[0031] To further understand the content of the present utility model, the present utility model will be described in detail in combination with the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model rather than limiting it.

[0032] The following combines the attached Figures 1-5A further detailed description is given to this embodiment.

[0033] As Figure 1 shown, a bracket for a video terminal in this embodiment includes a bottom plate 100. Opposite support columns 110 are provided on the bottom plate 100. A plurality of insertion holes 111 are formed in the opposite side walls of the two support columns 110 along their height directions. The bottom plate 100 is further provided with a slidable mounting plate 120 for mounting a display screen. A box body 200 is provided on one side surface of the mounting plate 120 and between the two support columns 110. A cavity 301 is provided in the box body 200. Opposite insertion rods 310 are provided in the cavity 301. A driving assembly is provided in the cavity 301 for driving one end of the two insertion rods 310 to insert into the corresponding insertion holes 111. A fixing plate 130 for mounting the video conferencing terminal body is provided on the upper end surface of the mounting plate 120. A lifting assembly is provided on the fixing plate 130 for lifting and adjusting the fixing plate 130.

[0034] In this embodiment, by mounting the display screen on the mounting plate 120, when the height of the display screen needs to be adjusted, by driving the box body 200 to slide between the two support columns 110, the height of the display screen can be adjusted. When the position of the display screen is adjusted to a suitable position, by driving the driving assembly to move the insertion rods 310 in the box body 200, so that one end of the insertion rods 310 inserts into the corresponding insertion holes 111, the positioning of the box body 200 between the two support columns 110 can be realized. At this time, the height of the display screen on the mounting plate 120 is positioned;

[0035] Among them, by driving the driving assembly to drive one end of the insertion rod 310 to insert into the corresponding insertion hole 111, the adjusted height of the display screen can be positioned. Compared with the existing screw mounting method, when the bracket of this video terminal is actually used, the lifting adjustment of the mounting plate 120 is more convenient, thus facilitating actual use;

[0036] Among them, the support columns 110 are fixedly mounted on the bottom plate 100, and the box body 200 is fixedly mounted on the mounting plate 120. When the insertion rods 310 in the box body 200 insert into the corresponding insertion holes 111, the installation of the display screen on the bottom plate 100 can be realized;

[0037] Among them, when the size of the display screen on the mounting plate 120 is relatively large, the display screen may block the video conferencing terminal body on the fixing plate 130, thus affecting the use of the video conferencing terminal body. At this time, by adjusting the lifting of the fixing plate 130 through the lifting assembly, the video conferencing terminal body is lifted to a certain height, so as to avoid the relatively large display screen blocking the video conferencing terminal body;

[0038] During actual use, a plurality of positioning grooves 112 are formed in the support column 110 along its height direction, and positioning blocks 121 are fixedly installed on the side walls of the mounting plate 120. When the mounting plate 120 is adjusted to a suitable height, by inserting both ends of the positioning block 121 into the corresponding positioning grooves 112, the insertion rods 310 in the box body 200 can just correspond to the corresponding insertion holes 111. At this time, the driving assembly can drive the insertion rods 310 to accurately insert into the corresponding insertion holes 111, thereby improving the actual use effect. At the same time, when the positioning block 121 is inserted into the positioning groove 112, the positioning block 121 can share a certain weight for the two insertion rods 310, thereby improving the installation stability of the mounting plate 120.

[0039] As Figures 1-3 shown, in this embodiment, sliding blocks 320 located in the cavity 301 are provided on both insertion rods 310, and first inclined surfaces 321 are formed on the sliding blocks 320;

[0040] The driving assembly includes a driving cylinder 210 provided on the upper end surface of the box body 200. A driving cavity 331 is provided in the driving cylinder 210. A driving rod 390 that extends out of the driving cylinder 210 upward and is slidable is provided in the driving cavity 331. The lower end of the driving rod 390 extends into the cavity 301. A driving plate 340 is provided at the lower end of the driving rod 390. Second inclined surfaces 341 that cooperate with the corresponding first inclined surfaces 321 are provided on the opposite side walls of the driving plate 340. A circular plate 351 is provided on the driving rod 390 located in the driving cavity 331. A first spring 350 is sleeved on the driving rod 390 above the circular plate 351. The first spring 350 is used to push the driving plate 340 on the driving rod 390 downward, so that one end of the two insertion rods 310 is inserted into the corresponding insertion hole 111. A limiting member for limiting the downward movement of the driving plate 340 is provided on the lower end surface of the box body 200. A moving member for driving one end of the two insertion rods 310 to slide out of the insertion hole 111 is further provided in the cavity 301.

[0041] In this embodiment, through the settings of the sliding block 320, the first inclined surface 321, the driving cylinder 210, the driving cavity 331, the driving rod 390, the driving plate 340, the second inclined surface 341, the circular plate 351, the first spring 350, the moving member and the limiting member, by fixedly installing the sliding block 320 on the insertion rod 310, fixedly installing the driving cylinder 210 on the box body 200, fixedly installing the driving plate 340 on the driving rod 390, and fixedly installing the circular plate 351 on the driving rod 390, when the first spring 350 pushes the driving rod 390 downward through the circular plate 351, the driving rod 390 drives the driving plate 340 to move downward. At this time, the second inclined surface 341 on the driving plate 340 squeezes the first inclined surface 321, so that the sliding block 320 can drive the corresponding insertion rod 310 to move away from each other, thereby realizing that one end of the insertion rod 310 is inserted into the corresponding insertion hole 111;

[0042] Wherein, the side wall of the driving plate 340 is in sliding fit with the side wall of the cavity 301, so as to prevent the driving plate 340 from rotating and affecting the extrusion of the driving plate 340 on the slider 320;

[0043] Wherein, a handle 220 for pulling the driving rod 390 upward is fixedly installed on the protruding end of the driving rod 390. By pulling the driving rod 390 upward through the handle 220, the extrusion of the driving plate 340 on the slider 320 is released. At this time, the moving member can drive one end of the inserting rod 310 to slide out of the inserting hole 111, releasing the fixation of the box body 200, so that the height of the display screen on the mounting plate 120 can be continuously adjusted through the box body 200;

[0044] During actual use, when one end of the inserting rod 310 is inserted into the corresponding inserting hole 111, the handle 220 may be accidentally touched, resulting in the release of the extrusion of the driving plate 340 on the slider 320. At this time, the position of the driving plate 340 is limited by the limiting member, so that in the case of accidentally touching the handle 220, the driving plate 340 can still extrude the slider 320, thus preventing the box body 200 from being released from the fixation between the two support columns 110 due to accidentally touching the handle 220.

[0045] As Figures 1-3 shown, in this embodiment, pushing plates 360 are provided on the inserting rods 310;

[0046] The moving member includes a second spring 370 sleeved on the inserting rod 310. The second spring 370 is used to move the pushing plate 360 to realize the sliding out of one end of the inserting rod 310 from the inserting hole 111.

[0047] In this embodiment, through the arrangement of the pushing plate 360 and the second spring 370, by fixedly installing the pushing plate 360 on the inserting rod 310, when the driving plate 340 releases the extrusion on the slider 320, the second spring 370 pushes the inserting rods 310 to approach each other through the pushing plate 360, so that one end of the inserting rod 310 slides out of the inserting hole 111, releasing the fixation of the box body between the two support columns 110;

[0048] Wherein, the elastic force of the first spring 350 is greater than the elastic force of the two second springs 370, so that in the initial state, when the first spring 350 pushes the driving plate 340, the driving plate 340 can extrude the two sliders 320 to move away from each other, so that the two inserting rods 310 can be inserted into the corresponding inserting holes 111;

[0049] During actual use, a card slot is formed on the side wall of the cavity 301 along the moving direction of the inserting rod 310, and a card block that is fixedly installed on the pushing plate and is clamped into the card slot is provided. The card block is limited by the card slot, so that the movement of the pushing plate 360 in the cavity 301 is more stable, and thus the inserting rod 310 can be better driven to move.

[0050] As Figures 1-5 shown, in this embodiment, a limiting rod 380 with one end extending out of the box body 200 is provided on the lower end surface of the driving board 340. A limiting plate 400 is provided on the extending end of the limiting rod 380, and opposite limiting blocks 500 are provided on the side wall of the limiting plate 400;

[0051] The limiting member includes a first cylinder 410 rotatably provided on the box body 200. A first circular cavity 411 with an upward opening is provided in the first cylinder 410. Opposite limiting grooves 412 for the corresponding limiting blocks 500 to be inserted are provided on the side wall of the first circular cavity 411 along its height direction. Grooves 413 are provided at the lower end parts of the limiting grooves 412. The first cylinder 410 rotates to insert the limiting blocks 500 in the limiting grooves 412 into the grooves 413, so as to realize the limitation of the driving board 340.

[0052] In this embodiment, through the settings of the limiting rod 380, the limiting plate 400, the limiting blocks 500, the first cylinder 410, the first circular cavity 411, the limiting grooves 412 and the grooves 413, the limiting rod 380 is fixedly installed on the driving board 340, the limiting plate 400 is fixedly installed on the limiting rod 380, the limiting blocks 500 are opposite and fixedly installed on the limiting plate 400, and the upper end part of the first cylinder 410 is rotatably installed on the lower side surface of the box body 200 through a bearing. In its initial state, when the driving board 340 moves downward to make the inserting rod 310 insert into the corresponding inserting hole 111, at this time, the limiting blocks 500 are located at the lowest end of the limiting grooves 412. At this time, by rotating the first cylinder 410, the limiting blocks 500 are rotated into the corresponding grooves 413, so as to realize the fixation of the position of the driving board 340. At this time, the driving board 340 can always keep squeezing the slider 320, and pulling the handle 220 cannot drive the driving rod 390 to move upward;

[0053] Among them, when it is necessary to release the limitation of the driving board 340, by rotating the first cylinder 410, the limiting blocks 500 are rotated from the grooves 413 into the limiting grooves 412. At this time, the grooves 413 release the limitation of the driving board 340;

[0054] It should be noted that the limiting plate 400 can be attached to the lower side surface of the box body 200 to limit the upward movement of the limiting rod 380, so as to ensure that the limiting blocks 500 are always located in the corresponding limiting grooves 412, which is beneficial to the rotation and use of the first cylinder 410;

[0055] Among them, a convex block 430 is fixedly installed on the lower end surface of the first cylinder 410, and the convex block 430 is convenient for driving the first cylinder 410 to rotate;

[0056] In actual use, a second cylinder 420 is fixedly mounted on the lower end surface of the box body 200, and a second circular cavity with openings at both ends is opened in the second cylinder 420. The second cylinder 420 is sleeved on the first cylinder 410, so that the first cylinder 410 and the protrusion 430 are both located in the second circular cavity, thereby avoiding accidental touching of the first cylinder 410, which causes the first cylinder 410 to rotate. At the same time, there is a certain friction between the side wall of the second circular cavity and the side wall of the first cylinder 410, so that the first cylinder 410 will not rotate easily.

[0057] like Figures 1-2 As shown, in this embodiment, a mounting groove is provided on the upper end surface of the mounting plate 120;

[0058] The lifting assembly includes a fixing rod 131 disposed on the fixing plate 130 and having one end extending into the mounting groove. The fixing rod 131 is slidably disposed. The mounting plate 120 is provided with a bolt 230 having one end penetrating the mounting plate 120 and threadedly inserted into the fixing plate 130 .

[0059] In this embodiment, by setting the mounting groove, the fixing rod 131 and the bolt 230, the fixing rod 131 is fixedly installed on the fixing plate 130. When the fixing rod 131 is raised and lowered in the mounting groove, the fixing rod 131 can drive the video conferencing terminal body on the fixing plate 130 to be raised and lowered. When the fixing rod 131 is raised and lowered to a suitable height, the bolt 230 penetrates the mounting plate 120 and is threadedly inserted into the fixing plate 130, so that the position of the fixing rod 131 can be positioned, so that the video conferencing terminal body on the fixing plate 130 can always maintain the height after the lifting and lowering.

[0060] Working principle: the first cylinder 410 is rotated by the protrusion 430 to release the limit on the driving plate 340. Then, the driving rod 390 is pulled by the handle 220, so that the driving rod 390 drives the driving plate 340 to move up and release the squeezing of the slider 320. The second spring 370 drives one end of the insertion rod 310 to slide out of the socket 111 to release the fixation of the box body 200. At this time, the moving box body makes the positioning block 121 disengage from the positioning groove 112, and the box body 200 is moved to the corresponding positioning groove 112. After the positioning block 121 is stuck in the positioning groove 112, the insertion rod 310 is inserted into the corresponding socket 111 through the driving assembly to complete the height adjustment of the display screen on the mounting plate 120. When the height adjustment is completed, the first cylinder 410 is driven to rotate by the protrusion 430 so that the limiting block 500 in the limiting groove 412 is located in the groove 413, and the position of the driving plate 340 can be limited.
