Abstract
The utility model provides a safety door locking device. A door lock 1 and draw plates 3 are arranged on a support frame 6, and the draw plates 3 are respectively connected to a bayonet catch 4, a bayonet catch 5, and a handle 2. After the door lock 1 is unlocked, the handle 2 extends outward under the action of springs 7, and buckles an opening door; After the door lock is locked, the handle 2 retracts inside the plane of a door 8, and forms closing state. The utility model has the advantages of anti-prizing function, locking prevention by mistake, simple structure, and strong practicability. The utility model is especially suitable for trunks made of iron.
Description
The utility model belongs to a kind of door locking device of office with the metal bin.
Existing office metal bin door locking device, on the surface of door the bigger door knob that takes up space is housed, perhaps resemble the handle of anchor shape, and give with bigger drawing part and to put, both all connect lock pin by a rotating disk, must hold door knob or handle during the locking of unlatching and rotate an angle and cooperate the lock core action, its complex structure, assembling disperses, operation inconvenience, poor safety performance.
The utility model provides a kind of simple in structure, highly versatile, pick-proof, anti-error lock, safe and reliable door locking device.
The utility model is installed on the support 6 by door lock 1 and arm-tie 3, arm-tie 3 connects lock pin 4,5 and handle 2 respectively, handle 2 is retracted in the plane with door and coincide after door lock closes, and door lock is opened the back will shake hands 2 to stretch out that to be convenient to fasten sliding door outside the plane of door unlimited under the effect of spring 7.
Accompanying drawing 1 is the utility model schematic appearance.
Accompanying drawing 2 is the utility model structural representation.
Below in conjunction with accompanying drawing the utility model is further described.
As shown in Figure 1, outward appearance of the present utility model is embedded in the plane, and door lock 1 is formed with telescopic handle 2, this moment, door lock was closed condition, handle 2 closely matches with door, and no bossing can be decorated on the surface of handle 2 according to the requirement of matter.
As accompanying drawing 2 is an embodiment of the present utility model.Support 6 is fixed on the back side of bin door 8, and door lock 1 arm-tie 3 springs 7 are installed in respectively on the support 6, and diagram is in locking states, and this moment, dead bolt 9 was located arm-tie 3, and handle 2 is retracted in the plane of door 8.When opening the door, key makes dead bolt 9 retractions.Arm-tie 3 counterclockwise rotates in the effect of spring 7, and lock pin 4,5 shrinks thereupon, and the door that runs through is separated with frame, and it is overhanging to promote handle 2 in arm-tie 3 rotations, fastens handle 2 then door is opened.The effect that overcomes spring 7 power when closing the door locking will shake hands 2 to advance and put in place, and key is stretched out dead bolt 9, and with arm-tie 3 location, lock pin 4,5 runs through door and with frame door lock closed.
The utility model with the Men Chengyi plane, so the pick-proof performance is good, forgets that after door is closed handle 2 is opening when locking behind the locking, can remind and lock, and is particularly suitable for retaining case cabinet, the safety cabinet safe handling.
