Figure 2 A schematic diagram of the structure of the tripod in this embodiment when it is retracted, Figure 3 This is a top view of the tripod of this embodiment when it is unfolded. Figure 4 FIG. 1 is a schematic diagram of the exploded structure of the tripod of this embodiment. Figure 1 , Figure 2 , Figure 3 and Figure 4 The present application provides a tripod that can be quickly unfolded, which includes a tripod composed of at least three frames 1. The frames 1 are connected by a power component 2 and can be rotated at an angle relative to the power component 2 to achieve an opening and closing effect.

[0041] In this embodiment, there are three frames 1, which are arranged at intervals of 120°. When the three frames 1 are unfolded, they can form a tetrahedron shape, and the reflective sheets posted on the frames 1 can warn the rear vehicles 4.

[0042] The frame 1 is hingedly arranged on the power component 2, so that the frame 1 can rotate about a certain rotation center in the horizontal direction.

[0043] The tripod also includes an inflatable bag 3 connected to the power component 2. The inflatable bag 3 is also located inside the area enclosed by the three frames 1. The power component 2 has the ability to release a certain gas and can be automatically triggered and release the above gas under specific circumstances. After the gas is released, it enters the inflatable bag 3, so that the volume of the inflatable bag 3 becomes larger after being filled, thereby pushing the three frames 1 on the outside to rotate, so that the tripod is fully unfolded.

[0044] In this embodiment, the power component 2 includes an air filling bottle 21, a trigger hammer 28 and a reset assembly.

[0045] Among them, the trigger hammer 28 includes a base 281 and a protrusion 282, a first vent hole 2821 is opened in the middle of the protrusion 282, and a second vent hole is opened in the middle of the base 281, and the centers of the first vent hole 2821 and the second vent hole are located on the same straight line; the trigger hammer 28 can start the closed mouth of the inflatable bottle 21 after being triggered by an external force, and a vent hole is penetrated through the middle part of the trigger hammer 28, and the bottom end of the vent hole is connected to the inflatable bag 3, and the gas in the inflatable bottle 21 can be transported to the inflatable bag 3 through the first vent hole 2821, the trigger hammer 28 can move up and down along the axial direction of the inflatable bottle 21 and move toward the closed mouth of the inflatable bottle 21 after being triggered and be sleeved in the closed mouth, and the gas in the inflatable bottle 21 flows to the inflatable bag 3 through the vent hole of the trigger hammer 28.

[0046] Among them, the reset assembly includes a sleeve 24, a reset spring 27 and a trigger rod 25, wherein the side wall of the sleeve 24 is provided with a slide groove, and the slide groove has a horizontally arranged limit section 242 and a vertically arranged reset section 241; the reset section 241 and the limit section 242 are interconnected to facilitate the displacement of the trigger rod 25 between the two; the trigger rod 25 includes a trigger part and a limit section, and the limit section is arranged in the slide groove and fixedly connected to the trigger hammer 28. When the limit section of the trigger rod 25 is in the limit section 242, the tripod is in a retracted state, and when the limit section of the trigger rod 25 is in the reset section 241, the tripod is in an expanded state; the reset spring 27 is arranged on the inner side of the sleeve 24 and is located between the trigger hammer 28 and the inflation bottle 21.

[0047] Figure 5 is a schematic diagram of the structure of the power component 2 of this embodiment, Figure 6 Schematic diagram of the structure of the sleeve 24 of this embodiment. Figure 7 FIG. 2 is a schematic diagram of the structure of the trigger hammer 28 of this embodiment. Figure 5 , Figure 6 and Figure 7 The reset section 241 and the limit section 242 are interconnected, and the trigger rod 25 can slide inside the two to change its position; under the action of external force, the limit section of the trigger part of the trigger rod 25 can move from the limit section 242 at the initial position to the reset section 241. When the limit section of the trigger rod 25 enters the reset section 241, the trigger hammer 28 moves toward the inflatable bottle 21 under the elastic potential energy of the reset spring 27 and opens the closed mouth at the bottom of the inflatable bottle 21 through the protrusion 282 on its top. The gas in the inflatable bottle 21 passes through the closed mouth and is transported to the inflatable bag 3 through the first vent hole 2821 and the second vent hole on the trigger hammer 28. Then the inflatable bag 3 receives the gas and gradually expands, pushing the tripod frame 1 to rotate to form a tetrahedron shape.

[0048] In this embodiment, the power component 2 also includes a fixed seat 22, and the peripheral side of the fixed seat 22 is provided with a clamp 23 for connecting the frame 1. The frame 1 is hinged at the clamp 23 through a fixed axis and can rotate around the fixed axis, thereby changing the position angle of the frame 1 and completing the switching between different states of expansion or contraction.

[0049] In this embodiment, the lower part of the gas bottle 21 is fixed to the top of the sleeve 24, and the upper part of the gas bottle 21 is fixed to the inner side of the fixing seat 22, so that the gas bottle 21 is fixed.

[0050] Moreover, the sleeve 24 is provided with a movable hole which passes through from top to bottom, and the inner diameter of the movable hole is not less than the outer diameter of the gas bottle 21 , so that the gas bottle 21 can be sleeved on the inner side of the sleeve 24 .

[0051] Furthermore, a clamping seat 26 is provided on the inner side of the sleeve 24, and the clamping seat 26 is arranged between the sleeve 24 and the gas bottle 21. The clamping seat 26 is embedded in the side wall of the sleeve 24, and the clamping seat 26 can clamp itself by bolts, and at the same time clamp the gas bottle 21 located on the inner side of the clamping seat 26 to avoid displacement and sliding of the gas bottle 21 in the sleeve 24 due to external force.

[0052] In this embodiment, the trigger rod 25 is disposed between two adjacent frames 1 and deviates from the middle position between the two frames 1 . Figure 3 FIG. 2 is a top view of the tripod of this embodiment when it is unfolded. Figure 3 As shown, in the top view of the tripod, the length of the trigger rod 25 from the adjacent frame body 1 in the clockwise direction is less than the length of the trigger rod 25 from the adjacent frame body 1 in the counterclockwise direction; with such an arrangement, when the tripod falls horizontally, after the trigger rod 25 touches the ground, its limiting portion is sufficient to stably move from the limiting section 242 on the sleeve 24 to the reset section 241, so that the trigger hammer 28 is freed from the restriction and driven by the reset spring 27 to quickly move toward the closed opening of the inflation bottle 21 and open the closed opening, so that the gas in the inflation bottle 21 can be transported to the inflation bag 3 through the closed opening, the first vent 2821 and the second vent.
