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, legs, and connecting rods. The mounting base is slidably fitted onto the main pole. There are at least three legs, and each leg is rotatably connected to the mounting base. Each connecting rod is paired with a leg, with one end of the connecting rod rotatably connected to its corresponding leg and the other end rotatably connected to the main pole. The connecting rods enable the legs to be extended and retracted in a coordinated manner.

[0003] However, currently, the legs of the support frame need to be manually pried open to unfold each leg to form a support structure, or the mounting base needs to be pushed to slide on the main pole to drive each leg to unfold or retract. When using it, unfolding the legs is quite troublesome. Utility Model Content

[0033] 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.

[0034] This utility model embodiment provides a support bracket, see [link]. Figures 1 to 8The system includes a main rod 10, with a first abutment 11 on its outer peripheral wall; a mounting base 20, which is slidably sleeved on the main rod 10; at least three support legs 30, with one end of each support leg 30 rotatably connected to the mounting base 20; a connecting rod 40, which is paired with a support leg 30, with one end of the connecting rod 40 rotatably connected to its corresponding support leg 30 and the other end of the connecting rod 40 rotatably connected to the main rod 10; and a sleeve 50, which is mounted on the mounting base 20 and slidably sleeved on the main rod. 10. A second abutment 51 is provided at one end of the sleeve 50; an elastic element 52 and a limiting element 53 are provided inside the sleeve 50. The elastic element 52 is slidably sleeved on the main rod 10 and located between the limiting element 53 and the second abutment 51. The limiting element 53 is slidably disposed inside the sleeve 50. A locking mechanism 60 is provided at the bottom of the main rod 10 and is used to lock the other end of each support leg 30 so that it is kept in the closed position. In the closed position, the limiting element 53 abuts against the first abutment 11, and the elastic element 52 is compressed to store energy.

[0035] The main rod 10 of this utility model embodiment can be configured as a single rod or as a telescopic rod, which is composed of multiple interlocking rod sections (see...). Figure 7 The telescopic poles are designed to extend and retract. They are widely used in the field of shooting auxiliary equipment technology, and will not be elaborated upon here.

[0036] See Figure 1 and Figure 2 The connecting rod 40 and the support leg 30 are set one-to-one. That is to say, the number of connecting rods 40 is the same as the number of support legs 30. One end of the connecting rod 40 is rotatably connected to its corresponding support leg 30, and the other end of the connecting rod 40 is rotatably connected to the main rod 10. Thus, the rotatable connection of each support leg 30 on the mounting base 20 can be realized through the connecting rod 40, thereby enabling the simultaneous unfolding of each support leg 30 to form a support structure and the simultaneous closing of each support leg 30 to achieve the closed state of the support frame.

[0037] See Figure 1 and Figure 2 The sleeve 50 is mounted on the mounting base 20, allowing it to slide along the main rod 10 together with the mounting base 20. The locking mechanism 60 locks the other end of each support leg 30 in a closed position. This can be achieved by providing magnets that attract each other at the bottom of the main rod 10 and on the support legs 30, so that the other ends of each support leg 30 can be magnetically attracted and fixed together when they are close to the bottom of the main rod 10. See also... Figure 2In one embodiment, the locking mechanism includes a movable cover 61, a fixed base 62, and a spring (not shown in the figure). The fixed base 62 is disposed at the bottom of the main rod 10. The movable cover 61 is provided with a connecting post 63, which is slidably connected to the fixed base 62. The movable cover 61 is movably mounted on the fixed base 62. The spring is sleeved on the connecting post 63 and abuts against the movable cover 61. One of the movable cover 61 and the support leg 30 is provided with a groove, and the other is provided with a protrusion. Thus, pressing the movable cover 61 allows it to slide towards the main rod 10. As the movable cover 61 slides towards the main rod 10, the protrusion and groove of the movable cover 61 and the support leg 30 separate, thereby releasing the locking mechanism 60 from restricting the support leg 30. The spring is used to reset the movable cover 61 to its unpressed state.

[0038] See Figure 2 When the device is in the closed position, the limiting member 53 abuts against the first abutment 11. At this time, the limiting member 53 cannot continue to slide on the main rod 10, while the sleeve 50 and the second abutment 51 can still continue to slide a certain distance on the main rod 10. During the sliding process, one end of the elastic member 52 is abutted by the limiting member 53 and the first abutment 11, while the other end of the elastic member 52 continues to slide on the main rod 10 with the second abutment 51, thereby compressing the elastic member 52 to store energy (accumulate elastic potential energy). When the locking mechanism 60 is unlocked, that is, the restriction of the locking mechanism on the other end of each leg 30 is released, and the elastic potential energy accumulated by the elastic member 52 is released, thereby pushing the mounting base 20 and the sleeve 50 to slide on the main rod 10, thereby allowing each leg 30 to unfold. The elastic member 52 can be set as a compression spring or other component that can accumulate elastic potential energy, as long as it can compress the elastic member 52 to store energy when the other end of each leg 30 is in the closed position.

[0039] See Figure 2 In one embodiment, the limiting member 53 is slidably sleeved on the main rod 10. The limiting member 53 is used to cooperate with the first abutment 11 to compress the elastic member 52. In other embodiments, the limiting member 53 may also be a slider (not shown in the figure), which is slidably connected to the sleeve 50. In the closed position, the slider abuts against the first abutment 11 and slides within the sleeve 50 to compress the elastic member 52.

[0040] See Figure 3 In one embodiment, the second abutment 51 is integrally formed with the sleeve 50, that is, the second abutment 51 and the sleeve 50 are the same component. Specifically, the second abutment 51 can be formed by multiple protrusions extending from the inner peripheral wall of the sleeve 50. The multiple protrusions are evenly distributed on the inner peripheral wall of the sleeve 50, so that there is no need to install a component with the function of the second abutment 51 on the sleeve 50 separately, thereby reducing the number of assembly components.

[0041] In one embodiment, the second blocking part 51 is sleeved on the sleeve 50 (not shown in the figure), that is to say, the second blocking part 51 and the sleeve 50 are two parts, and the two parts are processed separately to reduce the processing difficulty.

[0042] See Figures 4-6 In one embodiment, the mounting base 20 includes a housing 21, an inner liner 22, and a connecting sleeve 23. The inner liner 22 is fitted onto the main rod 10, the housing 21 is fitted onto the inner liner 22, and the connecting sleeve 23 is disposed at the bottom of the inner liner 22. The connecting sleeve 23 and the inner liner 22 form a rotating groove 24 for the support leg 30 to connect. Thus, the mounting base 20 is composed of multiple parts, which is more conducive to assembly than directly creating a rotating groove for the support leg 30 to rotate on a single part. Furthermore, in this embodiment, the rotating groove 24 for the support leg 30 to rotate is not directly disposed on the housing 21, so the housing 21 does not need to be machined with a corresponding rotating groove 24, thereby increasing the strength and processing efficiency of the housing.

[0043] See Figure 7 In one embodiment, the inner liner 22 extends toward the main rod 10 and is formed with a flange 221. The flange 221 has a first notch 222 through which the first abutment 11 passes. The flange 221 reduces the gap between the inner liner 22 and the main rod 10, thereby reducing the degree of swaying between the main rod 10 and the inner liner 22.

[0044] See Figure 4 In one embodiment, the outer peripheral wall of the connecting sleeve 23 is provided with a guide groove 231, and the inner liner 22 is provided with a limiting post 223 extending into the guide groove 231. The limiting post 223 and the guide groove 231 form a rotating groove 24. Thus, the limiting post 223 extending into the guide groove 231 forms a rotating groove 24 for the support leg 30 to rotate, thereby making the assembly between the connecting sleeve 23 and the inner liner 22 more tight.

[0045] See Figure 4 In one embodiment, a second notch 211 is provided on the outer casing 21 for inserting the support leg 30. Therefore, in this embodiment, it is not necessary to provide a rotation groove 24 on the outer casing 21 for the support leg 30 to rotate. Only the second notch 211 needs to be provided on the outer casing 21 to avoid interference with the rotation of the support leg 30, thereby improving the strength and processing efficiency of the outer casing 21.

[0046] See Figure 2 In one embodiment, a pivot portion 31 is provided at one end of the support leg 30, and two limiting posts 223 are provided, which correspond to the two ends of the pivot portion 31. Thus, the two limiting posts 223 limit the two ends of the pivot portion 31, ensuring that the pivot portion 31 will not easily disengage from the rotating groove 24.

[0047] See Figure 1In one embodiment, the main rod 10 is provided with an anti-rotation groove 12, and the connecting sleeve 23 is provided with a boss 232 that matches the anti-rotation groove 12. Thus, the boss 232 and the anti-rotation groove 12 facilitate positioning between the two.

[0048] See Figure 8 In one embodiment, a holding mechanism 70 is provided at the top of the main rod 10. The holding mechanism 70 is used to fix shooting devices such as mobile phones and tablets.
