[0022] Please see Figure 1-5 This utility model provides a technical solution: an integrated medical trolley cabinet safety locking mechanism, including a trolley cabinet 6, a safety locking mechanism 2 at the bottom of the trolley cabinet 6, a movable frame 9, a fixing cylinder 5 fixed at each of the four ends of the movable frame 9, a rubber ring 4 fixed at the bottom of the fixing cylinder 5, an installation rod 14 slidably connected inside the fixing cylinder 5, the top of the installation rod 14 fixedly connected to the bottom of the trolley cabinet 6, a universal wheel 3 installed at the bottom of the installation rod 14, a fixing rod 12 slidably connected inside the movable frame 9, the top of the fixing rod 12 fixedly connected to the bottom of the trolley cabinet 6, two locking holes 19 on the outer side wall of the fixing rod 12, a fixing frame 13 fixed at the bottom of the fixing rod 12, and the top of the fixing frame 13 and the trolley cabinet 6 fixedly connected to the fixing rod 12. The bottom of the cabinet 6 is fixedly connected, and a support spring 10 is sleeved on the outside of the fixed rod 12 below the movable frame 9. The movable frame 9 has a storage hole 20 inside, and a push spring 21 is fixed inside the storage hole 20. A locking block 22 is fixed to the other end of the push spring 21. Two L-shaped plates 23 are fixed to the bottom of the movable frame 9, so that multiple casters 3 can be locked. The elastic force of the support spring 10 is greater than the sum of the weight of the movable frame 9, four fixed cylinders 5, four rubber rings 4 and two L-shaped plates 23, so that they can be pushed upward. Two reinforcing rods 8 are slidably connected inside the L-shaped plate 23. The top of the reinforcing rods 8 is fixedly connected to the bottom of the trolley cabinet 6, so that the L-shaped plate 23 can be limited, thus preventing the L-shaped plate 23 from bending downward.
[0023] The bottom of the L-shaped plate 23 is provided with a control mechanism 1, which includes a movable plate 11. A fixed frame 17 is fixed to the bottom of the L-shaped plate 23. The bottom of the fixed frame 17 is rotatably connected to the movable plate 11. A through hole 16 is provided at the top of the L-shaped plate 23. A pull rope 18 is provided inside the L-shaped plate 23. The end of the pull rope 18 away from the fixed rod 12 is fixedly connected to the inner wall of the through hole 16. The left end of the right pull rope 18 passes through the movable frame 9 and is fixedly connected to the locking block 22. The right end of the right pull rope 18 passes through the movable frame 9 and is fixedly connected to the outer wall of the right pull rope 18. The outer wall of the pull rope 18 is movably connected to the pressure rod 15. The bottom of the pressure rod 15 is fixedly connected to the top of the movable plate 11. This can control the movement of the locking block 22, thereby releasing the safety locking mechanism 2. A torsion spring 7 is provided inside the movable plate 11. The two ends of the torsion spring 7 are fixedly connected to the movable plate 11 and the fixed frame 17 respectively. This can provide support for the movable plate 11 and prevent the movable plate 11 from falling and pulling the pull rope 18.
[0024] When in operation, step down on the L-shaped plate 23. The L-shaped plate 23 moves the moving frame 9, the fixed cylinder 5, and the rubber ring 4 downwards. The rubber ring 4 presses against the rollers 3 of the universal wheels. When the moving frame 9 descends, it moves the locking block 22. The locking block 22 descends and locks into the lower locking hole 19. In this way, the four rubber rings 4 descend and simultaneously prevent the four universal wheels 3 from rotating, improving the stability of the lock and preventing the trolley cabinet 6 from moving and hitting others. When it is necessary to move, use your foot to push the movable plate 11 upwards. The movable plate 11 moves the pressure rod 15. The pressure rod 15 pulls the pull rope 18, and the pull rope 18 pulls the locking block 22. The locking block 22 moves out of the lower locking hole 19. In this way, the support spring 10 pushes the moving frame 9, the fixed cylinder 5, and the rubber ring 4 upwards. The rubber ring 4 separates from the universal wheels 3, releasing the lock. Now the device can be pushed to move.
