Fig. 5 please be now go to, optionally, the maximal axial extension H of protrusion 163 to first end 161 is less than end plate 151 and arrives
The maximum distance D of end wall 110, so that the protection by block piece 150 in the locked condition of flange bolt 160, avoids delivering
It is scraped in journey and bumps against other articles, damaged.
It is also preferable that optionally, the maximal axial extension G of protrusion 163 to the second end 162 is greater than end plate 151 and arrives
The minimum range F of end wall 110.In other words, as shown in fig. 6, flange bolt 160 unscrew outward outer surface to ring flange with
In the state of the inner surface fitting of block piece 150, the second end 162 of flange bolt 160 without departing from end wall column 111, with
This can prevent flange bolt 160 from losing.
As shown in Figure 7 and Figure 8, end wall 110 can be enough to ensure that flange bolt to inclination on the outside of cabinet, inclined angle
160 completely disengage side wall column 121, and flange bolt 160 is tilted in block piece 150 due to gravity at this time, but in flange spiral shell
Bolt 160 it is upper and lower it is inclined during, block piece 150 can guarantee that flange bolt 160 does not depart from end wall column 111, effectively prevent
The loss of flange bolt 160.
As shown in Figure 5 and Figure 6, nut 170 can further comprise along its axially projecting boss 171, and boss 171 can prolong
It extends into the second opening 122 of side wall column 121 with positioning, guarantees accurate positioning when welded nut 170.

Although the block piece 150 shown has U-shaped structure, the shape of block piece 150 is also possible to other shapes, such as
Two open ends of block piece 150 can be closed to form a box-like, or use cylindrical part or oval cylindrical member etc..
As shown in fig. 6, in the feelings for guaranteeing that the non-bulging pallet box outside dimension of block piece 150 and flange bolt 160 are not lost
Under condition, the minimum range F of the depth F of 150 indent of block piece, i.e. end plate 151 to end wall 110 should be big as far as possible, this can be convenient method
Tightening for blue bolt 160 is operated with release.Because two upper corners of each end wall 110 respectively have a sleeve locking apparatus, when two
When flange bolt 160 is not tightened or unclamped simultaneously, the ring flange of flange bolt 160 can interfere with the inner surface of block piece 150, make
End wall 110 generates some flexible deformations, increases resistance when flange bolt 160 is tightened or unclamped, increases 150 indent of block piece
Depth F can be such that the flexible deformation of end wall 110 reduces, to reduce resistance when flange bolt 160 is tightened or unclamped.
Fig. 7 and Fig. 8 are returned to, when organizing vertical pallet box, two end walls 110 are first installed on to the end on chassis 130 relative to one another
Bian Shang, by end wall 110 to inclination on the outside of cabinet (limitation for 130 end edge of angle suspension chassis that end wall 110 is inclined outwardly, herein not
Show), then two side walls 120 are installed on relative to one another on the side on chassis 130, then the inclined end wall 110 of righting;
The process of righting end wall 110, while the bottom end of flange bolt 160 (the second end 162) is directed at nut 170, take interior hexagonal
Spanner screws the operation portion 164 of interior hexagon flange bolt 160, until the bottom surface of ring flange and the outer surface of end wall column 111 are close
The locking of end wall 110 and side wall 120 is completed in fitting.
It after pallet box completes delivery cargo, needs to be dismantled delivery, saves carrying space, save transportation cost.It is desirable
Interior hexagon flange bolt 160 is unscrewed outward with allen wrench, until the inner surface of the upper surface of ring flange and block piece 150 pastes
It closes, flange bolt 160 is not yet completely disengaged with nut 170 at this time.Because end wall 110 can be tilted on the outside of cabinet, so can be after
Continuous to unscrew flange bolt 160, flange bolt 160 applies outside thrust to block piece 150, block piece 150 drive end wall 110 to
Outer incline.
When flange bolt 160 and nut 170 completely disengage, end wall 110 is no longer fettered by locking device, can manually by
End wall 110, which continues to be inclined outwardly to the bottom end of flange bolt 160 and side wall column 121, completely disengages that (end wall 110 is inclined outwardly
The limitation of 130 end edge of angle suspension chassis, does not show herein).Because of the inner surface of block piece 150 and the appearance of end wall column 111
The distance F in face is less than upper surface and 160 lower end surface distance G of flange bolt (the i.e. protrusion 163 to the second end of ring flange
162 maximal axial extension G), so ensure that flange bolt 160 is not separated with end wall column 111.The diameter C of ring flange is big
In the length A or width B of end plate opening 152, ring flange cannot guarantee that flange bolt 160 cannot be detached from blocking by long round mouth
Part 150 effectively prevent the loss of flange bolt 160.
Above-mentioned flange bolt 160 tighten or the mode of unclamping refers to that two flange bolts 160 on end wall 110 are alternately tightened
Or unclamp, in order to easy to operate, improve efficiency, flange bolt 160 can also once be tightened or be unclamped in place, at this time flange spiral shell
The upper surface of the ring flange of bolt 160, which can generate pressure with the inner surface of block piece 150, makes 110 flexible deformation of end wall, but not shadow
It rings and completes tightening or unclamping for flange bolt 160.
