Embodiment 1
[0020] Example 1, such as Figure 1 ~ Figure 4 As shown, this embodiment aims to solve the technical problems existing in the existing learning chair lifting device. The control object of the control system in this embodiment is the lifting structure of the lockable air rod, and the seat height can be controlled by controlling the solenoid valve. example.
[0021] For this reason, the gas spring lifting mechanism provided in this embodiment includes a column 3 and an inner tube 2 sleeved in the column 3, and the telescopic connection between the inner tube 2 and the column 3, so that the inner tube 2 and the column 3 The structure design of the existing common telescopic rod is formed. In order to realize the automatic expansion and contraction between the inner tube 2 and the column 3, a lockable gas spring 6 is set inside the inner tube 2, wherein the fixed end of the lockable gas spring 6 is connected to the The inner tubes 2 are fixedly connected, the power end of the loc...
Embodiment approach 1
[0027] Implementation method 1: When the battery is short of power or a certain component of the control system fails, you can manually press the button 19 to open the thin rod of the piston rod that opens the lockable gas spring 6. Under the force of the locking gas spring, the seat rises under the drive of the column 3; if the seat height is at a high level, the column 3 can be pressed down and moved to a suitable seat height by hand or leg pressure.
[0028] Implementation method 2: B2 can be pulled up through the handshake of the switch flexible plate 11, so that when the switch flexible plate 11 opens the piston rod thin rod of the lockable gas spring 6, if the seat height is at a low position, under the thrust of the lockable gas spring 6 The chair seat rises under the drive of the column 3; if the seat height is at a high position, the column 3 can be pressed down by hand or leg pressure to move to a suitable seat height.
[0029] In this embodiment, the working princip...
