Putting push pedal that cylinder is slidably matched and be fixed on the pressurize pin on release cylinder barrel, described release cylinder communicates with combustion gas cavity；
Described brake assemblies includes the bolt stay cord in described push pedal Yu combustion gas cavity inner wall.
Further, described push pedal is provided with draw ring, the inwall of described combustion gas cavity is provided with retainer ring, described in draw
The two ends of rope are separately fixed in described draw ring and retainer ring.
Further, described retainer ring is fixed on described combustion gas cavity by 12 screws.
Further, it is provided with sealing ring between described retainer ring and combustion gas cavity.
Further, described release assembly also include locating ring, described locating ring be arranged on combustion gas inside cavity and with release
Put cylinder to install with one heart, locating ring inwall and the interior walls be smooth transition of combustion gas cavity, and locating ring is provided with away from the one end discharging cylinder
Spacing closing in.
Further, described stay cord is drawn into Kev by carbon fiber.
Further, the material of described pressurize pin is H62Y2 copper rod.
Further, described gas generator adds sealing ring by screw thread and is connected with combustion gas cavity.
Further, described release cylinder adds sealing ring by screw thread and is connected with combustion gas cavity.
Beneficial effect: high speed pay-out overload that the high speed of the present invention, low overload relieving mechanism are the lowest, it is to avoid damage unit device
Part；Novel structure, reusable, reduce manufacturing cost, be effectively shortened the production cycle.
Accompanying drawing explanation
Accompanying drawing 1 is the structure chart of the release cylinder of prior art；
Accompanying drawing 2 is high speed, the structure chart of low overload relieving mechanism.
Detailed description of the invention
Below in conjunction with the accompanying drawings the present invention is further described.
A kind of high speed as shown in Figure 2, low overload relieving mechanism, including gas storage assembly, release assembly 2 and braking group
Part 3, described gas storage assembly includes that gas generator 11 and combustion gas cavity 12, described gas generator 11 add sealing by screw thread
Circle is connected on combustion gas cavity 12 and the most ventable；Described release assembly 2 includes being connected in releasing on combustion gas cavity 12
Put cylinder 21 and the release push pedal 22 that is slidably matched of cylinder 21 and be fixed on the pressurize pin 23 on release cylinder 21 barrel, described in release
Put cylinder 21 to add sealing ring by screw thread and be connected with combustion gas cavity 12 and communicate inside both.Described pressurize pin 23 not only can voltage stabilizing but also
Can fix and be released component, it is preferable that its material is H62Y2 copper rod.
Described brake assemblies 3 includes the bolt stay cord 31 in described push pedal 22 with combustion gas cavity 12 inwall, in described push pedal 22
Being provided with draw ring 32, the inwall of described combustion gas cavity 12 is provided with retainer ring 33, the two ends of described stay cord 31 are separately fixed at
On described draw ring 32 and retainer ring 33.Described retainer ring 33 is fixed on described combustion gas cavity 12 by 12 screws, and fixing
It is provided with sealing ring between ring 33 and combustion gas cavity 12.As preferably, described stay cord 31 is drawn into Kev by carbon fiber.
Described release assembly 2 also include locating ring 24, described locating ring 24 be arranged on combustion gas cavity 12 internal and with release
Cylinder 21 is installed with one heart, locating ring 24 inwall and the interior walls be smooth transition of combustion gas cavity 12, and locating ring 24 is away from release cylinder 21
One end is provided with spacing closing in.
Compared to prior art, the invention have the advantages that
1, the gas generator 11 method aerogenesis by grate firing, is unlikely to be rapidly reached release pressure, during release also
Energy QI invigorating, keeps release pressure；
2, strengthen the volume of combustion gas cavity 12, also can play pressure maintaining effect；
3, removing the step of release cylinder 21, hold push pedal 22 by stay cord 31, stay cord 31 is fixed on combustion gas cavity 12, with
Time release cylinder 21 in dynamic seal ring is installed, with against shock, thus greatly reduce release overload, in order to avoid damage components and parts.
