Abstract
The utility model discloses a low-voltage switchgear drawer door locking device, belonging to the field of a draw-out type low-voltage switchgear for electric power distribution. The locking device includes two door lock sets and a linkage assembly. Each door lock set includes a tapered end, a lock pin, a dead bolt and a rectangular lockhole. The linkage assembly includes two transmission pieces and a connecting rod. The locking device provided solves the linkage problem of two locks and brings convenience to the operation of the switchgear drawer.
Description
Technical field
The utility model relates to the architecture advances of the pull-out type drawer of low-voltage switch cabinet that power distribution uses, and particularly relates to the architecture advances of drawer of low-voltage switch cabinet door lock assembly.
Background technology
The panel of drawer of low-voltage switch cabinet is openable, lock panel after, when the drawer plug, the power of plug can pass to the lock on the panel.Said panel size hour, a lock just can carry the plug strength of drawer.When panel size was big, when particularly the size on short transverse was relatively large, lock was difficult to carry the plug strength with the balance drawer, just takes usually two locks are installed up and down, plays the effect that equilibrium scatters one's forces.Each like this unblanking all must open twice, and be very inconvenient.In order to make two lock interlocks, there is this case to produce then.
The utility model content
To the defective that exists in the prior art, the utility model provides a kind of drawer of low-voltage switch cabinet door lock assembly, uses this device can solve the problem of two lock interlocks.
For realizing above-mentioned purpose, the technical scheme of the utility model is:
A kind of drawer of low-voltage switch cabinet door lock assembly comprises two cover door lock external member and linkage units.
Said door lock external member mainly comprises tapered end, lock core, dead bolt, rectangle lockhole, screw and cyclic spring pad.Adopt nut that tapered end is fixed on the drawer panel; Be set with lock core in the tapered end, nearly lockhole one end of lock core is a quadrangular, and square hole is sleeved on the lock core and adopts a screw to connect in the dead bolt; The end face of nearly lock core one end of dead bolt is circular, and circumference is first-class to be arranged at intervals with four flanges.
Said linkage unit comprises two driver blades and a connecting rod.Said driver blade is a rectangle, and is provided with a breach, and the breach both sides are provided with two rectangle fixing holes.Driver blade has a rivet away from a jiao of breach, is connected with said connecting rod through this rivet.Said connecting rod can be that freely rotate in the center of circle with the rivet; Driver blade is installed between dead bolt and the tapered end, the flange on the circular end surface of two nearly lock core one ends of rectangle fixing holes embedding dead bolt on the said driver blade.Be set with a cyclic spring pad between tapered end and the lock core.
The usefulness of the utility model is:
When up and down arbitrary keyhole inserts key turns; Key drives lock core and rotates, and lock core drives dead bolt and rotates, and dead bolt is through the motion of driver blade drivening rod; Link motion drives the driver blade that does not insert a lock of key in addition and rotates synchronously, thereby makes that the dead bolt of two locks rotates synchronously up and down.Screw in or screw out the rectangle lockhole that is arranged in the drawer.Solved the problem of two lock interlocks.Operation brings convenience to switch cabinet drawer

The specific embodiment
Shown in Fig. 1 to Fig. 9 was arbitrary, a kind of drawer of low-voltage switch cabinet door lock assembly comprised two cover door lock external member and linkage units 2; Said door lock external member mainly comprises tapered end 11, lock core 12, dead bolt 13, rectangle lockhole 14, screw 16 and cyclic spring pad 17.Adopt nut 15 that tapered end 11 is fixed on the drawer panel 3; Be set with lock core 12 in the tapered end 11; Lock core 12 nearly lockhole 14 1 ends are quadrangular 121; Square hole 131 is sleeved on the lock core 12 and adopts a screw 16 to connect in the dead bolt 13, and the end face 132 of dead bolt 13 near lock core 12 1 ends is a circle, and circumference is first-class to be arranged at intervals with four flanges 133.
Said linkage unit 2 comprises two driver blades 21 and a connecting rod 22.Said driver blade 21 is a rectangle, and is provided with a breach 211, and breach 211 both sides are provided with two rectangle fixing holes 212.Driver blade 21 has a rivet 213 away from a jiao of breach 211, is connected with said connecting rod 22 through this rivet 213.Said connecting rod 22 can be that freely rotate in the center of circle with rivet 213; Driver blade 21 is installed between dead bolt 13 and the tapered end 11, the flange 133 on the circular end surface 132 of two rectangle fixing holes, 212 embedding dead bolts, 13 nearly lock core 12 1 ends on the said driver blade 21.Be set with a cyclic spring pad 17 between tapered end 11 and the lock core 12.
When up and down arbitrary keyhole 5 inserts key 4 rotations; Key 4 drives lock core 12 and rotates; Lock core 12 drives dead bolt 13 and rotates; Dead bolt 13 is through 22 motions of driver blade 21 drivening rods, and connecting rod 22 motions drive the driver blade 21 that does not insert a lock of key in addition and rotate synchronously, thereby make that the dead bolt 13 of two locks rotates synchronously up and down.Screw in or screw out the rectangle lockhole 14 that is arranged in the drawer.Solved the problem of two lock interlocks.Operation brings convenience to switch cabinet drawer.
