Structure is drivingly connected the other end of the locking bar, to drive the locking bar in the intracavitary movement of the locking bar.
A kind of back door of garbage truck device provided by the utility model, under normal circumstances, back door are closed, and lock piece is located at limit
In slot, when needing to open back door, driving mechanism driving locking bar is moved upwards, and lock piece is moved up from limiting slot, when on locking bar
When end reaches the first strip-shaped hole upper end, since back door upper end and compartment top are hinged, driving mechanism then will push back door along hinged
Locate Unscrew, when needing closing back door, due to the angular relationship at back door, starting hour locking lever will not be moved, and driving mechanism is made
It with can first tense back door, is then moved downward in driving locking bar, lock piece is downwardly into limiting slot therewith, reaches car door certainly
The purpose of lock.The utility model has the advantages of simple structure, is self-possessed small and can lock door certainly.
The above description is merely an outline of the technical solution of the present invention, in order to better understand the skill of the utility model
Art means, and can be implemented in accordance with the contents of the specification, below on the preferred embodiment of the present invention and the accompanying drawings in detail
It describes in detail bright as after.Specific embodiment of the present utility model is shown in detail by following embodiment and its attached drawing.
Detailed description of the invention
Attached drawing described herein is used to provide a further understanding of the present invention, and is constituted part of this application,
The exemplary embodiment of the utility model and the description thereof are used to explain the utility model, does not constitute to the improper of the utility model
It limits.In the accompanying drawings:
Fig. 1 is the side structure schematic diagram of the utility model embodiment；
The structural schematic diagram at back door in the utility model embodiment of the position Fig. 2.
Specific embodiment
The principles of the present invention and feature are described below in conjunction with attached drawing, example is served only for explaining that this is practical
It is novel, it is not intended to limit the scope of the utility model.It is more specifically described by way of example in the following passage referring to attached drawing
The utility model.According to following explanation and claims, will be become apparent from feature the advantages of the utility model.It should be noted
It is that attached drawing is all made of very simplified form and using non-accurate ratio, only to facilitate, lucidly aid in illustrating this reality
With the purpose of new embodiment.
As depicted in figs. 1 and 2, the utility model provides a kind of back door of garbage truck device, including compartment 1, back door 2 and two
Group locking system 3,2 upper end of back door and 1 top of compartment are hinged, and two groups of locking systems 3 are symmetrically disposed on the compartment 1
Two sides, and every group of locking system 3 includes a driving mechanism and a locking bar 32, the back door 2 is formed with lock by the position of proximal edges
Rod cavity 21, the locking bar 32 are movably installed in the locking bar chamber 21, and the side wall at the back door 2 corresponds to the two of the locking bar chamber 21
End is respectively equipped with the first strip-shaped hole a and the second strip-shaped hole b, and the second strip-shaped hole b is located at 2 lower end of back door, and described the
One strip-shaped hole a is located between the top and bottom at the back door 2, and 1 side wall lower ends of compartment correspond to the back door 2 equipped with jam plate
11, one end of the locking bar 32 is equipped with the lock piece 321 through the second strip-shaped hole b, the corresponding locking of jam plate 11
The position of part 321 is formed with limiting slot 11a, and the driving mechanism is drivingly connected the other end of the locking bar 32, to drive
Locking bar 32 is stated to move in the locking bar chamber 21.
Preferably, the power output rod which can be for linear motion with one, the direction of motion of power output rod
Consistent with its length direction, the one end of one end of the power output rod with the locking bar far from the lock piece is hinged, and institute
It states one end height that power output rod is connect with the locking bar and is higher than its other end.
It is understood that the driving mechanism with above-mentioned technical characteristic includes but is not limited to cylinder, hydraulic cylinder, straight-line electric
Machine, rack-and-pinion group, these driving mechanisms are used equally for the locking bar in driving the utility model, and reach essentially identical technology
Effect.
Since one end height that power output rod is connect with the locking bar is higher than its other end, locked when power output rod pushes
When bar moves upwards and then releases lockup state, back door also will receive the power pushed out, and then make its opening.
Preferably, the distance between the lower end the first strip-shaped hole a and the lower end the second strip-shaped hole b and the locking bar 32
Equal length, in this way when lock piece and limiting slot cooperation locking back door when, locking bar upper end is also located just under the first strip-shaped hole
End, ensure that the stability of back door lockup state.
In the present embodiment, driving mechanism is preferably hydraulic cylinder 31, then power output rod is also just hydraulic lever 311；When
When the hydraulic cylinder rod 311 is recovered in the hydraulic cylinder 31, the lock piece 321 is located at the lower end of the second strip-shaped hole b
And it is located in the limiting slot 11a.
Under normal circumstances, back door is closed, and lock piece is located in limiting slot, when needing to open back door, driving mechanism driving
Locking bar moves upwards, and lock piece is moved up from limiting slot, when locking bar upper end reaches the first strip-shaped hole upper end, due to back door upper end
Hinged with compartment top, driving mechanism then will push back door along hinged place Unscrew, when needing closing back door, due to back door
Angular relationship, start hour locking lever will not move, driving mechanism function can first tense back door, then driving locking bar transport downwards
Dynamic, lock piece is downwardly into limiting slot therewith, achievees the purpose that car door is self-locking.The utility model has the advantages of simple structure, is self-possessed small
And it can lock door certainly.
The above, the only preferred embodiment of the utility model not make in any form the utility model
Limitation；The those of ordinary skill of all industry can be shown in by specification attached drawing and described above and swimmingly to implement this practical
It is novel；But all those skilled in the art are not departing within the scope of technical solutions of the utility model, using being taken off above
The technology contents shown and the equivalent variations of a little variation, modification and evolution made, are the equivalent embodiment of the utility model；
Meanwhile it the change of all substantial technological any equivalent variationss to the above embodiments according to the utility model, modifying and drilling
Become etc., within the protection scope for still falling within the technical solution of the utility model.
