Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, concrete detailed description is further done to the utility model.
As shown in the figure, a kind of electronic lock for cabinet, comprise lock housing 17, electromagnet 13 is fixed with in lock housing 17, the moved end of electromagnet 13 is connected with latch hook lever 8, described latch hook lever 8 is hinged with lock housing 17, the side of lock housing 17 is provided with the door nose introducing port 19 corresponding with door nose 1, the side of door nose introducing port 19 is provided with pendulum fork 9 by a bearing pin 23, one end of pendulum fork 9 is provided with can carry out the locking groove of snap close with door nose 1, described bearing pin 23 is also provided with pendulum 4 and torsion spring 3 successively, one end of pendulum 4 and hinge, the other end of pendulum 4 be provided with one with the installation portion of the one end fits of torsion spring, installation portion described in the present embodiment is a breach being located at end, in practical application, installation portion also can be an also installing hole.Pendulum 4 is provided with towards the side of door nose introducing port 19 work plane matched with door nose, and the shape of this work plane can be arranged as required, and the present embodiment is set to curved surface.One end of described torsion spring 3 becomes a crotch to pendulum 4 and pendulum fork 9 lateral buckling, match with the breach being located at pendulum 4 end, thus make can interact between this end of torsion spring 3 and pendulum 4, make a side can drive the opposing party's rotating Vortex around bearing pin 26 rotates time.
Pendulum fork 9 is provided with a handle hole 22, the bending end matched with pendulum 4 of torsion spring 3 puts in this handle hole 22, thus in locking state, when torsion spring 3 move to contact with the internal diameter of handle hole 22 time, door nose 1 is pressed in the locking groove of pendulum fork 9 by the work plane of pendulum 4; Unblank in process, torsion spring 3 can be with movable pendulum to pitch 9 and be rotated counterclockwise, to be discharged by door nose 1.The lock-bit face 7 of the hook-type carrying out locking that can match with the latch hook being located at latch hook lever 8 one end is provided with at the other end of pendulum fork 9.
Preferably, the end being provided with the one end in lock-bit face 7 at pendulum fork 9 also arranges non-return cambered surface 10, this non-return cambered surface 10 can ensure the latch hook end that can support latch hook lever 8 in the whole process of unblanking, make latch hook end can not be sagging, thus the power can saved when locking, and this structure can ensure to there will not be jam in the process of locking, thus improves the dependability of electronic lock.
The moved end of described electromagnet 13 is electromagnetic draw bar 11, and the end outer circumference surface of described electromagnetic draw bar 11 is provided with the groove of annular, and described latch hook lever 8 is connected with the fit depressions of electromagnetic draw bar 11 by the open slot being located at its end.Described annular groove only needs lathe process, and a procedure can complete; Described latch hook lever 8 can adopt the mode of punching press to be once made up of sheet material, and compared with prior art various connected modes herein, this structure is not only processed simply, and easy for installation, reduces the cost of manufacture of whole electronic lock.
In order to judge the two states of opening and lock of electronic lock, in described housing 17, be also provided with microswitch 15, the pendulum fork pressure that pendulum fork 9 is provided with for triggering microswitch touches lug 14.
Described microswitch 15 clamps boss 20 by two microswitches be symmetricly set on relative two inwalls of lock housing 17 and is located at the microswitch positioning round table 21 that two microswitches clamp on boss 20 and is fixed setting.Particularly, the gap that two microswitches clamp boss 20 is consistent with the installation dimension of microswitch 15, two microswitches clamp on boss 20 and arrange two microswitch positioning round tables 21 respectively, and the diameter of microswitch positioning round table 21 is corresponding consistent with the installing hole on microswitch 15 with position.During such installation microswitch 15, as long as the installing hole of microswitch 15 is aimed at two microswitch positioning round tables 21, two of lock housing side panels are combined, have just installed.Install simple and convenient, use manpower and material resources sparingly.
Conveniently finely tune microswitch 15, in lock housing 17, the place corresponding to microswitch 15 is provided with peep-hole 18, can ensure lock housing need not be opened the fine setting work that just can realize microswitch 15 like this.
In order to make a nose 1 be convenient to adjustment position when mounted to adapt with the door nose introducing port 19 of electronic lock, the door nose installing hole 2 on door nose 1 uses elongated hole, as shown in Figure 4.
Of the present utility modelly treat that lock status as shown in Figure 1.Now pendulum 4 top under the twisting force of torsion spring 3 is pressed on the sidewall of lock housing 17, and pendulum fork 9 is also forced to lean against lock housing 17 adjacent sidewalls due to the effect being subject to torsion spring 3 one end crotch, puts the locking groove opening of fork 9 and overlaps with the door nose introducing port 19 in lock housing 17.Now, the non-return cambered surface 10 being located at locking face 7 end of pendulum fork 9 limits the sagging reset of latch hook end of latch hook lever 8, and the other end pressure electromagnetic draw bar 11 of latch hook lever 8, electromagnetic draw bar 11 is in the position of being obstructed and cannot ejecting.Microswitch 15 is in free state.
When locking, door nose 1 enters along the parallel direction of door nose introducing port 19, contacts with the work plane on pendulum 4, promotes pendulum 4 and turns clockwise around bearing pin 23.Meanwhile door nose 1 also enter into pendulum fork 9 locking groove in promote pendulum fork 9 turn clockwise around bearing pin 23, when putting the lock-bit face 7 on fork 9 and crossing the latch hook on latch hook lever 8, the pin joint of latch hook lever 8 around itself and lock housing 17 under the effect of electromagnetism steel tower spring 12 is rotated counterclockwise, lock-bit face on latch hook is overlapped with the lock-bit face 7 on pendulum fork 9, be in locking state, i.e. lockup state, as shown in Figure 2 and Figure 3.Now, under the effect of torsion spring 3, pendulum 4 has the trend be rotated counterclockwise, thus the work plane of pendulum 4 is contacted with door nose 1, so door nose 1, when putting the bidirectional force applying of fork 9 and pendulum 4, loses free activity space, be locked at securely in the locking groove of pendulum fork 9.The stress point that door nose 1 accepts the force of pendulum fork 9 and pendulum 4 in pendulum fork 9 locking groove is respectively the locking poiut 5 shown in Fig. 2 and compresses point 6.In this case, pendulum fork pressure is touched lug 14 and is oppressed microswitch 15 and close.
When unblanking from locking state, electromagnet 13 is energized adhesive, attract moved end electromagnetic draw bar 11 thus pull latch hook lever 8 to rotate clockwise, the lock-bit face be positioned on latch hook lever 8 latch hook moves up and discharges pendulum fork 9, pendulum fork 9 is owing to losing the stop of latch hook, start to be rotated counterclockwise under the effect of torsion spring 3 and pendulum 4, thus make a nose 1 shift out a nose introducing port 19, door is opened.
