DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 - 3 , in the embodiment of the present utility model, a button - and - socket type scaffolding structure includes a vertical pole 3 and a support platform 2 movably sleeved on the outer peripheral surface of the vertical pole 3. A plurality of cross - bars 1 are inserted and arranged on the annular side wall of the support platform 2. A support mechanism for fixing a plurality of inclined rods 16 is installed on the upper surface of the support platform 2. The support mechanism includes a plurality of fixing components respectively fixing a plurality of inclined rods 16. A control mechanism is installed on the support platform 2 and is configured to inflate the fixing component to lock the inclined rod 16 inside it.

[0022] Specifically, a support platform 2 that can move along the length direction of the vertical pole 3 is sleeved on the outer peripheral surface of the vertical pole 3. A plurality of crossbars 1 are threadedly inserted into the annular side wall of the support platform 2. By rotating the crossbars 1, the crossbars 1 can be fixed on the support platform 2 or removed from the support platform 2. At the same time, the end of the diagonal bar 16 is inserted into the interior of the support mechanism, so that the position of the diagonal bar 16 can be fixed, thereby ensuring the stability of the overall scaffolding. Under the action of the control mechanism, the support mechanism is controlled to fix or release the diagonal bar 16, and then the rapid connection between the crossbar 1, the vertical pole 3 and the diagonal bar 16 is completed, so as to facilitate the operator to assemble or disassemble the scaffolding and improve the overall work efficiency.

[0023] Please refer to Figure 1 , in one embodiment, in this embodiment, preferably, the support mechanism further includes an annular turntable 11 arranged on the support platform 2. A sealed cavity is installed inside the annular turntable 11, and a plurality of fixing components are installed on the upper surface of the annular turntable 11.

[0024] Specifically, with the arrangement of the annular turntable 11, the fixing components can be better fixed on the support platform 2. Secondly, the sealed cavity inside the annular turntable 11 can better establish a sealed air delivery channel between the control mechanism and the fixing components, facilitating the gas in the control mechanism to smoothly enter the interior of the fixing components through the sealed cavity and driving the fixing components to perform the next action.

[0025] Please refer to Figure 1 , in one embodiment, in this embodiment, preferably, the fixing component includes a fixing seat 13 installed on the upper surface of the annular turntable 11 and a connecting seat 14 installed inside the fixing seat 13. An inflatable cavity 15 is formed inside the wall of the connecting seat 14. A plurality of piston tubes 17 communicating with the inflatable cavity 15 are installed on the inner wall of the connecting seat 14. Piston members are slidably arranged in the plurality of piston tubes 17, and the end of the piston member is connected to the clamping plate 18. Further, a spring connected to the inner wall of the inflatable cavity 15 is connected to the end of the piston member. The clamping plate 18 preliminarily limits the diagonal bar 16 under the drive of the spring. As the control mechanism conveys air into the inner side of the inflatable cavity 15, the piston member drives the clamping plate 18 to move, clamping and fixing the diagonal bar 16 located inside the connecting seat 14, ensuring the stability of the diagonal bar 16 after installation.

[0026] Specifically, when the gas enters the inflatable cavity 15, it will squeeze the gas located in the inflatable cavity 15 into the interior of the piston tube 17. At the same time, the piston tube 17 squeezes the piston member to displace, and the piston member drives the clamping plate 18 to contact the outer surface of the diagonal bar 16, thereby fixing the diagonal bar 16 inserted into the connecting seat 14. When the interior of the inflatable cavity 15 deflates, the diagonal bar 16 can be pulled out from the connecting seat 14.

[0027] Please refer to Figures 1 - 2, in one embodiment, preferably, support tubes 21 communicating with the inside of the inflatable cavity 15 are symmetrically arranged on the outer side wall of the connecting seat 14. The ends of the support tubes 21 away from the connecting seat 14 are all connected to the inner wall of the fixed seat 13. A gear is installed on the outer peripheral surface of one of the support tubes 21. A driving member is installed on the fixed seat 13, and a rack 22 driven by the driving member is installed on the driving member. The rack 22 meshes with the gear. Further, the driving member can drive the rack 22 to reciprocate. When the rack 22 reciprocates, it can drive the gear meshing with it to rotate, and the support tube 21 connected to the gear will also rotate synchronously. At this time, the angle of the connecting seat 14 can also be adjusted. When it is necessary to adjust the inclination angle of the connecting seat 14 to fit the inclined rod 16, only need to turn on the driving member to complete the adjustment of the angle of the connecting seat 14.

[0028] Please refer to Figures 1 - 3 , in one embodiment, preferably, a plurality of clamping mechanisms for locking the support platform 2 to the vertical rod 3 are further installed on the support platform 2. The clamping mechanism includes an annular connection box 19 fixedly installed inside the support platform 2. A voltage stabilizing tube communicating with the inside of the control mechanism is fixedly installed on the annular connection box 19. A fixed tube 20 is fixedly installed on the inner wall of the support platform 2. The fixed tube 20 is connected to the annular connection box 19 through an air pipe 23. A locking member for locking the position of the support platform 2 on the vertical rod 3 during inflation is installed inside the fixed tube 20.

[0029] Specifically, the control component can drive the clamping component to keep the support platform 2 and the vertical rod 3 stably connected. Under the action of the clamping mechanism, the support platform 2 can be fixed at any height on the vertical rod 3. Under the action of the voltage stabilizing tube, the inside of the control mechanism is communicated with the inside of the annular connection box 19 to ensure that the gas in the control mechanism can smoothly enter the inside of the annular connection box 19 through the voltage stabilizing tube. Secondly, the gas enters the inside of the fixed tube 20 through the air pipe 23 and squeezes the locking member located inside the fixed tube 20 to contact the surface of the vertical rod 3. When there is gas squeezing the locking member on the side of the fixed tube 20 away from the vertical rod 3, the locking member will lock on the surface of the vertical rod 3 to achieve the locking effect. When there is no gas squeezing the locking member on the side of the fixed tube 20 away from the vertical rod 3, the position of the support platform 2 on the vertical rod 3 can be adjusted.

[0030] Please refer to Figure 1, in one embodiment, preferably, the control mechanism includes a control box 4 fixed to the lower surface of the support platform 2. A movable control board 5 is installed in the control box 4. The end face of the control board 5 is connected to a telescopic member 6 that drives its movement. The telescopic member 6 is installed inside the control box 4. The telescopic member 6 is an electric telescopic rod. A transmission box 10 is installed in the control box 4. A moving member inserted into the transmission box 10 is installed on the end face of the control board 5. By setting the control mechanism, the clamping mechanism and the fixing component can be driven successively, thereby realizing the locking of the vertical rod 3 and the inclined rod 16, improving the convenience of the equipment during installation.

[0031] Specifically, the control box 4 is an airtight box body, and a flow guide pipe and a stabilizing pipe are respectively inserted on its surface. Inside the control box 4, a control board 5 that can cause the gas inside it to flow is installed. When the telescopic member 6 connected to the control board 5 expands and contracts, the control board 5 will move synchronously with the telescopic member 6. The transmission box 10 is fixed at the corner inside the control box 4. The control board 5 will drive the moving member to move synchronously and squeeze the gas inside the transmission box 10 to be discharged through the flow guide pipe and the stabilizing pipe, thereby completing the gas transmission.

[0032] Please refer to Figure 1 , in one embodiment, preferably, the inside of the transmission box 10 is divided into a first piston groove and a second piston groove by a partition. The first piston groove is connected to the closed cavity through a flow guide pipe, and the second piston groove is connected to the inside of the annular connection box 19 through a stabilizing pipe. Further, the inside of the transmission box 10 is divided into two areas by the partition, namely the first piston groove and the second piston groove, which respectively correspond to the flow guide pipe and the stabilizing pipe, and they are not related to each other, ensuring the gas transmission.

[0033] Please refer to Figure 1 , in one embodiment, preferably, the closed cavity is connected to the inside of the support pipe 21 through a gas guide pipe 12. The inner diameter of the support pipe 21 is equal to the outer diameter of the gas guide pipe 12, and a sealing ring is provided on the pipe wall at the connection of the gas guide pipe 12 and the support pipe 21. The air inside the first piston groove enters the inside of the closed cavity along the flow guide pipe, and then enters the inside of the support pipe 21 along the gas guide pipe 12, thereby completing the drive of the clamping plate 18. The gas guide pipe 12 is fixed to the connection seat 14 to ensure that the gas smoothly enters the inside of the support pipe 21 through the gas guide pipe 12 and then enters the inside of the inflatable cavity 15, forming a closed gas transmission channel.

[0034] Please refer to Figure 1, in one embodiment, preferably, the moving part includes a fixing rod 7 fixed to the end face of the control board 5. A first piston 8 adapted to the first piston groove is installed on the outer peripheral surface of the fixing rod 7. An opening is provided at the end of the fixing rod 7 away from the control board 5 for the sliding rod to be inserted. The sliding rod is connected to the inner wall of the fixing rod 7 by a spring. A second piston 9 adapted to the second piston groove is installed at the end of the sliding rod away from the spring. Further, by respectively squeezing the first piston groove and the second piston groove with the first piston 8 and the second piston 9, the flow of gas is realized.

[0035] Initially, the first piston 8 is located outside the first piston groove, and the second piston 9 is slidably connected and arranged inside the second piston groove. The telescopic member 6 drives the control board 5 to move, and the second piston 9 moves inside the second piston groove. The air located inside the second piston groove enters the inside of the clamping mechanism through the pressure stabilizing tube, completing the driving of the clamping mechanism. Subsequently, the first piston 8 enters the inside of the first piston groove, and the air located inside the first piston groove enters the inside of the fixing assembly along the diversion tube, realizing the driving of the fixing assembly.

[0036] Working principle and usage process of the present utility model: By setting up a support mechanism and cooperating with a clamping mechanism, rapid fixation of the cross bar 1, vertical rod 3, and diagonal rod 16 is achieved. The fixation method is simpler and faster, reducing the trouble of the traditional method that requires inserting a bolt and then hitting it with a hammer. It is also more convenient to disassemble. During installation, after the support platform 2 is sleeved on the outside of the vertical rod 3, the cross bar 1 is threadedly connected to the support platform 2, and the corresponding diagonal rod 16 is inserted into the inside of the connecting seat 14. The telescopic rod 6 drives the control board 5 to move, and the second piston 9 moves inside the second piston groove. The air inside the second piston groove enters the inside of the annular connection box 19 along the pressure stabilizing pipe and enters the inside of the fixed pipe 20 along the air pipe. Since the gas inside the fixed pipe 20 is in a saturated state, as long as a small amount of air enters, it can squeeze the locking piece to complete the clamping and fixation of the vertical rod 3. Subsequently, the first piston 8 enters the inside of the first piston groove. The air inside the first piston groove enters the inside of the connection groove along the connecting pipe and enters the inside of the support pipe 21 along the air guide pipe 12. The driving member drives the rack 22 to move, and the rack 22 cooperating with the gear can drive the support pipe 21 to rotate, thereby adjusting the angle of the connecting seat 14. By setting up a control mechanism, the driving of the clamping mechanism and the fixing component can be completed successively, thereby realizing the locking of the vertical rod 3 and the diagonal rod 16, improving the convenience of the equipment during installation. By setting up a fixing component, the driving member drives the rack 22 to move, and the rack 22 cooperating with the gear can drive the support pipe 21 to rotate, thereby adjusting the angle of the connecting seat 14. At the same time, the clamping plate 18 preliminarily limits the diagonal rod 16 under the drive of the spring. Since the gas inside the inflation cavity 15 is in a saturated state, as long as a small amount of air enters, it can squeeze the piston member to displace, and the piston member drives the clamping plate 18 to move, clamping and fixing the diagonal rod 16 located inside the connecting seat 14, ensuring the stability of the diagonal rod 16 after installation. All the components of the device used for gas transmission have good sealing effects and will not leak air.
