Further, the rocker and the crank are equal in length and parallel to each other. Further, the device also comprises a lifting device and a rotating device; the lifting device comprises a rail column, a lifting platform and a lifting driving device, and the lifting driving device drives the lifting platform to lift along the rail column; the rotating device comprises a sleeve and a rotating driving device, the sleeve is sleeved outside the lifting platform, and the rotating driving device drives the sleeve to rotate along the axis of the rotating driving device; the capsule cage is fixedly connected with the sleeve through a radially arranged arm-holding beam. Furthermore, the rail column is fixed with the vertical face of the building through a fixing beam, one end of the fixing beam is fixedly connected with a ring beam of the building, and the other end of the fixing beam is fixedly connected with a column body of the rail column. Furthermore, the fixed beam comprises a sub-frame, the lifting platform and the sleeve are both provided with avoidance ports, and the avoidance ports are used for the sub-frame to pass through in the lifting process of the lifting platform. Further, the rotary driving device comprises an internal gear, a rotary gear and a rotary driver; the internal gear rigid coupling is at sleeve inner wall upside, and the rotary gear sets up four at least and evenly sets up along circumference, and the rotary gear all rotates to be connected on the elevating platform and with the internal gear meshing. Furthermore, a door-entering window is arranged on the vertical surface of the building, and the door-entering window is used for allowing the seat to extend into the building.

The inventor thinks that the technical scheme is suitable for outdoor use environment and is not suitable for indoor use environment, so the problem of the indoor manned elevator cannot be solved.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide an indoor manned elevator solves the problem that the current imported lead screw transmission mode is high in price.

In order to achieve the above purpose, the utility model adopts the technical scheme that: the indoor manned elevator comprises a guide rail, a lead screw, a lift car, a fixed frame, a power system, a control system and a power control cable; the car is fixed in on the mount, the car by driving system provides power, control system control the car is along the guide rail ascends and descends, the guide rail is used for the restriction and leads the up-and-down motion of car.

Further, the lead screw comprises a lead screw nut, and the power system comprises a servo motor; the servo motor drives the lead screw nut to rotate through the power control cable, and the rotary motion of the servo motor is converted into the linear motion of the car in a lead screw nut rotating mode; the lead screw is fixed and does not rotate.

Further, the lead screw adopts a butt joint mode.

Further, the control system is used for controlling the car to stop against the floor and controlling the locking in a power-off state and the stopping in an emergency stop.

The beneficial effects of the utility model reside in that, the utility model provides a pair of indoor manned elevator adopts neotype screw drive structure: the lead screw is fixed, the servo motor drives the lead screw nut to rotate through the power control cable, the rotary motion of the servo motor is converted into the linear motion of the car in a lead screw nut rotating mode, the lead screw has small transmission resistance, and the energy conversion efficiency is high; through the butt joint mode of lead screw solves the lead screw overlength and causes the inconvenient problem of transportation and installation.
