Some embodiments of the present utility model are described in detail below with reference to the accompanying drawings. The following embodiments and features of the embodiments may be combined with each other without conflict.
As shown in fig. 1 to 8, according to a first aspect of the present utility model, there is provided a connection mechanism 100 for use in a display screen including a display screen module 200 and a display screen frame 300, the connection mechanism 100 including a first connection member 10 for connection with the display screen module 200 and a second connection member 20 for connection with the display screen frame 300. Wherein, a lock bar 21 is disposed on one of the first connector 10 and the second connector 20, and a lock hole 123 is disposed on the other of the first connector 10 and the second connector 20, so that the lock bar 21 can be inserted into the lock hole 123 and fixedly connected with the lock hole 123, for mounting the display module 200 on the display frame 30.
In this embodiment, the lock lever 21 has a locking groove 211, and a limiting component is installed in the locking hole 123, where the limiting component includes a locking ball 13 and a locking ball, and a movable seat 11 having a magnetic attraction function and a conical structure. Wherein, the movable seat 11 is provided with a movable slot 112 and a plugging hole 111, the locking ball 13 is movably installed in the movable slot 112 and can move along the direction of the plugging hole 111 under the drive of the side wall of the locking hole, and is used for being clamped in the locking slot 211, so that the locking rod 21 can be fixed in the locking hole 123 by the cooperation of the locking ball 13 and the locking slot 211, or can be unlocked by the separation of the locking ball 13 and the locking slot 211, i.e. the second connecting piece 20 is connected with the first connecting piece 10 by the cooperation of the locking ball 13 and the locking slot 211. In addition, the locking ball 13 can be separated from the locking groove 211 by the magnetic attraction function of the movable seat 11, thereby accomplishing the separation of the second link 20 from the first link 10.
By way of example, the movable seat 11 is driven to move by the magnetic attraction structure outside the connection mechanism 100 or the magnetic attraction structure inside the connection mechanism 100, and the movable seat 11 can control the locking ball 13 to move along the direction of the movable groove 112 towards or away from the plug hole 111 during the movement, so that the locking ball 13 can be clamped in the locking groove 211 or separated from the locking groove 211, thereby realizing the connection or separation of the second connection piece 20 and the first connection piece 10.
During the moving process of the movable seat 11, the locking ball 13 may contact or indirectly contact with the sidewall of the lock hole, so that the locking ball 13 moves toward or away from the plugging hole 111 under the contact force or the non-contact force of the sidewall of the lock hole. For example, the side wall of the lock hole is provided with a magnetic attraction function, the locking ball 13 is away from the plug hole 111 under the action of magnetic attraction, and when the movable seat 11 moves near one side of the first connecting piece 10, the locking ball 13 moves near the plug hole 111 under the action of magnetic attraction and is clamped in the locking groove 211. Or the locking ball 13 moves in a direction of the insertion hole 111 by an elastic force or an abutment force, and when the movable seat 11 moves away from the side of the first connector 10, the locking ball 13 moves away from the insertion hole 111.
