[0034] The utility model will be described clearly, completely below in combination with the embodiment and the attached drawing to the concept of the utility model, specific structure and the technical effect produced, to fully understand the purpose, characteristics and effect of the utility model. Obviously, the described embodiment is only a part of the embodiment of the utility model, not all embodiments, based on the embodiment of the utility model, the other embodiments obtained by the skilled in the art without the premise of creative labor, all belong to the scope of the utility model protection. In addition, all the coupling / connection relations involved in the patent, not single component direct interface, but can be according to the specific implementation situation, by adding or reducing the coupling auxiliary member, to constitute the better coupling structure. The various technical features in the utility model creation can be interactively combined under the premise of not mutually contradictory conflict.

[0035] Refer to Figure 1A pivot 300 support bracket, comprising a fixed seat 100 and a mounting platform 200, respectively provided with opposite first and second support arms 110 and 210; the first and second support arms 110 and 210 are connected by a pivot 300, so that they can rotate relative to each other. The pivot 300 comprises a locking device 310, the locking device 310 comprises a bolt 311 passing through the first and second support arms 110 and 210, a nut 312 for locking the bolt 311, an elastic element 313 sleeved on the bolt 311, and at least one friction plate 314; when the first and second support arms 110 and 210 rotate relative to each other, the friction plate 314 is pressed between the first and / or second support arms 110 and 210 or on both sides by the compression of the elastic element 313, and the friction plate 314 generates a friction force with the first and / or second support arms 110 and 210 to provide a locking force when the first and second support arms 110 and 210 rotate relative to each other, so that the first and second support arms 110 and 210 can be suspended relative to each other at any position. It can be understood that the friction plate 314 can be arranged between the elastic element 313 and the first support arm 110, wherein the locking force comes from the friction force generated between the elastic element 313 and the first support arm 110 by providing pressure; similarly, the friction plate 314 can be arranged between the first and second support arms 110 and 210, between the bolt 311 and the second support arm 210; or, the above positions are all provided with the friction plate 314.

[0036] The function of the friction plate 314 is not only to provide friction, but also to effectively reduce the vibration and wear of the support arm when rotating relative to each other, and to prolong the service life of the pivot 300 support bracket. At the same time, the compression effect of the elastic element 313 between the friction plate 314 and the support arm can ensure that the locking effect remains stable under different load conditions, and ensure that the first and second support arms 110 and 210 can be stably suspended during operation. The material of the friction plate 314 can be selected according to different use scenarios, for example, a composite material with high friction coefficient can be used to improve the locking effect, or a wear-resistant material can be used to reduce the wear of the friction plate 314.

[0037] The pivot 300 support bracket structure of the utility model is simple, convenient to operate, and suitable for various mechanical systems that need to hover, fix or adjust the angle. By using the combination of the bolt 311, the nut 312 and the elastic element 313, the user can flexibly adjust the fastening degree of the locking according to the needs, and then control the relative rotation or stable suspension of the support arm.

[0038] Refer to Figures 1-3In some embodiments, the first support arm 110 is provided with a first gasket 120 on both sides or one side; the second support arm 210 is provided with a second gasket 220 on both sides or one side; the friction plate 314 provides locking force for the relative rotation of the first support arm 110 and the second support arm 210 by generating friction force with the first gasket 120 and / or the second gasket 220. It can be understood that the gasket can effectively disperse the action range of the friction force, reduce the direct contact between the friction plate 314 and the support arm, and thus reduce the wear and heat accumulation between the friction plate 314 and the support arm, prolong the service life of the assembly. At the same time, the gasket can improve the uniformity of the friction force, improve the stability of the locking force, and ensure the reliability and accuracy of the shaft 300 support in long-term use.

[0039] Preferably, the first gasket 120 and the second gasket 220 are arranged at the position where the first support arm 110 and the second support arm 210 contact each other, and the first gasket 120 or the second gasket 220 is arranged between the first support arm 110 and the second support arm 210 and the friction plate 314.

[0040] In some embodiments, referring to Figure 3 The friction plate 314 can be an oil storage friction plate 314, and both sides of the friction plate 314 are provided with a plurality of oil storage grooves to increase the friction force and stability during locking; the friction plate 314 can be a single friction plate 314 or a plurality of friction plates 314, and the number of friction plates 314 can be adjusted as needed to adapt to the locking force requirements of different application scenarios.

[0041] Further, the friction plate 314 has a first oil storage structure 3141, the first gasket 120 has a second oil storage structure 121, and the second gasket 220 has a third oil storage structure 221. The first oil storage structure 3141 is a plurality of oil storage grooves densely arranged on both sides of the friction plate 314, the second oil storage structure 121 is a plurality of oil storage holes arranged circumferentially along the first gasket 120, and the third oil storage structure 221 is a plurality of oil storage holes arranged circumferentially along the second gasket 220. It can be understood that the arrangement of the oil storage structure can effectively improve the lubrication performance of the friction plate 314 and the gasket, reduce the heat generated by the friction force, reduce the wear, and maintain stable friction force output, thereby improving the service life and performance of the shaft 300 support.

[0042] Specifically, the first oil storage structure 3141 (oil storage groove) can form a uniform oil film on both sides of the friction plate 314, and provide continuous lubrication effect through the oil storage capacity of the oil storage groove. This structure can continuously supplement lubricating oil when the friction plate 314 and the support arm rotate relative to each other, and prevent excessive heat and wear caused by friction.

[0043] Referring to Figure 3The second oil storage structure 121 and the third oil storage structure 221 are respectively arranged on the first gasket 120 and the second gasket 220, and a plurality of oil storage holes are arranged circumferentially on the gaskets to enable the transmission and distribution of oil between the gaskets and the friction plate 314, thereby further enhancing the lubrication effect between the friction surfaces. In this way, the friction plate 314 and the gaskets can maintain a more uniform lubrication state during operation, avoiding local high temperature and excessive friction, and improving the stability of the friction coefficient.

[0044] In addition, these oil storage structures can be optimized according to the use conditions. For example, in high-load or high-speed operation applications, the storage and release capacity of lubricating oil can be improved by increasing the number of oil storage grooves and oil storage holes or changing the depth and shape of the oil storage grooves to adapt to different working environments. In addition, the design of the oil storage grooves and oil storage holes can ensure the uniform distribution of lubricating oil between the friction plate 314 and the gaskets, thereby maximizing the friction effect between the friction plate 314 and the support arm and prolonging the service life thereof.

[0045] In some embodiments, with reference to Figure 3 , the first support arm 110 is provided with a first recess 111, and the first gasket 120 extends a first protruding column 122, which can be accommodated in the first recess 111 to prevent the first gasket 120 from rotating relative to the first support arm 110; the second support arm 210 is provided with a second recess 211, and the first gasket 120 extends a second protruding column 222; the second protruding column 222 can be accommodated in the second recess 211 to prevent the second gasket 220 from rotating relative to the second support arm 210. It can be understood that the first recess 111 and the second recess 211 can be optimized according to the shape of the gasket and the structure of the friction plate 314, so that the cooperation between the protruding column and the recess is more precise. Thus, the first gasket 120 and the second gasket 220 can be precisely positioned during installation, preventing them from shifting or rotating during use, thereby ensuring the reliability and stability of the locking device 310 throughout the working cycle. Not only does this improve the assembly accuracy of the components, but it also effectively reduces wear caused by rotation, prolonging the service life of the support of the rotating shaft 300. In addition, the size and shape of the first protruding column 122 and the second protruding column 222 can be adjusted as needed to accommodate different types of support arms and gasket configurations. For example, the height, diameter, and shape of the protruding column can be optimized according to the requirements of the friction plate 314 to better bear the working load and maintain a stable friction effect. The depth and shape of the recess can also be adjusted to ensure the secure positioning of the protruding column and prevent it from loosening or falling off during operation.

[0046] In some embodiments, the elastic member 313 is a spring. With reference to Figure 1 , 3The spring is preferably a disc spring, and the quantity can be selected according to specific needs.

[0047] In some embodiments, the bolt 311 is provided with a first stopper, the first support arm 110 or the second support arm 210 is provided with a second stopper, and the friction plate 314 is provided with a third stopper. The first stopper cooperates with the second and third stops to prevent relative rotation. It will be appreciated that the mechanical cooperation of the first, second, and third stops forms a stop mechanism that securely secures the friction plate 314 to the bolt 311 after installation, preventing rotation or displacement due to external forces. This ensures that the relative position between the friction plate 314 and the bolt 311 remains constant, and similarly, the relative position between the first support arm 110 or the second support arm 210 and the bolt 311 remains fixed. That is, while the first support arm 110 and the bolt 311 remain fixed relative to each other, the second support arm 210 and the bolt 311 are rotatably connected. This ensures the stability of the friction coefficient during relative rotation between the fixing base 100 and the mounting platform 200, improving the operational reliability of the device.

[0048] Specifically, the screw rod of bolt 311 has a planar structure parallel to the screw rod's axial direction. This means that the first stopper is a non-cylindrical structure of the screw rod. The third stopper on friction plate 314 corresponds to the through-hole provided in this structure, preventing the friction plate 314 from rotating relative to the screw rod after being mounted on the screw rod. Similarly, a second stopper is provided on first support arm 110 or second support arm 210, and the second stopper and the third stopper have the same structure.

[0049] In some embodiments, reference Figure 1 、 3 , the rotating shaft 300 also includes an outer shell 320, which is sleeved on the outside of the locking device 310 and fixed to the bolt 311 by a fastener. It can be understood that through the cooperation of the fastener and the bolt 311, the outer shell 320 can be firmly fixed to the outside of the device, providing additional support and impact resistance for the locking device 310, while making the entire rotating shaft 300 system more compact and stable. The effective protection of the outer shell 320 not only ensures the normal operation of the internal components, but also improves the safety of the device and prevents accidental damage or operational errors. Specifically, the fastener is a threaded part, and a threaded hole is provided on the screw rod of the bolt 311. The threaded part can fix the outer shell 320 by cooperating with the threaded hole.

[0050] In some embodiments, reference Figure 5The first through hole 130 is provided on the fixing base 100, and the second through hole 230 is provided on the mounting platform 200. It can be understood that the fixing base 100 can be placed on a plane or mounted on a wall. By providing the first through hole 130, the fixing base 100 can be stably connected with other support structures or mounting bases, ensuring the fixation and reliability of the device during installation. The design of the first through hole 130 enables the fixing base 100 to conveniently cooperate with fasteners, achieving rapid installation and avoiding complex installation steps and time waste. The second through hole 230 can be connected with electronic equipment, enabling the fixing base 100 and the electronic equipment to be firmly connected. The design of the second through hole 230 provides flexibility for installing electronic equipment, and users can select appropriate electronic equipment for installation according to actual needs, such as sensors, displays, or other control units, etc. In addition, the second through hole 230 can also serve as a channel for cables or data lines, facilitating the connection of electronic equipment and other external systems and realizing the transmission of signals or power.

[0051] Further, referring to Figure 1 The fixing base 100 has a fixing surface, and the mounting platform 200 has a mounting surface, and the fixing surface and the mounting surface are both provided with a buffer 160. The buffer 160 is mainly used to reduce vibration and impact during use of the device, preventing external impact forces from being transmitted to sensitive components inside the equipment. By providing the buffer 160 on the fixing surface and the mounting surface, the shock resistance of the device can be effectively improved, avoiding damage to the equipment caused by external vibration or collision.

[0052] Specifically, the buffer 160 is usually made of elastic materials such as rubber, silicone, or polyurethane, etc. These materials can absorb and disperse external impact forces, reducing the pressure on the fixing base 100 and the mounting platform 200 caused by external forces, thereby reducing the mechanical stress on the equipment. The shape and thickness of the buffer 160 can be adjusted according to the requirements of the use environment to achieve the best shock absorption effect.

[0053] In some embodiments, referring to Figure 4The fixing base 100 includes an outer seat 140 and an inner seat 150 in the same plane, and the first support arm 110 is located between the outer seat 140 and the inner seat 150 and is perpendicular to the plane where the outer seat 140 and the inner seat 150 are located. It can be understood that the fixing base 100 can effectively provide stronger support force and stability by being provided as the outer seat 140 and the inner seat 150. The outer seat 140 and the inner seat 150 form a structural frame to provide a stable mounting position for the first support arm 110, thereby avoiding unnecessary displacement or deformation of the support arm due to external force. Specifically, the inner seat 150 and the outer seat 140 are an integrally formed structure. Such a structure is suitable for being placed on a plane and does not need to be fixed by fasteners. At this time, the sound box and other equipment can be placed on the mounting platform 200.

[0054] The above is a specific description of the preferred embodiment of the present application, but the present application is not limited to the above-described embodiments. Those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the present application. These equivalent modifications or replacements are all included in the scope defined by the claims of the present application.
