DETAILED DESCRIPTION

(8) To further illustrate the supporting mechanism according to the present application, a further detailed description will be made hereinafter by taking a sorting machine employing this supporting mechanism as a preferred embodiment and in conjunction with drawings.

(9) Referring to FIGS. 2, 3 and 4, a sorting machine includes an upper cover 1 and a lower machine body 2 which are pivotally connected by a rotary shaft 01. A supporting mechanism 3 is mounted between the upper cover 1 and the lower machine body 2. The supporting mechanism 3 has a supporting body 31, and the supporting body 31 is provided with a rotary end 311 which is pivotally connected to the lower machine body 2 by a rotary shaft 21. An annular sliding slot 312 is formed on a section of surface, away from the rotary end 311, of the supporting body 31. The annular sliding slot 312 provides a route guidance for a locating pin 11 disposed on the upper cover 1. In the ring of the annular sliding slot 312, a U-shaped clamping slot 313 for hooking the above mentioned locating pin 11 is provided. A one-way deflecting locating valve plate 32 is provided in the annular sliding slot 312 at the position of an opening of the U-shaped clamping slot 313. The locating valve plate 32 is disposed on the supporting body 31 by a mounting rotary shaft 321 and configured to close the annular sliding slot 312. The locating valve plate 32 is provided with a reset force configured to ensure a tendency of the locating valve plate 32 to close the annular sliding slot 312. In this embodiment, this reset force is provided by a torsion spring 322 mounted on the mounting rotary shaft 321. The torsion spring 322 has one end fixed to the supporting body 31, and another end fixed to the locating valve plate 32. The locating valve plate 32 has a deflecting angle configured to ensure that a free end of the locating valve plate 32 deflects from one side of the opening of the U-shaped clamping slot 313 to another side of the opening of the U-shaped clamping slot 313 and allow the locating pin 11 to fall into the U-shaped clamping slot 313. In order that the supporting mechanism 3 can be effectively reset during the opening and closing process of the upper cover 1, a torsion spring 4 is provided between the supporting body 31 and the lower machine body 2. The torsion spring 4 is sleeved on the rotary shaft 21. The torsion spring 4 has one end fixed to the lower machine body 2, and another end hooked to a racetrack-shaped hole 314. The torsion spring 4 provides a reset force for the supporting body 31.

(10) Further, in order to ensure that the locating pin 11 may slide in the annular sliding slot 312 along a predetermined route during the opening process of the upper cover 1, a one-way deflecting guiding valve plate 33 configured to close the annular sliding slot 312 is provided in the annular sliding slot 312 at an initial position of the locating pin 11c. The initial position of the locating pin 11 is at one side of the guiding valve plate 33 to which the guiding valve plate 33 is allowed to deflect. The guiding valve plate 33 is disposed on the supporting body 31 by a second mounting rotary shaft 331 and configured to close the annular sliding slot 312. The guiding valve plate 33 is provided with a reset force configured to ensure a tendency of the guiding valve plate 33 to close the annular sliding slot 312. In this embodiment, the reset force is provided by a torsion spring 332 sleeved on the mounting rotary shaft 331. The torsion spring 332 has one end fixed to the supporting body 31 and another end fixed to the guiding valve plate 32. A one-way deflection direction of the guiding valve plate 33 is opposite to that of the locating valve plate 32. In this embodiment, the locating valve plate 32 can only deflect counterclockwise, and the guiding valve plate 33 can only deflect clockwise.

(11) As shown in FIGS. 4 to 7, which are respectively schematic views showing the supporting mechanism 3 at a plurality of critical positions during the opening and closing process of the upper cover 1 of the sorting machine, and during the opening process of the upper cover 1, the locating pin 11 slides along a locus shown by arrows in FIG. 5 under the guiding of the guiding valve plate 33 which can only deflect clockwise. When the locating pin 11 slides to the position of the locating valve plate 32, the locating valve plate 32 is pushed by the locating pin 11 to deflect counterclockwise. When the locating pin 11 reaches the position of the opening of the U-shaped clamping slot 313, the locating valve plate 32 does not deflect counterclockwise any more. At this time, if an acting force for opening the upper cover is removed, the locating pin 11 automatically falls into the U-shaped clamping slot 313, thus achieving a position-limiting function in the opened state of the upper cover. At this time, the locating valve plate 32 is reset under the action of the reset spring 322 since the locating valve plate 32 is not pushed by the locating pin 11, as shown in FIG. 6.

(12) In the case that the upper cover is required to be closed, the upper cover 1 is slightly lifted up in order to lift the locating pin 11 up from the U-shaped clamping slot 313. At this time, the locating pin 11 can only slide along a locus shown in FIG. 7 since the annular sliding slot 312 is closed by the locating valve plate 32. When the locating pin 11 slides to the guiding valve plate 33 configured to close the annular sliding slot 312, the guiding valve plate 33 is pushed by the locating pin 11 to deflect clockwise until the locating pin 11 completely passes a free end of the guiding valve plate to return to the initial position thereof, thus completing the entire closing operation of the upper cover. At this time, the guiding valve plate is also automatically reset under the action of the reset force.

(13) The embodiments described hereinabove are only preferred embodiments of the present application. It should be noted that, the above preferred embodiments should not be interpreted as a limitation to the present application, and the protection scope of the present application is defined by the claims of the present application. For those skilled in the art, many improvements and modifications may be made to the present application without departing from the principle of the present application, and these improvements and modifications are also deemed to fall into the protection scope of the present application.
