Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of auxiliary equipment, and in particular to a stable rotating support. Background Technology
[0002] With the widespread use of smartphones, phone stands have become a common accessory in daily life. Especially when watching videos, making video calls, or taking photos from multiple angles, users have higher requirements for the flexibility and stability of phone stands.
[0003] One type of phone holder uses a rotating axis perpendicular to the back of the phone, relying on damping or friction to hold the phone at different angles, allowing it to be placed either vertically or horizontally. While this type of phone holder allows for multi-angle adjustment, it suffers from insufficient stability. For example, when subjected to external forces (such as touch or vibration), the phone holder is prone to accidentally rotating and shifting, causing it to lose its support and the phone to fall over. Such a phone holder cannot securely hold the phone in place. Utility Model Content
[0004] This invention provides a stable rotating bracket to solve the technical problem of insufficient stability of mobile phone holders.
[0005] This utility model provides a stable rotating bracket, including a mounting component and a support component. The mounting component includes a rotating part and a fixed part. One side of the rotating part is rotatably connected to the support component, and the other side is rotatably connected to the fixed part. The rotating part is provided with a protrusion, and the fixed part is provided with at least one groove that mates with the protrusion. After the rotating part rotates, the protrusion and the groove engage or disengage.
[0006] Furthermore, the rotating part is provided with a first clearance groove, and the rotating part is provided with a spring piece in the first clearance groove, and the protrusion is provided on the side of the spring piece near the fixed part.
[0007] Furthermore, the rotating part is rotatably connected to the fixed part, and multiple grooves are evenly provided on the fixed part along the circumferential direction of the rotating part's axis of rotation.
[0008] Furthermore, there are 12 grooves, and the fixing part has one groove every 30°.
[0009] Furthermore, the rotating part is provided with a buckle, one end of which is elastically connected to the rotating part, and the other end is rotatably engaged with the support member.
[0010] Furthermore, the support member is provided with a first limiting block near the buckle end, and a limiting groove is provided on the rotating part. After the support member rotates, the first limiting block abuts against the side wall of the limiting groove.
[0011] Furthermore, the buckle is provided with a second limiting block, and the support member abuts against the second limiting block after rotation.
[0012] Furthermore, the rotation range of the support member is 0-90°.
[0013] Furthermore, the support member has a flange at the end away from the rotating part.
[0014] Furthermore, a connector is provided on the side of the fixed part away from the rotating part.
[0015] Furthermore, the connector is a film or a magnetic sheet.
[0016] The beneficial effects of this utility model are as follows: The stable rotating bracket of this utility model, by setting a rotating part, a fixed part, and a support member, fixes the fixed part to the back of the mobile phone. The support member, after being rotated open, supports the mobile phone. Since the rotating part can rotate on the fixed part, it drives the support member to rotate, thus enabling the stable rotating bracket to fix the mobile phone from different angles. Under the action of the protrusion and the groove, when the protrusion engages in the groove, it restricts the rotation of the rotating part on the fixed part, acting as a damping effect. This makes it less likely for the support member to accidentally rotate under external force, thereby firmly supporting and fixing the mobile phone, and improving stability.

[0020] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that the embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Moreover, the features in the embodiments of the present invention can be combined with each other without conflict.
[0021] like Figures 1-3As shown, this utility model provides a stable rotating bracket, including a mounting part 1 and a support part 2. The mounting part 1 includes a rotating part 11 and a fixing part 12. One side of the rotating part 11 is rotatably connected to the support part 2, and the other side is rotatably connected to the fixing part 12. The rotating part 11 is provided with a protrusion 111, and the fixing part 12 is provided with at least one groove 121 that cooperates with the protrusion 111. After the rotating part 11 rotates, the protrusion 111 and the groove 121 are engaged or disengaged.
[0022] In one specific embodiment, such as Figure 1 As shown, both the rotating part 11 and the fixing part 12 are circular thin sheets with equal areas, and both are made of iron. Iron sheets have high hardness and are not easily deformed. The fixing part 12 is used to fit against the back of the mobile phone, fixing the entire stable rotating bracket to the back of the mobile phone. One side of the rotating part 11 is rotatably connected to the side of the fixing part 12 away from the mobile phone. A rivet 3 is installed at the center of the rotating part 11 and the fixing part 12. The fixing part 12 and the rotating part 11 are rotatably connected through the rivet 3, and the rotating part 11 can rotate 360° around the rivet on the fixing part 12.
[0023] The support member 2 is used to support a tilted mobile phone on an object such as a table. One end of the support member 2 is rotatably connected to the middle of the side of the rotating part 11 away from the fixed part 12. The axis of rotation of the support member 2 on the rotating part 11 is perpendicular to the axis of rotation of the rotating part 11 on the fixed part 12. After rotating on the rotating part 11, the support member 2 can be opened to support the mobile phone, or it can be attached to the rotating part 11 for storage. When the rotating part 11 rotates, it causes the support member 2 to rotate with the rotating part 11, so that the support member 2 can fix the mobile phone from different angles, such as vertical or horizontal.
[0024] A first clearance groove 112 is provided at the edge of the rotating part 11, and the first clearance groove 112 penetrates both sides of the rotating part 11. A spring piece 113 is integrally formed in the first clearance groove 112 within the rotating part 11. The spring piece 113 protrudes from the inner wall of the first clearance groove 112, and one end of the spring piece 113 is elastically connected to the inner wall of the first clearance groove 112. The spring piece 113 can elastically deform in the direction of both sides of the rotating part 11 within the first clearance groove 112, and the first clearance groove 112 provides space for the elastic deformation of the spring piece 113. A protrusion 111 is provided at the end of the spring piece 113 away from the inner wall of the first clearance groove 112, and is provided on the side of the spring piece 113 close to the fixing part 12. In its natural state, the spring piece 113 is located in the first relief groove 112, and the two sides of the spring piece 113 are parallel to the two sides of the rotating part 11. At this time, the protrusion 111 protrudes from the side of the spring piece 113 that is close to the fixed part 12. When the spring piece 113 undergoes elastic deformation, the spring piece 113 can move out of the first relief groove 112 in a direction away from the fixed part 12, so that the protrusion 111 is located in the first relief groove 112.
[0025] like Figure 2As shown, the groove 121 is formed at the edge of the fixing part 12. Preferably, 12 grooves 121 are evenly provided on the fixing part 12 along the circumference of the rotation axis of the rotating part 11, that is, one groove 121 is provided on the fixing part 12 every 30°. After the rotating part 11 rotates, the protrusion 111 can be aligned with any groove 121. When the rotating part 11 rotates continuously, the protrusion 111 can be aligned with any groove 121 in sequence. During the rotation of the rotating part 11, when the protrusion 111 is not aligned with the groove 121, the protrusion 111 abuts against the side of the fixed part 12 connected to the rotating part 11, and the spring piece 113 deforms away from the fixed part 12, so that the protrusion 111 is released from the groove 121 and the rotating part 11 can rotate on the fixed part 12; when the rotating part 11 rotates until the protrusion 111 is aligned with the groove 121, since the protrusion 111 protrudes from the side of the spring piece 113 near the fixed part 12, the protrusion 111 can be engaged in the groove 121, thereby restricting the rotation of the rotating part 11 on the fixed part 12, and thus the mobile phone is firmly fixed.
[0026] This utility model provides a stable rotating bracket by comprising a rotating part 11, a fixed part 12, and a support member 2. The fixed part 12 is fixed to the back of the phone, and the support member 2 is rotated open to support the phone. Since the rotating part 11 can rotate on the fixed part 12, it drives the support member 2 to rotate, thus allowing the stable rotating bracket to fix the phone at different angles. The protrusion 111 and the groove 121, when engaged within the groove 121, restrict the rotation of the rotating part 11 on the fixed part 12, acting as a damping mechanism. This prevents the support member 2 from accidentally rotating under external force, thus firmly supporting and fixing the phone, improving stability. Furthermore, the protrusion 111 and the groove 121 enable precise angle positioning, allowing users to quickly find the fixed position when adjusting the angle without repeated adjustments, resulting in a better user experience. The structure is simple, easy to operate, and low in cost.
[0027] It should be noted that the stable rotating bracket of this utility model can be used not only for mobile phones, but also for other electronic devices, such as tablets, and even non-electronic devices. As long as an item requires an adjustable bracket angle, the stable rotating bracket of this utility model can be used.
[0028] In this embodiment, the fixing part 12 is evenly provided with 12 grooves 121. The rotating part 11 and the support member 2 can rotate 12 times, and the mobile phone can adjust its angle 12 times. In other embodiments, it is not limited to this. The number of grooves 121 can also be 9, 10, 15 or 18, etc. The number of grooves 121 can be adjusted according to actual needs. In principle, as long as multi-angle adjustment can be achieved, it is acceptable. Multiple grooves 121 reduce the positioning interval and increase the angle selection, allowing the mobile phone to freely switch between landscape and portrait modes. Even in special scenarios where a tilted screen is required, it can be easily and stably positioned, ensuring stable placement of the mobile phone. It is more flexible and practical, which is conducive to meeting the user's needs for fine angle adjustment.
[0029] In one specific embodiment, such as Figure 2 and Figure 3 As shown, the rotating part 11 has two second clearance grooves 114 in the middle, which are located on both sides of the rivet 3 and penetrate both sides of the rotating part 11. A buckle 115 is integrally formed within the second clearance groove 114 of the rotating part 11. The buckle 115 protrudes from the inner wall of the second clearance groove 114, and one end of the buckle 115 is elastically connected to the inner wall of the second clearance groove 114. The buckle 115 can elastically deform in the direction of both sides of the rotating part 11 within the second clearance groove 114, which provides space for the elastic deformation of the buckle 115. A straight groove 21 is formed along the length of the middle of the support member 2. The straight groove 21 penetrates the support member 2 and connects to one end of the rotating part 11, forming two legs 22 at that end of the rotating part 11. Each leg 22 is recessed near the end of the rotating part 11 and fixedly connected to a connecting rod 23. The length direction of the connecting rod 23 is perpendicular to the length direction of the straight groove 21. The two legs 22 correspond to two latches 115, which are engaged with the connecting rod 23, allowing the legs 22 to rotate within the latches 115. The legs 22 are designed with two features that help balance the forces on the support member 2, further improving stability.
[0030] The support member 2 and the rotating part 11 achieve rotation and fixation through the pressure of the latch 115 on the connecting rod 23 and the friction between the latch 115 and the connecting rod 23. Specifically, as shown... Figure 1 As shown, when the support member 2 is in the retracted state, the support leg 22 is attached to the rotating part 11, the connecting rod 23 and the support leg 22 are on the same plane, the buckle 115 is in the natural state, and there is a gap between the connecting rod 23 and the buckle 115; Figure 2 and Figure 3As shown, during the opening process of the support member 2, the support leg 22 rotates on the surface of the rotating part 11, and the distance between the connecting rod 23 and the surface of the rotating part 11 gradually increases. The connecting rod 23 gradually abuts against the buckle 115, pushing the buckle 115 up. The buckle 115 undergoes adaptive elastic deformation in the direction closer to the support leg 22, causing the buckle 115 to press the connecting rod 23 tightly. As described above, when the user rotates the support member 2 to open it, the support member 2 remains relatively fixed under the frictional force between the connecting rod 23 and the buckle 115, thereby realizing the rotation and fixation of the support member 2 and the rotating part 11.
[0031] In one specific embodiment, the opening angle of the support member 2 should be limited, because the larger the opening angle of the support member 2, the greater the tilt angle of the mobile phone. This makes the support member 2 prone to accidentally rotating at a larger angle under the pressure of the mobile phone, causing the mobile phone to fall over. Therefore, a first limiting block 24 is integrally formed on the support member 2 to appropriately limit the rotation of the support member 2, and a limiting groove 116 that cooperates with the first limiting block 24 is provided on the rotating part 11. Figure 2 and Figure 3 As shown, the first limiting block 24 protrudes from the end of the support leg 22 near the buckle 115, and also protrudes from the side of the support leg 22 near the edge of the rotating part 11. Correspondingly, the limiting groove 116 is formed at the edge of the rotating part 11 and connects to the middle of the second clearance groove 114. When the support member 2 rotates, the first limiting block 24 can abut against the side wall of one end of the limiting groove 116, preventing the support leg 22 from rotating further, thereby preventing the support member 2 from opening at an excessive angle.
[0032] Furthermore, the buckle 115 is integrally formed with a second limiting block 1151 for appropriately restricting the rotation of the support member 2. For example... Figure 2 and Figure 3 As shown, the second limiting block 1151 protrudes from both sides of the end of the buckle 115 away from the inner wall of the second clearance groove 114. When the support member 2 rotates, the support leg 22 can abut against the second limiting block 1151, preventing the support leg 22 from rotating further, thereby further preventing the support member 2 from opening too wide. Preferably, the maximum rotation angle of the support member 2 is 90°.
[0033] In one specific embodiment, in order to facilitate opening the support member 2, a flange 25 is fixedly connected to the end of the support member 2 away from the rotating part 11. When the support member 2 is attached to the rotating part 11, the flange 25 protrudes on the surface of the rotating part 11, providing a place for the user to apply force to open the support member 2. Moreover, the flange 25 can also serve as a handle for rotating the support member 2, which has the advantage of improving convenience.
[0034] In one specific embodiment, a circular thin-film connector 4 is fixedly connected to the side of the fixing part 12 away from the rotating part 11. The area of the connector 4 is approximately the same as that of the fixing part 12. The connector 4 is a highly viscous film or a magnetic film. One side is used to connect to the fixing part 12, and the other side is used to connect to the mobile phone. The stable rotating bracket can be fixed to the back of the mobile phone through the connector 4, which is convenient and secure.
