[0026] like Figures 1 to 2 As shown, a portable folding stand includes a stand body, which can stably support items with plate-like structures such as drawing boards, solar panels and billboards. It has a wide range of applications and can infinitely adjust the support angle, which can improve the user experience and expand the application potential in various fields. At the same time, it can be folded and stored for easy carrying. The stand body of this embodiment includes a support frame 1 and a support frame 2, wherein one end of the support frame 1 and the support frame 2 is provided with an opening, and the ends on both sides of the opening are provided with hinge joints 3. The support frame 1 and the support frame 2 can be hinged to each other through the hinge joint 3, so that the two can be unfolded under the action of the hinge joint 3 to form an angle to support the items, and when not in use, they can also be folded up through the hinge joint 3 to reduce the overall volume of the stand body, making it convenient to carry or store. Moreover, the projection surface of the support frame 1 and the support frame 2 of this embodiment is a "U"-shaped structure, which can not only effectively reduce the overall weight of the bracket body and facilitate carrying, but also make the contact area between the bottom of the support frame 1 and the support frame 2, which are away from each other, and the ground larger when the support frame 1 and the support frame 2 are unfolded to support items, thereby improving the support stability and avoiding sliding when supporting heavy objects.

[0027] The hinged joints 3 of the support frame 1 and the hinged joints 3 of the support frame 2 of this embodiment are hinged to each other. A locking assembly 4 is provided at the position where the hinged joints 3 of the support frame 1 and the support frame 2 are hinged to each other, so that after the support frame 1 and the support frame 2 are unfolded, the locking assembly 4 can lock the two hinged hinged joints 3 to restrict the relative rotation of the two, thereby fixing the unfolding angle of the support frame 1 and the support frame 2, which can improve the supporting stability of the support body; and when the locking assembly 4 is loosened, the unfolding angle of the support frame 1 and the support frame 2 can be adjusted, and then locked after the adjustment is completed, thereby realizing the infinite angle adjustment of the support body of this embodiment, which is convenient for users to adjust the appropriate angle according to personal preference, which can improve the user experience and also expand the applicable scenarios of the support body of this embodiment.

[0028] Furthermore, the bracket body of this embodiment also includes an extension frame 5 with an opening at one end, so that when the supporting frame 1 and the supporting frame 2 are unfolded to support items, the extension frame 5 can extend the length of the supporting frame 1, which can further improve the supporting stability and applicability of the bracket body of this embodiment.

[0029] Specifically, hinge joints 3 are provided at the ends of both sides of the open end of the extension frame 5 of this embodiment, and the extension frame 5 is hinged to the supporting frame 1 and the support frame 2 respectively through the hinge joints 3, so that when the supporting frame 1 and the support frame 2 are unfolded to a certain angle through the hinge joints 3 to support items, the extension frame 5 can be rotatably connected to the top of the supporting frame 1 through the hinge joints 3 and be on the same inclined plane as the supporting frame 1, so that when the bracket body supports long or foldable items, the extension frame 5 can support the top of such items, so that the supported items can be fully unfolded, which not only expands the scope of application of this embodiment, but also improves the support stability of this embodiment.

[0030] like Figures 1 to 3 As shown, the hinged head 3 of this embodiment includes a connecting portion 31 and a hinged portion 32, wherein the connecting portion 31 is a tubular structure, and the installation connection of the hinged head 3 can be achieved by inserting the connecting portion 31 into the end portions on both sides of the open opening of the support frame 1 or the support frame 2 or the extension frame 5; the hinged portion 32 of this embodiment is arranged at the end of the connecting portion 31, and when each hinged head 3 is connected, the end faces of the hinged portion 32 are tightly attached to each other, and the locking assembly 4 of this embodiment is inserted at the center of the end face of the hinged portion 32, so that the hinged portion 32 can be rotated by the locking assembly 4, thereby realizing the mutual hinge connection of each hinged head 3, and then realizing the mutual hinge connection between the support frame 1, the support frame 2 and the extension frame 5.

[0031] Specifically, the locking assembly 4 of this embodiment includes a locking bolt 41 and a locking nut 42, wherein a hinge hole 33 is provided at the center of the end surface of the hinge portion 32, and the locking bolt 41 can be inserted into the hinge hole 33 from the end surface of one side of the hinge portion 32 and pass through the hinge holes 33 of each hinge portion 32 in sequence, so that each hinge portion 32 can be rotated with the locking bolt 41 as the rotating axis, thereby realizing the mutual hinge connection between the support bracket 1, the support frame 2 and the extension frame 5; and the locking bolt 41 passes through the hinge hole 33, and the locking nut 42 is threadedly connected to the end of the locking bolt 41, so that the support bracket 1, the support frame 2 and the extension frame 5 are After the expansion angle of the extension frame 5 is adjusted, the support frame 1, the support frame 2 and the hinge head 3 on the extension frame 5 can be locked by the locking nut 42, so as to fix the expansion angle of the bracket body, thereby improving the support stability of the bracket body; and, after loosening the locking nut 42, each hinge part 32 can be rotated with the locking nut 42 as the rotating axis to adjust the angle of the bracket body, realizing the effect of stepless angle adjustment of this embodiment, so that the user can adjust the support angle according to the different supported items, which not only improves the user experience, but also makes this embodiment applicable to more scenarios.

[0032] Furthermore, the locking nut 42 of this embodiment is a butterfly nut, so that the user can lock or loosen the hinge head 3 by hand, which is convenient for the user to adjust the angle and improve the user experience.

[0033] In addition, if Figure 3 As shown, the end surfaces of the hinge parts 32 of this embodiment that are in contact with each other are provided with anti-slip teeth 34, so that after the expansion angles of the support frame 1, the support frame 2 and the extension frame 5 are locked by the locking nut 42 and the locking bolt 41, the anti-slip teeth 34 on the end surfaces of the two adjacent hinge parts 32 on the bracket body can engage with each other, thereby avoiding the hinge parts 3 from slipping on each other when supporting heavy objects, and improving the support stability of this embodiment; and, the hinge parts 32 of this embodiment are made of plastic material, so when the locking bolt 41 is tightened to lock the hinge parts 3, the surfaces of the hinge parts 32 made of plastic material are in close contact with each other, which can further increase the friction between each other, thereby further improving the stability of the support of the bracket body, and reducing the overall weight of the bracket body, making it easy to carry.

[0034] like Figure 2 As shown, the end of the support frame 1 away from the hinged joint 3 of this embodiment is bent toward the surface of the support frame 1 to form a supporting portion 11, so that the bottom of the supported article can abut against the supporting portion 11, thereby preventing the article from sliding off the bracket body and preventing the bottom of the article from contacting the bottom surface and causing wear.

[0035] like Figure 1As shown, the support frame 1, support frame 2, and extension frame 5 of this embodiment are arranged sequentially from the outside to the inside, and the length and width of the support frame 1, support frame 2, and extension frame 5 decrease in sequence. When the stand body is folded, the support frame 1, support frame 2, and extension frame 5 can be sequentially inserted, thereby further reducing the folded volume and facilitating portability. In other embodiments, the positional relationship between the support frame 1, support frame 2, and extension frame 5 can be arbitrarily set, and the length and width of the support frame 1, support frame 2, and extension frame 5 decrease in sequence from the outside to the inside according to their respective arrangement positions, thereby also achieving the same support and folding effects.

[0036] The supporting frame 1, support frame 2 and extension frame 5 of this embodiment are all metal frames, which can increase the service life of the bracket body. In addition, the frame structure also effectively reduces the overall weight of the bracket body, making it easier for users to carry.

[0037] In summary, the working principle of this embodiment is as follows: this embodiment provides a supporting frame 1 and a supporting frame 2 with an opening at one end, and provides a hinge joint 3 at the ends of the supporting frame 1 and the supporting frame 2 on both sides of the opening, so that the supporting frame 1 and the supporting frame 2 can be hinged through the hinge joint 3, and then the bracket body composed of the supporting frame 1 and the supporting frame 2 can be unfolded or folded through the hinge joint 3, which is convenient for carrying and storing outside; and, this embodiment provides a locking assembly 4 at the hinge position of the hinge joint 3 of the supporting frame 1 and the supporting frame 2, so that when the supporting frame 1 and the supporting frame 2 are unfolded through the hinge joint 3, the locking assembly 4 can lock the rotation of the hinge joint 3, thereby fixing the unfolding angle of the supporting frame 1 and the supporting frame 2, which is convenient for achieving stable support of the bracket body, and at the same time enables the bracket body to achieve stepless angle adjustment, thereby expanding the applicable scenarios and fields of the bracket body.

[0038] The embodiments described above are only preferred implementation methods of the present invention and cannot be used to limit the scope of protection of the present invention.
