Description

Technical Field

[0001] The utility model relates to the technical field of television interview stands, in particular to an interview stand for broadcasting and television. Background Art

[0002] Radio and television are the media that broadcast audio and video programs to a wide area through radio waves or wires, collectively referred to as broadcasting; only broadcasting is called audio broadcasting; broadcasting of images and sound is called television broadcasting; in a narrow sense, broadcasting is the use of radio waves and wires to transmit content only with sound; in a broad sense, broadcasting includes what we usually think of as sound-only broadcasting and television with both sound and images; and in the process of radio and television interviews, a fixed device is often needed to fix the interview equipment, but the existing radio and television interview fixed racks have some shortcomings, such as:

[0003] Publication No.: CN206555657U A radio and television interview stand, the radio and television interview stand has the effect of easy disassembly, easy placement and transportation, and has a stable and firm effect, and has a compact structure, strong practicality, and is easy to promote and use. However, in actual use, since the device supports the interview equipment through a sliding component, it is often necessary to fix it manually in actual use, thereby reducing the firmness of the device when fixing the interview equipment;

[0004] Therefore we propose a radio and television interview stand to solve the above-mentioned problems. Utility Model Content

[0005] The purpose of the utility model is to provide an interview stand for radio and television, so as to solve the problem raised in the above background technology that most of the interview equipment fixing mechanisms on the market currently support the interview equipment through sliding components, so in actual use, they often need to be fixed manually, thereby reducing the firmness of the device when fixing the interview equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an interview stand for radio and television, comprising a device body, a rotating shaft connected to the inside of the device body, the rotating shaft is located at the top of the inside of the device body, and a twisting roller is connected to the left side of the rotating shaft, and the twisting roller is located on the left side of the device body; two groups of first bevel gears are connected to the outside of the twisting roller, and the rear side of the first bevel gear is connected to the second bevel gear, and the rear side of the second bevel gear is provided with a sprocket, the right side of the sprocket is meshed with a toothed shaft, and the top of the toothed shaft is connected to a fixing plate;

[0008] By twisting the twisting roller, the first bevel gear is driven to rotate. Since the first bevel gear is meshed with the second bevel gear, the second bevel gear will drive the sprocket to rotate, so that the sprocket drives the toothed shaft to rise and fall, and the toothed shaft lifts the fixed plate. By setting the first telescopic rod, the fixed plate can drive the first telescopic rod to rise and fall while the fixed plate is rising and falling, so that the fixed plate can be more stable when rising and falling.

[0009] As the preferred technical solution of the utility model, two groups of limit plates are provided on the top of the fixed plate, and two groups of spring clips are connected to the top of the limit plate, and the spring clips are located on the top of the fixed plate; the rear side of the spring clips is rotationally connected to the limit plate through a torsion spring shaft.

[0010] The adoption of the above technical solution can make it more convenient to use the fixing plate to limit the television interview equipment, and by arranging a spring buckle on the top of the limiting plate, the limiting plate can fix the television interview equipment through the spring buckle.

[0011] As a preferred technical solution of the utility model, a threaded rod is connected inside the fixed plate, and a first limiting groove and a second limiting groove are connected to the outside of the threaded rod, and the bottom of the first limiting groove and the second limiting groove are threadedly connected to the threaded rod through a threaded sleeve, and the thread directions of the threaded sleeves arranged at the bottom of the first limiting groove and the second limiting groove are opposite.

[0012] By adopting the above technical solution, when the user twists the threaded rod, the threaded rod will drive the first limiting groove and the second limiting groove to move toward each other, thereby making the device more convenient when fixing television interview equipment of different sizes.

[0013] As a preferred technical solution of the utility model, a limit seat is connected to the bottom of the device body, and two sets of pulleys are connected to the bottom of the limit seat, and the pulleys are connected to the limit seat through a rotating seat.

[0014] By adopting the above technical solution, when the bottom of the device body is attached to the ground, it can be attached through the limit seat, and when the device is moved, it can be moved by taking out the pulley.

[0015] As a preferred technical solution of the utility model, a set of fixed shafts are connected to the rear sides of the second bevel gear and the sprocket, and the fixed shafts are connected to the placement box.

[0016] By adopting the above technical solution, the second bevel gear and the sprocket can be fixed by the fixed shaft during the rotational movement, so that the device can be more stable during operation and the firmness of the device is increased.

[0019] As a preferred technical solution of the utility model, two groups of rotating rods are provided on the front side of the device body, and the bottom of the rotating rod is connected to the second telescopic rod, and the bottom of the second telescopic rod is connected to the fixed base.

[0020] The above technical solution enables the user to adjust the second telescopic rod so that the fixed base is fitted and fixed to the ground, thereby increasing the stability of the device during use and avoiding the problem of requiring manual support.

[0021] Compared with the prior art, the utility model has the following beneficial effects: the first bevel gear is driven to rotate by twisting the twisting roller, and since the first bevel gear is meshed with the second bevel gear, the second bevel gear drives the sprocket to rotate, so that the sprocket drives the toothed shaft to rise and fall, so that the toothed shaft lifts and lowers the fixed plate, and through the setting of the first telescopic rod, the fixed plate can drive the first telescopic rod to rise and fall while the fixed plate is lifting and lowering, so that the fixed plate can be more stable when lifting and lowering;

[0022] 1. By arranging a limit plate on the top of the fixing plate, the fixing plate can be more convenient when limiting the TV interview equipment, and by arranging a spring buckle on the top of the limit plate, the limit plate can drive the spring buckle to press down through the torsion spring shaft, so as to better fix the bottom plate of the interview equipment;

[0023] 2. Through the setting of the threaded rod, when the user twists the threaded rod, the threaded rod will drive the first limiting groove and the second limiting groove to move toward each other, so that the device can be more convenient when fixing television interview equipment of different sizes;
