Example 1

A scaffold for decoration comprises two side frames 1 and a standing board 2 arranged between the two side frames 1, wherein each side frame 1 comprises two upright posts 3, two cross rods 4 arranged between the two upright posts 3 and ladders 5 of which two ends are respectively fixed on the two cross rods 4, as shown in figure 1.

Two ends of the standing plate 2 are respectively welded with a retaining ring 6 and are used for suspending two ends of the standing plate 2 on a ladder 5; the height of the standing board 2 can be easily adjusted by suspending the buckle 6 on the step bars of ladders 5 of different heights.

A reinforcing rod 7 is arranged between the upright posts 3 of the two side frames 1; the stability of scaffold arrangement is strengthened.

As shown in fig. 2, in order to solve the problem that "contact area between wheel and ground is too small, can cause the non-artificial slip of wheel, leads to the constructor who stands on the scaffold frame to have the potential safety hazard" mentioned in the background art, the utility model discloses further set up as follows.

The bottom end of the upright post 3 is hinged with an L-shaped combined rod 10 consisting of a first rod 8 and a second rod 9, the end part of the first rod 8 is provided with a circular truncated cone-shaped foot seat 11, the end part of the second rod 9 is provided with a pulley 12, and the bottom end of the upright post 3 is provided with a fixing component for fixing the first rod 8 or the second rod 9.

The specific working principle is that when the scaffold needs to be transported to a customer home for decoration construction, a constructor rotates the L-type combined rod 10 to enable the second rod 9 and the upright post 3 to be in the same straight line, then the second rod 9 and the upright post 3 are fixed through the fixing assembly, so that the pulley 12 is in a working state and convenient to transport, when the scaffold is transported to the customer home, the constructor can rotate the L-type combined rod 10 to enable the first rod 8 and the upright post 3 to be in the same straight line, then the first rod 8 and the upright post 3 are fixed through the fixing assembly, so that the foot seat 11 is in the working state, the contact area between the scaffold and the ground is increased, the stability of the scaffold is improved, and the potential safety hazard caused by the pulley 12 sliding on the tile ground during construction can be eliminated on the premise of considering the transportation advantages of the pulley 12.

As shown in fig. 2 to 4, the bottom end of the upright post 3 is longitudinally provided with a sliding groove 13, the sliding groove 13 is connected with a hinged shaft 14 in a sliding manner, the L-shaped combined rod 10 is hinged to the bottom end of the upright post 3 through the hinged shaft 14, when the hinged shaft 14 is positioned at the top of the sliding groove 13, the end part of the first rod 8 or the second rod 9 is pressed against the end part of the upright post 3, so that the whole weight of the scaffold can be directly transmitted to the first rod 8 or the second rod 9 through the upright post 3, and the condition that the hinged shaft 14 is damaged due to the fact that the hinged shaft 14 bears overlarge weight is avoided.

The end part of the first rod 8 far away from the foot seat 11 and the end part of the second rod 9 far away from the pulley 12 are both provided with hemispherical grooves 15, and the bottom end of the upright post 3 is provided with a hemispherical lug 16 which is in splicing fit with the grooves 15; the contact area between the first rod 8 or the second rod 9 and the end of the upright 3 can be increased, and the bearing pressure of the end of the first rod 8 or the second rod 9 can be reduced.

The fixing assembly in the embodiment comprises two rotating plates 17 which are respectively positioned on two sides of the upright post 3, the rotating plates 17 are hinged to the upright post 3, the planes of the two rotating plates 17 are the same as the planes of the L-type combined rods 10 when rotating, the rotating plates 17 can partially abut against the surfaces of the first rod 8 or the second rod 9 after rotating, when the rotating plates 17 rotate to partially abut against the surfaces of the first rod 8 or the second rod 9, the first rod 8 or the second rod 9 can be prevented from rotating artificially, when the rotating plates 17 rotate to completely abut against the side walls of the upright post 3, the fixing effect can be relieved, and the L-type combined rod 10 can rotate freely.

The rotating plate 17 is rotatably connected with the upright post 3 through a screw 18; when the rotating plate 17 rotates to a proper position and the screw 18 is screwed, the abutting force between the rotating plate 17 and the first rod 8 or the second rod 9 can be increased, and the rotating plate 17 is prevented from rotating under the non-artificial condition, so that the fixing function is released.

Example 2

The difference from embodiment 1 is in the fixing member.

As shown in fig. 5 and 6, the fixing assembly in this embodiment includes a first insertion hole 19 opened at the bottom end of the upright 3, a second insertion hole 20 opened at the end of the first rod 8, and a third insertion hole 21 opened at the end of the second rod 9, an insertion rod 22 is inserted and fitted in the first insertion hole 19, and when the insertion rod 22 passes through the second insertion hole 20, the foot seat 11 is in an operating state; when the insertion rod 22 passes through the third insertion hole 21, the pulley 12 is in a working state; the fixing of the upright post 3 and the first rod 8 can be realized by allowing the insertion rod 22 to simultaneously pass through the first insertion hole 19 and the second insertion hole 20, and the fixing of the upright post 3 and the second rod 9 can be realized by allowing the insertion rod 22 to simultaneously pass through the first insertion hole 19 and the third insertion hole 21.
