[0031] Please refer to Figures 1-5 The utility model provides a technical scheme:

[0032] In various types of construction, equipment installation, indoor and outdoor decoration and other high-altitude work scenes, a scaffold capable of being quickly assembled and stable in structure is very important. The specific implementation of a quickly assembled scaffold will be introduced below, including the connection relationship of various components and working principle.

[0033] The core support structure of the scaffold is composed of two main frame bodies 1. The main frame body 1 is made of high-strength metal material and can bear the weight of workers, construction tools and materials after processing and detection. The main frame body 1 is rotatably connected to the support frame 2 on one side through a rotating shaft. The rotating shaft is smooth in surface after processing, which can reduce friction and make the support frame 2 rotate flexibly. The other end of the support frame 2 is rotatably connected to the sliding sleeve 3. The sliding sleeve 3 can slide on the other main frame body 1. The inner diameter of the sliding sleeve 3 is adapted to the outer diameter of the main frame body 1 to ensure smooth sliding. The support frames 2 on the two main frame bodies 1 are hingedly connected to each other through a hinge shaft to form a scissor mechanism, which can change shape with the main frame body 1 to realize the expansion and contraction of the scaffold.

[0034] The crossbar 4 is welded on the main frame body 1 to ensure that the connection between the crossbar 4 and the main frame body 1 can withstand external force. The crossbar 4 has a rotating connecting piece, and the working panel 5 is rotatably arranged on the crossbar 4 through the rotating connecting piece. The working panels 5 on the two main frame bodies 1 are hingedly connected to each other through a hinge shaft. When expanded or contracted, the working panel 5 rotates with the main frame body 1 and the crossbar 4, and after expansion, the working panels 5 are spliced into a working platform.

[0035] In order to make the scaffold stable after unfolding, the main frame body 1 is provided with a positioning assembly 6. The positioning assembly 6 comprises a fixed rod 61 in the main frame body 1. The fixed rod 61 is sleeved with a positioning block 62, and the two are gap-fitted, and the positioning block 62 can freely slide. The fixed rod 61 is further provided with a spring 63, one end of which abuts against the positioning block 62, and the other end abuts against the main frame body 1. The positioning block 62 is provided with an inclined block 64 and a pressing block 65, and the inclined surface of the inclined block 64 can make the positioning block 62 slide. The sliding sleeve 3 is provided with a positioning hole 66 matched with the inclined block 64, and the inclined block 64 is clamped into the positioning hole 66 to position the sliding sleeve 3 and fix the main frame body 1.

[0036] The locking assembly 7 on the working panel 5 ensures its stability. The locking assembly 7 comprises a fixed frame 71 fixed on one working panel 5 by bolts, and the fixed frame 71 is provided with a sliding groove in which a positioning pin 72 can slide. The positioning pin 72 is provided with a positioning piece 73, and is sleeved with a return spring 74, one end of which abuts against the positioning piece 73, and the other end abuts against the fixed frame 71. The other working panel 5 is provided with a positioning sleeve 75, and the positioning pin 72 is inserted into the positioning sleeve 75 to lock the working panel 5.

[0037] The main frame body 1 is bolted with a handle 8, and the handle 8 is pasted with a non-slip pad 9, and the non-slip pad 9 is provided with non-slip lines 10 to increase friction and prevent hands from slipping. The main frame body 1 is welded with cross-distributed reinforcing rods 11 to enhance the structural strength of the main frame body 1. The bottom of the main frame body 1 is installed with universal wheels 12 through shaft pins, and the universal wheels 12 are flexible in rotation and good in carrying capacity, facilitating the movement of the scaffold.

[0038] The scaffold is provided with a detachable ladder 13, and the ladder 13 is provided with hooks 14 which can be hung on the cross bars 4 and the reinforcing rods 11. There are also detachable guardrails 15, and the main frame body 1 is provided with connecting barrels 16, and the two ends of the guardrails 15 can be inserted into the connecting barrels 16 and sleeved between the two main frame bodies 1, thereby providing safety protection and reinforcing the main frame body 1. The cross bars 4 and the main frame body 1 are welded with inclined reinforcing columns 17 to enhance the connection strength between the cross bars 4 and the main frame body 1 and improve the carrying capacity of the working panel 5. One main frame body 1 is provided with a rotating locking connecting rod 19, and the other main frame body 1 is provided with a locking pin 20 matched therewith, so that the main frame body 1 can be fixed during storage and transportation. The working panel 5 is provided with a plurality of weight-reducing holes 18 for reducing the weight of the working panel 5.

[0039] Working principle:

[0040] When the scaffold is used, the operator first releases the locking connecting rod 19. The handle 8 on the main frame body 1 is held, and the two groups of main frame bodies 1 are pulled apart in the opposite direction, and the universal wheels 12 at the bottom of the main frame body 1 rotate to reduce resistance. When the main frame body 1 is pulled apart, the scissors mechanism composed of the support frames 2 is actuated. Since one end of the support frame 2 is rotationally connected with the main frame body 1, and the other end is rotationally connected with the sliding sleeve 3, the support frame 2 rotates around the rotation axis while driving the sliding sleeve 3 to slide on the main frame body 1, and the main frame body 1 is stably unfolded.

[0041] Meanwhile, the working panel 5 on the two main frames 1 is unfolded with the main frames 1 and the cross bar 4. Continue to pull the main frames 1, the positioning pin 72 interferes with the positioning sleeve 75, the operator pulls the positioning pin 72, continues to pull the main frames 1 to align the positioning pin 72 with the positioning sleeve 75, releases the positioning pin 72, and the reset spring 74 pushes it back to insert into the positioning sleeve 75, fixing the working panel 5.

[0042] When the positioning pin 72 cooperates with the positioning sleeve 75, the sliding sleeve 3 slides close to the inclined block 64, and the inclined block 64 guides the positioning block 62 to slide along the fixed rod 61 and compress the spring 63. After the sliding sleeve 3 is in place, the spring 63 pushes the positioning block 62 to make the inclined block 64 clamped into the positioning hole 66, locking the sliding sleeve 3 and the main frame 1.

[0043] After the above operation is completed, the operator inserts the guardrail 15 into the connecting barrel 16 at both ends, the guardrail 15 provides protection and reinforces the main frame 1. Finally, the ladder 13 is hung on the cross bar 4 and the reinforcing rod 11 through the hook 14, and the work is done through the ladder 13. After the work is completed, the ladder 13 is removed in the reverse order, the guardrail 15 is pulled out, the positioning assembly 6 and the working panel 5 are unlocked, the main frame 1 is folded, and the locking link 19 and the locking pin 20 are locked for storage and transportation.

[0044] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
