Detailed Implementation

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] Please see Figure 1-4 This embodiment provides a technical solution: a monitor stand, including a lower bracket 1 and a self-locking component 9;

[0023] Lower bracket 1: Its lower end is equipped with a pivot 2. Support bar 1 (3) and support bar 2 (4) are rotatably connected to the lower end of the outer arc surface of pivot 2. Support bar 2 (4) is located below support bar 3. The support feet at the lower ends of support bar 3 and support bar 2 (4) contact the desktop. The pivot 2 provides support for lower bracket 1, allowing support bar 3 and support bar 2 (4) to rotate around pivot 2, thereby adjusting the position of the support feet. Upper bracket 5 is slidably connected to the upper end of lower bracket 1. The upper end of upper bracket 5 is movably inserted into the mounting hole at the lower end of the monitor housing, and then fixed with screws passing through the round hole at the upper end of upper bracket 5. Rotary shaft 6 is rotatably connected to the lower end of upper bracket 5. A handwheel 10 is located at the front end of rotary shaft 6, and the rear end of rotary shaft 6 passes through... The lower bracket 1 has a long sliding groove in the middle and a gear 7 at its end. A rack 8 is located on the rear side of the lower bracket 1. The gear 7 meshes with the rack 8, allowing a handwheel 10 to rotate. The handwheel 10 drives the gear 7 to rotate clockwise via a rotating shaft 6. The gear 7 meshes with the stationary rack 8, and the gear 7, via the rotating shaft 6, drives the upper bracket 5 upwards. A protective shell 11 is located at the rear end of the upper bracket 5. A rectangular slide bar 12 is located inside the rear end of the protective shell 11. Both the protective shell 11 and the rectangular slide bar 12 are slidably connected to the lower bracket 1, providing sliding guidance for the upper bracket 5. The protective shell 11 also provides protection for internal components. The gear 7 and rack 8 are both located inside the protective shell 11. A retaining ring 17 is movably sleeved at the lower end of the outer arc surface of shaft 2. A spring plate 18 is provided at the lower end of shaft 2. The spring plate 18 is configured to cooperate with the retaining ring 17. The retaining ring 17 is located below the second support bar 4. The spring plate 18 provides upward pressure to the retaining ring 17. The retaining ring 17 squeezes the first support bar 3 and the second support bar 4, increasing the friction of rotation of the first support bar 3 and the second support bar 4, and preventing the display from rotating during use. An arc-shaped bar 13 is provided at the left rear end of the second support bar 4. A positioning shaft 14 is slidably connected to the middle of the first support bar 3. The lower end of the positioning shaft 14 is movably inserted into the vertically corresponding insertion hole on the upper surface of the arc-shaped bar 13. The upper end of the positioning shaft 14 is rotatably connected to a rocker 15 through a pin. A support is provided in the middle of the lower surface of the rocker 15. A support protrusion is provided, and a tension spring 16 is provided between the pin and the support bar 3. Pressing the rocker 15, the rocker 15 has a support protrusion on the left and right sides in the middle, driving the right end of the rocker 15 to lift up. The rocker 15 drives the positioning shaft 14 to move upward. The positioning shaft 14 moves upward and separates from the arc bar 13 and stretches the tension spring 16, thereby changing the included angle between the support bar 3 and the support bar 4. This can further adjust the support point of the monitor and ensure the convenience of placing the monitor. After the included angle between the support bar 3 and the support bar 4 is adjusted, the positioning shaft 14 is aligned with the insertion hole on the upper surface of the arc bar 13. The rocker 15 is released, and the tension spring 16 drives the positioning shaft 14 to be inserted into the arc bar 13, locking the included angle between the support bar 3 and the support bar 4.

[0024] Self-locking component 9: Used to automatically limit the counterclockwise rotation of the rotating shaft 6. Self-locking component 9 includes a ratchet 91, a ratchet tooth 92, a spring 93, and a positioning seat 94. The ratchet 91 is located at the front end of the outer arc surface of the rotating shaft 6. The ratchet tooth 92 is slidably connected inside the mounting hole of the upper bracket 5, and the ratchet tooth 92 is movably engaged with the ratchet 91. The spring 93 is installed in the middle of the mounting hole, and the positioning seat 94 is located at the end of the mounting hole away from the ratchet tooth 92. The spring 93 is located between the ratchet tooth 92 and the positioning seat 94, and the positioning seat 94 provides positioning for the spring 93. When the rotating shaft 6 drives the ratchet 91 to rotate clockwise, it will push the ratchet tooth 92 outwards and compress the spring 93. 3. When stopped, the spring 93 pushes the ratchet 92 to slide to the left and engage in the ratchet groove of the ratchet 91, thereby restricting the downward movement of the upper bracket 5. The self-locking assembly 9 also includes a pull seat 95, which is located on the left side of the ratchet 92. The right end of the pull seat 95 has a cylindrical end that passes through the spring 93 and the positioning seat 94. The left end of the pull seat 95 extends out of the left side of the upper bracket 5. When the display needs to be adjusted downward, the pull seat 95 can be pulled to the left. The pull seat 95 causes the ratchet 92 to separate from the ratchet 91, and the rotating shaft 6 can rotate counterclockwise. The display will move downward. When the pull seat 95 is released, the ratchet 92 extends to the right to self-lock.

[0025] The working principle of the monitor stand provided by this utility model is as follows: In use, the upper end of the upper bracket 5 is movably inserted into the mounting hole at the lower end of the monitor housing, and then fixed with screws passing through the round hole at the upper end of the upper bracket 5. During use, the support feet at the lower ends of support bar 3 and support bar 4 are in contact with the desktop, providing support for the lower bracket 1 through the pivot 2. At the same time, the position of the support feet can be adjusted according to the user's needs. During adjustment, support bar 3 and support bar 4 can be rotated around the pivot 2, thereby adjusting the position of the support feet. Positioning the rocker arm 15 allows for pressing down on the rocker arm 15. The rocker arm 15 has a support protrusion in the middle, which tilts the right end of the rocker arm 15 upwards. This causes the positioning shaft 14 to move upwards, separating it from the arc-shaped strip 13 and stretching the tension spring 16. This changes the angle between support strip 3 and support strip 4, further adjusting the monitor's support points and ensuring ease of placement. After adjusting the angle between support strip 3 and support strip 4, align the positioning shaft 14 with the insertion hole on the upper surface of the arc-shaped strip 13 and release the rocker arm. 15. The tension spring 16 drives the positioning shaft 14 to insert into the arc-shaped strip 13, locking the included angle between support strip 3 and support strip 4. At the same time, the spring plate 18 provides upward pressure to the retaining ring 17, which compresses support strip 3 and support strip 4, increasing the friction of their rotation and preventing the monitor from rotating during use. When the monitor is low, the handwheel 10 can be rotated. The handwheel 10 drives the gear 7 to rotate clockwise via the rotating shaft 6. The gear 7 meshes with the stationary rack 8, thus... The upper bracket 5 is moved upward by rotating shaft 6. When rotating shaft 6 drives ratchet 91 to rotate clockwise, it will push ratchet 92 outward to compress spring 93. When it stops, spring 93 pushes ratchet 92 to slide to the left and lock it into the ratchet groove of ratchet 91, which will restrict the downward movement of upper bracket 5. When it is necessary to adjust the monitor downward, pull seat 95 can be pulled to the left. Pull seat 95 drives ratchet 92 to separate from ratchet 91, and rotating shaft 6 can rotate counterclockwise. The monitor will move downward. Release pull seat 95, and ratchet 92 will extend to the right to lock itself.
