Description

A stepped stage with self-adaptive height adjustment

technical field

The utility model relates to a step stage with self-adaptive height adjustment.

Background technique

In stage performances, especially choral performances, it is often necessary to use a stepped stage so that more actors can be arranged in steps. Existing stepped stages generally have fixed heights, but the heights of actors are uneven. If the heights of actors standing on the same stepped stage are not uniform, the stage effect will be affected.

Utility model content

The purpose of the utility model is to provide a step stage with self-adaptive height adjustment.

In order to achieve the above purpose, the following technical solution is adopted: an adaptive height-adjustable step stage, characterized in that: the step stage includes a platform, the bottom of the platform has a base, and the platform and the base are connected by two symmetrically arranged telescopic frame connection; the base is provided with a cylinder, and the output shaft of the cylinder is aligned vertically upwards and connected to the bottom of the platform; a cylinder reversing valve is also provided on the side above the platform, and the air intake control end of the cylinder reversing valve is connected to the air intake of the cylinder. The air outlet control end of the cylinder reversing valve is connected with the air outlet of the cylinder; the four corners under the base are connected to the support rod through spring hinges, and the bottom of the support rod is fixedly connected with a screw sleeve; the screw sleeve is also connected with an adsorption device; The adsorption device includes a suction cup, and the top of the suction cup is fixedly connected with bolts.

The telescopic frame is formed by cross-connecting multiple hinges and multiple supporting steel sheets.

The cylinder model is SDA40-100.

The model of the cylinder reversing valve is 4H210-08.

The utility model designs the stair stage into a modular structure, each actor can use a stair stage independently, and adjust the height of the stair stage according to his standing position and height, so that all the actors can maintain a good posture after standing. The hierarchical queue and the height of each level are unified; its design principle is simple, and it is easy to store and assemble, and has strong practicability.

detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.

As shown in Figures 1 to 4, an adaptive height-adjustable stepped stage includes a platform 1 with a base 2 at the bottom of the platform 1, and the platform 1 and the base 2 are connected by two symmetrically arranged telescopic frames 3; The base 2 is provided with a cylinder 4, the output shaft of the cylinder 4 is aligned vertically upwards and connected to the bottom of the platform 1; the upper side of the platform 1 is also provided with a cylinder reversing valve 5, and the air intake control end of the cylinder reversing valve 5 is connected to the cylinder The air inlet of 4 is connected, and the air outlet control end of the cylinder reversing valve 5 is connected with the air outlet of the cylinder 4; the four corners below the base 2 are connected to the support rod 8 by the spring hinge 7, and the bottom of the support rod 8 is fixedly connected with a screw sleeve 9; An adsorption device 10 is also connected to the screw sleeve 9; the adsorption device 10 includes a suction cup 101, and a bolt 102 is fixedly connected to the top of the suction cup 101.

The telescopic frame 3 is formed by cross-connecting a plurality of hinges 301 and a plurality of supporting steel sheets 302 .

The model of the cylinder 4 is SDA40-100.

The model of the cylinder reversing valve 5 is 4H210-08.

When in use, firstly, according to the needs of the performance, the multiple step stages are placed on the stage according to levels, and each step stage corresponds to a performer. Next, adjust the height of the stepped stage according to the level of the stepped stage and the height of the performers. There are two ways to adjust the height. One is to adjust the connection depth when the bolt on the adsorption device at the bottom of the step stage is connected to the screw sleeve, so as to realize the purpose of raising or lowering the entire step stage. The maximum adjustment height can be It is determined by the length of the threaded connection between the bolt and the threaded sleeve. The adjustment of the connection depth between the bolt and the threaded sleeve is fine-tuning, which can achieve a relatively ideal accuracy; the other is that the performer can control the work of the cylinder by operating the cylinder reversing valve. The output shaft of the cylinder drives the platform to rise or fall to achieve the purpose of raising or lowering the platform. The maximum height of its adjustment can be determined by the maximum pulling length of the telescopic frame and the output shaft of the cylinder, and this adjustment is a coarse adjustment, which can be adjusted The height is controlled within a relatively reasonable range. The above-mentioned adjustment operations are all adjusted by the performer according to the level of the stepped stage and his own height, so as to ensure that the people standing on the stepped stage rise step by step, and at the same time ensure that the people on the stepped stage on the same floor Keep the height consistent.

When the performance is over, the output shaft of the cylinder can be controlled to retract to the shortest position through the cylinder reversing valve, and then the platform and the base can be compressed to the closest distance through the telescopic frame; at the same time, the adsorption device is removed, and the support rod Pivot around the spring hinge until it is level with the bottom of the base. In this way, the step stage can be compressed to the minimum size, which is convenient for storage and storage.

The utility model designs the step stage into a modular structure, each actor can use a step stage independently, and adjust the height of the step stage according to the position and height of the stand, so that all actors can maintain a good level after standing The queue and each level are highly unified; its design principle is simple, easy to store and assemble, and has strong practicability.
