[0042] Furthermore, in the description of the present invention, “plurality” means two or more than two, unless otherwise clearly and specifically defined.

[0043] See also Figure 1 , Figure 2 and Figure 4 As shown, a disc-type scaffold that can be quickly inserted and fixed is provided, including a connecting mechanism 300 connecting the vertical pole 100 and the horizontal pole 200, the connecting mechanism 300 includes a bearing portion 310, an inserting portion 320 and a limiting portion 330, the bearing portion 310 is arranged on the outer wall of the vertical pole 100, the inserting portion 320 is fixed to the end of the horizontal pole 200, and an active cavity 322 is arranged in the inserting portion 320. When installed, the bearing portion 310 is located in the active cavity 322, and the position of the bearing portion 310 in the active cavity 322 is changed by pressing the horizontal pole 200, and the limiting portion 330 is located in the active cavity 322. When the position of the bearing portion 310 in the active cavity 322 is changed, the limiting portion 330 pops out to fill the active cavity 322, so that the bearing portion 310 is fixed in the active cavity 322.

[0044] Next, through Figure 1-Figure 6 A first embodiment of the present invention is shown:

[0045] exist Figure 2 and Figure 3 In the figure, the bearing part 310 includes a disk 311, which is fixedly sleeved on the outer wall of the vertical pole 100, and a plurality of holes 312 are penetrated through the top of the disk 311. The plurality of holes 312 are arranged in an array with the middle of the disk 311 as the axis, and a groove 313 is opened on the outer ring of the disk 311.

[0046] exist Figure 4In the figure, the plug-in portion 320 includes a connector 321, which is fixedly arranged at both ends of the cross bar 200. An active cavity 322 is provided at the end of the connector 321 close to the disk 311. The height of the active cavity 322 is greater than the thickness of the disk 311. Two through holes 323 communicating with the active cavity 322 are provided on the top of the connector 321. A cylinder 324 and a latch 325 are respectively slidably arranged in the two through holes 323. A connector 326 is arranged between the cylinder 324 and the latch 325. The connector 326 is used to reverse the moving direction of the cylinder 324 on the latch 325, wherein the through hole 323 located at the latch 325 passes through the bottom end of the connector 321.

[0047] The connecting member 326 includes a telescopic rod 340 and a support shaft 341. The telescopic rod 340 is composed of a plurality of sliding connecting rod bodies. One end of the telescopic rod 340 is rotatably connected to the top of the cylinder 324, and the other end is rotatably connected to the top of the pin 325. The support shaft 341 is fixedly set on the top of the connecting head 321, and the support shaft 341 is rotatably connected to the side wall in the middle position of the telescopic rod 340.

[0048] exist Figure 5 In the figure, the limiting part 330 includes a sliding cavity 331, which is located in the connecting head 321 and connected to the active cavity 322. The bottom of the sliding cavity 331 is flush with the bottom of the active cavity 322. A slider 332 is slidably arranged in the sliding cavity 331. A return spring 333 is arranged between the slider 332 and the inner end of the sliding cavity 331. A slot 334 is opened at one end of the slider 332 close to the active cavity 322 so that the top part of the slot 334 can be inserted into the groove 313.

[0049] When in use, the end of the cross bar 200 is brought close to the disk 311, and then the movable cavity 322 is kept horizontal with the disk 311, and then the cross bar 200 is pushed to make the disk 311 located in the movable cavity 322. At this time, the bottom end of the cylinder 324 contacts the top of the disk 311, and the latch 325 is located just above the insertion hole 312, and the limit portion 330 is also blocked by the outer ring of the disk 311 and cannot pop out; then the cross bar 200 is hit, and since there is a distance between the movable cavity 322 and the top of the disk 311, the cross bar 200 will move downward when it is hit, and during the downward movement, the cylinder 324 will be pushed, so that the cylinder 324 moves upward to push one end of the telescopic rod 340 The other end of the telescopic rod 340 applies downward pressure to the latch 325 under the action of the support shaft 341, so that the telescopic rod 340 drives the latch 325 to move downward, and the latch 325 moves downward and is inserted into the socket 312; at the same time, after the cylinder 324 moves upward, the top of the disk 311 fits with the top of the active cavity 322, and a gap is generated between the disk 311 and the bottom of the active cavity 322. The return spring 333 rebounds and pushes the slider 332, so that the slider 332 enters the active cavity 322, and the upper part of the slider 332 located at the slot 334 is inserted into the groove 313, completing the squeezing of the disk 311, so that the disk 311 is fixed in the active cavity 322.

[0050] In summary, by hammering the cross bar 200, the cylinders 324 at both ends of the cross bar 200 drive the pins 325 to move synchronously downward into the movable cavity 322 to fix the vertical pole 100 and the cross bar 200, thereby reducing the number of times the staff knocks on the pins 325 on a cross bar 200 and the number of steps to move, thereby improving the efficiency of installation.

[0051] In addition, in order to improve the efficiency of disassembly, a pull rod 335 is fixedly provided on one side of the slider 332, and one end of the pull rod 335 passes through the side wall of the connecting head 321 and is horizontally slidably connected to the side wall of the connecting head 321. When disassembling, the slider 332 is pushed by the pull rod 335, and the slider 332 moves into the sliding cavity 331. At this time, the slider 332 is disengaged from the groove 313, and then the cylinder 324 is smashed downward to move the pin 325 up and disengage from the socket 312, and then the disassembly is completed.

[0052] Furthermore, in order to achieve installation in a higher environment, the bottom of the connector 321 is slidably connected with a plug post 370, the top of the plug post 370 is inserted into the movable cavity 322, the plug post 370 longitudinally passes through the disc 311 and is slidably connected to the disc 311, and the plug post 370 is located at the bottom of the cylinder 324. When the cross bar 200 is high and difficult to move, the plug post 370 can be knocked upward, and the upward movement of the plug post 370 drives the cylinder 324 upward, and then the pin 325 can be moved downward, and finally the plug post 370 can be taken out.

[0053] In the second embodiment, considering that the distance cannot be easily controlled during the pushing process of the crossbar 200, resulting in the phenomenon that the moving distance is too large or too small, for this purpose, please refer to Figure 3 As shown, the scaffolding also includes a positioning portion, which includes a plurality of limit grooves 314. The limit grooves 314 are arranged on the top of the disk 311, and one end of the limit grooves 314 passes through the outer wall of the disk 311. When in use, the bottom end of the cylinder 324 is located in the limit groove 314, and then the cross bar 200 is pushed to make the cylinder 324 slide to one end of the limit groove 314, and then the cylinder 324 cannot continue to move, and the cross bar 200 cannot be pushed, thereby completing the limit of the push of the cross bar 200.

[0054] The third embodiment, the second embodiment described above can only enter the limiting groove 314 from one end, therefore, the difference between this embodiment and the second embodiment is that, please refer to Figure 5-Figure 9 As shown, the scaffolding also includes a positioning portion, which includes a protrusion 336 and a receiving groove 360. The protrusion 336 is fixedly arranged at one end of the movable cavity 322 close to the disk 311, and the receiving groove 360 ​​is opened on the outer ring of the disk 311. A plurality of receiving grooves 360 are provided, and the receiving groove 360 ​​is plugged into and matched with the protrusion 336. When in use, the protrusion 336 contacts the outer ring of the disk 311 during the pushing process of the cross bar 200. Under the action of the arc surface of the outer wall of the disk 311, the protrusion 336 drives the slider 332 to slide into the sliding cavity 331. When the slider 332 moves to the front of the receiving groove 360, the return spring 333 rebounds and drives the protrusion 336 to be inserted into the receiving groove 360 ​​through the slider 332. At this time, the slider 332 is restricted, and the cross bar 200 cannot be pushed.

[0055] Furthermore, a recessed groove 350 is formed at one end of the latch 325 close to the slider 332 . When the return spring 333 ejects the slider 332 , the protrusion 336 engages with the recessed groove 350 to prevent the latch 325 from moving upward and disengaging from the insertion hole 312 .
