from moving randomly. Elastic pieces are provided at both ends on the side of the tray corresponding to the back of the heat preservation chamber to prevent wear caused by accidental impact between the tray and the heat preservation chamber.
