Description
Technical field
The utility model is related to switchgear technical fields, and in particular to a kind of upper and lower door interlock of switchgear.
Background technology
In electric power power transmission and transformation system, high-tension switch cabinet is that very important electrical equipment, switchgear must in electric system
Must have and improve reliable " five is anti-" function, to ensure the safe operation of the person and power grid.Gate interlock is base to switchgear up and down
In a set of interlock for preventing mistakenly entering charged chamber and being equipped between the preceding middle Xiamen Men Yuqian.The switchgear of no ground switch
In operation, preceding Xiamen is can to open at any time, in preceding, lower door-plate be there is no mechanical latching function, there are security risk, use
This set mechanical latching could open preceding Xiamen behind the door in may be implemented before must be turned on, carry out enabling maintenance, safeguard.
Utility model content
In view of the above-mentioned problems, the utility model provides a kind of cabinet door interlock, can realize adjacent door it
Between interlocking switch.
The purpose of this utility model is achieved through the following technical solutions：
The utility model, a kind of cabinet door interlock, including interlocking switch, interlocking latch, support member, reset spring part
And lockplate, the interlocking switch are located at described interlocking latch one end, the interlocking latch runs through the support member, the interlocking
The pin other end is inserted into the limit hole that lockplate is equipped with, and the reset spring part provides the potential energy for being detached from limit hole for interlocking latch, described
Interlocking switch drives the interlocking latch to shift to lockhole so that interlocking latch one end is locked with lockhole cooperation.
Further, the interlocking switch is cylindrical, and front end is equipped with circular conical surface or inclined-plane, described interlocking latch one end
Equipped with hemispherical interlocking plunger, the interlocking plunger is used for inconsistent with interlocking switch.
Further, the support member includes upper backup pad and lower supporting plate, and the support plate and lower supporting plate are equipped with
The through-hole that interlocking latch passes through.
Further, the bullet part is spring, and the spring pocket is on interlocking latch, lower end and lower supporting plate, the upper end
It is contacted with the upper limit part being located on interlocking latch, the interlocking latch lower end, which is located on the downside of lower supporting plate, is equipped with lower limit part.
Compared with the prior art, the utility model has the advantage of：Using this set mechanical interlocks, may be implemented necessary
Preceding Xiamen could be opened in before unlatching behind the door, enabling maintenance is carried out, safeguards, it is simple in structure so that cabinet door is opened or closed
It closes safer.
Description of the drawings：
Fig. 1 is the schematic side view of embodiment interlock；
Fig. 2 is the stereoscopic schematic diagram of embodiment interlock.
In figure：1- interlocking switches, 2- interlocking latches, 21- interlockings plunger, 22- upper limits part, 23- lower limits part, 3- support portions
Part, 31- upper supporting pieces, 32- lower support elements, 4- reset spring parts, 5- lockplates, 51- lockholes.
Specific implementation mode
A kind of interlocking device of switch cabinet, including interlocking switch 1, interlocking latch 2, support member 3, reset spring part 4 and locking
Plate 5, the support member 3 include upper supporting piece 31 and lower support element 32.Interlocking switch 1 is installed on preceding middle door, the upper branch
Support member 31 is mounted on preceding middle door, and the lower support element 32 is mounted on the middle partition board on preceding middle door between preceding Xiamen, locking
The dress lock of plate 5 is on preceding Xiamen.1 cylinder front end of the interlocking switch is equipped with circular conical surface.Interlocking switch 1 in some embodiments
Or other cylindricalitys, the front end such as triangular prism, square column may be alternatively provided as inclined-plane.The interlocking latch 2 is located at interlocking switch 1
The through-hole that upper supporting piece 31 and lower support element 32 are equipped with is run through in lower section, and 2 top of interlocking latch is equipped with interlocking plunger 21, the interlocking latch
First 21 is hemispherical, and hemisphere face and interlocking switch 1 are inconsistent.Being equipped between the upper supporting piece 31 and lower support element 3 resets
Bullet part 4, the reset spring part 4 may include tension spring, rubber ring, latch plate etc., and the present embodiment is that reset spring part 4 is compression spring.Institute
It states compression spring lower end to contradict on lower support element 32,22 lower contact of upper end and locating part, locating part 22 is connect with interlocking latch 2；Institute
State 2 lower end of interlocking latch and be located at the downside of lower supporting plate 32 and be equipped with lower limit part 23, the lower limit part 23 limit 2 lower end of interlocking latch from
Lower supporting plate 32 removes.The lockplate 5 is equipped with lockhole 51, and when interlocking latch 2 passes through lockhole 51, preceding Xiamen is lockable.
In before closing when door, interlocking switch 1 elapses forward, and front end circular conical surface is contacted with interlocking plunger 22, with interlocking
Pin 1 is pushed ahead, and circular conical surface pushes interlocking plunger 22 so that interlocking latch 2 moves down, and lockplate is inserted into 2 lower end of interlocking latch will
Front lower door lock is lived.When door is opened in current, interlocking latch 2 exits lockhole 51 in its lower end under the elastic force effect of reset spring part 4, front lower
Door unlock.
Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing
Shown in also be the utility model one of embodiment, actual structure is not limited to this.So if this field
Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, without creatively designing
Frame mode similar with the technical solution and embodiment, are within the scope of protection of the invention.
