Abstract

A material loading device includes a main body defining a receiving cavity and an opening. The receiving cavity receives materials. The main body defines a buckle groove at the opening. A buckle rod movably coupled to the main body at the opening buckles into the buckle groove. A foolproof mechanism is arranged on the main body. A thimble of the foolproof mechanism is slidably coupled to the main body. One end of the thimble is located in the buckle groove. When the buckle rod is buckled into the buckle groove, the buckle rod drives the thimble to slide relative to the main body. A display member of the foolproof mechanism is coupled to the thimble. The main body defines a plurality of recesses corresponding to the display member. The thimble drives the display member to slide relative to the recesses to switch the display member displayed through the recesses.

First claim

What is claimed is:

1. A material loading device comprising:
a main body defining a receiving cavity and an opening communicating with the receiving cavity, the receiving cavity configured for receiving materials, the main body further defining a buckle groove at the opening;
a buckle rod movably coupled to the main body at the opening and configured to buckle into the buckle groove to resist against the materials in the receiving cavity; and
a foolproof mechanism arranged on the main body; wherein:
the foolproof mechanism comprises a thimble and a display member;
the thimble is slidably coupled to the main body;
one end of the thimble is located in the buckle groove;
when the buckle rod is buckled into the buckle groove, the buckle rod drives the thimble to slide relative to the main body;
the display member is coupled to the thimble;
the display member has different colored areas;
the main body defines a plurality of recesses corresponding to the display member; and
the thimble drives the display member to slide relative to the recesses to switch the colored areas displayed through the recesses.

2. The material loading device of claim 1 , further comprising a handle mechanism movably coupled to the main body, wherein:
the foolproof mechanism further comprises a linkage mechanism, the linkage mechanism comprises a lever and a push rod;
the lever is rotationally coupled to the main body;
one end of the lever is movably coupled to the thimble, and another end of the lever is movably coupled to the push rod;
the thimble drives the lever to drive the push rod to hold or release the handle.

3. The material loading device of claim 2 , wherein:
the foolproof mechanism further comprises a reset member;
one end of the reset member is fixed to the main body, and another end of the reset member resists against the thimble toward an outer side of the buckle groove.

4. The material loading device of claim 3 , wherein:
a sliding channel communicating with the buckle groove is defined in a wall of the main body;
the thimble is slidably received in the sliding channel; and
the reset member is arranged at an end of the sliding channel away from the buckle groove.

5. The material loading device of claim 4 , wherein:
an end of the thimble located in the buckle groove comprises a limiting portion; and
the limiting portion protrudes radially outward to limit a sliding distance of the thimble in the sliding channel.

6. The material loading device of claim 2 , wherein:
the handle mechanism comprises a handle and two connecting rods respectively coupled to two ends of the handle;
the main body comprises two oppositely facing connecting seats; and
an end of each connecting rod away from the handle is rotationally coupled to the corresponding connecting seat.

7. The material loading device of claim 6 , wherein:
the handle comprises a buckle portion;
the buckle portion defines a buckle hole; and
the lever is driven by the thimble to drive the push rod into or away from the buckle hole.

8. The material loading device of claim 7 , wherein:
the connecting seat comprises two clamping plates arranged at an angle;
a distance between the two clamping plates gradually decreases along a direction from a surface of the main body to away from the main body; and
the connecting rod is rotationally coupled between the two clamping plates.

9. The material loading device of claim 1 , further comprising a plurality of loading plates, wherein:
the material loading plates are adapted to carry the materials;
two opposite inner walls of the main body define a plurality of slots;
two sides of each of the loading plates are respectively inserted into the corresponding slots on the two opposite inner walls; and
the buckle rod is used to resist against the loading plates inserted into the slots.

10. The material loading device of claim 1 , wherein:
the display member comprises two colored areas;
the two colored areas are arranged on a surface of the display member at intervals;
the recesses are arranged on the main body at intervals;
one of the two colored areas is displayed through the recesses when the buckle rod is not buckled; and
another one of the two colored areas is displayed through the recesses when the buckle rod is buckled.

11. A material loading device comprising:
a main body defining a receiving cavity and at least one opening communicating with the receiving cavity, the receiving cavity receiving materials, the main body further defining at least one buckle groove at the opening;
a buckle rod movably coupled to the main body at the opening and configured to buckle into the buckle groove to resist against the materials in the receiving cavity;
a foolproof mechanism arranged on the main body; and
a handle assembly arranged on the main body, the handle assembly comprising a handle and two connecting rods respetively coupled to two ends of the handle, wherein:
the main body comprises two oppsitely facing connecting seats, each connecting seat comprises two clamping plates arranged at an angle, a distance between the two clamping plates decreases along a direction from a surface of the main body to away from the main body, an end of each connecting rod is rotationally coupled between the two clamping plates;
when the buckle rod is buckled into the buckle groove, the foolproof mechanism displays one of a first colored area and a second colored area to indicate that the buckle rod is buckled into the buckle groove;
when the buckle rod is not buckled into the buckle groove, the foolproof mechanism displays the other one of the first colored area and the second colored area to indicate that the buckle rod is not buckled into the buckle groove; and
when an external force is not applied to the handle, the handle falls to a surface of the main body.
