The tapered end that forms among this embodiment, it specifically uses use as follows:

Referring to Fig. 6, at first the tapered end among this embodiment 100 is arranged on the 3# locking bar 300 of freight container, the 10mm owing to stagger between the line of centers 101 of the straight pin 100 of tapered end 100 and the line of centers 203 of latch 200 makes it compare with common tapered end with holes, and the center takes over.It installs this tapered end on locking bar, also this tapered end can be installed, but particular case and deciding.

When opening chamber door, the first step: rotate 3# locking bar upper handle, make the upper raised teeth on the tapered end contact (as shown in Figure 7) with lock.

Since adopt that the utility model provides tapered end, compare with common tapered end with holes, after the tapered end off centering, 10mm has been lacked to the distance at locking bar center in its long double wedge summit.

Simultaneously, in the reference position that the long double wedge of tapered end contacts with lock, the angle between handle and the door-plate is bigger 2 times than original, has promptly increased the stroke of tapered end idle running, has reduced and has finished the required power of next step action.

Moreover the contact line length of long double wedge of tapered end and lock has reduced about 14.8mm, has alleviated the wearing and tearing between tapered end and the lock.

Second step: rotate on the 3# locking bar handle to the about 90 ° of positions of doorframe, make of short duration contact the bottom long angle of tapered end and the lock with less power, door-plate is strutted about 15mm (as shown in Figure 8).

Because the tapered end off centering makes the long double wedge vertex distance of tapered end locking bar center shorten 10mm, thereby has reduced resisting moment, according to lever principle, can be more laborsaving during turning handle than adopting common tapered end.

The 3rd step: the handle that continue to promote on the 3# locking bar goes to and the about 110 ° of positions of doorframe, makes the tapered end intermediate projections piece that opens ice contact (as shown in Figure 9) with the lock top.

The tapered end intermediate projections opens ice and can make piece at this moment door-plate obtain bigger unlatching with less power in this step.

The 4th step: the handle that continues to promote on the 3# locking bar turns to and the about 175 ° of positions of doorframe (as shown in figure 10).

Utilize in this step tapered end open ice piece when contacting with the lock top resistance arm less, according to lever principle, required drive is less.Thereby will open the about 40mm of door-plate with less power.

The 5th step: rotate 4# locking bar upper handle to the about 170 ° of positions of doorframe.

Only need between 4# lever lock head and the lock in this step contact in about 90 ° to 170 ° scopes, this moment is same only to be needed less power can promote the 4# locking bar to rotate.

This step can be opened the about 80mm of door-plate, then just can be easily with the right Men Lakai of freight container, rotate the 1# locking bar again and the 2# locking bar is opened left-hand door, just finished the whole action of opening the door.

And the common mode of opening the door is after relying on the long double wedge of 3# locking bar tapered end to strut the about 20mm of door-plate, by the long double wedge of 4# locking bar tapered end door-plate to be strutted about 40mm, by the piece that opens ice in the middle of the tapered end door-plate is strutted about 80mm again, thereby plays open door effect.

The long double wedge performance of main dependence tapered end leverage struts door-plate in the common process of opening the door, and needs very big pulling force ability execution.And the novel fast-open type tapered end that adopts the utility model to provide, the long double wedge of its tapered end summit is less to locking bar centre distance, only needs less power in the process of opening the door.Therefore novel fast-open type tapered end can allow the operator feel more laborsaving with respect to common tapered end.

By relevant test as can be known:

Adopting the common tapered end required maximum torque of opening the door is 50Nm;

Adopting the new fast-open type tapered end required maximum torque of opening the door is 30Nm.

Thus, as seen adopt new fast-open type tapered end will make the operator laborsaving 40%, make the labor intensive of opening the freight container chamber door reduce greatly.Relevant operating personal need not the strong male sex, and general women is easily to open chamber door.

As second purpose of the present utility model, the utility model also provides a kind of locking bar, and the two ends of this locking bar are provided with above-mentioned fast open form anti-theft lock end.
