Description
Technical field
The present invention relates to the protection device of the precision equipments such as dispatch automated system server, work station, giant-screen, specially power-off protection apparatus.
Background technology
The precision equipment impact resistances such as dispatch automated system server, work station, giant-screen are poor; these precision equipments are often caused device damage by the impact of unexpected power-off, incoming call, and there are currently no a kind of effective device and these precision equipments can be carried out power-off protection.
Summary of the invention
The present invention is in order to the precision equipments such as dispatch automated system server, work station, giant-screen are by the flimsy problem of impact of unexpected power-off, incoming call, it is provided that power-off protection apparatus.
The present invention adopts the following technical scheme that realization: power-off protection apparatus, including drive link, the body of rod at the middle part of drive link be hinged on be vertically fixed on power switch on jointed shaft in the plane, on the turning handle of the power switch that one end of drive link rides over precision equipment, the other end of drive link and the top of spring are fixed, the bottom of spring be fixed on be vertically fixed on power switch on level board in the plane, it is fixed with iron block on the body of rod between jointed shaft and the spring of drive link, the lower section of iron block be provided be fixed on power switch electromagnet in the plane, the terminals of electromagnet and the end of incoming cables of power switch connect.
When the power switch of precision equipment closes, turning handle is the top position of power switch, when the power supply of precision equipment is normal, electromagnet obtains electric and then attracts the iron block on drive link, one end just compression spring fixing with spring on drive link, spring is in compressive state, when the unexpected power-off of the power supply of precision equipment, electromagnet dead electricity, under the restoring force effect of spring, one end fixing with spring on drive link is rotated up, one end that the turning handle with power switch of drive link contacts rotates down, the turning handle of power switch is pushed the lower section of power switch, accordingly even when the supply line of precision equipment sends a telegram here suddenly, the supply line of precision equipment is also off state, therefore precision equipment will not be by unexpected power-off, incoming call impact and damage；After supply line's incoming call of precision equipment, electromagnet obtains electric, and then continues to attract the iron block on drive link, one end just compression spring fixing with spring on drive link, spring energy-storage, after waiting until the next time of power-off suddenly, spring transfers energy to drive link so that drive link disconnecting power switch；Equipment is artificially started by staff after incoming call.
The power-off protection apparatus that the present invention provides enables to the power switch of precision equipment and disconnects after unexpected power-off, and then makes precision equipment from unexpected power-off, the impact of incoming call.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
In figure: 1-drive link, 2-jointed shaft, 3-turning handle, 4-power switch, 5-spring, 6-level board, 7-iron block, 8-electromagnet.
Detailed description of the invention
Power-off protection apparatus, including drive link 1, the body of rod at the middle part of drive link 1 be hinged on be vertically fixed on power switch on jointed shaft 2 in the plane, on the turning handle 3 of the power switch 4 that one end of drive link 1 rides over precision equipment, the other end of drive link 1 and the top of spring 5 are fixed, the bottom of spring 5 be fixed on be vertically fixed on power switch on level board 6 in the plane, it is fixed with iron block 7 on the body of rod between jointed shaft and the spring of drive link 1, the lower section of iron block 7 be provided be fixed on power switch electromagnet 8 in the plane, the terminals of electromagnet 8 and the end of incoming cables of power switch connect.
