As shown in Figure 1, the magnet axis 1 is a rod-shaped component. One end of the magnet axis is a columnar axis adapted to bump electronic components to achieve the function of locking and unlocking. The other end of the magnet axis is provided with a hole for connecting with the rod 6 that is subsequently connected to the actuation element 3. The magnet axis 1 is sleeved with a spring 2.

As shown in Figures 3a and 3b, the actuation element 3 is mounted in the opening 4.4 of the latch base 4. One end of the actuation element 3 is an actuation head 3.3, while the other end is a connecting portion 3.5. The actuation head is trinacriform and provided with a recess 3.4. The connecting portion 3.5 is provided with a first hole3.1 and a second hole 3.2, and the third cylindrical pinl3 is installed in the first hole 3 and crosses the connecting portion 3.5. Two ends of the third cylindrical pin 13 are inserted into two side holes 4.3 of the latch base 4 in order to position the actuation element 3 and allow the actuation element 3 to rotate around the fulcrum. The connecting portion 3.5 is further provided with a slot 3.6 for disposing the connecting rod 6.

The second cylindrical pin 12 is inserted into the second hole 3.2 in order that the connecting rod 6 and the actuation element 3 can rotate around the second cylindrical pin 12.

The connecting rod 6 is connected between the magnet axis 1 and the actuation element 3.The two ends of the connecting rod 6 are provided with two holes for mounting the first cylindrical pin 11 and the second cylindrical pin 12 respectively. The first pin 11 is inserted into the hole at the end of the magnet 00 5 axis sleeved with the spring, while the second cylindrical pin 12 is inserted into the other hole such that the connecting rod 6 inserted into the slot 3.6 is ,I rotatable around the second cylindrical pin 12.

oo 00 SAs shown in Figure 1, Figure 2, and Figure 5, the latch base 4 for positioning and supporting other parts is mounted on the panel 9 and provided with a side slot 4.1, a center hole 4.2, a side hole 4.3 and an opening 4.4. The latch 5 is inserted into the center hole 4.2 of the latch base 4 and is movable therein. The opening 4.4 at the side of the latch base 4 is communicated with the center hole 4.2 to form a space for receiving other parts. The actuation element 3 is installed in the opening 4.4 of the latch base 4. A side hole 4.3 is provided at each of the two sidewalls or only one sidewall of the opening 4.4.

When the side hole 4.3 is provided at each sidewall, the two side holes are coaxial. A side groove is further provided at the sidewall of the center hole 4.2 opposite to the opening 4.4.

As shown in Figure 4a and Figure 4b, the latch 5 includes a protrusion 5.1, a cylindrical protrusion 5.2, a latch tail 5.3 and a latch head 5.4. The latch 5 is installed in the center hole 4.2 of the latch base 4. The latch tail 5.3 is Ishaped and the latch tail 5.3 is installed in the recess 3.4 of the actuation part 3.

The latch head 5.4 can extend out from the center hole 4.2 of the latch base 4.

The protrusion 5.1 is provided at a side of the latch tail 5.3, and is located in the side groove 4.1 of the latch base 4 to limit the movement of the latch 5. The cylindrical protrusion 5.2 is at the bottom of the latch tail 5.3, and it is used for limiting the position of the actuation element 3 during rotation. In an alternative embodiment, the position limiting of the actuation element 3 during rotation is achieved by a cylindrical pin, that is, the cylindrical protrusion 5.2 is replaced by the pin to obtain the same function and result.

As shown in Figure 5, the lock assembly steps are as follow: the magnet axis 1 sleeved with the spring 2 is inserted in the solenoid 7, and one end of the spring 2 urges against the first cylindrical pin 11 of the magnet axis 1, while the other end urges against the end face of the solenoid 7.The latch base 4 is

O

Sfixed on the panel 9.One end of the integrated circuit board 8 is fixed on the latch base 4, and the other end of the integrated circuit board 8 is fixed on the bracket 00oo When power is on, a magnetic field is generated by the solenoid 7 to move the magnet axis 1 axially inside the solenoid 7. When the magnet axis 1 is 0 moved inwards with respect to the solenoid, the connecting rod 6 is moved by the magnet axis 1, and the actuation element 3 hinged to the rod 6 is subsequently moved. The actuation head of the actuation element 3 rotates around the third cylindrical pinl3 of the latch base 4 to push the latch downwards to extend out from the latch base 4 until the lock reach the locking position. At the locking state, the latch 5 can not be withdraw upon an external force since certain angles are formed among the actuation element 3, the cylindrical protrusion 5.2 of the latch 5, the connecting rod 6 and the magnet axis 1, and the actuation head 3.3 of actuation element 3 is interfered with the cylindrical protrusion 5.2 of the latch When power is off, the magnetic field of the solenoid 7 disappears, and the spring 2 pushes the magnet axis 1 outwards with respect to the solenoid 7.

Then, the connecting rod 6 moves the actuation element 3 such that the actuation element 3 rotates right about to withdraw the latch The above-mentioned state is a state that the lock is locked when the power is on. Alternatively, the lock may be locked when the power is off, which may be achieved by rotating the actuation element 3 with an angle of 1800, that is, the actuation element 3 is assembled in reverse. Therefore, the user may make his choice in accordance with particular requirements.

While the present invention is described in connection with what is presently considered to be the most practical and preferred embodiments, it should be appreciated that the invention is not limited to the disclosed embodiments, and is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention. Modifications and variations in the present invention may be made without departing from the novel aspects of the invention.
