Description
Technical field
The utility model relates to a kind of type transformer station door lock, belongs to box-type substation servicing unit.
Background technology
At present; be strayed in box change station to prevent someone; usual needs hang up padlock on door body; existing this structure occurs although can play the situation preventing someone to be strayed in box-type substation; but be exposed on the external because padlock is naked; attack by rainwater and sand and dust for a long time; padlock easily damages; even if redesign other door lock with outside protective covers; obturation effect is also barely satisfactory; and the door lock of general band protective cover, be difficult to find whether the state of padlock closes, and staff can be made to produce error.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of type transformer station door lock, and it is safe and reliable that it can ensure that it latches, and avoids the phenomenon of maloperation.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of type transformer station door lock, and it comprises:
Master lock, described master lock has master lock seat and turns, and turns and is rotatably installed on master lock seat, to be turned thus switch gate by rotation;
Secondary lock, described secondary lock has secondary lock seat and right angle turning-bolt lock, and right angle turning-bolt lock is arranged on secondary lock seat;
Interlock plate, one end of described interlock plate is flexibly connected with right angle turning-bolt lock, the other end of interlock plate is flexibly connected with turning, so that master key and secondary lock is in Interlock Status, when right angle turning-bolt lock is opened, described right angle turning-bolt lock drives interlock plate action, thus can make in master lock turn master lock unblank part effect under rotate in master lock seat.
Further, be hinged with on turning described in and be flexibly connected so that its two connecting rods driving locking bar mechanism to carry out locking a door with locking bar mechanism.
Further in order to large area the exposed part at outer side of door of master key and secondary lock can be reduced; available protecting lockhole avoids the invasion and attack by rainwater dust storm; ensure the effective use of type transformer station door lock, described master lock seat and/or secondary lock seat are hinged with the cover plate that can cover lockhole in the part near lockhole.
Further in order to avoid master lock seat hold-down screw causes the phenomenon that loosens by shearing force, the back of described master lock seat is provided with jam plate, described in turn being installed in master lock seat by jam plate.
Further, the master lock of described master lock part of unblanking is special handle, in being inserted and turned, thus drives to turn and to rotate on master lock seat by this special handle.
Further, described special handle is T-type structure.
After have employed technique scheme, secondary lock is interlocked to master lock by interlock plate, guarantees to latch safe and reliable, avoids the phenomenon of maloperation; In addition, master key and secondary lock all with cover plate energy available protecting lockhole avoid by rainwater dust storm invasion and attack, ensure the effective use of type transformer station door lock; Rational configuration design can not only large area reduce master key and secondary lock exposed in part outdoors, and reasonably mechanism design also ensure that the intensity of turning, the constraint reaction produced when enabling to bear lever operated, and turn be by jam plate spacing in master lock seat, so can effectively avoid master lock seat hold-down screw to cause loosening by shearing force.
Accompanying drawing explanation
Fig. 1 is the structural representation of type transformer station door lock of the present utility model;
Fig. 2 is the structural representation of special handle of the present utility model.
Detailed description of the invention
In order to make content of the present utility model more easily be clearly understood, below according to specific embodiment also by reference to the accompanying drawings, the utility model is described in further detail.
As shown in Figure 1, 2, a kind of type transformer station door lock, it comprises:
Master lock, described master lock has master lock seat 3 and turns 4, turns 4 to be rotatably installed on master lock seat 3, to turn 4 thus switch gate by rotation;
Secondary lock, secondary lock has secondary lock seat 9 and right angle turning-bolt lock 8, and right angle turning-bolt lock 8 is arranged on secondary lock seat 9;
Interlock plate 10, one end of interlock plate 10 is flexibly connected with right angle turning-bolt lock 8, the other end of interlock plate 10 4 to be flexibly connected with turning, so that master key and secondary lock is in Interlock Status, when right angle turning-bolt lock 8 is opened, described right angle turning-bolt lock 8 drives interlock plate 10 action, thus can make in master lock turn 4 master lock unblank part effect under in master lock seat 3 rotate.
As shown in Figure 1, turn described in be hinged with on 4 and be flexibly connected so that its two connecting rods 5 driving locking bar mechanism to carry out locking a door with locking bar mechanism.
As shown in Figure 1, master lock seat 3 and/or secondary lock seat 9 are hinged with the cover plate 2 that can cover lockhole in the part near lockhole.
As shown in Figure 1, the back of master lock seat 3 is provided with jam plate 1,4 being installed in master lock seat 3 by jam plate 1 of turning.
As shown in Figure 1, the master lock of master lock part of unblanking is special handle 11, is inserted turn in 4 by this special handle 11, thus drives to turn and 4 to rotate on master lock seat 3.
As shown in Figure 2, special handle 11 is T-type structure.
Locking bar mechanism can be locking bar mechanism conventional in prior art, right angle turning-bolt lock 8 and to carry key be also regular size, due to the reasonable Arrangement of master lock seat 3 and secondary lock seat 9, complete interlock by interlock plate 10, effectively can ensure that type transformer station door lock locking is safe and reliable.Interlock plate 10 is driven by rotating right angle turning-bolt lock 8 key, make it to be in unlocking condition, special handle 11 effectively could inject the lockhole of master lock seat 3, then just can rotate the drive of special handle 11 and turn 4, then drive link 5, complete unlocking action, because reasonable in design, type transformer station door lock in the on state, special handle and right angle turning-bolt lock 8 key all cannot take off, which avoid staff to make a fault, only have when locking bar is in the state that latches completely, special handle 11 just can take out, then key is rotated, interlock plate 10 is made to be in blocking, key just can be extracted, after special handle 11 takes out with key, cover plate 2 adjusts position by self gravitation, the lockhole of master key and secondary lock is effectively covered, foreign material are avoided to fall into lockhole, also lockhole internal construction is effectively protected.
Master lock seat 3, turn 4, the slider-crank mechanism of connecting rod 5 and locking bar composition, the rotation of special handle 11 is transformed into sliding up and down of locking bar, realizes locking a door function.Master lock seat 3 4-M6 screw is fixedly connected with door body, secondary lock seat 9 is fixed by right angle turning-bolt lock 8 and door body, embed door-plate and reserve square hole, turn 4 bear special lever operated time produce constraint reaction, turn 4 by jam plate 1 spacing in master lock seat 3, master lock seat 3 hold-down screw can be avoided to cause loosening by shearing force; Rely on interlock plate to realize interlock between major and minor lock, can ensure that type transformer station door lock latches safe and reliable.
Above-described specific embodiment; technical problem, technical scheme and beneficial effect that the utility model solves are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
