Description

Technical Field

[0001] This invention relates to the field of monitor stand technology, specifically a monitor stand. Background Technology

[0002] A monitor stand is a product used to secure monitors, laptops, or tablets. It helps solve various technical challenges people encounter when using computers at home or in business offices. Its ergonomic design can prevent health problems caused by work fatigue, improve work efficiency, and create an ideal work-life balance. Monitor stands are widely used in retail, entertainment, finance, healthcare, and transportation sectors.

[0003] Currently, most monitor stands on the market use bolts to secure the connection between the stand and the monitor. This design requires that mounting holes be pre-drilled on the back of the monitor, and that the stand's interface size match the monitor's hole spacing. Therefore, the stand's applicability is limited by the position of the monitor's mounting holes, making it difficult to adapt to products of different specifications and resulting in poor versatility. When users replace their monitors, they often need to purchase a new stand to match the mounting holes of the new device, which not only increases usage costs but also leads to the idleness and waste of the original stand resources. Summary of the Invention

[0004] The purpose of this invention is to provide a monitor stand to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A monitor stand includes an adjustment arm one, an adjustment arm two, a base, and a fixing frame;

[0014] Two connecting frames 1 and two connecting frames 2 enclose a rectangle, and two sides of the two connecting frames 2 are inserted into two sides of the connecting frame 1, so that the rectangle can be expanded or reduced.

[0015] Furthermore, both the first and second telescopic rods, which are arranged longitudinally, include a sliding part and a telescopic rod body, wherein the telescopic rod body is inclined relative to the sliding part.

[0016] Furthermore, the telescopic rod one and the telescopic rod two have the same structure, including a telescopic rod body and a sliding part. The telescopic rod body and the sliding part are rotatably connected, so that adjacent telescopic rod one and telescopic rod two can be used in combination.

[0017] Furthermore, a limiting groove is provided at the movable strip hole.

[0018] Furthermore, a crossbeam is snapped between the first connecting rod and the second connecting rod located above, and a support bar is provided on the crossbeam, with a lighting component connected to the end of the support bar.

[0019] Furthermore, the installation components one and two have the same structure, both including a movable part and a telescopic rod three. The movable part is provided with a slot and is inserted into the fixed base through the slot. The slot is provided with a limiting pin, which passes through the movable strip hole to connect the movable part with the movable strip hole and allow the movable part to slide and rotate relative to the movable strip hole. One end of the telescopic rod three is connected to the movable part, and the other end is provided with a mounting part three for connecting with the mounting hole.

[0020] Furthermore, two adjacent telescopic rods can be used together to stack the two mounting parts to form a whole.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0038] Please refer to Figure 1-9 ;

[0039] The bracket described in this invention has two adjustable joints, providing users with a wider adjustment range, more precise positioning options, and greater user comfort. Specifically, the bracket includes an adjusting arm 1, an adjusting arm 2, a base 3, and a fixing frame 4. The adjusting arm 1 is connected to the adjusting arm 2 via a fixing adjustment mechanism 5, used to adjust the angle between the two and for fixing. The adjusting arm 2 is connected to the base 3 via a fixing adjustment mechanism 6, used to adjust the angle between the two and for fixing. This dual-joint structure design enhances user flexibility and comfort during use.

[0040] The fixed adjustment mechanism 5 includes a rotating shaft 52, which is rotatably connected to the adjustment arm 2. The rotating shaft 52 is fixedly connected to the bottom of the adjustment arm 1, allowing the adjustment arm 1 to rotate around the rotating shaft 52. The rotating shaft 52 extends through both ends of the adjustment arm 2 and has a fixing structure located outside the adjustment arm 2. The fixing structure includes a rhythm piece 55 disposed at the end of the rotating shaft 52. The end face of the adjustment arm 2 has a plurality of arc-shaped slots 21 arranged in a ring. The ends of the rhythm pieces 55 spring arms engage with the arc-shaped slots 21. The more arc-shaped slots 21 there are, the more precise the adjustable angle is. Preferably, there are six arc-shaped slots 21 in this application. Therefore, there are also six spring arms. When the adjustment arm 1 rotates, the rotating shaft 52 rotates accordingly. At the same time, the ends of the six spring arms simultaneously disengage from the arc-shaped slots 21. After rotating a certain angle, it automatically engages with the next arc-shaped slot 21 and is fixed in place. This structure only plays an auxiliary role; the main balance is achieved by the engagement of several spring arms and the arc-shaped slots 21. Each spring arm and arc-shaped slot 21 forms a fixed point, requiring external force to break this balance. Therefore, even when the adjusting arm 1 is tilted, balance can be maintained. Furthermore, the rotating shaft 52 is also fixed with a metal spring 56, located outside the rhythm plate 55. The spring arm 2 of the metal spring 56 abuts against the spring arm 1 of the rhythm plate 55. Normally, the spring arm 1 is made of plastic, which will fatigue after repeated rotations, leading to irreversible deformation. Therefore, the metal spring 56 is added to assist in constantly applying external force to the spring arm 1 to reset it. Additionally, since the fixed adjustment mechanism 2 6 has the same structure and effect as the fixed adjustment mechanism 1 5, it will not be described in detail here.

[0041] The mounting bracket 4 is mounted on the adjusting arm 1 and is used to fix the monitor body 7. The mounting bracket 4 includes a mounting base 41. The mounting base 41 has four diagonal holes 42. The positions of the four holes 42 correspond to the mounting holes of most conventional monitor bodies 7 on the market, so that users can directly install conventional monitor bodies 7.

[0042] In addition, the mounting base 41 also has an expansion function. It can be connected with the connecting components and the support frame to form a complete monitor body 7 mounting bracket, thereby adapting to other monitor models with different mounting hole positions. Specifically, mounting components 1 44 are arranged at two opposite corners, and mounting components 2 45 are arranged at the other two opposite corners. One end of mounting components 1 44 and mounting components 2 45 are connected to the corresponding movable strip hole 42. The other end of mounting components 1 44 and mounting components 2 45 is provided with a mounting part for connecting to the mounting hole of the monitor body 7. The middle part of mounting components 1 44 and mounting components 2 45 are both telescopic structures, so that the mounting part can extend to the monitor mounting hole at different positions, thereby adapting to various monitor body 7 models.

[0043] The mounting base 41 in this embodiment includes a connecting block and a fixing plate. Four movable slots 42 are set on the fixing plate. The shape of the fixing plate is not limited and can be a common shape such as a circle or a square. Regardless of the shape, it is only necessary to ensure that the four movable slots 42 are located at the four diagonal points of the fixing plate. A rotating shaft is rotatably connected to the connecting block. Both ends of the rotating shaft are fixedly connected to the fixing plate. At the same time, torsion springs are symmetrically arranged on both sides of the fixing plate. One end of the torsion spring is connected to the fixing plate and the other end is fixedly connected to the connecting block, so that the fixing plate can rotate, thereby supporting the forward or backward tilt adjustment of the display body 7 and improving the user experience.

[0044] In this embodiment, a lifting device can also be provided on the adjusting arm 1 to realize the lifting and adjusting function of the display body 7. The specific structure of the lifting device can be referred to in the prior art document "CN212251770U, a display lifting frame". The two ends of the constant force spring are connected to the lifting component and the column respectively. After the constant force spring is stretched, it tends to force the lifting component to move upward, thereby providing support force for the display and realizing the display can stop and start during the lifting process. The connecting block is connected to the lifting component. By controlling the rise or fall and the position fixation of the lifting component, the fixing frame 4 drives the display body 7 to adjust and position together, so as to meet the height adjustment needs of different users and usage scenarios.

[0045] Currently, whether it is a standard or non-standard monitor body 7, its mounting holes are usually located on the back of the monitor. The difference between the two lies in whether the position of the mounting holes is compatible with most brackets on the market. For non-standard monitors with different mounting hole positions, the structure of this invention is designed to be able to adjust the position to accommodate these different mounting hole positions, thereby achieving the fixation of the monitor and the mounting bracket 4. In addition, considering that the mounting part 71 on the back of the monitor can be flat or concave, this invention also provides two different installation methods to accommodate the two different structures of the mounting part 71.

[0046] Example 1:

[0047] When the mounting portion 71 of the display body 7 has a recessed structure, the mounting components are embedded in the recess. Specifically, mounting component one 44 includes an L-shaped connecting rod one 441. A reinforcing block 46 is provided at the corner of the connecting rod one 441 to strengthen the connection strength of the connecting rod and prevent it from breaking due to excessive weight. One end of the connecting rod one 441 is connected to the movable slot 42, and the other end is fixed with an L-shaped connecting bracket one 442. Telescopic rods one 443 are slidably connected to the two sides of the connecting bracket one 442. The ends of the two telescopic rods one 443 are provided with mounting parts one 444. The two mounting parts one 444 can be used individually or in combination. Mounting component two 45 includes an L-shaped connecting rod two 451. A reinforcing block 46 is provided at the corner. One end of the connecting rod 451 is connected to the movable strip hole 42, and the other end is fixed with an "L"-shaped connecting frame 452. Telescopic rods 453 are slidably connected to the two sides of the connecting frame 452. The ends of the two telescopic rods 453 are provided with mounting parts 454. The two mounting parts 454 can be used alone or in combination. The two connecting frames 442 are designed diagonally, and the two connecting frames 452 are also designed diagonally. The two sides of the connecting frame 442 are provided with slots. The two sides of the connecting frame 452 are inserted into the slots. Since the connecting frame 442 is provided with slots, the connecting frame 442 is relatively thin. Usually, the connecting frame 452 is inserted into the slots of the connecting frame 442 to fill its interior and achieve the effect of strengthening the structure.

[0048] Connector 1 442 and Connector 2 452 are not fixed except for their interlocking relationship. Therefore, when not installed, Mounting Component 1 44 and Mounting Component 2 45 can be separated from each other, which facilitates transportation and avoids deformation caused by vibration during transportation.

[0049] In use, mounting component 1 44 and mounting component 2 45 are not connected to the fixing plate. At this time, both components can move freely. After mounting component 1 44 and mounting component 2 45 are combined to form a rectangle, they are placed in the mounting part 71 of the monitor body 7. Since different monitors have different design specifications, the size of the groove in the mounting part 71 is also different. The size of the enclosing rectangle is adjusted by sliding connecting bracket 1 442 and connecting bracket 2 452 against each other, so that the edges of connecting bracket 442 and connecting bracket 2 452 abut against the inner wall of the mounting part 71. Then, the positions of telescopic rod 1 443 and telescopic rod 2 453 are adjusted according to the number and position of the mounting holes.

[0050] In one embodiment, if the display body 7 has eight or more mounting holes, one connecting bracket corresponds to one area of ​​mounting holes. By sliding the positions of the first telescopic rod 443 and the second telescopic rod 453, the first mounting part 444 and the second mounting part 454 are simultaneously extended or retracted to reach the position of the corresponding mounting hole, so as to realize the installation of the display body 7.

[0051] Implementation method two, refer to Figure 1 and Figure 4 Assuming there are four mounting holes, each corresponding to one of the four diagonal positions, and one connecting bracket corresponds to one area of ​​mounting holes, the telescopic rods 443 on both sides of the connecting bracket 442 slide toward the mounting hole position in their respective areas, and extend or retract to adjust the position of the mounting part 444, so that the two mounting parts 444 are combined together. The two mounting parts 444 are then connected to the mounting holes of the monitor body 7 by screws passing through them. Similarly, the telescopic rods 453 on both sides of the connecting bracket 452 slide toward the mounting hole position of the monitor body 7 in their respective areas, and extend or retract to adjust the position of the mounting part 454, so that the two mounting parts 454 are combined together. The two mounting parts 454 are then connected to the mounting holes of the monitor body 7 by screws passing through them.

[0052] In the two embodiments described above, if two telescopic rods 443 and 453 are arranged longitudinally, after installation, the longitudinally arranged telescopic rods 443 and 453 will not bear any force and cannot limit the transversely arranged telescopic rods 443 and 453. That is, the transversely arranged telescopic rods 443 and 453 can still slide longitudinally. In order to improve stability, both the longitudinally arranged telescopic rods 443 and 453 include a sliding part 47 and a telescopic rod body 48, and the telescopic rod body 48 is inclined relative to the sliding part 47.

[0053] In the third implementation method, since the position between connecting bracket 1 442 and connecting bracket 2 452 is not defined, there is a risk that connecting bracket 1 442 and connecting bracket 2 452 may slide against each other. If there are four mounting holes, and telescopic rod 1 443 and telescopic rod 2 453 have the same structure, refer to... Figure 5 The system includes a telescopic rod body 48 and a sliding part 47. The telescopic rod body 48 and the sliding part 47 are rotatably connected. After each mounting hole is adjusted by telescopic movement, mounting part one 444 and mounting part two 454 can simultaneously reach the position of that mounting hole. During this process, the telescopic rod body 48 rotates a certain angle relative to the sliding part 47, so that adjacent mounting parts one 444 and mounting part two 454 can be combined together and correspond to the mounting holes. Then, screws are used to pass through mounting parts one 444 and mounting part two 454 and align them with the mounting holes of the display body 7, thus realizing the installation of the display body 7.

[0054] After the two telescopic rod bodies 48 are rotated, they tilt at a certain angle and combine with connecting frame one 442 and connecting frame two 452 to form a triangular structure. This not only limits the position of connecting frame one 442 and connecting frame two 452, but also makes the formed shape and installation structure more solid and stable.

[0055] After the above adjustments, the shape and position of mounting component 1 44 and mounting component 2 45 have been determined. Then, the fixing plate is placed at the ends of connecting rod 1 441 and connecting rod 2 451, and the movable strip hole 42 is aligned with it. Finally, it is fixed with screws. Preferably, a limiting groove 43 is provided at the movable strip hole 42. The limiting groove 43 is used to limit the position of connecting rod 1 441 and connecting rod 2 451. When the fixing plate is integrated with mounting component 1 44 and mounting component 2 45 and is not fixed, mounting component 1 44 and mounting component 2 45 can slide relative to the fixing plate.

[0056] The existing display body 7 cannot use a third-party bracket when the mounting part 71 is designed to be embedded. However, the present invention uses mounting component 1 44 and mounting component 2 45 to form an adjustable shape for embedding, and uses a movable telescopic rod to adjust the position to achieve the purpose of installation, so that it can also use a third-party bracket.

[0057] To strengthen the structure of connecting rod 441 and connecting rod 451, a crossbeam 49 is attached between them to limit their position. A support bar 491 is provided on the crossbeam 49, and a lighting component 492 is connected to the end of the support bar 491. The support bar 491 is a corrugated metal tube that supports the lighting component 492. Furthermore, the support bar 491 has a hollow interior for wires to pass through, thus meeting the lighting requirements without the need for a desk lamp, avoiding excessive desktop space occupied by a desk lamp. It also eliminates the need for a clamp-on lighting component 492, which requires significant clamping force to ensure secure holding, but excessive clamping force can easily damage the monitor body 7. Additionally, it only changes the illumination angle, not the illumination position.

[0058] Example 2,

[0059] Reference Figure 8-9When the mounting part 71 of the monitor is flat, the mounting components 1 44 and 2 45 have the same structure, both including a movable part 81 and a telescopic rod 3 82. The movable part 81 has a slot 84, which is inserted into the fixed base 41. The slot 84 has a limiting pin 85, which passes through the movable strip hole 42 to connect the movable part 81 to the movable strip hole 42, allowing the movable part 81 to slide and rotate relative to the movable strip hole 42. Specifically, the movable part 81 consists of a fixed strip 1 and a fixed strip 2. The fixed strip 1 is connected to the limiting pin 85. The fixed strip 1 and the limiting pin 85 have threaded through holes. There is a gap between the fixed strip 2 and the limiting pin 85, and the fixed strip 2 has a threaded hole corresponding to the lower end of the limiting pin 85. After the movable part 81 is adjusted to the correct position, a screw passes through the threaded through hole to... After reaching the threaded hole, tighten continuously to bring the first and second fixing bars closer together to clamp the fixing plate. One end of the telescopic rod 82 is connected to the movable part 81, and the other end is provided with the mounting part 83 for connecting to the mounting hole of the display body 7. In use, bring the whole thing close to the mounting part 71 of the display, and adjust the position of the mounting part 83 by rotating the telescopic rod 82 and extending and retracting it to reach the position of the mounting hole. When the position of the mounting hole is too close or too far, the movable part 81 can slide relative to the fixing plate to make the distance of the telescopic rod further closer or further away from the fixing plate to improve the applicability. In addition, after relative rotation, the extension direction of the telescopic rod 82 is not the same as the extension direction of the movable bar hole 42. When the telescopic rod 82 is fixed in multiple directions, the fixing plate will also be in a fixed state.

[0060] If the monitor body 7 has only two mounting holes, the two adjacent telescopic rods 82 can rotate relatively close to each other under the support of the movable part 81, so that the two mounting parts 83 can be stacked and combined to form a whole. At this time, the two telescopic rods 82 and one side of the fixing plate form a triangular structure, making the overall structure more solid and the load-bearing effect better, and the stability higher.

[0061] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0062] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style of the specification is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other implementations that can be understood by those skilled in the art.
