Description

Long lever labor-saving type adjusting handrail Technical Field The utility model relates to an adjusting handrail, in particular to a long-lever labor-saving adjusting handrail. Background The armrests of office chairs in the market today are usually fixed structures, and are partially provided with height adjusting structures, so that when the back of a human body leans backwards, the armrests cannot rotate backwards. When the human body is inclined at a slightly excessive angle, the elbow only contacts the rear end of the armrest surface, but not the whole arm contacts the whole armrest surface. When the arms rest, the arms cannot be positioned at a comfortable position, and the use experience is affected. In addition, the existing armrest structure is laborious when the adjusting range is too large. Therefore, it is necessary to provide a long lever labor-saving adjustment armrest. Disclosure of utility model The utility model aims to solve the technical problem of providing a long-lever labor-saving type adjusting handrail, which solves the problem that the existing handrail structure cannot be adjusted easily and greatly. The utility model provides a long-lever labor-saving type adjusting handrail which comprises a stand column, a fixing frame and a handrail surface, wherein the handrail surface is buckled on the fixing frame, a trigger and a fixed iron sheet are arranged on the fixing frame, the trigger and the fixed iron sheet are connected through a rotary cylinder, so that the trigger can rotate around the fixed iron sheet, a spring is arranged between the trigger and the fixing frame, one end of the spring is connected with the trigger, the other end of the spring is abutted against the fixing frame, an adjusting fixing sleeve is sleeved outside the stand column, and the adjusting fixing sleeve is fixedly arranged on the stand column through the fixing cylinder. The long lever labor-saving type adjusting handrail is characterized in that a back fixing iron sheet is arranged in the adjusting fixing sleeve, and the back fixing iron sheet is connected with the back connecting piece. The long lever labor-saving type adjusting handrail is characterized in that the handrail surface is locked and connected with the fixing frame through the flat head tapping screw. The long lever labor-saving type adjusting handrail is characterized in that the fixing frame is locked and connected with the upright post through the round head tapping screw. Compared with the prior art, the adjusting handrail has the advantages that the long lever structure formed by the trigger is utilized, the rotating cylinder is used as a fulcrum to be matched with the spring, so that a user can realize unlocking and angle adjustment with smaller pressing force, the labor-saving effect is achieved, the handrail surface can be greatly and easily adjusted, the overall structure is simple, the functions are reliable, and the assembly is convenient.
