First installation concave part 110 and the first fastener 120 are arranged on the upper of base unit 100
Portion, and, described first installation concave part 110 and the first fastener 120 section of having are poor.
Specifically, with reference to Fig. 4 (a), (b), base unit 100 includes rectangular substrate
101, portion is provided with the first installation concave part 110 and the first fastener 120 on the substrate 101,
Described first installs concave part has two above installation grooves of row formed side by side, and described first
Fastener is arranged on the described first two ends row installing concave part, and described first installs groove
Between portion and the first fastener, the section of having differs from 102.
First installation concave part 110 includes that formed side by side two arrange above installation groove 111,
Described installation groove 111 has the curvature identical with the external diameter of fuel assembly 10 and is bent to form,
One or more fuel assembly 10 is installed in each installation groove 111.The present embodiment shows
Go out is to install the situation of two fuel assemblies 10 of receiving in groove 111 at one.
Each groove 111 of installing connects with the horizontal plane 112 of one fixed width, it is preferable that horizontal plane
The two ends of 112 are provided with reference mark 112a such that it is able to illustrate and be arranged on installation groove 111
The reference position of fuel assembly.
Suitably determine furthermore it is possible to maintain between fuel assembly 10 in the range of appropriate intervals
Determine the width of horizontal plane 112.
First fastener 120 is symmetrically arranged on the two ends of the first installation concave part 110
Row, and exceed certain altitude h than the first installation concave part 110 and highlight and formed, thus anti-
Only it is arranged on and the fuel assembly of groove 111 is installed to the outside landing of base unit 100.
It addition, the bottom surfaces of substrate 101 farther includes the jog 130 of prominent formation, institute
State jog 130 and be sticked in pallet 400 (with reference to Fig. 3), thus guide base unit 100 to exist
Location on pallet 400 and installation, and limit moving horizontally of base unit 100, thus
Can prevent packing crates from falling from pallet 400 in handling process.
Jog 130 can be to have certain thickness piece, and can be appropriately configured at substrate
The bottom surfaces of 101, this suitably can be determined by the installed surface structure of pallet 400.
Then, with reference to Fig. 5, temporary location 200 includes having the body structure of lower open
First main part 201, and, the bottom of the first main part 201 is provided with the first fixed groove
Portion 210, it is recessed that described first fixed groove portion 210 has the first installation corresponding to base unit
Each fixed groove 211 installing groove 111 (with reference to Fig. 4) and be bent to form in groove portion 110；

Two become arrange above installation groove 221；Second fastener 230, it is arranged on the second installation
The two ends row of concave part 220, and highlight formation and concave part 220 is installed higher than second.
Second installation concave part 220 and second fastener on the top of composition temporary location 200
The structure of 230 is practically identical with the superstructure of base unit, therefore, omits saying of repetition
Bright.
As illustrated in (b) of Fig. 5, temporary location 200 bottom is provided with the first fixed groove
Portion 210, described first fixed groove portion 210 has installs concave part 110 corresponding to first
Each fixed groove 211 installing groove and be bent to form, each fixed groove 211 and first is installed
The groove 111 of installing of concave part 110 is respectively provided with the radius of curvature identical with fuel assembly.
Specifically, with reference to Fig. 6 (a), fixed groove 211 has the stationary plane 211a of semi-circular cylindrical
The taper surface 211b extended with certain inclination with the opening at stationary plane 211a.
Stationary plane 211a has radius of curvature r roughly the same with fuel assembly 10, stationary plane
The arc chord angle θ 2 of 211a is than the arc chord angle θ 1 big (θ 1 ＜ θ 2) installing groove 221, it is preferable that
Its maximum is less than 180 °.
There is the fixed groove 211 of this stationary plane 211a and taper surface 211b for greatest extent
The structure of cladding fuel assembly 10, owing to having the taper surface of the inclination of expansion, therefore, holds
Easily assemble with fuel assembly 10.
As (b) of Fig. 6 illustrates, fixed groove 211 is provided with vertically prominent formation
Dividing plate 212, be equivalent to one row fixed groove 211 in receiving plural fuel
During assembly, two fuel assemblies are spatially separated.
Referring again to Fig. 5, the first main part 201 is provided around introducing the multiple clamping parts formed
201a, thus can improve operator's during opening or cover temporary location 200
Ease-to-operate.
It addition, the flanking central of the first main part 201 is provided with can paste impact display
Assembly mouth 201b.
Then, with reference to Fig. 7 and Fig. 8, upper unit 300 includes the casing with lower open
Second main part 301 of structure, the bottom of the second main part 301 is provided with the second fixed groove
Portion 310, described second fixed groove portion 310 has corresponding to the second installation concave part 220
The fixed groove 311 being bent to form, and form insertion combination with temporary location 200 top.
The structure in the second fixed groove portion 310 of composition upper unit 300 bottom and temporary location
The first fixed groove portion 210 of 200 is practically identical, and therefore, the repetitive description thereof will be omitted.
The upper surface of the second main part 301 is arranged flatly, to be capable of two grades of loadings, and
And be provided around multiple clamping part 301a, thus opening or covering upper unit 300
During can improve the ease-to-operate of operator.
It addition, injured during in order to prevent operator from operating, it is preferable that by the second main part
The corner of 301 is processed into fillet or chamfering.
It is provided with angle on the position of frenulum when the corner of the second main part 301 is with trays
Plate 301b, and the belt cased by bale packing prevents the corner of upper unit impaired.
Present invention mentioned above is not limited to aforesaid embodiment and accompanying drawing.For the present invention
For those skilled in the art, permissible without departing from the range of the technological thought of the present invention
Carry out replacing, deform and changing being apparent from.
