[0027] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. Now, in conjunction with the accompanying drawings, a preferred embodiment of the present utility model is described in detail.

[0028] The present utility model embodiment provides a rotating device 1000, such as Figure 1-3 As shown, it includes: an upper body 100, a turntable 200, a lower body 300, a top cover 1011 and a fixing member 1012, the upper body 100 is provided with a cavity 101 and a receiving groove 102 arranged in layers, the bottom of the cavity 101 is provided with an opening 103, the opening 103 connects the cavity 101 and the receiving groove 102; the turntable 200 is arranged in the receiving groove 102, and a connecting rod 201 is arranged on the side of the turntable 200 facing the cavity 101, the connecting rod 201 extends into the cavity 101 through the opening 103 and extends from the upper body 100; the upper body 100 is rotatably connected with the lower body 300; the top cover 1011 is covered on the cavity 101, and a first through hole 10111 for the connecting rod 201 to pass through is provided on the top cover 1011, and the fixing member 1012 passes through the top cover 1011 and is connected to the upper body 100.

[0029] The upper body 100 and the lower body 300 are rotatably connected, so that the rotating device 1000 can rotate relative to each other, which improves the convenience of use for users. A cavity 101 and a receiving groove 102 are formed on the upper body 100, and a turntable 200 is arranged in the receiving groove 102. A connecting rod 201 is arranged on the turntable 200, and the connecting rod 201 passes through the opening 103 and the cavity 101 in sequence and extends to the outside of the upper body 100, so that the connecting rod 201 can be connected to an external mobile phone holder or other external structure. In actual use, the connection or separation with other external structures is achieved by twisting the turntable 200, so that the rotating device 1000 has good flexibility. A top cover 1011 is provided on the cavity 101, and the top cover 1011 is connected to the upper body 100 through a fixing member 1012, so that on the one hand, the fixing member 1012 can be hidden in the cavity 101 under the top cover 1011, ensuring the consistency of the appearance of the rotating device 1000. On the other hand, the fixing part 1012 is arranged in the cavity 101, and the fixing part 1012 is hidden inside the upper body 100, so it is possible to avoid the fixing part 1012 being arranged outside the upper body 100, which affects the smoothness of the outer surface of the upper body 100. Therefore, the setting form of the above-mentioned fixing part 1012 can improve the smoothness of the outer surface of the upper body 100 to a certain extent, so that it will not be affected by the setting of the fixing part 1012, thereby improving the user's touch feeling when using the rotating device 1000.

[0030] Specifically, the upper body 100 is connected to the lower body 300 by a rotational connection. This design enables the entire rotating device 1000 to realize the function of rotation or rotation. In the application of the neck hanging bracket, it is convenient for the user to adjust the angle and direction of the bracket to achieve better shooting effects.

[0031] Specifically, one end of the connecting rod 201 is connected to the rotating disk 200 disposed in the receiving groove 102, and the other end passes through the opening 103 and the cavity 101 in sequence and extends out of the first half body to achieve connection with other external structures, thereby improving the flexibility of the rotating device 1000.

[0032] It should be noted that in this embodiment, the connecting rod 201 is a threaded rod, which is connected to the external structure by threaded connection. In addition to the threaded rod, the connecting rod 201 can also be a rod body with a limit groove, which is connected by a locking connection with a limit buckle or other structure of the external structure.

[0033] Specifically, the detachable connection between the upper body 100 and the top cover 1011 is easy to disassemble and repair. The connection between the top cover 1011 and the upper body 100 can be released by simply removing the fixing member 1012, which makes the repair and replacement of the upper body 100 or the top cover 1011 more convenient.

[0034] Further, refer to Figure 2 A buffer layer 400 is also provided on the rotating device 1000 , and the buffer layer 400 is provided on the top cover 1011 .

[0035] The buffer layer 400 is disposed on the top cover 1011. First, the fixing member 1012 can be completely hidden under the buffer layer 400. The fixing member 1012 can be completely sealed by the buffer layer 400, thereby preventing the fixing member 1012 from being disturbed and affected by the external environment, thereby improving the service life of the fixing member 1012 and the connection stability between the top cover 1011 and the upper half 100. At the same time, the buffer layer 400 can also protect the top cover 1011, avoid friction between the top cover 1011 and other components or the external environment, ensure the structural stability of the top cover 1011, and extend the service life of the rotating device 1000.

[0036] Specifically, the buffer layer 400 can play a certain role in corrosion prevention, protecting the surface of the top cover 1011 from erosion by the external environment. It also has a certain buffering effect, which can alleviate the impact or fall of the top cover 1011 or the entire rotating device 1000, and extend the service life of the rotating device 1000. On the other hand, the design of the buffer layer 400 may also be aesthetically pleasing, and the fixing member 1012 and the gap between the top cover 1011 and the upper body 100 can be hidden, thereby improving the appearance of the rotating device 1000 and enhancing the overall visual experience.

[0037] It should be noted that the anti-slip stripes 600 provided on the buffer layer 400 can improve the friction between the external structure and the rotating device 1000, avoid loosening during use, and ensure the safety and stability of the connection between the rotating device 1000 and the external structure.

[0038] Further, refer to Figure 4 and Figure 5 , windows 1021 are opened on opposite sides of the accommodating groove 102 , the turntable 200 includes a connecting portion 202 and a toggle portion 203 , the connecting rod 201 is arranged at the connecting portion 202 , and the toggle portion 203 is exposed through the windows 1021 .

[0039] The window 1021 design allows the user to toggle the toggle portion 203 of the turntable 200 through the window, which is convenient for the user to operate and monitor the turntable 200, making the operation of the turntable 200 more convenient and quick. The connecting rod 201 is arranged at the connecting portion 202, which can ensure the stability and reliability of the connection between the connecting rod 201 and the turntable 200, and avoid loosening or falling off during use.

[0040] It should be noted that the anti-slip stripes 600 are provided on the toggle portion 203 to increase the friction between the finger or palm and the toggle portion 203, improve the stability during operation, and avoid misoperation or accidents caused by hand sliding.

[0041] refer to Figure 1 and Figure 6 A first connecting piece 104 is disposed on a side of the upper body 100 away from the accommodating groove 102 , and a second connecting piece 301 is disposed on a side of the lower body 300 facing the upper body 100 . The first connecting piece 104 is rotatably connected to the second connecting piece 301 .

[0042] The connection between the first connecting piece 104 and the second connecting piece 301 realizes the rotation connection between the upper body 100 and the lower body 300, and this connection mode can make the upper body 100 and the lower body 300 relatively rotatable. In this embodiment, the upper body 100 and the lower body 300 are connected by damping rotation, so when the user uses the rotating device 1000, shooting at a specific angle and direction can be achieved.

[0043] There are many ways to set the rotational connection between the first connecting piece 104 and the second connecting piece 301, for example: an integrated rotation shaft is set on one of the first connecting piece 104 or the second connecting piece 301, and a through hole for rotating relative to the rotation shaft is set on the other. For another example: through holes are set on both the first connecting piece 104 and the second connecting piece 301, and the rotational connection is achieved by connecting the external rotation shaft with the first connecting piece 104 and the second connecting piece 301. For another example, a bearing is set between the first connecting piece 104 and the second connecting piece 301, and the two are respectively set on both sides of the bearing to achieve the rotational connection between the first connecting piece 104 and the second connecting piece 301.

[0044] refer to Figure 1 and Figure 6 Two first connecting pieces 104 are arranged at intervals, three second connecting pieces 301 are arranged at intervals, and two first connecting pieces 104 are respectively arranged between two adjacent second connecting pieces 301 .

[0045] By increasing the number of first connecting pieces 104 and second connecting pieces 301, the stability of the connection between the upper body 100 and the lower body 300 can be increased. The first connecting piece 104 is connected to two adjacent second connecting pieces 301, which helps to disperse the pressure and maintain the firmness of the connection between the first connecting piece 104 and the second connecting piece 301.

[0046] Specifically, by connecting two adjacent second connecting pieces 301 with two first connecting pieces 104 , a balanced distribution of load can be achieved, the situation of excessive local force can be reduced, and the durability of the rotating device 1000 can be improved.

[0047] On the other hand, the design of multiple first connecting pieces 104 and multiple second connecting pieces 301 can improve the load-bearing capacity when the upper half 100 and the lower half 300 are connected, so that the rotating device 1000 can withstand greater force or torque, thereby improving the structural strength and stability of the rotating device 1000. The increased contact area between the first connecting piece 104 and the second connecting piece 301 can improve the limiting and positioning of the first connecting piece 104 and / or the second connecting piece 301, and ensure the stability of the rotation process.

[0048] It should be noted that, in addition to the above-mentioned connection methods, there are various other ways to set the first connection sheet 104 and the second connection sheet 301. For example, one first connection sheet 104 is set to connect with one second connection sheet 301. For another example, one of the first connection sheet 104 and the second connection sheet 301 is set to connect with two. For another example, multiple first connection sheets 104 and multiple second connection sheets 301 are set.

[0049] refer to Figure 1 and Figure 6 In an optional embodiment of the utility model, in order to ensure stability and limitation between the upper body 100 and the lower body 300 at a specific angle and direction, a locking mechanism 500 can be set on the first connecting piece 104 and the second connecting piece 301, so a first connecting hole 1041 is set on the first connecting piece 104, and a second connecting hole 3011 corresponding to the first connecting hole 1041 is set on the second connecting piece 301. The rotating device 1000 includes a locking mechanism 500, and the locking mechanism 500 passes through the first connecting hole 1041 and the second connecting hole 3011 to lock the first connecting piece 104 and the second connecting piece 301.

[0050] By locking or loosening the first connecting piece 104 and the second connecting piece 301 by the locking mechanism 500, the mobility between the first connecting piece 104 and the second connecting piece 301 can be changed, and the first connecting piece 104 and the second connecting piece 301 can be locked when necessary, so that the upper body 100 can be kept at a special angle and direction with the lower body 300, thereby facilitating the user to use the rotating device 1000. In the application of the neck bracket, it is convenient for the user to keep electronic products such as mobile phones or cameras at the desired angle for shooting or use. At the same time, the locking mechanism 500 can keep the connection between the upper body 100 and the lower body 300 in a stable and firm state, avoiding the situation where the electronic products are damaged due to accidental loosening.

[0051] Specifically, the presence of the locking mechanism 500 can improve the safety of the device. When the first connecting piece 104 and the second connecting piece 301 need to be locked, the connection between the two can be kept in a locked state to avoid loosening or falling off during use, thereby reducing the possibility of accidents.

[0052] Specifically, the design of the locking mechanism 500 can facilitate the user to adjust the angle and direction between the upper half 100 and the lower half 300 to a desired state and lock it, so that the user can use the rotating device 1000 in the desired state. At the same time, the locking mechanism 500 makes the operation of the rotating device 1000 more convenient, and the user can easily lock or unlock the first connecting piece 104 and the second connecting piece 301, which is convenient for operation.

[0053] Further, refer to Figure 6 A fixing platform 1042 is provided on the outward side of the first connecting hole 1041 and / or the second connecting hole 3011, and the locking mechanism 500 includes a knob 501, a connecting member 502 and a nut 503 connected in sequence, the connecting member 502 abuts against one of the fixing platforms 1042, and a screw rod 5021 is provided on the end of the connecting member 502 away from the knob 501, the screw rod 5021 passes through the first connecting hole 1041 and the second connecting hole 3011 and is connected to the nut 503, and the nut 503 is arranged in the other fixing platform 1042.

[0054] In actual use, a section of the connecting member 502 in the locking mechanism 500 is provided with a screw rod 5021, which passes through the first connecting hole 1041 and the second connecting hole 3011, and is connected to a nut 503 provided in the other side fixing platform 1042. Because the nut 503 is fixed in the fixing platform 1042, and the connecting member 502 abuts against the other fixing platform 1042, when the knob 501 is twisted, the screw rod 5021 can rotate relative to the nut 503, so that the screw rod 5021 can move relative to the first connecting hole 1041 and the second connecting hole 3011, so that the pressure between the two fixing platforms 1042 changes, thereby achieving locking or unlocking of the connection between the first connecting piece 104 and the second connecting piece 301. The fixing platform 1042 can increase the contact area between the connecting member 502 and the first connecting piece 104 and / or the second connecting piece 301, and can absorb the pressure generated between the connecting member 502 and the nut 503, thereby avoiding damage to the first connecting piece 104 and the second connecting piece 301 due to excessive pressure. On the other hand, the connection between the connecting member 502 and the fixing platform 1042 can increase the stability of the abutment between the two and reduce the looseness and shaking of the connection.

[0055] Specifically, through the design of the knob 501, the rotation of the screw 5021 relative to the nut 503 can be easily adjusted, thereby adjusting the tightness of the connection between the first connecting plate 104 and the second connecting plate 301, so that the user can flexibly adjust the tightness of the connection as needed, thereby improving the flexibility and operability of the rotating device 1000.

[0056] refer to Figure 2 and Figure 3 The fixing member 1012 is a screw, a connecting column 1013 is provided at the bottom of the cavity 101, and a second through hole 10112 is provided on the top cover 1011. The screw passes through the second through hole 10112 and is connected to the connecting column 1013.

[0057] The screw as the fixing member 1012 has a strong fixing ability and can ensure the firmness of the connection between it and the connecting column 1013. The screw passes through the second through hole 10112 and is connected to the connecting column 1013, which improves the firmness and stability of the connection between the top cover 1011 and the upper body 100, prevents the top cover 1011 from loosening or falling off during use, and reduces failures or damages caused by loose connections.

[0058] Specifically, a screw is used as the fixing member 1012, which passes through the second through hole 10112 to connect with the connecting column 1013. This connection method is relatively stable and strong, which reduces the risk of the fixing member 1012 becoming loose during use, ensures that the connection between the fixing member 1012 and the connecting column 1013 is in a firm state, and improves the safety and stability of the rotating device 1000. On the other hand, the above connection method simplifies the connection structure between the top cover 1011 and the upper body 100. At the same time, the use of screws as the fixing member 1012 makes the assembly and disassembly operations between the fixing member 1012 and the connecting column 1013 more convenient and easy to operate. The screw fixing method can effectively

[0059] Further, refer to Figure 3 , Figure 4 and Figure 7 Positioning platforms 1014 are respectively provided on two opposite sides of the cavity 101 , and a positioning groove 10113 corresponding to the positioning platforms 1014 is provided on one side of the top cover 1011 facing the cavity 101 .

[0060] Positioning platforms 1014 are respectively provided on the opposite sides of the cavity 101, and positioning grooves 10113 are provided on the top cover 1011 to cooperate with the positioning platforms 1014, so that the top cover 1011 can be conveniently and quickly positioned and installed on the cavity 101, and the problem of not being able to correspond the connecting column 1013 in the cavity 101 with the second through hole 10112 on the top cover 1011 during the installation process can be avoided, thereby playing a role of rapid positioning and rapid installation, improving the installation efficiency of the top cover 1011, and saving time and effort.

[0061] During actual use, due to the cooperation between the positioning platform 1014 and the positioning groove 10113, when the user places the top cover 1011, the user can position the connecting column 1013 and the second through hole 10112 at the same time through the positioning between the positioning platform 1014 and the positioning groove 10113, thereby avoiding the trouble that the user cannot observe the specific position of the connecting column 1013 in the cavity 101 after placing the top cover 1011, and needs to make multiple adjustments to make the connecting column 1013 correspond to the second through hole 10112, thereby simplifying the installation process and improving the convenience of the rotating device 1000.
