Abstract
The present invention relates to a kind of relay status holding meanss, including relay and limiting plate provided with power switch, the mounting hole corresponding with the open position of power switch and closed position is equipped with the positive left and right sides of relay, the left and right ends of the limiting plate are connected by the open position or closed position both sides mounting hole of bolt and power switch, middle side part is provided with a spacing hole corresponding with power switch under limiting plate, and power switch is located in the spacing hole can not activity.The present invention be a kind of reasonable in design, production cost it is low, easy to make, using flexible relay status holding meanss, the present apparatus can be by the activity of limiting plate limit switch when circuit is repaired, other staff's service modes can be pointed out by indicator lamp simultaneously, so as to which the improper operation avoided because of staff triggers security incident, it is ensured that the safety of staff.
Description
Technical field
The present invention relates to electric power tool technical field, especially a kind of relay status holding meanss.
Background technology
Relay is connected in electric wiring, is used frequently as the power switch of production line or various equipment, is worked as circuit
During failure, power supply need to be closed and repaired, it sometimes appear that occurring because of imprudence power-on tight in maintenance process
The security incident of weight.
The content of the invention
, should it is an object of the invention to make up the deficiencies in the prior art part there is provided a kind of relay status holding meanss
Apparatus structure is reasonable in design, and the activity of power switch can be limited when circuit is repaired, while can pass through instruction device
Point out other staff's service modes.
The purpose of the present invention is realized by following technological means：
A kind of relay status holding meanss, it is characterised in that：Including relay and limiting plate provided with power switch,
The positive left and right sides of relay is equipped with the mounting hole corresponding with the open position of power switch and closed position, the installation
Hole each two is one group, and two mounting holes in one of which is open mounting hole, and it is separately positioned on power switch open position
The left and right sides put, two mounting holes in another group is close mounting hole, and it is separately positioned on power switch closed position
The left and right sides；Installed by bolt and the open position of power switch or closed position both sides the left and right ends of the limiting plate
Hole is connected, and middle side part is provided with a spacing hole corresponding with power switch under limiting plate, and power switch is located at the spacing hole
It is interior can not activity.
Moreover, being additionally provided with an indicator lamp and the button for controlling the indicator lamp open and-shut mode on described limiting plate.
Advantages and positive effects of the present invention are：
1st, the present apparatus installs limiting plate in the position that is turned on or off of relay, and limiting plate can ensure that relay power is opened
Closing can not be movable, so as to avoid the generation of power switch misoperation fault.
2nd, the present apparatus is additionally provided with indicator lamp and the button for controlling the indicator lamp open and-shut mode on limiting plate, when spacing
After plate is fixed, indicator lamp is opened by button, you can to play warning function.
3rd, the present invention is a kind of reasonable in design, production cost is low, easy to make, protected using flexible relay status
Hold device, the present apparatus can be by the activity of limiting plate limit switch, while can pass through indicator lamp when circuit is repaired
Other staff's service modes are pointed out, so as to avoid because the improper operation of staff triggers security incident, it is ensured that work
Make the safety of personnel.
Brief description of the drawings
Fig. 1 is the structural representation of relay.
Fig. 2 is the structural representation of relay and limiting plate.
Embodiment
Describe embodiments of the invention in detail below in conjunction with the accompanying drawings；It should be noted that the present embodiment is narrative, no
It is limited, it is impossible to which protection scope of the present invention is limited with this.
A kind of relay status holding meanss, including relay 1 and limiting plate 4 provided with power switch, in relay just
The left and right sides in face is equipped with the mounting hole 3 and 9 corresponding with the open position of power switch 2 and closed position, the mounting hole
Each two is one group, and two mounting holes in one of which is open mounting hole 3, and it is separately positioned on power switch open position
The left and right sides, two mounting holes in another group is close mounting hole 9, and it is separately positioned on a left side for power switch closed position
Right both sides.
Installed by the open position or closed position both sides of bolt 6 and power switch the left and right ends of the limiting plate
Hole is connected, and middle side part is provided with a spacing hole 5 corresponding with power switch under limiting plate, and power switch is located at the spacing hole
It is interior can not activity so that the state of relay is maintained, and prevents faulty operation.
An indicator lamp 7 and the button 8 for controlling the indicator lamp open and-shut mode are additionally provided with described limiting plate, works as limit
After position plate is fixed, indicator lamp is opened by button, warning function can be played.
The preferred embodiments of the present invention are the foregoing is only, as long as realizing purpose of the present invention skill with essentially identical means
Art scheme, is belonged within protection scope of the present invention.
