In addition, it is also widely used in the advertising industry, municipal administration, transportation roads and bridges, mining and other departments.

[0003] The scaffolding adopts rigid fixed connection, and construction workers need to use independent steel pipes to build it at the construction site. Both construction and dismantling require tools. Some use fasteners to install and fix the steel pipes and pedals. The installation of steel pipes and pedals requires multiple fasteners. The installation and fixation of steel pipes and pedals need to be carried out separately, which is slow and inefficient, affecting the construction progress, so it needs to be improved.

Obviously, the described embodiments are only part of the embodiments of the present application, not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0029] Please refer to Figures 1 to 6 ​The present invention provides a technical solution: a socket-type disc-type scaffold, comprising a plurality of columns 1, the top of the column 1 is fixedly connected to a plug rod 2, the bottom end of the column 1 is provided with a slot adapted to the plug rod 2, the column 1 is fixedly sleeved with two limiting rings 3, and a connecting ring 4 is sleeved between the two limiting rings 3, a supporting cross bar 5 is fixedly connected between two adjacent connecting rings 4, a locking assembly is provided in the supporting cross bar 5, the locking assembly is inserted into the slot and the plug rod 2 to lock the upper and lower columns 1, and pedals 6 are provided in the four supporting cross bars 5.

[0030] Furthermore, the connecting ring 4 and the supporting cross bar 5 are formed as an integral structure, and the stability of the relevant structure is increased by the setting of the integral structure.

[0031] Furthermore, the locking assembly includes slideways opened in the left and right ends of the supporting cross bar 5, and a locking rod 7 is slidably arranged in the slideway. The inner wall of the slot and the insertion rod 2 are both provided with locking grooves adapted to the locking rod 7.

[0032] First, put the connecting ring 4 on the top of the column 1, and then insert another column 1 above and below, so that the connecting ring 4 is located between the two limit rings 3, which plays a role in horizontal fixing of the supporting cross bar 5, thereby improving the lateral tensile strength of the supporting cross bar 5, and when the locking rod 7 is inserted into the locking groove, the upper and lower columns 1 can be locked and fixed.

[0033] Furthermore, a thrust assembly is provided on the lower surface of the support crossbar 5, and the thrust assembly is used to push the two locking rods 7 into the locking grooves.

[0034] When the connecting ring 4 is sleeved between the two limit rings 3, under the action of the thrust assembly, the two locking rods 7 can be pushed into the locking grooves, thereby realizing the installation and fixation of the upper and lower columns 1. Moreover, since the connecting ring 4 is provided with supporting cross bars 5 in the left and right directions and the front and back directions, the upper and lower columns 1 can be locked and fixed from two directions, the left and right directions or the front and back directions, making the connection between the upper and lower columns 1 more stable and firm.

[0035] Furthermore, the thrust assembly includes a screw rod 8 rotatably connected to the support cross bar 5 through a bearing seat, a screw sleeve 9 is threadedly connected to the screw rod 8, and a connecting rod 10 is hinged between the screw sleeve 9 and the locking rod 7.

[0036] When it is necessary to push the locking rod 7 into the locking groove through the thrust assembly, the screw rod 8 is rotated. Since the screw rod 8 is threadedly connected to the screw sleeve 9, and the rotation of the screw sleeve 9 is restricted by the connecting rod 10 and the locking rod 7, the screw sleeve 9 can move up on the surface of the screw rod 8. Under the action of the two connecting rods 10, the two locking rods 7 will be pushed away from each other, so that the two locking rods 7 can be inserted into the locking groove at the same time, thereby improving operational efficiency.

[0037] Further, the locking rod 7 is fixedly connected with a sliding block 11, the support cross rod 5 is provided with a through slot for the sliding block 11 to move, one end of the connecting rod 10 is hinged to the support cross rod 5, and the other end is hinged to the screw sleeve 9.

[0038] Through the arrangement of the through slot, the connecting rod 10 can push the sliding block 11 to move in the through slot, so that the sliding block 11 can push the locking rod 7 to insert into the locking slot.

[0039] Further, the pedal 6 is fixedly connected with a hanging plate 12 which is hung on the support cross rod 5, and through the arrangement of the hanging plate 12, the pedal 6 can be preliminarily hung on the support cross rod 5.

[0040] Further, the support cross rod 5 is internally provided with a cavity, and the cavity is provided with a positioning assembly which penetrates the hanging plate 12 and penetrates into the pedal 6, and through the arrangement of the positioning assembly, the pedal 6 is fixed, so that the pedal 6 can be more stably and firmly located on the support cross rod 5.

[0041] Further, the positioning assembly comprises a side T-shaped positioning rod 13 which is slidingly arranged in the cavity, the hanging plate 12 and the pedal 6 are provided with a positioning slot which is matched with the side T-shaped positioning rod 13, and the cavity is fixedly provided with a spring 14 which is used to push the side T-shaped positioning rod 13 to insert into the positioning slot.

[0042] Further, the support cross rod 5 is fixedly provided with two fixed plates 15, the two fixed plates 15 are fixedly connected with a guide rope wheel 16, the guide rope wheel 16 is provided with a pull rope 17, one end of the pull rope 17 penetrates into the cavity and is connected with the side T-shaped positioning rod 13, and the other end of the pull rope 17 is connected with the screw sleeve 9.

[0043] When the screw sleeve 9 moves upward to push the two locking rods 7 to insert into the locking slots, the screw rod 8 moves upward to release the traction of the pull rope 17, and under the action of the elasticity of the spring 14, the side T-shaped positioning rod 13 is pushed to insert into the positioning slot, so that the pedal 6 is installed and fixed.

[0044] When the stand 1 and the pedal 6 need to be disassembled, the screw rod 8 is rotated to move the screw sleeve 9 downward, the screw sleeve 9 moves downward to pull the two locking rods 7 to move into the sliding groove, so that the locking rod 7 and the locking slot are separated from each other, and the stand 1 located above can be pulled upward to realize the disassembly of the stand 1, and at the same time, the screw sleeve 9 moves downward to pull the pull rope 17 to move downward, and under the reversing action of the guide rope wheel 16, the pull rope 17 moves downward to overcome the elasticity of the spring 14 to pull the side T-shaped positioning rod 13 to shrink into the cavity, so that the side T-shaped positioning rod 13 and the positioning slot are separated from each other, and the pedal 6 is fixed, and then the pedal 6 can be removed.

[0045] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
