Detailed Description

The utility model is further described below with reference to the accompanying drawings:

referring to fig. 1: the utility model provides a door lock is inhaled to nail-free magnetism in this embodiment 1, including the lock body 1 and the magnetism of fixed mounting on door body and door frame respectively inhale hasp box 2, be equipped with magnetism on the lock body 1 and inhale spring bolt 3 and spring bolt pull back mechanism 4, the magnetic attraction spring bolt 3 can magnetically attract to realize locking the door on the magnetism inhales hasp box 2 after closing the door, spring bolt pull back mechanism 4 can utilize lock core or handle drive magnetism to inhale spring bolt 3 and withdraw in the lock body 1, one side of lock body 1 and magnetism inhale hasp box 2 all is equipped with fixed plate 5, carries out fixed connection through screw 6 between the fixed plate 5 and the door body or door frame, and the both sides of fixed plate 5 are equipped with two draw-in grooves 7 respectively, be equipped with decoration panel 8 on the fixed plate 5, the inboard both sides of decoration panel 8 are equipped with two trip 9 respectively, and trip 9 and draw-in groove 7 correspond to dismantle the buckle and be connected. The decorative panel 8 is not provided with screw holes, so that screw heads cannot be exposed, the lock is more attractive after being installed, the decorative panel 8 and the fixing plate 5 are detachably buckled through the clamping hooks 9 and the clamping grooves 7, and the panels with different colors can be replaced conveniently and randomly.

As shown in fig. 2, in embodiment 2, on the basis of embodiment 1, the magnetic latching box 2 is composed of an electromagnet 14 and a permanent magnet 15, the permanent magnet 15 and the magnetic latching tongue 3 are attracted to each other in opposite poles, the electromagnet 14 and the magnetic latching tongue 3 are arranged in a homopolar repulsion mode, and the electromagnet 14 is electrically connected with a direct current power supply and an indoor control switch. When the indoor control switch is closed, the direct-current power supply supplies power to the electromagnet 14, and the electromagnet 14 generates repulsive force to the magnetic attraction lock tongue 3, wherein the repulsive force is larger than attractive force of the permanent magnet 15 to the magnetic attraction lock tongue 3. The door body is generally provided with a door closer, after the door is closed, the permanent magnet 15 and the magnetic spring bolt 3 can not be attracted, so that the normally open arrangement of the door body is realized, the trouble of frequently rotating the handle to open the door is avoided, and the service life of the door lock is prolonged.
