Specific embodiment
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, ordinary skill people
Member's every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
The present embodiment provides a kind of key locking devices referring to FIG. 1 to FIG. 4,；The key locking device includes successively folding
It is located at panel 1, the first sliding block 2 and the second sliding block 3 together；Wherein, fixed on the panel 1 there are six support columns 8, described
First annular slot and the second annular groove are disposed with along its axial direction on support column 8；Six support columns 8 are on the panel 1, edge
The longitudinally asymmetric of panel 1 is distributed as two rows；And it is connected between the transverse direction of the panel 1, two opposite support columns 8
Connection sheet 7.First sliding block 2 and the second sliding block 3 are respectively positioned between two rows of support columns 8, wherein the two of first sliding block 2
While being located in the first annular slot of column 8 supported on both sides, the both sides of second sliding block 3 are located at column 8 supported on both sides
In second annular groove；
The first lock 4, second lock 5 and third lock 6 are longitudinally also sequentially installed on the panel 1 along it；Wherein, described
One lock 4 and the second lock 5 are located at the left end of the panel 1, and the third lock 6 is located at the middle part of the panel 1；First lock 4
It is connect with the first sliding block 2 with the driver plate 9 of the second lock 5, the driver plate 9 of the third lock 6 is connect with the second sliding block 3；
In addition, left half of and right one side of something of the panel 1 offers the circular hole of two rows of parallelly distribute ons respectively, meanwhile, the face
Multiple hollowed out areas 13 are additionally provided on plate 1.Wherein, the circular hole of the left one side of something of the panel 1 is located at first lock 4 and the second lock
Between 5, the circular hole of right one side of something is located at the right side of third lock 6；Correspondingly, left half of and right one side of something of first sliding block 2
The circular hole of two rows of parallelly distribute ons is equally offered respectively；Meanwhile the driver plate 9 for third lock 6 is provided on first sliding block 2
First mobile hole 12；And second sliding block 3 then offers the strip-shaped hole 10 of twice parallelly distribute on, the right side half in its left one side of something
While offering the circular hole of two rows of parallelly distribute ons；Meanwhile group for first lock 4 and the second lock 5 is provided on second sliding block 3
The mobile Article 2 hole 11 of disk 9.
With the movement of first sliding block 2 and the second sliding block 3, on the panel 1, the first sliding block 2 and the second sliding block 3
Circular hole switch between dislocation and aligned condition.Everyone has 1 padlock to maintenance personal, when panel 1, the first sliding block 2, second are sliding
After the circular hole alignment of block 3, the padlock that maintenance personal can use oneself passes through the circular hole and locking of alignment, so that the device
In key cannot take out and rotate.
Concrete function logic are as follows: when three locks all do not have key on panel 1, panel 1, the first sliding block 2 and the second sliding block 3
On circular hole be obstructed；When the key in the first lock 4 and the second lock 5 while being inserted into and rotating 13 °, and third lock 6 does not have
When key, the circular hole of the left one side of something of panel 1 and the circular hole of the left one side of something of the first sliding block 2 are alignment, and the circular hole of right one side of something of panel 1 with
The circular hole of the first sliding block 2 and the right one side of something of the second sliding block 3 is obstructed；When the first lock 4 and the second lock 5 do not have key, third lock 6
In key insertion after be not able to rotate, and at this time on panel 1 on the circular hole of the right and left and the first sliding block 2 and the second sliding block 3
Circular hole is obstructed；When the key of three locks on panel 1 is entirely insertable lock core and rotates 13 °, panel 1, the first sliding block
2, the circular hole whole corresponding align on the second sliding block 3.
When left one side of something of the key locking device have one or it is more padlock, simultaneously right one side of something also have one or more padlock
When, the keys of three locks on panel 1 are not able to rotate and take out；When left one side of something of the key locking device has one or more
Padlock, and when right one side of something does not have padlock, the key in the first lock 4 and the second lock 5 cannot take out and rotate, the key of third lock 6
Rotation or taking-up can be inserted；When the key locking device it is left it is half of there is no padlock, and right one side of something has one or more padlock
When, the key of three locks is not able to rotate and takes out.
Key locking device in the present embodiment folds the panel, the first sliding block and the second sliding block that are located at together by setting,
And aperture is distinguished on panel, the first sliding block and the second sliding block；So that when pair in key insertion key locking device will be corresponded to
When answering lock core and rotating to predeterminated position, so that it may be locked the key locking device by padlock, so that only participating in
The owner of locking is unlocked jointly, and the key that can just will lock into the key locking device takes out, thus by mutual
Lock relationship will correspond to key lock, fundamentally prevent operator's maloperation or mistakenly entering into charged region from getting an electric shock.Compared to biography
The Warning board of system is reminded, and key locking device of the invention is safer more reliable.
