Description

Technical Field

[0001] This invention relates to the field of mechanical parts technology, specifically to microphone stands, and particularly to a quick-release device for a microphone stand. Background Technology

[0002] Microphones, also known as microphones, are common tools in work and daily life. To free up your hands when using a microphone, a microphone stand is usually needed to fix it in the desired position. Currently, there are many types of microphone stands to meet the needs of different people in different situations, such as floor-standing microphone stands and cantilever microphone stands that are suspended from a tabletop by clips. The connection between the microphone stand's arm and base, or between the stand and the arm, is mostly adjusted or tightened with screws, requiring tools for adjustment, which is inconvenient and tools are easy to lose. In addition, the connection between the microphone head and the microphone is usually that the microphone is directly screwed into the threaded connector at the front of the microphone stand's arm, or a modular quick-release connector is used for component quick release, but this has the problems of complex mechanism, inconvenient operation, low installation efficiency, and certain risks such as the microphone falling off. Summary of the Invention

[0003] The purpose of this invention is to provide a quick-release device for a microphone stand, based on existing technology.

[0004] To achieve the above objectives, a first aspect of the present invention provides a quick-release device for a microphone stand, comprising:

[0050] The following disclosure provides many different embodiments or examples to illustrate different components of embodiments of the present invention. Specific examples of the components and their arrangement will be disclosed below to simplify the description of this disclosure. Of course, these specific examples are not intended to limit this disclosure.

[0051] like Figures 1 to 9 The image shows an embodiment of the microphone stand provided by the present invention. In this embodiment, the microphone stand, Design Arm ProFlex, uses two quick-release mechanisms, namely, as shown... Figures 1 to 5 The quick-release device at the connection shown, and as shown Figures 6 to 9 The head quick-release mechanism is shown. Light sources can also be added to the microphone stand to enhance lighting effects; this is a microphone stand with lights, the Design Arm ProFlex RGB.

[0052] like Figure 1 As shown, the microphone stand provided by this invention includes a support arm 1, a crossbar 2, a column, and a base. The head of the support arm 1 is equipped with a quick-release device 6 for connecting the microphone. One end of the crossbar 2 is connected to the lower joint of the support arm 1 via a quick-release device 3, and the other end of the crossbar 2 is connected to the upper end of the column via a quick-release device 4. The lower end of the column is connected to the base via a quick-release device 5. The quick-release device of this invention is particularly suitable for rapid vertical connections. The quick-release device and microphone stand provided by this invention are also applicable to monitor stands, etc.

[0053] by Figure 1 The quick-release device 5 at the connection point will be used as an example for explanation. Figures 2 to 5 As shown, the quick-release device for the connection of the present invention is specifically illustrated.

[0054] The quick-release device 5 includes: a fixed shaft 53 for connecting to the first connecting body of the microphone bracket, in this embodiment, the first connecting body of the microphone bracket is a column 51; and a bushing 57, fitted inside the second connecting body of the microphone bracket, in this embodiment, the second connecting body of the microphone bracket is the upper end 52 of the base. Besides the embodiment provided by this invention, the quick-release device can be flexibly configured in different positions. For example, the first connecting body can be a crossbar, and the second connecting body can be a column, enabling a quick connection between the crossbar and the column; the first connecting body can be a support arm, and the second connecting body can be a crossbar or a base, enabling a quick connection between the support arm and the crossbar or base.

[0055] like Figure 4 and 5 As shown, the bushing 57 can be fixed inside the upper end 52 of the base by means of a limiting block-limiting groove, forming a stable assembly relationship. The fixed shaft 53 is fitted inside the bushing 57 by a rotary lock assembly. The rotary lock assembly includes a lock body 55 and a rotating ring 54 rotatably fitted outside the lock body 55. By adjusting the rotating ring 54 to the corresponding position, locking and unlocking are achieved.

[0056] Specifically, the lock body 55 is a ring-shaped body, and the lock body 55 is disposed at the end of the bushing 57, such as... Figure 4 As shown, the lock body 55 is provided with four elastic locking blocks 58, which are distributed circumferentially along the lock body 55. Each elastic locking block 58 has a fixed end and a free end 59 opposite to the fixed end. The fixed end to the free end of each elastic locking block 58 extends circumferentially along the lock body. The fixed end of the elastic locking block is connected to the lock body 55. The inner side of the rotating ring 54 is provided with a protrusion 50 that cooperates with the elastic locking blocks 58. By rotating the rotating ring 54, the locking and unlocking states of the rotary lock assembly are changed. Figure 5 In the locked state, the protrusion 50 pushes the free end 59 of the elastic block toward the fixed shaft 53 towards the radial center of the bushing 57, and the free end 59 of the elastic block is offset relative to the fixed end of the elastic block, that is, it deviates from the circumference of the lock body; in the unlocked state, the protrusion 50 moves away from the free end 59 of the elastic block, and the fixed shaft can freely enter and exit the bushing.

[0057] The fixed shaft 53 is provided with a positioning groove 56, which surrounds the fixed shaft 53 circumferentially. Figure 5 In the locked state shown, the free end 59 of the elastic block is located in the positioning groove 56 of the fixed shaft.

[0058] like Figure 4 As shown, the protrusion 50 is an arc-shaped protrusion, and the surface of the free end 59 of the elastic block facing the rotating ring 54 is concave to match the protrusion 50 for easy fitting.

[0059] like Figure 4 As shown, the lock body 55 is provided with a through groove extending circumferentially along the lock body, and the elastic block 58 is provided in the corresponding through groove, with the fixed end of the elastic block 58 connected to the inner side wall of the through groove.

[0060] The lock body 55 has a boss extending radially outward from the bottom and surrounding the lock body circumferentially. The boss matches the second connector of the microphone bracket.

[0061] The outer surface of the rotating ring 54 is provided with friction texture and markings for indicating the locked and unlocked positions.

[0062] The quick-release device at the connection point in this embodiment can be easily, simply, and reliably locked and unlocked by rotating the rotating ring after the parts to be connected are assembled in place, without the need for tools. It is also universally applicable to bases, columns, and any similar joints. Furthermore, it is very stable and not easy to loosen when locked.

[0063] by Figure 1 The following explanation will be based on the quick-release device 6 in the head section. Figures 6 to 9 As shown, the quick-release head device of the present invention is specifically illustrated.

[0064] The quick-release headgear 6 includes: a first connecting block having a first end and a second end distributed axially; the first end being used to connect to a third connecting body of a microphone bracket; in this embodiment, the third connecting body of the microphone bracket is the upper end of the support arm 1; a slot 62 is provided on the end surface of the second end, the slot 62 having an upper opening; the first connecting block having a shaft hole; and a rivet 65 passing through the shaft hole to fix the first connecting block to the third connecting body of the microphone bracket; and a second connecting block 60 for connecting to a microphone; the end surface of the second connecting block... A protrusion 63 is provided, which engages with the slot 62 through its upper opening. A retaining ring 61, cylindrical in shape, is movably fitted around the outside of the first connecting block. By moving the retaining ring 61, the slot 62 can be exposed or covered. When the slot 62 is exposed, the protrusion 63 of the second connecting block can freely move in and out of the slot 62. When the retaining ring 61 covers the slot 62, the second connecting block is locked inside the first connecting block, preventing the second connecting block and the microphone on it from detaching from the first connecting block.

[0065] In the embodiments provided by the present invention, the microphone is securely and quickly fixed to the first connecting block at the head of the support arm by the second connecting block. When the microphone needs to be installed, the fixing ring 61 is pressed against the support arm to expose the slot, and the second connecting block is inserted downward into the slot to achieve quick installation. When the microphone needs to be removed, the fixing ring 61 is pressed against the support arm to expose the slot, and the second connecting block is lifted upward to remove the microphone installed on the second connecting block.

[0066] like Figure 8As shown, the retaining ring 61 can be elastically reset and moved via the elastic element 64. One end of the elastic element 64 is disposed on the retaining ring 61, and the other end is disposed on the first connecting block. After the compressed elastic element 64 is released, the retaining ring 61 can automatically reset due to the elastic force of the elastic element 64. In this embodiment, the elastic element 64 is a compression spring. The retaining ring 61 resets under the action of elastic force, covering the slot position and preventing the second connecting block and the microphone on it from detaching from the first connecting block.

[0067] like Figure 7 and 8 As shown, the inner wall of the fixing ring 61 is provided with a sliding groove, and the outer surface of the first connecting block is provided with a matching slider. The slider can slide in the sliding groove, which facilitates the movement of the fixing ring.

[0068] like Figure 7 and 9 As shown, the second connecting block includes a pair of fixing blocks 67 and a universal ball joint 66 clamped between the pair of fixing blocks 67. The universal ball joint 66 is provided with a connector for connecting a microphone. The clamping force between the pair of fixing blocks 67 is adjusted by a screw knob. The screw knob includes a threaded knob 68 and a screw 69. The fixing blocks are provided with protrusions, and the protrusions of the pair of fixing blocks 67 form the protrusion 63.

[0069] The quick-release head assembly of this embodiment can be modularly assembled. First, the microphone is connected to the second connecting block, and then the second connecting block is snapped into the head of the microphone bracket forearm, which enables quick assembly and disassembly. It is no longer necessary to hold the microphone and rotate it at the connection point. In addition, the fixing ring acts as a self-locking device to prevent the microphone from falling off due to accidental detachment during use and adjustment.

[0070] In addition to the embodiments provided by the present invention, it can also be modified into a microphone stand that only uses the quick-release device at the connection point, or a microphone stand that only uses the quick-release device at the head.

[0071] The quick-release device of the microphone bracket of the present invention allows for easy, simple and reliable locking and unlocking of the connection points after assembly, using a rotatable ring without the need for tools. It is also compatible with bases, columns and any similar joints. The quick-release head is very stable in the locked state, preventing accidental detachment and microphone drop during use and adjustment.

[0072] In this specification, the invention has been described with reference to specific embodiments thereof. However, it will be apparent that various modifications and variations can be made without departing from the spirit and scope of the invention. Therefore, the specification and drawings should be considered illustrative rather than restrictive.
