Description

Technical Field

[0001] The utility model discloses a lifting platform, belonging to the technical field of lifting platforms, in particular to a novel lifting platform for radio measurement experiments. Background Art

[0002] The experimental lifting platform is generally composed of an upper panel, a lower panel, a rotating shaft and a hand wheel. It is mainly used to place relevant experimental equipment in the laboratory and adjust the height of objects. The biggest difference from the engineering lifting platform is that it is smaller in size, and the lifting range is mostly around 42-150 mm. The upper and lower panels are usually squares with a side length of 10 cm. In radio measurement experiments, experimenters usually use this type of small lifting platform to place various cables, adapters and certain devices to be measured to overcome the measurement error caused by the loose interface caused by the height difference between the test equipment and the device under test.

[0003] The patent document with the prior art publication number CN218543753U provides a new type of lifting platform for radio metrology experiments, including an electromagnetic shielding box for radio metrology experiments and a switching device installed in the electromagnetic shielding box, and also includes a lifting component installed under the electromagnetic shielding box for driving it to be lifted and lowered smoothly. The lifting component includes: a base plate and a lifting plate, and an adjustment component installed between the base plate and the lifting plate for adjusting the distance between the lifting plate and the base plate. When the utility model needs to drive it to rise, the transmission threaded rod is driven to rotate by a control motor, and the L-shaped moving frame is driven to move along the guide rod through the threaded connection between the transmission threaded rod and the L-shaped moving frame, and the L-shaped moving frame moves to the right through the L-shaped moving frame, driving the hinged rod two to lift the lifting plate, and cooperating with the hinged rod one to support the lifting plate, so that its lifting is more stable.

[0004] However, when using the existing lifting platform for radio metrology experiments, after the experimenter places the experimental items that need to be measured on the lifting platform, the placement of the experimental items may deviate after the lifting platform rises, which affects the experimental measurement error and requires moving the entire lifting platform to adjust the experimental items. Utility Model Content

[0014] (III) Beneficial effects

[0015] The utility model provides a new type of lifting platform for radio measurement experiments, which has the following beneficial effects:

[0016] (1) This new type of lifting platform for radio metrology experiments has a placement plate, latch, gear and rotating shaft. When using the lifting platform, the experimenter places the object to be tested on the placement plate, and then operates the motor to drive the threaded shaft to rotate and pull the connecting rod inward. At this time, the hinged plate will also start to move to make the lifting platform rise. When the experimental object reaches the specified position, the experimenter stops the motor. When the experiment is completed, the experimenter operates the motor to drive the threaded shaft to rotate in the opposite direction and push the connecting rod outward. At this time, the hinged plate will also start to move to make the lifting platform descend. When it descends to the point where the experimenter can unload it, the experimenter stops the motor and unloads the experimental item. During the experiment, the latch is turned clockwise to disengage the gear. The placement plate can be rotated to drive the shaft to rotate, and the gear will also rotate with the shaft. After adjusting the direction of the experimental item, the latch is rotated counterclockwise and inserted to fix the gear. This allows the experimental item to be in the direction required for the experiment, so that the impact of experimental errors caused by external influences can be ignored. In addition, the direction of the experimental item can be adjusted at any time during the experiment so that the experimenter can better observe the measurement process of the experimental item.
