[0017] REFERENCE Figures 1 to 5 :
[0018] The utility model provides a bottom disc structure for a reclining chair, comprising a bottom disc 1 and a locking structure 2, the locking structure 2 is connected with the bottom disc 1, the bottom disc 1 comprises a chair connecting system 11 and a reclining system 12 arranged from outside to inside, the locking structure 2 comprises a reclining locking system 21, a locking positioning system 22 and a chair fixing system 23, one end of the reclining locking system 21 is connected with the locking positioning system 22 and the chair fixing system 23 respectively, the other end is connected with the reclining system 12, and the chair fixing system 23 is further connected with the chair connecting system 11.
[0019] Because the chair connecting system 11 comprises a cushion supporting piece 13, a back supporting piece 14 and a foot supporting piece 15, the cushion supporting piece 13 is connected with the back supporting piece 14 at the rear end, the foot supporting piece 15 is connected with the back supporting piece 14 at the bottom, and the cushion supporting piece 13 and the foot supporting piece 15 are connected, so when a user uses the utility model, the chair cushion, back cushion and rubber pad required by the user can be connected through the use of the cushion supporting piece 13, the back supporting piece 14 and the foot supporting piece 15, so as to meet the use requirement of the user.
[0020] Because the chair fixing system 23 includes the fixing frame 231, the fixing shaft 232 and the linkage piece 233, the fixing shaft 232 is arranged in the fixing frame 231, one end of the fixing shaft 232 is connected with the free locking system 21 through the linkage piece 233, the other end is matched with the back supporting piece 14, the free locking system 21 includes the locking fixing frame 211, the locking spring 212 and the locking shaft 213, the locking spring 212 and the locking shaft 213 are arranged from outside to inside in the locking fixing frame 211, one end of the locking shaft 213 is matched with the free system 12, the other end is matched with the locking positioning system 22, the locking shaft 213 also includes the limiting piece 2131 arranged outside, one end of the locking spring 212 is abutted with the limiting piece 2131, the other end is abutted with the inner wall of the locking fixing frame 211, so when the user uses the utility model, through the driving of the locking positioning system 22, the locking shaft 213 is driven to move to the direction of the back supporting piece 14, the force driven in real time will make the locking spring 212 compressed, and the fixing shaft 232 is driven to move to the direction of the back supporting piece 14 in real time through the linkage piece 233, the end of the fixing shaft 232 will be inserted into the inside of the back supporting piece 14 and matched with it, so that the position of the back supporting piece 14 is fixed, and through the mutual connection relationship among the cushion supporting piece 13, the back supporting piece 14 and the foot supporting piece 15, the positions of the cushion supporting piece 13 and the foot supporting piece 15 are also fixed, on the contrary, when the driving of the locking positioning system 22 stops, the locking shaft 213 will lose the force driven by the locking positioning system 22, the locking spring 212 will be restored in real time, so that the locking shaft 213 is reset to the opposite direction of the back supporting piece 14, so that the locking shaft 213 will be inserted into the free system 12, at this time, the fixing shaft 232 will be separated from the fixed cooperation inside the back supporting piece 14 in real time, and the user can adjust and use the cushion supporting piece 13, the back supporting piece 14 and the foot supporting piece 15 in real time.
[0021] Because the said free system 12 includes lifting part 121 and free part 122, the said lifting part 121 and free part 122 are movably connected, the said free part 122 includes free buffer 123 and free lock slot 124, the said free buffer 123 is set inside the free part 122, the said free lock slot 124 is opened outside the free part 122 and cooperates with the locking shaft 213, so when the user uses the utility model, when the said locking shaft 213 is not inserted into the free lock slot 124 and cooperates with it, at this time the user can ride on the utility model equipped with the cushion to swing "freely", and at this time the said chair connecting system 11 cannot be adjusted, on the contrary when the said locking shaft 213 is inserted into the free lock slot 124 and cooperates with it, the user cannot swing "freely" on the utility model equipped with the cushion in real time, but the said chair connecting system 11 can be adjusted, and because the said lifting part 121 and free part 122 are movably connected, they are not fixedly connected and can move independently, so the user can adjust the height of the chair equipped with the utility model without affecting the user's need of swinging "freely".
[0022] When the user uses the utility model, the user installs the chair leg structure in the lifting part 121, and then connects the chair cushion and other accessories in the chair connecting system 11 part, so that a "free" chair is formed, when the user needs to swing "freely", the locking shaft 213 of the free locking system 21 is driven away from the free lock slot 124 by driving the locking positioning system 22, at this time the free part 122 is not fixed by the locking shaft 213, the user can swing "freely" on the chair equipped with the utility model structure in real time, on the contrary it cannot swing "freely", and when the user needs to swing "freely" or not, because the said lifting part 121 and free part 122 are movably connected, they are not fixedly connected and can move independently, the chair leg installed on the utility model can be adjusted in height at will without affecting the use.
[0023] When the user uses the utility model, through the use of the free buffer 123, when the user rides on the free chair equipped with the utility model structure to swing "freely", it can prevent the lifting part 121 and the free part 122 from being damaged due to direct contact and collision because the swing amplitude is too large when swinging "freely".
