The application discloses a short-circuit prevention valve seat high-frequency quenching induction coil and relates to the technical field of induction coils. The induction coil comprises an induction pipe, the induction pipe is bent in multiple turns, the induction pipe is divided into a wiring end and a separation end after being bent, further comprises an insulating pipe for reducing the magnetic force influence of the induction pipe, a center positioning mechanism for automatically clamping and correcting the workpiece during quenching, and a strength adjusting mechanism for adjusting the number of turns of the induction pipe. The short-circuit prevention valve seat high-frequency quenching induction coil can not only move synchronously with the induction pipe through the center positioning mechanism to improve portability, but also automatically corrects the position of the workpiece when the induction pipe is placed on the workpiece before quenching, so that the workpiece and the induction pipe are on the same center line, thereby improving the quenching uniformity. When the inclination angle of the induction pipe is too large, the induction pipe cannot be normally placed on the workpiece, thereby reminding the operator.

The application relates to the technical field of clothing bonding machines, in particular to a clothing bonding device with controllable bonding pressure, which comprises a workbench and a base plate installed above the workbench, a frame is fixedly connected to the top of the workbench, two guide assemblies are arranged on the inner side of the frame, and a pressing plate is arranged between the two guide assemblies; the clothing bonding device can be used for adjusting the bonding force on the clothing by setting a bonding assembly, a driving assembly, a base plate, a plate-type pressure sensor and a display, and the hand wheel drives the worm to rotate to engage the worm gear, so that the stud can be threadedly driven in the worm gear, the position of the bonding plate can be changed, the bonding force on the clothing can be adjusted when the clothing is pressed and bonded, the bonding force on the clothing can be adjusted, the bonding quality of the clothing is improved, the plate-type pressure sensor and the display can display the pressure at the moment, the clothing bonding pressure can be adjusted to an appropriate force, and the staff can observe, so that the bonding force on the clothing can be conveniently controlled.

The utility model discloses an illumination regulation and control system suitable for facility agriculture, and relates to the field of facility agriculture illumination regulation and control, the illumination regulation and control system comprises a shed body, a transmission mechanism is arranged in an inner cavity of the shed body, and a shielding mechanism is arranged on one side of the transmission mechanism; the transmission mechanism comprises a driving bevel gear, a universal joint transmission rod and an upper lead screw, a second bevel gear is fixedly installed on one side of the upper lead screw, and first bevel gears are arranged at the two ends of the universal joint transmission rod. Under the action of the transmission mechanism, output power of the motor is dispersed into three ports to be output, so that power output is performed, operation of the motor is controlled, and the output end of the motor drives the driving bevel gear to rotate so as to drive the two first bevel gears and the second bevel gear to rotate; the universal joint transmission rod rotates to drive the first bevel gear at the other end to rotate, so that the third bevel gear is driven to rotate, the side screw rod is further driven to rotate, power is output to the needed position, and the function of changing the power output direction is achieved.

The invention provides a display system for preventing and treating myopia in order to solve the problem that a traditional intelligent terminal display screen easily enables a viewer to form myopia in the long-term use process. The display system for preventing and treating myopia comprises a 3D display and glasses. The 3D display is conventionally arranged, and a stereoscopic image is arranged to be in a positive parallax mode and displayed behind a screen of the 3D display. The glasses comprise lenses, a first polaroid and a second polaroid, the lenses have diopters, the absolute value of the diopters of the lenses is lower than the absolute value of the correct diopters of conventional myopic glasses of a user, and small holes are reserved in the polaroids, so that the glasses form defocus imaging. Based on far sight distance and out-of-focus imaging of 3D display, eye axis growth can be inhibited, and myopia deepening can be delayed.
