Description
Technical field
The utility model relates to a kind of protection pressing plate anti-misoperation tool.
Background technology
Protection pressing plate is also named protection in flakes, is bridge and the tie of protective device contact external wiring, and can the function and the action outlet that be related to protection normally play a role.
Fig. 1, shown in 2, for now conventional a kind of wire spring type pressing plate, it comprises base 1, handle 2 and wiring axle 3, two connection jaws are provided with in the middle part of base 1 end face, base 1 is respectively provided with a vacant hole 11 on the front and back, base 1 end face is arranged on by a connecting axle 21 in the middle part of handle 2, handle 2 is provided with two coordinate grafting plug with connection jaws on base 1, two wiring axles 3 are arranged on corresponding described connection jaws position, base 1 bottom surface, penetrate base 1 inside to be connected with described connection jaws, on handle 2 on plug inserted base 1 during connection jaws, pressing plate is in closure state, handle 2 extract and turn to make on it plug insert described idle hole 11 time, pressing plate is in off-state.
According to the difference of protection pressing plate access protective device secondary circuit position, protection pressing plate can be divided into defencive function pressing plate and the large class of output clamping two.The throwing that defencive function pressing plate achieves some function of protective device is moved back, and output clamping determines the result of protection act, and its closure state connects protective device and switch trip loop, and off-state then makes trip(ping) circuit and protective device isolate.
When power equipment is safeguarded, need to take necessary technical safety measures to protection pressing plate: namely when testing work, for preventing causing switch mis-jumping, needing to protect pressing plate to disconnect, protective device and switch trip loop are isolated.Meanwhile, for prevent protection pressing plate miscarry into, also need to protection pressing plate upper end close, can not be switched on even if make it be connected.If safety measure is not handled properly, the malfunction of protective device just may be caused even to cause personal injury, cause serious accident.
The anti-error measure of protection pressing plate conventional at present uses insulating tape to isolate as anti-misoperation tool.Although insulating tape draw materials very convenient, use flexibly, there is the problems such as easily come off, can not reuse, efficiency is low in practice.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of difficult drop-off, protection pressing plate anti-misoperation tool reusable and easy to use.
The utility model solves its technical problem by following technical solution: a kind of protection pressing plate anti-misoperation tool, described anti-misoperation tool adopts insulating material to make, comprise a square division board, the middle part of described division board one end is provided with groove, the connecting axle of groove width and wire spring type pressing plate is suitable, the edge of described division board both sides is relative is downwards provided with two cards, the base top surface width of the distance between two cards and wire spring type pressing plate is suitable, described groove is inner makes described anti-misoperation tool after being in place, cover the connection jaws of respective side on wire spring type pressing plate base top surface to described division board away from the distance of one end of described groove.
After the handle of wire spring type pressing plate is rotated to open position from make position, above-mentioned anti-misoperation tool is inserted between handle and base, the connecting axle of wire spring type pressing plate is placed in the groove of anti-misoperation tool, anti-misoperation tool is pushed and puts in place, two cards in anti-misoperation tool make anti-misoperation tool be stuck in the top of wire spring type pressing plate base, anti-misoperation tool is made to be shifted in the process of handle rotating wire spring type pressing plate or to come off, a connection jaws in wire spring type pressing plate base top surface respective side covers by the division board of anti-misoperation tool completely, even if make the handle of wire spring type pressing plate be misrouted to make position, also because wire spring type pressing plate cannot be made to close in the plug on handle cannot insert below it on base connection jaws, reach anti-error object.
Improve as to one of the present utility model:
Described division board is provided with away from one end of described groove the handle conveniently inserting or pull out described anti-misoperation tool.
Described handle is along one of the setting of division board edge flange protruding upward.
Described groove is inner curved adaptive with the connecting axle of wire spring type pressing plate, and two walls of described groove openend are provided with chamfering, so that the connecting axle of wire spring type pressing plate can be placed in described groove more easily.
Described anti-misoperation tool has red warning district.
Described anti-misoperation tool is the red, transparent structure adopting PP material to make.
Relative to prior art, the utility model has following beneficial effect: anti-misoperation tool difficult drop-off of the present utility model, easy to use, can effectively prevent staff from miscarrying into protection pressing plate; Anti-misoperation tool of the present utility model adopts insulating material to make, and guarantees that protection pressing plate live part insulation property are good, DC earthing situation does not occur; The utility model structure is simple, easy to use, can be recycled, and being conducive to increasing work efficiency reduces costs.
