Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of conference machine, in particular to a conference machine capable of quick disassembly and quick assembly. BACKGROUND

[0002] The conference machine is composed of a display screen, a middle frame, a back plate and an imaging electronic module installed in the middle frame when the display screen is installed in front of the middle frame, etc. The conference machine is usually hung in the visual range by the suspension structure on the back side of the back plate, similar to a television or a display for displaying conference content.

[0003] The back plate of the conference machine is fixed on the back side of the middle frame by buckles or screw docking. When the internal electronic module of the conference machine is maintained, the latter is not easy to disassemble. Although the buckle type is convenient for disassembling the back plate from the middle frame, in order to improve the strength of the connection between the back plate and the middle frame, multiple buckle structures are often arranged in the contour range of the middle frame. When disassembling, these buckles need to be removed one by one. When disassembling, the maintenance is completed after disassembling, and when reassembling, the disassembly and assembly efficiency is low. In particular, the disassembled middle frame cannot be placed vertically on the workbench, causing inconvenience in operation when some special elements in the middle frame are disassembled or maintained with the display screen. SUMMARY

[0004] The technical problem to be solved by the present application is that by setting a single-station operating area, the conference machine shell can be disassembled or reassembled, improving the disassembly and assembly efficiency.

[0005] The technical solution of this invention is a quick-release and quick-install conference machine, comprising a middle frame that is open at the front and back and a back panel disposed on the rear side of the middle frame. The left side of the inner cavity of the middle frame has two upper and lower movable first locking blocks, and the right side of the inner cavity of the middle frame has two upper and lower movable second locking blocks. The left front side of the back panel has two upper and lower first locking frames, and the right front side of the back panel has two upper and lower second locking frames. When the back panel is fixed to the rear side of the middle frame, the first locking frames enter the left side of the inner cavity of the middle frame and are locked by the relative movement of the two upper and lower first locking blocks. Simultaneously, the second locking frames enter the right side of the inner cavity of the middle frame and are locked by the relative movement of the two upper and lower second locking blocks. A space is provided between the two first locking blocks on the left side. The system includes a first linkage assembly and a second linkage assembly located between the two second locking blocks on the right side. A first rack plate is connected to the first linkage assembly, and a second rack plate is connected to the second linkage assembly. A carrier plate is located in the middle of the frame, and a gear is mounted on the carrier plate. The first and second rack plates are symmetrically meshed on the upper and lower sides of the gear. A pull plate is connected to the second rack plate. When the pull plate moves the second rack plate to the left, it causes the second linkage assembly to fold. Simultaneously, the pull plate also meshes with the gear to rotate counterclockwise, causing the first rack plate to move to the right and the first linkage assembly to fold. A limiting hole is provided on the pull plate.

[0006] When the first link assembly and the second link assembly are folded, they simultaneously cause the upper and lower first locking blocks and the upper and lower second locking blocks to separate from the first locking frame and the second locking frame, respectively.

[0007] A supporting assembly is provided below the middle frame. The supporting assembly includes a supporting frame hinged to the lower part of the middle frame and a driving rod slidably engaged with the carrier plate. There are two supporting frames, which are symmetrical on both sides of the carrier plate. The top end of the driving rod is connected to the first rack plate. The top ends of the two supporting frames are hinged to the bottom end of the driving rod. When the driving rod moves left and right with the first rack plate, it slides on the carrier plate and moves up and down. When the driving rod moves up and down, it simultaneously drives the two supporting frames to move up and down reciprocally at the bottom of the middle frame and inside the middle frame.

[0008] The left end of the middle frame has an operating hole located on the linear movement path of the pull plate, and the bottom center of the middle frame has a movable groove located on the lifting path of the auxiliary support frame.

[0009] As a further preferred, the first connecting rod assembly comprises two first connecting rods, one end of each of which is hingedly connected to the upper and lower first lock blocks, and a first hinge shaft that hingedly connects the other ends of the two first connecting rods together. The second connecting rod assembly comprises two second connecting rods, one end of each of which is hingedly connected to the upper and lower second lock blocks, and a second hinge shaft that hingedly connects the other ends of the two second connecting rods together. One end of the first rack plate is engaged with the bottom side of the gear through the engagement surface, and the other end of the first rack plate is provided with a connection outside the common hingedly connected end of the two first connecting rods through the first hinge shaft. One end of the second rack plate is engaged with the top and bottom sides of the gear through the engagement surface, and the other end of the second rack plate is provided with a connection outside the common hingedly connected end of the two second connecting rods through the second hinge shaft.

[0010] As a further preferred, the left end of the inner cavity of the middle frame is provided with a first connecting plate, and the middle part of the right end of the inner side of the middle frame is provided with a second connecting plate. The first connecting plate and the second connecting plate are both provided with a slot. The first hinge shaft is slidingly fitted in the slot on the first connecting plate, and the second hinge shaft is slidingly fitted in the slot on the second connecting plate. The slots on the first connecting plate and the second connecting plate are on the same straight line.

[0011] As a further preferred, the front end of the first hinge shaft is provided with a first roller shaft that rolls on the front side surface of the first connecting plate, and the front end of the second hinge shaft is provided with a second roller shaft that rolls on the front side surface of the second connecting plate.

[0012] As a further preferred, an operation space is left between the first connecting plate and the second connecting plate.

[0013] As a further preferred, a folding rod is provided in the operation hole, the folding rod is connected to the pull plate through a damping shaft, and the folding rod is folded in the operation hole.

[0014] As a further preferred, the same size springs are provided between the first lock block, the second lock block, and the inner side wall of the middle frame, and the middle frame is provided with a track for smooth sliding of the first lock block and the second lock block.

[0015] As further preferred, the auxiliary supporting assembly further comprises a bridging assembly, the bridging assembly comprises a rotating seat adapted on the carrier plate and a cam provided on the rotating seat, the rotating seat is located between the top end of the driving rod and the bottom of the first rack plate, the bridging assembly further comprises a rubber sheet fixed on the bottom surface of the first rack plate, the outer surface of the rotating seat rolls on the bottom surface of the rubber sheet, the top end of the driving rod is provided with a rubber sleeve, the rubber sleeve is provided with a rounded corner located on the rotating track of the cam, and the auxiliary supporting assembly further comprises a connecting rod structure connected to the bottom end of the driving rod and the two auxiliary supporting frames.

[0016] The present application has the following beneficial effects compared with the prior art,

[0017] The first and second connecting rod assemblies are used as synchronous folding components, so that the plurality of lock racks in the middle frame can be quickly removed or locked from the back plate. The first rack plate is connected to the first connecting rod assembly, the second rack plate is connected to the second connecting rod assembly, and the carrier plate is arranged in the middle of the middle frame. The carrier plate is provided with a gear. When the pull plate drives the second rack plate to move leftward, the second connecting rod assembly can be folded. When the pull plate drives the second rack plate to move leftward, the gear can also be rotated counterclockwise, and the first rack plate can be driven to move rightward by the gear, and the first connecting rod assembly can be folded at the same time. When the pull plate is pulled outward, the pull plate can drive the second rack plate to move outward, and the tooth surface of the second rack plate can mesh with the gear to rotate counterclockwise. When the gear rotates counterclockwise, the first rack plate and the second rack plate can be synchronously linearly moved in opposite directions. Since the second rack plate and the first rack plate move synchronously, the two first connecting rods of the first connecting rod assembly and the two second connecting rods of the second connecting rod assembly can be folded, respectively. When the two first connecting rods are folded, the first lock blocks at the ends of the two first connecting rods can move relative to each other. The two second connecting rods that are synchronously folded with the first connecting rod can drive the second lock blocks at the ends of the two second connecting rods to move relative to each other. Therefore, the two first lock blocks and the two second lock blocks can be separated from the first lock racks and the second lock racks on the inner sides of the back plate, respectively. The first lock racks and the second lock racks are no longer limited by the first lock blocks and the second lock blocks. Therefore, the back plate can be quickly removed from the middle frame. When operating, the operator is located on one side of the middle frame, and all the buckle structures can be disassembled at a single work station, which is convenient for operation.

DETAILED DESCRIPTION

[0027] The above and other embodiments and advantages of the present application are described in detail by referring to the attached drawings, in which:

[0028] In an embodiment, as shown in Figures 1-8 .

[0029] This embodiment provides a quick-release and quick-install conference machine, which includes a middle frame 1 that is connected from front to back and a back panel 2 disposed on the rear side of the middle frame 1. The front side of the middle frame 1 is used to install the display screen of the conference machine, and the rear side is used to install the back panel 2. In actual assembly, a hook is set on the back of the back panel 2 to hang the conference machine in the visible range. When disassembling and maintaining, the back panel 2 needs to be removed from the rear side of the middle frame 1, leaving only the display screen on the front side of the middle frame 1.

[0030] To enable the removal of the back panel 2 from the rear of the middle frame 1 to be completed from only one operating point, achieving quick removal and quick reassembly, the structure of the middle frame 1 has been improved in this embodiment as follows:

[0031] First, two first locking blocks 5 are located on the left side of the inner cavity of the middle frame 1, and two second locking blocks 6 are located on the right side of the inner cavity of the middle frame 1. Two first locking frames 7 are located on the left front side of the back panel 2, and two second locking frames 8 are located on the right front side of the back panel 2. The two first locking blocks 5 on the left and the two second locking blocks 6 on the right serve as hanging components within the middle frame 1. During assembly, the back panel 2 is quickly assembled onto the middle frame 1, and during maintenance, it is used to quickly remove the back panel 2 from the middle frame 1. Therefore, a first locking frame 7 is provided on the front side of the back panel 2 facing the first locking blocks 5 and the second locking blocks 6, forming a hook-and-mount assembly with the first locking blocks 5. Similarly, a first locking frame 7 is also provided to form a hook-and-mount assembly with the second locking blocks 6. This allows the first locking frame 7 to enter the left side of the inner cavity of the middle frame 1 and be locked by the first locking blocks 5, while simultaneously allowing the second locking frame 8 to enter the right side of the inner cavity of the middle frame 1 and be locked by the second locking blocks 6.

[0032] The hook-and-attach structure formed by the first locking block 5 and the first locking frame 7, and the snap-fit ​​structure formed by the second locking block 6 and the second locking frame 8, replace the traditional screw fixing method, thereby improving the assembly and disassembly efficiency when the back plate 2 is assembled onto or removed from the middle frame 1.

[0033] Secondly, since the first locking block 5 and the second locking block 6 are located within the middle frame 1, and their engagement and disengagement with the first locking frame 7 and the second locking frame 8 are also achieved within the middle frame 1, this not only affects the appearance quality of the middle frame 1, but also ensures smooth movement of the two first locking blocks 5 relative to or in opposite directions. This is because the first locking blocks 5 and 6 slide within the middle frame 1 via a track, ensuring stability during their relative or opposite movements. When the two second locking blocks 6 move relative to or in opposite directions, the first locking block 5 moves smoothly due to the sliding fit. The first locking block 5 and the second locking block 6 are symmetrically arranged from left to right. The first locking frame 7 and the second locking frame 8 are also symmetrically arranged from left to right. Therefore, it can be ensured that when the two upper and lower first locking blocks 5 on the left side are disengaged or engaged with the two upper and lower first locking frames 7 on the left side of the back plate 2, it can be done synchronously with the two upper and lower second locking blocks 6 on the right side being disengaged or engaged with the two upper and lower first locking frames 7 on the right side. This ensures that the back plate 2 is installed on or removed from the middle frame 1 synchronously and effectively.

[0034] To ensure that the disengagement actions of the upper and lower first locking blocks 5 are synchronized, and also to ensure that the disengagement actions of the upper and lower second locking blocks 6 are synchronized, a power component needs to be installed on the outer side of the middle frame 1. This embodiment provides this power function: a first connecting rod assembly 9 is installed between the upper and lower first locking blocks 5 on the left side, and a second connecting rod assembly 10, symmetrical to the first connecting rod assembly 9, is installed between the two second locking blocks 6 on the right side. The first connecting rod assembly 9 includes two first connecting rods 91, one end of which is respectively hinged to the upper and lower first locking blocks 5, and a first hinge shaft 92 that hinges the other ends of the two first connecting rods 91 together.

[0035] The second linkage assembly 10 includes two second linkages 101, one end of which is respectively hinged to the upper and lower second locking blocks 6, and also includes a second hinge pin 102 that hinges the other ends of the two second linkages 101 together.

[0036] Therefore, in order to disengage the upper and lower first locking frames 7 on the left side of the back panel 2 from the upper and lower first locking blocks 5 on the left side of the middle frame 1, the operator only needs to apply a pulling force to the first hinge pin 92 in the first linkage assembly 9, so that the two first linkages 91 fold relative to each other, thereby causing the two first locking blocks 5 to move relative to each other and quickly disengage from the first locking frames 7. Similarly, the operator only needs to apply a pulling force to the second hinge pin 102 in the second linkage assembly 10, so that the two second linkages 101 fold relative to each other, thereby causing the two second locking blocks 6 to move relative to each other and quickly disengage from the two second locking frames 8.

[0037] Finally, to facilitate operation, so that the disengagement of each locking frame on the back plate 2 from each locking block in the middle frame 1 can be completed from only one operating point on the outside of the middle frame 1, a first rack plate 11 is connected to the first connecting rod assembly 9, and a second rack plate 12 is connected to the second connecting rod assembly 10. A carrier plate 13 is provided in the middle of the middle frame 1, and a gear 14 is provided on the carrier plate 13. The first rack plate 11 and the second rack plate 12 are symmetrically meshed on the upper and lower sides of the gear 14. One end of the first rack plate 11 meshes with the bottom side of the gear 14 through a meshing surface, and the other end of the first rack plate 11 is provided with a hook that connects to the two first connecting rods 91, which are hinged together by the first hinge shaft 92. On the outer side, a pull plate 15 is connected to the second rack plate 12. An operation hole 111 is provided at the left end of the middle frame 1, located on the linear movement path of the pull plate 15. When the pull plate 15 drives the second rack plate 12 to move to the left, it can drive the second connecting rod assembly 10 to fold. When the pull plate 15 drives the second rack plate 12 to move to the left, it can also engage the gear 14 to rotate counterclockwise. The gear 14 drives the first rack plate 11 to move to the right, while also driving the first connecting rod assembly 9 to fold. One end of the second rack plate 12 is engaged with the top and bottom sides of the gear 14 through the meshing surface. The other end of the second rack plate 12 is provided to be hung on the outer side of the two second connecting rods 101 that are hinged together by the second hinge shaft 102.

[0038] Therefore, when the operator inserts their finger into the operating hole 111 and pulls the pull plate 15 outward, the pull plate 15 will drive the second rack plate 12 to move outward. The teeth on the second rack plate 12 will mesh with the gear 14 and rotate counterclockwise. When the gear 14 rotates counterclockwise, it will mesh with the first rack plate 11 and the second rack plate 12 to move synchronously in the opposite direction. Since the second rack plate 12 and the first rack plate 11 move synchronously, they can drive the two first connecting rods 91 on the first connecting rod assembly 9 and the two second connecting rods 91 on the second connecting rod assembly 10. When the connecting rods 101 fold, the first connecting rods 91 fold, which can drive the first locking blocks 5 at their ends to move relative to each other. The two second connecting rods 101 fold synchronously with the first connecting rods 91, which can drive the second locking blocks 6 at their ends to move relative to each other. This causes the two first locking blocks 5 and the two second locking blocks 6 to separate from the first locking frame 7 and the second locking frame 8 on both sides of the inner surface of the back plate 2, so that the first locking frame 7 and the second locking frame 8 are no longer restricted by the first locking blocks 5 and the second locking blocks 6. Thus, the back plate 2 can be quickly removed from the middle frame 1.

[0039] In this embodiment, the relative movement between the two first locking blocks 5 and between the two second locking blocks 6 is accomplished by the relative folding movement of the two first connecting rods 91 and the two second connecting rods 101. The relative folding movement of the two first connecting rods 91 and the two second connecting rods 101 can better reflect the structural feature of "synchronization" than other transmission methods. This ensures that the relative movement between the two first locking blocks 5 and between the two second locking blocks 6 can also be "synchronized". This ensures that the two first locking blocks 5 and the two second locking blocks 6 can "synchronously and smoothly" disengage from the four locking frames 7 and 8 on the back plate 2 when they move relative to each other. Therefore, the linkage structure adopted in this embodiment is more reasonable. When disengaging, there will be no lag or advance at a certain locking position, ensuring that the back plate 2 can be removed smoothly in one go.

[0040] In this embodiment, since the relative motion of the linkage structure is also utilized, only a pull plate 15 needs to be set at the end of the second rack plate 12 as a "dragging structure" for their relative motion. Therefore, the operator only needs to operate the pull plate 15 through the operation hole 111 at the end of the middle frame 1 to realize the folding motion of the first linkage 91 and the second linkage 101. This allows the two first locking blocks 5 and the two second locking blocks 6 of the four locking blocks to quickly disengage from the two first locking frames 7 and the two second locking frames 8 of the four locking frames. Moreover, during operation, the operator only needs to operate from a "single" operation point on one side of the middle frame 1, which replaces the method of setting multiple separate buckles around the outer shell and operating multiple buckles separately during disassembly. This invention is easy to operate.

[0041] In this embodiment, a first connecting plate 3 is provided at the left end of the inner cavity of the middle frame 1, and a second connecting plate 4 is provided at the middle of the right inner side of the middle frame 1. Both the first connecting plate 3 and the second connecting plate 4 have slots 18. The first hinge shaft 92 is slidably engaged in the slot 18 on the first connecting plate 3, and the second hinge shaft 102 is slidably engaged in the slot 18 on the second connecting plate 4. Since the first hinge shaft 92 and the second hinge shaft 102 are respectively end connectors that form the two first connecting rods 91 and the two second connecting rods 101 to realize the folding structure, when the first connecting rods 91 and the second connecting rods 101 are folded, they are equivalent to being guided left and right in the slots 18 on the first connecting plate 3 and the second connecting plate 4. This ensures that the two first connecting rods 91 and the two second connecting rods 101 will not tilt up and down when they are folded. Secondly, it can also ensure that the first locking block 5 connected to the other end of the two first connecting rods 91 and the second locking block 6 connected to the other end of the two second connecting rods 101 move synchronously and have the same stroke, further ensuring that the first locking block 5 and the first locking frame 7, and the second locking block 6 and the second locking frame 8 disengage synchronously, ensuring that the back plate 2 can be removed from the middle frame 1 in one go.

[0042] like Figure 1As shown, in this embodiment, the first connecting plate 3 and the second connecting plate 4 are relatively short plates. Their length dimensions only need to be such that the slot 18 can satisfy the maximum stroke of the first hinge shaft 92 and the second hinge shaft 102 during relative movement, and that the first locking block 5 and the second locking block 6 can disengage from the first locking frame 7 and the second locking frame 8. Thus, an operating space 19 is formed at the opposite ends of the first connecting plate 3 and the second connecting plate 4, exposing racks and gears within the middle frame 1. This operating space 19 allows for the maintenance of the circuit boards and electrical components still installed on the front side of the middle frame 1 that serve the display screen when the back plate 2 is removed from the middle frame 1. This facilitates the exposure of these components to the environment and also facilitates the operation of maintenance tools.

[0043] like Figure 1 , Figure 4 , Figure 7 as well as Figure 8 As shown, a folding rod 20 is provided in the operating hole 111. The folding rod 20 is connected to the pull plate 15 via a damping shaft. Since the folding rod 20 is connected to the outer end of the pull plate 15, when the operator pulls the pull plate 15, he actually puts his hand into the operating hole 111 to pinch the folding rod 20. After the folding rod 20 is rotated outward from the operating hole 111, the folding rod 20 and the pull plate 15 are on the same straight line. This increases the length of the pull plate 15 and facilitates its operation. When the pull plate 15 is pulled outward by pinching the folding rod 20, the pull plate 15 drives the second rack plate 12 to move outward in a straight line. The second rack plate 12 will mesh with the gear 14 and rotate counterclockwise. The gear 14 will mesh with the first rack plate 11 to complete the relative movement in the opposite direction to the second rack plate 12. Therefore, the left and right folding structures are folded synchronously, and each locking block and each locking frame are separated synchronously. Simultaneously, through the aforementioned series of transmissions, the two auxiliary support frames 16 are ultimately rotated out from the bottom of the middle frame 1 for support. Since a limiting hole 151 is also provided on the pull plate 15, when the pull plate 15 is pulled outward, the limiting hole 151 will be exposed on the outside of the middle frame 1. At this time, inserting a bolt into the limiting hole 151 can restrict the pull plate 15 from retracting, freeing up both hands to concentrate on completing the maintenance work.

[0044] Springs 21 of the same size are provided between the first locking block 5 and the second locking block 6 and the inner wall of the middle frame 1. When the two first locking blocks 5 and the two second locking blocks 6 move relative to each other, the springs 21 will be compressed and shortened. At the same time, the springs 21 will store elastic force. When the pull plate 15 returns to the operating hole 111, the second rack plate 12 will also reset in the opposite direction. After the above series of transmissions, the two springs 21 will eventually release their elastic force again and quickly lengthen, so as to reset the two first locking blocks 5 and the two second locking blocks 6 in the opposite direction again. The two first connecting rods 91 and the two second connecting rods 101 will be restored from folding to extension again. At the same time, the back plate 2 is fastened to the middle frame 1. The first locking frame 7 and the second locking frame 8 on the inner side of the back plate 2 will be located on the movement path of the first locking blocks 5 and the second locking blocks 6 again. When the first locking blocks 5 and the second locking blocks 6 are disengaged, the first locking frame 7 and the second locking frame 8 will be locked again.

[0045] It should be noted that the first locking frame 7 and the second locking frame 8 are L-shaped curved frames. The inner surfaces of the first locking block 5 and the second locking block 6 are provided with slots that match the L-shaped curved frames. When the two first locking blocks 5 move in opposite directions to reset, they will engage the slots with the two first locking frames 7 on the same side, locking them in place. Similarly, when the two second locking blocks 6 move in opposite directions to reset, they will engage the slots with the two second locking frames 8 on the same side, so that when the back plate 2 is reinstalled, the four engaging positions are synchronized, facilitating operation. To further ensure a smooth effect when the two first locking blocks 5 and the two second locking blocks 6 move relative to or in opposite directions, the middle frame 1 is provided with tracks for the smooth sliding of the first locking blocks 5 and the second locking blocks 6.

[0046] like Figure 1 , Figure 2 As shown, an auxiliary support assembly is provided below the middle frame 1. The auxiliary support assembly includes an auxiliary support frame 16 hinged to the bottom of the middle frame 1 and a drive rod 17 slidingly fitted on the carrier plate 13. There are two auxiliary support frames 16, symmetrically located on both sides of the carrier plate 13. When the conference machine is in normal use, since the conference machine is mostly suspended on the wall or on a bracket, the auxiliary support frame 16 is stored in the movable slot 112 opened on the bottom side of the middle frame 1, which does not affect the appearance. Only when the back panel 2 needs to be removed will the auxiliary support frame 16 extend downward from the movable slot 112. When the auxiliary support frame 16 extends downward, it is used to support the operating table. The auxiliary support frame 16 has a curved structure and acts as a bottom support when extended, used to support the middle frame 1 and the display screen still installed on the front side of the middle frame 1 on the operating table. For maintenance of some components installed in special locations, it is convenient for the operator to complete the operation from different viewing angles.

[0047] When the back plate 2 is quickly removed from the back of the middle frame 1 in the manner described above, the auxiliary support frame 16 can automatically extend downward from the movable slot 112. The top end of the drive rod 17 is connected to the first rack plate 11, which can be connected to the first rack plate 11 by means of a connecting rod or crank. The top ends of the two auxiliary support frames 16 are hinged to the bottom end of the drive rod 17. When the first rack plate 11 drives the first connecting rod assembly 9 to fold and cause the two first locking blocks 5 to disengage from the first locking frame 7, it will also drive the top end of the drive rod 17 to move downward. Figure 1 A sleeve is welded onto the carrier plate 13, and the drive rod 17 slides on the sleeve to achieve the purpose of sliding on the carrier plate 13. When the drive rod 17 moves downward, it will push the two auxiliary support frames 16 downward from the movable slot 112. It can be seen that the operation of the two auxiliary support frames 16 moving downward from the middle frame 1 does not require separate manual operation. Instead, the synchronous movement can be completed when the folding action of the first connecting rod assembly 9 and the second connecting rod assembly 10, i.e., when the back plate 2 is removed from the middle frame 1, is completed. The structure is ingenious and easy to operate.

[0048] like Figure 2 As shown, the front end of the first hinge shaft 92 is provided with a first roller 921 that rolls in contact with the front surface of the first connecting plate 3, and the front end of the second hinge shaft 102 is provided with a second roller 103 that rolls in contact with the front surface of the second connecting plate 4. The arrangement of the first roller 921 and the second hinge shaft 102 makes the front ends of the first roller 921 and the second hinge shaft 102 form rolling bodies. Firstly, the front ends of the first roller 921 and the second hinge shaft 102 respectively form rolling guides that can move smoothly along the first connecting plate 3 and the second connecting plate 4. Secondly, it also limits the front ends of the first roller 921 and the second hinge shaft 102 to the first connecting plate 3 and the second connecting plate 4 respectively, ensuring the smooth folding movement of the two first connecting rods 91 and the two second connecting rods 101, and also preventing the first connecting rods 91 and the two second connecting rods 101 from falling off the first connecting plate 3 and the second connecting plate 4 during the folding movement.

[0049] To make the structure more reasonable when the two auxiliary supports 16 are used, a bridging assembly 22 is also provided. The bridging assembly 22 includes a rotating seat 221 that is transferred to the carrier plate 13 and a cam 222 disposed on the rotating seat 221. The rotating seat 221 is located between the top of the drive rod 17 and the bottom of the first rack plate 11. The rotating seat 221 has two functions: one is to limit the position of the first rack plate 11 on the bottom side, ensuring that the left and right linear movement of the first rack plate 11 is smooth, and the other is to ensure that the tooth surface of the first rack plate 11 can mesh with the gear 14. Another function of the rotating base 221 is to form a frictional contact between its outer circular surface and the rubber 223 on the bottom surface of the first rack plate 11, so that when the first rack plate 11 moves linearly left and right, the friction effect can drive the rotating base 221 to rotate synchronously. The rotating base 221 then drives the eccentric cam 222 to rotate. When the cam 222 rotates, it will squeeze the rounded corner 172 at the top of the rubber sleeve 171 and force the drive rod 17 to complete the automatic descent action. That is, when the drive rod 17 descends, the two auxiliary support frames 16 are rotated out synchronously from the bottom side of the middle frame 1 using the linkage structure 23 for support.

[0050] Therefore, the rotary seat 221 acts as an intermediate bridge for the lifting and lowering action of the drive rod 17. It not only ensures the smooth movement of the first rack plate 11, but also ensures that the top of the drive rod 17 is locked after the upper cam 222 applies pressure to the top of the drive rod 17. When the top of the drive rod 17 is locked, when the two auxiliary support frames 16 at its bottom end rotate out synchronously from the bottom side of the middle frame 1 through the connecting rod structure 23, it can also ensure that the two auxiliary support frames 16 can provide stable support for the middle frame 1, and ensure that the bottom surface is horizontal when the left and right auxiliary support frames 16 rotate out synchronously.
