Description
Technical field
The utility model relates to power industry service kit equipment technical field, is specifically related to a kind of electric power switch knob anti-misoperation protector.
Background technology
At present, when work about electric power personnel carry out maintenance repair and circuit repair is, when needing to be come by control cubicle, circuit disconnects, so that normally carrying out of service work, when being closed by switch knob, hangs warning sign above usually, remind related personnel, carry out service work, No switching on, ensure the life security of staff.But however, sometimes people can pay no heed to warning sign, touch switch knob conveniently, cause accident to occur, or encounter switch knob due to other work by mistake.Trace it to its cause, mainly stop switch knob to be pressed in default of compulsory measure.
In addition, when running into service work on a large scale, needing to carry a large amount of warning signs, causing certain burden and difficulty to staff.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of structure electric power switch knob anti-misoperation protector simple, easy to use.
The utility model adopts following technical scheme:
A kind of electric power switch knob anti-misoperation protector, it comprises installation base plate, be fixedly installed on the fixed sleeving on installation base plate, movable sleeve is placed in the push rod device in fixed sleeving, the locking module being fixedly installed on push rod device lower end and the warning sign be arranged in described push rod device, described installation base plate is fixedly installed the warning sign case for blocking warning sign, described locking module is in the inverted U that Open Side Down, described fixed sleeving is provided with for limiting the freely up and down movable jackscrew of described push rod device, described push rod device comprises upper push-rod, connecting rod and lower push-rod, upper push-rod is sheathed in fixed sleeving, lower push-rod lower end is fixedly connected with inverted U locking module top, the top and bottom of connecting rod are connected with upper push-rod and lower push-rod respectively by screw thread, and pass through the length of connecting rod adjustable push rod device.
Improve further as the utility model, described warning sign is provided with warning lamp.
Improve further as the utility model, the both ends, left and right of described locking module are provided with chamfering.
Good effect of the present utility model is as follows:
The utility model structure is simple, convenient and practical, is fixed and is arranged at position corresponding with switch knob on control cubicle, maintainer can be avoided to carry a large amount of suspended warning boards, greatly reduce the work load of electric power overhaul staff.What is more important, promotes locking module downwards by push rod device, and warning sign moves downward simultaneously, avoid warning sign case, outside being presented at, locking module moves downward and is placed in U-type groove by switch knob, effective restriction switch knob can not be pressed, and forces to realize security implementations.Even if related personnel does not note the content neglecting warning sign, also switch knob cannot be pressed, avoid misoperation, ensure that the life security of maintainer.
Push rod device can be threaded connection to adjust length, to adapt to the control cubicle of different size, the applicability of device is strengthened.
Warning sign can write caution slogan, but is not easy to arouse attention in night or the poor environment of light, arrange warning lamp can make the observability of warning sign and alarming effect better.
Chamfering is set at the both ends, locking module left and right of inverted U, it can be made to move down smoothly, thus holding switch knob, prevent its sharp keen angle from switch knob is damaged simultaneously.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation;
Accompanying drawing 2 is the utility model using state structural representation.
In the accompanying drawings: 1 installation base plate, 2 fixed sleevings, 3 warning sign cases, 4 warning signs, 5 upper push-rods, 6 connecting rods, 7 lower push-rods, 8 locking modules, 9 jackscrews, 10 warning lamps, 100 control cubicles, 101 switch knobs.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
A kind of electric power switch knob anti-misoperation protector as shown in accompanying drawing 1-2; it comprises installation base plate 1, the fixed sleeving 2 be fixedly installed on installation base plate 1, movable sleeve are placed in the push rod device in fixed sleeving 2, the locking module 8 being fixedly installed on push rod device lower end and the warning sign 4 be arranged in described push rod device; described installation base plate 1 is fixedly installed the warning sign case 3 for blocking warning sign 4; described locking module 8 is in the inverted U that Open Side Down, and the both ends, left and right of described locking module 8 are provided with chamfering.Described fixed sleeving 2 is provided with for limiting the freely up and down movable jackscrew 9 of described push rod device, unclamp jackscrew 9, push rod device can move vertically, thus drives warning sign 4 and locking module 8 to move up and down.Downward promotion, warning sign 4 can be made to depart from outside blocking and being presented at of warning sign case 3, and upwardly, warning sign 4 can reenter in warning sign case 3 and be blocked.
Described push rod device comprises upper push-rod 5, connecting rod 6 and lower push-rod 7, upper push-rod 5 is sheathed in fixed sleeving 2, lower push-rod 7 lower end is fixedly connected with inverted U locking module top, the top and bottom of connecting rod 6 are connected with upper push-rod 5 and lower push-rod 7 respectively by screw thread, and pass through the length of connecting rod 6 adjustable push rod device.Described upper push-rod 5, connecting rod 6 and lower push-rod 7 are coaxially arranged, and the diameter of upper push-rod 5 and lower push-rod 7 is greater than the diameter of connecting rod 6.
As shown in the figure, described warning sign 4 is provided with warning lamp 10, the back side of warning sign 3 arranges corresponding circuit board and power supply etc., and warning sign 4 or warning sign case 3 arrange the switching device controlling described warning lamp 10.
As shown in Figure 2, be fixedly installed on control cubicle 100 by this device by installation base plate 1, position is corresponding with corresponding switch knob 101, when carrying out service work, downward promotion push rod device, makes switch knob 101 be placed in locking module 8, avoids switch knob to be misused and press.Warning sign 4 avoids blocking of warning sign case downwards simultaneously, and with prompting related personnel, " No switching on, circuit has people to work ", is now locked upper push-rod 5 by jackscrew 9.After service work terminates, unclamp jackscrew 9, upwardly push rod device, make locking module 8 depart from switch knob 101, warning sign 4 enters in warning sign case 3 and is blocked simultaneously, now locks push rod device by jackscrew 9 again.
