Detailed description of the invention

In FIG, screw lift is made up of two expansion links.Outer tube 4 is made with aluminium alloys, greatly, little pipe, greatly, little rotating disc and square tube, at outer tube 4 with large, in little pipe, car has trapezoidal internal thread 3, the pitch of each internal thread 3 is equal, greatly, little rotating disc is got on the bus trapezoidal external screw thread, externally threaded pitch is also equal, in, external screw thread coordinates, greatly, by there being square tube in little rotating disc, each interior pipe 2 is enclosed within outer tube 4 all by size, the bottom of each interior pipe is all pressed corresponding greatly sizeable, on little rotating disc, large rotating disc rotates the interior pipe of rising jack-up above it and rises, interior pipe 2 rises and drives the rotating disc combined with it also to rise, the pitch of Yin Genei pipe is equal, so the distance that each interior pipe rises is also equal, the length that each interior pipe rises should be less than the length of each interior pipe, overlap should be had between each inner tube length, just can guarantee the firm stable of lift, the number of turns that rotating disc rotates should be less than the Internal Pipe Thread number of turns, in order to ensure the safety of the person, in the bottom of outer tube by there being slipmat 6, by there being wheel disc 5 below large rotating disc, the endoporus of wheel disc 5 and the bottom close-fitting of square tube, wheel disc 5 can be connected with hand-operated wheel in the absence of a power supply, also can be connected with motor, along with the rotation of wheel disc, every root square tube is all along with rotation, be placed on interior pipe above rotating disc also along with rising, twist-type telescopic bar is constantly extended, outer tube is welded with multistep ladder shelves 1, the top of each interior pipe is all welded with step ladder shelves 1, along with each is large, the rising of little rotating disc, drive each interior pipe also to rise thereupon, reach the object of ladder lifting.

In fig. 2, screw lift is made up of two expansion links.Outer tube is made with aluminium alloys, greatly, little pipe, greatly, little rotating disc and square tube 9, at outer tube with large, in little pipe, car has trapezoidal internal thread 3, the pitch of each internal thread 3 is equal, greatly, little rotating disc is got on the bus trapezoidal external screw thread, externally threaded pitch is also equal, in, external screw thread coordinates, greatly, by there being square tube 9 in little rotating disc, each interior pipe overlaps within the outer tube all by size, the bottom of each interior pipe is all pressed corresponding greatly sizeable, on little rotating disc, large rotating disc rotates the interior pipe of rising jack-up above it and rises, interior pipe 2 rises and drives the rotating disc 7 combined with it also to rise, the pitch of Yin Genei pipe is equal, so the distance that each interior pipe rises is also equal, the length that each interior pipe rises should be less than the length of each interior pipe, overlap should be had between each inner tube length, just can guarantee the firm stable of lift, the number of turns that rotating disc rotates should be less than the Internal Pipe Thread number of turns, wheel disc 5 is provided with below large rotating disc, the endoporus of wheel disc 5 and the bottom close-fitting of square tube, wheel disc 5 can be connected with hand-operated wheel in the absence of a power supply, also can be connected with motor, along with the rotation of wheel disc, every root square tube is all along with rotation, be placed on interior pipe above rotating disc also along with rising, screw type expansion link is constantly extended, outer tube is welded with multistep ladder shelves 1, the top of each interior pipe is all welded with step ladder shelves 1, along with each is large, the rising of little rotating disc, drive each interior pipe also to rise thereupon, reach the object of ladder lifting.

In figure 3, at the external screw thread 8 that rotating disc 7 is got on the bus trapezoidal, the pitch of external screw thread 8 is also equal, and internal and external screw thread coordinates, by there being square tube 9 in rotating disc 7.
