[0047] Among them, threaded holes are formed at the positions corresponding to the rotating shafts at the lower end of the main display screen. Bolts are screwed inside the threaded holes. Handles for easy screwing are welded to the bolts. The distance between the two corresponding rotating shafts is greater than the sum of the thicknesses of the main display screen and the secondary display screen.

[0048] Beneficial effects:

[0049] 1. The support column of the present invention is hollow inside and has a chute on the outside. Both ends of the lifting drive screw are rotationally connected to the upper and lower ends of the support column through bearings. The lifting bevel gear is fixedly sleeved at the lower part of the lifting drive screw and can mesh with the double-sided drive bevel gear. The lifting box body is threadedly connected to the lifting drive screw through a lifting threaded hole, and the front end is rotationally connected to the back of the main display screen through a support U-shaped frame. When the bracelet is pushed inward to drive the rod, the inner side of the double-sided drive bevel gear meshes with the lifting bevel gear. Rotating the bracelet drives the double-sided drive bevel gear to rotate, and then makes the lifting bevel gear and the lifting drive screw rotate, realizing the up and down lifting of the lifting box body to drive the main and secondary display screens, and achieving height adjustment.

[0050] 2. The angle adjustment bevel gear of the present invention is connected to the driving runner through an angle adjustment drive belt. The support runner, the angle adjustment transmission runner and the driving runner are meshed. The angle adjustment transmission runner is connected to the angle adjustment transmission bevel gear I through a transmission shaft. The angle adjustment transmission bevel gear II meshes with the angle adjustment transmission bevel gear I. The outer side of the angle adjustment transmission bevel gear II is connected to the angle adjustment gear through a transmission shaft. The angle adjustment gear meshes with the rack inside the angle adjustment bracket. The angle adjustment bracket is rotationally connected to the back of the main display screen through a support U-shaped frame. When the bracelet is pulled outward to drive the rod, the outer side of the double-sided drive bevel gear meshes with the angle adjustment bevel gear. Rotating the bracelet drives a series of transmissions, making the angle adjustment gear rotate to drive the rack to move, and realizing the angle adjustment of the main display screen.

[0051] 3. The support base of the present invention has a rotating groove with a T-shaped cross-section inside. The rotating disk is arranged therein. By rotating the rotating disk, the rotation adjustment of the entire integrated display device can be realized. After adjustment, screwing the nut on the outer side of the upper end of the support base can abut and squeeze the rotating disk to achieve rotation locking.

[0052] 4. In the drive chamber at the rear side of the lower end of the support column of the present invention, a retaining ring is fixed on the drive rod, and stable springs are sleeved on both sides. The locking drive ring is slidably installed on the drive rod and has a locking insertion rod at the upper end. There is a locking insertion hole on the back of the angle adjustment bevel gear. When the bracelet is released, the drive rod is reset under the action of the stable spring, and the locking drive ring drives the locking insertion rod to insert into the locking insertion hole, preventing the angle adjustment bevel gear from accidentally rotating and maintaining the state of the main and secondary display screens after angle adjustment.

[0053] 5. The other end of the lifting box body of the present invention is connected to a stable runner through a transmission shaft. The stable runner is sleeved with a stable bracket on the outside. The stable bracket is rotationally connected to the back of the main display screen through a support U-shaped frame. There are multiple stable holes on the upper and lower sides of the stable bracket corresponding to the stable runner. The stable spring in the cylindrical chamber on the outside of the stable runner is connected to a stable ball head, and the stable ball head can be stuck into the stable hole, increasing the damping force, avoiding the accidental downward fall of the main and secondary display screens due to gravity, and at the same time increasing the angle adjustment damping feeling to prevent excessive angle adjustment.

[0054] 6. One end of the driving rod in the driving mechanism of the present invention is fixed to the bracelet, passes through the support column, and the other end is fixed to the double-sided driving bevel gear. The driving rod can be conveniently pulled outwards or pushed inwards through the bracelet, realizing the meshing switch between the double-sided driving bevel gear and the lifting bevel gear or the angle adjustment bevel gear, and further driving the lifting or angle adjustment mechanism.

[0055] 7. The outer side of the support base of the present invention is provided with multi-stage telescopic support legs. There is a disc at the outermost side and the bottom surface is flush with the bottom surface of the support base. The support legs can be stretched according to the actual situation to increase the contact area between the support base and the bottom surface, making the device placed more stably. There are multiple spherical grooves at the bottom of the rotating disc and spherical balls are embedded, reducing the friction with the support base and making the rotation adjustment of the entire integrated display device smoother.

[0056] 8. There are grooves at the corresponding positions of the main display screen and the secondary display screen of the present invention. The rotating block is located in the groove. The four rotating shafts on the upper and lower sides are respectively inserted into the shaft holes of the main and secondary display screens to achieve rotational connection. There are threaded holes at the corresponding positions of the rotating shafts at the lower end of the main display screen. The bolt with a handle can be screwed to fix it. When not in use, the secondary display screen can be rotated towards the main display screen to cover it, protecting the display screen from collision damage.

[0057] 9. The rear side of the support slider of the present invention is fixed with a pressing belt block. The pressing belt block is elastically connected to the pressing slider on the relative inner side, so that the inner wall of the pressing slider closely adheres to the angle adjustment driving toothed belt, making the angle adjustment driving toothed belt tightly mesh with the angle adjustment transmission rotating wheel, thereby preventing the angle adjustment driving toothed belt from separating from the angle adjustment transmission rotating wheel and causing the situation that the adjustment transmission is not in place.

[0072] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present invention.

[0073] In order to achieve the above-mentioned invention object, as Figures 1-11 shown, the present invention provides a multi-screen integrated display device, including a support base 7 and a support column 4 for supporting the multi-screen integrated display device. The support column 4 is rotatably installed at the upper end position of the support base 7. It also includes a lifting and angle adjustment mechanism for the lifting and angle adjustment of the multi-screen integrated display device. The lifting and angle adjustment mechanism is installed on the support column 4. The main display screen 2 is installed at the outer side position of the lifting and angle adjustment mechanism. And both sides of the main display screen 2 are rotatably connected with secondary display screens 1. Through the lifting and angle adjustment mechanism, the height and angle adjustment of the main display screen 2 and the secondary display screens 1 can be realized. The driving mechanism is installed at the lower and inner side position of the support column 4. The driving mechanism drives the lifting and angle adjustment mechanism to lift and adjust the angle, and further realizes the adjustment of the main display screen 2 and the secondary display screens 1 connected to the lifting and angle adjustment mechanism.

[0074] Preferably, the inside of the support column 4 is a hollow chamber, and a plurality of sliding grooves 37 are opened on the outer circumference. The hollow chamber can accommodate the installation of the lifting and angle adjustment mechanism and the driving mechanism. The sliding grooves 37 can enable the components of the lifting and angle adjustment mechanism to slide up and down.

[0075] As Figure 4 , 6 , 7 shown, the driving mechanism includes a double-sided driving bevel gear 18 and a driving rod 21. The driving rod 21 is fixedly installed at one side position of the double-sided driving bevel gear 18. The other end of the driving rod 21 penetrates through the support column 4 and is exposed outside the support column 4. A hand ring 10 is fixedly installed at the outer side position of the driving rod 21. Thus, by pulling or pushing the driving rod 21 outward through the hand ring 10, the movement of the double-sided driving bevel gear 18 can be driven. Then, by rotating the hand ring 10, the double-sided driving bevel gear 18 can be driven to rotate through the driving rod 21, thereby realizing the rotation of the double-sided driving bevel gear 18.

[0076] The lifting and angle adjustment mechanism includes a lifting mechanism. The lifting mechanism includes a lifting driving screw 34. The two ends of the lifting driving screw 34 are rotatably connected to the upper and lower ends of the support column 4 through bearings. A lifting bevel gear 17 is fixedly sleeved at the lower and partial position of the lifting driving screw 34. And the lifting bevel gear 17 can be meshed and driven with the double-sided driving bevel gear 18. A lifting box body 40 is sleeved on the lifting driving screw 34. And a lifting threaded hole is opened at the central position of the lifting box body 40. The lifting box body 40 is threadedly connected with the lifting driving screw 34 through the lifting threaded hole. The front end of the lifting box body 40 is rotatably connected to the back surface of the main display screen 2 through a support U-shaped frame 6;

[0077] In this embodiment, when the driving rod 21 is pushed inward by the bracelet, the inner side of the double-sided driving bevel gear 18 on the driving rod 21 will engage with the lifting bevel gear 17. Thus, by rotating the driving rod 21 with the bracelet 10, the lifting bevel gear 17 can be driven to rotate through the double-sided driving bevel gear 18. Then, the rotating lifting bevel gear 17 can drive the lifting driving screw rod 34 to rotate. At this time, the rotating lifting driving screw rod 34 can drive the lifting box body 40 to move up and down inside the support column 4, thereby driving the main display screen 2 and the secondary display screen 1 to move up and down, so as to realize the lifting adjustment of the main display screen 2 and the secondary display screen 1.

[0078] As Figure 4 , 6 , 7, 8, 11 show that the lifting angle adjustment mechanism includes an angle adjustment mechanism. The angle adjustment mechanism includes an angle adjustment bevel gear 19 and a driving runner 44. The driving runner 44 is fixedly connected to the angle adjustment bevel gear 19 through a transmission shaft. The driving runner 44 and the angle adjustment bevel gear 19 can rotate on the support column 4 through the transmission shaft. The support runner 45 is rotatably installed at the upper rear position of the back of the support column 4. The support slider 22 is fixedly arranged at the back position of the lifting box body 40. The angle adjustment transmission runner 23 is rotatably installed at the back position of the support slider 22. An angle adjustment driving toothed belt 25 is meshed and sleeved on the driving runner 44, the support runner 45, and the angle adjustment transmission runner 23. A U-shaped cavity is opened at the rear side position inside the lifting box body 40. An angle adjustment transmission bevel gear I 42 is rotatably arranged at the rear side position inside the U-shaped cavity. The angle adjustment transmission bevel gear I 42 is connected to the angle adjustment transmission runner 23 through a transmission shaft. The angle adjustment transmission runner 23 and the angle adjustment transmission bevel gear I 42 rotate on the lifting box body 40 and the support slider 22 through the transmission shaft. An angle adjustment transmission bevel gear II 41 is installed inside the U-shaped cavity. The angle adjustment transmission bevel gear II 41 and the angle adjustment transmission bevel gear I 42 are meshed and driven. The outer side of the angle adjustment transmission bevel gear II 41 is connected with an angle adjustment gear 11 through a transmission shaft. The angle adjustment gear 11 and the angle adjustment transmission bevel gear II 41 rotate on the lifting box body 40 through the transmission shaft. The angle adjustment bracket 12 is sleeved on the outer side of the angle adjustment gear 11. A rack 15 is fixedly arranged at the lower rear position inside the angle adjustment bracket 12. The upper rear position inside the angle adjustment bracket 12 is a smooth structure. The bottom of the angle adjustment gear 11 meshes with the rack 15. The top of the angle adjustment gear 11 slides on the inner top wall of the angle adjustment bracket 12. One end of the angle adjustment bracket 12 away from the support column 4 is rotatably connected to the back of the main display screen 2 through a support U-shaped frame 6;

[0079] In this embodiment, by pulling the drive rod 21 outward through the bracelet 10, the outer side of the double-sided drive bevel gear 18 is engaged with the angle adjustment bevel gear 19. At this time, when the bracelet 10 is rotated, the rotating bracelet 10 drives the angle adjustment bevel gear 19 to rotate through the double-sided drive bevel gear 18 on the drive rod 21. Then, the rotating adjustment bevel gear drives the drive runner 44 to rotate through the transmission shaft. At this time, the rotating drive runner 44 can drive the angle adjustment drive belt 25 to transmit power. The angle adjustment drive belt 25 in transmission engages and drives the angle adjustment transmission runner 23 to rotate, so that both sides of the angle adjustment drive belt 25 can drive the angle adjustment transmission runner 23. At this time, the rotating angle adjustment transmission runner 23 can drive the adjustment transmission bevel gear I 43 to rotate through the transmission shaft. Then, the rotating angle adjustment transmission bevel gear I 43 can drive the engaged angle adjustment transmission bevel gear II 41 to rotate. At this time, the angle adjustment transmission bevel gear II 41 can drive the angle adjustment gear 11 to rotate through the transmission shaft. Then, the rack 15 engaged with it can be driven to move. At this time, the angle adjustment bracket 12 can move simultaneously with the moving rack 15, so as to realize the pulling of the main display screen 2, and thus realize the angle adjustment of the main display screen 2;

[0080] Preferably, a drive chamber 33 is opened at a position on the lower rear side of the support column 4. The drive rod 21 passes through the inside of the drive chamber 33. Its retaining ring 28 is fixedly sleeved on the drive rod 21, and the retaining ring 28 is located at the middle position of the drive chamber 33. It can move inside the drive chamber 33 following the drive rod 21. Its stabilizing spring 29 is sleeved on the drive rod 21, and the two stabilizing springs 29 are respectively located on both sides of the retaining ring 28. The locking drive ring 30 is slidably installed on the drive rod 21 and is located behind the retaining ring 28. Its locking insertion rod 31 is installed at the upper end position of the locking drive ring 30 through a support rod. A cylindrical chamber is opened in the support column 4 corresponding to the locking insertion rod 31, and its opening faces inwards. The cylindrical chamber and the drive chamber 33 are in a communicating state. Its support rod can move back and forth inside the communicating chamber between the two. In this way, the locking insertion rod 31 can only slide back and forth under the drive of the locking drive ring 30. A plurality of locking holes 32 are opened at the back position of the angle adjustment bevel gear 19. Among them, the locking insertion rod 31 can slide back and forth to insert into and slide out of the inside of the locking holes 32;

[0081] When the bracelet 10 is released, the drive rod 21 will return to the initial position under the action of the stabilizing spring 29. The retaining ring 28 fixed on the drive rod 21 will remain stable under the action of the stabilizing springs 29 arranged on both sides. At this time, the double-sided drive bevel gear 18 will disengage from the angle adjustment bevel gear 19, so that the double-sided drive bevel gear 18 is located at the middle position between the angle adjustment bevel gear 19 and the lifting bevel gear 17, avoiding accidental rotation from causing drive adjustment to the two;

[0082] Moreover, the locking drive ring 30 will move inward under the action of the balance spring 29. At this time, the inward-moving locking drive ring 30 will drive the locking plug 31 to move inward through the support rod. Then, the inward-moving locking plug 31 will be inserted into the locking socket 32 opened on the back of the angle-adjusting bevel gear 19. At this time, the locking plug 31 can lock the rotation of the angle-adjusting bevel gear 19, thus preventing the angle-adjusting bevel gear 19 from rotating when the angle is not adjusted, and further enabling the main display screen 2 and the secondary display screen 1 to maintain the state after angle adjustment.

[0083] As Figure 3 , 10 shown, the other end of the lifting box body 40 is rotationally connected with a stabilizing runner 14 through a transmission shaft. A stabilizing bracket 13 is sleeved outside the stabilizing runner 14. One end of the stabilizing bracket 13 away from the support column 4 is rotationally connected with the back of the main display screen 2 through a support U-shaped frame 6. A plurality of stabilizing holes 16 are opened inside the stabilizing bracket 13 corresponding to the upper and lower sides of the stabilizing runner 14. A cylindrical chamber is opened inside the outer circumference of the stabilizing runner 14. A stabilizing spring 36 is fixedly arranged inside the cylindrical chamber. A stabilizing ball head 35 is fixedly connected to the outside of the stabilizing spring 36. The number of the stabilizing ball heads 35 is set to be even;

[0084] In this embodiment, the stabilizing ball heads 35 at the upper and lower ends of the stabilizing runner 14 can be snapped into the stabilizing holes 16 opened on the inner wall of the stabilizing bracket 13 under the support of the stabilizing spring 36. At this time, through the arrangement of the stabilizing holes 16 and the stabilizing ball heads 35, the damping force between the stabilizing bracket 13 and the stabilizing runner 14 can be increased, thus preventing the main display screen 2 and the secondary display screen 1 from accidentally falling due to the action of gravity when accidentally letting go during the angle adjustment process. During the angle adjustment process, due to the pulling of the stabilizing bracket 13, the stabilizing ball heads 35 can rotate and slide into different stabilizing holes 16, thereby increasing the damping feeling of the angle adjustment and preventing the occurrence of excessive angle adjustment.

[0085] Preferably, as Figure 7 , 8 shown, a pressure belt block 24 is fixedly connected to the rear side of the support slider 22. A pressing spring 39 is fixedly connected to the relative inner sides of the pressure belt block 24. A connecting pressing slider 38 is fixedly connected to the inner side of the pressing spring 39. The connecting pressing slider 38 elastically slides inside the pressure belt block 24 through the pressing spring 39.

The plurality of telescopic support legs 9 are respectively of a multi-section structure and can be stretched and shortened. A disk 20 is fixedly arranged at the outermost side of the telescopic support legs 9, and the bottom surface of the disk 20 is flush with the bottom surface of the support base 7. In this way, according to the actual use situation, the plurality of telescopic support legs 9 can be stretched, so that the contact area between the support base 7 and the bottom surface is larger, making the placement of the entire integrated display device more stable.

[0090] As another implementation manner, as Figure 1 shown, grooves are provided at the corresponding positions of the main display screen 2 and the secondary display screen 1. The rotating block 3 is located inside the grooves provided at the corresponding positions of the main display screen 2 and the secondary display screen 1. Two rotating shafts are respectively fixed on the upper and lower sides of the rotating block 3, and the four rotating shafts are respectively inserted into the shaft holes provided on the main display screen 2 and the secondary display screen 1, so that the main display screen 2 and the secondary display screen 1 can rotate through the rotating block 3. Threaded holes are provided at the positions corresponding to the rotating shafts at the lower end of the main display screen 2, and bolts 26 are screwed inside. A handle convenient for screwing is welded on the bolts 26, and the distance between the two corresponding rotating shafts is greater than the sum of the thicknesses of the main display screen 2 and the secondary display screen 1;

[0091] In this embodiment, the rotation of the secondary display screen 1 can be adjusted by the rotating block 3. When the integrated display device is not in use, the secondary display screen 1 can be rotated towards the main display screen 2, so that the secondary display screen 1 can completely cover the main display screen 2, and then the two display screens are arranged opposite to each other. In this way, the protection of the two display screens can be realized, thus avoiding damage to the display screens of the two caused by accidental collision. After the folding of the latter is completed, the bolt 26 can be screwed by the handle, and the bolt 26 can abut against the corresponding rotating shaft inside, so that the secondary display screen 1 can be prevented from rotating through the rotating shaft on the rotating block 3, thus realizing locking.
