DETAILED DESCRIPTION

[0030] The present invention is further described with reference to the accompanying drawings and embodiments:

[0031] Example:

[0032] A lifting vertical partition system, such as Figures 1 to 8As shown, it includes a fixed frame 11, a lifting device and a partition plate assembly 51. The lifting device includes a winch assembly 12, a pulley assembly 21, a limit assembly 31, and a connecting assembly 41. The winch assembly 12 and the pulley assembly 21 are both installed on the fixed frame 11. The connecting assembly 41 is located below the pulley assembly 21. There are 3 pulley assemblies 21 in total, and 7 pulley assemblies are arranged below each pulley assembly 21. The connecting assembly 41 is connected to the limit assembly 31. The limit assembly 31 limits the moving direction of the connecting assembly 41, so that the connecting assembly 41 and the partition plate assembly 51 can only move vertically. The number of partition plate assemblies 51 is the same as the number of connecting assemblies 41. Different partition plate assemblies 51 are respectively installed on different connecting assemblies 41. The pulley assembly 21 includes a pulley frame 22 and 7 suspended fixed pulleys 23. The winch assembly 12 is connected to a pull rope 13. The pull rope 13 is respectively wound around different suspended fixed pulleys 23 and connecting assemblies 41. The 7 suspended fixed pulleys 23 and the 7 connecting assemblies 41 are alternately distributed in the extension direction of the pull rope 13. The end of the pull rope 13 away from the winch assembly 12 is fixedly connected to the fixed frame 11.

[0033] The seven connection components 41 are arranged vertically, and the connection component 41 close to the pulley frame 22 is connected to the pulley frame 22. The distance between the surface profiles of any two suspended fixed pulleys 23 projected on the horizontal plane is greater than the diameter of the pull rope 13. Among any two suspended fixed pulleys 23: the suspended fixed pulley 23 with a shorter pull rope 13 between the hoisting component 12 is located above the other suspended fixed pulley 23, and the suspended fixed pulley 23 with a shorter pull rope 13 between the hoisting component 12 is located on the side of the other suspended fixed pulley 23 close to the connection component 41 in the horizontal direction.

[0034] The connecting assembly 41 includes a connecting frame 42, two upper connecting plates 43 and two lower connecting plates 44. The two upper connecting plates 43 are respectively located on both sides of the connecting frame 42, and the two lower connecting plates 44 are respectively located on both sides of the connecting frame 42. The connecting frame 42 is rotatably connected with a movable pulley 45 that abuts against the pull rope 13. The lower connecting plate 44 is hinged to the connecting frame 42, and the upper connecting plate 43 is hinged to the lower connecting plate 44. The partition plate assembly 51 includes two upper partition plates 52 and two lower partition plates 53. The two upper partition plates 52 are respectively located on both sides of the connecting frame 42, and the two lower partition plates 53 are respectively located on both sides of the connecting frame 42. The upper partition plates 52 and the lower partition plates 53 are respectively installed on the upper connecting plates 43 and the lower connecting plates 44. The connecting frame 42 is hinged to the upper connecting plate 43 adjacent to the lower connecting plate 43, and the upper connecting plate 43 close to the pulley frame 22 is hinged to the pulley frame 22. An upper gear 46 and a lower gear 47 are fixedly connected to the upper connecting plate 43 and the lower connecting plate 44 respectively. The upper gear 46 and the lower gear 47 are meshed with each other. The number of teeth of the upper gear 46 is the same as that of the lower gear 47.

[0035] The hoisting assembly 12 includes a mounting frame 14, a power mechanism 15 and three drums 16. The power mechanism 15 is fixedly mounted on the mounting frame 14. The three drums 16 are all rotatably connected to the mounting frame 14. The three drums 16 are fixed to each other and coaxially arranged. The output end of the power mechanism 15 is connected to the drum 16. The three drums 16 are all connected to the pull ropes 13 respectively wound around different pulley assemblies 21. The power mechanism 15 includes a power motor 17 and a reducer 18. The reducer 18 is mounted on the mounting frame 14. The power motor 17 is mounted on the reducer 18. The output shaft of the power motor 17 is fixed to the input shaft of the reducer 18. The output shaft of the reducer 18 is fixed to the drum 16. The power motor 17 drives the drum 16 to rotate through the reducer 18 to achieve the function of driving the drum 16 to reel in and release the pull rope 13.

[0036] The pulley frame 22 is rotatably connected to a guide fixed pulley 24, and the pull rope 13 is wound around the guide fixed pulley 24. Since the positions of the mutually fixed drums 16 need to be staggered, the extension direction of the pull ropes 13 connected to different drums 16 can be adjusted by the guide fixed pulley 24, thereby reducing the friction force on the pull rope 13 and improving the stability and reliability of the pull rope 13.

[0037] The limiting assembly 31 includes a positioning frame 32 and six scissor frames 34 respectively installed on different connecting assemblies 41. The scissor frames 34 include two scissor arms 35 whose middle parts are both hinged to the connecting assembly 41. The positioning frame 32 includes two positioning arms 33 both hinged to the pulley frame 22. The two positioning arms 33 are respectively hinged to the two scissor arms 35, and the length of the positioning arm 33 is half the length of the scissor arm 35. The limiting assembly 31 also includes a limiting frame 36. The limiting frame 36 and the scissor frames 34 are respectively connected to different connecting assemblies 41. The limiting frame 36 includes two limiting arms 37 both hinged to the connecting assembly 41 farthest from the pulley frame 22. The two limiting arms 37 are respectively hinged to the two scissor arms 35, and the length of the positioning arm 33 is half the length of the scissor arm 35.

[0038] The upper partition plate 52 and the lower partition plate 53 are both slidably connected with a seal 61, and the seal 61 is a sealing strip made of rubber material. The upper partition plate 52 and the lower partition plate 53 are both installed with a driving mechanism 62 that drives the seal 61 to move in the horizontal direction. The driving mechanism 62 includes a mounting seat 63, a driving motor and a screw rod. The driving motor (not shown in the figure) and the screw rod (not shown in the figure) are both located in the mounting seat 63. The driving motor is fixedly connected to the mounting seat 63, the screw rod is threadedly connected to the mounting seat 63, the screw rod is rotationally connected to the seal 61 and axially linked, and the output shaft of the driving motor is fixedly connected. When the driving motor is in operation, it drives the screw rod to rotate, so that the screw rod drives the seal 61 to move on the upper partition plate 52 and the lower partition plate 53, thereby realizing the function of driving the seal 61 to move.

[0039] During use, when the partition system needs to be folded, the winch assembly 12 reels the pull rope 13, and the pull rope 13 changes the extension direction through the guide fixed pulley 24 and the suspension fixed pulley 23, and pulls the movable pulley 45 around which the pull rope 13 is wound, and the movable pulley 45 drives the connecting frame 42, the lower connecting plate 44 and the upper connecting plate 43 to move upward, thereby driving the lower partition plate 53 and the upper partition plate 52 respectively installed on the lower connecting plate 44 and the upper connecting plate 43 to move upward, and at the same time, as the connecting frame 42 moves upward, the upper partition plate 52 and the lower partition plate 53 are turned over and closed. In the process of the connecting frame 42 moving together, the scissor arm 35 is driven to rotate, and the parallelogram mechanism formed by the scissor arm 35 makes the distance between any two adjacent connecting frames 42 equal, so that the flip angles of different upper connecting plates 43 and lower connecting plates 44 are consistent and smoothly move upward.

[0040] This embodiment has the following advantages:

[0041] When the hoist assembly 12 releases the pull rope 13, the connection assembly 41 and the partition plate assembly 51 move downward under the action of gravity, realizing the function of controlling the partition plate assembly 51 to move downward, so that the partition plate assembly 51 is unfolded in a direction away from the pulley assembly 21, so that the function of separating spaces can be realized through the partition plate assembly 51. When the hoist assembly 12 reels and pulls the pull rope 13, the distance between the connection assembly 41 and the pulley assembly 21 is shortened, so that the pull rope 13 drives the connection assembly 41 and the partition plate assembly 51 to move in a direction close to the pulley assembly 21 and get closer, thereby achieving the function of retracting the partition plate assembly 51 upward, so that the space separated by the partition plate assembly 51 is connected.

[0042] By connecting seven connecting components 41 with different partition board components 51, different connecting components 41 provide support forces to different partition board components 51 respectively, and effectively disperse the weight of different partition board components 51 on different connecting components 41, thereby ensuring the structural stability between the partition board components 51 and the connecting components 41, preventing the structural stability and reliability of the partition board components 51 and the connecting components 41 from being affected by the excessive weight of the total partition board components 51, and solving the problem of poor structural strength between the partition board and the connecting structure in traditional partition doors and windows.

[0043] By setting the hoisting assembly 12, the pulley assembly 21 and the pull rope 13, a plurality of different connection assemblies 41 can be driven to move by a single hoisting assembly 12 connected to the pull rope 13, thereby achieving the function of simultaneously driving the movement of a plurality of connection assemblies 41 by a single hoisting assembly 12. It is not necessary to set up a plurality of hoisting assemblies 12, which reduces costs and facilitates installation, and also achieves the advantages of simple and reliable structure.

[0044] The suspended fixed pulleys 23 and the connecting components 41 are alternately distributed in the extension direction of the pull rope 13, so that the load applied by the connecting components 41 and the partition plate components 51 on the pull rope 13 can be more evenly dispersed on different suspended fixed pulleys 23, thereby preventing some suspended fixed pulleys 23 from being subjected to excessive loads that affect their service life, and also improving stability.

[0045] The connecting assembly 41 is arranged vertically so that the load transferred from the connecting assembly 41 to the pulley assembly 21 through the pull rope 13 can be more balanced, thereby making the force on the pulley assembly 21 more balanced and effectively reducing the shaking of the connecting assembly 41 and the partition plate assembly 51 during the vertical movement, thereby improving the stability and reliability of the pulley assembly 21.

[0046] In the process of pulling the connecting component 41 upward by the pull rope 13, since the suspended fixed pulley 23 and the connecting component 41 are alternately distributed in the extension direction of the pull rope 13, and the connecting component 41 located at the top is wound around a section of the pull rope 13 close to the hoisting assembly 12, the section of the pull rope 13 close to the hoisting assembly 12 needs to resist a larger resistance to drive all the connecting components 41 and the partition plate assembly 51 to move, so the section of the pull rope 13 close to the hoisting assembly 12 is subjected to a larger pulling force; and the connecting component 41 located at the bottom is connected to a section of the pull rope 13 away from the hoisting assembly 12, so the section of the pull rope 13 away from the hoisting assembly 12 is subjected to a smaller pulling force. The suspended fixed pulley 23 which is wound around a section of the pull rope 13 near the hoisting assembly 12 is arranged at a position which is closer to the connecting assembly 41 in the horizontal direction than other suspended fixed pulleys 23, so that the pull rope 13 which is subjected to a larger pulling force can be close to the top of the connecting assembly 41, thereby reducing the angle between the pulling direction provided by the pull rope 13 with a larger pulling force and the vertical direction, thereby reducing the force component in the horizontal direction, reducing the pulling force required to be provided by the hoisting assembly 12 when pulling the entire connecting assembly 41 upward, and reducing the force between the suspended fixed pulley 23 and the pulley frame 22 when tightening the pull rope 13, thereby effectively improving the structural stability and reliability among the pull rope 13, the suspended fixed pulley 23 and the pulley frame 22.

[0047] The movable pulley 45 abuts against the pull rope 13, which can effectively reduce the friction between the connecting assembly 41 and the pull rope 13, thereby improving the stability and reliability of the pull rope 13 during its movement. When the pull rope 13 drives the connecting frames 42 to move upward, the distance between the connecting frames 42 is shortened, so that the adjacent upper partition boards 52 and lower partition boards 53 are turned over and closed, thereby facilitating the storage of the upper partition boards 52 and lower partition boards 53.

[0048] The connecting frame 42 is hinged to the adjacent upper connecting plate 43 below it, so that when two adjacent connecting frames 42 approach each other, the upper partition plate 52 and the lower partition plate 53 between the two connecting frames 42 are driven to flip and close together, thereby achieving the effect of conveniently storing the upper partition plate 52 and the lower partition plate 53.

[0049] By arranging the upper gear 46 and the lower gear 47 with the same number of teeth, the turning angles of the upper connecting plate 43 and the lower connecting plate 44 are equal, and the turning of the upper partition plate 52 and the lower partition plate 53 is smoother.

[0050] The two mutually fixed reels 16 are driven to rotate simultaneously by the power mechanism 15 , so that the three pull ropes 13 can be controlled simultaneously by the three reels 16 , which makes it easy to control the pull ropes 13 and to install them.

[0051] The scissor arms 35 are of equal length, so that the scissor arms 35 between the two connecting frames 42 form a parallelogram mechanism, and the two opposite scissor arms 35 are parallel to each other. When the connecting frame 42 drives one of the scissor arms 35 to rotate, the scissor arm 35 can drive the other scissor arms 35 to rotate at the same time, and the two opposite scissor arms 35 in the parallelogram mechanism can maintain a state of being parallel to each other. Since the middle part of the scissor arm 35 is hinged to the connecting frame 42, the parallelogram mechanism can drive the adjacent parallelogram mechanism to move through the rotation of the scissor arm 35, so that all the scissor arms 35 are linked in sequence and rotate at the same speed. During the rotation process, the scissor arm 35 can drive the two connecting frames 42 connected to the parallelogram mechanism to move closer to and away from each other, and the directions of movement are the same, so that the connecting frame 42 can be driven to move through the linkage between the scissor arms 35, so that the distance between any two adjacent connecting frames 42 is equal, and the effect of limiting the movement direction of the connecting frame 42 is achieved, so that the connecting frame 42 can only move vertically.

[0052] The length of the positioning arm 33 is half of the length of the scissor arm 35, so that when the connecting frame 42 approaches the pulley frame 22, the angles of rotation of the positioning arm 33 and the scissor arm 35 are equal, and the connecting frame 42 can only move vertically.

[0053] During the process of the pull rope 13 driving the connecting assembly 41 to move, the distance between the connecting frames 42 is shortened, so that the scissor arms 35 rotate, and the linkage between the scissor arms 35 can drive other connecting frames 42 to move synchronously, so that the connecting frames 42 move simultaneously. Since the distance between the connecting frames 42 is equal, the flip angles of the upper partition board 52 and the lower partition board 53 between any two connecting plates are equal, so that the upward movement of the connecting frames 42, the upper partition board 52 and the lower partition board 53 is more stable, which can reduce the shaking and vibration during the movement, play a noise reduction effect, and has the effect of improving stability and reliability.

[0054] During the rotation process, the scissor arm 35 can drive the positioning arm 33 to rotate, thereby driving the connection component 41 farthest from the pulley frame 22 to move through the rotation of the scissor arm 35 and the positioning arm 33, so that the connection component 41 farthest away can move vertically at the same time as other connection components 41.

[0055] The length of the positioning arm 33 is half of the length of the scissor arm 35, so that when the connecting frame 42 approaches the pulley frame 22, the angles of rotation of the positioning arm 33 and the scissor arm 35 are equal, and the connecting frame 42 can only move vertically.

[0056] When the partition plate assembly 51 moves downward and unfolds, the driving mechanism 62 drives the seal 61 to move away from the partition plate assembly 51, so that the seal 61 abuts against other objects, thereby blocking the gap between the partition plate assembly 51 and other objects through the seal 61, thereby achieving a sealing effect.

[0057] In summary, after reading the present invention document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the present invention without creative mental work, which all fall within the scope of protection of the present invention.
