DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] like Figure 1-6 As shown, the utility model provides a magnetic door lock with an elastic handle, which is mainly used for locking a door. Its specific structure mainly consists of a door frame lock 1 and a door lock 2. The door frame lock 1 is mainly installed in a door frame for fixed use, while the door lock 2 is installed inside the door for use. When the door is locked, the door lock 2 is automatically fixedly connected to the door frame lock 1 through magnetic attraction. When the door is opened, the door lock 2 is separated from the door frame lock 1.

[0028] The door frame lock 1 is provided with a buckle box 101 for being assembled inside the door frame. The buckle box 101 is hollowed out in the middle and a first strong magnet 102 is provided at the rear end for sealing the hollowed out part after being clamped. An iron sheet 103 is also provided at the rear end of the buckle box 101 for being magnetically fixed to the first strong magnet 102. The door frame lock 1 is assembled on the door frame in an embedded installation manner. After the buckle box 101 is assembled, a first decorative cover 104 with first screws 105 inserted at both ends is also provided on the surface to be locked with the buckle box 101 and the door frame. A slot for placing the hollow piece of the buckle box 101 is added in the door frame, and the first strong magnet 102 and the iron sheet 103 are assembled at one end close to the bottom of the slot. When the first strong magnet 102 and the iron sheet 103 are fixed at the rear end of the buckle box 101, the buckle box 101 is provided with a slot 106 for inserting the first strong iron sheet 102 from the top, and the rear end of the buckle box is provided with a placement slot 107 for placing and fixing the iron sheet 103. The iron sheet 103 can fix the first strong magnet 102 and enhance its magnetic force.

[0029] The door lock 2 is provided with a handle-shaped lock shell 201, and the door lock 2 is also installed in the door in an embedded installation manner. After the lock shell 201 is assembled, a second decorative cover 210 with second screws 211 inserted at both ends is used to lock the lock shell 201.

[0030] The lock shell 201 is provided with a lock tongue 202 which is protruded and inserted into the hollow part of the buckle box 101, and a first transmission member 203 which is connected to the rear end of the lock tongue 202 and moves synchronously back and forth. The lock shell 201 is provided with an unlocking component 205 and a linked second transmission member 206. A synchronized third transmission member 207 is provided between the second transmission member 206 and the first transmission member 203. A plurality of transmission components are linked inside, which are mainly used to open the door when the door is locked. The transmission components are linked to each other to achieve the purpose of smoothly opening the door. It should be noted that the lock tongue 202 is made of non-magnetic aluminum alloy, and will not have any magnetic effect with the first strong magnet 102 and the second strong magnet 204.

[0031] The top of the unlocking component 205 is provided with a socket 213 exposed on the surface of the lock shell 201, and one side of the unlocking component 205 is provided with a first linkage part 214 that pushes the second transmission member 206 after clockwise rotation, and one side of the third transmission member 207 is provided with a second linkage part 215 that is protruding and connected to the front end of the second transmission member 206, and the other side of the third transmission member 207 is provided with a third linkage part 216 that is stuck inside the first transmission member 203. The situation in which the internal transmission components are linked to each other mainly depends on the situation in which the unlocking component 205 rotates, that is, the door is opened from the locked state, and the following is explained in detail:

[0032] In the first case, the door is completely separated from the door frame after being opened. In this case, the door is in a stationary state and there is no need to operate the unlocking assembly 205. There is no force for the linkage operation between the transmission components in the lock shell 201. In this case, the rear end of the lock tongue 202 protruding forward is pulled by the tension spring 209. Under the force of the contraction of the tension spring 209, the lock tongue 202 and the first transmission member 203 move backward together until the lock tongue 202 retracts into the lock shell 201. That is, the tension spring 7 can pull the lock tongue 202 back into the lock shell 201 when the door is open. When the door is open, the lock tongue 202 is not exposed, which is convenient for preventing the lock tongue 202 from colliding with pedestrians after the door is opened.

[0033] In the second case, the door moves from an open state toward the door frame to contact the locked door. Before the door contacts the door frame, the door is stationary and the lock tongue 202 does not protrude from the front end of the lock shell 201. When the door contacts the door frame, second strong magnets 204 that are magnetically fixed to the first strong magnet 102 are inserted at both ends of the lock tongue 202. As the door is closed on the door frame, the second strong magnet 204 on the lock tongue 202 and the first strong magnet 102 in the buckle box 101 have opposite polarities, and the two strong magnets are attracted to each other. The attractive magnetism causes the lock tongue 202 to slide in the hollow part of the buckle box 101, causing the lock tongue 202 to protrude, thereby achieving the effect of locking the door. It should be particularly noted that the attraction between the first strong magnet 102 and the second strong magnet 204 is greater than the pulling force of the tension spring 209 at the rear end of the lock tongue 202.

[0034] In the third case, the door is opened from the state of being locked in the door frame, that is, the unlocking operation, after the unlocking key is inserted into the jack 213, it drives the unlocking assembly 205 to rotate clockwise, and while the unlocking assembly 205 rotates, the first linkage part 214 pushes the second transmission member 206 forward, at this time, the compression spring 208 is synchronously squeezed and contracted, and the front end of the fifth linkage assembly 206 pushes the second linkage part 215 of the third transmission member 207 to make the third transmission member rotate clockwise in situ, at this time, the third linkage part 216 on the third transmission member 215 drives the first transmission member 203 to move backward in a linkage manner, and while the first transmission member 203 moves backward, the lock tongue 202 is pulled back to achieve the purpose of unlocking, when the unlocking assembly 205 completes the unlocking and there is no external force, the internal compression spring 208 uses its own elasticity to allow the second transmission member 206 to drive the unlocking assembly 205 to reset in a linkage manner to maintain the original state.

[0035] Compared with the traditional technology, the door lock provided by the present technical solution is provided with a plurality of mutually linked transmission parts in the handle-shaped lock shell 201. The transmission parts are mutually linked to achieve the unlocking and resetting states. After unlocking, the lock tongue 202 is not exposed due to the action of the tension spring 209 to prevent collision with pedestrians. Moreover, the door frame lock 1 and the door lock 2 are automatically locked by the attraction of two strong magnets. Moreover, after locking, the door has good stability, is more convenient to use, and has better flexibility.

[0036] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
