[0034] The top of the lower pressing block 7 is fixed to the front end or rear end on the right side of the bottom of the box door 2. When the box door 2 is closed, the bottom of the lower pressing block 7 contacts the top of the tooth plate 12 and will not contact the right inner wall of the box body 1. The first spring rod 8 can drive the limiting ball 10 at the bottom of the fixed block 9 to extend and retract, so that the limiting ball 10 can limit the inclined block 15.

[0035] The second spring rod 11 is fixedly connected to the bottom of the inner cavity of the box body 1; wherein, two second spring rods 11 are provided.

[0036] The inner cavity of the box body 1 is slidably connected with a reset rod 13, the surface of the reset rod 13 is sleeved with a reset spring 14, and one end of the reset rod 13 is fixedly connected with a bevel block 15; one end of the reset rod 13 is fixedly connected with a push wheel 20, and the side of the push wheel 20 near the inner cavity is connected to a limiting pin through a thread, and the inner cavity of the bevel block 15 is provided with a semicircular hole, and the inner cavity of the semicircular hole is slidably connected to the surface of the limiting ball 10.

[0037] A fixed ring 16 is fixedly connected to the top of the box body 1, and a movable ring 17 is fixedly connected to one side of the box door 2. The inner cavity of the fixed ring 16 is movably connected to a rotating rod 18, and the surface of the rotating rod 18 is movably connected to the inner cavity of the movable ring 17.

[0038] One side of the tooth plate 12 is fixedly connected to a limiting block 19 , and the inner cavity of the box body 1 is provided with a limiting groove, and one side of the limiting block 19 is slidably connected to the inner cavity of the limiting groove.

[0039] The inner cavity of the box body 1 is provided with a square groove, and both ends of the lead screw 4 are rotatably connected to the square groove through bearings.

[0040] The inner cavity of the lower pressing block 7 is provided with a locking groove, and one end of the first spring rod 8 is fixedly connected to the inner cavity of the locking groove.

[0041] The teeth of the toothed plate 12 do not contact the front end or rear end of the inner wall of the box body 1, and only mesh with the teeth extending from the gear 5. The surface of the reset rod 13 is slidably connected to the front end and rear end of the top right side of the inner cavity of the box body 1, and one end extends to the outside of the box body 1, and the other end extends to the inside of the box body 1. One end of the reset spring 14 is fixed to the inner wall of the box body 1, and the other end is fixed to one side of the inclined block 15. One side of the inclined block 15 is fixed to the end of the reset rod 13 extending to the inner cavity of the box body 1. Three fixed rings 16 are fixedly connected to the left side of the top of the box body 1. Two movable rings 17 are fixedly connected to the left side of the box door 2 through a connecting block. The two movable rings 17 are located between the three fixed rings 16. The movable rings 17 and the fixed rings 16 are connected together by the connection of the rotating rod 18, so that the box door 2 can rotate;

[0042] One side of the limit block 19 is fixed to one side of the tooth plate 12, and the other side extends to the inner cavity of the limit groove and is slidably connected to the inner cavity of the limit groove, thereby limiting the movement of the tooth plate 12. The second spring rod 11 supports the tooth plate 12 and can drive the tooth plate 12 to reset. The two ends of the screw 4 are respectively rotatably connected to the two sides of the square groove inner cavity through bearings. The back of the sliding sleeve 6 fits with the rear end of the square groove inner cavity, thereby limiting the movement of the sliding sleeve 6. The teeth of the gear 5 do not contact the rear end of the square groove inner cavity. By removing the limit pin and pulling the push wheel 20, the box door 2 can be contact-limited. The positioning groove allows the first spring rod 8, the fixed block 9 and the limit ball 10 to be arranged on one side of the inner cavity of the lower pressure block 7.

[0043] The working process is as follows: when it is necessary to lock the loaded cigarettes inside the cigarette transport box, first, through the cooperation of the movable ring 17, the fixed ring 16 and the rotating rod 18, the box door 2 is rotated to close the box door 2. When the box door 2 is rotated to a certain extent, the bottom of the lower pressing block 7 presses the tooth plate 12, and the bottom of the lower pressing block 7 presses the inclined block 15, the tooth plate 12 moves downward, the tooth plate 12 drives the gear 5 to rotate, the gear 5 drives the lead screw 4 to rotate, the lead screw 4 drives the sliding sleeve 6 to move, and the sliding sleeve 6 drives the fastening plate 3 to move toward the inner cavity of the box body 1, thereby locking and limiting the cigarettes inside the box body 1 to prevent shaking during transportation, Causing damage to the cigarette box; the lower pressing block 7 squeezes the oblique block 15, causing the oblique block 15 to squeeze the reset rod 13, causing the reset rod 13 to move toward the outside of the box body 1. When one side of the oblique block 15 contacts the positioning groove on one side of the inner cavity of the lower pressing block 7, the reset spring 14 drives the reset rod 13 to rebound, causing the oblique block 15 to move toward the inner cavity of the positioning groove. The oblique block 15 squeezes the limiting ball 10, causing the limiting ball 10 to drive the first spring rod 8 to move upward. When the surface of the limiting ball 10 contacts the semicircular hole in the inner cavity of the oblique block 15, the first spring rod 8 drives the limiting ball 10 to contact the semicircular hole, jamming the oblique block 15. Finally, screwing in the limiting pin can lock the box door 2.

For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; and internal communication between two components. Those skilled in the art will understand the specific meanings of these terms in this disclosure / application based on specific circumstances.

[0045] The above is only a preferred embodiment of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present disclosure / application. These improvements and modifications should also be regarded as the scope of protection of the present disclosure / application.
