DETAILED DESCRIPTION

[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 1-5 The utility model provides a technical solution: a deformation-resistant and high-load-bearing rotating shaft, comprising a rotating shaft body 1, on one side of which an extension component is arranged; the extension component comprises an extension threaded rod 2 fixed on one side of the rotating shaft body 1, on which an extension sleeve 3 is threadedly connected; a connecting sleeve 4 is threadedly connected to the outer side of the extending sleeve 3 through a threaded member, and a clamping assembly is arranged at one end of the connecting sleeve 4 away from the extending sleeve 3; when the length of the rotating shaft body 1 needs to be adjusted, the connecting sleeve 4 is driven to slide during the rotation of the extending sleeve 3, so that the clamping assembly is clamped at a predetermined work position.

[0023] Specifically, the anti-deformation high-load bearing shaft includes a shaft body 1, wherein the shaft body 1 is made of a high-strength alloy material and has a strong hardness. When installed inside a notebook, it has sufficient strength to prevent the shaft body 1 from being deformed and meet work needs. An extension component is provided on one side of the shaft body 1, which can adjust the length of the shaft body 1 according to work needs, further meet the applicable scope of the shaft body 1, and achieve better application effects. The extension component includes an extension threaded rod 2 fixed on one side of the shaft body 1, and an extension sleeve 3 is threadedly connected to the extension threaded rod 2. Therefore, when it is necessary to adjust the length of the shaft body 1, the extension sleeve 3 is driven to rotate on the extension threaded rod 2, thereby driving the extension sleeve 3 to slide, and the state of the shaft body 1 is adjusted according to work needs, and the use effect is better. The outer side of the extension sleeve 3 is threadedly connected with a connecting sleeve 4 through a threaded member. When the extension sleeve 3 rotates, the connecting sleeve 4 is also driven to slide. A clamping assembly is arranged at one end of the connecting sleeve 4 away from the extension sleeve 3, which can drive the clamping assembly to slide and fix the shaft body 1 inside the notebook. At the same time, a card slot adapted to the clamping assembly is provided inside the notebook. The clamping assembly is clamped inside the card slot, and the clamping assembly is limited. Specifically, during use, when the length of the shaft body 1 needs to be adjusted, the extension sleeve 3 drives the connecting sleeve 4 to slide horizontally during the rotation stroke, so that the clamping assembly is clamped at a predetermined position, which is done in one go without adjusting the length of the shaft first. Then, the shaft body 1 is fixed at a predetermined position inside the notebook through the clamping assembly, which simplifies the operation procedure and greatly improves the work efficiency, and is suitable for wide promotion and use.

[0024] In the embodiment provided by the utility model, the clamping assembly includes a clamping frame 6, which is slidably connected to the connecting sleeve 4 through an elastic unit. Therefore, when the length of the rotating shaft body 1 has not been adjusted to a predetermined position and the clamping assembly has been clamped at a predetermined position, the clamping assembly will have a certain buffering effect through the elastic unit to avoid motion interference and meet work needs.

[0025] In the embodiment provided by the utility model, the elastic unit includes a sliding rod 7 fixedly connected to the clamping frame 6, a fixing cap 8 is fixedly connected to the sliding rod 7, a fixing spring 9 is arranged between the fixing cap 8 and the connecting sleeve 4, and the elastic force of the fixing spring 9 drives the clamping frame 6 away from the connecting sleeve 4. Therefore, when the clamping frame 6 is fixed, as the connecting sleeve 4 continues to slide, the clamping frame 6 will drive the sliding rod 7 to slide in the opposite direction, and stretch the fixing spring 9 through the fixing cap 8 to meet the working needs.

[0026] In the embodiment provided by the utility model, the threaded member includes an external thread 5 provided on the outer side of the extension sleeve 3, an internal thread is provided on the inner side of the connecting sleeve 4, and the external thread 5 is threadedly connected with the internal thread to facilitate driving the connecting sleeve 4 to slide.

[0027] In the embodiment provided by the utility model, a first hinge 10 is fixedly connected to one side of the shaft body 1, and a second hinge 11 is installed on a mounting member on a side of the shaft body 1 away from the first hinge 10, so as to facilitate the use of the entire shaft body 1 and meet working needs.

[0028] In the embodiment provided by the utility model, the mounting member includes a mounting plate 12 rotatably connected to the shaft body 1, the mounting plate 12 is connected to the second hinge 11 through a snap-on unit, a damping member 13 is also provided on the shaft body 1, the mounting plate 12 is fixedly connected to the damping member 13, so during use, the second hinge 11 is installed with the damping member 13 through the mounting plate 12, so that a certain damping is generated during the process of unfolding and closing the entire notebook, and the use effect is better.

[0029] In the embodiment provided by the utility model, the snap-in unit includes a protrusion 14 fixedly connected to the mounting plate 12, and a snap-in groove adapted to the protrusion 14 is opened on the second hinge 11, and the protrusion 14 is snap-fitted with the snap-in groove. Therefore, during use, when the second hinge 11 rotates, the mounting plate 12 is driven to rotate through the cooperation between the protrusion 14 and the snap-in groove, and the damping member 13 is driven to rotate through the mounting plate 12, so that the use effect is better.
