[0008] In one embodiment, the splicing and positioning surface includes a first splicing reference surface and a second splicing reference surface, and the first splicing reference surface and the second splicing reference surface are respectively located on both sides of the angle block in the first direction.

[0009] In one embodiment, any one of the first splicing reference surface and the second splicing reference surface forms the first included angle with the first installation positioning surface.

[0010] In one embodiment, any one of the first splicing reference surface and the second splicing reference surface forms the second included angle with the second installation positioning surface.

First limiting steps and locking plates that are spaced apart in the first direction are convexly provided on the inner wall of the mounting hole, and the locking plates have locking holes.

[0015] In one embodiment, the locking hole has a first hole diameter in a first radial direction and a second hole diameter in a second radial direction, and the first hole diameter and the second hole diameter are different.

[0016] In one embodiment, a second limiting step is convexly provided on the inner wall of the mounting hole, and the first limiting step and the second limiting step are respectively located on both sides of the locking plate.

The angle block is positioned and installed on the first display unit through the first installation positioning surface or the second installation positioning surface, and abuts against the second display unit through the splicing positioning surface, thereby defining the splicing angle of the second display unit relative to the first display unit. When the angle block is positioned and installed on the first display unit through the first installation positioning surface, the splicing angle between the two display units is the first angle. When the angle block is positioned and installed on the first display unit through the second installation positioning surface, the splicing angle between the two display units is the second angle. Since the first angle and the second angle are different, the splicing angle between the two display units can be adjusted.

The static positioning surface is stable and reliable, solving the technical problem of poor stability existing in the existing angle splicing structure, greatly simplifying the structure, reducing the number of components, and reducing the manufacturing cost and maintenance cost.

[0047] Embodiment 1

[0048] Combined with Figure 1 and Figure 2 , the present application provides an angle block 100. The angle block 100 is used for splicing adjacent display units 10 in the first direction X. The angle block 100 has a first installation and positioning surface 110, a second installation and positioning surface 120, and a splicing positioning surface 130 facing the first direction X. Any one of the first installation and positioning surface 110 and the second installation and positioning surface 120 is used for the installation and positioning of the angle block 100 in the first display unit 10. A first included angle is formed between the first installation and positioning surface 110 and the splicing positioning surface 130, and a second included angle is formed between the second installation and positioning surface 120 and the splicing positioning surface 130. The first included angle and the second included angle are different, that is, the first installation and positioning surface 110 and the second installation and positioning surface 120 are not parallel and there is an included angle between them. The splicing positioning surface 130 is used for the angle block 100 to abut against the second display unit 10.

[0049] Please also combine Figure 3 and Figure 4 , adjacent display units 10 are spliced in the first direction X. The angle block 100 is positioned and installed on the first display unit 10 through the first installation and positioning surface 110 or the second installation and positioning surface 120, and abuts against the second display unit 10 through the splicing positioning surface 130, thereby defining the splicing angle of the second display unit 10 relative to the first display unit 10. Reference can be made to Figure 5 and Figure 6 . When the angle block 100 is positioned and installed on the first display unit 10 through the first installation and positioning surface 110, the splicing angle between the two display units 10 is the first angle. Reference can be made to Figure 7 and Figure 8 . When the angle block 100 is positioned and installed on the first display unit 10 through the second installation and positioning surface 120, the splicing angle between the two display units 10 is the second angle. Since the first angle and the second angle are different, the splicing angle between the two display units 10 can be adjusted.

[0050] Compared with relying on motion mechanisms such as worm gears, rack and pinions, or slider chutes, the angle block 100 restricts the two display units 10 to form different splicing angles through the static first installation positioning surface 110, second installation positioning surface 120, and splicing positioning surface 130, without the need for additional power adjustment, that is, without setting power components and transmission components, etc., reducing errors and unstable factors caused by mechanical transmission. The static positioning surface is stable and reliable, greatly simplifying the structure, reducing the number of components, and lowering the manufacturing cost and maintenance cost.

[0051] In some embodiments, in combination with Figure 1 and Figure 2 , the angle block 100 is integrally formed. The angle block 100 has only one component, with a small number of components. There is no problem of loose connection or relative movement between components resulting in deviations in the first installation positioning surface 110, second installation positioning surface 120, and splicing positioning surface 130, greatly improving the stability and reliability of the angle block 100 during the splicing process of the display unit 10. The integrally formed angle block 100 has good integrity, no assembly error, high position accuracy, and does not require assembly, being convenient and fast to assemble on the display unit 10, which is conducive to improving the on-site splicing efficiency.

[0052] Optionally, the angle block 100 is integrally injection molded, integrally die cast, or integrally machined, which is not limited herein.

[0053] In some embodiments, in combination with Figure 3 and Figure 4 , the angle block 100 is positioned and installed on one side of the display unit 10 in the first direction X, and the splicing positioning surface 130 of the angle block 100 is exposed, facilitating another display unit 10 to abut against the splicing positioning surface 130.

[0054] Specifically, the display screen further includes a first locking mechanism 200 and a second locking mechanism 30. The first locking mechanism 200 is installed on the first display unit 10 and fixes the angle block 100 to the first display unit 10. The second display unit 10 abuts against the splicing positioning surface 130. The second locking mechanism 30 is installed on the second display unit 10 and is fixedly connected to the angle block 100 to achieve fixed splicing of the two display units 10.

[0055] Optionally, the first locking mechanism 200 and the second locking mechanism 30 are located on both sides of the display unit 10 in the first direction X, so that the sides of adjacent two display units 10 can achieve angle-adjustable splicing through the angle block 100, the first locking mechanism 200, and the second locking mechanism 30.

[0056] In some embodiments, in combination with Figure 3 and Figure 4, the display unit 10 has a mounting groove 11, and the angle block 100 is limited in the mounting groove 11, realizing the installation of the angle block 100 on the display unit 10. One side wall of the mounting groove 11 in the first direction X has a positioning groove wall 12. Both the first mounting positioning surface 110 and the second mounting positioning surface 120 can individually abut against the positioning groove wall 12, realizing that the installation angle of the angle block 100 on the display unit 10 is adjustable. Furthermore, the splicing positioning surface 130 is adjustable in angle relative to the first display unit 10. When another display unit 10 is spliced, it is based on the splicing positioning surface 130, thereby realizing that the splicing angle of the two display units 10 is adjustable.

[0057] Optionally, the mounting groove 11 has an opening on the side close to the outside in the first direction X, and the splicing positioning surface 130 of the angle block 100 is located in this opening, so as to facilitate abutting against another display unit 10.

[0058] Optionally, the positioning groove wall 12 is located on the side of the mounting groove 11 close to the outside in the first direction X, and the first fastening mechanism 200 is located on the side of the mounting groove 11 close to the inside. Thus, the first fastening mechanism 200 presses and fixes the angle block 100 in the mounting groove 11 from the inside and abuts against the positioning groove wall 12, ensuring the stable position of the angle block 100 on the display unit 10. At the same time, the first fastening mechanism 200 is not exposed and does not occupy the external space of the display unit 10.

[0059] Specifically, the display unit 10 includes a display cabinet and a display module. The display module is installed in the display cabinet. The display cabinet has a mounting groove 11. Multiple display cabinets are spliced with each other to realize the splicing of multiple display units 10.

[0060] In some embodiments, combined with Figure 5 and Figure 6 , the first included angle formed between the first mounting positioning surface 110 and the splicing positioning surface 130 is -1° to 1°. In this way, when the angle block 100 is positioned and installed on the first display unit 10 using the first mounting positioning surface 110 and abuts against the second display unit 10 using the splicing positioning surface 130, the splicing angle between the two display units 10 is -1° to 1°, realizing straight screen splicing, small-angle concave or small-angle convex, and meeting the morphological requirements of presenting a basic plane between the two display units 10.

[0061] Optionally, the first included angle is -1°, -0.5°, 0°, 0.5° or 1°, which is not limited here.

[0062] In some embodiments, combined with Figure 7 and Figure 8The second included angle formed between the second installation positioning surface 120 and the splicing positioning surface 130 is 1.2° to 7.5°. That is, the splicing angle between the two display units 10 is 1.2° to 7.5°, meeting the morphological requirement of the two display units 10 presenting a convex shape. Moreover, the splicing angle is not greater than 7.5°, avoiding the appearance of splicing gaps and improving the splicing effect.

[0063] Optionally, the second included angle is 1.2°, 2°, 2.5°, 5° or 7.5°, which is not limited herein.

[0064] In some embodiments, in combination with Figure 3 , Figure 9 and Figure 10 , the angle block 100 has a third installation positioning surface 140 facing the first direction X. A third included angle is formed between the third installation positioning surface 140 and the splicing positioning surface 130, and the third included angle is different from the first included angle and the second included angle respectively. The addition of the third installation positioning surface 140 to the angle block 100 increases the diversity of the splicing angle and can meet the more diverse splicing requirements of the display screen, which is particularly important in display screens that need to form complex curved surfaces or special angle layouts.

[0065] In one of the embodiments, the third included angle is -7.5° to -1.2°. That is, the splicing angle between the two display units 10 can be -7.5° to -1.2°, meeting the morphological requirement of the two display units 10 presenting a concave shape. Moreover, the absolute value of the splicing angle is not greater than 7.5°, reducing the splicing gap and improving the splicing effect.

[0066] Optionally, the third included angle is -1.2°, -2°, -2.5°, -5° or -7.5°, which is not limited herein.

[0067] In some embodiments, in combination with Figure 1 and Figure 2 , any one of the first installation positioning surface 110, the second installation positioning surface 120 and the splicing positioning surface 130 can be a plane or a curved surface, which is not limited herein. Generally, the first installation positioning surface 110 and the second installation positioning surface 120 are both planes or arc surfaces with the same curvature, so as to be positioned and installed on the same positioning surface (such as the positioning groove wall 12) of the display unit 10. Of course, the first installation positioning surface 110 and the second installation positioning surface 120 can also have different shapes, and the display unit 10 is provided with positioning surfaces adapted to the first installation positioning surface 110 and the second installation positioning surface 120 respectively.

[0068] Optionally, the first mounting positioning surface 110, the second mounting positioning surface 120, and the splicing positioning surface 130 are all flat surfaces. On the one hand, this reduces the difficulty of processing and manufacturing. On the other hand, it facilitates quick splicing and positioning without considering the alignment of curved surfaces, and the flat surface limit abuts stably. Optionally, the third mounting positioning surface 140 is also a flat surface.

[0069] In this embodiment, the first mounting positioning surface 110, the second mounting positioning surface 120, and the splicing positioning surface 130 can be located on any side of the angle block 100 in the first direction X, which is not limited herein. For example, the first mounting positioning surface 110, the second mounting positioning surface 120, and the splicing positioning surface 130 are all located on the same side of the angle block 100. Another example is that two of the first mounting positioning surface 110, the second mounting positioning surface 120, and the splicing positioning surface 130 are located on one side of the angle block 100, and the other is located on the other side of the angle block 100, making full use of the surface space distribution of the angle block 100. On the one hand, it is beneficial for each positioning surface to be designed with a large area to improve the limit strength. On the other hand, they are staggered in the surface space, which is beneficial for each positioning surface to separately achieve the positioning function without interference.

[0070] Optionally, the third mounting positioning surface 140 can also be located on any side of the angle block 100 in the first direction X.

[0071] In some embodiments, in combination with Figure 1 and Figure 2 , the splicing positioning surface 130 includes a first splicing reference surface 131 and a second splicing reference surface 132, and the first splicing reference surface 131 and the second splicing reference surface are respectively located on both sides of the angle block 100 in the first direction X. In this way, splicing positioning surfaces 130 are provided on both sides of the angle block 100, and during on-site splicing, the splicing reference surface on one side can be flexibly selected for splicing and positioning without complex adjustment and calculation, improving the splicing efficiency and also improving the layout flexibility of the first mounting positioning surface 110 and the second mounting positioning surface 120.

[0072] Optionally, the first mounting positioning surface 110 and the second mounting positioning surface 120 can also be arbitrarily arranged on one or both sides of the angle block 100, which is not limited herein, so as to make full use of the surface space of the angle block 100. When the first mounting positioning surface 110 and the second mounting positioning surface 120 are located on different sides of the angle block 100 respectively, they are arranged staggeredly, do not interfere with each other's positioning and matching, and are conducive to maximizing the area design. When the first mounting positioning surface 110 and the second mounting positioning surface 120 are simultaneously distributed on both sides of the angle block 100, different mounting angles of the display unit 10 can be achieved on either side of the angle block 100, improving the flexibility and efficiency of on-site assembly. When the first mounting positioning surface 110 and the second mounting positioning surface 120 are simultaneously integrated on one side of the angle block 100, different mounting angles can be achieved without adjusting the mounting direction of the angle block 100, reducing the processing difficulty of the angle block 100, and the other side of the angle block 100 can be separately used for connection and cooperation with the first fastening mechanism 200, facilitating on-site splicing.

[0073] In one embodiment, any one of the first splicing reference surface 131 and the second splicing reference surface 132 forms a first included angle with the first mounting positioning surface 110, that is, the first splicing reference surface 131 and the second splicing reference surface 132 are arranged in parallel. The first mounting positioning surface 110 can cooperate with any one of the splicing reference surfaces, improving the splicing flexibility.

[0074] In one embodiment, any one of the first splicing reference surface 131 and the second splicing reference surface 132 forms a second included angle with the second mounting positioning surface 120. The second mounting positioning surface 120 can cooperate with any one of the splicing reference surfaces, improving the splicing flexibility.

[0075] In one embodiment, any one of the first splicing reference surface 131 and the second splicing reference surface 132 forms a third included angle with the third mounting positioning surface 140. The third mounting positioning surface 140 can cooperate with any one of the splicing reference surfaces, improving the splicing flexibility.

[0076] In one embodiment, combined with Figure 1 , the first mounting positioning surface 110 and the first splicing reference surface 131 are located on the same side of the angle block 100 in the first direction X. The first mounting positioning surface 110 and the first splicing reference surface 131 form a first included angle. Since the first mounting positioning surface 110 and the first splicing reference surface 131 are closely adjacent and on the same side, their relative positional relationship is very stable, ensuring the high reliability of the manufacturing accuracy and measurement accuracy of the first included angle. Moreover, it is convenient for on-site assembly personnel to simultaneously perform splicing and positioning of the angle block 100 with the first display unit 10 and the second display unit 10 on the same side.

[0077] In one embodiment, the second installation positioning surface 120 and the second splicing reference surface 132 are located on the same side of the angle block 100 in the first direction X, and the second installation positioning surface 120 and the second splicing reference surface 132 form a second angle. Since the second installation positioning surface 120 and the second splicing reference surface 132 are closely adjacent and located on the same side, the relative positional relationship between them is very stable, ensuring that the manufacturing accuracy and measurement accuracy of the second angle are highly reliable, and it is convenient for on-site assemblers to simultaneously perform splicing positioning of the angle block 100 with the first display unit 10 and the second display unit 10 on the same side.

[0078] In one embodiment, the third installation positioning surface 140 and the second splicing reference surface 132 are located on the same side of the angle block 100 in the first direction X, and the third installation positioning surface 140 and the second splicing reference surface 132 form a third angle. Since the third installation positioning surface 140 and the second splicing reference surface 132 are closely adjacent and located on the same side, the relative positional relationship between them is very stable, ensuring that the manufacturing accuracy and measurement accuracy of the third angle are highly reliable, and it is convenient for on-site assemblers to simultaneously perform splicing positioning of the angle block 100 with the first display unit 10 and the second display unit 10 on the same side.

[0079] Optionally, the second installation positioning surface 120 and the third installation positioning surface 140 are set up vertically, making full use of the height space on the same side of the angle block 100 to set the two installation positioning surfaces, which will not increase the width of the angle block 100. The angle block 100 is positioned and matched with the first display unit 10 through the positioning surfaces at different heights, and the size of the first display unit 10 remains unchanged without the need for additional corresponding modification designs.

[0080] In some embodiments, in combination Figure 5 and Figure 6 The angle block 100 includes a block body 150 and a mounting rib 160. The mounting rib 160 is connected to the side of the block body 150 in the second direction Y. The end surface of the block body 150 in the first direction X forms a splicing positioning surface 130. The mounting rib 160 has a first mounting positioning surface 110 and a second mounting positioning surface 120. The block body 150 and the mounting rib 160 are respectively used for positioning and matching with the first display unit 10 and the second display unit 10, with separate functions and no interference.

[0081] Optionally, mounting ribs 160 are provided on both sides of the block body 150 to improve the stability of positioning force.

[0082] In some embodiments, in combination Figure 1 and Figure 2The angle block 100 has a mounting hole 170 that passes through the angle block 100 along the first direction X. The inner wall of the mounting hole 170 is provided with first limiting steps 171 and a locking plate 172 that are spaced apart along the first direction X. The locking plate 172 has a locking hole 173. The first limiting step 171 can facilitate the angle block 100 to withstand the pressing force, fix the angle block 100 on the first display unit 10, and enhance the stability of the installation. The locking hole 173 can facilitate the locking connection between the angle block 100 and the second display unit 10, and improve the reliability of the splicing.

[0083] Optionally, the block body 150 has the mounting hole 170. As the main structure of the angle block 100, the block body 150 bears the pressing force of the fixed connection with the first display unit 10 and the locking force of the fixed connection with the second display unit 10, thereby improving the splicing strength and splicing stability between the two display units 10.

[0084] In one embodiment, in combination Figure 1 and Figure 2 The locking hole 173 has a first aperture φ1 in the first radial direction, and the locking hole 173 has a second aperture φ2 in the second radial direction, and the first aperture φ1 and the second aperture φ2 are different.

[0085] For example, the first aperture φ1 is larger than the second aperture φ2, and the end size of the second tightening mechanism 30 installed on the second display unit 10 is between the first aperture φ1 and the second aperture φ2. The end of the second tightening mechanism 30 passes through the locking hole 173 along the first radial direction and then rotates to the second radial direction without being able to escape from the locking hole 173, thereby achieving locking of the second tightening mechanism 30 and the angle block 100 without the need for an additional locking device or a complex mechanical structure, and locking or unlocking can be achieved through a rotation operation, with high assembly efficiency.

[0086] In one embodiment, in combination Figure 1 and Figure 2 A second limiting step 174 is convexly formed on the inner wall of the mounting hole 170, and the first limiting step 171 and the second limiting step 174 are distributed on both sides of the locking plate 172. The angle block 100 can withstand the pressing force fixedly connected to the first display unit 10 on either side, thereby improving the installation flexibility of the angle block 100 and making full use of the space on both sides of the angle block 100 to set a first mounting positioning surface 110, a second mounting positioning surface 120 and other multiple mounting positioning surfaces.

[0087] In one embodiment, in combination Figure 1 and Figure 2, the first limiting step 171 and the first mounting and positioning surface 110 are located on opposite sides of the angle block 100 in the first direction X. When the first mounting and positioning surface 110 abuts against the first display unit 10, the first limiting step 171 bears the pressing force to tightly abut the first mounting and positioning surface 110 against the first display unit 10, improving the stability and reliability of the positioning fit, and at the same time realizing the fixed installation of the angle block 100 on the first display unit 10.

[0088] In one embodiment, in combination with Figure 1 and Figure 2 , the second limiting step 174 and the second mounting and positioning surface 120 are located on opposite sides of the angle block 100 in the first direction X. When the second mounting and positioning surface 120 abuts against the first display unit 10, the second limiting step 174 bears the pressing force to tightly abut the second mounting and positioning surface 120 against the first display unit 10, improving the stability and reliability of the positioning fit, and at the same time realizing the fixed installation of the angle block 100 on the first display unit 10.

[0089] In one embodiment, in combination with Figure 1 and Figure 2 , the second mounting and positioning surface 120 and the third mounting and positioning surface 140 are located on the same side of the angle block 100, and the second limiting step 174 and the third mounting and positioning surface 140 are located on opposite sides of the angle block 100 in the first direction X. The second limiting step 174 is used to bear the pressing force to tightly abut the third mounting and positioning surface 140 against the first display unit 10, improving the stability and reliability of the positioning fit, and at the same time realizing the fixed installation of the angle block 100 on the first display unit 10.

[0090] In some embodiments, in combination with Figures 1 to 3 , the mounting hole 170 forms a first arc surface 175 around the hole wall of the first limiting step 171. The first arc surface 175 is used to be adapted to the end of the first fastening mechanism 200. When the first mounting and positioning surface 110 is used for positioning and installing on the first display unit 10, the first fastening mechanism 200 presses on the first limiting step 171, and its radial and circumferential directions are limited by the first arc surface 175, ensuring the stability and reliability of the direction and position of the pressing force.

[0091] In some embodiments, in combination with Figures 1 to 3 , the mounting hole 170 forms a second arc surface 176 around the hole wall of the second limiting step 174. The second arc surface 176 is used to be adapted to the end of the first fastening mechanism 200. When the second mounting and positioning surface 120 is used for positioning and installing on the first display unit 10, the first fastening mechanism 200 presses on the second limiting step 174, and its radial and circumferential directions are limited by the second arc surface 176, ensuring the stability and reliability of the direction and position of the pressing force.

[0092] In some embodiments, in combination with Figures 1 to 3 , the mounting hole 170 forms a third arc surface 177 around the hole wall of the second limiting step 174. The third arc surface 177 is adapted to the end of the first fastening mechanism 200. When the third mounting and positioning surface 140 is used for positioning and mounting on the first display unit 10, the first fastening mechanism 200 presses against the second limiting step 174, and its radial and circumferential directions are limited by the third arc surface 177, ensuring the stability and reliability of the direction and position of the pressing force.

[0093] Specifically, when the second mounting and positioning surface 120 is located below the third mounting and positioning surface 140, the second arc surface 176 is located below the third arc surface 177. When the angle block 100 is positioned and mounted on the first display unit 10 through the second mounting and positioning surface 120, the first fastening mechanism 200 abuts against the angle block 100 and is limited by the second arc surface 176. When the angle block 100 is inverted and positioned and mounted on the first display unit 10 through the third mounting and positioning surface 140, at this time, the first fastening mechanism 200 does not need to be inverted, keeps the height unchanged, still abuts against the angle block 100, and is exactly limited by the third arc surface 177. In this way, the mounting height of the first fastening mechanism 200 on the display unit 10 does not need to be adjusted. The adjustment of the mounting angle of the angle block 100 will not affect the mounting changes of other components, simplifying the assembly operation of the display unit 10.

[0094] Specifically, the first arc surface 175 and the second arc surface 176 have the same diameter and the same central angle, so the limiting areas of the end of the first fastening mechanism 200 on the first arc surface 175 and the second arc surface 176 are the same, ensuring that the state of the first fastening mechanism 200 is basically unchanged at different splicing angles, and simplifying the assembly operation of the display unit 10.

[0095] Optionally, the first arc surface 175, the second arc surface 176 and the third arc surface 177 have the same diameter and the same central angle. Since the second arc surface 176 and the third arc surface 177 are located on the same side of the angle block 100 and are arranged one above the other, the contour of one side of the mounting hole 170 surrounded by the two is in a gourd shape.

Optionally, the pressing block 220 abuts against the first limiting step 171 or the second limiting step 174. The diameter of the pressing block 220 is the same as the diameter of the first arc surface 175. Optionally, the fastening rod 210 is threadedly connected to the display unit 10 to achieve stable feeding. For example, the display unit 10 has a first assembly hole, and the fastening rod 210 is threadedly passed through the first assembly hole. Optionally, the first fastening mechanism 200 further includes a first fastener 250. The first fastener 250 passes through the pressing block 220 and the fastening rod 210 to fixedly install the pressing block 220 on the fastening rod 210.

[0100] Specifically, the first fastening mechanism 200 further includes a first handle 230. The first handle 230 is sleeved on one end of the fastening rod 210 away from the pressing block 220. When the first handle 230 rotates, it drives the fastening rod 210 to rotate, and then the fastening rod 210 feeds threadedly on the display unit 10. Optionally, the first fastening mechanism 200 further includes a first elastic member 240 and a second fastener 260. The second fastener 260 is installed at one end of the fastening rod 210 away from the pressing block 220. The first elastic member 240 is compressively arranged between the second fastener 260 and the first handle 230 to press the first handle 230 against the fastening rod 210 to ensure stable socketing and cooperation between the first handle 230 and the fastening rod 210 without loosening.

[0102] In combination with Figure 4 、 Figure 13 and Figure 14, the present application provides a display screen. The display screen includes two adjacent display units 10, a second fastening mechanism 30, and any one of the angular splicing structures 20 in the second embodiment. The angle block 100 is limited and abutted against the first display unit 10 through either the first mounting and positioning surface 110 or the second mounting and positioning surface 120. The splicing and positioning surface 130 of the angle block 100 abuts against the second display unit 10. Thus, the splicing angle between the two display units 10 is the first included angle between the first mounting and positioning surface 110 and the splicing and positioning surface 130, or the included angle between the second mounting and positioning surface 120 and the splicing and positioning surface 130, realizing adjustable splicing angle and ensuring stable and reliable abutment.

[0103] The first fastening mechanism 200 is installed on the first display unit 10. The first fastening mechanism 200 fixedly installs the angle block 100 on the first display unit 10. The second fastening mechanism 30 is installed on the second display unit 10. The second fastening mechanism 30 is fixedly connected to the angle block 100. The first fastening mechanism 200 and the second fastening mechanism 30 are respectively fixedly connected to the angle block 100, enhancing the splicing strength between the two display units 10.

[0104] In some embodiments, combined with Figure 13 and Figure 14 , the second fastening mechanism 30 includes a locking rod 31 and a second handle 313. The second handle 313 is connected to one end of the locking rod 31. The other end of the locking rod 31 is used for locking connection with the angle block 100 located on the other display unit 10.

[0105] Specifically, the second handle 313 sleeves the locking rod 31. The second handle 313 drives the locking rod 31 to rotate.
