Description

Technical Field

[0001] This utility model relates to the field of bracket technology, and in particular to an angle-adjustable bracket. Background Technology

[0002] In industrial equipment, consumer electronics, and automotive mounts, angle-adjustable brackets are widely used to fix and adjust the position of components such as monitors, cameras, and lighting equipment. Traditional brackets typically employ structures such as bolt-locking, spring-clip, and gear-engagement, all of which suffer from inconvenient adjustment, easy loosening, and complex structures. For example, bolt-locking brackets achieve fixation by tightening bolts to compress friction plates, but they are prone to loosening after prolonged use and have low adjustment accuracy; spring-clip brackets rely on elastic elements for damping, but they are prone to wear, leading to a deterioration in the adjustment feel; gear-engagement brackets provide precise angle fixation, but their complex structure, high cost, and inability to achieve stepless adjustment are all problematic. Therefore, there is an urgent need for an angle adjustment mechanism that is both stable and reliable, as well as easy to operate. Utility Model Content

[0003] Therefore, it is necessary to provide an angle-adjustable bracket that, through the cooperation of a rotation positioning structure, a threaded clamping mechanism, and an anti-detachment component, enables the adjustment of the rotating rod and its fixation at the required position, while effectively preventing the cap from being loosened due to excessive rotation, thus improving the user experience.

[0004] An angle-adjustable bracket includes a base, a rotating rod, an anti-detachment component, and a pressure cap. The base protrudes to form a rotating shaft, the rotating rod is rotatably sleeved on the rotating shaft, the pressure cap is connected to the end of the rotating shaft, and the rotating rod is clamped between the pressure cap and the base. The anti-detachment component includes a sleeve and a fastener. A first end of the sleeve is fixed to the pressure cap, and a second end of the sleeve is slidably inserted into the base along the axial direction of the rotating shaft. The fastener is fixed to the second end of the sleeve and confined within the base.

[0005] In the angle-adjustable bracket provided in this application, the rotating rod can connect to a load, such as a camera or phone holder, bear the torque of the load, such as the leverage force of a phone holder, and transmit the pressure to the base locking structure. A sleeve penetrates the hollow structure of the rotating shaft, restricting the movement of the fasteners within the base cavity, maintaining a certain tensile strength even if the cap is completely loosened. The anti-detachment component prevents the bracket from axially separating under extreme conditions (such as vibration, impact, or locking failure), while also enhancing the stability of the angle locking. Through the cooperation of the rotation positioning structure, the clamping mechanism, and the anti-detachment component, the rotating rod can be adjusted and fixed in the desired position, while effectively preventing the cap from excessively rotating and loosening, thus improving the user experience.

[0006] In one embodiment, the gland has a threaded boss on the side near the base, and the end of the shaft has a first threaded hole, with the boss connected to the first threaded hole.

[0007] In one embodiment, the boss has a fixing hole at one end facing the base, the first end of the sleeve is engaged in the fixing hole, and the first threaded hole passes through the base along the axial direction of the rotating shaft.

[0008] In one embodiment, a baffle is provided in the first threaded hole, and a sliding hole is formed in the middle region of the baffle. The second end of the sleeve passes through the sliding hole, and the radial dimension of the fastener located outside the second end of the sleeve is greater than the diameter of the sliding hole.

[0009] In one embodiment, at least one of the fastener and the gland is spaced apart from the baffle along the axial direction of the pivot.

[0010] In one embodiment, the maximum radial dimension of the fastener extending into the sleeve portion is smaller than the diameter of the first threaded hole.

[0011] In one embodiment, the second end of the sleeve has a second threaded hole, and the fastener is threadedly connected to the second threaded hole.

[0012] In one embodiment, the surface of the rotating rod in contact with the base is provided with a plurality of first rotation positioning structures, which are distributed around the rotating axis; the surface of the base in contact with the rotating rod is provided with a plurality of second rotation positioning structures, which are distributed around the rotating axis, and the first rotation positioning structures and the second rotation positioning structures can be engaged and positioned together.

[0013] In one embodiment, a plurality of first rotary positioning structures and a plurality of second rotary positioning structures are symmetrically distributed relative to the rotation axis, wherein one of the first rotary positioning structures and the second rotary positioning structure is a groove and the other is a protrusion.

[0014] In one embodiment, the groove extends radially along the axis of rotation to form a strip groove structure, and the protrusion extends radially along the axis of rotation to form a strip protrusion structure. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited.

[0026] In industrial equipment, consumer electronics, and automotive mounts, angle-adjustable brackets are widely used to fix and adjust the position of components such as monitors, cameras, and lighting equipment. Traditional brackets typically employ structures such as bolt-locking, spring-clip, and gear-engagement, all of which suffer from inconvenient adjustment, easy loosening, and complex structures. For example, bolt-locking brackets achieve fixation by tightening bolts to compress friction plates, but they are prone to loosening after prolonged use and have low adjustment accuracy; spring-clip brackets rely on elastic elements for damping, but they are prone to wear, leading to a deterioration in the adjustment feel; gear-engagement brackets provide precise angle fixation, but their complex structure, high cost, and inability to achieve stepless adjustment are unrealistic. With the development of smart terminals and automated equipment, users have increasingly higher requirements for brackets, such as stepless adjustment or high-precision segmented positioning, maintaining a constant angle even in vibration environments (such as automotive and industrial equipment), and being able to be adjusted with one hand without additional tools. Therefore, there is an urgent need for an angle adjustment mechanism that is both stable and reliable and easy to operate. This application provides an angle-adjustable bracket. The rotating rod and the base employ radial interlocking teeth, i.e., a protrusion and groove structure, to provide multi-position positioning. The threaded locking of the pressure cap enhances the interlocking pressure, preventing vibration-induced loosening. Axial displacement is limited by the sleeve and fasteners, preventing accidental separation of the bracket. Furthermore, even if the pressure cap loosens, the anti-detachment structure maintains its integrity. The rotating shaft, pressure cap, and anti-detachment components in the angle-adjustable bracket adopt a standardized design, facilitating processing and assembly. The angle-adjustable bracket can be used in electronic products, such as mobile phone holders, tablet holders, and monitor holders; it can also be used in industrial equipment or automotive equipment, such as camera adjustment mechanisms, dashcams, and HUD (head-up display) brackets.

[0027] refer to Figures 1-5 This application provides an angle-adjustable bracket 10, including a base 20, a rotating rod 30, an anti-detachment component 40, and a pressure cap 50. The base 20 protrudes to form a rotating shaft 21. The rotating rod 30 is rotatably sleeved on the rotating shaft 21. The pressure cap 50 is connected to the end of the rotating shaft 21. The rotating rod 30 is clamped between the pressure cap 50 and the base 20. The anti-detachment component 40 includes a sleeve 41 and a fastener 42. The first end 411 of the sleeve 41 is fixed to the pressure cap 50. The second end 412 of the sleeve 41 is slidably inserted into the base 20 along the axial direction of the rotating shaft 21. The fastener 42 is fixed to the second end 412 of the sleeve 41 and is confined within the base 20.

[0028] See Figure 1 , Figure 3 and Figure 4The angle-adjustable bracket 10 includes a base 20, a rotating rod 30, an anti-detachment component 40, and a pressure cap 50. When using the angle-adjustable bracket 10, the base 20 can be placed on the surface of an object. The rotating rod 30 can rotate relative to the base 20. Specifically, the base 20 protrudes to form a rotating shaft 21, and the rotating rod 30 is rotatably sleeved on the rotating shaft 21. In some embodiments, the base 20 is disc-shaped, and the rotating shaft 21 is a hollow cylindrical structure. The pressure cap 50 is a locking component of the angle-adjustable bracket 10. The pressure cap 50 is connected to the end of the rotating shaft 21. By tightening it with threads, axial pressure is generated, making the rotational positioning structure between the rotating rod 30 and the base 20 fit tightly, thereby fixing the angle. Specifically, by tightening the threads, downward pressure is applied to the rotating rod 30, enhancing the friction or meshing strength of the teeth with the base 20. In some embodiments, the pressure cap 50 has fine threads to prevent loosening due to vibration, allowing the angle-adjustable bracket 10 to be fixed in the desired position. The user can control the tightness of the rotating rod 30 by tightening or loosening the pressure cap 50. The rotating rod 30 is clamped between the pressure cap 50 and the base 20. The rotating rod 30 can connect to a load via a fixing part, such as connecting to an electronic device like a mobile phone via a magnetic part, bearing the torque of the load, such as the leverage force of a mobile phone, and transmitting pressure to the locking structure of the base 20. The rotating rod 30 can rotate around the pivot 21 of the base 20 to achieve angle adjustment, and can achieve multi-position or stepless positioning through the rotational positioning structure or friction surface with the base 20. In some embodiments, different interfaces, such as U-grooves or threaded holes, can be provided on the rotating rod 30 to adapt to different devices.

[0029] See Figure 1 and Figure 2The anti-detachment component 40 includes a sleeve 41 and a fastener 42. The sleeve 41 penetrates the hollow structure of the rotating shaft 21, forming a second line of defense independent of the threaded locking. The fastener 42 restricts movement within the cavity of the base 20, maintaining a certain tensile strength even if the pressure cap 50 is completely loosened. The anti-detachment component 40 prevents the bracket from axially separating under extreme conditions (such as vibration, impact, or locking failure), while also enhancing the stability of the angle locking. In some embodiments, the first end 411 of the sleeve 41 is fixed to the pressure cap 50, and the second end 412 of the sleeve 41 is slidably inserted into the base 20 along the axial direction of the rotating shaft 21. The fastener 42 is fixed to the second end 412 of the sleeve 41 and is confined within the base 20. In the normal locking state, when the pressure cap 50 is tightened, the sleeve 41 is pulled upward, and the fastener 42 abuts against the baffle 2110 of the base 20, thereby clamping the rotating rod 30 between the pressure cap 50 and the base 20, with the meshing teeth engaging. The anti-detachment component 40 and the threaded locking structure of the pressure cap 50 complement each other. When the meshing teeth in the threaded structure of the pressure cap 50 wear, the anti-detachment component 40 can still provide backup locking force. When the pressure cap 50 becomes loose, the sleeve 41 falls due to gravity, the fastener 42 gets stuck at the baffle 2110, and the rotating rod 30 cannot axially disengage. In the event of a strong impact, the sleeve 41 slides and buffers against the hole in the base 20, which can prevent structural damage caused by hard collisions. When the angle-adjustable bracket 10 is used in a vehicle mount, the vehicle mount can hold electronic devices. When the vehicle is bumpy, the anti-detachment component 40 can prevent the electronic devices from falling, while allowing for quick angle fine adjustments, which can prevent the devices from being thrown off due to inertia.

[0030] See Figure 3 and Figure 4 A threaded boss 51 is formed on the side of the pressure cap 50 near the base 20. The threaded boss 51 connects the pressure cap 50 and the rotating shaft 21 of the base 20. The end of the rotating shaft 21 has a first threaded hole 211, and the boss 51 is connected to the first threaded hole 211. The axial locking force is transmitted and the angle adjustment damping control is realized through the threaded engagement, which effectively improves the stability of the angle-adjustable bracket 10 and allows for adjustment of the feel. In some embodiments, the first threaded hole 211 extends through the base 20 along the axial direction of the rotating shaft 21. A baffle 2110 is provided in the first threaded hole 211. An annular baffle 2110 is provided in the middle of the first threaded hole 211, which can limit the stroke of the sleeve 41 but allow axial sliding. A sliding hole 2111 is formed in the middle area of ​​the baffle 2110. The second end 412 of the sleeve 41 passes through the sliding hole 2111. The radial dimension of the fastener 42 is located outside the second end of the sleeve 41 and is larger than the diameter of the sliding hole 2111, so as to realize the assembly connection of the fastener 42 and the sleeve 41.

[0031] See Figure 3 and Figure 4In some embodiments, a fixing hole 511 is provided at the end of the boss 51 facing the base 20. The first end 411 of the sleeve 41 is engaged in the fixing hole 511. The fixing hole 511 at the end of the boss 51 and the engaging structure of the first end 411 of the sleeve 41 together constitute the fixation of the anti-detachment component 40. While fixing, it can achieve precise force transmission and assembly stability. In some embodiments, the sleeve 41 and the fixing hole 511 are interference-fitted to ensure that all the rotational force of the pressure cap 50 is transmitted to the anti-detachment component 40, so as to avoid the sleeve 41 slipping when the thread is tightened, and to ensure that the anti-detachment component 40 operates synchronously.

[0032] See Figure 1 and Figure 2 Along the axial direction of the rotating shaft 21, at least one of the fastener 42 and the pressure cap 50 is spaced from the baffle 2110. Specifically, the fastener 42 is spaced from the baffle 2110. In some embodiments, the pressure cap 50 is spaced from the baffle 2110. In some embodiments, both the fastener 42 and the pressure cap 50 are spaced from the baffle 2110. The space between at least one of the fastener 42 and the pressure cap 50 and the baffle 2110 allows the pressure cap 50 to have room to screw in and out, providing axial movement space for the pressure cap 50 when rotating relative to the first threaded hole 211, ensuring that the pressure cap 50 can move freely axially during tightening or loosening, while maintaining the anti-dislodgement function. During assembly, the sleeve 41 can be inserted into the fixing hole 511 of the pressure cap 50 first, and the fastener 42 can be pre-installed, but the fastener 42 is not locked at this time. Further, insert the fastener 42 into the threaded hole as a whole, ensuring that the nut does not contact the baffle 2110, and further tighten the pressure cap 50 to the working position.

[0033] In some embodiments, the maximum radial sleeve 41 portion of the fastener 42 is smaller than the diameter of the first threaded hole 211 to ensure that the fastener 42 can pass through the first threaded hole 211, thereby confining the fastener 42 within the base 20. In some embodiments, the second end 412 of the sleeve 41 has a second threaded hole 4121, to which the fastener 42 is threadedly connected, preventing the fastener 42 from coming out. By screwing the fastener 42 into the second threaded hole 4121, the fastener 42 can be stably fixed to the base 20.

[0034] In some embodiments, the surface of the rotating rod 30 in contact with the base 20 is provided with multiple first rotation positioning structures 60. The rotating rod 30 near the base 20 can be configured as a disc-shaped structure. Multiple second rotation positioning structures 70 can be spaced apart along the axial direction of the disc-shaped base 20. The surface of the base 20 in contact with the rotating rod 30 is provided with multiple second rotation positioning structures 70, which are distributed around the rotation axis 21. The base 20 can be configured as a disc-shaped structure, and the multiple second rotation positioning structures 70 can be spaced apart along the axial direction of the disc-shaped base 20. The multiple second rotation positioning structures 70 are distributed around the rotation axis 21. The first rotation positioning structures 60 and the second rotation positioning structures 70 match and cooperate to achieve snap-fit ​​positioning. Through mechanical interlocking, the multi-position precise positioning and anti-torsion self-locking of the angle-adjustable bracket 10 can be achieved.

[0035] See Figure 3 and Figure 4Multiple first rotary positioning structures 60 and multiple second rotary positioning structures 70 are symmetrically distributed relative to the rotating shaft 21. In some embodiments, the first rotary positioning structure 60 is a groove 61 extending radially along the rotating shaft 21, and the second rotary positioning structure 70 is a protrusion 71 extending radially along the rotating shaft 21. Specifically, the rotating rod 30 and the base 20 can adopt a completely symmetrical rotary positioning structure, with all grooves 61 and protrusions 71 arranged radially at equal angles with respect to the center of the rotating shaft 21, ensuring a completely consistent biting force and positioning feel regardless of the angular position of the rotating rod 30. In other embodiments, the first rotary positioning structure 60 is a protrusion 71, and the second rotary positioning structure 70 is a groove 61. The symmetrically distributed rotary positioning structure ensures that the angle-adjustable bracket 10 has the same operating torque during forward and reverse rotation, avoiding jamming during unidirectional adjustment. The groove 61 is configured as a radial groove on the contact surface of the rotating rod 30. The groove extends strictly outward along the radius of the rotating shaft 21, allowing the sidewalls of the groove 61 to uniformly bear the compressive stress from the protrusion 71 and avoid local stress concentration. In some embodiments, the groove 61 extends radially along the rotating shaft to form a strip-shaped groove structure, and the protrusion 71 extends radially along the rotating shaft 21 to form a strip-shaped protrusion structure. The bottom of the groove 61 adopts a progressive depth design, providing gentle guidance in the initial stage of engagement and achieving rigid positioning when fully engaged. The corresponding radial protrusions on the contact surface of the base 20 have a mirror-matching profile with the groove 61. The top of the protrusion 71 adopts a micro-arc transition to ensure smooth entry when in contact with the groove 61. The guide ramps on both sides of the protrusion 71 enable the engagement process to have a self-centering function, automatically correcting the position even with minor assembly deviations. When the user adjusts the angle of the adjustable bracket 10, the torque applied to the rotating rod 30 first overcomes the elastic deformation force between the groove 61 and the protrusion 71, at which point a clear sense of the gear position can be felt. Continuing to apply force causes the protrusion 71 to climb past the apex of the groove 61, and the rotating rod 30 quickly positions itself at the next groove 61, accompanied by a crisp "click" sound, providing both tactile and audible confirmation of operation and enhancing the user experience.

[0036] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
