Abstract
Description
Technical Field
[0001] This utility model relates to the field of building technology, and in particular to a scaffolding connection fastener anti-loosening component. Background Technology
[0002] Scaffolding and scaffolding fasteners are indispensable auxiliary tools in construction. Scaffolding is a temporary supporting structure erected during construction, providing workers with a safe and stable standing and operating space for high-altitude operations. Fasteners are the core components of scaffolding, used to fix the connections between steel pipes to ensure the stability and safety of the overall structure.
[0003] A search revealed that Chinese patent CN210508345U discloses a scaffolding connecting fastener. This fastener addresses the issue that during scaffolding installation or dismantling, the workload is heavy, and prolonged use of tools can cause wrist fatigue for workers, resulting in low installation or dismantling efficiency. Therefore, it pre-tightens the fastener with bolts and then secures it a second time by rotating the handle. This method is relatively time-saving and labor-saving, offering advantages such as time efficiency, reduced labor costs, and lower costs.
[0004] While the aforementioned scaffolding couplers facilitate bolt rotation during use, existing technologies typically employ studs and nuts to lock the couplers in place. However, scaffolding is prone to vibration due to worker movement during use, and the locked nuts are not easily restrained. As the scaffolding vibrates synchronously with the couplers over a long period, the unrestrained nuts may wobble and loosen, potentially causing the fixed steel pipes to loosen, thus increasing the danger of using scaffolding. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a scaffolding connection fastener anti-loosening component.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a scaffolding connecting fastener anti-loosening component, comprising a fastener body, a stud fixedly connected to one side of the fastener body, a nut threadedly connected to the external thread of the stud, connecting ears fixedly connected to both sides of the nut, and a push-tightening component provided on one side of the fastener body;
[0007] The push-tightening assembly includes a fixing frame, which is fixedly connected to one side of the fastener body. A fixing shell is fixedly connected to one side of the fixing frame. A plurality of through holes are opened on one side of the fixing shell, and a connecting rod is slidably connected inside the through holes.
[0008] As a further description of the above technical solution:
[0009] One end of each of the multiple connecting rods is fixedly connected to a connecting block, and the other end of each of the multiple connecting rods is fixedly connected to a limit post.
[0010] As a further description of the above technical solution:
[0011] The limiting post has a through groove inside, and multiple slots are provided on one side of the limiting post.
[0012] As a further description of the above technical solution:
[0013] One side of the limiting post is fixedly connected to a plurality of first springs, and the plurality of first springs are fixedly connected to the inner wall of the fixed shell.
[0014] As a further description of the above technical solution:
[0015] The upper surface of the fixed shell is provided with a positioning component, the positioning component including a mounting shell, and the upper surface of the mounting shell has multiple through holes.
[0016] As a further description of the above technical solution:
[0017] A fixing rod is slidably connected inside the through hole. One end of the fixing rod is fixedly connected to a connecting frame. A mounting frame is fixedly connected to the lower surface of the connecting frame. An arc-shaped plate is fixedly connected to the lower surface of the mounting frame.
[0018] As a further description of the above technical solution:
[0019] Two positioning blocks are fixedly connected to the lower surface of the arc-shaped plate, and multiple second springs are fixedly connected to the upper surface of the mounting bracket. The multiple second springs are fixedly connected to the inner wall of the mounting shell, and positioning grooves are respectively opened on the upper surfaces of the two connecting rods and the connecting blocks.
[0020] This utility model has the following beneficial effects:
[0021] 1. This utility model, through the setting of the push-tightening component, uses the slot to lock onto the outside of the connecting ear, which facilitates fixing the position of the nut through the connecting ear. At the same time, with the push force of the first spring, the limiting post squeezes the nut, thereby limiting the nut and reducing the phenomenon of displacement and rotation of the nut outside the stud when the fastener vibrates. This helps to improve the fastening of the fastener and enhance the safety of scaffolding use.
[0022] 2. By setting up a positioning component, this utility model utilizes the engagement of the positioning block and the positioning groove to facilitate the positioning of the movement position of the limiting post. After the limiting post is tightened on the nut, the positioning block engages with the positioning groove on the connecting block to position the limiting post, thereby further improving the limiting effect on the nut and reducing the phenomenon of displacement of the limiting post.

Detailed Implementation
[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] As attached Figure 1-7 As shown, one embodiment of this utility model is provided: a scaffolding connection fastener anti-loosening component, including a fastener body 1, a stud 2 fixedly connected to one side of the fastener body 1, a nut 3 connected to the external thread of the stud 2, and connecting ears 4 fixedly connected to both sides of the nut 3 to facilitate the tightening of the nut 3. A push-tightening component is provided on one side of the fastener body 1.
[0034] The push-tightening assembly includes a fixing frame 5, which is fixedly connected to one side of the fastener body 1. A fixing shell 6 is fixedly connected to one side of the fixing frame 5 to provide space for the retraction of the limiting post 9. Multiple through holes are opened on one side of the fixing shell 6, and a connecting rod 7 is slidably connected inside the through holes for connecting the limiting post 9.
[0035] As attached Figure 5 As shown, one end of the multiple connecting rods 7 is fixedly connected to a connecting block 8, and the other end of the multiple connecting rods 7 is fixedly connected to a limiting post 9. The limiting post 9 has a through groove 10 inside for the passage of the stud 2. The limiting post 9 has multiple slots 11 on one side. The slots 11 are arranged relatively densely to facilitate the engagement and limiting of the connecting ear 4 in different directions.
[0036] As attached Figure 4 As shown, a plurality of first springs 12 are fixedly connected to one side of the limiting post 9. The plurality of first springs 12 are fixedly connected to the inner wall of the fixed shell 6, which pushes the limiting post 9, so that the limiting post 9 can push one side of the nut 3.
[0037] As attached Figure 6 As shown, a positioning assembly is provided on the upper surface of the fixed shell 6. The positioning assembly includes a mounting shell 13. Multiple through holes are provided on the upper surface of the mounting shell 13 for mounting the fixing rods 14. The fixing rods 14 are slidably connected inside the through holes, causing the mounting frame 16 to move. One end of the multiple fixing rods 14 is fixedly connected to a connecting frame 15. The lower surface of the connecting frame 15 is fixedly connected to the mounting frame 16. The lower surface of the mounting frame 16 is fixedly connected to an arc plate 17. Two positioning blocks 18 are fixedly connected to the lower surface of the arc plate 17 and engage with the positioning groove 20. Multiple second springs 19 are fixedly connected to the upper surface of the mounting frame 16. The multiple second springs 19 are fixedly connected to the inner wall of the mounting shell 13. The connection between the mounting frame 16 and the arc plate 17 facilitates the pushing action of the positioning blocks 18.
[0038] As attached Figure 5 As shown, the upper surfaces of the two connecting rods 7 and the connecting block 8 are respectively provided with positioning grooves 20. When the positioning groove 20 on the connecting block 8 is engaged with the positioning block 18, it is convenient to limit the positioning post 9 after it extends out of the fixing shell 6. When the positioning groove 20 on the connecting rod 7 is engaged with the positioning block 18, it is convenient to limit the positioning post 9 after it retracts into the fixing shell 6.
[0039] Working principle: In use, first, the steel pipes on the scaffold are wrapped with the fastener body 1. Then, the connecting block 8 is pulled, so that the limiting post 9 is completely inside the fixed shell 6. The positioning block 18 engages with the positioning grooves 20 on the two connecting rods 7, fixing the position of the connecting rods 7. Then, the outside of the stud 2 is tightened by the nut 3, and the connecting frame 15 is pulled up, so that the connecting frame 15 drives the mounting frame 16 to slide inside the mounting shell 13, compressing the second spring 19. Then, the arc plate 17 and the two positioning blocks 18 are disengaged from the positioning grooves 20 on the two connecting rods 7, thus releasing the connecting rods 7. In addition to the limiting action, when the first spring 12 is compressed and rebounds, it pushes the limiting post 9, causing the connecting rod 7 to slide on one side of the fixed shell 6. This pushes the limiting post 9 out of the fixed shell 6 and squeezes the nut 3. Then, the slot 11 is locked on the outside of the two connecting ears 4, limiting the connecting ears 4. Then, the connecting frame 15 is released, and under the action of multiple second springs 19 pushing the mounting frame 16, it is pushed to the arc plate 17, which drives the two positioning blocks 18 to be locked into the positioning groove 20 in the connecting block 8, fixing the position of the limiting post 9. This further fixes the nut 3 and reduces the possibility of loosening.
[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
