Description

Swing arm driver Technical Field The utility model relates to the field of bathrooms, in particular to a swing arm driver. Background Chinese patent CN208533659U is a double-capacity water drain valve, which has two pull rings of small and large flushing, and the corresponding pull ring is selected to be pulled up according to different water discharge demands. The water drain valve is arranged in the water tank, and the existing structure realizes mechanical transmission through a connecting structure. The mechanical transmission structure has a remarkable disadvantage that in public places, the hands need to contact and press the buttons, so that bacteria propagation can be promoted, and the existing non-contact sensor is used for controlling the driver to open the water drain valve, so that contact can be effectively avoided. Thus, a driver is needed. Disclosure of utility model Aiming at the defects of the prior art, the main purpose of the utility model is to overcome the defects of the prior art, and discloses a swing arm driver which comprises a shell, a servo motor, a driving arm and a lifting hook, wherein the shell is provided with a mounting cavity of the servo motor, the servo motor is fixed in the mounting cavity, the driving arm is connected with the servo motor, the shell is provided with a guide part, the lifting hook is vertically and slidingly connected with the guide part, and the driving arm is driven to reciprocate by the servo motor to provide an upward driving force for the lifting hook. Further, the guiding part comprises a first guide bar arranged on the shell, and a first guide groove is formed between the first guide bar and the shell. Further, the lifting hook comprises a lifting hook body, a driving part and a hooking part, wherein the driving part and the hooking part are arranged on the lifting hook body, the lifting hook body is in sliding connection with the guiding part, the hooking part is hooked on the water drain valve, and the driving arm pushes the lifting hook to move upwards through the driving part. Further, the contact surface between the driving part and the driving arm is an inclined surface. Further, the driving arm comprises a connecting arm and a contact part, and the contact surface of the contact part and the lifting hook is of an arc structure. Further, a connecting hole is formed in one side of the connecting arm, and convex keys are arranged on the inner wall of the connecting hole at intervals. Further, the lifting hook body is provided with a second guide groove matched with the guide part and a second guide bar matched with the first guide groove of the guide part. Further, the guide part is in clearance fit with the second guide groove, and the first guide groove is in clearance fit with the second guide bar. Further, a limiting block is arranged on the shell, a limiting part is arranged on the lifting hook, and the lower limit position of the lifting hook is determined by the limiting block and the limiting part.
