[0018] The utility model will be described in detail below in combination with the drawings and specific embodiments.

[0019] Please refer to Figs. 1 to 4The utility model provides a device for firm CD mouth support can improve torsion, include: support base 1 and the hinge piece 2 of hinging on support base 1, the hinge piece 2 adopts U type structure, the root of both sides branch of U type structure is hinged on support base 1 respectively, the middle region of U type structure is provided with connecting hole 21, support base 1 is provided with first threaded hole corresponding connecting hole 21, the lock screw 3 of screwing in first threaded hole, the end of lock screw 3 is equipped with adjusting block 31, when adjusting lock screw 3 makes adjusting block 31 move towards the direction of support base 1, adjusting block 31 will push the middle region of U type structure and move towards the direction of support base 1, so that hinge piece 2 rotates around the hinging position. The lock screw 3 adopts double -end screw, the both ends of lock screw 3 are provided with first threaded section 32 and second threaded section 34 respectively, first threaded section 32 is engaged with first threaded hole, adjusting block 31 is provided with second threaded hole, second threaded section 34 is engaged with second threaded hole.

[0020] When installing and fixing CD mouth support on CD mouth, first through the rotation adjusting block 31, so that adjusting block 31 is locked on second threaded section 34, fix hinge piece 2, then rotate lock screw 3, drive first threaded section 32 and rotate along first threaded hole, so as to pull hinge piece 2 and rotate around the hinging position, so that the branch of hinge piece 2 and support base 1 cross and develop, to this form tension, firmly embed CD mouth support on the upper and lower inner wall of CD mouth, so as to play the supporting role to car navigation equipment such as mobile phone, tablet computer or central control screen, and because both ends are stressed, therefore not easy to fall off from CD mouth support in the process of driving, avoid the safety hazard that the driver is distracted because of navigation equipment falling, improve the safety in the process of driving.

[0021] In some embodiments, the outer diameter of the first threaded section 32 is greater than the outer diameter of the second threaded section 34, and the outer diameter of the first threaded section 32 is greater than the hole diameter of the connecting hole 21 of the hinge piece 2. Because the outer diameter of the first threaded section 32 is relatively large, the hinge piece 2 can be clamped and fixed by the end surface of the first threaded section 32 and the end surface of the adjusting block 31. This facilitates the adjustment of the position of the hinge piece 2 by rotating the lock screw 3, so that both sides of the hinge piece 2 can be supported. This effectively improves the support force of the hinge piece 2 after expansion, and avoids the loosening of the hinge piece 2 affecting the overall support of the CD mouth support.

[0022] In some embodiments, the bracket base 1 adopts an E-shaped structure, and the two side branches of the hinge piece 2 are respectively located in the space between the branches of the E-shaped structure. By setting the bracket base 1 as an E-shaped structure, when the branches of the hinge piece 2 are inserted into the CD port, the front end of the bracket base 1 is also embedded into the CD port, and when the hinge piece 2 is opened, the branches of the bracket base 1 and the hinge piece 2 respectively support and fix the CD port from the top and bottom directions, thereby forming a tension and improving the stability of the connection between the CD port bracket and the CD port.

[0023] In some embodiments, the top and bottom surfaces of the branches of the hinge piece 2 and the branches of the bracket base 1 are respectively provided with anti-skid pads 4. When the hinge piece 2 is crossed and opened in the CD port, the anti-skid pads 4 on the hinge piece 2 and the bracket base 1 will contact the inner wall of the CD port, and the friction force is increased through the anti-skid pads 4, thereby avoiding the sliding of the hinge piece 2 in the CD port, and further avoiding the shaking or falling off of the hinge piece 2 from the CD port, and improving the stability of the installation and fixation of the CD port bracket.

[0024] In some embodiments, one end of the first threaded section 32 of the double-headed screw is provided with a handle 34, and the handle 34 adopts a straight handle or a star-shaped handle. By setting the handle 34 at the end of the double-headed screw, the user can rotate the handle 34 to rotate the double-headed screw, thereby driving the hinge piece 2 to expand and contract, and meeting the installation and removal requirements of the CD port bracket.

[0025] In some embodiments, the connecting hole 21 adopts a strip hole, and the strip hole is distributed in a direction parallel to the two side branches of the hinge piece 2. When the hinge piece 2 rotates around the hinge position, the connecting hole 21 and the locking screw 3 will be offset. By adopting a strip hole as the connecting hole 21, there is a corresponding empty interval between the connecting hole 21 and the locking screw 3, which meets the rotation requirements of the hinge piece 2 and avoids affecting the rotation state due to interference.

[0026] In some embodiments, the side of the bracket base 1 away from the two side branches of the hinge piece 2 is provided with a ball joint 11, a bracket seat 51 is movably sleeved on the ball joint 11, an external locking thread is arranged on the outer side of the bracket seat 51, a locking nut 52 is screwed on the external locking thread, and the locking nut 52 is sleeved on the ball joint 11 and locked on the external locking thread. The bracket seat 51 can be provided with corresponding clamping components or connecting components, thereby facilitating the installation and fixation of the vehicle-mounted navigation equipment such as mobile phones, tablet computers or central control screens. At the same time, since the ball joint 11 is adopted for connection, the bracket seat 51 can be omnidirectionally adjusted, thereby meeting the requirements of different viewing angles of the vehicle-mounted navigation equipment. The ball joint 11 is locked on the bracket seat 51 by the locking nut 52, thereby fixing the angle between the bracket base 1 and the bracket seat 51.

[0027] In summary, the utility model discloses a second threaded section of double -end screw is set up the adjusting block, through adjusting block and press the hinge piece between the first threaded section and adjusting block, again through the cooperation of first threaded section and first threaded hole and rotate, promote the hinge piece to rotate around the hinge position to open the hinge piece, form the tension, and the CD mouth support and the inner wall of CD mouth firmly embed.

[0028] The above only is the preferred embodiment of the utility model and does not limit the utility model, and any modification, equivalent replacement and improvement etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
