Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments.
Referring to fig. 1-3, a computer display convenient to adjust comprises a base 1 and an installation block 2 with an upward concave cross section, the installation block 2 is welded with the upper surface of the base 1, a first installation cavity 3 and a second installation cavity 4 are arranged in the installation block 2, the first installation cavity 3 is arranged below the second installation cavity 4, the installation block 2 is connected with a rotating rod 5 in a penetrating and rotating mode through a bearing, one end, located in the second installation cavity 4, of the rotating rod 5 is in interference fit with a worm wheel 6, one end, located outside the installation block 2, of the rotating rod 5 is in rotational connection with the side wall of the groove of the installation block 2 through a bearing, the worm wheel 6 is meshed with a worm 7, the worm 7 is in interference fit with a driven shaft 8, the driven shaft 8 is in rotational connection with the installation block 2 through a bearing and extends into the first installation cavity 3, one end, located in the first installation cavity 3, of the driven shaft 8 is in interference fit with a fourth bevel gear 9, fourth bevel gear 9 meshes has third bevel gear 10, and third bevel gear 10 interference fit has axis of rotation 11, and one section interference fit that dwang 5 is located installation piece 2 recess has connecting block 14, and fixed surface is connected with screen 15 on the connecting block 14, is provided with high adjusting device in the first installation cavity 3.
Height adjusting device includes the first bevel gear 16 with axis of rotation 11 interference fit, first bevel gear 16 meshes there is second bevel gear 17, second bevel gear 17 interference fit has threaded rod 18, threaded rod 18 passes through the bearing with installation piece 2 and rotates the connection, threaded rod 18 is located the outside one section of installation piece 2 and is provided with the screw thread and with base 1 threaded connection, the rest is smooth structure, axis of rotation 11 and installation piece 2 run through sliding connection, through the meshing of first bevel gear 16 with second bevel gear 17, make threaded rod 18 rotate the height that can adjust screen 15.
The mounting block 2 is connected with a sliding block 12 in a penetrating and sliding mode, the section of the sliding block 12 is in an I shape, the I-shaped sliding block 12 limits the movement of the rotating shaft 11, when the rotating shaft 11 is pulled out and pushed to a limit position, good meshing of the first bevel gear 16, the second bevel gear 17, the third bevel gear 10 and the second bevel gear 9 can be guaranteed, the sliding block 12 and the rotating shaft 11 are connected in a penetrating and rotating mode through bearings, and a rotating wheel 13 is glued at one end, located outside the mounting block 2, of the rotating shaft 11.
The thread lead angle of the threaded rod 18 is smaller than the equivalent friction angle of a thread pair formed by the threaded rod 18 and the base 1, so that the threaded connection between the threaded rod 18 and the base 1 realizes self-locking, and the phenomenon that the stability of the screen 15 is influenced by shaking at the threaded connection part is avoided. The unfolding helical angle of the worm 7 is smaller than the contact friction angle between the worm 7 and the worm wheel 6, so that the worm 7 and the worm wheel 6 are meshed to realize self-locking, and the worm wheel 6 is prevented from driving the worm 7 to rotate.
The outer wall of the rotating wheel 13 is carved with anti-slip lines, the anti-slip lines on the outer wall of the rotating wheel 13 prevent slipping in the process of operating the rotating wheel 13, the lower surface of the base 1 is bonded with an anti-slip mat, the anti-slip mat on the lower surface of the base 1 prevents the display from slipping when external force is applied, and the stability of the display is improved.
In the utility model, if the pitch angle of the screen 15 needs to be adjusted, when the rotating wheel 13 is pushed to the point that the screen cannot be pushed, at this time, the third bevel gear 10 is meshed with the fourth bevel gear 9, the rotating wheel 13 is rotated, so that the rotating shaft 11 is rotated, the rotating shaft 11 drives the third bevel gear 10 in interference fit with the rotating wheel to rotate, so that the second bevel gear 9 meshed with the third bevel gear 10 is rotated, the second bevel gear 9 drives the driven shaft 8 in interference fit with the driven shaft to rotate, the driven shaft 8 drives the worm 7 in interference fit with the driven shaft to rotate, so that the worm wheel 6 meshed with the worm 7 rotates, the worm wheel 6 drives the rotating rod 5 in interference fit with the worm to rotate, the rotating rod 5 drives the connecting block 14 to rotate, and thus the pitch angle of the screen 15 is adjusted;
if the height of the screen 15 needs to be adjusted, when the rotating wheel 13 is pulled to be unable to be pulled, the rotating wheel 13 is rotated, so that the rotating shaft 11 rotates, at the moment, the first bevel gear 16 is meshed with the second bevel gear 17, the rotating shaft 11 drives the first bevel gear 16 in interference fit with the rotating shaft to rotate, so that the second bevel gear 17 meshed with the first bevel gear 16 rotates, the second bevel gear 17 drives the threaded rod 18 in interference fit with the threaded rod to rotate, and the threaded rod 18 is gradually screwed out of the base 1 through threaded connection with the base 1, so that the height of the screen 15 is changed.
The above, only be the concrete implementation of the preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, the concept of which is equivalent to replace or change, should be covered within the protection scope of the present invention.
