Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-5, for the foldable support 100 provided by the present invention, the foldable support 100 can be applied to existing notebook computers of various sizes for use, and used as a keyboard and a screen angle adjustment and support for the notebook computer, so as to provide a stable support for the notebook computer, and can lift up the keyboard of the notebook computer by a certain angle, so that it meets the requirement of human engineering. Meanwhile, the foldable support 100 can also be used as a support of a tablet computer, and is used for supporting and placing the tablet computer, so that the requirements of different viewing angles are met, and the tablet computer can be stably supported. The folding support 100 can also be used as a support for ordinary books and magazines, and can be used for supporting books of different sizes when the books are not convenient to hold by hands, so that the books can be read conveniently.

Further, as shown in fig. 1, it is a schematic view of the expanded three-dimensional structure of the foldable support 100 according to the present invention. As shown in fig. 1, the foldable stand 100 includes a first support bar 10, a second support bar 20, and a telescopic assembly 30. The relative angle between the notebook computer, the tablet computer and the book and the desktop is adjusted and fixedly supported by the first support rod 10 and the second support rod 20. And the telescopic assembly 30 is used for moving the first support bar 10 and the second support bar 20 in a horizontal direction toward or toward each other, and the first support bar 10 and the second support bar 20 are folded and unfolded by the telescopic assembly 30. As shown in fig. 2, it is a schematic view of a folded three-dimensional structure of the foldable bracket 100 according to the present invention. The first support rod 10 and the second support rod 20 can be folded into two rectangular rods arranged in parallel through the telescopic assembly 30. The first support bar 10 and the second support bar 20 are horizontally arranged in parallel after being folded. After the first supporting rod 10 and the second supporting rod 20 are folded, the occupied volume is small, the appearance is regular, and the storage is convenient. After first bracing piece 10 and second bracing piece 20 expand through flexible subassembly 30 simultaneously, can be according to the different of the different product sizes of placing, and adjust the distance of relative movement between first bracing piece 10 and the second bracing piece 20 to satisfy the support demand of different products, make the utility model provides a foldable support 100 can be applicable to not unidimensional notebook computer's support and use, improves foldable support 100's suitability. Furthermore, the utility model provides a first bracing piece 10 and second bracing piece 20 all adopt the metal material preparation, can satisfy foldable support 100's bulk strength and rigidity for first bracing piece 10 and second bracing piece 20 still can have sufficient holding power to be used for supporting notebook computer's weight after expanding.
