2 upper surface of pressing plate is higher than pedal upper surface, and 2 lower surface of pressing plate is less than pedal lower surface.Pedal height becomes
It is 5 centimetres to change range, and the thickness of pressing plate 2 is more than 5 centimetres, can step on pedal, and unclamp between Chain cushion and pedestal
Fixed connection apparatus.The side of left and right two of pressing plate 2 is that monoclinic is trapezoidal, and than bottom side length, bevel edge, which is located at, to advance for trapezoidal top
Direction, bevel edge inclined downward backward are arc transition between bevel edge and bottom edge.
Pressing plate 2 is located at before the small arm of force 4, and the small arm of force 4 does not connect with seat back before the front surface pressure pedal of pressing plate 2
It touches.In a forward direction, with the front surface of pressing plate 2 compared with the distance between 4 front end of the small arm of force, pedal and seat back
Between distance closer to.The small arm of force 4 is contacted with seat back after the front surface pressure pedal of pressing plate 2.In a forward direction, with
The rear surface of pressing plate 2 compared with the distance between 4 front end of the small arm of force, pedal between seat back at a distance from it is farther.Pressing plate 2
Length be 13 centimetres.
The arm of force 3 is linear, is fixed on the left and right side of car body 1, protrudes horizontally up to the left and right.The arm of force 3 is apart from 95 lis of ground
Rice.
In 1 both sides of car body, setting engaging lug is articulated and connected with the arm of force 3, is arranged two along the width direction of trolley in hinged ear
The central axis of a hinge hole, hinge hole is parallel with trolley direction of advance, and setting two is corresponding hinged on the arm of force 3 accordingly
The arm of force 3, is mounted at engaging lug when work and axis pin is used to wear and be connected in hinge hole so that the arm of force 3 and car body 1 are fixed and connected by hole
It connects, when trolley passes through relatively narrow road, will wherein extract out an axis pin, the arm of force 3 is rotated towards close to the direction of 1 vehicle body of car body,
The width for reducing trolley entirety, convenient for passing through slype.
The end of the arm of force 3 is corresponding at seat rotary shaft, and the contact position of the two before seat rotary shaft and to the greatest extent may be used
It can be close to rotary shaft.
The small arm of force 4 is the linear extended horizontally forward.The small arm of force 4 is fixed on the arm of force 3, fixed connection place to the arm of force 3
Distance between end is a quarter of seat width.The length of the small arm of force 4 is 0.433 times of seat width
Pull rod 5 is fold-line-shaped, and one end is articulated and connected with car body rear surface, and first segment extends to rear ramp, second segment
It protrudes horizontally up to the left and right again.
Torsionspring is equipped at pull rod 5 and 1 articulated connection of car body.The axis of torsionspring is perpendicular to horizontal plane.Torsionspring
Two torque arm, one side for being fixed on car body 1, another is fixed on the side wall of pull rod 5.After 5 first segment of pull rod and car body
Surface is in 45 degree of angles.Pull rod 5 can only rearward be swung when bearing certain thrust.When no longer stress in the elastic force of torsionspring
Pull rod 5 is restored to original position under effect.
The end of pull rod 5 is semicircle.It is circular arc portion with seat contact portion, pull rod end can push and rotating seat
Chair is completed the when of rotating when seat and is skidded off automatically from seating edge, do not influence trolley advance.

Seat rotation is pushed with smaller friction when contact.
5 end of pull rod is corresponding at seat rotary shaft, vertical range and the seat rotation of 5 end of pull rod to vehicle body side
The vertical range of axis to vehicle body side is suitable.
Plane is equipped with the handle for facilitating cart after car body 1.Each one of handle or so is located at sustained height.Two handles
It is each perpendicular to horizontal plane or parallel with horizontal plane.
Operation principle or application method：
By taking the seat on the right side of rotating cart as an example.
Trolley is advanced forwards, and pressing plate 2 is contacted with pedal, then pedal is depressed and unclamps seat and is fixedly connected with dress
It sets.Later, the small arm of force 4 is contacted with seat rear surface, the seat width of the rotary shaft of contact position and seat at a distance of a quarter.
The radius of turn of seat is the half of seat width.The small arm of force 4 is detached with seat when the small arm of force 4 pushes seat to rotate 60 degree, power
3 end of arm starts to contact with seat, and contact position is at seat rotary shaft.The block of the arm of force 3 is rolled in seat rear surface,
It pushes seat to rotate to 90 degree, keeps backrest parallel with trolley direction of advance.The following arm of force 3 is detached with seat, and seat exists
Rotation is more than 90 degree under effect of inertia.Hereafter, pull rod 5 is contacted with seat, and contact position is the right side edge of original seat, this portion
Divide and has rotated to apart from the position of half of seat width of seat base.The end of the arm of force 3 is with the end of pull rod 5 in direction of advance
A upper seat width apart.Pull rod 5 continues rotary seat, and until seat rotation 180 degree and automatic card-loading is on pedestal.Trolley
Continue to move ahead, then 5 swing backward of pull rod is skidded off from seat.
Seat on the left of rotating cart is similarly.The single work for pushing trolley to complete rotary seat.
