4results about How to "Increase turning force" patented technology

The utility model relates to the technical field of equipment maintenance tools, in particular to a novel portable durable motor rotor bearing dismounting tool which comprises a cylinder and a T-shaped lead screw, the T-shaped lead screw is arranged on the center line of the cylinder, the upper end of the T-shaped lead screw is in threaded connection with an upper cover of the cylinder through a nut, and the lower end of the T-shaped lead screw is in threaded connection with the upper cover of the cylinder. The middle of the T-shaped wire is in threaded connection with a center balance force rod, and the two ends of the center balance force rod penetrate through the cylinder to extend. Fixing plates are arranged on the two sides of the lower end of the cylinder respectively and connected with an n-shaped plate through nuts, and a groove is formed in the middle of the n-shaped plate. The device is convenient to carry, light, fast and flexible to use, and suitable for a light operation mode which can be operated by 1-2 persons.

This invention relates to the field of rock and soil exploration technology, and discloses a rock and soil drilling exploration device for engineering construction. The device includes a main body with a support frame rotatably connected inside. A drill rod is mounted on the side wall of the support frame. When two arc-shaped plates form a cross shape around the outer surface of the drill rod, the invention enhances the rotational force of the motor, causing the motor to drive the drill rod to rotate and disengage from a jammed state via a threaded shaft. After disengagement, the hydraulic rod retracts to its output end. As the hydraulic rod retracts, it resets the two arc-shaped plates, allowing them to fit onto the outer surface of the drill rod, enabling normal operation. This reduces the likelihood of the drill rod jamming when encountering harder rock layers during rotation within the rock and soil strata, thus improving the exploration quality of the device.

The utility model relates to the field of lithium battery diaphragms, and discloses a liquid scraping device which comprises a speed reducing motor, a coupler, a liquid scraping roller, two first bearing seats, two linear moving mechanisms and two support plates, the speed reducing motor drives the liquid scraping roller to rotate through the coupler; the two ends of the liquid scraping roller penetrate through the first bearing seats correspondingly, and the first bearing seats rotationally support the liquid scraping roller through bearings. Each support plate is provided with a linear moving mechanism, and the two linear moving mechanisms drive the bearing seats to move and drive the liquid scraping rollers to be away from or close to the thin film. According to the liquid scraping roller, the rotating function is added, and the technical problems that a traditional liquid scraping roller is unpowered, and precipitates can be generated on the surface of the roller after long-time use are solved. Precipitates cannot be attached to the surface of the thin film, and the quality of the thin film is improved.

This utility model relates to the technical field of paper feeding and processing, and discloses an adjustable pressure feeding mechanism for an automatic feeding flatbed machine. It includes two parallel supports, with an adjusting rod between the lower parts of the supports. A sleeve is provided on one side of each support facing each other, and a connecting shaft is provided on one side of each sleeve. The connecting shaft passes through the supports and has an adjusting structure at its end for adjusting the rotational resistance of the sleeve. This utility model adjusts the rotational resistance of the connecting shaft through the adjusting structure, thereby adjusting the rotational speed of the sleeve. The adjusting structure works by rotating a threaded sleeve, which, through a compression spring, presses against a compression sleeve, causing the compression sleeve to abut against a fixed seat. This increases the resistance of the sleeve, reducing the power transmitted to the connecting shaft, thus limiting the rotational speed of the sleeve and preventing stacking.
