The transmission gear set comprises a control gear and a power gear which are meshed with each other, each target distance telescopic piece is in transmission connection with the control gear and used for clamping a part to be coated, the power gear is driven by a motor, and when the power gear drives the control gear to rotate, the target distance telescopic pieces are close to or away from the target distance rotating frame. According to the utility model, the target distance can be accurately adjusted in the coating process, so that the coating uniformity, the process flexibility and the film layer quality are improved.

The application relates to a parking space lock technical field, and discloses a curbstone lock which comprises a lock box, a vehicle blocking arm and a driving mechanism, the lock box is provided with a containing cavity; one end of the vehicle blocking arm is hinged to the lock box and can rotate along a second direction around the hinge point, so that the vehicle blocking arm can extend out of the containing cavity or retract into the containing cavity; the driving mechanism comprises a driving piece fixed to the lock box, a moving block arranged in the containing cavity and at least one connecting strip, one end of the connecting strip is connected with the moving block, the other end is connected with the vehicle blocking arm, the driving piece is in transmission connection with the moving block and is used for driving the moving block to reciprocate, so as to drive the connecting strip to drive the vehicle blocking arm to switch between a storage state and an extending state; when the vehicle blocking arm is in the extending state, an included angle is formed between the connecting strip and the lock box. The curbstone lock can effectively prevent the vehicle from violently pushing away the vehicle blocking arm to escape the toll, can significantly reduce the transitional shaking or deformation of the vehicle blocking arm caused by the impact, can reduce the fatigue damage caused by repeated impact, and can prolong the service life of the vehicle blocking arm.

This utility model discloses a rotating telescope, belonging to the technical field of telescopes. It includes a telescope body, a rotating base, and a mounting base. The telescope body is mounted on the rotating base, and the rotating base is mounted on the mounting base. A control main board is disposed within the telescope body. A rotating assembly is disposed within the cavity of the rotating base. The rotating assembly includes: a drive component electrically connected to the control main board; a gear connected to the output shaft of the drive component; an external gear ring fixedly connected to the mounting base, the external gear ring meshing with the gear; an encoder electrically connected to the drive component via the control main board; and a knob mounted on the rotating base, one end located outside the rotating base, and the other end located inside the cavity and connected to the encoder. This utility model, by incorporating the encoder within the rotating base and using the connected knob, allows for precise control of the rotation angle of the rotating base.

The utility model provides a kind of worm gear speed reducer for pipe bender, including shell, the worm as input end is rotationally arranged in the shell, the worm gear shaft with worm wheel is rotationally arranged in the shell, worm gear shaft and worm are perpendicular to each other, the hollow portion of worm gear shaft is worn and is equipped with output shaft, output shaft is coaxially connected with worm gear shaft by the mode of key connection.This worm gear speed reducer for pipe bender realizes ninety degrees vertical steering of power input end and output end using intermeshing worm wheel and worm, this transmission mode not only can ingeniously adapt the space layout requirement of pipe bender operation, avoid the interference of power transmission path and processing station, but also can reduce power loss and vibration in steering process by the inherent low back gap, high transmission stability characteristics of worm gear drive.

The utility model discloses a reinforced eddy current sensor relates to eddy current sensor technical field, including signal processor, sensor probe and positioning adjusting mechanism, the signal processor is connected with sensor probe through the connecting cable, the utility model adopts servo motor drive ball screw to adjust sensor probe, has reduced the complexity of manual operation, and because ball screw has smaller friction coefficient and lower wear, the return gap is smaller in the adjustment process, and the error is smaller when repeating positioning, and, after adjusting, lock through the band brake function of servo motor, compares traditional double nut locking, servo motor initiative lock axle, locking force is big, and the anti -vibration and impact performance is excellent, even in complex environment also can keep stable, thereby can keep the positioning performance of stable, has greatly promoted the precision and reliability of equipment, is applicable to the occasion that sensor probe needs frequently adjusting or precision adjustment.

The utility model discloses a speed reducing motor capable of adjusting back clearance, which comprises a box body, a box cover, a transition flange, a motor main body, a transmission assembly and an output shaft, the box cover is fixedly arranged on the box body, the surface of the box cover is provided with a circular mounting groove, a through hole is arranged in the circular mounting groove, and the axis of the through hole deviates from the axis of the circular mounting groove; the transition flange is of a hollow annular structure, the transition flange is rotatably mounted in the circular mounting groove, and the transition flange is connected with the box cover through a detachable connecting piece; the motor main body is fixedly arranged on the transition flange, and a rotating shaft of the motor main body is inserted into the through hole; a gear shaft is integrally formed on the rotating shaft; the output shaft is rotationally arranged on the box body, an output tooth piece is fixedly arranged on the output shaft, and the transmission assembly is arranged between the gear shaft and the output tooth piece in a transmission mode. The gear motor has the advantages that the gap between the gear shaft and the transmission gear sheet can be adjusted by rotating the transition flange, so that the gear motor has higher transmission precision.
