Description
Technical field
The utility model relates to a kind of improvement of door latch structure, particularly relates to a kind of switchbox multifunctional lock.
Background technology
Switchbox equipment is the equipment being responsible for controlling electric energy, protection, conversion and distribution at low-voltage power supply system end, primarily of compositions such as electric wire, components and parts (comprising isolating switch, line breaker etc.) and casings.Distribution box lock, point small distribution case lock, outdoor cabinet type transformer station dedicated lock etc.The security requirement of small distribution case to lock is not high, and the operation of lock also need not be too complicated, and mainly prevent power supply unit from exposing, emergency episode occurs and unblanks conveniently, can use plane single-point lock, handle is upspring and can be opened chamber door; Outdoor cabinet type transformer station to lock safety higher, can 2 points, 3 locking cabinets add padlock outdoors, magnetic texure can pin protective cover.But the door latch structure of existing use improves door lock mechanism according to flow processs of unblanking such as simple insertion, rotation, unlatchings mostly, so no matter from safety or the opening ways of lock, all too tradition, also exists larger hidden danger.Therefore, for above aspect, need reasonably to improve prior art.
Utility model content
For above defect, the utility model provides a kind of for needing just can to open or close after key pressure the switchbox multifunctional lock that distribution box door, structure are simple, can improve chamber door security performance, to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of switchbox multifunctional lock, comprises key switch plate, lock core, and described key switch back centre is with insertion tube and lock core is inserted in this insertion tube inside; The other one end of this lock core is through movable sleeve; Lock core end is inserted in lock body centre bore; The lock core section cover be in lock body centre bore has spring and this spring wherein holds out against outside movable sleeve in one end; At lock body external surface mounting nuts; Lock dog is fixedly mounted outside next-door neighbour's nut.
The described spring other end holds out against in lock body inner bottom surface, and described lock dog external surface embeds screw.
Described key switch plate is outside with rotary handle; Described lock core front end face is with a conical section; Described lock dog stretches out an ear handle.
The beneficial effect of switchbox multifunctional lock described in the utility model is: by arranging key switch plate, this key switch strip has rotation, first presses, the rear function such as to turn, can be used for needs just can open or close after key pressure distribution box door, structure simply, chamber door security performance can be improved.
Accompanying drawing explanation
With reference to the accompanying drawings the utility model is described in further detail below.
Fig. 1 is the decomposition texture schematic diagram of switchbox multifunctional lock described in the utility model embodiment.
In figure:
1, key switch plate; 2, lock core; 3, movable sleeve; 4, spring; 5, lock body; 6, nut; 7, lock dog; 8, screw.
Detailed description of the invention
As shown in Figure 1, switchbox multifunctional lock described in the utility model embodiment, comprise key switch plate 1, lock core 2, centre, described key switch plate 1 back side is with polygon insertion tube and lock core 2 is inserted in this insertion tube inside, this lock core 2 in addition one end passes movable sleeve 3, lock core 2 end is inserted in lock body 5 centre bore, and the lock core 2 sections of covers be in lock body 5 centre bore have spring 4 and this spring 4 wherein holds out against bottom movable sleeve 3 in one end, and this spring 4 other end holds out against in lock body 4 inner bottom surface; Polygon insertion tube outside mentioned above is inserted movable sleeve 3 and coordinates with hexagonal hole in movable sleeve 3.
Correspondingly, at lock body 5 external surface mounting nuts 6, fixedly mount lock dog 7 outside next-door neighbour's nut 6 and this lock dog 7 external surface embedding screw 8.
Switchbox multifunctional lock described in above the utility model embodiment, using method is:
1. first, nut 6 is inserted in through after switchbox aperture of door in one end narrower for lock body 5, by nut 6, lock body 5 is fixed on electric door, spring 4 is inserted in one end larger toward lock body 5;
2. movable sleeve 3 is inserted in after, lock core 2 one end is through being connected with screw 8 after movable sleeve 3, spring 4, lock body 5 and lock dog 7 and fixing lock dog 7, lock dog 7 is fixed on lock core 2 one end by screw 8, firmly press forward after the interior hexagon of the outer hexagon insertion tube insertion movable sleeve 3 in centre, key switch plate 1 back side, after making the square face on the upper square opening cover upper lock core 2 of movable sleeve 3, rotate key switch plate 1;
3. the outer hexagon insertion tube in centre, key switch plate 1 back side coordinates the interior hexagon of movable sleeve 3 to rotate, the upper square opening of movable sleeve 3 and cover square face thereon are and then rotated, thus drive lock dog 7 to rotate, make the dead bolt on lock dog 7 that distribution box door is pinned.
The above-mentioned description to embodiment can understand and apply this case technology for the ease of those skilled in the art, person skilled in the art obviously can make various amendment to these examples easily, and General Principle described herein is applied in other embodiment and need not through performing creative labour.Therefore, this case is not limited to above embodiment, and those skilled in the art is according to the announcement of this case, and the improvement made for this case and amendment all should in the protection domains of this case.
