[0001] This utility model relates to the field of darkroom door control technology, specifically a darkroom door control structure. Background Technology

[0002] Darkrooms are widely used in many fields, such as photography, medicine, scientific research, and industrial testing. In these applications, darkrooms need to maintain specific environmental conditions, such as no light, no dust, constant temperature, and constant humidity. At the same time, strict control is required for personnel entering the darkroom to ensure that the environment inside the darkroom is not disturbed, so as to protect the safety and accuracy of the equipment, data, and experimental results inside the darkroom. Early darkroom door control mainly relied on simple mechanical locks. Although this method can achieve basic access control functions, it has many limitations. For example, the keys to mechanical locks are easy to lose or copy, and it is impossible to accurately record and identify the personnel opening the door, making it inconvenient to manage. Moreover, when the door is open, the person taking the item must avoid the door and manually open it, which is extremely inconvenient to use. Utility Model Content

[0003] The purpose of this utility model is to provide a control structure for a darkroom door, so as to solve the problems mentioned in the background art, which require avoiding the door when opening and are inconvenient to use due to the need for manual opening.

The outer surface of the second roller block is in contact with the outer surface of the nut. The second roller block is connected to a connecting piece.

[0006] By adopting the above technical solution, the first roller block can be easily installed on one side of the hanging rail, and the door panel can be easily inserted into the side surface of the first roller block. Then, the second roller block can be inserted into the interior of the first roller block and fixed, so that the first roller block and the second roller block can clamp and fix the door panel, which facilitates the installation of the door panel and makes maintenance convenient. At the same time, the second roller block can be quickly connected to the slider through the connecting piece.

[0007] Preferably, the outer surfaces of both ends of the fixing plate are provided with through holes, and the diameter of the through holes of the fixing plate is larger than the diameter of the screw.
