DETAILED DESCRIPTION

[0036] The technical scheme in the embodiments of the utility model will be described clearly and completely below, obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0037] In the field of mechanical connection, threaded connection is widely applied due to its simple structure, convenient assembly and disassembly and other advantages. However, the traditional threaded connection has the defect of unfixed rotation angle, when the two connected parts are non-circular special-shaped structures (such as polygonal prism), the difference of rotation angle will cause the side surface of the part to be unable to align, and further cause the following problems:

[0038] Unattractive appearance: the side surface misalignment of the polygonal prism affects the overall visual unity;

[0039] Reduced structural strength: misalignment may cause stress concentration and reduce the connection stability;

[0040] Inconvenient use: for example, handheld devices are difficult to hold due to side surface misalignment, or microphones and other devices are prone to rolling when placed.

[0041] In the prior art, for the positioning problem of threaded connection, part of the solutions use additional positioning pins or complex structures, but there are high cost, assembly is complicated, easy to damage and other disadvantages. For example, the positioning pin needs to be additionally processed with a hole position, increasing the manufacturing cost; if the traditional buckle structure is arranged near the end face, it is easy to be broken in the butt joint process due to misoperation. Therefore, in the production and development process, the above technical problems are improved, and a positioning structure for preventing misplacement is developed, and the specific implementation manner is as follows:

[0042] Please refer to Figures 1 to 8 In the embodiment of the utility model, a positioning structure for preventing misplacement, comprising a first component 10, a second component 20 and a positioning device 30, the first component 10 and the second component 20 are detachably fixedly connected, the positioning device 30 is provided with a positioning buckle 31 and a positioning groove 33, the positioning groove 33 is fixedly connected to the first component 10, the positioning buckle 31 is fixedly connected to the second component 20, or the positioning groove 33 is fixedly connected to the second component 20, the positioning buckle 31 is fixedly connected to the first component 10, and the positioning buckle 31 and the positioning groove 33 are matched with each other to form a separable buckling connection, so as to lock the positional relationship between the first component 10 and the second component 20.

[0043] Specifically, threaded connection is a widely used detachable fixed connection, which has the advantages of simple structure, reliable connection, convenient assembly and disassembly. When connected, the connection is realized by the rotation between the external thread 11 and the internal thread 21, and a certain pre-tightening force is generated, the friction torque between the threads is generated by the pre-tightening force, and the loosening is prevented. But threaded connection also has some defects, such as the angle after rotation is not fixed, the rotation torque applied during rotation is different, and the angle after rotation is also different.

[0044] Secondly, when both components using threaded connection are circular, or one of the components is circular, the situation that the angle after rotation is different is not obvious, but when both components are non-circular special-shaped structures, the angle after rotation is different, which causes the angle between the two components to be not uniform, so that the side surfaces cannot be aligned, which affects the appearance in vision and the quality due to misplacement, and is not convenient to use.

[0045] In addition, even if the components are circular, some components may be provided with patterns or special shapes, and if they are not aligned, the appearance will also be affected. For example, the net head 41 usually has some marks, trademark patterns and the like, if there is no positioning, it is easy to rotate insufficiently or excessively during rotation, which causes the marks to be not aligned, affecting the user's visual perception. In the prior art, the angle can only be fixed by using glue or screws, which is not convenient for assembly and has high cost.

[0046] Therefore, the positioning buckle 31 and the positioning groove 33 are arranged at the positions where the first component 10 and the second component 20 are connected with each other respectively, so that a preset positional relationship is formed between the first component 10 and the second component 20, and the first component 10 and the second component 20 have a positioning function when being connected. The first component 10 and the second component 20 are locked in the positional relationship, especially in the angular relationship, by the buckling connection between the positioning buckle 31 and the positioning groove 33, so that the side surfaces are kept in an aligned state, the aesthetic level is improved, the structural strength is enhanced, and the use is facilitated.

[0047] As shown in Figure 1 , preferably, the first component 10 and the second component 20 are respectively provided in a multi-prism structure. One end of the first component 10 is provided with an external thread 11, and the positioning groove 33 is arranged at the external thread 11. One end of the second component 20 is provided with an internal thread 21, and the positioning buckle 31 is arranged at the internal thread 21. The first component 10 and the second component 20 are connected by the thread connection to form a detachable fixed connection, and the positioning buckle 31 and the positioning groove 33 are matched with each other to keep the corresponding side surfaces of the first component 10 and the second component 20 in a coplanar state.

[0048] Specifically, when the first component 10 and the second component 20 are both provided in a multi-prism shape with the same number of side surfaces, if the angular relationship of the two is not locked, the side surfaces of the two are prone to be misaligned in the circumferential direction, which is not only not aesthetic but also affects the structural strength, especially the handheld use. However, through the positioning effect of the positioning buckle 31 and the positioning groove 33, the misalignment of the side surfaces of the two can be prevented, and the two are locked at a preset angle, so that the corresponding side surfaces can be kept in a coplanar state, facilitating the handheld use.

[0049] As shown in Figure 1 and Figure 4 , preferably, the positioning buckle 31 is arranged at the internal thread 21 away from the end surface of the second component 20, and the positioning groove 33 is arranged at the position of the external thread 11 of the first component 10 corresponding to the positioning buckle 31.

[0050] Specifically, the internal thread 21 extends a certain number of turns along the axial direction from the end surface of the arrangement end, which is equivalent to the positioning buckle 31 being arranged at the innermost position of the internal thread 21. This prevents the positioning buckle 31 from being arranged too close to the end surface and being easily broken by misoperation or other accidents during the initial abutting process of the first component 10 and the second component 20.

[0051] Secondly, the positioning buckle 31 can also be directly arranged at the last turn of the internal thread 21, so that when the thread connection is screwed to the last turn, the positioning buckle 31 and the positioning groove 33 are buckled and connected to form a positioning effect, which can not only make the screwing between the internal thread 21 and the external thread 11 tight but also position the final screwing angle.

[0052] In addition, the positioning groove 33 is just an inwardly recessed pit, and will not be broken, so it can be arranged at the starting thread of the outer thread 11 of the first assembly 10. At the starting thread of the outer thread 11, it corresponds to the last thread of the inner thread 21 when the screw connection is made.

[0053] As shown in Figure 2 Preferably, the first assembly 10 and the second assembly 20 are respectively provided in a polygonal structure, one end of the first assembly 10 is provided with an outer thread 11, and the positioning buckle 31 is arranged at the outer thread 11; one end of the second assembly 20 is provided with an inner thread 21, and the positioning groove 33 is arranged at the inner thread 21; the first assembly 10 and the second assembly 20 are connected by thread to form a detachable fixed connection, and the positioning buckle 31 and the positioning groove 33 are matched with each other to keep the corresponding side surfaces of the first assembly 10 and the second assembly 20 in a coplanar state.

[0054] Specifically, in another embodiment, the positioning buckle 31 can also be arranged at the outer thread 11, and the positioning groove 33 can also be arranged at the inner thread 21, as long as the arrangement positions of the positioning buckle 31 and the positioning groove 33 are matched with each other, so that the positioning function is realized during the screwing of the outer thread 11 and the inner thread 21. Preferably, when the screwing is basically completed, a certain pre-tightening force is generated between the threads, and the corresponding side surfaces of the first assembly 10 and the second assembly 20 are kept in a coplanar state, the positioning buckle 31 is just buckled in the positioning groove 33, thereby realizing the preset positioning function.

[0055] Secondly, it can be understood that the first assembly 10 and the second assembly 20 here do not represent the assembly sequence and do not constitute a limitation. For example, the first assembly 10 can be provided with an outer thread 11, the second assembly 20 can be provided with an inner thread 21, and they can be butted against each other to form a thread connection. The first assembly 10 can be provided with an inner thread 21, and the second assembly 20 can be provided with an outer thread 11, and the thread butt joint of the two can be realized.

[0056] As shown in Figure 7 Preferably, the positioning buckle 31 is arranged at the outer thread 11 away from the end face of the first assembly 10, and the positioning groove 33 is arranged at the position corresponding to the positioning buckle 31 of the inner thread 21 of the second assembly 20.

[0057] Specifically, the outer thread 11 extends a certain number of turns from the end face of the arrangement end along the axial direction, which is equivalent to arranging the positioning buckle 31 at the innermost position of the outer thread 11, so as to prevent the positioning buckle 31 from being arranged too close to the end face and being easily broken by misoperation or other accidents during the butt joint of the first assembly 10 and the second assembly 20.

[0058] Secondly, the positioning buckle 31 can also be directly arranged at the last circle of the external thread 11, so that when the threaded connection is screwed to the last circle, the positioning buckle 31 is just in engagement with the positioning groove 33 to form a positioning effect, which can not only make the screwing between the internal thread 21 and the external thread 11 tight, but also position the final screwing angle.

[0059] In addition, as shown in the drawings, Figure 6 The positioning groove 33 is only an inwardly recessed pit or a notch or a through hole, and does not break, so it can be arranged at the starting circle of the internal thread 21 of the second assembly 20. At the starting circle of the internal thread 21, the screwing connection is just corresponded to the last circle of the external thread 11.

[0060] As shown in the drawings, Figures 1 to 4 Preferably, one end of the positioning buckle 31 is fixed to the first assembly 10 or the second assembly 20, and the other end is formed as a free end, so as to form an elastic member with a certain deformation capacity, and a trapezoidal protrusion 32 is arranged at the free end, so that the trapezoidal protrusion 32 can be clamped into the positioning groove 33 to form a separable engagement connection.

[0061] Specifically, the positioning device 30 corresponds to the positioning of the rotation of the thread, so that it is fixed at a preset rotation angle, so that the sides of the first assembly 10 and the second assembly 20 can be kept coplanar, that is, the corresponding sides of the two triangular prisms are kept in the same plane, that is, the corresponding sides are kept aligned with each other. Or, after the threaded connection of the two triangular prisms, the parallelism error between the adjacent sides should be controlled within a very small range to ensure that the sides are aligned with each other.

[0062] Secondly, as shown in the drawings, Figure 4 The trapezoidal protrusion 32 of the positioning buckle 31 can be chamfered on both sides along the spiral direction of the thread, so that when it slides on the thread structure, it can better slide between the protrusions of the thread or between the side walls of the positioning groove 33. Similarly, as shown in the drawings, Figure 1 The side wall of the positioning groove 33 corresponding to the unlocking direction of the positioning buckle 31 can also be chamfered. When the first assembly 10 and the second assembly 20 are unlocked, the trapezoidal protrusion 32 of the positioning buckle 31 is separated from the chamfered side wall to realize the unlocking operation.

[0063] Please refer to Figures 1 to 8 In the embodiment of the utility model, a microphone comprises a main body 40, a net head 41 and a tail 42, the net head 41 and the tail 42 are connected to the two ends of the main body 40 respectively, wherein the main body 40, the net head 41 and the tail 42 are arranged as polygonal shapes respectively.

[0064] Specifically, in order to prevent the microphone from rolling on the plane, a part of the microphone that contacts the plane can be set to a polygonal shape, such as a triangular prism shape, so that its cross-section is an equilateral triangle. When the microphone is placed on a plane such as a table, any side of the polygonal prism can contact the plane and achieve stable placement, preventing rolling and reducing the risk of equipment damage. For example, only the mesh head 41 can be set to a polygonal shape, or only the main body 40 can be set to a polygonal shape, or only the tail fixture 42 can be set to a polygonal shape. As long as the part set to a polygonal shape contacts the plane first, the anti-rolling effect can be achieved.

[0065] Secondly, in order to unify the appearance and improve the aesthetics, it is preferred that the main body 40, the mesh head 41 and the tail fixture 42 are all set to the same polygonal shape, such as a triangular prism shape, so that after the three are connected, a unified appearance can be formed, achieving the anti-rolling effect and improving the aesthetics. The edges of the polygonal prism can all be rounded to provide a comfortable grip. In order to further improve the comfort of the grip, the side of the main body 40 can be set to have a certain curvature, rather than being a pure plane. As shown in Figure 3 The mesh head 41 is relatively large in size, so when the microphone is placed on a plane such as a table, the mesh head 41 part usually directly contacts the plane. Therefore, the side of the mesh head 41 part is preferably set to a pure plane, so that the side or both ends of the side can maintain a face-to-face contact state or an edge-to-face contact state when contacting the plane, thereby preventing rolling.

[0066] In addition, as shown in Figure 6 It is preferred that a silicone anti-slip pad 43 can be provided on the outer wall of the microphone, such as on the outer wall of the tail fixture 42. The silicone anti-slip pad 43 can further prevent the microphone from sliding, and in combination with the triangular prism structure, the dual anti-rolling and anti-falling effects can be achieved.

[0067] As shown in Figure 6 and Figure 7 It is preferred that the mesh head 41 and the tail fixture 42 are respectively threadedly connected to the two ends of the main body 40, thereby forming a detachable fixed connection. The two ends of the main body 40 are respectively provided with external threads 11, one end of the mesh head 41 and the tail fixture 42 is respectively provided with an internal thread 21, and a positioning device 30 is arranged between the external thread 11 and the internal thread 21, thereby locking the rotation angle of the threaded connection, so that the sides of the mesh head 41 and the tail fixture 42 respectively maintain a coplanar state with the corresponding sides of the main body 40.

[0068] Specifically, the positioning device 30 can lock the positional relationship of the mesh head 41 and the tail fixture 42 when they are respectively threadedly connected to the main body 40, so that the corresponding sides of the three maintain a coplanar state and do not form a misaligned relationship with each other, thereby improving the aesthetics and maintaining stable connection.

[0069] like Figures 5 to 7 As shown, preferably, the main body 40 is provided with a bracket 50, a cover plate 60, a sleeve 70 and an electronic component 80. The two ends of the bracket 50 are respectively provided with external threads 11, so as to be threadedly connected to the head 41 and the tail 42 respectively. The electronic component 80 is installed on the bracket 50, the cover plate 60 is fastened to the bracket 50, and the sleeve 70 is sleeved on the bracket 50.

[0070] Specifically, to facilitate assembly, simplify the assembly process, and reduce assembly time, the main body 40 can be configured as a modular quick-release structure. That is, a main support 50 is set inside the main body 40, allowing the mesh head 41 and tail 42 to be connected to both ends of the support 50 respectively. The corresponding electronic components 80 can be mounted on the support 50, and then the cover plate 60 is fastened to the support 50 using clips 61 to cover the electronic components 80. Alternatively, a sleeve 70 can be provided to cover the entire main body 40, protecting the internal components and creating a uniform shape.

[0071] Secondly, the electronic component 80 includes electronic components such as a microphone sensor 81, a circuit board 82, a display screen 83, a switch button 84, an adjustment button 85, and a power supply battery. The microphone sensor 81 is installed at one end of the bracket 50 connected to the mesh head 41. The limiting notch on the circuit board 82 cooperates with the limiting post 51 on the bracket 50 to limit its installation on the bracket 50. It is also fixed to the bracket 50 by welding through the battery connection terminal. The battery connection terminal can be fixed to both ends of the battery compartment 52 of the bracket 50 through the existing slot structure, so that the power supply battery can be replaced and installed in the battery compartment 52 and form an electrical connection with the circuit board 82, thereby providing power for the operation of the electronic components.

[0072] Again, the display screen 83, the switch button 84 and the adjustment button 85 can be directly welded on the circuit board 82 to realize the corresponding functions. The cover plate 60 can also be provided with pressing tablets corresponding to the switch button 84 and the adjustment button 85, so that the buttons can be pressed. Since the adjustment button 85 usually only needs to adjust the relevant parameters of the microphone at the first time of use, the corresponding opening can not be provided on the sleeve 70. When adjustment is needed, the sleeve 70 is removed for adjustment. The power button needs to be used frequently, and the corresponding opening can be provided on the sleeve 70. Similarly, the display screen 83 also needs to be provided with an opening corresponding to the position of the sleeve 70, so that it can be normally displayed. In order to protect the display screen 83, the cover plate 60 corresponding to the position of the display screen 83 can be made of transparent or translucent material. In order to simplify production, the entire cover plate 60 can also be made of transparent or translucent material. After such setting, the top surface of the display screen 83 and the switch button 84 is protected inside the outer wall of the sleeve 70, so that it will not cause wear to the display screen 83 and the switch button 84 during use, and the service life and aesthetic appearance are improved.

[0073] In addition, other electronic components in the prior art, such as control chips, conversion chips, power supply chips, etc. can also be provided on the circuit board 82 to realize the corresponding functions of the microphone. For example, a wireless antenna and other related accessories can also be provided to realize the function of wireless transmission. The energy supply battery installed in the main body 40 can be directly replaced and charged using an external charger. The charging plug 44 can also be provided on the tail part 42, and the energy supply battery can be directly charged using a charging line.

[0074] As shown in Figure 6 and Figure 7 Preferably, the outer wall of one side of the bracket 50 is provided with a guide groove 53 along the axial direction thereof, and the inner wall of the sleeve 70 is provided with a guide strip 71 corresponding to the position of the guide groove 53. The guide strip 71 and the guide groove 53 are matched with each other to form a limiting sliding connection.

[0075] Specifically, in order to optimize the assembly process of the sleeve 70 and avoid assembly errors caused by position deviation during assembly, the guide groove 53 and the guide strip 71 can be provided, so that the sleeve 70 can utilize the characteristics of the limiting sliding of the guide strip 71 along the guide groove 53 to assist the assembly of the sleeve 70. The guide groove 53 can also be provided with an opening 54 facing the assembly direction of the sleeve 70, so that the guide strip 71 can be easily slid into the guide groove 53 through the opening 54.

[0076] As shown in Figure 8As shown, preferably, when the mesh head 41 uses a metal material, such as a zinc alloy mesh head 41, since it has no elasticity and is not convenient to set the positioning buckle 31, a metal mesh seat 46 can be provided at the connecting end of the metal mesh cover 45, and a connecting piece 47 with elasticity, such as a connecting piece 47 made of plastic material or plastic material, is installed at the part of the metal mesh seat 46 connecting the support 50. By using its good plastic forming performance, the positioning buckle 31 can be provided on the connecting piece 47. In this way, even if the mesh head 41 uses a metal material, it also has the positioning function of preventing misplacement. In addition, dustproof cotton 48 can also be provided inside the mesh head 41 to achieve dustproof effect.

[0077] The specific assembly process is as follows:
