Detailed Description

The accompanying drawings illustrate embodiments of the present disclosure and it is to be understood that the disclosed embodiments are merely examples of the disclosure, which can be embodied in various forms, and therefore, specific details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

Further, the expressions indicating directions (for example, upper and lower) for explaining the operation and configuration of each member in the embodiment are not absolute but relative, and although these indications are appropriate when each member is in the position shown in the drawings, when the position is changed, these directions should be interpreted differently to correspond to the change.

In some embodiments, referring to fig. 5-8, the graphite boat 100 includes a graphite body 1 and a graphite baffle 2. The graphite body 1 has an inner peripheral surface 11, an outer peripheral surface 12, an upper surface 13, and a first groove 14, the first groove 14 has a bottom surface 141, the upper surface 13 connects the inner peripheral surface 11 and the outer peripheral surface 12, projections of the inner peripheral surface 11, the outer peripheral surface 12, and the bottom surface 141 in the axial direction L are concentric semicircular, and the first groove 14 is open at the inner peripheral surface 11 and the upper surface 13. The graphite baffle 2 has a plate body 21, a projection of an outer peripheral surface 211 of the plate body 21 in the axial direction L is semicircular, the plate body 21 is accommodated in the first groove 14 at a peripheral edge 212, and the outer peripheral surface 211 of the plate body 21 contacts a bottom surface 141 of the first groove 14. The graphite baffle 2 further has two limiting parts 22, each limiting part 22 has a first limiting section 221, the first limiting section 221 extends radially outward from one end of the top surface 213 of the plate body 21, and the first limiting section 221 shields the corresponding first groove 14 from above at the upper surface 13 of the graphite body 1 and abuts against the upper surface 13 of the graphite body 1. By providing each limiting portion 22 with the first limiting section 221, after the graphite baffle 2 is installed in the first groove 14, the two first limiting sections 221 abut against the upper surface 13 of the graphite body 1, so that no matter whether the graphite baffle 2 tries to rotate counterclockwise or clockwise around the axial direction L, the graphite baffle 2 is limited by one of the first limiting sections 221 abutting against the upper surface 13 of the graphite body 1, thereby improving the circumferential positioning stability of the graphite baffle 2.

In some embodiments, referring to fig. 5 to 8, each of the position-limiting portions 22 further has a second position-limiting section 222, the second position-limiting section 222 extends downward from the radially outer end of the first position-limiting section 221 in the circumferential direction outside the outer circumferential surface 12 of the graphite body 1, and the second position-limiting section 222 is spaced apart from the outer circumferential surface 211 of the plate body 21 to receive a portion of the graphite body 1. Similarly, no matter whether the graphite baffle 2 tries to rotate counterclockwise or clockwise around the axial direction L, one of the second limiting sections 222 is limited by abutting against the outer circumferential surface 12 of the graphite body 1, so that the circumferential positioning stability of the graphite baffle 2 is further improved.

In some embodiments, referring to fig. 5 to 7, the inner side surface 222a of each second limiting section 222 is an arc surface protruding toward the outer circumferential surface 211 of the plate body 21; the distance between the inner side surface 222a of the second stopper section 222 and the outer peripheral surface 211 of the plate body 21 gradually increases from the upper end of the inner side surface 222a to the lower end of the inner side surface 222 a; the distance between the inner surface 222a of the second stopper 222 and the outer circumferential surface 211 of the plate body 21 is larger than the diameter of the outer circumferential surface 12 of the graphite body 1. Therefore, when the graphite baffle 2 is mounted in the first groove 14, the inner side surface 222a of the second limiting section 222 plays a guiding role.

In some embodiments, referring to fig. 5-7, the two position-limiting portions 22 of the graphite baffle 2 are mirror images of each other. The graphite baffle 2 is simple to manufacture and design, and can be still installed in the first groove 14 after being rotated back and forth by 180 degrees in the drawing, thereby being beneficial to simplifying the installation operation of the graphite baffle 2.

In some embodiments, referring to fig. 5 to 7, a concave portion 23 is formed between the top surface 213 of the plate body 21 and the two limiting portions 22, which is advantageous for reducing the weight of the graphite baffle plate 2.

In some embodiments, referring to fig. 5-7, the top surface 213 of the plate body 21 is coplanar with the upper surface 13 of the graphite body 1, which facilitates visual confirmation of whether the graphite baffle 2 is properly positioned in the first groove 14, and if foreign matter is in the first groove 14, the top surface 213 of the plate body 21 is not coplanar with the upper surface 13 of the graphite body 1.

In some embodiments, with reference to fig. 7 and 8, the graphite baffle plate 2 further has a protrusion 24, the protrusion 24 protruding radially outward from the plate body 21 and extending in the circumferential direction and the axial direction L, the protrusion 24 having an arc shape in the circumferential direction smaller than the circumference of the plate body 21; the graphite body 1 is provided with a second groove 15, the second groove 15 extends outwards from the bottom surface 141 of the first groove 14 in the radial direction, and the protrusion 24 of the graphite baffle 2 is accommodated in the second groove 15. The cooperation of the protrusion 24 and the second groove 15 not only realizes the radial positioning of the graphite baffle 2 in the graphite body 1, but also realizes the limiting effect of the graphite baffle 2 in the circumferential direction.

In some embodiments, referring to fig. 7, the tab 24 of the graphite baffle plate 2 is centrally disposed on the perimeter of the plate body 21. At this time, the manufacturing and design of the protrusion 24 are simple, and after the graphite baffle 2 is rotated back and forth by 180 degrees in the drawing, the protrusion 24 can still be installed in the second groove 15, thereby facilitating the simplification of the installation operation of the graphite baffle 2.

In some embodiments, referring to fig. 4 to 8, the first grooves 14 are two and are respectively disposed at two ends of the graphite body 1 in the axial direction L; the number of the graphite baffle plates 2 is two and the graphite baffle plates are respectively accommodated in the first grooves 14. Therefore, the graphite body 1 and the graphite baffle 2 are convenient to maintain and replace respectively, and the cost is reduced.

In some embodiments, referring to fig. 4-8, the two first grooves 14 are identical and the two graphite baffles 2 are identical. Therefore, the graphite baffle plate 2 is convenient to manufacture, design and install, and the cost is reduced.

The above detailed description is used to describe a number of exemplary embodiments, but is not intended to limit the combinations explicitly disclosed herein. Thus, unless otherwise specified, various features disclosed herein can be combined together to form a number of additional combinations that are not shown for the sake of brevity.
