Description

Technical Field

[0001] The utility model relates to the technical field of ovens, in particular to an oven with adjustable internal space. Background Art

[0002] An oven is a drying box. Depending on the dry material, the drying box is divided into two categories: electric blast drying box and vacuum drying box. It has been widely used in chemical, electronic communications, plastics, cables, electroplating, hardware, automobiles, optoelectronics, rubber products, molds, spraying, printing, medical, aerospace, colleges and universities and other industries. The huge market demand has led to the diversification of drying boxes and the structural quality of the products is also different. In order to make people understand the drying box more clearly, use a pair of discerning eyes to identify the quality of the drying box.

[0003] In a Chinese patent for an oven with conveniently adjustable internal space (patent number: CN215983620U), the device includes a box body, a box door is hinged on the front, a high-strength rectangular frame is embedded in the inner side of the limiting slot, and slide grooves are opened on both sides of the inner wall of the high-strength rectangular frame. A ball is arranged at the inner bottom of the slide groove, and an arc-shaped pressure rod is arranged at the inner top of the slide groove. A spring is arranged at the connection between the arc-shaped pressure rod and the slide groove, and a plurality of storage rods are arranged in the middle of the arc-shaped pressure rod and the ball. A folding extension is hinged between the adjacent storage rods. The retractable rod and the storage rod can carry and place objects or trays, and the foldable telescopic rod can facilitate the horizontal extension and retraction of the entire storage rod. The empty area after retraction can facilitate the natural upward extension of objects with higher sizes at the bottom, and the area with the storage rod can be used to place smaller objects, thereby achieving flexible adjustment in space. The high-strength rectangular frame mainly serves to limit and stabilize the storage rod and adjust the height. However, in this device, the adjustment of the two storage mechanisms still adopts a pull-out method, which is more troublesome to operate, inconvenient to use, and easy to be burned by high temperature.
