Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-3The utility model provides a technical solution: a fast-assembly disc-type scaffolding, including a disc 1, a vertical pole 2, a horizontal pole 3 and an adjustable wedge-shaped pin. A pipe mouth 4 is opened in the middle of the disc 1 and a plurality of groups of docking ports 5 are evenly opened on the periphery. The vertical pole 2 is longitudinally inserted into the pipe mouth 4. The horizontal pole 3 is divided into a plurality of groups and a docking block 6 is fixed at the end. The docking block 6 is transversely opened with a bayonet 7 and longitudinally opened with a socket 8. The edge of the disc 1 is located in the bayonet 7. The adjustable wedge-shaped pin longitudinally passes through the socket 8 and the lower end is inserted into the docking port 5. The adjustable wedge-shaped pin includes a latch 9, a movable plate 10, a pull rod 11, a reset spring 12 and a press-type locker 13. Two groups of movable grooves 14 are symmetrically opened on both sides of the latch 9 and a slide groove 15 is opened on the top. The movable plate 10 There are two groups of pull rods 11, which are respectively located in two groups of movable grooves 14. The pull rod 11 is slidably set in the slide groove 15. The two groups of pull rods 11 are connected by a reset spring 12. The reset spring 12 is located in the middle of the slide groove 15. The push-type locker 13 is installed on the side of the pin 9 and includes a floating pad 16, a pressure plate 17, a clamping rod 18 and a convex ball 19. The floating pad 16 is fixed on the pin 9. The pressure plate 17 is divided into two groups and is symmetrically installed on both sides of the floating pad 16. The clamping rod 18 is divided into two groups and is respectively fixed to the ends of the pressure plate 17. The convex ball 19 is located on the inner side of the pressure rod and fixed on the pin 9. The outer side of the convex ball 19 contacts the pressure plate 17. Two groups of positioning holes 20 are symmetrically opened on the pin 9 and the movable plate 10, and the clamping rod 18 is inserted into the positioning hole 20.

[0019] Further improvement, such as Figure 2 As shown: the latch 9 is wedge-shaped and the upper end is larger than the lower end. The lower end width of the latch 9 is smaller than the width of the docking port 5 and the upper end width is larger than the width of the docking port 5, which facilitates the latch 9 to be inserted into the docking port 5.

[0020] Further improvement, such as Figure 2 As shown: the movable plate 10 is in an arc-shaped structure and has the same arc as the latch pin 9.

[0021] Further improvement, such as Figure 2 As shown, the reset spring 12 is made of elastic metal material and has a plurality of groups of extrusion grooves 21 formed on the surface. The plurality of groups of extrusion grooves 21 are distributed in a stacked manner and can be used for resetting and adjusting the pull rod 11 and the movable plate 10 .

[0022] Specifically, the floating pad 16 includes an outer plate 22 and a floating plate 23 fixed to the inner side of the outer plate 22 . The floating plate 23 is in a stacked structure. Such a design is convenient for pressing and adjusting.

[0023] When in use: the utility model passes the vertical pole 2 through the disc 1 according to the conventional disc-type scaffolding installation method, and snaps the cross bar 3 to be connected into the disc 1, so that the docking port 5 and the socket 8 are located on the same vertical plane. After installation, the staff inserts the adjustable wedge pin longitudinally into the socket 8 and the docking port 5, and makes the movable plate 10 contact with the docking port 5 and the socket 8 to achieve the purpose of limiting. When the scaffolding needs to be disassembled, if the latch 9 is too tight or rusted, the staff first presses the floating pad 16, and the floating pad 16 drives the pressure plate 17 to move toward the outer wall of the latch 9. Restricted by the convex ball 19, the clamping rod 18 rises and moves out of the movable plate 10 and the positioning hole 20 of the latch 9. At this time, the staff moves the two sets of pull rods 11 inward, and drives the movable plate 10 inward during the inward movement, thereby reducing the width of the latch 9, and the latch 9 can be quickly pulled out.
