Description

A clutch cantilever bracket Priority information

[0001] This application claims priority to Chinese invention patent application CN2023109569197, entitled "A Clutch Cantilever Bracket" and filed on July 31, 2023, the contents of which are incorporated herein by reference. Technical Field

[0002] The present invention relates to the technical field of supports, and more particularly to a clutch cantilever support. Background Art

[0003] A cantilever bracket is a bracket used to support audio and video equipment such as mobile phones, tablets, microphones or cameras. Its application scenarios include video shooting, video conferencing, live streaming, reading or gaming.

[0004] A traditional cantilever bracket includes a base, a vertical pole, a lifting arm, and a bolt. One end of the lifting arm is used to connect to a support device that supports the supported object, and the other end is provided with a first gear. One end of the vertical pole is fixedly connected to the base, and the other end is provided with a rotating joint with a second gear. The bolt passes through the first and second gear discs, allowing them to move axially, thereby switching the clutch state between the first and second gear discs. When the bolt is loosened, the first and second gear discs separate, and the user can rotate the lifting arm upward or downward to adjust the angle between the lifting arm and the vertical pole. When the bolt is tightened, the first and second gear discs fit tightly and engage with each other, fixing the lifting arm to the vertical pole. The angle between the lifting arm and the vertical pole cannot be adjusted. This cantilever bracket adjusts the angle between the lifting arm and the vertical pole by tightening and loosening the bolt. Because bolts are threaded fasteners, after repeated tightening and loosening, the outer surface of the bolts and the connection points between the first and second gear discs become severely worn. This causes the bolts to slip during tightening, preventing the first and second gear discs from engaging, and preventing the vertical pole from supporting the lifting arm at the predetermined angle. Furthermore, tightening and loosening the bolts is cumbersome, making them inconvenient to use. SUMMARY OF THE INVENTION Technical issues

[0005] One purpose of the embodiments of the present application is to solve the above problems and provide corresponding beneficial effects.

[0006] Another object of the embodiments of the present application is to provide a clutch cantilever bracket, which solves the technical problem of how to improve the stability of the vertical pole supporting the lifting arm according to a predetermined angle, and improve the ease of use of the clutch cantilever bracket. Technical Solutions

[0007] The embodiment of the present application is mainly implemented through the following technical solutions: The embodiment of the present application provides a clutch cantilever bracket, including:

[0008] A table clamp, a vertical pole, a lifting arm, a clutch disk assembly, a drive disk assembly, and a synchronous belt. The table clamp is used to fix the clutch cantilever bracket on the table. 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 through the clutch disk assembly. The other side of the lifting arm is connected to the drive disk assembly.

[0009] The cam is secured to a position 52° to the first gear and secured to the second gear of the driver having a first end connected to the first gear and a second end connected to the second gear of the driver having a first end connected to the first gear.

[0010] The synchronous belt is connected to the synchronous pulley, and the synchronous belt is connected to the driving disc assembly, and the driving disc assembly is also used to connect to a supporting device that supports the supported object;

[0011] When the driving disc assembly drives the synchronous belt transmission, the synchronous belt drives the clutch to rotate in the first direction, and each guide pin slides in the corresponding inclined slot as the clutch rotates, driving the shaft sleeve to move toward the second turntable and compressing the first reset member to separate the second gear disc from the first gear disc. At this time, the lifting arm can be rotated upward or downward to adjust the angle between the lifting arm and the vertical pole;

[0012] When the driving disc assembly stops driving the synchronous belt transmission, the sleeve is acted upon by the elastic force of the first reset member and moves toward the first gear disc. The sleeve drives the clutch to rotate in the second direction through each guide pin until the second gear disc engages with the first gear disc. At this time, the clutch is locked and the angle between the lifting arm and the vertical pole cannot be adjusted.

[0013] A clutch cantilever bracket provided in an embodiment of the present application includes a table clamp, a vertical pole, a lifting arm, a clutch disk assembly, a drive disk assembly and a synchronous 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 through the clutch disk assembly. The other side of the lifting arm is connected to the drive disk assembly. The synchronous belt is used to connect the drive disk assembly and the clutch disk assembly. The drive disk assembly is also used to connect a supporting device that supports the supported object. Therefore, the clutch cantilever bracket in an embodiment of the present application can stably support the supported object. The embodiment of the present application designs the clutch disc assembly to include a first rotating disc with a first gear disc, a through shaft with at least a pair of guide pins, a sleeve with a second gear disc and at least a pair of mounting holes, a clutch, a first reset member and a second rotating disc, the first rotating disc is connected to the vertical rod, one end of the through shaft is connected to the first rotating disc, the other end is connected to the second rotating disc, the sleeve is sleeved on the outer wall of the through shaft, the clutch is sleeved on the outer peripheral wall of the sleeve, one end of the clutch is provided with a first protrusion structure, a limiting groove is provided on the first protrusion structure, the other end is provided with a synchronous pulley, the middle part of the clutch is provided with at least a pair of inclined grooves, each guide pin is provided with a first gear disc, and the second gear disc is provided with a first reset member. The cam is secured to the outer wall of the second gear and is secured to the second end of the shaft when the cam is engaged. Compared with the existing technology of adjusting the angle between the lifting arm and the vertical pole by bolts, the clutch disc assembly adopted in the embodiment of the present application realizes the separation and engagement of the first gear disc and the second gear disc by driving the guide pin in the inclined slide groove by the clutch, which can effectively avoid the wear of the first gear disc and the second gear disc, and can also prevent slipping caused by the wear of the first gear disc and the second gear disc, so that the vertical pole can support the lifting arm according to the predetermined angle, thereby improving the stability of the vertical pole supporting the lifting arm according to the predetermined angle.

[0014] The clutch-type cantilever bracket of the present application is easy to operate. Pressing the clutch handle can adjust the height and position to the desired position, and releasing the clutch handle can stop at any position. In other words, one-touch adjustment can easily and flexibly adjust the lifting arm without friction resistance and labor-saving operation.

[0015] In the embodiment of the present application, a table clamp is used to fix the clutch cantilever bracket on the desktop. The table clamp has a wide adaptability and clamping range and is stable and reliable, which is conducive to increasing the application scenarios of the clutch cantilever bracket.

[0029] When the handle is moved toward the third direction by the pressure acting on the second opening, the clutch handle drives the transmission assembly to rotate, the transmission assembly drives the synchronous belt, and the synchronous belt drives the synchronous pulley to rotate, so as to realize the rotation of the clutch toward the first direction;

[0030] When the pressure disappears, the handle is acted upon by the elastic force of the second reset member and moves in the fourth direction at the second opening.
