Abstract
A safety door lock without a keyhole comprises a lock head, a lock head guiding pipe, a resetting spring, a mechanical transmission connecting rod, a balanced pushing connecting rod, a connected pushrod motor round pipe, a push rod motor, push rod motor slideways, motor slideway frames, wherein the lock head penetrates through the lock head guiding pipe and is fixed on the mechanical transmissionconnecting rod, the resetting spring is sleeved outside the lock head between the locking head guiding pipe and the mechanical transmission connecting rod, the balanced pushing connecting rod is fixed on the left side of the mechanical transmission connecting rod, the connected push rod motor round pipe is fixed on the middle portion of the balanced pushing connecting rod, the fixed connected push rod motor round pipe is connected with the push rod motor, two sides of the push rod motor are provided with push rod motor slideways, the motor slideway frames are arranged in the push rod motor slideways, and the middle portions of the motor slideway frames are fixed with the left end socket of the push rod motor. The safety door lock has the characteristic of none keyholes, thereby stealers can not open the door lock through the keyhole, and the safety door lock achieves the safe and burglar-proof effect.
Description
Technical field
The utility model relates to a kind of lock, relates in particular to a kind of no keyhole safety door latch.
Background technology
At present, door lock generally comprises lock ﹠ key two parts.The lock of installing on door all has keyhole, when opening the door, key is inserted the switch of keyhole control gate.Present this lock, bad person inserts keyhole by various tool (such as master key) just can open door lock, has brought unsafe hidden danger to house-owner.
The utility model content
The technical problems to be solved in the utility model provides a kind of no keyhole safety door latch; This door lock has the characteristics of no lockhole, makes bad person no longer can open door lock by keyhole, reaches safe, antitheft effect.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: it comprises that tapered end, tapered end conduit, back-moving spring, machine driving link rod, balance promote link rod, connect push-rod electric machine pipe, push-rod electric machine, push-rod electric machine slideway and motor slideway frame; Described tapered end passes the tapered end conduit and is fixed on the machine driving link rod, and the tapered end between described tapered end conduit and the machine driving link rod is arranged with back-moving spring outward; The left side stable equilibrium of described machine driving link rod promotes link rod, the middle part that this balance the promotes link rod push-rod electric machine pipe that is fixedly connected, and this be fixedly connected push-rod electric machine pipe and push-rod electric machine are fixed; The both sides of described push-rod electric machine are provided with the push-rod electric machine slideway, are provided with the motor slideway frame in this push-rod electric machine slideway, and this motor slideway frame middle part is fixed together with push-rod electric machine left end head.
Further, left side, described motor slideway frame middle part also is provided with standby push-rod electric machine, and this standby push-rod electric machine is fixed on the square tube of a body.
Further, the both sides of described machine driving link rod all are provided with balance slide bar and the fixed mount that is used to control mechanical drive link running orbit, and described balance slide bar is in fixed mount.
The utility model operating principle is as follows: door all is to finish by positive and negative the transferring of push-rod electric machine when locking or unblanking, push-rod electric machine is at the machine driving link rod that promotes to be equipped with 3-5 tapered end, make tapered end insert in the doorframe or the release doorframe, to reach the purpose of locking a door and unblanking.In order to reach the purpose of real safety, two push-rod electric machines have been adopted, first push-rod electric machine is contained on the slideway, the fixed mount of second push-rod electric machine and first push-rod electric machine connects and is fixing, second push-rod electric machine is fixed on the integral support, so only use first push-rod electric machine when normally using, damage as first motor, use second motor by Electronic Control, second motor promoting first push-rod electric machine, and first push-rod electric machine slides to preceding in slideway and reach the purpose of locking a door in the same old way so.
The utlity model has following beneficial effect: have the characteristics of no lockhole, make bad person no longer can open door lock, reach safe, antitheft effect by keyhole.
Description of drawings
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to shown in Figure 1, the utility model comprises that tapered end 1, tapered end conduit 2, back-moving spring 3, machine driving link rod 4, balance promote link rod 5, connect push-rod electric machine pipe 6, push-rod electric machine 7, push-rod electric machine slideway 8 and motor slideway frame 9; Described tapered end 1 passes tapered end conduit 2 and is fixed on the machine driving link rod 4, the tapered end 1 outer back-moving spring 3 that is arranged with between described tapered end conduit 2 and the machine driving link rod 4; The 4 left side stable equilibriums of described machine driving link rod promote link rods 5, the middle part that this balance the promotes link rod 5 push-rod electric machine pipe 6 that is fixedly connected, and this be fixedly connected push-rod electric machine pipe 6 and push-rod electric machine 7 are fixing; The both sides of described push-rod electric machine 7 are provided with push-rod electric machine slideway 8, are provided with motor slideway frame 9 in this push-rod electric machine slideway 8, and these motor slideway frame 9 middle parts and push-rod electric machine 7 left end heads are fixed together.
Left side, described motor slideway frame 8 middle parts also is provided with standby push-rod electric machine 10, and this is fixed on the square tube 11 of a body.
The both sides of described machine driving link rod 4 all are provided with balance slide bar 12 and the fixed mount 13 that is used to control mechanical drive link 4 running orbits, and described balance slide bar 12 is in fixed mount 13.
Obviously, the foregoing description of the present utility model only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here can't give exhaustive to all embodiments.Everyly belong to the row that conspicuous variation that the technical solution of the utility model extends out or change still are in protection domain of the present utility model.
