Description

Technical Field

[0001] This utility model relates to the field of shooting auxiliary equipment technology, and in particular to a support tripod. Background Technology

[0002] Existing support frames generally include a main pole, a mounting base, and legs. The mounting base is slidably fitted onto the main pole, and there are at least three legs, each of which is rotatably connected to the mounting base. In order to enable the rotatable connection between the legs and the mounting base, a rotatable groove for the legs to be installed is often directly opened on the mounting base.

[0003] However, the mounting base is a relatively exposed component during the use of the support leg. Therefore, in existing technologies, the rotating groove is always located on the inside of the mounting base to avoid exposing the rotating groove and affecting the overall aesthetics of the support leg. Directly creating the rotating groove on the mounting base would reduce the structural strength of the entire mounting base. Furthermore, since the rotating groove needs to rotate with the leg, after creating the rotating groove for leg installation on the inside of the mounting base, other components are needed to provide restraint and prevent the leg from easily detaching from the rotating groove. Due to the narrow space inside the mounting base, it is quite difficult to install other components for restraint after the leg is installed in the rotating groove in existing technologies.

[0005] This utility model discloses a support frame, including: a main rod; at least three support legs, each of which has a pivot at one end; and a mounting base, including a shell, an inner liner, and a connecting sleeve. The inner liner is slidably fitted onto the main rod, the shell is fitted onto the inner liner, and the connecting sleeve is located at the bottom of the inner liner. The connecting sleeve and the inner liner form a rotating groove, and the rotating groove is paired with the pivot at one position.

[0006] Optionally, the liner extends toward the main rod and is formed with a flange.

[0007] Optionally, the connecting sleeve is fitted onto the main rod, and the outer peripheral wall of the connecting sleeve is provided with a guide groove that is matched one-to-one with the rotating shaft.

[0028] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0029] This utility model embodiment provides a support bracket, see [link]. Figures 1-5 The system includes: a main rod 10; at least three support legs 20, each support leg 20 having a pivot 21 at one end; and a mounting base 30, which includes a housing 31, an inner liner 32, and a connecting sleeve 33. The inner liner 32 is slidably fitted onto the main rod 10, the housing 31 is fitted onto the inner liner 32, and the connecting sleeve 33 is located at the bottom of the inner liner 32. The connecting sleeve 33 and the inner liner 32 form a rotating groove 34, which is paired with the pivot 21. Each support leg 20 is rotatably connected to the mounting base 30 by the rotation of the pivot 21 within the rotating groove 34.

[0030] The main rod 10 of this embodiment can be a single rod or a telescopic rod. The telescopic rod is composed of multiple interlocking rods, which can extend and retract. Telescopic rods are widely used in the field of shooting auxiliary equipment technology, and will not be described in detail here.

[0031] In this embodiment of the invention, the mounting base 30 is composed of multiple components. Compared to directly creating a rotating groove for the support leg 20 to rotate on a single component, the rotating groove 34 for the support leg 20 to rotate in this embodiment is not directly provided on the outer shell 31. Therefore, the outer shell 31 does not need to be machined with a corresponding rotating groove 34, resulting in higher strength and processing efficiency. The connecting sleeve 33 is located at the bottom of the inner liner 32, and the rotating groove 34 is formed by the connecting sleeve 33 and the inner liner 32. Therefore, when installing the rotating shaft 21 within the rotating groove 34, it is only necessary to initially fix the rotating shaft 21 between the connecting sleeve 33 and the inner liner 32, and the rotating shaft 21 can be installed in place while the connecting sleeve 33 and the inner liner 32 are forming the rotating groove 34. The rotating groove 34 and the rotating shaft 21 are arranged one-to-one, meaning the number of rotating grooves 34 and rotating shafts 21 is the same. Thus, each rotating shaft 21 can be installed in its corresponding rotating groove 34, and each rotating shaft 21 can rotate within the rotating groove 34.

[0032] See Figure 5 In one embodiment, the inner liner 32 extends toward the main rod 10 and is formed with a flange 321. The flange 321 reduces the gap between the inner liner 32 and the main rod 10, thereby reducing the degree of sway between the main rod 10 and the inner liner 32.

[0033] See Figure 3 and Figure 4 In one embodiment, the connecting sleeve 33 is fitted onto the main rod 10. The outer peripheral wall of the connecting sleeve 33 has guide grooves 331 that are one-to-one with the rotating shaft portion 21. The inner liner 32 is provided with limiting posts 322 that extend into each guide groove 331. The limiting posts 322 and the guide grooves 331 form a rotating groove 34. Thus, by the limiting posts 322 extending into the guide grooves 331 to form a rotating groove 34 for the support leg 20 to rotate, the assembly between the connecting sleeve 33 and the inner liner 32 is more compact.

[0034] In one embodiment, the outer casing 31 has a first through-hole 311 that is one-to-one with the rotating shaft 21. The rotating shaft 21 passes through the first through-hole 311 and is installed in the rotating groove 34. Therefore, in this embodiment, it is not necessary to open a rotating groove 34 for the support leg 20 to rotate on the outer casing 31. It is only necessary to open the first through-hole 311 on the outer casing 31 to avoid interference with the rotation of the support leg 20, thereby improving the strength and processing efficiency of the outer casing 31.

[0035] In one embodiment, see Figure 3The outer peripheral wall of the connecting sleeve 33 is provided with a second through-hole 332, and each guide groove 331 is provided with at least two first through-holes 332. Since the connecting sleeve 33 is fitted onto the main rod 10, the outer peripheral wall of the connecting sleeve 33 has a certain curvature. Therefore, at least two first through-holes 332 are provided in the guide groove 331, which facilitates the deformation of the outer peripheral wall between the two first through-holes 332 in the guide groove 331, making it easier for the limiting post 322 to extend into the guide groove 331, and facilitating the tight fit between the connecting sleeve 33 and the inner liner 32.

[0036] In one embodiment, see Figure 3 and Figure 4 Each guide groove 331 is provided with two corresponding limiting posts 322. Thus, the two limiting posts 322 limit both ends of the rotating shaft 21, ensuring that the rotating shaft 21 does not easily detach from the rotating groove 34. Each limiting post 322 has an arc-shaped groove 3221 opening towards the rotating shaft 21. The arc-shaped groove 3221 cooperates with the rotating shaft 21, making the rotation of the support leg 20 through the rotating shaft 21 smoother.

[0037] In one embodiment, the main rod 10 is provided with an anti-rotation groove 11, and the connecting sleeve 33 is provided with a boss 333 that matches the anti-rotation groove 11. Thus, the boss 333 and the anti-rotation groove 11 facilitate positioning between the two.

[0038] In one embodiment, the support bracket provided by this utility model further includes a sleeve 40, on which a mounting ear 41 is provided. One of the mounting ear 41 and the connecting sleeve 33 has a mounting hole, and the other has a protrusion that mates with the mounting hole. See also Figure 2 and Figure 4 The mounting ear 41 is provided with a mounting hole 411, and the connecting sleeve 33 is provided with a protrusion 334 that mates with the mounting hole 411. Thus, the mounting ear 41 can be easily mounted on the connecting sleeve 33 through the mating of the mounting hole 411 and the protrusion 334.

[0039] In one embodiment, see Figure 1 and Figure 2 The support frame provided in this embodiment of the utility model also includes a connecting rod 50. One end of the connecting rod 50 is rotatably connected to the support leg 20, and the other end of the connecting rod 50 is rotatably connected to the main rod 10. Thus, by setting the connecting rod 50, the stability of the entire support frame in the supported state can be increased, and the linkage of each support leg 20 can be realized, that is, each support leg 20 can be deployed and retracted synchronously.

[0040] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
