[0002] With the rapid development of modern industry, many applications have been implemented in the field of sports architecture in combination with existing scientific and technological technologies.

[0003] For example: CN217760282U, a new type of lifting stand for sports buildings. The utility model relates to the technical field of lifting stands, and in particular to a new type of lifting stand for sports buildings. Its technical solution includes: a base, a hydraulic top, a support frame, a hinge, a fixed platform, a spring and an inflatable slide. Support frames are welded on both sides of the top of the base. Three fixed grooves are opened in a straight line and equidistantly on the top of the base on the opposite side of the two support frames. The bottoms of the three hydraulic tops are inserted into the three fixed grooves respectively. Slides are opened on the opposite sides of the two support frames. Inflatable slides are stored inside the fixed platform. Slides are welded on both sides of the fixed platform. The ends of the two slides that are separated from each other are respectively rotatably installed with pulleys, and springs are installed inside the two slides. The utility model has the advantages of good security that when the lifting stand fails, the audience can use the inflatable slide to escape. The lifting stand for sports buildings described in the utility model has a relatively single function and is inconvenient to move, so it can only be used as a static device.

[0037] The present invention provides a multifunctional lifting platform for sports building space, and its working principle is as follows: the device can meet the needs of multiple scenes of use in the interior and exterior spaces of sports buildings. When not in use, it is in a rectangular static platform state, and can be used as a podium or a platform-type device with other functions. If it is necessary to transfer the venue, several groups of landing wheel groups 2 in the device are started at the same time. When the landing wheel groups 2 are started, the hydraulic push rod E205 is started, and when the push rod is pushed outward, it drives the connecting arm A207 to rotate along the support plate B202 and the support plate C203 through the ball head shaft B206. When the connecting arm A207 rotates, it drives the connecting arm D212 to rotate along the support plate B202 through the connecting arm C211. When the connecting arm A207 rotates, it drives the connecting arm D212 to rotate along the support plate B202 through the fork rod A208. The movable connecting arm B209 rotates along the ball head axis C210. ​​When the connecting arm A207 rotates, the wheel group 218 is driven to rotate through the connecting arm E217. When the connecting arm A207 rotates, the fork rod B213 is also driven to rotate through the fork rod A208. The fork rod B213 drives the connecting piece 215 to push the ball head axis E216 through the ball head axis D214. The ball head axis E216 pushes the connecting arm E217 to rotate along the connecting arm A207. At this time, the connecting arms A207 and E217 of the landing wheel group 2 are fully unfolded, and the wheel group 218 hidden inside is unfolded and supported on the ground. When all the landing wheel groups 2 in the device are fully unfolded, the device is fully supported, so that the device has a mobile function, which is convenient for rapid transfer to different venues. Of course The function of the wheel set 218 can also be adjusted according to actual conditions, for example, it can be adjusted to a motor wheel or a universal wheel, etc. After the device is moved to the required coordinates, the wheel set 218 in all the landing wheel sets 2 are reset according to the above method. At this time, the device is supported on the ground by the bottom plate 107 in the frame assembly 1. The device also has a step function. When the device is required to form a platform with different height differences, the hydraulic push rods A108, B110, C112, and D114 are started synchronously. The four groups of hydraulic push rods push the three groups of seat devices 3 upward simultaneously through the connecting seats A109, B111, C113, and D115, wherein the seat devices 3 are lifted upward through the support plate D3 01. The positioning axis at the bottom of the outer enclosure plate B303 slides along the through hole reserved in the frame C106 to ensure that the three groups of seat devices 3 move upward smoothly and safely. When the hydraulic push rods A108, hydraulic push rod B110, hydraulic push rod C112, and hydraulic push rod D114 are pushed to the required height and then stop running. At this time, the entire equipment is in a stepped shape, which enriches the use needs of collective people in sports buildings. This equipment can also be used as a temporary auditorium. First, open the corresponding backrest device 4 in each group of seat devices 3. The operation is simple and convenient. Place both hands on the lower end of the backboard bracket 411 and lift it up. At this time, the backboard bracket 411 drives the bracket E407 and the bracket I410 to rotate along the bracket B404 and the bracket A403 respectively.When bracket E407 rotates, bracket B404 is driven to rotate along bracket B404 through bracket D406. When bracket I410 rotates, bracket F408 is driven to rotate along bracket A403 through bracket G409. When the backboard bracket 411 is fully opened, the backboard bracket 411 and the seat board 401 are at an obtuse angle, which is convenient for human body to lean on. Each set of seat devices 3 can seat four people. In order to facilitate outdoor work, a structure for facilitating drainage of the seat device 3 is also provided here. Four sets of water discharge plates 402 are embedded in the seat board 401. When the backrest device 4 is in the open state and it rains suddenly, in order to avoid water accumulation in the seat board 401, the accumulated water in the seat board 401 will flow down through the water discharge plate 402 through the water tank 311 and merge into the water guide tank A. 102, and then discharged outwardly through the drainage hole reserved in the outer guard plate 118, while the water accumulated in the seat plate 401 of the lifting seat device 3 will flow down through the lower water trough 311 through the lower water plate 402 and flow into the water guide trough B117, and then be discharged outwardly through the water outlets at both ends of the water guide trough B117. Considering that the traditional seats cannot be divided into corresponding groups for people of different age groups and different heights, the present device provides a device for lifting the seat device 3 here, the main purpose of which is to divide people of different heights so that people of each height range have no visual obstruction. When a group of seat devices 3 needs to be lifted, the motor A321 is started, and its output shaft rotates to drive the pulley A322 to rotate, and the pulley A322 is driven by the belt 3 23 drives pulley B324 to rotate, pulley B324 drives screw shaft 325 to rotate, screw shaft 325 drives screw block 327 to move linearly along screw shaft 325, when screw block 327 moves, it drives slider seat C328 to slide along guide rail E329 and guide rail F330, when slider seat C328 moves, it drives connecting rod A332 to rotate through shaft seat B331, connecting rod A332 drives connecting rod B334 to rotate along shaft seat C335 through axle 336, when connecting rod A332 and connecting rod B334 rotate synchronously, they drive connecting block A333 and axle 336 to move upward, the pulleys on both sides of axle 336 slide along the grooves inside pulley connecting block A337 and pulley connecting block B338, and the sliding also drives the pulleys The connection block A337 and the pulley connection block B338 move upward, and the pulley connection block A337 and the pulley connection block B338 drive the support plate E310 to move upward. When the support plate E310 moves, it drives the slider seat A306 to slide along the guide rails A304 and B305. When the support plate E310 moves, it drives the slider seat B309 to slide along the guide rails C307 and D308.
