DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-4, the present utility model provides a technical solution: a foldable touch screen, which includes a connecting bridge 1. A first folding frame 2 and a second folding frame 3 are symmetrically installed on the connecting bridge 1. Placement grooves 4 are provided on the upper surfaces of both the first folding frame 2 and the second folding frame 3. A touch display screen 5 is arranged in the placement groove 4. L-shaped grooves 13 are provided at both ends of the lower surface of the connecting bridge 1, and expansion limiting components 9 are arranged in both groups of L-shaped grooves 13; positioning grooves 11 for inserting the expansion limiting components 9 are provided at the lower ends of the opposite sides of the first folding frame 2 and the second folding frame 3. Closing limiting components 6 are arranged at one ends of both sides of the first folding frame 2, and clamping blocks 7 that are clamped with the closing limiting components 6 are fixedly connected to one ends of both sides of the second folding frame 3.

[0022] The closing limiting component 6 includes a connecting strip 91 and multiple groups of inserting rods 96. Insertion holes 94 for slidingly inserting the multiple groups of inserting rods 96 are provided on one side of the connecting strip 91. Springs 97 are sleeved on the outer sides of the multiple groups of inserting rods 96. A positioning insertion plate 92 that is inserted into the positioning groove 11 is fixedly connected to the other side of the connecting strip 91. By the spring 97 pushing against the connecting strip 91, the positioning insertion plate 92 is inserted into the positioning grooves 11 on the first folding frame 2 and the second folding frame 3, improving the stability of the expansion of the first folding frame 2 and the second folding frame 3.

[0023] The multiple groups of inserting rods 96 are all fixedly connected to one side inside the L-shaped groove 13. The multiple groups of inserting rods 96 are arranged at equal intervals, and the multiple groups of inserting rods 96 are all arranged in the same plane. The stability of the positioning insertion rod 96 inserted into the positioning groove 11 is improved through the multiple groups of inserting rods 96 and the springs 97, and further the stability of the positioning of the first folding frame 2 and the second folding frame 3 is improved.

[0024] A right-angle push plate 93 is fixedly connected to the lower surface of the connecting strip 91, and the right-angle push plate 93 is slidably connected to the lower opening of the L-shaped groove 13. Multiple groups of anti-slip lines 95 are provided on the lower surface of the right-angle push plate 93. By pushing the push plate, the connecting strip 91 is driven to compress the spring 97 while the positioning insertion plate 92 is separated from the positioning groove 11, so as to facilitate the folding of the first folding frame 2 and the second folding frame 3, and further facilitate the folding of the touch display screen 5.

[0025] The closing limiting component 6 includes an I-shaped plate 61 and a limiting frame 62. Anti-slip blocks 63 that are slidably connected to both sides of the I-shaped plate 61 are fixedly connected to the lower ends of both sides of the inner cavity of the limiting frame 62. The cross-section of the limiting frame 62 is in a U-shaped setting. An anti-slip-off plate 64 is fixedly connected to the side of the I-shaped plate 61 opposite to the first folding frame 2. The limiting frame 62 slides on both sides of the I-shaped plate 61 through the anti-slip blocks 63, thereby preventing the limiting frame 62 from detaching from the I-shaped plate 61. At the same time, the stability of the movement of the limiting frame 62 is improved through the anti-slip-off plate 64.

[0026] On the opposite sides of the first folding frame 2 and the second folding frame 3, there are fixedly connected with connecting pins 10 that are rotatably connected to the connecting bridge frame 1. The first folding frame 2 and the second folding frame 3 can be flipped by 0 - 90° with the connecting pins 10 as the axes. Through the connecting pins 10, it is convenient for the first folding frame 2 and the second folding frame 3 to be flipped, thus facilitating the folding of the touch display screen 5.

[0027] On the upper surfaces of the first folding frame 2 and the second folding frame 3 at the ends far from each other, there are adhesively bonded with anti - collision strips 8. On the lower surfaces of the first folding frame 2 and the second folding frame 3 at the ends far from each other, there are adhesively bonded with two groups of rubber pads 12. Through the anti - collision strips 8, it is avoided that the touch display screen 5 is damaged by collision after folding, thereby improving the service life of the touch display screen 5.

[0028] When in the unfolded state for use, the limiting frame 62 of the closing limiting component 6 is pushed outwards, so that the limiting frame 62 is separated from the clamping block 7, facilitating the separation of the first folding frame 2 and the second folding frame 3. Then, they are flipped through the connecting pins 10. After the first folding frame 2 and the second folding frame 3 are flipped synchronously by 90 degrees, the positioning groove 11 fits with one end of the L - shaped groove 13. Then, the positioning plug 92 is inserted into the positioning groove 11, improving the stability of the first folding frame 2 and the second folding frame 3 after unfolding and avoiding bending of the touch display screen 5 during use. When in storage, the push plate is pushed, so that the connecting strip 91 compresses the spring 97 on the insertion rod 96, and the positioning plug 92 is retracted into the L - shaped groove 13. After the positioning groove 11 of the first folding frame 2 and the second folding frame 3 is separated from the positioning plug 92, it is convenient for them to be flipped, so that the anti - collision strips 8 on the first folding frame 2 and the second folding frame 3 are in contact with each other, avoiding damage to the touch display screen 5 after folding. Then, the limiting frame 62 is clamped with the clamping block 7, thereby improving the stability of the first folding frame 2 and the second folding frame 3 after folding and enhancing the protection effect on the touch display screen 5.

[0029] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
