Description

Technical Field

[0001] The invention belongs to the technical field of computer accessories, in particular to a mechanical industrial style pull-rod type adjustable display bracket. Background Art

[0002] As the social level continues to improve, now almost every household has a computer, and with the booming development of the e-sports industry, people are no longer limited to owning a computer, but will add more accessories to the computer to make it cooler and more comfortable to use. The most common accessory is an adjustable monitor stand, which can adjust the height and angle of the monitor to meet the different needs of users. The most common one is the mechanical arm monitor stand, such as the public technical document "CN 205208096 U, a special monitor stand for engineering cost computer teaching", from its accessories Figure 1 and attached Figure 2 The specific structure can be seen in the figure. The mechanical arm bracket is more flexible to adjust, but it requires a larger adjustment range. Moreover, since it is equipped with a gas rod, the most common one is a nitrogen spring. The downward adjustment of the monitor uses its own gravity, that is, the smaller monitor has a smaller mass and will be lifted up by the nitrogen spring, and cannot move downward. The larger monitor has a larger mass and will exceed the bearing capacity of the nitrogen spring, and cannot move upward. Only when the nitrogen spring and the actual mass reach a balance can the adjustment be stable. Therefore, this similar bracket has requirements for the size of the monitor.

[0003] There is also a fixed bracket, such as the public technical document "CN 108895283 A, monitor bracket", which can realize the vertical adjustment of the monitor angle, but cannot realize the adjustment of the distance.

[0004] In addition, the brackets on the market are all of the same style. Even if there are differences, they are only partial changes. Mechanical structures have a natural appeal to male users, but the existing brackets obviously cannot do this. Even if there are mechanical styles, they are only decorative structures. These structures are not utilized and lack the mechanical texture of linkage. Summary of the Invention

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0033] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0034] Please refer to Figure 1-8 ;

[0035] The monitor stand described in the present invention has a multi-axial adjustment function, and adopts a mechanical industrial style to achieve the relevant adjustment function. It is not decorative, and has made new breakthroughs in appearance and function. It specifically includes a fixed base 1, which is fixed to the desktop when in use. It can be fixed with screws or clamped. The fixed base 1 is provided with a support part 2, and a connecting seat 3 is slidably connected to the support part 2. In this embodiment, the shape of the support part 2 is not limited. For example, it can be a column or a plate, and the corresponding connecting seat 3 is adjusted accordingly. The connecting seat 3 is used to install the monitor and is used for multi-angle steering. It can at least achieve up, down, left, and right angle adjustment, and preferably can also perform rotational angle adjustment. An adjustment structure 4 and a support structure 5 are provided between the connecting seat 3 and the support part 2;

[0036] For example, the disclosed technical document "CN114658997B, monitor stand" has the following adjustment scheme: "The first arm is hinged to the first column via a hinge point B, and one end of the first arm is hinged to the connecting member 13 via a hinge point C. Thus, by lifting or pressing the end of the first arm connected to the connecting member 13, the first arm can rotate relative to the first column around the hinge point C, thereby achieving the effect of adjusting the height of the monitor; at the same time, on the first arm, the hinge point A, hinge point B and hinge point C between the elastic member and the first arm are arranged in sequence. Similarly, when a monitor is mounted on the connecting member 13, according to the principle of moment balance, one end of the first arm bears the load, and the elastic member can exert an elastic force on the other end of the first arm to maintain the force balance of the first arm, thereby ensuring that the monitor can automatically hover at any height during the process of adjusting the monitor height. Another example is the public technical document "CN108895283A, Monitor Stand", which states that "when the monitor is assembled to the monitor connecting plate of the monitor stand, the user can adjust the height of the monitor as needed by setting the telescopic rod."

[0037] According to the above-mentioned public technical documents, in order to achieve arbitrary height adjustment, the current bracket basically adopts a force balance method without locking. This method is unsafe. When the monitor is accidentally touched, the bracket will drop, that is, the height of the monitor will sink, and it may even sink to the bottom and touch the table. If a lighter monitor is used, since the tension of the components in the bracket is constant, the force balance may be broken and the monitor may even rebound upwards and hit a person.

[0038] In this embodiment, after the display is installed on the connecting base 3, the current position of the connecting base 3 is fixed by the supporting structure 5 so that it will not move up or down. Most of the gravity of the entire display is borne by the supporting structure 5, and the other part of the gravity is borne by the adjusting structure 4. When the height of the display needs to be adjusted, the height can be adjusted by unlocking the supporting structure 5 and then pulling the adjusting structure 4. After the position adjustment is completed, the position of the display is fixed, and its position will not change even if an external force touches the display, which is safer. In addition, this bracket can be applied to all displays, regardless of their weight, and has a wider range of applications.

[0039] The present invention relates to an embodiment of an adjustment structure 4, which specifically includes an adjustment component 41 arranged on the back of the support portion 2, a pull rod 42 is passed through the adjustment component 41, and the pull rod 42 is connected to a plurality of transmission belts 43. The adjustment component 41 has the function of pulling and retracting the transmission belt 43. For example, it can be a ratchet 161 structure, and the two ratchets 161 are respectively fixed on both sides of the pull rod 42. By rotating the ratchet 161, the pull rod 42 is rotated synchronously, thereby realizing the pulling and retracting action of the transmission belt 43. In addition, when there is no external force, the adjustment component 41 is in a locked state; the transmission belt 43 is wound around the transition piece 44, the transition piece 44 is preferably a roller, and the other end of the conveyor belt is connected to the connecting seat 3, and a tension spring 45 and a support structure 5 are provided between the connecting seat 3 and the support portion 2. The tension spring 45 is used to provide an upward pulling force to the connecting seat 3. It should be noted that although the tension spring 45 can provide an upward pulling force, when the display is installed on the connecting seat 3, the tension provided by the tension spring 45 is not sufficient to pull up the display, and in this solution it only plays an auxiliary role; in this embodiment, there are two tension springs 45, one end of which is connected to both sides of the connecting seat 3, and the other end is connected to the end of the support portion 2;

[0040] Furthermore, the support structure 5 includes a clamping block 51 rotatably connected to the bottom of the connecting seat 3. A plurality of clamping holes 52 are longitudinally distributed on the front side of the support portion 2. The clamping holes 52 are designed to be tilted downward so that the clamping block 51 can be more easily inserted into the clamping hole 52. Each clamping hole 52 corresponds to a different height. The clamping block 51 is tilted downward to engage with the clamping hole 52. Preferably, the clamping block 51 is designed in an "L" shape.

[0041] Taking the vertical state of the support part 2 as an example, after the monitor is installed in the connecting seat 3, its gravity is concentrated in the vertical downward direction, and most of the gravity is supported by the clamping fixation of the clamping block 51 and the clamping hole 52, and the adjustment component 41 locks the pull rod 42, and with the cooperation of the pull rod 42 and the transmission belt 43, an upward pulling force is applied to the connecting seat 3, which plays an auxiliary insurance role. Since this bracket does not rely on the balance of force to fix and adjust the monitor, there is no need to worry about the monitor bouncing up. In addition, in order to avoid the monitor from sinking suddenly, it is safer through the dual limitation of the support structure 5 and the adjustment structure 4; when the monitor needs to be adjusted upward, the transmission belt 43 does not play a limiting role. In one of the adjustment methods, use The user can directly lift the display upwards so that the block 51 is locked into the corresponding hole 52. At this time, the tension spring 45 plays an auxiliary role, reducing the force used for output, and then the conveyor belt is reeled into a suitable state. In this adjustment method, the block 51 may not be able to be locked into the hole 52. When the user suddenly lets go, the connecting seat 3 falls down along the support part 2 under the action of gravity. At this time, the length of the transmission belt 43 has not changed. After falling to a certain position, the transmission belt 43 will be straightened to limit further falling. In other words, when the display is adjusted upwards, if it falls, it will only fall to the height before adjustment under the limiting effect of the adjustment structure 4 and will not fall further. That is, the adjustment distance is short and the falling distance is short, thereby reducing the risk.

[0042] In another upward adjustment method, the connecting base 3 can be slid upward along the support part 2 by changing the length of the transmission belt 43. However, when the connecting base 3 slides upward, the block 51 and the hole 52 are separated, and the block 51 may not be able to be inserted into the other hole 52. When the adjustment component 41 is suddenly released without being locked, there may be a risk of falling. Therefore, in this embodiment, a torsion spring may be provided at the rotating connection of the block 51 to ensure that the block 51 can be fixed with the hole 52 to prevent falling, or the bottom of the display can be supported by one hand and the adjustment component 41 can be operated with the other hand.

[0043] When the display needs to be adjusted downward, since the block 51 cannot be detached in this state after entering the hole 52, it is necessary to shrink the conveyor belt a little, and then manually move the block 51 to make it come out of the hole 52. The block 51 is set at the bottom of the connecting seat 3. At this time, one hand is used to operate the adjustment component 41, and the other is used to operate the block 51. At the same time, the hand operating the block 51 can support the bottom of the display, thereby preventing the display from falling during adjustment. That is, the support structure 5 and the adjustment structure 4 lose support for the connecting seat 3 at the same time, and the gravity of the display is used to make the connecting seat 3 slide downward along the support part 2. When the connecting seat 3 slides to the appropriate position, the block 51 is inserted into the hole 52 and fixed, and then the adjustment component 41 is locked.

[0044] The present invention is different from the traditional bracket adjustment. It adopts a new fixing method. When the monitor is subjected to external force, it will not bounce up or fall down. Moreover, through the double insurance of the support structure 5 and the adjustment structure 4, it can withstand large-mass monitors. That is, it is applicable to monitors of all sizes.

[0045] In addition, the structure adopted in the present invention is also very simple. Most of the parts, such as the adjustment structure 4 and the support structure 5, can be assembled by themselves, which can better interact with the user and meet the user's hands-on operation needs. In addition, these structures are not decorative, but can be used in practice and exposed to the outside, so the user can see how to move more directly. During the downward adjustment process, the support structure 5 and the adjustment structure 4 constrain each other, and corresponding actions are required to achieve adjustment.

[0046] It is further explained that in real life, the status of the display usually needs to be adjusted when it is first used, and there is generally little opportunity to adjust it later. Therefore, the above method is not troublesome. On the contrary, accidents often occur in life and the display may be hit, causing injury. The structure of the present invention can solve this problem well. The design style is more inclined to mechanical industrialization, breaking the conventional design of existing products.

[0047] Based on the above technical solution, the card block 51 has at least two, refer to Figure 2 , several card blocks 51 are connected by a connecting rod 53, and several card blocks 51 are set at the same height. Each card block 51 is provided with a longitudinally distributed card hole 52; the several card blocks 51 are connected to form a whole by the connecting rod 53. Based on the above-mentioned height adjustment method, the hand usually supports the bottom of the display, and the card block 51 can be disengaged from the card hole 52 when the connecting rod 53 is moved by the finger, which is more convenient for operation.

[0048] Preferably, a torsion spring 1 (not shown) is provided at the rotation connection of the clamping block 51. When adjusted to a suitable position, the connecting rod 53 can be released, and the torsion spring 1 can be used to reset the clamping blocks 51 and clamp them into the clamping holes 52.

[0049] Another embodiment of the adjustment component 41 of the present invention is shown in FIG. Figure 3 The cam 412 is connected to the support frame 211 by a plurality of latches 412, and the latches 412 are connected to the support frame 211 by a plurality of latches 412.

[0050] It is not ruled out that there is a way to adjust by relying solely on the pull rod 42. When the height needs to be adjusted upward, it is necessary to disengage from the current adjustment gear 413, and then pull it downward to make the connecting seat 3 move upward. Since the tension spring 45 can offset most of the downward gravity of the display, the pull rod 42 only needs to apply a small force downward to achieve adjustment. After reaching the desired height, the pull rod 42 is snapped into the corresponding adjustment gear 413. During the adjustment process, the adjustment gear 413 can be intuitively seen by the user. If you lose your grip during the adjustment process, there are still card blocks 51 and card holes 52 that cooperate to fix it to prevent it from falling.

[0051] In an embodiment of the present invention, the fixed base 1 is used to be fixedly connected to the desktop, and the angle of the support part 2 can be adjusted, that is, the support part 2 can be rotated relative to the fixed base 1, so as to realize the movement away from the display. There are two optional brackets in the present invention. After the fixed base 1 is installed on the desktop, one situation is that the support part 2 is perpendicular to the desktop. The adjustment angle of this style is usually less than 40° to rotate away from the user. The other situation is that the support part 2 is tilted toward the user. This method can provide a larger distance adjustment range, usually an adjustment range of 60°. Of course, a limiting structure should be provided in the fixed base 1 to limit the rotation range of the support part 2. For details, please refer to the relevant structure of the prior art.

[0052] Furthermore, the fixed base 1 includes a fixing portion 11, which is used to be fixed to the desktop. A rotating shaft 12 is passed through the fixing portion 11, and a connecting member 13 is fixed to the rotating shaft 12. A mounting position 21 is provided at the bottom of the support portion 2. The rotating shaft 12 passes through both sides of the mounting position 21, and the support portion 2 is fixedly connected to the connecting member 13, so that the support portion 2 can rotate around the rotating shaft 12. A second torsion spring 14 is provided between the connecting member 13 and the fixing portion 11. The second torsion spring 14 provides a resetting torque to the support portion 2. The rotating shaft 12 passes through both ends of the fixing portion 11, and a fixing structure is provided between the connections.

[0053] In this embodiment, the fixing structure has two implementation modes:

[0054] Implementation method 1, refer to Figure 4 and Figure 5 Specifically, it includes a rhythm piece 151 fixed to the end of the rotating shaft 12, and a plurality of arc-shaped slots 153 are provided in a circular array on the end surface of the fixing portion 11. One end of the elastic arm in the rhythm piece 151 is engaged with the arc-shaped slot 153. The more arc-shaped slots 153 there are, the finer the adjustable angle is. Preferably, there are six arc-shaped slots 153, and the corresponding elastic arms also have six. When the support portion 2 rotates relative to the fixing portion 11, the rotating shaft 12 rotates accordingly and pushes the torsion spring 2 14. At the same time, the ends of the six elastic arms are simultaneously released from the arc-shaped slots 153. The support part 2 is disengaged from the center and rotates a certain angle to reach the next arc-shaped slot 153 and then is fixed. At this time, the support part 2 is in a tilted state. The torsion spring 14 provides a restoring torque to prevent the support part 2 from rotating backward. Of course, it only plays an auxiliary role here. The main force depends on the balancing force formed by the clamping and fixing of the multiple elastic arms and the arc-shaped slots 153. Each elastic arm and the arc-shaped slot 153 form a fixed point. External force needs to be applied to it to break this balance. Therefore, even if the support part 2 is in a tilted state, it can maintain balance.

[0055] It should be noted that after the display is fixedly mounted on the connecting base 3, it is not located at the farthest upper end of the support part 2. When the angle needs to be adjusted, you can place your hand at the farthest end of the support part 2 and apply external force. Using the principle of leverage, only a small force is needed to rotate the support part 2, so adjustment is not difficult.

[0056] Preferably, the rotating shaft 12 is also fixed with a metal spring 152, and the second spring arm of the metal spring 152 is in conflict with the first spring arm. Usually, the spring arm is made of plastic material, and fatigue will occur after multiple rotations, resulting in irreversible deformation. For this reason, the metal spring 152 is added for assistance, and external force is applied to the spring arm at all times to reset it. Furthermore, a transparent outer cover 154 is provided on the outside of the fixed part 11 to wrap the spring arm and the metal spring 152. The metal spring 152 has a metallic color and can be seen from the outside through the outer cover 154. Moreover, it will make a "clicking" sound with each rotation, which is more mechanical both visually and aurally.

[0057] Implementation method 2, refer to Figure 6 , specifically including a ratchet 161 fixedly mounted on the end of the rotating shaft 12, the ratchet 161 is engaged with a pawl 162, a lever 163 is rotatably connected to the fixed portion 11, a torsion spring 3 164 is provided between the lever 163 and the fixed portion 11, and both ends of the lever 163 pass through the fixed portion 11 and are connected to the pawls 162 at both ends; in this embodiment, the torsion spring 2 14 has a large torsional force. Assuming that a 27-inch monitor is installed on the connecting seat 3, it can still provide a torque to reset the support portion 2 in a tilted state; when the angle needs to be adjusted, an external force is applied to the end of the support portion 2 to overcome the torque generated by the torsion spring 2 14, so that the support portion 2, the rotating shaft 12 and the ratchet 161 rotate. After reaching a certain position, the pawl 162 is engaged with the ratchet 161 again to prevent the rotating shaft 12 from rotating. At the same time, the torsion spring 2 14 applies a reset torque to keep the support portion 2 in a tilted state;

[0058] When the support part 2 needs to rotate back, one hand presses the end of the support part 2, and the other hand presses the lever 163 to disengage the pawl 162 from the ratchet 161, then reduces the external force applied to the support part 2, and the support part 2 rotates back under the action of the second torsion spring 14. After reaching a certain position, the lever 163 is released, and under the action of the third torsion spring 164, the lever 163 is reset, so that the pawl 162 is engaged with the ratchet 161 again and fixed in the current state.

[0059] Preferably, a locking structure may also be provided, referring to Figure 7 , fix the lever 163 to avoid accidental touch, for example, set an embedding groove 165 on the ratchet teeth of the ratchet 161, and the pawl 162 is embedded in it in the initial state. At this time, the lever 163 cannot be moved and is in a locked state. It is necessary to apply a downward force to the support part 2 to rotate it, and at the same time rotate the ratchet 161 to make the pawl 162 come out of the embedding groove 165, and then adjust it.

[0060] In the embodiment of the present invention, referring to Figure 8The connecting seat 3 includes a sliding portion 31, and a through hole 32 is provided in the sliding portion 31 that is adapted to the shape of the support portion 2. A sliding groove 22 is provided on both sides of the support portion 2, and the sliding groove 22 extends downward and gradually narrows at the end. Limiting protrusions 33 are provided on both sides of the sliding portion 31 at positions corresponding to the sliding groove 22. The limiting protrusions 33 are provided on the connecting seat 3. When an unexpected fall occurs, the gradually narrowing sliding groove 22 can clamp the limiting protrusions 33 to stop it from sliding down. If there is no narrowing design, the limiting protrusion 33 may break when it hits the end of the sliding groove 22 during the falling process. The limiting protrusion 33 and the sliding groove 22 can limit the sliding state of the connecting seat 3 and the support portion 2, and secondly, it can be prevented from falling to the bottom.

[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 embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.

This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. 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.
