[0002] At present, with the rapid development of digital display technology, LED display screen has been widely used in many fields such as advertisement display, information release, stage layout, sports events and the like due to its high brightness, low energy consumption, long service life and strong customizability. When the LED display screen is installed on the support, the fixed support connecting block is often used for auxiliary fixing to install the LED screen more firmly on the support.

[0003] However, the traditional LED screen fixed support design can only adapt to one specification or type of LED screen, which means that when the screw hole size on the LED screen backboard is different, such as M6, M8 or M10, different LED screen fixed supports need to be used to match these different specifications, resulting in that the user has to purchase multiple different specifications of LED screen fixed supports when facing different types or brands of LED screens, or the fixed support is fixed with a connecting block, which is matched and installed with the screw hole on the LED screen backboard, but when the LED screen needs to be replaced, if the screw hole types used by the new and old LED screens are inconsistent, the original connecting block may need to be reassembled to adapt to the new screen, which not only increases the workload, but also reduces the work efficiency. In addition, for manufacturers, in order to meet the needs of various specifications on the market, multiple types of connecting blocks must be produced, which undoubtedly increases the complexity and cost of production, and also causes resource waste.

Figure 1 and FIG. 2, the connecting block assembly 2 comprises a connecting block main body 21 and a connecting block accessory 22. Figure 2As shown, an LED screen fixing support comprises a plurality of support assemblies 1 and a plurality of connecting block assemblies 2 arranged in a first direction, i.e., a vertical direction, on the support assemblies 1, the connecting block assemblies 2 serving as connecting points to fix a plurality of LED sub-screens 3 to the support assemblies 1, the plurality of support assemblies 1 can be connected and limited in position in a second direction, i.e., a horizontal direction, by a support assembly fixing frame 4, each LED sub-screen 3 is connected to the support assembly 1 by at least one connecting block assembly 2, and the plurality of LED sub-screens 3 can be assembled into an entire LED display large screen in the first direction and the second direction through the connecting block assemblies 2, further, the number of the support assemblies 1 and the length of the support assembly fixing frame 4 can be flexibly increased or reduced as needed, so that the size of the entire LED display large screen can be adjusted according to requirements.

[0044] Specifically, as shown in the accompanying drawings, Figure 4 to the accompanying drawings, Figure 7 As shown, the connecting block assembly 2 comprises a connecting block main body 21 and a connecting block accessory 22, the connecting block main body 21 is provided with a first embedded interface 211 for accommodating a fastener or the connecting block accessory 22, which can be applied to a fastener with a larger diameter, the connecting block accessory 22 is provided with a second embedded interface 221 for accommodating a fastener, which can be applied to a fastener with a smaller diameter, and the connecting block accessory 22 can be detachably connected to the first embedded interface 211 to selectively determine whether to be installed on the connecting block main body 21.

[0045] The LED screen fixing support of the utility model firstly positions a plurality of LED sub-screens 3 to be assembled into an entire LED display large screen through a plurality of support assemblies 1 and connecting block assemblies 2, and then the connecting block accessory 22 is detachably connected to the first embedded interface 211 of the connecting block main body 21, so that users can flexibly select whether to directly use the connecting block main body or to increase the use of the connecting block accessory according to the size requirements of the fastener mounting hole of the LED sub-screen 3, the LED sub-screen 3 of different specifications can be replaced without disassembling the entire connecting block assembly, the LED screen fixing support does not need to be replaced or disassembled on a large scale, the installation time and complexity are greatly reduced, the installation and subsequent maintenance processes are simplified, and the installation requirements of most LED sub-screens on the market can be adapted.

[0046] In some embodiments of the present application, as shown in the accompanying drawings, Figure 4As shown, the first embedded interface 211 includes a first receiving groove 2111 and a clamping boss 2112 located in the first receiving groove 2111, the clamping boss 2112 has a first planar area 2113 which is a flat surface capable of abutting against the abutting surface at the bottom of the connecting block accessory 22 to ensure close contact and uniform distribution of force, or used to fit the head of a fastener, the clamping boss 2112 also has a first mounting hole 2114 which penetrates the clamping boss 2112, the first mounting hole 2114 is used to provide sufficient space for the body part of the fastener (such as a bolt or screw), the starting end of the first mounting hole 2114 is located on the first planar area 2113, and the outer edge of the first planar area 2113 is connected with the inner wall of the first receiving groove 2111.

[0047] Specifically, when the LED sub-screen 3 with a fastener mounting hole of larger size needs to be connected with the connecting block assembly 2, first, the body part of the fastener is screwed or hammered into the first receiving groove 2111, at this time the body part of the fastener passes through the clamping boss 2112 and is aligned with the corresponding mounting point, i.e. the fastener mounting hole on the LED sub-screen 3, then the tool is used to continue operating the fastener, so that the head of the fastener abuts against the first planar area 2113, and the end of the body part of the fastener enters the fastener mounting hole of the LED sub-screen 3, so that the LED sub-screen 3 is fixed to the support assembly 1 through the connecting block assembly 2. When the LED sub-screen 3 with a fastener mounting hole of smaller size needs to be connected with the connecting block assembly 2, first, the connecting block accessory 22 is installed on the first embedded interface 211. At this time, the abutting surface at the bottom of the connecting block accessory 22 will be in contact with the first planar area 2113. Then, the body part of the fastener is screwed or hammered into the connecting block accessory 22, at this time the body part of the fastener passes through the connecting block accessory 22 and is aligned with the corresponding mounting point, i.e. the fastener mounting hole on the LED sub-screen 3, then the tool is used to continue operating the fastener, so that the end of the body part of the fastener enters the fastener mounting hole of the LED sub-screen 3, so that the LED sub-screen 3 is fixed to the support assembly 1 through the connecting block assembly 2.

[0048] In some embodiments of the present application, as shown in the accompanying drawings Figure 5As shown, the second embedded interface 221 comprises a second accommodating groove 2211 and a clamping portion 2212 located in the second accommodating groove 2211, the clamping portion 2212 has a second planar area 2213 and a second mounting hole 2214 penetrating the clamping portion 2212, the second planar area 2213 is a flat surface capable of closely contacting the head of the fastener to ensure uniform distribution of force, the starting end of the second mounting hole 2214 is located on the second planar area 2213, the outer edge of the second planar area 2213 is connected with the inner wall of the second accommodating groove 2211, and the second planar area 2213 is used to abut against the head of the fastener. It is worth noting that the inner diameter of the second mounting hole 2214 is smaller than that of the first mounting hole 2114, so as to be distinguished from the first mounting hole 2114 to adapt to the needs of fasteners of different specifications. Therefore, specifically, when the LED sub-screen 3 with a fastener mounting hole of a smaller size needs to be connected with the connecting block assembly 2, the connecting block fitting 22 is first installed on the first embedded interface 211. At this time, the abutting surface at the bottom of the connecting block fitting 22 abuts against the first planar area 2113. Then, the body portion of the fastener is screwed or nailed into the second accommodating groove 2211, at this time the body portion of the fastener penetrates the clamping portion 2212 and is aligned with the corresponding mounting point, that is, the fastener mounting hole on the LED sub-screen 3, and then the tool is used to continue to operate the fastener, so that the end of the body portion of the fastener enters the fastener mounting hole of the LED sub-screen 3, and the LED sub-screen 3 is fixed to the support assembly 1 through the connecting block assembly 2.

[0049] In some embodiments of the present application, as shown in the accompanying drawings Figure 6 and the accompanying drawings Figure 8 As shown, the second mounting hole 2214 extends in the direction of the abutting surface to form a centrally penetrating protrusion 2215, the inner wall of the protrusion 2215 abuts against the outer wall of the fastener to provide additional support and guidance, and the outer wall of the protrusion 2215 abuts against the inner wall of the first mounting hole 2114, which not only enhances the overall structural strength of the connecting block fitting 22, but also provides an effective force application point for the disassembly tool. When it is necessary to disassemble the connecting block fitting 22, the tip of the disassembly tool can be directly used to apply force to the outer wall of the protrusion 2215 from the contact surface between the connecting block body 21 and the LED sub-screen 3, so as to push the connecting block fitting 22 out of the first embedded interface 211. It is worth noting that the extension length of the protrusion 2215 does not exceed the axial length of the first mounting hole 2114, that is, the protrusion is prevented from protruding from the contact surface between the connecting block body 21 and the LED sub-screen 3, so as to avoid uneven contact between the connecting block body 21 and the LED sub-screen 3, and thus avoid excessive local contact pressure during the installation of the fastener, thereby damaging the LED sub-screen.

[0050] In some embodiments of the present application, as shown in the accompanying drawings Figure 2 to the accompanying drawings Figure 8As shown, the connecting block body 21 is provided with a clamping groove 212, specifically a groove or an opening, and the support assembly 1 comprises a clamping strip 11, which is a protruding part provided on the support assembly 1 and has a shape matched with the clamping groove 212. Preferably, the size of the clamping strip 11 is slightly smaller than that of the clamping groove 212, so as to facilitate the clamping of the connecting block body 21 and the clamping strip 11 through the clamping groove 212, and the first embedded interface 211 corresponds to the fastener mounting hole of the LED sub-screen 3. According to the position of the fastener mounting hole of the LED sub-screen with different sizes and shapes, the position of the connecting block body 21 is adjusted to clamp the clamping groove 212 and the clamping strip 11. After adjustment, due to the fact that the initial clamping and positioning connection mode may not be able to withstand the gravity of the LED sub-screen 3 in long-term use, in order to ensure the stability in long-term use, the clamping groove 212 and the clamping strip 11 are fixedly connected for secondary fixation.

[0051] In some embodiments of the present application, as shown in FIG. 1, the support assembly 1 is provided with a plurality of connecting block bodies 21, and the connecting block bodies 21 are arranged in a staggered manner. Figure 3 As shown, the support assembly 1 is provided with a hollow area 12 through the side wall, and the clamping strip 11 protrudes from the hollow area 12. On the one hand, when the connecting block body 21 is fixedly connected with the support assembly 1, the part of the connecting block body 21 located in the hollow area 12 is clamped and fixedly connected with the clamping strip 11, and the remaining part of the connecting block body 21 including the first embedded interface 211 is exposed to the support assembly 1, which provides better visibility and operation space, facilitating the installation or disassembly of the fastener and the connecting block accessory 22, and improving the replacement efficiency.

[0052] In some embodiments of the present application, the connecting block body 21 can slide relative to the clamping strip 11 through the clamping groove 212, so that the connecting block body 21 has a position adjustment degree of freedom. During installation, first, the clamping groove 212 on the connecting block body 21 is aligned with the clamping strip 11 on the support assembly 1, and then the clamping strip 11 is pushed along the setting direction to slide into the clamping groove 212. After sliding to the position corresponding to the fastener mounting hole of the LED sub-screen 3, the clamping groove 212 is fixedly connected with the clamping strip 11 through gluing, welding or fasteners, which effectively prevents the connecting block body 21 from accidentally sliding or shifting due to the gravity of the LED sub-screen during use.

[0053] In some embodiments of the present application, in order to facilitate transportation and assembly, as shown in FIG. 1, the support assembly 1 is provided with a plurality of connecting block bodies 21, and the connecting block bodies 21 are arranged in a staggered manner. Figure 1 to FIG. 1, Figure 3As shown, a set of support components 1 is spliced ​​together from at least two support rods 13, which can ensure the balance of the entire support structure and avoid structural deformation or damage of support components 1 due to uneven force. The splice 131 is located at the center line (the dotted line position in the figure) of the corresponding LED sub-screen 3. At the splice, two adjacent support rods 13 are symmetrically provided with connecting block components 2, and the symmetrically provided connecting block components 2 are connected to the same LED sub-screen 3 corresponding to the splice 131. This makes the symmetrically provided connecting block components 2 and the splice 131 form a stable triangular structure on the same LED sub-screen 3, which enhances the overall stability of the support components 1.

[0054] In some embodiments of the present invention, as shown in the appendix Figure 4 and attached Figure 5 As shown, the first receiving groove 2111 and the second receiving groove 2211 are hexagonal in shape. Compared with the circular interface, they can effectively prevent the fastener from rotating and can be adapted to various types of fasteners. For example, most screws or nuts commonly used on the market are hexagonal. The hexagonal embedded interface can be well matched with these standard screws and nuts, making it convenient for users to use existing fasteners of various specifications without the need to customize fasteners of special shapes.

[0055] In some embodiments of the present invention, the fasteners adapted to the first embedded interface 211 are M8 screws, M8 nuts, M10 screws, and M10 nuts, specifically, as shown in the attached diagram. Figure 9 As shown, this is a connector block assembly with M10 screws installed in one embodiment. In this case, only the connector block body 21 is needed to adapt the M10 screws. The M10 screws can be inserted from one side of the connector block body 21 or from the side of the rear LED screen during installation; as shown in the attached diagram. Figure 10 As shown, this is a connector block assembly with M8 screws installed in one embodiment. In this case, only the connector block body 21 is needed to adapt the M8 screws. The M8 screws can be inserted from one side of the connector block body 21 or from the side of the rear LED screen during installation; as shown in the attached diagram. Figure 11 As shown, this is a connector block assembly with an M8 nut installed in one embodiment. In this case, only the connector block body 21 is needed to adapt the M8 nut. The M8 nut needs to be embedded into one side of the connector block body 21 during installation. Further, the fasteners adapted to the second embedded interface 221 are M6 screws and M6 nuts, specifically as shown in the attached diagram. Figure 12 As shown, this is a connecting block assembly with M6 screws installed in one embodiment. First, the connecting block accessory 22 and the connecting block body 21 need to be assembled into the connecting block assembly 2. The connecting block assembly 2 is then used to adapt the M6 ​​screws. The M6 ​​screws can be inserted from one side of the connecting block assembly 2 or from the side of the rear LED screen during installation. (See attached diagram.) Figure 13As shown, it is a connecting block assembly provided with an M6 nut in an embodiment, and similarly, the connecting block fitting 22 needs to be assembled with the connecting block body 21 into the connecting block assembly 2 at this time, and the M6 nut is fitted by using the connecting block assembly 2, and the M6 nut needs to be embedded and installed on one side of the connecting block assembly 2 during installation.

[0056] The above embodiment is only a preferred embodiment of the present application, and cannot be used to limit the scope of protection of the present application. Any non-essential changes and replacements made by those skilled in the art on the basis of the present application shall fall within the scope of protection of the present application.
