Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Location drawing when Fig. 2 is the utility model works limit.
Specific implementation mode
The following describes the utility model in further detail with reference to the accompanying drawings, to enable those skilled in the art with reference to explanation
Book word can be implemented according to this.
It should be appreciated that such as " having ", "comprising" and " comprising " term used herein do not allot one or more
The presence or addition of a other elements or combinations thereof.
The utility model provides a kind of container back door lever opening device, including：Hold-down support 1, by welding or
It is bolted on subframe or vehicle frame；Horizontal lever 3, stage casing are bolted to by shaft 4 and are welded in container side plate
On shaft seating 5, the tail end of the horizontal lever 3 is welded in by axis pin 6 and nut connecting hinge plate on the back door of container, described
The back door of container is locked by locking mechanism 7 and container side plate, prevents from spilling material, also can discharging initial stage effective protection back door not by
Material impact, to achieve the purpose that protection mechanism, as lifting angle increases, back door aperture becomes larger, and meets discharging in this way
Smoothness in turn avoids back door premature breakdown due to material impact；Chain 2, one end pass through adjusting bolt and the fixed branch
Seat 1 is hinged, and the other end is connect by axis pin with the front end of the horizontal lever 3, for balancing container in lifting, overcomes back door certainly
The torque that weight is formed with horizontal lever.
With packing case lifting, container ontology tail end declines, and under the effect of horizontal lever 3, back door keeps overhead positions substantially, unloads
Material space is increasing with lifting.Back door uses hinged and combines back door retaining mechanism 7 with horizontal lever 3, can be at discharging initial stage
Effective protection back door is not by material impact, and as lifting angle increases, back door aperture becomes larger, and it is smooth to meet discharging in this way
Property, in turn avoid back door premature breakdown due to material impact.
The utility model forms connecting rod by horizontal lever 3, shaft 4, shaft seating 5, chain 2, with container rollback point itself
Mechanism realizes that back door is opened by packing case lifting.In packing case lifting, by welding or being bolted in subframe or vehicle frame
On hold-down support 1 pull chain 2, chain 2 to pull horizontal lever 3, horizontal lever 3 connected by shaft 4 and container relative rotation
Container back door on horizontal lever 3 is rotated relative to container simultaneously with horizontal lever, to open container back door.When container falls,
Container back door rotates under effect of weight relative to container together with horizontal lever 3, to close truck compartment rear door.
When cargo has knocked container back door in dumping process, then container back door can by axis pin 6 with respect to horizontal lever 3 into
Row rotation, leads to the problem of the impact at container back door to effectively prevent cargo, would not when cargo is in dumping process
Container back door is knocked, container back door is just returned to initial position under effect of weight.As shown in Fig. 2, for the limit of packing case lifting
Position, chain component 2 and horizontal lever 3, should avoid collinearly, no it will cause link mechanism damages at this time.As shown in the figure, back door
Specifically become larger with container tail end, and non-articulated opener, back door decline with packing case lifting.By this device to realize protection after
Door is not hit, and eliminates clamping stagnation of the back door to discharging.
The back door of another embodiment, the container is locked by locking mechanism and container side plate, the locking mechanism fastening
Reliably, anti-impact force is strong, is unlikely to deform.
Another embodiment, the locking mechanism include：Multiple pin holes are welded on the container side plate；Shank, weldering
It is connected on the back door of the container, the position of the shank and quantity are adapted with the pin hole, and the shank is cavity body, institute
State and be provided with movable tenon and elastomer in cavity body, it is described activity tenon have from the cavity body stretch out the shank tenon and
It is placed in the limiting section of the cavity body, the free end of the limiting section is abutted with the elastomer phase, the limiting section and described
Elastomeric seal is in the cavity body；Connecting rod, one end are connect with described movable tenon one end, and the other end connects with hydraulic cylinder
It connects, the tenon connects the hydraulic cylinder for driving the tenon to lock and open by connecting rod.It is logical using hydraulic cylinder
It crosses the flexible of connecting rod control tenon and realizes locking and open back door, this locking and opening structure are solid and reliable, and fastening is durable,
And it is simple in structure at low cost, easy for installation.
Another embodiment, the activity tenon is "T"-shaped piece.
The limiting section of another embodiment, the activity tenon is placed between two elastomers, and described two elastomer phases are to setting
It sets, the limiting section is isosceles triangle plate, and the fixed-focus of the limiting section and base angle are fillet.This is simple in structure, and nothing adds
Batch production can be achieved by essence casting or forging in work dead angle.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
