Description

Technical Field

[0001] The invention relates to the technical field of display screens, and in particular to a standardized module strip display screen. Background Art

[0002] Existing display screens have the following two problems that restrict display quality:

[0003] One is the problem of display screen flatness. Due to the unevenness of the module frame installation surface, the display screen surface is uneven. At present, the existing display screen structure box is usually made of aluminum alloy die-casting box. After the die-cast blank is formed, the module installation surface is finely processed by CNC machine tools to ensure the display flatness of the display screen. The entire production and processing process is complicated and costly.

[0004] The other is the problem of display screen seams. The existing strip display screens usually use screws to fix the light bar modules to the frames at both ends of the box. After multiple strip modules are assembled on the box, the gap between the modules depends on the straightness of the side of the light bar module. When the light bar module is long and curved, it will cause uneven gaps between adjacent modules after the box is spliced, thus affecting the display effect of the box. In addition, when multiple strip modules are spliced, the total width of the required display screen is certain, and the spacing between the strip modules is not easy to control evenly, which will cause multiple seams on the display screen to be of different sizes, affecting the quality of the display screen. Summary of the invention

[0005] The purpose of the present invention is to solve the problems existing in the above-mentioned prior art and to provide a standardized module strip display screen, which has high surface flatness, uniform joint sizes between modules, guaranteed display quality of the display screen, and low processing cost.

[0006] The objective of the present invention is achieved through the following technical solutions:

[0007] A standardized module strip display screen comprises a plurality of module frames spliced ​​in sequence, a module arranged on the module frames, and two crossbeams arranged at both ends of the plurality of module frames, the crossbeams are provided with a plurality of groups of positioning pins with the same intervals, and a group of positioning holes is arranged on the bottom plate of the module frame;

[0008] The module frame includes a main frame and an adjusting member, the main frame includes an integrally formed bottom plate and two side plates arranged opposite to each other, one end of the side plate away from the bottom plate is provided with a slot, and one end of the adjusting member is inserted into the slot;

[0009] A slide groove is provided on the side of the module frame, and limit strips are provided on both sides of the slide groove opening, and a seam adjustment structure and / or a flatness adjustment structure are provided between the opposite slide grooves;

[0010] The joint adjustment structure comprises two sliders respectively arranged in the two slide grooves, and a screw threadedly connecting the two sliders;

[0011] The flatness adjustment structure includes the slider disposed in one of the slide grooves, and a conical head screw threadedly connected to the slider, wherein the conical head of the conical head screw conflicts with the limiting strip.

[0012] The design and installation principle of the present invention:

[0013] Regarding the control of the flatness of the display screen: On the one hand, since the structure of the main frame is relatively complex and larger, the straightness or flatness of the connecting surface of the side panel is not easy to ensure; while the structure of the adjustment member is simple, it is a long strip profile, which is easy to straighten, and its straightness or flatness is relatively easy to ensure, so during processing, the present invention only needs to ensure the straightness or flatness of the adjustment member, and the difficulty and cost will be greatly reduced. During installation, by measuring and adjusting the depth of each part of the adjustment member inserted into the slot in the length direction, the distance from each part of the bottom plate to the installation surface of the adjustment member is within the required size and error range, and then the adjustment member is fixed to the slot by fixing glue or other methods. On the other hand, if there is still a partial flatness problem after implementing the above method, the conical head screw can be screwed into the slider for a certain length on the outside according to the measurement data, and then the slider is slid into the slide groove from the end of one module frame and moved to the position that needs to be adjusted, and then the other module frame is assembled from one side. During the assembly process, as the conical head of the conical head screw is gradually inserted between the two limit bars, the slide grooves or limit bars of the two adjacent module frames are pulled to the same horizontal height at this location, that is, the surfaces of the two module frames are at the same horizontal height at this location. Of course, if the two module frames have been assembled in advance, auxiliary tools can also be used to move the entire adjustment structure to the required position. The auxiliary tools can be rod-shaped tools that push the slider from the end of the module frame, or sheet-shaped tools that are inserted from the joints between adjacent module frames to pull the conical head screw. In addition, after the entire adjustment structure is moved to the designated position, if the surface heights of adjacent module frames are still significantly different due to insufficient insertion length of the conical head, a flat wrench can be inserted into the joint and the conical head screw can be rotated to adjust the insertion length of the conical head, thereby adjusting the flatness. Of course, this adjustment method requires that the middle part of the conical head screw be processed into a polygonal shape to facilitate the operation of the wrench.

[0014] Regarding the control of the seams of the display screen: On the one hand, the installation position of each strip module is accurately located through multiple sets of positioning pins with consistent spacing on the beam, thereby ensuring that the spacing of multiple seams is consistent. On the other hand, first connect the two sliders with screws on the outside, and adjust the distance between the two sliders according to the measurement data, and then slide the two sliders into the two opposite slide grooves from the ends of the adjacent module frames, and then use auxiliary tools to slide the entire adjustment structure to the position where the seam needs to be adjusted. Under the pulling or pushing action of the two sliders, the seam that was originally too large or too small can be adjusted. Among them, the auxiliary tool can be a rod-shaped tool that pushes the slider from the end of the module frame, or it can be a sheet-shaped tool that is inserted into the seam between adjacent module frames to pull the screw. In addition, when the entire adjustment structure moves to the specified position, if the size of the joint does not meet the requirements, a sheet wrench can be inserted into the joint and the screw can be rotated to adjust the distance between the two sliders to adjust the size of the joint. Of course, this adjustment method requires the middle part of the screw to be processed into a polygonal shape to facilitate the operation of the wrench; and the thread directions at both ends of the screw need to be opposite so that when the screw rotates, the sliders at both ends can be moved closer or separated at the same time.

[0015] As a preferred embodiment of the present invention, the cross beam and the bottom plate of the module frame are also provided with matching fixing holes, which are used to fix the module frame and the cross beam.

[0016] As a preferred embodiment of the present invention, an "L"-shaped strip is provided inside the end of the side panel, and the slot is formed between the "L"-shaped strip and the side panel. The slot is provided inside the main frame to avoid affecting the splicing of multiple main frames.

[0017] As a preferred embodiment of the present invention, the adjusting member includes an integrally formed main body, a plug-in portion and a module connecting portion, wherein the plug-in portion and the module connecting portion are arranged at both ends of the main body. The adjusting member has a simple structure, wherein the main body ensures structural strength and stability, the plug-in portion is used for matching the slot installation, and the module connecting portion is used for module installation connection.

[0018] As a preferred embodiment of the present invention, the thickness of the main body is greater than the thickness of the plug-in portion. The thickness of the main body is greater in order to ensure the structural strength and stability of the entire adjusting member.

[0019] As a preferred embodiment of the present invention, the thickness of the module connection part is smaller than the thickness of the main body part. The module connection part has a smaller thickness in order to reduce the contact area with the module, thereby reducing the influence of the unevenness of the module connection part mounting surface on the module flatness.

[0020] As a preferred embodiment of the present invention, the module connection part is arranged in the extension direction of the side plate. The design enables the pressure from the module received by the module connection part to be stably transmitted to the side plate, avoiding deformation caused by transmitting the pressure to the slot.

[0021] As a preferred embodiment of the present invention, the cross section of the slide groove is a trapezoidal shape with a wide outer side and a narrow inner side, and the slider has a shape adapted to the slide groove. The outer side of the slide groove is wide to ensure that the limit bar has a sufficient width, thereby ensuring the limit bar has a limiting effect on the slider; the inner side of the slide groove is narrow, which can save materials and reduce weight, and at the same time make the slider adapted to its shape lighter, thereby reducing the impact of adding an adjustment structure on the weight of the entire display screen.

[0022] As a preferred embodiment of the present invention, the screw includes an operating portion in the middle and threaded portions at both ends, and the thread directions of the two threaded portions are opposite. The structure makes it easy to insert a sheet wrench through the joint to rotate the screw to adjust the distance between the two sliders after the entire adjustment structure is moved to a designated position of an adjacent module frame.

[0023] As a preferred embodiment of the present invention, the slider is further provided with a fastening threaded hole. The fastening threaded hole is used to cooperate with the screw to fasten the slider at a specified position. Specifically, when used as a slider of a flatness adjustment structure, the slider can be directly moved to a specified position to be fixed, and then the module frame can be assembled; when used as a slider of a joint adjustment structure, a screw can be pre-installed at the fastening threaded hole on the outside, and after the slider slides to the specified position, a sheet wrench is inserted into the joint of the adjacent module frame, and the screw (hexagonal screw) is turned to fasten the slider to prevent it from accidentally sliding.

[0024] The advantages of the present invention are simple structure, convenient installation, and the ability to effectively ensure the flatness of the display screen surface and uniform joint sizes between modules, thereby ensuring the display quality of the display screen, while having low processing costs.

DETAILED DESCRIPTION

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0035] A standardized module strip display screen comprises a plurality of module frames 1 spliced ​​in sequence, a module 2 arranged on the module frames 1, and two crossbeams 3 arranged at both ends of the plurality of module frames 1, the crossbeams 3 are provided with a plurality of groups of positioning pins 31 with the same intervals, and a group of positioning holes are arranged on the bottom plate of the module frame 1; the module frame 1 comprises a main frame 11 and an adjusting member 12, the main frame 11 comprises an integrally formed bottom plate 111 and two side plates 112 arranged oppositely, the side plates 112 are provided with a slot 113 at one end away from the bottom plate 111, and the adjusting member 12 is provided with a slot 113. One end of the section 12 is inserted into the slot 113; a slide groove 4 is provided on the side of the module frame 1, and limit strips 5 are provided on both sides of the slide groove 4, and a seam adjustment structure and / or a flatness adjustment structure is provided between the opposite slide grooves 4; the seam adjustment structure includes two sliders 6 respectively arranged in the two slide grooves 4, and a screw 7 threadedly connected to the two sliders 6; the flatness adjustment structure includes the slider 6 arranged in one of the slide grooves 4, and a conical head screw 8 threadedly connected to the slider 6, and the conical head 81 of the conical head screw 8 conflicts with the limit strip 5.

[0036] The design and installation principle of the present invention:

[0037] Regarding the control of the flatness of the display screen: On the one hand, since the structure of the main frame is relatively complex and larger, the straightness or flatness of the connecting surface of the side panel is not easy to ensure; while the structure of the adjustment member is simple, it is a long strip profile, which is easy to straighten, and its straightness or flatness is relatively easy to ensure, so during processing, the present invention only needs to ensure the straightness or flatness of the adjustment member, and the difficulty and cost will be greatly reduced. During installation, by measuring and adjusting the depth of each part of the adjustment member inserted into the slot in the length direction, the distance from each part of the bottom plate to the installation surface of the adjustment member is within the required size and error range, and then the adjustment member is fixed to the slot by fixing glue or other methods. On the other hand, if there is still a partial flatness problem after implementing the above method, the conical head screw can be screwed into the slider for a certain length on the outside according to the measurement data, and then the slider is slid into the slide groove from the end of one module frame and moved to the position that needs to be adjusted, and then the other module frame is assembled from one side. During the assembly process, as the conical head of the conical head screw is gradually inserted between the two limit bars, the slide grooves or limit bars of the two adjacent module frames are pulled to the same horizontal height at this location, that is, the surfaces of the two module frames are at the same horizontal height at this location. Of course, if the two module frames have been assembled in advance, auxiliary tools can also be used to move the entire adjustment structure to the required position. The auxiliary tools can be rod-shaped tools that push the slider from the end of the module frame, or sheet-shaped tools that are inserted from the joints between adjacent module frames to pull the conical head screw. In addition, after the entire adjustment structure is moved to the designated position, if the surface heights of adjacent module frames are still significantly different due to insufficient insertion length of the conical head, a flat wrench can be inserted into the joint and the conical head screw can be rotated to adjust the insertion length of the conical head, thereby adjusting the flatness. Of course, this adjustment method requires that the middle part of the conical head screw be processed into a polygonal shape to facilitate the operation of the wrench.

[0038] Regarding the control of the seams of the display screen: On the one hand, the installation position of each strip module is accurately located through multiple sets of positioning pins with consistent spacing on the beam, thereby ensuring that the spacing of multiple seams is consistent. On the other hand, first connect the two sliders with screws on the outside, and adjust the distance between the two sliders according to the measurement data, and then slide the two sliders into the two opposite slide grooves from the ends of the adjacent module frames, and then use auxiliary tools to slide the entire adjustment structure to the position where the seam needs to be adjusted. Under the pulling or pushing action of the two sliders, the seam that was originally too large or too small can be adjusted. Among them, the auxiliary tool can be a rod-shaped tool that pushes the slider from the end of the module frame, or it can be a sheet-shaped tool that is inserted into the seam between adjacent module frames to pull the screw. In addition, when the entire adjustment structure moves to the specified position, if the size of the joint does not meet the requirements, a sheet wrench can be inserted into the joint and the screw can be rotated to adjust the distance between the two sliders to adjust the size of the joint. Of course, this adjustment method requires the middle part of the screw to be processed into a polygonal shape to facilitate the operation of the wrench; and the thread directions at both ends of the screw need to be opposite so that when the screw rotates, the sliders at both ends can be moved closer or separated at the same time.

[0039] Specifically, the crossbeam 3 and the bottom plate of the module frame 1 are also provided with matching fixing holes 9. The fixing holes are used to fix the module frame and the crossbeam. The crossbeam 3 is specifically an angle steel, one plate of which is provided with the positioning pin 31, and the width of the other plate is equal to the thickness of the display screen. On the one hand, the structural strength of the angle steel is higher, and on the other hand, the other plate of the angle steel can also be used as a closed structure at the end of the module frame.

[0040] In addition, an "L"-shaped strip profile 114 is provided on the inner side of the end of the side plate, and the slot 113 is formed between the "L"-shaped strip profile 114 and the side plate 112. The slot is set inside the main frame to avoid the influence on the splicing of multiple main frames. The adjustment member 12 includes an integrally formed main body 121, a plug-in part 122 and a module connecting part 123, and the plug-in part 122 and the module connecting part 123 are respectively arranged at both ends of the main body 121. The structure of the adjustment member is simple, wherein the main body ensures structural strength and stability, the plug-in part is used for matching the slot installation, and the module connecting part is used for the installation and connection of the module. The thickness of the main body 122 is greater than the thickness of the plug-in part 122. The thickness of the main body is greater, in order to ensure the structural strength and stability of the entire adjustment member. The thickness of the module connecting part 123 is less than the thickness of the main body 121. The thickness of the module connection part is smaller in order to reduce the contact area with the module, thereby reducing the impact of the unevenness of the module connection part mounting surface on the module flatness. The module connection part 123 is arranged in the extension direction of the side plate 112. The design enables the pressure from the module received by the module connection part to be stably transmitted to the side plate, avoiding deformation caused by transmitting the pressure to the slot.

[0041] The cross section of the slide 4 is a trapezoid with a wide outer side and a narrow inner side, and the slider 6 has a shape adapted to the slide. The outer side of the slide is wide to ensure that the limit bar has a sufficient width, thereby ensuring the limit bar's limiting effect on the slider; the inner side of the slide is narrow, which can save materials and reduce weight, and at the same time make the slider adapted to its shape lighter, thereby reducing the impact of increasing the weight of the adjustment structure on the entire display screen. The screw 7 includes a middle operating portion 71 and threaded portions 72 at both ends, the thread directions of the two threaded portions 72 are opposite, and the cross section of the operating portion 71 is a polygon. The structure makes it easy to insert a sheet wrench from the joint to rotate the screw to adjust the distance between the two sliders after the entire adjustment structure moves to the designated position of the adjacent module frame. Similarly, the middle part of the conical head screw is also polygonal to facilitate the operation of the sheet wrench. The slider 6 is also provided with a fastening threaded hole 61. The fastening threaded hole is used to cooperate with the screw to fasten the slider in the specified position. Specifically, when it is used for the slider of the flatness adjustment structure, the slider can be directly moved to the specified position to fix it, and then the module frame can be assembled; when it is used for the slider of the joint adjustment structure, the screw can be pre-installed at the fastening threaded hole on the outside, and after the slider slides to the specified position, a sheet wrench is inserted from the joint of the adjacent module frame, and the screw (hexagonal screw) is turned to fasten the slider to prevent it from accidentally sliding. The module frame 1 is provided with an adjustment groove 10 on the outside of the limit strip 5. The adjustment groove is mainly used to accommodate screws and conical head screws to facilitate relevant adjustment operations.
