Description

Technical Field

[0001] This application relates to the technical field of partition doors, and in particular to a large electric partition door and its installation method. Background Technology

[0002] A partition door is a type of door used in interior design to separate spaces; it serves to connect, guide, and transition between two separate spaces, acting as a link between them. Large shopping malls and showrooms often use partition doors to divide interior spaces and areas. However, due to the large size and height of the spaces, multiple partition door units are typically used, secured by hanging.

[0003] Regarding the aforementioned technologies, the inventors discovered that existing solutions lack an effective steering structure during the folding and storage of partition doors. Most rely on electric steering mechanisms, which are complex and cannot effectively fold the partition door after it has been folded. Furthermore, the applicant found that individual door structures are difficult to process and transport due to their large length, and spliced ​​door panels lack integrity, affecting usability. Therefore, a large electric partition door and an improved installation method are needed. Summary of the Invention

[0004] To address the inconvenience of installing large partition doors and their tendency to deform during use, this application provides a large electric partition door and its installation method.

[0005] This application provides a large electric partition door and its installation method, which adopts the following technical solution:

[0006] A large electric partition door includes several partition door units and a guide rail for moving and installing the partition door units. The partition door units are installed independently of each other. The partition door units are connected to the guide rail by hanging wheels, which drive the partition door units to move on the guide rail. The guide rail is fixed to the ceiling by multiple sets of track fixers. Each partition door unit has two hanging wheels connected to its top. A steel keel is provided inside the partition door unit. Support frames are provided at both ends of the steel keel, and the support frames are connected by struts. The struts are configured as upper struts and lower struts, and the upper struts and lower struts drive the corresponding support frames to move up and down through a telescopic mechanism. Limiters are provided on the steel keel to limit the movement of the struts.

[0007] The guide rail is composed of a main rail and a deflector end. The deflector end is equipped with an outer rail and an inner rail. A deflector rail is provided at the connection between the outer rail and the inner rail and the deflector end. During use, the two parallel rails can be used to achieve a concealed effect by cooperating with the side of the ceiling structure.

[0008] The partition door unit can be moved by the top hanging wheels and drive motor, and adjacent partition door units can be attached side to side to separate the interior space.

[0009] By adopting the above technical solution, the corresponding partition door unit can be folded and stored during use by setting up a reversible track and inner and outer tracks for storage. During storage, the partition door unit can be tilted to save storage space. During use, the telescopic mechanism can drive the support rods at both ends to move, thereby providing stable support and preventing swaying during use due to the height of the door and lack of effective fixation. The support at both ends can also effectively isolate sound transmission. During implementation, the adjustment and coordination between the telescopic mechanism and the support rods is such that the working ends on both sides of the telescopic mechanism synchronously drive the upper and lower support rods to retract and extend. The telescopic mechanism can be selected as an electric or manual adjustment structure, and the number of supporting rod structures and telescopic mechanisms can be set according to the usage requirements.

[0010] Optionally, the outer track and the inner track are arranged in parallel, and the adjacent width of the outer track and the inner track is less than the straight-line distance between adjacent hanging wheels in a single partition door unit.

[0011] By adopting the above technical solution, it is possible to stack individual partition door units at an angle during the storage process, and the stacked partition door units are relatively parallel. In the overall design, the hidden panel room can be set up separately to cooperate with the turning structure and the change track, which reduces the movement distance of the partition door and optimizes the aesthetics of the space design, thus meeting the spatial layout needs of different places.

[0012] Optionally, the partition door unit and the hanging wheel can rotate at an angle via a steering structure, with a maximum rotation angle of 60°.

[0013] By adopting the above technical solution, the partition door unit can be stored during use, and the angle within 60° can be easily moved, so as not to make it inconvenient to move during use due to the angle being too large.

[0014] Optionally, two sets of movable wheels are arranged side by side on both sides of the hanging wheel, and a steering wheel is provided on the hanging wheel that is relatively far away from the door closing fixed seat. A fixed connecting seat is provided between the hanging wheel and the steering wheel, and a rotating bearing is provided inside the fixed connecting seat. The upper end of the hanging wheel moves in the guide rail under the drive of the traction motor through rollers.

[0015] By adopting the above technical solution, the device can move within the guide rail via rollers under the drive of the traction motor during use.

[0016] Optionally, the outer side of the steering wheel is provided with a toothed groove, and the inner side of the reversing track is provided with an arc-shaped rack that engages with the toothed groove on the outer side of the steering wheel. When the hanging wheel moves to the reversing track, the steering wheel meshes with the arc-shaped rack, so that the steering wheel rotates during the movement, thereby causing the partition door unit connected to the lower end to deflect and form an inclined angle with the outer and inner tracks.

[0017] By adopting the above technical solution, corresponding racks are respectively installed on the outer side of the outer track and the inner side of the inner track during implementation. When the partition door retracts, as the partition door unit moves to the reversing end, its front-end hanging wheel first enters the reversing end. Upon entry, the corresponding steering wheel contacts the rack, and after the steering wheel engages, it rotates, causing the partition door unit connected to the lower end to turn relative to the main track and enter the outer track. When the deviation angle is sufficient for the rear hanging wheel to enter the inner track, the steering wheel disengages from the rack, and the partition door unit retracts relative to the retracting end of the guide rail. When the partition door unit moves outward, when the hanging wheel on the inner track moves to the reversing track at the connection point of the inner track, the steering wheel on the hanging wheel engages with the rack, thereby causing the partition door unit to deflect, ensuring that the partition door unit deflects at the corresponding position during movement.

[0018] Optionally, the steel keel of the isolation unit is filled with sound-insulating cotton, and the side frame of the steel keel is sealed with a sealing strip. The outer surfaces on both sides of the steel keel are provided with an outer finish, and the outer finish is made of a sound-insulating material.

[0019] By adopting the above technical solution, filling the interior of the isolation unit with sound-absorbing cotton and using the exterior finish to decorate the isolation unit can improve the separation effect between different spaces, and filling with sound-absorbing cotton can reduce the interaction of sound between the two sides.

[0020] Optionally, a sealing strip is provided on the outer side of the support frame. The sealing strip is composed of a rubber flexible joint and a pressure strip, with the rubber flexible joint wrapped around the outside of the pressure strip.

[0021] By adopting the above technical solution, the pressure strip and rubber flexible joint are used in conjunction with the contact surface during use to achieve close contact, thereby effectively separating the space and improving the isolation effect between the two parts of the space. During use, the sealing strip and pressure strip, with the cooperation of the support frame, respectively contact the inner top surface of the guide rail upward and the corresponding ground of the partition door downward.

[0022] Optionally, an interlocking groove is provided on the side of the adjacent partition door unit, and a rubber flexible joint is provided in the interlocking groove, and a support base is provided at the bottom of the partition door unit.

[0023] By adopting the above technical solution and setting a matching structure on the side of the partition door unit, the overall effect of the partition door after it is closed can be improved. Additionally, the overall sound insulation effect can be enhanced, and magnetic structures can be set at the matching points to better match the combined effect during use.

[0024] Optionally, the track fixer is used to horizontally fix the guide rail. The track fixer includes a fixing angle iron fixed to the top of the floor, and a fixing seat is provided at the lower end of the fixing angle iron. The fixing seat is connected and limited to the limiting groove at the upper end of the guide rail by a screw and a nut.

[0025] By adopting the above technical solution, one end of the fixed angle iron is fixed to the top layer during use, and expansion nails are used to fix it. Then, the guide rail and the fixed seat are connected by a screw. During implementation, the length of the screw is adjusted to correct the levelness of the guide rail. Multiple nuts are set on the screw to cooperate with each other to effectively limit the movement, which facilitates adjustment and improves the stability after fixing.

[0026] Optionally, the upper end of the hanging wheel moves within the guide rail via rollers driven by a traction motor.

[0027] By adopting the above technical solution, the bidirectional structure of the hanging wheel facilitates installation, and a steering structure can be provided at both ends of the hanging wheel during use, so that the partition door unit can be turned at the turning end when stored and stacked, thereby meeting the usage needs.

[0028] Optionally, the bottom surface of the support frame at the bottom end of the steel keel is provided with casters, and multiple casters are arranged side by side.

[0029] By adopting the above technical solution, a movable wheel is installed at the bottom of the support frame during use. The support frame is moved downward by the strut, so that the movable wheel can contact the ground and provide support during the movement of the isolation unit. This avoids the door from deforming due to the large volume and weight of a single door body swinging during the movement.

[0030] An installation method for a large electric partition door includes the following steps:

[0031] S1. Determine the direction of the partition and the route for laying the guide rail;

[0032] S2. Install the track positioner, connect the guide rail, and adjust the level and connection tightness;

[0033] S3. Install the partition door units sequentially from the reversing end;

[0034] S4. The partition door units are tested sequentially for movement and positioning.

[0035] S5. After the partition door unit is installed, move it as a whole to test the sound insulation effect.

[0036] Optionally, the partition door unit in S4 is filled with sound insulation cotton and decorated after installation.

[0037] In summary, this application includes at least one of the following beneficial technical effects:

[0038] 1. In this technical solution, when the partition door unit moves outward during use, the hanging wheel on the inner track moves to the deflection track at the connection of the inner track. The steering wheel on the hanging wheel cooperates with the rack and pinion to drive the partition door unit to deflect, ensuring that the partition door unit deflects at the corresponding position during the movement.

[0039] 2. The telescopic mechanism can move the support rods at both ends, thereby providing stable support and preventing the door from shaking during use due to its height and lack of effective fixation. Furthermore, the support at both ends can effectively isolate sound transmission.

[0040] 3. By filling the interior of the isolation unit with sound-absorbing cotton and decorating the isolation unit with an exterior finish, the separation effect between different spaces can be improved, and the sound-absorbing cotton filling can reduce the interaction of sound between the two sides;

[0041] 4. By setting up a steering track, the partition door unit can be stored during use, thereby reducing the external space used, improving aesthetics, and facilitating the maintenance and replacement of the partition door unit;

[0042] 5. A lifting platform is set up in the storage area to facilitate the support of the partition door, making it easy to inspect and adjust the door. It can also adapt to different positions for support. In addition, the cross-type lifting platform structure is used during the installation process to facilitate support and obtain a thinner support structure for easy installation under the door.

[0043] 6. The door structure adopts a modular assembly, which facilitates installation and transportation, reduces production costs, and the two-section structure will not affect the implementation of the partition door's upper and lower isolation structure during the implementation process.

[0059] The present application will be further described in detail below with reference to the accompanying drawings.

[0060] This application discloses a large electric partition door, mainly used for dividing spaces in large commercial complexes or performance venues. (See also...) Figure 1 , Figure 2 and Figure 8 A large electric partition door includes several partition door units 4 and guide rails 2 for moving and installing the partition door units. The partition door units 4 are installed independently of each other. The partition door units 4 are connected to the guide rails 2 by hanging wheels 3. The hanging wheels 3 drive the partition door units 4 to move on the guide rails 2. The guide rails 2 are fixed to the ceiling by multiple sets of track fasteners 1. Each partition door unit 4 has two hanging wheels 3 connected to its top. The partition door units 4 can move in cooperation with the drive motor via the top hanging wheels 3, and adjacent partition door units 4 can be side-mounted and assembled to separate interior spaces.

[0061] During implementation, multiple partition door units 4 are set up independently and move sequentially on the guide rail. When partitioning, they are connected in pairs to form a whole and create an overall partition effect.

[0062] Please see Figure 1 , Figure 2 , Figure 7 , Figure 10 , Figure 11 and Figure 12 The partition door unit 4 and the hanging wheel 3 can rotate at an angle through a steering structure. During implementation, the steering structure consists of a wheel seat 31 and a steering wheel 35. In use, the wheel seat 31 cooperates with the steel keel 42, allowing the steel keel 42 to move on the guide rail 2. During implementation, the steering wheel 35 and the wheel seat 31 are connected by a hanger rod. When the steering wheel 35 rotates, it drives the hanger rod to rotate synchronously, thus causing the partition door unit 4 to rotate synchronously during use. The maximum rotation angle is 60°. Two sets of moving wheels 34 are arranged side-by-side on both sides of the hanging wheel 3, and a steering wheel 35 is installed on the hanging wheel 3 that is relatively far from the door closing fixing seat. The hanging wheel 3 and the steering wheel 35... A fixed connecting seat 36 is provided, and a rotating bearing is provided inside the fixed connecting seat 36. The upper end of the hanging wheel 3 moves in the guide rail 2 under the drive of the traction motor through the roller. The bottom of the hanging wheel 3 is provided with a connecting rod 37 that is connected to the partition door unit 4. The bottom of the connecting rod 37 is fixedly connected to the support seat 47 at the upper end of the partition door unit 4. The steering wheel 35 is fixed on the connecting rod 37, and the other end of the connecting rod 37 is connected to the inner ring of the rotating bearing in the fixed connecting seat 36. During use, the connecting rod 37 can rotate relative to the hanging wheel 3. When the steering wheel 35 rotates, the connecting rod 37 can synchronously drive the partition door unit 4 to rotate synchronously. The outer side of the steering wheel 35 is provided with a toothed groove 351.

[0063] Please refer to Figure 8 , Figure 9 and Figure 11 The inner side of the deflecting track 25 is equipped with an arc-shaped rack 26 that engages with the outer tooth groove of the steering wheel 35. The tooth height of the two ends of the arc-shaped rack 26 gradually increases along the middle direction, and it can normally mesh with the tooth groove 351 of the steering wheel 35 at its middle position. The contact end of the tooth groove 351 of the steering wheel 35 and the arc-shaped rack 26 can quickly mesh, avoiding gear misalignment that would prevent timely meshing and thus affect the rotation of the door. When the hanging wheel 3 moves to the deflecting track 25, the tooth groove 351 on the steering wheel 35 meshes with the arc-shaped rack 26, causing the steering wheel 35 to rotate during the movement, thereby causing the partition door unit 4 connected to the lower end to deflect at an angle to the outer track 23 and the inner track 24. In the implementation process, the deflecting track 25 is equipped with a rack of corresponding length. When the partition door retracts, as the partition door unit 4 moves to the reversing end 22, the hanging wheel 3 at its front end first enters the reversing end 22. Upon entry, the corresponding steering wheel 35 contacts the rack. After the steering wheel 35 engages, it rotates, thereby driving the partition door unit 4 connected to the lower end to turn relative to the main track 21 and enter the outer track 23. When the deviation angle is sufficient for the rear hanging wheel to enter the inner track, the steering wheel 35 disengages from the rack, and the partition door unit 4 retracts relative to the retraction end of the guide rail 2. When the partition door unit 4 moves outward, the hanging wheel 3 on the inner track 24 moves to the deflection track 25 at the connection of the inner track 24. The steering wheel 35 on the hanging wheel 3 engages with the rack to drive the partition door unit 4 to deflect, ensuring that the partition door unit 4 deflects at the corresponding position during the movement. During implementation, the engagement length between the rack and the steering wheel 35 should not allow the steering wheel to rotate more than 60°. Excessive rotation angle will put a large load on the drive device. Therefore, setting the steering angle to no more than 60 degrees is optimal. Depending on the size of the gear tooth groove, different combinations of meshing teeth with different clearances and lengths can be used to extend the steering path of the door and avoid the problem of insufficient steering path leading to the inability to achieve steering.

[0064] Reference Figure 2 and Figure 3 The partition door unit 4 is equipped with a steel keel 42. The steel keel 42 is filled with sound-insulating cotton 45, and the sides of the steel keel 42 are equipped with frame sealing strips 46. The outer surfaces of both sides of the steel keel 42 are equipped with exterior finishes 41, which are made of sound-insulating material. In practice, filling the interior of the partition unit with sound-insulating cotton and using exterior finishes to decorate the partition unit improves the separation effect between different spaces, and filling with sound-insulating cotton reduces the interaction of sound between the two sides.

[0065] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5The steel keel 42 has support frames 49 at both ends, and the support frames 49 are connected by struts 43. The partition door unit 4 has support seats 47 at both ends, which are fixed to the ends of the steel keel 42. During use, they are used to limit the decorative panel and provide suspension support for the overall structure. The steel keel 42 is equipped with limiters 44 to limit the struts 43. During use, the limiters 44 are fixed with screws at the contact position between the struts 43 and the steel keel 42 to ensure that the position of the struts 43 does not deviate during the extension and retraction process. The limiters 44 are designed with support planes at both ends and a cylindrical through hole in the middle. The struts 43 move inside the through hole. The struts 43 are configured as upper struts 431 and lower struts 432. The ends of the upper struts 431 and lower struts 432 away from the telescopic mechanism 5 are connected to the support frames 49. The upper struts 431 and lower struts 432 are connected to the corresponding support frames 49 by the telescopic mechanism 5. 9. The support frame 49 is moved up and down. A sealing strip 48 is provided on the outer side of the support frame 49. The sealing strip 48 is composed of a rubber flexible joint 481 and a pressure strip 482, and the rubber flexible joint 481 is wrapped around the outside of the pressure strip 482. During use, the telescopic mechanism 5 can drive the support rods 43 at both ends to move, so that the support frame 49 extends outward and contacts the bottom surface of the upper guide rail 2 and the ground, thereby providing stable support and avoiding shaking during use due to the height of the door and the lack of effective fixation. The pressure strip 482 and the rubber flexible joint 481 cooperate with the contact surface to achieve tight contact, thereby effectively separating the space during use and improving the isolation effect between the two parts of the space. During use, the rubber flexible joint 481 and the pressure strip 482, with the cooperation of the support frame 49, respectively contact the inner top surface of the guide rail 2 upward and contact the ground corresponding to the partition door downward. After the two ends are supported, sound transmission can be effectively isolated.

[0066] Furthermore, multiple casters 34 can be installed on the bottom surface of the support frame 49 at the bottom end of the steel keel 42. During use, the casters 34 are installed at the bottom of the support frame 49, and the support frame 49 is moved downward by the strut 43, so that the casters 34 can contact the ground. This provides support during the movement of the partition door unit 4, and avoids deformation of the door due to lack of support during the movement of a single door with a large volume and weight.

[0067] A sealing rubber flexible joint is also provided at the end of the support base 47 to contact the support frame 49, which reduces the entry of dust or other solid debris into the door connection during use and affects the use of the door.

[0068] During implementation, the adjustment and coordination between the telescopic mechanism and the support rod 43 is as follows: the two working ends of the telescopic mechanism 5 synchronously drive the upper support rod 431 and the lower support rod 432 to retract and extend. During use, the telescopic mechanism 5 can be either electrically or manually adjusted. The number of support rods 43 and the telescopic mechanism can be set according to the usage requirements. When using the electric method, it needs to be combined with a controller and input circuit. When using the manual method, the stirring rod can be connected to the side of the partition door unit 4 to operate the use status of the support rod.

[0069] The sides of adjacent partition door units 4 are provided with interlocking grooves, and rubber flexible joints are installed within the interlocking grooves. The mating structure on the sides of partition door units 4 improves the overall effect after the partition doors are closed. It also enhances the overall sound insulation. Furthermore, magnetic structures can be installed at the mating points for better matching and combination during use.

[0070] Please refer to Figure 8 The guide rail 2 is composed of a main rail 21 and a deflector end 22. The deflector end 22 is equipped with an outer rail 23 and an inner rail 24, which are arranged in parallel. The adjacent width of the outer rail 23 and the inner rail 24 is less than the straight-line distance between adjacent hanging wheels 3 in a single partition door unit 4. A deflector rail 25 is provided at the connection between the outer rail 23 and the inner rail 24 and the deflector end 22. During use, the two parallel rails can accommodate the tilted stacking of a single partition door unit during storage. Furthermore, the deflector design allows for the separate setting of concealed compartments, reducing the movement distance of the partition door and optimizing the aesthetic design of the space. The ceiling structure can be integrated with the side of the guide rail 2 to achieve a concealed effect. In implementation, a lifting platform (not shown in the diagram) is provided below the deflector end 22. When the partition door unit is stored at the deflector end, the lifting platform moves upward, abutting against the bottom support seat 47 of the partition door unit 4 to support the entire partition door unit 4. During implementation, the deflection end 22 adopts a track with a strength superior to that of the main track 21, and a landslide is set on the ground near the main track 21 at the deflection end 22. The height of the landslide gradually increases from the main track 21 to the deflection end 22, so that when the partition door unit 4 moves to the landslide, it is slightly lifted upward, thereby facilitating the upper gear set of the partition door unit 4 to rotate.

[0071] Please refer to Figure 6 and Figure 7The track fixer 1 is used to horizontally fix the guide rail 2. The track fixer 1 includes a fixing angle iron 13 fixed to the top of the floor, and a fixing seat 11 is provided at the lower end of the fixing angle iron 13. The fixing seat 11 is connected to the limiting groove at the upper end of the guide rail 2 through the cooperation of a screw rod 12 and a nut for limiting. In use, one end of the fixing angle iron 13 is fixed to the top floor and fixed with expansion bolts. Then, the guide rail 2 is connected to the fixing seat through a screw rod. During implementation, the length of the screw rod is adjusted to correct the levelness of the guide rail. Multiple nuts are set on the screw rod to cooperate with each other for effective limiting, which facilitates adjustment and improves the stability after fixing. The upper end of the hanging wheel 3 moves within the guide rail 2 through rollers driven by the traction motor.

[0072] The steel keel can be configured as a modular structure, assembled from multiple parts.

[0073] According to the technical solution indicated in the embodiment, the sound insulation cotton 45 and the outer surface 41 can be replaced with flame-retardant materials, and gypsum board can be used to fill and support the outer surface 41 to form a fireproof partition door. The rubber flexible joint 481 and the pressure strip 482 can be replaced with a barrier seat to prevent smoke from moving from the bottom side of the isolation space during use.

[0074] According to the technical solution indicated in the embodiment, at least one of the partition door units 4 is provided with an opening at the bottom, and a door frame and door (not shown in the figure) are provided at the opening. The width of the door frame and door body shall not exceed 80% of the width of the partition door. Adjacent partition door units with the same door body can be provided with a double door method. When this solution is adopted, the support structure and telescopic structure of the corresponding partition door unit can be moved to the edge part.

[0075] Please refer to Figure 8 , Figure 13 and Figure 14 The outer track 23 and inner track 24 are respectively provided with partition door support frame 6 on the ground. The bottom plate of the partition door support frame 6 is connected to the ground through a sliding track. There is a gap between the top plate of the partition door support frame 6 and the partition door unit 4. A shear frame 62 is provided between the bottom plate 64 and the top plate 63 of the partition door support frame 6. There are two sets of shear frames 62, and the two sets of shear frames 62 are connected by a connecting rod. The partition door support frame 6 is also provided with a drive structure 61. The drive structure 61 is fixedly set on one side of the bottom plate 64. The drive device drives the shear frame 62 to rotate through the sliding screw, so that the top plate 63 rises and falls relative to the bottom plate 64. A support pad 65 is provided above the top plate 63. The support pad 65 is made of rubber and has a groove on the top. During the installation process, the top support pad 65 tilts upward along the end near the deflection track, so that the partition door unit 4 can move gradually from the track between the partitions to the front track during the implementation process.

[0076] When storing large partition doors in a storage room, the door body is tilted at 60°. During storage, relying solely on the upper track for suspension can easily damage the track. Furthermore, during maintenance and replacement, the door body needs separate support to prevent deviation during disassembly. The partition door support frame 6 can support the door body during storage. A track is installed below the partition door support frame 6, allowing for movement of the support frame 6 during installation. The partition door support frame 6 uses a shear frame 62 for height adjustment. This not only lowers the large partition door but also provides greater support height during installation. This not only supports the partition door but also elevates the height of the operators during maintenance, facilitating repairs.

[0077] An installation method for a large electric partition door includes the following steps:

[0078] S1. Determine the direction of the partition and the route for laying the guide rail:

[0079] Before construction, select appropriate partition locations based on the two spaces and reserve space for concealed partitions to determine the route of guide rail 2 and the movement position of partition door unit 4.

[0080] S2. Install the track positioner, connect the guide rail, and adjust the level and connection tightness:

[0081] According to the planned route and selected intervals, the track fixing device 1 is fixed in sequence. First, the fixing angle iron 13 is fixed to the top of the floor with expansion bolts.
