Description

Technical Field

[0001] This utility model relates to the field of scaffolding technology, and in particular to a quick-locking fastener for scaffolding crossbars. Background Technology

[0002] Existing scaffolding horizontal bar couplers mostly rely on bolt fastening, requiring the use of tools such as electric wrenches to tighten each bolt individually during installation. This process is cumbersome, and the tools are inconvenient to carry and the operation is time-consuming, severely impacting construction efficiency. Furthermore, bolts are prone to loosening due to vibration over long-term use, leading to decreased stability of the coupler connection and posing safety hazards. Disassembly requires reversing the bolts to loosen them, which is also time-consuming and laborious. Repeated disassembly and assembly can cause bolt stripping, reducing the coupler's reusability and negatively impacting its use. To address the shortcomings of existing technologies, we propose a quick-locking coupler for scaffolding horizontal bars. Utility Model Content

[0003] The main purpose of this utility model is to provide a quick-locking fastener for scaffold crossbars, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A quick-locking coupler for scaffold crossbars includes a first mounting coupler, a second mounting coupler, and multiple mounting components installed between the first and second mounting couplers. Both the first and second mounting couplers have insertion slots on one end surface. Insertion blocks are fixedly connected to both the upper and lower ends of each mounting component. Two insertion boxes are symmetrically fixed to the outer surface of the second mounting coupler, and the surface of each insertion box has a first locking groove. Two insertion plates are symmetrically fixed to the outer surface of the first mounting coupler. The inner cavity of each insertion plate has a first spring and a first limiting plate, and one end of the first limiting plate is fixedly connected to a first locking block.

[0006] A circular fixing block is fixedly connected to one end of the first mounting fastener and the second mounting fastener, as well as one side of the mounting component. Two rectangular slots are symmetrically opened in the circular fixing block. A second spring and a second limiting plate are provided in the rectangular slots. A second snap-fit ​​block is fixedly connected to one end of the second limiting plate. A scaffolding rod is sleeved on the outer surface of the circular fixing block. Two second snap-fit ​​slots are symmetrically opened on the outer surface of the scaffolding rod.

[0007] Preferably, the shape of the plug block matches the shape of the plug slot, the plug block can be completely embedded in the plug slot to form a stable plug-in fit, and the outer surface of the plug block fits the inner wall of the plug slot without obvious loosening.

[0008] Preferably, the end of the first snap-fit ​​block away from the first limiting plate is provided with a guide slope, which is adapted to the opening of the first snap-fit ​​groove. The first spring can drive the first snap-fit ​​block to snap into the first snap-fit ​​groove, and the first limiting plate can slide linearly along the inner cavity of the plug-in plate without detaching from the plug-in plate.

[0009] Preferably, the outer surface of the circular fixing block is in close contact with the inner wall of the scaffold pole, the second locking block can be popped out and locked into the second locking groove under the action of the second spring, and the second limiting plate can slide along the inner wall of the rectangular groove and limit the movement range of the second locking block.

[0010] Preferably, the end of the second snap-fit ​​block away from the second limiting plate is provided with a guide slope, and the second snap-fit ​​block is adapted to the second snap-fit ​​groove. The two ends of the second spring are respectively fixedly connected to the inner wall of the rectangular groove and the second limiting plate, which can drive the second snap-fit ​​block to be fully snapped into the second snap-fit ​​groove.

[0011] Preferably, the number of mounting components is four, and they are arranged in a ring array between the first mounting fastener and the second mounting fastener, with equal spacing between adjacent mounting components.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This quick-locking coupler for scaffolding crossbars features a design that allows for rapid installation without additional tools through the precise fit between the plug and slot and the spring-driven automatic locking mechanism. During installation, the plug inserts into the slot to form a preliminary stable connection, and the locking block automatically engages with the slot under the action of the spring to complete the lock. This significantly reduces the cumbersome steps of traditional coupler bolt tightening, greatly shortens installation time, and is suitable for scenarios with tight construction schedules. It reduces the labor intensity of workers while improving safety during installation.

[0014] This scaffolding crossbar quick-locking coupler can be easily disassembled by simply pressing the locking block, eliminating the need for complicated tools and saving disassembly time and labor costs. Furthermore, the tightly fitting plug-in and snap-fit ​​connections between components ensure a stable and reliable locking state, reducing the risk of loosening during use and improving the overall stability of the scaffolding structure. In addition, the components can be repeatedly disassembled and reassembled, allowing for multiple uses, reducing material waste and procurement costs, and extending the coupler's service life.

[0020] 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.

[0021] Example 1, as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, a quick-locking fastener for scaffold crossbars involves aligning four mounting pieces 3 in a circular array with the corresponding positions of the first mounting fastener 1 and the second mounting fastener 2. The insertion blocks 5 at the upper and lower ends of the mounting pieces 3 are aligned with the insertion slots 4 on the surfaces of the first and second mounting fasteners 1 and 2. Pressure is applied perpendicular to the fastener surface until the insertion blocks 5 are fully embedded in the insertion slots 4. At this point, the outer surface of the insertion blocks 5 is tightly fitted to the inner wall of the insertion slots 4 without significant loosening, completing the initial stable connection between the mounting pieces 3 and the first and second mounting fasteners. Next, the first and second mounting fasteners 1 and 2 are pushed closer together, causing the two insertion plates 8 on the outer surface of the first mounting fastener 1 to be inserted into the two insertion boxes 6 on the outer surface of the second mounting fastener 2. During insertion, the first locking block 11 retracts into the inner cavity of the insertion plate 8, simultaneously compressing the first spring 9. When the insertion plates 8 are fully... After the plug-in box 6 is inserted, the first spring 9 returns to its original shape, pushing the first limiting plate 10 to cause the first locking block 11 to pop out and lock into the first locking groove 7, thus completing the locking of the first mounting fastener 1 and the second mounting fastener 2, forming a complete fastener main structure. Then, one end of the scaffold pole 17 is aligned with the circular fixing block 12 on one side of the first mounting fastener 1, the second mounting fastener 2 and the mounting part 3, and the scaffold pole 17 is pushed axially. During the pushing process, the inner wall of the scaffold pole 17 presses the second locking block 16 on the circular fixing block 12. The second locking block 16 retracts into the rectangular groove 13, compressing the second spring 14. When the second locking groove 18 on the scaffold pole 17 corresponds to the position of the second locking block 16, the second spring 14 returns to its original shape, pushing the second limiting plate 15 to cause the second locking block 16 to pop out and lock into the second locking groove 18, thus achieving the locking of the scaffold pole 17 and the fastener.

[0022] Example 2, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick-locking fastener for scaffold crossbars is described. During disassembly, first press the guide slope end of the first locking block 11 to retract it into the inner cavity of the insertion plate 8, compressing the first spring 9 until the first locking block 11 disengages from the first locking groove 7. Then, pull the first mounting fastener 1 and the second mounting fastener 2 away from each other, causing the insertion plate 8 to be pulled out of the insertion box 6. Next, pull the mounting piece 3 in a direction perpendicular to the fastener surface to disengage the insertion block 5 from the insertion groove 4, completing the disassembly of the fastener body. For disassembly of the scaffold pole 17, press the guide slope end of the second locking block 16 to retract it into the rectangular groove 13, compressing the second spring 14 until the second locking block 16 disengages from the second locking groove 18. Then, pull the scaffold pole 17 axially to remove it from the circular fixing block 12, thus completing the disassembly.
