A device status display board

Abstract

The invention relates to a device status display card, comprising a shell and an inner lining, the shell is a hollow cuboid structure with an upper half transparent and a lower half non-transparent and an open bottom surface, and two sides of the upper half of the shell are opposite to each other respectively. There are two vertical bayonet openings, which are a first bayonet opening and a second bayonet opening respectively, and the first bayonet opening and the second bayonet opening are communicated near the top surface of the casing; the inner lining is connected to the The shape and size of the outer shell are matched to the rectangular parallelepiped structure, and two sides of the top of the inner lining are respectively provided with cards, and the cards are clamped in the second bayonet so that the inner lining is integrally located in the outer shell, Or the card is clamped in the first bayonet, so that the upper half of the lining is located in the outer casing, and the lower half extends out of the outer casing through the opening on the bottom surface of the outer casing. The invention is simple to operate, saves time and cost, improves work efficiency, and can be operated in a narrow space at the same time, thereby enhancing its practicability.

Description

technical field [0001] The invention relates to a display sign for displaying equipment status, in particular to an equipment status display board. Background technique [0002] The status of some existing equipment, especially the pipeline valves, needs to be listed and indicated to avoid misoperation by personnel. There are two types of tags currently in use, one is a paper tag, which can only indicate one state; the other is a plastic tag that can be turned upside down, and two states can be marked by upside down. For paper tags, if the status of the valve switch changes, you need to untie the lanyard and replace a new valve status tag, which will increase the cost of a tag; for plastic tags that can be turned upside down, if the valve switch status changes, you don’t need to replace it A new valve status tag can be listed upside down, but there are the following problems: some pipeline valves are large or the valve’s operable space is too small, so the hanging chain is ...

Problems solved by technology

For paper tags, if the status of the valve switch changes, you need to untie the lanyard and replace a new valve status tag, which increases the cost of a tag; for plastic tags that can be turned upside down, if the valve switch status changes, you don’t need to replace it A new valve status tag can be listed upside down, but there are the following problems: some pipeline valves are large or the valve’s operable space is too small, so the hanging chain is not easy to remove, and can only be removed by unfastening the chain buckle , put the tag upside down and then hang the valve, the whole process takes 1 minute, if the operating space is small, it will take at least 5 minutes, and it may cause damage to the chain buckle
