Description
Technical field
The utility model relates to power transformation O﹠M field, especially a kind of unlock key overcoat of practicality.
Background technology
The five-prevention locking system of transformer station is most widely used general, the most practical measure that prevents electric misoperation at present.But in use there is certain defective in unlock key at present:
1, during execute-in-place, operating personnel need hand-held unlock key to open five can to operate after anti-lock, can be placed on after lockset is opened specially to be its position of designing, but unlock key but do not have suitable safe placement location.And operating personnel due to both hands need to carry out concrete operations can't hand-held key, arbitrarily be placed on key on framework often in execute-in-place, on ground or in the pocket of packing into, all make unlock key have the possibility of breaking, kick, clashing in above-mentioned situation.
2, in operating process, the random placement of unlock key causes operation site chaotic, has potential safety hazard.
3, in operating process, the random placement of unlock key causes operation site chaotic, operates nonstandard unitizing, and has virtually increased monitoring personnel's work load.
Summary of the invention
The purpose of this utility model be to provide a kind of reasonable in design, simple in structure, easy to use, can be with the practical unlock key overcoat of unlock key fixed placement.
The purpose of this utility model realizes by following technological means:
A kind of unlock key overcoat of practicality is characterized in that: comprise an outer body, a draw-in groove that is used for putting unlock key is made in the front of this outer body, and the back side of outer body arranges a magnet.
And described magnet is inlaid in the back side of outer body.
And one or more magic tapes are all installed on the limit, the left and right sides of described outer body.
Advantage of the present utility model and good effect are:
1, a draw-in groove that is used for putting unlock key has been made in the front of this unlock key overcoat, the back side has embedded a magnet, utilize magnet that unlock key is adsorbed on executable operations equipment other framework or shell, thus the possibility of having avoided hand to take unlock key to break, kick, clash into.
2, owing to using the placement that unlock key can fix in order after this overcoat, thus standard execute-in-place, reduced operational risk, alleviated the personnel's that guard work load.
3, this unlock key overcoat only uses in operating process, does not affect unlock key passback instruction and charging.
4, it is very simple and convenient, time saving and energy saving and solid and reliable that this unlock key overcoat adopts the mode of magic tape fixed solution lock key.
5, the utility model is that a kind of design is ingenious, make simple, cost is low, the unlock key overcoat of easy to use and practical function, this product has been used for reference the design concept of mobile phone shell, exist on the basis of defective in considering the on-the-spot use of unlock key, combine the framework of converting equipment, the shell of switchboard etc. is all the actual conditions of ferrous materials, increased a strong magnets in overcoat, utilize magnet that unlock key is adsorbed on executable operations equipment other framework or shell, not only the convenient operation personnel place and take off, and unlock key is in monitoring personnel's the visual field all the time simultaneously, also be convenient to the execution of control.
