[0038] In the embodiments shown in the drawings, the indications of directions (such as up, down, left, right, front and back) used to explain the structure and movement of various elements of the utility model are not absolute but relative. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0039] The utility model provides a loading box, which can be used to accommodate components such as a fuel injection nozzle 4, so as to carry out integral packaging and transportation of a plurality of independent components.

[0040] The following description will be made by taking the loading box loading the fuel injection nozzle 4 as an example.

[0041] Figure 1 The exploded view of the loading box is shown. Figure 2 The internal structure of the box 1 is shown in a cross-sectional view. Figure 3 A structural diagram of the supporting member 31 is shown.

[0042] Combination Figure 1 and Figure 2 The loading box includes a box body 1, a cover body 2 and a supporting member 31. The height of the supporting member 31 in the box body 1 is adjusted by cooperating with a plurality of clamping parts 32 on the supporting member 31 and an upper supporting surface 121 and a lower supporting surface 131 in the box body 1, so as to adapt to fuel injectors 4 of different lengths, thereby improving the versatility of the loading box and reducing the number of specifications of the loading box.

[0043] The box body 1 has an accommodating space 11 with an opening facing upward, so that a worker can conveniently put the supporting member 31 and the fuel injection nozzle 4 on the supporting member 31 into or take out the accommodating space 11 through the opening.

[0044] The cross-sectional shape of the box body 1 can be square, and the corresponding supporting member 31 can be square. The cross-sectional shape of the box body 1 can be hexagonal, circular or other shapes.

[0045] Specifically, the box body 1 includes a bottom wall and a side wall erected on the bottom wall. In order to improve the strength of the box body 1, reinforcing ribs can be provided on the outside of the side wall, and can actually be provided on the outer peripheral wall of the side wall. Reinforcing ribs can also be provided on the top of the bottom wall. The specific arrangement depends on actual needs.

[0046] The inner side wall of the box body 1 includes an upper support assembly 12 and a lower support assembly 13 which are arranged in sequence along the vertical direction, and the upper support assembly 12 is located above the lower support assembly 13 .

[0047] The upper support assembly 12 is formed with at least upper support surfaces 121 arranged on opposite sides of the box body 1. The upper support surfaces 121 extend in the horizontal direction. In this embodiment, the upper support surfaces 121 are arranged on all four sides of the box body 1. In other embodiments, the upper support surfaces 121 can be arranged only on two opposite sides.

[0048] Specifically, the upper support assembly 12 includes a plurality of support blocks 122 arranged at intervals in the horizontal direction, and the tops of the plurality of support blocks 122 constitute the upper support surface 121. The plurality of support blocks 122 on opposite sides of the box body 1 are arranged in a staggered manner. The staggered arrangement means that the gap between two adjacent support blocks 122 on one side corresponds to the support block 122 on the other side.

[0049] The difference between the number of the supporting blocks 122 on two opposite sides of the inner wall of the box body 1 is one.

[0050] Specifically in this embodiment, the first side, the second side, the third side and the fourth side of the inner wall of the box body 1 are sequentially arranged, the first side is provided with four support blocks 122, the third side opposite to the first side is provided with five support blocks 122, the second side is provided with three support blocks 122, and the fourth side opposite to the second side is provided with two support blocks 122. And the space between two adjacent support blocks 122 on the same side corresponds to the support block 122 on the other side.

[0051] In other embodiments, support blocks 122 may be provided only on the first side and the third side of the box body 1, or only on the second side and the fourth side. The specific number of support blocks 122 on each side may be provided according to actual needs, and the support blocks 122 on opposite sides are staggered, and the space between two adjacent support blocks 122 on the same side corresponds to the support block 122 on the other side.

[0052] Specifically, the support block 122 is in a block structure. The top of the block-shaped support block 122 has an upward plane, and the support block 122 has a certain support area, which improves the support stability of the clamping portion 32 of the supporting member 31. Preferably, the size of the support block 122 gradually decreases from top to bottom, and the spacing between two adjacent support blocks 122 gradually increases from top to bottom. While ensuring the support strength of the support block 122 and the support area of ​​the upper support surface 121 for the supporting member 31, it can also reduce production materials and save costs. In this embodiment, the support block 122 is in the shape of a chamfered pyramid. The support block 122 can also be an inverted triangular block, a semicircular block, etc.

[0053] The support block 122 is preferably tilted outward from top to bottom. The support block 122 extends obliquely downward toward the side of the accommodating space 11 of the box body 1, and the side faces obliquely downward. Here, the inside refers to the direction toward the internal space of the box body, and the outside refers to the direction toward the outside of the box body. The support block 122 adopts the above-mentioned design of tilting outward from top to bottom, so that its inner side surface can form an inclined guide surface to guide the cooperation between the supporting member 31 and the support block 122.

[0054] The support block may be in a shape that does not decrease in size from top to bottom, such as a rectangle.

[0055] The support block 122 serves as a structure for limiting the supporting member 31 , and may also be a plate-shaped structure extending inwardly from the inner side of the box body 1 .

[0056] The lower support assembly 13 is formed with at least lower support surfaces 131 arranged on opposite sides of the box body 1. The upper support surface 121 and the lower support surface 131 are arranged vertically spaced apart. The upper support surface 121 and the lower support surface 131 are both facing upward.

[0057] Specifically, the lower support assembly 13 includes at least two supporting ridges 132 arranged on two opposite inner walls of the box body 1, each supporting ridge 132 continuously extends horizontally along the inner wall of the box body 1, and the top surface of each supporting ridge 132 constitutes the lower supporting surface 131. And each supporting ridge 132 is continuous in the horizontal direction.

[0058] The supporting ridge 132 is protruding relative to the inner wall of the box body 1, and the lower supporting surface 131 extends continuously and uninterruptedly in the horizontal direction.

[0059] In this embodiment, each supporting rib 132 extends downward to the bottom of the box body 1. Specifically, it extends to the inner bottom surface of the box body 1, further improving the strength of the box body 1 and the supporting rib 132.

[0060] In other embodiments, the supporting rib 132 may also be a horizontally continuously extending, uninterrupted strip-shaped protrusion structure.

[0061] The supporting rib 132 can be formed by pressing the side wall of the box body 1 inwardly. The supporting rib 132 can also be directly formed integrally with the box body 1. The supporting rib 132 can also be connected to the inner side wall of the box body 1 by welding, gluing, etc.

[0062] In this embodiment, the top of the lower support assembly 13 is connected to the bottom of the lower support assembly 13 , which specifically refers to the support block 122 extending downward to the top surface of the support edge 132 of the lower support assembly 13 .

[0063] In some other embodiments, the upper support assembly 12 and the lower support assembly 13 may be arranged at intervals. The height of the upper support surface 121 and the lower support surface 131 relative to the box body 1 and the height difference between them are mainly set according to the length of each type of fuel injector 4 to be adapted.

[0064] In some variations, the lower support assembly 13 may also include a plurality of protrusions arranged at intervals. The protrusions are arranged in a vertically staggered manner with the support blocks 122, or a protrusion is arranged below any two adjacent support blocks 122. The protrusions may be in the shape of strips or prisms.

[0065] Specifically, a support rib 132 is provided on one side of the inner wall of the box body 1 where the support block 122 is provided. In this embodiment, the first side, the second side, the third side and the fourth side of the inner wall of the box body 1 are all provided with support ribs 132 below the support block 122.

[0066] The cover 2 is disposed on the top of the box body 1 and covers the top opening of the accommodating space 11. The shape of the cover 2 is adapted to the shape of the top opening of the box body 1. The cover 2 can be directly placed on the top opening of the box body 1, or fixed to the box body 1 by a structure such as a snap connection or a lock.

[0067] The supporting member 31 is disposed in the accommodating space 11. The supporting member 31 is provided with a plurality of receiving portions 313 for receiving components. Figure 6 The housing portion 313 of the present embodiment can house the oil injection nozzle 44 .

[0068] At least two opposite sides of the supporting member 31 are provided with a plurality of inwardly recessed notches 33, the plurality of notches 33 are arranged at intervals, and the portion between any two adjacent notches 33 constitutes the clamping portion 32. That is, the notches 33 and the clamping portion 32 arranged on the same side of the supporting member 31 are arranged alternately in sequence.

[0069] The notches 33 arranged on two opposite sides are arranged alternately, and the clamping portions 32 arranged on two opposite sides are arranged alternately.

[0070] The notches 33 are not located at the ends of each side, and the portion between the notches 33 close to the ends of each side of the supporting member 31 and the ends of the supporting member 31 constitutes the abutting portion 34 .

[0071] The bottom surfaces of the multiple clamping parts 32 can abut against the multiple support blocks 122, so that the supporting member 31 is located on the upper support surface 121. Alternatively, the bottom surfaces of the multiple clamping parts 32 can abut against the lower support surface 131, and the multiple support blocks 122 are clamped in the multiple recesses 33, so that the supporting member 31 is located on the lower support surface 131.

[0072] When the plurality of notches 33 of the supporting member 31 cooperate with the supporting block 122 , the supporting member 31 moves downward along the guide surface on the inner side of the supporting block 122 .

[0073] The difference between the numbers of the notches on two opposite sides of the supporting member 31 is one.

[0074] Specifically in this embodiment, the first side, the second side, the third side and the fourth side of the supporting member 31 are sequentially arranged, the first side is provided with five notches 33 and four clamping parts 32, the third side opposite to the first side is provided with four notches 33 and three clamping parts 32, the second side is provided with two notches 33 and one clamping part 32, and the fourth side opposite to the second side is provided with three notches 33 and two clamping parts 32. And the space between adjacent notches 33 on the same side corresponds to the notch 33 on the other side.

[0075] In other embodiments, the notches 33 may be provided only on the first side and the third side of the supporting member 31, in which case the first side and the third side of the box body 1 are provided with the support block 122; the notches 33 may also be provided only on the second side and the fourth side, in which case the second side and the fourth side of the box body 1 are provided with the support block 122. The specific number of the notches 33 and the clamping portion 32 on each side may be provided according to actual needs, and the notches 33 on the opposite sides are staggered, and the space between the two adjacent notches 33 on the same side corresponds to the notch 33 on the other side.

[0076] In this embodiment, recesses 33 are provided on all sides of the supporting member 31, and upper supporting assemblies 12 and lower supporting assemblies 13 are provided on all sides of the box body 1, so as to improve the supporting strength of the upper supporting assemblies 12 and lower supporting assemblies 13 on the box body 1 to the supporting member 31, thereby increasing the supporting stability of the supporting member 31 and reducing the deformation of the supporting member 31.

[0077] When the supporting member 31 is placed in the box body 1 , it can be placed on the upper supporting surface 121 or on the lower supporting surface 131 , depending on actual needs.

[0078] Specifically, Figures 5 to 7 In the embodiment shown, the multiple clamping parts 32 on the supporting member 31 correspond to the multiple supporting blocks 122 on the box body 1 one by one. In addition, the clamping parts 32 on the opposite sides of the supporting member 31 are arranged in a staggered manner, and the supporting blocks 122 on the opposite sides of the box body 1 are arranged in a staggered manner, so that after the supporting member 31 is horizontally rotated 180°, as shown in FIG. Figures 8 to 10 In the embodiment shown, the clamping portion 32 on the supporting member 31 can be inserted downwardly into the gap between two adjacent support blocks 122 one by one and placed on the lower support surface 131 of the lower support assembly 13, and the support block 122 is located in the recess 33, so that the clamping portion 32 and the support block 122 are interlocked. The clamping portion 32 in this embodiment is placed on the support edge 132.

[0079] In this embodiment, when the supporting member 31 is placed on the upper supporting surface 121, the first side of the supporting member 31 corresponds to the first side of the box body 1, and the four clamping parts 32 on the first side of the supporting member 31 are placed one-to-one on the four support blocks 122 on the first side of the box body 1. A clamping part 32 on the second side of the supporting member 31 and two abutting parts 34 at both ends of the clamping part 32 are placed on the three support blocks 122 on the second side of the box body 1 respectively. The three clamping parts 32 on the third side of the supporting member 31 and the two abutting parts 34 located at the ends are placed on the five support blocks 122 on the third side of the box body 1 respectively. The two clamping parts 32 on the fourth side of the supporting member 31 are placed on the two support blocks 122 on the fourth side of the box body 1. At this time, the bottom surfaces of the multiple clamping parts 32 have multiple support blocks 122 that can abut one by one, so that the supporting member 31 is located on the upper supporting surface 121, as shown in FIG. Figures 5 to 7 shown.

[0080] When placing the supporting member 31 on the lower supporting surface 131, the supporting member 31 is rotated horizontally 180 degrees so that the third side of the supporting member 31 corresponds to the first side of the box body 1, and the four recesses 33 on the third side of the supporting member 31 correspond exactly to the four support blocks 122 on the first side of the box body 1, so that the support blocks 122 are located in the recesses 33, and the three support blocks 122 on the second side of the box body 1 are correspondingly inserted into the three recesses 33 on the fourth side of the supporting member 31, and the five recesses 33 on the first side of the supporting member 31 correspond exactly to the five support blocks 122 on the third side of the box body 1, and the three recesses 33 on the fourth side of the supporting member 31 correspond exactly to the three support blocks 122 on the fourth side of the box body 1. At this time, the plurality of support blocks 122 are located one by one in the plurality of recesses 33, the clamping portions 32 and the abutting portions 34 on the supporting member 31 are staggered from the support blocks 122, and the bottom surfaces of the plurality of clamping portions 32 can abut downward on the lower supporting surface 131, so that the supporting member 31 is located on the lower supporting surface 131, as shown in FIG. Figures 8 to 10 shown.

[0081] That is, the clamping portion 32 on the supporting member 31 is placed downwardly one-to-one opposite to the supporting block 122, so that the bottom surface of the clamping portion 32 can abut against the supporting block 122. Figure 7 , so that the supporting member 31 is supported by the upper supporting surface 121. Alternatively, the clamping portion 32 on the supporting member 31 can be placed downwardly facing the gap between two adjacent supporting blocks 122 and on the lower supporting assembly 13, so that the clamping portion 32 can pass through the gap between two adjacent supporting blocks 122 and abut against the lower supporting assembly 13. At this time, the supporting block 122 is located in the notch 33, referring to Fig.10 , so that the supporting member 31 is supported by the lower supporting surface 131. The difference in the number of the supporting blocks 122 located on the two opposite sides of the box body 1 and the difference in the number of the notches 33 located on the two opposite sides of the supporting member 31 are both one, so that all the clamping parts 32 on the supporting member 31 can be supported by the supporting blocks 122 when located on the upper supporting surface 121, thereby improving the support stability of the supporting member 32.

[0082] Therefore, the support member 31 can be rotated horizontally so that the top surface of the support block 122 can support the clamping portion 32 or the support block 122 and the clamping portion 32 are offset and located in the recess 33, so that the support member 31 is selectively located on the upper support surface 121 or the lower support surface 131, and the distance between the support member 31 and the bottom of the box body 1 is adjusted, that is, the height position of the support member 31 is adjusted, so as to adapt to a variety of different lengths of the fuel nozzle 44, and reduce the number of specifications of the loading box. In addition, the support member 31 can be taken out of the box body 1, which is convenient for the staff to clean and reduces the quality impact on the storage components such as the fuel nozzle 4.

[0083] In order to ensure the stability of the supporting member 31 on the upper supporting surface 121 and prevent the supporting member 31 from moving and sliding onto the lower supporting surface 131 when placed on the supporting block 122, the outer peripheral shape of the supporting member 31 in this embodiment is in close contact with the inner peripheral wall shape of the box body 1. In addition, positioning can also be performed between the bottom surface of the clamping portion 32 of the supporting member 31 and the top surface of the supporting block 122 through a concave-convex structure. Under the premise that the bottom surface of the clamping portion 32 and the top surface of the supporting block 122 are provided with a concave-convex structure, a certain gap can exist between the outer peripheral side of the supporting member 31 and the inner peripheral wall of the box body 1.

[0084] Both the supporting member 31 and the box body 1 can be provided with markings, so that the staff can determine whether the supporting member 31 is located on the upper support component 12 or the lower support component 13 by identifying the position of the marking, and also facilitate the staff to place the supporting member 31 on the box body 1 at the required position according to the position of the marking.

[0085] like Figure 4 As shown, the supporting member 31 includes a main board 311 and a plurality of receiving members 312 located at the bottom of the main board 311. The upper and lower ends of the receiving member 312 are connected, and the top opening of the receiving member 312 passes through the main board 311 upward, and the bottom opening of the receiving member 312 is smaller than the top opening of the receiving member 312, thereby forming a receiving portion 313. The receiving member 312 is formed into a cylindrical shape that is axially connected from top to bottom. The fuel injector 4 can be inserted from the top opening of the receiving member 312, and the bottom of the fuel injector 4 can be inserted from the bottom opening of the receiving member, so that the fuel injector 4 is placed vertically in the receiving member 312, which is convenient for taking and operating. In this embodiment, the plurality of receiving portions 313 are arranged at intervals, and a single loading box can accommodate a large number of fuel injectors 4 and there is no risk of parts collision during transportation.

[0086] Reference Fig.11 , Fig.11 for Figure 5 Cross-sectional view along the BB direction. The inner wall of the receiving portion 313 is provided with a plurality of steps 314 in the vertical direction, and the plurality of steps 314 gradually reduce the caliber of the receiving portion.
