Specific embodiment
Embodiment
As shown in Fig. 1-Fig. 7, a kind of spring cartridge type rear board locking device, it includes：Pivoted arm assembly（1）, positive stop
（2）, rotating shaft support plate（3）, rotating shaft（4）, pressure cylinder assembly（5）, adjusting nut（6）, pull bar（7）, connection fork（8）, bearing pin I（9）、
Lock hook seat（10）, pin shaft II（11）, latch hook（12）, locking seat assembly（13）, return spring（14）, spring hanging plate（15）, pivoted arm
Bearing（16）, spacing board support（17）, limiting plate（18）Split pin（B1）, nut（B2）, split pin（B3）, pivoted arm assembly（1）
With rotating shaft support plate（3）Connection, pressure cylinder assembly（5）By rotating shaft（4）It is connected to pivoted arm assembly（1）On, adjusting nut（6）Arrange
In pull bar（7）On, pull bar（7）One end pass through nut（B2）It is connected to connection fork（8）On, connection fork（8）By bearing pin I（9）
It is connected to locking seat assembly（13）On, latch hook（12）By pin shaft II（11）It is connected to lock hook seat（10）On, return spring（14）
Two ends and spring hanging plate（15）Connection；When the spring of pressure cylinder assembly is not subject to other larger external force to act on, retaining mechanism is with casing
Lifting and fall, rear board is normally opened and is closed；When vehicle is in abnormality, by external force thrust, push away
Dynamic rear board, make rear board push away Lee more than spring strut inner spring pretightning force when, rear board open.
Operation principle of the present utility model is as follows：
1st, by design requirement, all of parts are assembled, allow whole device assembly box body lifting, fall when, energy
It is normal to run.When casing falls, pivoted arm assembly（1）By positive stop（2）Effect so that retaining mechanism move forward,
The latch hook of retaining mechanism is driven to hook locking seat assembly simultaneously（13）Upper lock pin, locks rear board.And now pressure cylinder assembly（5）
The thrust born more than rear board after filling dregs in casing by interior initial tension of spring so that rear board is locked.
When the 2nd, rising casing by the powerlifting of elevating ram, pivoted arm assembly（1）Also rise therewith, by positive stop
（2）Hinder less and less, in return spring（14）In the presence of, drive retaining mechanism to be moved rearwards by, it is total that latch hook unclamps locking seat
Into（13）On lock pin, open rear board.
3rd, vehicle full load, when construction site pavement conditions difference is encountered in building site, tire is easily trapped into road surface, vehicle
There is different degrees of inclination in casing, it is impossible to lift, in case, dregs cannot be unloaded.Can only be by using slag in excavator unloader box
Soil, when excavator skims soil backward, the power born by rear board becomes what the thrust of dregs in casing increased plus excavator
Thrust, more than the pretightning force of pressure cylinder assembly inner spring, below rear board, latch hook unclamps lock to the power at this moment born on rear board
The only lock pin of seat assembly so that rear board is opened.Slag while car load is not subject to any loss, in the smooth unloader box of energy
Soil.
This utility model is not limited to above-mentioned preferred implementation, and anyone should be learnt in enlightenment of the present utility model
Under the structure change made, it is every have with this utility model it is same or like as technical scheme, belong to the present invention's
Protection domain.
