[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-9 This utility model discloses an interlocking anti-tilting structure and an interlocking anti-tilting cabinet, including a plurality of single locks 1, which are interlocked by a linkage rod 2.
[0030] The single lock 1 includes an interlocking base 11, and the interlocking base 11 is internally provided with a sliding member 12 and two interlocking handles 13 for driving the sliding member 12. When one of the interlocking handles 13 drives the sliding member 12, it simultaneously locks the other interlocking handle 13.
[0031] Specifically, the sliding member 12 is provided with a return spring 14 inside, and the interlocking base 11 is provided with a positioning post 15 that abuts against one end of the return spring 14 inside.
[0032] In this embodiment, when the interlock handle 13 rotates, it drives the cam 131 to abut against the sliding member 12. The sliding member 12 moves to abut against the driving link 16. At the same time, the sliding member 12 compresses the return spring 14. The return spring 14 is designed so that when the sliding member 12 loses the abutment force of the interlock handle 13, it can quickly reset.
[0033] Specifically, one end of the sliding member 12 is provided with an arc-shaped notch 121 and both ends of the arc-shaped notch 121 are provided with positioning platforms 122, and one end of the interlock handle 13 is provided with a cam 131 that matches the arc-shaped notch 121 and the positioning platform 122.
[0034] In this embodiment, the arc-shaped notch 121 cooperates with the cam 131. When the interlock handle 13 rotates, the cam 131 can smoothly drive the slider 12, minimizing the noise from the interlocking parts. The positioning platform 122 is designed to hold the interlock handle 13 in place. When the user pulls open the drawer 41 and the moving part 3 drives the interlock handle 13 to rotate into place, the cam 131 will abut against the positioning platform 122 along the arc-shaped notch 121. Since the positioning platform 122 and the center of rotation of the interlock handle 13 are opposite, the interlock handle 13 and the slider 12 are locked together and cannot be reset. When the drawer 41 is closed, the moving part 3 resets and pushes the interlock handle 13 to disengage from the slider 12. The sliding key is reset by the return spring 14.
[0035] Specifically, the cam 131 is provided with an interlocking groove 132, and the two interlocking handles 13 are interlocked through the interlocking groove 132.
[0036] In this embodiment, in the single lock 1, when one of the two interlocking handles 13 rotates, its cam 131 will lock into the interlocking groove 132 of the other interlocking handle 13 after it has rotated to its position, preventing the other interlocking handle 13 from rotating and thus enabling the function of opening only one drawer 41 at a time.
[0037] Specifically, a drive link 16 is rotatably provided at one end of the interlock base 11. A positioning notch 17 and a positioning plate 18 are respectively provided on both sides of one end of the drive link 16, and an oblong hole 19 is provided inside the other end.
[0038] In this embodiment, when the sliding member 12 is driven by the interlock handle 13, the sliding member 12 abuts against the positioning notch 17, causing the driving linkage 16 to flip outward. Simultaneously, the driving linkage 16 moves the connecting rod 2 upward or downward through the oblong hole 19. Each connecting rod 2 corresponds to two single locks 1. The upper single lock 1 drives the connecting rod 2 upward, and the lower single lock 1 drives the connecting rod 2 downward. With this design, when the upper single lock 1 is pulled by the drawer 41 and drives the connecting rod 2 upward, the connecting rod 2 cannot move downward, thus locking the lower single lock 1 and preventing it from being used. Similarly, when the lower single lock 1 is pulled down by the drawer 41 to drive the linkage 2 downward, the linkage 2 cannot move upward, thus locking the upper single lock 1 and rendering it unusable. When the drive linkage 16 in the single lock 1 is locked, the positioning notch 17 will block the sliding member 12 from moving. The positioning plate 18 is set so that when the drive linkage 16 is not locked, the sliding member 12 can abut against the positioning notch 17 to drive the drive linkage 16 to flip. When the drive linkage 16 flips, it drives the positioning plate 18 to flip. After the positioning plate 18 abuts against the interlock base 11, the drive linkage 16 stops flipping.
[0039] Specifically, the linkage 2 is provided with a number of fixing members 21, and one side of the fixing member 21 is provided with a drive pin 22 that extends into one of the waist-shaped holes 19.
[0040] In this embodiment, the drive linkage 16 moves by engaging the drive pin 22 through the oblong hole 19.
[0041] Specifically, it also includes a movable component 3, the number of which is the same as the number of interlock handles 13, and the movable component 3 is sleeved with the end of the interlock handle 13 away from the cam 131.
[0042] In this embodiment, the movable part 3 is fixed on both sides of the drawer 41. When the drawer 41 is pulled open, the movable part 3 moves the interlock handle 13. When the drawer 41 is closed, the movable part 3 moves the interlock handle 13 to reset.
[0043] Specifically, at least one sound-absorbing component 31 is provided on one side of the inner wall of the movable component 3.
[0044] In this embodiment, the silencing component 31 is made of soft rubber, plush, elastic steel wire, etc. When the interlock handle 13 is reset, it collides with the silencing component 31. The silencing component 31 can reduce the sound generated by the collision and minimize the noise.
[0045] An interlocking anti-tilt cabinet includes a cabinet body 4 and an interlocking anti-tilt structure. The cabinet body 4 has several drawers 41 inside. The movable part 3 is fixedly installed on both sides of the drawer 41. The single lock 1 and the linkage rod 2 are both installed on both sides of the inner wall of the cabinet body 4. The single lock 1 can control the upper and lower drawers 41.
[0046] In use, each linkage 2 corresponds to two individual locks 1. The upper individual lock 1 drives the linkage 2 upward, and the lower individual lock 1 drives the linkage 2 downward. With this design, when the upper individual lock 1 is pulled by the drawer 41, causing the linkage 2 to move upward, the linkage 2 cannot move downward, thus locking the lower individual lock 1 and rendering it unusable. Similarly, when the lower individual lock 1 is pulled by the drawer 41, causing the linkage 2 to move downward, the linkage 2 cannot move upward. The movement causes the upper single lock 1 to be locked and unusable. A single single lock 1 can control two drawers 41, one of which is pulled out. The drawer 41 moves the interlock handle 13 of the single lock 1 via the moving part 3. The rotation of the interlock handle 13 moves the sliding part 12 via the cam 131, realizing the interlock between the interlock handle 13 and the sliding part 12. One end of the sliding part 12 abuts against the driving link 16. The driving link 16 drives the connecting rod 2 to move, realizing the interlock between the upper and lower single locks 1.
[0047] In summary, this interlocking anti-tipping structure and cabinet allows for the control of two drawers 41 by a single lock 1. Pulling out one drawer 41 locks out the other, preventing it from being pulled out. Multiple drawers 41 can be interlocked via the drive linkage 16 and the linkage 2. Pulling out one drawer 41 locks out the remaining drawers, achieving the purpose of combined interlocking. This effectively prevents the danger of the cabinet 4 tipping over due to the simultaneous opening of multiple drawers 41, making it safer to use. It not only protects personnel safety but also property safety, avoiding economic losses. It is widely used in steel cabinets, wooden cabinets, and filing cabinets, and has broad application prospects.
