The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

A movable stereographic image according to an embodiment of the present invention is described in detail below with reference to the accompanying drawings.

The invention provides a three-dimensional statue, which comprises a plurality of upright posts 100 arranged vertically as shown in the figure, wherein each upright post 100 is provided with a blade unit 200, the shaft 100 is provided with a blade driving unit 300 for driving the blade unit 200, the lower end of the shaft 100 is mounted on a bearing unit 400, by driving the carrying unit 400 to move the column 100 in the horizontal direction, thereby driving the vane units on the upright posts 100 to mutually cooperate to form an overall statue outer contour when the upright posts 100 are mutually gathered, so as to show the overall statue modeling of audiences in visual effect, and when the respective uprights 100 are reset to be away from each other, the blade units 200 on the uprights 100 are driven by the respective blade driving units 300 to enable the blades in the blade units 200 to be rearranged and combined to form a single pattern, for example, a flower state is shown in fig. 13. Finally, the original single three-dimensional statue can present at least two different modeling displays. All of the blade units 200 on the column 100 may be collectively referred to as moving parts on the stereographic.

The first embodiment is as follows:

as shown in fig. 3, the blade unit 200 in the three-dimensional statue includes a plurality of blades 201, all the blades 201 are sleeved outside the upright 100, and the blades 201 are sequentially arranged at intervals along the length direction of the upright 100. At least one blade 201 or all blades 201 in all the blades 201 described above include a blade main body 2011 and a support ring 2012 used for bearing the blade main body 2011, the support ring 2012 is sleeved outside the column 100 and is connected with the column 100, the blade main body 2011 is installed on the support ring 2012, and the blade main body and the support ring 2012 are in circumferential rotation fit along the column 100 along the axial limit of the column 100, the blade main body 2011 is provided with a blade motor 301 for driving the blade main body 2011 to rotate relative to the support ring 2012, that is, the blade main body 2011 is rotated by the blade motor 301 in the blade driving unit 300. Of course, the above-mentioned driving components for driving the blade body 2011 to rotate may also be a hydraulic motor or the like, and on this basis, the following includes, but is not limited to, taking the conventional blade motor 301 as an example to facilitate the description of the movement process of the support ring 2012.

In order to form the outer contour of the three-dimensional statue, the outer edge of each blade body 2011 arranged in sequence needs to be constructed to preset the outer contour pattern of the three-dimensional statue, so the outer contour of each blade body 2011 on the same column 100 in the horizontal direction is adjusted according to the design requirement of the contour shape, but the matching between each blade body 2011 and the support ring 2012 can adopt the same or different connection mechanisms, which is allowed.

Specifically, blade main part 2011 comprises upper blade board and lower floor's blade board, upper blade board and lower floor's blade board interval set up and mutual fixed connection, thereby blade main part 2011 goes up along self thickness direction and runs through the upper blade board and the lower floor's blade board of blade main part 2011 in proper order and form the mounting hole, the size and the support ring 2012 phase-match of mounting hole, support ring 2012 is spacing between upper blade board and lower floor's blade board along the thickness direction of blade main part 2011, just support ring 2012 passes through bearing and blade main part 2011 normal running fit.

Preferably, as shown in fig. 11, the blade motor 301 is provided between the upper blade plate and the lower blade plate of the blade body 2011, so that the built-in design of the blade motor 301 at least has wind and rain protection functions. One of the examples of the above-described driving of the support ring 2012 by the vane motor 301: the output shaft of the vane motor 301 is provided with a driving gear, an arc-shaped rack is arranged on the outer circumference of the support ring 2012, the driving force of the vane motor 301 is transmitted to the support ring 2012 through the engagement between the driving gear and the arc-shaped rack, and the support ring 2012 is fixedly connected with the upright post 100, so that the vane body 2011 drives the vane motor 301 to rotate around the upright post 100 under the pushing of the reaction force.

Preferably, the support ring 2012 can be a part of the vane, so that the vane is divided into a movable part and a fixed part, i.e., the support ring 2012 as the fixed part is connected to the upright 100, and the vane body 2011 as the movable part is rotationally fitted with the support ring 2012. In addition, the above-mentioned support ring 2012 can be a separate component, and the blade and the upright post 100 are rotatably engaged with each other through the separate component, that is, the support ring 2012 as the separate component is fixed to the upright post 100, and the blade and the support ring 2012 are rotatably engaged with each other, in the sense that the entire blade rotates around the upright post 100, and of course, the blade motor 301 is also provided in the blade, and the output shaft of the blade motor 301 is engaged with the support ring 2012 through the transmission gear to drive the blade to rotate relative to the support ring 2012.

Of course, the example discussed with respect to the vanes 201 of the vane unit 200 is that the support ring 301 is rotationally engaged with the mast 100; certainly, in the actual assembly process, it is not strictly required that all the blades adopt the rotatable structural design, and if part of the blades 201 do not need to rotate, the blades 201 do not need to rotate and are directly and fixedly connected with the upright post, and at this time, the common knowledge in the industry is not described herein again, and when all the blades 201 can rotate, part of the blades can be selected to not rotate, so that the blades 201 discussed below are all rotatable.

Example two:

the basic structure is the same as the first embodiment, except that: as shown in fig. 3 to 9, the number of the blades 201 on the single upright post 100 is N, and all the N blades 201 are sequentially divided into M groups of blades, where N is an integer greater than 2, and M is an integer smaller than N and greater than 1. And the blade group with the number of the blades 201 more than 2 in the M blade groups consists of at least one reference blade 201-0 and at least one movable blade 201-S, namely, at least one blade 201 in the blade group is the reference blade 201-0, and the rest blades 201 are the movable blades 201-S. Taking a blade group consisting of 5 blades 201 in the M blade groups as an example, the blade 201 at the middle position in the blade group is a reference blade 201-0, the upper part of the reference blade 201-0 is sequentially provided with a first movable blade 201-S1 and a second movable blade 201-S1 at intervals, and the lower part of the reference blade 201-0 is sequentially provided with a second movable blade 201-S3 and a second movable blade 201-S4 at intervals. The support ring 2012 of the reference vane 201-0 is fixedly connected to the mast 100, and the vane body 2011 of the reference vane 201-0 is rotatably engaged with the support ring 2012 so that the vane body 2011 of the reference vane 201-0 rotates around the mast 100 only in the circumferential direction of the mast 100. Each support ring 2012 of the 4 moving blades 201-S is connected to the column 100 through a corresponding axial moving mechanism, that is, the moving blades 201-S realize axial movement through the axial moving mechanism 302 in the blade driving unit 300, and the support rings 2012 of the moving blades can be driven to move axially along the column 100 through the axial moving mechanism 302, so that the blade main bodies 2011 of the moving blades 201-S can be in rotating fit with the corresponding support rings 2012, so that the blade main bodies 2011 of the moving blades 201-S can rotate circumferentially around the column 100, and the support rings 2012 can drive the blade main bodies 2011 to move axially along the column 100 through the axial moving mechanism 302. The overall effect of the movable blades 201-S is that the blade main bodies 2011 of the 5 blades 201 can rotate around the circumference of the column 100, and meanwhile, the 4 movable blades 201-S can be gathered towards the position of the reference blade 201-0 or reset towards the direction away from the reference blade 201-0.

Preferably, the blade 201 at the intermediate position is set as the reference blade 201-0 in the same blade group in order to make the total stroke of movement of each movable blade 201-S toward the reference blade 201-0 small. Of course, it is not excluded that any blade 201 in the blade group is taken as the reference blade 201-0, for example, in the blade group consisting of 5 blades 201, the first blade 201 from top to bottom may be taken as the reference blade 201-0, and 4 blades 201 located below the reference blade 201-0 are taken as the movable blades 201-S; the second blade 201 from top to bottom can also be used as a reference blade 201-0, 1 blade 201 above the reference blade 201-0 and 3 blades 201 below the reference blade 201-0 can be used as movable blades 201-S; the fourth blade 201 from top to bottom can also be used as a reference blade 201-0, 3 blades 201 above the reference blade 201-0 and 1 blade 201 below the reference blade 201-0 can be used as a movable blade 201-S; the fifth blade 201 from top to bottom can also be used as the reference blade 201-0, and the 4 blades 201 above the reference blade 201-0 are the movable blades 201-S.

Preferably, the total number of blades 201 in a single blade group may be 2, 3, 4, 5, 6 or more.

Further, when the total number of the blades 201 is an odd number, the blade 201 at the middle position is selected as the reference blade 201-0, so that the axial moving path of each movable blade 201-S is small, and errors caused by movement and control difficulty are reduced.

Example three:

the basic structure is the same as the embodiment, and the difference is that: as shown in fig. 14, a virtual reference plane O may be preset instead of the reference blade 201-0 in the blade group consisting of one or more blades, and all the blades 201 in the blade group move toward the reference plane O through the axial moving mechanism 302, so as to achieve the exhibition effect of gathering together to form a flower pattern, or to reset from the flower pattern in the gathered state to the initial state.

In particular, when the number of the blades 201 in a single blade group is even, a reference blade 201-0 cannot be found at the axial middle position, and therefore, it is necessary to set a reference plane O, which may be selected as a plane located at any point in the corresponding region of the blade group along the axis of the mast 100.

Preferably, for the consideration of the symmetry of the force, a midpoint is found at the axially middle position of the blade group, a virtual reference plane O is formed by the midpoint, each blade 201 in the blade group is divided into an upper part and a lower part along the axial direction, thereby facilitating the design of symmetry of the blade 201 in the up-down direction during the movement process, and obviously, after the reference plane O replaces the reference blade 201-0 in the second embodiment, all the blades 201 in the blade group are the movable blades 201-S.

Of course, for the comprehensive consideration of the positions, heights, the association of adjacent components, the moving stroke of the blade 201, etc., it is possible to only set one reference blade 201-0, or set a plurality of reference blades 201-0, or set one reference plane O, or set a plurality of reference planes O, or set a combination of at least one reference blade 201-0 and at least one reference plane O in one blade group, and the selection of the reference plane O and/or the reference blade 201-0 is preferably changed based on the above technical solution of the present application.

Example four:

the basic structure is the same as the embodiment, and the difference is that: as shown in fig. 19, the axial movable mechanism 302 includes a drag chain 3021 extending along the axial direction of the mast 100, the support ring 2012 of the movable blade 201-S is fixedly connected to the drag chain 3021, and the drag chain 3021 moves only along the axial direction of the mast 100, thereby moving the movable blade 201-S fixedly connected to the drag chain 3021 along the axial direction of the mast 100.

Specifically, the traction chain 3021 only moves along the axial direction of the upright 100 and needs a certain limiting mechanism and a traction chain driving mechanism, but the limiting mechanism of the traction chain 3021 may realize a limiting function through an additionally arranged guide rail, a guide groove, a guide wheel, or the like, and the traction chain driving mechanism may be realized through a conventional driving manner such as a motor plus a transmission gear, or a motor plus a chain wheel, or a hydraulic cylinder. It is obvious that the movement of the drag chain 3021 only along the axial direction of the upright 100 can be realized by using various conventional technologies, and those skilled in the art can realize the movement of this drag chain 3021 only along the axial direction of the upright 100 by using the technologies in the prior art even in the well-known field, so that the specific conventional structure for driving the drag chain 3021 is not listed in this embodiment and does not affect the technical reproduction of the movement of the drag chain 3021 only along the axial direction of the upright 100 by those skilled in the art, and therefore, the detailed description thereof is omitted here.

Example five:

the basic structure is the same as the embodiment, and the difference is that: as shown in fig. 2, taking 45 blades 201 on a single upright post 100 as an example, every 5 blades 201 are divided into one blade group, so that the 45 blades 201 are sequentially divided into 9 blade groups from top to bottom, and the blade 201 at the middle position in any one blade group is a reference blade 201-0, the upper and lower sides of the reference blade 201-0 are respectively provided with a previous movable blade 201-S1 and a next movable blade 201-S3, the upper part of the previous movable blade 201-S1 is provided with a second movable blade 201-S2, the lower part of the next movable blade 201-S3 is provided with a second movable blade 201-S4, the moving stroke of the second movable blade 201-S2 towards the reference blade 201-0 is greater than that of the previous movable blade 201-S1, and the moving stroke of the second movable blade 201-S2 is approximately 2 times that of the previous movable blade 201-S1, the moving stroke of the lower second moving blade 201-S4 toward the reference blade 201-0 is greater than that of the next moving blade 201-S3 and the moving stroke of the lower second moving blade 201-S4 is approximately 2 times that of the next moving blade 201-S3. Specifically, the moving stroke of the upper movable blade 201-S1 and the lower movable blade 201-S3 is 350mm, and the moving stroke of the upper movable blade 201-S2 and the lower movable blade 201-S4 is 700 mm.

Example six:

in order to make the outer contour of the plurality of blades on the column 100 visually construct the contour of the three-dimensional statue, such as a human-shaped statue, it is necessary that part or all of the column 100 is bent in a three-dimensional space to present the visual effect of the three-dimensional statue, that is, part or all of the central axis of the column 100 is in a curved state, thereby making part or all of the column 100 present a crank axis. Of course, a crankshaft, whether vertical, straight or curved, is generally referred to as a mast 100.

Example seven:

the basic structure is the same as the fourth embodiment, and the difference is that: as shown in fig. 19 to 21, in order to enable the drag chain 3021 to be applied to the curved mast 100, that is, the length direction of the drag chain 3021 itself extends along the curved axis of the mast 100, in order to avoid interference between the curved portion of the drag chain 3021 and other accessories on the mast 100 and differences in the stroke of the drag chain 3021 in the curved portion, an improved design is made for the structure of the drag chain 3021, where the drag chain 3021 is composed of at least a plurality of roller units and telescopic units alternately arranged in sequence, and both ends of any one telescopic unit are respectively connected with the adjacent roller units through universal joints.

Preferably, in order to reduce the number of the traction chains 3021, the traction chain 3021 may adopt an endless loop structure, the top of the column 100 is provided with a fixed pulley 304 matched with the traction chain 3021, and the upper part of the traction chain 3021 is wound outside the fixed pulley 304, so that one endless traction chain 3021 can form two sections, one section of which ascends and the other section of which descends synchronously after passing through the fixed pulley 304, and thus two sets of traction chain driving mechanisms for driving the traction chain to move can be simplified into one set of traction chain driving mechanism.

Preferably, the traction chain driving mechanism is disposed on the carrying unit 400, the top of the endless traction chain 3021 is wound around the fixed pulley 304, and the bottom of the traction chain may be connected to the traction chain driving mechanism through a reversing wheel, specifically, the driving mechanism may be a motor and a sprocket, and the traction chain is wound around the sprocket and is driven by the motor to rotate to realize forward and reverse pulling on the traction chain.

Preferably, the roller unit and the telescopic unit are provided on the drag chain 3021 for the purpose of facilitating the installation and adjustment of the movable blade, so that when the drag chain 3021 is located at the fixed pulley 304, the roller unit and the telescopic unit do not need to be installed, and the drag chain 3020 can be constructed by using a common chain 3030, and the part of the same drag chain 3021 extending to the carrying unit 400 only needs to be connected with the drag chain driving mechanism on the carrying unit 400, so that the roller unit and the telescopic unit do not need to be provided. Therefore, the whole endless traction chain includes, but is not limited to, at least one roller unit, at least one telescopic unit with adjustable length and at least one end chain 3030 which are sequentially connected end to end. Of course, as the roller unit and the telescopic unit are disposed on the drag chain 3021 as described above, the installation of the movable blade is convenient, and the movable blade is prevented from interfering with the upright or the fixed attachment on the upright while taking into account the movement of the movable blade along the predetermined path, especially when the axis of the upright 100 is curved, the conventional chain pulling will greatly cause the movable blade to contact with the curved portion of the upright 100, which causes damage to the equipment, so the roller unit and the telescopic unit should be the corresponding region of the movable blade disposed on the upright 100. The region of the mast 100 in which the moving blades are located is therefore considered to define an area which is a blade mounting region 305, said blade mounting region 305 being an annular region formed around the axis of the mast 100. The portion of the drag chain 3021 located in the blade mount area 305 is defined as a functional segment, and the roller unit and the telescopic unit constituting the drag chain 3021 are located in the blade mount area 305.

As a preferred example, as shown in the figure, 6 endless drag chains are provided on one column, the 6 endless drag chains are provided at intervals along the circumferential direction of the column 100, and the top of the column 100 is provided with a fixed pulley 304 at a position corresponding to each drag chain. And 6 drag chains each pass through the blade mount area 305, whereby all drag chains 3021 form 12 mutually parallel functional segments within the blade mount area 305, all of which are evenly distributed in the circumferential direction of the mast 100.

In order to realize the translation of the roller unit on the guide rail, as a preferred example, the roller unit includes a roller body 3021-1 and a guide wheel 3021-2 mounted on the roller body 3021-1, the guide wheel 3021-2 includes a first guide wheel 3021-2 'and a second guide wheel 3021-2 "spaced apart in the axial direction of the roller body 3021-1", and a region of the roller body 3021-1 between the first guide wheel 3021-2' and the second guide wheel 3021-2 "is left with a connecting region 3021-3 for connecting the movable blade 201.

Specifically, the number of the first guide wheels 3021 to 2 'and the number of the second guide wheels 3021 to 2 "are four, the four first guide wheels 3021 to 2' are uniformly distributed along the circumferential direction of the roller body 3021 to 1, the four second guide wheels 3021 to 2" are also uniformly distributed along the circumferential direction of the roller body 3021 to 1, and any one of the second guide wheels 3021 to 2 "corresponds to one of the first guide wheels 3021 to 2 'along the axial direction of the roller body 3021 to 1, so that the four first guide wheels 3021 to 2' and the four second guide wheels 3021 to 2" correspond to each other in the axial direction of the roller body 3021 to 1. And the outer circumferential surfaces of the two first guide wheels 3021-2 'and the outer circumferential surfaces of the two second guide wheels 3021-2 ″ of the two first guide wheels 3021-2' corresponding to each other in the axial direction together surround an inner surface of the slide groove slidably engaged with the guide rail. Similarly, the outer circumferential surfaces of the other two first guide wheels 3021-2 'and the outer circumferential surfaces of the two axially corresponding second guide wheels 3021-2 "also jointly surround to form chute inner surfaces in opposite directions, so that two oppositely-oriented chutes jointly formed by the four first guide wheels 3021-2' and the four second guide wheels 3021-2" are matched with two sliding surfaces on the guide rail or are matched with two components of the guide rail in a sliding manner, and finally, not only can the sliding fit of the roller body 3021-1 on the guide rail be well realized, but also the roller body 3021-1 can be restrained on the guide rail, and the risk that the roller body 3021-1 is derailed from the guide rail is reduced. Of course, the above-mentioned guide rail structure needs to be configured to match with both the two sliding grooves, and the adaptive adjustment of the guide rail may be implemented by deforming the guide rail to form different mating surfaces, or by matching a plurality of components of the guide rail, so in this embodiment, after the roller unit is subjected to the above-mentioned structural improvement, the corresponding adjustment of the guide rail that needs to be adapted is simply implemented based on the common knowledge in the field of guide rails, and therefore, details of the guide rail part are not described in detail in this embodiment.

In order to realize the translation of the roller unit on the guide rail, as a preferred example, the roller unit comprises a roller body 3021-1, a position of the roller body 3021-1 corresponding to the guide rail is recessed to form a guide sliding groove matched with the guide rail, and the guide rail is in sliding fit with the sliding groove.

In order to realize the translation of the roller unit on the guide rail, as a preferred example, the roller unit includes a roller body 3021-1, and a sliding block matched with the guide rail is installed on the roller body 3021-1 at a position corresponding to the guide rail, and the guide rail is in sliding fit with the sliding block.

Preferably, the telescopic unit comprises an upper adjusting rod 3021-4, a lower adjusting rod 3021-5 and an adjusting sleeve 3021-6, one end of the upper adjusting rod 3021-4 extends into one end of the adjusting sleeve 3021-6 and is in threaded connection with the adjusting sleeve 3021-6, one end of the lower adjusting rod 3021-5 extends into the other end of the adjusting sleeve 3021-6 and is in threaded connection with the adjusting sleeve 3021-6, and the upper adjusting rod 3021-4 and the lower adjusting rod 3021-5 are synchronously linked along the axial direction of the adjusting sleeve 3021-6 along with the rotation of the adjusting sleeve 3021-6 so that the upper adjusting rod 3021-4 and the lower adjusting rod 3021-5 are relatively close to or away from each other. By adopting the telescopic unit, the length of each position of the drag chain 3021 can be effectively adjusted along the length direction of the drag chain 3021, namely, the distance between two roller units can be adjusted.

The relative movement of the upper and lower adjustment levers 3021-4 and 3021-5 toward and away from each other as the adjustment sleeves 3021-6 are rotated is accomplished in conjunction with the selection of the direction of rotation of the threads between the upper adjustment lever 3021-4 and the adjustment sleeves 3021-6 and the selection of the direction of rotation of the threads between the lower adjustment lever 3021-5 and the adjustment sleeves 3021-6. That is, the upper adjusting rods 3021 to 4 and the lower adjusting rods 3021 to 5 respectively adopt right-handed external threads and left-handed external threads, and the positions corresponding to the upper adjusting rods 3021 to 4 and the lower adjusting rods 3021 to 5 in the adjusting sleeves 3021 to 6 respectively adopt corresponding internal threads, so that the lower adjusting rods 3021 to 5 move downward when the upper adjusting rods 3021 to 4 move upward along with the rotation of the adjusting sleeves 3021 to 6, and the upper adjusting rods 3021 to 4 and the lower adjusting rods 3021 to 5 move away from each other, whereas the lower adjusting rods 3021 to 5 move upward when the upper adjusting rods 3021 to 4 move downward, so that the upper adjusting rods 3021 to 4 and the lower adjusting rods 3021 to 5 move closer to each other.

Preferably, the universal joints comprise male joints 3021 to 7, female joints 3021 to 8, rotating core blocks and rotating shafts, the male joints 3021 to 7 of the two universal joints are fixedly connected with the ends of the upper adjusting rods 3021 to 4 and the lower adjusting rods 3021 to 5, which are positioned outside the adjusting sleeves 3021 to 6, respectively, specifically, the male joint 3021 to 7 of one universal joint and the upper adjusting rod 3021 to 4 are in an integrated structure, and the male joint 3021 to 7 of the other universal joint and the lower adjusting rod 3021 to 5 are in an integrated structure. The female joints 3021 to 8 of the universal joints are respectively connected with the corresponding roller bodies 3021 to 1, and specifically, the universal joints can be connected through bolts and threads, that is, the female joints 3021 to 8 are provided with bolts of an integrated structure, and the bolts are screwed with threaded holes on the roller bodies 3021 to 1. The male joint 3021-7 is articulated to the rotary core by means of a rotary axis along a first plane of rotation, and the female joint 3021-8 is articulated to the rotary core by means of another rotary axis along a second plane of rotation, intersecting the two planes of rotation, preferably perpendicular to each other. Therefore, the roller unit and the telescopic unit are movably connected through the universal joint, and at the moment, the angle between the roller unit and the telescopic unit is adjustable.

Further, a bolt is connected to the end portion, close to the female joint 3021-8 of the universal joint, of the roller body 3021-1 in a threaded manner, and the female joint 3021-8 is in a circumferential rotation fit with the bolt. Specifically, an annular clamping groove is formed in the bolt, a clamping ring matched with the annular clamping groove is arranged on the female joint 3021-8, and the female joint 3021-8 can be rotationally matched with the bolt along the circumferential direction of the axis of the female joint 3021-8 through the rotational matching of the annular clamping groove and the clamping ring.

Example eight:

as shown in fig. 15 to 16, in order to allow the above-mentioned drag chain 3021 to extend along the outer surface of the curved column 100 in a curved manner in the axial direction of the column 100, a guide rail 303 is provided at a position on the column 100 corresponding to each drag chain 3021, the guide rail 303 extends in the axial direction of the column 100, and the drag chain 3021 is fitted on the corresponding guide rail 303 and moves in the longitudinal direction of the guide rail 303 under the guiding action of the guide rail 303.

Specifically, the guide rail 303 comprises two guide rods 3031 which are parallel to each other and suspended on the outer surface of the upright 100, a moving path of the traction chain 3021 is formed between the two parallel guide rods 3031, the traction chain 3021 is arranged between the two guide rods 3031 and is in sliding fit with the two guide rods 3031 along the moving path of the traction chain 3021, or guide wheels 3021-2 on the traction chain 3021 are in rolling fit with the corresponding guide rods 3031 when a roller unit is arranged on the traction chain 3021. For example, the rolling unit on the traction chain 3021 comprises four first guide wheels 3021-2 ' and four second guide wheels 3021-2 ", wherein two first guide wheels 3021-2 ' and two second guide wheels 3021-2" are respectively abutted against the first guide rod and are in rolling engagement along the guide rod 3031, and the other two first guide wheels 3021-2 ' and the other two second guide wheels 3021-2 "are respectively abutted against the other guide rod 3031 and are in rolling engagement along the guide rod 3031. At this time, an inwards concave sliding chute is formed between two guide wheels 3021-2 of the four first guide wheels 3021-2 'facing the first guide rod 3031 and is used for cooperating with the first guide rod 3031 to play a role in moving and guiding, and the other two first guide wheels 3021-2' also form an inwards concave sliding chute, so that the two sliding chutes can be regarded as an "H" -shaped sliding rail, so that the rolling unit can be well limited between the two parallel guide rods 3031, and the separation from the moving path of the traction chain 3021 between the two guide rods 3031 is avoided. The drag chain 3021 with the structure can simplify the structure of the guide rail 303, and after the drag chain 3021 is matched with the guide rail 303, the matching is more stable, so that the risk of the drag chain 3021 being separated from the guide rail 303 is greatly reduced.

Further, in order to avoid that the guide rod 3031 is bent by itself under a force to cause the movable path of the drag chain 3021 to be locally deformed so as to cause the disengagement of a part of the rolling units in the drag chain 3021, a resisting block 3032 is arranged on the other side of any guide rod of the guide rail 303, which is away from the guide wheel 3021-2 of the drag chain 3021, and the supporting force of the resisting block 3032 acting on the guide rod 3031 and the pressure of the guide wheel 3021-2 acting on the guide rod 3031 on the drag chain 3021 are mutually acted as a acting force and a reaction force. Namely, the acting force of the two first guide wheels 3021-2' and the two second guide wheels 3021-2 ″ acting on the guide rod 3031 at the same time and the acting force of the resisting block 3032 acting on the guide rod 3031 are mutually offset, so that the guide rod 3031 is stressed uniformly.

Furthermore, the number of the guide rails 303 is the same as that of the traction chains 3021, all the guide rails 303 are arranged at intervals along the circumferential direction of the upright post 100, each traction chain 3021 is respectively matched with the corresponding guide rail 303, a resisting block 3032 is arranged between any two adjacent guide rails 303, the resisting block 3032 is fixedly connected with the upright post 100 through bolts, and two end surfaces of the resisting block 3032, which correspond to the two adjacent left and right guide rails 303, are both concave inwards to form arc-shaped end surfaces matched with the guide rods 3031.

The rotational connection means that the angle between the two parts is adjustable so as to achieve a rotational fit, for example a fit between a ball bearing and a ball stud. One end of each of the two second leveling springs 3023-2 is fixedly connected to the support ring 2012, for example, the other end of each of the two second leveling springs 3023-2 is fixedly connected to the corresponding drag chain 3021 of the adjustable connection piece 3023 by using a hook and a hanging hole.

Of course, the adjusting rod 3023-1 may also be a hydraulic rod or other type of conventional telescopic rod.

Specifically, an anchor ear 3023-3 is sleeved outside an adjusting sleeve 3021-6 in a telescopic unit of the drag chain 3021, the anchor ear 3023-3 is fixedly connected with the adjusting sleeve 3021-6, a universal joint is mounted on the anchor ear 3023-3, and the upper end of the adjusting pull rod 3023-1 is movably connected with the universal joint.

Example ten:

as shown in fig. 17 and 18, when the uppermost blade 201 is a movable blade 201-S on the column 100, the uppermost movable blade 201-S is installed, and the movable blade 201-S can not only be lifted and lowered along with the movement of the drag chain 3021, but also the angle of the movable blade 201-S can be adjusted until the movable blade 201-S can be in a horizontal state when it is at least in one position during the movement along with the drag chain 3021.

Therefore, the uppermost movable blade 201-S needs to be connected to the drag chain 3021 through a connection mechanism of a specific structure.

Specifically, a reference support rod 3024 and two adjustable support rods 3025 are disposed between the movable blade 201-S at the uppermost layer and the column 100, the lower end of the reference support rod 3024 is fixedly connected to the corresponding drag chain 3021 through a lower connecting piece 3026, the upper end of the reference support rod 3024 is movably connected to an upper connecting piece 3027 through a universal joint, which is also referred to as a rotary connection, and the upper connecting piece 3027 is fixedly connected to the support ring 2012 of the movable blade 201-S at the uppermost layer.

Of course, to achieve the height adjustment of the connection position between the adjustable support rod 3025 and the lower connecting piece 3026 along the vertical direction, various conventional techniques in the prior art may be adopted, and therefore, the details are not described herein.

Example eleven:

the basic structure is the same as the above embodiment except that: as shown in fig. 4, 3q drag chains 3021 are arranged on the outer periphery of the column 100 along the circumferential direction, wherein q is an integer greater than or equal to 1, and the movable blades 201-S with the same movement stroke and the same movement direction on the column 100 can be installed on the same 3 drag chains 3021. Taking 45 blades 201 on the curved upright post 100 as an example, all the blades 201 are divided into 9 blade groups, any blade group comprises 1 reference blade 201-0 located at the middle position, 2 movable blades 201-S located above the reference blade 201-0 and 2 movable blades 201-S located below the reference blade 201-0, and when the blades 201 in the blade group are required to be gathered to be in a flower shape, 2 movable blades 201-S located above the reference blade 201-0 in 4 movable blades 201-S in a single blade group move downwards to be close to the reference blade 201-0, and 2 movable blades 201-S located below the reference blade 201-0 move upwards to be close to the reference blade 201-0. In addition, the moving strokes of the 2 moving blades 201-S above the reference blade 201-0 towards the reference blade 201-0 are different, and the moving strokes of the 2 moving blades 201-S below the reference blade 201-0 towards the reference blade 201-0 are also different, so that each moving blade 201-S in the 4 moving blades 201-S needs to be connected with a respective drag chain 3021 through 3 connecting points, and therefore the 4 moving blades 201-S need to complete the axial driving of the moving blade 201-S through 12 drag chains 3021. Of course, each movable blade 201-S in the 9 blade sets can be correspondingly connected to the corresponding drag chain 3021, so that all the movable blades 201-S on the single upright post 100 can realize the initial state that the 9 blade sets are unfolded to be parallel to each other or are gathered to be in a state of 9 flowers by pulling the 12 drag chains 3021.

Example twelve:

the basic structure is the same as in example eleven, except that: taking 5 blades as an example to form a blade group, the blade 201 at the middle position is a reference blade 201-0, and sequentially comprises an upper two movable blades 201-S2, an upper one movable blade 201-S1, a reference blade 201-0, a lower one movable blade 201-S3 and a lower two movable blade 201-S4 from top to bottom, wherein the upper one movable blade 201-S1 and the lower one movable blade 201-S3 are symmetrically designed along the reference blade 201-0, and the upper two movable blades 201-S2 and the lower two movable blades 201-S4 are also symmetrically designed along the reference blade 201-0. Therefore, the path lengths of the movement of the last movable blade 201-S1 and the next movable blade 201-S3 toward the reference blade 201-0 at the middle position are the same, and the path lengths of the movement of the last movable blade 201-S2 and the next movable blade 201-S4 toward the reference blade 201-0 at the middle position are also the same. Therefore, the moving paths of the drag chain 3021 moving the previous movable blade 201 to S1 and the drag chain 3021 moving the next movable blade 201 to S3 are the same, except that one of the drag chains 3021 moves downward and the other moves upward. Based on the requirement, the upper ends of the two drag chains 3021 corresponding to the previous movable blade 201-S1 and the next movable blade 201-S3 are connected with each other to form an integral drag chain 3021, and the upper end of the drag chain 3021 is reversed through the fixed pulley 304 arranged at the top end of the upright 100, so that the problem that one section of the drag chain 3021 is lifted and the other section is lowered can be well solved. Similarly, the moving paths of the drag chain 3021 driving the upper two movable blades 201 to S2 to move and the drag chain 3021 driving the lower two movable blades 201 to S4 to move are the same, and based on this requirement, the upper ends of the two drag chains 3021 corresponding to the upper two movable blades 201 to S2 and the lower two movable blades 201 to S4 are connected to each other to form an integral drag chain 3021, and the upper end of the drag chain 3021 is reversed by the fixed pulley 304 installed at the top end of the upright post 100, so that it can be well solved that one section of the drag chain 3021 is lifted and the other section is lowered. Therefore, only two traction chains 3021 are needed in a blade group consisting of 4 movable blades 201-S and a reference blade 201-0 to drive the 4 movable blades 201-S to move up and down, the number of driving parts for driving the traction chains 3021 to move is greatly reduced, the overall structure is simplified, and meanwhile, the whole traction chain 3021 realizes the annular shape through the fixed pulley 304, so that the ascending distance and the descending distance of the traction chain 3021 are consistent, and the control difficulty is reduced.

Taking 4 movable blades 201-S as an example, each movable blade 201-S needs 3 drag chains 3021 to realize positioning installation, and a total of 12 drag chains 3021 are needed, and the ascending drag chain 3021 and the descending drag chain 3021 with the same stroke can be connected with each other to form a whole, so that the 12 drag chains 3021 can be simplified into 6 drag chains 3021.

Further, as a preference, when the upper ends of the two drag chains 3021 are connected to each other to perform a reversing operation around the fixed sheave 304, the lower ends of the two drag chains 3021 may also be connected to each other, so that the drag chains 3021 are endless drag chains 3021 connected end to end. 4 moving blades 201-S on 1 blade set correspondingly require 6 endless drag chains 3021, and the 45 blades on the upright post 100 can be divided into 9 blade groups, each blade group can be respectively connected with a respective annular drag chain 3021, thereby, the whole upright 100 has 9 blade groups, but only needs 6 annular drag chains 3021, thereby, the number of the drag chains 3021 can be greatly reduced, and the number of the movable blades 201-S in the blade group can be increased or decreased, or the path length of the movement of the different moving blades 201-S in the blade assembly is divided into a plurality of different lengths, which will cause a corresponding change in the number of drag chains 3021, which can be based on the number of moving blades 201-S in a single blade assembly, the moving blades 201-S being grouped into several stroke lengths, and whether the motion profile of each movable blade 201-S is the same between each blade group to calculate the number of corresponding drag chains 3021. The number of drag chains 3021 can thus be calculated simply on the basis of the actual requirements, and is therefore not given as an example.

Preferably, the closed-loop drag chain 3021 is located at the position of the blade 201, which requires the roller unit and the telescopic unit of the drag chain 3021 to be used for pulling on the curved upright, but it should be understood that the whole of the closed-loop drag chain 3021 including but not limited to the roller unit and the telescopic unit is composed of the roller unit and the telescopic unit, and the closed-loop drag chain 3021 can be connected by the conventional chain 3030 for the sake of cost and connection strength when there is no local guiding requirement for the drag chain, so as to reduce the number of the roller unit and the telescopic unit, i.e., the whole drag chain 3021 should be understood as being composed of a plurality of segments which are spliced end to end, and one or more segments of the drag chain 3021 can be composed of the roller unit and the telescopic unit in an alternating structure, and the rest can be connected.
