Fig. 3 is that cover plate of the present utility model is covered in the structural representation on spline dish.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail:
As shown in Figure 1, Figure 2 and Figure 3, safe-guard door lock anti-theft opening apparatus of the present utility model, comprises towed electromagnet 5, latch 4, spline dish 1, fixed head 7 and remote control circuit 6.Towed electromagnet, latch, spline dish, fixed head and remote control circuit are placed in safe-guard door lock panel 11.Towed electromagnet is electrically connected with remote control circuit.The outer rim of spline dish is provided with the latch draw-in groove 2 suitable with latch appearance and size, and spline dish central authorities are provided with the key spline through hole 3 that for key insert suitable with the key of safe-guard door lock.One end of latch is fixedly connected on the draw bar of towed electromagnet, and the other end points to the latch draw-in groove of spline dish outer rim.Fixed head be provided with the spline disk activity chamber 9 suitable with spline dish appearance and size and with the suitable latch loose slot 8 of latch appearance and size, the bottom surface in spline disk activity chamber is provided with the key turns through hole 10 corresponding with key spline through hole, fixed head contacts with lock core, and the key turns through hole of fixed head so that key corresponding with lock core keyhole can insert lock core and can rotate.Spline dish is placed in the spline disk activity chamber of fixed head, is flexibly connected with fixed head.Fixed head is fixed in safe-guard door lock panel.
Safe-guard door lock anti-theft opening apparatus of the present utility model is arranged on the inside wall of safe-guard door lock panel, and electromagnet, remote control circuit and cover plate etc. are all fixedly connected on safe-guard door lock panel, and spline dish is connected with safe-guard door lock panel sidewall contact.Key in lock panel, is provided with a through hole corresponding with spline dish, so that can insert the key spline through hole of spline dish from safe-guard door lock panel.
Towed electromagnet comprise coil, magazine, iron core and be arranged on iron core and framework between spring.After towed electromagnet energising, drive and produce the action of drawing as the draw bar of iron core by the magnetic action power of electromagnet, produce certain stroke, after power-off, lean on the spring return of spring, after draw bar pulls, the latch being connected with draw bar is pulled away from latch buckling groove, and spring is compressed, after power-off, spring is because elastic acting force resiles, thereby driving draw bar recovers origin-location, and latch is snapped in latch buckling groove.
Latch is bolted or is welded to connect the draw bar of towed electromagnet.The internal diameter size of latch draw-in groove must be greater than or equal to the outside dimension that contacts the latch one end being connected with latch draw-in groove, be convenient to latch and snap in smoothly in draw-in groove, the quantity of latch draw-in groove be one above and be uniformly distributed in the outer rim of spline dish.
Key for anti-theft door lock generally comprises head and Handheld Division, generally has one section of transition part between head and Handheld Division, transition part and head measure-alike, but do not establish password tooth, while unblanking, transition part can not be inserted in lock core, so spline dish can be connected to transition part.If the transition part of key is flat shape, the key spline through hole in spline dish is also flat shape, if key head and transition part are semicircle, the shape of key spline through hole must be also semicircle, by that analogy, the size and dimension of certain key spline through hole also must meet key head and can all pass other shapes.
In remote control circuit, be provided with infrared signal transceiver, controller, power supply and wire etc.When remote controller sends after the infrared signal of unlock command, the infrared transceiver of remote control circuit receives infrared signal, is sent to controller, and controller is resolved infrared signal, then controls power supply to towed electromagnet energising.The magnetic of towed electromagnet can keep Preset Time length, as 10-30 second, make latch shift out latch draw-in groove, serve as Preset Time, latch draw-in groove can be put because the elastic acting force of spring pops into position, Preset Time can be that the parameter of adjusting controller obtains, and can certainly realize by shnt capacitor between the both positive and negative polarity of towed electromagnet.
Cover plate is arranged between lock core and safe-guard door lock panel, and covers on spline dish and latch, is bolted to connection safe-guard door lock panel.Because cover plate is with stopping dial rotation, key is inserted in the keyhole of lock core by key spline through hole and key turns through hole, the internal diameter of key turns through hole must be greater than the width of key, be convenient to key and rotate in key turns through hole, key turns through hole can be circular or other shapes.Latch loose slot is communicated with spline disk activity chamber, and the length of latch loose slot is less than the length of latch.By cover plate being set to fix the zone of action of spline dish and the zone of action of latch, avoid unlock staff to prize spline dish simultaneously and then get around spline dish and directly unblank, improve theftproof performance.
In addition, key turns through hole in fixed head is the lock core hole clipping suitable with antitheft door lock core appearance and size, be convenient to the key port end of lock core to snap in the lock core hole clipping of cover plate, the lock core that makes to be arranged on cover plate both sides is relative with spline dish, make the key spline lead to the hole site correspondence on keyhole and the spline dish on lock core, Key is accurately inserted in lock core, the position of simultaneously further securing cover plate, avoid cover plate to be prized, improved theftproof performance.
