Wherein, the first rotating shaft 41 can be rotationally connected with the upright post 20, and the carrying platform 10 is fixedly connected with the first rotating shaft 41; alternatively, the first shaft 41 may be fixedly provided on the upright 20, and the carrier 10 is rotatably connected to the first shaft 41. In both of the above modes, the movement of the stage 10 about the first rotation axis a can be realized.

In the embodiment shown in fig. 3, the first rotation axis a is arranged in a direction perpendicular to the paper surface. When the carrying platform 10 is folded, the locking switch 43 is in a released state, and the connecting seat 42 can rotate clockwise around the first rotation axis a, so that the carrying platform 10 is driven to gradually approach the upright post 20; after being folded in place, the lock switch 43 is brought into a locked state, thereby fixing the stage 10. When the carrier 10 is unfolded, the locking switch 43 is in a released state, and the connecting seat 42 can rotate anticlockwise around the first rotation axis a, so that the carrier 10 is driven to be gradually far away from the upright post 20; after being unfolded in place, the lock switch 43 is brought into a locked state, thereby fixing the stage 10.

Further, the first rotating connection assembly 40 further includes an extension block 44 disposed on the upright 20, and the first rotating shaft 41 connects the connection seat 42 and the extension block 44; the extension block 44 is provided with a first locking hole 44a and a second locking hole 44b; when the carrier 10 is in the use state, the locking switch 43 locks the first locking hole 44a; when the carrier 10 is in the folded state, the lock switch 43 locks the second lock hole 44b.

Referring to fig. 4 and 5, the extension block 44 extends toward the outside of the column 20, having a certain length; the two ends of the first rotating shaft 41 penetrate through the extension block 44 and are connected with the connecting seat 42. By providing the extension block 44, the folding of the carrier 10 is facilitated, interference of the outer surface of the upright post 20 when the carrier 10 approaches the upright post 20 is avoided, and a good folding state cannot be maintained. Further, by adjusting the position of the first rotation shaft 41 on the extension block 44, or by replacing the extension blocks 44 with different lengths, the distance of the outward extension of the carrier 10 can be adjusted, thereby improving the applicability of the cart.

Wherein the first locking hole 44a and the second locking hole 44b are disposed at intervals along the circumference of a circle having a center on the first rotation axis a. At this time, the locking switch 43 is disposed on the connecting base 42, and when the locking switch 43 is in a locked state, the locking switch 43 is opposite to the locking hole (the first locking hole 44a or the second locking hole 44 b) and is locked with the locking hole under the action of elastic force; when the lock switch 43 is in the released state, the lock switch 43 is pulled out of the lock hole to facilitate rotation of the stage 10.

The specific structure of the locking switch 43 is conventional, and will not be described in detail.

Further, the first rotating connection assembly 40 further includes a limiting block 45 fixedly disposed on the upright 20; when the carrier 10 rotates around the first rotating shaft 41 and away from the upright post 20, the connecting seat 42 can contact the limiting block 45, so that the carrier 10 is prevented from rotating continuously.

In an embodiment, referring to fig. 1 and 3, the limiting block 45 is disposed above the connecting seat 42. In this embodiment, when the connecting seat 42 rotates counterclockwise around the first rotation shaft 41 and the carrier 10 is far away from the upright 20, one end of the connecting seat 42 moves toward the limiting block 45; after the end abuts against the limiting block 45, the limiting block 45 can prevent the connecting seat 42 from continuing to rotate; at this time, the other end of the connection base 42 receives the gravity of the carrier 10, so that the carrier 10 is kept in the use state.

Alternatively, by changing the height of the stopper 45, the projecting distance of the stage 10 and the inclination of the mounting surface thereof can be adjusted so that the stage 10 can better set the host device 1.

In other embodiments, the carrier 10 may be connected to the upright 20 by a rotational connection structure such as a hinge or a cam, and the present application is not limited to a rotational connection between two members.

Optionally, the base 30 is provided with a mounting groove 33, and the upright 20 is disposed in the mounting groove 33. At this time, both ends of the second shaft 52 penetrate the column 20 and are connected to the mounting groove 33.

To facilitate the rotation of the upright 20 in the mounting groove 33, one end of the upright 20 in the mounting groove 33 is a cambered surface, and at least the bottom of the mounting groove 33 is a cambered surface.

Further, the mounting groove 33 has a certain groove depth, and when the upright 20 is in the folded state, the positioning pin 52 is opposite to the groove wall of the mounting groove 33, and the groove wall can protect the positioning pin 52, so that the positioning pin 52 is received in the mounting channel, and the positioning pin 52 is prevented from protruding outwards.

Optionally, the second rotary connection assembly 50 further includes a connecting rod 55 connecting the locating pin 52 and the locating handle 53.

The connecting rod 55 can lengthen the locating pin 52. When the mounting groove 33 is provided on the base 30, the positioning pin 52 is extended by the connecting rod 55, so that the positioning handle 53 can be far away from the base 30, so that the operator can contact the positioning handle 53.

When the second rotating shaft 51 penetrates through the upright post 20 and the positioning pin 52 is disposed in the mounting channel, the connecting rod 55 is provided with a waist-shaped hole 55a in order to avoid mutual interference between the second rotating shaft 51 and the positioning pin 52, and the second rotating shaft 51 penetrates through the waist-shaped hole 55a to be connected with the base 30.

Wherein the extension of the waist-shaped hole 55a is arranged parallel to the movement direction of the positioning pin 52. It can be seen that the second rotating shaft 51 is fixedly arranged relative to the upright post 20; therefore, when the positioning handle 53 is pulled to move the positioning pin 52, the second rotating shaft 51 moves relatively along the waist-shaped hole 55 a.

Referring specifically to fig. 3, 10 and 11, when the upright 20 is in use, the waist-shaped hole 55a extends in a vertical direction, and both ends of the second rotating shaft 51 penetrate through the waist-shaped hole 55a and the upright 20 and are connected to the base 30. When the upright post 20 is folded, the positioning handle 53 is pulled, and the connecting rod 55 moves vertically upwards under the restriction of the second rotating shaft 51, so that the positioning pin 52 can be separated from the positioning hole 32 efficiently.

Optionally, the second rotatable connection assembly 50 further includes a bumper 56 disposed on the post 20 and/or the mounting groove 33; the bumper pad 56 is sandwiched between the first pole section 21 and the mounting groove 33 when the pole 20 is in use.

The second rotating connection assembly 50 may include only one cushion pad 56, or may include a plurality of cushion pads 56. The cushion 56 may be disposed on the first column section 21, within the mounting groove 33, or both the first column section 21 and the mounting groove 33 may be provided with the cushion 56.

The cushion 56 eliminates play between the upright 20 and the base 30 to prevent the upright 20 from rocking when in use.

The cushion 56 may be made of a flexible material such as rubber. The cushion pad 56 has a certain elasticity, and when the upright 20 is in the use state, the cushion pad 56 is clamped between the first column section 21 and the mounting groove 33, the cushion pad 56 is deformed by compression and has a tendency to return to the original state, so that the cushion pad 56 can abut against the first column section 21 and the mounting groove 33.

Alternatively, the head of the positioning pin 52 is provided in a spherical shape, and the positioning hole 32 is a tapered hole.

The head of the positioning pin 52 is a portion of the positioning pin 52 for inserting into the positioning hole 32. From the opening end of the positioning hole 32 inwards, the aperture of the positioning hole 32 is continuously reduced, so that the hole wall surface of the positioning hole 32 is an inclined plane.

By providing the head of the locating pin 52 with a spherical shape, on the one hand, the potential safety hazard caused by the sharp angle can be eliminated, and on the other hand, the closer to the end, the smaller the size of the head is due to the spherical characteristic, so that the locating pin 52 can be accurately inserted into the locating hole 32. In addition, the spherical head portion cooperates with the tapered hole to eliminate the gap between the positioning pin 52 and the positioning hole 32, thereby preventing the upright 20 from being shaken when in use.

It can be seen that, when the upright 20 extends along the first direction and has a larger height, even if the upright 20 is tilted toward the base 30 and finally extends along the second direction, the upright 20 still has a larger length in the second direction, which is not beneficial for the cart to be stored.

To reduce the length of the post 20 in the second direction, the post 20 may be further folded.

In one embodiment, the post 20 includes: a first column section 21, one end of the first column section 21 being connected to the base 30; the second column section 22, the other end of the first column section 21 is connected with the second column section 22, and the first column section 21 is rotatably connected with the second column section 22; when the medical trolley is converted from the use state to the folding state, the first column section 21 rotates around the second rotation axis b, and the second column section 22 rotates around the third rotation axis c; when the medical trolley is in the folded state, the first column section 21 is arranged in an extending mode along the second direction, and the second column section 22 is arranged on one side of the first column section 21.

Since the column 20 is made up of two relatively rotatable column sections, the column 20 is foldable on its own. At this time, the post 20 may be folded twice. When the stand column 20 is folded once, the stand column 20 rotates around the second rotation axis b and is close to the base 30, so that the length of the stand column 20 in the first direction can be reduced; when folded twice, the second column section 22 rotates around the third rotation axis c, close to the first column section 21, enabling the length of the pillar 20 in the second direction to be reduced.

To ensure that the length of the upright 20 in the second direction can be reduced after rotation of the second column section 22, the direction of extension of the third rotation axis c differs from the second direction.

Optionally, the third rotation axis c is parallel to the second rotation axis b.

For example, in the embodiment shown in fig. 3, 8 and 9, the second rotation axis b and the third rotation axis c are each provided to extend in a direction perpendicular to the paper surface. When the medical trolley is converted from the use state to the folded state, the first column section 21 rotates counterclockwise about the second rotation axis b, and the second column section 22 rotates clockwise about the third rotation axis c. With continued reference to fig. 12, step v, after folding of the post 20 is completed, the second post segment 22 is positioned above the first post segment 21.

In addition, in the embodiment shown in fig. 12, the carrier 10 is provided on the second column section 22; when the second column section 22 is rotated and positioned above the first column section 21, the carrier 10 is positioned above the second column section 22, so that the folding influence of the upright column 20 or the damage to the carrier 10 is avoided.

Alternatively, the third rotation axis c is perpendicular to the extension direction of the first column section 11 and the extension direction of the second rotation axis b.

For example, in the case of the orientation shown in fig. 3, the second rotation axis b is extended in the direction perpendicular to the paper surface, and the third rotation axis c is extended in the up-down direction. When the medical trolley is converted from the use state to the folded state, the first column section 21 rotates counterclockwise, topples left, and the second column section 22 rotates forward or backward, so that the second column section 22 is on the front side or the rear side of the first column section 21.

The extending direction of the third rotation axis c is not limited in the present application as long as the rotational folding of the second column section 22 does not interfere with the rotational folding of the first column section 21 with respect to the base 30.

Alternatively, the first column section 21 and the second column section 22 are connected by a hinge, and the third rotation axis c is a movable axis of the hinge.

Optionally, the first column section 21 and the second column section 22 are connected by a third rotational connection assembly 60.

Specifically, the third rotary joint assembly 60 includes: a first end block 61 connected to the first column section 21; a second end block 62 connected to the second column section 22; a third rotation shaft 63 connecting the first end block 61 and the second end block 62, the third rotation shaft c being a central axis of the third rotation shaft 63; a hook 64 and a slot 65, one of the hook 64 and the slot 65 being disposed on the first end block 61 and the other being disposed on the second end block 62; a button 66 connected to the hook 64; a second elastic member 67, one end of the second elastic member 67 is connected to the button 66, and the other end is connected to the first end block 61 or the second end block 62; pressing the button 66, the second elastic member 67 is compressed, and the hook 64 is away from the clamping groove 65, so as to fold the first column section 21 and the second column section 22; releasing the button 66, the second resilient member 67 returns and the hook 64 approaches the catch 65 to secure the first and second pole segments 21, 22.

Wherein the third rotating shaft 63 can be rotatably connected with the first column section 21, and the second column section 22 is fixedly connected with the third rotating shaft 63; alternatively, the third rotating shaft 63 may be fixedly disposed on the first column section 21, and the second column section 22 is rotatably connected to the third rotating shaft 63; alternatively, the first column section 21 and the second column section 22 are both rotatably connected to the third rotation shaft 63. In each of the above three modes, the rotational movement of the first column section 21 and the second column section 22 can be achieved.

To beautify the appearance of the upright 20, in one embodiment, referring to fig. 8 and 9, the inside of the first end block 61 is provided with a movable passage; the second elastic piece 67 is arranged in the movable channel, one end of the second elastic piece 67 is connected with the bottom of the movable channel, and the other end of the second elastic piece 67 is connected with the button 66; one end of the button 66 extends into the movable channel and the other end protrudes out of the movable channel; the hook 64 is disposed on the button 66, and the head of the hook 64 protrudes from the first end block 61 to contact the upper end surface of the second end block 62; the second end block 62 is provided with a hook channel for contacting the lower end surface of the first end block 61; the clamping groove 65 is arranged in the clamping hook channel.

In this embodiment, the movable channel has a guiding function, and when the button 66 is applied and removed, the button 66 moves along the movable channel to drive the hook 64 to reciprocate along the extending direction of the movable channel. Meanwhile, the movable channel can limit the deformation direction of the second elastic piece 67, so that the unification of the movement direction of the clamping hook 64 is further ensured. The extending direction of the hook channel is parallel to the extending direction of the movable channel, and when the first end block 61 contacts the second end block 62, the head of the hook 64 can extend into the hook channel and move along the hook channel to approach or separate from the slot 65.

In this embodiment, referring to fig. 8, when the first and second column sections 21 and 22 are folded, the button 66 is pressed inward, the second elastic member 67 is compressed, and the hook 64 moves from left to right and gradually moves away from the slot 65; after the hook 64 is separated from the slot 65, the second column section 22 rotates clockwise, so that the second column section 22 can be folded. When the first column section 21 and the second column section 22 are converted from the folded state to the use state, the first end block 61 and the second end block 62 can be made to approach each other by rotating the second column section 22 counterclockwise; pressing the button 66 inward again so that the hook 64 extends into the hook channel; after the first end block 61 contacts the second end block 62, the button 66 is released, and the second elastic member 67 is restored, so that the hook 64 is clamped into the clamping groove 65; the second elastic member 67 is always in a compressed state, and the elastic force thereof can press the hook 64, so that the hook 64 is kept in a state of being hooked with the slot 65.

In other embodiments, the post 20 may also include three or even more post segments that further reduce the extension of the post 20 in the second direction by multiple folds.

Optionally, one of the first end block 61 and the second end block 62 is provided with a positioning block 68, and the other is provided with a positioning groove; when the upright 20 is in use, the locating block 68 is in the locating groove.

The positioning block 68 and the positioning groove which are matched with each other are arranged, so that on one hand, the use states of the first column section 21 and the second column section 22 can be calibrated, and dislocation after the first column section 21 and the second column section 22 are connected is avoided; on the other hand, the two column sections can be prevented from relatively shaking in the use state.

Optionally, the first end block 61 and/or the second end block 62 are provided with a buffer block 69; the buffer block 69 can prevent the first end block 61 and the second end block 62 from striking each other when the first column section 21 and the second column section 22 are converted from the folded state to the use state.

The buffer block 69 may be made of flexible materials such as rubber and plastic. A plurality of buffer blocks 69 and a plurality of buffer blocks 69 can be arranged on the first end block 61 and/or the second end block 62 at intervals so as to ensure the buffer effect.

Optionally, one of the first column section 21 and the second column section 22 is provided with a positioning male member 25, and the other is provided with a positioning female member 26; the positioning male member 25 is inserted into the positioning female member 26 when the first and second column sections 21, 22 are in the folded state.

In one embodiment, referring to step v of fig. 12, after post 20 is folded twice, second post segment 22 is positioned above first post segment 21. Thus, after one folding of the upright 20, referring to step iv of fig. 12, both the positioning male member 25 and the positioning female member 26 are located on the upper surface of the column section.

The positioning convex piece 25 and the positioning concave piece 26 which are matched with each other are arranged, so that on one hand, the folding state of the first column section 21 and the second column section 22 can be calibrated, and the dislocation of the first column section 21 and the second column section 22 during folding can be avoided; on the other hand, the two column sections can be prevented from relatively shaking in the folded state.

Further, the medical cart further comprises a pallet 3 for setting the display device 2; the supporting platform 3 is rotatably arranged on the upright post 20; and/or the saddle 3 is arranged at one end of the upright 20 facing away from the base 30 in a liftable manner.

Wherein the display device 2 may be a display screen for connecting to the host device 1, thereby displaying a page of the host device 1 or displaying operation information of a medical instrument connected to the host device 1. For example, in a specific embodiment, the host device 1 is an ultrasonic host, and the display device 2 is capable of displaying a detected screen of the ultrasonic probe.

The display device 2 can be detachably provided on the stand 3, and is installed according to actual use needs. Since the display device 2 is inexpensive and has low functionality, the display device 2 can also be fixedly mounted on the stand 3.

The pallet 3 may be provided on any surface of the upright 20 that is not connected to the carrier 10 and the base 30. At this time, the setting manner of the supporting platform 3 may be similar to that of the carrying platform 10, and detailed description thereof will be omitted.

Alternatively, referring to fig. 1, the pallet 3 is disposed on an end of the upright 20 facing away from the base 30. When the medical trolley is in a use state, the mounting surface of the supporting platform 3 can be in a vertical plane or slightly inclined, so long as the screen of the display device 2 can face an operator, and the operator can conveniently check the medical trolley.

In one embodiment, pallet 3 is coupled to upright 20 by fourth rotational coupling assembly 70; the fourth rotary joint assembly 70 includes: a fourth rotation shaft 71 connecting the column 20 and the pallet 3; a damping spring 72 disposed on the fourth rotating shaft 71 for providing friction damping; so that the stand 3 is rotated about the fourth rotation shaft 71, the inclination of the display apparatus 2 can be adjusted.

When the upright 20 is in use, the extending direction of the fourth rotating shaft 71 is perpendicular to the first direction. For example, in the embodiment shown in fig. 3, the first direction is a vertical direction, and the fourth rotation shaft 71 is extended in a direction perpendicular to the paper surface.

One of the upright post 20 and the supporting platform 3 is rotatably connected with the fourth rotating shaft 71, and the other is fixedly connected with the fourth rotating shaft 71.

By providing the damping spring piece 72 on the fourth rotating shaft 71, when an external force is applied to the supporting stand 3, the supporting stand 3 can be rotated to adjust the inclination of the display device 2; after the external force is removed, the stand 3 can be kept in an adjusted state to facilitate use of the display device 2.

When the cart is folded, the stand 3 is enabled to rotate around the fourth rotating shaft 71 away from the upright post 20, so that the mounting surface of the stand 3 for contacting the display device 2 is enabled to be gradually away from the ground, and therefore the stand 3 or the display device 2 is prevented from being impacted by the ground when the upright post 20 is folded.

In another embodiment, the pallet 3 is connected to the upright 20 by a fifth rotational connection assembly 80; the fifth rotary joint assembly 80 comprises: a first connection part 81 fixedly provided on the column 20; a second connection portion 82 connected to the pallet 3; a damping rotating shaft 83, the second connecting portion 82 being connected to the first connecting portion 81 through the damping rotating shaft 83; so that the stand 3 is rotated about the damping rotation shaft 83, the facing of the display device 2 can be adjusted.

Referring to fig. 3 and 7, the first connection portion 81, the second connection portion 82, and the damper rotation shaft 83 constitute an axial rotation shaft (range). When the upright 20 is in use, the extending direction of the damping pivot shaft 83 is parallel to the first direction. One of the first connection portion 81 and the second connection portion 82 is rotatably connected to the damper rotation shaft 83, and the other is fixedly connected to the damper rotation shaft 83.

When the cart is in a use state, the display equipment 2 is arranged on the supporting platform 3; the operator rotates the stand 3 or the display device 2, and the stand 3 can rotate around the center axis of the damping rotation shaft 83, thereby changing the facing of the display device 2 so that the display device 2 can be seen from different positions or persons at different positions.

The damping rotating shaft 83 can provide friction damping, and when an operator does not rotate the supporting table 3 or the display device 2, the supporting table 3 cannot actively rotate due to the interference of the friction damping, so that the stable operation of the display device 2 is ensured.

To facilitate lifting of the pallet 3, in one embodiment, a lifting channel is provided in the upright 20, and the pallet 3 is connected to the upright 20 by a connecting shaft, which is slidably disposed in the lifting channel and is capable of moving along the lifting channel. By moving the connecting shaft in the lifting channel, the length of the connecting shaft protruding outside the upright post 20 can be adjusted, and further the adjustment of the height of the pallet 3 is achieved.

To facilitate movement of the connecting shaft along the hoistway, in one embodiment, the connecting shaft is coupled to a driving member (e.g., cylinder, electric cylinder) that is capable of driving the connecting shaft to move actively along the hoistway. In another embodiment, one of the connecting shaft and the lifting channel is provided with a protruding part, and the other is provided with a recessed part, so that the protruding part is separated from the recessed part, and the fixed connection between the connecting shaft and the lifting channel can be released, and the position of the connecting shaft is adjusted; after the connecting shaft is adjusted to the required position, the protruding piece enters the corresponding concave piece, and then the connecting shaft and the lifting channel can be fixed again. The application is not limited to the connection mode of the connecting shaft and the lifting channel.

In order to facilitate the arrangement of the upright post 20 and prevent the upright post 20 from separating from the base 30 when being rotated and folded, the base 30 is provided with a mounting groove 33, and the upright post 20 is arranged in the mounting groove 33; a notch 33a is arranged on one side of the mounting groove 33; when the medical trolley is converted from the use state to the folded state, the upright post 20 rotates towards the notch 33a; the notch 33a is capable of supporting the upright 20 when the medical trolley is in the collapsed condition.

The notch 33a can define the direction of rotation and the degree of tipping of the upright 20. For example, referring to fig. 1, a notch 33a is provided on the left side of the mounting groove 33, and when the stand 20 is folded, the stand 20 is made to tilt leftward, gradually approaching the notch 33a; with continued reference to fig. 12, after the upright 20 is folded, the notch 33a can hold the upright 20 so that the upright 20 extends horizontally and can prevent the upright 20 from continuing to rotate; meanwhile, since the notch 33a is higher than the ground, the notch 33a can prevent the upright 20 from contacting or rubbing with the ground after supporting the upright 20, thereby protecting the upright 20.

In addition, the walls of the mounting groove 33 can be reinforced to prevent the upright post 20 from tilting in other directions. For example, when the column 20 is in the use state, a part of the surface of the column 20 is in contact with the wall of the mounting groove 33, and the wall of the groove can support the column 20. Further, after the upright 20 is tilted toward the notch 33a, at least a part of the upright 20 is received in the mounting groove 33, and the mounting groove 33 can protect the connection portion between the upright 20 and the base 30 from being damaged due to external force after folding.

Further, the base 30 includes: a connecting portion on which the mounting groove 33 is provided; two first legs 34, two first legs 34 are respectively arranged at two ends of the notch 33a in the extending direction; at least one second leg 35 spaced apart from the first leg 34 on the connection portion; the first leg 34 and the second leg 35 are each provided with a mover 31.

Wherein, the two first legs 34 are disposed at intervals, and the upright 20 is located between the two first legs 34 after the upright 20 is folded, and referring to fig. 1, the two first legs 34 can protect the upright 20. At the same time, the design of the first leg 34 also balances the center of gravity of the base 30, avoiding overturning of the cart due to forward shifting of the center of gravity of the cart when the upright 20 is tipped.

Optionally, the extending direction of the first feet 34 intersects the second direction, and the two first feet 34 are symmetrically disposed, so that the base 30 is more stable.

Wherein the second leg 35 can assist the first leg 34 in supporting the connection, thereby improving the stability of the base 30.

Optionally, the base 30 includes two second legs 35, the extending direction of the second legs 35 intersects the second direction, and the two second legs 35 are symmetrically disposed. Further, the first foot 34 and the second foot 35 are in one-to-one correspondence; in the corresponding pair of the first leg 34 and the second leg 35, the moving member 31 on the first leg 34 and the moving member 31 on the second leg 35 are arranged at intervals along the second direction, which is beneficial to improving the stability of the movement of the cart.

Optionally, the base 30 further includes a support bar 36 disposed between the two first legs 34; the support bar 36 is provided with support grooves spaced apart from the mounting grooves 33 in the second direction. The upright 20 is once folded around the second rotation axis b and then is caught by the support groove and the mounting groove 33. The support groove cooperates with the mounting groove 33 to support the upright post 20, so that the upright post 20 can be prevented from contacting the ground.

The following details a method for folding the medical cart provided by the application, and referring specifically to fig. 12, steps i-v; in the illustrated embodiment, the medical cart comprises a carrier 10, a column 20, a base 30 and a pallet 3, the column 20 comprising a first column section 21 and a second column section 22; wherein the first rotation axis a, the second rotation axis b, the third rotation axis c, and the fourth rotation axis d (about which the pallet 3 rotates relative to the upright 20) are all disposed extending in a third direction (the third direction is perpendicular to the first plane).

The method comprises the following steps:

referring to steps I and II, the host apparatus 1 is removed, the stage 10 rotates around the first rotation axis a along the needle, and the stage 10 approaches the column 20;

referring to steps ii and iii, the stand 3 is rotated clockwise about the fourth rotation axis d such that the mounting surface of the stand 3 for mounting the display device 2 is disposed horizontally upward;

Referring to steps III and IV, the upright 20 rotates counterclockwise about the second axis of rotation b, adjacent the base 30, with the notch 33a and support bracket of the base 30 holding the first column segment 21;

referring to steps iv and v, the second column section 22 rotates clockwise about the third rotation axis c, the second column section 22 being stacked on the first column section 21;

after the folding is completed, the cart is converted from the use state shown in the step I to the folding state shown in the step V.

The medical trolley provided by the application is movable and foldable; when the trolley is not used, the occupied space of the trolley can be reduced through folding, and the trolley is convenient to store; when in use, the cart can be restored conveniently. Meanwhile, by making the host apparatus 1 detachable, the applicability of the cart can be improved.

The foregoing examples illustrate only a few embodiments of the application, which are described in detail and are not to be construed as limiting the scope of the claims. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the application, which are all within the scope of the application.
