[0021] First embodiment, such as Figures 1 to 14As shown, a clamping device for sealing the opening of a transparent bag body 60 includes a first clamping plate 10, a second clamping plate 20, and at least one locking member 30. The first clamping plate 10 has a first locking groove 11, and the second clamping plate 20 has a second locking groove 21. The locking member 30 includes a rotating arm 31, a first pressing plate 32, and a second pressing plate 33. The first pressing plate 32 and the second pressing plate 33 are respectively disposed on the two side walls of the rotating arm 31. When the first clamping plate 10 and the second clamping plate 20 are closed, a storage groove 40 is formed between the first clamping plate 10 and the second clamping plate 20. The groove 40 is provided with a locking groove 41, and the rotating end of the rotating arm 31 is rotatably connected to the inner wall of the storage groove 40. When the rotating arm 31 rotates into the storage groove 40, the first pressing plate 32 and the second pressing plate 33 clamp the first locking groove 11 and the second locking groove 21. When the rotating arm 31 is removed from the storage groove 40, the first pressing plate 32 and the second pressing plate 33 release the first locking groove 11 and the second locking groove 21. The free end of the rotating arm 31 is provided with a locking buckle 36 on the side near the rotating end. The locking buckle 36 can be inserted into or removed from the locking groove 41 as the rotating arm 31 rotates.

[0022] like Figures 1 to 14 As shown, the first clamping plate 10 and the second clamping plate 20 are closed. The rotating arm 31 rotates around the storage groove 40 in one direction. When the first pressing plate 32 is clamped in the first locking groove 11 and the second pressing plate 33 is clamped in the second locking groove 21, the locking member 30 presses the first clamping plate 10 and the second clamping plate 20, so that the first clamping plate 10 and the second clamping plate 20 are locked together, thereby sealing the opening of the transparent bag body 60. At the same time, the locking buckle 36 is inserted into the locking groove 41 as the rotating arm 31 rotates, preventing the rotating arm 31 from rotating freely, and the locking effect is good. When the rotating arm 31 rotates in another direction, the locking buckle 36 disengages from the locking groove 41 as the rotating arm 31 rotates. At this time, the first pressing plate 32 disengages from the first locking groove 11 and the second pressing plate 33 disengages from the second locking groove 21. Under the action of external force, the first clamping plate 10 and the second clamping plate 20 move away from each other, thereby opening the opening of the transparent bag body 60, making it easy to take out the contained items, such as mobile phones and other electronic products.

[0023] Second embodiment, such as Figures 3 to 14As shown, the first locking groove 11 includes a first outer opening groove 111 and a first inner opening groove 112. The diameter of the first outer opening groove 111 is larger than that of the first inner opening groove 112. The first inner opening groove 112 is located on the side near the second clamping plate 20. The first pressing plate 32 is connected to one side wall of the rotating arm 31 through the first connecting part 34. The second locking groove 21 includes a second outer opening groove 211 and a second inner opening groove 212. The diameter of the second outer opening groove 211 is larger than that of the second inner opening groove 212. The second inner opening groove 212 is located on the side near the first clamping plate 10. The second pressing plate 33 is connected to the other side wall of the rotating arm 31 through the second connecting part 35. When the rotating arm 31 rotates into the storage groove 40, the first connecting part 34 is inserted into the first inner opening groove 112, the first pressing plate 32 is pressed into the first outer opening groove 111, the second connecting part 35 is inserted into the second inner opening groove 212, and the second pressing plate 33 is pressed into the second outer opening groove 211.

[0024] like Figures 3 to 14 As shown, the first outer opening groove 111 is located on the side away from the second clamping plate 20, and the first inner opening groove 112 is close to the second clamping plate 20. When the rotating arm 31 rotates into the storage groove 40, the first connecting part 34 is inserted into the first inner opening groove 112, and the first pressing plate 32 is pressed into the first outer opening groove 111, making the locking more secure and preventing the first clamping plate 10 and the second clamping plate 20 from moving relative to each other. The second outer opening groove 211 is located on the side away from the first clamping plate 10, and the second outer opening groove 211 is close to the first clamping plate 10. The second connecting part 35 is inserted into the second inner opening groove 212, and the second pressing plate 33 is pressed into the second outer opening groove 211, making the locking more secure and preventing the first clamping plate 10 and the second clamping plate 20 from moving relative to each other.

[0025] like Figures 3 to 14 As shown, the side of the first inner opening groove 112 closest to the first outer opening groove 111 is its upper surface. The upper surface of the first inner opening groove 112 is an inclined surface, and the thickness of the upper surface of the first inner opening groove 112 near the opening is less than the thickness away from the opening. The side of the second inner opening groove 212 closest to the second outer opening groove 211 is its upper surface. The upper surface of the second inner opening groove 212 is an inclined surface, and the thickness of the upper surface of the second inner opening groove 212 near the opening is less than the thickness away from the opening. When the rotating arm 31 rotates in one direction into the receiving groove 40, the first pressing plate 32 presses against the upper surface of the first inner opening groove 112, and the first pressing plate 32 presses harder and harder. The second pressing plate 33 presses against the upper surface of the second inner opening groove 212, locking the slope. The second pressing plate 33 presses harder and harder, resulting in a good sealing effect.

[0026] like Figures 1 to 13As shown, there are two first locking slots 11, located at both ends of the first clamping plate 10. Similarly, there are two second locking slots 21, located at both ends of the second clamping plate 20. When the first clamping plate 10 and the second clamping plate 20 are closed, the first locking slot 11 and the corresponding second locking slot 21 are parallel to each other. Both the first and second locking slots 11 and 21 have U-shaped openings. When the rotating arm 31 is rotated, the first pressing plate 32 is inserted into the first locking slot 11 from the upper end of the first clamping plate 10, and the second pressing plate 33 is inserted into the second locking slot 21 from the upper end of the second clamping plate 20, resulting in a more secure lock.

[0027] like Figures 1 to 13 As shown, the first locking groove 11 and the second locking groove 21 are aligned, and the first locking groove 11 and the second locking groove 21 have the same structure. The first pressing plate 32 and the second pressing plate 33 are symmetrically arranged on both sides of the rotating arm 31.

[0028] like Figures 1 to 13 As shown, there are two locking elements 30. After the first clamping plate 10 and the second clamping plate 20 are closed, two receiving slots 40 are formed between the first clamping plate 10 and the second clamping plate 20. The two receiving slots 40 are located at both ends of the first clamping plate 10, and each receiving slot 40 contains a locking element 30. The two locking elements 30 simultaneously lock the first clamping plate 10 and the second clamping plate 20.

[0029] The third embodiment, such as Figures 3 to 13 As shown, the rotating end of the rotating arm 31 is rotatably connected to the inner wall of the first clamping plate 10 through the first rotating shaft 51, and the inner wall of the second clamping plate 20 is provided with the second rotating shaft 52. When the first clamping plate 10 and the second clamping plate 20 are closed, the first rotating shaft 51 and the second rotating shaft 52 are inserted into each other.

[0030] like Figures 3 to 13 As shown, the first clamping plate 10 and the second clamping plate 20 are closed, and the first rotating shaft 51 and the second rotating shaft 52 are inserted into each other. Rotating the rotating arm 31 in one direction causes the first pressing plate 32 to be clamped in the first locking groove 11 and the second pressing plate 33 to be clamped in the second locking groove 21. The locking member 30 locks the first clamping plate 10 and the second clamping plate 20. The first clamping plate 10 and the second clamping plate 20 are locked together to achieve a seal on the opening of the transparent bag body 60. Rotating the rotating arm 31 in another direction causes the first pressing plate 32 to disengage from the first locking groove 11 and the second pressing plate 33 to disengage from the second locking groove 21. Under the action of external force, the first clamping plate 10 and the second clamping plate 20 move away from each other, and the first rotating shaft 51 and the second rotating shaft 52 disengage from each other, so that the opening of the transparent bag body 60 can be opened to facilitate the removal of the contained items, such as mobile phones and other electronic products.

[0031] like Figures 3 to 13As shown, the first rotating shaft 51 has a cross-shaped elastic groove 511 along its axial direction, and the second rotating shaft 52 has a crosshead 521 along its axial direction. When the first clamping plate 10 and the second clamping plate 20 are closed, the crosshead 521 is inserted into the cross-shaped elastic groove 511. After the first clamping plate 10 and the second clamping plate 20 are closed, the first rotating shaft 51 and the second rotating shaft 52 are firmly connected.

[0032] Fourth embodiment, such as Figures 3 to 13 As shown, the first clamping plate 10 has several positioning posts 12 on the side near the second clamping plate 20, and the second clamping plate 20 has several positioning holes 22 on the side near the first clamping plate 10. When the first clamping plate 10 and the second clamping plate 20 are closed, the positioning posts 12 are inserted into the positioning holes 22. After the locking member 30 locks the first clamping plate 10 and the second clamping plate 20, the positioning posts 12 are inserted into the positioning holes 22 to prevent the first clamping plate 10 and the second clamping plate 20 from shaking, so that the first clamping plate 10 and the second clamping plate 20 are clamped more tightly.

[0033] like Figures 3 to 13 As shown, the free end of the rotating arm 31 is provided with a push part 37, and the storage groove 40 is located at the end of the first clamping plate 10 and the second clamping plate 20. When the rotating arm 31 rotates into the storage groove 40, the push part 37 of the rotating arm 31 extends out of the storage groove 40. When in use, by turning the push part 37 of the rotating arm 31, the rotating arm 31 can quickly rotate within the storage groove 40, facilitating locking and unlocking.

[0034] like Figures 3 to 13 As shown, the second clamping plate 20 has a triangular waterproof protrusion 23 on the side near the first clamping plate 10, and the first clamping plate 10 has a triangular waterproof groove 13 on the side near the second clamping plate 20 for cooperating with the triangular waterproof protrusion 23 to press the opening of the transparent bag body 60. The second clamping plate 20 has a triangular waterproof protrusion 23 along its length, and the first clamping plate 10 has a triangular waterproof groove 13 along its length. When the first clamping plate 10 and the second clamping plate 20 are closed, and the locking member 30 locks the first clamping plate 10 and the second clamping plate 20 closed, the triangular waterproof protrusion 23, the opening of the transparent bag body 60 and the triangular waterproof groove 13 are pressed together in sequence, which can further improve the sealing performance of the transparent bag body 60.

[0035] like Figures 3 to 13 As shown, the locking buckle 36 has a hook-shaped structure, and the storage groove 40 is provided with an inclined plate 42, forming a locking groove 41 between the inclined plate 42 and the storage groove 40.

[0036] Fifth embodiment, such as Figures 1 to 14As shown, a waterproof bag includes the aforementioned clamping device and a transparent bag body 60, with the clamping device disposed at the opening of the transparent bag body 60.

[0037] The above are specific embodiments of this utility model.
