[0002] In related technologies, suspended LED display devices use suspension beams to mount the LED display screen onto an external mounting base.

[0003] The hanging beam and the LED display screen are usually connected by screws. When the LED display screen needs to be removed from the hanging beam for maintenance, the screws are easy to fall off or be lost, which will affect the subsequent operation of connecting the hanging beam and the LED display screen. Utility Model Content

[0004] The main purpose of this utility model is to provide a hanging beam structure and an LED display device having the same, so as to solve the problem that screws are easy to fall off or be lost when maintaining LED displays in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a suspension beam structure is provided for mounting an LED display screen. The suspension beam structure includes: a crossbeam; and a non-detachable screw assembly, which includes a mounting base, a connecting screw, and a resetting member. The mounting base is installed inside the crossbeam, and both the connecting screw and the resetting member are mounted on the mounting base. The connecting screw has a connecting position and a retracted position. When the connecting screw is in the connecting position, it extends downwards out of the crossbeam; when the connecting screw is in the retracted position, it retracts into the interior of the crossbeam. The resetting member applies a resetting force to the connecting screw so that it remains in the retracted position.

[0006] Furthermore, the crossbeam has a cavity extending through it in the transverse direction, and the non-removable screw assembly is disposed within the cavity.

[0007] Furthermore, a first operating opening is provided on the top wall of the crossbeam, which is located above the captive screw assembly and communicates with the cavity.

[0008] Furthermore, the suspension beam structure also includes lifting rings set on the top wall of the beam.

[0009] Furthermore, a second operating opening is provided on the bottom wall of the crossbeam, which is located below the lifting ring and communicates with the cavity.

[0010] Furthermore, the connecting screw includes a first rod segment and a second rod segment located below the first rod segment. The lateral dimension of the second rod segment is larger than that of the first rod segment. A connecting thread is provided on the outer surface of the second rod segment. The mounting base is provided with a through hole for the connecting screw to pass through. The through hole includes a first hole segment and a second hole segment located below the first hole segment. The lateral dimension of the second hole segment is larger than that of the first hole segment. A stop step surface is formed between the first hole segment and the second hole segment. The first rod segment slides in fit with the first hole segment. When the connecting screw is in the retracted position, the upper surface of the second rod segment stops in fit with the stop step surface.

[0011] Furthermore, the connecting screw includes a rod body and a cap body located at the upper end of the rod body. The reset element is a spring sleeved on the rod body, with both ends of the spring engaging with the mounting base and the cap body respectively.

[0012] Furthermore, the mounting base is provided with a through hole for the connecting screw to pass through, the through hole including a receiving hole section, and the spring is located within the receiving hole section.

[0013] Furthermore, positioning holes are provided on the bottom wall of the crossbeam.

[0014] According to another aspect of the present invention, an LED display device is provided, including a suspension beam structure and an LED display screen connected below the suspension beam structure, wherein the suspension beam structure is the aforementioned suspension beam structure.

[0015] The technical solution of this utility model includes a beam structure comprising a crossbeam and a captive screw assembly mounted on the crossbeam. The captive screw assembly is used to connect to the LED display screen. When assembling the beam structure and the LED display screen, the captive screw assembly remains mounted on the crossbeam and will not separate from it. Therefore, the captive screw assembly is less likely to fall off or be lost, facilitating the assembly and disassembly of the beam structure and the LED display screen. Furthermore, when the captive screw assembly is not connected to the LED display screen, the connecting screw is held in its retracted position by a reset component, preventing the end of the connecting screw from colliding with the LED beads on the LED display screen and damaging them. When the captive screw assembly is connected to the LED display screen, the connecting screw is pushed to the connection position and threadedly connected to the LED display screen, thus fixing the LED display screen to the beam structure. Therefore, the technical solution of this application effectively solves the problem of screws easily falling off or being lost during the maintenance of LED displays in related technologies.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present utility model or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0034] like Figures 1 to 6 As shown, this application provides a suspension beam structure for mounting an LED display screen 1. An embodiment of the suspension beam structure of this application includes a crossbeam 10 and a non-detachable screw assembly 20. The non-detachable screw assembly 20 includes a mounting base 21, a connecting screw 22, and a resetting member 23. The mounting base 21 is installed inside the crossbeam 10. The connecting screw 22 and the resetting member 23 are both installed on the mounting base 21. The connecting screw 22 has a connecting position and a retracted position. When the connecting screw 22 is in the connecting position, the connecting screw 22 extends downward from the crossbeam 10. When the connecting screw 22 is in the retracted position, the connecting screw 22 retracts into the interior of the crossbeam 10. The resetting member 23 applies a resetting force to the connecting screw 22 so that the connecting screw 22 can be held in the retracted position.

[0035] Applying the technical solution of this embodiment, the suspension beam structure includes a crossbeam 10 and a captive screw assembly 20 disposed on the crossbeam 10. The captive screw assembly 20 is used to connect with the LED display screen 1. When the suspension beam structure and the LED display screen 1 need to be assembled, the captive screw assembly 20 is always installed on the crossbeam 10 and will not separate from the crossbeam 10. Therefore, the captive screw assembly 20 is not easy to fall off or be lost, which facilitates the assembly and disassembly of the suspension beam structure and the LED display screen 1. In addition, when the captive screw assembly 20 is not connected to the LED display screen 1, the connecting screw 22 will be held in the storage position and hidden inside the crossbeam 10 under the action of the reset member 23. This can prevent the end of the connecting screw 22 from bumping or scratching the LED beads on the LED display screen 1, thus preventing damage or scratches to the LED beads. When the captive screw assembly 20 is connected to the LED display screen 1, the connecting screw 22 is pushed to the connection position and threadedly connected to the LED display screen 1 to fix the LED display screen 1 to the suspension beam structure. Therefore, the technical solution of this embodiment can effectively solve the problem of screws easily falling off or being lost when maintaining LED displays in related technologies, and has the advantages of simple structure, convenient operation and low cost.

[0036] like Figure 1 , Figure 2 and Figure 4 As shown, the crossbeam 10 has a cavity 11 extending through it in the transverse direction, and the captive screw assembly 20 is disposed within the cavity 11. The cavity 11 within the crossbeam 10 reduces its weight and material usage. Specifically, in this embodiment, the crossbeam 10 is a square tubular structure manufactured by extrusion molding.

[0037] like Figure 1 , Figure 3 and Figure 4 As shown, a first operating opening 12 is provided on the top wall of the crossbeam 10. The first operating opening 12 is located above the captive screw assembly 20 and is connected to the cavity 11. The first operating opening 12 facilitates the operator to insert the operating tool into the cavity 11 to tighten the connecting screw 22, thereby connecting or separating the captive screw assembly 20 from the LED display screen 1.

[0038] like Figures 1 to 3 As shown, the suspension beam structure also includes a lifting ring 30 disposed on the top wall of the crossbeam 10. The lifting ring 30 can be suspended from the external mounting base to realize the installation of the LED display screen 1 in a designated position.

[0039] like Figure 2 and Figure 4 As shown, a second operating opening 13 is provided on the bottom wall of the crossbeam 10. The second operating opening 13 is located below the lifting ring 30 and communicates with the cavity 11. Specifically, the lower end of the lifting ring 30 extends into the crossbeam 10 and is connected to a nut located in the cavity 11 to fix the lifting ring 30 to the crossbeam 10. The second operating opening 13 facilitates the operator's operation of installing the lifting ring 30.

[0040] like Figures 4 to 6As shown, the connecting screw 22 includes a first rod segment 221 and a second rod segment 222 located below the first rod segment 221. The lateral dimension of the second rod segment 222 is larger than that of the first rod segment 221. A connecting thread 223 is provided on the outer surface of the second rod segment 222. The mounting base 21 is provided with a through hole for the connecting screw 22 to pass through. The through hole includes a first hole segment 211 and a second hole segment 212 located below the first hole segment 211. The lateral dimension of the second hole segment 212 is larger than that of the first hole segment 211. A stop step surface 213 is formed between the first hole segment 211 and the second hole segment 212. The first rod segment 221 is in sliding fit with the first hole segment 211. When the connecting screw 22 is in the retracted position, the upper surface of the second rod segment 222 is in stop fit with the stop step surface 213. By stopping the step surface 213 and the upper surface of the second rod segment 222, the second rod segment 222 can be limited within the second hole segment 212, preventing the connecting screw 22 from coming off the mounting base 21 upwards, thus achieving a loose but not detachable effect.

[0041] Specifically, in this embodiment, the inner surface of the first hole segment 211 is provided with an internal thread for engaging with the connecting thread 223. During the assembly of the captive screw assembly 20, the second rod segment 222 is screwed into the first hole segment 211 by engaging with the internal thread on the inner surface of the first hole segment 211. As the screwing progresses, the second rod segment 222 will pass through the first hole segment 211 and completely enter the second hole segment 212. Unless the connecting thread 223 is aligned with the internal thread on the inner surface of the first hole segment 211 and continuously screwed outward, the second rod segment 222 will only engage with the stop step surface 213 and will not enter the first hole segment 211.

[0042] like Figures 4 to 6 As shown, the connecting screw 22 includes a rod portion and a cap portion 224 disposed at the upper end of the rod portion. The reset member 23 is a spring sleeved on the rod portion, with both ends of the spring abutting against the mounting base 21 and the cap portion 224, respectively. The cap portion 224 forms a large-diameter section, and the two ends of the spring abut against the mounting base 21 and the cap portion 224, respectively, so that when the connecting screw 22 is not connected to the LED display screen 1 and is not subjected to other external forces, the connecting screw 22 can be held in the retracted position, preventing the end of the connecting screw 22 from colliding with the LED beads on the LED display screen 1 and damaging the LED beads.

[0043] like Figures 4 to 6As shown, the mounting base 21 has a through hole for the connecting screw 22 to pass through. The through hole includes a receiving section 214, within which the spring is located. The second section 212 guides the movement of the second rod section 222, while the receiving section 214 protects the spring and limits its deformation direction. This ensures that the force exerted by the spring on the cap 224 is vertically upward or only slightly deviated from the vertical direction, preventing the connecting screw 22 from getting stuck and allowing for smoother movement of the connecting screw 22.

[0044] like Figure 2 , Figure 8 and Figure 9 As shown, a positioning hole 41 is provided on the bottom wall of the crossbeam 10. The positioning hole 41 on the crossbeam 10 can be positioned and engaged with the positioning post 42 on the LED display screen 1. When assembling the beam structure and the LED display screen 1, the positioning post 42 is inserted into the positioning hole 41 to achieve initial alignment of the beam structure and the LED display screen 1. Then, the connecting screw 22 is tightened to connect the connecting screw 22 to the LED display screen 1. This makes it easier to align the connecting screw 22 with the connecting hole 103 on the LED display screen 1, and has the advantage of being easy to operate.

[0045] In addition, in this embodiment, the protruding positioning post 42 is set on the LED display screen 1, and the positioning hole 41 is set on the crossbeam 10, which can prevent the protruding structure on the crossbeam 10 from colliding with the LED beads on the LED display screen 1 and damaging the LED beads.

[0046] like Figure 3 , Figure 5 and Figure 6 As shown, the lifting beam structure also includes fasteners 50, which pass through the bottom wall of the crossbeam 10 and the mounting base 21 from bottom to top to fix the mounting base 21 in the cavity 11, thereby fixing the non-removable screw assembly 20 in the cavity 11. Specifically, the fasteners 50 are countersunk screws.

[0047] like Figures 7 to 9 As shown, this application also provides an LED display device. An embodiment of the LED display device includes a suspension beam structure and an LED display screen 1 connected below the suspension beam structure, wherein the suspension beam structure is the aforementioned suspension beam structure. The aforementioned suspension beam structure effectively solves the problem of screws easily falling off or being lost during the maintenance of LED displays in related technologies, and the LED display device with the aforementioned suspension beam structure also has the aforementioned advantages.

[0048] like Figure 8 and Figure 9As shown, the LED display screen 1 includes a housing 102 and a screen 101 disposed on the front side of the housing 102. The housing 102 is used to house the power supply, control board and other structures, and the screen 101 is used to display a specified image under the control of the control board.

[0049] like Figure 9 As shown, the positioning pin 42 is provided on the housing 102. The housing 102 is also provided with a connecting hole 103, and the inner surface of the connecting hole 103 is provided with an internal thread, so that the end of the connecting screw 22 can be connected to the housing 102 through the engagement between the connecting thread 223 and the internal thread.
