[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0034] See also Figures 1 to 3 The utility model discloses a linkage door system, comprising: a linkage mechanism, a door lock assembly 2 and a plurality of door leaves 1. Specifically, in the present embodiment, the number of the door leaves 1 is three; the linkage mechanism is arranged between two adjacent door leaves 1, and the linkage mechanism is used to drive the plurality of door leaves 1 to slide between an extended position and a stored position; the door lock assembly 2 comprises a lock box 21, a lock shell 22 and a lock tongue 23, and the lock tongue 23 is arranged on the lock shell 22; wherein, the door lock assembly 2 is arranged between two adjacent door leaves 1, the lock box 21 is arranged on one of the door leaves 1, and the lock shell 22 is arranged on the other door leaf 1, and when the plurality of door leaves 1 are in the extended position, the lock tongue 23 can be connected to the lock box 21 to limit the relative movement of the two adjacent door leaves 1 in the sliding direction, thereby achieving the purpose of locking the plurality of door leaves 1 in the extended position.

[0035] Specifically, a door lock assembly 2 is disposed between every two adjacent door leaves 1 .

[0036] Specifically, the sliding directions of the multiple door panels 1 can refer to Figure 2 e1 direction.

[0037] Specifically, when the plurality of door leaves 1 are in the extended position, the linkage door system is in the closed state, and when the plurality of door leaves 1 are in the stored position, the linkage door system is in the open state.

[0038] In the linkage door system provided by the present embodiment, the lock tongue 23 can be connected to the lock box 21 to limit the relative movement of two adjacent door leaves 1 in the sliding direction, so that multiple door leaves 1 can be locked in the expanded position, and the door can be locked without opening a hole in the door frame set in the door opening. Moreover, when the multiple door leaves 1 are in the storage position or have not moved to the expanded position, the lock tongue 23 will not be exposed from the frame of the door leaf 1 relatively close to the door frame, and the lock box 21 and the lock tongue 23 are not easy to fall into the line of sight of people. In this way, on the one hand, the linkage door system can be made more beautiful as a whole, and on the other hand, the danger of use caused by the collision of the lock tongue 23 with people or objects can be avoided. On the other hand, when the multiple door leaves 1 are in the expanded position, the door lock assembly 2 can fix the relative position of the two adjacent door leaves 1 in the sliding direction, and the door frame and the door leaf 1 relatively close to the door frame are not easy to loosen, and the overall sealing of the multiple door leaves 1 in the expanded position is better.

[0039] It should be noted that, in some other embodiments, the number of door leaves 1 can also be set to 2 or 4 or 5, etc., which can be selected according to actual needs and is not limited here.

[0040] like Figure 1 , Figure 2 and Figure 3 As shown, specifically, in this embodiment, the door leaf 1 has a vertical frame 11. When the multiple door leaves 1 are in the expanded position, in two adjacent door leaves 1, the vertical frame 11 of one door leaf 1 and the vertical frame 11 of the other door leaf 1 are opposite to each other. Preferably, the lock box 21 is arranged on the vertical frame 11 of one door leaf 1, and the lock shell 22 is arranged on the vertical frame 11 of the other door leaf 1. In this way, on the one hand, sufficient installation space can be provided for the installation of the door lock assembly 2, so that the door lock assembly 2 can be installed between the two adjacent door leaves 1. On the other hand, the vertical frame 11 of the door leaf 1 can be used to cover the door lock assembly 2 to further improve the overall aesthetics of the linkage door system.

[0041] More preferably, in this embodiment, in order to better hide the lock housing 22 , the lock housing 22 is installed in the inner cavity of the vertical frame 11 . Specifically, part of the lock housing 22 is located in the inner cavity of the vertical frame 11 .

[0042] It should be noted that, in some other embodiments, the lock housing 22 may also be completely located in the inner cavity of the vertical frame 11 , which can be selected according to actual needs.

[0043] It should be noted that, in some other embodiments, the door lock assembly 2 can also be arranged between the horizontal frames of two adjacent door leaves 1, and it can be arranged according to actual conditions, and no sole limitation is made here.

[0044] like Figure 4 , Figure 7 and Figure 8Preferably, in this embodiment, the lock box 21 is provided with a lock slot 211, and the lock tongue 23 can move between an extended position and a retracted position relative to the lock shell 22. When the lock tongue 23 is in the extended position, the lock tongue 23 can be snapped into the lock slot 211; when the lock tongue 23 is in the retracted position, the lock tongue 23 and the lock slot 211 are separated, and the multiple door leaves 1 can move along the sliding direction; specifically, when the multiple door leaves 1 are in the expanded position, the lock tongue 23 can be extended from the retracted position to the extended position, and the lock tongue 23 is snapped into the lock slot 211 to limit the relative movement of the two adjacent door leaves 1 in the sliding direction; in this way, the structure of the lock box 21 and the lock tongue 23 is relatively simple, the occupied space is relatively small, and the cooperation between the two is easier to achieve, and the manufacturing cost is relatively low.

[0045] It should be noted that, in some other embodiments, the lock tongue 23 and the lock box 21 can also be but not limited to electromagnetic cooperation. Specifically, when the multiple door leaves 1 are in the expanded position, the door lock assembly 2 can be energized to make one of the lock tongue 23 and the lock box 21 generate magnetism, and the lock tongue 23 and the lock box 21 can be magnetically fixed to limit the relative movement of two adjacent door leaves 1 in the sliding direction; when the multiple door leaves 1 need to be moved to the storage position, the door lock assembly 2 can be powered off to release the magnetic fixation between the lock tongue 23 and the lock box 21, and the multiple door leaves 1 can slide along the sliding direction.

[0046] Specifically, in this embodiment, the telescopic direction of the lock tongue 23 is perpendicular to the sliding direction of the plurality of door leaves 1 on the horizontal plane. Figure 2 e2 direction.

[0047] It is understandable that when the plurality of door leaves 1 are in the storage position or have not moved to the extended position, if the lock tongue 23 moves from the retracted position to the extended position, the lock tongue 23 is likely to collide with the door leaf 1, thereby affecting the normal sliding of the door leaf 1, or making it impossible for the lock tongue 23 to be engaged in the lock slot 211 of the lock box 21;

[0048] like Figures 4 to 8As shown, in order to solve the above-mentioned problem, further, in the present embodiment, the door lock assembly 2 also includes a limit member 25, which is arranged on the lock housing 22, and the limit member 25 can be switched between a first state and a second state; when the limit member 25 is in the first state, the limit member 25 is used to limit the movement of the lock tongue 23 to prevent the lock tongue 23 from moving from the retracted position to the extended position; when the limit member 25 is in the second state, the limit member 25 releases the movement restriction on the lock tongue 23 to allow the lock tongue 23 to move from the retracted position to the extended position. In this way, when multiple door leaves 1 are in the stored position or have not moved to the expanded position, the limit member 25 can be switched to the first state, thereby blocking the lock tongue 23 from moving from the retracted position to the extended position, thereby avoiding the problem of the lock tongue 23 colliding with the door leaf 1 and avoiding the problem that the lock tongue 23 cannot be engaged in the lock groove 211 of the lock box 21; when multiple door leaves 1 are in the expanded position, the limit member 25 can be switched to the second state, thereby allowing the lock tongue 23 to move from the retracted position to the extended position to be engaged in the lock groove 211, so as to limit the relative movement of the two adjacent door leaves 1 in the sliding direction and achieve the purpose of locking the door.

[0049] like Figures 4 to 8 As shown, preferably, in this embodiment, the lock box 21 protrudes with a push block 212, and the limiting member 25 is slidably connected to the lock housing 22; when the limiting member 25 is in the first state, the limiting member 25 is located in the moving path of the lock tongue 23 to block the lock tongue 23 from moving from the retracted position to the extended position; when the limiting member 25 is in the second state, the limiting member 25 is located outside the moving path of the lock tongue 23 to allow the lock tongue 23 to move from the retracted position to the extended position to be engaged in the lock slot 211;

[0050] It can be understood that the lock box 21 moves with a door leaf 1 to which it is connected, the lock shell 22 moves with another door leaf 1 to which it is connected, and the limit member 25 moves with the lock shell 22 to which it is connected; when multiple door leaves 1 slide relatively, the lock box 21 and the lock shell 22 will also move relatively, that is, the push block 212 and the limit member 25 will move relatively; in this way, when multiple door leaves 1 move to the expanded position, the push block 212 pushes the limit member 25 from the first state to the second state, thereby allowing the lock tongue 23 to move from the retracted position to the extended position to be engaged in the lock groove 211; when multiple door leaves 1 are in the storage position or have not moved to the expanded position, the push block 212 and the limit member 25 are separated, and at this time the limit member 25 can move from the second state to the first state, thereby blocking the lock tongue 23 from moving from the retracted position to the extended position.

[0051] Preferably, in this embodiment, the lock tongue 23 is provided with a notch 231, and the limiting member 25 is provided with a cantilever 253; when the limiting member 25 is in the first state, the cantilever 253 is located in the notch 231 to prevent the lock tongue 23 from moving from the retracted position to the extended position; when the limiting member 25 is in the second state, the cantilever 253 is located outside the notch 231 to allow the lock tongue 23 to move from the retracted position to the extended position to be engaged in the lock groove 211; in this way, the lock tongue 23 and the limiting member 25 are both more compact and the cooperation is more accurate and practical.

[0052] It should be noted that, in some other embodiments, the limit member 25 and the lock tongue 23 may also be but are not limited to electromagnetic cooperation. Specifically, the limit member 25 is an electromagnet; when the limit member 25 is in the first state, the limit member 25 is energized to generate magnetic force and is magnetically fixed to the lock tongue 23 to prevent the lock tongue 23 from moving from the retracted position to the extended position; when the limit member 25 is in the second state, the limit member 25 is de-energized and the magnetic force of the limit member 25 disappears, thereby allowing the lock tongue 23 to move from the retracted position to the extended position to be snapped into the lock slot 211.

[0053] like Figures 4 to 8 As shown, preferably, in this embodiment, the door lock assembly 2 also includes a first elastic member 26. When the push block 212 and the limiting member 25 are separated, the first elastic member 26 is configured to elastically reset the limiting member 25 from the second state to the first state.

[0054] Preferably, in this embodiment, the lock housing 22 is provided with a connecting plate 223, the limiting member 25 is provided with a connecting groove 254, the connecting groove 254 has an end wall opposite to the connecting plate 223, the first elastic member 26 is arranged in the connecting groove 254, the first end of the first elastic member 26 abuts against the connecting plate 223, and the second end of the first elastic member 26 abuts against the end wall, so that the structure is compact and simple, and the installation of the first elastic member 26 is convenient; specifically, when the plurality of door leaves 1 are in the unfolded position, the limiting member 25 is subjected to The push block 212 pushes the limiter 25 to move from the first state to the second state, and the first elastic member 26 is deformed under pressure. When the multiple door leaves 1 slide from the expanded position to the stored position, the push block 212 and the limiter 25 are separated, and the first elastic member 26 can restore the elastic deformation to reset the limiter 25 from the second state to the first state. Moreover, when the limiter 25 is in the first state, the elastic force of the first elastic member 26 is conducive to keeping the limiter 25 in the first state, thereby avoiding the limiter 25 from shaking.

[0055] Preferably, in this embodiment, the first elastic member 26 is a compression spring; indeed, in some other embodiments, the first elastic member 26 may also be, but not limited to, a disc spring or elastic rubber, etc., which can be selected according to actual needs and is not limited here.

[0056] like Figures 4 to 8As shown, specifically, in this embodiment, the lock housing 22 includes a main housing 221 and an end housing 222, the end housing 222 is connected to one side of the main housing 221, the main housing 221 is fixed to the vertical frame 11 of the door leaf 1, the lock tongue 23 slides to connect the main housing 221, the above-mentioned connecting plate 223 is arranged on the end housing 222, the end housing 222 is provided with an opening 2221, the lock tongue 23 can move between an extended position and a retracted position relative to the opening 2221; when the lock tongue 23 is in the extended position, the lock tongue 23 extends out of the opening 2221; when the lock tongue 23 is in the retracted position, the lock tongue 23 retracts into the opening 2221.

[0057] Preferably, in this embodiment, the limit member 25 is slidably connected to the end shell 222 along the sliding direction of the door leaf 1, so that when multiple door leaves 1 slide to the unfolded position, the push block 212 can more smoothly push the limit member 25 from the first state to the second state, thereby making the sliding of the limit member 25 more stable.

[0058] like Figures 4 to 8 As shown, specifically, in the present embodiment, the limit member 25 includes a sliding body 251 and two connecting arms 252, the sliding body 251 is slidably connected to the end shell 222 along the sliding direction of the door leaf 1, the two connecting arms 252 are respectively connected to the upper and lower sides of the sliding body 251, and the above-mentioned connecting groove 254 is arranged on the sliding body 251; preferably, the two connecting arms 252 are both protruding with the above-mentioned cantilever 253, and the above-mentioned notch 231 is respectively arranged on the upper and lower sides of the lock tongue 23; when the limit member 25 is in the first state, the two cantilevers 253 are respectively located in the two notches 231, so that the lock tongue 23 can be more stably prevented from sliding from the retracted position to the extended position.

The two first elastic members 26 are respectively arranged in the two connecting grooves 254 to reliably reset the limit member 25 from the second state to the first state by elastic force.

[0062] Preferably, in this embodiment, the end shell 222 is also provided with two avoidance grooves 227. When the limit member 25 is in the second state, the two cantilevers 253 can be respectively inserted into the two avoidance grooves 227, so as to avoid collision and interference between the limit member 25 and the end shell 222 during the sliding process from the first state to the second state.
