Description

Technical Field

[0001] The present application relates to the technical field of display screens, and in particular to a liquid crystal display module structure. Background Art

[0002] The LCD module is a display device that assembles LCD display devices, connectors, peripheral circuits such as control and drive, PCB circuit boards, backlight sources, structural parts, etc. It has the characteristics of being light, thin, low power consumption and high definition. It is widely used in various electronic products such as mobile phones, computers, televisions, and instruments.

[0003] At present, a Chinese patent document with a publication number of CN216434604U discloses a side-lit liquid crystal display module structure, including a display, a bearing, a support rod, a rotating rod, a connecting rod, a ratchet gear, a block, a reset spring and a "U"-shaped plate. The display includes a shell and a screen. The screen is connected to the front side of the shell. The outer ring of the bearing is connected to the support rod, and the inner ring is connected to the rotating rod. The other end of the rotating rod is rotatably connected to the connecting rod. The left and right sides of the connecting rod are connected to ratchet gears, and the ratchet gears are located on the outside of the rotating rod. The front side of the connecting rod is connected to the shell. Two support blocks are symmetrically arranged on the middle part of the rear side of the shell. A "U"-shaped plate is slidably connected between the two support blocks. Blocks for clamping the ratchet gears are connected to the left and right sides of the rear of the "U"-shaped plate. Reset springs are connected between the two blocks and the two support blocks. The two reset springs are both sleeved on the "U"-shaped plate. The two blocks cooperate with the two ratchet gears. The user can adjust the angle of the user facing the screen and the up / down angle of the user looking directly at the screen by rotating the shell and the screen by hand.

[0004] With respect to the above-mentioned related technologies, the inventors believe that the following defects exist: when the user uses both hands to control the screen to rotate upward, the fingers are likely to touch the screen and leave fingerprints, and the grease and other substances on the hands will damage the screen layer, which will not only affect the appearance but also the display effect. Moreover, when rotating the screen downward, the user needs to adjust the "U"-shaped plate with one hand and rotate the screen with the other hand. At this time, the screen tends to rotate downward due to gravity, and it is not easy to control the rotation angle or the strength when rotating the screen. The screen is easily squeezed to form bright spots, dark spots or bad spots, causing irreparable damage to the screen. Utility Model Content

[0005] In order to improve the accuracy of adjusting the screen angle while not easily causing damage to the screen, thereby improving the display effect and service life of the screen, the present application provides a liquid crystal display module structure.

[0006] The present application provides a liquid crystal display module structure adopting the following technical solution:

[0007] A liquid crystal display module structure includes a display, a lifting rod rotatably connected to the back of the display, and a support seat arranged at one end of the lifting rod away from the rotating axis, a worm wheel is coaxially provided on the rotating axis of the display, a worm is rotatably connected to the lifting rod, the worm wheel and the worm are meshed with each other, an operating component for driving the worm to rotate is provided at one end of the worm away from the rotating axis of the lifting rod, and the operating component is detachably arranged on the worm.

[0008] By adopting the above technical solution, during normal use, the user assembles the lifting rod, the base and the display into one, and places them on the desktop for use. When the up / down angle of the display needs to be adjusted, the user drives the worm to rotate through the operating component, and the worm drives the worm wheel to rotate. When the worm wheel rotates forward, the worm wheel drives the display to rotate upward, and when the worm wheel rotates reversely, the worm wheel drives the display to rotate downward, thereby realizing the upward / downward rotation of the screen, which is convenient for the user's operation, thereby improving the user's accuracy in adjusting the up / down angle of the screen. At the same time, when the user adjusts the screen angle, it is not easy for the user to touch the screen with both hands, and it is not easy to damage the screen, which is beneficial to improving the display effect and service life of the screen.

[0009] Optionally, the worm is provided with a plug-in slot, and the operating component includes a rotating handle movably plugged into the plug-in slot, the rotating handle and the worm are movably coaxially arranged, the plug-in slot is polygonal, the rotating handle is plugged and matched with the plug-in slot, a card block is provided on the back of the display, a placement slot is provided on the card block, the side wall of the rotating handle is plugged and matched with the inner wall of the placement slot, and the rotating handle is also provided with a limiting member for maintaining a constant relative position between the rotating handle and the worm.

[0010] By adopting the above technical solution, when adjusting the angle of the screen up / down, the user inserts the rotating handle into the insertion slot. Since the insertion slot is polygonal, the rotating handle is plugged and adapted to the insertion slot. At this time, the user rotates the rotating handle to drive the worm to rotate, and the relative position of the rotating handle and the worm is kept constant by the limiter, so as to realize the upward / downward rotation of the screen, which is convenient for the user to operate the rotation of the worm.

[0011] After the adjustment is completed, the user unlocks the rotating handle and the worm gear through the limit piece and takes out the rotating handle in the direction away from the plug-in slot to realize the disassembly of the rotating handle and the worm gear. Then the rotating handle is placed in the placement slot of the card block so that the side wall of the rotating handle is engaged with the inner wall of the placement slot, thereby realizing the storage of the rotating handle located on the back of the display, reducing the impact on the overall visual effect of the display, and not easily causing the rotating handle to be lost, making it convenient for the user to take the rotating handle next time.

[0012] Optionally, a retraction groove is provided on the side wall of the rotating handle, and the limiting member includes a card bead slidably arranged in the retraction groove, and the card bead movably protrudes from the side wall of the rotating handle, the diameter of the retraction groove opening end is smaller than the diameter of the card bead, and the diameter of the retraction groove bottom wall is larger than the diameter of the card bead, and a card groove corresponding to the card bead is provided on the inner wall of the plug-in slot, and the card bead is engaged and adapted with the card groove. The rotating handle is provided with a sliding hole, the retraction groove is connected with the sliding hole, and a pressing column is slidably arranged in the sliding hole, and the sliding direction of the pressing column is consistent with the axial direction of the rotating handle, the pressing column protrudes from the end of the rotating handle away from the plug-in slot, and the pressing column is provided with an inclined groove, the inclined surface of the groove is tightly pressed against the card bead, and an elastic member is provided at the end of the pressing column away from the plug-in slot, and the elastic member always causes the pressing column to slide in a direction away from the plug-in slot.

[0013] By adopting the above technical solution, when adjusting the angle of the screen up / down, the user presses the pressing column, and the pressing column slides to the position corresponding to the groove and the card bead. Then the user inserts the rotating handle into the plug-in slot. At this time, the inner wall of the plug-in slot is pressed against the card bead, so that the card bead moves in the retreat slot toward the direction close to the groove. Then the user releases the pressing column, and the elastic member drives the pressing column to slide in the direction away from the plug-in slot. Since the retreat slot is connected to the sliding hole, the inclined surface of the groove presses against the card bead and drives the card bead to slide toward the direction close to the slot, so that the card bead is engaged with the slot, thereby achieving the constant relative position of the rotating handle and the worm gear, which is conducive to reducing the risk of the rotating handle and the worm gear being separated. Then the user rotates the rotating handle to achieve the upward / downward rotation of the screen.

[0014] After the adjustment is completed, the user presses the pressing column, and the pressing column slides to the position corresponding to the groove and the card bead. Then the user takes out the rotating handle in the direction away from the insertion slot. At this time, the inner wall of the insertion slot fits tightly against the card bead, so that the card bead moves in the retraction slot toward the groove, so that the card bead and the slot are in a non-engaged state, thereby unlocking the rotating handle and the worm gear, and then taking out the rotating handle to achieve quick disassembly of the rotating handle and the worm gear, which is convenient for user operation.

[0015] At the same time, since the diameter of the opening end of the retreat groove is smaller than the diameter of the card bead, and the diameter of the bottom wall of the retreat groove is larger than the diameter of the card bead, the card bead will not separate from the rotating handle while sliding in the retreat groove, making it easy to store the card bead when the rotating handle is stored, thereby facilitating the next adjustment of the display angle.

[0016] Optionally, a support column is rotatably provided on the support seat, the lifting rod is provided on the support column, a driven gear is provided at one end of the support column close to the support seat, a driving gear is rotatably provided on the support seat, the driven gear and the driving gear are meshed with each other, a knob is provided on the rotating shaft of the driving gear, and the knob protrudes from the support seat.

[0017] By adopting the above technical solution, when adjusting the left / right angle of the screen, the user turns the knob, the knob drives the active gear to rotate, the active gear drives the driven gear to rotate forward, the driven gear drives the support column to rotate forward, thereby driving the display to rotate forward around the support column, and the screen is rotated to the left. The user turns the knob in the opposite direction, the knob drives the active gear to rotate, the active gear drives the driven gear to rotate counterclockwise, the driven gear drives the support column to rotate counterclockwise, thereby driving the display to rotate counterclockwise around the support column, and the screen is rotated to the right.

[0018] When sharing or explaining, the user can adjust the screen angle to display the screen content by turning the knob. The user's fingers are unlikely to touch the screen, causing damage to the screen, and it is easy to operate.

[0019] Optionally, the knob slides along the rotating shaft of the driving gear and passes through the driving gear. A limiting groove is provided on the support seat, and the limiting groove is polygonal. One end of the knob located in the support seat is movably inserted into the limiting groove, and the side wall of the knob is plugged and adapted with the inner wall of the limiting groove. A reset member is provided at the end of the knob away from the limiting groove, and the reset member always makes the knob slide in the direction close to the limiting groove.

[0020] By adopting the above technical solution, when adjusting the left / right angle of the screen, the user pulls up the knob in the direction away from the support base, and the knob slides in the direction away from the support base. At this time, one end of the knob located in the support base is in a non-plugged state with the limiting groove, and then the user rotates the knob to make the knob rotate synchronously with the driving gear, thereby achieving left / right adjustment of the screen;

[0021] After the adjustment is completed, the user releases the knob, and the reset piece causes the knob to slide toward the support base. At this time, one end of the knob located inside the support base is plugged into the limiting groove. Since the limiting groove is polygonal in shape, the limiting groove limits the rotation of the knob, thereby maintaining a constant relative angle between the screen and the support base and reducing the inconvenience caused by accidental rotation of the screen.

[0022] Optionally, the lifting rod is slidably arranged on the support column, and a accommodating cavity is provided on the support column, and the accommodating cavity is open at one end away from the support seat, and the end of the lifting rod away from the worm gear is movably inserted into the accommodating cavity, and the lifting rod slides along the height direction of the display, and a screw rod is provided on the lifting rod, and the screw rod slides through the lifting rod, and one end of the screw rod close to the support seat is rotatably connected to the inner bottom wall of the accommodating cavity, and a nut is provided on one end of the lifting rod close to the support seat, and the screw rod is threadably adapted to the nut, and a driving member for driving the screw rod to rotate is provided on the support column.

[0023] By adopting the above technical solution, when adjusting the screen to rise, the user drives the screw rod to rotate through the driving member, and the screw rod drives the nut and the lifting rod to slide in the accommodating cavity along the height direction of the display in the direction away from the support seat, and the lifting rod drives the display to move in the direction away from the support seat. At the same time, the self-locking of the screw rod is used to keep the relative height between the lifting rod and the support seat constant, so as to increase the height of the screen;

[0024] When adjusting the screen to go down, the user drives the screw rod to reverse through the driving part, and the screw rod drives the nut and the lifting rod to slide along the height direction of the display toward the support base, and the lifting rod drives the display to slide toward the support base, and at the same time, the self-locking of the screw rod is used to keep the relative position of the lifting rod and the support base constant, so as to lower the height of the screen.

[0027] By adopting the above technical solution, when adjusting the height of the screen, the user turns the driving gear to rotate, the driving gear drives the lifting gear to rotate, and the lifting gear drives the lead screw to rotate, thereby adjusting the height of the screen. Since the lead screw is located in the accommodating cavity, it is not easy for the user to operate the lead screw. By using the protruding driving gear, the user can turn the driving gear to drive the lead screw to rotate, which is convenient for the user to rotate the lead screw to adjust the height of the screen.

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 liquid crystal display module structure. Figure 1 and Figure 2 A liquid crystal display module structure includes a support base 3 placed on a desktop, a lifting rod 2 is provided on the support base 3, a rotating groove 22 is provided on the lifting rod 2, a display 1 is rotatably connected to one end of the lifting rod 2 away from the support base 3, a worm gear 11 is coaxially connected to the rotating shaft of the display 1, the worm gear 11 is located in the rotating groove 22, the rotating shaft of the display 1 is horizontally arranged and parallel to the back of the display 1, a worm 21 is rotatably connected in the rotating groove 22, the rotating shaft of the worm 21 is perpendicular to the desktop, and the worm wheel 11 and the worm 21 are meshed with each other;

[0041] In order to facilitate the user to operate the worm 21, an operating component 4 is provided on the worm 21. Figure 2 , an end of the worm 21 away from the support seat 3 is provided with an insertion groove 221, and the operating component 4 includes a rotating handle 41 movably inserted into the insertion groove 221, the rotating handle 41 and the worm 21 are coaxially arranged, and one end of the rotating handle 41 inserted into the insertion groove 221 is plugged and adapted to the insertion groove 221. In the present application, the insertion groove 221 is in the shape of a regular quadrilateral. In other embodiments, the insertion groove 221 can also be a polygonal shape such as a triangle, a pentagon, or a hexagon, as long as the rotating handle 41 can be movably inserted into the insertion groove 221 and the rotating handle 41 and the worm 21 rotate synchronously;

[0042] In order to prevent the rotating handle 41 from being easily separated from the worm 21 when the rotating handle 41 is rotated, a limiting member 42 is provided on the rotating handle 41, and a retraction groove 411 is provided on the side wall of the rotating handle 41. The limiting member 42 includes a card bead 421 slidably arranged in the retraction groove 411, and the card bead 421 protrudes from the side wall of the rotating handle 41. The diameter of the open end of the retraction groove 411 is smaller than the diameter of the card bead 421, and the diameter of the bottom wall of the retraction groove 411 is larger than the diameter of the card bead 421, so that the card bead 421 slides in the retraction groove 411, and when the card bead 421 slides to protrude from the side wall of the rotating handle 41, it is not easy to separate from the rotating handle 41. A sliding hole 412 is provided at the axis of the rotating handle 41, and the sliding hole 412 is aligned with the retraction groove 411. The pressing column 423 is connected, and a pressing column 423 is slidably arranged in the sliding hole 412. The sliding direction of the pressing column 423 is consistent with the rotation axis of the rotating handle 41. The pressing column 423 protrudes from the end of the rotating handle 41 away from the plug-in slot 221. A groove 424 in the shape of an inclined surface is provided on the pressing column 423. The inclined surface of the groove 424 is movably pressed against the card bead 421. An elastic member 425 is provided at the end of the pressing column 423 away from the plug-in slot 221. The elastic member 425 always makes the pressing column 423 slide in the direction away from the plug-in slot 221. In the present application, the elastic member 425 is a return spring. A card slot 422 corresponding to the card bead 421 is provided on the inner wall of the plug-in slot 221, and the card bead 421 is card-engaged with the card slot 422.

[0043] When adjusting the up / down angle of the screen, the user presses the pressing column 423, and the pressing column 423 slides to the position where the groove 424 corresponds to the card bead 421. Then the user inserts the rotating handle 41 into the plug-in groove 221 along the rotating axis direction of the worm 21. At this time, the inner wall of the plug-in groove 221 is pressed against the card bead 421, so that the card bead 421 moves in the retreat groove 411 toward the direction close to the groove 424. Then the user releases the pressing column 423, and the elastic member 425 drives the pressing column 423 to slide in the direction away from the plug-in groove 221. Since the retreat groove 411 is connected to the sliding hole 412, the groove 424 The inclined surface of the card bead 421 is pressed against the card bead 421, and drives the card bead 421 to slide in the direction close to the card slot 422, so that the card bead 421 is engaged with the card slot 422, thereby achieving the constant relative position of the rotating handle 41 and the worm 21. Then the user rotates the rotating handle 41. Since the plug-in slot 221 is a regular quadrilateral, the rotating handle 41 is plugged and adapted with the plug-in slot 221. The rotating handle 41 drives the worm 21 to rotate, and the worm 21 drives the worm wheel 11 to rotate. When the worm wheel 11 rotates forward, the worm wheel 11 drives the display 1 to rotate upward. When the worm wheel 11 rotates reversely, the worm wheel 11 drives the display 1 to rotate downward, thereby realizing the upward / downward rotation of the screen.

[0044] After the adjustment is completed, the user presses the pressing column 423, at which time the pressing column 423 slides to the position corresponding to the groove 424 and the card bead 421, and then the user takes out the rotating handle 41 in the direction away from the insertion groove 221. At this time, the inner wall of the insertion groove 221 fits tightly against the card bead 421, so that the card bead 421 moves in the retraction groove 411 in the direction close to the groove 424, so that the card bead 421 and the card groove 422 are in a non-engaged state, thereby unlocking the rotating handle 41 and the worm 21, and then taking out the rotating handle 41 to achieve quick disassembly of the rotating handle 41 and the worm 21. At this time, since the diameter of the open end of the retraction groove 411 is smaller than the diameter of the card bead 421, and the diameter of the bottom wall of the retraction groove 411 is larger than the diameter of the card bead 421, the card bead 421 slides in the retraction groove 411 without being separated from the rotating handle 41, which is convenient for the storage of the card bead 421, thereby facilitating the next adjustment of the angle of the display 1.

[0045] Further, in order to facilitate the user to take and store the rotating handle 41, refer to Figure 1 A card block 12 is fixed to the back of the display 1, and a placement groove 122 is opened on the card block 12. The opening end of the placement groove 122 is located at the end of the card block 12 away from the back of the display 1. The placement groove 122 penetrates the card block 12 in the vertical direction, and the side wall of the rotating handle 41 is snap-fitted with the inner wall of the placement groove 122.

[0046] After the user has finished adjusting the screen rotation, the user places the rotating handle 41 into the placement groove 122 from the open end of the placement groove 122 of the card block 12, so that the side wall of the rotating handle 41 is engaged with the inner wall of the placement groove 122, thereby storing the rotating handle 41 and facilitating the user to use the rotating handle 41 next time.

[0047] Furthermore, in order to facilitate users to adjust the screen angle to display the screen content when sharing or explaining, refer to Figure 3 , a support column 5 is rotatably connected to the support seat 3, the rotation axis of the support column 5 is parallel to the rotation axis of the worm 21, the lifting rod 2 is arranged on the support column 5, a mounting cavity 36 is opened on the support seat 3, a driven gear 31 is coaxially fixed to one end of the support column 5 close to the support seat 3, a driving gear 32 is rotatably arranged on the support seat 3, the rotation axis of the driving gear 32 is parallel to the rotation axis of the driven gear 31, the driving gear 32 and the driven gear 31 are meshed with each other and are both located in the mounting cavity 36;

[0048] At the same time, in order to facilitate the rotation adjustment of the active gear 32 and reduce the inconvenience caused by accidental rotation of the screen, a rotation hole 37 coaxial with the rotation axis of the active gear 32 is opened on the support seat 3, and a knob 33 is provided on the active gear 32. One end of the knob 33 passes through the rotation hole 37 and protrudes from the upper surface of the support seat 3. A limiting hole 321 is opened on the rotation axis of the active gear 32. The knob 33 is slidably adapted to the inner wall of the limiting hole 321. A limiting groove 34 is opened on the inner bottom wall of the mounting cavity 36 at the rotation axis of the active gear 32. The knob 33 is located on the support seat. 3 is movably inserted into the limiting groove 34, and the knob 33 is plugged and adapted to the inner wall of the limiting groove 34. In the present application, the limiting groove 34 is in the shape of a regular 18-sided polygon, so that the adjustment angle is more precise. In other embodiments, the limiting groove 34 can also be a polygonal shape such as a triangle, a quadrilateral, a hexagon, etc., as long as the limiting groove 34 is implemented to limit the rotation of the knob 33, a reset member 35 is provided at one end of the knob 33 away from the limiting groove 34, and the reset member 35 always makes the knob 33 slide in the direction close to the limiting groove 34. In the present application, the reset member 35 is a reset spring.

[0049] When adjusting the left / right angle of the screen, the user pulls up the knob 33 in the direction away from the support base 3, and the knob 33 slides in the direction away from the support base 3. At this time, one end of the knob 33 located in the support base 3 is in a non-plugged state with the limiting groove 34. Then the user turns the knob 33 to make the knob 33 and the driving gear 32 rotate synchronously. The driving gear 32 drives the driven gear 31 to rotate forward, and the driven gear 31 drives the support column 5 to rotate forward, thereby driving the display 1 to rotate forward around the rotation axis of the support column 5 to achieve leftward rotation of the screen. The user turns the knob 33 in the opposite direction, and the knob 33 drives the driving gear 32 to rotate, and the driving gear 32 drives the driven gear 31 to rotate reversely, and the driven gear 31 drives the support column 5 to rotate reversely, thereby driving the display 1 to rotate reversely around the rotation axis of the support column 5 to achieve rightward rotation of the screen.

[0050] After the adjustment is completed, the user releases the knob 33, and the reset member 35 makes the knob 33 slide toward the support base 3. At this time, one end of the knob 33 located in the support base 3 is plugged into the limiting groove 34. Since the limiting groove 34 is a regular 18-sided shape, the limiting groove 34 limits the rotation of the knob 33, thereby achieving a constant relative position between the screen and the support base 3.

[0051] Further, in order to adjust the screen height to suit the user in different sitting postures or different working conditions, refer to Figure 3 The lifting rod 2 is slidably arranged on the support column 5, and a accommodating chamber 51 is provided on the support column 5. The end of the accommodating chamber 51 away from the support seat 3 is open. The end of the lifting rod 2 away from the worm gear 11 is movably inserted into the accommodating chamber 51, and the side wall of the lifting rod 2 is slidably adapted to the inner wall of the accommodating chamber 51. In the present application, the plug-in groove 221 is in the shape of a regular quadrilateral. In other embodiments, the plug-in groove 221 can also be a polygonal shape such as a triangle, a pentagon, or a hexagon. As long as the lifting rod 2 can slide in the accommodating chamber 51 and rotate synchronously with the support column 5, the lifting rod 2 slides along the height direction of the display 1, and a lifting groove 23 is provided on the lifting rod 2. A screw rod 52 is rotatably provided in the groove of the lifting rod 2. The screw rod 52 slides through the bottom end of the lifting rod 2 and is rotatably connected to the support seat 3. The rotating shaft of the screw rod 52 is parallel to the rotating shaft of the support column 5. A nut 53 is fixed at one end of the lifting rod 2 close to the support seat 3, and the screw rod 52 is threadably adapted to the nut 53.

[0052] The user drives the screw rod 52 to rotate through the driving member 54, and the screw rod 52 rotates to drive the nut 53 and the lifting rod 2 to rise and fall, thereby driving the display 1 to rise and fall, so as to achieve the height adjustment of the screen.

[0053] Furthermore, in order to facilitate the user to rotate the screw rod 52, a driving member 54 for driving the screw rod 52 to rotate is provided in the accommodating chamber 51. The driving member 54 includes a lifting gear 541 coaxially fixed to one end of the screw rod 52 close to the bottom wall of the accommodating chamber 51. The rotation axis of the lifting gear 541 is consistent with the rotation axis of the screw rod 52. A driving gear 542 is rotatably arranged in the cavity. The driving gear 542 protrudes from the outer peripheral wall of the support column 5. The rotation axis of the driving gear 542 is parallel to the rotation axis of the lifting gear 541, and the lifting gear 541 and the driving gear 542 are meshed with each other.

[0054] The user turns the driving gear 542 to rotate, the driving gear 542 drives the lifting gear 541 to rotate, and the lifting gear 541 drives the screw rod 52 to rotate, thereby adjusting the height of the screen.

[0055] Further, in order to facilitate the user to move the screen forward and backward, refer to Figure 4A clearance hole 38 is provided on the support seat 3, and a connecting rod 6 is rotatably arranged in the clearance hole 38. The connecting rod 6 includes a first connecting rod 61 and a second connecting rod 62 that are fixedly connected end to end. The first connecting rod 61 and the second connecting rod 62 are arranged at an angle, and the rotation axis of the connecting rod 6 is located at the connection between the first connecting rod 61 and the second connecting rod 62. The rotation axis of the connecting rod 6 is parallel to the rotation axis of the worm gear 11. One end of the connecting rod 6 is rotatably connected to a pressing plate 7, and the pressing plate 7 is slidably arranged in the clearance hole 38. A guide hole 64 is provided at one end of the connecting rod 6 and the pressing plate 7 for rotation. The guide hole 64 is a waist-shaped hole and the opening direction is consistent with the length direction of the connecting rod 6. A guide column 71 is fixed at the rotation connection between the pressing plate 7 and the connecting rod 6. The guide column 71 is located in the guide hole 64 and is slidably and rotatably connected to the inner wall of the guide hole 64. The other end of the connecting rod 6 is rotatably connected to a moving wheel 63, and the moving wheel 63 is movably fitted with the desktop, and the rotation axis of the moving wheel 63 is parallel to the rotation axis of the connecting rod 6.

[0056] At the same time, in order to achieve stable adjustment operation of the pressure plate 7 on the connecting rod 6, two groups of connecting rods 6 are provided, and the two groups of connecting rods 6 are arranged at intervals along the length direction of the display 1, and the two groups of connecting rods 6 are arranged symmetrically along the rotation axis of the worm 21. Each group of connecting rods 6 includes two connecting rods 6 arranged at intervals along the thickness direction of the display 1, and the two connecting rods 6 in each group share a rotating shaft, and the two connecting rods 6 in each group are symmetrically arranged along the common rotating axis. Two pressure plates 7 are provided, and one pressure plate 7 is rotatably connected to the top ends of the two connecting rods 6 in one group. A guide column 71 is fixed at the rotation connection between one pressure plate 7 and the two connecting rods 6 in the same group, and the multiple guide columns 71 correspond one to one to the multiple guide holes 64.

[0057] When the user moves the display 1 forward / backward, the user presses the pressure plate 7, and the pressure plate 7 and the guide column 71 both move downward. At the same time, since the guide hole 64 is a waist-shaped hole and the opening direction is consistent with the length direction of the connecting rod 6, the guide column 71 drives the connecting rod 6 to rotate, so that the moving wheel 63 moves downward and fits the desktop. At this time, the moving wheel 63 protrudes from the clearance hole 38, thereby causing the bottom wall of the support seat 3 to be out of contact with the desktop. At the same time, the user moves the support seat 3 to a suitable position, and then the user releases the pressure plate 7. The support seat 3 is downwardly contacted with the desktop by gravity, and the moving wheel 63 rotates around the rotation axis of the connecting rod 6 relative to the support seat 3. At the same time, the moving wheel 63 moves upward relative to the support seat 3. At this time, the moving wheel 63 is located in the clearance hole 38, the connecting rod 6 rotates relative to the support seat 3, and the end of the connecting rod 6 away from the moving wheel 63 moves upward relative to the support seat 3. The connecting rod 6 drives the pressure plate 7 and the guide column 71 to move upward relative to the support seat 3.

[0058] The implementation principle of a liquid crystal display module structure of the embodiment of the present application is as follows: when adjusting the up / down angle of the screen, the user presses the pressing column 423 to the corresponding position of the groove 424 and the card bead 421, and then the user inserts the rotating handle 41 into the plug-in slot 221, and then the user releases the pressing column 423, and the elastic member 425 makes the pressing column 423 slide, so that the groove 424 drives the card bead 421 to move, so that the card bead 421 is engaged with the card slot 422, and then the rotating handle 41 is rotated, and the rotating handle 41 drives the worm 21 to rotate, and the worm 21 drives the worm wheel 11 to rotate, thereby driving the display 1 to rotate, so as to adjust the up / down angle of the screen;

[0059] After the adjustment is completed, the user presses the button, then takes out the rotating handle 41, and then puts the rotating handle 41 into the placement groove 122 from the open end of the placement groove 122 of the clamping block 12, so that the side wall of the rotating handle 41 is engaged with the inner wall of the placement groove 122, thereby realizing the storage of the rotating handle 41.

[0060] When adjusting the left / right angle of the screen, the user pulls up the knob 33 and slides it upwards, and one end of the knob 33 located in the support base 3 is disengaged from the limiting groove 34. Then the user rotates the knob 33, and the knob 33 and the driving gear 32 rotate synchronously. The driving gear 32 drives the driven gear 31 to rotate, and the driven gear 31 drives the support column 5 to rotate, thereby driving the display 1 to rotate, so as to adjust the left / right angle of the screen.

[0061] After the adjustment is completed, the user releases the knob 33, and the reset member 35 moves the knob 33 downward, so that one end of the knob 33 located in the support base 3 is plugged into the limiting groove 34. The limiting groove 34 limits the rotation of the knob 33, thereby achieving a constant relative position between the screen and the support base 3.

[0062] When adjusting the screen height, the user turns the driving gear 542 to rotate, the driving gear 542 drives the lifting gear 541 to rotate, the lifting gear 541 drives the screw rod 52 to rotate, the screw rod 52 drives the nut 53 and the lifting rod 2 to move along the height direction of the display 1, and at the same time, through the self-locking of the screw rod 52, the relative position of the lifting rod 2 and the support base 3 is kept constant, thereby achieving the adjustment of the screen height.

[0063] When adjusting the display 1 to move forward and backward, the user presses the pressure plate 7, and the pressure plate 7 drives the connecting rod 6 to rotate, and at the same time drives the moving wheel 63 to move downward. At this time, the moving wheel 63 protrudes from the clearance hole 38, so that the bottom wall of the support seat 3 is out of contact with the desktop. At the same time, the user moves the support seat 3 to a suitable position, and then the user releases the pressure plate 7. The support seat 3 is downwardly contacted with the desktop by gravity. At this time, relative to the support seat 3, the moving wheel 63 moves upward, so that the moving wheel 63 is located in the clearance hole 38. At the same time, the connecting rod 6 rotates, and the connecting rod 6 drives the pressure plate 7 to slide upward, so as to realize the resetting of the pressure plate 7, and the display 1 can be adjusted to move forward and backward.

[0064] 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.
