[0002] In today's digital age, audio and video display terminals, as key devices for information presentation, are widely used in various occasions, from home entertainment to commercial displays, from education and teaching to industrial control, and are indispensable in all these scenarios.

[0003] To adapt to diverse usage scenarios and user needs, audio-visual display terminals are constantly innovating in design. In actual use, users often need to move the display terminal to different locations; therefore, mobile audio-visual display terminals have emerged, with portable monitors being a common example. These portable monitors are often used for commercial displays and are frequently used in public places. While portable monitors offer great convenience, some issues still exist during their use.

[0004] These portable displays typically require a plug for power and signal transmission. When used in public places, the data cable connected to the plug is inevitably tripped by pedestrians, which can cause the plug to loosen and fall off. This not only affects the normal use of the device but may also interfere with or even cause data transmission loss, making it difficult to guarantee the stability and reliability of its use.

[0005] Therefore, an audio and video display terminal is proposed to solve the above problems. Utility Model Content

[0006] To overcome the above shortcomings, this utility model provides an audio and video display terminal, which aims to improve the problem that the plug of the mobile display in the prior art is easily loosened and detached due to pedestrians tripping over it, resulting in unstable use of the device and interference with data transmission.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an audio-visual display terminal, including a support frame, a universal wheel provided on the lower surface of the support frame, a support plate rotatably connected to the inner surface of the support frame, a display screen provided on the front surface of the support plate, a plug inserted into the bottom end of the display screen, a protective component provided on the lower surface of the support plate, and an adjustment component provided on the right end of the support frame;

A screw is fixedly connected to the output shaft of the motor. A positioning plate is threadedly connected to the outer wall of the screw. A sliding groove is provided on the front surface of the mounting plate. A sliding rod is slidably connected to the inner wall of the sliding groove. A protective plate is fixedly connected to the front surface of the sliding rod.

[0009] As a further description of the above technical solution:

[0010] The adjustment assembly includes a pull rod that passes through and is slidably connected to the right surface of the support frame. A disc is elastically connected to the inner wall of the right side of the support frame via a compression spring. A locking block is fixedly connected to the left surface of the disc. A locking groove is formed on the right surface of the support plate.

[0011] As a further description of the above technical solution:

[0012] The screw passes through and is rotatably connected to the lower surface of the fixed block, and the positioning plate is slidably connected to the rear surface of the mounting plate.

[0013] As a further description of the above technical solution:

[0014] The lower surface of the positioning plate is recessed and has an isosceles trapezoidal shape.

[0015] As a further description of the above technical solution:

[0016] The protective plate is sleeved on the outer wall of the plug. There are two sets of sliding rods and sliding grooves, and the two sets of sliding rods and sliding grooves are symmetrically distributed about the center line of the mounting plate.

[0017] As a further description of the above technical solution:

[0018] The opposing surfaces of the two sets of slide rods are elastically connected by a connecting spring.

[0019] As a further description of the above technical solution:

[0020] The disc is slidably connected to the inner wall of the support frame, and the disc is fixedly connected to the left surface of the pull rod.

[0021] As a further description of the above technical solution:

[0022] The card block is inserted into the inner wall of the card slot.

[0023] This utility model has the following beneficial effects:

[0024] 1. In this utility model, the protective component effectively protects the plug. A motor drives a screw, which moves a positioning plate. The special concave shape of the positioning plate presses against the sliding rod, causing the protective plate to fit over the outer wall of the plug. This prevents pedestrians from tripping over the data cable and causing the plug to detach, enhancing the stability of the device during use and ensuring the reliability of data transmission.

[0025] 2. In this utility model, with the cooperation of the adjustment component, pulling the lever can disengage the locking block from the slot and release the limit. Rotating the support plate can adjust the angle of the display screen. After releasing the lever, the locking block is reinserted into the slot and limited, so that the display screen can be displayed at different angles, which can meet the diverse viewing needs of users in different scenarios and improve the practicality of the device.

[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. 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.

[0034] Reference Figure 1 - Figure 2This utility model provides an embodiment of an audio-visual display terminal, including a support frame 1. A set of casters 2 are provided on the lower surface of the support frame 1, evenly distributed at the four corners of the lower surface of the support frame 1. A support plate 3 is rotatably connected to the inner surface of the support frame 1. A display screen 4 is provided on the front surface of the support plate 3. Both the casters 2 and the display screen 4 are existing technologies and can be implemented by those skilled in the art. Since they are existing technologies, they will not be described in detail in this case. The casters 2 are equipped with locking pedals for self-locking. A plug 5 is inserted into the bottom of the display screen 4, and the plug 5 is connected to an external power source or signal source. A protective component is provided on the lower surface of the support plate 3 to protect the plug 5 from accidental loosening. An adjustment component is provided on the right end of the support frame 1.

[0035] Reference Figure 2 - Figure 4 The protective component includes a mounting plate 61, which is fixedly connected to the lower surface of a support plate 3 by bolts. The lower surface of the support plate 3 has multiple sets of equally spaced mounting holes. The mounting plate 61 can be installed at different positions under the support plate 3 as needed. A fixing block 62 is fixedly connected to the rear surface of the mounting plate 61. A motor 63 is provided on the upper surface of the fixing block 62. A screw 64 is fixedly connected to the output shaft of the motor 63. Both the motor 63 and the screw 64 are existing technologies and can be implemented by those skilled in the art. The output shaft of the motor 63 can rotate in both directions, which can drive the screw 64 to rotate in the forward or reverse direction. A positioning plate 65 is threadedly connected to the outer wall of the screw 64. A sliding groove 601 is provided on the front surface of the mounting plate 61. A sliding rod 66 is slidably connected to the inner wall of the sliding groove 601. A protective plate 68 is fixedly connected to the front surface of the sliding rod 66. The sliding rod 66 and the protective plate 68 will move synchronously.

[0036] Reference Figure 2 - Figure 4 The screw 64 passes through and is rotatably connected to the lower surface of the fixing block 62. The positioning plate 65 is slidably connected to the rear surface of the mounting plate 61. The positioning plate 65 moves longitudinally. When the screw 64 rotates, it can drive the positioning plate 65 to move up and down. The lower surface of the positioning plate 65 is set in a concave shape, which is an isosceles trapezoid. The slide rod 66 contacts the inner surface of the concave part of the positioning plate 65. The higher the concavity, the shorter the left and right span. The protective plate 68 is sleeved on the outer wall of the plug 5 to fix the plug 5 and prevent pedestrians from accidentally falling in. To prevent the data cable connected to plug 5 from tripping and causing plug 5 to fall off, this design enhances stability during use. Both slide rods 66 and slide grooves 601 are provided in two sets, which are symmetrically distributed about the center line of mounting plate 61. The opposite surfaces of the two sets of slide rods 66 are elastically connected by connecting springs 67. When the two sets of slide rods 66 are not squeezed by positioning plate 65, the connecting springs 67 will push the two sets of slide rods 66 to open. At this time, the protective plate 68 will also open, making it convenient to unplug or plug in plug 5.

[0037] Reference Figure 1 , Figure 2 , Figure 5 The adjustment component includes a pull rod 71, the right end of which is protruding for easy gripping. The pull rod 71 passes through and is slidably connected to the right surface of the support frame 1, allowing for lateral movement. The inner wall of the right side of the support frame 1 is elastically connected to a disc 72 via a compression spring 74. When the disc 72 moves to the right, it compresses the compression spring 74, generating a reaction force. A locking block 73 is fixedly connected to the left surface of the disc 72. A locking groove 701 is provided on the right surface of the support plate 3. The locking block 73 and the locking groove 701 fit together, and the left edge of the locking block 73 is chamfered to facilitate its insertion into the locking groove 701. Multiple sets of locking grooves 701 are provided, arranged in a circular array with the center of the support plate 3 as the origin. This ensures that when the support plate 3 rotates, there are appropriate positions for the locking grooves 701 and the locking blocks 73 to align.

[0038] Reference Figure 1 , Figure 2 , Figure 5 The disc 72 is slidably connected to the inner wall of the support frame 1 and moves laterally. The disc 72 is fixedly connected to the left surface of the pull rod 71. The locking block 73 is inserted into the inner wall of the slot 701, which can limit the support plate 3 and ensure the stability of the orientation of the display screen 4.

[0039] Working principle: The device can be easily moved to a suitable position using the casters 2. When the device reaches the desired position, step on the locking pedal to lock the casters 2 and ensure the device is stable.

[0040] Then, plug 5 is inserted. When protection of plug 5 is needed, motor 63 is started, driving screw 64 to rotate forward. Positioning plate 65, which is threaded to the outer wall of screw 64, moves downward on the rear surface of mounting plate 61. The lower surface of positioning plate 65 is concave (isosceles trapezoid). As positioning plate 65 descends, its concave area gradually presses against sliding rod 66, causing the two sets of sliding rods 66 to come together. This, in turn, moves protective plate 68 until it fits onto the outer wall of plug 5, securing plug 5 and preventing pedestrians from accidentally tripping over the data cable and causing plug 5 to fall off. When plug 5 needs to be plugged in or unplugged, motor 63 is reversed, and screw 64 drives positioning plate 65 to rise. The pressure of positioning plate 65 on sliding rod 66 disappears. At this time, connecting spring 67 pushes the two sets of sliding rods 66 to move to both sides, and protective plate 68 opens accordingly, facilitating plugging and unplugging of plug 5.

[0041] When the angle of the display screen 4 needs to be adjusted, pull the lever 71 to the right. The lever 71 drives the disc 72 to move to the right simultaneously. The disc 72 compresses the spring 74 and disengages the locking block 73 from the current slot 701. At this time, the support plate 3 can be rotated to rotate the display screen 4 to the appropriate angle. Release the lever 71, and the spring 74 returns to its original deformation, pushing the disc 72 to the left, causing the locking block 73 to insert into the corresponding slot 701. This limits the support plate 3, ensuring that the display screen 4 is stable at the adjusted angle, meeting the user's viewing needs from different angles.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
