All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0016] Please see Figures 1 to 4 This utility model provides a technical solution: an adjustable column base corner protector that is not easy to fall off, comprising: four corner protector plates 1, the corner protector plates 1 are L-shaped, the four corner protector plates 1 are attached to the four corners of the lower end of the column to protect the four corners of the column, the height of the corner protector plates 1 is 90CM-120CM, and the specific length can be adjusted according to actual needs.
[0017] Connecting plates 2 are fixedly installed on the upper and lower sides of both ends of the corner guard plate 1. The connecting plates 2 are L-shaped. One end of the connecting plates 2 is provided with a round hole 4 and a strip hole 5. The strip hole 5 and the round hole 4 are connected. The inner diameter of the round hole 4 is larger than the width of the strip hole 5. The other end of the connecting plates 2 is fixed to the outer wall of the corner guard plate 1, and a reinforcing plate 3 is fixedly installed at the connection between the connecting plates 2 and the corner guard plate 1 to reinforce the connection between the connecting plates 2 and the corner guard plate 1.
[0018] Two sets of fixing components are provided between each pair of adjacent corner guard plates 1. Each set of fixing components includes two threaded cylinders 6 and one threaded rod 7. The threads at both ends of the threaded rod 7 are symmetrically arranged, and the two ends of the threaded rod 7 are respectively threaded to the inner walls of the two threaded cylinders 6. By rotating the threaded rod 7, the two threaded cylinders 6 can be driven to move inward or outward simultaneously. The end of the threaded cylinder 6 away from the threaded rod 7 is connected to the connecting plate 1 2. The connecting plate 2 8 is fixedly installed at the end of the threaded cylinder 6 away from the threaded rod 7. A cylinder 9 is fixedly installed at the other end of the connecting plate 8. A baffle 10 is fixedly installed at the outer end of the cylinder 9. The diameter of the cylinder 9 is smaller than the width of the slot 5, and the diameter of the baffle 10 is larger than the width of the slot 5 but smaller than the diameter of the round hole 4. By passing the baffle 10 and the cylinder 9 through the round hole 4, and then pulling the connecting plate 8 and the threaded cylinder 6, the cylinder 9 slides into the slot 5. Then, by rotating the threaded rod 7, the threaded cylinder 6 is fixed, and the cylinder 9 is fixed in the slot 5, thereby fixing the corner guard plate 1 to the column.

Fixing bolts 15 are inserted into the through holes 12. More specifically, after the threaded cylinder 6 is fixed, the fixing bolts 15 are passed through the through holes 12 on the first fixing ring 11 and the second fixing ring 14 and then screwed on the nuts, thereby fixing the first fixing ring 11 and the second fixing ring 14, preventing the threaded rod 7 from loosening after long-term use, which would cause the corner guard plate 1 to loosen.
[0021] When this device is in operation, the corner guard 1 is attached to the corner of the bottom of the column. Then, the baffle 10 and the cylinder 9 are passed through the circular hole 4. Then, the connecting plate 8 and the threaded cylinder 6 are pulled to allow the cylinder 9 to slide into the slotted hole 5. Then, the wrench and the drive block 13 are connected, and the drive block 13 and the threaded rod 7 are driven to rotate, fixing the threaded cylinder 6. At the same time, the cylinder 9 is fixed in the slotted hole 5, thereby fixing the corner guard 1 to the column. Finally, the fixing bolt 15 is passed through the through hole 12 on the fixing ring 11 and the fixing ring 2 14 and the nut is screwed on, thereby fixing the fixing ring 11 and the fixing ring 2 14, preventing the threaded rod 7 from loosening after long-term use, which would cause the corner guard 1 to loosen.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
