[0033] See Figure 1-Figure 4 The present invention provides a locking device for being set on a medical connection cart, the medical connection cart including a mounting frame 1, the locking device including a locking cam 2, a first cable 3, a second cable 4 and a locking member 5, the locking member 5 being used to be rotatably connected to the mounting frame 1, one end of the locking member 5 being connected to the locking cam 2, and the two ends of the locking cam 2 being respectively provided with a first connecting end 21 and a second connecting end 22.

[0034] See Figure 2-Figure 3 The first cable 3 is arranged near the first connecting end 21, and the first cable 3 is fixedly connected to the second connecting end 22 for pulling the locking cam 2 to rotate toward the first direction 10, so as to control the locking member 5 to rotate relative to the mounting frame 1 to achieve unlocking; the second cable 4 is arranged near the second connecting end 22, and the second cable 4 is fixedly connected to the first connecting end 21 for pulling the locking cam 2 to rotate toward the second direction 100, so as to control the locking member 5 to rotate relative to the mounting frame 1 to achieve locking.

[0035] Specifically, the first direction 10 is a counterclockwise direction, and the second direction 100 is a clockwise direction.

[0036] In this embodiment, the locking device is used to be set on a medical connection cart, and the medical connection cart includes a mounting frame 1, and the mounting frame 1 is a mounting carrier. The locking member 5 is rotatably set on the mounting frame 1 and the locking cam 2 is connected to one end of the locking member 5. Since the first cable 3 is fixedly connected to the second connecting end 22, when the first cable 3 is pulled, the first cable 3 pulls the locking cam 2 to rotate toward the first direction 10, thereby putting the locking member 5 in an unlocked state. At this time, the infant incubator or warming table can be pushed close to the locking member 5 of the medical connection cart; thereafter, the second cable 4 is pulled. Since the second cable 4 is fixed to the first connecting end 22, the locking cam 2 is fixedly connected to the first connecting end 22, when the first cable 3 is pulled, the first cable 3 pulls the locking cam 2 to rotate toward the first direction 10, thereby putting the locking member 5 in an unlocked state. The end 21 is fixedly connected, so that the second cable 4 pulls the locking cam 2 to rotate toward the second direction 100, so that the locking member 5 is in a locked state. At this time, the locking member 5 can engage and limit the infant incubator or warming table to connect the infant incubator or warming table with the medical connection cart; wherein, the first cable 3, the second cable 4 and the locking cam 2 are coordinated to lock or unlock the locking member 5, so that the medical connection cart and the infant incubator or warming table can be detachably connected, which is convenient for quickly connecting and disassembling the medical connection cart and the infant incubator or warming table. It has a simple structure and is easy to operate, which is conducive to improving work efficiency and facilitating the smooth progress of medical work.

[0037] See Figure 4 Preferably, the locking member 5 includes a rotating rod 51 and a lock buckle 52. The rotating rod 51 can be rotatably connected to the mounting frame 1 around its own axis. One end of the rotating rod 51 is connected to the locking cam 2, and the rotating rod 51 is used to rotate with the locking cam 2; the other end of the rotating rod 51 is connected to the lock buckle 52, and the lock buckle 52 protrudes from the side wall of the rotating rod 51.

[0038] Specifically, the rotating rod 51 is arranged horizontally and can rotate around its own axis. When the lock buckle 52 rotates to a horizontal state with the rotating rod 51, the locking member 5 is in an unlocked state; when the lock buckle 52 rotates to a vertical state with the rotating rod 51, the locking member 5 is in a locked state.

[0039] In this embodiment, when the first cable 3 is pulled, the first cable 3 pulls the locking cam 2 to rotate toward the first direction 10. At this time, the lock buckle 52 and the rotating rod 51 follow the locking cam 2 to rotate toward the first direction 10. When the lock buckle 52 can be rotated to a horizontal state, the locking member 5 is in an unlocked state, so as to push the infant incubator or warming table close to the locking member 5 of the medical connecting cart; when the second cable 4 is pulled, the second cable 4 pulls the locking cam 2 to rotate toward the second direction 100. At this time, the lock buckle 52 and the rotating rod 51 follow the locking cam 2 to rotate toward the second direction 100. When the lock buckle 52 rotates to a vertical state, the lock buckle 52 engages with the base on the infant incubator or warming table to achieve the connection between the two. At this time, the locking member 5 is in a locked state.

[0040] See Figure 4 Preferably, the locking device further includes a fixing seat 53, a first limiting portion 501 and a second limiting portion 502, the fixing seat 53 is fixed on the mounting frame 1, and the rotating rod 51 passes through the fixing seat 53 and is rotatably connected to the fixing seat 53;

[0041] The first limiting portion 501 is fixed to the fixing seat 53. A limiting groove 503 is provided on the side wall of the first limiting portion 501. A guiding slope 504 is provided in the limiting groove 503. The guiding slope 504 is inclined from the inside of the limiting groove 503 toward the end side wall of the first limiting portion 501. The second limiting portion 502 is fixed to the side of the locking cam 2 facing the fixing seat 53. A limiting protrusion 505 is provided on the side wall of the second limiting portion 502.

[0042] When the second limiting portion 502 rotates toward the first direction 10 along with the locking cam 2, the limiting protrusion 505 of the second limiting portion 502 moves along the guide slope 504 to the inside of the limiting groove 503, and the second limiting portion 502 moves relative to the first limiting portion 501 along the axial direction of the rotating rod 51 to approach the first limiting portion 501; when the second limiting portion 502 rotates toward the second direction 100 along with the locking cam 2, the limiting protrusion 505 of the second limiting portion 502 moves along the guide slope 504 to the outside of the limiting groove 503, and the second limiting portion 502 moves relative to the first limiting portion 501 along the axial direction of the rotating rod 51 to move away from the first limiting portion 501.

[0043] Specifically, the first limiting portion 501 is a cylindrical structure, and the side wall of the first limiting portion 501 is fixedly connected to the fixing seat 53 by bolts. The first limiting portion 501 is sleeved on the rotating rod 51, and the rotating rod 51 passes through the first limiting portion 501 and is rotatably connected to the first limiting portion 501; the second limiting portion 502 is a cylindrical structure, and the second limiting portion 502 is fixedly sleeved on the rotating rod 51, and one end face of the second limiting portion 502 is opposite to one end face of the first limiting portion 501, and the end face of the second limiting portion 502 opposite to the first limiting portion 501 is provided with a limiting protrusion 505, and the end face of the first limiting portion 501 opposite to the second limiting portion 502 is provided with a limiting groove 503; when the lock buckle 52 is in the unlocked state, the limiting protrusion 505 is located inside the limiting groove 503.

[0044] When the second limiting portion 502 rotates along the locking cam 2 toward the first direction 10, the limiting protrusion 505 of the second limiting portion 502 moves along the guide inclined surface 504 to the inside of the limiting groove 503, and the second limiting portion 502 moves along the axial direction of the rotating rod 51 relative to the first limiting portion 501 to approach the first limiting portion 501, causing the locking cam 2, the rotating rod 51 and the lock buckle 52 to move axially away from the medical connection cart. At this time, the distance between the lock buckle 52 and the fixed seat 53 is expanded, and the lock buckle 52 moves in the direction away from the medical connection cart. At the same time, the lock buckle 52 rotates to a horizontal state to achieve unlocking; when the second limiting portion 502 rotates along the locking cam 2 toward the second direction 100, the limiting protrusion 505 of the second limiting portion 502 moves along the The guide inclined surface 504 moves to the outside of the limiting groove 503, and the limiting protrusion 505 is gradually pushed by the guide inclined surface 504 to move in the direction away from the limiting groove 503, and the second limiting portion 502 moves axially along the rotating rod 51 relative to the first limiting portion 501 to move away from the first limiting portion 501, and the locking cam 2, the rotating rod 51 and the locking buckle 52 move axially to approach the medical connection cart. At this time, the distance between the locking buckle 52 and the fixing seat 53 is reduced, and at the same time, the locking buckle 52 is rotated to a vertical state to achieve locking; wherein, this structure makes the locking buckle 52 close to the fixing seat 53 when the locking buckle 52 is locked, so that the locking buckle 52 and the fixing seat 53 can be gradually clamped and engaged with the base on the infant incubator or warming table to achieve connection between the two, which is conducive to improving the locking connection effect.

[0045] See Figure 4Preferably, the locking member 5 further includes a reset spring 506 , which is sleeved on the outer wall of the rotating rod 51 , and the reset spring 506 is located between the lock buckle 52 and the fixing seat 53 .

[0046] When the second limiting portion 502 is pulled and the second limiting portion 503 is rotated toward the second direction 100 along the locking cam 2, the limiting protrusion 505 of the second limiting portion 502 gradually moves out of the limiting groove 503 of the first limiting portion 501 along the guiding inclined surface 504, and the second limiting protrusion 99 is gradually pushed by the guiding inclined surface 504 to move in the direction away from the limiting groove 503, and the second limiting portion 502, the locking cam 2, the rotating rod 51 and the locking buckle 52 are axially moved, and the locking buckle 52 moves toward the direction close to the fixing seat 53. Since the return spring 506 is sleeved on the outer wall of the rotating rod 51 and the return spring 506 is located between the locking buckle 52 and the fixing seat 53, the return spring 506 is squeezed and elastically deformed; when unlocking, the first limiting portion 502 is pulled and the second limiting portion 502 is gradually moved out of the limiting groove 503 of the first limiting portion 501 along the guiding inclined surface 504. When the locking cam 2 is unlocked, the locking cam 200 is in a state of rotation, and the locking cam 200 is in a state of rotation, so that the locking cam 200 moves in a direction away from the fixing seat 53, and the distance between the locking cam 200 and the fixing seat 53 increases. At the same time, the locking cam 200 is in a state of rotation, so that the locking cam 200 moves in a direction away from the fixing seat 53, and the distance between the locking cam 200 and the fixing seat 53 increases. At the same time, the locking cam 200 is in a state of rotation, so that the locking cam 200 moves in a direction away from the fixing seat 53, and the distance between the locking cam 200 and the fixing seat 53 increases. At the same time, the locking cam 200 is in a state of rotation, so that the locking cam 200 moves in a direction away from the fixing seat 53, and the distance between the locking cam 200 and the fixing seat 53 increases. At the same time, the locking cam 200 is in a state of rotation, so that the locking cam 200 moves in a direction away from the fixing seat 53, and the locking cam 200 moves in a direction away from the fixing seat 53.
