DETAILED DESCRIPTION OF THE EMBODIMENTS

Preferred embodiments of the present invention will be described in detail below in combination with accompanying drawings.

As shown in FIG. 1 and FIG. 2, the present invention provides a phone gravity holder, including a base 10, a pull rod 20 configured to hold the phone, and a left clamping arm 30 and a right clamping arm 40 configured to clamp the phone. The base 10 is provided with a positioning shaft 11, the left clamping arm 30 and the right clamping arm 40 are both mounted on the positioning shaft 11 in a rotatable manner, and the pull rod 20 is respectively in transmission connection with the left clamping arm 30 and the right clamping arm 40, respectively; when the phone is used, the phone is directly placed on the pull rod 20, and under the gravity effect of the phone, the pull rod 20 drives the left clamping arm 30 and the right clamping arm 40 to rotate in reverse to clamp the phone. The phone can be clamped automatically by utilizing the gravity of the phone and simple mechanical principles, the structure is simple, and the production cost is greatly reduced.

Further, the left clamping arm 30 includes a left clamping rod 31 and a first clamping part 32 configured to clamp the phone, the first clamping part 32 is mounted at one end of the left clamping rod 31 in a rotatable manner, and the other end of the left clamping rod 31 is mounted on the pull rod 20 in a rotatable manner through a first connecting rod 51. The right clamping arm 40 includes a right clamping rod 41 and a second clamping part 42 configured to clamp the phone, the second clamping part 42 is mounted at one end of the right clamping rod 41 in a rotatable manner, and the other end of the right clamping rod 41 is mounted on the positioning shaft 11 in a rotatable manner through a second connecting rod 52. Under the gravity effect of the phone, the pull rod 20 drives the left clamping arm 30 and the right clamping arm 40 to rotate in reverse, such that the first clamping part 32 and the second clamping part 42 can be adjacent to each other to clamp the phone.

In the present embodiment, the first clamping part 32 and the second clamping part 42 are both U-shaped clamping blocks. Wherein the U-shaped groove of the U-shaped clamping block is adapted to the side edge of the phone, and the clamping is more stable. The U-shaped clamping block can also be provided with a cushion to protect the phone. Of course, the first clamping part 32 and the second clamping part 42 can also be rollers, the rollers can be rubber rollers, have a buffer effect, and can also protect and clamp the phone.

Further, one end of the first connecting rod 51 is mounted on the left clamping rod 31 in a rotatable manner, the other end is provided with a first gear 61, the first gear 61 is mounted on the pull rod 20 in a rotatable manner, one end of the second connecting rod 52 is mounted on the right clamping rod 41 in a rotatable manner, the other end is provided with a second gear 62, and the second gear 62 is mounted on the pull rod 20 in a rotatable manner and is engaged with the first gear 61. Through mutual engagement of the first gear 61 and the second gear 62, not only the left clamping rod 31 and the right clamping rod 41 can rotate synchronously, but also the shaking of the left clamping rod 31 and the right clamping rod 41 can be reduced. Wherein, the first connecting rod 51 and the second connecting rod 52 have the same length, the left clamping rod 31 and the right clamping rod 41 have the same length, when the pull rod 20 moves for a distance, the left clamping rod 31 and the right clamping rod 41 rotate for the same angle, such that the first clamping part 32 and the second clamping part 42 clamp the phone simultaneously.

Since the left clamping rod 31 and the right clamping rod 41 are mounted on the positioning shaft 11 in a crossed manner, the left clamping rod 31 is closer to the base 10 relative to the right clamping rod 41, under normal conditions, the first clamping part 32 and the second clamping part 42 are not on the same plane, thereby being not beneficial to clamping the phone. Therefore, one end of the left clamping rod 31 for mounting the first clamping part 32 is bent towards the direction far away from the base 10, and one end of the right clamping rod 41 for mounting the second clamping part 42 is bent towards the direction close to the base 10, such that the first clamping part 32 and the second clamping part 42 are arranged on the same plane, thereby being beneficial for clamping the phone.

Since the pull rod 20 is not mounted on the base 10, the pull rod 20 will shake. To solve the problem, the phone gravity holder further includes a third connecting rod 53, a fourth connecting rod 54, a fifth connecting rod 55 and a sixth connecting rod 56, one end of the third connecting rod 53 is provided with a third gear 63, the third gear 63 is mounted on the base 10 in a rotatable manner, the other end of the third connecting rod 53 is connected with one end of the fourth connecting rod 54 in a rotatable manner, the other end of the fourth connecting rod 54 is provided with a fourth gear 64, and the fourth gear 64 is mounted on the pull rod 20 in a rotatable manner. One end of the fifth connecting rod 55 is provided with a fifth gear 65, the fifth gear 65 is mounted on the pull rod 20 in a rotatable manner and is engaged with the fourth gear 64, the other end of the fifth connecting rod 55 is connected with one end of the sixth connecting rod 56 in a rotatable manner, the other end of the sixth connecting rod 56 is provided with a sixth gear 66, the sixth gear 66 is mounted on the base 10 in a rotatable manner and is engaged with the third gear 63. Since the fifth gear 65 is engaged with the fourth gear 64, the sixth gear 66 is engaged with the third gear 63, such that the pull rod 20 can only move up and down, and cannot shake left and right, thereby greatly enhancing overall stability.

In the present embodiment, the third connecting rod 53, the fourth connecting rod 54, the fifth connecting rod 55 and the sixth connecting rod 56 have the same length, thereby ensuring that the pull rod 20 moves up and down along a straight line.

The pull rod 20 includes a fixed plate 21 and a carrying part 22 configured to hold a phone, the fourth connecting rod 54 and the fifth connecting rod 55 are mounted on one side of the fixed plate in a rotatable manner, the carrying part 22 is mounted on the other side of the fixed plate 22, and can move along with the fixed plate 22. The first connecting rod 51 and the second connecting rod 52 are also mounted on the other side of the fixed plate in a rotatable manner, such that the structure is compact, and the first connecting rod 51 and the second connecting rod 52 will not interfere with each other. In consideration of the length of the phone, the fixed plate 21 in FIG. 3 is set to be a short plate. Of course, the fixed plate 21 can also be a long plate, and can be set according to actual requirements.

Further, the phone gravity holder further includes an elastic recovery part (not shown in the figure), and the elastic recovery part is respectively connected with the base 10 and the pull rod 20. During use, the phone is placed on the carrying part 22, the pull rod 20 moves downwards under the gravity effect of the phone, the left clamping rod 31 is driven by the first connecting rod 51 to rotate clockwise, meanwhile, the right clamping rod 41 is driven by the second connecting rod 52 to rotate anticlockwise, such that the first clamping part 32 and the second clamping part 42 are adjacent to each other to clamp the phone. After the phone is taken away, the pull rod 20 moves upwards under the effect of the elastic recovery part, the left clamping rod 31 is driven by the first connecting rod 51 to rotate anticlockwise, meanwhile, the right clamping rod 41 is driven by the second connecting rod 52 to rotate clockwise, such that the first clamping part 32 and the second clamping part 42 are away from each other and recover to the initial state, to wait for the placement of the phone next time. As shown in FIG. 3, in the initial state, the left clamping rod 31 and the right clamping rod 41 are arranged on the same straight line, and the first clamping part 32 and the second clamping part 42 are farthest apart. Wherein the elastic recovery part is preferably spring.

During actual production, the base 10 can be a housing, the left clamping arm 30, the right clamping arm 40 and the pull rod 20 extend out of the housing, and the phone is abutted against the housing, such that the phone can be clamped to use.
