Technical Field

[0001] The utility model relates to the technical field of scaffolding, in particular to a double-disc socket and spigot type disc and socket scaffolding. Background Technique

[0002] The double-disc socket and spigot type disc and socket scaffolding is a new type of scaffolding derived from the disc type scaffolding, mainly used for the lighting racks and background racks of large-scale concerts. It is an upgraded product after the bowl and socket type scaffolding, with the characteristics of fewer structures, convenient erection and disassembly. Using the disc type scaffolding can reduce labor time and labor remuneration, ensure work, and reduce the number of components.

[0003] For the existing scaffolding, for the upright columns in contact with the ground, leveling blocks need to be additionally added below them to horizontally adjust the whole scaffolding, which is inconvenient to use. Secondly, the connection between the upright columns is of the plug-in type, but a pin rod is needed to fix the two. During use, the pin rod is easy to lose and inconvenient to use. Finally, the cross bar and the upright column are connected through a disc and a connecting block, and a wedge needs to be inserted into the fixing hole of the disc. After using for a period of time, the wedge becomes loose and is easy to fall off and cause danger. Therefore, a double-disc socket and spigot type disc and socket scaffolding is proposed for the above problems. Content of the Utility Model

[0027] Please refer to Figures 1-8 , the present utility model provides a technical solution:

[0028] A double-disc socket-type disk button scaffold, comprising a support rod 1, a disk 5, a sleeve 6, a connecting rod 8, a cross bar 20, a connecting block 21 and a wedge 23. The inner bottom end of the support rod 1 is threadedly connected with a screw rod 2. The bottom end of the screw rod 2 is fixedly connected with a chassis 3. The bottom end of the chassis 3 is fixedly connected with spike teeth 4. Two disks 5 in a group are fixedly connected to the middle position of the support rod 1. The top end of the support rod 1 is fixedly connected with a sleeve 6. Two symmetrically arranged fixing holes 7 are provided on the outer side of the sleeve 6. The bottom end of the connecting rod 8 is fixedly connected with a fixing rod 9. A fixing block 10 is fixedly connected to the inner bottom end of the fixing rod 9. A fixed shaft 11 is fixedly connected to the outer side of the fixing block 10. A fixing pin 12 is rotatably connected to the outer side of the fixed shaft 11. A positioning shaft 13 is fixedly connected to the outer side of the fixing pin 12. A slider 14 is slidably connected to the outer side of the positioning shaft 13. A vertical rod 15 is fixedly connected to the bottom end of the slider 14. A spring 16 is provided on the outer side of the vertical rod 15. A baffle 17 is provided at the bottom end of the spring 16. A circular hole 18 is provided at the bottom end of the fixing rod 9. Two symmetrically arranged through holes 19 are provided on the outer side of the fixing rod 9. Connecting blocks 21 are fixedly connected to both ends of the cross bar 20. A positioning hole 22 penetrating through the connecting block 21 is provided at one end of the connecting block 21.

[0029] A cross shaft 24 is fixedly connected inside the wedge 23. A moving plate 25 is slidably connected to the outer side of the cross shaft 24 through a guiding groove 26; the top end of the connecting rod 8 is fixedly connected with a sleeve 6. Two symmetrically arranged fixing holes 7 are provided on the outer side of the sleeve 6; the diameter of the fixing rod 9 is slightly smaller than the diameter of the sleeve 6, and the length of the fixing rod 9 is equal to the length of the sleeve 6; the baffle 17 and the vertical rod 15 are slidably connected, and the diameter of the baffle 17 is larger than the diameter of the circular hole 18.

[0030] Working process: When using the device, first stand the support rod 1 on the ground, the chassis 3 is in contact with the ground, and the spike teeth 4 are inserted into the soil. The screw rod 2 provided with the support rod 1 is adjusted to make the disc 5 on the support rod 1 reach the specified height. After the support rod 1 is installed, the cross bar 20 is installed between the two support rods 1, and the connecting blocks 21 at both ends of the cross bar 20 are placed between the two discs 5. The positioning holes 22 are aligned with the mounting holes on the disc 5, and then the moving plate 25 on the wedge 23 is adjusted to be in a straight line with the wedge 23 through the guide groove 26. Then, the wedge 23 is passed through the positioning hole 22, and the worker uses a hammer to hit the top of the wedge 23, so that the wedge-shaped wedge 23 is firmly stuck in the positioning hole 22, and then the movable plate 25 is rotated 90 degrees through the horizontal axis 24, so that the movable plate 25 and the wedge 23 form a vertical state. Since the guide groove 26 is L-shaped, the horizontal axis 24 is kept in the top protruding part of the guide groove 26 when the movable plate 25 is in the horizontal state to prevent the movable plate 25 from rotating under the action of external force. At this time, the connection between the cross bar 20 and the support rod 1 is completed, and then the fixed The through hole 19 on the fixed rod 9 and the fixed hole 7 on the sleeve 6 are on a vertical line. The fixed rod 9 at the bottom of the connecting rod 8 is inserted into the sleeve 6. When the fixed rod 9 has not reached the bottom of the sleeve 6, the vertical rod 15 will first press against the bottom of the sleeve 6. Since the fixed rod 9 will continue to move toward the bottom end of the sleeve 6, the vertical rod 15 will move upward against the slider 14. The fixed pin 12 will rotate outward around the fixed axis 11 under the upward movement of the slider 14, and the positioning axis 13 on the fixed pin 12 will slide left and right in the movable hole inside the slider 14. The fixing block 10 fixes the fixing pin 12. When the slider 14 moves upward, the spring 16 will be stretched. The baffle 17 is blocked between the spring 16 and the round hole 18. After the fixing rod 9 completely enters the interior of the sleeve 6, the fixing pin 12 will pass through the fixing hole 7 to fix the upper and lower rods. Compared with the previous scaffolding, workers do not need to use connecting parts to fix the upper and lower rods, which reduces the difficulty of installation. When disassembling, only the fixing rod 9 needs to be lifted upward. Under the elastic force of the spring 16, the slider 14 will move to the bottom of the fixing rod 9, so that the fixing pin 12 rotates around the fixed axis 11 toward the inside of the fixing rod 9 and returns to the inside of the fixing rod 9 through the through hole 19.
