Description
Affiliated technical field:
The utility model relates to a kind of door leaf locking device of push-and-pull automatic door, relates in particular to a kind of push-and-pull induction automatic door machine shaft magnetic locking device.
Background technology:
The door leaf locking device of induction automatic door, tradition adopts electric mortise lock, its shortcoming is: the pin hole of the latch misalignment magnetic clasp plate of lock body, the failure that causes locking a door, or certain reason makes pin hole contact with latch, and its frictional force makes latch can not throw off pin hole, make the failure of opening the door, and the power of opening the door will make the pin hole latch that clashes, and make lock body quicken to damage.
Summary of the invention:
The purpose of this utility model is to provide a kind of can respond to automatic door machine shaft magnetic locking device to the push-and-pull that machine shaft is locked and opened.
The purpose of this utility model is to realize like this, described push-and-pull induction automatic door machine shaft magnetic locking device, comprise motor, gear, magnetic means and sucker, its design feature is that a machine shaft is respectively stretched out in the motor body both sides of motor, the machine shaft of motor body one side connects gear, motor body opposite side is provided with magnetic means, the machine shaft outer end of motor body opposite side is passed magnetic means and is exposed to the outer end of magnetic means, and the machine shaft outer end and a sucker of motor body opposite side are located by connecting; There is coil windings described magnetic means inside, and the exit of coil windings is electrically connected with a direct current power supply.
The purpose of this utility model also can be achieved through the following technical solutions, described push-and-pull induction automatic door machine shaft magnetic locking device, and its characteristics are that described sucker is the sucker that soft magnetic materials is made.Described push-and-pull induction automatic door machine shaft magnetic locking device, its characteristics are that described magnetic means becomes same integral body with the motor system.Described push-and-pull induction automatic door machine shaft magnetic locking device, its characteristics are that magnetic means is made individual components and the motor body is rigidly connected.Described push-and-pull induction automatic door machine shaft magnetic locking device, its characteristics are that described sucker is rigidly connected with the machine shaft of motor body opposite side or is connected do relative motion with the axis direction of the machine shaft of motor body opposite side.
The utlity model has following characteristics: use machine shaft magnetic locking device of the present utility model, with the phenomenon of avoiding locking a door failure or opening the door and fail, and the application life of effectively improving the magnetic locking device; During energising, it is big that magnetic means and sucker are held power tightly, and during no power, magnetic means and sucker suction just disappear; Have characteristics such as the power of locking a door is big, simple in structure, easy to use.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the plan structure schematic diagram of Fig. 1.
Fig. 3 is the structural representation that is contained in push-and-pull induction automatic door of the present utility model.
Among the figure: motor body 1, gear 2, magnetic means 3, sucker 4, the machine shaft 5 of motor body one side, the machine shaft 6 of motor body opposite side, groove 7, alignment pin 8.
The specific embodiment:
Below in conjunction with drawings and Examples structure of the present utility model and operating principle and the course of work are elaborated:
As Fig. 1, Fig. 2 and shown in Figure 3, the utility model comprises motor, gear 2, magnetic means 3 and sucker 4, its design feature is that a machine shaft is respectively stretched out in motor body 1 both sides of motor, the machine shaft 5 of motor body one side connects gear 2, motor body opposite side is provided with magnetic means 3, machine shaft 6 outer ends of motor body opposite side are passed magnetic means 3 and are exposed to the outer end of magnetic means, and machine shaft 6 outer ends and a sucker 4 of motor body opposite side are located by connecting; There is coil windings described magnetic means inside, and the exit A of coil windings and B are electrically connected with a direct current power supply; The sucker that described sucker 4 is made for soft magnetic materials.Described magnetic means 2 can be linked to be same integral body with motor body 1, or manufactures individual components and be rigidly connected with the motor body.Described sucker 4 is rigidly connected with machine shaft or is connected do relative motion with the axis direction of machine shaft.Generally on sucker, have groove 7, one alignment pin, 8 one ends place the groove 7 that has on the sucker, machine shaft 6 outer ends of the other end and motor body opposite side are fixed, like this alignment pin one end can be in groove the direction of principal axis of machine shaft move but can block sucker sucker is rotated with machine shaft, the purpose of doing like this is that machine shaft does not move, just sucker can be subjected to magneticaction to make sucker and machine shaft relative positioning at machine shaft to moving to reach to inhale mutually but do not break away from groove with magnetic means, and promptly sucker is connected do relative motion with the axis direction of machine shaft.Sucker and machine shaft just can be definitely fixing if machine shaft can move axially, and promptly sucker and machine shaft are rigidly connected.
Motor: be used for driving the motor of door leaf motion, when machine shaft rotates, by gear transmission campaign, drive belt movement, thereby belt drive the closure or openness of door leaf.
Magnetic means: there is coil windings magnetic means inside, when exit A, the B of coil windings connect dc source, produces electric current, thereby produces magnetic force.Magnetic means can become same integral body with the motor system, or manufactures individual components and be rigidly connected with the motor body.
Sucker: sucker and machine shaft can not be done radially relative motion, and machine shaft drives sucker and rotates, and sucker and machine shaft are rigidly connected or do relative motion with the axis direction of machine shaft.
Operating principle:
When door leaf was closed, coil windings exit A, B in the magnetic means connected dc source, and coil windings produces magnetic field, sucks sucker, and under the effect of external force, sucker and machine shaft can not rotate, thereby made door leaf locking.When disconnecting dc source, coil windings no current in the magnetic means, magnetic disappears, sucker demagnetization simultaneously, magnetic means and sucker break away from no suction, sucker and machine shaft do not have the magnetic force constraint and can rotate again, and the machine shaft of motor body one side connects gear and drives the door leaf motion again, reaches the unlatching door leaf.In device of the present utility model in order to work as magnetic means and sucker when breaking away from no suction, sucker leaves magnetic means at once makes sucker not have the frictional resistance rotation, generally can in sucker or magnetic means, be provided with spring body, general spring body one end be fixed on the other end in sucker or the magnetic means stretch out sucker or magnetic means outer can with relative magnetic means or sucker contact, the elastic force of spring body is less than the suction between sucker and magnetic means, be that coil windings in the magnetic means produces magnetic force and overcomes the elastic force that spring body struts and suck sucker, coil windings in magnetic means does not have magnetic force can not hold sucker, then the elastic force that struts of spring body throws off magnetic means and sucker not hold, and sucker is thrown off magnetic means and just can freely have been rotated with machine shaft.
