[0001] This utility model relates to the field of scaffolding technology, and in particular to a scaffolding that can be quickly assembled and disassembled. Background Technology

[0002] Scaffolding is a temporary building support structure commonly used in construction projects, primarily to provide workers with a safe working platform. It is widely used in construction projects, maintenance, and cleaning operations.

[0003] Existing scaffolding is usually connected using pipe couplers. During installation and dismantling, bolts are needed for tightening. The process of installing and removing bolts and nuts is slow and inconvenient.

[0004] Therefore, this application provides a quick-assembly and disassembly scaffolding to overcome the shortcomings of the prior art. Summary of the Invention

[0005] The purpose of this invention is to solve the problem that existing scaffolding is slow to assemble and disassemble and inconvenient to disassemble.

[0006] This utility model provides a quick-assembly and disassembly scaffold, including uprights, horizontal bars one and horizontal bars two. The uprights are arranged vertically, and there are at least four uprights. Horizontal bars one and two are arranged horizontally between the uprights. Horizontal bars one is arranged laterally, and horizontal bars two are arranged longitudinally. A fixing plate is fixed to the outer wall of the upright. Both ends of horizontal bars one and two are fixed with snap-fit ​​parts. The snap-fit ​​parts can be inserted into the fixing plate and detachably connected to the fixing plate.

[0007] As a preferred technical solution, the fixing plate has a slot 1, the inner side wall of the slot 1 is fixedly connected to the outer side wall of the upright, and the fixing plate has a number of evenly distributed slots 2, which are located around the outer side of the slot 1. There are 4 slots 2, and the opening shape of the slots 2 is preferably circular, elliptical, rectangular or strip-shaped. The slots 2 are used for insertion with the snap-fit ​​component.

[0008] As a preferred technical solution, the snap-fit ​​component includes a connecting block, one side of which is fixedly connected to the end of crossbar one or crossbar two. A connecting plate one is fixed to the bottom of the connecting block. The thickness of the connecting block is not less than the thickness of the connecting plate one, and the width of the connecting block is not less than the width of the connecting plate one. Anti-detachment mechanisms are provided on both the left and right sides of the connecting plate one, one of which is located on the left side wall of the connecting plate one near the rear, and the other is located on the right side wall of the connecting plate one near the front.

[0009] As a preferred technical solution, the width of the connecting plate is variable and symmetrical on both the front and back sides, gradually narrowing from the top to the bottom.

[0010] As a preferred technical solution, the anti-fall-off mechanism includes a slot, the slot being an inclined V-shape, a rotating shaft being rotatably connected in the slot, and a connecting plate two being fixed on the rotating shaft, the connecting plate two being disposed in the slot.

[0011] As a preferred technical solution, the maximum angle of the second connecting plate is no greater than 180 degrees, and the maximum width between the two second connecting plates is greater than the maximum width of the connecting block.

[0012] The beneficial effects of the quick-assembly and disassembly scaffolding provided by this utility model are:

[0013] This utility model uses a fixing plate and a snap-fit ​​component to complete the connection by inserting the connecting plate into the slot 2. By moving the crossbar upward, the connecting plate can be disassembled by detaching it from the slot 2. The assembly and disassembly are simple and convenient, and can be quickly installed and disassembled.

[0014] By setting up two independent anti-fall-off mechanisms, the two do not affect each other. Due to the special groove structure, the second connecting plate can unfold under its own weight without the action of external force, preventing workers from accidentally pulling up the crossbar when going up or down the scaffold or moving materials. It can also prevent the snap-fit ​​parts from accidentally falling off the fixed plate, thus improving safety. Attached Figure Description

[0023] To make the technical means, technical features, utility model purpose and technical effects of this utility model easy to understand, the present utility model will be further described below with reference to specific illustrations. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.

[0024] Example 1

[0025] As shown in Figures 1 to 7: A quick-assembly and disassembly scaffold includes at least uprights 1, horizontal bars 3 and horizontal bars 4. The uprights 1 are vertically arranged, and there are at least 4 uprights 1. The horizontal bars 3 and horizontal bars 4 are horizontally arranged between the uprights 1. The horizontal bars 3 are arranged laterally, and the horizontal bars 4 are arranged longitudinally. A fixing plate 2 is fixed on the outer wall of the uprights 1. Both ends of the horizontal bars 3 and horizontal bars 4 are fixed with snap-fit ​​pieces 5. The snap-fit ​​pieces 5 can be inserted into the fixing plate 2 and are detachably connected to the fixing plate 2.

[0026] As shown in Figures 1 and 2: The fixing plate 2 has a slot 21, the inner side wall of the slot 21 is fixedly connected to the outer side wall of the upright 1. The fixing plate 2 has a number of evenly distributed slots 22, which are located around the outer side of the slot 21. There are 4 slots 22. The opening shape of the slots 22 is preferably circular, elliptical, rectangular or strip-shaped. The slots 22 are used to insert with the snap-fit ​​component 5.

[0027] As shown in Figures 3 to 7: The snap-fit ​​component 5 includes a connecting block 51. One side of the connecting block 51 is fixedly connected to the end of the first crossbar 3 or the second crossbar 4. A connecting plate 52 is fixed to the bottom of the connecting block 51. The thickness of the connecting block 51 is not less than the thickness of the connecting plate 52, and the width of the connecting block 51 is not less than the width of the connecting plate 52. Anti-detachment mechanisms 53 are provided on both the left and right sides of the connecting plate 52. One of them is located on the left side wall of the connecting plate 52 near the rear, and the other is located on the right side wall of the connecting plate 52 near the front. The two anti-detachment mechanisms 53 do not affect or interfere with each other.

[0028] The width of the connecting plate 52 is variable and symmetrical on both the front and back sides. The width gradually narrows from the top to the bottom. The connecting plate 52 can also be composed of two parts, the upper part of which gradually narrows from the top to the bottom, while the width of the lower part remains unchanged and is consistent with the width of the narrowest part at the top.

[0029] The anti-fall-off mechanism 53 includes a slot 54, which is an inclined V-shape. A rotating shaft 55 is rotatably connected in the slot 54. A connecting plate 2 56 is fixed on the rotating shaft 55. The connecting plate 2 56 is located in the slot 54 and can rotate a certain angle in the slot 54.

[0030] As shown in Figure 7: When there is no external force, due to the gravity of the connecting plate 56 itself, the connecting plate 56 rotates around the pivot 55 until it abuts against the bottom edge of the slot 54, as shown in Figure 7. That is, part of the connecting plate 56 is outside the connecting plate 52. The maximum angle of the connecting plate 56 is no more than 180 degrees. The maximum width between the two connecting plates 56 is greater than the width of the connecting block 51, which can prevent the snap-fit ​​5 from detaching from the fixing plate 2 and increase the safety of the equipment.

[0031] Working method: Insert the snap-fit ​​pieces 5 at both ends of crossbar 3 and crossbar 4 into the slot 22 of the fixing plate 2. Connecting plate 52 is snapped into the fixing plate 2 through slot 22. Use a hammer to gently tap it several times to make the snap-fit ​​pieces 5 and slot 22 securely connected. Then check whether connecting plate 56 is unfolded (as shown in Figure 7). If it is not unfolded, move it by hand to make it as shown in Figure 7. When it needs to be removed, first retract connecting plate 56 back into slot 54, then use a hammer to tap crossbar 3 and crossbar 4 upwards to loosen the snap-fit ​​pieces 5 from slot 22. Then lift crossbar 3 and crossbar 4 upwards to disengage the snap-fit ​​pieces 5 from slot 22.
