Step guarantees functional reliability.Hook portion and mounting portion are integrally formed as linking up with, and ensure that the fastness and reliability of hook.
This is as described below using the working principle of the mechanical loose card device of service speed control:
When pedal is in initial position, pedal position is parallel with pedestal, and hanging scroll is located at the top of card slot, i.e. this utilization operates
The mechanical loose card device of speed control is in releasing orientation;
After pedal position is pushed, pedal position is rotated around the second shaft.After hanging scroll and hook contact, in the effect of lower pressure
Under, continue to push pedal position, even pedal position continues to rotate around the second shaft, and link up with also under the action of hanging scroll, around first
Shaft rotation.And card slot is fallen into after the bevel edge that hanging scroll slips over hook portion, come up pedal position at this time, by the effect of tension spring
Power, hanging scroll, which slowly rises, slides into card slot slot bottom, and hanging scroll and card slot are in clamped condition at this time, i.e., this utilizes service speed control
Mechanical pine card device is in locking state.
When pushing pedal position again, until pedal position is pressed down to extreme position, hanging scroll skids off card slot at this time, at this time:
If slowly unloading lower pressure, that is, the lower pressure for the pedal position that comes up, hanging scroll is again slowly along the edge of hook portion
Rise and slide into card slot, is clamped again with card slot;
If moment unloads lower pressure, i.e., pedal position is quickly unclamped, since the coefficient of elasticity of tension spring is greater than the elasticity system of torsional spring
Number, then the reset speed of hanging scroll is greater than the reset speed of hook, therefore before hook resets, hook has risen above card slot
Position, and continue to rise and be returned to original state.
This controls this using the state of the mechanical loose card device of service speed control, operation using different service speeds
Simply, convenient and practical, and high reliablity.
Above-mentioned specific embodiment is the preferred embodiment of the present invention, can not be limited the invention, and others are appointed
The change or other equivalent substitute modes what is made without departing from technical solution of the present invention, are included in protection of the invention
Within the scope of.
