Description

Technical Field

[0001] The present application relates to the technical field of console equipment, and in particular to a manually liftable and movable structure for a console. Background Art

[0002] The command console is a comprehensive management platform that integrates multiple functions such as information display, communication, and control operations. It facilitates managers to monitor, analyze, and process various types of information in real time, and realize effective scheduling and management of various resources.

[0003] Currently, common control consoles are generally divided into two types. One is a single integral floor-standing structure, which occupies a large area, is heavy and difficult to move and transport. Usually, it will not move after being positioned and installed. When the console needs to be moved, the technician lifts the console and then moves it until it moves to the designated position and then places it on the ground; the other console is a structure with universal wheels added to the bottom of the console. When the console needs to be moved, the technician unlocks the universal wheels and pushes the console to move until it moves to the designated position, and then fixes the universal wheels to fix the console.

[0004] With regard to the above-mentioned related technologies, when the first method is used to move the console, since the console occupies a large area and is heavy, it requires the cooperation of multiple technicians to operate, which is inconvenient for the technicians to move the console; when universal wheels are added to the bottom of the console, when the console needs to be moved, the technicians need to unlock multiple universal wheels one by one. After the move is completed, the multiple universal wheels need to be fixed one by one, which is cumbersome to operate, and when the console is moved to the corner of the wall, it is inconvenient to fix the universal wheels, which affects the stability of the console. Utility Model Content

[0005] In order to facilitate the movement of the console and improve the stability of the console, the present application provides a manually liftable and movable structure for the console.

[0006] The present application provides a manually liftable and movable structure for a control console using the following technical solution:

[0007] A manually liftable movable structure for a control console, comprising a fixed mainboard and a linkage rod arranged at the bottom of a control console body, the fixed mainboard being provided with two groups, the two groups of the fixed mainboard being arranged opposite to each other, a first caster board and a second caster board being provided for lifting on a side of the fixed mainboard away from the control console body, the first caster board and the second caster board being arranged opposite to each other along a length direction of the fixed mainboard, and a plurality of universal wheels being provided for rotation on a side of the first caster board and the second caster board away from the fixed mainboard, the universal wheels being arranged movably protruding from a bottom wall of the control console body, a lifting assembly for lifting and adjusting the first caster board and the second caster board being provided on the fixed mainboard, and a locking assembly for fixing the lifting assembly being provided on the fixed mainboard;

[0008] The lifting assembly includes a first connecting plate rotatably arranged on two opposite side walls of the fixed main board and a second connecting plate rotatably arranged on two opposite side walls of the fixed main board, the first connecting plate and the second connecting plate are each provided with two groups, and the two groups of the first connecting plates and the two groups of the second connecting plates are arranged at intervals along the length direction of the fixed main board, the end of the first connecting plate away from the fixed main board is rotatably connected to the first caster plate, and the end of the second connecting plate away from the fixed main board is rotatably connected to the second caster plate, the two ends of the linkage rod respectively correspond to and are fixedly connected to the two first connecting plates close to each other on the two groups of the fixed main boards, and the fixed main board is provided with a linkage component for synchronously adjusting the first connecting plate and the second connecting plate.

[0009] By adopting the above technical solution, when it is necessary to move the control console body, the technician first drives the first connecting plate to rotate, driving the first caster plate to descend, and at the same time the linkage member drives the second connecting plate to rotate, thereby driving the second caster plate to descend synchronously, and at the same time the first connecting plate drives the linkage rod to rotate, and drives the first connecting plate on another set of fixed main boards to rotate, thereby realizing the synchronous descent of the two sets of first caster plates and the two sets of second caster plates, and then making the multiple universal wheels move synchronously in the direction away from the fixed main board until the universal wheels protrude from the bottom wall of the control console body, so that the control console body is separated from the ground, and the lifting assembly is fixed by the provided locking assembly to achieve the constant state of separation of the control console body from the ground, and then the technician pushes the control console body to realize the movement of the control console body, which is convenient for moving the control console body;

[0010] After the console body is moved to the designated position, the technician unlocks the lifting assembly through the locking assembly, and the console body drops due to gravity. At this time, the universal wheel moves relative to the console body in the direction close to the fixed main board, so that the first caster plate and the second caster plate rise synchronously, thereby causing the first connecting plate and the second connecting plate to rotate synchronously until the universal wheel is located in the console body and the console body fits against the ground, thereby achieving the fixation of the console body and improving the stability of the console body fixation;

[0011] At the same time, the stability of the console body lifting and lowering is improved by setting two sets of fixed main boards, two sets of first caster plates, two sets of second caster plates and multiple universal wheels.

[0012] Optionally, the linkage member includes a connecting rod rotatably set on the fixed main board, two ends of the connecting rod respectively correspond to and are fixedly connected with two first connecting plates in the same group, a group of fixed main boards is provided with a handle plate rotatably set on the outer side wall, the first connecting plate corresponding to the connecting rod is fixedly connected to the handle plate, a linkage short plate is rotatably set on the outer side wall of the fixed main board, the linkage short plate is fixedly connected to one end of the second connecting plate away from the second caster plate, the linkage short plate is rotatably connected to one end of the linkage long plate away from the second connecting plate, and the end of the linkage long plate away from the linkage short plate is rotatably connected to one end of the adjacent first connecting plate close to the first caster plate.

[0013] By adopting the above technical solution, when the console body needs to be moved, the technician rotates the handle plate, driving the first connecting plate connected to the handle plate to rotate, and driving the connecting rod and another first connecting plate fixedly connected to the connecting rod to rotate, thereby driving the first caster plate to descend and driving the other group of two first connecting plates to rotate, so that the first connecting plate rotatably connected to the linkage long plate drives the linkage long plate and the linkage short plate to rotate, and then drives the second connecting plate fixedly connected to the linkage short plate to rotate, so that the second caster plate descends and drives the other second connecting plate rotatably connected to the second caster plate to rotate, thereby realizing the stable and synchronous descent of the first caster plate and the second caster plate.

[0014] At the same time, the handle plate drives the linkage rod to rotate, and drives the first connecting plate on another set of fixed main boards to rotate, so that the two sets of first caster plates and the two sets of second caster plates are synchronously lowered, thereby realizing the synchronous lowering of multiple universal wheels and protruding from the bottom wall of the console body, so that the console body is separated from the ground, making it convenient for technicians to synchronously lift and lower multiple universal wheels. At the same time, the lifting and lowering of the universal wheels are realized through manual mechanical transmission, thereby improving the reliability of the lifting assembly.

[0015] Optionally, the locking assembly includes a fixed ratchet coaxially arranged on the connecting rod, a limiting ratchet is coaxially slidably penetrated on the connecting rod, and the limiting ratchet is movably engaged with the side of the fixed ratchet close to each other, a clamping spring is provided on the side wall of the limiting ratchet away from the fixed ratchet, the clamping spring presses the limiting ratchet against the fixed ratchet, and a limiting part is provided on the fixed main board to limit the rotation of the limiting ratchet.

[0016] By adopting the above technical solution, when the control console body needs to be moved, the technician rotates the handle plate and drives the connecting rod and the fixed ratchet to rotate, and at the same time makes the first caster plate and the second caster plate drop. Due to the characteristics of the fixed ratchet and the limit ratchet, and the limit ratchet is arranged along the axial sliding, the fixed ratchet and the limit ratchet can rotate relative to each other, which is convenient for adjusting the handle plate and realizing the separation of the control console body from the ground.

[0017] Then the technician stops turning the handle plate. At this time, the pressing spring drives the limit ratchet to slide in the direction close to the fixed ratchet, so that the limit ratchet engages with the fixed ratchet. Due to the characteristics of the fixed ratchet and the limit ratchet, the fixed ratchet and the limit ratchet are not easy to rotate relative to each other. The limiting member set limits the rotation of the limit ratchet, so that the fixed ratchet and the connecting rod are not easy to rotate, thereby fixing the handle plate, fixing the position of the first connecting plate and the second connecting plate, thereby fixing the position of the first caster plate and the second caster plate, and then keeping the console body separated from the ground constant, which is convenient for the technician to push and move the console body.

[0018] Optionally, the end of the fixed mainboard away from the console body is open, and the limiting part includes a limiting block arranged on the inner side wall of the fixed mainboard, the limiting block is provided with a limiting groove, and a limiting column is provided on the side wall of the limiting ratchet away from the fixed ratchet, the cross-section of the limiting column is polygonal, and the end of the limiting column away from the limiting ratchet is located in the limiting groove and movably fits with the inner side wall of the limiting groove, and an adjusting part is provided in the fixed mainboard to separate the fixed ratchet from the limiting ratchet.

[0019] By adopting the above technical scheme, when the console body is separated from the ground, the clamping spring drives the limit ratchet to slide in the direction close to the fixed ratchet, and the limit ratchet is meshed with the fixed ratchet. At this time, the limiting column slides in the limiting groove and fits with the inner wall of the limiting groove, thereby limiting the rotation of the limit ratchet and realizing the fixation of the handle plate. After the console body is moved to the specified position, the fixed ratchet and the limit ratchet are separated by the set adjustment member, so that when the console body is dropped by gravity, it is not easy to hinder the rotation of the handle plate, which is convenient for unlocking the handle plate and making the universal wheel move in the direction close to the fixed main board and be located in the console body.

[0020] Optionally, the adjusting member includes a guide column arranged on the fixed ratchet, a guide groove for sliding the guide column is opened on the outer peripheral wall of the limiting ratchet, the guide column is tightly abutted against the inner side wall of the guide groove, the guide groove includes a first guide groove, a second guide groove, a third guide groove, a fourth guide groove and a fifth guide groove which are sequentially connected end to end, the first guide groove is arranged along the circumference direction of the limiting ratchet, the width of the first guide groove along the axis direction of the limiting ratchet is greater than the diameter of the guide column, and the guide column is moved along the limiting ratchet in the first guide groove. The amount of movement in the axial direction is greater than the amount of movement when the limiting ratchet and the fixed ratchet rotate, the second guide groove is arranged along the circumferential wall of the limiting ratchet toward the fixed ratchet, the third guide groove is arranged along the circumferential wall of the limiting ratchet toward the fixed ratchet in the opposite direction, the bottom end of the angle formed between the third guide groove and the second guide groove is located on the side of the top end of the angle close to the fixed ratchet, the fourth guide groove is arranged along the circumference direction of the limiting ratchet, and the fifth guide groove is arranged along the axial direction of the fixed ratchet.

[0021] By adopting the above technical solution, when it is necessary to move the control console body, the technician rotates the handle plate forward and drives the fixed ratchet to rotate. At this time, the fixed ratchet drives the guide column to rotate along the axis direction of the fixed ratchet. The guide column slides in the first guide groove along the circumference direction of the limiting ratchet and along the axis direction of the limiting ratchet, which is not easy to hinder the limiting ratchet from sliding in the direction away from the fixed ratchet, thereby separating the fixed ratchet from the limiting ratchet, making it convenient for the technician to rotate the handle plate to separate the control console body from the ground. When the guide column is located at the connection between the first guide groove and the second guide groove, the universal wheel protrudes from the bottom wall of the control console body.

[0022] After the console body moves to the specified position, the technician continues to rotate the handle plate to drive the guide column to slide to the second guide groove. Since the second guide groove is arranged obliquely, the guide column is pressed against the inner wall of the second guide groove at this time, and the guide column continues to move to the bottom end of the angle formed between the second guide groove and the third guide groove. At this time, the limit ratchet slides away from the fixed ratchet and separates from the fixed ratchet. The limit ratchet is not easy to hinder the rotation of the connecting rod, so that the handle plate is unlocked, thereby unlocking the lifting assembly, and the unlocking operation is convenient;

[0023] The technician then releases the handle plate, and the console body drops under gravity, causing the handle plate to reverse, driving the fixed ratchet and the connecting rod to rotate rapidly. Since the bottom end of the angle formed by the second guide slot and the third guide slot is located on the side of its top end close to the fixed ratchet, the guide post now slides to the third guide slot and is pressed against the inner side wall of the third guide slot away from the fixed ratchet, and the guide post continues to slide along the third guide slot toward the fourth guide slot, driving the limiting ratchet to continue to slide in the direction away from the fixed ratchet, until the guide post slides to the position where the fourth guide slot is connected with the fifth guide slot, and then the pressing spring drives the limiting ratchet to slide in the direction close to the fixed ratchet, so that the guide post slides to the position where the fifth guide slot is connected with the first guide slot. At this time, the fixed ratchet is meshed with the limiting ratchet, and the handle plate is in a vertical position, which is convenient for the next rotation adjustment of the handle plate to realize the fixing / unlocking of the handle plate, and when the console body needs to be moved, the fixing / unlocking operation of the handle plate is convenient and quick.

[0024] Optionally, a plurality of friction blocks are slidably provided on the bottom wall of the limiting groove, and the plurality of friction blocks are evenly spaced along the circumference direction of the connecting rod. The friction block is close to the side wall of the connecting rod and is movably pressed against the circumferential wall of the connecting rod. The end of the friction block close to the limiting column is sharp, and the inclined side of the friction block is movably pressed against the inclined side of the limiting column.

[0025] By adopting the above technical solution, when the guide column slides into the third guide groove and continues to slide along the third guide groove, the guide column drives the limit ratchet to continue to slide in the direction away from the fixed ratchet. At this time, the limiting column continues to slide in the direction close to the bottom wall of the limiting groove, so that the inclined side of the limiting column and the inclined sides of multiple friction blocks are all pressed against each other, and drive the multiple friction blocks to slide in the direction close to the axis of the connecting rod, so that the side walls of the friction blocks close to the connecting rod are pressed against the circumferential wall of the connecting rod, and the rotation speed of the connecting rod is reduced by the friction force when the two are pressed against each other, thereby reducing the rotation speed of the connecting rod and the handle plate, thereby reducing the rising speed of the first caster plate and the second caster plate relative to the console body, thereby improving the stability of the console body when it descends.

[0026] Optionally, the fixed ratchet is coaxially slidably arranged on the connecting rod, a positioning bolt is threadedly connected to the fixed ratchet, the small head end of the positioning bolt is movably pressed against the circumferential wall of the connecting rod, and the axis of the positioning bolt is perpendicular to the axis of the connecting rod.

[0027] By adopting the above technical solution, when the friction block is used for a long time and the fit between the friction block and the connecting rod is not tight, affecting the performance of the friction block, the technician unscrews the positioning bolt and slides to adjust the distance between the fixed ratchet and the limiting block, thereby adjusting the distance that the friction block slides closer to the axis of the connecting rod when the limiting column presses against the friction block, thereby adjusting the tightness between the friction block and the connecting rod, thereby adjusting the friction force between the friction block and the connecting rod and increasing the service life of the friction block.

[0028] Optionally, buffer pads are provided on the side walls of the first caster board and the second caster board close to the fixed main board.

[0029] By adopting the above technical solution, when the console body descends too quickly, the provided buffer pad will not easily cause the first caster board and the second caster board to approach the fixed main board due to inertia and collide with the fixed main board, thereby reducing the risk of damage to the fixed main board, the first caster board and the second caster board, and reducing the noise during collision.

[0030] In summary, the present application includes at least one of the following beneficial technical effects:

[0031] 1. By setting a fixed main board, a linkage rod, a first caster plate, a second caster plate, a universal wheel, and a lifting assembly for lifting and adjusting the first caster plate and the second caster plate, when the console body needs to be moved, the technician drives the lifting assembly to drive the first caster plate and the second universal wheel to synchronously descend, and realizes the synchronous descent of the two groups of first caster plates and the two groups of second caster plates through the provided linkage rod, so that the multiple universal wheels move synchronously in the direction away from the fixed main board until the universal wheel protrudes from the bottom wall of the console body, so that the console body is separated from the ground, and then the technician pushes the console body and moves the console body, so as to facilitate the movement of the console body. After the console body moves to the specified position, the technician stops driving the lifting assembly, and the console body descends due to gravity. At this time, the universal wheel rises relative to the console body until the universal wheel is located in the console body, and the console body is located on the ground, thereby realizing the fixation of the console body and improving the stability of the console body fixation;

[0032] 2. Through the provided handle plate, connecting rod, fixed ratchet, limiting ratchet, holding spring, limiting piece and guide column, a guide groove is provided on the limiting ratchet, and the guide groove includes a first guide groove, a second guide groove, a third guide groove, a fourth guide groove and a fifth guide groove which are sequentially connected end to end. The technician drives the guide column to rotate around the axis of the fixed ratchet by rotating the handle plate and makes the guide column slide in the guide groove, so that the limiting ratchet slides axially, thereby fixing / unlocking the connecting rod and the handle plate, and the fixing / unlocking operation of the handle plate is convenient and quick. When the handle plate is fixed, the holding spring drives the limiting ratchet to slide in the direction close to the fixed ratchet and makes the limiting ratchet mesh with the fixed ratchet, and limits the rotation of the limiting ratchet by the limiting piece, thereby fixing the handle plate and maintaining the constant state of separation between the console body and the ground, which is convenient for the technician to push and move the console body;

[0033] 3. Through the provided friction block, since the end of the friction block and the limiting column that is close to each other is sharp, when the guide column slides into the third guide groove and continues to slide along the third guide groove, the guide column drives the limit ratchet to continue to slide. At this time, the limiting column continues to slide in the direction close to the bottom wall of the limiting groove, so that the inclined side of the limiting column and the inclined sides of multiple friction blocks are tightly pressed against each other, and drive multiple friction blocks to slide in the direction close to the axis of the connecting rod, so that the friction block and the circumferential wall of the connecting rod are pressed against each other, and the friction force when the two are pressed against each other is used to reduce the rotation speed of the connecting rod, thereby reducing the rotation speed of the connecting rod and the handle plate, thereby reducing the rising speed of the first caster plate and the second caster plate relative to the console body, thereby improving the stability of the console body when it descends.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] The present application embodiment discloses a manually liftable movable structure for a control console. Figure 1 and Figure 2 A manually liftable movable structure for a console includes a fixed mainboard 1 installed at the bottom of a console body 6. The fixed mainboard 1 and the console body 6 are both rectangular parallelepiped, and the bottom wall of the console body 6 is movably fitted with the ground. The fixed mainboard 1 is provided with two groups, and the two groups of fixed mainboards 1 are arranged relatively along the width direction of the console body 6. The bottom side of the fixed mainboard 1 is lifted and provided with a first caster plate 11 and a second caster plate 12. The first caster plate 11 and the second caster plate 12 are arranged relatively along the length direction of the fixed mainboard 1. The bottom end of the first caster plate 11 is open, and the first caster plate 11 is perpendicular to the two opposite sides of the length direction of the fixed mainboard 1. The side wall is also open, and the shape of the second caster board 12 is consistent with the first caster board 11. The first caster board 11 and the second caster board 12 are rotatably connected to multiple universal wheels 13 on the inner bottom walls. The universal wheels 13 are movably protruded from the bottom wall of the console body 6. In the present application, there are two universal wheels 13. In other embodiments, the universal wheels 13 can also be set to three, five, six or more. The layout method is consistent with the present application. In order to reduce the collision between the fixed main board 1 and the first caster board 11, and the fixed main board 1 and the second caster board 12, a buffer pad 14 is fixed on the top wall of the first caster board 11 and the second caster board 12.

[0041] In order to adjust the lifting of the first caster plate 11 and the second caster plate 12, a lifting assembly 2 is provided on the fixed main board 1. Figure 1 and Figure 2The lifting assembly 2 includes a first connecting plate 21 rotatably connected to the fixed main board 1 on the opposite side walls perpendicular to the length direction of the fixed main board 1, and a second connecting plate 22 rotatably connected to the fixed main board 1 on the opposite side walls perpendicular to the length direction of the fixed main board 1. The lifting assembly 2 includes a first connecting plate 21 and a second connecting plate 22. The first connecting plate 21 and the second connecting plate 22 are each provided with two groups. Each group of first connecting plates 21 includes two first connecting plates 21 rotatably connected to the opposite side walls of the first caster plate 11. Each group of second connecting plates 22 includes two second connecting plates 22 rotatably connected to the opposite side walls of the first caster plate 11. The two groups of first connecting plates 21 and the two groups of second connecting plates 22 are fixed along The main board 1 is arranged at intervals in the length direction, and the end of the first connecting plate 21 away from the first caster plate 11 is rotatably connected to the side wall of the fixed main board 1, and the end of the second connecting plate 22 away from the second caster plate 12 is rotatably connected to the side wall of the fixed main board 1. A linkage rod 4 is fixedly connected between two relatively close first connecting plates 21 on the two groups of fixed main boards 1, and the linkage rod 4 is located between two relatively first connecting plates 21 away from the second caster plate 12. The rotation axes of the first connecting plate 21 and the second connecting plate 22 are consistent with the length direction of the fixed main board 1. In order to improve the stability of the first caster plate 11 and the second caster plate 12 when lifting and lowering, the first connecting plate 21 and the second connecting plate 22 on the same side are arranged at an angle.

[0042] In order to synchronously adjust the first connecting plate 21 and the second connecting plate 22 to achieve the synchronous lifting of the first caster plate 11 and the second caster plate 12, a linkage member 23 is provided on the fixed main board 1. Figure 2 The linkage member 23 includes a connecting rod 231 rotatably connected to the fixed main board 1, the connecting rod 231 is coaxial with the linkage rod 4 and fixedly connected to the two first connecting plates 21 of the same group, a handle plate 232 is rotatably connected to the outer wall of a group of fixed main boards 1, and the end of the first connecting plate 21 corresponding to the connecting rod 231 away from the first caster plate 11 is fixedly connected to the handle plate 232, and the rotating axis of the handle plate 232 is consistent with the rotating axis of the connecting rod 231. When the console body 6 is fixed, the height direction of the handle plate 232 is consistent with that of the fixed main board 1.

[0043] At the same time, a linkage short plate 233 is rotatably connected to the outer side wall of the fixed main board 1, and the linkage short plate 233 is fixedly connected to the end of the second connecting plate 22 away from the second caster plate 12 and is angled. The linkage short plate 233 is located between the first caster plate 11 and the second caster plate 12, making the structure more compact, and a linkage long plate 234 is rotatably connected to the end of the linkage short plate 233 away from the second connecting plate 22, and the end of the linkage long plate 234 away from the linkage short plate 233 is rotatably connected to the adjacent first connecting plate 21, and the rotation axis of the linkage long plate 234 is parallel to the rotation axis of the first connecting plate 21, and the rotation axis of the linkage long plate 234 away from the second connecting plate 22 is consistent with the rotation axis of the first connecting plate 21 away from the fixed main board 1.

[0044] When the console body 6 needs to be moved, the technician rotates the handle plate 232 in the forward direction, driving the first connecting plate 21 fixedly connected to the handle plate 232 to rotate, and driving the connecting rod 231 and the other first connecting plate 21 fixedly connected to the connecting rod 231 to rotate, so that the first caster plate 11 descends and the other group of two first connecting plates 21 rotates, so that the first connecting plate 21 rotatably connected to the linkage long plate 234 drives the linkage long plate 234 and the linkage short plate 233 to rotate, and then drives the second connecting plate 22 fixedly connected to the linkage short plate 233 to rotate, so that the second caster plate 12 descends and drives the other second connecting plate 22 to rotate, so as to realize the stable and synchronous descent of the first caster plate 11 and the second caster plate 12.

[0045] At the same time, the handle plate 232 drives the linkage rod 4 to rotate, and drives the first connecting plate 21 on the other set of fixed main boards 1 to rotate, so that the two sets of first caster plates 11 and the two sets of second caster plates 12 are synchronously lowered, thereby realizing that the eight universal wheels 13 on the two sets of first caster plates 11 and the two sets of second caster plates 12 are synchronously lowered and protrude from the bottom wall of the console body 6, so that the console body 6 is separated from the ground, which is convenient for technicians to synchronously lift and lower multiple universal wheels 13, and then the technicians push the console body 6 to move, which is convenient for moving the console body 6, and at the same time, the lifting and lowering of the universal wheels 13 are realized through manual mechanical transmission, thereby improving the reliability of the lifting assembly 2.

[0046] After the console body 6 moves to the specified position, the technician releases the handle plate 232, and the console body 6 drops due to gravity. At this time, the universal wheel 13 rises relative to the console body 6, driving the first caster plate 11 and the second caster plate 12 to rise synchronously, thereby driving the first connecting plate 21 and the second connecting plate 22 to rotate synchronously. When the console body 6 descends too fast, the provided buffer pad 14 is not likely to cause the first caster plate 11 and the second caster plate 12 to approach the fixed main board 1 due to inertia and collide with the fixed main board 1, thereby reducing the risk of damage to the fixed main board 1, the first caster plate 11 and the second caster plate 12, and reducing the noise during collision, until the universal wheel 13 is located in the console body 6 and the console body 6 is in contact with the ground, the console body 6 is fixed, and the stability of the console body 6 is improved. At this time, the handle plate 232 rotates in the opposite direction to be consistent with the height direction of the fixed main board 1.

[0047] Furthermore, in order to fix the position of the universal wheel 13 when the console body 6 is moved so as to facilitate the movement of the console body 6, a locking assembly 3 is provided on the fixed main board 1. Figure 2 and Figure 3 The bottom end of the fixed main board 1 is open, and the locking assembly 3 includes a fixed ratchet 31 coaxially arranged on the connecting rod 231. The connecting rod 231 coaxially slides through and connects to a limiting ratchet 32. The limiting ratchet 32 ​​and the fixed ratchet 31 are movably engaged with each other on one side, and the limiting ratchet 32 ​​and the fixed ratchet 31 are both located in the fixed main board 1. A tightening spring 33 is fixed on the side wall of the limiting ratchet 32 ​​away from the fixed ratchet 31, and the tightening spring 33 causes the limiting ratchet 32 ​​to press against the fixed ratchet 31.

[0048] In order to limit the rotation of the fixed ratchet 31 and the limiting ratchet 32 ​​and facilitate the fixing of the handle plate 232, a limiting member 34 for limiting the rotation of the limiting ratchet 32 ​​is provided on the fixed main board 1. Figure 2 and Figure 3 The limiting member 34 includes a limiting block 341 fixed on the inner side wall of the fixed main board 1, and a limiting groove 342 is opened on the limiting block 341. A limiting column 343 is fixed on the side wall of the limiting ratchet 32 ​​away from the fixed ratchet 31, and the connecting rod 231 slides through the limiting column 343. The cross-section of the limiting column 343 is variable in shape. One end of the limiting column 343 away from the limiting ratchet 32 ​​is located in the limiting groove 342 and movably fits with the inner side wall of the limiting groove 342. In the present application, the cross-section of the limiting column 343 is a regular quadrilateral. In other embodiments, the cross-section of the limiting column 343 can also be a polygonal shape such as a triangle, a pentagon, or a hexagon, as long as the limiting column 343 can slide in the limiting groove 342 without rotating.

[0049] When the console body 6 needs to be moved, the technician continues to rotate the handle plate 232 in the forward direction, driving the connecting rod 231 and the fixed ratchet 31 to rotate, and at the same time lowering the universal wheel 13. Due to the characteristics of the fixed ratchet 31 and the limiting ratchet 32, and the axial sliding arrangement of the limiting ratchet 32, the fixed ratchet 31 and the limiting ratchet 32 ​​can rotate relative to each other at this time, which facilitates the forward rotation of the handle plate 232 until the universal wheel 13 protrudes from the bottom wall of the console body 6, thereby separating the console body 6 from the ground.

[0050] Then the technician stops turning the handle plate 232, and the pressing spring 33 drives the limiting ratchet 32 ​​to slide in the direction close to the fixed ratchet 31, and at the same time the limiting column 343 slides in the limiting groove 342 in the direction away from the fixed ratchet 31 until the limiting ratchet 32 ​​is pressed against the fixed ratchet 31. At this time, the limiting ratchet 32 ​​is meshed with the fixed ratchet 31, and the limiting column 343 is located in the limiting groove 342 and fits with the inner wall of the limiting groove 342. Due to the characteristics of the fixed ratchet 31 and the limiting ratchet 32, the fixed ratchet 31 and the limiting ratchet 32 ​​are not easy to rotate relative to each other, and the cross-section of the limiting column 343 is a regular quadrilateral, thereby limiting the rotation of the fixed ratchet 31 and the limiting ratchet 32, thereby fixing the handle plate 232, thereby maintaining the constant state of separation between the console body 6 and the ground, making it convenient for the technician to push and move the console body 6.

[0051] Furthermore, in order to separate the fixed ratchet 31 from the limiting ratchet 32 ​​and facilitate unlocking the handle plate 232, an adjusting member 35 is provided on the fixed main board 1. Figure 4The adjusting member 35 includes a support block 358 fixed on the circumferential wall of the fixed ratchet 31, a guide column 351 is fixed on the support block 358, a guide groove 352 for the guide column 351 to slide is provided on the outer circumferential wall of the limiting ratchet 32, the guide column 351 is tightly abutted against the inner side wall of the guide groove 352, the guide column 351 is cylindrical, and the guide axis is arranged perpendicular to the axis direction of the fixed ratchet 31, the guide groove 352 includes a first guide groove 353, a second guide groove 354, a third guide groove 355, a fourth guide groove 356 and a fifth guide groove 357 connected end to end in sequence, the first guide groove 353 is arranged along the circumference direction of the limiting ratchet 32, and the first guide groove 353 is arranged along the axis direction of the limiting ratchet 32 The width is greater than the diameter of the guide column 351, and the amount of movement of the guide column 351 in the first guide groove 353 along the axial direction of the limiting ratchet 32 ​​is greater than the amount of movement when the limiting ratchet 32 ​​and the fixed ratchet 31 rotate. The second guide groove 354 is arranged obliquely along the circumferential wall of the limiting ratchet 32 ​​toward the fixed ratchet 31, and the third guide groove 355 is arranged obliquely in the opposite direction along the circumferential wall of the limiting ratchet 32 ​​toward the fixed ratchet 31. The bottom end of the angle formed between the third guide groove 355 and the second guide groove 354 is located on the side of the top end of the angle close to the fixed ratchet 31. The fourth guide groove 356 is arranged along the circumference direction of the limiting ratchet 32, and the fifth guide groove 357 is arranged along the axial direction of the fixed ratchet 31.

[0052] When it is necessary to move the console body 6, the technician rotates the handle plate 232 and drives the fixed ratchet 31 to rotate forward, so that the fixed ratchet 31 drives the support block 358 and the guide column 351 to rotate along the axial direction of the fixed ratchet 31. At this time, the guide column 351 slides in the first guide groove 353 along the circumference direction of the limiting ratchet 32. At the same time, the fixed ratchet 31 drives the limiting ratchet 32 ​​to slide in the direction away from the fixed ratchet 31, so that the guide column 351 slides in the first guide groove 353 along the axial direction of the limiting ratchet 32. Since the width of the first guide groove 353 along the axial direction of the limiting ratchet 32 ​​is greater than the diameter of the guide column 351, and the amount of movement of the guide column 351 in the first guide groove 353 along the axial direction of the limiting ratchet 32 ​​is greater than the amount of movement when the limiting ratchet 32 ​​and the fixed ratchet 31 rotate, it is not easy to hinder the sliding of the limiting ratchet 32, thereby separating the fixed ratchet 31 from the limiting ratchet 32, making it convenient for the technician to rotate the handle plate 232.

[0053] After the console body 6 moves to the specified position, the technician continues to rotate the handle plate 232 to drive the guide column 351 to slide to the second guide groove 354. Since the second guide groove 354 is arranged obliquely, the guide column 351 is pressed against the inner wall of the second guide groove 354 at this time, and the guide column 351 continues to move to the bottom end of the angle formed between the second guide groove 354 and the third guide groove 355. At this time, the limit ratchet 32 ​​slides in the direction away from the fixed ratchet 31 and separates from the fixed ratchet 31. The limit ratchet 32 ​​is not easy to hinder the rotation of the connecting rod 231, so that the handle plate 232 is unlocked, thereby realizing the unlocking of the lifting assembly 2, and the unlocking operation is convenient;

[0054] The technician then loosens the handle plate 232, and the console body 6 drops due to gravity, causing the handle plate 232 to reverse, driving the fixed ratchet 31 and the connecting rod 231 to rotate rapidly. Since the bottom end of the angle formed by the second guide groove 354 and the third guide groove 355 is located on the side of its top end close to the fixed ratchet 31, at this time, the guide column 351 slides into the third guide groove 355 and abuts against the inner side wall of the third guide groove 355 away from the fixed ratchet 31, and the guide column 351 continues to slide along the third guide groove 355 toward the fourth guide groove 356, driving the limiting ratchet 32 ​​to continue to slide in the direction away from the fixed ratchet 31. The guide post 351 moves until it slides to the position where the fourth guide groove 356 and the fifth guide groove 357 are connected, and then the spring 33 is pressed to drive the limiting ratchet 32 ​​to slide in the direction close to the fixed ratchet 31, so that the guide post 351 slides to the position where the fifth guide groove 357 is connected to the first guide groove 353. At this time, the fixed ratchet 31 is meshed with the limiting ratchet 32, and the handle plate 232 is in a vertical position, which is convenient for the next rotation adjustment of the handle plate 232 to achieve the fixing / unlocking of the handle plate 232, and when the console body 6 needs to be moved, the fixing / unlocking operation of the handle plate 232 is convenient and quick.

[0055] Further, in order to reduce the speed of the console body 6 when it is lowered by gravity and improve the stability of the console body 6 when it is lowered, refer to Figure 3 , a plurality of friction blocks 5 are slidably connected to the bottom wall of the limiting groove 342, and the plurality of friction blocks 5 are evenly spaced along the circumference direction of the connecting rod 231, and the plurality of friction blocks 5 all slide in the direction close to the axis of the connecting rod 231, and the side wall of the friction block 5 close to the connecting rod 231 is movably pressed against the circumferential wall of the connecting rod 231, and the end of the friction block 5 close to the limiting column 343 is sharp, and the inclined side of the friction block 5 is movably pressed against the inclined side of the limiting column 343. In the present application, four friction blocks 5 are set, and in other embodiments, the friction blocks 5 can also be set to three, five, six or other multiple ones, and the arrangement method is consistent with the present application.

[0056] When the guide column 351 continues to slide along the third guide groove 355, the guide column 351 drives the limiting ratchet 32 ​​to continue to slide in the direction away from the fixed ratchet 31. At this time, the limiting column 343 continues to slide in the direction close to the bottom wall of the limiting groove 342, so that the inclined side of the limiting column 343 is tightly pressed against the inclined sides of the four friction blocks 5, and drives the four friction blocks 5 to slide in the direction close to the axis of the connecting rod 231, so that the side walls of the friction blocks 5 close to the connecting rod 231 are tightly pressed against the circumferential wall of the connecting rod 231. The friction force when the two are pressed against each other reduces the rotation speed of the connecting rod 231, thereby reducing the rotation speed of the connecting rod 231 and the handle plate 232, thereby reducing the rising speed of the first caster plate 11 and the second caster plate 12 relative to the console body 6, thereby improving the stability of the console body 6 when it descends.

[0057] Further, in order to adjust the friction between the friction block 5 and the connecting rod 231 and increase the service life of the friction block 5, refer to Figure 2 The fixed ratchet 31 is coaxially slidably connected to the connecting rod 231, and a positioning bolt 311 is threadedly connected to the fixed ratchet 31. The small head end of the positioning bolt 311 is movably pressed against the circumferential wall of the connecting rod 231, and the axis of the positioning screw is perpendicular to the axis of the connecting rod 231.

[0058] When the performance of the friction block 5 is affected by the loose fit between the friction block 5 and the connecting rod 231 due to long-term use, the technician unscrews the positioning bolt 311 and slides to adjust the distance between the fixed ratchet 31 and the limiting block 341, thereby adjusting the distance that the friction block 5 slides toward the axis of the connecting rod 231 when the limiting column 343 presses against the friction block 5, thereby adjusting the tightness between the friction block 5 and the connecting rod 231, and then the technician tightens the positioning bolt 311 and fixes the fixed ratchet 31 to adjust the friction force between the friction block 5 and the connecting rod 231, thereby increasing the service life of the friction block 5.

[0059] The implementation principle of the manual lifting and moving structure for the control console of the embodiment of the present application is as follows: when the control console body 6 needs to be moved, the technician rotates the handle plate 232 in the positive direction, and the handle plate 232 drives the first connecting plate 21 to rotate, so that the first caster plate 11 descends and drives the remaining first connecting plates 21 rotatably connected to the first caster plate 11 to rotate synchronously, drives the linkage long plate 234 and the linkage short plate 233 to rotate, thereby driving the second connecting plate 22 to rotate, so that the second caster plate 12 descends and drives the remaining second connecting plates 22 rotatably connected to the second caster plate 12 The first connecting plate 21 rotates synchronously, and at the same time, the first connecting plate 21 drives the linkage rod 4 and a group of first connecting plates 21 on the fixed main board 1 to rotate, so that the two groups of first caster plates 11 and the two groups of second caster plates 12 descend synchronously, so that the universal wheel 13 descends and protrudes from the bottom wall of the console body 6, so that the console body 6 is separated from the ground, and at the same time, the fixed ratchet 31 is engaged with the limiting ratchet 32 ​​to fix the handle plate 232. The technician can then loosen the handle plate 232, thereby keeping the console body 6 separated from the ground, and then the technician pushes the console body 6 to move.

[0060] After the console body 6 moves to the specified position, the technician continues to rotate the handle plate 232 in the forward direction, driving the fixed ratchet 31 to rotate, driving the limit ratchet 32 ​​to slide and separate from the fixed ratchet 31, and then the technician releases the handle plate 232. The console body 6 is lowered by gravity and drives the universal wheel 13, the first caster plate 11 and the second caster plate 12 to rise, thereby rotating the first connecting plate 21 and the second connecting plate 22 and driving the handle plate 232 to reverse. At this time, the guide column 351 slides in the guide groove 352, causing the limit ratchet 32 ​​to slide and separate from the fixed ratchet 31. The ratchet 32 ​​remains in a separated state from the fixed ratchet 31, and drives the limiting ratchet 32 ​​to continue sliding, so that the inclined side of the limiting column 343 is pressed against the inclined side of the friction block 5, thereby pressing the friction block 5 against the connecting rod 231. The friction between the friction block 5 and the connecting rod 231 reduces the rotation speed of the connecting rod 231, so that the console body 6 is steadily lowered until the console body 6 is in contact with the ground. At this time, the handle plate 232 is rotated to a vertical position, and the universal wheel 13 is located in the console body 6 to fix the console body 6.

[0061] When the friction force between the friction block 5 and the connecting rod 231 needs to be adjusted, the technician unscrews the positioning bolt 311 and slides to adjust the distance between the fixed ratchet 31 and the limiting block 341, thereby adjusting the distance that the friction block 5 slides toward the axis of the connecting rod 231 when the limiting column 343 presses against the friction block 5, thereby adjusting the tightness between the friction block 5 and the connecting rod 231, and then the technician tightens the positioning bolt 311 to fix the fixed ratchet 31.

[0062] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
