Abstract
The utility model relates to a full automatic jack which is characterized in that a lock ring roll 23 is fastened on a jack body 1; a shaft 18 passes through the inner holes of two bearing supports 19 fixed on the lock ring roll 23; the other end of the shaft 18 is fixedly connected with a crank 5, the lower end of a link lever 4 is fixedly connected with a shaft 9 which passes through the inner hole of a bearing to be hinged with the crank 5; the upper end of the link lever is hinged with one end of a pressure lever 3; the other end of the pressure lever 3 is spliced in the original hand sleeve 2 of the jack and is fastened by a screw nail. The device has the advantages that: first, the jack is suitable for the operation in a narrow space; second, the outer of the shaft 18 is connected with the pneumatic device such as a pneumatic wrench (a wind gun) to drive a link mechanism to move, so as to cause the pressure lever to reciprocate, thereby improving the lifting efficiency of the jack.
Description
Technical field
The utility model relates to a kind of jack, particularly a kind of jack with automatic hoisting mechanism.
Background technology
Jack is a kind of easy jacking system, is mainly used in automobile repair and big machinery occasions such as adjusting are installed.Traditional jack armrest shakes the depression bar reciprocally swinging, makes jack piston rise the jack-up weight.When this device weak point is the depression bar reciprocally swinging, need bigger operational space, and hand efficient is lower; Often the space is limited and use the occasion of jack, inconvenient depression bar swing, limited this device flexibly and high-efficient characteristic bring into play.Extensively retrieve at the problems referred to above, still find no improvement project this problem.
The utility model content
The purpose of this utility model is can not adapt to the narrow and small occasion in operational space in order to overcome prior art, and the defective of depression bar inefficiency hand-manipulated and a kind of full automaticity jack is provided.
For achieving the above object, the utility model has been taked following technical scheme: a kind of full automaticity jack, it comprises jack body and base, be connected with hydraulic actuating cylinder and piston rod on the base, also connect a bearing on the base, a hinged sleeve pipe on it, the sleeve pipe middle part is hinged with piston rod, a depression bar is set in the sleeve pipe, it is characterized in that a bearing seat is set on the jack body, a transmission shaft is set in the bearing seat, this axle one end is provided with connector, the affixed crank of the other end, the hinged connecting rod of the crank other end, the other end and the depression bar of connecting rod are hinged, and they form a piston crank mechanism, and power is imported by transmission shaft.Described bearing seat can be arranged on the base, also can be connected on the jack body with other structure; Described shaft adapter is outer square toes connection structure, so that it is connected with air nutsetter air driven toolss such as (being commonly called as the wind big gun), drives depression bar by piston crank mechanism and swings up and down, and jack is risen automatically.
The utility model adopts technique scheme, and its advantage is:
1. the utility model adopts connecting rod mechanism to replace hand depression bar reciprocally swinging, saves the operational space, is suitable for the narrow and small occasion in operational space.
2. owing to adopt the interchangeable structure of joint, a joint and an axle union end fixed size, joint other end size can be formed the interchangeable series of many packet sizes, conveniently connects tools selection with joint.
3. owing to adopt joint design, air driven toolss such as joint and air nutsetter, wind plane link, and by air driven tools drive link mechanism kinematic, make the quick crank motion of fork, improve jack and rise efficient.
