[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] 1. The shaft connection structure of the foldable electronic product is equipped with a metal connecting piece, a bearing and a shaft. When in use, the shaft can rotate inside the bearing, and the shaft drives the first electronic product housing to rotate together through the metal connecting piece, so that the angle between the first electronic product housing and the second electronic product housing can be adjusted to realize the folding function of the electronic product;
[0014] 2. The shaft connection structure of the foldable electronic product is equipped with a first installation outer tube, a limiting ring, a fixing spring, a connecting rod and a spherical clamping block.

[0015] 3. The shaft connection structure of the foldable electronic product is installed with balls for use. Multiple groups of balls are in contact with the outside of the shaft, which can position and support the shaft. When the shaft rotates, the multiple groups of balls can be forced to rotate inside the ball groove. The rotation of the shaft can be assisted by the multiple groups of balls, so that the shaft can rotate along the axis, thereby making the rotation of the shaft more stable.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] See also Figure 1-4 The utility model provides an embodiment: a rotating shaft connection structure of a foldable electronic product, comprising a first electronic product housing 1, a first mounting outer tube 3, a second electronic product housing 4, a second mounting outer tube 5 and a rotating shaft 7, the first mounting outer tube 3 is mounted on the top of one end of the second mounting outer tube 5, and the inner side of the first mounting outer tube 3 is evenly provided with limited circular grooves 8, six groups of limited circular grooves 8 are provided, and the angle between two adjacent groups of limited circular grooves 8 is sixty degrees, and the spherical clamping block 13 is clamped into different limited circular grooves 8, so that the first electronic product housing 1 and the second electronic product housing 4 can be connected. The electronic product shells 4 are adjusted to different angles, a second mounting outer tube 5 is installed at the bottom of the second electronic product shell 4 near one end of the first mounting outer tube 3, and a bearing 6 is installed at the bottom of the second mounting outer tube 5, a rotating shaft 7 is installed inside the bearing 6, and a limiting ring 9 is installed on the top of the rotating shaft 7, a metal connecting piece 2 is installed on the outside of the rotating shaft 7, and the first electronic product shell 1 is installed on the end of the metal connecting piece 2 away from the second electronic product shell 4, and a corrosion-resistant layer is provided on the outside of the metal connecting piece 2, which is beneficial to prolonging the service life of the metal connecting piece 2.
[0023] like Figure 1-3As shown, a mounting groove 11 is provided on the outer side of the limiting ring 9, and a fixing spring 10 is installed inside the mounting groove 11, a connecting rod 12 is installed on the end of the fixing spring 10 away from the limiting ring 9, and a spherical clamping block 13 is installed on the end of the connecting rod 12 away from the fixing spring 10, and an anti-rust layer is provided on the outer side of the fixing spring 10. After the first electronic product shell 1 and the second electronic product shell 4 are rotated to a specified angle, the elastic action of the fixing spring 10 pushes the spherical clamping block 13 to move through the connecting rod 12, and the spherical clamping block 13 can be inserted into the limiting groove 8 corresponding to the inner side of the first mounting outer tube 3. The limiting ring 9 can be limited by the spherical clamping block 13, so as to achieve a limiting effect, thereby preventing the first electronic product shell 1 and the second electronic product shell 4 from rotating at will, and the limiting effect is good.
[0024] like Figure 1-4 As shown, the inner side of the second mounting outer tube 5 is evenly provided with ball grooves 15, and balls 14 are installed inside the ball grooves 15, and the outer sides of the balls 14 are provided with wear-resistant layers. Multiple groups of balls 14 are in contact with the outer side of the rotating shaft 7, which can play a role in positioning and supporting the rotating shaft 7. When the rotating shaft 7 rotates, the multiple groups of balls 14 can be forced to rotate inside the ball grooves 15. The rotation of the rotating shaft 7 can be assisted by the multiple groups of balls 14, so that the rotating shaft 7 can rotate along the axis, thereby making the rotation of the rotating shaft 7 more stable.
[0025] Working principle:
[0026] When in use, the user rotates the first electronic product housing 1 or the second electronic product housing 4 to make the rotating shaft 7 and the first mounting outer tube 3 rotate relative to each other;
[0027] During the rotation process, when the spherical clamping block 13 on the limiting circular ring 9 moves to the position facing the limiting circular groove 8, the elastic action of the fixing spring 10 pushes the spherical clamping block 13 to move through the connecting rod 12, and the spherical clamping block 13 can be clamped into the limiting circular groove 8. The spherical clamping block 13 has a limiting effect on the limiting circular ring 9, which can generate resistance to the rotation of the rotating shaft 7 and the first mounting outer tube 3, and thus has a fixing effect, so that the first electronic product housing 1 and the second electronic product housing 4 can be fixed;
[0028] When rotating again, the user can apply force to the first electronic product housing 1 or the second electronic product housing 4, so that the limiting ring 9 and the first mounting outer tube 3 rotate relative to each other, so that the inner wall of the limiting circular groove 8 can generate an extrusion force on the spherical block 13, that is, the spherical block 13 can be squeezed into the mounting groove 11, and the spherical block 13 can be taken out from the limiting circular groove 8, so that the first mounting outer tube 3 and the limiting circular ring 9 can continue to rotate, and the angle between the first electronic product housing 1 and the second electronic product housing 4 can be adjusted;
[0029] During the rotation process, multiple groups of balls 14 are in contact with the outer side of the rotating shaft 7, which can position and support the rotating shaft 7. When the rotating shaft 7 rotates, multiple groups of balls 14 can be forced to rotate inside the ball groove 15. The rotation of the rotating shaft 7 can be assisted by multiple groups of balls 14, so that the rotating shaft 7 can rotate along the axis, thereby making the rotation of the rotating shaft 7 more stable.
