DETAILED DESCRIPTION

[0035] The present invention is further described below in conjunction with the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Figure 1 1 is an overall schematic diagram of a cigarette box 10 according to an embodiment of the present invention. The cigarette box 10 contains tobacco leaves to be processed, and the cigarette box 10 is made of hard material. The cigarette box 10 is used to contain tobacco leaves, and the cigarette box 10 is provided with a locking mechanism 20, which can lock the cigarette box 10 during transportation, and the transportation bumps will not cause damage to the cigarette box 10. When the tobacco leaves are stored in the warehouse, they can be neatly stacked, paving the way for the realization of intelligent production in the subsequent processing flow.

[0037] Please also refer to Figure 2 , Figure 3 and Figure 4 The locking mechanism 20 includes a clamping plate 210 , a first matching piece 220 and a second matching piece 230 .

[0038] The clamping plate 210 is disposed at one side of the locking mechanism 20 , and a clamping buckle 211 is provided on the clamping plate 210 .

[0039] A rotation slot 221 is formed at one end of the first matching piece 220, and a slot 222 is formed at the other end to match the buckle 211. The end of the buckle 211 is designed to be arc-shaped, and the arc-shaped end matches the slot 222. The arc-shaped end is inserted into the slot 222 to match and connect. The buckle 211 is elastically connected to the body of the card plate, such as Figure 3 As shown, the buckle 211 is integrally arranged with the body of the card board, that is, a U-shaped groove is opened on the card board body to form the buckle 211. Under the action of external force, the buckle 211 can be separated from the card slot 222.

[0040] The two sides of the slot 222 of the first matching piece 220 are provided with grooves 223 for engaging the part to be fixed. In the present invention, the part to be fixed is the body of the cigarette box 10, and the grooves 223 and the limiting grooves 111 ( Figure 4 as shown) with fixed fit (see below for details).

[0041] The second matching member 230 has an operating shaft 231 on one side and an eccentric shaft 232 on the other side. The eccentric shaft 232 moves in coordination with the rotating groove 221. The rotating groove 221 includes a first rotating groove 2211 and a second rotating groove 2212. The first rotating groove 2211 and the second rotating groove 2212 are connected and are arranged in parallel.

[0042] The clamping slot 222 includes a sliding slot 2221 and two positioning slots 2222 , wherein the sliding slot 2221 is arranged along the moving direction of the first matching member 220 ; each positioning slot 2222 is arranged perpendicular to the sliding slot 2221 . The two positioning slots 2222 are arranged perpendicular to the sliding slot 2221 , respectively.

[0043] The operating shaft 231 is located at the edge of the second matching piece 230 , and the operating shaft 231 matches with the sliding groove 2221 .

[0044] like Figure 4 As shown, during the opening process of the lock mechanism 20, an external force (i.e., the first key) is first used to press the arc-shaped end of the buckle 211, and the arc-shaped end moves out of the slot 222, thereby separating the buckle 211 from the slot 222. At this time, the position of the first matching member 220 remains unchanged. Then, the operating shaft 231 is rotated by using the rotating member (i.e., the second key), and the rotation of the operating shaft 231 drives the eccentric shaft 232 of the second matching member 230 to rotate in the rotating slot 221. The eccentric shaft 232 moves from the first rotating slot 2211 to the second rotating slot 2212. When the first matching member 220 does not have the buckle 211 to cooperate with the slot 222, the eccentric shaft 232 pushes the first matching member 220 to move upward, so that the groove 223 is separated from the limiting slot 111 on the box body, thereby opening the hard cigarette box 10.

[0045] The present invention also provides a cigarette box 10 with a locking mechanism 20, comprising a cigarette box body 110 and a cover plate 120. Figure 5 As shown, the cover plate 120 is provided with a first receiving groove 121, a second receiving groove 122 and a third receiving groove 123 from the inside to the outside in sequence; the second matching piece 230 is placed in the first receiving groove 121; the first matching piece 220 is placed in the second receiving groove 122; and the clamping plate 210 is placed in the third receiving groove 123.

[0046] Please also refer to Figure 3 , Figure 4 and Figure 5 The edge of the cigarette box body 110 is provided with a limiting groove 111, which is fixedly matched with the groove 223 of the first matching piece 220. The cover plate 120 is provided with a first operating hole 124 and a second operating hole 125. The first operating hole 124 is arranged corresponding to the movable end of the buckle 211. The first key passes through the first operating hole 124 to apply an external force to the buckle 211, so that the buckle 211 is separated from the slot 222. The second operating hole 125 is arranged corresponding to the operating shaft 231, and the second key cooperates with the operating shaft 231 through the second operating hole 125. At this time, the buckle 211 and the slot 222, the buckle 211 cannot limit the position of the slot 222, and the rotating operating shaft 231 drives the eccentric shaft 232 to move from the first rotating slot 2211 to the second rotating slot 2212. The eccentric shaft 232 moves upward against the first matching piece 220, so that the groove 223 is separated from the limiting slot 111 on the box body, completing the opening action of the lock mechanism 20.

[0047] The locking mechanism 20 provided by the present invention and the cigarette box 10 using the same, utilize the first matching piece 220 and the second matching piece 230 to play a double locking role. The cigarette box 10 will not be damaged due to bumps during transportation; further, the cigarette box 10 is used to prevent the tobacco leaves after transportation from entering impurities such as sack lines, thereby affecting the purity of the tobacco leaves in the next step of processing. When the tobacco leaves are stored in the warehouse, they can be neatly stacked, paving the way for the subsequent processing flow to realize intelligent production. Finally, using the cigarette box 10 with the locking mechanism 20, the entire process is easy to transport and the cigarette box 10 can be reused.

[0048] At this point, those skilled in the art should recognize that, although multiple exemplary embodiments of the present invention have been shown and described in detail herein, many other variations or modifications that conform to the principles of the present invention can still be directly determined or derived based on the content disclosed in the present invention without departing from the spirit and scope of the present invention. Therefore, the scope of the present invention should be understood and recognized as covering all these other variations or modifications.
