Description

The cabinet type electronic lock of a kind of door

Technical field

The utility model relates to the electric lockset technical field, refer in particular to a kind of simple in structure, easy to use, be mainly used in the electronic lock on the cabinet drawer.

Background technology

Along with the development of lockset, increasing electronic lock in occasions such as hotel, hotels, except the electronic lock that utilizes the magnetic card unlatching, has also been used the relative simple electronic lock of some structures cashier's office in a shop at indoor drawer and door by widespread usage.Yet the reliability of cabinet door lock at present simple in structure is really relatively poor, and therefore, how developing cabinet door lock simple in structure, that cost is low and reliability is high becomes having of industry problem to be solved.

Summary of the invention

The cabinet type electronic lock of door that the purpose of this utility model is exactly provide at the deficiencies in the prior art part a kind of simple in structure, easy to use, reliability is high.

For achieving the above object, the utility model includes lock box, in lock box, be equipped with and control the motor that rotates and reverse by circuit, the output of motor is connected with worm screw, worm screw is by drive transmission device and gear wheel engaged transmission, one projection is arranged on the end face of gear wheel, in the rotating shaft of gear wheel, also be with transmission button spring and rotation driving lever, on the rotation driving lever, projection is arranged, after the assembling, projection on the gear wheel and rotation have projection to stagger mutually on the driving lever and are fastened between the two card end regions of transmission button spring, have and rotate draw-in groove that driving lever matches in the dead bolt rear end so that the rotation driving lever is stirred draw-in groove and realize that dead bolt opens, the action of locking.

After adopting said structure, during the utility model switch lock, after dead bolt slided and puts in place, the restriction shifting block of dead bolt side has triggered limit switch stopped operating motor, changeed down even motor sensitivity goes out affiliation a bit again, gear wheel driven rotary button spring rotates, the knob spring has an elastic buffer when transmitting torsion, therefore, this buffering has been alleviated the error of motor sensitivity, do not cause it to burn out, improved the reliability of electronic lock.In addition, adopt the rotation driving lever that dead bolt is carried out the action of switch lock, simple in structure, reliable transmission, parts are few, have reduced cost of production, and the present invention had compared with prior art both had characteristics simple in structure, easy to use, again than the reliability height of prior art.

The specific embodiment

Shown in Fig. 1-8, the utility model includes lock box 10, in lock box 10, be equipped with and control the motor 20 that rotates and reverse by circuit, the output of motor 20 is connected with worm screw 21, worm screw 21 is by drive transmission device 30 and gear wheel 40 engaged transmission, one projection 41 is arranged on the end face of gear wheel 40, in the rotating shaft 42 of gear wheel 40, also be with transmission button spring 50 and rotation driving lever 60, on rotation driving lever 60, projection 61 is arranged, after the assembling, there is projection 61 to stagger mutually on projection 41 on the gear wheel 40 and the rotation driving lever 60 and is fastened on two of transmission button spring 50 and block end 50a, between the 50b zone, have and rotate draw-in groove 71 that driving lever 60 matches in dead bolt 70 rear ends so that rotation driving lever 60 is stirred draw-in groove 71 and realize that dead bolts 70 open, the action of locking.The left and

right limit switch

81,82 that motor 20 is stopped operating also is housed in described lock box 10, is provided with a restriction shifting block 72 at the side of dead bolt 70, when sealed, restriction shifting block 72 triggers left limit switches 81, and when unblanking, restriction shifting block 72 triggers right limit switches 82.Described left and

right limit switch

81,82 is the fine motion trigger switch.Described drive transmission device 30 has been the pinion of decelerating effect.

When unblanking, the user is by the sensor circuit in the magnetic card circuits for triggering plate, control circuit rotates motor 20, transmission by worm screw 21, the transmission of drive transmission device 30 is slowed down, driving gear wheel 40 rotates, the projection 41 on gear wheel 40 surfaces drives a card end 50a of transmission button spring 50, make another card end 50b of transmission button spring 50 stir the projection 61 on rotation driving lever 60 surfaces after overcoming twisting resistance again, rotation driving lever 60 is rotated, rotation driving lever 60 is stirred the draw-in groove 71 of dead bolt 70 back, dead bolt 70 is realized unlocking action, and after dead bolt 70 slided and puts in place, the restriction shifting block 72 of dead bolt 70 sides had triggered right limit switch 82, motor 20 is stopped operating, change down even motor 20 sensitivity go out affiliation a bit, gear wheel 40 driven rotary button springs 50 rotate again, and knob spring 50 has an elastic buffer when transmitting torsion, therefore, this buffering has been alleviated the error of motor 20 sensitivity, does not cause it to burn out, and has improved the reliability of electronic lock.When needs closure electronic lock, as mentioned above, in like manner, motor 20 counter-rotatings realize sealed by above-mentioned steps.

As from the foregoing, the utility model has solved the difficult problem of prior art, and it is simple in structure, easy to use, its reliability is than prior art height, and very the aspect is adapted at using on drawer, door cabinet or the small-sized door.
