Description

Door lock assembly

Technical field

The utility model relates to field of lockset, is specifically related to a kind of improvement that is used for the door lock assembly of gate control system.

Background technology

The door lock assembly that is used for gate control system at present generally all adopts electrical control and realizes by the time-delay latch, all need to provide a triggering control signal could trigger the action of opening the door accordingly in the time of access door, need swipe the card or input password in the time of for example in access door outdoors, must just can go out by switch when going out.This door lock uses cumbersome, and is special when go out, must be by the button on door next door, and often unreliable when the person of going out is eager to go out, can not as door directly push the use inconvenience open when equally going out.

The utility model content

The utility model is at the defective of above-mentioned prior art, can let pass automatically when a kind of going out is provided, easy to use, simple in structure, simple installation, good reliability, highly sensitive door lock assembly.

In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of door lock assembly, it comprises lock housing, hoisting mechanism, ratchet and the ratchet that matches with ratchet, be provided with base in the described lock housing, described base is provided with can be along the slide in axial sliding of base, be provided with back-moving spring between described slide and the base, the middle part of described ratchet is articulated on the base, and the tip and the ratchet of described ratchet are oppositely arranged, one side of described slide links to each other with hoisting mechanism by pull rope, and the end of opposite side and described ratchet is hinged.

As further improvement of the utility model:

The middle part of described ratchet is provided with mounting hole, and the hinged place of described base and ratchet is provided with free bearing, is provided with the latch that passes mounting hole and can slide in mounting hole in the described free bearing;

Be hinged with rocking bar in the described lock housing, the end of described rocking bar and the end of ratchet are articulated on the described slide jointly;

The end of described base offers the chute that distributes vertically, described slide is provided with the slip positive stop strip, described slide is sheathed on the base, and described slip positive stop strip is slidedly arranged in the described chute, described back-moving spring is sheathed on the described base, and described back-moving spring one end is conflicted on base, and the other end is conflicted on slide;

Described pull rope is a wire rope.

The utlity model has following advantage: the utility model realizes that by ratchet and the ratchet that links to each other with the turning cylinder of door the distinctiveness of the opposite house direction of motion limits, and can let pass automatically when going out, and has easy to use, simple in structure, easy-to-install advantage.Ratchet is articulated on the free bearing by mounting hole, latch, makes that the motion amplitude of corresponding ratchet one end was bigger when ratchet take place to slide along with slide, breaks away from and the meshing relation of ratchet good reliability, highly sensitive when door lock assembly is opened easilier; Be hinged with the end of rocking bar and rocking bar and the end of ratchet in the lock housing and be articulated in jointly on the described slide, the sports rule of therefore whole ratchet part can not shake, collision etc. easily, good reliability, can prolong application life of door lock assembly; Slide construction between base and the slide is simple, installation is simple, easy to maintenance; Back-moving spring is sheathed on the base, and alignment is good, motion is more stable; Pull rope is a wire rope, and tensile property is good, and application life is longer.

The specific embodiment

As Fig. 1, Fig. 2 and shown in Figure 3, the door lock assembly of present embodiment comprises lock housing 1, hoisting mechanism 5, ratchet 2 and the ratchet 3 that matches with ratchet 2, be provided with base 4 in the lock housing 1, base 4 is provided with can be along the slide in axial sliding 6 of base 4, be provided with back-moving spring 61 between slide 6 and the base 4, the middle part of ratchet 2 is articulated on the base 4, and the tip of ratchet 2 and ratchet 3 are oppositely arranged, one side of slide 6 links to each other with hoisting mechanism 5 by pull rope 51, and the end of opposite side and ratchet 2 is hinged.

In the present embodiment, pull rope 51 is a wire rope.The middle part of ratchet 2 is provided with mounting hole 21, and base 4 is provided with free bearing 41 with the hinged place of ratchet 2, is provided with the latch 411 that passes mounting hole 21 and can slide in mounting hole 21 in the free bearing 41.Be hinged with rocking bar 7 in the lock housing 1, the end of the end of rocking bar 7 and ratchet 2 is articulated on the slide 6 jointly.Hoisting mechanism 5 is the elevator motor, and hoisting mechanism 5 is fixed in the lock housing 1 in the present embodiment, also hoisting mechanism 5 can be fixed on the body of wall in addition.

As shown in Figure 4 and Figure 5, the end of base 4 offers the chute 42 that distributes vertically, slide 6 is provided with slip positive stop strip 62, slide 6 is sheathed on the base 4, and slip positive stop strip 62 is slidedly arranged in the chute 42, back-moving spring 61 is sheathed on the base 4, and back-moving spring 61 1 ends conflict on base 4, and the other end is conflicted on slide 6.In the present embodiment, the main body of base 4 is cylindrical, as shown in Figure 6, slide 6 main bodys are circular, slip positive stop strip 62 makes when slide 6 is sheathed on the base 4 that along the radially setting of slide 6 annulus slip positive stop strip 6 can prevent to deflect between slide 6 and the base 4.

The operating principle of present embodiment is as follows: the door lock assembly of present embodiment is installed in when last, and ratchet 3 is coaxial fixing with the turning cylinder of door 8, and ratchet 3 can rotate 180 ° along with the turning cylinder of door 8.As shown in Figure 1, the tip of ratchet 2 is positioned the hook tooth root of ratchet 3 under the default conditions, and ratchet 2 does not limit ratchet 3 and does counterclockwise motion, but limiting ratchet 3 does clockwise motion.As shown in Figure 7, if from inside to outside open door 8, then door 8 turning cylinder drives ratchet 3 and does counterclockwise motion, because ratchet 2 does not limit the counterclockwise motion of ratchet 3, so ratchet 3 can rotate automatically, thereby can from inside to outside push open as traditional door.As Fig. 8 and shown in Figure 9, open door 8 if desired from outside to inside, then at first need by swiping the card or inputing modes such as password and trigger a control signal, by control signal control hoisting mechanism 5 tension pull ropes 51, slide 6 slides and compression reseting spring 61 to the left, slide 6 spurs the end of ratchet 2 left, the tip of ratchet 2 is along the meshing relation of the direction perk shown in the arrow, disengaging and ratchet 3, ratchet 3 can be done clockwise motion after ratchet 2 and ratchet 3 broke away from meshing relation, thereby door can be opened from the outside.In the present embodiment, hoisting mechanism 5 tension pull ropes 51 generally continue about 20 seconds, overtime back hoisting mechanism 5 discharges pulling force, door 8 drives ratchet 3 self-returns, the hook tooth root that the elastic force of back-moving spring 61 resets the tip of ratchet 2 to rest in ratchet 3 by slide 6, thus realize door 8 self-return lockings.

The above only is a preferred implementation of the present utility model, and protection domain of the present utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to protection domain of the present utility model.Should be pointed out that for those skilled in the art in the some improvements and modifications that do not break away under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
