DETAILED DESCRIPTION
[0029] The above and other technical contents, features and functions of the present invention are described in detail below with reference to the attached Figures 1 to 4 The details of the embodiments will be clearly presented. The contents mentioned in the following embodiments are all based on the drawings in the specification.
[0030] Various exemplary embodiments of the present utility model will be described below with reference to the accompanying drawings.
[0031] The utility model is an adjustable display screen base, which is mainly used for display screens of current office desktop computers, and comprises a bottom shell 1, which is made of metal or hard plastic, has a length of 50-80cm, a width of 25-40cm, a height of 3cm-10cm, and an adjustable height of 0-40cm. The bottom shell 1 is hollow with an opening at the upper end, a screw rod 2 is installed in the bottom shell 1 for horizontal rotation, and a bearing seat 25 is fixed at the intersection of the screw rod 2 and the bottom shell 1.
[0032] External threads 3 with opposite threads are provided on both sides of the screw 2, and each external thread 3 is threadedly connected to a slider 4 that slides laterally on the screw 2. A slide rail 23 for the slider 4 to slide is provided on the bottom shell 1, so that when the screw 2 rotates, the slider 4 can move closer or farther away from the screw 2 synchronously.
[0033] Each slider 4 is connected with a connecting rod 5 on both sides, with a total of four connecting rods 5 to ensure the stability of the connecting rod 5. The other end of the connecting rod 5 is connected with a placement plate 6. The placement plate 6 is placed above the bottom shell 1 and can contact the bottom shell 1 to cover the bottom shell 1. Two bases 24 are symmetrically installed at the lower end of the placement plate 6. The base 24 is hinged to the connecting rod 5, so that when the slider 4 moves, it drives the connecting rod 5 to support the placement plate 6 to rise or fall.
[0034] An upper mounting groove 9 is provided on the lower end surface of the placement plate 6, and an upper and lower mounting groove 8 is provided on the upper end surface of the bottom shell 1. A folding curtain 10 is fixedly installed between the upper mounting groove 9 and the lower mounting groove 8. The folding curtain 10 matches the shape of the bottom shell 1 and is a rectangular frame. The folding curtain 10 is made of plastic, leather, etc. with a certain hardness, so that when the placement plate 6 rises, the folding curtain 10 is driven to unfold, and the screw rod 2, slider 4, connecting rod 5 and other mechanisms inside the bottom shell 1 are shielded to ensure the beauty of the overall appearance and provide a certain degree of safety. When the placement plate 6 descends, the folding curtain 10 is driven to fold and compress, and the folding curtain 10 is detachably installed.
[0035] One end of the screw rod 2 passes through the bottom shell 1 and is fixedly connected to a rotating wheel 7. The side surface of the rotating wheel 7 is provided with friction patterns to increase friction and facilitate rotation.
[0036] The placement plate 6 can be raised and lowered by rotating the screw rod 2, thereby achieving height adjustment. At the same time, the screw connection prevents the placement plate 6 from falling when the screw rod 2 is not rotated, thus achieving self-locking. The weight of the display screen is not enough to damage the external thread, so the simplest operation and the most practical effect can be achieved at a low cost. Moreover, the use of the external thread 3 connection can also make the height adjustment range of the placement plate 6 not very large each time it is rotated for adjustment, thus meeting the effect that most people like. If you are not so concerned about the height adjustment range, you can choose the external thread 3 with a larger spacing.
[0037] In order to ensure the stability of the display screen, a first steering plate 11 is rotatably connected to the rear side of the bottom shell 1, the other end of the first steering plate 11 is rotatably connected to the second steering plate 12, the other end of the second steering plate 12 is rotatably connected to the third steering plate 13, and two clamping plates 14 are symmetrically installed on the other end of the third steering plate 13. The first steering plate 11, the second steering plate 12, the third steering plate 13 and the clamping plate 14 can achieve multi-degree-of-freedom adjustment, which is convenient for the clamping plate 14 to fix the display bracket, which refers to the bracket of the existing display screen, so as to ensure that the display screen can be placed more stably on the placement plate 6, and the adjustment of multiple degrees of automation can also make the clamping plate 14 clamped at any position of the display screen bracket.
[0038] Since the current display brackets are cylindrical and rectangular, in order to adapt to the shapes of most brackets, each card plate 14 is arc-shaped, and a transverse axis 15 is fixed to the lower end of the card plate 14. Two symmetrical sliding holes 16 are opened at the front end of the third steering plate 13, and the sliding holes 16 match the transverse axis 15. The transverse axis 15 is slidably installed in the sliding holes 16. A spring 17 is sleeved on the transverse axis 16, and the other end of the spring 17 is fixed to the bottom of the sliding hole 16. A retaining ring is fixed on the transverse axis 16, which can not only squeeze the spring 17, but also prevent the transverse axis 15 from disengaging from the sliding hole 16. The transverse axis 15 can rotate and move laterally in the sliding hole 16.
[0039] In order to further achieve the clamping of the bracket by the clamping plate 14 , a friction pad 19 is removably fixed on the inner side of the clamping plate 14 .
[0040] In the initial position, the spring 17 is in a free state, and the two clamps 14 are closest to each other. When clamping, the two clamps 14 are compressed away, the transverse shaft 15 compresses the spring 17, and then the clamps 14 clamp the bracket. The two springs 17 press against the clamps 14 to clamp the bracket. A threaded hole is provided on the outermost side of each clamp 14. Pass the locking bolt 18 through the two threaded holes and tighten it manually.
[0041] The arc of the card plate 14 is relatively wide. The arc card plate 14 can clamp both a circle and a rectangle, and does not need to perfectly match the arc. With the cooperation of the spring 17, the friction pad 19, the card plate 14, the placement plate 6, and the first steering plate 11, the second steering plate 12, and the third steering plate 13, the display can be more stably fixed.
[0042] The rotation of the first steering plate 11, the second steering plate 12, the third steering plate 13 and the card plate 14 has friction, and manual force is required to rotate them. They do not rotate in the self-use state to ensure their respective stability. At the same time, in order to further improve the stability, fixing screws 20 are rotatably installed on the first steering plate 11, the second steering plate 12, the third steering plate 13 and the card plate 14. When the positions are adjusted, the fixing screws 20 can be rotated to tighten the freedom.
[0043] In order to enrich the functions of the utility model, a matching placement box 21 is movably disassembled and plugged into the front end surface of the bottom shell 1. A plurality of placement slots 22 are provided in the placement box 21 for placing commonly used small office supplies such as paper clips, labels, staples, tapes, sticky notes, knives, erasers, etc.
[0044] Two symmetrically arranged plugging holes are fixed on the front outer end surface of the bottom shell 1, and two L-shaped plugging blocks matching the plugging holes are fixed on the rear of the placement box 21. The plugging blocks can be inserted into the plugging holes downwards and taken out upwards.
[0045] In order to further ensure the stability of the bottom shell 1, four transparent suction cups are symmetrically installed at the lower end of the bottom shell 1, which can be adsorbed on the office desk.
[0046] Working principle:
[0047] Insert the placement box 21 into the front side of the bottom shell 1 to place commonly used small office supplies, place the display with the bracket on the placement plate 6, adjust the freedom angles of the first steering plate 11, the second steering plate 12, the third steering plate 13, and the card plate 14, then clamp the bracket of the display with the card plate 14, lock the two card plates 14 with the locking bolts 18, and then tighten the first steering plate 11, the second steering plate 12, the third steering plate 13, and the card plate 14 with the fixing screws 20, and finally rotate the wheel 7 according to your needs, thereby driving the screw rod 2 to rotate, the screw rod 2 drives the slider 4 to move, and the slider 4 drives the connecting rod 5 to make the placement plate 6 rise and fall for height adjustment.
[0048] The utility model has the following technical effects.
[0049] 1. The utility model rotates the screw rod, which drives two symmetrical sliders on the screw rod to move closer or farther away, and the screw rod drives the placement plate to rise or fall at the same time, so as to adjust the height of the display screen, and the operation is simple and convenient.
