The seal box with a good sealing effect and easy to open comprises a box body 1 and a sealing cover 2, wherein the box body 1 is formed with an opening 101, a sealing mechanism 3 is disposed between the opening 101 of the box body 1 and the sealing cover 2, the sealing cover 2 is detachably mounted at the opening 101 of the box body 1, and the sealing mechanism 3 is in a locked and sealed state.

(12) The sealing mechanism 3 comprises a female sealing unit 301 and a male sealing unit 302, wherein the male sealing unit 302 is disposed at the opening 101 of the box body 1, and the female sealing unit 301 is disposed on a bottom surface of the sealing cover 2.

(13) The male sealing unit 302 comprises a circular sealing edge 3021 and a buckle 3022, wherein the circular sealing edge 3021 is fixed to the opening 101 of the box body 1 (in this embodiment, the circular sealing edge 3021 and the box body 1 are integrally formed), and the buckle 3022 is disposed on an outer wall of the circular sealing edge 3021.

(14) The female sealing unit 301 comprises a circular sealing slot 3011 and a clamping groove 3012 allowing the buckle 3022 to be clamped therein, wherein the circular sealing slot 3011 is fixed to the bottom surface of the sealing cover 2 (in this embodiment, the circular sealing slot 3011 and the sealing cover 2 are integrally formed), and the clamping groove 3012 is formed in an inner wall of the circular sealing slot 3011. When placed at the opening 101 of the box body 1, the sealing cover 2 is pressed downwards to force the circular sealing edge 3021 to be inserted into the circular sealing slot 3011 in the bottom surface of the sealing cover 2, the buckle 3022 is clamped in the clamping groove 3012, and the sealing cover 2 completely seals the opening 101 in the top end of the box body 1.

(15) A quick opening mechanism 4 is further disposed between the box body 1 and the sealing cover 2 and comprises an opening base 401 and an opening element 402, wherein the opening base 401 is disposed at the top of an outer wall of the box body 1, two ends of the opening element 402 are an opening end 4021 and an operating end 4022 respectively, the middle (closer to the opening end 4021) of the opening element 402 is rotatably mounted on the edge of the sealing cover 2 (the edge of the sealing cover 2 is provided with two hinge seats 201 formed with hinge holes 2011, and two hinge shafts 4023 are disposed in the middle of the opening element 402 and are inserted into the hinge holes 2011 of the two hinge seats 201 respectively), the opening end 4021 is located on a top surface of the opening base 401, and the operating end 4022 is away from the top surface of the opening base 401. When the sealing cover 2 is to be opened, users pull the operating end 4022 to enable the operating end 4022 to rotate, and then the opening end 4021 presses against the top surface of the opening base 401 to force two parts, between the area where the opening end 4021 is located of the sealing cover 2 and the opening 101 of the box body 1, of the sealing mechanism 3 to be separated, so that the uses can perform further operations to open the sealing cover 2. Because the users cannot operate the sealing mechanism 3 when the sealing mechanism 3 is in the locked and sealed state, the quick opening mechanism 4 is configured to unlock the sealing mechanism 3 at a certain position to separate the parts of the sealing mechanism 3 at this position, so that the users can perform further operations at this position to completely unlock the sealing mechanism 3, and then the sealing cover 2 is completely disassembled. Based on the lever principle, the quick opening mechanism 4 simplifies the operations and destroys the locked and sealed state of the sealing cover 2 to allow the sealing cover 2 to be opened easily, quickly and effortlessly.

(16) The opening element 402 is shaped like a straight plate, the opening end 4021 of the opening element 402 protrudes downwards, and a bottom surface of the operating end 4022 of the opening element 402 is close to a top surface of the sealing cover 2. In this embodiment, to make the overall appearance of the seal box more uniform, an opening element accommodating groove 202 which is concaved downwards is specially designed in the top surface of the sealing cover 2, and the opening element 402 is located in the opening element accommodating groove 202 in a non-open state. In this way, the opening element 402 can be supported by the top surface of the sealing cover 2, thus being prevented from shaking and being easy to store and carry.

(17) A curved surface 40211 in smooth transition is disposed on an outer side of the opening end 4021 of the opening element 402. The curved surface 40211 in smooth transition can effectively protect the opening end 4021 against damage when the opening end 3021 contacts with the top surface of the opening base 401.

(18) An oblique surface 40221 which inclines upwards is disposed at the bottom of the operating end 4022 of the opening element 402. Users can easily insert their fingers into a gap between the operating end 4022 of the opening element 402 and the top surface of the sealing cover 2 through the oblique surface 40221 to pull the operating end 4022 of the opening element 402 upwards.

(19) The operating process is introduced below in conjunction with FIG. 1-FIG. 5:

(20) When the seal box needs to be sealed, users place the sealing cover 2 over the opening 101 in the top end of the box body 1 and presses the sealing cover 2 downwards to force the circular sealing edge 3021 at the opening 101 in the top end of the box body 1 to be inserted into the circular sealing slot 3011 in the bottom surface of the sealing cover 2, and the buckle 3022 is clamped in the clamping groove 3012, so that the sealing cover 2 can completely seal the opening 101 in the top end of the box body 1.

(21) When the seal box needs to be opened, users insert their fingers of one hand into the gap between the operating end 4022 of the opening element 402 and the top surface of the sealing cover 2 and then lift the operating end 4022 of the opening element 402 to enable the opening element 402 to rotate, and the opening end 4021 of the opening element 402 moves downwards, abuts against the top surface of the opening base 401 and then forces the area, where the opening element 402 is located, of the sealing cover 2 to move upwards to force the circular sealing slot 3011 to be separated from the circular sealing edge 3021, so that the sealing cover 2 is opened.

(22) Tests prove that the seal box in this embodiment has an extremely good actual use effect and can be opened by users with a single hand easily, quickly and effortlessly.

Embodiment 2

(23) As shown in FIG. 6-FIG. 8, the seal box with a good sealing effect and easy to open in this embodiment differs from the seal box in Embodiment 1 in the following aspects:

(24) The opening element 402 is shaped like 7, the opening element 402 comprises an operating section 4025 extending vertically and an opening section 4024 extending horizontally, a corner of the opening element 402 is rotatably mounted on the edge of the sealing cover 2, the operating end 4022 of the opening element 402 is located at a bottom end of the operating section 4025, and the opening end 4021 of the opening element 402 is located at a tail end of the opening section 4024

(25) The opening end 4021 of the opening element 402 is semi-cylindrical. By designing the opening end 4021 to be semi-cylindrical, the sliding friction between the opening end 4021 and the top surface of the opening base 401 makes operation smoother when the opening end 4021 presses against the top surface of the opening base 401, and the opening end 4021 is less likely to be damaged.

(26) The opening end 4021 is formed with a plurality of grooves 40211, so that materials can be effectively saved.

(27) A locking piece 40251 for locking the bottom surface of the opening base 401 is disposed on an inner wall of the operating section 4025. When the operating section 4025 is vertically downwards and is in a non-open state, the locking piece 40251 locks the bottom surface of the opening base 401, so that the opening element 402 is prevented from shaking and is easy to store and carry.

(28) The operating process is very simple. Users just need to pull the operating end 4022 to enable the opening element 402 to rotate to force the opening end 4021 to press against the top surface of the opening base 401, and then the area, where the opening element 402 is located, of the sealing cover 2 is forced to move upwards to force the circular sealing slot 3011 to be separated from the circular sealing edge 3021, so that the sealing cover 2 is opened.

Embodiment 3

(29) As shown in FIG. 9 and FIG. 10, the seal box with a good sealing effect and easy to open in this embodiment differs from the seal box in Embodiment 1 in the following aspects:

(30) The circular sealing slot 3011 of the female sealing unit 301 comprises an outer slot plate 30111 and an inner slot plate 30112, the clamping groove 3012 is formed in an inner wall of the outer slot plate 30111, and a curved sealing surface 3013 capable of abutting and pressing against an inner wall of the buckle 3022 is disposed on an inner wall of the inner slot plate 30112. When the sealing cover 2 is placed at the opening 101 of the box body 1, the sealing cover 2 is pressed downwards to force the circular sealing edge 3021 to be inserted into the circular sealing slot 3011 in the bottom surface of the sealing cover 2, the buckle 3022 is clamped in the clamping groove 3012, and at this moment, the curved sealing surface 3013 abuts and presses against the inner wall of the buckle 3022, so that the sealing effect of the sealing cover 2 is better. Tests prove that good sealing performance can be guaranteed even if the seal box is inclined, inverted or shaken.

(31) FIG. 9 is a horizontal sectional view in which the quick opening mechanism 4 cannot be seen.
