[0029] A handle movable lock, reference Figure 1 The handle movable lock includes a base 100, a driving member 200, a transmission assembly 400, a lock head connector 500 and a limiting partition 600. The limiting partition 600 and the transmission assembly 400 are both arranged in the base 100, the lock head connector 500 is arranged on the transmission assembly 400, and the driving member 200 is respectively connected to the limiting partition 600 and the transmission assembly 400. The movement of the driving member 200 can drive the transmission assembly 400 to move, and drive the lock head connector 500 to move.

[0030] A first limiting structure is provided between the limiting partition 600 and the base 100 . The movement of the transmission assembly 400 can drive the limiting partition 600 to move relative to the base 100 and be limited by the first limiting structure.

[0031] Specifically, refer to Figures 1 to 3 The first limiting structure includes a first locking portion 610 arranged on the limiting partition 600, and also includes a second locking portion 110 arranged on the base 100. The movement of the transmission assembly 400 can drive the limiting partition 600 to move, so that the first locking portion 610 is engaged with the second locking portion 110, thereby realizing the limiting of different locking states.

[0032] refer to Figure 1 The base 100 is used to be fixed to the external door and window; the driving member 200 is used to drive the transmission assembly 400 and the lock head connector 500 to move. The user can apply force to the driving member 200 to make the driving member 200 rotate and drive the transmission assembly 400 and the lock head connector 500 to move; the transmission assembly 400 is arranged in the base 100 for transmitting the power on the driving member 200 to the lock head connector 500, and the lock head connector 500 is used to connect the lock head in the external door and window; the limiting dividing member 600 is arranged in the base 100, and the limiting dividing member 600 moves with the movement of the transmission assembly 400. It is mainly used to position the handle movable lock in different states, so that the external lock head is fixed in a specific position to achieve different locking states.

[0033] Further, refer to Figures 1 to 3 At least one first engaging portion 610 is provided on the limiting dividing member 600, and at least one second engaging portion 110 is provided on the base 100. When the limiting dividing member 600 moves along with the transmission assembly 400, the first engaging portion 610 can move relative to the base 100 and be engaged in different second engaging portions 110 on the base 100, so that the external lock head is fixed in different positions, and finally different locking states of the movable handle lock are achieved.

[0034] In this embodiment, reference Figures 1 to 3 , the handle movable lock includes three gears, i.e., three locking states, the limit dividing member 600 includes two first engaging parts 610, and six second engaging parts 110 are provided on the base 100 to realize the limit of three different locking states; when the handle movable lock is in the first locking state, the two first engaging parts 610 are respectively engaged in two different second engaging parts 110; when the user applies force to the driving member 200 to make the driving member 200 rotate, the driving member 200 will drive the transmission assembly 400 and the lock head connecting member 500 to move, thereby driving the limit dividing member 600 and the two first engaging parts 610 on the limit dividing member 600 to move, and when the lock head connecting member 500 drives the external lock head to move to the first locking state position, the two second engaging parts 110 are respectively engaged in the locking state. When the lock head connector 500 drives the external lock head to move to the third locking state position, the two first engaging portions 610 will move again to the two different second engaging portions 110 for limiting in the next state, thereby fixing the external lock head in the third locking state position.

[0035] In one embodiment, a second limiting structure is provided between the limiting partition 600 and the driving member 200 , and the driving member can move relative to the limiting partition 600 and be limited by the second limiting structure.

[0036] Specifically, refer to Figure 1 、 Figure 4 and Figure 5 A second limiting structure is also provided between the limiting dividing member 600 and the driving member 200. The second limiting structure includes a telescopic block 201 provided on the driving member 200 and a plurality of avoidance grooves 601 provided on the limiting dividing member 600. When the driving member 200 moves, it can drive the transmission assembly 400 to move. The movement of the transmission assembly 400 can drive the limiting dividing member 600 to move together, so that the limiting dividing member 600 can generate synchronous displacement with the driving member 200. When the driving member 200 rotates relative to the limiting dividing member 600, the telescopic block 201 can be rotated into the avoidance groove 601 to realize the positioning of the driving member 200.

[0037] Among them, a plurality of avoidance grooves 601 are provided on the limiting dividing part 600 to correspond to a plurality of locking state points. When entering different locking states, the telescopic block on the driving part 200 can be rotated to different avoidance grooves 601 to realize the positioning of the driving part 200 in different locking states.

[0038] The existing handle-movable lock has a limiting structure fixed on the base and cannot follow the movement of the transmission assembly and the movable handle. During use, when entering a certain locking state point, it is difficult to follow and limit the movable handle. The handle is easy to move, making the positioning of the lock not accurate and stable, posing certain safety hazards.

[0039] In this embodiment, a handle-movable lock is designed, which includes a base, a driving member, a transmission assembly, a lock head connecting member and a limit dividing member. A first limit structure is provided between the limit dividing member and the base, and a second limit structure is provided between the limit dividing member and the driving member. The movement of the driving member drives the transmission assembly to move, so as to drive the limit dividing member to move relative to the base and be positioned by the first limit structure. The driving member can move relative to the limit dividing member and be positioned by the second limit structure; by setting the limit dividing member to be able to follow the transmission assembly to move relative to the base, not only can positioning in different locking states be achieved through the first limit structure; it can also make the limit dividing member and the driving member produce synchronous displacement, and the driving member is positioned by the second limit structure, effectively improving the accuracy and stability of positioning.

[0040] In one embodiment, reference Figure 2 The first engaging portion 610 is a ball 610 , and the second engaging portion 110 is a slot 110 . The movement of the limiting partition 600 can drive the ball 610 to move so as to be inserted into the slot 110 .

[0041] Specifically, refer to Figure 2, two balls 610 are provided in the limiting dividing piece 600, which are respectively arranged at the two ends of the moving direction of the connecting rod 300, and six slots 110 are correspondingly provided on the base 100, three of which are correspondingly arranged at one end of one of the balls 610, and the other three slots 110 are correspondingly arranged at one end of another ball 610, so as to realize the limit of three different locking states; when the handle movable lock is in the first locking state, the two balls 610 are respectively stuck in two different slots 110; when the user applies force to the driving member 200 to make the driving member 200 rotate, the driving member 200 will drive the transmission assembly 400 and the lock head connecting member 500 to move, thereby driving the limiting dividing piece 600 and the two balls 610 on the limiting dividing piece 600 When the lock connector 500 drives the external lock to move to the third locked state position, the two balls 610 will move to two different slots 110 again to limit the position, so that the external lock is fixed in the second locked state position; when the user applies force to the driving member 200 again to make the driving member 200 rotate again, the driving member 200 will continue to drive the transmission assembly 400 and the lock connector 500 to move, thereby driving the limiting partition 600 and the two balls 610 on the limiting partition 600 to continue to move, and when the lock connector 500 drives the external lock to move to the third locked state position, the two balls 610 will move to two different slots 110 again, so that the external lock is fixed in the third locked state position.

[0042] In one embodiment, reference Figure 2 An elastic member 620 is provided in the limiting partition 600 , and the ball 610 is connected to one end of the elastic member 620 and is partially exposed outside the limiting partition 600 .

[0043] Specifically, refer to Figure 2, the elastic member 620 is mainly used to cooperate with the ball 610 so that the ball 610 can move relative to the limiting partition 600, so that the ball 610 can be accommodated in the limiting partition 600, and can also protrude outside the limiting partition 600 and be stuck in the card slot 110; when the handle movable lock is in one of the locking states, the positions of the two balls 610 will correspond to the positions of two of the card slots 110 respectively. Due to the avoidance of the card slot 110, the elastic force of the elastic member 620 can be released, so that the ball 610 is subjected to the elastic force and protrudes outside the limiting partition 600 and is stuck in the card slot 110. When the user applies force to the driving member 200 to make the driving member When 200 rotates, the driving member 200 will drive the transmission assembly 400 and the lock head connecting member 500 to move, thereby driving the limiting partition 600 and the two balls 610 on the limiting partition 600 to move. At this time, the two balls 610 will disengage from the slot 110, and the avoidance of the slot 110 disappears. The balls 610 will be subjected to the stress of the base 100 and squeeze the elastic member 620, so that the elastic member 620 is compressed and contracted, so that the balls 610 are accommodated in the limiting partition 600. When the handle movable lock enters the next locking state, the two balls 610 will be stuck in two different slots 110 again, and the elastic force of the elastic member 620 will be released again.

[0044] In one embodiment, reference Figure 6 The transmission assembly 400 includes a gear 410, a first guide block 420, a second guide block 430 and a connecting rod 300. The first guide block 420 is movably set on the base 100 and is fixedly connected to the lock connector 500. The second guide block 430 is fixed in the base 100. The gear 410 is set between the first guide block 420 and the second guide block 430 and is fixedly connected to the connecting rod 300; the movement of the driving member 200 can drive the connecting rod 300 to rotate, thereby driving the gear 410 to roll on the second guide block 430, thereby driving the first guide block 420 to move, and driving the lock connector 500 to move.

[0045] Specifically, refer to Figure 6 The first guide block 420 is movably connected to the base 100, and the second guide block 430 is fixedly connected to the base 100. The first guide block 420 and the second guide block 430 are respectively arranged on opposite sides of the base 100. A first rack is provided on the side surface of the first guide block 420 facing the second guide block 430, and a second rack is provided on the side of the second guide block 430 facing the first guide block 420. The gear 410 is provided between the first guide block 420 and the second guide block 430, and is respectively engaged with the first rack and the second rack.

[0046] Since the second guide block 430 is fixedly connected to the base 100 and the first guide block 420 is movably connected to the base 100, the gear 410 can move along the second rack when rolling, and drive the first guide block 420 to move together, so that the first guide block 420 moves relative to the base 100, and the longest stroke of the movement is the sum of the length of the first rack and the length of the second rack.

[0047] In this embodiment, by designing a movable first guide block 420 and a fixed second guide block 430, the moving stroke of the first guide block 420 is the sum of the length of the first rack and the length of the second rack, that is, the moving stroke of the lock cylinder is the sum of the length of the first rack and the length of the second rack. On the basis of not increasing the diameter of the gear 410 to ensure miniaturization, the moving stroke of the second guide block 430 is effectively increased. This solution not only meets the installation size requirements, but also meets the stroke requirements for complete locking.

[0048] In one embodiment, reference Figure 1 and Figure 2 The limiting dividing member 600 includes a first sliding block 630 and a second sliding block 640 , and the first sliding block 630 and the second sliding block 640 are respectively arranged at both ends of the gear 410 in its moving direction.

[0049] Specifically, refer to Figure 1 and Figure 2 A first engaging portion 610 is provided on each of the first sliding block 630 and the second sliding block 640, and three second engaging portions 110 are provided on the base 100 corresponding to the positions of the first sliding block 630 and the second sliding block 640, respectively, to realize the limiting of three different locking states.

[0050] In one embodiment, reference Figure 1 and Figure 3 A baffle 700 is provided between the first guide block 420 and the limiting partition 600 .

[0051] Specifically, refer to Figure 1 and Figure 3 The baffle 700 is used to separate the first guide block 420 and the limiting partition 600. The rotation of the gear 410 can drive the first guide block 420 and the limiting partition 600 to move along both sides of the baffle 700 respectively. By setting the baffle 700, the mutual influence between the first guide block 420 and the limiting partition 600 during the movement can be effectively eliminated.

[0052] In one embodiment, reference Figure 1 and Figure 7The base 100 is provided with a first receiving groove 120 for receiving the driving member 200 and a second receiving groove 130 for receiving the transmission assembly 400. The first receiving groove 120 and the second receiving groove 130 are arranged in opposite directions.

[0053] Specifically, refer to Figure 1 and Figure 7 The first accommodating groove 120 is mainly used to accommodate the driving member 200, and the second accommodating groove 130 is used to accommodate the gear 410, the first guide block 420 and the second guide block 430. The first accommodating groove 120 and the second accommodating groove 130 are arranged side by side and the notches are arranged in opposite directions to reduce the space occupied by the two. The connecting rod 300 passes through the first accommodating groove 120 and the second accommodating groove 130. One end of the connecting rod 300 is connected to the driving member 200 in the first accommodating groove 120, and the other end of the connecting rod 300 is fixedly connected to the gear 410 in the second accommodating groove 130. Pulling the driving member 200 can drive the connecting rod 300 to move, thereby driving the gear 410 to move, thereby driving the first guide block 420 to move along the notch of the second accommodating groove 130, and driving the lock connector 500 to move, and driving the external lock to move to achieve different locking states; wherein, the driving member 200 can be moved and stored and hidden in the first accommodating groove 120 to provide better aesthetics and higher safety.

[0054] In one embodiment, reference Figure 8 A sealing plate 131 is provided on the side of the second receiving groove 130 ; the sealing plate 131 is used to protect and fix the first guide block 420 , the second guide block 430 and the gear 410 .
