[0035] Refer to Figure 1, A ball lock according to an embodiment of the first aspect of the present invention includes a first ball lock body 100, a clutch member 200, a connecting rod 300, a clutch structure 400 and a linkage mechanism. The first ball lock body 100 includes a first fixing member 110 and a first glove cylinder 120. The first glove cylinder 120 is rotatably connected to the first fixing member 110. The clutch member 200 is rotatably arranged on the first fixing member 110. The connecting rod 300 passes through the clutch member 200. The connecting rod 300 can rotate synchronously with the clutch member 200, and the clutch member 200 can axially move along the length direction of the connecting rod 300. The clutch structure 400 is arranged between the first glove cylinder 120 and the clutch member 200. When the clutch structure 400 is engaged, the first glove cylinder 120 is in driving connection with the connecting rod 300, so that the first glove cylinder 120 drives the clutch member 200 to rotate and drives the connecting rod 300 to rotate synchronously. When the clutch structure 400 is disengaged, the connection between the first glove cylinder 120 and the clutch member 200 is disconnected. At this time, when the first glove cylinder 120 rotates, the clutch member 200 remains stationary relative to the first glove cylinder 120. The linkage mechanism is arranged on the first glove cylinder 120. The linkage mechanism can drive the clutch member 200 to move along the length direction of the connecting rod 300, so that the clutch structure 400 is engaged or disengaged. Specifically, the first ball lock body 100 is arranged inside the door. By rotating the first glove cylinder 120, the connecting rod 300 is driven to rotate. The rotation of the connecting rod 300 is linked with the lock tongue arranged on the door to lock and unlock the door. Through the clutch member 200, the clutch structure 400 and the linkage mechanism, the connection state between the first glove cylinder 120 and the connecting rod 300 can be switched, so that it has a separated and engaged state. In the implementation process, the process of switching to the separated state is as follows: by operating the linkage mechanism, the clutch member 200 is driven to move, so that the clutch member 200 moves along the length direction of the connecting rod 300. The clutch member 200 moves to a position where the clutch structure 400 between the first glove cylinder 120 and the clutch member 200 is disengaged. The clutch structure 400 is disconnected, so that the connection between the first glove cylinder 120 and the connecting rod 300 is disconnected. At this time, it is in the separated state. Rotating the first glove cylinder 120 cannot drive the connecting rod 300 to rotate, and the first glove cylinder 120 is in an idle rotation state. The process of switching to the engaged state is as follows: when in the separated state, the linkage mechanism is operated to drive the clutch member 200 to move. The clutch member 200 moves along the length direction of the connecting rod 300. The clutch member 200 moves to a position where the clutch structure 400 between the first glove cylinder 120 and the clutch member 200 is engaged. The clutch structure 400 is engaged, so that the first glove cylinder 120 and the connecting rod 300 are in driving connection. At this time, it is in the engaged state. Rotating the first glove cylinder 120 can drive the connecting rod 300 to rotate, and the locking or unlocking operation can be performed through the first glove cylinder 120. Therefore, after locking the door inside the door, the linkage mechanism can be operated to switch to the separated state. At this time, rotating the first glove cylinder 120 cannot unlock the door, which can prevent children from accidentally unlocking the door and improve the safety of the ball lock.

[0036] Refer to Figure 1 and Figure 2, in some embodiments of the present invention, the clutch structure 400 includes a connection groove 410 and a protrusion 420. The connection groove 410 is provided on the clutch member 200, and the protrusion 420 is provided on the first glove cylinder 120. The protrusion 420 can be inserted into or disengaged from the connection groove 410. The clutch member 200 is driven by a linkage mechanism to move along the length direction of the connecting rod 300. When the clutch member 200 is driven to move towards the first glove cylinder 120, the protrusion 420 is inserted into the connection groove 410. At this time, the clutch structure 400 is in a combined state. The combined state and the separated state of the clutch structure 400 can be quickly switched through the connection groove 410 and the protrusion 420.

[0037] It should be noted that the clutch structure 400 is not limited to the above embodiments, and there may be other embodiments. For example, the connection groove 410 may also be provided on the first glove cylinder 120, and the protrusion 420 may also be provided on the clutch member 200.

[0038] Refer to Figure 1 and Figure 3 , in some embodiments of the present invention, the linkage mechanism includes a linkage shaft 510 and a driving member 520. The driving member 520 is provided on the first glove cylinder 120. The linkage shaft 510 is in transmission connection with the driving member 520, and the linkage shaft 510 is in transmission connection with the clutch member 200. The driving member 520 drives the clutch member 200 to move along the length direction of the connecting rod 300 through the linkage shaft 510. Specifically, by operating the driving member 520 to drive the linkage shaft 510, the linkage shaft 510 drives the clutch member 200 to move, thereby switching the combined state and the separated state of the clutch structure 400. The driving member 520 can be manual or electric. It is convenient to operate through the driving member 520 and facilitate the state switching.

[0039] Refer to Figure 1 and Figure 3, in some embodiments of the present invention, the driving member 520 includes a knob 521 and a driving shaft 522. The knob 521 is rotatably connected to the first glove cylinder 120. One end of the driving shaft 522 is connected to the knob 521, and the other end is provided with a first transmission portion. One end of the linkage shaft 510 is provided with a second transmission portion. The first transmission portion and the second transmission portion are cooperatively driven so that the driving shaft 522 drives the linkage shaft 510 to move. The other end of the linkage shaft 510 abuts against the clutch member 200. A first elastic member 210 is provided between the clutch member 200 and the first fixing member 110. Specifically, by manually rotating the knob 521, the driving shaft 522 is driven to rotate. There is a first transmission portion and a second transmission portion between the driving shaft 522 and the linkage shaft 510. Through the cooperation between the first transmission portion and the second transmission portion, the rotational movement of the driving shaft 522 can drive the linkage shaft 510 to move. The linkage shaft 510 abuts against the clutch member 200, and the linkage shaft 510 moves towards the clutch member 200, compressing the first elastic member 210, driving the clutch member 200 to move until the clutch structure 400 is switched to the separated state. By rotating the driving shaft 522 to reset, the driving shaft 522 resets, the linkage shaft 510 resets under the elastic force of the first elastic member 210, and the clutch member 200 also resets under the elastic force of the first elastic member 210, and the clutch structure 400 returns to the combined state. The first elastic member 210 can increase the elastic force to reset the clutch member 200 and the linkage shaft 510 when the knob 521 resets. By manually operating the knob 521, the separation and combination of the clutch structure 400 can be switched, and the operation is simpler and more direct.

[0040] It should be noted that the driving member 520 is not limited to the above embodiments, and there may be other embodiments. For example, the driving member 520 may also include a button and the driving shaft 522. Pressing the button drives the driving shaft 522 to move, the driving shaft 522 drives the linkage shaft 510 to move, and the linkage shaft 510 drives the clutch member 200 to move, thereby switching the state of the clutch structure 400.

[0041] Referring to Figure 3 , in some embodiments of the present invention, the first transmission portion is provided with a wedge-shaped convex portion 523, and the second transmission portion is provided with a concave portion 511 that cooperates with the convex portion 523. When the convex portion 523 and the concave portion 511 cooperate, the clutch structure 400 is in the combined state. When the convex portion 523 rotates, the protruding portion of the convex portion 523 contacts the protruding portion of the concave portion 511 to push the concave portion 511 to move, and then push the linkage shaft 510 to move. Through the convex edge and the concave portion 511, the rotation of the driving shaft 522 can be converted into the movement of the linkage shaft 510.

[0042] In some embodiments of the present invention, a limiting block 512 is provided on the side wall of the linkage shaft 510, and a limiting groove 121 that cooperates with the limiting block 512 is provided in the first glove cylinder 120 along the axial direction of the linkage shaft 510. The cooperation between the limiting block 512 and the limiting groove 121 prevents the linkage shaft 510 from rotating. When the convex edge rotates, the concave portion 511 can only translate, which can further improve the transmission efficiency of the first transmission part and the second transmission part.

[0043] Referring to Figure 4 and Figure 5 , in some embodiments of the present invention, the ball lock further includes a second ball lock body 600. The second ball lock body 600 includes a second fixing member 610 and a second glove cylinder 620. The second glove cylinder 620 is rotatably connected to the second fixing member 610. A lock core 630 is provided in the second glove cylinder 620. The lock core 630 is connected to the connecting rod 300. A clamping assembly 640 is provided on the second glove cylinder 620. The lock core 630 is clamped to the second glove cylinder 620 through the clamping assembly 640. The lock core 630 can be directly clamped onto the clamping assembly 640. Specifically, the lock core 630 is not connected to the ball lock before the entire ball lock is installed. The lock core 630 can be installed by the user himself / herself, and only needs to be directly clamped to the ball lock, which is convenient for the user to modify the lock core 630.

[0044] Referring to Figure 4 and Figure 5 , in some embodiments of the present invention, a first clamping portion 641 is provided on the clamping assembly 640, and a guiding inclined surface 642 is provided on the first clamping portion 641. The guiding inclined surface 642 inclines towards the first ball lock body 100 in the direction of the lock core 630. A second clamping portion 631 is provided on the lock core 630. The first clamping portion 641 and the second clamping portion 631 are clamped and matched. When the lock core 630 is clamped, it first contacts the guiding inclined surface 642. Since the inclined direction of the guiding inclined surface 642 inclines towards the installation direction of the lock core 630, it can guide the lock core 630 during installation and reduce the installation resistance.

[0045] Referring to Figure 6 , in some embodiments of the present invention, the ball lock further includes a second elastic member 700. The second elastic member 700 is disposed on the second fixing member 610 and abuts against the side surface of the connecting rod 300. During implementation, the second elastic member 700 can be a spring wire. The cross-section of the connecting rod 300 is square. By driving the connecting rod 300 to rotate, the lock tongue on the linkage door is unlocked and locked. After rotation, the connecting rod 300 often cannot reach the correct rotation position. By providing a spring wire on the side surface of the connecting rod 300, an elastic force can be applied to the side surface of the connecting rod 300. Since the straight edge on the side surface of the connecting rod 300 is under the action of the elastic force and is in the correct position, it is convenient for the connecting rod 300 to reset.

[0046] It should be noted that the setting manner of the second elastic member 700 is not limited to the above embodiments, and there are other embodiments. For example, the second elastic member 700 can also be arranged on the first fixing member 110.

[0047] Referring Figure 6 , in some embodiments of the present invention, the ball lock further includes a third elastic member 800. The third elastic member 800 is disposed opposite to the second elastic member 700, and the third elastic member 800 abuts against the side surface of the connecting rod 300. The third elastic member 800 can be a spring wire. By providing the third elastic member 800, an elastic force can be further provided to the side surface of the connecting rod 300, making it easier for the connecting rod 300 to reset.
