Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to an LED display screen installation and fixing structure. Background Art

[0002] LED display is a flat panel display, composed of small LED module panels, used to display text, images, videos, video signals and other information. LED light-emitting diode is a display method that controls semiconductor light-emitting diodes. When electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes, used as indicator lights in circuits and instruments, or to form text or digital displays. Gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitrogen diodes emit blue light. A fixed structure is required during the installation of LED display screens.

[0003] However, the existing fixed structure has fixed installation points that cannot be moved flexibly, and the fixing method is relatively rigid, which results in the inability to install LED screens of different sizes during use, thereby reducing the installation efficiency, which not only brings trouble to the staff, but also reduces the staff's work efficiency. For this reason, we propose an LED display installation fixing structure to solve the above problems. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] See also Figure 1-3 The utility model discloses a LED display screen installation and fixing structure, comprising a mounting frame 1, a shell 5 is fixedly mounted on the surface of the mounting frame 1, a hand crank 4 is movably connected to the right side of the shell 5, a positive and negative threaded rod 11 is fixedly connected to the left side of the hand crank 4, and a threaded sleeve 14 is threadedly connected to the left side of the positive and negative threaded rod 11 through the inner cavity of the shell 5, a support column 15 is fixedly connected to the surface of the threaded sleeve 14, and a fixing plate 18 is fixedly connected to the surface of the support column 15, a mounting shell 6 is fixedly mounted on the surface of the fixing plate 18, a mounting plate 9 is inserted into the inner cavity of the mounting shell 6, and a display screen body 7 is fixedly connected to the surface of the mounting plate 9.

[0022] Through the above technical solution, by adding the hand crank 4, it is convenient to drive the forward and reverse threaded rods 11 to rotate, so that the forward and reverse threaded rods 11 drive the threaded sleeve 14 to move inward, which can effectively drive the installation shell 6 to move, and facilitate the display screen body 7 to be plugged in. It can be suitable for the installation of display screen bodies 7 that are not the same size as the model, thereby improving the installation efficiency of the display screen body 7, and also solving the installation troubles of the staff.

[0023] Specifically, a second threaded hole is formed at the bottom of the side of the mounting plate 9 , a first threaded hole 12 is formed at the side of the mounting shell 6 , and the inner cavities of the second threaded hole and the first threaded hole 12 are threadedly connected with locking bolts 8 .

[0024] Through the above technical solution, by adding the first threaded hole 12, the second threaded hole and the locking bolt 8, it is convenient to lock the mounting plate 9, so as to achieve the installation of the display screen body 7.

[0025] Specifically, both ends of the inner cavity of the housing 5 are provided with a slide groove 10 , both ends of the threaded sleeve 14 are fixedly connected with a slider 13 , and the surface of the slider 13 is slidably connected in the inner cavity of the slide groove 10 .

[0026] Through the above technical solution, by adding the slide groove 10, the sliding stability of the slider 13 is improved.

[0027] Specifically, first mounting blocks 3 are fixedly connected to both sides of the back side of the housing 5 , and first mounting bolts 2 are disposed on the surface of the first mounting blocks 3 .

[0028] Through the above technical solution, by adding the first mounting block 3 and the first mounting bolt 2, the housing 5 can be easily disassembled and assembled.

[0029] Specifically, the second mounting blocks 17 are fixedly connected around the fixing plate 18 , and the surface of the second mounting blocks 17 is provided with second mounting bolts 16 .

[0030] Through the above technical solution, by adding the second mounting block 17 and the second mounting bolt 16, it is convenient to disassemble and assemble the mounting shell 6.

[0031] The working principle of the utility model is: firstly, Figure 1 As shown in the figure, it is the state after the display screen body 7 is installed. When the size of the display screen is different and the angular position of the mounting shell 6 needs to be adjusted, the user holds the hand crank 4 and drives the positive and negative threaded rod 11 to rotate through the hand crank 4. Since the threads on the surfaces of the positive and negative threaded rod 11 are in opposite directions, the two threaded sleeves 14 can be driven to move in opposite directions. For example, when the positive and negative threaded rod 11 rotates, since the threads on the surfaces of the positive and negative threaded rod 11 and the threads in the inner cavity of the threaded sleeve 14 are threadedly connected, the threaded sleeve 14 on the left side of the surface of the positive and negative threaded rod 11 moves to the right, and at the same time, the threaded sleeve 14 on the right side of the surface of the positive and negative threaded rod 11 moves to the left. When the support column 15 moves, the support column 15 drives the mounting shell 6 to move to the specified position, and the position of the mounting shell 6 can be effectively adjusted to facilitate the insertion of the display screen body 7, which can be suitable for the installation of the display screen body 7 that is smaller than the model size, thereby improving the installation efficiency of the display screen body 7. Then the user inserts the mounting plate 9 on the back of the display screen body 7 into the inner cavity of the mounting shell 6, and then takes out the locking bolt 8. By rotating the locking bolt 8, it is inserted into the first threaded hole 12 and the second threaded hole on the side of the mounting plate 9, thereby locking the mounting plate 9 and limiting it, and the display screen body 7 can be quickly installed, thereby improving the installation efficiency of the staff.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
