The side bar portion 202 is substantially perpendicular to the plate portion 201. Hinge holes 205 are formed at both ends of the side bar part 201, and hinge

rods

1024 and 6024 shown in fig. 3 pass through the corresponding hinge holes 205. The side rod 201 is further provided with a rotary connection portion 206 at both ends thereof, and the rotary connection portion 206 is rotatably connected to the gas springs 40 and 50 shown in fig. 3. In one embodiment, the rotation connection portion 206 is protruded from the side rod portion 201, and the gas springs 40 and 50 may be assembled to the rotation connection portion 206 by screws. The rotation connecting portion 206 is away from the end of the first link 21 with respect to the hinge hole 205. In one embodiment, the plate portion 201 and the side bar portion 202 may be integrally formed.

With continued reference to fig. 1-3, the structure of the second link 22 is similar to the structure of the first link 21 and will not be described again. The gas springs 40, 50 are hinged between the first link 21 and the second link 22. The gas springs 40, 50 and the linkage 20 cooperate to change the relative positions of the first 10 and second 60 links. An operator applies an acting force to the control panel 3000 to extend or contract the gas springs 40 and 50 in a free state, and the link mechanism 20 is rotated by the acting force and the supporting force of the gas springs 40 and 50, thereby lifting or lowering the control panel 3000. The lifting device 1000 has the advantages of simple structure, high reliability and low cost.

In one embodiment, the gas springs 40, 50 include a first gas spring 40 and a second gas spring 50 hingedly connected to opposite sides of the linkage 20, the first and second gas springs 40, 50 having the same force value. The trimming effect and the lifting force are provided by the two

gas springs

40 and 50. The same force value is used for the two

gas springs

40 and 50, so that the stability of the lifting process can be ensured. The first and second gas springs 40 and 50 are hinged to one end of the first link 21 and to the opposite end of the second link 22. One end of the first air spring 40 is hinged to one end of the first link 21 close to the first connector 10, and the other end is hinged to one end of the second link 22 close to the second connector 60. The second gas spring 50 is opposite to the first gas spring 40, and one end of the second gas spring 50 is hinged to one end of the first connecting rod 21 close to the first connecting member 10, and the other end is hinged to one end of the second connecting rod 22 close to the second connecting member 60. The first and second gas springs 40 and 50 are arranged in parallel.

In one embodiment, the first gas spring 40 comprises a free-form gas spring. The first air spring 40 includes a piston rod 401 and a cylinder 402, and the piston rod 401 is telescopically movable in the cylinder 402, thus adjusting the length of the first air spring 40. The first air spring 40 has first hinge holes 403 formed at both ends thereof, respectively at an end of the cylinder 402 away from the piston rod 401 and an end of the piston rod 401 extending out of the cylinder 402. The first hinge hole 403 and the rotation connecting portion 206 may be hinged by a screw.

The second gas spring 50 comprises a lockable gas spring that includes a release/lock mechanism 504. The second gas spring 50 is stopped at a position while the first gas spring 40 is stopped by locking the second gas spring 50 by the release/lock mechanism 504, or the second gas spring 50 and the first gas spring 40 are freely movable by releasing the second gas spring 50. The second gas spring 50 comprises a piston rod 501 and a cylinder 502, the piston rod 501 being telescopically movable within the cylinder 502, thus adjusting the length of the second gas spring 50. A release/lock mechanism 504 is fixed to the end of the piston rod 501 that extends out of the cylinder 502. Both ends of the second gas spring 50 are formed with second hinge holes 503, and the second hinge holes 503 are formed at the end of the cylinder 402 remote from the piston rod 401 and the end of the release/lock mechanism 504.

Referring to fig. 2 and 3, the lifting device 1000 includes a take-up wire 30 having one end connected to the release/lock mechanism 504 and a control mechanism (not shown) connected to the other end of the take-up wire 30, the control mechanism controlling the release/lock mechanism 504 by tightening or loosening the take-up wire 30. An operator can operate the control mechanism to tension the take-up and pay-off wire 30, and the release/lock mechanism 504 of the lockable gas spring 50 is pulled after the take-up and pay-off wire 30 is tensioned, so that the release/lock mechanism 504 is in a release state, and the lockable gas spring 50 is in a free state. When the control mechanism is deactivated to release the line 30, the line 30 no longer exerts a force on the release/lock mechanism 504, and the lockable gas spring 50 returns to a locked state, which is unchangeable in length. In one embodiment, the take-up and pay-off line 30 may be a Bowden line, but the present disclosure is not limited thereto.

When the control mechanism is operated to keep the lockable gas spring 50 in the free state, if an upward force is applied to the lifting device 1000, for example, an upward pulling force is applied thereto, the lockable gas spring 50 and the free gas spring 40 are extended, so that the parallelogram formed by the linkage mechanism 20, the hinge rod 1024 and the hinge rod 6024 is deformed. Specifically, the link mechanism 20 gradually tends to be vertical, and the articulated

levers

1024 and 6024 gradually tends to be horizontal, so that the relative heights of the first connector 10 and the second connector 60 in the vertical direction become large, thereby raising the control panel 3000 with respect to the machine table 2000, as shown in fig. 1. When the link mechanism 20 is in the vertical state, the height of the lifting device 1000 reaches the maximum, and the control panel 3000 is adjusted to the maximum height.

With continued reference to fig. 1-3, when a downward force, such as a downward pushing force, is applied to the lift 1000 while the lockable gas spring 50 is in the free state, the lockable gas spring 50 and the free gas spring 40 shorten, thereby deforming the parallelogram formed by the linkage mechanism 20, the hinge rod 1024, and the hinge rod 6024. Specifically, the link mechanism 20 gradually tends to be horizontal, and the hinge levers 1024 and 6024 gradually tends to be vertical, so that the relative heights of the first connector 10 and the second connector 60 in the vertical direction become smaller, thereby lowering the control panel 3000 relative to the machine table 2000.

When the lift 1000 reaches a desired height, the control mechanism can be released to release the take-up and pay-off wire 30, the take-up and pay-off wire 30 no longer exerts a pulling force on the release/lock mechanism 504, the release/lock mechanism 504 is reset to lock the lockable gas spring 50, the locking of the lockable gas spring 50 locks the linkage mechanism 20 and the free gas spring 40, limits the extension of the free gas spring 40, and the rotation of the linkage mechanism 20, so that the lift 1000 stays at that height. When the height of the lifting device 1000 needs to be adjusted again, the control mechanism can be operated to repeat the above operations.

In one embodiment, the control panel 3000 is provided with an operating knob 3010, and the control mechanism may be provided to the operating knob 3010. For example, a control mechanism in the form of a key is provided inside the middle of the operating knob 3010. An operator can hold the middle portion of the operating handle 3010 and hold the operating handle 3010 to depress the control mechanism, causing the take-up wire 30 to be pulled, thereby pulling the release/locking mechanism 504 of the lockable gas spring 50, causing the lockable gas spring 50 to be in a free state. At this time, the operator can press or lift the control panel 3000 down by operating the knob 3010 to adjust the height of the control panel 3000. Thereafter, the operator can release the operating knob 3010, no longer apply a force to the control mechanism on the operating knob 3010, and the take-up and pay-off wires 30 are loosened, thereby resetting the release/locking mechanism 504 of the lockable gas spring 50, and the lockable gas spring 50 is locked, thereby maintaining the control panel 3000 at a fixed height. The operation knob 3010 is provided to facilitate and facilitate the operation of the lifting device 1000. Further, the position of the medical apparatus 100 may also be moved by pushing or pulling the operation knob 3010. It should be noted that the control mechanism may be disposed in other forms or at other positions of the medical apparatus 100, and the present invention is not limited thereto.

In another embodiment, the gas springs 40 and 50 are both lockable gas springs. In yet another embodiment, the gas springs 40 and 50 are free-form gas springs, and the lift 1000 is released or locked by other release/locking mechanisms. In other embodiments, the lift 1000 may include more than three gas springs. In one embodiment, at least one of the three or more gas springs is a lockable gas spring. In another embodiment, more than three gas springs are free gas springs.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the scope of protection of the present application.
