Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone accessories, in particular to a ball head, a connecting mechanism and a mobile phone bracket. Background Art

[0002] Mobile phones have become an indispensable electronic product in people's work and life. In addition to work and social purposes, they have gradually become entertainment products with the enrichment of various software and hardware, which has greatly enriched people's spiritual life. In order to allow people to easily enjoy the spiritual entertainment brought by the mobile phone display content while working, handling life affairs or sleeping, people have created mobile phone holders. However, as people become more and more dependent on mobile phones, people usually need their mobile phones to be powered at all times. People usually clamp their mobile phones on the mobile phone holder and plug in the mobile phone charger. This will make the power cord messy and unsightly. Therefore, it is becoming more and more important to allow the mobile phone holder itself to have the function of charging the mobile phone. In order to allow the mobile phone holder to have the charging function, it is necessary to set up a power cord on the mobile phone holder. The connection between the clamping end and the bracket part of the traditional mobile phone holder is a fixed connection, such as a flexible bracket fixedly connected to the clamping end. The other is a rotatable connection, such as a ball head connection. Among them, the clamping end and the bracket part are fixedly connected, and the display direction of the mobile phone depends on the bending degree and angle of the flexible bracket. The adjustment is not only laborious and inconvenient, but also requires frequent adjustment. The mobile phone is prone to shaking and has gradually been eliminated. The ball head connection method is more and more popular because the bracket part usually adopts a more rigid base or metal bracket, etc., which makes the connection more rigid and the mobile phone is not easy to shake. However, since the clamping end and the bracket are connected by a ball head, the ball head is usually fixedly connected to the bracket through a rigid connecting rod. This method is not only inconvenient to set up the power cord, but also because the rotation direction and range of the ball head are usually not restricted, even if the power cord is set up, it is easy to get tangled or twisted during use. Utility Model Content

[0003] Based on the above, the present application provides a ball head that can limit the rotation direction and rotation range, which is used as an accessory of a mobile phone holder. It can limit the rotation direction and amplitude of the mobile phone to prevent the power cord of the mobile phone holder from being entangled or twisted.

[0004] In addition, the present application also provides a connecting mechanism using the ball head and a mobile phone holder using the ball head or the connecting mechanism.

[0005] A ball head includes a ball head body, and a limiting column is arranged on the ball head body; the limiting column is used to limit the rotation range of the ball head body after being installed in the ball head seat. In this way, by arranging a limiting structure in the ball head seat, the rotation direction and rotation range of the ball head can be limited, thereby limiting the rotation direction and range of the rotating device manufactured by using the ball head, such as limiting the rotation direction and range of the clamping end in the mobile phone holder, etc., and the limiting structure is arranged on the inner side of the ball head seat, which does not affect the overall aesthetics.

[0006] In one embodiment, the ball head body is further provided with a first wire passing hole and a second wire passing hole; the first wire passing hole is connected to the second wire passing hole; and the connection between the first wire passing hole and the second wire passing hole is stepped.

[0007] In one embodiment, the first wire passing hole is a round hole and is provided with an internal thread.

[0008] In one embodiment, the first wire passing hole and the second wire passing hole are both circular holes, and the aperture of the first wire passing hole is larger than the aperture of the second wire passing hole.

[0009] The ball head provided above, by setting a limit column on the ball head body, can use the limit mechanism set in the ball head seat to achieve hidden limiting. Not only can the purpose of limiting the rotation direction and range of the ball head be achieved, but the hidden limiting method does not affect the overall appearance of the rotating device using the ball head.

The limiting post 110 is used to limit the rotation range of the ball head body 100 after being installed in the ball head seat. In this way, by setting a limiting structure in the ball head seat, the rotation direction and rotation range of the ball head can be limited, thereby limiting the rotation direction and range of the rotating device manufactured by using the ball head, such as limiting the rotation direction and range of the clamping end in the mobile phone holder, and the limiting structure is arranged on the inner side of the ball head seat, which does not affect the overall aesthetics.

[0033] In one embodiment, if Figure 1 or Figure 2 As shown, the ball head body 100 is further provided with a first wire passing hole 120 and a second wire passing hole 130. The first wire passing hole 120 is connected to the second wire passing hole 130. The connection between the first wire passing hole 120 and the second wire passing hole 130 is in a stepped shape.
