DETAILED DESCRIPTION

[0017] like Figures 1 to 6 A floor spring includes a body shell 10, in which a transmission shaft 20, a power assembly 30 and a speed regulating assembly 40 are provided. A cam 21 is provided in the transmission shaft 20, and the cam 21 has a positioning portion 22 and an arc portion 23. The power assembly 30 is provided on one side of the positioning portion 22, and the speed regulating assembly 40 is provided on one side of the arc portion 23.

[0018] The power assembly 30 includes a power transmission spring 31, a power piston 32 and a tail cover 33. One end of the power transmission spring 31 abuts against the power piston 32 and the other end abuts against the tail cover 33. The other end of the power piston 32 abuts against the positioning portion 22 of the transmission shaft 20. The speed regulating assembly 40 includes a speed regulating piston 41, a speed regulating spring 42 and an end cover 43. A speed regulating component 44 is threadedly connected to the speed regulating component 44. One end of the speed regulating spring 42 abuts against the speed regulating component 44 and the other end abuts against the end cover 43. One end of the speed regulating piston 41 abuts against the arc portion 23.

[0019] During specific implementation, the mounting groove 102 of the body shell 10 is fixedly connected to the glass door leaf by bolts. When the door leaf is opened, the transmission shaft 20 rotates, and the speed regulating piston 41 pushes the door leaf to expand through the speed regulating spring 42. The power piston 32 pushes the door leaf to reset through the power transmission spring 31. By adjusting the position of the speed regulating component 44 on the speed regulating piston 41, the elastic force of the piston spring 42 can be adjusted, thereby adjusting the opening and closing speed of the door leaf.

[0020] A snap ring 103 is provided at the end of the mounting channel 101 of the body shell 10. The inner diameter of the snap ring 103 is slightly smaller than the inner diameter of the mounting channel 101. When the power assembly 30 is installed in the mounting channel 101 of the body shell 10, a snap spring 104 is provided on one side of the tail cover 33, and the power assembly 30 is fixedly installed in the body shell 10 through the snap spring 104.

[0021] A sealing ring 105 is provided between the outer periphery of the tail cover 33 and the end cover 43 and the inner wall of the installation channel 101 . The sealing ring 105 can prevent foreign matter from entering the interior of the installation channel 101 .
