As long as all being protected by Patent Law in right of the present utility model.
As depicted in figs. 1 and 2, a kind of incoming line cabinet, including cabinet 1, cabinet 1 is formed by rectangular steel tube and Plate Welding, cabinet
Being fixed with square installing plate 2 on the inwall of body 1 one side, installing plate 2 is provided with knife-like switch, knife-like switch includes plug-in strip 4, plug-in strip
4 are hinged on the fixing seat of installing plate 2, and plug-in strip 4 is provided above the connection seat 7 of knife-like switch.When plug-in strip 4 engages with being connected seat 7
Time, knife-like switch closed communicating；When plug-in strip 4 and connection seat 7 depart from, knife-like switch is off, switch cubicle and external power source
Disconnect.The quantity of plug-in strip 4 and connection seat 7 is three, is equipped with insulating bar 5 between plug-in strip 4, and insulating bar 5 is hinged in plug-in strip 4
Portion, insulating bar 5 connects and has connecting rod 8, connecting rod 8 to drive plug-in strip 4 to rotate, it is achieved the disconnection of knife-like switch and connection.
In order to avoid knife-like switch disconnect or during connection plug-in strip 4 flap scope excessive cause in plug-in strip 4 and cabinet 1 other
Parts interfere, and also to avoid the electric spark that plug-in strip 4 produces during folding to the miscellaneous part in cabinet 1
Produce damage, isolation cover is set outside installing plate 2 and plug-in strip 4.Isolation cover includes the cover body 62 of a C-shaped, cover body 62 lower end
Opening wide, cover body 62 upper end is provided with top board 63, and C-shaped cover body 62 is provided with slide block 61 on the inwall of installing plate 2 both sides simultaneously,
Installing plate 2 both sides are provided with chute 21, and chute 21 is in installing plate 2 upper end, and is in communication with the outside, during installation, by cover body 62
The slide block 61 of wall snaps in the slide block 61 in installing plate 2, then to issuing slip, makes to conflict bottom slide block 61 and chute 21.This
The position of isolation cover can be preferably defined by sample, it is to avoid isolation cover in use comes off from installing plate 2.Simultaneously
Dismount more convenient, it is simple to safeguard.It is additionally provided with below installing plate 2 in horizontally disposed base plate 3, base plate 3 side and cover body 62
Conflict in portion.Cover body 62 can be completely enclosed by arranging of base plate 3, it is to avoid the electric spark produced during knife-like switch folding is in cover body 62
Injection.
Simultaneously the most as shown in figures 1 and 3, in order to avoid plug-in strip 4 be connected seat 7 in a disengaged condition owing to cabinet 1 is rushed
Hit, cause plug-in strip 4 occur swing again with is connected seat 7 occur turn on phenomenon.A hinged spring base 14 on installing plate 2, and
Spring 14 is set in the internal cavities of spring base 14, simultaneously a hinged block 15 on plug-in strip 4, and makes block 15 be plugged in
In spring base 14, and conflict with his spring 14.So under the effect of spring 14 power, the end of plug-in strip 4 can remain away from solid
Determine the trend of plate, prevent plug-in strip 4 from being connected owing to impacting and connecting seat 7, make knife-like switch conducting that electric shock accidents to occur.
In addition as in figure 2 it is shown, be horizontally disposed with power transmission shaft 10 outside cabinet 1, power transmission shaft 10 axis and the axis of connecting rod 8
Direction is vertical.Being additionally provided with eccentric pivoted arm 11 on power transmission shaft 10, eccentric pivoted arm 11 is provided with eccentric orfice, connecting rod 8 is hinged on
In eccentric orfice, connecting rod 8 can be driven when power transmission shaft 10 rotates to rotate, thus drive plug-in strip 4 to rotate the conducting realizing knife-like switch
And disconnection.It is further fixed on turbine 12 on power transmission shaft 10, below turbine 12, is provided with the worm screw 13 driving turbine 12 to rotate.Worm screw 13
It is provided with away from one end of cabinet 1 and is easy to transmission band hex slot.When turbine 12 rotates and drive rotary shaft rotation, eccentric pivoted arm 11
Rotate, connecting rod 8 axis moves, plug-in strip 4 be connected after seat 7 disengages or close, owing to turbine 12 worm screw 13 has self-locking merit
Can, unless rotary worm 13, otherwise plug-in strip 4 will not rotate under the effect of external force, can avoid further due to cabinet 1
Caused plug-in strip 4 to occur the phenomenon of maloperation to occur by impact, improve security performance.
The above is only exemplary embodiment of the present utility model, not for limiting protection model of the present utility model
Enclosing, protection domain of the present utility model is determined by appended claim.
