[0026] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figure 1-4The utility model provides a technical solution: a flywheel device of a rolling door with a locking mechanism, comprising a rolling door body 1, a second disc 4 is fixedly mounted on the top of the rolling door body 1, a connecting plate 3 is fixedly mounted on one side of the second disc 4, a first disc 2 is fixedly mounted on the other end of the connecting plate 3, a locking assembly 5 is fixedly mounted on the outer walls of the first disc 2 and the second disc 4, and an unlocking assembly 6 is provided on the locking assembly 5;

[0028] The locking assembly 5 includes a housing 51 and a telescopic rod 55. The housing 51 is fixedly mounted on the outer walls of the first disc 2 and the second disc 4. Integrated plates 53 are fixedly mounted on both ends of the telescopic rod 55. A latch 54 is fixedly mounted on the outer wall of the integrated plate 53.

[0029] A through hole is provided on the outer wall of the housing 51, and the latch 54 is slidably connected to the inner wall of the through hole. A spring 56 is sleeved on the outer wall of the telescopic rod 55, and both ends of the spring 56 are fixedly mounted on the outer wall of the integrated board 53. The inner wall of the housing 51 is fixedly connected to the side wall of the integrated board 53. An insert block 52 is fixedly mounted on the top of the rolling door body 1, and a slot is provided on the outer wall of the insert block 52.

[0030] The specific implementation method is as follows: when assembling the rolling door, align the plug block 52 set on the top of the rolling door body 1 with the shell 51, and push the plug block 52 to the outer wall of the shell 51. Initially, the plug block 52 will squeeze the pin 54, causing the pin 54 to move and retract into the interior of the shell 51. While the pin 54 moves, it drives the integrated board 53 to move, and the integrated board 53 squeezes the two ends of the spring 56 to form a compressed state. The telescopic rod 55 is in a retracted state at the same time. When the slot on the inner wall of the plug block 52 coincides with the pin 54, the elastic force of the spring 56 drives the integrated board 53 to insert the pin 54 into the slot on the inner wall of the plug block 52, locking it, and then welding the side wall of the second disc 4 to the top of the rolling door body 1 through welding equipment to complete the installation of the flywheel and the rolling door body 1.

[0031] The unlocking assembly 6 includes a drive column 61, which is rotatably mounted on the side wall of the housing 51. A transmission rod 62 is fixedly mounted on one end of the drive column 61. The transmission rod 62 passes through a through-hole provided on the side wall of the housing 51. A gear 63 is fixedly mounted on the other end of the transmission rod 62. A toothed bar 64 is slidably mounted on the inner wall of the housing 51. The gear 63 and the toothed bar 64 are meshedly connected. A connecting plate 65 is fixedly mounted on one end of the toothed bar 64. The other end of the connecting plate 65 is fixedly mounted on the outer wall of the integrated board 53.

[0032] The specific implementation method is as follows: when the rolling door body 1 or the flywheel needs to be replaced, it is only necessary to rotate the driving column 61. When the driving column 61 rotates, it drives the transmission rod 62 to rotate synchronously. The transmission rod 62 drives the gear 63. The gear 63 is meshed with the rack bar 64. When the gear 63 rotates, it drives the rack bar 64 to move. When the rack bar 64 moves, it drives the connecting plate 65 to move. The connecting plate 65 drives the integrated board 53 to move, so that it re-squeezes the two ends of the spring 56, removes the pin 54 from the slot on the inner wall of the plug block 52, and releases the locked state.

[0033] Working principle: When assembling the rolling door, align the plug 52 set on the top of the rolling door body 1 with the shell 51, and push the plug 52 to the outer wall of the shell 51. Initially, the plug 52 will squeeze the latch 54, causing the latch 54 to move and retract into the interior of the shell 51. When the latch 54 moves, it drives the integrated board 53 to move. The integrated board 53 squeezes the two ends of the spring 56 to form a compressed state. The telescopic rod 55 is in a retracted state at the same time. When the slot on the inner wall of the plug 52 coincides with the latch 54, the elastic force of the spring 56 drives the integrated board 53 to insert the latch 54 into the slot on the inner wall of the plug 52, locking it, and then welding it. The side wall of the second disc 4 is welded to the top of the rolling door body 1 to complete the installation of the flywheel and the rolling door body 1. When the rolling door body 1 or the flywheel needs to be replaced, it is only necessary to rotate the drive column 61. When the drive column 61 rotates, the transmission rod 62 is driven to rotate synchronously, and the transmission rod 62 drives the gear 63. The gear 63 is meshed with the rack bar 64. When the gear 63 rotates, the rack bar 64 is displaced. When the rack bar 64 is displaced, the connecting plate 65 is displaced. The connecting plate 65 drives the integrated plate 53 to displace, so that it re-squeezes the two ends of the spring 56, and the pin 54 is removed from the slot on the inner wall of the insert block 52 to release the locked state.

[0034] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
