[0024] In order to make the technical means, creative features, objectives and effects of the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1-Figure 5 As shown, an armrest for an earthquake simulation device includes a gripping portion 1, an adjusting portion 3, and a mounting portion.

[0027] The mounting part includes two columns 2. The columns 2 are mounted on the demonstration platform of the earthquake simulation device. The gripping part 1 can be mounted on the top of the columns 2 through the adjusting part 3. The height of the gripping part 1 can be adjusted. The adjusting part 3 can also lock the angle between the gripping part 1 and the mounting part.

[0028] The gripping part 1 comprises a C-shaped column, wherein the long end of the C-shaped column is the main gripping part, and the experiencer mainly grips the long end. The two end points of the gripping part 1 extend inwardly and are connected to the mounting part through the adjusting part 3.

[0029] The adjusting part 3 includes a rotating part, a base, and a locking structure, wherein the rotating part is composed of a stop plate 301, which is arranged at both ends of the C-shape of the gripping part 1; the base is composed of a lower plate shell 302, which is arranged at the top of the mounting part; the locking structure is composed of a slider 303, a fixing pin 304, and a connecting plate.

[0030] The bottom of the column 2 is arranged on the demonstration platform of the earthquake simulation device, and a fixing flange 4 is arranged at the bottom of the column 2 , and the column 2 is fixed to the demonstration platform of the earthquake simulation demonstration device through the fixing flange 4 .

[0031] The fixing flange 4 is circular in shape, with a diameter larger than that of the column 2. A reinforcing rib is provided at the connection between the fixing flange 4 and the column 2, and a screw hole is provided near the reinforcing rib to assist the connection between the fixing flange 4 and the demonstration platform through bolts. The reinforcing rib can resist loads from different directions on the column.

[0032] The structure of the column 2 is that it extends upward from the demonstration platform in the vertical direction for a distance, then gradually bends 90 degrees after a distance, extends to the outside of the demonstration platform, extends horizontally for a distance, then bends upward 90 degrees and is provided with a lower plate shell 302. The structure of the gripping portion 101 is C-shaped, and both ends of the C-shaped are provided with anti-rotation plates 301. The lower plate shell 302 is connected to the anti-rotation plate 301.

[0033] The adjustment part 3 installed at one end point of the gripping part 1 is: a stopper 301. The stopper 301 has two pieces. The stopper 201 is in the shape of a quarter cylinder. The center of the stopper 201 is provided with a hole for accommodating the gripping part 1. The stopper 201 is provided with three fixing holes 306 for accommodating the fixing pins 304 away from the center. A portion of the top of the gripping part 1 passes through the hole at the center of a stopper 301 and is fixed by welding; the second stopper 301 can be set at the top of the gripping part 1, fixedly connected by bolts, and can be disassembled. The position between the gripping part 1 and the first stopper 301 does not change, and the position of the outer stopper 301 with the gripping part 1 does not change after being fixed by bolts.

[0034] The adjustment part 3 disposed on the top of the column 2 has a lower shell 302. The lower shell 302 is a metal block extending upward in the vertical direction, and the surface of the metal block is provided with an adjustment structure mounting hole capable of accommodating the gripping part 1, a fixing pin mounting hole accommodating the locking structure, and a locking structure adjustment hole. The lower shell 302 and the column 2 are integrally formed.

[0035] The gripping part 1 is connected to the column 2 via the adjusting part 3. The gripping part 1 releases the outer anti-rotation piece 301, passes through the adjustment structure mounting hole above the lower plate shell 302, and then installs the outer anti-rotation piece 301. The gripping part 1 is installed above the column 2 and fixed by two anti-rotation pieces 301, so that the gripping part 1 can rotate on the column 10 without deviation.

[0036] The locking structure of the adjustment part 3 is arranged at the connection between the gripping part 1 and the column 2, so as to fix or release the angle between the gripping part 1 and the column 2.

[0037] The locking structure of the adjustment part 3 includes a slider 303, a fixing pin 304, and a connecting plate. The anti-rotation plate 301 is provided with three fixing holes 306; the lower plate shell 302 is provided with a hole 1 for accommodating the gripping part 1 and a fixing pin mounting hole and a locking structure adjustment hole for accommodating the locking structure. The fixing pin mounting hole is arranged at the middle end of the lower plate shell 302, and the locking structure adjustment hole is arranged at the bottom end of the lower plate shell 302. The slider 301 passes through the lower plate shell through the locking structure adjustment hole at the bottom of the lower plate shell 302. One end of the slider 303 is connected to the fixing pin 304 through a fixing plate.

[0038] The anti-rotation plate has three fixing holes 306 for accommodating the fixing pin 304, and the heights of the handrails corresponding to the three holes are 1200mm, 950mm, and 610mm. The fixing pin 304 can pass through the fixing hole 306 on the anti-rotation plate 201 and the fixing pin installation hole at the middle end of the lower plate shell 302 to fix the gripping part 1 to the column 2. After fixation, the angle between the gripping part 1 and the column 2 does not change.

[0039] A connecting plate is arranged on the top of the fixing pin 304, and a slider 303 is arranged on the other end of the connecting plate. The positions among the connecting plate, the slider 303 and the fixing pin 304 do not change.

[0040] The slider 303 is arranged at the locking structure adjustment hole at the bottom end of the lower plate housing 302. The slider 303 passes through the locking structure adjustment hole. By controlling the slider 303, the connecting plate can be driven to control the fixing pin 304. The fixing pin 304 can lock or unlock the angle between the gripping portion 1 and the column 2. A spring is arranged inside the slider 303, and the spring can ensure that the slider 303 remains locked when no external force is applied.

[0041] When the angle between the gripping part 1 and the column 2 needs to be changed, the locking of the fixing pin 304 is released. The slider 301 is pulled out, and the slider 301 releases the fixing pin 304 through the fixing plate. At this time, the angle between the gripping part 1 and the column 2 can be adjusted. The angle between the gripping part 101 and the column 2 is adjusted, and the slider 301 is locked. The slider 301 is fixed in the lower plate housing 302 by a spring. During the locking process, the slider 301 controls the connection between the fixing pin 304 and the anti-rotation plate 201 through the fixing plate, and locks the angle between the gripping part 1 and the column 2.

[0042] Before the earthquake simulation device is used, the gripping part 1 of the device can adjust the angle, and the adjusting part 3 releases the lock between the gripping part 1 and the column 2. The gripping part 1 is adjusted to the outside of the demonstration platform. This allows the experiencer to have a larger space when entering and exiting the device, avoiding collision between the experiencer and the earthquake simulation device.

[0043] Before the earthquake simulation device moves, the height of the gripping part 1 is determined according to the practical height of the experiencer, and is locked using the adjusting part 3. This ensures that the handrail can be gripped in accordance with the experiencer's posture when simulating an earthquake.

[0044] When the earthquake simulation device is in operation, the demonstration platform will shake to a certain extent when simulating an earthquake. The experiencer can feel the shaking caused by the earthquake and can use the handrails to maintain his body balance to ensure the safety of the experiencer.
