[0035] refer to Figures 1 to 15 According to a preferred embodiment of the rotary elevator door device of the present invention, it should be noted that the structure of the rotary elevator door device is as follows: Figure 1As shown, it includes a door frame assembly and two door panel assemblies 400, the two door panel assemblies 400 being rotatably disposed within the door frame assembly.

[0036] Specifically, the door frame assembly includes two upright assemblies 10, a crossbeam assembly 20, and a sill 30. The two upright assemblies 10 are arranged opposite each other and spaced apart by a predetermined distance. The crossbeam assembly 20 is located on top of the upright assemblies 10, and both ends of the crossbeam assembly 20 are engaged with the sides of the two upright assemblies 10 that are close to each other. The sill 30 is located on the ground, and both ends of the sill 30 are engaged with the sides of the two upright assemblies 10 that are close to each other.

[0037] It is worth mentioning that the crossbeam assembly 20 includes a first cover plate 21 and a crossbeam frame 22. The crossbeam frame 22 has a cavity structure 201 with an opening. Both ends of the cavity structure 201 are connected to the outside. The first cover plate 21 is coverably disposed at the opening of the cavity structure 201 and closes the cavity structure 201. It is also worth mentioning that the bottom wall forming the cavity structure 201 has multiple first guide strips 2011, and the bottom wall also has two oppositely arranged first insertion holes 203 and two oppositely arranged first mounting grooves 202. The two first insertion holes 203 are located in the middle section of the crossbeam frame 22, and the two first mounting grooves 202 are located on the side opposite to each other of the two first insertion holes 203. It is also worth mentioning that the first mounting grooves 202 and the first insertion holes 203 are both connected to the outside.

[0038] It is worth mentioning that the rotary elevator door device also includes a door lock mechanism, which is disposed within the cavity structure 201. Within the cavity structure 201, there is also a movable plate 100 and at least one first fastening component 200 disposed on the movable plate 100. The movable plate 100 is disposed above the first guide bar 2011, and the bottom of the first fastening component 200 engages with the first guide bar 2011, while the top of the first fastening component 200 engages with the movable plate 100. Specifically, the first fastening component 200 includes a slider and a screw. The slider is slidably connected to the first guide bar 2011, and the screw passes through the movable plate 100 and is threadedly connected to the slider. The first fastening component 200 can be tightened or loosened by rotating the screw, thereby limiting the position of the movable plate 100. The door lock mechanism is disposed on the movable plate 100 to move synchronously with the movable plate 100.

[0039] Specifically, the door lock mechanism includes a housing assembly 30, which includes an outer shell 31 and a second cover plate 32. The outer shell 31 has a cavity 3101 with an opening. The second cover plate 32 is coverably disposed at the opening of the cavity 3101 to close the cavity 3101. Specifically, the remaining components of the door lock mechanism are all disposed inside the cavity 3101.

[0040] Specifically, the door lock mechanism includes a door lock assembly 40, which is disposed within the cavity 3101. More specifically, the door lock assembly 40 includes a drive assembly, which comprises a mounting plate 41, a first drive component 42, and a circuit board 43. The mounting plate 41 is fixed within the cavity 3101, and both the first drive component 42 and the circuit board 43 are mounted on the mounting plate 41, near the second cover plate 32. A reduction gear 44 is also provided on the side of the mounting plate 41 facing away from the first drive component 42. The end of the first drive component 42 facing away from the second cover plate 32 passes through the mounting plate 41 and meshes with the reduction gear 44. Figure 7 As shown, the reduction gear component 44 is composed of a large gear component and a small gear component, and the drive assembly also includes an unlocking paddle 45. The unlocking paddle 45 is meshed with the small gear component, and the unlocking paddle 45 is rotatably mounted on the mounting plate 41. That is, when the first drive component 42 drives the reduction gear component 44 to rotate, the unlocking paddle 45 rotates synchronously, and its rotation direction is determined by the rotation direction of the first drive component 42. It is worth mentioning that the first drive component 42 is implemented as a motor, specifically a stepper motor, which has a self-locking force to ensure that it is not easily rotated due to other factors.

[0041] Specifically, the door lock mechanism further includes a lifting assembly 50, which includes a lifting plate 51 and locking tongues 52 disposed on the two lifting plates 51, with the two locking tongues 52 arranged opposite to each other and spaced apart by a predetermined distance. The top of each lifting plate 51 has a bent portion with a guide hole, and the lifting assembly 50 includes a fixing rod 53. The top of the fixing rod 53 is fixed to the top of the outer casing, and the bottom wall forming the cavity 3101 also has a mounting platform 31011 and two second guide bars 31012, which are arranged opposite to each other and located on the upper side of the mounting platform 31011. The bottom of the fixing rod 53 abuts against the mounting platform 31011, and the bottom of the mounting platform 31011 also has a positioning groove with an opening. A limiting nut is disposed in the positioning groove, and the limiting nut is threadedly connected to the end of the fixing rod 53, thus limiting the position of the fixing rod 53 by two-point positioning. Specifically, the lifting assembly 50 further includes a sliding sleeve 54, which is slidably fitted onto the fixed rod 53. The top of the sliding sleeve 54 passes through the guide hole and is fixedly connected to the bent portion. Additionally, one side of the sliding sleeve 54 has a first protrusion 541 located between the two second guide bars 31012, ensuring the movement path of the sliding sleeve 54. When the lifting plate 51 moves up and down, the sliding sleeve 54 moves synchronously. It should be noted that the bottoms of the two locking tongues 52 respectively pass through the first insertion hole 203 and are positioned externally.

[0042] In addition, the top of the lifting plate 51 also has an extension, and a magnet assembly is installed at the extension. The circuit board 43 is also provided with two sensing units that are arranged vertically and spaced apart. That is, when the magnet assembly is facing one of the sensing units, the lifting plate 51 stops moving.

[0043] It should be noted that the door lock mechanism also includes a socket assembly 60, which includes a contact socket, a contact plug, and a support plate. One end of the contact plug is fixed to the support plate, and the end of the support plate facing away from the contact plug is disposed on the lifting plate 51 and spaced at a predetermined distance from the first driving component 42. The contact plug is configured to cooperate with the contact socket, that is, when the lifting plate 51 descends to a predetermined height, the contact plug is pressed down a predetermined distance to cooperate with the contact socket, thereby ensuring the insertion depth of the lock tongue 52.

[0044] It is worth mentioning that the door lock mechanism includes a triangular lock 70, which is rotatably disposed within the cavity 3101. One end of the triangular lock 70 engages with the second cover plate 32, and the other end engages with the bottom wall forming the cavity 3101. The bottom of the lifting plate 51 also has an open recessed cavity, with the triangular lock 70 engaging with the recessed cavity. Furthermore, the outer wall of the triangular lock 70 also has a second protrusion 71, which is configured to press the lifting plate 51 to lift it, thereby opening the door lock mechanism by manual control.

[0045] It should be noted that the unlocking lever 45 has a toggle part 451, which abuts against the lower side of the bent portion. That is, the unlocking lever 45 raises or lowers the height of the lifting plate 51 by rotation, while the rotation angle of the unlocking lever 45 is limited by the two sensing units mentioned above. It should also be noted that the lifting assembly 50 includes an elastic element 55, which is sleeved on the sliding sleeve 54. One end of the elastic element 55 abuts against the bent portion, and the other end abuts against the housing. That is, the lifting plate 51 is reset by the weight of the remaining components of the lifting assembly 50 and the force of the elastic element 55.

[0046] It is worth mentioning that, such as Figure 2 The rotary elevator door device shown also includes two switch assemblies 80, each disposed within one of the first mounting slots 202. Notably, each switch assembly 80 includes a moving contact and a stationary contact. The two stationary contacts are located on the top of the door panel assembly 400, and the two moving contacts are respectively disposed within the two first mounting slots 202. Specifically, when the two door panel assemblies 400 are closed, the two moving contacts engage with the two stationary contacts, thus confirming the door panel assemblies 400 are fully closed via the two switch assemblies 80. The switch assemblies 80 can be implemented as magnetic switches.

[0047] It is necessary that two second driving components 300 are also provided in the cavity structure 201. The two second driving components 300 are respectively close to both ends of the crossbeam frame 22, and the two second driving components 300 are also respectively cooperating with the two door panel assemblies 400. The second driving components 300 are configured to drive the corresponding door panel assembly 400 to rotate by a predetermined angle. It is worth mentioning that the above-mentioned second driving components 300 are motors.

[0048] Specifically, such as Figure 11 and 12As shown, each of the column assemblies 10 has a fixing plate 11 and a disassembly plate 12. The fixing plate 11 has a first connecting wall 11 and a second connecting wall 12. The first connecting wall 11 and the second connecting wall 12 are arranged perpendicularly. The side of the two first connecting walls 11 that is close to each other is fixedly installed to both ends of the crossbeam frame 22, and both ends of the sill 30 are also fixedly installed to the side of the two first connecting walls 11 that is close to each other. It should also be noted that a pivot protection column 500 is installed on the side of the two first connecting walls 11 that is close to each other. The top of the pivot protection column 500 cooperates with the crossbeam frame 22, and its bottom directly abuts against the sill 30.

[0049] It is worth mentioning that the end of the second connecting wall 12 facing away from the first connecting wall 11 also has a first pressing part, and the end of the first connecting wall 11 also has a second pressing part. The disassembly plate 12 is L-shaped, and the inner side of the disassembly plate 12 has a first pressure-bearing part and a second pressure-bearing part. The first pressing part is fastened to the first pressure-bearing part, and the second pressing part is fastened to the second pressure-bearing part to limit the position of the disassembly plate 12. Specifically, during installation, the first and second pressure-bearing parts can be deformed by pressing, so that the disassembly plate 12 can be fastened to the fixing plate 11. Conversely, the disassembly plate 12 can be removed by prying one end, which facilitates subsequent maintenance. Since the disassembly plate 12 and the fixing block are quick-connect structures, during installation, the disassembly plate 12 can be removed first, and then the entire rotating elevator door device can be directly fixed to the connecting bracket at the shaft opening by screws. Then, the disassembly plate 12 can be directly fastened to achieve quick installation of the elevator door.

[0050] It should be noted that both door panel assemblies 400 have a door hinge structure 4001, which is respectively engaged with two pivot protection columns 500. The top of the door hinge structure 4001 is engaged with the corresponding second drive component 300, and the bottom of the door hinge structure 4001 has a shaft. The bottom of the sill 30 is provided with two oppositely arranged connecting pieces 600, and each connecting piece 600 has a bearing. The shaft passes through the sill 30 and engages with the corresponding bearing.

[0051] It is worth mentioning that, such as Figure 13-15 As shown, each of the column assemblies 10 further includes a second fastening assembly 13. The two second fastening assemblies 13 respectively cooperate with the two second connecting pieces 600 to limit the position of the connecting pieces 600, so as to prevent the door hinge structure 4001 from tilting due to factors such as weight during the opening of the door panel assembly 400.

[0052] Specifically, the second fastening assembly 13 includes a snap-fit ​​plate 131, a second fastener 133, and two third fasteners 134. The snap-fit ​​plate 131 is disposed on the first connecting wall 11 and close to the bottom of the first connecting wall 11. The snap-fit ​​plate 131 also has an insertion part, and the connecting piece 600 also has an insertion groove. The insertion part cooperates with the insertion groove. The second fastener 133 passes through the snap-fit ​​plate 131 and the first connecting wall 11 in sequence and is threadedly connected to one end of the sill 30. The other two third fasteners 134 are also threadedly connected to one side of the sill 30 and abut against the side wall of the connecting piece 600. That is, by rotating the two third fasteners 134, the connecting piece 600 is squeezed to increase the force on the connecting piece 600, thereby ensuring that the door hinge structure 4001 is always in a vertical state during rotation.

[0053] It should also be noted that the two switch assemblies 80 are implemented as auxiliary switches, and the door lock assembly 40 is implemented as the main switch. The main switch and the two auxiliary switches are connected in series. That is, when the main switch and the two auxiliary switches are confirmed, the two door panel assemblies 400 are in a closed and locked state, and the elevator can only operate at this time. Safety is ensured by means of the above method.

[0054] In summary, the rotary elevator door device described in the embodiments of this application is explained, which provides advantages such as elevator miniaturization and the ability to use both single and double latches.

[0055] It is worth mentioning that, in this embodiment, the rotary elevator door device has a simple structure, does not involve complex manufacturing processes or expensive materials, and is highly economical. At the same time, for manufacturers, the rotary elevator door device provided in this application is easy to produce and inexpensive, which is more conducive to controlling production costs and further facilitates product promotion and use.

[0056] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functional and structural principles of the present invention have been demonstrated and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from these principles.
