[0028] like Figures 1 to 8 As shown, the present invention provides a specific embodiment of a handle movable lock.

[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 connecting member 500 and a limiting dividing member 600. The limiting dividing member 600 and the transmission assembly 400 are both arranged in the base 100, the lock head connecting member 500 is arranged on the transmission assembly 400, the driving member 200 is respectively connected to the limiting dividing member 600 and the transmission assembly 400, and the movement of the driving member 200 can drive the transmission assembly 400 to move, and drive the lock head connecting member 500 to move.

[0030] A first limiting structure is provided between the limiting partition 600 and the base 100 , and 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 locked into 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 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 connector 500 to move; the transmission assembly 400 is arranged in the base 100 to transmit the power on the driving member 200 to the lock connector 500, and the lock connector 500 is used to connect the lock in the external door and window; the limit dividing member 600 is arranged in the base 100, and the limit 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 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 at different positions, and finally different locking states of the movable handle lock are realized.

[0034] In this embodiment, reference Figures 1 to 3 The handle movable lock includes three gears, i.e., three locking states. The limit dividing piece 600 includes two first engaging parts 610, and six second engaging parts 110 are arranged 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 piece 600 and the two first engaging parts 610 on the limit dividing piece 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 engaged in the first locking state position. One engaging portion 610 will move to two other different second engaging portions 110 for limiting, thereby fixing the external lock in the second locking 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 connecting member 500 to move, thereby driving the limiting dividing member 600 and the two first engaging portions 610 on the limiting dividing member 600 to continue to move, and when the lock connecting member 500 drives the external lock to move to the third locking state position, the two first engaging portions 610 will respectively move again to two different second engaging portions 110 for limiting in the next state, thereby fixing the external lock 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 rotate to the avoidance groove 601 to realize the positioning of the driving member 200.

[0037] Among them, a plurality of avoidance grooves 601 are arranged on the limit dividing member 600 to correspond to a plurality of locking state points. When entering different locking states, the telescopic block on the driving member 200 can be rotated to different avoidance grooves 601 to realize the positioning of the driving member 200 under 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 component 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, and there are 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 arranged between the limit dividing member and the base, and a second limit structure is arranged 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 arranging the limit dividing member to be able to follow the movement of the transmission assembly relative to the base, not only can the positioning of different locking states be achieved through the first limit structure, but 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, thereby effectively improving the accuracy and stability of the 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 arranged in the limit 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 arranged on the base 100, three of which are arranged at one end of one of the balls 610, and the other three slots 110 are 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 inserted into 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 limit dividing piece 600 and the two balls 610 on the limit dividing piece 600 Movement, when the lock connecting member 500 drives the external lock to move to the first locking state position, the two balls 610 will move to the other two different slots 110 respectively for limiting, so that the external lock is fixed in the second locking 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 connecting member 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 connecting member 500 drives the external lock to move to the third locking state position, the two balls 610 will move to the other two different slots 110 again respectively, so that the external lock is fixed in the third locking state position.

[0042] In one embodiment, reference Figure 2 An elastic member 620 is disposed inside 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 2The 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 from the limiting partition 600 and be inserted into 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 from the limiting partition 600 and is inserted into the card slot 110. When the user applies force to the driving member 200 to make the driving member When the lock 200 rotates, the driving member 200 will drive the transmission assembly 400 and the lock head connecting member 500 to move, thereby driving the limit partition 600 and the two balls 610 on the limit partition 600 to move. At this time, the two balls 610 will be separated from the slot 110, and the avoidance of the slot 110 disappears. The balls 610 will be squeezed by the stress of the base 100 and the elastic member 620, so that the elastic member 620 is compressed and contracted, so that the balls 610 are accommodated in the limit 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 and a second guide block 430. The first guide block 420 is movably arranged on the base 100 and is fixedly connected to the lock head connector 500. The second guide block 430 is fixed in the base 100. The gear 410 is arranged 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, so as to drive the gear 410 to roll on the second guide rail, so as to drive the first guide rail to move, and drive the lock core connector 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 arranged on a side surface of the first guide block 420 facing the second guide block 430, and a second rack is arranged on a side of the second guide block 430 facing the first guide block 420. The gear 410 is arranged between the first guide block 420 and the second guide block 430, and is respectively meshed 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 movement distance 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 disposed at two ends of the gear 410 in its moving direction.

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

[0050] In one embodiment, reference Figure 1 and Figure 3 A baffle 700 is disposed between the first guide block 420 and the limiting dividing member 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 the two 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, and 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 receiving groove 120 is mainly used to receive the driving member 200, and the second receiving groove 130 is used to receive the gear 410, the first guide block 420 and the second guide block 430. The first receiving groove 120 and the second receiving groove 130 are arranged side by side and the notches are arranged in reverse order to reduce the space occupied by the two. The connecting rod 300 passes through the first receiving groove 120 and the second receiving groove 130. One end of the connecting rod 300 is connected to the driving member 200 in the first receiving groove 120, and the other end of the connecting rod 300 is fixedly connected to the gear 410 in the second receiving 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 receiving groove 130, and driving the lock head connecting member 500 to move, and driving the external lock head to move to achieve different locking states; wherein, the driving member 200 can be moved and stored and hidden in the first receiving groove 120 to provide better aesthetics and higher safety.

[0054] In one embodiment, reference Figure 8 A sealing plate 131 is disposed 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 .

[0055] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. For those skilled in the art, the technical solutions described in the above embodiments can be modified, or some of the technical features therein can be replaced by equivalents; and all these modifications and replacements should fall within the protection scope of the claims attached to the present invention.
