The viewing angle changing device utilizes combination of linear push-and-pull movement of the push-and-pull mechanism and rotation movement driven by the lifting mechanism to realize lifting of the box type steps. The viewing angle changing device is simple and stable in structure, convenient in operation and flexible in angle and height adjustment, and the box type steps can guide each other. The curved swinging frame is engaged with roller wheels arranged on lower portions of chairs to move relatively so as to realize stable lifting and change of angles. The viewing angle changing device of a fixed grandstand is wide in application range without limitation of occasions and activity contents, and then has extremely wide application prospect and market prospect.
Description
Technical field
The utility model relates to a kind of grandstand arrangement for adjusting height, specifically a kind of fixedly grandstand view transformation device.
Background technology
At present, various sports tournaments or recreation performance become requisite leisure project in people's life gradually, and the stadiums number of nation-building increases gradually.The grandstand of existing all kinds of stadiums or public place of entertainment is the fixed structure grandstand, and this type of grandstand is not removable, can't lifting regulating visual angle etc., so the best angle that spectators come to matches is difficult to satisfy, and directly influences viewing effect.Spectators' viewing angle is not good will inevitably to stand or jump, make watch disorder, bad management.Fixedly the setting of grandstand has also limited movable content to a great extent, can only limit within the specific limits and carry out, and can not suitably regulate according to the scale or the content of performance or match, is unfavorable for making full use of of movable venue.
At the problems referred to above, those skilled in the art have proposed a kind of detachable grandstand, promptly are made up of each bridge piece, overlap according to concrete needs during use and adjust the height angle, and this design can effectively remedy the fixedly deficiency of grandstand.But the bridging arrangement complexity all must take a long time assembling when using at every turn, after the use, also needs to spend the certain hour dismounting, causes the inconvenience in the use.And this structure has very high requirement to technician's technical level, consummate degree, if the assembling of a certain link not to or not in place, dangerous situation such as all may cause that grandstand caves in.And the parts that disassemble are too much, storage inconvenience no the time, and also maintenance bothers especially.
In sum, it is flexible and changeable to be badly in need of a kind of height at present, can adapt to the table apparatus of seeing of different places and environmental requirement.
The utility model content
The purpose of this utility model provides a kind ofly can adjust grandstand height, fixedly stand seat view transformation device simple in structure arbitrarily.
For achieving the above object, the utility model is taked following technical scheme:
Fixing grandstand view transformation device, described device comprises a fixed mount, and this fixed mount top is provided with push-pull mechanism, and described push-pull mechanism connects the swing span upper end, and this swing span can be swung in certain angle around connecting axle; Described swing span support has box step, and the orlop step connects elevating mechanism, and the swing span lower end is provided with big roller, and this big roller moves in the guide rail of orlop step.
Above-mentioned fixedly grandstand view transformation device wherein, also comprises lead, and this lead is arranged at orlop step two ends, is connected with this step.
Above-mentioned fixedly grandstand view transformation device, wherein, described box step is made up of seat and casing.
Above-mentioned fixedly grandstand view transformation device, wherein, described box step bottom is provided with roller.
Above-mentioned fixedly grandstand view transformation device, wherein, described swing span is the curved surface swing span.
Above-mentioned fixedly grandstand view transformation device, wherein, described push-pull mechanism is made up of electric pushrod.Described elevating mechanism is made up of scissors mechanism and motor reducer.
Advantage of the present utility model and beneficial effect are:
Straight line push-and-pull campaign and the combination that rotatablely moves under elevating mechanism drives that the utility model utilizes push-pull mechanism realize the lifting of box step.The utility model simple and stable structure, easy to operate, angle and Height Adjustment are flexible, and box step can lead each other.The roller that curved surface swing span and box step bottom are provided with cooperates the realization stable elevation that relatively moves, and realizes the variation at visual angle.The utility model has wide range of applications, and is not subjected to the restriction of place and activity description, therefore has very wide application prospect and market prospects.
Above the utility model content part has been done sufficient explanation to the utility model, below in conjunction with the drawings and specific embodiments the utility model is described in further details, present embodiment only is the utility model preferred forms, is not to qualification of the present utility model.
Description of drawings
Fig. 1 falls the status architecture schematic diagram for the utility model;
Fig. 2 is the utility model intermediateness structural representation;
Fig. 3 rises view for the utility model;
Fig. 4 is the utility model vertical view.
The specific embodiment
As Fig. 1,2,3 and shown in Figure 4, fixing grandstand view transformation device, described device comprises a fixed mount 1, and this fixed mount 1 top is provided with push-pull mechanism 2, and described push-pull mechanism 2 connects swing spans 3 upper ends, and this swing span 3 can rotate in certain angle around connecting axle; Described swing span 3 supports have box step 4, and the orlop step connects elevating mechanism 5, and swing span 3 front portions are provided with big roller 31, and this big roller 31 moves in the guide rail 41 of orlop step.Also comprise lead 6, this lead 6 is arranged at orlop step two ends, is connected with this step.Described box step 4 is made up of seat 42 and casing 43, and box step 4 bottoms are provided with roller 44.Swing span 3 is the curved surface swing span.Push-pull mechanism 2 is formed (not shown in the figures, as to be known technology) by electric pushrod.
When the utility model specifically uses, fixing grandstand view transformation device can be provided with around the place, concrete quantity is determined according to actual conditions, before and after the grandstand view transformation device (before spectators' direction of visual lines is, down together) width dimensions is recommended as 5869*7270 (1), 4856*7244 (part about 2 slices-minute), 6865*9938 (symmetrical structure in the present embodiment, each 2, totally 4).
The state of falling does not need lifting, and the rise state needs by the combination that rotatablely moves under the rectilinear motion of push-pull mechanism and the elevating mechanism drive.Other has intermediateness, is to finish the intermediateness (non-final required state) that produces behind the componental movement.
11 box steps fall to being placed on initial bit on the fixed mount, are Fig. 1 and fall state.Push-pull mechanism mainly is made up of electric pushrod, and elevating mechanism mainly is made up of scissors mechanism and motor reducer.Push-pull mechanism is positioned at fixed mount top, and under the promotion of push-pull mechanism, the position of 11 steps converts Fig. 2 position to by Fig. 1 position, and rectilinear path is about 490mm.Be positioned at orlop step rising 1595mm under the effect of elevating mechanism, swing span is the central axis swing with the center of rotation of push-pull mechanism front portion, and all the other box steps finally reach Fig. 3 and rise state rising under by curved surface and roller relative motion on the swing span.
The big roller that is positioned at the swing span front portion is the guide rail moving linearly of first step forwardly.11 box-shaped steps can lead each other.The process of falling is identical with above-mentioned rise Principle of Process, and action is opposite.
