Detailed Description

As shown in fig. 1 to 4, the connection structure of the present invention comprises a first connection member 1 and a second connection member 2 which are connected in a relatively rotatable and/or movable manner, a first locking member 3 and a second locking member 4 which are capable of cooperating with each other to restrict the relative rotation and/or movement of the first connection member 1 and the second connection member 2, a pulley 5, and a flexible cable 6, wherein the first locking member 3 is connected to the first connection member 1 and is movable relative to the first connection member 1, or the first locking member 3 is connected to the first connection member 1 and the second connection member 2 and is movable relative to the first connection member 1 and the second connection member 2; the second locking piece 4 is arranged on the second connecting piece 2; the pulley 5 is rotatably connected with the first locking piece 3 around the central axis thereof, and the flexible cable 6 passes around the pulley 5; when one end of the flexible cable 6 does not move, the other end of the flexible cable 6 is pulled, the pulley 5 rotates around the central axis thereof relative to the first locking part 3 and moves together with the first locking part 3, so that the first locking part 3 is disengaged from the second locking part 4, and the first connecting piece 1 and the second connecting piece 2 can rotate or/and move relatively.

The first locking part 3 is connected with the first connecting part 1 and can move relative to the first connecting part 1, that is, the first locking part 3 is only connected with the first connecting part 1, and the first locking part 3 can move relative to the first connecting part 1; the first locking member 3 is connected to the first connecting member 1 and the second connecting member 2 and can move relative to the first connecting member 1 and the second connecting member 2, that is, the first locking member 3 is connected to the first connecting member 1 and the second connecting member 2, and when moving, the first locking member 3 moves relative to the first connecting member 1 and also moves relative to the second connecting member 2.

The pulley 5 rotates about its central axis, that is, the pulley 5 rotates about its own central axis.

When the first locking piece 3 is matched with the second locking piece 4, the first connecting piece 1 and the second connecting piece 2 cannot rotate or/and move relatively, and the first connecting piece 1 and the second connecting piece are in a relatively locked state; pulling the flexible cable 6, pulling the first locking member 3 through the pulley 5, so that the first locking member 3 is disengaged from the second locking member 4, thereby unlocking the relative locking of the first connecting member 1 and the second connecting member 1, and enabling the first connecting member 1 and the second connecting member 2 to rotate or/and move relatively.

Because the connecting mechanism is arranged, after the flexible cable 6 is pulled, the pulley 5 not only can move relative to the first connecting piece 1 together with the first locking piece 3, but also the pulley 5 can rotate relative to the first locking piece 3 in a rotating mode around the central axis of the pulley 5, so that the pulley 5 forms a movable pulley structure relative to the first locking piece 3, and thus, the pulley 5 is driven to pull the first connecting piece 1 to move by pulling the other end of the flexible cable 6, and half of the force is saved compared with the conventional method that the first connecting piece 1 is directly pulled through the flexible cable 6, so that the unlocking operation of the first connecting piece 1 and the second connecting piece 2 of the connecting structure is labor-saving.

In this embodiment, a first elastic reset element 30 capable of driving the first locking element 3 to reset is preferably disposed between the first locking element 3 and the first connecting element 1 or between the first locking element 3 and the second connecting element 2. Under the action of the first elastic reset piece 30, the first locking piece 3 moves towards the second locking piece 4, and when the first locking piece 3 is aligned with the second locking piece 4, the first locking piece 3 automatically cooperates with the second locking piece 4.

The engaging member 32 may be formed integrally with the lock base 31, or may be a separate component connected to the lock base 31.

In one embodiment, one end of the flexible cable 6 is connected to the first connecting member 1, and when the other end of the flexible cable 6 is pulled, the first locking member 3 moves away from the second connecting member 2 and is disengaged from the second locking member 4. Specifically speaking, the fitting piece 32 of first locking piece 3 sets up to the locking pin, second locking piece 4 sets up to the locking groove that can supply the locking pin to insert, the export that locks groove 4 sets up in the one side towards first connecting piece 1, thereby first locking piece 3 toward keeping away from the direction removal of second connecting piece 2 can make fitting piece 32 break away from with the cooperation of second locking piece 4, first locking piece breaks away from the cooperation with the second locking piece promptly. In this embodiment, the other end of the flexible cable 6 passes around the pulley 5 and then extends away from the second connector 2 (shown in fig. 1), or the other end of the flexible cable 6 passes around the pulley 5 and then extends towards the second connector 2 via one or more guide wheels 51 (shown in fig. 2).

In another embodiment, one end of the flexible cable 6 is connected to the second connector 2, and when the other end of the flexible cable 5 is pulled, the first locking member 3 moves toward the second connector 2 and is disengaged from the second locking member 3. Specifically, the outlet of the locking groove 4 is arranged at the side away from the first connecting piece 1, so that the first locking piece 3 can be separated from the second locking piece 4 by moving towards the second connecting piece 2. In this embodiment, the other end of the flexible cable 6 passes around the pulley 5 and then extends away from the first connecting member 1 (shown in fig. 3), or alternatively, the other end of the flexible cable 6 passes around the pulley 5 and then extends via one or more guide wheels 51 and then extends toward the first connecting member 1 (shown in fig. 4).
