The prior art mechanical locks have complicated structures and thus the assembly works are also tedious so as to be labor-inefficient and not economical. Thereby electronic locks are developed to resolve the defects in the prior art. However the electronic locks still have the following defects. The prior art electronic locks cannot suit for doors of different widths. Thus various kinds of locks are designs for different doors. Furthermore, the prior art electronic locks only have the operation mode of opening as power is off and the opening mode as power is on so that the use of the lock is confined. Moreover, the prior art electronic locks cannot be used as a mechanic locks. When the electronic elements of the electronic lock are destroyed, the lock cannot be used. Furthermore, the prior art electronic locks have some disadvantages which are necessary to be improved.
Accordingly, the primary object of the present invention is to provide a magnetic lock, wherein the magnetic lock of the present invention is suitable for doors of various specifications. Furthermore, the magnetic lock of the present invention has an open mode in power-on state and a close mode in power-off state. Moreover, a pin serves to achieve the object of function setting. The magnetic lock of the present invention has the function of mechanical lock and electronic lock. The structure of the magnetic lock is simple and easy in maintenance with a longer lifetime and lower manufacturing cost.
To achieve the above object, the present invention provides an actuation portion formed by a magnetic tube, a movable post, a spring, a driving sheet and a connecting sheet; the magnetic tube being received with the movable post therein; a front end of the movable post being engaged to the spring; a front end of the movable post being formed with a slot for receiving a retaining hole of the driving sheet; the movable post being pivoted to the driving sheet by using a pin; the driving sheet being further extended with a first sub-section and the second sub-section which being formed with retaining holes, respectively. The first sub-section and the second sub-section being studded to first end and the second end of the connecting sheet, respectively; interiors of the first end and the second end being threaded for screwing the outer threads of the pin; the connecting sheet having a retaining hole; the connecting sheet further having the third end; a positioning seat having a slot at a rear end thereof for receiving the actuation portion and a circuit board; a slot being formed at a lower end of the positioning seat; an exterior of the positioning seat being formed with two via holes and a positioning hole for receiving a pin; the via holes being corresponding to the retaining holes of the driving sheet; the positioning seat being fixed to the retaining hole; a tongue embedded at the slot at the lower end of the positioning seat and being fixed to the third end of the connecting sheet; the tongue being movable within the positioning seat; a retaining seat having a displace unit; when the displace unit passes through a distal end of the movable post, the displace unit being clamped in the slot of the movable post by using a retaining ring for preventing the displace unit from falling out as the movable post moves; the movable post being movable in the retaining seat; the retaining seat having a slot; a core embedded into the slot of the retaining seat and to combine with the displace unit; thereby the movable post, driving sheet, connecting sheet and tongue being interconnected; a connecting plate; the positioning seat and the retaining seat being locked to the connecting plate; the connecting plate having a via hole; and a casing.
The various objects and advantages of the present invention will be more readily understood from the following detailed description when reading in conjunction with the appended drawing.
In order that those skilled in the art can further understand the present invention, a description will be described in the following in details. However, these descriptions and the appended drawings are only used to cause those skilled in the art to understand the objects, features, and characteristics of the present invention, but not to be used to confine the scope and spirit of the present invention defined in the appended claims.
With reference to
An actuation portion 1 is formed by a magnetic tube 11, a movable post 12, a spring 13, a driving sheet 14 and a connecting sheet 15. The magnetic tube 11 is received with the movable post 12 therein. A front end of the movable post 12 is engaged to the spring 13. A front end of the movable post 12 is formed with a slot 121 for receiving a retaining hole 143 of the driving sheet 14. The movable post 12 is pivoted to the driving sheet 14 by using the pin 83. The driving sheet 14 is further extended with a first sub-section 141 and a second sub-section 142 which are formed with retaining holes 144, respectively. The first sub-section 141 and the second sub-section 142 are studded to first end 151 and the second end 152 of the connecting sheet 15, respectively. Interiors of the first end 151 and the second end 152 are threaded for screwing the outer threads of the pin 84. The connecting sheet 15 has a retaining hole 154. The connecting sheet 15 further has the third end 153.
A positioning seat 2 has a slot at a rear end thereof for receiving the actuation portion 1 and a circuit board 9. A pin bank seat 92 may be added to the circuit board 9 for switching the opening mode in turning off and turning on. A slot is formed at a lower end of the positioning seat 2. An exterior of the positioning seat 2 is formed with two via holes 22 and a positioning hole 21 for receiving a pin 82. The via holes 22 are corresponding to the retaining holes 144 of the driving sheet 14. The pin 82 and the positioning seat 2 are fixed to the retaining hole 154.
A tongue 3 is embedded at the slot at the lower end of the positioning seat 2 and is fixed to the third end 153 of the connecting sheet 15. The tongue 3 is movable within the positioning seat 2.
A retaining seat 4 has a displace unit 41. When the displace unit 41 passes through a distal end of the movable post 12, the displace unit 41 is clamped in the slot of the movable post 12 by using a retaining ring 43 for preventing the displace unit 41 from falling out as the movable post 12 moves. The movable post 12 is movable in the retaining seat 4. The retaining seat 4 has a slot 42.
A core 5 is embedded into the slot 42 of the retaining seat 4 and to combine with the displace unit 41. Thereby the movable post 12, driving sheet 14, connecting sheet 15 and tongue 3 are interconnected. In the present invention, when the magnetic lock 100 is turned off, it still has the function of a mechanic lock. Since the core 5 is combined to the displace unit 41 which is further fixed to the movable post 12, when a key is used to rotate the core 5, a rotary arm 51 in the core 5 will be driven to rotate so as to move the displace unit 41 to drive the movable post 12. Then a front end of the driving sheet 14, the connecting sheet 15 and the tongue 3 will be driven so as to have the function of opening and closing.
A connecting plate 7 is included. The positioning seat 2 and the retaining seat 4 are locked to the connecting plate 7 by screws 81. The connecting plate 7 has a via hole 71. A buffer ring 72 is installed between the positioning seat 2 and the via hole 71 of the connecting plate 7.
A casing 6 is included.
