In the invention, after the scroll spring 46 is forced up, if the dial plate 6 is not dialed, the scroll spring 46 is always in a forced up state and cannot be released; not opening cabinet door 1 through stirring board 6 all the time, volute spiral spring 46 just is in last power all the time, stirs board 6 and opens cabinet door 1 until the execution, and volute spiral spring 46 just can release, can store up power once more when opening next time and closing cabinet door 1, and open cabinet door 1 through the tradition and do not have the influence.

The specific working process is as follows: as shown in a of fig. 14, when the cabinet door 1 is fully opened and the spiral spring 46 has no stored force, the first limiting rod 47 is engaged with the first engaging groove 54 formed on the first mounting case 43; the second limiting rod 52 is matched with a fourth clamping groove 61 on the third hinge shaft 36; a gap is formed between the first stopper 48 and the second stopper 49; one end of the second limiting rod 52, which is not provided with the inclined surface 75, is in press contact with and matched with the inner circular surface of the second mounting shell 44; the third stopper 50 and the fourth stopper 51 are in contact fit, and the fifth stopper 62 and the sixth stopper 63 are in contact fit.

When the cabinet door 1 designed by the invention is used, when the cabinet door 1 is closed from an open state, the cabinet door 1 can drive the first fixed plate 8 to swing relative to the second fixed plate 10 arranged on the cabinet plate 14, the first fixed plate 8 swings to drive the third hinged plate 12 and the fourth hinged plate 13 to swing, the third hinged plate 12 swings to drive the two first hinged plates 9 to swing, the fourth hinged plate 13 swings to drive the second hinged plate 11 to swing, and the sixth spring 34 is compressed; meanwhile, when the cabinet door 1 is closed, the cabinet door 1 can drive the first mounting shell 43 to rotate, the first mounting shell 43 rotates to drive the second mounting shell 44 to rotate together through the first limiting rod 47, the volute spiral spring 46 is compressed to exert force in the rotating process, and the third limiting block 50 and the fourth limiting block 51 are separated in the exerting force process; as shown in b in fig. 14, when the cabinet door 1 is opened to 45 degrees, the end of the second limiting rod 52 without the inclined surface 75 is inserted into the second slot 57 opened on the second mounting shell 44 under the action of the fourth spring 69, and the end of the second limiting rod 49 with the inclined surface 75 is disengaged from the fourth slot 61; as shown in c in fig. 14, when the door is closed to a degree greater than 45 degrees, the cabinet door 1 is automatically closed under the action of the sixth spring 34, the third mounting shell 45 rotates together with the first mounting shell 43 and the second mounting shell 44 under the action of the second limiting rod 52 and the first limiting rod 47 in the closing process, and the fifth limiting block 62 is separated from the sixth limiting block 63. When the cabinet door 1 is closed, if the dial plate 6 is not dialed when the cabinet door 1 is opened, the first mounting shell 43, the second mounting shell 44 and the third mounting shell 45 are relatively static and are driven along with the rotation of the cabinet door 1, when the cabinet door 1 is in any one state of a non-closed state, the two transmission plates 78 are not matched with the two push plates 38, and the dial plate 6 cannot play a role in the states; only when the cabinet door 1 is in the fully closed state, the two driving plates 78 are engaged with the two pushing plates 38.

As shown in d in fig. 14, when the cabinet door 1 is opened, the dial plate 6 is manually shifted, the dial plate 6 is shifted to pull the first pull rope 2, the first pull rope 2 pulls the two second pull ropes 40 to slide, the two second pull ropes 40 slide to drive the two push plates 38 to slide, the two push plates 38 slide to drive the two transmission plates 78 to slide, the two transmission plates 78 slide to drive the first limiting rod 47 and the second limiting rod 52 to slide, so that the first limiting rod 47 is separated from the first slot 54, the end of the second limiting rod 52 having the inclined surface 75 is inserted into the third slot 60, and the end of the second limiting rod 52 not having the inclined surface 75 is separated from the first slot 54 opened on the second mounting shell 44; at this time, under the action of the spiral spring 46, the second mounting shell 44 rotates reversely relative to the first mounting shell 43, and at the same time, under the action of the second spring 65, the second mounting shell 44 also rotates reversely relative to the first mounting shell 43 by a certain angle, so that the first engaging groove 54 and the second limiting rod 52 formed on the second mounting shell 44 are dislocated, as shown in fig. 14 e, the first limiting block 48 contacts the second limiting block 49; then, the dial plate 6 is released, and the second mounting shell 44 drives the first mounting shell 43 to rotate reversely through the first limiting block 48 and the second limiting block 49 under the action of the volute spring 46, that is, the cabinet door 1 is driven to rotate reversely; in the rotating process, the third limiting block 50 and the fourth limiting block 51 gradually approach each other, as shown in f in fig. 14, after the cabinet door 1 is driven to rotate by 45 degrees, the third limiting block 50 and the fourth limiting block 51 contact each other, and simultaneously, the volute spiral spring 46 is released, so that the cabinet door 1 has a certain opening speed and can smoothly pass through 45 degrees; after the angle of 45 degrees is exceeded, under the action of the sixth spring 34, the cabinet door 1 continues to swing, the cabinet door 1 drives the first mounting shell 43 to rotate, the first mounting shell 43 drives the second mounting shell 44 to rotate through the second spring 65, the second mounting shell 44 drives the third mounting shell 45 to rotate through the cooperation of the third limiting block 50 and the fourth limiting block 51, at this time, the third mounting shell 45 continues to be driven to rotate, the telescopic inner rod 74 in the second limiting rod 52 passes through the third slot 60 under the action of the inclined plane 75 on the clamping block 76, and in the process of passing through the third slot 60, the telescopic inner rod 74 is extruded and retracted to the inner side of the telescopic outer sleeve 77, when the fifth limiting block 62 contacts with the sixth limiting block 63 in the rotating process of the third mounting shell 45, the fifth limiting block 62 limits the third mounting shell 45, and simultaneously, one end of the second telescopic rod with the inclined plane 75 is matched with the fourth slot 61, and is inserted into the fourth slot 61 under the action of the fourth spring 69 to recover to the initial state, in the process that the cabinet door 1 continues to swing, the first limiting block 48 and the second limiting block 49 are gradually separated, and after the cabinet door 1 is completely opened, the first telescopic rod also just swings into the first slot 54 opened on the first mounting shell 43, and is inserted into the first slot 54 under the action of the third spring 68, so as to be restored to the initial state.
