The hinge assembly 6 is mounted in the recess 41 of the small door and the recess 51 of the side panel, and is positionally switchable between the first hanging table 44, 53 and the second hanging table 43, 54. When the small door 5 is pulled, the hinge assembly 6 is fitted to the second hanging tables 43, 54 at which time the small door can be rotated relative to the side plates to open the small door. When the small door 5 is pressed, the hinge assembly 6 is fitted on the second hanging tables 44, 53, at which time the small door cannot be rotated relative to the side panels, and the hinge assembly is hidden in the small door and the side panels.

The structure of the hinge assembly 6 is as shown in Figs. 6-9, and the hinge main body 63 has two sets (two rows) of hinge holes 631. Each hinge hole 631 has a limit 632 and an inverse limit 633 at one end. That is, the top end of the hinge body is provided with a limit position 632 and a reverse limit position 633, and the bottom end of the hinge body is also provided with a limit position 632 and an inverse limit position 633. The contingency 632 and the inverse 633 are lobes that are spaced apart and substantially parallel to each other. It should be understood that other suitable limit structures may be employed to achieve the same function.

The hinge main body 63 is engaged with the hinge pin 62 through the hinge hole 631. As shown in FIG. 8, the main structure of the hinge pin 62 is a cylinder 621. One end of the cylinder 621 has a radially outwardly protruding positioning key 622. The positioning key cooperates with the positioning groove 612 in one of the hinge holes of the upper hinge seat. The hinge pin is constrained to rotate in the hinge hole of the upper hinge seat. A locating ring 624 is also provided at one end of the cylinder 621 for securing the hinge pin to the hinge base. Also provided on the cylinder 621 is a hole 623 that allows the hinge pin 62 to be locally deformed. The two hinge pins 62 are also connected to the hinge holes 611 of the upper hinge base 61 and the lower hinge base 61, respectively. In this embodiment, the upper hinge base and the lower hinge base are identical, and therefore the same reference numerals are used. It should be understood that those skilled in the art can modify the upper hinge base and the lower hinge base to be different from each other in the teachings of the present invention. The hinge base 61 described above will be described in detail as an example.

The upper hinge base 61 has a body. The top end of the upper hinge base 61 is provided with three hinge holes 611 which are spaced apart from each other. One of the hinge holes 611 is provided with a positioning groove 612. The hinge base 61 has elastic arms 613 on both sides of the body. The resilient arms 613 are angled outward. The end of the elastic arm 613 is provided with a hook 614. The hook 614 is substantially C-shaped or L-shaped. A bottom surface of the C-shape or a corner of the L-shape is provided with a guide surface 614a, and both ends of the C-shape or the L-shape are respectively provided with a stopper surface 614b and a hook portion 614c. The hook 614 cooperates with the first hanging table and the second hanging table to realize the up and down displacement of the hinge assembly 6 relative to the small door or the side plate. Specifically, when the small door 5 is pulled, the hook 614 passes through the inclined surface 53a in the groove, the guiding surface 614a of the hook cooperates with the inclined surface 53b, the stopping surface 614b of the hook cooperates with the flat surface 54a, and the hanging portion 614c of the hook Cooperating with the inclined surface 54b to prevent the upper hinge base 61 from coming off the small door. At this time, the small door can be rotated relative to the side panel to open the small door. When the small door 5 is pressed, the hinge assembly 6 is fitted on the second hanging table 53, at which time the small door cannot be rotated relative to the side plate, and the hinge assembly is hidden in the small door and the side plate.

The front side or the rear side of the upper hinge base 61 is further provided with a positioning groove 615. The positioning groove 615 and the positioning rib 52 cooperate to limit the left and right displacement of the upper hinge seat 61 on the side plate or the small door after installation, and protect the movement thereof. stability. In addition, the upper hinge base 61 is correspondingly provided with a limit position 617 and a reverse limit position 616 which cooperate with the hinge pin 63. Specifically, the limit position 617 and the inverse limit position 616 may be disposed between adjacent two hinge holes. The contingency 617 and the inverse limit 616 are ribs that extend in a direction parallel to the axis of the hinge. The overall assembly diagram of the hinge assembly 6 is as shown in FIG. 6. Obviously, when the upper hinge base 61 and the hinge main body 63 are in a substantially parallel state, due to the cooperation of the constrained position structure and the reverse limit structure, When the upper hinge base 61 is rotated by a certain angle with respect to the hinge main body 63 by the hinge pin 62, a certain force is required to pass over the limit structure. This ensures that the stability of the integral hinge assembly 6 when the small door is pressed does not cause easy deflection of the upper hinge base 61.

The overall mechanism movement process of this embodiment is as shown in Figs. 10A to 10D. Initially, the small door 5 and the side panel 4 remain in use, and the position of the hook 614 of the upper hinge base 61 of the hinge assembly 6 is as shown in FIG. 4, at which time the hinge assembly 6 can transmit the lateral force of the small door 5 or the side panel 4. , to maintain the balance of the force deformation of the two. When the small door 5 needs to be opened, the small door 5 is pulled up, so that the hook 614 of the upper hinge seat 61 of the hinge assembly 6 reaches the position shown in FIG. 5, and the hook 614 needs to pass over the first hanging table and then contact the second during operation. Hanging the table, so the force of pulling has a light-------------- It is especially important that the first hanging platform also approaches or contacts the hook 614 at this time, so that the upper hinge seat 61 does not easily return to the initial position due to gravity or external force, so that the operator can continue the subsequent operation without maintaining the pulling force. After the lifting action is completed, the hinge main body 63 completely protrudes from the groove 41 of the side plate 4 and the groove 51 of the small door 5, and then the small door 5 can be turned over to open it. It should be noted that the turning process In the middle, the upper and lower hinge pins 62 may be the first pivoting shaft, and the inverted gate 5 and the side panel 4 are parallel and aligned.

11 to 13D are views showing the structure of a second embodiment of the hinge structure of the present invention. 11 to 13D, the present embodiment is the same as the hinge assembly 6 of the above embodiment, except that in the present embodiment, the recess 5a1 of the small door 5a is disposed such that the upper hinge seat is fixed in the recess. Not moving, and the depth of the groove 4a1 of the side plate 4a is deeper than the depth of the corresponding groove 41 of the first embodiment, so that a part of the hinge assembly 6 includes a part or all of the lower hinge seat and the hinge body and optionally A portion of the upper hinge seat is movable up and down within the recess 41.

Specifically, only one hanging platform 5a2 is respectively disposed on both side walls of the recess 5a1 of the small door 51a. The hanging table 5a2 cooperates with the hook of the upper hinge seat to fix the upper hinge seat in the recess 5a1 of the small door. A first hanging table 4a2 and a second hanging table 4a3 are provided in the recess 4a1 of the side plate 4a. The structures of the first hanging platform 4a2 and the second hanging platform 4a3 are the same as those of the first hanging platform 44 and the second hanging platform 43 in the first embodiment, and will not be described in detail herein.

The overall mechanism movement process of this embodiment is as shown in Figs. 13A to 13D. Initially, the small door 5a and the side panel 4a remain in use, and the position of the hook 614 of the upper hinge base 61 of the hinge assembly 6 is as shown in Fig. 11, at which time the hinge assembly 6 can transmit the lateral force of the small door 5a or the side panel 4a. , to maintain the balance of the force deformation of the two. When it is necessary to open the small door 5a, the small door 5a is pulled up, so that the hook 614 of the lower hinge seat 61 of the hinge assembly 6 reaches the position shown in Fig. 12, and the hook 614 needs to pass over the first hanging table and then contact the second during operation. Hanging the table, so the force of pulling has a light-------------- It is especially important that the first hanging platform also approaches or contacts the hook 614 at this time, so that the lower hinge seat 61 does not easily return to the initial position due to gravity or external force, so that the operator can continue the subsequent operation without maintaining the pulling force.
