Description

Technical Field

[0001] This utility model relates to the field of display technology, specifically to a display stand. Background Technology

[0002] As an output device, the monitor plays a crucial role in modern information interaction. It converts electronic signals into visual images or text, presenting various types of information to users. From a technical perspective, common monitors are mainly divided into liquid crystal displays (LCDs) and organic light-emitting diode (OLED) displays. LCDs use liquid crystal molecules to control the backlight to display images. By changing the arrangement of liquid crystal molecules, the light transmittance is altered, thus presenting pixels with different brightness and colors, which combine to form a complete picture. OLEDs, on the other hand, are based on the characteristic of organic materials emitting light under the influence of an electric field. Each pixel can independently control its light emission, offering advantages such as fast response speed, high contrast, and wide viewing angles, providing more vivid and realistic image display effects. In modern office and life scenarios, monitors have become indispensable devices, and a high-quality monitor stand is crucial for improving user experience and ensuring stable monitor use.

[0003] Currently, some monitor stands have a fixed height, which cannot meet the needs of different users. At the same time, fixed height stands limit the compatibility of monitors with other office equipment, such as file racks or drawing tablets of a specific height, thus affecting the rationality and functionality of the overall office layout. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a monitor stand with adjustable height and positioning, which solves the problem that the fixed height of the stand affects its functionality in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A display stand includes a base with feet mounted on its bottom and a fixed seat connected to the top of the base. The surface of the fixed seat is provided with a spacing adjustment mechanism, and a lifting and positioning mechanism is provided above the spacing adjustment mechanism. The lifting and positioning mechanism includes a lifting device and a positioning device, and the positioning device positions and fixes the height adjusted by the lifting device.

[0007] Preferably, the lifting device includes a fixed rod, a lifting groove, a handle, a rotating shaft, a lead screw, and a lifting block. A fixed rod is provided above the spacing adjustment mechanism. A lifting groove is formed on the surface of the fixed rod. A handle is connected to the top of the fixed rod. A rotating shaft is connected to the bottom of the handle. A lead screw is connected to the bottom of the rotating shaft. A lifting block is connected to the surface of the lead screw. A positioning device is provided on the surface of the lifting block.

[0008] Preferably, the positioning device includes a positioning plate, a fixing hole, a spring, a pull block, a positioning rod, a positioning hole, and a display mounting base. The positioning plate is connected to the outer side of the lifting block. The fixing hole is formed on the surface of the positioning plate. The spring is connected to the outer side of the fixing hole. The pull block is connected to the outer end of the spring. The positioning rod is connected to the inner end of the pull block. The positioning hole is formed on the surface of the fixing rod. The display mounting base is connected to one side of the lifting block.

[0009] Preferably, the foot supports are provided in four identical sets at the bottom of the base, and are symmetrically distributed at the four corners of the bottom of the base with respect to the central axis of the base.

[0010] Preferably, the spacing adjustment mechanism includes an adjustment groove, a motor, a screw, a spacer, and an adjustment block. The surface of the fixed base is provided with an adjustment groove. One end of the fixed base is connected to a motor. The output end of the motor is connected to a screw. A spacer is provided in the middle part of the screw. An adjustment block is threadedly connected to the surface of the screw. A lifting device is provided above the adjustment block.

[0011] Preferably, the rotating shaft is configured to rotate by means of a handle and a lead screw, and the outer wall dimension of the lifting block matches the inner wall dimension of the lifting groove.

[0012] Preferably, the pull block and the positioning rod cooperate to form a telescopic structure, and multiple sets of positioning holes are equally spaced on the surface of the fixing rod.

[0013] Compared with the prior art, the present invention provides a monitor stand with the following advantages:

[0014] 1. This monitor base features a lifting device. When the monitor height needs adjustment, the operator turns the handle. Since the handle is connected to a rotating shaft, which in turn is connected to a lead screw, the lead screw rotates accordingly. The lead screw is threaded into the lifting block. Based on the lead screw transmission principle, the rotation of the lead screw drives the lifting block to move linearly along the axial direction. The lifting block is located within the lifting groove of the fixed rod. The lifting groove serves as a guide and limiter, ensuring smooth linear lifting and lowering, preventing wobbling or deviation. By controlling the direction of the handle's rotation, the direction of the lead screw's rotation can be precisely controlled, determining the up and down movement of the lifting block, thus achieving flexible adjustment of the monitor height. When the lifting block reaches the appropriate height, a positioning device fixes its position, ensuring the monitor remains stably at that height to meet usage requirements.

[0015] 2. This monitor base features a positioning device. When the monitor height needs adjustment, the user pulls the lever outwards, overcoming the spring force to pull the positioning rod out of the positioning hole. The positioning plate unlocks from the fixed rod, and the lifting block slides up and down along the fixed rod, thus changing the monitor mounting base and monitor height. Once the desired height is achieved, the user releases the lever, the stretched spring retracts, generating an inward pulling force that moves the lever and positioning rod inwards. If the positioning rod aligns with another positioning hole on the fixed rod, it will quickly insert, the positioning plate and fixed rod will reconnect tightly, the lifting block will lock at the new height, and the monitor will be stable in the adjusted position. The positioning device is ingeniously designed, allowing for convenient and quick adjustment and positioning of the monitor height, meeting the diverse needs of different users.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 A monitor stand includes a base 1, a foot support 2 installed at the bottom of the base 1, a fixed seat 3 connected to the top of the base 1, a spacing adjustment mechanism 4 provided on the surface of the fixed seat 3, and a lifting and positioning mechanism 5 provided above the spacing adjustment mechanism 4. The lifting and positioning mechanism 5 includes a lifting device and a positioning device.

[0022] In this embodiment, the lifting device includes a fixed rod 501, a lifting groove 502, a handle 503, a rotating shaft 504, a lead screw 505, and a lifting block 506. The fixed rod 501 is positioned above the spacing adjustment mechanism 4. The surface of the fixed rod 501 has a lifting groove 502. The top of the fixed rod 501 is connected to the handle 503, the bottom of the handle 503 is connected to the rotating shaft 504, and the bottom of the rotating shaft 504 is connected to the lead screw 505. The surface of the lead screw 505 is connected to the lifting block 506, and the surface of the lifting block 506 is equipped with a positioning device. With this lifting device, when the height of the display needs to be adjusted, the operator manually rotates the handle 503. Since the bottom of the handle 503 is connected to the rotating shaft 504, the rotation of the handle 503 will cause the rotating shaft 504 to rotate synchronously. The bottom of the rotating shaft 504 is connected to the lead screw 505, so the lead screw 505 will begin to rotate along with the rotating shaft 504. The surface of the lead screw 505 is connected to the lifting block 506. Furthermore, there is a threaded engagement between the lead screw 505 and the lifting block 506. According to the principle of lead screw transmission, when the lead screw 505 rotates, the lifting block 506, which is engaged with it, will move linearly along the axial direction of the lead screw 505 under the drive of the lead screw 505. At the same time, the lifting block 506 is located in the lifting groove 502 opened on the surface of the fixed rod 501. The lifting groove 502 plays a guiding and limiting role for the lifting block 506, ensuring that the lifting block 506 can only make smooth linear lifting and lowering movements within the path defined by the lifting groove 502, avoiding swaying or deviation. By controlling the rotation direction of the control handle 503, the rotation direction of the lead screw 505 can be precisely controlled, thereby determining whether the lifting block 506 moves up or down, thus realizing flexible adjustment of the display height. When the lifting block 506 moves to the appropriate height, its position is fixed by the positioning device, so that the display is stably maintained at that height for use.

[0023] Furthermore, the positioning device includes a positioning plate 507, a fixing hole 508, a spring 509, a pull block 510, a positioning rod 511, a positioning hole 512, and a display mounting base 513. The positioning plate 507 is connected to the outer side of the lifting block 506. The fixing hole 508 is formed on the surface of the positioning plate 507. The spring 509 is connected to the outer side of the fixing hole 508. The pull block 510 is connected to the outer end of the spring 509. The positioning rod 511 is connected to the inner end of the pull block 510. The positioning hole 512 is formed on the surface of the fixing rod 501. One side of the lifting block 506 is connected to the monitor mounting base 513. Through the positioning device, when the monitor height needs to be adjusted, the user first grasps the pull block 510 and pulls it outwards. Under the user's pulling force, the pull block 510 overcomes the elastic force of the spring 509, causing the positioning rod 511 to be pulled out of the positioning hole 512. As the positioning rod 511 completely disengages from the positioning hole 512, the locking relationship between the positioning plate 507 and the fixed rod 501 is released, and the lifting block 506 gains the freedom to move up and down along the fixed rod 501. Users can slide the lifting block 506 up or down along the fixed rod 501 according to their needs, thereby changing the height of the monitor mounting base 513 and the monitor. When the monitor is adjusted to a suitable height, the user releases the pull block 510. At this time, the spring 509, which was originally stretched, begins to contract due to the elastic restoring force and generates an inward pulling force. This pulling force drives the pull block 510 and the positioning rod 511 connected to it to move inward. If the positioning rod 511 is aligned with another positioning hole 512 on the surface of the fixed rod 501, the positioning rod 511 will quickly insert into the positioning hole 512 under the pulling force of the spring 509. In this way, the positioning plate 507 is tightly connected to the fixed rod 501 again, and the lifting block 506 is relocked to the new height position. The monitor is also stabilized at the adjusted height, providing users with a stable user experience. Through this ingenious design and working method of the positioning device, the height adjustment and positioning of the monitor can be achieved conveniently and quickly, meeting the diverse needs of different users for monitor height in different scenarios.

[0024] Furthermore, four identical sets of feet 2 are installed at the bottom of the base 1, symmetrically distributed at the four corners of the bottom of the base 1 along the central axis of the base 1. The feet 2 provide stable and balanced support for the entire monitor base. The four symmetrically distributed feet can evenly bear the weight of the monitor and the base, effectively distributing gravity and ensuring that the base remains stable on various flat surfaces, preventing tipping due to a shift in the center of gravity. The bottom of the feet is usually made of non-slip material to increase friction with the surface on which it is placed. Even on smooth desktops or in environments with slight vibrations, the base can be firmly fixed, creating good conditions for the stable operation of the monitor and ensuring that the user's viewing experience is not affected by the shaking of the base.

[0025] Furthermore, the spacing adjustment mechanism 4 includes an adjustment groove 401, a motor 402, a screw 403, a spacer 404, and an adjustment block 405. The surface of the fixed base 3 has an adjustment groove 401. One end of the fixed base 3 is connected to the motor 402, and the output end of the motor 402 is connected to the screw 403. A spacer 404 is provided in the middle part of the screw 403, and the adjustment block 405 is threaded onto the surface of the screw 403. A lifting device is provided above the adjustment block 405. Through the arrangement of the spacing adjustment mechanism 4, precise adjustment of the horizontal position of the lifting device is achieved. When motor 402 starts, its output drives screw 403 to rotate. Since screw 403 is threadedly connected to adjusting block 405, adjusting block 405 will move linearly along adjusting groove 401 under the rotation of screw 403. Spacer 404 plays a positioning role to ensure the stability and accuracy of the movement of adjusting block 405. By controlling the forward and reverse rotation and the number of rotations of motor 402, the position of adjusting block 405 in adjusting groove 401 can be flexibly changed, thereby adjusting the horizontal distance between lifting device and display to adapt to the needs of display position in different usage scenarios.

[0026] In addition, the rotating shaft 504, through the cooperation of the handle 503 and the lead screw 505, forms a rotating structure. The outer wall size of the lifting block 506 matches the inner wall size of the lifting groove 502. Through the setting of the lifting groove 502, the lead screw 505 and the lifting block 506, the height of the monitor can be conveniently adjusted. When the user turns the handle 503, the rotating shaft 504 rotates, which in turn causes the lead screw 505 to rotate synchronously. Because the lifting block 506 is threadedly connected to the lead screw 505, and the outer wall of the lifting block 506 is tightly fitted to the inner wall of the lifting groove 502, the lifting groove 502 provides a guiding function for the lifting block 506, preventing it from deviating or rotating when the lead screw 505 rotates. Therefore, the rotation of the lead screw 505 is converted into the vertical linear movement of the lifting block 506 along the lifting groove 502, thereby driving the monitor mounting base 513 connected to the lifting block 506 and the monitor to achieve height adjustment, meeting the viewing needs of users of different heights.

[0027] It is worth noting that the pull block 510, through the cooperation of the spring 509 and the positioning rod 511, forms a telescopic structure. Multiple sets of positioning holes 512 are evenly spaced on the surface of the fixed rod 501. Through the arrangement of the spring 509 and the positioning holes 512, the precise positioning and locking of the height position of the lifting block 506 is achieved. When the pull block 510 is pulled, the positioning rod 511 retracts against the elastic force of the spring 509, releasing the lock on the fixed rod 501. At this time, the lifting block 506 can move along the fixed rod 501. When the lifting block 506 reaches the appropriate height, the pull block 510 is released, and the elastic restoring force of the spring 509 pushes the positioning rod 511 to insert into the corresponding positioning hole 512 on the surface of the fixed rod 501. The evenly spaced positioning holes 512 can meet different height adjustment needs, ensuring that the lifting block 506 can be stably positioned at any height, providing reliable support for the monitor and preventing the monitor from moving or shaking accidentally due to the height not being locked.

[0028] When in use, after the monitor is mounted on the monitor mounting base 513 of the base, the four sets of feet 2 symmetrically distributed around the central axis at the bottom of the base 1 come into play. They evenly bear the weight of the monitor and the entire base, distributing the gravity to the placement surface and ensuring that the entire device remains stable on various surfaces. The anti-slip material on the bottom of the feet 2 increases the friction with the placement surface, further preventing the device from sliding or tipping over due to slight vibrations or external contact, laying the foundation for subsequent adjustment operations and stable use of the monitor. If the user needs to adjust the horizontal position of the monitor, the motor 402 in the spacing adjustment mechanism 4 can be activated. The output end of the motor 402 drives the screw 403 to rotate. Since the screw 403 is threadedly connected to the adjustment block 405, the adjustment... The segment 405 moves linearly along the adjustment groove 401 on the surface of the fixed base 3 under the rotation of the screw 403. The spacer 404 located in the middle of the screw 403 ensures the stability and accuracy of the movement of the adjustment block 405. By controlling the forward and reverse rotation and the number of rotations of the motor 402, the user can precisely change the position of the adjustment block 405 in the adjustment groove 401, thereby driving the lifting device above the adjustment block 405 and the display mounted on it to adjust the horizontal position to adapt to different usage scenarios and layout requirements. When the height of the display needs to be adjusted, first operate the positioning device. The user holds the pull block 510 and pulls it outward. The pull block 510 overcomes the elastic force of the spring 509 and drives the positioning rod 511 from the fixed rod. The lifting block 506 is pulled out of the positioning hole 512 on the surface of the fixed rod 501. At this time, the locking relationship between the positioning plate 507 and the fixed rod 501 is released, and the lifting block 506 gains the freedom to move up and down along the fixed rod 501. Then, the user manually turns the handle 503, which drives the connected rotating shaft 504 to rotate synchronously. The rotating shaft 504 then drives the lead screw 505 to rotate. Since the lead screw 505 is threadedly connected to the lifting block 506, and the lifting block 506 is located in the lifting groove 502 on the surface of the fixed rod 501, the lifting groove 502 provides guidance and limit for the lifting block 506. The rotation of the lead screw 505 will cause the lifting block 506 to make a smooth linear lifting motion in the lifting groove 502 along the axial direction of the lead screw 505. The user controls the rotation of the handle 503. The direction of movement allows for precise control of the rotation direction of the lead screw 505, thus determining whether the lifting block 506 moves upward or downward, enabling flexible adjustment of the monitor height. Once the monitor is adjusted to the appropriate height, the user releases the pull block 510. The previously stretched spring 509 contracts due to its elastic restoring force, generating an inward pulling force that moves the pull block 510 and the positioning rod 511 inward. If the positioning rod 511 aligns with another positioning hole 512 on the surface of the fixed rod 501, the positioning rod 511 will quickly insert into the positioning hole 512 under the pulling force of the spring 509, causing the positioning plate 507 to reconnect tightly with the fixed rod 501. The lifting block 506 is then relocked at the new height position, and the monitor stabilizes at the adjusted height.This provides users with a stable viewing experience. Ultimately, the entire monitor's height can be adjusted quickly and easily.
