Description
Technical Field
[0001] This utility model relates to the field of fastener technology, specifically a fastener for building construction scaffolding. Background Technology
[0002] Fasteners, also known as couplers, connecting fasteners, or tie rods, are an important type of fastener in construction scaffolding. They serve to tightly connect various components of the scaffolding (such as uprights, horizontal bars, and diagonal braces), ensuring the structural stability and safety of the entire scaffolding. They can effectively connect multiple pipes, making the scaffolding structure more robust. They are typically used to connect uprights and horizontal bars, or to connect diagonal braces.
[0003] Existing scaffolding fasteners used outdoors for extended periods are prone to rusting, which can reduce their strength and durability, thereby affecting the overall safety and stability of the scaffolding. Due to the accumulation of rust, the rotation and adjustment of the fasteners may become difficult or even jammed. In some cases, workers may need to exert extra effort to overcome this blockage, leading to fatigue and potential safety hazards.
[0004] Patent document CN212406085U discloses a connector for fixing steel pipe scaffolding, "including a fastener body and a fixing pin. The fastener body includes two vertically placed and welded-fixed left and right U-shaped grooves. Each of the two sides of the left and right U-shaped grooves has a first and a second socket with different opening sizes. The first and second sockets are used to insert the fixing pin to fix the steel pipe. The major axis width of the first socket is greater than that of the second socket, enabling the erection of steel pipe scaffolding with alternating horizontal and vertical steel pipes. The connection is firm, operation is convenient and quick, disassembly is simple, and it is not easily damaged." However, the connector for fixing steel pipe scaffolding in the above-mentioned disclosure mainly considers ease of connection and disassembly, but does not consider the ease of applying lubricating oil to reduce the impact of rust on the rotation of the fastener. Therefore, it is necessary to develop a fixing component for construction scaffolding. Utility Model Content
[0005] The purpose of this utility model is to provide a fastener for building construction scaffolding to solve the technical problem mentioned in the background art of not being able to apply lubricating oil to the rotating parts of the fastener for lubrication.

A connecting shaft is fixedly installed on the first fixing buckle. A cylinder corresponding to the connecting shaft is fixedly installed inside the second fixing buckle, and one end of the connecting shaft extends into an annular groove. An annular groove is provided inside the cylinder. A retaining ring corresponding to the annular groove is installed around the connecting shaft, and the retaining ring engages with the annular groove. An annular flow channel is embedded inside the retaining ring, and holes are arranged in an array on the annular flow channel. A support frame is fixedly installed on the first fixing buckle, and a conveying component for conveying lubricating oil is provided inside the support frame. Both the first and second fixing buckles are provided with fixing components.
[0007] Preferably, the fixing component includes a positioning bolt and a nut, with positioning bolts passing through the interior of both the first fixing buckle and the second fixing buckle, and the nut being threaded onto the positioning bolt.
[0008] Preferably, the conveying assembly includes a liquid storage tank, a conveying pipe, and a pushing assembly. The liquid storage tank is embedded inside the support frame, the conveying pipe is disposed inside the support frame, one end of the conveying pipe is connected to the liquid storage tank, and the other end of the conveying pipe is connected to an annular flow channel. The pushing assembly is disposed inside the liquid storage tank.
[0009] Preferably, the pushing assembly includes a piston block, a threaded cylinder, and a threaded rod. The piston block is disposed inside the liquid storage tank, and the outer wall of the piston block is in contact with the inner wall of the liquid storage tank. The threaded cylinder is embedded inside the piston block, and the threaded rod is threadedly connected inside the threaded cylinder, with one end of the threaded rod rotatably connected to the support frame.
[0010] Preferably, the support frame has a knob on its side, and the center of the knob is fixedly connected to one end of the threaded rod.
[0011] Preferably, the support frame is provided with a filling pipe inside, and the filling pipe is connected to the liquid storage tank. One end of the filling pipe is connected to a sealing cap by a thread.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. This utility model facilitates lubrication by installing an annular flow channel and holes.

[0018] 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.
[0019] Please see Figure 1 , Figure 2 and Figure 3A type of scaffolding fastener for construction includes a first fastener 1 and a second fastener 3. A connecting shaft 2 is fixedly installed on the first fastener 1. A cylinder 6 corresponding to the connecting shaft 2 is fixedly installed inside the second fastener 3, with one end of the connecting shaft 2 extending into an annular groove 7. The cylinder 6 has an annular groove 7 inside. A retaining ring 8 corresponding to the annular groove 7 is mounted around the connecting shaft 2, and the retaining ring 8 engages with the annular groove 7. An annular flow channel 9 is embedded inside the retaining ring 8, and holes 10 are arranged in an array on the annular flow channel 9. A support frame 11 is fixedly installed on the first fastener 1, and a conveying component for conveying lubricating oil is provided inside the support frame 11. Both the first fastener 1 and the second fastener 3 are equipped with fixing components. When using the scaffolding fastener to support and fix the scaffolding connection, after the first fastener 1 is placed on the scaffolding, the fixing components secure the first fastener 1. Fixed buckle 1 is fixed in position, while the second fixed buckle 3 is rotated. Through the cooperation of connecting shaft 2 and cylinder 6, the second fixed buckle 3 can rotate 360 degrees. After adjusting the second fixed buckle 3 to the predetermined angle, through the cooperation of the fixing components, the second fixed buckle 3 is fixedly connected to the scaffold, thereby achieving the purpose of supporting and fixing the connection of the construction scaffold. The annular groove 7 and the retaining ring 8 cooperate to limit the position of cylinder 6 and connecting shaft 2, preventing them from separating. When applying lubricating oil to the inside of connecting shaft 2 and cylinder 6, the lubricating oil is transported into the annular flow channel 9 through the movement of the conveying component. Through the hole 10, the lubricating oil flows between connecting shaft 2 and cylinder 6, thereby facilitating the application of lubricating oil and preventing rusting at the connection due to prolonged exposure, which would affect rotation. The automatic application of lubricating oil improves the practicality of the construction scaffold fixing components.
[0020] Please see Figure 1 and Figure 2 The fixing components include positioning bolts 4 and nuts 5. Positioning bolts 4 are inserted inside both the first fixing buckle 1 and the second fixing buckle 3. Nuts 5 are threaded onto the positioning bolts 4. After the first fixing buckle 1 and the second fixing buckle 3 are fixed on the scaffold, the tightness of the first fixing buckle 1 and the second fixing buckle 3 can be adjusted by connecting the positioning bolts 4 and the nuts 5 and adjusting the position of the nuts 5.
[0021] Please see Figure 3The conveying assembly includes a liquid storage tank 13, a conveying pipe 17, and a pushing assembly. The liquid storage tank 13 is embedded inside the support frame 11. The conveying pipe 17 is located inside the support frame 11, with one end of the conveying pipe 17 connected to the liquid storage tank 13 and the other end connected to the annular flow channel 9. The pushing assembly is located inside the liquid storage tank 13. When applying lubricating oil, the movement of the pushing assembly pushes and squeezes the lubricating oil stored in the liquid storage tank 13, causing the lubricating oil to flow into the conveying pipe 17. The conveying pipe 17 then causes the lubricating oil to flow into the annular flow channel 9, and through the hole 10, the lubricating oil flows to the connecting shaft 2 and the cylinder 6 for lubrication.
[0022] Please see Figure 3 The pushing assembly includes a piston block 14, a threaded cylinder 15, and a threaded rod 16. The piston block 14 is disposed inside the liquid storage tank 13, and the outer wall of the piston block 14 is in contact with the inner wall of the liquid storage tank 13. The threaded cylinder 15 is embedded inside the piston block 14, and the threaded rod 16 is threadedly connected inside the threaded cylinder 15. One end of the threaded rod 16 is rotatably connected to the support frame 11. When the pushing assembly moves, the knob 12 will drive the threaded rod 16 to rotate. The rotation of the threaded rod 16 will cause the piston block 14 to move through the threaded cylinder 15. In turn, the movement of the piston block 14 will squeeze and push the lubricating oil stored inside the liquid storage tank 13.
[0023] Please see Figure 2 and Figure 3 The support frame 11 has a knob 12 on its side, and the center of the knob 12 is fixedly connected to one end of the threaded rod 16. The support frame 11 has a filling tube 18 inside, and the filling tube 18 is connected to the liquid storage tank 13. One end of the filling tube 18 is connected to a sealing cap by a thread, and the filling tube 18 facilitates the addition of lubricating oil into the liquid storage tank 13.
[0024] Working principle: First, when using scaffold fixing components to support and fix the scaffold connections, after setting the first fixing buckle 1 on the scaffold, it is connected to the nut 5 via the positioning bolt 4. Adjusting the position of the nut 5 adjusts the tightness of the first fixing buckle 1 and the second fixing buckle 3. Simultaneously, rotating the second fixing buckle 3 allows it to rotate 360 degrees through the cooperation of the connecting shaft 2 and the cylinder 6. After adjusting the second fixing buckle 3 to the predetermined angle, the fixing components work together to fix the second fixing buckle 3 to the scaffold, thus achieving the purpose of supporting and fixing the scaffold connections. The annular groove 7 and the retaining ring 8 cooperate to secure the cylinder 6. The position of the connecting shaft 2 is limited to prevent separation. When applying lubricating oil to the inside of the connecting shaft 2 and the cylinder 6, the screw rod 16 will rotate through the knob 12. The rotation of the screw rod 16 will cause the piston block 14 to move through the screw cylinder 15. The movement of the piston block 14 will squeeze and push the lubricating oil stored in the liquid storage tank 13. The lubricating oil is delivered into the annular flow channel 9 through the delivery pipe 17. Through the hole 10, the lubricating oil will flow between the connecting shaft 2 and the cylinder 6, which facilitates the application of lubricating oil and avoids rusting at the connection point due to long-term exposure, which would affect rotation. The automatic application of lubricating oil improves the practicality of the scaffolding fixing parts in construction.
