DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figures 1 to 3 As shown, the adjustable mobile phone holder comprises: a magnifying part 1, which can be placed on a platform, and a magnifying glass 33 is arranged on the magnifying part 1; a three-dimensional adjustment component, one end of which is rotatably connected to the magnifying part 1; a telescopic splint 2, one end of which is rotatably connected to the three-dimensional adjustment component, and the telescopic splint 2 is used to fix the mobile phone; when the three-dimensional adjustment component is working, the relative position of the telescopic splint 2 on the X-axis, Y-axis and Z-axis can be changed.

[0035] The telescopic splint 2 has telescopic and clamping functions, which can realize the clamping and fixing of mobile phones of different models and sizes, making it convenient for users to use mobile phones in a non-handheld state. When the mobile phone is in a fixed state, the magnifying part can be adjusted to be located between the telescopic splint and the user through a three-dimensional adjustment component. The magnifying glass 33 arranged on the magnifying part has the effect of magnifying the mobile phone screen. In this way, the user can view the mobile phone screen on the telescopic splint 2 through the magnifying glass 33, which is convenient for users with poor eyesight to view the mobile phone. By adjusting the three-dimensional adjustment component, the distance and angle between the magnifying glass 33 and the telescopic splint 2 can be adjusted arbitrarily, making it more convenient to use. In addition to clamping mobile phones, the telescopic splint 2 can also be used to clamp tablet computers or other visual electronic devices. Of course, the magnifying glass can also be used as an ordinary magnifying glass, that is, to magnify objects other than mobile phones and other electronic devices.

[0036] In addition, the magnifying part 1 can also be placed on a platform to serve as a fixed component to provide support for the mobile phone. The mobile phone can be clamped and fixed on the telescopic clamp 2, and the user can directly view the mobile phone, which expands the versatility of the mobile phone holder and makes the mobile phone holder suitable for more scenarios.

[0037] The three-dimensional adjustment component includes: a first longitudinal rotating block 3, which is rotatably connected to the side end of the magnifying part 1; a first transverse rotating block 4, which is rotatably connected to the first longitudinal rotating block 3; a stretching component, which is connected to the first transverse rotating block 4, and the other end of the stretching component is rotatably connected to the telescopic clamping plate 2 and can drive the telescopic clamping plate 2 to move forward and backward.

[0038] One end of the stretching component is connected to the telescopic plate, that is, when the stretching component is extended or retracted, it can drive the telescopic splint 2 to move forward and backward. The other end of the stretching component is connected to the first horizontal rotating block 4, and the first horizontal rotating block 4 is movably inserted into the first longitudinal rotating block 3. When the first horizontal rotating block 4 rotates around the connection between it and the first longitudinal rotating block 3, the stretching component can be rotated on the horizontal plane, that is, the angle of the telescopic splint 2 can be changed on the horizontal plane, which is equivalent to changing the relative angle of the mobile phone on the horizontal plane. The first longitudinal rotating block 3 is rotatably connected to the magnifying part 1. When the first longitudinal rotating block 3 rotates around the connection between it and the magnifying part 1, the relative angle of the mobile phone on the vertical plane can be changed, which is equivalent to the mobile phone being able to reach any position in the space within the maximum height that the stretching component can reach, that is, the mobile phone holder can be suitable for more different scenarios, improving the practicality of the mobile phone holder to meet the user's usage needs.

[0039] When in use, first fix the mobile phone on the telescopic splint 2, then push the stretching assembly left and right, so that the first horizontal rotating block 4 can be rotated to change the position of the mobile phone on the horizontal plane, and then pull the stretching assembly forward and backward, so that the first longitudinal rotating block 3 can be rotated around the connection between it and the magnifying part 1, so that the position of the mobile phone on the vertical plane can be adjusted, and finally pull the stretching assembly forward and backward, so that the relative height position of the mobile phone can be changed, and then the mobile phone can reach a suitable position for the user and the adjustment is completed.

[0040] The stretching assembly includes: a sleeve 5, which is connected to the telescopic splint 2, a telescopic cavity 7 is arranged in the sleeve 5, and a plurality of first limit grooves 8 are opened on both inner end surfaces of the telescopic cavity 7; a pull rod 6, which is movably inserted in the telescopic cavity 7 and one end of which is rotatably connected to the magnifying part 1, and an elastic buckle 9 is arranged at one end of the pull rod 6, and the elastic buckle 9 is movably engaged in the corresponding first limit groove 8.

[0041] The pull rod 6 is movably arranged in the sleeve 5 and one end of the pull rod 6 is connected to the magnifying part 1. When the pull rod 6 moves in the telescopic cavity 7, it can drive the magnifying part 1 to move, and then the distance between the magnifying part 1 and the user can be adjusted, and the elastic buckle 9 can be engaged with the corresponding first limit groove 8. When the pull rod 6 is at different depth positions in the telescopic cavity 7, the elastic buckle 9 can be engaged with the first limit groove 8 at different positions, thereby ensuring the stability of the pull rod 6. When it is necessary to adjust the extension length of the pull rod 6, it is only necessary to press the pull rod 6, which can make the elastic buckle 9 disengage from the first limit groove 8 at the current position, so that it can be moved and the purpose of adjusting the extension length of the pull rod 6 can be achieved.

[0042] A second transverse rotating block 10 is disposed at one end of the sleeve 5 , and a second longitudinal rotating block 11 is rotatably connected to the second transverse rotating block 10 , and the second longitudinal rotating block 11 is rotatably connected to the side end of the telescopic clamping plate 2 .

[0043] A second transverse rotating block 10 is provided at one end of the sleeve 5, and a second longitudinal rotating block 11 is rotatably connected to the second transverse rotating block 10. The second longitudinal rotating block 11 is connected to the telescopic splint 2, which is equivalent to being able to adjust the angle of the telescopic splint 2 on the horizontal plane and the vertical plane, further increasing the application range of the mobile phone holder.

[0044] The first longitudinal rotating block 3 and the second longitudinal rotating block 11 are both provided with connecting columns 12, each of which is provided with a first arc-shaped convex strip 13. The enlarged portion 1 and one end of the telescopic clamping plate 2 are both provided with connecting tubes 14, each of which is provided with a first arc-shaped through groove 15. Each connecting column 12 can be rotatably inserted into the corresponding connecting tube 14, and each first arc-shaped convex strip 13 is movably engaged with the corresponding first arc-shaped through groove 15.

[0045] The first arcuate ridge 13 is movably engaged with the first arcuate groove 15. On the one hand, this is to ensure that the connecting column 12 can rotate in the connecting tube 14. On the other hand, the first arcuate groove 15 can provide supporting force for the first arcuate ridge 13, so that the relative positions of the adjusted first longitudinal rotating block 3 and the second longitudinal rotating block 11 and the corresponding connecting tube 14 will not change easily. When it is necessary to adjust the first longitudinal rotating block 3 or the second longitudinal rotating block 11, it is only necessary to apply a rotational force to the first longitudinal rotating block 3 or the second longitudinal rotating block 11. When the rotational force is greater than the supporting force of the first arcuate groove 15 on the first arcuate ridge 13, the connecting column 12 can rotate in the connecting tube 14.

[0046] The first transverse rotating block 4 and the second transverse rotating block 10 are both provided with plug-in columns 16, and each plug-in column 16 is provided with a second arc-shaped convex strip 17. The first longitudinal rotating block 3 and the second longitudinal rotating block 11 are both provided with plug-in holes 18, and each plug-in hole 18 is provided with a second arc-shaped through groove 19. Each plug-in column 16 can be rotatably inserted into the corresponding plug-in hole 18, and each second arc-shaped convex strip 17 is movably engaged with the corresponding second arc-shaped through groove 19.

[0047] The second arc-shaped through groove 19 can provide support force for the second arc-shaped convex strip 17, so that the relative positions of the adjusted first transverse rotating block 4 and the second transverse rotating block 10 in the corresponding plug-in hole 18 will not change easily, thereby ensuring the stability of the first longitudinal rotating block 3 and the second longitudinal rotating block 11. When it is necessary to adjust the first transverse rotating block 4 or the second transverse rotating block 10, it is only necessary to apply a rotational force to the first transverse rotating block 4 or the second transverse rotating block 10. When the rotational force is greater than the support force of the second arc-shaped through groove 19 on the second arc-shaped convex strip 17, the plug-in column 16 can rotate in the plug-in hole 18.

[0048] A first movable groove 20 is longitudinally opened at the lower end of the telescopic splint 2, and second limiting grooves 21 are opened on the end faces of both sides of the first movable groove 20. A longitudinal movable splint 22 is arranged in the first movable groove 20, and a longitudinal elastic buckle 23 is arranged at one end of the longitudinal movable splint 22, and the longitudinal elastic buckle 23 can be engaged with the corresponding second limiting groove 21.

[0049] When the longitudinal movable clamp 22 is pulled, the longitudinal elastic buckle 23 can be disengaged from the current second limiting groove 21, and then the longitudinal movable clamp 22 can be moved in the first movable groove 20, that is, mobile phones of different lengths can be clamped and fixed, further increasing the application range of the mobile phone holder.

[0050] A second movable groove 24 is horizontally opened at the lower end of the telescopic clamp 2, and third limiting grooves 25 are opened on the end faces of both sides of the second movable groove 24. A horizontal movable clamp 26 is arranged in the second movable groove 24, and a horizontal elastic buckle 27 is arranged at one end of the horizontal movable clamp 26, which can be engaged with the corresponding third limiting groove 25.

[0051] When the transverse movable clamping plate 26 is pulled, the transverse elastic buckle 27 can be disengaged from the current third limiting groove 25, and then the transverse movable clamping plate 26 can be moved in the second movable groove 24, that is, mobile phones of different widths can be clamped and fixed, further increasing the application range of the mobile phone holder.

[0052] In the prior art, the clamping force of the mobile phone holder on the mobile phone will increase as the width and length of the mobile phone increase, which can easily cause the mobile phone to be deformed due to excessive force. In the present application, no matter how wide and long the mobile phone is, as long as the transverse movable clamping plate 26 and the longitudinal movable clamping plate 22 are adjusted to the appropriate position, the clamping force of the mobile phone holder on the mobile phone can be ensured to be constant, thereby preventing the mobile phone from being deformed due to increased force.

[0053] A cover plate 28 is disposed on the first movable groove 20 and the second movable groove 24 . Each cover plate 28 is snap-connected to the telescopic clamping plate 2 and its upper end surface is movably pressed against the corresponding transverse movable clamping plate 26 or longitudinal movable clamping plate 22 .

[0054] The cover plate 28 is snap-connected with the telescopic splint 2, and the changed upper end surface can be movably abutted against the transverse movable splint 26 or the longitudinal movable splint 22, so that the transverse movable splint 26 or the longitudinal movable splint 22 will not fall off the telescopic splint 2 during use, thereby ensuring that the mobile phone holder will not fall off during use.

[0055] A baffle 29 is provided on the first longitudinal rotating block 3 . When the first longitudinal rotating block 3 rotates backward to a certain position, the baffle 29 can abut against the side end surface of the enlarged portion 1 , thereby limiting the backward rotation angle of the first longitudinal rotating block 3 .

[0056] A through hole 30 is provided on the telescopic splint 2, a rotating shaft 31 is inserted into the through hole, and a tripod 32 is rotatably connected to the rotating shaft, so that the angle of the tripod 32 can be adjusted, so that the tripod 32 can independently support the telescopic splint 2 even on platforms of different flatness.

[0057] like Figure 2 , 4 As shown in Figures 5 and 6, after the tripod 32 supports the telescopic splint 2, the three-dimensional adjustment component can be adjusted and the telescopic splint can be placed on a platform or the tripod can be used to support the telescopic splint, so that the magnifying glass 33 is located between the mobile phone and the user. The magnifying glass 33 can magnify the mobile phone interface for convenient screen viewing, and the distance between the magnifying glass 33 and the mobile phone can be adjusted by stretching the component, which is equivalent to adjusting the focal length to change the magnification, making it easier for the elderly to use.

[0058] A movable connecting block 34 is provided on the rotating shaft 31, and a tripod 32 is provided on the movable connecting block 34. A connecting hole 35 is opened on the tripod 32, and a plurality of engaging grooves 36 are provided in the connecting hole 35. A plurality of engaging protrusions 37 are provided on the movable connecting block 34, and each engaging groove 36 is movably connected with a corresponding engaging protrusion 37.

[0059] The tripod 32 can rotate on the rotating shaft 31 , so that the angle between the tripod 32 and the rotating shaft 31 can be adjusted. During adjustment, the connecting hole 35 can rotate around the movable connecting block 34 , and the engaging groove 36 slides on the engaging protrusion 37 .

[0060] A plurality of limiting grooves 38 are formed at one end of the rotating shaft 31 , and an elastic limiting piece 39 is provided on the telescopic clamping plate. One end of the elastic limiting piece 39 extends into the through hole and can extend into any one of the limiting grooves 38 .

[0061] When the tripod 32 is rotated longitudinally, the rotating shaft 31 can be driven to rotate. At this time, the elastic limiting sheet 39 can be inserted into another limiting groove 38, so as to ensure that the rotating shaft 31 remains stable after the adjustment is completed.

[0062] A limiting sleeve 40 is movably sleeved on the other end of the rotating shaft 31 , and a plurality of limiting waist grooves 41 are opened on the limiting sleeve 40 . A plurality of limiting inclined strips 42 are arranged on the lower end of the cover plate located on the first movable groove, and each limiting inclined strip 42 is movably engaged with the corresponding limiting waist groove 41 .
