[0028] Through the connection of auxiliary assembly 5, the active cover plate 2 drives the passive cover plate 3 to rotate together in the process of rotating, and the two cooperate with each other, thereby reducing the friction between the pulley 31 of the passive cover plate 3 and the box body 1, avoiding the phenomenon that the passive cover plate 3 is jammed, and greatly improving the service life.

[0029] The auxiliary component 5 includes: a housing 51, a support block 52, a connecting rod 53, a roller 55, a rack 54, a gear 56, a connecting seat 57, and a slide groove 58; one end of the housing 51 is provided with a circular hole 511, a plurality of the support blocks 52 are disposed in the inner cavity of the housing 51, and the connecting rod 53 is movably disposed in the inner cavity of the housing 51;

[0030] The connecting rod 53 moves through the middle of the multiple support blocks 52, and one end of the connecting rod 53 passes through the circular hole 511. One end of the connecting rod 53 is provided with a roller 55, and the other end is provided with a rack 54. The roller 55 is located on the outside of one end of the outer shell 51.

[0031] A gear 56 is provided on the inner wall of the other end of the inner cavity of the outer shell 51, and the gear 56 meshes with the rack 54. The gear 56 is located below the rack 54, and the axis of the gear 56 is perpendicular to the outer shell 51.

[0032] The connecting seat 57 is disposed on the inner wall of the top of the housing 1. The connecting seat 57 is rotatably connected to the active cover plate 2. The connecting seat 57 is provided with a sliding groove 58, and the roller 55 is movably located inside the sliding groove 58.

[0033] The connecting seat 57 is used to support and connect the entire active cover plate 2. The slide groove 58 provided on it will slide in cooperation with the roller 55, and transmit power to the gear 56 through the connecting rod 53, thereby driving the passive cover plate 3 to rotate.

[0034] The chute 58 has an arc-shaped structure, and the distance between the opening of the chute 58 and the active cover plate 2 is greater than the distance between the bottom of the chute 58 and the active cover plate 2.

[0035] It should be noted that the rectangular distance between the groove opening and the bottom of the groove 58 and the active cover plate 2 is reduced. This is so that when the active cover plate 2 rotates, the roller 55 on the connecting rod 53 will rotate in the groove 58 and push the connecting rod 53 into the housing 51, so that the rack 54 on the connecting rod 53 drives the gear 56 to rotate, thereby transmitting power to the connecting shaft 32 and causing the passive cover plate 3 to rotate together with the active cover plate 2.

[0036] It should be noted that the distance between the groove opening and the bottom of the groove of the slide 58 and the active cover plate 2, the distance the rack 54 on the connecting rod moves, and the angle of rotation of the rack 54 driving the gear 56 are all precisely calculated and designed to ensure that when the active cover plate 2 rotates at a certain angle, the passive cover plate 3 also rotates at a certain angle, and the pulley 31 on the passive cover plate 3 will roll stably in the rectangular groove 11, reducing the friction between the pulley 31 and the housing 1 and greatly improving the service life.

[0037] The active cover plate 2 is provided with a first support seat 21 at the bottom, and the first support seat 21 is connected with the other end of the hydraulic drive rod 4. The active cover plate 2 is provided with a connecting ring 22 on one side. The first support seat 21 is used to connect with the hydraulic drive rod 4, and the active cover plate 2 is driven to rotate by the hydraulic drive rod 4. The connecting ring 22 on the active cover plate 2 is rotatably connected with the connecting shaft 32 on the passive cover plate 3, so as to realize the hinging between the active cover plate 2 and the passive cover plate 3.

[0038] The passive cover plate 3 is provided with a connecting shaft 32 on one side, the connecting shaft 32 is rotatably located in the connecting ring 22, one end of the connecting shaft 32 penetrates through the shell 51 and is connected with the gear 56, and the connecting shaft 32 is perpendicular to the shell 51. The other side of the passive cover plate 3 is provided with a plurality of pulleys 31 at the bottom, and the plurality of pulleys 31 are located in the rectangular groove 11 respectively.

[0039] It should be noted that the connecting shaft 32 on the passive cover plate 3 is fixed on one side of the passive cover plate 3. The connecting shaft 32 drives the passive cover plate 3 to rotate while rotating. In the process of rotating and moving, the pulley 31 rolls in the rectangular groove 11, so that the passive cover plate 3 is quickly opened and closed.

[0040] The second support seat 12 is arranged on the inner wall of the short side of the box body 1, and the second support seat 12 is connected with one end of the hydraulic drive rod 4. The second support seat 12 is used to support the hydraulic drive rod 4, so that the hydraulic drive rod 4 can rotate in the inner wall of the box body 1 while pushing the active cover plate 2 to move.

[0041] Working process: when the cover plate on the box body 1 needs to be opened, the hydraulic drive rod 4 is started by control, and extends upward to push the active cover plate 2 to rotate upward. In the process of rotating, the roller 55 on the auxiliary assembly 5 will slide downward in the sliding groove 58, and push the connecting rod 53 to move inward, so as to drive the rack 54 to move. Since the rack 54 and the gear 56 are engaged with each other, the gear 56 will be driven to rotate. The connecting shaft 32 will be driven to rotate by the gear 56, and the passive cover plate 3 will be driven to rotate by the connecting shaft 32. The pulley 31 on the passive cover plate 3 will slide in the rectangular groove 11 on the inner wall of the box body 1, so as to realize the opening of the cover plate on the top of the box body 1.

[0042] When the cover needs to be closed, the hydraulic drive rod 4 is controlled to retract, pulling the main cover 2 to rotate downward. In the process of rotating, the roller 55 on the auxiliary assembly 5 will slide upward in the sliding groove 58, pulling the connecting rod 53 to move outward, thereby driving the rack 54 to move. Since the rack 54 and the gear 56 are engaged with each other, the gear 56 will be pulled to rotate reversely. The connecting shaft 32 will be rotated by the gear 56, and the passive cover 3 will be rotated reversely by the connecting shaft 32. The pulley 31 on the passive cover 3 will slide in the rectangular groove 11 on the inner wall of the box 1, so that the included angle between the main cover 2 and the passive cover 3 is 180°, and the box 1 is covered.
