DETAILED DESCRIPTION

[0033] In order to enable those skilled in the art to better understand the solution of the utility model, the following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0034] Embodiment 1

[0035] like Figure 1-Figure 7 As shown, a shooting bracket comprises a central tube 1, a telescopic sleeve 2 movably connected to the central tube 1 axially up and down, at least two movable legs 3 rotatably connected to the outer periphery of the central tube 1, and a connecting rod 4. One end of the connecting rod 4 is movably connected to the movable legs 3, and the connection point between the two is a first connection point 51, and the other end of the connecting rod 4 is movably connected to the telescopic sleeve 2, and the connection point between the two is a second connection point 52.

[0036] The connecting line of the first connection point 51 and the second connection point 52 is inclined relative to the central axis of the telescopic sleeve 2, and the distance between the first connection point 51 and the central axis of the telescopic sleeve 2 is greater than the distance between the second connection point 52 and the central axis of the telescopic sleeve 2. Figure 2 As shown in the figure as an example, the central axis of the telescopic sleeve 2 is L1, and the line connecting the first connection point 51 and the second connection point 52 is L2, then L1 extends vertically, and L2 extends obliquely, and it extends obliquely from top to bottom in the direction close to L1. Since the first connection point 51 is located above the second connection point 52, the distance between the first connection point 51 and the central axis of the telescopic sleeve 2 is greater than the distance between the second connection point 52 and the central axis of the telescopic sleeve 2.

[0037] The central tube 1 and the telescopic sleeve 2 are concentrically and coaxially connected inside and outside, and the two can move up and down relative to each other, so that their total length can be lengthened or shortened. At this time, the movable legs 3 move closer to the telescopic sleeve 2 or the movable legs 3 are extended in the direction away from the telescopic sleeve 2. When the movable legs 3 and the connecting rod 4 are retracted close to the central tube 1, the horizontal height of the bottom end of the movable legs 3 is located above the horizontal height of the bottom end of the telescopic sleeve 2. Figure 2 As shown in the figure as an example, the bottom end of the movable support leg 3 is located at the level of the H1 line, the bottom end of the telescopic sleeve 2 is located at the level of the H2 line, and the H1 line is located above the H2 line.

[0038] The shooting bracket of the utility model, when in the folded state, Figure 1As shown, only the bottom of the telescopic sleeve 2 is in contact with the ground, and at this time, all the movable legs 3 are folded outside the telescopic sleeve 2 and do not contact the ground, which is convenient for the transfer of the shooting bracket. When the movable legs 3 are folded, all the movable legs 3 are assembled to form a cavity 30, and the cavity 30 can cover the telescopic sleeve 2 inside, so that its appearance is simple and more beautiful.

[0039] In the expanded state, Figure 5 As shown, the bottom of the telescopic sleeve 2 and the bottom of the movable legs 3 are in contact with the ground, and the shooting bracket can be stably supported on the ground. Since the telescopic sleeve 2 and the central tube 1 are movably connected, when the user lifts the central tube 1 upward, the upper ends of all the movable legs 3 move upward with the central tube 1, and the total length of the central tube 1 and the telescopic sleeve 2 increases. Under the pulling force of the connecting rod 4 and the gravity of the movable legs 3, the lower ends of all the movable legs 3 move toward the center of the telescopic sleeve 2, and the folding operation of the shooting bracket is realized.

[0040] When it is necessary to switch from the folded state to the unfolded state, the bottom end of the telescopic sleeve 2 is supported on the ground. Since the connecting rod 4 is inclined and the center tube 1 is retracted downward into the telescopic sleeve 2, the connecting rod 4 can automatically push the movable support leg 3 to unfold outward, so that the shooting bracket is unfolded until the bottom end of the movable support leg 3 and the bottom end of the telescopic sleeve 2 are in contact with the ground.

[0041] In order to facilitate the switching from the folded state to the unfolded state, a pusher 6 is elastically connected to the lower end of the telescopic sleeve 2. Figure 3 , Figure 7 As shown, the pusher 6 has an inclined driving surface 61, which extends obliquely from top to bottom and from inside to outside. The lower end of the movable leg 3 abuts against the inclined driving surface 61. When the pusher 6 is axially moved by an external force, for this embodiment, when the bottom end of the pusher 6 is supported on the ground, the pusher 6 moves upward, so that the movable leg 3 is driven by the inclined driving surface 61 to open outward.

[0042] Therefore, in the present embodiment, the bottom end of the telescopic sleeve 2 is supported on the ground, which means that the pushing member 6 is supported on the ground.

[0043] In this embodiment, the number of the inclined driving surfaces 61 is the same as the number of the movable legs 3, that is, three. In order to make the pushing member 6 have a better effect of pushing the movable legs 3 outward, the movable legs 3 are provided with a chamfered surface 31 that can abut against the inclined driving surface 61, and the inclination direction of the chamfered surface 31 is the same as the inclination direction of the inclined driving surface 61.

[0044] The push member 6 is elastically connected to the telescopic sleeve 2, and there can be many implementation forms, as long as the push member 6 can be automatically reset after moving upward. In this embodiment, the push member 6 is sleeved with an elastic reset member 62, which pushes the push member 6 in the axial downward direction in the initial state, and the elastic reset member 62 is compressed when the push member 6 contacts the ground.

[0045] The first connection point 51 and the second connection point 52 do not refer to a specific point, but may be two points, a line, or even a surface. The first connection point 51 and the second connection point 52 are only for the convenience of explaining the connection relationship between the connecting rod 4 and the movable support foot 3 and the telescopic sleeve 2, and are not intended to be a specific limitation.

[0046] Specifically, Figure 2 , Figure 6 , Figure 7 As shown, a first rotating shaft 41 is provided at a determined height position of the movable support leg 3, the upper end of the connecting rod 4 is rotatably connected to the determined height position of the movable support leg 3 through the first rotating shaft 41, and the lower end of the connecting rod 4 is rotatably connected to the bottom of the telescopic sleeve 2 through the second rotating shaft 42. The specific position of the first rotating shaft 41 is not limited here, and it can be connected to the connecting rod 4 or to the movable support leg 3, and the specific position of the second rotating shaft 42 is not limited here, and it can be connected to the connecting rod 4 or to the telescopic sleeve 2.

[0047] In order to achieve the inclined setting of the line connecting the first connection point 51 and the second connection point 52 in a smaller space and also for the convenience of processing, the lower end of the connecting rod 4 has a hook portion 43 bent and extended toward the center direction, where the center direction refers to the center axis direction of the shooting bracket.

[0048] Here, the first rotation axis 41 is set at the determined height position of the movable foot 3, which means that the first rotation axis 41 and the movable foot 3 can only rotate relative to each other, but the relative height of the first rotation axis 41 at the movable foot 3 will not change. In this embodiment, the determined height position of the movable foot 3 is 1 / 3-2 / 3 of the height of the movable foot 3 from bottom to top. Preferably, the determined height position of the movable foot 3 is 3 / 5 of the height of the movable foot 3 from bottom to top. With such a setting, the hook portion 43 at the end of the connecting rod 4 is rotatably connected to the bottom of the telescopic sleeve 2, so that the length of the connecting rod 4 is larger, so that the adjustment range of the unfolding of the shooting bracket is larger, that is, the adjustment range of the spacing between adjacent movable feet 3 is larger.

[0049] In this embodiment, the cross section of the movable legs 3 is in an arc shape. When the three movable legs 3 are folded together, they just form a column, and the interior thereof is hollow to form the above-mentioned cavity 30. The telescopic sleeve 2 is located in the cavity 30, the connecting rod 4 is also located in the cavity 30, and the first rotating shaft 41 and the second rotating shaft 42 are also located in the cavity 30, so that the overall appearance in the folded state is simple and beautiful, and there are no uneven parts exposed to the outside world. In order to form a hollow column with equal diameters at the top and bottom, the outer ring of the central tube 1 forms a portion with an increased outer diameter, and the top ends of the three movable legs 3 are rotatably connected to the outer ring of the portion with an increased outer diameter.

[0050] In order to realize the extension and retraction of the central tube 1, the central tube 1 includes a plurality of inner and outer telescopic tube bodies 11, so that the overall height of the central tube 1 can be adjusted by adjusting the overlapping length of the plurality of telescopic tube bodies 11, which makes the use more flexible. The top of the central tube 1 is provided with an adapter end 12 that can be connected to a gimbal, etc., so as to facilitate the use of the shooting bracket with a mobile phone, a camera, etc.

[0051] Embodiment 2

[0052] like Figure 8-Figure 12 As shown, in this embodiment, the pushing member 6 may not be provided. At this time, when the shooting bracket switches from the folded state to the unfolded state, since the connecting line of the first connecting point 51 and the second connecting point 52 is inclined relative to the central axis of the telescopic sleeve 2, and the distance between the first connecting point 51 and the central axis of the telescopic sleeve 2 is greater than the distance between the second connecting point 52 and the central axis of the telescopic sleeve 2, that is, since the connecting rod 4 is inclined and the center tube 1 is retracted downward into the telescopic sleeve 2, the connecting rod 4 can automatically push the movable leg 3 to unfold outward, so that the shooting bracket is unfolded until the bottom end of the movable leg 3 and the bottom end of the telescopic sleeve 2 are both in contact with the ground.

[0053] The other structures are the same as those in the first embodiment and will not be described in detail.

[0054] The above specific implementation modes are used to explain the present invention rather than to limit the present invention. Any modification and change made to the present invention within the spirit of the present invention and the protection scope of the claims shall fall within the protection scope of the present invention.
