The mutual engagement with the snap hole 442 allows the door panel to be arbitrarily opened relative to the door frame, so that the door panel can be kept in the closed state.

When the door is to be opened, please refer to FIG. 5, and the dial 22 can be rotated relative to the housing 10 by pulling or rotating the grip or the button connected to the dial 22, and then pushed by the dial 22 The member 24 moves the driving member 24 relative to the housing 10 in a direction different from the locking tongue 12, and then drives the locking tongue via the driving member 24. 12 moves in the direction in which the housing 10 is retracted, so that the locking portion 126 of the locking tongue 12 is completely retracted inside the housing 10, so that the user can open the door panel relative to the door frame, and the setting of the locking tongue spring 14 can be It is ensured that the locking tongue 12 is firmly positioned at the position retracted into the housing 10.

Since the two magnetic members 46 on the card 40 are respectively located on both sides of the latching hole 442, the thickness of the latching plate 40 of the present invention is not thickened by the provision of the magnetic member 46. Therefore, the locking hole arrangement on the existing door frame can be matched without further deepening the depth of the locking hole on the door frame. Therefore, the magnetic lock of the present invention can be combined with the thin door frame to improve the convenience of the present invention. Sexuality and practicality.

In addition, a locking mechanism 30 may be separately disposed in the body. Please refer to FIGS. 2, 3 and 6 . The locking mechanism 30 is disposed in the housing 10 and located between the locking tongue 12 and the driving mechanism 20 . Mainly comprising a locking member 34, the locking member 34 is movably disposed in the housing 10, and is movable by a lock, wherein the locking member 34 is movably disposed on the driving member 24. The one end of the locking member 34 is formed with an abutting end 342 which can abut against the locking tongue 12. The other end of the locking member 34 is opposite to the limiting piece 104 protruding from the housing 10 for the locking member. An elongated guiding hole 344 is disposed on the driving member 24, and a guiding post 243 slidably extending into the guiding hole 344 is formed on the driving member 24, whereby the user rotates the locking core with a key or the like. When the locking member 34 is moved to the position where the abutting end 324 abuts against the locking tongue 12, and the opposite end of the locking piece 34 is opposite to the limiting piece 104 of the housing 10, the locking tongue can be prevented. The 12 is arbitrarily pushed and retracted into the casing 10.

A clamping groove 245 is further disposed on the driving member 24, and a positioning groove 246 is formed in the locking groove 245 toward the end of the locking tongue 12, and the locking member 34 is formed on the locking member 34. The upper protruding portion is formed with a locking protrusion 345 which is slidable relative to the locking groove 245 and can be locked in the positioning groove 246, and a locking column 35 is disposed on the locking member 34, and the pushing rod 35 is fastened at one end. The other end of the housing 10 is connected to a spring 352, so that when the locking member 34 moves relative to the driving member 24, the locking protrusion 345 can be moved along the locking groove 245, to be locked. When the protrusion 345 is moved to the opposite side of the positioning groove 246, the spring 352 can be pushed to push the column 35 to push against the inner wall surface of the casing 10, so that the locking member 34 is deflected relative to the driving member 24, and the locking protrusion is made. The latch 345 is inserted into the positioning slot 246, and one end of the locking member 34 is opposite to the limiting piece 104, whereby the limiting piece 104 can be used to abut against the locking piece 34 to provide a stable limiting effect of the locking member 34. The lock member 34 is prevented from being arbitrarily pushed and moved, thereby providing a stable locking effect of the lock tongue 12, so that the magnetic lock can be stably held in the locked state.

At this time, if a person pulls the grip or turns the rotary button, the dial 22 can be rotated relative to the housing 10, but at this time, the dial 22 pushes against the driven block 244 to move relative to the driving member 24 and compresses the received spring 247. The driving member 24 is not moved relative to the housing 10, so that the locking tongue 12 can be held in the locked state of the protruding housing 10, and the grip or the rotary knob is idling.

When the lock core is reversely rotated by a key or the like, the lock member 34 can be reversely rotated relative to the driving member 24 to disengage the locking post 345 from the positioning groove 246, and the lock member 34 is moved. And away from the position of the locking tongue 12 and the end thereof opposite to the limiting piece 104, thereby releasing the locking state of the locking tongue 12, so that the user can rotate the locking block 22 to push the locking tongue 12 into the shell. Inside the body 10 to open the door panel.

Please also refer to FIG. 7 , which is another embodiment of the present invention. It can be seen that the locking tongue 12A can be directly retracted into the housing 10A by the dialing block 22A, and a dialing block 128 can be formed on the side of the connecting portion 122A of the locking tongue 12A, and the dialing block 22A can be arranged. Then, the protruding arm 23 is formed in a curved shape, so that when the user pulls the handle or rotates the rotary button, the arm 23 of the dial 22A can be pushed against the dialed block 128 to directly drive the protruding housing 10A. The locking tongue 12A is retracted inside the housing 10A, allowing the user to open the door panel, thereby providing a different structural configuration to accommodate different uses and design requirements.

Please refer to FIG. 8 , which is another embodiment of the present invention. As can be seen from the figure, only one magnetic member 13B can be disposed on the locking tongue 12B. The magnetic member 13B is disposed in the middle of the connecting portion 122B. At the position of the locking portion 126B, the door is closed so that the locking tongue 12B faces the locking hole 442B of the latching plate 40B, and the locking portion 126B of the locking tongue 12B is stuck by the magnetic force between the magnetic members 13B, 46B. When the magnetic member 13B on the locking tongue 12B is disposed on the connecting portion 122B, the magnetic member 13B is still located inside the body 10B at this time, so that it is not on the latching plate 40B. The internal magnetic field generated by the magnetic member 46B is pushed out, and the magnetic member 13B on the locking tongue 12B can exert a magnetic force with the two magnetic members 46B to adsorb the locking portion 126B of the locking tongue 12B toward the inside of the clamping plate 40B according to the direction of the magnetic field. And can achieve the effect of effective locking.
