Detailed description of the invention
For the technical scheme making those skilled in the art be more fully understood that in the present invention, implement below in conjunction with the present invention
Accompanying drawing in example, is clearly and completely described the technical scheme in the embodiment of the present invention, it is clear that described reality
Execute a part of embodiment rather than whole embodiments that example is only the present invention.Based on the embodiment in the present invention, this
The every other embodiment that field those of ordinary skill is obtained under not making creative work premise, all should belong to
The scope of protection of the invention.
Refer to Fig. 1, the open a kind of air switch locking device of the embodiment of the present invention.Disclosed air switch lock
Determine device and include base 100 and threaded fastener 200.
Base 100 is made up of insulant, the most irregular triangular prism structure, as it is shown in figure 1, the end of base 100
Face is for being attached to the front panel 410 of air switch 400.Base 100 is provided with bayonet socket 110 and screwed hole 120, bayonet socket
110 and screwed hole 120 intersect.In the application, the shape phase of the shape of bayonet socket 110 and the handle 420 of air switch 400
Adaptive so that bayonet socket 110 can be located on the handle 420 of air switch 400.
Threaded fastener 200 coordinates with screwed hole 120, in threaded fastener 200 can extend bayonet socket 110 and air switch
Handle 420 end face of 400 offsets cooperation, to apply to make base 100 to fit before air switch 400 to base 100
The power that is adjacent to of plate 410, and then whole base 100 is fastened on the front panel 410 of air switch 400, the most just
Whole air switch locking device is fixed on the front panel 410 of air switch 400.This kind of situation, bayonet socket 110
The position contacted with handle 420 is equivalent to a fulcrum, along with the locking of threaded fastener 200 makes whole base 100
Rotate towards the direction being adjacent to front panel 410 for fulcrum with the position that bayonet socket 110 contacts with handle 420, and then realize whole
Fixing of individual locking device.
In air switch locking device disclosed in the embodiment of the present invention, joined with screwed hole 120 by threaded fastener 200
Conjunction realizes whole locking device and is fixed on the front panel 410 of air switch 400, now, and whole locking device and air
Switch 400 one entirety of formation, makes bayonet socket 110 and the common locked hand 420 of threaded fastener 200, it is impossible to right simultaneously
The handle 420 of air switch 400 implements any operation, is therefore avoided that in circuit maintenance process, enters handle 420
Row combined floodgate maloperation operates.Visible, air switch locking device disclosed in the embodiment of the present invention can solve to overhaul at circuit
In journey, air switch is easier to the existing security hidden trouble that closes a floodgate.
In order to improve the safety of locking device further, stop other people operation to threaded fastener 200 further, excellent
Choosing, locking device disclosed in the embodiment of the present invention can also include lockset 300.Lockset 300 is arranged on base 100,
For blocking screwed hole 120, and then it is avoided that other people pass through tool operation threaded fastener 200.
The kind of the lockset 300 that can realize closure screwed hole 120 has multiple.Referring again to Fig. 1, a kind of concrete reality
The mode of executing is: lockset 300 includes lock body 310 and dead bolt 320.Lock body 310 is fixed on base 100, is whole lock
The main body of tool 300, dead bolt 320 is arranged on lock body 310, and can stretch relative to lock body 310.Lockset 300 is in
During locking state, dead bolt 320 can stretch out relative to lock body 310, is in the position of closure screwed hole 120.Lockset 300
When being in released state, dead bolt 320 can bounce back relative to lock body 310, and then is in the position dodging screwed hole 120.
Operator realizes operation to lockset 300 by key, and then realizes dead bolt 320 and to the closure of screwed hole 120 or keep away
Allow.Concrete, lockset 300 can be drawer-lock.
It can be implemented closure at the entrance of screwed hole 120 by lockset 300, it is also possible at the middle part of screwed hole 120 to it
Closure.In order to improve safety, base 100 is internal can arrange receiving chamber, accommodate chamber by the perforation of lock body 310 with
Screwed hole 120 connects, and dead bolt 320 is positioned at receiving intracavity, and can extend in screwed hole 120 from perforation, and it is right finally to realize
The closure of screwed hole 120.This kind of mode can realize dead bolt 320, at the middle part of screwed hole 120, it be implemented closure so that
Dead bolt 320 is in the middle part of screwed hole 120 being difficult to be destroyed, and can improve stability and the safety of locking.Preferably,
Lock body 310 is built in receiving chamber, and the lockhole of lock body 310 is positioned at the outside of base 100, say, that lock body 310
By realizing and the connection of base 100 by the way of receiving intracavity is fixing, it is to avoid lockset 300 is disassembled from outside.
In locking device disclosed in the embodiment of the present invention, screwed hole 120 can include unthreaded hole section 121 and the spiral shell accepted successively
Stricture of vagina section.Thread segment can be easy to threaded fasteners 200 and screwed hole near bayonet socket 110, this kind of structure of screwed hole 120
The connection of 120, and then improve both joint efficiencies.
Refer to Fig. 2, bayonet socket 110 is for passing for handle 420, and final handle 420 is at threaded fastener 200 and card
The common effect of mouth 110 is locked, and in order to improve locking effect, the edge of bayonet socket 110 can be jagged edge 111,
Jagged edge 111 can increase the frictional force between bayonet socket 110 and handle 420.
Refer to Fig. 3, in the application, the head end of threaded fastener 200 can be most advanced and sophisticated 210, it is simple to handle 420
Be fixed.The tail end of threaded fastener 200 can arrange word opening or a cross open, it is simple to operator use
Screwdriver operation threaded fastener 200 coordinates with screwed hole 120.
Referring again to Fig. 1, disclosed in the embodiment of the present invention, the locking device of air switch can also include linking up with 500,
Hook 500 is arranged on base 100, is used for hanging warning sign.The layout of hook 500 can be more conveniently for operation
Personnel hang warning sign, do not have warning sign hang on handle 420 existing for the problem being easier to come off.Equally,
Hook 500 can be adopted and be made from an insulative material.
Herein, what each preferred version only emphasis described is different from other scheme, as long as each preferred version is not
Conflict, can combination in any, the embodiment formed after combination is also within category disclosed in this specification, it is considered to
Succinct to text, the embodiment with regard to no longer being formed combination individually describes herein.
The above is only the detailed description of the invention of the present invention, makes to skilled artisans appreciate that or realize the present invention.
Multiple amendment to these embodiments will be apparent to one skilled in the art, and as defined herein one
As principle can realize in other embodiments without departing from the spirit or scope of the present invention.Therefore, this
The bright the embodiments shown herein that is not intended to be limited to, and be to fit to and principles disclosed herein and features of novelty
The widest consistent scope.
