In order to achieve the above purpose, the utility model adopts the following technical scheme:
the utility model discloses an advertisement screen folding maintenance ladder, including a plurality of maintenance ladder units, a plurality of maintenance ladder units are fixed in on the advertisement screen back steelframe from top to bottom parallel. The overhaul ladder unit comprises a plurality of cross rods, a plurality of longitudinal rods and a plurality of connecting nodes. One end of the connecting node is fixedly connected to the steel frame on the back of the advertising screen, and the longitudinal rod is rotatably hinged with the connecting node; a limiting mechanism for limiting the rotation of the longitudinal rod is arranged at the joint of the connecting node and the longitudinal rod; the plurality of cross rods are hinged with the plurality of longitudinal rods respectively.
Further, the longitudinal rod is sleeved in the connecting node. The rotating shaft is respectively inserted into the connecting node and the longitudinal rod, and the bottom of the rotating shaft is screwed tightly by a nut.
Furthermore, the plurality of cross rods are lapped on the plurality of longitudinal rods in parallel. The rotating shafts are respectively inserted into the cross transverse rods and the vertical rods, and the bottoms of the rotating shafts are screwed tightly by nuts.
Further, the limiting mechanism comprises a limiting screw, a limiting through hole and a limiting threaded hole. The vertical rod is provided with a limiting threaded hole, the connecting node is provided with a limiting through hole matched with the limiting threaded hole, and the limiting screw penetrates through the limiting through hole to be in threaded connection with the limiting threaded hole.
Furthermore, the transverse rods and the longitudinal rods are steel pipes.
Furthermore, the transverse rods, the longitudinal rods and the connecting nodes are made of stainless steel.
The utility model discloses an useful part is:
1. the utility model discloses a set up folding maintenance ladder, the maintenance ladder expandes and uses stop gear restriction location during the use, and service function is the same with the maintenance ladder of current dead structure of welding. When not in use, the maintenance ladder can be folded, the volume is reduced after the maintenance ladder is folded, the occupied space is small, and the installation and the disassembly are convenient.

Description of the main component symbols:
the method comprises the following steps of 1-maintenance ladder unit, 2-cross rod, 3-longitudinal rod, 4-connecting node, 5-advertising screen back steel frame, 6-rotating shaft and 7-limiting screw.
Detailed Description
In order to make those skilled in the art better understand the technical solution of the present invention, the present invention is further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in figures 1-5, the utility model discloses an advertisement screen folding maintenance ladder, including a plurality of maintenance ladder units 1, a plurality of maintenance ladder units 1 parallel about are fixed in on the advertisement screen back steelframe 5. The overhaul ladder unit 1 comprises a plurality of cross rods 2, a plurality of longitudinal rods 3 and a plurality of connecting nodes 4. One end of each connecting node 4 is fixedly connected to the steel frame 5 on the back of the advertising screen, and the longitudinal rods 3 are hinged to the connecting nodes 4 in a left-right parallel mode. The longitudinal rod 3 is sleeved in the connecting node 4. The rotating shaft 6 is respectively inserted into the connecting node 4 and the longitudinal rod 3, and the bottom of the rotating shaft is screwed tightly by nuts, so that the longitudinal rod 3 can rotate relative to the connecting node 4.
And a limiting mechanism for limiting the rotation of the longitudinal rod is arranged at the joint of the connecting node 4 and the longitudinal rod 3. The limiting mechanism comprises a limiting screw 7, a limiting through hole and a limiting threaded hole. The longitudinal rod 3 is provided with a limiting threaded hole, the connecting node 4 is provided with a limiting through hole matched with the limiting threaded hole, and the limiting screw 7 penetrates through the limiting through hole to be in threaded connection with the limiting threaded hole.
The plurality of cross rods 2 are respectively hinged with the plurality of longitudinal rods 3. A plurality of transverse rods 2 are parallelly lapped on a plurality of longitudinal rods 3 from front to back.
