The locking frictional force between eccentric wheel and piston rod can be increased.
The newly-increased parts on the basis of existing checking cylinder of the present invention and original parts can form following three kinds of works
With mechanism, as depicted in figs. 1 and 2：
First, diaphragm type cylinder mechanism mainly includes diaphragm cylinder cap 11, film 12, pallet 13, push rod 14, diaphragm cylinder spring
21 and joint 25, main unblock thrust is provided, after diaphragm type cylinder fills wind, push rod 14 can promote balancing lever 22 to drive screw rod 15
Mobile, so that above-mentioned two eccentric wheel is swung and be in solution lock-bit, now piston rod 4 is not locked, and recruitment made by locking type checking cylinder
Condition is identical with general brake cylinder.
Second, screw rod eccentric mechanism mainly include the first screw rod 15, the second screw rod 29, bearing 16, the first eccentric wheel 17,
Second eccentric wheel 28 and bearing 18, the main function that latching ram bar is provided, pass through between eccentric wheel and corresponding screw rod non-from
Lock trapezoidal thread connects, and screw rod axial movement may result in corresponding eccentric wheel to swing, when eccentric wheel swings clamping piston bar 4 tapered sleeve
After 4.1, can latching ram bar 4, so that checking cylinder brake force is persistently kept.
Third, manual draw bar mechanism mainly includes hand lever 19, manual draw bar 20, backing plate 23 and locking spring 24, main
Manual unlocking function is provided, when vehicle is under the operating mode of no wind regime, manual draw bar 20 can be pulled, manually lever 19 drives

Bar 4 return back to cylinder body 1 bottom, complete incidence graph after checking cylinder braking.
Again as shown in figure 3 to figure 7, the specific work process of the railway freight-car locking type sealed brake cylinder of the present invention is as follows：
When locking operating mode：
After emergency brake of vehicle, after the setting locking that brake pipe's pressure is less than parking braking control valve starts pressure,
Pressure air in diaphragm type cylinder is discharged, and locking spring 24 drives hand lever 19 to promote the first screw rod 15 and the second screw rod 29
Mobile, make the first eccentric wheel 17 and the second eccentric wheel 28 swing the tapered sleeve 4.1 of clamping piston bar 4, thus latching ram bar 4.
When pneumatic unblock operating mode：
After vehicle fills wind alleviation, after the setting unblock that brake pipe's pressure is higher than parking braking control valve starts pressure,
Brake pipe's pressure air enters diaphragm type cylinder, and push rod 14 stretches out, and drives balancing lever 22 to promote the first screw rod 15 and the second spiral shell
Bar 29 is mobile, makes the first eccentric wheel 17 and the second eccentric wheel 28 swing the tapered sleeve 4.1 of no longer clamping piston bar 4, thus unlocking work
Stopper rod 4.
When manual unlocking operating mode：
It is also possible to pull manual draw bar 20 after first eccentric wheel 17 and the second eccentric wheel 28 latching ram bar 4, drive manually
Lever 19 pulls the first screw rod 15 and the second screw rod 29 mobile, so that the first eccentric wheel 17 and the second eccentric wheel 28 is swung and no longer compress
The tapered sleeve 4.1 of piston rod 4, thus unlock piston rod 4.
The content that this specification is not described in detail belongs to prior art known to professional and technical personnel in the field.
Finally it should be noted that above specific embodiment is only in order to illustrate technical scheme rather than it is limited
System, although being described in detail to the present invention with reference to preferred embodiment, it should be understood by one skilled in the art that to this
The technical scheme of invention is simply changed or equivalent, such as, according to checking cylinder actual design needs, may also be employed
The first half of described piston rod 4 cancels the tapered sleeve 4.1 of overcoat, still can reach certain locking effect；Or, adopt
Bearing 18 design screw rod fairlead and increase bearing, can reach the effect increasing the first screw rod 15 and the second screw rod 29 travelling performance
Really.These are all without departing from the spirit and scope of technical solution of the present invention, and all should cover the protection in the claims in the present invention
Among scope.
