4results about How to "Realize electric adjustment" patented technology

This utility model discloses a simple, electrically adjustable engineering vehicle, comprising: a U-shaped base, an electrical control box, electrically adjustable columns, and a testing machine connecting assembly. The lower end of the U-shaped base is equipped with several casters, and the electrical control box is located at the upper end of the U-shaped base. Two electrically adjustable columns are positioned on either side of the U-shaped base, with one column positioned close to the electrical control box. The testing machine connecting assembly is mounted on the two electrically adjustable columns. By applying this utility model, a simple, electrically adjustable engineering vehicle is proposed. The electrical control box controls the raising and lowering of the electrically adjustable columns, enabling electric adjustment of the testing machine's height. This improves operator comfort and operational accuracy, allowing operators of different heights to quickly adjust the testing machine height according to their needs. Furthermore, by embedding the casters within the U-shaped base, the distance between the U-shaped base and the ground is reduced, improving the overall passability of the engineering vehicle.

The invention relates to a self-adaptive fast-adjusting pole climbing device which comprises a connecting pipe, a rear pedal, a front pedal and a hoop, the rear end of the connecting pipe is connected with an adjusting guide rail extending backwards, the rear pedal is installed on the rear portion of the adjusting guide rail, and the front pedal is installed at the front end of the adjusting guide rail and the rear end of the connecting pipe; the front end of the connecting pipe bends towards one side and is fixedly provided with a hoop sleeve, a U-shaped structure is formed between the connecting pipe and the hoop, and the hoop is provided with a bent rod part and a straight rod part which penetrates through the hoop sleeve and is in sliding fit with the hoop sleeve. An electric driving mechanism used for driving the straight rod part to slide relative to the hoop sleeve is arranged on the side portion of the hoop sleeve so that the clamping distance between the connecting pipe and the hoop can be adjusted. Electric adjustment of the clamping distance between the connecting pipe and the hoop is achieved, the operation steps are simplified, the adjustment time is shortened, the pole climbing efficiency is remarkably improved, the pole climbing process is more efficient, operators do not need to have rich use experience, meanwhile, the falling risk is electrically reduced, and safety is improved.

This application discloses an adjustable-height liquid heater, including a base and a PCB board disposed inside the base, a heating module disposed on the base and electrically connected to the PCB board, a connecting bracket spanning the upper side of the base, a suspension assembly disposed on the upper side of the connecting bracket, a kettle detachably connected to the suspension assembly, and a lifting drive assembly disposed on the base, connected to the connecting bracket, and electrically connected to the PCB board. The lifting drive assembly is used to drive the connecting bracket to move the suspension assembly and the kettle up and down to adjust the position height of the kettle. This application achieves flexible adjustment of the kettle height to achieve the purpose of controlling the kettle's heating or keeping it warm. When the kettle is lifted to a high position by the lifting module, the baking space of the base is fully utilized, thereby further increasing the amount of food that can be baked, thus improving the multifunctionality and practicality of the liquid heater.

The application relates to the technical field of die-cutting equipment, and discloses a die-cutting mechanism with accurate positioning for a die-cutting machine, which comprises a pressing plate and a horizontal plate, the horizontal plate is arranged directly above the pressing plate, a cutting hole is formed in the pressing plate, a die-cutting cutter is fixedly installed below the horizontal plate directly above the cutting hole, a buffer mechanism is connected between the horizontal plate and the pressing plate on the two sides, a groove plate is arranged directly above the horizontal plate, an adjusting mechanism is connected between the groove plate and the horizontal plate, and an installation mechanism is arranged on the two sides of the groove plate. The automatic degree of the die-cuting mechanism is obviously improved through the control system, accurate setting and real-time monitoring of die-cutting parameters can be realized, manual intervention is reduced, only one person is needed to look after a single device, and the production efficiency is effectively improved.
