[0032] The following is combined with Figure 1-5 This application is described in further detail.
[0033] See also Figure 1-3 A classroom chair that is easy to disassemble comprises a seat cushion plate 1, on one side outer wall of the seat cushion plate 1 are fixedly installed two fixing seats 6, and connecting rods 2 are detachably installed in the two fixing seats 6, and the setting of the connecting rods 2 can play a role of auxiliary installation, and a backrest plate 3 is fixedly installed on the two connecting rods 2, and four supporting rods 4 are detachably installed at the bottom of the seat cushion plate 1, and the four supporting rods 4 are grouped in pairs, and support plates 5 are detachably installed at the bottom of the two groups of support rods 4, and an installation box 8 is fixedly installed on the bottom outer wall of the seat cushion plate 1, and the setting of the installation box 8 can play a role of auxiliary installation, and a disassembly mechanism is arranged in the installation box 8; and the disassembly mechanism can play a role of disassembly.
[0034] The disassembly mechanism includes a screw 9, which is rotatably installed on an inner wall of one side of the installation box 8, and the screw 9 is a bidirectional screw. Four connecting blocks 7 are fixedly installed at the bottom of the cushion plate 1, and the four connecting blocks 7 are arranged one by one corresponding to the four support rods 4. Two threaded plates 10 are symmetrically screwed on the screw 9. By setting the screw 9, the two threaded plates 10 can be driven to approach each other or approach each other. Two clamping columns 12 are symmetrically fixedly installed on the outer wall of one side where the two threaded plates 10 are close to each other. A clamping groove 11 is opened on the outer wall of one side of the four support rods 4 and the corresponding connecting block 7. The clamping columns 12 are respectively slidably installed in the four clamping grooves 11. One end of the screw 9 passes through the outer wall of one side of the installation box 8 and is fixedly installed with a limit knob 13.
[0035] When in use, by turning the limit knob 13, the limit knob 13 will rotate, thereby driving the screw rod 9 to rotate as well. The rotation of the screw rod 9 will drive the two threaded plates 10 to approach each other. The two threaded plates 10 approaching each other will drive the two symmetrical clamping columns 12 to approach each other, thereby releasing the connection between the seat cushion plate 1 and the four support rods 4, facilitating quick disassembly.
[0036] Reference Figure 2 and Figure 3The outer walls on both sides of the installation box 8 are provided with the same sliding groove 16, and the two threaded plates 10 are slidably installed in the sliding groove 16. By setting the sliding groove 16, the threaded plate 10 can be slidably installed, thereby playing the role of auxiliary limit.
[0037] Reference Figure 2 The outer wall of one side of the two threaded plates 10 is provided with a same limiting hole 14, and a limiting column 15 is slidably installed in the limiting hole 14, and the two ends of the limiting column 15 are respectively fixedly installed on the inner walls of the two sides of the installation box 8. By setting the limiting hole 14, the limiting column 15 can be slidably installed inside, and can play an auxiliary limiting role.
[0038] Reference Figure 1 and Figure 4 The outer wall of one side of the fixing seat 6 and the connecting rod 2 is penetrated with the same circular hole 17, and a circular column 18 is slidably installed in the circular hole 17. By providing the circular hole 17, the circular column 18 can be slidably installed therein, thereby playing a role of auxiliary installation.
[0039] Reference Figure 4 , threads 19 are provided on both sides of the outer surface of the circular column 18, and nuts 20 are screwed on the two threads 19. By rotating the two nuts 20 and turning them down, the restriction on the circular column 18 can be released, so that the circular column 18 can be removed, and then the disassembly between the cushion plate 1 and the backrest plate 3 can be completed.
[0040] Reference Figure 4 The two nuts 20 are respectively located on the outer wall of one side of the fixing seat 6 close to each other and contact with it. By arranging the two nuts 20 to be respectively located on the outer wall of one side of the fixing seat 6 close to each other, the auxiliary abutment effect can be played.
[0041] Reference Figure 5 A mounting block 21 is fixedly mounted on the outer wall of one side of the support rod 4, and a threaded hole 22 is provided on the mounting block 21. A fixing bolt 23 is screwed into the threaded hole 22, and a fixing knob 24 is fixedly mounted on one end of the top of the fixing bolt 23. By turning the fixing knob 24, the fixing knob 24 rotates, which drives the fixing bolt 23 to rotate and move upward, thereby releasing the connection between the support rod 4 and the support plate 5, and then the multiple positions of the chair can be disassembled, and after disassembly, each component is easy to carry and organize, reducing the volume of the chair, and the space occupied by the chair as a whole is smaller, which is more convenient.
[0042] Reference Figure 5 The bottom end of the fixing bolt 23 is threadedly connected to the top of the support plate 5, and an anti-skid pad is sleeved on the fixing knob 24. The friction force can be increased by arranging the anti-skid pad.
[0043] The implementation principle of the present application is as follows: when in use, firstly, by rotating the two nuts 20, and then rotating the two nuts 20 down, the restriction on the circular column 18 can be released, so that the circular column 18 can be removed, and then the disassembly between the seat cushion plate 1 and the backrest plate 3 can be completed;
[0044] By rotating the limit knob 13, the limit knob 13 rotates, thereby driving the screw rod 9 to rotate, and the screw rod 9 rotates, thereby driving the two threaded plates 10 to approach each other, and the two threaded plates 10 approach each other, thereby driving the two symmetrical clamping columns 12 to approach each other, thereby releasing the connection between the cushion plate 1 and the four support rods 4;
[0045] Then, by turning the fixing knob 24, the fixing knob 24 will drive the fixing bolt 23 to rotate and move upward, so that the connection between the support rod 4 and the support plate 5 can be released, and then the multiple positions of the chair can be disassembled, and after disassembly, each component is easy to carry and organize, reducing the size of the chair, and the space occupied by the entire chair is smaller, which is more convenient.
