[0039] Figures 1 to 4The self-locking mechanism 10 in some embodiments of the utility model is shown, and the self-locking mechanism 10 can be self-locked and unlocked when needed. The self-locking mechanism 10 includes a fixing device 1, a mounting device 2 and a connecting device 3. The fixing device 1 is used to support the mounting device 2. The mounting device 2 is used to install a sound pickup structure and / or a sound speaker structure. The connecting device 3 is used to connect the fixing device 1 and the mounting device 2.

[0040] like Figures 1 to 4 As shown, the fixing device 1 is provided with a disassembly position 11. It is understandable that the disassembly position 11 can be configured to be defined by a hole, a groove or a structure with a certain protrusion relative to the fixing device 1, or it can be configured to simply refer to a partial position of a certain surface of the fixing device 1.

[0041] like Figures 1 to 4 As shown, the installation device 2 includes a bracket 21 and a disassembly frame 22 , and the disassembly frame 22 is connected to the bracket 21 .

[0042] It can be understood that the sound pickup structure and / or the sound speaker structure can be configured to be arranged between the bracket 21 and / or the disassembly frame 22. The bracket 21 and the disassembly frame 22 can be configured to be fixedly connected or movably connected, and the movable connection can be a sliding connection or a rotating connection, depending on the design and use requirements. The disassembly frame 22 is used to be connected to the disassembly position 11.

[0043] like Figures 4 to 7 As shown, the connecting device 3 includes a movable limiting assembly 31, a movable part 32 and a resilient part 33. The movable limiting assembly 31 includes a limiting structure 311 and a clamping position 312. One of the limiting structure 311 and the clamping position 312 is arranged on the fixing device 1, and the other of the limiting structure 311 and the clamping position 312 is arranged on the disassembly and assembly frame 22. The limiting structure 311 is used to define the movable position 20. The movable part 32 is movably arranged at the movable position 20. The resilient part 33 is arranged in the disassembly and assembly frame 22, and the resilient part 33 is drivingly connected to the movable part 32.

[0044] It can be understood that the movable limiting assembly 31 plays a role in guiding the movable member 32. The limiting structure 311 is used to define the movable position 20. The movable position 20, on the one hand, provides the required space for the movable member 32 to move, and on the other hand, can also play a role in guiding or limiting the movable member 32 to a certain extent. The clamping position 312 is used for the movable member 32 to be clamped accordingly. The movable member 32 is provided with a portion that can be clamped with the clamping position 312. The elastic member 33 is used to provide a corresponding elastic force to the movable member 32. The movable member 32 can always have a tendency to move in a predetermined direction under the elastic force of the elastic member 33, so that the movable member 32 can be clamped in the clamping position 312 accordingly.

[0045] It should be noted that the clamping position 312 can be a hole or a groove, or a protrusion structure; accordingly, the movable part 32 can be provided with a protrusion, a groove or a hole according to the specific structure of the clamping position 312 to adapt to the clamping position 312 for clamping.

[0046] Please also read Figures 1 to 7 When the disassembly frame 22 is assembled at the disassembly position 11, the movable part 32 is configured to be clamped at the clamping position 312 under the drive of the elastic member 33, thereby limiting the relative position of the disassembly frame 22 and the fixing device 1; the movable part 32 is also configured to be able to overcome the elastic force of the elastic member 33 and move out of the clamping position 312, thereby unlocking the disassembly frame 22 and the fixing device 1.

[0047] It can be understood that during the process of assembling the disassembly frame 22 corresponding to the disassembly position 11, the clamping position 312 will gradually align with the movable part 32; when the disassembly frame 22 is assembled to the predetermined position, the movable part 32 will move under the drive of the elastic member 33, so that the movable part 32 and the clamping position 312 are clamped and matched, thereby achieving the purpose of limiting the relative position of the disassembly frame 22 and the fixing device 1, that is, completing the assembly connection between the disassembly frame 22 and the fixing device 1.

[0048] When the movable part 32 is in a clamping fit with the clamping position 312, the movable part 32 can be operated to overcome the elastic force of the elastic part 33 to move, so that the movable part 32 is released from the clamping position 312, and the disassembly frame 22 can be removed from the fixing device 1, that is, the purpose of disassembling and separating the installation device 2 from the fixing device 1 is achieved.

[0049] In some embodiments, the elastic member 33 may be configured as a spring, a spring sheet or an elastic rubber.

[0050] like Figures 4 to 7 As shown, in some embodiments of the self-locking mechanism 10 , the limiting structure 311 includes a rotating shaft 3111 , the rotating shaft 3111 is disposed on the disassembly and assembly frame 22 or the fixing device 1 , and the movable member 32 is rotatably disposed on the rotating shaft 3111 .

[0051] It can be understood that in this type of embodiment, the movable direction of the movable member 32 is rotation. The rotating shaft 3111 is used to support the movable member 32 to rotate, and the elastic force of the elastic member 33 is used to drive the movable member 32 to rotate in a certain direction.

[0052] It should be noted that the connection methods between the movable part 32 and the rotating shaft 3111 include direct connection and indirect connection. The direct connection can be configured as the rotating shaft 3111 passing through the movable part 32, and the indirect connection can be configured as the movable part 32 is connected to the rotating shaft 3111 through other intermediate elements. Of course, other rotational connection methods in the prior art can also be used.

[0053] In some embodiments, the movable part 32 can be configured to be completely exposed outside the disassembly and assembly frame 22, or can be configured to be partially exposed outside the disassembly and assembly frame 22, depending on the design and use requirements of the product.

[0054] like Figure 6 and Figure 7 As shown, in some embodiments of the self-locking mechanism 10 , the limiting structure 311 further includes a limiting groove 3112 , the limiting groove 3112 defines the movable position 20 , and the movable member 32 is located in the limiting groove 3112 .

[0055] It can be understood that the limiting groove 3112 serves to limit the movable member 32, so that the movable member 32 can only move under the limitation of the groove wall of the limiting groove 3112, thereby preventing the movable member 32 from falling out.

[0056] It should be noted that the movable member 32 can be further configured as a rotational connection or a sliding connection. Regardless of the movable mode of the movable member 32, the position or sliding direction of the movable member 32 can be limited by the limiting groove 3112 to ensure that the movable member 32 can be accurately clamped and released in time when needed.

[0057] Further, the width of the limiting groove 3112 can be configured to match the width of the movable member 32. In this way, it is possible to avoid forming an excessively large interval between the limiting groove 3112 and the movable member 32, and the movement of the movable member 32 is more effectively limited.

[0058] like Figures 4 to 7 As shown, in some embodiments of the self-locking mechanism 10, a avoidance hole 3113 is opened in the limit groove 3112, and the avoidance hole 3113 is configured to be aligned with the clamping position 312 when the disassembly frame 22 is assembled at the disassembly position 11, so that the avoidance hole 3113 is for the movable part 32 to pass through and be clamped at the clamping position 312.

[0059] It can be understood that in various embodiments where the movable part 32 is built into or partially built into the disassembly and assembly frame 22, the opening of the avoidance hole 3113 can further provide the movable part 32 with corresponding movement space, thereby preventing the side walls and other elements of the movable part 32 from hindering or affecting the movement of the movable part 32, and ensuring that the movable part 32 can be accurately positioned and clamped.

[0060] like Figures 4 to 7 As shown, in some embodiments of the self-locking mechanism 10, the limiting structure 311 is disposed on the disassembly frame 22, and the clamping position 312 is disposed on the fixing device 1;

[0061] The movable part 32 is provided with a key arm 321, a key cap 322 and a snap protrusion 323. One end of the key arm 321 is connected to the movable part 32, and the other end of the key arm 321 is penetrated by a avoidance hole 3113 and connected to the key cap 322. The snap protrusion 323 is configured to be removably snapped at the snapping position 312 under the drive of the movable part 32.

[0062] It can be understood that the key arm 321 is used to connect the key cap 322 and the movable part 32. The shape of the key cap 322 can be flexibly set, as long as the user can drive the movable part 32 to move in a predetermined direction through the key cap 322 and the key arm 321. The buckle protrusion 323 is used to form a clamping fixation after being abutted against the clamping position 312. If the clamping position 312 is configured as a hole or a groove, the buckle protrusion 323 is correspondingly inserted into the hole or the groove to complete the corresponding clamping; if the clamping position 312 is configured as a convex structure, the buckle protrusion 323 is configured to be able to clamp the convex structure accordingly.

[0063] like Figures 4 to 7 As shown, in some embodiments of the self-locking mechanism 10, the limiting structure 311 is arranged on the disassembly and assembly frame 22, and the clamping position 312 is arranged on the fixing device 1; it can be understood that the movable part 32 in this type of embodiment is also correspondingly arranged on the disassembly and assembly frame 22.

[0064] A through hole 111 connected to the movable position 20 is provided on the disassembly and assembly frame 22, and the connecting device 3 also includes a plug 34. A positioning portion 324 is provided on the movable member 32, and the plug 34 is screwed to the through hole 111. One end of the elastic member 33 is sleeved on the positioning portion 324, and the other end of the elastic member 33 is supported on the plug 34.

[0065] It can be understood that the through hole 111 is used for installing the plug 34 and the elastic member 33. After the assembly is completed, the elastic member 33 will be confined between the plug 34 and the positioning portion 324. The elastic member 33 is sleeved on the positioning portion 324, which can prevent the elastic member 33 from positional displacement or irresistible deformation to a certain extent.

[0066] In some embodiments of the self-locking mechanism 10 , the limiting structure 311 includes a sliding groove, and the movable member 32 is slidably disposed in the sliding groove. The movable member 32 is configured to be detachably clamped at the clamping position 312 when sliding along the sliding groove.

[0067] It can be understood that in this type of embodiment, the movable member 32 is configured as a sliding connection, that is, the movable member 32 is configured to be able to slide along the sliding groove. The movable member 32 can slide along the sliding groove under the elastic force of the elastic member 33 and the operation of the user, thereby achieving the locking and separation of the movable member 32 and the locking position 312.

[0068] like Figure 3 and Figure 4As shown, in some embodiments of the self-locking mechanism 10 , the bracket 21 is rotatably connected to the disassembly frame 22 .

[0069] It is understandable that the bracket 21 and the disassembly frame 22 can be rotatably connected via a rotating shaft, or can be connected via a common rotatable connection structure in the related art. The rotatable connection method allows the user to adjust the direction of the bracket 21 according to the use requirements.

[0070] like Figures 1 to 4 as well as Figure 6 As shown, in some embodiments of the self-locking mechanism 10 , the fixing device 1 includes a base 12 , and the disassembly position 11 is disposed on the base 12 .

[0071] It can be understood that the base 12 plays a supporting and fixing role. The disassembly position 11 can be a groove, a hole or a channel, and can also be configured to refer to a certain plane on the base 12.

[0072] In some embodiments of the self-locking mechanism 10 , the fixing device 1 includes a base 12 and a clamping mechanism, the disassembly and assembly position 11 is disposed on the base 12 , and the clamping mechanism is disposed on the base 12 .

[0073] It can be understood that the clamping mechanism is used to drive the base 12 to clamp and fix. The clamping mechanism can be a common structure in the prior art that can be used for clamping and fixing.

[0074] like Figures 4 to 6 As shown, the cross section of the disassembly frame 22 is rectangular, and the contour of the disassembly position 11 is adapted to the disassembly frame 22 .

[0075] It can be understood that through the contents of this type of embodiment, the corner positions of the disassembly and assembly frame 22 can correspond to the contour of the clamping limit at the disassembly and assembly position 11, which not only plays a positioning role but also plays a role in guiding the installation, thereby preventing the installation device 2 from deflecting on the fixing device 1 and ensuring that the movable part 32 can accurately align with the clamping position 312.

[0076] Figure 6 The microphone 30 in some embodiments of the present invention is shown. The microphone 30 includes a self-locking mechanism 10 and a sound pickup mechanism 40 . The sound pickup mechanism 40 is arranged on the fixing device 1 .

[0077] It can be understood that the sound pickup mechanism 40 can be a common structure in the prior art that can be used for microphone sound pickup. Through the provision of the self-locking mechanism 10, the sound pickup mechanism 40 on the mounting device 2 can be quickly disassembled, which improves the convenience of repairing some parts of the microphone, and the product can replace a certain part separately according to different usage requirements, which improves the scalability of the microphone in actual use.

[0078] The speaker of the utility model comprises a self-locking mechanism 10 and a speaker mechanism, and the speaker mechanism is arranged on the fixing device 1 .

[0079] It can be understood that, by providing the self-locking mechanism 10, the speaker mechanism on the mounting device 2 can be quickly disassembled and separated from the fixing device 1, thereby improving the convenience of disassembly, assembly and maintenance of the speaker, and also improving the scalability of the actual use of the speaker.

[0080] The implementation of this utility model has the following beneficial effects:

[0081] The utility model relates to a self-locking mechanism, a microphone and a speaker, both of which are provided with a self-locking mechanism. The self-locking mechanism enables a disassembly frame to be correspondingly assembled to a fixing device by opening a disassembly position. Furthermore, by setting a movable limit assembly, a movable part and an elastic part, when the disassembly frame is correctly aligned and assembled at the disassembly position, the elastic part can be used to quickly drive the movable part to clamp in the clamping position, quickly lock the relative position between the disassembly frame and the fixing device, and at the same time, the user can operate the movable part to move out of the clamping position, so that the disassembly frame can be removed from the fixing device;

[0082] In this way, the installation device and the fixing device are detachable, thereby improving the maintenance convenience of the product, and also allowing the installation device or the fixing device to be updated or replaced separately, thereby improving the scalability of the product in actual use.
