Content of the invention
The purpose of the present invention is to propose to a kind of be not required to remove what operating mechanism just can be adjusted to switching-in spring precompressed amount
Switching-in spring precompressed quantity regulating device.
For solving the above problems, the technical solution used in the present invention is：
A kind of switching-in spring precompressed quantity regulating device, including at least two pillars for being fixed on spring housing, institute
State pillar to extend along spring-compressed direction, described pillar is arranged with the push pedal along pillar axes direction guiding movement, described push away
At least two push rods are provided with plate, leave between push rod and be used on combined floodgate pull bar locking the accommodating sky of the locking nut of pressure spring plate
Between, described pillar is provided with for driving push pedal along pillar axes to the compression drive mechanism moved of switching-in spring direction and use
Put what rear defence thrust plate moved to switching-in spring prolonging direction under the elastic force effect of switching-in spring in place in moving in switching-in spring
Locking structure.
Described pillar sets threaded studdle for periphery, described drive mechanism be studdle on setting for
The drive nut of studdle screw thread cooperation, described locking structure is the screw thread self-locking knot of studdle and drive nut composition
Structure.
Jogger hole for installing push rod is offered on described push pedal, push pedal also symmetrically offers two and is used for installing
The pillar hole of support screw rod, described jogger hole is located between two pillar holes.
Described push rod is 3 that annular is distributed in push pedal.
Switching-in spring precompressed quantity regulating device proposed by the present invention, the pillar in adjusting means is fixing with spring housing even
Connect, push pedal is sleeved on pillar, on pillar, the drive mechanism of setting promotes push pedal campaign to drive the push rod arranging thereon to promote pressure
Spring plank compresses switching-in spring, until switching-in spring acts on being used on combined floodgate pull bar locking the power of the locking nut of stage clip Board position
Be released from, by locking structure, push pedal position fixed, now just can turn locking nut, by adjust locking nut make its edge
The axis direction of combined floodgate pull bar moves, thus adjusting the position of pressure spring plate, finally realizes the adjustment of the storage energy of switching-in spring,
After locking nut is adjusted in place, release the locking to push pedal for the locking structure, push pedal discharges under the elastic force effect of switching-in spring
Energy, until at pressure spring plate compression locking nut after the adjustment.The adjusting means of the present invention does not need to remove operating mechanism just
Directly the decrement of switching-in spring can be adjusted, simple to operation, improve work efficiency, adjusting means structure is simple,
It is easy to carry, switching-in spring can be overhauled in working environment at the scene and debug.
Further, pillar is set to screw rod, using the nut realization that can move up and down along screw rod of setting on screw rod
Promotion to push pedal and locking, the structure making adjusting means is simpler, be easy to carry.
Further, push pedal is provided for installing the jogger hole of push rod, push rod and push pedal releasable connection, is easy to push rod
Replacing, reduces cost puts into, and versatility is good.
Further, using 3 push rods that annular is uniform, make pressure spring plate uniform force, 3 push rods are ringwise distributed, 3
Leave the accommodation space of locking nut between push rod, be easy to the regulation of locking nut.
Brief description
Fig. 1 is a kind of structural representation of the embodiment of switching-in spring precompressed quantity regulating device of the present invention；
Fig. 2 is a kind of use state figure of the embodiment of switching-in spring precompressed quantity regulating device of the present invention.
Specific embodiment
A kind of embodiment of the switching-in spring precompressed quantity regulating device of the present invention：As shown in Fig. 1～Fig. 2, this switching-in spring
Precompressed quantity regulating device includes the pillar for being fixedly connected with the spring housing 21 of switching-in spring 1, and two pillars are symmetrical arranged
In spring housing both sides, each pillar extends along compression switching-in spring direction, and two pillars are provided with externally threaded for outer peripheral face
Support screw rod 6, studdle is arranged with push pedal 7, studdle 6 is installed with for driving push pedal 7 to compression switching-in spring 1 one
The drive nut 8 of side shifting, push pedal 7 is threaded with three push rods 4 between two studdles 6, and three push rods 4 circularize
It is distributed in push pedal, between three push rods 4, leave the locking nut 5 for locking stage clip Board position placed on combined floodgate pull bar 2
Accommodation space, three push rods 4 are used for the pressure spring plate 3 in switching-in spring 1 for the top pressure, and three push rods 4 are in the effect of drive nut 8
Under can with push pedal 7 to compression switching-in spring 1 one side shifting.
When using, by two studdles 6, two hanger rings 22 with spring housing 21 outside of tripping spring respectively
Connected using screw threads for fastening, make the uniform top pressure of three push rods 4 on pressure spring plate 3 and guarantee that three push rods are distributed in combined floodgate pull bar week
