Description

Technical Field

[0001] The utility model relates to a microphone stand, in particular to a connector structure in the microphone stand. The connector is used to connect a vertical pole and a horizontal pole with a microphone installed at one end. The angle of the horizontal pole can be adjusted by adjusting the connector. Background Art

[0002] A microphone stand is a device designed for live events such as concerts and speeches to stably support the microphone. It consists of a base, a pole and a crossbar. The base provides stability, the pole can be adjusted in height, and the crossbar allows the microphone to be adjusted at multiple angles to optimize sound capture.

[0003] The crossbar and the vertical pole are connected by a connector, which consists of a splint, an adapter, a shaft hole and a locking device. The splint ensures that the crossbar is firmly fixed, the adapter and the shaft hole cooperate to achieve smooth rotation, and the locking device prevents loosening and ensures stability during use. The design of the connector needs to be optimized to improve load-bearing and stability to adapt to equipment of different weights and usage requirements.

[0004] For example, a microphone stand connector with publication number CN201054754Y includes a left clamping plate, a right clamping plate and an adapter, the left clamping plate and the right clamping plate are symmetrically arranged, the left clamping plate and the right clamping plate form an upper clamping cavity and an axial hole, the upper part of the adapter is provided with a rotating shaft, the rotating shaft and the axial hole cooperate with each other, the lower part of the adapter is connected to the vertical rod, the upper clamping cavity is sleeved on the horizontal rod, and the locking device is arranged between the upper clamping cavity and the axial hole. The screw and the shaft hole of the connector are not on the same axis, and the force points of the two are at different positions, which easily leads to the problem of poor locking due to the inability to further lock the rotating shaft after the screw is tightened.

[0005] When the microphone stand is in use, a shelf is installed at the front end of the microphone stand, and mobile terminals such as tablet computers and mobile phones are placed on the shelf. Due to the structural limitations of existing connectors, the front end of the existing microphone stand can only bear a load of 3-4 kg. When the weight exceeds this, the crossbar of the microphone stand will deflect. Utility Model Content

[0050] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It will be appreciated by those skilled in the art that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0051] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it will not be further defined or explained in the subsequent drawings.

[0052] like Figure 1 As shown, the microphone stand 100 includes a base 101 for supporting on the ground, a vertical pole 102 for supporting the connector 104 to a certain height in the longitudinal direction, a horizontal rod 103 for extending the connector body 10 in the horizontal range, and a connector 104 for mounting a mobile device (such as a mobile phone, a tablet, a microphone or a music stand, etc.). Preferably, the vertical pole 102 and the horizontal rod 103 are both retractable structures.

[0053] The connector 21 of the connector 104 is threadedly connected to the upper end of the vertical rod 102 for fastening, and the cross bar 103 is inserted into the tubular body 11 of the connector body 10. The cross bar 103 is inserted into the tubular body 11 of the connector body 10. When assembling, the cross bar 103 can move in a certain range of orientation (axial direction) inside the tubular body 11, ensuring accurate assembly positioning, and faster installation and position adjustment. The inner wall of the tubular body 11 is provided with friction textures or elastic stoppers to increase the friction with the cross bar 103 to prevent the cross bar from sliding or deflecting when subjected to force (specific details will be explained below).

[0054] like Figures 2 to 7 As shown, the connector 104 includes a connector body 10, a transfer body 20, a die-cast conical pressure plate 80 and a locking device 40. These components work together to provide a strong load-bearing force and locking force, ensuring the stability and durability of the connector, and enabling the microphone stand to maintain a stable position of the crossbar 103 when carrying heavy objects, preventing deflection due to excessive weight.

[0055] Among them, Figure 3 and Figure 4 As shown, the connector body 10 is the core part of the microphone holder connector 104, which is composed of an integrally die-cast tubular body 11, a first clamping plate 12 and a second clamping plate 13. This integrated structure not only improves the integrity and stability of the structure, but also ensures seamless fit between the various components.

[0056] like Figure 3 and Figure 4 As shown, the adapter body 20 includes an integrally die-cast connector 21 and a connector plate 22. The integrated manufacturing process not only ensures the structural strength and durability of the adapter body 20, but also makes it easy to precisely adjust the dimensions to achieve the purpose of controlling the precise fit of the vertical rod 102 and the horizontal rod 103. When matched, the connector plate 22 is located between the first clamping plate 12 and the second clamping plate 13. The connector plate 22 is connected to the horizontal rod 103, and the connector head 21 is connected to the vertical rod 102. The connection of the horizontal and vertical rods is achieved through the adapter body 20, and it is sufficient to ensure the stability and connection strength of the connection point through its coordinated cooperation with other components, thereby achieving the technical purpose of enabling the outer end of the horizontal rod to bear a larger weight.

[0057] like Figure 3 and Figure 4As shown, the first clamping plate 12 is provided with a through hole p1 for the conical pressure plate 80 to pass through. Preferably, the inner wall of the through hole p1 is a positive annular surface (not a conical annular surface, that is, the annular surface is not inclined). At this time, the outer peripheral surface of the corresponding conical pressure plate 80 includes a second conical surface s2 and a positive annular surface. The positive annular surface of the conical pressure plate and the positive annular surface of the through hole p1 correspond to each other in position, and the widths of the two positive annular surfaces are consistent. This will make the fit between the first clamping plate 12 and the conical pressure plate 80 more precise, and help to achieve a tight and consistent connection. In addition, the mutual nesting and fit between the positive annular surfaces make it easier to assemble and adjust the two components, and it is also easier to achieve the coordination of the guide structure f between the first clamping plate 12 and the conical pressure plate 80 (this part is explained below).

[0058] From another perspective, the technical purpose of allocating the locking fit between the tapered inclined surfaces solely to the connecting disk 22 without involving the first clamping plate 12 is to reduce the structural complexity of the first clamping plate 12 and concentrate the tapered locking fit on the connecting disk 22, which can make the adjustment process more direct and flexible.

[0059] like Figures 5 to 7 As shown, the locking device 30 includes a screw 31 and a nut 32; after the screw 31 passes through each component, it is threadedly fastened with the nut 32.

[0060] The first side b1 of the connecting disk 22 facing the first clamping plate 12 is provided with a conical concave hole b2, and the conical pressure plate 80 falls into the conical concave hole b2 after assembly. Specifically, the conical concave hole b2 has a first conical surface s1, and the conical pressure plate 80 has a second conical surface s2. After assembly, the two conical surfaces cooperate with each other and lock. It should be noted that the locking effect is that the cooperation of the first conical surface s1 and the second conical surface s2 forms a self-locking mechanism. When the conical pressure plate 80 is pressed into the conical concave hole b2, due to the angle of the conical surface, a wedging effect is generated between them, so that initial stability can be maintained without an external locking element. Moreover, the two conical surfaces can be smoothly matched and separated, instead of relying on fasteners that may cause damage, reducing the damage that may be suffered by the components during clutch. The locking mechanism between the conical surfaces significantly enhances the load-bearing capacity of the connector, provides a solid foundation and reliable stability for supporting heavier loads, and the connector can also maintain its structural integrity and functionality, thereby meeting higher-demand application scenarios.

[0061] The tapered surface fit reduces the wear problem that may be caused by traditional threads or fasteners, because they rely mainly on form fit rather than friction to maintain locking. The tapered surface fit can also simplify the assembly process, because the user only needs to push the tapered pressure plate 80 into the tapered recessed hole b2 to achieve quick locking.

[0062] Furthermore, an elastic friction sheet 60 is provided between the connection disk 22 and the second clamping plate 13 to enhance the fastening force between the two. The introduction of the elastic friction sheet 60, through the elastic characteristics of its material, can generate a continuous and stable friction force between the connection disk and the clamping plate, thereby enhancing the fastening effect between the two. The presence of the elastic friction sheet 60 can also effectively absorb and buffer the energy caused by external impact or vibration.

[0063] During the assembly process, Figure 6 and Figure 7 as well as Figure 5 As shown, the screw 31 penetrates through multiple key components in a specific order: first through the conical pressure plate 80, then the connecting plate 22, then the elastic friction plate 60, and finally reaches and passes through the limiting through hole p2 of the second clamping plate 13. This continuous penetration process ensures precise alignment and tight fit between the various components. Subsequently, the screw 31 is locked using the nut 32 to complete the assembly. In this process, the first conical surface s1 and the second conical surface s2 are squeezed against each other due to the pulling force of the screw 31, forming a firm locking mechanism.

[0064] This assembly method not only ensures the stability and load-bearing capacity of the structure, but also enhances the self-locking characteristics of the connector through the mutual compression of the conical surfaces s1 and s2. The design of the conical surface produces a wedge effect when the screw 31 is tightened, which helps prevent the screw from loosening and maintains stability even under heavy loads or vibrations. In addition, the addition of the elastic friction plate 60 further increases the friction coefficient between the connecting disk 22 and the second clamping plate 13, ensuring the reliability and durability of the entire connector under various use conditions.

[0065] In addition, preferably, the first conical surface s1 and the second conical surface s2 have a certain degree of roughness. This roughness refers to a specific setting of the surface microstructure, which can provide better surface compatibility and achieve a tighter fit even when there are slight unevennesses on the contact surface. In other words, this microstructure can optimize the interaction between surfaces and improve the stability of the connection.

[0066] More preferably, a guide structure f is provided between the through hole p1 of the first clamping plate 12 and the conical pressure plate 80, and the guide structure f can move the conical pressure plate 80 in the axial direction. The existence of such a guide structure f effectively avoids the possible deviation or tilt of the conical pressure plate 80 during installation or adjustment by providing a clear moving path and directionality, thereby ensuring the precise fit between the conical pressure plate and the through hole.

[0067] In addition, the guide structure f includes a groove f2 formed on the outer peripheral side wall of the conical pressure plate 80, and a protrusion f1 correspondingly provided on the through hole p1 of the first clamping plate 12, and the groove f2 cooperates with the protrusion f1 to limit the rotation of the conical pressure plate 80. The cooperation between the groove f2 and the protrusion f1 provides a clear positioning point for the conical pressure plate 80, ensuring the precise alignment of the pressure plate during installation and adjustment. When carrying heavy objects or used in a dynamic environment, the guide structure f ensures that the conical pressure plate 80 will not rotate accidentally, thereby improving the stability of the connection.

[0068] Preferably, the groove f2 of the conical pressure plate 80 is located on its positive annular surface.

[0069] It should be noted that the wedging effect formed by the two conical surfaces and the circumferential limit formed by the guide structure f work together to form a composite limit mechanism, which not only prevents axial sliding, but also effectively prevents circumferential rotation, thereby improving the connector's ability to withstand loads in different directions, especially when carrying heavier cross bars or front-end equipment, and can maintain the stability and firmness of the structure, thereby providing all-round stability.

[0070] A nut 32 is specially provided at the tail of the screw 31 to achieve a firm fixation of the conical pressure plate 80. Furthermore, a decorative cover 70 is provided on the outer side of the second clamping plate 13, and the decorative cover is composed of a fixing sleeve 71 and a rear cover 72. The fixing sleeve 71 is mounted on the second clamping plate 13, and the rear cover 72 is connected to the fixing sleeve 71 by threads, and an inner cavity 73 is formed between the two, which is specifically used to accommodate the nut 32. Such a structure not only protects the nut and prevents it from loosening, but also adds a beautiful appearance to the entire connector.

[0071] In order to further improve the reliability of the connector, an anti-drop pin 33 is preferably provided at the tail end of the locking screw 31. This small component plays a key role, ensuring that the screw will not accidentally loosen or fall off even under strong vibration or impact, thereby ensuring the stability and safety of the microphone stand during use.

[0072] Preferably, bushings c are provided at both ends of the tubular body 11, which not only enhance the structural strength of the tubular body, but also integrate elastic parts c1 on the bushings c, which provide necessary elastic support and buffering for the tubular body 11, and help absorb and alleviate the stress caused by external impact or vibration.

[0073] In addition, a knob d is provided on the outer wall of the tubular body 11 , and the knob d is composed of a hand-tightening portion d2 and a push rod d1 . The push rod d1 is designed to press and release the elastic member c1 , so that the user can easily adjust the knob to meet different tightening requirements.

[0074] Preferably, in order to ensure the stability of the knob d during use, an anti-dropping pin c2 is specially provided on the push rod d1, thereby effectively preventing the knob d from accidentally falling off from the side wall cavity on the tubular body 11 due to external force, further improving the reliability and durability of the connector.

[0075] Preferably, the head of the locking screw 31 is provided with a radial through hole for installing the operating rod g. This technical means allows the user to perform a more convenient and intuitive locking or loosening action through the operating rod g. A sphere g0 is provided at each end of the operating rod g. These spheres not only provide a larger contact area and a better grip, but also allow the user to operate from different angles through their spherical design, thereby increasing the flexibility and comfort of use.

[0076] Furthermore, the fixing sleeve 71 includes a main body r1, a limiting protrusion r2 disposed on one side of the main body r1, and a threaded body r3 disposed on the other side of the main body r1. A limiting through hole p2 is provided on the second clamping plate 13, and the cross-sections of the limiting protrusion r2 and the limiting through hole p2 are polygons of the same shape, so that the limiting through hole p2 guides the limiting protrusion r2 to be inserted and limits the rotation of the limiting protrusion r2, providing an accurate and reliable positioning mechanism.

[0077] The inner peripheral wall of the rear cover 72 is provided with internal threads to be fastened with the external threads of the threaded body r3. The rear cover 72 can not only be firmly fixed in a proper position, but also provides a simple disassembly and assembly method, making the maintenance and adjustment process more convenient.

[0078] Preferably, the second side surface b2 of the connection disk 22 facing the second clamping plate 13 is provided with friction lines v to further increase the friction force between the connection disk 22 and the friction plate 60. The friction lines v are a plurality of radial convex ribs and / or concave strips that are spaced and annularly distributed.

[0079] The above technical means significantly improve the friction coefficient between the connection disk 22 and the friction plate 60, ensuring the firmness of the connection. The friction pattern v is composed of a plurality of radial convex ribs and / or concave strips that are spaced and annularly distributed, and these patterns create more contact points between the two contact surfaces, thereby physically enhancing the friction force.

[0080] In the description of the present utility model, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or the directions or positional relationships in which the utility model product is usually placed when in use, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present utility model. "First" and "second" are only for the purpose of making the description easier to understand, without any other directional meaning, and cannot be used as a limitation on the present utility model.
