[0025] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0026] like Figures 1-5 As shown, the tripod's folding support structure includes a support rod and a connecting mechanism 01 and a locking mechanism 02 respectively disposed at both ends of the support rod. A travel ring 03 is sleeved on one end of the support rod near the connecting mechanism 01. The travel ring 03 is hinged to the connecting ends of the three support legs 04. A stabilizing rod 05 is hinged to the inner side of the support leg 04. The other end of the stabilizing rod 05 is hinged to the end of the support rod near the locking mechanism 02. The movable end of the support leg 04 cooperates with the locking mechanism 02 and is fixed and released through the locking mechanism 02. The locking mechanism 02 is a locking mechanism with a spring locking structure.

[0027] In another embodiment of this utility model, the locking mechanism 02 uses a spring to provide tension, making it tightly fit against the end of the support rod and having a certain stroke in the direction of the support rod. Its implementation method can be referred to... Figure 5 The main body has a mounting shaft extending into the support rod on one side. A spring is sleeved on the mounting shaft and the end has a fixing mechanism that limits the spring. The main body is fixed to the support rod by the fixing mechanism. Without applying external force, the main body is close to the upper edge of the support rod. When an external force is applied (i.e., the main body is pulled outward), the spring is compressed. After the external force is released, the spring exerts force to return the main body to its original position. It engages with the support leg 04 to fix and release the support leg 04.

[0028] In another embodiment of this utility model, the middle section of the support rod is provided with a protrusion that limits the stroke of the stroke ring 03, which blocks the stroke ring 03 as it approaches the locking mechanism 02, preventing the support leg 04 from opening at too large an angle.

[0029] In another embodiment of this utility model, the stroke ring 03 has a locking element, which enables the support leg 04 to form a relatively stable support.

[0030] In another embodiment of this utility model, the movable end of the support leg 04 protrudes to form a limiting flange 41, and the locking mechanism 02 has a limiting groove 21 that cooperates with the limiting flange 41.

[0031] In another embodiment of this utility model, the end of the stabilizer 05 that is hinged to the support rod is recessed to form a receiving groove 51. A spring 52 and a spring block 53 are provided in the receiving groove 51. The spring block 53 has a stroke in the receiving groove 51. The end of the spring block 53 extends out of the receiving groove 51 in its free length.

[0032] In another embodiment of the utility model, the inner side of the supporting leg 04 has a grid-shaped reinforcing structure, which improves the mechanical properties of the supporting leg 04 and prolongs the service life.

[0033] In another embodiment of the utility model, the connecting mechanism 01 is provided with a threaded mounting hole at the end away from the supporting rod.

[0034] In another embodiment of the utility model, the supporting rod is a telescopic rod.

[0035] In use, the outer pull locking mechanism 02, the limiting clamping groove 21 limiting the limiting convex edge 41 is away from the limiting convex edge 41, and the unlocking is realized. After unlocking, the spring 52 in the accommodating groove 51 is released, the elastic block 53 abuts against the supporting rod to drive the stabilizing rod 05 to pop out outward, and at the same time, the stabilizing rod 05 drives the supporting leg 04 to expand, and the supporting leg 04 drives the travel ring 03 to move on the supporting rod, so as to form the stable support of the three supporting legs 04. In addition, in order to ensure the stability of the support, the travel ring 03 is provided with a locking member for fixing the position of the travel ring 03, and the supporting rod is provided with a protrusion for limiting the excessive movement of the travel ring 03.

[0036] After use, the supporting leg 04 is folded, the supporting leg 04 drives the travel ring 03 to move towards the connecting mechanism 01, the stabilizing rod 05 is recovered, the elastic block 53 abuts against the supporting rod, and the spring 52 is forced to contract, so as to provide outward thrust for the next opening. At the same time, the locking mechanism 02 cooperates with the limiting convex edge 41 to realize locking, so as to complete storage.

[0037] The above only describes the preferred embodiments of the utility model, and does not limit the utility model. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
