The invention discloses a gas-liquid cylinder which comprises a cylinder body, a piston is arranged in the cylinder body, a piston rod with the end extending out of the cylinder body is connected to the piston, a gas chamber and an oil chamber are correspondingly formed in the two sides of the piston in the cylinder body respectively, a gas channel communicated with the gas chamber is formed in the cylinder body, and the oil chamber is communicated with the gas channel. The cylinder body is further provided with an independent oil inlet and an independent oil outlet which are communicated with the oil chamber, and a switch valve is arranged at the oil outlet. When the piston rod extends outwards, the switching valve is closed to close the oil outlet, hydraulic oil is input into the oil chamber from the oil inlet, and gas in the gas chamber is compressed to form pre-pressure; and when the piston rod resets, the switching valve is opened to open the oil outlet, and the hydraulic oil in the oil chamber is discharged from the oil outlet. The reset mechanism has the advantages of being reasonable in structure and high in reset speed.

The utility model discloses a switch cabinet internal multi -freedom degree holder camera device belongs to switch cabinet technical field, including rotating mechanism, rotating mechanism is connected on the cabinet door of switch cabinet through mounting bracket, be provided with multi -freedom degree holder mechanism on rotating mechanism, be provided with camera on multi -freedom degree holder mechanism. The utility model installs rotating mechanism and multi -freedom degree holder mechanism in the cabinet door of switch cabinet, installs the camera on multi -freedom degree holder mechanism, can drive the camera to carry out multi -angle all -round shooting through rotating mechanism and multi -freedom degree holder mechanism, can make the on -duty personnel of monitoring room remote observation in the specific situation in switch cabinet ontology, can observe whether the inside component and the connecting position of electric switch have the trace of burning if there is when the electric switch appears the tripping condition, if not, can adopt the reset mechanism to reset the blade of electric switch, and the reset speed is faster, and it is more convenient to use.

The invention belongs to the technical field of rotor unmanned aerial vehicles, and particularly relates to a vertical take-off and landing fixed-wing unmanned aerial vehicle rotor propeller locking device which comprises a mounting plate, a rotor motor and a rotor propeller which are arranged on a vehicle body. The rotor motors are connected with the rotor propellers through height adjusting mechanisms, and the height adjusting mechanisms are used for adjusting the heights of the rotor propellers when the rotor motors are in a start-stop state; by arranging the height adjusting mechanism, when the starting state and the stopping state of the rotor propellers are converted, the heights of the rotor propellers are adjusted through lift force changes caused by rotating speed changes of the rotor propellers, so that when the rotor propellers are started, the distances between the rotor propellers and the fuselage main body are large, airflow disturbance is facilitated, and the stability of the aircrafts is improved. And when the rotor wing propellers are not used, the rotor wing propellers are gradually close to the fuselage main body under the action of gravity.
