Description

Technical Field

[0001] This utility model relates to the field of construction safety equipment, and in particular to a retractable steel scaffolding. Background Technology

[0002] Steel scaffolding planks are a type of temporary work platform material widely used in construction processes. They are mainly used to build scaffolding systems and provide workers with a safe working surface. Compared with traditional wooden or bamboo scaffolding planks, steel scaffolding planks have higher strength, durability, and safety, and are therefore increasingly favored in modern construction projects.

[0003] For example, the retractable steel scaffolding plank with public announcement number CN220167464U includes a main plank and branch planks. The main plank has guide frames on both sides of its bottom, and the branch planks have guide rods on both sides of their bottom that connect to the corresponding guide frames. The guide rods and guide frames have multiple limiting holes, and bolt and nut assemblies are installed in the limiting holes where the guide rods and guide frames coincide. This invention uses hooks on both sides to attach the steel plank to the scaffolding support rods. However, because the hooks on both sides are fixed, it is inconvenient to adjust them according to the size of the support rods on the scaffolding, making it inflexible in use.

[0004] Therefore, it is necessary to design a rotating ring that can be adjusted according to the size of the support rods on the scaffold, so as to adapt to scaffold support rods of different sizes and use flexible telescopic steel planks. Utility Model Content

[0005] To overcome the shortcomings of existing steel scaffolding planks with fixed hooks on both sides, which are inconvenient to adjust according to the size of the support rods on the scaffolding and lack flexibility in use, this utility model provides a telescopic steel scaffolding plank that can adjust the rotating ring according to the size of the support rods on the scaffolding, making it easy to adapt to scaffolding support rods of different sizes and allowing for flexible use.

[0006] The technical solution is as follows: A retractable steel scaffold plank includes a first steel scaffold plank, a locking knob, a sliding frame, a second steel scaffold plank, a limiting block, and a locking assembly. The first steel scaffold plank has two sections, front and rear. The right side of each first steel scaffold plank is slidably connected to a sliding frame, and the front of each sliding frame is threadedly connected to a locking knob. The left side of each sliding frame is connected to a second steel scaffold plank, and each second steel scaffold plank is in contact with an adjacent first steel scaffold plank. The upper left side of each first steel scaffold plank is connected to a limiting block. Both the front and rear sections of the first and second steel scaffold planks are equipped with locking assemblies that can adapt to scaffold support rods of different sizes.

[0007] As an improvement to the above scheme, all retaining rings are arc-shaped structures.

[0008] As an improvement to the above solution, the locking knobs are all equipped with anti-slip textures.

[0009] As an improvement to the above solution, the locking assembly includes a retaining ring, a housing, retaining teeth, a rotating ring, a locking block, and a spring. The first steel scaffold and the second steel scaffold are connected to the housing at both the front and rear. The upper part of the housing is connected to a retaining ring, and the retaining ring is rotatably and slidably connected to a rotating ring. The lower part of the rotating ring is connected to a retaining tooth, and the middle part of the housing is slidably connected to a locking block. The locking block is connected to the adjacent housing with two springs at the front and rear.

[0010] As an improvement to the above solution, it also includes a pull rod, with pull rods connected to each of the blocks.

[0011] As an improvement to the above solution, it also includes buckles and torsion springs. Buckles are rotatably connected to the front left side of the second steel scaffold, and slots are opened on the rear left side of the second steel scaffold. The buckles are engaged with the adjacent second steel scaffolds through the slots, and torsion springs are connected between the second steel scaffolds and the adjacent buckles.

[0012] This utility model has the following advantages: 1. By rotating the rotating ring along the retaining ring, the rotating ring contacts the support rods on both sides of the scaffold. The adjustment is made according to the thickness of the support rod. Then, the pull rod is released, the spring returns to its original state, and the retaining block moves to the right to reset, so that the retaining block engages with the retaining teeth. This achieves the effect of being able to adjust the rotating ring according to the size of the support rod on the scaffold, which is convenient to adapt to different sizes of scaffold support rods and is flexible in use.

[0013] 2. This utility model pushes the second steel scaffolding plate towards the second steel scaffolding plate that needs to be locked together. The buckle is squeezed by the second steel scaffolding plate and rotates upward. The torsion spring deforms and moves to a certain position. After the torsion spring returns to its original position, it drives the buckle to rotate and reset. This allows the buckle to engage with the second steel scaffolding plate through the slot, achieving the effect of quickly locking the second steel scaffolding plates together. The operation is simple and convenient. Attached Figure Description

[0019] The technical solution will be further described below with reference to specific embodiments. It should be noted that the terms "up," "down," "left," and "right" used in this document refer only to the position of the structure shown in the corresponding drawings. The serial numbers assigned to components in this document, such as "first," "second," etc., are only used to distinguish the described objects and have no sequential or technical meaning.

[0020] A type of retractable steel scaffolding, such as Figure 1 and Figure 4 As shown, it includes a first steel scaffold 2, a locking knob 4, a sliding frame 12, a second steel scaffold 13, a limiting block 14, and a locking assembly. The first steel scaffold 2 has two sections, front and back. The right side of each first steel scaffold 2 is slidably connected to the sliding frame 12. The front of each sliding frame 12 is threadedly connected to the locking knob 4. The locking knob 4 is provided with anti-slip texture for easy gripping. The left side of each sliding frame 12 is connected to the second steel scaffold 13. Each second steel scaffold 13 is in contact with the adjacent first steel scaffold 2. The upper left side of each first steel scaffold 2 is connected to the limiting block 14. Both the first steel scaffold 2 and the second steel scaffold 13 are provided with locking assemblies at the front and back.

[0021] like Figure 1 and Figure 2 As shown, the locking assembly includes a locking ring 1, a housing 3, locking teeth 7, a rotating ring 71, a locking block 8, a spring 9, and a pull rod 10. The first steel scaffold 2 and the second steel scaffold 13 are connected to the housing 3 at both the front and rear. The upper part of the housing 3 is connected to the locking ring 1. The locking ring 1 is an arc-shaped structure, which is convenient for hanging on the scaffold. The locking ring 1 is rotatably and slidably connected to the rotating ring 71. The lower part of the rotating ring 71 is connected to the locking teeth 7. The middle part of the housing 3 is slidably connected to the locking block 8. The locking block 8 is connected to the adjacent housing 3 by two springs 9 at the front and rear. The locking block 8 is connected to the pull rod 10.

[0022] like Figure 1 and Figure 3 As shown, it also includes a buckle 5 and a torsion spring 11. The front left part of the second steel scaffold 13 is rotatably connected to the buckle 5. The rear left part of the second steel scaffold 13 is provided with a slot 6. The buckle 5 is engaged with the adjacent second steel scaffold 13 through the slot 6. The second steel scaffold 13 is connected to the adjacent buckle 5 by a torsion spring 11.

[0023] When using this utility model, firstly, hang the retaining ring 1 on the first steel plank 2 on the two side support rods of the scaffold. Then, move the pull rod 10 to the left, causing the retaining block 8 to move to the left. The spring 9 is compressed and contracted. Then, rotate the rotating ring 71 along the retaining ring 1 so that the rotating ring 71 contacts the two side support rods of the scaffold. Adjust according to the thickness of the support rod. Then, release the pull rod 10, the spring 9 returns to its original state, and causes the retaining block 8 to move to the right to reset, so that the retaining block 8 engages with the retaining tooth 7. Thus, the rotating ring 71 can be adjusted according to the size of the support rod on the scaffold, which is convenient to adapt to different sizes of scaffold support rods and is flexible in use. When the first steel plank 2 and the second steel plank 13 need to be hung on scaffolding of different lengths, the second steel plank 13 can be moved to the left, causing the sliding frame 12 to extend to the left. After being pulled to the limit, it is limited by the limit block 14. Then, the locking knob 4 is turned to lock it. When it is necessary to lock the two second steel planks 13, the second steel plank 13 can be pushed towards the second steel plank 13 that needs to be locked. The buckle 5 will rotate upward under the pressure of the second steel plank 13, and the torsion spring 11 will deform. After moving to a certain position, the torsion spring 11 will return to its original position, causing the buckle 5 to rotate and reset, so that the buckle 5 can be engaged with the second steel plank 13 through the slot 6. This allows for quick locking of the two steel planks 13. The operation is simple and convenient.

[0024] The present application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of the present application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of the present application. Therefore, the content of this specification should not be construed as a limitation of the present application.
