Cam is coaxially connected with handle, and capable rotation is rotated into handle, when rotation handle makes cam to horizontal level, cam extrusion two
A pawl makes two pawls be separated with the ratchet on ratchet, and ratchet realization is two-way to be rotated freely, convenient that height of seat is adjusted
Section.
Operation principle：For the utility model under the action of secondary spring, seat can realize automatic up-regulating function, work as driver
When needing to adjust height of seat and suspension amount, leaf spring rotation or locking are controlled by ratchet adjusting mechanism；Work as ratchet adjustable
When organization switch is opened, corresponding leaf spring can be along ratchet central rotation, and the leaf spring does not generate drag at this time, can
Arbitrarily the height of seat to be adjusted；When ratchet adjustable, which switchs, closes, corresponding leaf spring is in lockup state,
The height of seat is locked, and flexible deformation occurs by connecting rod compression steel plate spring at this time, generates drag, realizes the suspension work(of seat
Energy；The machinery lofty tone suspension system adjusts the leaf spring of different-stiffness using two groups of ratchet adjusting mechanisms respectively, makes it right
When the height of seat is adjusted, the suspension function of 3 kinds of different sections drags can be combined into, so as to meet different weight driver
Demand.
The advantages of the utility model and good effect：
（1）Lofty tone suspension system provided by the utility model is using leaf spring and ratchet adjusting mechanism instead of tension spring and in advance
Tight adjusting mechanism by leaf spring various combination, matches out a rational suspension amount for different section weight drivers, carries
High driver comfort, effectively solves the problems, such as present in background technology.
（2）When lofty tone suspension system provided by the utility model adjusts height of seat, by the way that tension spring is aided in realize seat certainly
Dynamic up-regulating function, then by adjusting of the outdoor handle realization of rotating ratchet adjusting mechanism to height of seat, operating force is small, the time
It is short, simple operation is improved, and also the machinery lofty tone suspension system overall structure is simple, and install compact, more lightweight can be big
It is big to reduce manufacture cost.
（3）Machinery lofty tone suspension system provided by the utility model meets the driver of wider weight, suitable for institute
There is the automotive seat of suspension vibration damping demand, the scope of application is wider.
