Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to a hinge knob and a monitor bracket. Background Technology

[0002] With the increasing popularity and widespread use of televisions, TV stands that can be wall-mounted and offer telescopic and angle adjustments have emerged. To enable quick adjustment, TV stands typically include hinged knobs. These knobs have connectors that link to bolts and a bending force-applying component. Rotating the force-applying component causes the connector to rotate, quickly tightening or loosening the bolts, thus facilitating telescopic or angle adjustments.

[0003] However, since the swing arm of the TV bracket extends horizontally and unfolds or folds horizontally, the force-applying component of the folding knob extends vertically, which affects the folding of the swing arm and thus affects the overall thickness of the TV bracket in the folded state. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a folding knob that can be accommodated in the gap between the two swing arms when the monitor stand is in the folded state, without affecting the folding of the swing arms.

[0005] This utility model also proposes a monitor stand with the aforementioned hinge knob.

[0006] According to a first aspect embodiment of the present invention, the folding knob includes a connector for threaded connection with a threaded component, a force-applying component rotatably connected to the connector, and a locking component connected to both the connector and the force-applying component. The force-applying component is rotatable relative to the connector to switch between a stationary state and a working state. The locking component is configured to hold the force-applying component in the stationary state, wherein:

[0007] In the static state, the connector is parallel to the force-applying component; in the usage state, the connector and the force-applying component are arranged intersectingly.

[0008] The folding knob according to the embodiment of this utility model has at least the following beneficial effects:

[0009] During the transport of the monitor stand, the hinge knob is in a stationary state, with the force-applying component parallel to the connecting component. The swing arms on either side of the hinge knob define a gap for accommodating it, allowing the swing arms to be fully folded to their minimum thickness, reducing transport volume and costs. During installation or use, when adjusting the monitor stand's tilt angle, the force-applying component can be rotated to release the locking mechanism, allowing it to intersect with the connecting component. This facilitates tightening and loosening the threaded parts. After adjusting the monitor stand's tilt angle, the force-applying component can be rotated to switch and remain stationary. This ensures that when the display device mounted on the monitor stand moves relative to the wall, the stationary force-applying component will not interfere with the swing arms. This is especially beneficial when the monitor needs to be placed flush against the wall, minimizing the distance between the monitor and the wall. This design balances the efficiency of the hinge knob adjustment with the stand's folding and storage requirements, achieving a perfect combination of functionality and portability, and enhancing the user experience.

[0010] According to some embodiments of the present invention, the locking member includes a first mating part and a second mating part, wherein either the first mating part or the second mating part is connected to the connecting member, and the other is connected to the force-applying member;

[0011] The first mating part includes a snap-fit ​​protrusion and an elastic element connected to the snap-fit ​​protrusion, and the second mating part defines a snap-fit ​​groove. In the static state, the snap-fit ​​protrusion is subjected to the elastic force of the elastic element and is inserted into or snapped into the snap-fit ​​groove to restrict the relative rotation of the first mating part and the second mating part.

[0012] According to some embodiments of this utility model, the snap-fit ​​groove is an arc-shaped groove. When the force-applying member is driven to rotate relative to the connecting member, the snap-fit ​​protrusion can be disengaged from the arc-shaped groove to switch from the static state to the use state.

[0013] According to some embodiments of the present invention, the connector defines a first mounting groove extending radially along the connector and a first mounting hole extending axially along the connector and communicating with the first mounting groove, the second mating part being connected to the force-applying member and inserted into the first mounting groove, and the first mating part being located in the first mounting hole.

[0014] According to some embodiments of the present invention, the connector further includes a second mounting hole extending radially along the connector, the second mounting hole communicating with the first mounting groove, the second mating part being provided with a third mounting hole communicating with the second mounting hole, and the hinge knob further includes a rotating shaft passing through the second mounting hole and the third mounting hole.

[0015] According to some embodiments of the present invention, the rotating shaft includes a first main body portion defining a hollow cavity, the first main body portion having a slot communicating with the hollow cavity, the slot extending along the axial direction of the rotating shaft and penetrating to both ends of the first main body portion.

[0016] According to some embodiments of the present invention, the first mating part includes a second main body part, the second main body part defining a receiving cavity for accommodating the elastic member and the snap-fit ​​protrusion, the connector further includes a fourth mounting hole extending radially along the connector and communicating with the first mounting hole, the hinge knob further includes a locking member, the locking member passing through the fourth mounting hole and connected to the second main body part.

[0017] According to some embodiments of the present invention, the locking member includes a mounting shaft connected to either the connecting member or the force-applying member, and a torsion spring sleeved on the mounting shaft. The torsion spring is connected to both the connecting member and the force-applying member, and is configured to drive the connecting member and the force-applying member to be arranged in parallel.

[0018] According to a second aspect embodiment of the present invention, a display bracket includes at least two rotatably connected swing arms and a folding knob as described in any of the above embodiments. When the swing arms are in a folded state, the folding knob is in the stationary state, and the folding knob is accommodated in the gap between the two adjacent swing arms.

[0019] According to some embodiments of the present invention, the display bracket includes a threaded component, a frame, and an adjustment frame rotatably connected to the swing arm. The lower end of the adjustment frame is rotatably connected to the frame. The upper end of the adjustment frame and either the frame are provided with an arc-shaped groove, and the other is provided with a through hole. The threaded component passes through the arc-shaped groove and the through hole and is connected to the hinge knob.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0043] With the increasing popularity and widespread use of televisions, TV stands that can be wall-mounted and offer telescopic and angle adjustments have emerged. To enable quick adjustment, TV stands typically include hinged knobs. These knobs have connectors that link to bolts and a bending force-applying component. Rotating the force-applying component causes the connector to rotate, quickly tightening or loosening the bolts, thus facilitating telescopic or angle adjustments.

[0044] However, since the swing arm of the TV bracket extends horizontally and unfolds or folds horizontally, the force-applying component of the folding knob extends vertically, which affects the folding of the swing arm and thus affects the overall thickness of the TV bracket in the folded state.

[0045] To address the aforementioned technical problems, this application proposes a hinge knob 10, which can be applied to a monitor stand. The hinge knob 10 can loosen or tighten the threaded part 50 to adjust and fix the posture of the monitor stand. The hinge knob 10 has a stationary state (see reference). Figure 1 (as shown) and usage status (refer to) Figure 2 As shown), the hinge knob 10 includes a connector 100, a force-applying component 200, and a locking component 300, as... Figures 6 to 8 As shown, connector 100 is used to connect with threaded part 50 on the monitor bracket. (As indicated...) Figure 1 and Figure 2 As shown, the force-applying component 200 is connected to the connecting component 100, and in use, the force-applying component 200 and the connecting component 100 are intersecting to form a force-saving lever arm structure, so that consumers or installers can apply force to rotate the connecting component 100 to tighten or loosen the threaded component 50. In addition, the force-applying component 200 has a flat structure, which is convenient for consumers or installers to hold and rotate after applying force.

[0046] It should be noted that, as Figure 7 As shown, the hinge knob 10 remains connected to the threaded part 50 and will not be removed from the stand before or after the monitor stand is adjusted. Therefore, when tightening or loosening the threaded part 50 by using the hinge knob 10, there is no need to find a suitable wrench, making the operation more convenient and efficient.

[0047] However, because the folding knob 10 is always connected to the threaded part 50, it may interfere with the folding of the swing arm 20. To avoid this problem, the force-applying part 200 of the folding knob 10 is rotatably connected to the connecting part 100, thereby enabling switching between a stationary state and a usage state. In the stationary state, the force-applying part 200 is parallel to the connecting part 100, and the folding knob 10 is held in this stationary state by the locking part 300. This ensures that the swing arm 20 can fold freely, reducing the overall thickness and facilitating storage.

[0048] Specifically, such as Figure 9As shown, during the transportation of the monitor stand, the folding knob 10 is in a stationary state, the force-applying component 200 is parallel to the connecting component 100, and the swing arms 20 located on both sides of the folding knob 10 define a gap for accommodating the folding knob 10, so that the swing arms 20 can be completely folded to their minimum thickness to reduce transportation volume and lower transportation costs. During installation or use, when it is necessary to tilt the monitor stand, the force-applying component 200 can be rotated to release the restriction of the locking component 300, thereby rotating the force-applying component 200 to the working state where it intersects with the connecting component 100, thus facilitating the tightening and loosening of the threaded component 50. Through this design, while ensuring the adjustment efficiency of the folding knob 10, the folding and storage needs of the stand are also taken into account, achieving a perfect combination of functionality and portability, and improving the user experience.

[0049] In some embodiments, such as Figures 3 to 5 As shown, the locking member 300 includes a first mating part 310 and a second mating part 320. Either the first mating part 310 or the second mating part 320 is connected to the connector 100, and the other is connected to the force-applying member 200. The first mating part 310 and the second mating part 320 cooperate to keep the hinge knob 10 in a stationary state.

[0050] More specifically, the first mating part 310 includes a snap-fit ​​protrusion 311, an elastic element 312, and a second main body part 313. One end of the elastic element 312 is connected to the second main body part 313, and the other end is connected to the snap-fit ​​protrusion 311. The snap-fit ​​protrusion 311 can extend or retract relative to the second main body part 313. The second mating part 320 is provided with a snap-fit ​​groove 321 that matches the snap-fit ​​protrusion 311. When the folding knob 10 is in a stationary state, the snap-fit ​​protrusion 311 is inserted into the snap-fit ​​groove 321 by the elastic force of the elastic element 312. The snap-fit ​​protrusion 311 and the snap-fit ​​groove 321 engage or engage, thereby restricting the relative rotation of the first mating part 310 and the second mating part 320, so as to prevent the force-applying member 200 from rotating relative to the connecting member 100 under its own weight, thus being in the position that interferes with the folding of the swing arm 20.

[0051] In some embodiments, an installer can push the latching protrusion 311 to disengage it from the latching slot 321, thereby releasing the locking member 300 and allowing the force-applying member 200 to rotate freely relative to the connecting member 100. In other embodiments, such as Figure 4As shown, the locking groove 321 is an arc-shaped groove 31. When the force-applying member 200 is driven to rotate relative to the connecting member 100, the locking protrusion 311 abuts against the groove wall of the arc-shaped groove 31. As the rotation amplitude increases, the elastic member 312 gradually compresses, and the locking protrusion 311 gradually exits the arc-shaped groove 31 until it is completely disengaged. The locking member 300 releases the restriction on the force-applying member 200, thereby allowing the folding knob 10 to switch from a stationary state to a working state. When switching from the working state to the stationary state, it is only necessary to rotate the force-applying member 200 to be parallel to the connecting member 100, so that the locking protrusion 311 extends out under the elastic force of the elastic member 312 and inserts into the locking groove 321. The locking protrusion 311 and the locking groove 321 engage and lock. Through this engagement, the folding knob 10 can quickly switch between the working state and the stationary state.

[0052] In some embodiments, such as Figure 3 and Figure 4 As shown, the connector 100 defines a first mounting groove 110 and a first mounting hole 120. The first mounting groove 110 is disposed at the end of the connector 100 for rotatable connection with the force-applying member 200 and extends radially, thereby forming a space for accommodating and allowing the second mating part 320 to rotate. The second mating part 320 is connected to the force-applying member 200 and inserted into the first mounting groove 110. The first mounting hole 120 extends axially along the connector 100 and communicates with the first mounting groove 110. The first mating part 310 is disposed in the first mounting hole 120. The second mating part 320 has an arc-shaped structure, with a snap-fit ​​groove 321 provided on its central edge, so that when the force-applying member 200 is parallel to the connector 100, the first mating part 310 and the second mating part 320 can be snapped and locked. Figure 4 In the embodiment shown, the connector 100 is provided with a threaded hole for connecting with the threaded member 50, and the threaded hole is coaxial with and connected to the first mounting hole 120.

[0053] Furthermore, the connector 100 also includes a second mounting hole 130 extending radially along the connector 100, the second mounting hole 130 communicating with the first mounting groove 110, such as... Figure 3 and Figure 5As shown, the first mounting groove 110 has two sides that communicate with a second mounting hole 130. The second mating part 320 is provided with a third mounting hole 322 that communicates with the second mounting hole 130. The folding knob 10 also includes a rotating shaft 400, which passes through the second mounting hole 130 and the third mounting hole 322 to allow the connector 100 and the force-applying member 200 to be rotatably connected. In some embodiments, the length of the rotating shaft 400 is less than the sum of the lengths of the second mounting hole 130 and the third mounting hole 322, so that after the rotating shaft 400 is installed into the second mounting hole 130 and the third mounting hole 322, screws are provided at both ends of the rotating shaft 400 to lock the rotating shaft 400 and prevent the rotating shaft 400 from falling out of the folding knob 10. Alternatively, in other embodiments, such as Figure 5 As shown, the rotating shaft 400 is interference-fitted with the third mounting hole 322, thereby fixing the rotating shaft 400 against the wall of the third mounting hole 322. Both ends of the rotating shaft 400 are clearance-fitted with the second mounting hole 130, so that the force-applying component 200 can drive the rotating shaft 400 to rotate synchronously. It can be understood that both ends of the rotating shaft 400 can also be interference-fitted with the second mounting hole 130, while the middle part is clearance-fitted with the third mounting hole 322, which can also achieve the effect of rotating connection between the force-applying component 200 and the connecting component 100.

[0054] Furthermore, to facilitate the interference fit between the rotating shaft 400 and the third mounting hole 322, the rotating shaft 400 includes a first main body portion 410 defining a hollow cavity. The first main body portion 410 has a slot 411 communicating with the hollow cavity. The slot 411 extends axially along the rotating shaft 400 and penetrates to both ends of the first main body portion 410. The rotating shaft 400 can elastically deform at the slot 411. When subjected to external pressure, the outer diameter of the rotating shaft 400 can gradually decrease, and the width of the slot 411 gradually decreases until the rotating shaft 400 fits into the wall of the third mounting hole 322, thereby achieving fixation. In addition, guide portions 420 are provided at both ends of the rotating shaft 400 along the axial direction. The guide portions are tapered to facilitate the smooth insertion of the rotating shaft 400 into the third mounting hole 322.

[0055] Furthermore, the first mating part 310 also includes a second main body part 313, which defines a receiving cavity for accommodating the elastic member 312 and the snap-fit ​​protrusion 311. The connector 100 also includes a fourth mounting hole 140 extending radially along the connector 100 and communicating with the first mounting hole 120. The hinge knob 10 also includes a locking member 500, which can be a screw. The fourth mounting hole 140 is a threaded hole, so that the locking member 500 is screwed into the fourth mounting hole 140, and the end of the screw abuts against the second main body part 313. Alternatively, the locking member 500 can also be a pin, and the outer peripheral surface of the second main body part 313 is provided with a insertion groove. The pin can pass through the fourth mounting hole 140 and engage with the insertion groove to fix the second main body part 313 in the first mounting hole 120, ensuring the effective engagement of the snap-fit ​​protrusion 311 and the snap-fit ​​groove 321.

[0056] In other embodiments (not shown in the figures), the locking member 300 includes a mounting shaft connected to either the connecting member 100 or the force-applying member 200, and a torsion spring sleeved on the mounting shaft. The two arms of the torsion spring are respectively connected to the connecting member 100 and the force-applying member 200. When the torsion spring is not under external pressure, it can drive the connecting member 100 and the force-applying member 200 to be arranged in parallel, that is, to keep the hinge knob 10 in a stationary state. When it is necessary to switch to the use state, the arm connected to the force-applying member 200 is compressed, the torsion spring undergoes elastic deformation, and the force-applying member 200 bends relative to the connecting member 100. After use, if the operator releases the force-applying member 200, the force-applying member 200 is driven to rotate to a position parallel to the connecting member 100 under the elastic reset action of the torsion spring.

[0057] The second aspect of this application also proposes a monitor stand, such as... Figures 6 to 9 As shown, the monitor bracket can be used to mount monitors such as televisions and computer screens. It includes at least two rotatably connected swing arms 20 and a hinge knob 10 as mentioned in any of the above embodiments. The at least two swing arms 20 are rotatably connected via a rotation axis, allowing them to switch between an unfolded state and a folded state. The folded state specifically refers to the state where the at least two swing arms 20 are rotated relative to each other around the rotation axis until they are collinearly aligned, so that the two swing arms 20 appear to overlap when viewed from the axial direction of the rotation axis. The unfolded state refers to the state where the two swing arms 20 do not overlap when viewed from the axial direction of the rotation axis. When the swing arms 20 are in the folded state, the hinge knob 10 is in a stationary state, allowing it to be accommodated in the gap between its adjacent two swing arms 20.

[0058] Furthermore, such as Figure 7 and Figure 8As shown, the monitor stand includes a frame 30 and an adjustment bracket 40 rotatably connected to a swing arm 20. The lower end of the adjustment bracket 40 is rotatably connected to the frame 30, allowing it to rotate around its lower end as a pivot point, thereby adjusting the monitor's tilt angle or height. The upper end of the adjustment bracket 40 is connected to the frame 30 via a threaded component 50 and a hinge knob 10. Figure 8 As shown, the frame 30 is provided with an arc-shaped groove 31, and the adjustment bracket 40 is provided with a through hole 41. A threaded component 50 passes through the arc-shaped groove 31 and the through hole 41, and is connected to a hinge knob 10. In use, the hinge knob 10 can loosen the threaded component 50, allowing the adjustment bracket 40 to rotate relative to the frame 30. The threaded component 50 slides in the arc-shaped groove 31. After adjustment, the hinge knob 10 tightens the threaded component 50, thus fixing the position of the adjustment bracket 40 relative to the frame 30. This design enables rapid adjustment of the monitor stand's angle or height.

[0059] Furthermore, such as Figure 8 As shown, the through hole 41 is a square hole, and the threaded part 50 has a square structure that passes through the square hole. Thus, the rotation of the threaded part 50 in the through hole 41 is restricted, which can prevent the threaded part 50 from rotating synchronously with the folding knob 10 during the tightening process, which would cause the tightening failure.

[0060] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
