[0025] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a disc-lock scaffold, including a scaffold body 100, the scaffold body 100 including uprights 110 and horizontal bars 120, the horizontal bars 120 further including discs 111 and pins 112, and also including...
[0026] The auxiliary limiting mechanism 200 includes a connecting component 210 and a limiting component 220. The connecting component 210 is slidably sleeved on the crossbar 120. The connecting component 210 also includes a pressing plate 214. The limiting component 220 is limited and installed on one side of the pressing plate 214. The limiting component 220 includes a pin cover plate 224. The pin cover plate 224 is limited and snapped onto the top of the pin 112. The pin cover plate 224 is used to press the pin 112 downward to prevent the pin 112 from falling off during vibration.
[0027] Please see Figure 2 and Figure 3 The end of the crossbar 120 is fixedly connected to a U-shaped slot. The upper and lower sides of the U-shaped slot are respectively provided with through holes. The pin 112 and the disc 111 are used to engage the crossbar 120.
[0028] Please see Figure 4 and Figure 5The connecting assembly 210 also includes a limiting slip ring 211, which is slidably sleeved onto the crossbar 120. A limiting connecting shell 212 is fixedly connected to the top of the limiting slip ring 211. A pressing plate 214 is slidably installed inside the limiting connecting shell 212, and a first spring 215 is fixedly connected to the top of the pressing plate 214. The top of the first spring 215 abuts against the inner top of the limiting connecting shell 212. Through holes are provided on both sides of the limiting connecting shell 212. A limiting plate 216 is fixedly connected to one side of the pressing plate 214, located outside the limiting connecting shell 212. A limiting connecting plate 217 is fixedly connected to the other side of the pressing plate 214, also located outside the limiting connecting shell 212. Multiple sets of first springs 215 are installed evenly inside the limiting connecting shell 212 and fixedly connected to the top of the extrusion plate 214. The first springs 215 are used to extrude the extrusion plate 214, giving the extrusion plate 214 a downward force. A locking bolt 213 is threaded through the bottom of the limiting slip ring 211. The locking bolt 213 abuts against the crossbar 120. If one end of the crossbar 120 does not have a U-shaped groove, the limiting slip ring 211 can be fitted onto the crossbar 120 and slide. The limiting slip ring 211 is fixed by the locking bolt 213.
[0029] The connecting assembly 210 also includes an upper clamping fastener 218 and a lower clamping fastener 219. The upper clamping fastener 218 is fixedly installed at the bottom of the limiting connecting shell 212, and the lower clamping fastener 219 is located directly below the upper clamping fastener 218. Extension plates are provided on both sides of the upper clamping fastener 218 and the lower clamping fastener 219, and through holes are opened at both ends of the extension plates. Both the upper clamping fastener 218 and the lower clamping fastener 219 are arc-shaped. The two sides of the upper clamping fastener 218 and the lower clamping fastener 219 are connected by screws. The upper clamping fastener 218 and the lower clamping fastener 219 are wrapped around both sides of the crossbar 120 and locked by screws, which facilitates installation on the crossbar 120, which has slots at both ends.
[0030] Please see Figure 4 and Figure 5The limiting assembly 220 also includes a limiting rod 221, which is fixedly installed on one side of the limiting connecting plate 217. One end of the pin cover plate 224 is slidably sleeved on the limiting rod 221. The bottom of the pin cover plate 224 has a groove that cooperates with the pin 112. The limiting connecting plate 217 is driven by the first spring 215 and the pressing plate 214 to make the pin cover plate 224 always have a downward force to press the pin 112. The top of the limiting rod 221 is fixedly connected to the limiting block 223. The end of the pin cover plate 224 is located directly below the limiting block 223 and has a groove that cooperates with the limiting block 223. The limiting rod 221 is sleeved with a second spring 222. The second spring 222 is located between the groove of the pin cover plate 224 and the limiting block 223. The second spring 222 is used to move the groove of the pin cover plate 224 away from the limiting block 223, so as to facilitate the rotation of the pin cover plate 224. If the pressing plate 214 has no upward thrust, the first spring 215 will drive the pressing plate 214 to continue to drive the pin cover plate 224 to press down so that the pin cover plate 224 is engaged with the limiting block 223.
[0031] Working principle: After the crossbar 120 and the upright 110 are spliced, the limiting slip ring 211 is sleeved on the crossbar 120. Pulling the limiting slip ring 211 makes the pin cover plate 224 directly above the pin 112. Tightening the locking bolt 213 fixes the position of the limiting slip ring 211. At this time, the first spring 215 presses the pressing plate 214, and the pressing plate 214 drives the pin cover plate 224 to press down. At this time, the pin cover plate 224 engages with the pin 112. While engaging, the pin cover plate 224 will rise slightly. The second spring 222 is squeezed by the slot at the end of the pin cover plate 224 and engaged with the limit block 223 to prevent the pin cover plate 224 from rotating during vibration. If there are joints at both ends of the crossbar 120, the upper clamp fastener 218 and the lower clamp fastener 219 are used for engagement and fixed with screws. When disassembling, the pressing plate 214 is bent upward to release the pin cover plate 224 from the engagement with the pin 112 and the pin cover plate 224 is rotated 90 degrees. Then the pin 112 can be removed.
[0032] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
