Description

Technical Field

[0001] This invention relates to the field of support technology. More specifically, this invention relates to a clutch-type cantilever support. Background Technology

[0002] A cantilever bracket is a type of support used to hold audio-visual devices such as mobile phones, tablets, microphones, or cameras. Its applications include video shooting, video conferencing, live streaming, reading, and gaming.

[0003] A traditional cantilever bracket includes a base, a vertical pole, a lifting arm, and bolts. One end of the lifting arm connects to a support device that supports the object being supported, and the other end is equipped with a first gear plate. One end of the vertical pole is fixedly connected to the base, and the other end is equipped with a rotary joint with a second gear plate. The bolt passes through both the first and second gear plates, allowing them to move axially and switch their engagement / disengagement states. When the bolt is loosened, the first and second gear plates separate, allowing the user to rotate the lifting arm upwards or downwards to adjust the angle between the lifting arm and the vertical pole. When the bolt is tightened, the first and second gear plates fit tightly together and mesh, fixing the lifting arm to the vertical pole; the angle between the lifting arm and the vertical pole is not adjustable. This type of cantilever bracket adjusts the angle between the lifting arm and the vertical pole by tightening and loosening the bolts. Because bolts are threaded fasteners, after repeated tightening and loosening operations, the outer surface of the bolt, the connection between the first and second gears, all become severely worn. This causes the bolt to slip during tightening, preventing the first and second gears from meshing and the upright from supporting the lifting arm at the predetermined angle. Furthermore, tightening and loosening the bolts is cumbersome and inconvenient to use. Summary of the Invention

[0004] One objective of this application is to solve the above-mentioned problems and provide corresponding beneficial effects.

[0005] Another objective of this application is to provide a clutch-type cantilever bracket, which solves the technical problems of how to improve the stability of the lifting arm supported by the upright at a predetermined angle, and how to improve the ease of use of the clutch-type cantilever bracket. This is mainly achieved through the following technical solutions:

[0006] This application provides a clutch-type cantilever bracket, comprising:

[0007] The table clamp, upright, lifting arm, clutch disc assembly, drive disc assembly, and synchronous belt are provided. The table clamp is used to fix the clutch-type cantilever bracket to the table. One end of the upright is connected to the table clamp, and the other end is connected to one side of the lifting arm through the clutch disc assembly. The other side of the lifting arm is connected to the drive disc assembly.

[0008] The clutch assembly includes a first turntable with a first toothed disc, a through shaft with at least a pair of guide pins, a bushing with a second toothed disc and at least a pair of mounting holes, a clutch, a first reset member, and a second turntable. The first turntable is connected to the upright. One end of the through shaft is connected to the first turntable, and the other end is connected to the second turntable. The bushing is fitted onto the outer side wall of the through shaft. The clutch is fitted onto the outer peripheral wall of the bushing. One end of the clutch is provided with a first protrusion structure, and the first protrusion structure is provided with a limiting groove. The other end of the clutch is provided with a synchronous pulley. At least a pair of inclined sliding grooves are provided in the middle of the clutch. Each guide pin passes through a corresponding mounting hole and is slidably connected to the corresponding inclined sliding groove. The first reset member is fitted onto the outer peripheral wall of the bushing. One end of the first reset member is accommodated in the limiting groove, and the other end abuts against the side wall of the second toothed disc. The second turntable is connected to the lifting arm.

[0009] The timing belt is connected to the timing pulley, and the timing belt is connected to the drive disk assembly. The drive disk assembly is also used to connect to the support device that supports the supported object.

[0010] When the drive disk assembly drives the synchronous belt drive, the synchronous belt drives the clutch to rotate in the first direction. Each guide pin slides in the corresponding inclined groove as the clutch rotates, driving the bushing to move in the direction of the second turntable and compressing the first reset member, so that the second gear plate separates from the first gear plate. At this time, the lifting arm can be rotated up or down to adjust the angle between the lifting arm and the upright.

[0011] When the drive disk assembly stops driving the synchronous belt drive, the bushing is moved towards the first gear disk by the elastic force of the first reset member. The bushing drives the clutch to rotate in the second direction through each guide pin until the second gear disk meshes with the first gear disk. At this time, the clutch is locked and the angle between the lifting arm and the upright is not adjustable.

[0012] This application provides a clutch-type cantilever bracket including a table clamp, a vertical pole, a lifting arm, a clutch disc assembly, a drive disc assembly, and a timing belt. One end of the vertical pole is connected to the table clamp, and the other end is connected to one side of the lifting arm via the clutch disc assembly. The other side of the lifting arm is connected to the drive disc assembly. The timing belt is used to connect the drive disc assembly and the clutch disc assembly. The drive disc assembly is also used to connect to a support device that supports the supported object. Thus, the clutch-type cantilever bracket of this application embodiment can stably support the supported object. This application embodiment designs the clutch disc assembly as including a first turntable with a first toothed disc, a through shaft with at least a pair of guide pins, a bushing with a second toothed disc and at least a pair of mounting holes, a clutch, a first reset member, and a second turntable. The first turntable is connected to the upright, one end of the through shaft is connected to the first turntable, and the other end is connected to the second turntable. The bushing is fitted onto the outer side wall of the through shaft, and the clutch is fitted onto the outer peripheral wall of the bushing. One end of the clutch is provided with a first protrusion structure with a limit groove, and the other end is provided with a synchronous pulley. The middle of the clutch is provided with at least a pair of oblique sliding grooves. The pin passes through the corresponding mounting hole and slides into the corresponding inclined groove. The first reset component is sleeved on the outer peripheral wall of the bushing. One end of the first reset component is housed in the limiting groove, and the other end abuts against the side wall of the second gear plate. The second turntable is connected to the lifting arm. Thus, the drive plate assembly can drive the synchronous belt drive, drive the clutch to rotate, thereby driving the bushing to move, realizing the separation or engagement of the first gear plate and the second gear plate. When the first gear plate and the second gear plate are separated, the angle between the lifting arm and the upright can be adjusted. When the first gear plate and the second gear plate are engaged, the clutch is locked, and the angle between the lifting arm and the upright cannot be adjusted. Compared with the prior art of adjusting the angle between the lifting arm and the upright by bolts, the clutch disc assembly used in this application embodiment achieves the separation and engagement of the first and second gear discs by driving the guide pin to slide in the inclined groove through the clutch. This can effectively avoid wear on the first and second gear discs and prevent slippage caused by wear on the first and second gear discs. This allows the upright to support the lifting arm at a predetermined angle, thereby improving the stability of the upright supporting the lifting arm at the predetermined angle.

[0013] The clutch-type cantilever bracket of this application embodiment is easy to operate. Pressing the clutch lever allows adjustment to the desired height and position, and releasing the clutch lever allows for stopping at any point. In other words, one-button adjustment enables easy and flexible adjustment of the lifting arm, with no frictional resistance and effortless operation.

[0014] In this embodiment, a table clamp is used to fix the clutch-type cantilever bracket to the desktop. The table clamp has a wide range of compatibility and is stable and reliable, which helps to increase the application scenarios of the clutch-type cantilever bracket.

[0015] In some technical solutions, each pair of guide pins includes a first guide pin and a second guide pin, wherein the first guide pin is disposed on one side of the through shaft and the second guide pin is disposed on the other side of the through shaft;

[0016] Each pair of mounting holes includes a first mounting hole and a second mounting hole, wherein the first mounting hole is located on one side of the bushing and the second mounting hole is located on the other side of the bushing;

[0017] Each pair of inclined slides includes a first inclined slide and a second inclined slide, with the first inclined slide disposed on one side of the clutch and the second inclined slide disposed on the other side of the clutch.

[0018] Through the above technical solution, this application can save the force required for the clutch to rotate the bushing when the clutch drives the guide pin to move and the guide pin drives the bushing to rotate.

[0019] In some technical solutions, the drive disc assembly includes a third turntable, a clutch handle, a transmission assembly, a fourth turntable, a second reset component, a screw cap with a rotating shaft, and a nut, wherein...

[0020] The third turntable is provided with a first accommodating space.

[0021] The clutch handle includes a handle and a connecting structure. The handle is connected to the connecting structure, and a second accommodating space is provided within the connecting structure.

[0022] The transmission assembly is housed within the second accommodating space, the transmission assembly is connected to the synchronous belt, and the connecting structure is housed within the first accommodating space.

[0023] One side of the fourth turntable is connected to the third turntable, and the other side is used to connect to a support device that supports the object being supported.

[0024] The second reset component is housed within the first accommodating space, with one end connected to the third turntable and the other end connected to the connecting structure.

[0025] The cap is connected to the fourth turntable, and the rotating shaft passes through the third turntable, the transmission assembly, and the fourth turntable and is connected to the nut.

[0026] Through the above technical solution, this embodiment of the application houses both the transmission component and the connecting structure within the third turntable, making the overall structure of the drive disc assembly more compact and significantly reducing the volume of traditional drive disc assemblies. Furthermore, this embodiment of the application includes a handle, allowing the user to adjust the angle between the lifting arm and the upright with a single button, improving the flexibility of adjusting the angle between the lifting arm and the upright.

[0027] In some technical solutions, the third turntable is further provided with a first opening and a second opening, and the fourth turntable is provided with a first connecting plate and a second connecting plate. The first connecting plate is connected to one side of the third turntable, and the second connecting plate is connected to the other side of the third turntable. The first connecting plate covers the first opening. One end of the handle is connected to the connecting structure, and the other end extends outward from the third turntable through the second opening. The handle is slidably connected to the second opening.

[0028] When the handle is subjected to pressure and moves in the third direction through the second opening, the clutch handle drives the transmission assembly to rotate, the transmission assembly drives the synchronous belt to drive, and the synchronous belt drives the synchronous pulley to rotate, so as to realize the rotation of the clutch in the first direction.

[0029] When the pressure disappears, the handle is subjected to the elastic force of the second reset member and moves in the fourth direction through the second opening. The clutch handle drives the transmission assembly to rotate, the transmission assembly drives the synchronous belt to drive, and the synchronous belt drives the synchronous pulley to rotate, so as to realize the rotation of the clutch in the second direction.

[0030] Through the above technical solution, the clutch in this embodiment of the application is simultaneously subjected to the elastic force of the first reset component and the second reset component, which can effectively improve the stability of the meshing of the first gear plate and the second gear plate, as well as improve the stability of the clutch handle returning to its original position.

[0031] In some technical solutions, the transmission assembly includes three first driven wheels and two driven wheels. The second driven wheel is sleeved on the outer wall of the rotating shaft. The three first driven wheels are distributed in a triangle around the second driven wheel and mesh with the second driven wheel. The inner wall of the connecting structure is provided with a toothed structure, and each first driven wheel meshes with the connecting structure.

[0032] In some technical solutions, the timing belt portion is located inside the lifting arm.

[0033] In some technical solutions, the clutch-type cantilever bracket further includes a connecting assembly. The upright includes a column and a cantilever. The column is fixedly connected to the table clamp. One end of the cantilever is movably connected to the column through the connecting assembly, and the other end is connected to the lifting arm through the clutch disc assembly.

[0034] Through the above technical solution, the overall height of the clutch-type cantilever bracket can be adjusted to meet the user's height requirements.

[0035] In some technical solutions, the clutch-type cantilever bracket further includes a disc and a base. One side of the base is connected to the column, and the other side is connected to the table clamp. The disc is sleeved on the outer wall of the column and connected to the base.

[0036] In some technical solutions, the clutch-type cantilever bracket further includes a first decorative cover, a second decorative cover, and a third decorative cover, wherein the first decorative cover is connected to the first turntable, the second decorative cover is connected to the second turntable, and the third decorative cover is connected to the fourth turntable;

[0037] The first decorative cover is located on one side of the clutch disc assembly, and the second decorative cover is located on the other side of the clutch disc assembly;

[0038] The third decorative cover is located on one side of the drive disk assembly, and the screw cap is located on the other side of the drive disk assembly.

[0039] Through the above technical solution, the embodiments of this application can improve the aesthetics of the clutch-type cantilever bracket and have a dustproof effect, preventing dust from entering the first turntable, the second turntable, the third turntable and the fourth turntable.

[0081] It should be noted that, in this document, the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0082] The specific embodiments of this application will be further described below with reference to the accompanying drawings.

[0083] refer to Figure 1-17 As shown, this application embodiment provides a clutch-type cantilever bracket 1, including:

[0084] The table clamp 10, upright 20, lifting arm 30, clutch disc assembly 40, drive disc assembly 50, and synchronous belt 60 are provided. The table clamp 10 is used to fix the clutch-type cantilever bracket 1 to the table. One end of the upright 20 is connected to the table clamp 10, and the other end is connected to one side of the lifting arm 30 through the clutch disc assembly 40. The other side of the lifting arm 30 is connected to the drive disc assembly 50.

[0085] The clutch assembly 40 includes a first turntable 41 with a first gear 411, a through shaft 42 with at least a pair of guide pins 421, a bushing 43 with a second gear 431 and at least a pair of mounting holes 432, a clutch 44, a first reset member 45, and a second turntable 46. The first turntable 41 is connected to the upright 20. One end of the through shaft 42 is connected to the first turntable 41, and the other end is connected to the second turntable 46. The bushing 43 is sleeved on the outer side wall of the through shaft 42, and the clutch 44 is sleeved on the outer peripheral wall of the bushing 43. One end of the clutch 44... A first protruding structure 441 is provided, and a limiting groove 4411 is provided on the first protruding structure 441. A synchronous pulley 443 is provided at the other end of the clutch 44. At least one pair of inclined sliding grooves 442 are provided in the middle of the clutch 44. Each guide pin 421 passes through the corresponding mounting hole 432 and is slidably connected to the corresponding inclined sliding groove 442. The first reset member 45 is sleeved on the outer peripheral wall of the bushing 43. One end of the first reset member 45 is received in the limiting groove 4411, and the other end abuts against the side wall of the second gear plate 431. The second turntable 46 is connected to the lifting arm 30. Figure 3 , 5 As shown in numbers 6, 7, 8, 9, and 10;

[0086] The synchronous belt 60 is connected to the synchronous pulley 443, and the synchronous belt 60 is connected to the drive disk assembly 50. The drive disk assembly 50 is also used to connect to the support device that supports the supported object.

[0087] When the drive disc assembly 50 drives the synchronous belt 60, the synchronous belt 60 drives the clutch 44 to rotate in the first direction. Each guide pin 421 slides in the corresponding inclined groove 442 as the clutch 44 rotates, causing the bushing 43 to move towards the second turntable 46 and compress the first reset member 45, so that the second gear plate 431 separates from the first gear plate 411. At this time, the lifting arm 30 can be rotated upwards or downwards (see above / downward position). Figure 1 (as shown), to adjust the angle between the lifting arm 30 and the upright 20;

[0088] When the drive disk assembly 50 stops driving the synchronous belt 60, the bushing 43 is moved towards the first gear disk 411 by the elastic force of the first reset member 45. The bushing 43 drives the clutch 44 to rotate in the second direction through each guide pin 421 until the second gear disk 431 engages with the first gear disk 411. At this time, the clutch 44 is locked, and the angle between the lifting arm 30 and the upright 20 cannot be adjusted.

[0089] It should be noted that the table clamp 10 includes a table clamp angle iron 11, an adjustable bracket 12, a screw 13, a locking handle 14, a locking rubber sleeve 15, a first fastener 16, and a second fastener 17, as shown below. Figure 11 As shown, the table clamp angle iron 11 is L-shaped, and the table clamp angle iron 11 is provided with three sets of gourd holes 111 of different heights. The adjustable bracket 12 is fixedly connected to any set of gourd holes 111 through the first fastener 16. One end of the screw 13 is fixedly connected to the locking handle 14. The adjustable bracket 12 is provided with a first through hole 121. The other end of the screw 13 passes through the first through hole 121 and is fixedly connected to the locking rubber sleeve 15. The table clamp angle iron 11 is fixedly connected to the upright 20 through the second fastener 17.

[0090] More specifically, the table clamp angle iron 11 is fixedly connected to the upright 20 by four second fasteners 17.

[0091] The first fastener 16 is an external hexagonal screw.

[0092] The second fastener 17 is a flat-head screw.

[0093] When the table clamp 10 is clamped onto the table, the upper surface of the table is in contact with the clamping part 112 of the table clamp angle iron 11, and the lower surface of the table is in contact with one side of the locking rubber sleeve 15.

[0094] Depending on the thickness of the desktop, the user can adjust the position of the locking sleeve 15 to suit the corresponding application scenario. Specifically, rotating the locking handle 14 to the left moves the locking sleeve 15 closer to the clamping part 112; rotating the locking handle 14 to the right moves the locking sleeve 15 away from the clamping part 112 (please refer to [reference needed] for specific orientations). Figure 1 and Figure 2 ).

[0095] In this embodiment, the thickness of the tabletop held by the table clamp 10 ranges from 0 to 90 mm. In other embodiments, the thickness range can be set by those skilled in the art according to actual needs.

[0096] The height of the upright 20 is adjustable.

[0097] The lifting arm 30 includes a tubular arm 31 and multiple cable clamps 32, such as Figure 3 As shown, each of the line clips 32 is disposed on the tube arm 31, and the timing belt 60 is partially housed within the tube arm 31; one end of the tube arm 31 is connected to the second turntable 46, and the other end is connected to the drive disk assembly 50.

One end of the vertical pole 20 is connected to the table clamp 10, and the other end is connected to one side of the lifting arm 30 through the clutch disc assembly 40. The other side of the lifting arm 30 is connected to the drive disc assembly 50. The timing belt 60 is used to connect the drive disc assembly 50 and the clutch disc assembly 40. The drive disc assembly 50 is also used to connect a support device that supports the supported object. Thus, the clutch-type cantilever bracket 1 of this application embodiment can stably support the supported object. This embodiment of the application designs the clutch disc assembly 40 as including a first turntable 41 with a first toothed disc 411, a through shaft 42 with at least a pair of guide pins 421, a bushing 43 with a second toothed disc 431 and at least a pair of mounting holes 432, a clutch 44, a first reset member 45, and a second turntable 46. The first turntable 41 is connected to the upright 20, one end of the through shaft 42 is connected to the first turntable 41, and the other end is connected to the second turntable 46. The bushing 43 is sleeved on the outer side wall of the through shaft 42, and the clutch 44 is sleeved on the outer peripheral wall of the bushing 43. One end of the clutch 44 is provided with a first protrusion structure 441, on which a limit groove 4411 is provided, and the other end is provided with a synchronous pulley 443. At least a pair of oblique sliding grooves 442 are provided in the middle of the clutch 44. The guide pin 421 passes through the corresponding mounting hole 432 and is slidably connected to the corresponding inclined groove 442. The first reset member 45 is sleeved on the outer peripheral wall of the bushing 43. One end of the first reset member 45 is housed in the limiting groove 4411, and the other end abuts against the side wall of the second gear plate 431. The second turntable 46 is connected to the lifting arm 30. Thus, the drive disc assembly 50 can drive the synchronous belt 60 to drive the clutch 44 to rotate, thereby driving the bushing 43 to move, realizing the separation or engagement of the first gear plate 411 and the second gear plate 431. When the first gear plate 411 and the second gear plate 431 are separated, the included angle between the lifting arm 30 and the upright 20 can be adjusted. When the first gear plate 411 and the second gear plate 431 are engaged, the clutch 44 is locked, and the included angle between the lifting arm 30 and the upright 20 cannot be adjusted. Compared with the prior art of adjusting the angle between the lifting arm and the upright by bolts, the clutch disc assembly 40 used in this embodiment of the application achieves the separation and engagement of the first gear disc 411 and the second gear disc 431 by driving the guide pin 421 to slide in the inclined slide groove 442 through the clutch 44. This can effectively avoid the wear of the first gear disc 411 and the second gear disc 431, and also prevent slippage caused by the wear of the first gear disc 411 and the second gear disc 431. This allows the upright 20 to support the lifting arm 30 at a predetermined angle, thereby improving the stability of the upright 20 supporting the lifting arm 30 at a predetermined angle.
