TECHNICAL FIELD
[0001] The present application belongs to the technical field of furniture hardware, and relates to a magnetic sliding door lock. BACKGROUND
[0002] As a common opening mode of cabinet furniture such as wardrobes, the sliding door has the advantages of saving space and being elegant and atmospheric, but most of the sliding doors of wardrobes are in a state of no lock or "lock useless", that is, either no lock or not used due to the inconvenience caused by the existence of the lock. The "lock" of the wardrobe has its value, such as preventing children from opening by mistake and good privacy, and there are ways to set a door lock on the wardrobe in the prior art, but the traditional door lock needs the user to make "unlocking" and "locking" actions. Therefore, in most cases, the user does not choose to use the door lock of the wardrobe due to the non-humanized and simple structure, resulting in the current situation of having a lock but not using it. SUMMARY
[0003] The purpose of the present application is to solve the above-mentioned problems existing in the prior art, and to provide a magnetic sliding door lock. The technical problem to be solved by the present application is how to improve the operation convenience.
[0004] The purpose of the present application can be achieved by the following technical scheme: a magnetic sliding door lock, the sliding door comprising an outer frame and a door body sliding in the outer frame, the door body comprising a door frame and a door panel, characterized in that the magnetic sliding door lock comprises two mounting pipes fixed in a vertical edge frame of the door frame, two lock columns corresponding to the mounting pipes respectively, two permanent magnets corresponding to the lock columns respectively, and a handle connected to the two permanent magnets simultaneously, the lock column is connected in the corresponding mounting pipe through the spline longitudinal sliding, the handle comprises a holding part extending out of the door frame, an upper connecting part located in the door frame, and a lower connecting part located in the door frame, the upper connecting part and the lower connecting part are rotatably connected to the two lock columns respectively, the upper surface of the upper connecting part and the lower surface of the lower connecting part are respectively provided with a guide groove, the permanent magnet fixedly connected to the lock column above the handle is provided with a positioning pin one having a spacing with the lock column, the permanent magnet fixedly connected to the lock column below the handle is provided with a positioning pin two having a spacing with the lock column, the two permanent magnets are in a repelling state, and the bottom surface of the guide groove is a curved surface with a concave middle part.
[0005] Further, the vertical edge frame of the door frame provided with the handle is provided with a mounting opening, and each of the holding part and the upper connecting part and the holding part and the lower connecting part has a contraction part, and the mounting opening and the contraction part on the two sides correspond to limit the rotation of the handle around the lock column.
[0006] Further, the positioning pin one and the positioning pin two rotatably connected to one end of the corresponding guide groove are rotatably connected with a ball reducing the frictional resistance.
[0007] Further, the top and bottom of the outer frame have guide rails which are adapted to the upper and lower horizontal frames of the door frame, and a plurality of positioning openings are arranged on the guide rails and adapted to the heads of the lock posts.
[0008] As another solution, the top and bottom of the outer frame have anti-skid layers which are adapted to the heads of the lock posts.
[0009] The present solution adopts a "stop-to-lock" door lock mode. Specifically, when the handle is pulled to provide a pushing force for moving the door frame, the handle swings slightly around the lock post. This swing is reflected in the relative displacement of the positioning pin one and the positioning pin two in the respective guide groove. Since the middle part of the guide groove is recessed, when the positioning pin one and the positioning pin two are both located in the middle part of the guide groove, the lock post above the handle is moved upward under the repulsive force between the permanent magnets, and is moved upward to the top of the lock post which extends above the door frame and abuts against the upper guide rail of the outer frame, thereby achieving the locking between the door frame and the outer frame. Similarly, the lock post below the handle is moved downward under the repulsive force between the permanent magnets, and is moved downward to the lock post which extends below the door frame and abuts against the lower guide rail of the outer frame, thereby achieving the locking between the door frame and the outer frame. When the handle is pulled to provide a pushing force for moving the door body, the positioning pin one and the positioning pin two can both move to either side of the guide groove, and the specific side to which they slide depends on the direction of the force applied by the handle. The external force overcomes the repulsive force between the permanent magnets, and moves the lock post above the handle downward and the lock post below the handle upward, thereby achieving the unlocking. That is, the door can be unlocked as long as the handle is pushed, otherwise it is in the locked state. The handle is located in the middle part of the door frame, and pulling the door body at other positions cannot cause the movement of the door body relative to the outer frame. Therefore, it not only achieves the stop-to-lock, but also does not need any operation in addition to the door pushing action, greatly optimizes the portability of the sliding door lock structure, and makes it more humanized. It overcomes the inconvenience caused to the user by the traditional door lock structure which needs to be separately opened and closed. The door lock structure is provided on the sliding door of a wardrobe, and has a quite simple structure and does not need energy consumption, thereby providing a new idea for the door lock structure of a light sliding door.

[0018] The following is a specific embodiment of the present application and further describes the technical solutions of the present application in conjunction with the drawings, but the present application is not limited to these embodiments.
[0019] As Figures 1-7 shown in the magnetic type sliding door lock, the sliding door includes an outer frame 1 and a door body sliding in the outer frame 1, the door body includes a door frame 21 and a door panel 22, the magnetic type sliding door lock includes two installation pipes fixed in a vertical edge frame of the door frame 21, two lock posts 3 corresponding to the installation pipes respectively, two permanent magnet blocks 4 corresponding to the lock posts 3 respectively, and a handle 5 connected with the two permanent magnet blocks 4 simultaneously, the lock post 3 is longitudinally slidingly connected in the corresponding installation pipe through a spline, the handle 5 includes a holding part 51 extending out of the door frame 21, an upper connecting part 52 located in the door frame 21, and a lower connecting part 53 located in the door frame 21, the upper connecting part 52 and the lower connecting part 53 are rotationally connected on the two lock posts 3 respectively, the lower surface of the upper connecting part 52 and the upper surface of the lower connecting part 53 are respectively provided with a guide groove 41, the permanent magnet block 4 fixedly provided on the lock post 3 above the handle 5 is provided with a positioning pin one 42 having a spacing with the lock post 3, the permanent magnet block 4 fixedly provided on the lock post 3 below the handle 5 is provided with a positioning pin two 43 having a spacing with the lock post 3, the two permanent magnet blocks 4 are in a repelling state, and the bottom surface of the guide groove 41 is a curved surface with a concave middle part.
[0020] The vertical edge frame of the door frame 21 on which the handle 5 is installed is provided with an installation opening, and each of the holding part 51 and the upper connecting part 52 and the holding part 51 and the lower connecting part 53 has a contraction part, the installation opening and the contraction part on both sides form a limit for the rotation of the handle 5 around the lock post 3, so that the swing amplitude of the handle 5 is equivalent to the width of the guide groove 41, and the guide groove 41 is an arc shape with the lock post 3 as the axis.
[0021] The positioning pin one 42 and the positioning pin two 43 are rotatably connected with the ball that reduces the frictional resistance at one end abutting against the corresponding guide groove 41, which is used to reduce the sliding resistance of the positioning pin one 42 and the positioning pin two 43 in the guide groove 41; as two ways to improve the locking effect, one is that the top and bottom of the outer frame 1 have guide rails that are adapted to the upper and lower horizontal frames of the door frame 21, and a plurality of positioning openings that are adapted to the head of the lock post 3 are arranged on the guide rails; the other is that the top and bottom of the outer frame 1 have anti-slip layers that are adapted to the head of the lock post 3.
[0022] The door lock structure adopts the "stop and lock" mode, specifically, when the handle 5 is pulled to provide a pushing force for the movement of the door frame 21, the handle 5 swings slightly around the lock post 3, and the swing is reflected in the relative displacement of the positioning pin one 42 and the positioning pin two 43 in the respective guide groove 41. When the positioning pin one 42 and the positioning pin two 43 are located in the middle of the guide groove 41, the lock post 3 above the handle 5 is moved upward under the repulsive force between the permanent magnets 4, and is moved to the top of the lock post 3 to extend above the door frame 21 and abut against the upper guide rail of the outer frame 1, thereby achieving the locking between the door frame 21 and the outer frame 1. Similarly, the lock post 3 below the handle 5 is moved downward under the repulsive force between the permanent magnets 4, and is moved to the bottom of the lock post 3 to extend below the door frame 21 and abut against the lower guide rail of the outer frame 1, thereby achieving the locking between the door frame 21 and the outer frame 1. When the handle 5 is pulled to provide a pushing force for the movement of the door body, the positioning pin one 42 and the positioning pin two 43 can move to both sides of the guide groove 41, and specifically slide to which side of the guide groove 41 according to the direction of the force applied to the handle 5. The external force overcomes the repulsive force between the permanent magnets 4, and the lock post 3 above the handle 5 is moved downward and the lock post 3 below the handle 5 is moved upward, thereby achieving unlocking. That is, as long as the handle 5 is pushed, the door can be unlocked, otherwise it is in a locked state. The handle 5 is located in the middle of the door frame 21, and pulling the door body at other positions cannot cause the movement of the door body relative to the outer frame 1. Therefore, it not only achieves stop and lock, but also does not need to add any operation other than the door pushing action, greatly optimizes the portability of the sliding door door lock structure, and makes it more humanized. It overcomes the inconvenience caused to users by the need for separate unlocking and locking actions in traditional door lock structures. The door lock structure is provided at the sliding door of a wardrobe and the like, and has a relatively simple structure and does not require energy consumption, thereby providing a new idea for the door lock structure of a light sliding door.
[0023] When it is used as a sliding door lock that can be controlled from the inside and the outside, the handle 5 needs two, which are symmetrically distributed on both sides of the lock post 3 and respectively extend out of both sides of the vertical frame of the door frame 21.
[0024] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art of the present application can make various modifications or supplements to the described specific embodiments or replace them with similar ways without departing from the spirit of the present application or exceeding the scope defined by the appended claims.
