It should be noted that a sufficient gap is reserved between the movable plate 4 and the display base 7, the first slider 8 and the second slider 9 are respectively arranged on the two guide rails 6, and one end of the display base 7 Rotately connected with the first slider 8, the other end of the display base 7 is connected with the second slider 9 through an adjustment mechanism, specifically, the adjustment mechanism includes a box body 13, a rotating shaft 14 and a pull rod 15, and one end of the rotating shaft 14 is connected to the box body The side wall of 13 is rotationally connected, and the other end of rotating shaft 14 runs through the second slider 9 and is fixedly connected with the pull rod 15. Specifically, the side wall of the second slider 9 is fixedly connected with a limit block 20, and the limit block 20 is connected with The spring 21, the other end of the spring 21 is fixedly connected with the pull rod 15.
本实用新型中，14上固定连接有第一转轴17，14通过第一转轴17与盒体13转动连接，需要说明的是，盒体13内设有棘轮16和旋转臂17，棘轮16转动连接在盒体13的侧壁上，棘轮16的一侧与显示屏底座2的侧壁固定连接，旋转臂17的中部与转轴14固定连接，旋转臂17的两端分别转动连接有第一棘爪18和第二棘爪19，第一棘爪18和第二棘爪19与棘轮16相抵接触，第一滑块8和第二滑块9分别与连接杆5固定连接，螺纹杆3的另一端同轴连接有蜗轮10，螺纹杆3的一侧设有与蜗轮10互相啮合的蜗杆11，蜗杆11贯穿底座2的侧壁固定连接有摇柄12。In the utility model, 14 is fixedly connected with a first rotating shaft 17, and 14 is rotationally connected with the box body 13 through the first rotating shaft 17. It should be noted that the box body 13 is provided with a ratchet 16 and a rotating arm 17, and the ratchet 16 is rotationally connected. On the side wall of the box body 13, one side of the ratchet wheel 16 is fixedly connected to the side wall of the display base 2, the middle part of the rotating arm 17 is fixedly connected to the rotating shaft 14, and the two ends of the rotating arm 17 are respectively connected to the first ratchet in rotation. 18 and the second ratchet 19, the first ratchet 18 and the second ratchet 19 are in contact with the ratchet 16, the first slider 8 and the second slider 9 are fixedly connected with the connecting rod 5 respectively, the other end of the threaded rod 3 A worm wheel 10 is coaxially connected. One side of the threaded rod 3 is provided with a worm 11 intermeshing with the worm wheel 10 .
本实用新型中，使用时，首先将多媒体显示屏固定在显示屏底座7上，需要对多媒体显示屏进行升降时，转动摇柄12，摇柄12固定连接在蜗杆11上，蜗杆11与蜗轮10相互啮合，所以蜗轮10会发生转动，由于蜗轮10是同轴固定连接在螺纹杆3上的，所以螺纹杆3会发生转动，由于活动板4与螺纹杆3是转动连接的，所以，活动板4会随着摇柄12的转动上升或者下降，由于活动板4的两端分别通过连接杆5与第一滑块8和第二滑块9固定连接，所以第一滑块8和第二滑块9会发生移动，由于显示屏底座7是连接在第一滑块8和第二滑块9之间的，所以显示屏底座7回上升或者下降。In the utility model, when in use, the multimedia display screen is first fixed on the display screen base 7, and when the multimedia display screen needs to be lifted, the handle 12 is turned, and the handle 12 is fixedly connected to the worm 11, and the worm 11 and the worm wheel 10 Mesh with each other, so the worm wheel 10 will rotate. Since the worm wheel 10 is coaxially fixedly connected to the threaded rod 3, the threaded rod 3 will rotate. Since the movable plate 4 and the threaded rod 3 are rotatably connected, the movable plate 4 will rise or fall with the rotation of the rocking handle 12. Since the two ends of the movable plate 4 are fixedly connected with the first slider 8 and the second slider 9 through the connecting rod 5 respectively, the first slider 8 and the second slider Block 9 can move, because display screen base 7 is connected between the first slide block 8 and the second slide block 9, so display screen base 7 rises or falls back.
本实用新型中，需要调节多媒体显示屏的角度时，拉动拉杆15由于旋转臂17与拉杆15通过转轴14固定连接，所以旋转臂17会发生转动，由于第一棘爪18和第二棘爪19是转动连接在旋转臂17上的，所以第一棘爪18和第二棘爪19会随着拉杆15的来回摆动依次卡紧棘轮16并沿着棘轮16运动，由于在第二滑块9的侧壁上设有限位块20，并且套接有弹簧21，所以会限制第一棘爪18和第二棘爪19转动幅度不会过大而脱离棘轮16，由于棘轮16转动连接在盒体13的侧壁上，所以棘轮16会发生转动，由于棘轮16的一侧与显示屏底座7固定连接，所以显示屏底座7会随着拉杆15的来回摆动而进行旋转，达到调节角度的效果。In the utility model, when the angle of the multimedia display screen needs to be adjusted, pull the pull rod 15 because the rotating arm 17 is fixedly connected with the pull rod 15 through the rotating shaft 14, so the rotating arm 17 will rotate, because the first pawl 18 and the second pawl 19 It is rotatably connected to the rotating arm 17, so the first pawl 18 and the second pawl 19 will clamp the ratchet 16 sequentially and move along the ratchet 16 as the pull rod 15 swings back and forth, due to the movement of the second slider 9 The side wall is provided with a limit block 20, and is sleeved with a spring 21, so the rotation range of the first pawl 18 and the second pawl 19 will be limited so that they will not be disengaged from the ratchet 16, because the ratchet 16 is rotatably connected to the box body 13 On the side wall of the ratchet wheel 16, the ratchet wheel 16 can rotate. Because one side of the ratchet wheel 16 is fixedly connected with the display screen base 7, the display screen base 7 can rotate as the pull rod 15 swings back and forth to achieve the effect of adjusting the angle.
以上所述，仅为本实用新型较佳的具体实施方式，但本实用新型的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本实用新型揭露的技术范围内，根据本实用新型的技术方案及其实用新型构思加以等同替换或改变，都应涵盖在本实用新型的保护范围之内。The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto. The equivalent replacement or change of the new technical solution and the concept of the utility model shall be covered by the protection scope of the utility model.
