[0020] like Figures 1 to 7 As shown, in one embodiment of the utility model, the screen bracket with telescopic and joint structure includes a bracket body 1 and a screen support 2.

[0021] The bracket body 1 includes an outer tube 3, a first telescopic supporting foot 4 and a second telescopic supporting foot 5. Two storage chambers 31 are separated along the length direction inside the outer tube 3, which are parallel to each other and have opposite outlets. The two storage chambers 31 are used to store the first telescopic supporting foot 4 and the second telescopic supporting foot 5 respectively. The head ends of the first telescopic supporting foot 4 and the second telescopic supporting foot 5 are provided with a first telescopic joint assembly 6 that is slidably connected to the storage chamber 31. The first telescopic supporting foot 4 and the second telescopic supporting foot 5 both include at least two coaxially arranged inner tubes 8 with gradually decreasing diameters, wherein the head end of the inner tube 8 with a smaller diameter is provided with a second telescopic joint assembly 7 that is slidably connected to the inner cavity of the inner tube 8 with a larger diameter. The first telescopic joint assembly 6 and the second telescopic joint assembly 7 are provided with an angle limiting shoulder 9, and the angle limiting shoulder 9 is used to limit the rotation angle of the first telescopic joint assembly 6 and the second telescopic joint assembly 7.

[0022] A rotation angle adjustment mechanism and a buckle 21 are provided on the screen support 2. The screen support 2 is rotatably connected to the outer tube 3 through the rotation angle adjustment mechanism. The rotation angle adjustment mechanism is a prior art. For example, an existing rotation angle adjustment mechanism includes a knob screw and a rotating part. The rotating part is rotatably connected to the outer tube 3. The angle of the screen support 2 can be adjusted by the rotating part. The knob screw passes through the rotating part and is threadedly connected to the rotating part. After the angle of the rotating part is adjusted, the knob screw is tightened to make it rest against the surface of the outer tube 3, thereby increasing the friction between the rotating part and the outer tube 3 to achieve a locking effect. The buckle 21 is used to place the screen. The buckle 21 includes a first buckle 211 and a second buckle 212. The first buckle 211 is arranged on both sides of the top of the screen support 2. The first buckle 211 is "L" shaped and can allow the screen to pass through. The second buckle 212 is arranged on both sides of the bottom of the screen support 2. The second buckle 212 is provided with a groove for supporting the lower edge of the screen. The screen support 2 can be but is not limited to placing the screen of electronic products. It can place tablets, laptops, monitors, mobile phones, televisions, digital photo frames, e-books, books and other items suitable for installation and viewing on the bracket.

[0023] When the utility model is in use, the first telescopic supporting leg 4 and the second telescopic supporting leg 5 can be pulled out from the two storage chambers 31, the first telescopic joint assembly 6 can be pulled outward from the storage chamber 31, each inner tube 8 can be stretched, and the second telescopic joint assembly 7 can be pulled outward from the inner cavity of the inner tube 8. At this time, the first telescopic joint assembly 6 and the second telescopic joint assembly 7 can be rotated, so that each section of the inner tube 8 of the first telescopic joint assembly 6 and the second telescopic joint assembly 7 can be bent into a shape suitable for use. For example, the first telescopic joint assembly 6 and the second telescopic joint assembly 7 are bent at an angle of 90° to the outer tube 3 respectively, and the smaller-diameter inner tube 8 is bent at an angle of 70° to the larger-diameter inner tube 8. The bracket body 1 is placed on a bed or other flat surface, and the screen is placed on the buckle 21 of the screen support 2. The user can use the screen in the space reserved between the first telescopic supporting leg 4 and the second telescopic supporting leg 5.

[0024] Optionally, the first telescopic joint assembly 6 includes a first hinge 61, a first fixed portion 62 and a first sliding portion 63, the first fixed portion 62 and the first sliding portion 63 are respectively fixed to the two ends of the first hinge 61, the first fixed portion 62 is fixedly connected to the inner cavity of the inner tube 8, and the first sliding portion 63 is provided with an inner tube end cover 10 slidably connected to the storage cavity 31. The second telescopic joint assembly 7 includes a second hinge 71, a second fixed portion 72 and a second sliding portion 73, the second fixed portion 72 and the second sliding portion 73 are respectively fixed to the two ends of the second hinge 71, the second fixed portion 72 is fixedly connected to the inner cavity of the inner tube 8 with a smaller diameter, and the second sliding portion 73 is provided with an inner tube end cover 10 slidably connected to the inner cavity of the inner tube 8 with a larger diameter. The angle limiting shoulder 9 of the first hinge 61 is set with a 90° limiting surface, and the angle limiting shoulder 9 of the second hinge 71 is set with a 110° limiting surface. When the first fixed part 62 rotates around the center of the first hinge 61, the minimum angle between the first telescopic joint assembly 6 and the second telescopic joint assembly 7 and the outer tube 3 is 90°. When the second fixed part 72 rotates around the center of the second hinge 71, the minimum angle between the inner tubes 8 is 70°.

[0025] Optionally, an outer tube end cap 20 is provided at one end of the two receiving chambers 31 away from the outlet; a circular magnet 30 is installed on the end surface of the first fixing portion 62 and the second fixing portion 72; and a connecting screw 40 which can be attracted by the circular magnet 30 is provided on the inner tube end cap 10 and the outer tube end cap 20. When the first telescopic support leg 4 and the second telescopic support leg 5 are retracted, the connecting screw 40 on the inner tube end cap 10 and the outer tube end cap 20 can be attracted together with the circular magnet 30 to prevent each inner tube 8 from sliding out freely.

[0026] Optionally, the first fixing portion 62 , the second fixing portion 72 and the side wall of the inner tube 8 are connected by fixing screws 50 .

[0027] Optionally, a bushing 60 is provided at the outlet end of the receiving cavity 31 and the inner tube 8 , and the outer wall of each inner tube 8 is slidably connected to the bushing 60 .

[0028] Optionally, a tail handle 70 is provided at the tail ends of the first telescopic supporting leg 4 and the second telescopic supporting leg 5 .

[0029] The working principle of the screen bracket is:

[0030] The first telescopic support leg 4 and the second telescopic support leg 5 include a plurality of inner tubes 8 of different calibers which are sleeved together. When needed, the first telescopic support leg 4 and the second telescopic support leg 5 are extended and used in conjunction with the first telescopic joint assembly 6 and the second telescopic joint assembly 7. Each section of the inner tube 8 can be bent into a shape suitable for use and placed on a bed or other flat surface. After the screen is installed, the angle of the screen support 2 is adjusted downward by the rotating member, and the user can conveniently use the screen fixed on the bracket in the space reserved in the middle to meet the needs of a supine person; when not in use, the first telescopic joint assembly 6, the second telescopic joint assembly 7, the first telescopic support leg 4 and the second telescopic support leg 5 are retracted and stored without taking up space; the first telescopic support leg 4 and the second telescopic support leg 5 can be combined into brackets of different shapes and sizes by using pipes and hinges of different numbers, materials and shapes to meet the needs of users of different heights and weights, and to withstand the weight of loads such as screens or books of different sizes and weights.

[0031] It should be understood that all the above embodiments are illustrative rather than restrictive, and any modifications, equivalent changes and modifications made by those skilled in the art to the specific embodiments described above under the conception of the present invention are still within the scope of the technical solution of the present invention.
