[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0021] Please see Figures 1 to 5 As shown, a free-folding triangular bracket includes an a-side support rod 1, one end of which is rotatably connected to a b-side support rod 2. A storage groove a105 is provided on one side of the b-side support rod 2 corresponding to the a-side support rod 1. A c-side support rod 3 is rotatably connected to the other end of the a-side support rod 1. A storage groove b205 is provided on one side of the a-side support rod 1 corresponding to the c-side support rod 3. An opening 201 is provided on one side of the bottom of the storage groove b205 corresponding to the c-side support rod 3. A baffle 204 is provided vertically upward on the other side of the bottom of the storage groove b205. A fitting groove 104 is provided on one side of the a-side support rod 1 corresponding to the baffle 204.

[0022] like Figure 3 and Figure 5 The connection end of the support rod 1 on side a and the support rod 2 on side b is curved towards the support rod 3 on side c. Both sides of the curved end of the support rod 1 on side a are provided with a rotating shaft a 106. Corresponding to the rotating shaft a 106, there are matching rotating holes b 203 on both sides of one end of the storage groove b 205. The support rod 1 on side a is rotatably connected to the support rod 2 on side b through the rotating holes b 203.

[0023] Both ends of the c-side support rod 3 are curved. The c-side support rod 3 and the a-side support rod 1 are connected by a rotating shaft b 301 on both sides. Corresponding to the rotating shaft b 301, the c-side support rod 3 is provided with a matching rotating hole a 102 on both sides of the inner wall of the storage groove a 105. The c-side support rod 3 is rotatably connected to the a-side support rod 1 via the rotating hole a 102.

[0024] According to the above scheme, such as Figure 2 This utility model provides a storage groove b 205 on one side of the support rod 2 corresponding to the support rod 1 on the a side, so that the support rod 3 on the c side can be stored and hidden inside the support rod 1 on the a side. Similarly, a storage groove a 105 is provided on one side of the support rod 1 on the a side, so that the support rod 1 on the a side can be stored and hidden inside the support rod 2 on the b side. This allows the triangular bracket of this utility model to be folded and folded up, making the triangular bracket of this utility model smaller in size and easier to transport and handle when not unfolded.

[0025] A connecting spring a4 is connected between the other ends of the support rod 1 on side a and the support rod 2 on side b, and a connecting spring b5 is connected between one side of the support rod 1 on side a and one side of the support rod 3 on side c. Both ends of the connecting spring a4 and the connecting spring b5 are provided with connecting seats.

[0026] like Figure 1 , Figure 3 and Figure 4 The connecting seats at both ends of the connecting spring a4 are respectively provided with through grooves a103 on the side near the top of the storage groove a105, so that a connecting rod c is formed at the top of the through groove a103. They are also provided with through grooves b202 on the side near the end of the support rod 1 on the side away from a of the storage groove b205, so that a connecting rod d is formed on the side of the through groove b202. The connecting seats at both ends of the connecting spring a4 are fixedly connected to the connecting rod c and the connecting rod d.

[0027] The connecting seats at both ends of the connecting spring b5 are provided with two spaced through grooves c on one side of the bottom of the receiving groove a 105, so that a connecting rod a 101 is formed between the two through grooves c. Two spaced through grooves d are provided on the support rod 3 on the c side, so that a connecting rod b 302 is formed between the two through grooves d. The connecting seats at both ends of the connecting spring b5 are fixedly connected to the connecting rod a 101 and the connecting rod b 302.

[0028] According to the above scheme, this utility model connects a connecting spring a 4 between one end of the support rod 1 on side a and one end of the support rod 2 on side b, and connects a connecting spring b 5 between one side of the support rod 1 on side a and one side of the support rod 3 on side c, so that the structure of the triangular support rod 1 on side a, the support rod 2 on side b and the support rod 3 on side c is more stable and firm.

[0029] When the triangular bracket of this utility model needs to be unfolded for support, the gap between the support rod 1 on side a and the support rod 2 on side b should be opened as large as possible. Then, the support rod 3 on side c should be rotated so that its bottom end touches one side of the blocking plate 204. After that, the support rod 1 on side a and the support rod 2 on side b should be released. The support rod 1 on side a and the support rod 2 on side b will rebound and move closer together under the rebound action of the connecting spring a4. Under the rebound action of the connecting spring a4, the support rod 3 on side c can be inclined and fixed between the support rod 1 on side a and the support rod 2 on side b by the rebound force, thereby fixing the triangular structure of the triangular bracket and making the structure of the triangular bracket more stable and firm.

[0030] When the tripod needs to be folded and retracted, the gap between the support rod 1 on side a and the support rod 2 on side b should be widened as much as possible. The support rod 3 on side c will be pulled back into the storage slot a 105 by the rebound action of the connecting spring b 5. The tripod can be quickly folded and retracted by rotating the support rod 1 on side a into the storage slot b 205.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
