DETAILED DESCRIPTION

[0018] The utility model is further described below in combination with the drawings:

[0019] As Figures 1-4 shown, a movable waist blocking rod door type scaffold is composed of a lifting frame 1, a connecting rod 2 and a telescopic adjusting waist blocking rod 3;

[0020] The lifting frame 1 is provided with two groups, and the two groups of lifting frames 1 are connected through connecting rods 2; a telescopic waist adjusting rod 3 is fixed on any one of the lifting frames 1; and a telescopic top frame 4 is installed on the top of the lifting frame 1;

[0022] The telescopic top frame 4 is fixedly installed with side moving climbing support frames 4 at both ends; the bottom of the side moving climbing support frame 4 is fixedly installed with a plurality of moving trolley wheels 6; the distance between the two groups of telescopic vertical rods 12 is lengthened under the telescopic adjustment of the telescopic waist adjusting rod 3, so that the telescopic top frame 4 is lowered, the moving trolley wheels 6 are supported on the ground, and the moving is facilitated; when in use, the reverse operation is performed, so that the telescopic top frame 4 is raised, and the user is conveniently lifted to a certain height;

[0023] A plurality of groups of pedals 7 are installed on the telescopic top frame 4, and the pedals 7 are convenient to step on.

[0024] As shown in Figures 1-4 The utility model discloses the following more optimized specific structure:

[0025] The side moving climbing support frame 5 is provided with a plurality of ladder holes, and the climbing is facilitated.

[0026] The telescopic vertical rod 12 is composed of a bottom cylinder 121 and a top inserting column 122 inserted at the top end of the bottom cylinder 121; a plurality of pin holes are arranged on the top inserting column 122; and a vertical rod limiting pin is installed on the bottom cylinder 121, so that the auxiliary stable limiting is facilitated.

[0027] The telescopic waist adjusting rod 3 is composed of a bidirectional screw rod 31 and end side rotary connection cylinders 32 rotatably connected at both ends of the bidirectional screw rod 31; a rotating part 33 is installed at the middle of the bidirectional screw rod 31, so that the bidirectional screw rod 31 is driven to rotate; and a bidirectional screw thread is arranged on the bidirectional screw rod 31, so that the end side rotary connection cylinders 32 on both sides are moved oppositely.
