Description

Power adapter with detachable structure Technical Field The utility model relates to the technical field of electronic equipment, in particular to a power adapter with a detachable structure. Background The Power adapter (Power adapter) is a Power supply conversion device for small portable electronic equipment and electronic appliances, and is generally composed of components such as a shell, a transformer, an inductor, a capacitor, a control IC, a PCB (printed circuit board) and the like, and the working principle of the Power adapter is that the Power adapter is converted from alternating current input to direct current output, and the Power adapter can be divided into wall-inserted type and desktop-type Power conversion devices according to a connection mode. The existing power adapter generally adopts a bolt and nut or a cementing mode to fix and seal the adapter shell, when the adapter is required to be maintained, maintenance personnel are required to use tools to loosen the bolts, then the two shells can be pried apart to repair the inside, and the opening process is time-consuming and labor-consuming. Disclosure of utility model Accordingly, an object of the present utility model is to provide a power adapter with a detachable structure, so as to solve the above-mentioned technical problems in the related art. In order to achieve the purpose, the power adapter with the detachable structure comprises an upper shell and a lower shell, wherein a threaded block and a positioning block are arranged in the upper shell, a guide rod and a gear are arranged in the lower shell, a screw rod is connected to the top of the gear, a pull rod is connected to one side of the lower shell, racks are connected to two ends of the pull rod, a baffle is connected to the middle of one side of the lower shell through a rotating shaft, and an indexing pin is arranged on one side of the baffle. Further, the two sides of the lower shell are respectively connected with an input connector and an output connector, and components are installed inside the upper shell and the lower shell. Through adopting the technical scheme, the components are the general names of all parts, the inside of the components comprises a transformer, an inductor, a capacitor, a control IC, a PCB (printed Circuit Board) and the like, and the general principle is that mains supply enters through an input connector of an adapter, high-frequency noise and surge voltage in a power grid are filtered through an electromagnetic interference filter, alternating current is converted into pulsating direct current through a rectifier bridge, the rectified high-voltage direct current is sent into a high-frequency switch circuit, the quick on-off of a switch tube is controlled through a pulse width modulation chip, the high-voltage direct current is cut into high-frequency pulses, the high-frequency pulses are reduced through the high-frequency transformer, the voltage is reduced to be suitable for the level of the electric appliance by utilizing the electromagnetic induction principle, the reduced high-frequency alternating current pulses are rectified again into low-voltage direct current through a diode or a synchronous rectifier, and finally the output low-voltage direct current is transmitted to the electric appliance through an output connector connecting plug (such as a USB-C or a round plug) of the adapter, so as to charge or directly supply power to a battery. Furthermore, the four groups of guide rods are arranged and distributed in a rectangular array. Through adopting above-mentioned technical scheme, in-process that upper housing and lower shell break away from is led through the guide arm, under the lead screw drive for the screw thread piece can drive upper housing and lower shell and break away from, thereby reaches the purpose of quick dismantlement to upper housing and lower shell. Further, the rack is meshed with the gear. Through adopting above-mentioned technical scheme, under the staff pulling, the pull rod drives two racks and removes simultaneously for two gears opposite direction remove, thereby drive the lead screw and rotate, make the screw thread piece drive shell and shift up and break away from with lower shell, thereby need not the staff and use the instrument sled to open the adapter shell when dismantling the adapter, reach the purpose of dismantling the adapter fast. Further, the pull rod is U-shaped, and the pull rod penetrates through the lower shell. Through adopting above-mentioned technical scheme, the staff is through pulling or pushing the pull rod for the pull rod drives the rack and removes, thereby makes the gear drive lead screw corotation or reversal, and then makes the screw thread piece drive shell and reciprocates or move down, realizes the quick assembly disassembly to the adapter, and the pull rod size is less than the rack size, through "U" font setting and rack to the restriction of pull rod travel distance, avoid
