The adapter device 10 can lift the traction frame 20 relative to the guide mechanism 31, and this process can also be considered as lifting the traction frame 20 relative to the auxiliary mounting platform 30 by the adapter device 10. The traction frame 20 may also be lowered into the guide mechanism 31, which process may also be considered as the traction frame 20 being lowered into the auxiliary mounting platform 30.

The traction frame 20 is mounted on the switching device 10 in such a way that the hanging piece 212 is firstly hung on the hanging part 121, and then the bed body 101 is lifted up or the auxiliary mounting platform 30 is lowered down, so that the switching device 10 lifts the traction frame 20 relative to the guiding mechanism 31 or the auxiliary mounting platform 30. During the process of lifting the traction frame 20 by the switching device 10 to leave the guiding mechanism 31 or the auxiliary mounting platform 30, the limiting assembly 213 is automatically moved out of the limit of the guiding mechanism 31 to be locked with the limiting part 122.

The process of disassembling the traction frame 20 is as follows, firstly, the auxiliary installation platform 30 is moved to the operating table 100, then the bed body 101 is controlled to descend or the auxiliary installation platform 30 is controlled to ascend, the traction frame 20 falls to the guide mechanism 31 or the auxiliary installation platform 30, in the process that the traction frame 20 falls to the guide mechanism 31 or the auxiliary installation platform 30, the guide mechanism 31 automatically guides the limiting component 213 to unlock with the limiting part 122, and the hanging piece 212 is separated from the hanging part 121, namely, the disassembly of the traction frame 20 is completed.

It should be noted that, the traction frame system 200 may be provided without the auxiliary mounting platform 30, for example, in another embodiment, the traction frame system 200 further includes a frame (not shown) that is mounted on the bed 101 in a retractable manner along the length direction of the bed 101, the frame is mounted on the bed 101 in a liftable manner along the height direction of the bed 101, the guiding mechanism 31 is disposed on the frame, the traction frame 20 is mounted as follows, the frame is pulled out from the bed 101 first, then the adapter device 10 is mounted on the bed 101 of the operating bed 100, and naturally, the adapter device 10 is mounted on the bed 101 of the operating bed 100 first, and then the frame is pulled out from the bed 101. Then, the traction frame 20 is placed on the frame, the guide mechanism 31 limits the limit component 213 to be in an unlocking state, then the bed body 101 is controlled to descend or the frame is controlled to ascend, the hanging part 121 is moved to the lower side of the hanging part 212, then the frame is moved, the hanging part 212 is hung on the hanging part 121, finally the bed body 101 is controlled to ascend or the frame is controlled to descend, the transfer device 10 lifts the traction frame 20 relative to the frame, the traction frame 20 is separated from the frame, namely, the installation of the traction frame 20 is completed, after the installation of the traction frame 20 is completed, the frame can be pushed back to be in a storage state with the bed body 101, and in the process that the traction frame 20 is separated from the frame, the limit component 213 is automatically moved to be locked with the limit part 122, so as to limit the movement and/or overturning of the connection mechanism 21 relative to the transfer device 10.

When the user removes the traction frame 20, the frame can be pushed back to be in a storage state with the bed 101.

In the operating table system 1000 provided in this embodiment, by setting the guiding mechanism 31, in the process that the transferring device 10 lifts the traction frame 20 to leave the guiding mechanism 31, the limiting component 213 is automatically moved to be locked with the limiting portion 122 after being separated from the limitation of the guiding mechanism 31, and the locking of the limiting component 213 and the limiting portion 122 does not need manual operation, so that the installation of the traction frame 20 is simple and efficient. In some embodiments, during the process of detaching the traction frame 20 from the adapter device 10 and installing the traction frame 20 on the guiding mechanism 31 or the auxiliary installing platform 30, the guiding mechanism 31 automatically guides the limiting component 213 to be separated from the limiting part 12 for limiting, and manual operation is not needed, so that the detachment of the traction frame 20 is simple and efficient.

As shown in fig. 2, in some embodiments, the bed 101 includes a waist plate/back plate 1011 and a leg plate, the side portion of the waist plate/back plate 1011 is provided with a connection structure, the leg plate is detachably connected with the connection structure, and the adapter device 10 is detachably connected with the connection structure, that is, the adapter device 10 and the leg plate share one connection structure, in use, the leg plate is detached from the waist plate/back plate 1011 first, and then the adapter device 10 is mounted on the connection structure of the waist plate/back plate 1011. In this embodiment, the complexity of the device can be reduced by sharing the connection structure. Of course, the arrangement is not limited to the above, for example, in other embodiments, the two sides of the bed 101 are provided with side rails, and the adapter device 10 may be mounted on the side rails according to practical design requirements.

As shown in fig. 2, in some embodiments, the auxiliary mounting platform 30 further includes a movable cart 32, and the guide mechanism 31 is mounted to the movable cart 32. In this embodiment, by providing the auxiliary mounting platform 30 further including the movable trolley 32, the movement of the auxiliary mounting platform 30 is facilitated, which is advantageous in improving the mounting efficiency of the traction frame 20.

As shown in fig. 3-6, in some embodiments, the stop 122 includes a boss 1221, the boss 1221 including a first side 122a and a second side 122b opposite the first side 122a, the second side 122b of the boss 1221 facing the traction mechanism 22. The stop assembly 213 includes a catch 2131, the catch 2131 being rotatably coupled to the body 211, the catch 2131 limiting upward rotation of the traction frame 20 relative to the adapter 10 by hooking the first side 122a of the boss 1221. During the descent of the traction frame 20 to the auxiliary mounting platform 30, the guide mechanism 31 pushes the hooks 2131 to rotate to disengage from the protrusions 1221, and during the lifting of the traction frame 20 from the auxiliary mounting platform 30 by the adapter 10, the hooks 2131 disengage from the limitations of the guide mechanism 31 and automatically rotate to engage with the first sides 122a of the protrusions 1221.

As shown in fig. 7, in some embodiments, the hook 2131 is rotatably connected to the main body 211 about an axis M that extends in a width direction of the draft gear 20. The width direction of the traction frame 20 refers to a direction that coincides with the width direction of the bed 101 when the traction frame 20 is mounted on the bed 101, and this definition is used below. That is, the hook 2131 is rotatably connected with the main body 211 on a vertical plane, in this embodiment, during the process of lifting the traction frame 20 by the switching device 10 to leave the auxiliary mounting platform 30, the hook 2131 is separated from the limitation of the guiding mechanism 31, and can automatically rotate to be matched with the first side 122a of the boss 1221 under the action of gravity of the hook 2131, without the assistance of other driving components, and thus the effect of simplifying the mechanism can be achieved.

It should be noted that the vertical plane is the orientation of the operating table system 1000 in the normal use state, and the definition is as follows.

Of course, the hook 2131 may be rotatably connected to the main body 211 in a horizontal plane, so long as the hook 2131 can automatically rotate to be engaged with the first side 122a of the boss 1221 when it is released from the restriction of the guide mechanism 31. In this embodiment, an additional first drive assembly is required to drive the hook 2131 to rotate in a horizontal plane into engagement with the first side 122a of the boss 1221 when the hook 2131 is out of the limit of the guide mechanism 31. For example, in some embodiments, the first drive assembly includes a torsion spring that connects the hook 2131 and the body 211, the torsion spring providing torsion force to rotate the hook 2131 into engagement with the first side 122a of the boss 1221 when the hook 2131 is out of the limit of the guide mechanism 31.

It should be noted that the horizontal plane is for the orientation of the operating table system 1000 in the normal use state, and the definition will be used below.

As shown in fig. 5 and 6, in some embodiments, the spacing assembly 213 further includes a mating piece 2132, the mating piece 2132 extending from one side of the hook 2131. Wherein, during the descent of the traction frame 20 to the auxiliary mounting platform 30, the guide mechanism 31 cooperates with the cooperation piece 2132 to drive the hook 2131 to rotate out of engagement with the first side 122a of the boss 1221. Specifically, during the descent of the traction frame 20 to the auxiliary mounting platform 30, the guide mechanism 31 lifts the hook 2131 up to disengage from the first side 122a of the boss 1221 by pushing the fitting 2132 upward. Of course, the limiting assembly 213 may not be provided with the engaging piece 2132, and the guiding mechanism 31 may directly act on the hook 2131 to drive the hook 2131 to rotate to disengage from the first side 122a of the boss 1221 during the process of the traction frame 20 falling onto the auxiliary mounting platform 30, which may be determined according to practical design requirements.

It should be noted that the hook 2131 is not limited to a manner of rotationally connecting with the main body 211, for example, in other embodiments, as shown in fig. 3 to 6, the limiting portion 122 includes a protrusion 1221, the protrusion 1221 includes a first side 122a and a second side 122b opposite to the first side 122a, and the second side 122b of the protrusion 1221 faces the traction mechanism 22. The stop assembly 213 includes a catch 2131, the catch 2131 being slidably coupled to the body 211, the catch 2131 limiting upward rotation of the traction frame 20 relative to the adapter 10 by hooking the first side 122a of the boss 1221. Wherein, during the falling of the traction frame 20 to the auxiliary mounting platform 30, the guide mechanism 31 pushes the hook 2131 to move to be separated from the boss 1221, and during the lifting of the traction frame 20 by the switching device 10 to leave the auxiliary mounting platform 30, the hook 2131 is separated from the limitation of the guide mechanism 31 and automatically moves to be matched with the first side 122a of the boss 1221.

In this embodiment, the hook 2131 may be slidably connected with the main body 211 in the vertical direction, and the hook 2131 is separated from the limitation of the guiding mechanism 31, and may automatically slide to match with the first side 122a of the boss 1221 under the action of gravity, without the assistance of other driving components, so as to achieve the effect of simplifying the mechanism.

Of course, the hook 2131 may be slidably connected to the main body 211 in the horizontal direction, so long as the hook 2131 can automatically slide to engage with the first side 122a of the boss 1221 when it is out of the limit of the guide mechanism 31. In this embodiment, an additional second drive assembly is required to drive the hook 2131 to automatically slide in a horizontal direction into engagement with the first side 122a of the boss 1221 when the hook 2131 is out of the limit of the guide mechanism 31. For example, in some embodiments, the first drive assembly includes a spring that connects the hook 2131 and the body 211, the spring providing a spring force that causes the hook 2131 to slide into engagement with the first side 122a of the boss 1221 when the hook 2131 is out of the limit of the guide mechanism 31.

In some embodiments, the number of the adaptor devices 10 is two, the two adaptor devices 10 are arranged at intervals along the width direction of the traction frame 20, and the opposite sides of the two adaptor devices 10 are provided with protrusions 1221. When the traction frame 20 is mounted on the adapter device 10, the main body 211 is located between the two adapter devices 10, and hooks 2131 are arranged on both sides of the main body 211 along the width direction of the traction frame 20. With this embodiment, the effect of reinforcing the locking of the stopper assembly 213 and the stopper 122 can be achieved.

It should be noted that the limiting assembly 213 is not limited to the manner of using the hook 2131, for example, in other embodiments, as shown in fig. 8 and 9, the limiting portion 122 includes a through hole 1222. The limiting assembly 213 comprises a lock tongue 2133, a driving piece 2134 and an unlocking piece 2135, wherein the lock tongue 2133 is telescopically installed on the main body 211, the driving piece 2134 is connected with the lock tongue 2133 and the main body 211, the driving piece 2134 is used for driving the lock tongue 2133 to extend out of the main body 211 to be matched with the through hole 1222, and the unlocking piece 2135 is used for driving the lock tongue 2133 to retract into the main body 211. Wherein, during the process of the traction frame 20 falling to the auxiliary mounting platform 30, the guide mechanism 31 pushes the unlocking piece 2135 to drive the lock tongue 2133 to withdraw from the through hole 1222, during the process of the switching device 10 lifting the traction frame 20 away from the auxiliary mounting platform 30, the unlocking piece 2135 is separated from the guide mechanism 31, and the driving piece 2134 drives the lock tongue 2133 to extend into the through hole 1222.

In some embodiments, the driving member 2134 includes a resilient member that provides a spring force to drive the locking tongue 2133 out of the body 211. The resilient member may be, but is not limited to, a spring.

It should be noted that the driving element 2134 is not limited to an elastic element, for example, in other embodiments, the driving element 2134 includes a first magnet and a second magnet, the first magnet is mounted on the main body 211, the second magnet is mounted on the lock tongue 2133, and the first magnet and the second magnet drive the lock tongue 2133 to extend out of the main body 211 through magnetic force.

The unlocking piece 2135 is provided with a sliding groove 2136, the sliding groove 2136 extends obliquely downwards along the direction that the lock tongue 2133 is retracted into the main body 211, the lock tongue 2133 is provided with a sliding column 2137, and the sliding column 2137 is embedded in the sliding groove 2136. It should be noted that the positions of the sliding groove 2136 and the sliding post 2137 may be reversed, that is, the sliding groove 2136 is provided on the lock tongue 2133, and the sliding post 2137 is provided on the unlocking piece 2135.

In some embodiments, the first groove 2111 extends in the width direction of the traction frame 20, the second groove 2112 extends in the height direction of the traction frame 20, and the unlocking piece 2135 extends partially from the bottom of the main body 211.

Defining the end of the chute 2136 near the bottom surface of the main body 211 as the bottom end D, the end opposite to the bottom end D as the top end T, taking the driving element 2134 as a spring, the chute 2136 is provided with the unlocking element 2135, the strut 2137 is provided with the lock tongue 2133 as an example, the operation of the limiting component 213 is as follows, in the process of lifting the traction frame 20 away from the auxiliary mounting platform 30, the unlocking element 2135 is away from the guiding mechanism 31, under the action of spring force of the guiding mechanism 31, the lock tongue 2133 extends out of the main body 211 along the first groove 2111 and into the through hole 1222 so as to lock with the switching device 10, in the process of extending the lock tongue 2133 out of the main body 211 along the first groove 2111, the strut 2137 moves from the bottom end D of the chute 2136 to the top end T of the chute 2136, and the unlocking element 2135 moves down along the second groove 2112 and extends out of the bottom of the main body 211.
