Summary of the invention
The object of the invention is to propose a kind of switching-in spring precompressed quantity regulating device that operating mechanism just can regulate switching-in spring precompressed amount that do not need to remove.
For addressing the above problem, the technical solution used in the present invention is:
A kind of switching-in spring precompressed quantity regulating device, comprise for being fixed at least two pillars on spring housing, described pillar extends along spring-compressed direction, on described pillar, be arranged with along the push pedal of pillar axes direction guiding movement, in described push pedal, be provided with at least two push rods, between push rod, leave on combined floodgate pull bar for locking the accommodation space of the locking nut of pressure spring plate, on described pillar, be provided with the locking structure for driving the driving mechanism that push pedal moves to compression switching-in spring direction along pillar axes and the rear defence thrust plate that puts in place for moving at switching-in spring to move to switching-in spring prolonging direction under the elastic force effect of switching-in spring.
Described pillar is that periphery is established threaded studdle, described driving mechanism be on studdle, arrange for the drive nut with studdle threaded engagement, described locking structure is the screw thread self-locking structure that studdle and drive nut form.
In described push pedal, offer for the jogger hole of push rod is installed, in push pedal, also symmetry offers two for installing the pillar hole of studdle, and described jogger hole is between two pillar holes.
Described push rod is that annular is distributed on 3 in push pedal.
The switching-in spring precompressed quantity regulating device that the present invention proposes, pillar in adjusting device is fixedly connected with spring housing, push pedal is sleeved on pillar, the driving mechanism arranging on pillar promotes push pedal campaign and drives the push rod arranging on it to promote pressure spring plate compression switching-in spring, until acting on combined floodgate pull bar, switching-in spring is disengaged for locking the power of the locking nut of pressure spring plate position, by locking structure, push pedal position is fixed, now just can turn locking nut, by adjusting locking nut, its axis direction along combined floodgate pull bar is moved, thereby adjust the position of pressure spring plate, finally realize the adjustment of the storage power of switching-in spring, after locking nut is adjusted to the right place, remove the locking of locking structure to push pedal, push pedal releases energy under the elastic force effect of switching-in spring, until pressure spring plate is pressed on the locking nut place after adjustment.Adjusting device of the present invention does not need to remove operating mechanism and just can directly to the decrement of switching-in spring, regulate, simple to operation, to increase work efficiency, adjusting device is simple in structure, be easy to carry, in operational environment, switching-in spring overhauled and debugged at the scene.
Further, pillar is set to screw rod, adopts the nut that can move up and down along screw rod arranging on screw rod to realize the promotion of push pedal and locking, makes the structure of adjusting device more simple, is easy to carry.
Further, be provided for installing the jogger hole of push rod in push pedal, push rod and push pedal releasable connection, be convenient to the replacing of push rod, reduces costs input, and versatility is good.
Further, adopt 3 uniform push rods of annular, make pressure spring plate stressed evenly, 3 push rods distribute ringwise, leave the accommodation space of locking nut between 3 push rods, are convenient to the adjusting of locking nut.
