Description

Technical Field

[0001] This utility model relates to the field of display screen adjustment technology, specifically a broadcast switcher for precisely adjusting the angle of a display screen. Background Technology

[0002] A switcher is a widely used device in film and television production and live broadcasting. It allows operators to precisely control the switching and transmission of video signals. To facilitate efficient operation of the switcher, it is often connected to a display screen and integrated into a single unit. The large screen on the display screen allows for convenient viewing and display of the switcher's real-time status.

[0003] However, the traditional angle adjustment mechanism has a limited number of rotation adjustment levels. For the switcher's display screen, the rotation adjustment is not precise enough. Due to the inaccuracy of the display screen angle adjustment, it is difficult for the operator to accurately view and operate the switcher. In order to solve this problem, a switcher with precise adjustment of the display screen angle is proposed. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a switcher for precisely adjusting the angle of a display screen. It has the advantages of precisely adjusting the rotation angle of the display screen, and solves the problem that the traditional angle adjustment mechanism has limited range of rotation adjustment. For the display screen of the switcher, the rotation adjustment is not precise enough. Usually, due to the inaccuracy of the display screen angle adjustment, the operator has difficulty in accurately viewing and operating the switcher.

[0006] (II) Technical Solution

[0007] To achieve the aforementioned goal of precisely adjusting the rotation angle of the display screen, this utility model provides the following technical solution:

[0008] A switcher for precisely adjusting the angle of a display screen includes a housing, a cover plate rotatably connected to the rear side of the housing, and a switcher embedded in the upper end of the housing. A display screen is embedded in the plane of the cover plate relative to the housing, and the switcher is electrically connected to the display screen.

[0009] Connecting rods are provided on both sides of the angle between the outer shell and the cover plate. Fixing components are installed on both sides of the cover plate. Sliding components are slidably provided on both sides of the switching platform. Each connecting rod is rotatably connected to the sliding component on one side and to the fixing component on the other side.

[0010] The upper end of the outer shell has guide grooves on both sides to guide the sliding parts. Each guide groove is equipped with a positioning plate. The upper end of the positioning plate has a toothed rack on one side near the display screen and a smooth plane on the other side.

[0011] A positioning element is rotatably connected to the front side of the sliding element, and the lower end of the positioning element cooperates with the part of the positioning plate with a toothed rack.

[0012] The preferred technical solution of this utility model is that the cover plate is hollow inside and has mating grooves on both sides of the plane relative to the outer shell.

[0013] The preferred technical solution of this utility model is that each of the mating grooves has a number of heat dissipation holes on the inner wall near the display screen.

[0014] A preferred embodiment of this invention is that each of the sliding components has a first mounting block fixed at its upper end and a second mounting block fixed at its front end.

[0015] The preferred technical solution of this utility model is that the first mounting block is rotatably connected to the connecting rod, and the second mounting block is rotatably connected to the positioning member.

[0016] The preferred technical solution of this utility model is that each of the sliding members has a slider on its left and right sides, and each of the guide grooves has a groove on its left and right sides, and the slider and the groove cooperate with each other.

[0017] The preferred technical solution of this utility model is that the positioning component includes a square plate, a hook, and a protrusion. The hook is fixedly installed at the front end of the square plate, the protrusion protrudes above the square plate, and the lower end of the hook cooperates with the rack on the positioning plate.

[0018] The preferred technical solution of this utility model is that the protrusion is made of an inner ring magnet and an outer ring anti-slip strip, and the protrusion can be magnetically attracted to the connecting rod by rotating through the second mounting block.

[0019] (III) Beneficial Effects

[0020] Compared with the prior art, this utility model provides a broadcast switcher for precisely adjusting the angle of the display screen, which has the following advantages:

[0021] This precisely adjustable display screen angle control switcher connects and supports the cover plate to the outer casing via a connecting rod. Since the connecting rod is rotatably connected to a fixing component on the cover plate, rotating the cover plate causes the connecting rod to move, resulting in a sliding component that slides within a guide groove moving along with the connecting rod. Simultaneously, a positioning component is rotatably connected to the sliding component. Under gravity, the positioning component engages with a rack on the positioning plate, thus fixing the cover plate in the rotational direction. To release the fixation, simply pull the protrusion on the positioning component, causing it to rotate until the protrusion contacts and attracts the bottom of the connecting rod, releasing the cover plate from the rotational direction fixation. This allows for convenient multi-angle adjustment and fixation of the display screen on the cover plate. Because the positioning plate is rack-shaped, it offers higher adjustment precision compared to traditional angle adjustment mechanisms, and the locking and unlocking processes are faster and more user-friendly.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0031] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0032] Please see Figure 1-6 A switcher for precisely adjusting the angle of a display screen includes a housing 1, a cover plate 2 rotatably connected to the rear side of the housing 1, and a switcher 3 embedded at the upper end. A display screen 4 is embedded on the plane of the cover plate 2 relative to the housing 1, and the switcher 3 is electrically connected to the display screen 4.

[0033] Connecting rods 8 are provided on both sides of the angle between the outer shell 1 and the cover plate 2. Fixing parts 7 are installed on both sides of the cover plate 2. Sliding parts 6 are slidably provided on both sides of the switching platform 3. Each connecting rod 8 is rotatably connected to the sliding part 6 on one side and to the fixing part 7 on the other side.

[0034] The upper end of the outer casing 1 has guide grooves 11 on both sides to guide the sliding member 6. Each guide groove 11 has a positioning plate 5 installed inside. The upper end of the positioning plate 5 has a toothed rack on one side near the display screen 4 and a smooth plane on the other side.

[0035] The front side of the sliding member 6 is rotatably connected to the positioning member 9, and the lower end of the positioning member 9 cooperates with the part of the positioning plate 5 that has a rack.

[0036] It should be noted that, generally, when observing the display screen 4, the angle between the cover plate 2 and the outer shell 1 needs to be greater than 90°. The positioning plate 5 has a toothed rack on one side near the display screen 4 and a smooth plane on the other side. When the angle between the cover plate 2 and the outer shell 1 is between 0° and 90°, the positioning member 9 is located on the smooth plane and does not have the effect of rotating and fixing the cover plate 2. When the angle between the cover plate 2 and the outer shell 1 is greater than 90°, the positioning member 9 moves above the toothed rack, and the hook 92 engages with the toothed rack, making the cover plate 2 unable to rotate. Thus, the positioning member 9 has the effect of rotating and locking the cover plate 2.

[0037] It should be further explained that the structural advantage mentioned above is that when the angle between the cover plate 2 and the outer shell 1 is between 0° and 90°, the cover plate 2 can rotate quickly. Compared with the traditional cover plate 2 rotation structure, this structure makes the cover plate 2 rotate more easily, eliminating unnecessary fixing structures. When the angle is greater than 90°, the rack and positioning member 9 work together to precisely control the rotation angle of the cover plate 2. Each time the positioning member 9 moves to the next rack and engages with it, it is a stop, which provides higher precision in fixing the rotation angle of the cover plate 2, thereby realizing multi-angle rotation adjustment of the display screen 4.

[0038] In this embodiment, the cover plate 2 is hollow inside and has mating grooves 21 on both sides of the plane relative to the outer shell 1.

[0039] It should be noted that the mating groove 21 is located on both sides of the display screen 4, and when the cover plate 2 and the outer shell 1 are closed, the mating groove 21 can hide the connecting rod 8, the sliding member 6 and the positioning member 9, so that the cover plate 2 and the outer shell 1 are tightly fitted.

[0040] In this embodiment, each mating groove 21 has several heat dissipation holes 211 on the inner wall near the display screen 4.

[0041] It should be noted that the heat dissipation hole 211 is connected to the inside of the cover plate 2, and a heat dissipation device can be installed inside the cover plate 2. The heat dissipation hole 211 facilitates heat exchange between the inside of the cover plate 2 and the outside, thereby cooling the display screen 4.

[0042] In this embodiment, each slider 6 has a first mounting block 62 fixed at its upper end and a second mounting block 63 fixed at its front end.

[0043] In this embodiment, the first mounting block 62 is rotatably connected to the connecting rod 8, and the second mounting block 63 is rotatably connected to the positioning member 9.

[0044] It should be noted that when the cover plate 2 is rotated, the sliding member 6 and the positioning member 9 move accordingly through the transmission of the connecting rod 8.

[0045] It should be further explained that when the cover plate 2 is opened to 90°, the positioning element 9 and the positioning plate 5 cooperate with each other, causing the cover plate 2 to be unable to rotate. The rack on the positioning plate 5 is obliquely toothed, that is, when the cover plate 2 is rotated open, the positioning plate 5 and the rack are locked together and cannot rotate. When the cover plate 2 is closed, due to the special structure of the rack, the end of the positioning element 9 that is away from the second mounting block 63 will jump continuously when it moves, so that the hook 92 will continuously disengage from the rack, thereby facilitating the closing of the cover plate 2.

[0046] In this embodiment, each slider 6 is provided with a slider 61 on the left and right sides, and each guide groove 11 is provided with a sliding groove 111 on the left and right sides, with the slider 61 and the sliding groove 111 cooperating with each other.

[0047] It should be noted that the sliding groove 111 and the slider 61 cooperate with each other, making the sliding member 6 slide more stably along the guide groove 11, which has a more stable effect on the transmission of the connecting rod 8 and the positioning member 9.

[0048] In this embodiment, the positioning component 9 includes a square plate 91, a hook 92, and a protrusion 93. The hook 92 is fixedly installed at the front end of the square plate 91, and the protrusion 93 protrudes above the square plate 91. The lower end of the hook 92 cooperates with the rack on the positioning plate 5.

[0049] It should be noted that the point where the hook 92 and the rack interact should be a pointed structure. The actual adjustment accuracy of this design is related to the size and density of the rack. At the same time, different rotation angles can be marked on the side of the guide groove 11 corresponding to different rack positions, making it more convenient for users to adjust the angle. If the viewing angle of the display screen 4 is good when the angle between the cover plate 2 and the outer shell 1 is 120°, the user only needs to rotate the cover plate 2 according to the angle marked on the side of the guide groove 11 next time.

[0050] In this embodiment, the protrusion 93 is made of an inner ring magnet and an outer ring anti-slip strip. The protrusion 93 can be magnetically attracted to the connecting rod 8 by rotating through the second mounting block 63.

[0051] It should be noted that when the cover plate 2 is rotated, the positioning part 9 will cooperate with the rack on the positioning plate 5 under the action of gravity, causing the cover plate 2 to be unable to rotate. The positioning part 9 is magnetically attached to the connecting rod 8 through the protrusion 93, so that the hook 92 is separated from the positioning plate 5, which makes it convenient to adjust the rotation angle of the cover plate 2.

[0052] In summary, this precise screen angle adjustment switcher connects and supports the cover plate 2 and the outer casing 1 via a connecting rod 8. Since the connecting rod 8 is rotatably connected to the fixing member 7 fixed on the cover plate 2, the connecting rod 8 moves with the cover plate 2 when it is rotated. This causes the sliding member 6, which slides within the guide groove 11, to move along with the connecting rod 8. Simultaneously, a positioning member 9 is rotatably connected to the sliding member 6. Under gravity, the positioning member 9 engages with the rack on the positioning plate 5, thus fixing the cover plate 2 in the rotational direction. To release the fixation, simply pull the protrusion 93 on the positioning member 9, causing it to rotate until the protrusion 93 contacts and attracts the bottom of the connecting rod 8, thus releasing the cover plate 2 from the rotational direction fixation. This facilitates multi-angle adjustment and fixation of the screen 4 on the cover plate 2. Because the positioning plate 5 is rack-shaped, its adjustment precision is higher than that of traditional angle adjustment mechanisms, and the release and fixation are faster, making it more convenient for users.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
