Description

Technical Field

[0001] This utility model relates to the field of movable support equipment technology, and more specifically, to a tripod structure. Furthermore, this utility model also relates to a support device including the aforementioned tripod structure. Background Technology

[0002] A tripod fixing structure is a mechanical fixing method that uses three supporting legs to form a stable triangle. Its core principle is to use the geometric property that three points determine a plane to achieve quick, stable, and adjustable support for equipment or structures. Due to its strong stability, good adaptability, and easy installation, the tripod fixing structure is widely used in many fields, such as fixing cameras, camcorders, mobile phones, and live streaming equipment to prevent shaking and improve image quality; or providing stable support for measuring equipment such as total stations, levels, and laser rangefinders.

[0003] For tripod fixing structures that are not fixed for extended periods, the design should be space-saving and provide stable support. However, this is only suitable for situations where the supported object is relatively light. When the supported object is heavy, ordinary tripod fixing structures cannot provide stable support.

[0004] In conventional installation, the feet are directly connected and fixed to the bottom fixing components. However, to ensure the flexibility of the foot plate, the universal feet have a certain gap in the fitting structure between the central fixing shaft and the foot plate. Therefore, during the fixing of the moving platform, the fitting gap of the universal feet structure can cause strong shaking, continuous collisions within the internal structure of the feet under the platform, and compromise the reliability of the universal feet.

[0005] Using inclined cable anchors significantly increases the installation space available for the equipment. For typical sports platforms with limited installation space, inclined cable anchors would occupy several times more installation area, requiring additional cable anchor points, resulting in a much more complex structure and significantly increased manufacturing costs.

[0006] In conclusion, improving the support capacity of tripods is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0007] In view of this, the purpose of this utility model is to provide a tripod structure that provides auxiliary support for the main support rod through auxiliary support components, thereby improving the support capacity of the tripod structure.

[0008] Another objective of this invention is to provide a support device that includes the aforementioned tripod structure.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] The core of this utility model is to provide a tripod structure that can improve the stability of the tripod structure by using auxiliary support components in conjunction with the main support rod.

[0032] Another core aspect of this invention is to provide a support device that includes the aforementioned tripod structure.

[0033] It should be noted that the orientation or positional relationship indicated by terms such as "upper", "lower", "front", and "rear" is based on the orientation or positional relationship shown in the accompanying drawings and is only for the purpose of facilitating the description of this application and simplifying the description. It is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0034] This application provides a tripod structure, including: a top plate 1, a main support rod 2, and an auxiliary support assembly 3;

[0035] Among them, top plate 1;

[0036] There are three main support rods 2. The main support rods 2 are rotatably connected to the top plate 1. The end of the main support rod 2 that is away from the top plate 1 is located on the fixed surface.

[0037] The auxiliary support assembly 3 is rotatably connected to the main support rod 2, and the end of the auxiliary support assembly 3 facing away from the main support rod 2 is detachably connected to the fixed surface.

[0038] For details, please refer to the appendix. Figure 1 The top plate 1 has a flat surface that can support certain objects. Three main support rods 2 are rotatably connected below the top plate 1. Normally, the three main support rods 2 can be folded together for easy storage. When a fixed position is required, the three main support rods 2 need to be separated. The three main support rods 2 work together, with the ends of the three main support rods 2 facing away from the top plate 1 positioned on the fixed surface. This allows the tripod structure to be fixed in position. When the mass of the support on the top plate 1 is relatively small, the overall structure is relatively stable, and the tripod structure is in its first state. When the mass of the support on the top plate 1 is large, it will have a certain impact on the stability of the overall structure. Therefore, the auxiliary support components 3 on each main support rod 2 need to be rotated so that the side of the auxiliary support component 3 facing away from the main support rod 2 can be positioned on the fixed surface. In this way, the cooperation between the auxiliary support components 3 and the main support rods 2 can ensure the stability of the structure and improve the support capacity of the tripod structure.

[0039] It should be noted that the main support rod 2 in this application is a cuboid structure and its length cannot be changed. However, the main support rod 2 can also be replaced by a telescopic rod to facilitate the adjustment of the height position of the top plate 1.

[0040] Based on the above embodiment, it also includes inclined plane fixing feet 4, which are located on the side of the main support rod 2 away from the top plate 1. There are three inclined plane fixing feet 4, which are arranged corresponding to the three main support rods 2.

[0041] For details, please refer to the appendix. Figure 1Each main support rod 2 has a corresponding inclined fixed foot 4 at its lower end. The inclined fixed foot 4 is rotatably connected to the main support rod 2. Since the main body of the inclined fixed foot 4 is a plate structure, taking the fixed surface as a horizontal plane as an example, when the lower surface of the inclined fixed foot 4 is attached to the fixed surface, it can fit tightly with the fixed surface. Moreover, the angle between the main support rod 2 and the inclined fixed foot 4 is different depending on the opening range of the main support rod 2. The rotatable connection can facilitate the adjustment of the angle between the two and ensure the stability of the tripod structure.

[0042] Based on the above embodiments, the auxiliary support assembly 3 includes a first auxiliary support rod 5 and a second auxiliary support rod 6. The first auxiliary support rod 5 is rotatably connected to the main support rod 2, and the second auxiliary support rod 6 is detachably connected to the main support rod 2.

[0043] Specifically, the auxiliary support assembly 3 includes two parts, namely the first auxiliary support rod 5 and the second auxiliary support rod 6. The first auxiliary support rod 5 is rotatably connected to the main support rod 2 and can directly play the role of auxiliary support. When the tripod structure is in the first state, the second auxiliary support rod 6 and the first auxiliary support rod 5 are located on different end faces of the main support rod 2. When it is necessary to change the tripod structure from the first state to the second state, the second auxiliary support rod 6 needs to be disassembled and the second auxiliary support rod 6 and the first auxiliary support rod 5 need to be installed on the same side of the main support rod 2. Through the cooperation of the second auxiliary support rod 6 and the first auxiliary support rod 5, the structural stability of the main support rod 2 is improved.

[0044] Based on the above embodiment, the main support rod 2 has a strip-shaped mounting groove in the middle, and the second auxiliary support rod 6 is installed in the mounting groove through a connecting assembly.

[0045] For details, please refer to the appendix. Figure 2 An installation groove is provided at the middle position of the main support rod 2. The installation groove needs to be set along the length direction of the main support rod 2 and runs through the main support rod 2. The first end of the second auxiliary support rod 6 is rotatably connected to the main support rod 2 by bolts, and the connecting component is set in the installation groove. The installation groove is a strip groove, which can adjust the connection position between the second auxiliary support rod 6 and the main support rod 2 when the main support rod 2 is at different separation degrees, reducing the difficulty of operation and improving the structural stability.

[0046] Based on the above embodiment, the first auxiliary support rod 5 is detachably connected to the main support rod 2, and a detachable pad 7 is provided between the first auxiliary support rod 5 and the main support rod 2.

[0047] Specifically, the first auxiliary support rod 5 is also detachably connected to the main support rod 2. In the first state, both the first auxiliary support rod 5 and the second auxiliary support rod 6 are installed along the length of the main support rod 2 using two bolts 8. It should be noted that the main support rod 2 is longer than both the first auxiliary support rod 5 and the second auxiliary support rod 6, which avoids creating a cumbersome structure. The tripod structure is located in the auxiliary... Figure 1 In the first state, the pad 7 may not be placed between the first auxiliary support rod 5 and the main support rod 2, and the tripod is in the attached position. Figure 2 In the second state, the first auxiliary support rod 5 can be disassembled, and a pad 7 can be placed between the first auxiliary support rod 5 and the main support rod 2. Bolts are used to achieve a rotatable connection between the first auxiliary support rod 5, the pad 7, and the main support rod 2, so that the first auxiliary support rod 5 and the second auxiliary support rod 6 are in different planes, and their ends away from the main support rod 2 can be stacked and connected, as shown in the attached figure. Figure 3 The state shown.

[0048] Based on the above embodiment, the main support rod 2 is provided with a threaded hole on the side near the top plate 1, and the pad 7 is detachably installed on the main support rod 2 by means of bolts 8.

[0049] Specifically, several threaded holes are provided along the length of the main support rod 2. The uppermost threaded hole is used to install and position the pad 7 when the tripod structure is in the first state. A threaded hole is provided above the strip groove to cooperate with the strip groove to position the first auxiliary support rod 5 and the second auxiliary support rod 6. The threaded hole at the bottom of the main support rod 2 is used to realize the rotational connection between the first auxiliary support rod 5, the pad 7 and the main support rod 2.

[0050] Based on the above embodiment, the first auxiliary support rod 5 is provided with a mounting plate 9 on the side opposite to the main support rod 2, and the mounting plate 9 is provided with a through hole for positioning the first auxiliary support rod 5.

[0051] For details, please refer to the appendix. Figure 3 The first auxiliary support rod 5 has a mounting plate 9 at its end on the side away from the main support rod 2. The mounting plate 9 is rotatably connected to the first auxiliary support rod 5, and the surface of the mounting plate 9 has a through hole. The mounting plate 9 can be positioned by bolts or nails, thereby indirectly positioning the first auxiliary support rod 5.

[0052] Based on the above embodiment, the end of the first auxiliary support rod 5 facing away from the main support rod 2, the end of the second auxiliary support rod 6 facing away from the main support rod 2, and the mounting plate 9 are connected by bolts 8.

[0053] For details, please refer to the appendix. Figure 2The end of the first auxiliary support rod 5 facing away from the main support rod 2 is connected to the end of the second auxiliary support rod 6 facing away from the main support rod 2. The first auxiliary support rod 5, the second auxiliary support rod 6 and the main support rod 2 can form a stable triangle, which can ensure the structural stability of the auxiliary support assembly 3. In addition, the mounting plate 9 is also set at the end of the first auxiliary support rod 5 and the second auxiliary support rod 6, which can reduce the required parts, simplify the overall structure and reduce production costs.

[0054] Based on the above embodiment, the main support rod 2 and the inclined plane fixed foot 4 are connected by a ball joint.

[0055] Specifically, in the tripod structure, the inclined fixed foot 4 and the main support 2 are connected by a ball joint (also known as a spherical hinge or ball joint), which has the following advantages: strong terrain adaptability; the ball joint allows the foot to rotate arbitrarily in three-dimensional space, and the connection between the legs and the foot is no longer rigid, allowing it to automatically conform to uneven ground such as slopes, steps, soft soil, and rocks, significantly improving stability on complex terrains in the field or city; and rapid leveling; because the ball joint has omnidirectional freedom, the lengths of the three legs do not need to be precisely matched, and pressing the top plate 1 allows the three feet to simultaneously "find the ground" and level. Automatic coplanar design eliminates the need for repeated extension and retraction of outriggers for leveling; mechanical buffering and windproof / tipping resistance, the ball joint structure generates slight rotation to dissipate energy when subjected to wind or impact, reducing rigid impact on the outriggers and gimbal; some patents add elastic washers or hydraulic damping inside the ball socket to further absorb vibration and improve wind resistance and shooting / observation accuracy; simple maintenance and high reliability, the ball joint is mostly a closed ball socket + stainless steel ball head structure with no fine threads inside, and can be flushed or oiled to restore its integrity after mud and sand intrusion; after wear, only one ball head needs to be replaced, and the maintenance cost is lower than that of traditional universal joints or Hooke joints.

[0056] In addition to the tripod structure described above, this utility model also provides a support device that includes the tripod structure disclosed in the above embodiments. For the structure of other parts of the support device, please refer to the prior art, which will not be repeated here.
