[0029] The present application will be further described in detail below in conjunction with the accompanying drawings through specific embodiments. Similar elements in different embodiments are denoted by related similar element numbers. In the following embodiments, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods.

For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operation steps involved in each embodiment can also be reordered or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and the drawings are only for clearly describing a certain embodiment, and do not mean that they are essential components and / or sequences.

[0031] The serial numbers assigned to the components herein, such as "first", "second", etc., are only used to distinguish the objects described, and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0032] For the waterproof treatment of the elevator hoistway entrance, sandbags are generally used for protection at present, that is, multiple sandbags need to be manually carried and placed at the elevator entrance, which increases the working intensity of the operators. At the same time, the sides and the ground of the elevator entrance cannot be completely sealed by the sandbags, and the water or fireproof foam liquid will also enter the elevator hoistway.

[0033] See Figures 1-7 As shown, the water-blocking device provided by the present application includes: a blocking main body 10, a sealing assembly 20, an operating member 30, a driving mechanism 40, and a sealing block 50.

[0034] The blocking main body 10 is provided with a first end 11 and a second end 12 along its length direction, and the sealing assembly 20 is disposed at the bottom of the blocking main body 10 or disposed at the bottom and the first end 11 of the blocking main body 10, that is, the sealing assembly 20 can be disposed at the bottom of the blocking main body 10, or can be disposed both at the bottom and the first end 11 of the blocking main body 10.

[0035] The driving mechanism 40 is fixed to the blocking main body 10 and connected to the operating member 30. The driving mechanism 40 can be operated through the operating member 30 to output a linear motion along the length direction of the blocking main body 10 towards the first end 11 and the second end 12, or a linear motion towards the second end 12. In other words, the driving mechanism 40 can output a linear motion along the length direction of the blocking main body 10 towards the first end 11 and the second end 12, or can output a linear motion towards the second end 12.

[0036] Of course, when the sealing assembly 20 is only provided at the bottom of the blocking main body 10, the driving mechanism 40 can output a linear motion towards the first end 11 or a linear motion towards the second end 12. When the sealing assembly 20 is provided at the bottom and the first end 11 of the blocking main body 10, the driving mechanism 40 can output a linear motion along the length direction of the blocking main body 10 towards the second end 12.

[0037] The sealing block 50 is connected to the power output end of the driving mechanism 40. The driving mechanism 40 can drive the sealing block 50 to move outside the first end 11 and the second end 12 along the length direction of the blocking main body 10, or move outside the second end 12.

[0038] In other words, when the driving mechanism 40 outputs a linear motion along the length direction of the blocking main body 10 towards the first end 11 and the second end 12, the driving mechanism 40 has two power output ends. At this time, sealing blocks 50 are provided at both power output ends, and the two sealing blocks 50 can be respectively driven and moved outside the first end 11 and the second end 12 through the driving mechanism 40. When the driving mechanism 40 outputs a linear motion along the length direction of the blocking main body 10 towards the second end 12, the driving mechanism 40 only has a power output end towards the second end 12. Connecting the sealing block 50 to this power output end, the sealing block 50 can be driven and moved outside the second end 12 through the driving mechanism 40.

[0039] In a specific embodiment, the water-blocking device is placed at the elevator entrance to block water or foam liquid. More specifically, when a fire occurs in a building, an operator can place the water-blocking device at the elevator entrance to prevent the water or foam liquid used for extinguishing fire from entering the elevator hoistway. When sealing components 20 are provided at both the bottom and the first end 11 of the blocking body 10, and the sealing block 50 is moved to the outside of the second end 12 by the drive of the drive mechanism 40, the sealing components 20 at the bottom and the first end 11 of the blocking body 10 seal the ground at the elevator entrance and the elevator door frame facing the first end 11, while the sealing block 50 seals the elevator door frame facing the second end 12. When a sealing component 20 is provided at the bottom of the blocking body 10, and the sealing block 50 is moved to the outside of the first end 11 and the second end 12 by the drive mechanism 40, the sealing component at the bottom of the blocking body 10 seals the ground at the elevator entrance, and the two sealing blocks 50 respectively seal the elevator door frames facing the first end 11 and the second end 12.

[0040] In the above two sealing methods, the blocking body 10 can effectively block water, and the sealing components 20 and the sealing block 50 seal the gaps at the corresponding positions, effectively preventing the water or foam liquid for extinguishing fire from entering the elevator hoistway.

[0041] In this embodiment, the drive mechanism 40 has two power output ends, and sealing blocks 50 are provided at both of the two power output ends. At the same time, a sealing component 20 is only provided at the bottom of the blocking body 10. Refer to Figure 8 and Figure 9 As shown, the drive mechanism 40 drives the two sealing blocks 50 to move to the outside of the first end 11 and the second end 12 respectively, and are respectively in contact with the elevator door frames 200 facing the first end 11 and the second end 12 to seal the gaps between them and the elevator door frames 200, while the sealing component 20 at the bottom of the blocking body 10 seals the gap between the blocking body 10 and the ground 100 to prevent the water or foam for extinguishing fire from entering the elevator hoistway.

[0042] In an embodiment of the present application, the sealing block 50 is made of materials such as rubber or silica gel, has a certain elastic deformation, and can be in close contact with the elevator door frame 200.

[0043] To ensure that the sealing block 50 can continuously contact the elevator door frame, refer to Figure 2 and Figure 3 As shown, the water-blocking device provided in this embodiment further includes: a locking mechanism 60, which is connected to the drive mechanism 40 and is used to keep the drive mechanism 40 driving the sealing block 50 in the position of moving to the outside of the first end 11 and the second end 12, or in the position of moving to the outside of the second end 12, so as to lock the drive mechanism 40.

[0044] Of course, after use, to reset the drive mechanism 40, the water-blocking device provided in this embodiment further includes: an unlocking assembly 70, which is connected to the locking mechanism 60 and is used to unlock the locking mechanism 60 so as to reset the drive mechanism 40, and then drive the two sealing blocks 50 to move into the interior of the first end 11 and the second end 12.

[0045] See Figures 2-6 As shown, the drive mechanism 40 includes a fixing member 41, two movable members 42, a connecting rod 43, and a shear connecting rod 44. The fixing member 41 is fixed to the blocking main body 10. The two movable members 42 are respectively arranged above and below the fixing member 41. One end of the connecting rod 43 is hinged to the upper movable member 42, and the other end of the connecting rod 43 is hinged to the fixing member 41. One end of the shear connecting rod 44 is hinged to both movable members 42, and the other end of the shear connecting rod 44 is hinged to the sealing block 50. The operating member 30 is connected to the upper movable member 42. By applying a force to the upper movable member 42 through the operating member 30, the shear connecting rod 43 is elongated under the action of the connecting rod 42 and the shear connecting rod 44, and then a linear motion along the length direction of the blocking main body 10 can be output, so as to drive the sealing block 50 to move. The locking mechanism 60 is connected between the upper or lower movable member 42 and the fixing member 41.

[0046] In this embodiment, two shear connecting rods 44 are provided, respectively located at both ends of the fixing member 41 in the length direction. The shear connecting rods 44 form the power output ends of the drive mechanism 40, and sealing blocks 50 are arranged on both shear connecting rods 44.

[0047] In a specific embodiment, an operator can apply pressure through the operating member 30 by stepping on it with the foot, etc., so that the two movable members 42 move towards the fixing member 41 under the action of the connecting rod 43 and the shear connecting rod 44. The two shear connecting rods 44 then output a linear motion along the length direction of the blocking main body 10 towards the first end 11 or the second end 12, so as to drive the two sealing blocks 44 to move to the outside of the first end 11 or the second end 12 respectively.

[0048] After unlocking the locking structure 60 through the unlocking assembly 70, to enable the drive mechanism 40 to automatically reset, the drive mechanism 40 provided in this application further includes an elastic reset assembly 45. The elastic reset assembly 45 is connected between the upper and lower movable members 42 and is used to reset the upper and lower movable members 42 after the unlocking assembly 70 unlocks the locking mechanism 60, and then the shear connecting rod 44 can be driven to retract.

[0049] In this embodiment, two elastic return assemblies 45 are disposed between the upper and lower movable members 42 to provide a more uniform force on the upper and lower movable members 42. In a preferred embodiment, the elastic return assemblies 45 are compression springs that store elastic potential energy as the upper and lower movable members 42 move toward the fixed member 41. When the unlocking assembly 70 unlocks the locking structure 60, the compression springs release the elastic potential energy, causing the upper and lower movable members 42 to return to their original positions.

[0050] See also Figures 4-6 As shown, the locking mechanism 60 includes a stop member 61, a lock tongue 62 and a lock tongue elastic member 63. One end of the stop member 61 is fixed to the upper movable member 42, and the other end of the stop member 61 is movably connected to the fixed member 41 and can move synchronously with the upper movable member 42. The lock tongue 62 is slidably arranged on the fixed member 41, and the lock tongue elastic member 63 is arranged between the lock tongue 62 and the fixed member 41. The stop member 61 is provided with a plurality of locking portions 611 along its length direction to lock the lock tongue 62 with the locking portion 611.

[0051] Specifically, when the movable part 42 moves toward the fixed part 41, the stop part 61 moves synchronously, and under the action of the lock tongue elastic part 63, the lock tongue 62 can always maintain a state of facing and resisting the stop part 61. When the movable part 42 moves into place, the lock tongue 62 can be locked with the locking part 611 to limit the displacement of the movable part 42 toward the fixed part 41.

[0052] In a specific embodiment, the locking portion 611 is a lock groove arranged on the stop member 61, which can ensure that the stop member 61 does not form a locking relationship with the lock tongue 62 during the synchronous movement with the movable member 42, and only forms a locking relationship with the locking portion 611 when the movable member 42 moves in a direction away from the fixed member 41.

[0053] In the present application, the unlocking assembly 70 includes a linkage member 71, the middle part of the linkage member 71 is rotatably mounted on the fixing member 41, one end of the linkage member 71 is rotatably connected to the lock tongue 62, and the other end of the linkage member 71 extends to the outside of the blocking body 10. By operating the other end of the linkage member 71, the linkage member 71 is rotated around the part connected to the fixing member 41, and then the lock tongue 62 is driven to move by the rotational connection between one end of the linkage member 71 and the lock tongue 62. It should be noted that when the lock tongue 62 is driven to move synchronously, the lock tongue 62 can be disengaged from the locking portion 611 to unlock the lock.

[0054] For ease of operation, in this embodiment, the unlocking assembly 70 further includes a toggle member 72 , which is disposed at the other end of the linkage member 71 , so that the linkage member 71 can be rotated around the connection portion between the linkage member 71 and the fixing member 41 by toggling the toggle member 72 .

[0055] In this embodiment, the locking tongue 62 is provided with a notch 621. One end of the linkage member 71 is provided with at least one arc-shaped protrusion 711 along its radial direction. When the arc-shaped protrusion 711 contacts the side wall of the notch 621, the locking tongue 62 can be moved during the rotation of the linkage member 71 around its connection position with the fixing member 41 through the contact between the arc-shaped protrusion 711 and the side wall of the notch 621.

[0056] In this application, two locking mechanisms 60 are provided. Correspondingly, arc-shaped protrusions 711 are provided at the connection parts of the linkage member 71 and the locking tongues 62 of the two locking mechanisms 60. The two locking mechanisms 60 are respectively located on the opposite sides of the fixing member 41. In this way, during the rotation of the linkage member 71 around its connection position with the fixing member 41, the two locking tongues 62 can be driven to move synchronously.

[0057] In an embodiment of this application, as Figure 2 and Figure 9 shown, the blocking body 10 has a central installation channel 13. The driving mechanism 40 is installed inside the central installation channel 13. The two axial ends of the central installation channel 13 are respectively a first end 11 and a second end 12. At the bottom of the first end 11 and the second end 12, or at the bottom of the second end 12, there is a notch 131. One side of the sealing block 50 facing the notch 131 is provided with a protrusion 51. The protrusion 51 is located at the notch 131 and can be flush with the sealing assembly 20 at the bottom of the blocking body 10, so as to seal the gap between it and the ground when the sealing block 50 moves to the outside of the first end 11 and the second end 12.

[0058] In this application, as Figure 8 shown, barbs 51 are also provided on both sides of the sealing block 50. During the process of moving the sealing block 50 to the outside of the first end 11 and the second end 12, due to the action of friction, it is more conducive to the barbs 51 to expand, so as to form a seal with the blocking body 10 more easily and prevent water or foam liquid from entering the central installation channel 13 inside the blocking body 10. On the contrary, when the sealing block 50 is retracted into the central installation channel 13 inside the blocking body 10, the barbs 51 are in a compliant state, and the barbs 51 are more likely to contract, making the resistance smaller during retraction and making it easier to retract.

[0059] In summary, in the water-blocking device provided by the present application, when a fire breaks out in a building, an operator can place the water-blocking device at the elevator entrance to prevent water or foam liquid used for fire extinguishing from entering the elevator hoistway. When sealing components are provided at both the bottom and the first end of the blocking body, and the sealing block is moved to the outside of the second end by the drive of the drive mechanism, the sealing components at the bottom and the first end of the blocking body seal the ground at the elevator entrance and the elevator door frame facing the first end, while the sealing block seals the elevator door frame facing the second end. When a sealing component is provided at the bottom of the blocking body, and the sealing block is moved to the outside of the first end and the second end by the drive mechanism, the sealing component at the bottom of the blocking body seals the ground at the elevator entrance, and the two sealing blocks respectively seal the elevator door frames facing the first end and the second end.

[0060] The above uses specific examples to elaborate on the present utility model, which is only used to help understand the present utility model and is not intended to limit the present utility model. For those skilled in the technical field to which the present utility model belongs, according to the idea of the present utility model, several simple deductions, deformations or substitutions can also be made.
