Description

Technical Field

[0001] The present invention relates to the technical field of panel display devices, and in particular to an LCD display panel and a display device. Background Art

[0002] With the rapid development of display panels in outdoor displays and stage performances, fast installation and convenient maintenance have become standard features of their applications. Currently, display panels are often affected by environmental wind during installation and use, which poses a safety hazard, and a large amount of manpower is required during the installation of display panels.

[0003] For example, Chinese patent publication number CN117704230A discloses a wind resistance frame and LED display screen called a LED display screen, the wind resistance frame includes: a buckle assembly on the bracket; a connecting assembly installed at both ends of the bracket; and a support rod foldably installed on the bracket. By installing the buckle assembly on the bracket, the bracket and the LED display screen can be quickly installed and conveniently disassembled and repaired. When the wind resistance frame is folded, the bracket and the support rod are located on the same horizontal plane, which is convenient for transportation and carrying of the wind resistance frame. When the wind resistance frame is used, the wind resistance frame is unfolded so that the bracket and the support rod form a triangle, thereby improving the ability of the display screen to resist environmental wind force. In addition, through the setting of the connecting assembly, multiple brackets can be spliced ​​to allow multiple display screens to be spliced ​​for use.

[0004] The application supports the display screen through support rods and brackets. When not in use or transported, the support rods and brackets can be folded into a coplanar state, and the spiral sleeve and thread are located between the crossbar and the connecting component. Considering that the two support rods in the upper and lower directions need to be relatively fixed by spiral sleeves and threads, the size of the display screen to be installed needs to be specifically restricted. If the size of the display screen in the upper and lower directions is large, when the upper and lower support rods are assembled, the upper and lower displays will interfere with each other and cannot form a tight fit, which will affect the display effect after multiple display screens are spliced ​​together, and there are certain limitations on use.

[0005] Therefore, it is necessary to provide an LCD display panel and a display device to solve the above technical problems. Summary of the invention

[0016] As a further solution of the present invention: four blocks are fixedly mounted on the surface of the display screen, and a base head is rotatably mounted on the surface of the display screen; when the display screen is hung on the display device, the surface of the display screen mounting block fits with the outer surface of the auxiliary rod.

DETAILED DESCRIPTION

[0032] Embodiment 1:

[0033] See also Figures 1 to 5 The embodiment of the present invention provides an LCD display device, which is mainly used to achieve effective support and corresponding adjustment of display screens 3 with different parameters, and to make the display screens 3 fit tightly when spliced ​​for display. The device includes a plurality of support components 1 arranged in a rectangular shape, and the support components 1 are used to suspend the display screens 3 and can achieve position limiting after the display screens 3 are suspended. Among them, the support component 1 specifically includes a main rod 101, a supporting rod 105 and two auxiliary rods 102, and a housing 104 is rotatably provided on the auxiliary rod 102, the supporting rod 105 penetrates the main rod 101 and is threadedly connected thereto, and a position limiting component 2 for limiting the position of two adjacent supporting rods 105 is provided on the supporting rod 105.

[0034] In the above structure, the display screen 3 can be firstly hung on the housing 104 and fit with the outer surface of the auxiliary rod 102, and then the support rod 105 is rotated to form a threaded assembly with the seat head 5 on the display screen 3, so as to realize the support of the display screen 3 on the support assembly 1. Then, the effective limit of the two support rods 105 in the upper and lower directions can be realized through the limit assembly 2, so that the two display screens 3 in the upper and lower directions can fit tightly without interference or misalignment, so that the multiple display screens 3 in the vertical direction are aligned. Finally, the spacing between the display screens 3 and the main rod 101 can be adjusted by rotating the support rod 105, so that the multiple display screens 3 in the horizontal direction are also aligned, so that the display screens 3 are distributed in a rectangular array and are in an overall flush state.

[0035] It should be noted that in this embodiment, a seat 5 and a plurality of blocks 6 are fixedly mounted on the surface of the display screen 3 close to the main rod 101 . The blocks 6 are L-shaped and can be engaged with the housing 104 , while the seat 5 is used for threaded assembly with the support rod 105 .

[0036] Reference Figures 1 to 3In this embodiment, preferably: a crossbar 103 is installed between the main rod 101 and the auxiliary rod 102 for co-rotation, and there are two crossbars 103 located in the same horizontal plane; wherein the main rod 101, the two crossbars 103, the two auxiliary rods 102 and the housing 104 on the auxiliary rod 102 form a complete triangle when viewed from the top to the bottom. When the support rod 105 is rotated to adjust the distance between the display screen 3 and the main rod 101, the two crossbars 103 can be relatively opened / closed, thereby driving the auxiliary rod 102 to move accordingly.

[0037] In the above structure, the bottom of one cross bar 103 is recessed upward, and the top of the other cross bar 103 is recessed downward, so that the two cross bars 103 can be in the same plane. Correspondingly, the main rod 101 and the auxiliary rod 102 are both provided with a slot 106 for the placement of the cross bars 103. At the same time, in this embodiment, in order to improve the supporting effect of the auxiliary rod 102, the cross bars 103 have two groups, the upper and lower groups, and the two groups of cross bars 103 are symmetrical with the support rod 105 as the center.

[0038] In order to ensure the supporting effect of the display screen 3, the housing 104 also has two groups, and the two groups of housings 104 are also symmetrical up and down with the support rod 105 as the center; correspondingly, the number of the card blocks 6 on the surface of the display screen 3 is four. Furthermore, the housing 104 is penetrated with a slide groove 109 in the up and down direction for the placement and sliding of the card block 6. When the support rod 105 is rotated to adjust the distance between the display screen 3 and the main rod 101, the card block 6 can slide left and right along the housing 104 based on the slide groove 109.

[0039] Reference Figure 2 and Figure 5 In this embodiment, preferably, the position limiting assembly 2 includes a lower screw rod 201 and an upper screw rod 202, the lower screw rod 201 and the upper screw rod 202 are respectively threadedly sleeved on the bottom and the top of the main rod 101, and the top of the upper screw rod 202 is rotatably mounted with a rotating seat 203 that matches the diameter size of the lower screw rod 201 and is threadedly matched. When the lower screw rod 201 of the upper main rod 101 is threadedly assembled with the rotating seat 203 of the lower main rod 101, the relative position limiting of the upper and lower adjacent main rods 101 can be achieved. At the same time, through the threaded matching of the upper screw rod 202 and the lower screw rod 201 with the main rod 101, the initial positions of the lower screw rod 201 and the upper screw rod 202 based on the main rod 101 can be relatively adjusted, thereby adapting to the use of display screens 3 with different parameters.

[0040] Furthermore, a concave hole 207 is provided inside the rotating seat 203 for the lower screw rod 201 to be threadedly sleeved, and after installation, the bottom surface of the lower screw rod 201 will fit with the bottom wall of the concave hole 207. During installation, the top surface of the display screen 3 is flush with the top surface of the rotating seat 203, and the spacing between the bottom surface of the display screen 3 and the bottom surface of the lower screw rod 201 is equal to the depth dimension (up and down direction) of the concave hole 207 based on the rotating seat 203; in this way, after the upper and lower main rods 101 are limited, the upper and lower display screens 3 can fit tightly.

[0041] In this embodiment, the sum of the distance between the top surface of the main rod 101 and the top surface of the rotating seat 203 and the distance between the bottom surface of the display screen 3 and the bottom surface of the lower screw rod 201 is equal to the distance between the bottom surface of the main rod 101 and the bottom surface of the lower screw rod 201. Figure 5 The distance between the top surface of the main rod 101 and the top surface of the rotating seat 203 is the second length 205, the distance between the bottom surface of the display screen 3 and the bottom surface of the lower screw rod 201 is the third length 206, and the distance between the bottom surface of the main rod 101 and the bottom surface of the lower screw rod 201 is the first length 204.

[0042] When in use, firstly engage the block 6 of the display screen 3 in the slide groove 109 and then thread the support rod 105 and the seat head 5, then rotate the upper screw rod 202 to make the top surface of the rotating seat 203 flush with the bottom surface of the display screen 3, rotate the lower screw rod 201 to form a gap between the bottom surface of the lower screw rod 201 and the bottom surface of the display screen 3, and the gap is equal to the depth dimension of the recessed hole 207; then rotate the lower rotating seat 203 to make it threadedly cooperate with the lower screw rod 201 of the upper main rod 101, at this time, the two display screens 3 in the upper and lower directions can fit tightly.

[0043] If the two display screens 3 in the left and right directions cannot fit tightly together at this time, the support rod 105 can be rotated to adjust the spacing between the display screens 3 and the main rod 101, so that the display screens 3 correspond in the front-back direction and fit tightly together with the adjacent display screens 3 in the left and right directions quickly. In this process, the crossbar 103 can be relatively opened / closed, the auxiliary rod 102 can maintain a fit state with the display screen 3, and the housing 104 can maintain a parallel state with the surface of the display screen 3, and it is only necessary to reserve a spacing equal to the width of the display screen 3 between the two adjacent main rods 101 in the left and right directions.

[0044] When transporting and carrying, the upper screw rod 202 and the lower screw rod 201 can be rotated based on the main rod 101, so that the rotating seat 203 and the lower screw rod 201 are as close to the main rod 101 as possible. At this time, moving the two sub-rods 102 can form a state of being completely coplanar with the main rod 101, and the rotating seat 203 and the lower screw rod 201 are located between the upper and lower sets of shells 104; then the support rod 105 is rotated so that the support rod 105 is hidden in the main rod 101. At this time, the support assembly 1 can form a flat effect, which is convenient for transportation and carrying.

[0045] In summary, through the coordination of the main rod 101, the auxiliary rod 102, the support rod 105 and the rotating seat 203, the display screen 3 can be effectively supported, the positions of the rotating seat 203 and the lower screw rod 201 can be adjusted to correspond to the upper and lower surfaces of the display screen 3, and the front and rear positions of the display screen 3 relative to the main rod 101 can be adjusted, so that multiple display screens 3 can be closely fitted in the up-down direction and the left-right direction, and can be quickly adjusted to an overall flush state, so as to ensure the display effect after the multiple display screens 3 are spliced. The overall operation is simple and convenient, and it can be applied to the display of display screens 3 with different parameters, and is not limited by the parameters of the display screen 3. The disassembly and assembly efficiency of the display screen 3 is higher, and the display screen 3 can be removed by simply loosening the support rod 105 and the seat head 5, which is more practical.

[0046] Embodiment 2:

[0047] See also Figures 1 to 7 On the basis of the first embodiment, considering that the position of the card block 6 on the display screen 3 with different parameters is often different, when the display screen 3 with different parameters is applied to the display device, the card block 6 may not accurately correspond to the shell 104 and the slide groove 109, thereby affecting the support of the display device for the display screen 3 and the subsequent tight fit.

[0048] To this end, the housing 104 is improved: the outer surface of the secondary rod 102 is threadedly sleeved with an inner sleeve 110, and the housing 104 is rotatably mounted on the outer surface of the inner sleeve 110; correspondingly, an annular groove 107 is provided on the outer surface of the secondary rod 102 for the threaded lifting and lowering of the inner sleeve 110. Before the display screen 3 is suspended, the inner sleeve 110 can be rotated based on the annular groove 107 to drive the housing 104 to be lifted and lowered based on the secondary rod 102, so that the housing 104 and the slide groove 109 can form an accurate correspondence with the block 6, ensuring the subsequent support effect for the display screen 3.

[0049] Furthermore, a gear-rack reverse transmission mechanism may be provided between the two inner sleeves 110 on the same secondary rod 102. Specifically, the rack of the mechanism rotates with the inner sleeve 110 and the gear rotates with the outer surface of the secondary rod 102. The gear of the mechanism is in transmission connection with the two racks, so that when one of the inner sleeves 110 rotates, the rack can be driven to rise and fall accordingly, and then the other rack can be driven to move in the opposite direction through the gear. The gear-rack reverse transmission mechanism is an existing mature technology and will not be described in detail here.

[0050] When in use, through the structures such as the main rod 101, the auxiliary rod 102 and the rotating seat 203, it can be applied to display screens 3 with different parameters for splicing and display, and the disassembly and assembly efficiency of the display screen 3 is higher. The working process and effect of this part are the same as those in the first embodiment, and will not be repeated here. The difference is that before the display screen 3 is hung, the inner sleeve 110 can be rotated based on the annular groove 107 so that the shell 104 and the block 6 form a correspondence, so that when the display screen 3 is hung, the block 6 can be engaged in the slide groove 109 and effectively supported by the shell 104, and then the support rod 105 can be rotated to achieve effective positioning of the display screen 3.

[0051] Compared with the first embodiment, the initial position of the housing 104 relative to the auxiliary rod 102 can be freely adjusted through the cooperation of the auxiliary rod 102, the annular groove 107, the inner sleeve 110 and the gear 401 rack 402 reverse transmission mechanism, so that the housing 104 can form an accurate correspondence with the block 6 for the rapid assembly of the display screen 3. The overall solution combined with the setting of the auxiliary rod 102 can be further applied to the splicing of display screens 3 with different parameters, while still maintaining simple operation and stronger applicability.

[0052] Embodiment three:

[0053] See also Figures 1 to 9 On the basis of the second embodiment, considering that when assembling the upper and lower main rods 101, on the one hand, the position of the upper main rod 101 needs to be fixed, on the other hand, the lower screw rod 201 of the upper main rod 101 needs to be ensured not to rotate, and on the other hand, the rotating seat 203 of the lower main rod 101 needs to be rotated so that the rotating seat 203 of the lower main rod 101 forms a threaded fit with the lower screw rod 201 of the upper main rod 101. Therefore, the overall assembly process requires the participation of multiple people, resulting in relatively high costs and certain limitations in use.

[0054] To this end, the main rod 101 and the support rod 105 are improved: in this case, an adjustment component 4 corresponding to the position of the lower screw rod 201 is provided between the main rod 101 and the support rod 105. After the block 6 of the display screen 3 is engaged in the housing 104, the positions of the upper screw rod 202, the rotating seat 203 and the lower screw rod 201 are adjusted first, and then the support rod 105 is rotated to make it threadedly matched with the seat head 5. After the support rod 105 and the seat head 5 are rotated and locked for multiple turns, the adjustment component 4 can be driven to abut against the lower screw rod 201 so that the lower screw rod 201 cannot move in the up and down directions. At this time, it is only necessary to make the lower screw rod 201 of the upper main rod 101 correspond to the rotating seat 203 of the lower main rod 101, hold the upper main rod 101 with one hand, and rotate the rotating seat 203 of the lower main rod 101 with the other hand, so that the two main rods 101 can be quickly assembled.

[0055] Reference Figure 8 and Fig. 9In this embodiment, preferably, the adjustment assembly 4 includes a gear 401 rotatably mounted in the main rod 101 and keyed with the support rod 105. The gear 401 is sleeved outside the support rod 105 and can rotate synchronously with the support rod 105. When the support rod 105 reciprocates relative to the main rod 101 based on the main rod 101, the gear 401 will not reciprocate relative to the main rod 101. One side of the gear 401 is connected to a rack 402 that is slidably matched with the main rod 101, and the rack 402 corresponds to the lower screw 201. When the support rod 105 is screwed into the seat head 5, the rack 402 can be driven to descend and abut against the lower screw 201.

[0056] Correspondingly, a cavity 108 is opened inside the main rod 101 for accommodating the gear 401 and the rack 402. The rack 402 can slide up and down based on the cavity 108, and the cavity 108 is connected to the threaded hole corresponding to the lower screw rod 201, so that the rack 402 can be against the top surface of the lower screw rod 201.

[0057] In this embodiment, the length dimension of the seat head 5 along its axial direction can be increased accordingly, so that there is a deeper space inside the seat head 5 for the support rod 105 to be screwed in, and after the support rod 105 drives the rack 402 to abut against the lower screw rod 201 through the gear 401, the support rod 105 can also be guaranteed not to abut against the inner wall of the seat head 5.

[0058] When in use, through the structures such as the main rod 101, the auxiliary rod 102 and the rotating seat 203, it can be applied to the display screens 3 with different parameters for splicing display, and the disassembly and assembly efficiency of the display screen 3 is higher; through the structures such as the auxiliary rod 102, the annular groove 107 and the inner sleeve 110, the initial position of the shell 104 relative to the auxiliary rod 102 can be freely adjusted, so that the shell 104 can form an accurate correspondence with the block 6. The working process and effect of this part are the same as those in the second embodiment, and will not be repeated here. The difference is that: after the block 6 of the display screen 3 is engaged in the slide groove 109, the upper screw rod 202 and the lower screw rod 201 can be rotated so that the top surface of the rotating seat 203 is flush with the top surface of the display screen 3, so that the bottom surface of the lower screw rod 201 forms a gap with the bottom surface of the display screen 3. Then rotate the support rod 105 to make it threadedly cooperate with the seat head 5. When the support rod 105 rotates, the gear 401 drives the rack 402 to descend and abut against the lower screw 201. Then rotate the rotating seat 203 below to make it threadedly cooperate with the lower screw 201 of the upper main rod 101 (if the lower screw 201 rotates at this time, it will rise, because the lower screw 201 is limited by the rack 402, the position remains unchanged), thereby realizing the relative limitation of the two support rods 105 and the close fit of the two display screens 3 in the upper and lower directions.

[0059] When the two display screens 3 on the left and right sides are not closely attached, the support rod 105 corresponding to the protruding display screen 3 can be rotated in the opposite direction to make the display screen 3 approach the main rod 101, thereby making the two display screens 3 on the left and right sides flush with each other.

[0060] Compared with the second embodiment, through the coordination of the main rod 101, the rack 402, the gear 401 and the main rod 101, the corresponding limit of the lower screw rod 201 can be achieved when the display screen 3 is hung, so that when the rotating seat 203 is rotated and locked with the lower screw rod 201, the position of the lower screw rod 201 will not change, and then the upper support rod 105 can be held with one hand, and the rotating seat 203 of the lower support rod 105 can be rotated with the other hand to realize the process of assembling the support rod 105 and the display screen 3 by one person, which can effectively reduce the working cost. The overall solution is combined with the setting of the main rod 101 and the support rod 105, which will not affect the adjustment of the front and rear position of the display screen 3 by the rotating support rod 105, which is conducive to the rapid splicing and display of multiple display screens 3, and meets more needs in actual use.

[0061] Embodiment 4:

[0062] See also Figures 1 to 10 An embodiment of the present invention provides an LCD display panel, which is a display device used in splicing display, that is, any one of embodiments one to three is adopted, and therefore also has corresponding beneficial effects.

[0063] Among them, the LCD display panel is the display screen 3, on the surface of which a block 6 is fixedly installed to engage with the support component 1, and on the surface of the panel a seat 5 is rotatably installed to engage with the thread of the support component 1, and after the panel is hung on the display device, the surface of the panel mounting block 6 can be movably fitted with the support component 1.

[0064] Furthermore, the surface of the base 5 away from the display screen 3 and the surface of the clamping block 6 away from the display screen 3 can be arranged to be flush, which is beneficial to the overall transportation of the display screen 3 and the suspension of the display screen 3 on the display device.
