This utility model discloses a magnetic template quick-change device, which relates to the technical field of template changing devices. It includes a fixing component, a template component at the top of the fixing component, the template component comprising a module, a second permanent magnet block fixedly installed at the bottom of the module, and locking grooves at both ends of the module. The fixing component includes a housing, a lifting cavity inside the housing, a partition fixedly installed in the middle of the lifting cavity, a lifting plate slidably connected inside the lifting cavity, a first permanent magnet block fixedly installed at the top of the lifting plate, wedges fixedly installed at both ends of the lifting plate, and limit grooves inside both ends of the housing. Locking blocks are slidably connected inside the limit grooves, with one end of the locking block located inside the locking groove, and a wedge groove at the bottom of the locking block. This utility model can stably fix the template component when power is off, preventing loosening and detachment, and has high practical value.

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 utility model discloses a magnetic attraction support and a support assembly, the magnetic attraction support comprises a supporting member and a magnetic attraction assembly, and the supporting member is provided with a supporting surface; the magnetic attraction assembly comprises a driving part and a plurality of magnetic attraction parts, the magnetic attraction parts are located on the side, back to the supporting face, of the supporting part, at least part of the magnetic attraction parts are defined as first magnetic attraction parts, the first magnetic attraction parts can move relative to the supporting part, and the driving part is in transmission connection with the first magnetic attraction parts and used for driving the first magnetic attraction parts to move. Therefore, the opposite area between the first magnetic attraction part and the magnetically attractable part in the magnetically attractable equipment can be adjusted. Therefore, when the mobile phone is taken down from the magnetic bracket, the first magnetic part can be driven to move, so that the area opposite to the magnetically-attracted part in the magnetically-attracted equipment is reduced, and the magnetic force between the magnetically-attracted equipment and the magnetic bracket is reduced, so that the mobile phone is taken down more easily; therefore, the damage to the magnetically-attracted equipment and the magnetically-attracted bracket is reduced.

The utility model relates to cosmetic packing technical field, and disclose a kind of magnetic attraction type cosmetic lipstick replacement shell structure, including bottom disc, the top of bottom disc is fixedly installed with cylinder one, the top of bottom disc is equipped with circular groove one and cylinder two, the outer wall of cylinder one is equipped with spiral groove, the bottom of bottom disc is equipped with magnetic attraction assembly and bottom shell respectively, the outer wall of cylinder two is equipped with straight mouth groove, the inner wall of bottom shell is fixedly installed with outer tube, the outer wall of outer tube is equipped with U-shaped sliding slot, through the cooperation of strong magnet one and strong magnet two, through the cooperation of strong magnet one and strong magnet two, it is driven strong magnet one to realize and strong magnet two are separated by rotating threaded rod, and then reach strong magnet one and strong magnet two when replacing lipstick solid The weakening of magnetic force, to realize replacing lipstick solid more quickly, improve the environmental protection utilization of lipstick tube simultaneously, reduce the consumption capacity of using population.

The utility model relates to a miniature gear motor rotor. The technical problem to be solved by the utility model is to provide the miniature gear motor rotor. According to the technical scheme, the rotor comprises a rotor rotating shaft assembly, an iron core assembly and a rotor bearing, the rotor rotating shaft assembly comprises a rotating shaft, a rotating shaft inner core and a rotating shaft end cover, an inner core imbedding hole is formed in one end of the rotating shaft, an inner core butt joint seat is arranged at the bottom of a rotating shaft water inlet hole, a butt joint seat threaded hole is formed in the inner core butt joint seat, and the rotor bearing is arranged in the butt joint seat threaded hole. And the rotating shaft inner core comprises an inner core main body, an inner core bearing boss and an inner core thread mounting part which are arranged in sequence. The motor rotor has the advantages that the rotor water inlet channel of the rotating shaft and the inner core water outlet hole structure of the rotating shaft inner core form circulating flow of cooling water, heat generated in the operation process of the motor rotor is effectively taken away, the temperature of the motor rotor in the operation process is remarkably reduced, attenuation of magnetic force of the powerful magnets is delayed, and the service life of the motor rotor is prolonged. And the problem of motor stalling or noise caused by overheating is reduced.
