[0018] The following is a further detailed description of the specific embodiments of the present invention. It should be understood that the description of the present invention herein is not intended to limit the protection scope of the present invention.

[0019] like Figures 1 to 4 As shown, it is a schematic diagram of the structure of a mask plate transport box that can prevent the sealing ring from overflowing provided by the utility model. The mask plate transport box that can prevent the sealing ring from overflowing includes a base 10, an upper cover 20 arranged on one side of the base 10, and a sealing component 30 arranged between the base 10 and the upper cover 20. It is conceivable that the mask plate transport box that can prevent the sealing ring from overflowing should also include some other functional components, such as connecting components, assembly components, etc., which are all existing technologies known to those skilled in the art and will not be elaborated here.

[0020] The base 10 includes a bottom plate 11, a plurality of support units 12 symmetrically arranged on the bottom plate 11, and at least one limit card 13 arranged on the bottom plate 11. The bottom plate 11 can be matched with the mask plate transported by the mask plate transport box that can prevent the sealing ring from overflowing. The support unit 12 is used to set the transported mask plate above the bottom plate 11 to reduce friction damage and contamination of the mask plate. The limit card 13 is used to limit the position of the mask plate to ensure the stability of the mask plate during transportation. It is conceivable that some other functional structures are also arranged on the base 10, such as a connecting component for connecting and closing with the upper cover 20. The base 10 itself is a prior art and will not be described in detail here.

[0021] The upper cover 20 includes an upper cover body 21 and a bottom plate mounting groove 22 disposed on the side of the upper cover body 21 facing the bottom plate 11. The inner contour of the bottom plate mounting groove 22 is matched with the outer contour of the bottom plate 11, and the bottom plate 11 is accommodated in the bottom plate mounting groove 121 when the mask plate transport box is closed. It is conceivable that the upper cover 20 should also include some other functional components, such as a crane connection component for connecting to a crane, a closing connection component for closing with a base, etc. The upper cover 20 itself is a prior art well known to those skilled in the art, and will not be described in detail here.

[0022] The sealing assembly 30 includes a sealing installation unit 31 disposed on the bottom plate 11 , a sealing ring 32 accommodated in the sealing installation unit 31 , and an upper cover sealing rib 33 fixedly disposed on a side of the upper cover 20 facing the bottom plate 11 .

[0023] The sealing installation unit 31 includes a sealing installation groove 311 arranged along the four sides of the base 10, a limiting baffle 312 arranged along the outer contour of the sealing installation groove 311, and a plurality of positioning protrusions 313 arranged on the side wall of the base 10 along the outer contour of the base 10.

[0024] The shape of the sealing installation groove 311 matches the outer contour shape of the bottom plate 11, and the sealing installation groove 311 is arranged along the outer contour edge of the bottom plate 11. The sealing installation groove 311 is used to accommodate and install the sealing ring 32.

[0025] The limit baffle 312 is fixedly arranged along the outer contour of the sealing installation groove 311 at the outer contour edge of the sealing installation groove 311. When the sealing ring 32 is accommodated in the sealing installation groove 311, the height of the limit baffle 312 is higher than the height of the sealing ring 32. The limit baffle 312 is used to prevent the sealing ring 32 from being squeezed when the base 10 and the upper cover 20 are closed, thereby preventing the sealing ring 32 from overflowing, affecting the overall sealing of the mask plate transport box, and causing the external environment to pollute the mask plate.

[0026] A plurality of the positioning protrusions 313 are fixedly arranged on the side wall of the bottom plate 11, and the plurality of the positioning protrusions 313 are arranged at equal intervals along the outer contour edge of the bottom plate 11. The positioning protrusions 313 are arranged along the vertical direction of the bottom plate 11. When the sealing ring 32 is accommodated in the sealing installation groove 311, one side of the sealing ring 32 and the positioning protrusions 313 abut against each other, and the positioning protrusions 313 squeeze one side of the sealing ring 32. Therefore, the setting of the positioning protrusions 313 can limit the position of the sealing ring 32 to a certain extent, thereby avoiding lifting the sealing ring 32 during the opening and closing process of the base 10 and the upper cover 20.

[0027] The shape and size of the sealing ring 32 are matched with the shape and size of the sealing installation groove 311, and when in use, the sealing ring 32 is accommodated in the sealing installation groove 311. The sealing ring 32 can be made of a soft dustproof and anti-static material such as rubber. The sealing ring 32 itself is a prior art and will not be described in detail here.

[0028] The upper cover sealing rib 33 is fixedly arranged in the bottom plate mounting groove 22 and faces one end of the bottom plate 11, and the upper cover sealing rib 33 is arranged corresponding to the sealing ring 32. When the base 10 and the upper cover 20 are closed, one end of the upper cover sealing rib 33 is inserted into the sealing mounting groove 311 and abuts against the sealing ring 32 to form a sealing structure. The cross-sectional outer contour of the sealing ring 32 is in an inverted U shape. During the assembly process, one side of the free end of the upper cover sealing rib 33 abuts against one side of the sealing ring 32 and presses down. And because the cross-sectional outer contour of the sealing ring 32 is in an inverted U shape, the center position of the sealing ring 32 drops under the abutment of the upper cover sealing rib 33, so that the two sides of the sealing ring 32 are covered on the two side walls of the upper cover sealing rib 33, thereby improving the sealing between the sealing ring 32 and the upper cover sealing rib 33. Preferably, one side of the free end of the upper cover sealing rib 33 is arranged in a V shape, so as to facilitate the detachment of the base 10 and the upper cover 20 and the separation of the sealing ring 32 and the upper cover sealing rib 33 .

[0029] Compared with the prior art, the present invention provides a mask plate transport box capable of preventing the sealing ring from overflowing, comprising a base 10, an upper cover 20 arranged on one side of the base 10, and a sealing assembly 30 arranged between the base 10 and the upper cover 20. The sealing assembly 30 comprises a sealing installation unit 31 fixedly arranged on the base 10, a sealing ring 32 accommodated in the sealing installation unit 31, and an upper cover sealing rib 33 fixedly arranged on the upper cover 20. The sealing installation unit 31 comprises a sealing installation groove 311 arranged along the periphery of the base 10, a limiting baffle 312 arranged along the outer contour of the sealing installation groove 311, and a plurality of positioning protrusions 313 arranged on the side wall of the base 10 along the outer contour of the base 10. When the sealing ring 32 is accommodated in the sealing installation groove 311, the positioning protrusions 313 squeeze the sealing ring 32, so that the position of the sealing ring 32 in the sealing installation groove 311 remains relatively stable. When the base 10 and the upper cover 20 are closed, one end of the upper cover sealing rib 33 is inserted into the sealing installation groove 311 and abuts against the sealing ring 32 to form a sealing structure. Furthermore, the mask plate transport box that can prevent the sealing ring from overflowing is further provided with the limiting baffle 312 on the outer side of the sealing installation groove 311, so that when the base 10 and the upper cover 20 are closed, the limiting baffle 312 can effectively prevent the sealing ring 32 from overflowing.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention.
