Detailed ways

Referring to Figures 1 to 4, a cam-type intelligent magnetic lock body embodiment of the present invention will be further described in detail.

As can be seen from Figures 1 and 2, a cam-type intelligent magnetic lock body includes a lock shell 1, a magnetic upper lock tongue 2, a magnetic lower lock tongue 3 and a drive device 4, and the lock shell 1 is provided with a magnetic lock respectively. The upper bolt hole 11 and the lower bolt hole 12 through which the tongue 2 and the magnetic lower bolt 3 enter and exit, when the magnetic upper bolt 2 and the magnetic lower bolt 3 are under the action of the magnetic force, the upper bolt hole 11 and the lower bolt can be extended. The tongue hole 12 is locked, and when it needs to be unlocked, it can be unlocked by the driving device 4 .

As can be seen from FIG. 3, the driving device 4 includes an upper driving member 41, a lower driving member 42, a rotating shaft 43 and a cam assembly 44 that are rotatably arranged on the lock housing 1;

The cam assembly 44 includes a cam 441 rotatably disposed on the lock housing 1 and a motor 442 that drives the cam 441 to rotate. The output shaft of the motor 442 is connected with a worm 443, wherein the turbine 444 is fixedly connected to the cam 441, and the motor 442 is connected through the worm. 443 drives the turbine 444 to rotate, so as to drive the cam 441 above the turbine 444 to rotate;

The upper driving member 41 is arranged on the rotating shaft 43, and one end of the upper driving member 41 is in conflict with the cam 441. It can be seen from FIG. 41 is in conflict with the outer contour of the cam 441, and is placed between the anti-detachment cover 445 and the turbine 444 to prevent the cam 441 from disengaging the upper driving member 41 during the rotation process and improve the rotational stability; the other end of the upper driving member 41 is When the magnetic upper locking tongue 2 is matched, when the upper driving member 41 swings backward, it pushes the magnetic upper locking tongue 2 to move backward and retracts the upper locking tongue hole 11;
