Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figure 1-4 The utility model provides a technical solution: a linkage brake structure of a roller table, including a roller table body 1, a roller 2 is installed on the roller table body 1, and a "J"-shaped fixing plate 10 is arranged in the roller table body 1, a limit seat 9 with a through hole is fixed to the bottom of the fixing plate 10 by screw connection, and a limit rod 15 is movably penetrated in the through hole of the limit seat 9, this structure can make the limit rod 15 move under the limit of the limit seat 9, the fixing plate 10 makes the limit seat 9 firmly installed relative to the roller table body 1, the limit rod 15 is arranged horizontally, and the limit rod 15 is respectively sleeved with a damping spring 8 and a return spring 11 on both sides of the limit seat 9. This structure allows the limit rod 15 to be reset after the reset spring 11 is compressed when the limit rod 15 moves. When the limit rod 15 is reset, the damping spring 8 is used for damping. The upper end of the fixed plate 10 is symmetrically fixed with a rack 12, and the upper end of the rack 12 is meshed and connected with a brake gear 6. The sides of the brake gear 6 are respectively provided with a second connecting member 7, and the lower end of the second connecting member 7 is connected to a push plate 13. The side of the push plate 13 is provided with an inclined folding plate structure by bending, and a reinforcing connecting member 14 for stabilizing the position of the folding plate structure is welded on the push plate 13. This structure pushes the push plate 13 through the inclined folding plate position on the side of the push plate 13. Processing, so that the push plate 13 can drive the brake gear 6 to move linearly through the second connecting piece 7, and the brake gear 6 also rotates through the meshing of the bottom rack 12, so that the brake gear 6 drives the baffle gear 3 to rotate during the rotation, so that the baffle 5 on the baffle gear 3 rotates from a vertical state to a horizontal state, thereby realizing the transportation of goods, the baffle gear 3 is meshed and connected to the top of the brake gear 6, and the side of the baffle gear 3 is rotatably connected to the roller table body 1 through a rotating rod, the two ends of the limit rod 15 are respectively fixed to the reinforcement connecting piece 14 and the second connecting piece 7 by screw connection, and the shock-absorbing spring 8 is between the limit seat 9 and the second connecting piece 7, and reset The spring 11 is between the limit seat 9 and the reinforcement connector 14. This structure allows the push plate 13 to be pushed and subsequently reset through the limit of the limit rod 15. The reinforcement connector 14 strengthens the structure of the push plate 13. The baffle gear 3 is clamped and fastened with a first connector 4, and a baffle 5 is connected between the first connectors 4. The movement of the push plate 13 allows the brake gear 6 to roll on the rack 12 to realize the rotation of the baffle gear 3. The baffle 5 is vertically arranged in the free state of the reset spring 11. This structure enables the baffle 5 to be horizontally arranged to block the goods on the roller 2 when the push plate 13 is not pushed, thereby preventing the goods from slipping.

[0019] Working principle: When the roller table linkage brake structure is used, the roller table body 1 first transports the goods through the roller 2. When the push plate 13 is not pushed, the baffle 5 is in a vertical state to prevent the goods on the roller 2 from sliding outward. When the push plate 13 is pushed by the lifting transfer vehicle (ETV), the push plate 13 moves the brake gear 6 through the second connecting member 7, so that the brake gear 6 rotates through the rack 12, and the brake gear 6 drives the baffle gear 3 to rotate in the opposite direction, so that the baffle 5 fixed on the baffle gear 3 by the first connecting member 4 rotates from the vertical state It becomes horizontal, so that the translation of the goods on the roller 2 is not hindered. During the movement of the push plate 13, the limit rod 15 and the limit seat 9 are used to limit the position. At the same time, the push plate 13 compresses the reset spring 11 through the reinforcement connector 14, and the fixed plate 10 makes the limit seat 9 and the rack 12 firmly installed relative to the roller table body 1. When the ETV thrust exerted on the push plate 13 is released, the push plate 13 resets the brake, changes the rotation direction of the brake gear 6, and rotates the baffle 5 to the vertical state again. The shock-absorbing spring 8 plays a shock-absorbing role in the reset of the push plate 13, thereby completing a series of tasks.
