The utility model discloses a kind of thread structures of optical lens, including back seat and lens barrel, back seat is equipped with rectangular internal thread;Lens barrel is equipped with trapezoidal external thread matched with rectangular internal thread;Two corner parts of the crest of rectangular internal thread are in contact with the side of trapezoidal external thread;By adopting the cooperation of rectangular internal thread and trapezoidal external thread, and design the crest corner part of rectangular internal thread is in contact with the side of trapezoidal external thread, the close cooperation of thread and uniform stress are realized.This structure not only enhances the stability of threaded connection, but also makes wear mainly concentrate in the crest corner part of rectangular internal thread, facilitate control and predict wear site, reduce the risk of optical lens imaging quality decline caused by thread loosening.In addition, the matching mode can form stable friction in the assembly process, which helps to realize more accurate torque control, further improves the precision and reliability of optical lens assembly.

The utility model relates to the field of wrenches, and discloses a portable directional torsion calibration wrench which comprises a handle, a round groove is formed in the bottom of the handle, a rotating disc is rotatably installed in the round groove, a connecting rod is arranged at the bottom of the rotating disc, a rotating shaft is rotatably installed at the top of the handle, and a gear is arranged on the outer wall of the rotating shaft in a sleeved mode. The top of the rotating shaft is fixedly provided with a torsion detection device, the top of the handle is slidably provided with a rack, and the wrench further comprises a rotation-free assembly, through the design of the rotation-free assembly, a workpiece can be fastened or loosened under the condition that the wrench body is not rotated, the working capacity of the wrench in a narrow space is greatly improved through the characteristic, and the working efficiency of the wrench is improved. The problem that a traditional wrench cannot work due to space limitation is solved, pulling force of an operator is converted into rotating power of the wrench, operation steps are simplified, working time is shortened, meanwhile, due to the fact that the wrench body does not need to be frequently rotated, physical output of the operator is correspondingly reduced, and working efficiency is further improved.

This utility model discloses a vector water supply device equipped with a pump control unit, relating to the field of water supply equipment technology. It includes a water pump module, a pressure stabilizing tank, a first pressure sensor, and a control cabinet module. The water pump module comprises multiple vector variable frequency pumps, each with its inlet connected to a water tank for water supply. The outlets of these pumps are connected in parallel to a common outlet manifold. Each pump integrates a variable frequency drive board, a PLC control board, and a status sensor. The pressure stabilizing tank is connected in parallel between the inlet and outlet of the water pump module, and an electrically controlled valve is installed on the delivery pipeline. The first pressure sensor is installed on the outlet manifold. This utility model employs distributed control, improving product reliability and reducing operating costs. It allows for monitoring of the equipment's operating status, preventing prolonged operation in a faulty state and reducing maintenance costs.

The present disclosure provides a clutch control method, a control device, a storage medium and a gearbox controller. The method comprises: when the current vehicle state enters the slip state, determining the target slip speed of the clutch corresponding to the current gear; then judging whether the current vehicle state meets the state of collecting the torque deviation of the clutch, if so, collecting the torque deviation once, storing the torque deviation, and at the end of the adjustment period, accumulating all the torque deviations collected previously, taking the average according to the cumulative number to obtain the torque average deviation, if the torque average deviation exceeds the preset deviation threshold, recording the torque average deviation; if the current vehicle state meets the deviation application state, adjusting the current clutch friction coefficient according to the recorded average deviation, which can realize the automatic adjustment of the clutch friction coefficient, and further realize the accurate control of the clutch torque.

This invention discloses a connector thread life testing device, comprising a base, a drive shaft, a three-jaw chuck holder, and fixed three jaws. A second vertical plate is vertically mounted on the base. The drive shaft, driven by a stepper motor, is rotatably mounted on the second vertical plate. Two friction plates I, a clutch driven plate, and two friction plates II are sequentially mounted on the drive shaft from near to away from the stepper motor. A pressure adjusting component is mounted on the drive shaft to adjust the pressure between the two friction plates II and the clutch driven plate. One end of the three-jaw chuck holder is connected to one end of a rotating three-jaw chuck, and the other end is connected to the clutch driven plate. The other end of the rotating three-jaw chuck clamps the male connector head. The fixed three jaws are horizontally movable above the base, and one end of the fixed three jaws clamps the female connector head. The female connector head abuts against the male connector head via a spring-loaded component. This invention improves testing efficiency, accuracy, and stability.
