Description

Technical Field

[0001] The utility model relates to the technical field of display brackets, in particular to a screen adjustment device for a computer. Background Art

[0002] Computer monitors are one of the most important hardware components of a computer. Existing computer monitors are primarily supported by supports, which keep the screen at a certain height from the desktop for ease of use. With continued development, robotic arm supports are gradually replacing traditional monitor stands.

[0003] For example, the robotic arm joint structure and display bracket disclosed in announcement number CN220061262U install the entire device on the desktop through the base, which has the advantages of multi-angle adjustment and easy adjustment. However, the current robotic arm bracket has certain disadvantages during installation. The table top is clamped and fixed by the gasket pressure plate controlled by bolts, but the pressure range on the desktop is small. This results in a large pulling force on the smaller area of ​​the desktop when loading some larger monitors. Long-term use can easily cause damage to the desktop top. For this reason, we propose a screen adjustment device for a computer. Utility Model Content

[0023] The driven assembly 4 includes a cylinder 41, the bottom of which is rotatably mounted in the groove at the top of the contact plate 23, a spiral groove 42 is provided on the inner side of the cylinder 41, a fixing rod 43 is fixed in the groove at the top of the contact plate 23, the fixing rod 43 passes through the slide rod 44 and is slidably connected to the slide rod 44, a return spring 45 is fixed to the bottom of the slide rod 44, the bottom of the return spring 45 is fixed in the groove at the top of the contact plate 23, an insertion rod 46 is fixed on the surface of the slide rod 44, the insertion rod 46 is inserted in the spiral groove 42 on the inner side of the cylinder 41, a pull rope 47 is wound around and fixed on the surface of the cylinder 41, and the end of the pull rope 47 away from the cylinder 41 is close to the extension frame 33 One end of the interference spring 34 is fixed. When the entire device is installed, the socket 21 is placed on the top of the desktop, the interference plate 23 is at the bottom of the desktop, and the adjusting screw 25 is rotated to control the gasket 24 to push the interference plate 23 to move upward. The interference plate 23 gradually fits with the bottom of the desktop. During this process, the slide bar 44 is resisted by the bottom of the desktop and moves downward. The slide bar 44 carries the insertion rod 46 and slides downward along the spiral groove 42 on the inner side of the cylinder 41, causing the cylinder 41 to rotate. The cylinder 41 can release the pull rope 47, thereby no longer limiting the extension frame 33, and the extension frame 33 can extend out of the rotating frame 31 under the action of the interference spring 34.

[0024] The top of the contact plate 23 is provided with a limiting portion 5 for limiting the rotating frame 31. The limiting portion 5 includes a disc 51, which is fixed to the surface of the cylinder 41. The top of the disc 51 is provided with an arc groove 52. A moving rod 53 is inserted into the inner side of the arc groove 52. A cross bar 54 is fixed to the top of the moving rod 53. A vertical rod 55 is fixed to the end of the cross bar 54. The vertical rod 55 passes through the inner side of the groove at the top of the contact plate 23 and is slidably connected to the contact plate 23. The vertical rod 55 5 is fixed with a connecting spring 56, the end of the connecting spring 56 away from the vertical rod 55 is fixed in the groove at the top of the contact plate 23, the right side of the vertical rod 55 is hinged with a limit rod 57, one side of the vertical rod 55 is fixed with a fixing block 58, the other side of the vertical rod 55 is fixed with a spring piece 59, the end of the spring piece 59 away from the vertical rod 55 is fixed to the limit rod 57, under the action of the fixing block 58, the limit rod 57 can only move close to the spring piece 59 at the position of the hinge with the vertical rod 55. The limit rod 57 is used to limit the rotating frame 31 by contacting the side of the rotating frame 31 close to the rubber rope 38. When the cylinder 41 drives the disc 51 to rotate, the moving rod 53 and the horizontal rod 54 can only move left and right following the vertical rod 55. The disc 51 contacts the moving rod 53 through the arc groove 52 on the top of the disc 51, so that the moving rod 53 moves to the left with the horizontal rod 54 and the vertical rod 55, thereby controlling the limit rod 57 to no longer limit the rotating frame 31. 31 can swing under the action of the rubber rope 38. When the rotating frame 31 is manually controlled to reset, the rotating frame 31 can abut against the limit rod 57, so that the limit rod 57 swings toward the side close to the elastic piece 59 at the position hinged with the vertical rod 55. When the rotating frame 31 moves to a point where it no longer abuts against the limit rod 57, the limit rod 57 rotates and resets under the action of the elastic piece 59, and the rotating frame 31 is released. The rotating frame 31 can be abutted by the limit rod 57, thereby achieving reset.

[0025] It is worth noting that in this field, the robotic arm bracket 1 is an existing disclosed technology with mature existing products, and is not the main innovative part of this application, so its adjustment method is not specifically explained.

[0026] During installation, the socket 21 is placed on the top of the table, the contact plate 23 is at the bottom of the table, and the adjusting screw 25 is turned to control the gasket 24 to push the contact plate 23 upward, and the contact plate 23 gradually fits with the bottom of the table. During this process, the slide bar 44 is resisted by the bottom of the table and moves downward. The slide bar 44 brings the insertion rod 46 to slide downward along the spiral groove 42 on the inner side of the cylinder 41, causing the cylinder 41 to rotate, and the cylinder 41 can release the pull rope 47, so that the extension is no longer required. The frame 33 is limited, and the extension frame 33 can be extended out of the rotating frame 31 under the action of the resistance spring 34. At the same time, the cylinder 41 drives the disc 51 to rotate. Since the moving rod 53 and the horizontal rod 54 can only move left and right following the vertical rod 55, the disc 51 resists the moving rod 53 through the arc groove 52 opened on its top, so that the moving rod 53 moves to the left with the horizontal rod 54 and the vertical rod 55, thereby controlling the limit rod 57 to no longer limit the rotating frame 31, and the rotating frame 31 can swing under the action of the rubber rope 38.

[0027] The rotating frame 31 swings with the extension frame 33 at the position where the connecting rod 32 and the contact plate 23 are connected to the side away from the center of the contact plate 23, increasing the force-bearing area between the robotic arm bracket 1 and the desktop, effectively improving the stability of the installation, and avoiding the situation where the force-bearing area with the desktop is small, resulting in a large pulling force on the desktop, causing damage to the desktop. When the contact block 37 contacts the contact plate 23, the contact block 37 is pushed toward the inside of the extension frame 33, and the contact block 37 can contact the slide plate 35, pushing the slide plate 35 to move upward, and the slide plate 35 moves upward with the suction cup 36, and the suction cup 36 contacts the bottom of the desktop, so that the suction cup 36 is adsorbed on the bottom of the desktop, further improving the fixing effect, and effectively avoiding causing a large pulling force on the smaller area of ​​the desktop, causing damage to the desktop.

[0028] After the base 2 is installed on the desktop, the installation can be completed by simply sleeve-fitting the mechanical arm bracket 1 connected to the computer display screen onto the sleeve seat 21.

[0029] When disassembling, it is only necessary to turn the adjusting screw 25 to control the contact plate 23 to no longer contact the bottom of the desktop, and manually pull the extension frame 33 so that the suction cup 36 is no longer adsorbed on the bottom of the desktop. After the device is removed, the slide bar 44 is no longer in contact, and under the action of the return spring 45, the slide bar 44 moves upward, and the slide bar 44 and the insertion rod 46 slide upward along the spiral slide groove 42, causing the cylinder 41 to rotate in the opposite direction, and the cylinder 41 reels the pull rope 47 to pull the extension frame 33 back to its original position.

[0030] At the same time, the cylinder 41 drives the disc 51 to rotate, and the moving rod 53 drives the vertical rod 55 to reset through the horizontal rod 54. At this time, it is only necessary to manually control the rotation frame 31 to reset, and the rotation frame 31 can abut on the limit rod 57, so that the limit rod 57 swings to the side close to the spring piece 59 at the position where it is hinged with the vertical rod 55. When the rotation frame 31 moves to a point where it no longer abuts the limit rod 57, under the action of the spring piece 59, the limit rod 57 rotates and resets, and the rotation frame 31 is released, and the rotation frame 31 can be abutted by the limit rod 57, thereby achieving reset.

[0031] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
