Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

Referring to fig. 1-3, the present utility model provides, in some embodiments, an adjustable flatness display screen including a case 10, a display module 50, and an adjusting unit.

The case 10 includes a side plate 12, a side adjusting hole 14 is formed in the side plate 12, an engaging member 51 is disposed on the display module 50, the engaging member 51 can be attracted to a magnetic material, and the engaging member 51 can be a magnet, an iron sheet, or the like. The display module 50 is arranged on the box body and is arranged opposite to the bottom plate 13 at intervals, the interval direction between the display module and the bottom plate 13 is the first direction, and an adjusting unit is arranged between the display module 50 and the bottom plate 13;

the adjusting unit comprises a side adjusting part and an adjusting magnet 40, the adjusting magnet 40 and the attracting piece 51 are mutually magnetically attracted, the side adjusting part is positioned in the side adjusting hole 14, the side adjusting part is in transmission fit with the adjusting magnet 40, and when external force acts on the side adjusting part, the adjusting magnet 40 can move back and forth relative to the bottom plate 13 in a first direction;

the adjusting unit further comprises a rear adjusting portion, a rear adjusting hole 15 is formed in the bottom plate 13, the rear adjusting portion corresponds to the rear adjusting hole 15, the rear adjusting portion is in transmission fit with the adjusting magnet 40, when external force acts on the rear adjusting portion through the rear adjusting hole 15, the adjusting magnet 40 can move back and forth relative to the bottom plate 13 in a first direction, and the first direction is a direction in which the adjusting magnet 40 is close to or far away from the suction piece 51.

The adjusting process of the display screen with adjustable flatness comprises the following steps: in practical applications, a complete LED display is typically formed by splicing a plurality of display modules 50. When two or more display modules 50 are spliced, if the height difference is generated, the display screen can be spliced unevenly, and the device is provided with a side adjusting process and a rear adjusting process, the side adjusting process is convenient for workers to adjust in the splicing process, the rear adjusting part is convenient for the workers to adjust after the splicing is completed, and the adjustment efficiency of the flatness of the display screen can be improved through the cooperation of the side adjusting part and the rear adjusting part.

In the side adjustment process, firstly, a worker generates a certain magnetic attraction force between the first display module 50 and the second display module 50 and the adjusting magnet 40 on the box 10 after correspondingly arranging the first display module 50 and the second display module 50, then the worker observes whether the two display modules 50 are aligned, if the flatness needs to be adjusted, the worker can directly apply an acting force to the side adjustment part arranged on the box 10 under the condition of observing the flatness between the display modules 50, then the adjusting magnet 40 matched with the side adjustment part in a transmission manner moves relative to the bottom plate 13 in the first direction, and when the adjusting magnet 40 moves, the magnetic attraction force between the adjusting magnet 40 and the adjusting magnet 51 also changes. When the distance between the adjusting magnet 40 and the engaging member 51 is closer, the magnetic attraction force between the adjusting magnet 40 and the engaging member is correspondingly larger, and the larger the magnetic attraction force is, the smaller the distance between the display module 50 and the bottom plate 13 is; the farther the distance between the adjusting magnet 40 and the engaging member 51 is, the smaller the magnetic attraction force therebetween becomes, so that the distance between the display module 50 and the bottom plate 13 becomes larger. Therefore, the adjusting magnet 40 is driven to displace by the side adjusting part, so as to realize the adjustment of the flatness of the display screen.

Specifically, after the worker attaches the first display module 50 to the case 10, the worker uses the position thereof as an adjustment reference, i.e., the position of the first display module 50 remains unchanged. The worker continuously attaches the second display module 50 to the box 10 and completes the splicing with the first display module 50, then the worker can directly apply a first acting force to the side adjusting part on the box 10 when observing that the height of the second display module 50 is lower than that of the first display module 50, the first acting force drives the adjusting magnet 40 to move in the direction away from the suction piece 51, when the distance between the adjusting magnet 40 and the suction piece 51 becomes larger, the magnetic attraction between the adjusting magnet 40 and the suction piece 51 is reduced, the second display module 50 is far away from the bottom plate 13 due to the reduction of the magnetic attraction, and the second display module 50 is flush with the first display module 50; similarly, if the worker considers that the height of the second display module 50 is higher than that of the first display module 50 by observation, the worker applies a second force to the side adjusting portion on the case 10, the second force drives the adjusting magnet 40 to move in a direction approaching the engaging member 51, and when the distance between the adjusting magnet 40 and the engaging member 51 becomes smaller, the magnetic attraction force between the adjusting magnet 40 and the engaging member 51 becomes larger, and the second display module 50 approaches the bottom plate 13 due to the increase of the magnetic attraction force until the second display module 50 is flush with the first display module 50. In the adjustment process, whether the adjustment is in a flat state or not can be directly observed, and the adjustment state can be realized while the adjustment is observed, so that the adjustment efficiency is high compared with the traditional adjustment mode of completely removing and then returning the adjustment by a worker who winds the rear side of the display module 50 after the traditional display module 50 is completed.

In the post-adjustment process, when the display module 50 is fully attached to the attaching surface of the case 10, the middle portion of the finished display screen cannot be adjusted in flatness by the side adjustment portion. At this time, if the worker observes that the place where the flatness is required to be adjusted can be adjusted by the rear adjusting part, the rear adjusting part is supplemented and optimized for the opposite side adjusting part, so that the high flatness of the box 10 is ensured, and the flatness adjusting efficiency of the worker is improved.

Specifically, when a worker observes that a certain display module 50 in the middle of the finished display screen has a protrusion or depression, the position or height of the display module can be adjusted through the bottom plate 13 of the case 10 and the rear adjustment hole 15 corresponding thereto. When the middle display module 50 is lower than other surrounding display modules 50, a worker operates a tool to pass through the rear adjusting hole 15, applies a force for driving the adjusting magnet 40 to be far away from the attraction piece 51 to the rear adjusting part, and the magnetic attraction between the adjusting magnet 40 and the attraction piece 51 is correspondingly reduced due to the increase of the distance between the adjusting magnet 40 and the attraction piece 51, so that the distance between the concave display module 50 and the bottom plate 13 is increased due to the decrease of the magnetic attraction until the concave display module 50 is level with other display modules 50; similarly, when the middle display module 50 is higher than the surrounding other display modules 50, after the worker passes through the rear adjustment hole 15, the force for driving the adjustment magnet 40 to approach the engaging member 51 is applied to the rear adjustment portion, the distance between the adjustment magnet 40 and the engaging member 51 is reduced, so that the magnetic attraction between the adjustment magnet 40 and the engaging member 51 is correspondingly increased, and the distance between the convex display module 50 and the bottom plate 13 is reduced due to the increase of the magnetic attraction until the convex display module 50 is flush with the other display modules 50.

In some embodiments, the adjustment unit further comprises a rear adjustment member 20 and a side adjustment member 30, the rear adjustment member 20 comprising a rear adjustment portion, and the rear adjustment portion belonging to an end of the rear adjustment member 20 adjacent to the rear adjustment aperture 15, the side adjustment member 30 comprising a side adjustment portion, and the side adjustment portion belonging to an end of the side adjustment member 30 adjacent to the suction member 51;

In the present embodiment, when a worker applies a force to the side regulating portion, the side regulating member 30 can rotate the regulating magnet 40 installed inside thereof together with the rear regulating member 20 rotatably connected outside, thereby realizing displacement of the regulating magnet 40. Alternatively, when a worker applies a force to the rear adjustment portion through the rear adjustment hole 15, the rear adjustment member 20 can rotate the side adjustment member 30 and the adjustment magnet 40 disposed inside thereof with respect to the case 10, thereby driving the adjustment magnet 40 to complete displacement.

Further, in some embodiments, the adjustment magnet 40 is located within the side adjustment member 30 and the side adjustment member 30 is rotatably connected to the rear adjustment member 20, such that when a worker applies a force to the side adjustment member, the side adjustment member 30 is able to rotate the adjustment magnet 40 mounted therein relative to the rear adjustment member 20 (when the rear adjustment member 20 is relatively stationary), thereby effecting displacement of the adjustment magnet 40. The rear adjusting member 20 is rotatably connected with the case 10, and when a worker applies a force to the rear adjusting portion through the rear adjusting hole 15, the rear adjusting member 20 can drive the side adjusting member 30 and the adjusting magnet 40 provided inside thereof to rotate with respect to the case 10, thereby driving the adjusting magnet 40 to complete displacement.

The suction force between the adjusting magnet 40 and the attracting piece 51 also changes along with the displacement of the adjusting magnet 40, so that the position or the height of the display module 50 where the attracting piece 51 is located is adjusted, and further flatness adjustment between the display modules 50 is achieved.

In this embodiment, the rear adjusting member 20 and the side adjusting member 30 are designed to be split, which is conducive to assembly, disassembly, maintenance and replacement of subsequent parts, so that the device is more flexible in design and more universal. In other embodiments, the rear adjuster 20 and the side adjuster 30 may also be of unitary design.

In some embodiments, the rear adjuster 20 and the side adjuster 30 are each cylindrical in shape with one end open and the other end closed; one end of the rear adjusting member 20, which is close to the engaging member 51, is an open end of the rear adjusting member 20, one end of the rear adjusting member 20, which is close to the rear adjusting hole 15, is a closed end of the rear adjusting member 20, the side adjusting member 30 can be inserted into the side adjusting member 30 from the open end of the rear adjusting member 20, and the side adjusting member 30 can be displaced along a first direction relative to the rear adjusting member 20, and the rear adjusting portion is a closed end of the rear adjusting member 20;

one end of the side adjusting piece 30, which is close to the rear adjusting hole 15, is an opening end of the side adjusting piece 30, one end of the side adjusting piece 30, which is close to the suction piece 51, is a closed end of the side adjusting piece 30, and the side adjusting part belongs to the closed end of the side adjusting piece 30; an adjustment magnet 40 is provided at the closed end of the side adjustment member 30.

In this embodiment, the rear adjusting member 20 and the side adjusting member 30 are of split type, and are both of a cylindrical shape with one end open and one end closed, and this arrangement can facilitate the placement and removal of the adjusting magnet 40 when assembling or disassembling the parts, increasing the practicality of the device.

In some embodiments, the case 10 is provided with an adjusting groove 11, the rear adjusting member 20 is screwed with a groove wall of the adjusting groove 11, the side adjusting member 30 is screwed with the rear adjusting member 20, and a screwing direction of the screw connection is parallel to the first direction. The damping between the rear adjuster 20 and the adjusting groove 11 is greater than the damping between the side adjuster 30 and the rear adjuster 20.

In this embodiment, when the operator applies the first force to the side adjusting portion to drive the side adjusting member 30 and the adjusting magnet 40 inside thereof to rotate relative to the rear adjusting member 20, since the damping between the rear adjusting member 20 and the adjusting groove 11 is greater than the damping between the side adjusting member 30 and the rear adjusting member 20, the first force is unable to drive the rear adjusting member 20 to rotate relative to the adjusting groove 11, the side adjusting member 30 and the adjusting magnet 40 inside thereof can rotate relative to the rear adjusting member 20 and displace, and the rear adjusting member 20 remains stationary relative to the case 10, thereby completing the side adjusting process.

When the operator applies a second acting force to the rear adjusting portion, the second acting force drives the rear adjusting member 20 to rotate relative to the case 10, the rear adjusting member 20 can rotate relative to the case 10, and then the side adjusting member 30 and the adjusting magnet 40 are driven to displace, thereby completing the rear adjusting process.

Specifically, the worker can apply the first force to the side adjustment portion by his own hand force, and the worker can apply the second force to the rear adjustment portion by using a tool. The design is convenient for workers to timely and rapidly adjust the flatness in the process of attaching and installing the unit display screen, and improves the efficiency of adjusting the flatness. And when all the unit display screens are spliced, workers can correspondingly adjust part of the display screens through the rear adjusting part by means of tools. The flatness of the whole screen is ensured in two aspects.

In some embodiments, the number of the rear adjusting members 20, the side adjusting members 30, the adjusting grooves 11, and the adjusting magnets 40 corresponding to one of the display modules 50 is six, and are uniformly distributed on the case 10.

Referring to fig. 3, a display module 50 has six corresponding side adjustment positions and rear adjustment positions on the case 10, and in the practical application process, when two display modules 50 are spliced and attached to the case, the adjustment accuracy of the display screen can be improved by performing side adjustment on the periphery of the two display modules 50, so as to realize adjustment of the flatness of the display screen. Similarly, when the plurality of display modules 50 are assembled in sequence, an operator can perform side adjustment on the periphery of the display screen after the assembly is completed.

In some embodiments, the side adjustment member 30 includes an adjustment gear 32, the adjustment gear 32 rotating relative to the rear adjustment member 20 about a first axis that is parallel to the first direction, with a portion of the gear teeth of the adjustment gear 32 being located within the side adjustment aperture 14 and a portion of the gear teeth being located within the side adjustment aperture 14.

In this embodiment, the operator applies a force to the adjustment gear 32 to drive the adjustment gear 32 to rotate in the first and second directions. When the adjusting gear 32 rotates in the first direction, the side adjusting member 30 and the adjusting magnet 40 move in a direction approaching the engaging member 51, and when the adjusting gear 32 rotates in the second direction, the side adjusting member 30 and the adjusting magnet 40 move in a direction separating from the engaging member 51.

Further, the design of the adjusting gear 32 also facilitates the operator to apply a force to the side adjusting member 30, saving the operator's adjustment time and effort.

In some embodiments, the rear adjustment portion is provided with an adjustment notch 23, the adjustment notch 23 corresponds to the rear adjustment hole 15, the adjustment notch 23 may be a through hole formed through the rear adjustment portion, or a groove formed by recessing on the rear adjustment portion, and the shape of the adjustment notch 23 may be set to different shapes, such as a circle, a polygon, a star, an S-shape, etc., as required. Preferably polygonal, for example triangular, quadrangular, pentagonal or hexagonal.

The operator inserts the instrument through the back regulation hole 15 and adjusts breach 23, then twists the instrument and drives back regulating part 20 rotation, realizes the back adjustment process of display screen. The design of the adjusting notch 23 can be determined according to actual production requirements, and different adjusting notches 23 correspond to different adjusting tools. The adjusting notch 23 of triangle, quadrangle, pentagon and hexagon adopts the internal triangle spanner, the internal quadrangle spanner, the internal pentagon spanner and the internal hexagonal spanner to carry out adjusting operation.

In some embodiments, the adjusting magnet 40 is slidably connected to the side adjusting member 30, the sliding direction of the adjusting magnet 40 in the side adjusting member 30 is the same as the first direction, and when the adjusting magnet 40 slides to the end of the side adjusting member 30 near the engaging member 51, the side adjusting member 30 is at least partially limited to the side of the adjusting magnet 40 near the engaging member 51.

In this embodiment, when the display module 50 needs to be replaced and maintained, a worker needs to detach the display module 50 from the case 10, that is, needs to separate the adjusting magnet 40 from the engaging member 51, at this time, the worker can use a magnetic tool (for example, detach the magnet), place the same pole side of the detaching magnet and the adjusting magnet 40 above the engaging member 51, by opposite the same pole of the detaching magnet and the adjusting magnet 40, because the magnets have the principle of like poles repel each other and attract each other, and the repulsive force between the detaching magnet and the adjusting magnet 40 is greater than the attractive force between the adjusting magnet 40 and the engaging member 51, so that the detaching magnet can easily offset the attractive force between the adjusting magnet 40 and the engaging member 51, and the adjusting magnet 40 is separated from the engaging member 51 by the repulsive force, so that the worker can easily take out the display module 50 connected with the case 10, not only improving the detaching efficiency of the worker for the display screen, but also avoiding the damage to the display screen in the detaching process.

In some embodiments, the side of the conditioning magnet 40 remote from the pull-in member 51 is provided with a buffer pad 60. The cushion pad 60 is preferably made of a flexible material such as rubber or silicone rubber.

When the display module 50 needs to be disassembled, the adjusting magnet 40 needs to be displaced by using the repulsive force of the same polarity, and the buffer pad 60 is disposed on the other side of the adjusting magnet 40 away from the engaging member 51, so that the adjusting magnet 40 is prevented from being excessively displaced and colliding with the rear adjusting member 20, thereby damaging the adjusting magnet 40.
