[0017] Figure 2 It is structure schematic drawing of lock cover opening of the utility model embodiment;
[0018] Figure 3 It is structure schematic drawing of self -weight lock cylinder of the utility model embodiment;
[0019] Figure 4 It is cross section structure schematic drawing of the utility model embodiment. DETAILED DESCRIPTION
[0020] The embodiments of the utility model are further explained in connection with the drawings.
[0021] As Figures 1-4 The utility model discloses a self -weight cabinet door lock, including lock shell 1, the outside of lock shell 1 is equipped with lock cover 2, and the upper end of lock cover 2 is hinged to lock shell 1, and the inboard of lock cover 2 lower end is equipped with self -weight lock cylinder 4, and the lower end of lock shell 1 is equipped with the lock hole 9 that cooperates with self -weight lock cylinder 4, and the inboard of lock shell 1 is equipped with lock bolt 3, and lock shell 1 is equipped with handle 5, and handle 5 is connected with lock bolt 3 through connecting shaft 6, and one end of connecting shaft 6 is hinged handle 5 bottom, and the other end is fixed with lock bolt 3. When the cabinet door lock is in the locking state, the lower end of self -weight lock cylinder is limited in the lock hole 9 due to the weight of itself, at this moment, lock cover 2 can not open, and locking is stable;When needing to open, the self -weight lock cylinder is lifted and separated from the lock hole 9 by using magnetic key 101 or strong magnet outside lock cover 2, and lock cover 2 can be opened, and the handle is pulled down and rotated to make lock bolt 3 rotate and open the cabinet door, and the self -weight lock cylinder also does not loosen after lifting for many times, and opening is convenient, can effectively guarantee locking stability, avoids the occurrence security accident.
[0022] As Figures 3-4 shown, the gravity lock core includes a base 22, a lock core, and a magnetic sheet 21. The base 22 is fixed to the inner side of the lock cover, and the base 22 is provided with a through hole 31. The lock core includes a guide part 23, a limiting part 24, and a locking part 26. The guide part 23 is provided in the through hole 31. The guide part 23 is a cuboid, and the through hole 31 is a square hole matched with the guide part 23, so that the guide part 23 does not rotate and deviate when moving up and down. The limiting part 24 is provided at the lower end of the guide part 23 and has a width greater than the diameter of the through hole 31, so as to avoid the lock core from being separated from the through hole when moving up and to ensure stable locking. The locking part 26 is provided at the lower end of the limiting part 24 and cooperates with the lock hole 9. Since the lock cover 2 is opened by turning, preferably, a guide inclined surface 25 is provided at the lower end of the limiting part 24 away from the lock cover side. The thickness of the locking part 26 gradually decreases from the side close to the lock cover, so as to avoid the gravity lock core from colliding with and being stuck in the lock hole 9 when the lock cover 2 is turned. The magnetic sheet 21 is L-shaped. One end of the magnetic sheet 21 is fixed to the upper end of the lock core, and the other end is bent and extends to abut against the inner side wall of the lock cover. The bent part enlarges the area that can be attracted by the magnet, so as to be conveniently magnetically attracted by the magnetic key 101 or a strong magnet.
