[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 5 As shown, it is a schematic diagram of the structure of a mask plate transport box that can automatically maintain a closed state provided by the utility model. The mask plate transport box that can automatically maintain a closed state includes a box body 10, and a plurality of locking mechanisms 20 arranged on the box body 10 for fixing the box body 10. It is conceivable that the mask plate transport box that can automatically maintain a closed state should also include some other functional components, such as installation components, connection components, etc., which are all prior arts known to those skilled in the art and will not be elaborated here.

[0020] The box body 10 includes a bottom plate 11 and an upper cover 12 disposed on one side of the bottom plate 11 .

[0021] The bottom plate 11 includes a plate body 111 , at least two support frames 112 respectively arranged on one side of the plate body 111 facing the upper cover 12 , two limit clamps 113 arranged on one side of the plate body 111 , and at least two plug holes 114 symmetrically arranged on both sides of the plate body 111 .

[0022] The plate body 111 may be a square structure. It is understandable that the plate body 111 may also be provided with a plurality of screw holes for connection and other functional components such as fasteners, which are prior arts known to those skilled in the art and will not be described in detail here.

[0023] At least two support frames 112 are arranged on the plate body 111. The support frames 112 are symmetrically arranged on opposite sides of the plate body 111 along the edge of the plate body 111. In this embodiment, four support frames 112 are arranged. The support frames 112 are used to support the mask plate so as to mount the mask plate on the plate body 111.

[0024] The limiting clamp 113 is fixedly disposed on one side edge of the plate body 111 to limit the mask plate mounted on the support frame 112, thereby preventing the mask plate from moving and being damaged during transportation.

[0025] The direction in which the support frame 112 is arranged on the plate body 111 is perpendicular to the direction in which the position-limiting clamp 113 is arranged. Thus, the support frame 112 and the position-limiting clamp 113 can position the mask plate transported by the mask plate transport box from two mutually perpendicular directions to ensure the stability of the mask plate. The support frame 112 and the position-limiting clamp 113 are both prior art and will not be described in detail here.

[0026] The plug holes 114 are symmetrically arranged on both sides of the plate body 111, and the arrangement direction of the plug holes 114 is parallel to the arrangement direction of the limit clamp 113. The plug holes 114 are used to arrange the locking mechanism 20, so they will be described in detail below in conjunction with the locking mechanism 20.

[0027] The upper cover 12 is fixedly connected to the bottom plate 11 through the locking mechanism 20 to protect the optical mask plate contained in the transport box. The upper cover 12 includes an upper cover body, a bottom plate mounting groove 121 arranged on the side of the upper cover body facing the bottom plate 11, a locking mounting groove 122 arranged outside the bottom plate mounting groove 121, a plurality of locking mechanism positioning cards 123 arranged in the locking mounting groove 122, and a plurality of sliding avoidance openings 124 arranged on the side wall of the locking mounting groove 122 corresponding to the locking mechanism positioning cards 123.

[0028] The inner contour of the bottom plate installation groove 121 is matched with the outer contour of the bottom plate 11. When the mask plate transport box is closed, the bottom plate 11 is accommodated in the bottom plate installation groove 121.

[0029] The locking groove 122 is arranged in a U-shape along the edge of the outer contour of the bottom plate mounting groove 121 , that is, the inner contour of the locking groove 122 is consistent with the outer contour of the bottom plate mounting groove 121 . The locking groove 122 is used to accommodate the locking mechanism 20 .

[0030] The locking mechanism positioning card 123 is used to fix the locking mechanism 20. The locking mechanism positioning card 123 includes a positioning card body 1231 fixedly connected to the locking installation slot 122, and a positioning port 1232 arranged on the positioning card body 1231 close to the side opposite to the bottom plate 11. The positioning card body 1231 is a square card, and its three sides are fixedly connected to the side walls of the locking installation slot 122. The positioning port 1232 can be a square port, and matches with the corresponding structure of the locking mechanism 20 to fix the locking mechanism 20 to the upper cover 12.

[0031] The size of the sliding avoidance opening 124 is matched with the size of the locking mechanism 20 , and the position of the sliding avoidance opening 124 corresponds to the position of the plug-in hole 114 , so that the locking mechanism 20 can be slidably released.

[0032] Each of the locking mechanisms 20 includes a fixing block 21 received in the locking installation slot 122 , and a locking unit 22 slidably connected to the fixing block 21 .

[0033] Each of the fixing blocks 21 includes a fixing block body 211 , a locking sliding groove 212 disposed on a side of the fixing block body 211 facing the bottom plate 11 , and two connecting hooks 213 disposed on both side ends of the fixing block body 211 .

[0034] When the fixing block 21 is installed in the locking installation slot 122 , the fixing slider body 211 is matched and connected with the locking mechanism positioning card 123 through the connecting hook 213 it has, so as to be fixedly connected in the locking installation slot 122 .

[0035] The locking sliding groove 212 is arranged on a side of the fixing block body 211 facing the bottom plate 11. The locking sliding groove 212 is used to accommodate the locking unit 22, and the locking sliding groove 212 is arranged in a T-shape, so as to better limit the position of the locking unit 22, thereby preventing the locking unit 22 from being displaced in a non-sliding direction.

[0036] The connecting hook 213 includes a hook body 2131 and a positioning protrusion 2132 disposed at one end of the hook body 2131. When the fixed connecting hook 213 is connected to the locking mechanism positioning card 123, the positioning protrusion 2132 is inserted into the positioning opening 1232 of the locking mechanism positioning card 123, thereby fixing the fixing block 213 in the locking installation slot 122.

[0037] The locking unit 22 includes a sliding block 221 slidably connected to the locking sliding groove 212, an elastic member limiting plate 222 arranged on the sliding block 221, at least two elastic members 223 respectively arranged at both ends of the elastic member limiting plate 222, a locking pin hole 224 arranged on the sliding block 221, a locking pin 225 for being inserted into the locking pin hole 224, and a locking tongue 226 arranged on one side of the sliding block 221.

[0038] The sliding block 221 is a T-shaped structure corresponding to the locking sliding groove 212. The sliding block 221 is accommodated in the locking sliding groove 212 and forms a sliding connection with the locking sliding groove 212.

[0039] The elastic member limiting plate 222 is fixedly connected to the edge of the side of the sliding block 221 opposite to the bottom plate 11. The elastic member limiting plate 222 includes a limiting plate body 2221, and at least two elastic member receiving holes 2222 fixedly arranged at both ends of the limiting plate body 2221. The limiting plate body 2221 is arranged at the edge of the sliding block 221 along the length direction of the sliding block 221. The limiting plate body 2221 can be a square plate body with the same length as the sliding block 221. The elastic member receiving hole 2222 is arranged on the side of the limiting plate body 2221 facing the fixed block 21. The elastic member receiving hole 2222 is used to accommodate the elastic member 223 for limiting, so the number of the elastic member 223 is the same as the number of the elastic member 223 and is a circular hole arranged to match the elastic member 223.

[0040] One end of the elastic member 223 is fixedly inserted in the elastic member receiving hole 222, and the other end is in contact with the fixing block body 211. The elastic member 223 may be a spring. When the mask plate transport box does not need to be opened, the locking tongue 226 is in contact with the insertion hole 114 of the bottom plate 11 under the elastic force of the elastic member 223, so that the bottom plate 11 and the upper cover 12 are locked to form a closed state.

[0041] The pin locking hole 224 is centrally disposed on the sliding block 221 and extends from a side of the sliding block 221 facing the bottom plate 11 to a side of the sliding block 221 facing away from the bottom plate 11 .

[0042] The locking pin 225 is arranged to match the size of the locking pin hole 224. It is conceivable that the locking pin 225 is fixedly arranged on a fixed surface such as a workbench or a machine table.

[0043] The locking tongue 226 is fixedly arranged on the side of the sliding block 221 opposite to the elastic member 223. One end of the locking tongue 226 is fixedly connected to the sliding block 221, and the other end is inserted into the plug hole 114, so that the bottom plate 11 and the upper cover 12 are in a closed state. When it is necessary to open the mask plate transport box, the locking pin 225 is inserted into the locking pin hole 224, and the sliding block 221 is moved toward the side opposite to the plug hole 114, thereby compressing the elastic member 223 so that the locking tongue 226 moves out of the plug hole 112, and the bottom plate 11 can fall off on the workbench under the action of gravity, completing the opening action.

[0044] The bottom plate 11 of the mask plate transport box is connected to the upper cover 12 via the locking mechanism 20. The locking mechanism includes a fixed block 21 fixedly engaged with the upper cover 12, and a locking unit 22 slidably connected with the fixed block 21. When the box body 10 is closed, the elastic member 223 of the locking unit 22 pushes the locking tongue 226 against the plug-in hole 112, thereby closing the bottom plate 11 and the upper cover 12 together. When the box body 10 needs to be opened, the locking pin 225 is inserted into the locking pin hole 224, and the sliding block 221 is moved to slide along the extension of the plug-in hole 114 to compress the elastic member 223, thereby moving the locking tongue 226 out of the plug-in hole 112 to complete the opening action. When the locking pin 225 is pulled out of the locking pin hole 224, the locking tongue 226 is inserted into the plug hole 114 again under the elastic force of the elastic member 223, so that the bottom plate 11 and the upper cover 12 are restored to the closed state. Therefore, when the mask plate transport box is not in use, the box body 10 can also automatically maintain a closed state.

[0045] Compared with the prior art, the utility model provides a mask plate transport box capable of automatically maintaining a closed state, comprising a box body 10 and a locking mechanism 20 disposed on the box body 10. The box body comprises a bottom plate 11 and an upper cover 12 disposed on one side of the bottom plate 11. The bottom plate 11 comprises a plate body 111, at least two support frames 112 respectively disposed on one side of the plate body 111 facing the upper cover 12, two limit clamps 113 disposed on one side of the plate body 111, and at least two plug-in holes 114 respectively disposed on opposite sides of the plate body 111. The locking mechanism 20 comprises at least two fixing blocks 21, and at least two locking units 22 slidably connected to the fixing blocks 21. The locking unit 22 includes a sliding block 221, an elastic member limiting plate 222 disposed on the sliding block 221, at least two elastic members 223 disposed at both ends of the elastic member limiting plate 222, a locking pin hole 224 disposed on the sliding block 221, a locking pin 225 disposed corresponding to the locking pin hole 224, and a locking tongue 226 disposed on one side of the sliding block 221. The sliding block 221 is slidably connected to the fixed block 21, one end of the elastic member 223 is fixedly connected to the sliding block 221, and the other end abuts against the fixed block 21. Under the elastic force of the elastic member 223, one end of the locking tongue 226 is inserted into the insertion hole 114 to close the bottom plate 11 and the upper cover 12 together. When the box body 10 needs to be opened, the locking pin 225 is inserted into the locking pin hole 224, and the sliding block 221 is moved to compress the elastic member 223, and the locking tongue 226 is moved out of the plug hole 112 to complete the opening action. And under the elastic rebound force of the elastic member 223, when the box body 10 is not in use, the box body 10 can also automatically remain in a closed state. Therefore, the mask plate transport box can automatically remain in a closed state when not in use, thereby isolating air pollution and maintaining a high clean state.
