DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making any creative efforts shall fall within the scope of protection of this application.

[0031] Example 1

[0032] The present invention relates to a ground beam device, which is applied to a large LED display screen installation system.

[0033] Existing large-scale LED display screens are usually assembled by assembling multiple LED display modules 31. Each LED display module 31 is fixed on an LED display screen box. Multiple LED display screen boxes are spliced together to complete the splicing of LED display modules 31 and finally assembled into a large-scale LED display screen. Therefore, the LED large-scale display screen installation system usually includes LED display modules 31 and LED display screen boxes. In order to improve the wind resistance and bending resistance of the LED large-scale display screen installation system, a wind resistance frame 30 is usually used, such as Figure 2 As shown, the windage rack 30 is arranged on one side of the LED display housing, and the LED display module 31 is arranged on the other side of the LED display housing. The windage rack 30 includes an upper component 32, a lower component 38, a first fixing rod, a second fixing rod, and a support rod 33. The support rod 33 can be opened or closed between the first and second fixing rods. The upper and lower adjacent support rods 33 are connected by a knob sleeve 35 and a support screw 34. The upper component 32 and the lower component 38 are connected by the first and second fixing rods. The upper and lower adjacent components 32 and 38 are connected by a windage rack latch block 36 and a windage rack latch slot.

[0034] When the LED large-scale display screen installation system is applied to outdoor rental venues, there is an uneven ground problem. The existing solution is to use a spirit level to find the horizontal surface for the screen installation and level the ground before setting up the screen. However, there are problems such as complex operation, reduced efficiency and insufficient stability.

[0035] In order to solve the above technical problems, this embodiment provides a ground beam device, such as Figure 1 As shown, including:

[0036] A ground beam support frame 10, wherein the ground beam support frame 10 is provided with a first adjustable foot 11 and a second adjustable foot 12;

[0037] A support base 20, wherein a third adjustable foot 21 is provided on the support base 20;

[0038] The support seat 20 is detachably connected to the ground beam support frame 10;

[0039] The first adjustable foot 11 and the second foot 12 on the ground beam support frame 10 and the third adjustable foot 21 on the support base 20 form a three-point support structure in contact with the ground.

[0040] The ground beam device includes two parts: a ground beam support frame 10 and a support base 20. The ground beam device is provided with three ground feet as a whole, two of which are provided on the ground beam support frame 10. The ground beam support frame 10 as a whole corresponds to the first fixing rod and the second fixing rod of the windproof frame. There is also one ground foot provided on the support base 20. The ground foot on the support base 20 corresponds to the position of the support rod 33 of the fully deployed wind resistance frame 30. Figure 3 、 Figure 4 、 Figure 5 As shown, the three feet of the ground beam device correspond to the three rod positions of the fully deployed wind resistance frame 30, ensuring that the wind resistance frame 30 is perfectly supported by the ground beam device in the fully deployed state.

[0041] At least two of the three feet of the ground beam device are adjustable. That is, when the height of one foot is constant, the height of the other two feet can be adjusted to achieve leveling of the ground beam device. After the ground beam device is leveled, the vertical construction and stable structure of the wind resistance frame 30 and the LED display box built thereon are guaranteed. In particular, the three-point support structure of the three feet also ensures the bottom structural stability of the large LED display installation system.

[0042] Specifically, the first adjustable foot 11 is a foot with vertically adjustable height, and the second foot 12 is a fixed foot or a foot with vertically adjustable height. The height of the vertically adjustable foot is adjusted by adjusting the dial 111. The third adjustable foot 21 is a foot with vertically adjustable height.

[0043] Preferably, two upper and lower height-adjustable feet of the same structure are provided at the bottom of the ground beam support frame 10. The upper and lower height-adjustable feet are adjusted in height by a horizontal adjustment dial 111. The adjustment of this setting method is more convenient. The upper and lower height-adjustable feet on the support seat 20 are adjusted by rotating the screw on the foot with the threaded hole of the support beam 22 of the support seat 20. Since there is no obstruction above the support seat 20, the structure is simpler, more stable and lower in cost.

[0044] Preferably, a level bubble 15 is provided on the ground beam support frame 10 , and when adjusting the level of the ground beam support frame 10 , the leveling can be completed quickly and accurately by observing the bubble position of the level bubble 15 .

[0045] When setting the connection structure between the ground beam support frame 10 and the wind resistance frame 30, the ground beam support frame 10 adopts a pin block 13 and a pin slot 39 structure that are consistent with the wind resistance frame 30. The pin block 13 on the ground beam support frame 10 and the pin slot 39 at the bottom of the wind resistance frame 30 are used to achieve quick and accurate docking. At the same time, the ground beam support frame 10 adopts a structure consistent with the wind resistance frame 30, which reduces the design cost, manufacturing cost and installation cost of the ground beam support frame 10. Because the installation of the ground beam support frame 10 and the wind resistance frame 30 is consistent with the installation between the wind resistance frames 30, when the construction personnel start installing from the ground beam device, it is completely consistent with the subsequent installation of the wind resistance frame 30, which can reduce the difficulty and complexity of the construction personnel's operation and improve their work efficiency.

[0046] Similarly, the locking handle 37 provided on the ground beam support frame 10 is also consistent in structure with the locking handle 37 on the wind resistance frame 30 , and the locking handle 37 is rotated to lock or unlock the latch block 13 and the latch slot 39 structure.

[0047] Specifically, the ground beam support frame 10 is provided with a ground beam screw 14, and the support base 20 is provided with a support spiral sleeve 24. The ground beam support frame 10 and the support base 20 are detachably connected via the ground beam screw 14 and the support spiral sleeve 24. That is, the ground beam support frame 10 and the support base 20 adopt a spiral sleeve and screw connection structure, which is simple to operate and stable. In particular, the structure of the spiral sleeve and screw between the ground beam support frame 10 and the support base 20 is consistent with the structure of the spiral sleeve and screw on the wind resistance frame 30, reducing the design cost, manufacturing cost, and installation cost of the ground beam support frame 10. Because the installation of the ground beam support frame 10 and the support base 20 is consistent with the installation of the wind resistance frame 30, the installation of the ground beam device by construction personnel is completely consistent with the subsequent installation of the wind resistance frame 30, which can reduce the difficulty and complexity of the operation for construction personnel and improve their work efficiency.

[0048] Specifically, the support base 20 has two base crossbars 25, each of which is detachably connected to the two ground beam screws 14 on the ground beam support frame 10 via support spiral sleeves 24. The two base crossbars 25 are connected via a load-bearing beam 23 and at least one support beam 22. The load-bearing beam 23 is provided with a support rotating sleeve, which is detachably connected to the support screw 34 at the bottom of the support rod 33 of the wind resistance frame 30. The third adjustable foot 21 is provided on the support beam 22. This structure is stable and has low manufacturing costs.

[0049] The ground beam assembly includes a detachably connected ground beam support frame 10 and a support base 20. The ground beam support frame 10 has two footings at its base, and the support base 20 has one footing at its base. These three footings form a stable three-point support structure, increasing the bottom support area of the LED display cabinet and improving the stability of the three-point support structure. Furthermore, at least two of the three footings are height-adjustable. Adjusting the height of the three footings allows for stable contact with surfaces of varying heights. This means the ground beam assembly is highly adaptable to varying surface heights. The ground beam assembly offers advantages such as a detachable structure and quick and stable installation.

[0051] This embodiment provides an LED display screen installation system, in which a ground beam device is provided at a fixed position at the bottom of the LED display screen installation system.

[0052] The ground beam assembly of this LED display installation system includes a detachably connected ground beam support frame 10 and a support base 20. The ground beam support frame 10 has two footings at its base, and the support base 20 has one footing at its base. These three footings form a stable three-point support structure, increasing the bottom support area of the LED display cabinet and improving the stability of the three-point support structure. Furthermore, at least two of the three footings are height-adjustable. Adjusting the height of the three footings allows for stable contact with surfaces of varying heights. This means that the ground beam assembly of this solution is highly adaptable to varying surface heights. The ground beam assembly offers advantages such as a detachable structure and quick and stable installation.
