[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] according to Figures 1-3 As shown, the system includes a base plate 1, a spring post 11 mounted on the top of the base plate 1, a top plate 12 mounted on the top of the spring post 11, a horizontal plate 13 mounted on one side of the side surface of the top plate 12, and a vertical plate 14 mounted on the other side of the side surface of the top plate 12. A protective cylinder 15 is mounted on the top of the base plate 1 near the outside of the spring post 11. The spring post 11 is located inside the protective cylinder 15, and the top of the protective cylinder 15 is installed with the bottom of the top plate 12. The protective cylinder 15 is specifically an elastic soft... The tube allows the protective cylinder 15 to have a certain degree of extensibility. Two sets of mounting plates 16 are installed on the four sides of the side surface of the base plate 1, and each mounting plate 16 has a through hole 17. The inside of the through hole 17 is movably screwed to the outer surface of the mounting bolt 18, and a nut 19 is movably screwed to one end of the outer surface of the mounting bolt 18. One end of the mounting bolt 18 passes through the threaded hole 21 into the inside of the fixing plate 2, and the mounting bolt 18 is movably screwed to the fixing plate 2 through the threaded hole 21.

[0023] The bottom end of the base plate 1 is installed with the inner wall of the bottom end of the mounting cavity 22, and the mounting cavity 22 is located inside the sofa cushion 23. The top end of the top plate 12 is fitted with the inner wall of the top end of the mounting cavity 22. Fixing plates 2 are installed at the top end of the mounting cavity 22 near the position between the two sets of mounting plates 16, and threaded holes 21 are opened inside the fixing plates 2. The sofa cushion 23 is installed on the top surface of one side of the sofa body 24.

[0024] The number of base plates 1 is several groups, and the several groups of base plates 1 are evenly distributed in an array on the bottom inner wall of the mounting cavity 22. The several groups of horizontally arranged top plates 12 are all connected by horizontal plates 13, and the several groups of vertically arranged top plates 12 are all connected by vertical plates 14.

[0025] Several sets of base plates 1 are evenly and arrayed in a rectangular shape inside the mounting cavity 22, and the bottom ends of the base plates 1 are installed against the inner wall of the bottom end of the mounting cavity 22. At the same time, two sets of mounting plates 16 installed on the four sides of the side surface of the base plates 1 are positioned on both sides of the fixing plate 2 installed on the inner wall of the bottom end of the mounting cavity 22. At this time, the inner surfaces of the two sets of mounting plates 16 are in contact with the outer surfaces of the fixing plate 2. The user can then use the mounting bolts 18 to secure the two sets of mounting plates 16 together. The plate 16 and the corresponding fixing plate 2 are screwed together. Afterwards, the user can screw the nut 19 onto one end of the outer surface of the mounting bolt 18, ensuring that the inner surface of the nut 19 is in contact with one side surface of the corresponding mounting plate 16. This allows several sets of base plates 1 to be installed on the bottom inner wall of the mounting cavity 22. Several sets of horizontally arranged top plates 12 are connected by horizontal plates 13, and several sets of vertically arranged top plates 12 are connected by vertical plates 14. For details, please refer to [reference needed]. Figure 2 As shown, since the top surfaces of several sets of top plates 12 are all fitted to the inner top wall of the sofa cushion 23, and the several sets of top plates 12 are connected to each other, when a user sits on the sofa body 24 and the sofa cushion 23, the several sets of spring columns 11 and the several sets of protective cylinders 15 will retract downward together as a whole, thereby playing a buffering role. This effectively avoids the situation where the existing spring columns 11 in the sofa are all single and single-point set, which makes it easy for a single point to dent when a user sits on the sofa during use.

[0026] 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.
