Abstract
The utility model discloses an electromagnetic lock, specifically speaking are novel little consumption electromagnetic lock. The magnetic drum type hand wheel comprises a magnetic drum, a sheet armature, a hand wheel shaft, a hand wheel, an eccentric shaft, a connecting rod, a lock tongue, a bracket, a connecting rod pin, a coil spring and a lead. The electromagnetic clutch comprising magnetic drum, sheet armature, hand wheel shaft, hand wheel, bevel gear and elastic slide block is used in transmitting unlocking power, and this results in novel structure, high safety and reliability and low power consumption.
Description
The utility model discloses a kind of electromagnetic lock, specifically a kind of novel little power consumption electromagnetic lock.
Existing electromagnetic lock generally adopts dual mode to open and close.First kind is to adopt solenoid actuated dead bolt jump ring, and second kind is directly to drive dead bolt with motor.Above-mentioned two kinds of electric control lock method for opening and closing are used wider at present, but also exist following defective: at first, if adopt the method for Motor Drive dead bolt, required electric current is bigger, usually more than 80 milliamperes, have in addition reach 6 amperes, at this moment just need with external AC and in the dress high capacity cell standby; Secondly, electromagnet is as the dead bolt jump ring, easily because of extraneous vibration tripping, poor reliability.
The purpose of this utility model provides a kind of novel little power consumption electromagnetic lock, and it utilizes electromagnetic clutch, by the frictional force carry-over moment, need not directly to drive dead bolt, reaches the purpose that reduces power consumption.
In order to achieve the above object, the utility model adopts following means to realize.At first, the design electromagnetic clutch, this electromagnetic clutch comprises magnetic drum, sheet armature, hand wheel shaft, handwheel, Dou tooth and elastic slide block.In magnetic drum inside around the enamel covered wire of many numbers of turn as inductance coil, in coil, promptly produce powerful magnetic force later on by electric current, on the magnetic drum surface one elastic slide block is set, on sheet armature, have the Dou tooth.Sheet armature is disc, it and the tight adhesive of magnetic drum, and form the ratchet system of transmitting one-directional rotation moment with the lip-deep elastic slide block of magnetic drum.The circle centre position of sheet armature is opened a circular hole, and sheet armature is enclosed within on the hand wheel shaft, and the unlikely slip of combining closely.Hand wheel shaft is a cylindrical spillikin, and its another top is welded on the handwheel, and handwheel is a flat cylinder, makes the user easy to use.
The utility model has also designed connecting rod, link pin, eccentric shaft, dead bolt, support, disc spring.Eccentric shaft is arranged on the end face of magnetic drum, connecting rod is enclosed within on the eccentric shaft, there is a link pin to pass connecting rod near connecting rod one end, on link pin, be provided with disc spring, the link pin two ends closely are connected with support, and dead bolt is housed on the support, and support one end has slotted hole, hand wheel shaft is by the slotted hole on the support, and magnetic drum is connected with drive circuit by lead.Magnetic drum is cylindrical, and the connecting rod left end is enclosed within on the link pin on the support.
The utility model has the advantages that: (1) is low in energy consumption, and quiescent current is 0.1 milliampere, and operating current is 7.5 milliamperes, has realized little power consumption; (2) safe and reliable; (3) novel structure; (4) easy to use.
Below in conjunction with Figure of description and embodiment the utility model is further described.
Figure of description 1 is a concrete structure schematic diagram of the present utility model.
Figure of description 2 is the structural representation of the utility model electromagnetic clutch.
Number in the figure (1) is a magnetic drum; (2) be sheet armature; (3) be hand wheel shaft; (4) be handwheel; (5) be eccentric shaft; (6) be connecting rod; (7) be dead bolt; (8) be support; (9) be link pin; (10) be disc spring; (11) be lead; (12) be the Dou tooth; (13) be elastic slide block.
Embodiment
With reference to Figure of description 2, make and choose magnetic drum (1) respectively, sheet armature (2), hand wheel shaft (3), handwheel (4), inner at magnetic drum (1) around last many circle enamel covered wires, its surface is provided with elastic slide block (13), connect lead (11) in magnetic drum (1) side, on sheet armature (2), open Dou tooth (12), and sheet armature (2) is enclosed within hand wheel shaft (3) goes up and combine closely, hand wheel shaft (3) other end is welded on handwheel (4) surface, eccentric shaft (5) is arranged on magnetic drum (1) end face, connecting rod (6) right-hand member is enclosed within on the eccentric shaft (5), connecting rod (6) left end is enclosed within on the link pin (9), disc spring (10) is set on the link pin (9), pretty (9) two ends of connecting rod closely are connected with support (8) respectively, on support (8) one ends slotted hole is arranged, hand wheel shaft (3) is equipped with dead bolt (7) by the slotted hole on support (8) one ends on the support (8).Connect above-mentioned each parts, refer again to Figure of description 1 and debugged, become novel little power consumption electromagnetic lock at last.
