The working process of the adjusting mechanism 4 is as follows: when the operation is required to be carried out on the inclined plane of the stair, firstly, the control rod 48 is pulled leftwards, and the guide block 46 is driven to move leftwards by the leftward movement of the control rod 48; then, the guide block 46 moves leftwards to compress the spring 44, and under the contraction of the spring 44, the fixed inserting rod 47 is driven to exit from the inside of the fixed inserting hole 43 and move leftwards to reach the inside of the mounting frame 41, at this time, the adjusting rod 42 slides out from the inside of the left upright rod 1, and after being adjusted to a proper inclined plane, the fixed inserting hole 43 with the height required by the round hole on the left upright rod 1 is adjusted. Finally, the control rod 48 is released, the guide block 46 is driven to return to the original position under the action of the spring 44, and the right movement of the guide block 46 drives the fixing inserted rod 47 to be inserted into the fixing insertion hole 43, so that the adjusting rod 42 is fixed.

Through setting up adjustment mechanism 4, adjusted the height of scaffold frame one side, made its environment that can adapt to the stairwell, the convenience is worked at the stairwell. In addition, the stability of the whole scaffold is improved, the bottom of the right vertical rod 2 and the bottom of the adjusting rod 42 are both provided with supporting feet 5, and the supporting feet 5 can be square or horseshoe-shaped.

In the above embodiment, the structures of the left vertical rod 1 and the right vertical rod 2 are not limited as long as the multi-section telescopic function can be realized. For better understanding the utility model discloses a function provides the concrete structure of a left pole setting 1 and right pole setting 2 in this implementation.

As shown in fig. 5, the left vertical rod 1 and the right vertical rod 2 have the same structure and are formed by splicing at least two vertical tubes. The vertical pipes comprise a base pipe 11, a connecting ring 12 is fixedly arranged on the outer side of the upper portion of the base pipe 11, four connecting holes 13 are evenly distributed in the connecting ring 12, inserting circular holes 14 are formed in the portions, inserted into each other, of two adjacent vertical pipes at intervals, and a plug pin 15 is arranged in each inserting circular hole 14 to fix the two adjacent vertical pipes. Matched with the cross rod 3, the structure of the cross rod comprises a circular tube 31, two ends of the circular tube 31 are provided with connectors 32, and the connectors 32 are inserted into the connecting holes 13 so as to fixedly connect the cross rod 3 with the left vertical rods 1 and the right vertical rods 2 on two sides.

The standpipe and the cross rod 3 are made of carbon fiber, so that the weight of the whole scaffold can be reduced, and the scaffold is convenient to store and move. What provide in this embodiment is the extending structure of simplest bolt formula, pegs graft each other between the adjacent standpipe, and 14 height-adjusting of grafting round hole through the interval setting utilize bolt 15 to dismantle fixedly. To prevent the plug 15 from being lost, it can be fixed on the vertical tube at one side of the plug round hole 14 by using a chain or a rope. The connecting ring 12 can also be used as a limiting ring when being contracted, so that the vertical pipe at the upper part is prevented from falling into the vertical pipe at the lower part.

This embodiment is through the whole height that pole 2 conveniently adjusted the scaffold about telescopic, has made things convenient for the height that the user worked as required to adjust.

As shown in fig. 2, on the basis of the above embodiment, in order to further enhance the stability of the whole scaffold, a first inclined strut 6 and a second inclined strut 7 are provided between the left upright 1 and the right upright 2, two ends of the first inclined strut 6 and the second inclined strut 7 are respectively detachably connected to two adjacent crossbars 3, the first inclined strut 6 is provided at the outer side, and the second inclined strut 7 is provided at the inner side. In this embodiment, the connection manner of the first inclined strut 6 and the cross bar 3 is not particularly limited, and the two may be connected by using the existing scaffold connecting member, or may be connected by inserting the circular hole 14 and the plug pin 15.

It should be emphasized that the first inclined strut 6 and the second inclined strut 7 are fixed after the height adjustment of the left vertical rod 1 and the right vertical rod 2 is completed. When the bicycle is not in use, the first inclined strut 6 and the second inclined strut 7 are only hinged with the cross rod 3 on the upper part, and the lower part is a free end. And the first inclined strut 6 is arranged at the outer side, and the second inclined strut 7 is arranged at the inner side, so that the first inclined strut and the second inclined strut do not interfere with each other.

In addition, a dense mesh net 8 is arranged on the uppermost layer of the left upright stanchion 1 and the right upright stanchion 2. Through setting up dense mesh net 8, ensured operation personnel's safety (stepping on the eminence that empty etc. caused and falling), also prevented that operation instrument etc. from dropping, accidentally injure other personnel that the scaffold frame passed by. In practical use, the first inclined strut 6 and the second inclined strut 7 can be arranged only on the middle layer, and the dense mesh net 8 can be arranged only on the uppermost layer.

The scaffold in the above embodiments has the same size as that of a conventional scaffold, so that the scaffold plate and the ladder stand can be used as other scaffolds, and the cross bar 3 is directly overlapped with the scaffold plate to provide a construction platform for workers to use.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
