DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-Figure 4 As shown, the utility model provides a height-adjustable portable bracket, including two mounting seats 1 and two supporting plates 23, wherein two first connecting grooves 3 are provided in the mounting seat 1, and a plurality of positioning grooves 2 are further provided in the mounting seat 1 between the two first connecting grooves 3, a second connecting groove 4 is provided in the supporting plate 23, and a first sliding groove 5 is further provided in the supporting plate 23 located on one side of the second connecting groove 4, a first supporting rod 7 is axially connected in the second connecting groove 4, a positioning block 8 is fixedly installed at one end of the first supporting rod 7 away from the supporting plate 23, and two connecting rods 6 are provided between the two supporting plates 23. The two connecting rods 6 are cross-axially connected at the center position, and one end of the two connecting rods 6 is rotatably installed in the corresponding axial holes in the supporting plate 23, and the other ends of the two connecting rods 6 are slidably installed in the corresponding first sliding groove 5 through the T-shaped axis. The two supporting plates 23 are movably installed on the corresponding mounting seats 1, and a height adjustment mechanism 9 is provided at the lower end of the mounting seat 1. The height adjustment mechanism 9 includes a bottom rod 10 and two second support rods 11. The bottom rod 10 and the two second support rods 11 are movably connected to each other, and one end of the two mounting seats 1 is movably installed in the corresponding first connecting groove 3.

[0022] like Figure 2 , Figure 4 As shown, mounting holes 12 are provided on both sides of the first connecting groove 3, the second support rod 11 is in a U-shaped structure, a first fixed shaft 13 is fixedly installed at one end of the second support rod 11, a second fixed shaft 14 is fixedly installed at the other end of the second support rod 11, a clamping groove 15 is provided on the outer side of the second fixed shaft 14, and both ends of the first fixed shaft 13 are rotatably installed in the corresponding mounting holes 12, that is, the second support rod 11 is rotatably installed in the corresponding first connecting groove 3 through the first fixed shaft 13 at one end, and the height of the entire bracket can be quickly increased by the cooperation of the two second support rods 11 and a bottom rod 10;

[0023] like Figure 1-Figure 2As shown, two connecting seats 16 are fixedly installed at one end of the two supporting plates 23, and the two connecting seats 16 are rotatably installed on the first fixed shaft 13 in the corresponding first connecting groove 3. The supporting plate 23 is rotatably installed on the first fixed shaft 13 through the connecting seats 16, and the angle of the supporting plate 23 can be adjusted by cooperating with the setting of the first support rod 7 and the positioning block 8;

[0024] like Figure 1-Figure 4 As shown, two second slide grooves 17 are provided in the bottom rod 10, and a mounting groove 18 is provided at the top of the second slide groove 17. Rotation grooves 19 are provided on both sides of the mounting groove 18. An adjusting block 20 is also movably installed in the mounting groove 18. The two ends of the bottom rod 10 are respectively inserted and installed on the corresponding second fixed shaft 14 through the second slide grooves 17, that is, one end of the two second support rods 11 is inserted and connected through the bottom rod 10. Through the setting of the bottom rod 10, the supporting angles of the two second support rods 11 can be adjusted synchronously, and the storage of the two second support rods 11 is convenient. A third fixed shaft 21 is fixedly installed at one end of the adjusting block 20, and a clamping block 22 is fixedly installed at the other end of the adjusting block 20. The two ends of the third fixed shaft 21 are respectively rotatably installed in the corresponding rotation grooves 19, and the adjusting block 20 is rotatably installed in the mounting groove 18 through the third fixed shaft 21. Through the setting of the adjusting block 20 and the clamping block 22, the clamping block 22 can be clamped into the clamping groove 15, thereby limiting the unfolded second support rod 11.

[0025] It should be noted that the utility model is a convenient bracket with adjustable height. When in use, the two mounting seats 1 can be manually pulled apart to one side, so that the two mounting seats 1 can respectively drive the corresponding supporting plates 23 to move to one side through the first fixed shaft 13 in the first connecting groove 3 and the connecting seat 16. Then, the two supporting plates 23 unfold the two cross-connected connecting rods 6, and the friction between the two cross-connected connecting rods 6 can be used to limit the distance between the two supporting plates 23. Subsequently, according to the use angle, one end of the two first support rods 7 can be rotated in the corresponding second connecting groove 4, and the positioning blocks 8 at the other ends of the two first support rods 7 can be respectively inserted into the corresponding positioning grooves 2, so that the two first support rods 7 can be used to support the supporting plates 23 at an angle;

[0026] Afterwards, the height adjustment mechanisms 9 at the lower ends of the two mounting seats 1 can be pulled down respectively. Thus, while the height adjustment mechanism 9 moves downward from the lower end of the mounting seat 1, the second slide grooves 17 on both sides cooperate with the second fixed shaft 14 to synchronously move one end of the two second support rods 11 obliquely downward. Thus, the two second support rods 11 respectively rotate in the corresponding first connecting grooves 3 with the first fixed shaft 13 at one end as the axis. After the second fixed shaft 14 at one end of the second support rod 11 moves to one side of the second slide groove 17, the adjusting block 20 can rotate in the mounting groove 18 with the third fixed shaft 21 as the axis, and the clamping block 22 at the other end of the adjusting block 20 is clamped in the clamping groove 15, so that the second fixed shaft 14 can be limited in position, thereby fixing the state of the bottom rod 10 and the two second support rods 11, thereby raising the height of the two mounting seats 1.
