Description

Technical Field

[0001] This utility model relates to the field of steel pipe scaffolding technology, and in particular to a ring-type swivel coupler for steel pipe scaffolding that can be quickly inserted and removed. Background Technology

[0002] Swivel couplers are an indispensable connecting element in steel pipe scaffolding. They can be quickly inserted and removed, flexibly adapting to the connection needs between two parallel or oblique members, ensuring the stability and safety of the scaffolding. They are widely used in construction, machinery manufacturing, aerospace and other fields.

[0003] Chinese Patent Publication No. CN221609467U discloses a ring-type rotating coupler for steel pipe scaffolding; it includes a connecting ring and two identical fastening components. The first fastening component includes a first fixed arc plate, a first rotating shaft, and a first movable arc plate. The first fixed arc plate has a first arc-shaped portion, one end of which is a first rotating portion, and the other end is a first fastening portion. The outer side wall of the first fastening portion has multiple first fastening grooves, and the inner side wall of the first fastening portion is connected to multiple first fasteners. The first movable arc plate has a second arc-shaped portion, one end of which is a second rotating portion, and the other end is a second fastening portion. The outer side wall of the second fastening portion has multiple second fastening grooves, and the connecting ring is nested between the first and second fastening grooves. It retains all the functions of existing rotating couplers, and can realize multiple connecting rings and bolt fastening, providing multiple protections and reducing safety risks.

[0004] The device described in the aforementioned literature fixes the steel pipe by pressing the connecting ring into the locking groove. However, in practical applications, pressing the connecting ring requires a certain amount of strength and skill, especially when scaffolding needs to be erected or dismantled quickly. This operation method may increase the labor intensity of construction workers. If the fit between the connecting ring and the locking groove is not tight enough or there are design defects, the connecting ring may get stuck or fail to be fully pressed into the locking groove during the pressing process. Furthermore, because the fit between the connecting ring and the locking groove is relatively tight, it may be difficult to disassemble and replace the pipe when a fault or wear occurs, increasing the difficulty of maintenance.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Example 1

[0026] like Figure 1 and Figure 2As shown, a quick-plugging ring-type steel pipe scaffolding swivel coupler includes two fixing components 1, which are symmetrically arranged. Each fixing component 1 has a ring-type component 2 rotatably connected to its right side. Each fixing component 1 has a connecting component 3 fixedly connected to its side that is close to each other. The two connecting components 3 are fixedly connected.

[0027] As shown in the figure, the fixing component 1 includes an arc plate 11, an arc plate 2 12 is rotatably connected to the left side of the arc plate 11, a slot 13 is provided on the right side of the arc plate 2 12, and several circular grooves 14 are provided on the side of the arc plate 11 and the arc plate 2 12 that are close to each other. Springs 15 are fixedly connected in the several circular grooves 14, and several springs 15 located on the same side are fixedly connected to a clamping plate 16.

[0028] Spring 15 is elastic and can provide continuous clamping force when clamping the steel pipe with clamp 16. When the steel pipe undergoes slight displacement due to force or vibration, spring 15 can automatically adjust the clamping force to ensure that the steel pipe is always firmly clamped, which improves the stability and reliability of the fastener in complex construction environments and can adapt to steel pipes of different diameters, thus enhancing the versatility of the fastener.

[0029] like Figure 3 As shown, the ring buckle assembly 2 includes an upper rod 21 located on the upper side of the slot 13. Connectors 22 are fixedly connected to both sides of the lower end of the upper rod 21. Two movable parts 23 are slidably connected to the middle of the two connectors 22. The two movable parts 23 are symmetrically arranged. The lower ends of the two connectors 22 are fixedly connected to a lower rod 24. The lower rod 24 is rotatably connected to the right side of the arc plate 11.

[0030] like Figure 4 As shown, the connector 22 includes a cylindrical shell 221 located on the lower side of the upper rod 21. A fixing plate 222 is fixedly connected to the middle of the inner surface of the cylindrical shell 221. Sliding grooves 223 are provided on both sides of the inner surface of the cylindrical shell 221.

[0031] like Figure 4 As shown, the movable component 23 includes a slide rod 231 slidably connected to one side of the fixed plate 222. A fixing ring 232 is fixedly connected to the middle of the outer surface of the slide rod 231. A spring 233 is fixedly connected to the fixing ring 232 and the inner surface of the cylindrical shell 221. The spring 233 is sleeved on the outer surface of the slide rod 231. A locking block 234 is fixedly connected to the end of the outer surface of the slide rod 231 away from the spring 233. The locking block 234 is slidably connected in a sliding groove 223 that is close to each other. The end of the slide rod 231 away from the locking block 234 passes through the cylindrical shell 221 and is slidably connected to the cylindrical shell 221.

[0032] Furthermore, the two sliding rods 231 penetrating the upper side of the cylindrical shell 221 are fixedly connected to the upper rod 21, and the two sliding rods 231 penetrating the lower side of the cylindrical shell 221 are fixedly connected to the lower rod 24.

[0033] In this embodiment, the steel pipe is placed on the upper side of the clamping plate 16, and the second arc plate 12 is rotated so that the first arc plate 11 and the second arc plate 12 gradually approach each other. The first spring 15 pushes the clamping plate 16 to hold the steel pipe and fix it. Then, the lower rod 24 is rotated, and the lower rod 24 drives the connecting piece 22 and the upper rod 21 to move. The upper rod 21 is moved into the slot 13. The moving piece 23 can be adjusted according to the distance between the first arc plate 11 and the second arc plate 12 so that the upper rod 21 is stably located in the slot 13.

[0034] When the distance between arc plate 11 and arc plate 22 is large, the slot 13 and arc plate 11 together push the upper rod 21 and lower rod 24 to move away from each other, thereby causing the slide rod 231 to slide within the fixed plate 222. When the distance between arc plate 11 and arc plate 22 is small, the spring 233 pushes the fixed ring 232 and slide rod 231 to move towards the fixed plate 222, causing the slide rod 231 to slide within the connector 22, thereby pulling the upper rod 21 and lower rod 24 to move closer to each other. By adjusting the moving part 23, the ring buckle assembly 2 can fix arc plate 11 and arc plate 22, thereby fixing the steel pipe.

[0035] Example 2

[0036] Based on Embodiment 1, this embodiment adds a connecting component 3, which allows the two steel pipes to rotate, adjusting the angle and spacing between them, thus improving the flexibility of the device.

[0037] like Figure 5 As shown, the connecting assembly 3 includes a connecting housing 31 fixedly connected to the lower side of the arc plate 11. A sliding rod 32 is slidably connected to the middle of the lower side of the connecting housing 31. A limiting plate 33 is fixedly connected to one end of the sliding rod 32 that is close to the arc plate 11. A spring 34 is fixedly connected to the limiting plate 33 and the bottom wall of the inner surface of the connecting housing 31. The spring 34 is sleeved on the outer surface of the sliding rod 32.

[0038] Specifically, the two slide rods are fixedly connected at 32.

[0039] In this embodiment, both connecting housings 31 are movably connected to the slide rod 32, thereby allowing the steel pipe to be rotated and its tilt angle to be flexibly adjusted. At the same time, the connecting housings 31 and the slide rod 32 are slidably connected, allowing the distance between the two fixed components 1 to be adjusted, thereby achieving the adjustment of the distance between the two steel pipes.

[0040] The working principle of this utility model is as follows: First, the steel pipe is placed on the upper side of the clamping plate 16, and the second arc plate 12 is rotated so that the first arc plate 11 and the second arc plate 12 gradually approach each other. The first spring 15 pushes the clamping plate 16 to hold the steel pipe and fix it. Then, the lower rod 24 is rotated, and the lower rod 24 drives the connecting piece 22 and the upper rod 21 to move, moving the upper rod 21 into the slot 13. The moving piece 23 can be adjusted according to the distance between the first arc plate 11 and the second arc plate 12 so that the upper rod 21 is stably located in the slot 13.

[0041] When the distance between arc plate 11 and arc plate 22 is large, the slot 13 and arc plate 11 together push the upper rod 21 and lower rod 24 to move away from each other, thereby causing the slide rod 231 to slide within the fixed plate 222. When the distance between arc plate 11 and arc plate 22 is small, the spring 233 pushes the fixed ring 232 and slide rod 231 to move towards the fixed plate 222, causing the slide rod 231 to slide within the connector 22, thereby pulling the upper rod 21 and lower rod 24 to move closer to each other. By adjusting the moving part 23, the ring buckle assembly 2 can fix the arc plate 11 and arc plate 22, thereby fixing the steel pipe.

[0042] Both connecting housings 31 are movably connected to the slide rod 32, which allows the steel pipe to be rotated and its tilt angle to be flexibly adjusted. At the same time, the connecting housings 31 and the slide rod 32 are slidably connected, which allows the distance between the two fixed components 1 to be adjusted, thereby achieving the adjustment of the distance between the two steel pipes.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
