Figure 1 shows a hidden hinge of the prior art and its mounting on the door and side panels. As shown in fig. 1, the hinge assembly 3 includes a hinge main body 32, an upper hinge base 31, and a lower hinge base 33, the hinge main body 32 having upper and lower hinge pins 321, 322, a groove 312 on the upper hinge base 31 accommodating the hinge pin 321, and a groove 332 on the lower hinge base 33 accommodating the hinge pin 322. The side of the upper hinge seat 31 is provided with a hanging platform 311, and the side of the lower hinge seat 33 is provided with a hanging platform 331. The side wall of the door 2 is provided with the hole 21, and the side wall of the side plate 1a is provided with the hole 1a1, so that when the upper hinge seat 31 and the door 2 are assembled, the side wall of the door 2 is deformed outwards due to the extrusion of the hanging table 311, so that the hanging table 311 can reach the hole 21, and the upper hinge seat 31 is prevented from being easily separated from the groove of the door 2. Similarly, when the lower hinge seat 33 and the side plate 1a are assembled, the side wall of the side plate 1a will be deformed outward due to the pressing of the hanging table 331, so that the hanging table 331 can reach the hole 1a1, thereby preventing the upper hinge seat 33 from being easily removed from the groove of the side plate 1 a. In the scheme, the upper hinge seat and the lower hinge seat are installed in the container through the matching of a lug boss on the hinge seat, a side plate and an installation hole on the door. However, when the installation is completed, the installation hole and the boss on the hinge base are still visible in appearance of the container.

Fig. 2 to 5 show a first embodiment of the hinge fixing structure of the present invention. Compared with the fixing structure shown in fig. 1, the appearance is improved due to the elimination of the holes in the side walls, and the strength of the hinge mounting portion is also improved to some extent.

As shown in fig. 2-3, the hinge assembly 3 is similar in construction to that of fig. 1. In contrast, the upper hinge base 31 has two

branches

311 and 312 with bosses for positioning, and the lower hinge base 33 has two

branches

331 and 332 with bosses.

Branches

311 and 312 are similar in structure to

branches

331 and 332, and only

branches

331 and 332 on either side of the lower hinge base will be described as examples. As shown in fig. 2 and 3, the

branches

331 and 332 are elastic pieces integrally extended from the two

sides

33a and 33b of the lower hinge base near the lower surface 33c of the lower hinge base, and

bosses

331a and 332a are provided at the ends of the elastic pieces. The

bosses

331a, 332a are adapted to mate with a hanging shelf in a recess 1a1 in the side panel 1a when the lower hinge mount 31 is installed in the recess so that the lower hinge mount 33 will not fall out of the side panel 1a after installation, as will be described in more detail below.

The groove 1a1 is located between two side walls 1a20 and 1a21 of the side plate 1a, and the groove 1a1 is provided with positioning ribs 1a11 and 1a12 and hanging platforms 1a13 and 1a14 for limiting. As shown more clearly in fig. 3, the positioning ribs 1a11, 1a12 are two columns extending from the bottom surface of the groove, and the cross-sectional shape of the columns can be selected as required, and in this embodiment, the cross-sectional shape of the columns is rectangular. The distance between the positioning rib 1a11 and the positioning rib 1a12 may be determined according to the distance between the two

branches

331 and 332 on the lower hinge base 33, so that the hinge base is prevented from moving left and right by the cooperation of the positioning rib and the branches. The hanging stands 1a13, 1a14 are tabs extending from both sides of the mouth of the groove. When the lower hinge base is mounted into the side panel 1a, the

bosses

331a, 332a are engaged with the hanging stands 1a13, 1a14, respectively, so that the lower hinge base does not come out from the mouth of the recess 1a 1.

Similarly, the side door 2 has a groove 21 between both side walls, and the groove 21 has the same structure as the groove 1a1, i.e., positioning

ribs

211, 212 and hanging

bases

213, 214 are provided therein, and the hanging

bases

213 and 214 are respectively engaged with the

branches

311 and 312 so that the upper hinge base does not come out of the mouth of the groove 21.

Fig. 4 and 5 illustrate the installation of the hinge assembly 3 provided with the hinge fixing structure into the side plate 1a or the door 2, here, only the installation of the above hinge housing 31 to the door 2 is taken as an example. When the upper hinge base 31 is installed in the recess 21 of the door 2, the

positioning ribs

211, 212 will first contact the upper hinge base 31 and make it unable to move easily in the left-right direction, at this time, because the hanging

platforms

213, 214 on the recess 21 block the

branch

331 and 332 from entering the recess 21, the

branch

331, 332 will bend and deform inwards due to its own elasticity, as shown in fig. 3, when the distance between its two sides is not larger than the distance between the hanging

platforms

213, 214, it can enter the recess 21. As shown in fig. 5, when the upper hinge base 31 is completely fitted into the recess 21 of the door 2, the hanging stands 213 and 214 restrict the bosses of the

branches

331 and 332 from moving toward the mouth of the recess, thus achieving the mounting of the upper hinge base 31 to the door 2. The lower hinge base 3 and the side plate 1a are mounted in the same manner, and will not be described in detail.

Fig. 6 to 9 show another embodiment of the hinge fixing structure of the present invention. In the present embodiment, the hinge assembly 3 is similar in structure to the above-described embodiments, except for the fixing structure of the hinge. As shown in fig. 6 and 7, the upper hinge base 31 has hanging

bases

314 and 315 and an elastic piece 313 for positioning, and the lower hinge base 33 also has hanging

The hanging table is matched with the hanging grooves in the grooves of the door and the side plate, so that when the upper hinge seat and the lower hinge seat are installed on the door and the side plate, the hinge seats cannot be separated from the groove openings.

As shown in the figure, the door 2 has a groove 21 between two side walls, and hanging

grooves

215, 216 for limiting are arranged in the groove 21, and the hanging grooves are L-shaped. The side plate 1a is provided with a groove 1a1 between the two side walls 1a20 and 1a21, and hanging grooves 1a15 and 1a16 are arranged in the groove 1a 1. The cross-sectional shape of the hanging

grooves

215 and 216 matches the shape of the hanging table, and the distance between the hanging

grooves

215 and 216 is set according to the distance between the hanging tables 314 and 315, so that the hanging tables 314 and 315 can be snapped into the hanging

grooves

215 and 216 and cannot be pulled out of the hanging grooves after the installation is completed. The hanging grooves 1a15, 1a16 and the hanging

grooves

When the upper hinge base 31 is fitted into the recess 21 of the door 2, the upper hinge base 31 is slightly shifted to the right side first so that the hanging

platforms

314, 315 can enter the hanging

grooves

215, 216 from the side, and at this time, the elastic piece 313 of the upper hinge base 31 is deformed downward due to being blocked by the structure of the side of the recess 21, as shown in fig. 8. At this time, the upper hinge base 31 is continuously pushed to the left side, the hanging

platforms

314 and 315 enter the hanging

grooves

215 and 216, and at this time, the elastic piece 313 is no longer blocked by the side structure of the groove 21 and restores to the free form, so that the elastic piece 313 can prevent the upper hinge base 31 from moving to the right side, and the upper hinge base 31 cannot be easily separated from the hanging groove, namely the upper hinge base 31 cannot be easily separated from the groove 21, thereby realizing the installation of the upper hinge base 31 to the door 2.
