On the basis of the butt joint of the guide limit bracket 300 and the butt joint bracket 400, the position of the main body frame 210 is limited by the contact of the foot cup 230 with the ground, the friction force between the foot cup 230 and the ground can ensure that the main body frame 210 is stably supported at the current position, the butt joint precision between the lifting frame 200 and the main frame 100 can be ensured, and accordingly, the alignment precision between the second equipment and the first equipment is ensured. In addition, the foot cup 230 contacts the ground, so that the main body frame 210 is stably maintained at the current position, and the guiding and limiting bracket 300 and the docking bracket 400 can be maintained at the current state, which is equivalent to positioning the guiding and limiting bracket 300 and the docking bracket 400, so that the guiding and limiting bracket 300 and the docking bracket 400 are maintained in the docked state, the guiding and limiting bracket 300 and the docking bracket 400 are prevented from being separated from each other, and the docked state of the lifting frame 200 and the main frame 100 is maintained.

Referring to fig. 2b, when the lift frame 200 is in a separated state from the main frame 100, the guide limiting bracket 300 is disconnected from the docking bracket 400, and the lift frame 200 may be in a movable state so as to move the lift frame 200 with respect to the main frame 100. At this time, the lifting frame 200 may support the main body frame 210 through the lifting caster mechanism 220, and the lifting frame 200 is moved by the lifting caster mechanism 220. Wherein, by adjusting the height of the lifting caster mechanism 220, the height of the lifting caster mechanism 220 extending below the mounting plate 211 is larger than the height of the foot cup 230 extending below the mounting plate 211, so that the lifting caster mechanism 220 is in a supporting state, and the foot cup 230 is separated from the ground and has a certain distance from the ground.

Referring to fig. 2a or 2b, in some examples, the foot cup 230 may include a screw 231 and a chassis 232, the screw 231 may be, for example, installed on the mounting plate 211 of the main body frame 210, the chassis 232 is connected to an end of the screw 231 facing the ground, that is, the chassis 232 is connected to a bottom end of the screw 231, the foot cup 230 contacts the ground by means of the chassis 232 to achieve a supporting effect on the main body frame 210, and a surface area of a side surface of the chassis 232 facing the ground is generally large, so that a sufficient contact area between the chassis 232 and the ground may be ensured to ensure that the main body frame 210 is supported stably.

The protruding height of the foot cup 230 (the height of the foot cup 230 protruding below the mounting plate 211) can be adjusted by moving the screw 231 along the height direction of the main body frame 210, so that when the guide limit bracket 300 is docked with the docking bracket 400, the chassis 232 of the foot cup 230 is just supported on the ground by adjusting the protruding height of the foot cup 230, so as to fix the lifting frame 200 at the current docking position, and ensure that the lifting frame 200 is docked stably and firmly with the main frame 100.

The caster group 221 is movably installed on the installation plate 211, the caster group 221 is used for being supported on the ground, and the support frame is driven to move through the caster group 221; and, the caster group 221 is movable in the height direction of the main body frame 210 to adjust the protruding height of the caster group 221, thereby adjusting the height of the lift frame 200 and enabling the switching of the lift caster mechanism 220 between the retracted state and the supporting state. The synchronous lifting structure 222 is connected with each of the caster groups 221, and drives each of the caster groups 221 to synchronously lift through the synchronous lifting structure 222 so as to adjust the extending height of each of the caster groups 221, keep the extending height of each of the caster groups 221 consistent, and ensure that the lifting caster mechanism 220 supports the main body frame 210 stably.

Wherein, by providing at least two caster groups 221, different caster groups 221 are mounted at different positions of the mounting plate 211 to ensure stable support of the main body frame 210.

By arranging at least two caster groups 221 to support different areas of the main body frame 210, the main body frame 210 can be stably supported, the synchronous lifting structure 222 is only connected with each caster group 221, and can drive each caster group 221 to synchronously lift, and each caster 2211 of each caster group 221 can synchronously lift through a connecting plate 2213.

The washer 22213d is sleeved outside the screw rod 22211, and the washer 22213d may be arranged on the first transmission member 22214 and is mainly used for limiting the first transmission member 22214. The portion of the lead screw 22211 sleeved with the first transmission member 22214 may be, for example, a reducing portion, the diameter of the lead screw 22211 below the reducing portion is smaller than the diameter of the lead screw 22211 above the reducing portion, the lead screw 22211 forms a step surface at the reducing portion, the first transmission member 22214 may be sleeved from the bottom end of the lead screw 22211 and abut against the step surface, and the gasket 22213d abuts against the other end of the first transmission member 22214 to limit the first transmission member 22214.

As shown in connection with fig. 3 and 4, for the transmission assembly 2222 driving each of the lifting assemblies 2221, as one embodiment, the transmission assembly 2222 may include a transmission shaft 22221, a driving element 22222, and at least two second transmission elements 22223. The driving element 22222 is connected to the driving shaft 22221, and drives the driving shaft 22221 to rotate through the driving element 22222. The transmission shaft 22221 spans across each lifting assembly 2221 to enable each lifting assembly 2221 to be driven simultaneously, so that each lifting assembly 2221 remains synchronously movable. The second transmission members 22223 are connected to the transmission shaft 22221, for example, the second transmission members 22223 may be sleeved on the transmission shaft 22221, each second transmission member 22223 is set in a one-to-one correspondence with each lifting assembly 2221, the second transmission members 22223 correspond to the first transmission members 22214 of the lifting assemblies 2221 and are in transmission connection with the first transmission members 22214, and the power generated by the rotation of the transmission shaft 22221 is transmitted to each screw rod 22211 through the cooperation of each second transmission member 22223 and each first transmission member 22214, so as to realize synchronous movement of each lifting assembly 2221.

For the mounting and fixing of the transmission shaft 22221, referring to fig. 3, in some embodiments, fixing bases d may be mounted on the mounting plate 211 of the main body frame 210, for example, two fixing bases d may be provided at intervals along the extending direction of the transmission shaft 22221, and the transmission shaft 22221 passes through each fixing base d to fix the transmission shaft 22221 on the mounting plate 211. And, still can install bearing e between transmission shaft 22221 and the fixing base d, bearing e can realize the relative rotation between transmission shaft 22221 and the fixing base d, ensures that transmission shaft 22221 rotates smoothly under the drive of driver 22222.

For example, the driving member 22222 for driving the transmission shaft 22221 to rotate may be a rocking bar 22222a, and the rocking bar 22222a may be installed at an end of the transmission shaft 22221, for example, to drive the transmission shaft 22221 to rotate by manually rotating the rocking bar 22222 a. Since the frequency of switching the lifting frame 200 between the fixed state and the movable state is relatively low, the lifting caster mechanism 220 does not need to be frequently switched between the retracted state and the supporting state, and thus, the requirement can be satisfied by manually rotating the rocking lever 22222a, and the cost is low. Of course, in other examples, a motor may be used as the driving element 22222 to drive the rotation shaft to rotate, so as to save labor, which is not particularly limited in this embodiment.

Referring to fig. 4, as a specific example, the first transmission member 22214 sleeved on the screw rod 22211 may be a worm wheel 22214a, and the second transmission member 22223 connected to the transmission shaft 22221 may be a worm 22223a, with the worm 22223a being engaged with the worm wheel 22214 a.

The worm 22223a may be a separately machined structural member, and the worm 22223a may be connected to the transmission shaft 22221 by means of adhesion, welding, mechanical locking, or the like; alternatively, the worm 22223a may be integrally formed with the transmission shaft 22221, and the worm 22223a may be formed by machining spiral teeth that match the worm wheel 22214a on the outer wall surface of the transmission shaft 22221.

It should be understood that, in addition to the above-mentioned manner of providing the transmission shaft 22221 and cooperating with the worm wheel 22214a via the worm 22223a to transmit power to the screw 22211, other manners of driving each of the caster groups 221 to move up and down synchronously may be adopted. For example, the lifting assembly 2221 may also adopt a transmission structure such as a linear module or a hydraulic transmission module to replace the transmission of the screw rod 22211, and synchronous movement is realized by means of belt transmission, transmission of the transmission shaft 22221, or control of the control unit between the linear modules or the hydraulic transmission modules.

Referring to fig. 7, when the guide limiting bracket 300 is docked with the docking bracket 400, the guide rod 410 of the docking bracket 400 extends to the guide assembly 310 of the guide limiting bracket 300, and the guide rod 410 extends into the guide assembly 310 and docks with the guide assembly 310 by virtue of the guiding function of the guide assembly 310 on the guide rod 410, so that the docking of the guide limiting bracket 300 with the docking bracket 400 is realized.

The guiding and limiting bracket 300 may be provided with a guiding component 310, and correspondingly, the docking bracket 400 is provided with a guiding rod 410, and the docking of the guiding and limiting bracket 300 and the docking bracket 400 is realized by means of the cooperation of the guiding rod 410 and the guiding component 310. Or, the guiding and limiting bracket 300 may be provided with more than two guiding components 310, and corresponding to the guiding and limiting bracket 300, the docking bracket 400 may be provided with more than two guiding rods 410, and the guiding rods 410 are in one-to-one docking with the guiding components 310, so as to realize docking between the guiding and limiting bracket 300 and the docking bracket 400, thereby improving docking accuracy between the guiding and limiting bracket 300 and the docking bracket 400, and also maintaining the docking state more stably. As an example, referring to fig. 5-7, the guide limiting bracket 300 is shown to be provided with two guide assemblies 310, and the docking bracket 400 is correspondingly provided with two guide bars 410.

In the case that the guide limit bracket 300 includes more than two guide assemblies 310, each guide assembly 310 of the guide limit bracket 300 may be independently mounted on a corresponding frame (the main frame 100 or the elevating frame 200), or each guide assembly 310 may be mounted on a base member through which each guide assembly 310 is mounted on a corresponding frame to form an integral structure. For example, the guide assemblies 310 may be mounted on top of the respective racks.

In order to facilitate assembly and disassembly of the docking bracket 400, the docking bracket 400 may be provided with a connection plate 420, each guide bar 410 may be mounted to the connection plate 420 such that the docking bracket 400 forms an integral structure, the docking bracket 400 may be mounted to a corresponding frame (the lifting frame 200 or the main frame 100) through the connection plate 420, for example, the connection plate 420 may be disposed near one side of the corresponding frame, one end of the guide bar 410 is connected to the connection plate 420, and the other end of the guide bar 410 extends out of the frame, in other words, the guide bar 410 extends to the guide assembly 310 mounted on the other frame. For example, the docking cradle 400 may be mounted on top of a corresponding rack.

Referring to fig. 5 to 7, the guide assembly 310 may include a guide sleeve 311, and one end of the guide sleeve 311 facing the guide bar 410 is a socket 3111 thereof, in other words, when the lifting frame 200 is docked with the main frame 100, the guide bar 410 of the docking bracket 400 is located at the side of the socket 3111 of the guide sleeve 311, and the guide bar 410 is inserted into the guide sleeve 311, so as to achieve docking of the docking bracket 400 with the guide limiting bracket 300. Wherein, the other end of the guide sleeve 311 opposite to the socket 3111 thereof is a closed end, when the lifting frame 200 is docked with the main frame 100, the guide rod 410 extends into the guide sleeve 311 from the socket 3111 of the guide sleeve 311, and the guide rod 410 continuously moves toward the closed end of the guide sleeve 311 under the guiding action of the guide sleeve 311 until the end of the guide rod 410 is abutted with the closed end of the guide sleeve 311, and the horizontal position of the lifting frame 200 relative to the lifting frame 200 is positioned when docking.

For example, referring to fig. 5, the closed end of the guide sleeve 311 may be provided with a cushion 3112, and the cushion 3112 may be, for example, a rubber layer, a silicone layer, or a foam layer, which may be adhered to the inner sidewall of the closed end of the guide sleeve 311. Through the cushioning effect of blotter 3112, avoid guide bar 410 to strike the blind end of collision uide bushing 311, reduce the effort that produces when guide bar 410 and uide bushing 311 contact, help preventing that the blind end of uide bushing 311 from producing the deformation, in long-term use, guarantee the accuracy of docking between guide limit bracket 300 and the docking bracket 400.

In addition, a position switch 340 may be further disposed on the guiding limit bracket 300, the position switch 340 may be mounted on the guiding sleeve 311, and the position switch 340 may be located at the closed end of the guiding sleeve 311, where the position switch 340 is, for example, a photoelectric switch, and the position of the guiding rod 410 is detected by the position switch 340. Referring to fig. 5 to 7, in the case that the guide rod 410 extends into the guide sleeve 311 to be in butt joint with the guide sleeve, it is inconvenient to observe the extending position of the guide rod 410 from the outside, and by arranging the photoelectric switch, it can help to determine whether the guide rod 410 moves in place, ensure that the guide rod 410 abuts against the closed end of the guide sleeve 311, and ensure that the guide limiting bracket 300 is in butt joint with the butt joint bracket 400.

In addition, in order to facilitate the docking of the guide rod 410 with the guide sleeve 311, referring to fig. 5, in some embodiments, the guide sleeve 311 may be designed to be slightly larger in size, and the width between the two side walls of the guide sleeve 311 may be larger than the diameter of the guide rod 410, so that the guide rod 410 may be inserted into the guide sleeve 311 even in the case that there is a slight misalignment between the central axis of the guide sleeve 311 and the central axis of the guide sleeve 311, thereby reducing the docking difficulty of the guide rod 410 and the guide sleeve 311.

Meanwhile, in order to ensure the docking accuracy between the guiding and limiting bracket 300 and the docking bracket 400, one side of the guiding sleeve 311 facing the ground may be set as an open side, the guiding seat 312 is set on the open side of the guiding sleeve 311, the guiding groove 3121 is set on one side of the guiding seat 312 facing the guiding sleeve 311, the guiding seat 312 and the guiding sleeve 311 cooperate together to guide the guiding rod 410, so as to realize the docking of the docking bracket 400 and the guiding and limiting bracket 300. Referring to fig. 7, a part of the guide bar 410 is positioned in the guide groove 3121 of the guide sleeve 311, and the guide bar 410 moves along the guide groove 3121 to precisely guide the guide bar 410, thereby precisely aligning the lifting frame 200 with the main frame 100.

In addition, for the guide holder 312 installed below the guide sleeve 311, a certain gap inevitably exists between the guide holder 312 and the guide sleeve 311, so that the space enclosed by the guide holder 312 and the guide sleeve 311 is large, the movable space of the guide rod 410 is increased, especially the movable space of the guide rod 410 in the vertical direction, and enough lifting space can be reserved for switching the lifting caster mechanism 220 of the lifting frame 200 between the supporting state and the recovering state.

For the frame of the frame structure, in order to install the guide holder 312, in some embodiments, the guide limiting support 300 may further include a support holder 320, where the support holder 320 is located on an open side of the guide sleeve 311, and the support holder 320 may be installed on a side wall of the frame, for example, and the guide holder 312 may be connected to the support holder 320, and support and fix the guide holder 312 through the support holder 320. For the case that the guiding and limiting support 300 comprises more than two guiding seats 312, the guiding and limiting support 300 is convenient to assemble and disassemble by connecting each guiding seat 312 on the supporting seat 320. In addition, the supporting seat 320 can also be used as a mounting base for other components of the guiding limit bracket 300. Illustratively, the guide holder 312 may be attached to the top end of the support holder 320.

When the lifting frame 200 is aligned with the main frame 100, the guide rod 410 of the docking bracket 400 extends into the guide sleeve 311 from the insertion opening 3111 of the guide sleeve 311 of the guide limit bracket 300, and continuously moves toward the closed end of the guide sleeve 311 under the guiding action of the guide groove 3121 on the guide seat 312 until the guide rod 410 moves to abut against the closed end of the guide sleeve 311, so as to position the horizontal position of the lifting frame 200, then, by adjusting the extending height of each foot cup 230, the main frame 210 of the lifting frame 200 is supported by each foot cup 230, the extending height of the lifting caster mechanism 220 is adjusted to be switched to the recovery state, and by adjusting the extending height of each foot cup 230, the height of the lifting frame 200 is adjusted to a predetermined height (for example, the top of the lifting frame 200 is flush with the top of the main frame 100), so as to realize docking of the lifting frame 200 with the main frame 100.

In some embodiments, on the basis that the guide rod 410 of the docking bracket 400 abuts against the guide sleeve 311 of the guide limiting bracket 300 and supports the main body frame 210 of the lifting frame 200 by using the foot cup 230, the guide limiting bracket 300 and the docking bracket 400 may be fixedly connected together, so that the lifting frame 200 and the main frame 100 are securely docked to prevent the offset therebetween. As an example, as shown in fig. 5 and 6, a first positioning hole 412 may be provided on the guide rod 410, a second positioning hole 3122 may be provided on the guide seat 312, when the guide rod 410 abuts against the closed end of the guide sleeve 311, the first positioning hole 412 coincides with the second positioning hole 3122, and the guide rod 410 and the guide sleeve 311 are fixedly connected together by penetrating locking members such as screws, bolts, etc. in the first positioning hole 412 and the second positioning hole 3122, so as to realize the fixed connection of the docking bracket 400 and the guide limiting bracket 300. Wherein, the guide sleeve 311 can be provided with an avoidance hole 3113, the second positioning hole 3122 on the guide seat 312 is exposed in the avoidance hole 3113, the avoidance hole 3113 provides an avoidance space for installing the locking member, and is convenient for the operation of the operator.

With continued reference to fig. 5, in order to improve the accuracy of the docking between the lifting frame 200 and the main frame 100, the guide limit bracket 300 may further include a limit assembly 330, and referring to fig. 6, a limit slot 411 may be provided on the guide rod 410, and the limit slot 411 may be located, for example, on a side of the guide rod 410 facing the ground, and the position of the guide rod 410 in the axial direction thereof may be defined by the cooperation of the limit assembly 330 and the limit slot 411. The guide bar 410 completely limits the axial direction by virtue of the abutting of the end part of the guide bar 410 and the guide sleeve 311 and the matching of the limit slot 411 and the limit assembly 330, so that the guide bar 410 can be prevented from shaking back and forth along the axial direction.

Wherein, the limiting component 330 may include a limiting shaft 331 and a pushing component 332, the limiting shaft 331 is used for being clamped into the limiting slot 411 of the guide rod 410, limiting the guide rod 410, and the pushing component 332 is used for providing an acting force, so that the limiting shaft 331 is firmly clamped in the limiting slot 411. For example, the limiting shaft 331 may be located at a side of the guide holder 312, and the limiting shaft 331 and the guide sleeve 311 are staggered with each other, in other words, the extending direction of the limiting shaft 331 and the extending direction of the guide sleeve 311 are staggered with each other. For the guide rod 410 moving along the extending direction of the guide sleeve 311, the axial direction of the limiting shaft 331 and the axial direction of the guide rod 410 are staggered, for example, the limiting shaft 331 may be perpendicular to the guide rod 410, after the limiting shaft 331 is clamped into the limiting slot 411, the guide rod 410 is prevented from moving in the direction of exiting the guide sleeve 311, and the end of the guide rod 410 is tightly abutted to the guide sleeve 311. The pushing member 332 is connected between the limiting shaft 331 and the supporting seat 320, the pushing member 332 extends, for example, in a vertical direction, the pushing member 332 is a telescopic structure, when the limiting shaft 331 is clamped into the limiting slot 411 of the guide rod 410, the pushing member 332 is in a compressed state, and the acting force generated by the pushing member 332 can enable the limiting shaft 331 to be stably clamped in the limiting slot 411.

Referring to fig. 5, in some embodiments, the support base 320 may be configured to include a support plate 321 and a support 322, where the support plate 321 is mounted to the corresponding frame as a main support structure, the support plate 321 may be configured as a thin plate-shaped member, and in order to firmly mount the pushing member 332, the support 322 is mounted on a side of the support plate 321 facing the limiting shaft 331, and the pushing member 332 is connected to the support 322.

In some examples, the pushing member 332 may be an elastic member, for example, the pushing member 332 is a spring, two ends of the elastic member are respectively connected with the limiting shaft 331 and the support 322, and when the limiting shaft 331 is clamped in the limiting slot 411 of the guide rod 410, the elastic member is in a compressed state, and the elastic force of the elastic member can enable the limiting shaft 331 to be stably clamped in the limiting slot 411. In other examples, the pushing member 332 connected between the limiting shaft 331 and the support 322 may be a cylinder, the cylinder drives the limiting shaft 331 to move by means of movement of a piston rod, and at the same time, the piston rod moves to compress the gas in the cylinder barrel of the cylinder, and the acting force generated by the compression of the gas is utilized to make the limiting shaft 331 stable in the early-clamping limiting slot 411.

With continued reference to fig. 5, taking the pushing member 332 as an elastic member as an example, since the deformation directionality of the elastic member is not fixed, in order to make the limiting shaft 331 stably move, in this embodiment, the limiting assembly 330 may further include a linear guide 333, the linear guide 333 may be mounted on the supporting plate 321, the limiting shaft 331 is connected with the linear guide 333, and the track of the vertical movement of the limiting shaft 331 is limited by means of the linear guide 333, so that the limiting shaft 331 always moves along the vertical direction, ensuring that the limiting shaft 331 can be smoothly clamped into the limiting slot 411 of the guide rod 410, and limiting the expansion direction of the elastic member, thereby being beneficial to prolonging the service life of the elastic member. In addition, a blocking piece f may be installed on the supporting plate 321 (for example, the bottom end of the supporting plate 321), where the blocking piece f may be located at the bottom end of the linear guide 333, and the blocking piece f is used to limit the movement limit position of the linear guide 333, so as to ensure the stable operation of the linear guide 333.

As for the connection between the limiting shaft 331 and the linear guide 333, the limiting assembly 330 may further be provided with a fixing plate 334 for supporting the limiting shaft 331, the fixing plate 334 may be disposed in parallel with the supporting plate 321, for example, the limiting shaft 331 may be connected to the top end of the fixing plate 334, and the linear guide 333 is connected between the fixing plate 334 and the supporting plate 321. On the one hand, the contact area between the fixed plate 334 and the linear guide 333 is larger, the linear guide 333 can stably drive the fixed plate 334 to move, so as to ensure the stable movement of the limiting shaft 331; on the other hand, the fixing plate 334 provides a suitable moving space for the limiting shaft 331 through its height, which is beneficial to the cooperation between the limiting shaft 331 and the guide rod 410.

Fig. 8-11 are schematic views illustrating a process of primary docking of a lifting frame with a main frame according to an embodiment of the present application. Referring to fig. 8 to 11, for the case where the docking or separation with the main frame 100 is achieved mainly by moving the elevation frame 200, the guide limit bracket 300 may be installed to the main frame 100, the docking bracket 400 may be installed to the elevation frame 200, and when the elevation frame 200 is docked or separated with the main frame 100, the guide limit bracket 300 installed to the main frame 100 remains stationary, and the guide bar 410 on the docking bracket 400 is inserted into or withdrawn from the guide bush 311 of the guide limit bracket 300 along with the movement of the elevation frame 200, so that the elevation frame 200 corresponds to the main frame 100. In addition, for the first device that can be used independently from the second device, the guide limiting bracket 300 may be mounted on the main frame 100 in a non-exposed manner, and also may enhance the appearance effect of the main frame 100.

Therefore, in this embodiment, the guide and stopper bracket 300 is attached to the main frame 100, and the docking bracket 400 is attached to the lifter frame 200. It should be noted that in other embodiments, the guide limiting bracket 300 may be mounted on the lifting frame 200, and the docking bracket 400 may be mounted on the main frame 100.

Referring to fig. 8 (a), before the lifting frame 200 is initially docked with the main frame 100, the foot cup 230 of the lifting frame 200 is separated from the ground, and the lifting caster mechanism 220 is in a supporting state to support the main frame 210, so that the lifting frame 200 can be moved to the position of the main frame 100. Meanwhile, it is necessary to adjust the height of the elevating frame 200 to a proper position, and the height of the elevating frame 200 may be adjusted by shaking the rocking bar 22222a, as shown in fig. 8 (b), at this time, the top side of the guide bar 410 of the docking bracket 400 is lower than the top of the guide sleeve 311 of the guide limit bracket 300, so that the guide bar 410 may be protruded into the guide sleeve 311, and the bottom side of the guide bar 410 is higher than the top side of the limit shaft 331.

As shown in fig. 9 (a), the lifter frame 200 is pushed to a predetermined position, and as shown in fig. 9 (b), at this time, the guide rod 410 of the docking bracket 400 is abutted to the cushion pad 3112 of the closed end of the guide sleeve 311 of the guide stopper assembly 330.

Referring to fig. 10 (a), after that, the rocker 22222a is rocked to gradually decrease the protruding height of the casters 2211 of the lifting caster mechanism 220, and the height of the lifting frame 200 is lowered. As shown in fig. 7 and 10 (b), the guide bar 410 of the docking bracket 400 is supported on the guide seat 312 of the guide limit bracket 300, and the left and right positions of the guide bar 410 in the radial direction thereof are defined by the groove walls on both sides of the guide groove 3121 of the guide seat 312; and, the limiting shaft 331 of the guiding limiting bracket 300 is clamped into the limiting slot 411 of the guiding rod 410, the limiting shaft 331 abuts against the guiding rod 410 by means of the elastic force of the elastic piece, and the front and rear positions of the guiding rod 410 in the axial direction are limited by the combined action of the buffer pad 3112 at the closed end of the guiding sleeve 311 and the limiting shaft 331, so that the butt joint of the butt joint bracket 400 and the guiding limiting bracket 300 is realized.

Referring to fig. 11 (a), after the position of the elevating rack 200 is determined by the butt joint of the butt joint bracket 400 and the guide limit bracket 300, the foot cup 230 is lowered to contact the ground by adjusting the protruding height of the foot cup 230, and the protruding height of each foot cup 230 is adjusted to be uniform, and the body frame 210 of the elevating rack 200 is supported by the foot cup 230; referring to fig. 11 (b), the rocker 22222a is rocked to gradually raise the caster 2211, and the lifting caster mechanism 220 is brought into a retracted state.

The above completes the primary docking of the lift frame 200 and the main frame 100, and determines the protruding height of the foot cup 230 when the lift frame 200 is in the docked state.

Fig. 12-15 are schematic diagrams illustrating a process of moving the lifting frame out to reset according to an embodiment of the present application. Referring to fig. 12 to 15, after the initial docking determines the protruding height of the cup 230, the subsequent lifting frame 200 is separated from the main frame 100 and then docked, so that it is unnecessary to adjust the height of the cup 230.

Specifically, referring to fig. 12 (a), by rocking the rocking lever 22222a, the lifting caster mechanism 220 is converted into a supporting state, the lifting frame 200 is lifted, and the footcup 230 is separated from the ground; referring to fig. 12 (b), the bottom side of the guide bar 410 of the docking bracket 400 is made higher than the top side of the limit shaft 331, and the top side of the guide bar 410 is made lower than the top of the guide sleeve 311 of the guide limit bracket 300.

Referring to fig. 13, the lift frame 200 is pulled in a direction away from the main frame 100, so that the docking bracket 400 is separated from the guide limit bracket 300, and the lift frame 200 is separated from the main frame 100.

When the lifter frame 200 is separated from the main frame 100 and then the lifter frame 200 is reset to be docked with the main frame 100, as shown in fig. 14 (a), the lifter frame 200 is moved to a predetermined docking position with the main frame 100, as shown in fig. 14 (b), and at this time, the end of the guide rod 410 of the docking bracket 400 on the lifter frame 200 is abutted against the cushion pad 3112 at the closed end of the guide sleeve 311 of the guide stopper bracket 300 on the main frame 100. Referring to fig. 15, since the footcup 230 is at a predetermined height required for docking, only the rocker 22222a is required to be rocked to raise the caster 2211, and the lifting caster mechanism 220 is gradually lifted up to a retracted state, so that the footcup 230 contacts the ground and supports the main body frame 210 of the lifting frame 200, i.e., the resetting of the lifting frame 200 is completed.
