Specific embodiment
In order that those skilled in the art more fully understand technical scheme, below in conjunction with specific embodiment pair
Technical scheme is done and is further discussed in detail.
As shown in Figure 3 and Figure 4, retaining mechanism before container provided in an embodiment of the present invention, including set lever 1, described lock
Tight handle 1 is hinged with the set lever base 7 being fixed on container front frame assembly a by handle pin 6, and passes through shackle bearing pin
3 is hinged with locking shackle 2, and specifically, described handle pin 6 can be pressed with described set lever base 7 and be connected, described base lock
The structure of tight handle base 7 is as shown in figure 8, more described set lever 1 is movably articulated in described handle pin；Described locking
Shackle 2 also can be pressed with described shackle bearing pin 3 and be connected, then will be hinged with described locking shackle 2 for described set lever 1；Described
Locking shackle 2 and container header board latch hook 9 clasp joint being connected described container front frame assembly a and cargo box sideboard assembly b；Described locking handss
It is provided with mounting bracket 8 on spring inside handle 1, described spring is connected with spring 5 between mounting bracket 8 and described shackle bearing pin 3.
As shown in Figure 5 and Figure 6, when needing locking, described set lever 1 revolves upwards around handle pin 6 and shackle bearing pin 3
Transhipment is dynamic, realizes by the change free state, most compressed state to locking state, when reaching locking state
When, shackle is connected center o1 with container header board latch hook, handle pin center o2, shackle bearing pin center o3 are in eccentric position for locking
Put, i.e. 3 points of distributions triangular in shape, spring is compressed, set lever 1 relies on self gravitation, the elastic force of spring 5 and locking shackle 2
Active force reach stress balance, keep preferably locking state, locking during container vibration can be prevented to lose efficacy；In addition, with existing
Technology is compared, and this retaining mechanism avoids is locked using frictional force, is conducive to improving its service life.
In this enforcement power specific implementation process, the two ends of described spring 5 can be separately fixed at described spring upper bracket 8 He
On described shackle bearing pin 3, but during described set lever 1 rotates up motion, because described spring 5 is fixed on institute
State the change of shackle bearing pin 3 one end position, the change in elastic force direction can be caused, lead to bearing pin stress to be partial to, for avoiding this to ask
Topic, also includes mounting bracket 4 under spring in retaining mechanism before described container, under described spring, mounting bracket 4 is that arc is hardened
Structure, is overlapped on described shackle bearing pin 3, described spring 5 is connected on described spring and installs under mounting bracket 8 and described spring
On the vertical center line of support 4, manipulate when, described spring lower carriage 4 can along the center rotating of described shackle bearing pin 3,
Realize spring force all the time on mounting bracket and shackle bearing pin center line connecting direction on spring, prevent bearing pin stress to be partial to.
Reinforcement raised 41 can be provided with mounting bracket 4 under described spring, as shown in figure 9, to ensure the intensity of support.
In addition, as shown in fig. 7, being the structural representation of set lever provided in an embodiment of the present invention, described set lever 1
Including handle body 11 and be respectively perpendicular the side plate 12 being connected to described handle body 11 both sides, described spring 5 is located at two groups of institutes
State the inside of side plate 12, and connect parallel to described side plate 12, this structure, spring can be avoided to interfere with peripheral parts,
Impact locking operation, and described spring 5 is arranged parallel to described side plate 2, the parts such as bearing pin, side plate can be avoided to be partial to
Power, reduces to structural damage.
Lightening hole 13 can be offered on described side plate 12, make the motion of set lever 1 more flexible.
In operation, after described locking shackle 2 motion, its top can be abutted with described container front frame assembly a, thus
Produce friction, for avoiding wearing and tearing, between described locking shackle 2 and described container front frame assembly a, reinforcing plate 10 can be provided with.
Construction, feature and the action effect of the present invention, above institute are described in detail above according to the embodiment shown in schema
State only presently preferred embodiments of the present invention, but the present invention is not to limit practical range, every structure according to the present invention shown in drawing
Want made change, or be revised as the Equivalent embodiments of equivalent variations, when still covered with diagram without departing from description spiritual,
All should be in protection scope of the present invention.
