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] With the continuous advancement of social level, now almost every household has a computer. 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 one is a mechanical arm monitor stand, such as the public technical document "CN 205208096 U, a monitor stand dedicated to engineering cost computer teaching", from its attachment 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. In addition, 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 kind of 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", from its technical solution it can be known that the angle of the monitor can be adjusted up and down, but it cannot be adjusted far and near.

DETAILED DESCRIPTION

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

[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments 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 cannot be understood as limiting the present invention.

[0034] Please refer to Figure 1-8 ;

[0035] The display 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 fixedly connected to the desktop when in use, and can be fixed by screws or clamping. The fixed base 1 is provided with a support portion 2, and a connecting seat 3 is slidably connected to the support portion 2. In this embodiment, the shape of the support portion 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 display and is used for multi-angle steering. It can at least realize the angle adjustment of up, down, left, and right. Preferably, it can also be a rotational angle adjustment. An adjustment structure 4 and a support structure 5 are provided between the connecting seat 3 and the support portion 2;

[0036] For example, the open technical document "CN114658997B, monitor bracket" has the following adjustment scheme: "The first arm is hinged to the first column through the hinge point B, and one end of the first arm is hinged to the connecting member 13 through the 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 around the hinge point C relative to the first column, thereby achieving the effect of adjusting the height of the monitor; at the same time, on the first arm, the hinge point A, the hinge point B and the hinge point C between the elastic member and the first arm are arranged in sequence. Similarly, when a display is mounted on the connecting member 13, according to the moment balance principle, one end of the first arm body bears the load, and the elastic member can apply an elastic force to the other end of the first arm body to keep the first arm body in a force balance, thereby ensuring that the display can automatically hover at any height during the process of adjusting the height of the display"; another example is the public technical document "CN108895283A, display bracket", in which "when the display is assembled to the display connecting plate of the display bracket, the user can adjust the height of the display 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 make the monitor 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 the quality, and has a wider range of applications.

[0039] The present invention relates to an embodiment of the adjustment structure 4, which specifically includes an adjustment component 41 arranged on the back of the support part 2, a pull rod 42 is inserted into the adjustment component 41, and a plurality of transmission belts 43 are connected to the pull rod 42. 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 two ratchets 161 are respectively fixed on both sides of the pull rod 42. The pull rod 42 is rotated synchronously by rotating the ratchet 161, 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, after the display is installed on the connecting seat 3, the tension provided by the tension spring 45 is not enough to pull up the display, and only plays an auxiliary role in this solution; in this embodiment, there are two tension springs 45, one end of which is connected to the two sides of the connecting seat 3 respectively, 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, and 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 inclined downward so that the clamping block 51 can enter the clamping hole 52 more easily. Each clamping hole 52 corresponds to a different height, and the clamping block 51 is tilted downward to be clamped 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 display 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 the bracket does not rely on the balance of force to fix and adjust the display, there is no need to worry about the display bouncing up. In addition, in order to avoid the sudden sinking of the display, it is safer through the dual limitation of the support structure 5 and the adjustment structure 4; when the display 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 to make the card block 51 snap into the corresponding card hole 52. At this time, the tension spring 45 plays an auxiliary role to reduce the force used for output, and then the conveyor belt is rolled up to a suitable state. In this adjustment method, the card block 51 may not be able to snap into the card hole 52. When the user suddenly lets go, the connecting seat 3 falls down along the support part 2 due to 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 falling occurs during upward adjustment, under the limiting effect of the adjustment structure 4, it will only fall to the height before adjustment 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 supporting portion 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 to the hole 52 to prevent falling. Alternatively, the bottom of the display may be supported by one hand, and the adjustment component 41 may 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 push 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 hand is used to operate the block 51. At the same time, the hand operating the block 51 can also support the bottom of the display, thereby preventing the display from falling during adjustment. That is, the supporting structure 5 and the adjusting 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 supporting part 2. When the connecting seat 3 slides to a suitable 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 display is subjected to external force, it will not bounce up or fall down. Moreover, through the double insurance of the supporting structure 5 and the adjusting structure 4, it can withstand a display with a large mass, that is, it is applicable to displays of any size.

[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, and can better interact with the user to meet the user's hands-on operation needs. In addition, these structures are not decorations, but can be actually used and exposed to the outside, so that the user can see how to move more directly. In the process of downward adjustment, the support structure 5 and the adjustment structure 4 constrain each other, and the corresponding actions need to be coordinated to achieve the adjustment;

[0046] It is further explained that in real life, the state 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 injuries. 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 block 51 has at least two 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; 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 separated from the card hole 52 when the connecting rod 53 is pushed 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 clamping blocks 51 can be reset by the torsion spring 1 and clamped into the clamping hole 52 .

[0049] Another embodiment of the adjustment assembly 41 of the present invention is shown in FIG. Figure 3 , specifically including a frame 411, the frame 411 has a plurality of card plates 412 distributed longitudinally, the frame 411 is arranged at the lower half of the support part 2, the plurality of card plates 412 are arranged to be inclined downward, an adjustment gear 413 is formed between adjacent card plates 412, each adjustment gear 413 corresponds to a card hole 52, the pull rod 42 is inserted into the adjustment gear 413 and fixed by card connection, and a clearance position 414 for the movement of the transmission belt 43 is provided in the frame 411. The transmission belt 43 in this embodiment has two, and they are flat belts, which looks more textured, so two clearance positions 414 are provided in the frame 411, one end of the two transmission belts 43 is respectively fixed on the pull rod 42, and the two transmission belts 43 are wound around the transition piece 44 and then connected to the connecting seat 3. When adjusting, the position of the card hole 52 cannot be seen due to the obstruction of the display, and can only be felt, but the adjustment gear 413 can be seen;

[0050] It is not ruled out that there is a method of adjustment 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 move the connecting seat 3 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 inserted into the corresponding adjustment gear 413. During the adjustment process, the adjustment gear 413 can be intuitively seen by the user. If the user loses control during the adjustment process, the block 51 and the hole 52 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. Another 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, reference can be made to the relevant structure of the prior art.

[0052] Further, the fixed base 1 includes a fixing portion 11, the fixing portion 11 is used to be fixed to the desktop, a rotating shaft 12 is passed through the fixing portion 11, a connecting member 13 is fixedly provided on 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 as the center, a torsion spring 14 is provided between the connecting member 13 and the fixing portion 11, and the 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 fixedly arranged at the end of the rotating shaft 12, and a plurality of arc-shaped slots 153 are arranged 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, the number of the arc-shaped slots 153 is six, and the corresponding elastic arms also have six. When the supporting 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 moved from the arc-shaped slots 153. The support part 2 is disengaged from the center, rotates a certain angle and reaches the next arc-shaped slot 153 and is then clamped and fixed. At this time, the support part 2 is in an inclined state, and the torsion spring 14 provides a reset torque to prevent the support part 2 from rotating backward. Of course, it only plays an auxiliary role here, and mainly relies on the balancing force formed by the clamping and fixing of several elastic arms and the arc-shaped slot 153. Each elastic arm and the arc-shaped slot 153 will form a fixed point, and external force needs to be applied to it to break such a balance. Therefore, even if the support part 2 is in a tilted state, it can still maintain balance;

[0055] It should be noted that after the display is fixedly mounted on the connection base 3, it is not located at the farthest upper end of the support part 2. When the angle needs to be adjusted, the hand can be placed at the farthest end of the support part 2 and external force can be applied. By using the principle of lever, only a small force needs to be applied to rotate the support part 2, so the 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 outer side 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. In addition, it will make a "da da da" sound every time it rotates, which has a more mechanical feel both visually and aurally.

[0057] Implementation method 2, refer to Figure 6 , specifically comprising a ratchet 161 fixedly arranged at the end of the rotating shaft 12, the ratchet 161 is engaged with a pawl 162, a lever 163 is rotatably connected in the fixed part 11, a torsion spring 3 164 is arranged between the lever 163 and the fixed part 11, and both ends of the lever 163 pass through the fixed part 11 and are connected with the pawls 162 at both ends; in this embodiment, the torsion spring 2 14 has a large torque. Assuming that a 27-inch display is installed on the connecting seat 3, it can still provide a torque to reset the support part 2 in a tilted state; when the angle needs to be adjusted, an external force is applied to the end of the support part 2 to overcome the torque generated by the torsion spring 2 14, so that the support part 2, the rotating shaft 12 and the ratchet 161 rotate, and after reaching a certain position, the pawl 162 is engaged with the ratchet 161 again to prevent the rotating shaft 12 from rotating, and at the same time, the torsion spring 2 14 applies a reset torque to keep the support part 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, and then reduces the external force applied to the support part 2. The support part 2 rotates back under the action of the second torsion spring 14, and the lever 163 is released after reaching a certain position. Under the action of the third torsion spring 164, the lever 163 is reset, so that the pawl 162 is again engaged with the ratchet 161 to fix 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 therein in the initial state. At this time, the lever 163 cannot be moved, which is 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, in which a through hole 32 adapted to the shape of the supporting portion 2 is provided. Slide grooves 22 are provided on both sides of the supporting portion 2. The slide grooves 22 extend downward and gradually narrow at the ends. Limiting protrusions 33 are provided at positions corresponding to the slide grooves 22 on both sides of the sliding portion 31. The limiting protrusions 33 are provided on the connecting seat 3. When an unexpected fall occurs, the gradually narrowing slide 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 slide groove 22 during the falling process. The limiting protrusions 33 and the slide groove 22 can limit the sliding state of the connecting seat 3 and the supporting 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 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
