Abstract
Description
Technical Field
[0001] This utility model belongs to the field of scaffolding technology, and more specifically, relates to a disc-lock scaffolding structure. Background Technology
[0002] Disc-lock scaffolding is a new type of scaffolding, mainly constructed of aluminum alloy structural steel. Its strength is approximately twice that of ordinary carbon steel scaffolding, making it sturdy, high-strength, and with a more stable and safer overall structure. This scaffolding consists of uprights, horizontal bars, turnbuckles, and pins, allowing for rapid assembly and disassembly. It is structurally stable and reliable, highly versatile, and has a large load-bearing capacity, making it widely used in the construction of houses, bridges, tunnels, chimneys, water towers, and other buildings.
[0003] In existing technologies, horizontal bars are typically secured to basket trays using pins during scaffolding erection. However, improper installation can lead to the pins coming loose, especially under conditions of significant external environmental changes. This increases safety hazards during scaffolding use and negatively impacts construction safety. Utility Model Content
[0004] This utility model provides a disc-lock scaffolding structure that can be limited by a limiting member in the second through hole to prevent the pin from loosening or falling off, thus eliminating safety hazards.
[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A disc-lock scaffolding structure is provided, including an upright, a U-shaped clip, a horizontal bar, a pin, and a limiting member. The upright is arranged vertically and a basket tray is fixedly fitted around its outer periphery, with a first locking hole penetrating through the basket tray. The U-shaped clip is secured to the outer edge of the basket tray, and a second locking hole, opposite to the first locking hole, is penetrating through the U-shaped clip vertically. The horizontal bar is connected to the outside of the U-shaped clip and extends horizontally. The pin is inserted into the first and second locking holes, and a first through hole extending downwards to the lower end of the pin and located below the U-shaped clip is horizontally penetrating through the pin. A second through hole communicating with the upper end of the first through hole is also horizontally penetrating through the pin. The limiting member is inserted into the second through hole, and the limiting member can enter the first and second through holes sequentially from the lower end of the pin.
[0006] In one possible implementation, the pin has a horizontally penetrating third through hole that communicates with the end of the second through hole away from the first through hole, the third through hole extending downward and capable of accommodating the limiting member.
[0007] In some embodiments, the pin has a fourth through hole that is horizontally connected to the lower end of the third through hole, and the fourth through hole extends obliquely downward.
[0008] In some embodiments, the fourth through hole extends toward the direction of the first through hole.
[0009] In some embodiments, the lower end of the fourth through hole has a large hole end with an inner diameter much larger than the outer diameter of the limiting member, for accommodating the limiting member.
[0010] In one possible implementation, the limiting element is a U-bolt with two extension arms located on either side of the pin, the extension arms being used to limit the U-bolt from lateral disengagement from the pin.
[0011] In one possible implementation, the end face of the basket tray is provided with an axially extending positioning plate, and the U-shaped card is provided with a positioning slot through the vertical direction for interlocking with the positioning plate, the positioning slot extending to the end of the U-shaped card away from the crossbar.
[0012] In some embodiments, the positioning plate is connected to the outer peripheral wall of the upright.
[0013] In one possible implementation, the U-shaped clip is threadedly connected to the crossbar via a screw.
[0014] In one possible implementation, the upper end of the pin has a limiting platform that protrudes outward and is used to abut against the top surface of the U-shaped card.
[0015] The disc-lock scaffolding structure provided in this embodiment, compared with the prior art, inserts the pin into the first locking hole and the second locking hole until the lower end of the pin protrudes below the U-shaped clip. At this time, the limiting member is inserted from the lower end of the pin, first entering the first through hole, and then pushing upward into the second through hole. The limiting member is retained and limited in the second through hole to prevent the pin from loosening or falling off, thus eliminating safety hazards. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a number" means two or more, unless otherwise explicitly specified.
[0021] The vertical direction mentioned throughout the text is Figure 1 The direction indicated by the middle arrow.
[0022] Please see Figures 1 to 8 The disc-lock scaffolding structure provided by this utility model will now be described. The disc-lock scaffolding structure includes an upright 10, a U-shaped clip 20, a horizontal bar 30, a pin 40, and a limiting member 50. The upright 10 is arranged vertically and a basket tray 11 is fixedly fitted around its outer periphery. A first locking hole 12 is provided through the basket tray 11. The U-shaped clip 20 is clipped onto the outer edge of the basket tray 11, and a second locking hole 21 is provided through the U-shaped clip 20 along its vertical direction, opposite to the first locking hole 12. The horizontal bar 30 is connected to the outside of the U-shaped clip 20 and... The pin 40 is inserted into the first locking hole 12 and the second locking hole 21. The pin 40 has a first through hole 41 that extends downward to the lower end of the pin 40 and is located below the U-shaped card 20. The pin 40 also has a second through hole 42 that communicates with the upper end of the first through hole 41. The limiting member 50 is inserted into the second through hole 42. The limiting member 50 can enter the first through hole 41 and the second through hole 42 from the lower end of the pin 40.
[0023] This application provides a disc-lock scaffolding structure. In practical use, the dual locking mechanism of the pin 40 and the limiting member 50 significantly improves the reliability and safety of the connection. Specifically, the basket tray 11 on the upright 10 is connected to the U-shaped clip 20 via the pin 40. The first through hole 41 and the second through hole 42 on the pin 40 allow the limiting member 50 to be inserted and fixed from the bottom. This design prevents the pin 40 from accidentally coming loose under vibration or load, reducing the risk of scaffolding collapse. Simultaneously, the horizontal bar 30 is horizontally connected to the outside of the U-shaped clip 20, ensuring the stability of the overall structure and making it suitable for high-altitude operations. The design of the first through hole 41 and the second through hole 42 of the pin 40 allows the limiting member 50 to pass through sequentially from bottom to top, making the installation process intuitive and simple, reducing the difficulty of worker operation, and improving assembly efficiency. Furthermore, this structure reduces metal fatigue points, extends the service life of the scaffolding, and meets the safety standards of the construction industry.
[0024] In use, first place the upright post 10 vertically on the ground or foundation, ensuring its vertical stability. Then, attach the U-shaped clip 20 to the outer edge of the basket tray 11, aligning the second locking hole 21 on the U-shaped clip 20 with the first locking hole 12 on the basket tray 11. Next, insert the pin 40 into the first locking hole 12 and the second locking hole 21 until the lower end of the pin 40 protrudes below the U-shaped clip 20. At this point, the limiting member 50 is inserted from the lower end of the pin 40, first entering the first through hole 41, and then pushing upward into the second through hole 42. The limiting member 50 remains in the second through hole 42, preventing the pin 40 from loosening or falling off, thus eliminating safety hazards. The entire process requires no special tools and can be completed quickly by workers; disassembly is performed by reversing the operation.
[0025] The disc-lock scaffolding structure provided in this embodiment, compared with the prior art, involves inserting the pin 40 into the first locking hole 12 and the second locking hole 21 until the lower end of the pin 40 protrudes below the U-shaped clip 20. At this time, the limiting member 50 is inserted from the lower end of the pin 40, first entering the first through hole 41, and then pushing upward into the second through hole 42. The limiting member 50 remains in the second through hole 42 to limit and prevent the pin 40 from loosening or falling off, thus eliminating safety hazards.
[0026] In one possible implementation, the aforementioned pin 40 adopts as follows: Figures 3 to 7 The structure shown is described in the following document. Figures 3 to 7 The pin 40 has a horizontally penetrating third through hole 43 that communicates with the end of the second through hole 42 that is away from the first through hole 41. The third through hole 43 extends downward and can accommodate the limiting member 50.
[0027] Specifically, the third through hole 43 is connected to the second through hole 42, allowing the limiting member 50 to move further into the third through hole 43 after insertion. The downward extension of the third through hole 43 allows the limiting member 50 to fall naturally into the hole under the action of gravity, reducing the need for manual adjustment, making installation more convenient, and also ensuring that the limiting member 50 is stably in the third through hole 43.
[0028] Once the limiting member 50 has entered the first through hole 41 and the second through hole 42 from the lower end of the pin 40, the worker can continue to push the limiting member 50, moving it from one end of the second through hole 42 into the third through hole 43. During installation, the worker only needs to confirm that the limiting member 50 is fully inserted into the third through hole 43. During disassembly, the worker must first pull the limiting member 50 back into the second through hole 42 and then remove it downwards. The entire process is smooth and requires no forceful operation, making it suitable for construction site environments with frequent assembly and disassembly.
[0029] In some embodiments, see Figures 3 to 7 The pin 40 is horizontally provided with a fourth through hole 44 that communicates with the lower end of the third through hole 43, and the fourth through hole 44 extends obliquely downward.
[0030] Specifically, the fourth through hole 44, extending obliquely downwards, utilizes the principle of gravity self-locking to make it easier for the limiting member 50 to enter and lock in the ideal position. The fourth through hole 44 is connected to the lower end of the third through hole 43. The oblique channel enhances the vibration resistance of the limiting member 50. When the scaffolding is subjected to dynamic loads, the limiting member 50 is less likely to loosen and detach from the fourth through hole 44, thus improving overall safety.
[0031] In use, the limiting member 50 enters the fourth through hole 44 from the lower end of the third through hole 43. Because the fourth through hole 44 is inclined downwards, the worker only needs to gently push the limiting member 50, and it will slide smoothly into the bottom of the hole. After installation, the limiting member 50 is in an inclined state within the fourth through hole 44, forming a surface contact with the wall of the pin 40 hole, making it more impact-resistant and preventing it from falling off than a vertical channel. For disassembly, the worker simply pulls the limiting member 50 out in the opposite direction of the incline; the operation is simple.
[0032] In some embodiments, see Figures 3 to 7 The fourth through hole 44 extends toward the direction close to the first through hole 41.
[0033] Specifically, during installation, when the limiting member 50 enters the fourth through hole 44 from the third through hole 43, the limiting member 50 will naturally move towards the first through hole 41 because the fourth through hole 44 extends towards the first through hole 41. The worker can observe the direction of movement of the limiting member 50 to ensure that it is fully inserted into the end of the fourth through hole 44.
[0034] The first through hole 41, the second through hole 42, the third through hole 43 and the fourth through hole 44 can form a tortuous path to prevent the limiting member 50 from returning from the fourth through hole 44 to the first through hole 41 and disengaging from the pin 40 due to vibration.
[0035] In some embodiments, see Figure 7 The lower end of the fourth through hole 44 has a large hole end 45 with an inner diameter much larger than the outer diameter of the limiting member 50, which is used to accommodate the limiting member 50.
[0036] Specifically, the large hole end 45 can provide freedom of movement for the limiting member 50. The large hole end 45 also reduces edge stress, prevents wear of the limiting member 50, and helps to prevent the limiting member 50 from disengaging from the fourth through hole 44 in a vibration environment.
[0037] In one possible implementation, the aforementioned limiting member 50 adopts, as shown in... Figure 4 and Figure 6 The structure shown is described in the following document. Figure 4 and Figure 6 The limiting member 50 is a U-bolt, which has two extension arms 51 located on both sides of the pin 40. The extension arms 51 are used to limit the U-bolt from disengaging laterally from the pin 40.
[0038] Specifically, the two extension arms 51 of the U-bolt limit the pin 40 on both sides to prevent lateral disengagement. This ensures that the U-bolt can only enter the fourth through hole 44 through the path formed by the first through hole 41, the second through hole 42, the third through hole 43, and the fourth through hole 44, or disengage from the pin 40. This limits the upward movement of the pin 40 and prevents it from coming out of the first locking hole 12 and the second locking hole 21.
[0039] In one possible implementation, the aforementioned flower basket tray 11 adopts the following... Figures 1 to 6 The structure shown is described in the following document. Figures 1 to 6 The end face of the flower basket tray 11 is provided with an axially extending positioning plate 13. The U-shaped card 20 is provided with a positioning slot 22 through the vertical direction for interlocking with the positioning plate 13. The positioning slot 22 extends to the end of the U-shaped card 20 away from the crossbar 30.
[0040] Specifically, the positioning plate 13 extends axially to the end face of the basket tray 11 and engages with the positioning slot 22 on the U-shaped clip 20. This eliminates the possibility of the U-shaped clip 20 rotating or shifting, allowing the first locking hole 12 and the second locking hole 21 to automatically align, improving installation accuracy and speed. This design also reduces wear on the pin 40, as the pin 40 inserts smoothly after alignment without the need for forced correction.
[0041] Furthermore, two positioning plates 13 are symmetrically provided on both sides of the first locking hole 12.
[0042] Specifically, a balanced positioning force is provided to prevent the U-shaped clip 20 from tilting or wobbling. The symmetrical design ensures that the U-shaped clip 20 is subjected to uniform force, reducing localized stress and improving connection stability. The two positioning plates 13 guide the U-shaped clip 20 like guide rails, ensuring that it remains level during installation, making it suitable for heavy-duty applications.
[0043] Furthermore, the positioning plate 13 is provided in two sets, which are located on the upper and lower end faces of the flower basket plate 11 respectively.
[0044] Specifically, the positioning plates 13 are set into two sets, located on the upper and lower ends of the flower basket tray 11 respectively, which further increases the stability after installation.
[0045] In some embodiments, see Figures 1 to 6 The positioning plate 13 is connected to the outer peripheral wall of the upright 10.
[0046] Specifically, by directly connecting the positioning plate 13 to the outer peripheral wall of the upright 10 (usually through welding), it is equivalent to adding a reinforcing rib between the basket tray 11 and the upright 10, thus changing the stress distribution mode of the basket tray 11. When the U-shaped clip 20 is subjected to a load from the crossbar 30, the force can be directly and efficiently transferred to the main structure of the upright 10 through the positioning plate 13, rather than relying solely on the localized area where the basket tray 11 and the upright 10 are joined. This effectively reduces stress concentration at the base of the basket tray 11, preventing deformation or breakage due to long-term heavy loads or impacts.
[0047] In one possible implementation, the aforementioned U-shaped card 20 adopts the following... Figure 8 The structure shown is described in the following document. Figure 8 The U-shaped clip 20 is threadedly connected to the crossbar 30 via the screw 70.
[0048] Specifically, the threaded connection features continuous adjustment. By rotating the screw 70, the tightness between the crossbar 30 and the U-shaped clip 20 can be finely adjusted, eliminating gaps caused by manufacturing tolerances or wear, and achieving a tight connection with "zero wobbling." This preload can significantly improve the rigidity of the joint, reduce micro-deformation of the scaffolding under load, and enhance overall stability.
[0049] Furthermore, both ends of the crossbar 30 are equipped with U-shaped clips 20. When the U-shaped clips 20 at both ends of the crossbar 30 are fixed, rotating the crossbar 30 can make the two U-shaped clips 20 move closer or further apart, thus achieving bidirectional adjustment.
[0050] In one possible implementation, the aforementioned pin 40 adopts as follows: Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The structure shown is described in the following document. Figure 1 , Figure 2 , Figure 5 , Figure 6 and Figure 7 The upper end of the pin 40 is provided with a limiting platform 60 that protrudes outward and is used to abut against the top surface of the U-shaped card 20.
[0051] Specifically, the limiting platform 60 protrudes outwards and abuts against the top surface of the U-shaped clip 20, ensuring that the pin 40 stops in the correct position and avoiding the problem of the lower end of the pin 40 being too long or too short. This improves the consistency of the connection and reduces safety risks. The limiting platform 60 also serves as a visual marker, allowing workers to quickly determine whether the pin 40 is in place.
[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
