Description

[Detailed description of the invention] This invention locks the extractor of a desk drawer or a mount for various instruments that can be freely extracted at the extracted position, and allows the drawer or mount to be freely extracted as needed. This invention relates to an extractor and locking device that can be attached to and detached from the device.

The terminal board of the measurement information acquisition device is connected to a large number of input wirings, and since it is necessary to replace the input wiring, it should be smoothly extracted from the outer casing and can be attached and detached freely. There is a need.

Further, since such a terminal board contains electronic components and the like inside, it is desirable to easily remove it from the outer casing in as quiet a manner as possible.

However, in conventional extractor and locking devices of this type, when extracting the extractor from the outer casing, the locking tool slips into the rail on the outer casing side that guides and supports the extractor, making it difficult to extract the extractor smoothly. Not only is it not possible to remove the extractor from the outer casing, but it is necessary to twist the extractor up and down a little to disengage it, or it is necessary to temporarily support the extractor with one hand to disengage it. It is unavoidable that a certain amount of vibration is applied to the dovetail extraction, and the extraction is extremely unstable since the extraction must be supported with only one hand when removed.

In consideration of the above points, this idea not only allows the extractor to be released quietly and easily without vibration while supporting the extractor with both hands, but also allows the locking tool to be attached to the rail on the outer casing side. It is an object of the present invention to provide an extracting and locking device which can smoothly extract an extract from an outer casing without slipping and can perform an extremely stable and quiet disengagement operation.
