Description
Technical field
The present invention relates to a kind of for reducing the knob top cover of the active force on the operating element of switchgear, wherein
The knob top cover has with reeded shell.
Background technique
Switchgear, especially contactor and breaker have inconvenient operation from certain structure size, because of behaviour
The handle for having too small is designed as element, therefore, switching process must be consumed by means of the power of raising and be realized.Active force can
Reduced by extending handle.However there is problems, that is, it is no longer able to using existing accessory, because for the accessory
For need the size of existing operating element.
Receive to need to apply the active force improved based on too small handle arms so far.Only in certain equipment knot
The fixed handle arms prolongation built cannot be used for all device structure rulers based on identical component is used in structure size
It is very little.
Summary of the invention
Accordingly, an object of the invention is propose a kind of active force for reducing on the operating element of switchgear
Knob top cover, cover that all structure size realizes operating element facilitates operation, without that must adjust accessory.
According to the present invention, which passes through the knob top cover for reducing the active force on the operating element of switchgear
It realizes, wherein knob top cover has with reeded shell.Here, it is a feature of the present invention that knob top cover has fastening
Part designs as follows, i.e., when needed can dismantle knob top cover from operating element.
Knob top cover according to the present invention will not pre-install fixedly and with losing, however customer side can easily again
Secondary disassembly.Therefore the operating member being made of operating element and knob top cover preferably constructs in two style.Rotation according to the present invention
Button top cover can be borrowed by means of fastener such as grab, strip dog, gripper hook or at existing operating element via being bolted
Help bolt element to fix.In the form assembled occurred at this moment, operating member preferably has longer handle.By making
With screwdriver, knob top cover can be dismantled from operating element, so as to provide conventional operating element again.
For the construction of the multi-piece type of operating member, existing operating element is able to use as basic framework.Knob top
Lid preferably has multiple grabs and/or strip dog and/or gripper hook, is engaged in the corresponding slot of operating element.Knob
Top cover preferably incompletely includes operating element, but at rear portion, preferably in handle prolongation with the opening of notch shape.
Tool can be introduced into the opening in customer side, tool is, for example, screwdriver.By forming the profile of notch, knob top cover
Side wall squeezed remotely from one another when introducing screwdriver.Here, grab and/or strip dog and/or gripper hook are in drop out of gear
It closes, and knob top cover can be removed.
Active force is reduced by the longer handle of knob top cover, so that client needs smaller power to connect switch.
By the detachability of knob top cover, it is able to use the switch with existing accessory.
Improvement project according to the solution of the present invention proposes that knob design of cover is tool there are two arm and is connected in arm
Between region U-shaped.Groove is formed by U-shape configuration, operating element can be accommodated in the groove, so that knob top cover package behaviour
Make element.
Special design scheme according to the solution of the present invention proposes that the groove in knob top cover passes through arm and middle area
Domain is formed.Groove is for accommodating operating element.
Advantageous design scheme according to the solution of the present invention can be, fastening is constructed at intermediate region and/or arm
Part when needed can be removed knob top cover from operating element by the fastener.Fastener should be set as follows herein
Meter, i.e. knob top cover anti-lost and are removably attached at operating element.
Advantageous embodiment of the invention can propose, fastener be grab and/or strip dog and/or clamping piece and/
Or bolt element.
Other advantageous embodiment of the invention can propose, realized by means of screwdriver and set knob top cover from switch
It is dismantled on standby operating element.
The special design scheme of the present invention can be that knob design of cover is handle arms prolongation.
Advantageous design scheme according to the solution of the present invention can be that knob design of cover is the outer of operating element
Shell.
Extension scheme according to the solution of the present invention can be that knob top cover is made of plastics.
Advantageous embodiment according to the solution of the present invention can propose, knob design of cover for breaker and/or
The operating element of contactor.
Knob top cover according to the present invention is preferably designed for tool, and there are two the U-shapeds of arm and the intermediate region for being connected to arm.Rotation
The arm of button top cover is opposite each other, wherein arm can construct in parallel with each other or extend towards one another ground in end region overlapping
Construction.Recessed portion can be placed in the arm of knob top cover, with the protrusion for for example accommodating operating element.Operating element tool
There is substantially square switch knob, is preferably molded at concentric bottom.At concentric bottom, with switch knob
Oppositely construct cylindrical protrusion.The recessed portion in the arm of knob top cover can designed for accommodate operating element it is same in
The bottom of the heart.There are two opposed side wall preferably parallel to each other, the knob tops of U-shaped for the rectangular switch knob tool of operating element
The arm of lid is resisted against these side-walls.In addition, there are two other preferred opposed sides parallel to each other for rectangular switch knob tool
Wall a, wherein intermediate region by knob top cover in these side walls covers.Pass through two with the side wall of side wall parallel arrangement
Recessed portion is configured to shorter.Fastener can be in the engaging-in recessed portion to rectangular switch knob, and fastener is preferably grab, only
Dynamic hook or clamping piece, are arranged at the arm of knob top cover.Equally it can be considered that, the switch knob of operating element is by revolving
The side-walls of the intermediate region covering of button top cover have recessed portion, and fastener can be engaged in the recessed portion, and fastener is preferred
