TECHNICAL FIELD

[0001] The utility model relates to photographic device field, especially a tripod's supporting device. BACKGROUND

[0002] A tripod is a three-legged support for cameras, video cameras or other equipment, which is usually composed of three supporting rods and a connecting seat. The three supporting rods are detachably installed on the connecting seat to support the ground, and the connecting seat is used to install cameras, video cameras or other photographic devices.

[0050] This application applies to the use of tripods, which typically consist of three legs.

[0051] Reference Figures 1 to 5 This application proposes a tripod support device, comprising:

[0052] Mounting body 1, which is block-shaped and has a first surface plane 101;

[0053] The first mounting structure 2 is disposed on the first surface 101 for mounting one of the three legs; and the second mounting structure 3 is disposed on both sides of the mounting body 1 for mounting the other two of the three legs.

[0054] In this embodiment, the core of the tripod support device of this application lies in the stable installation and support of the three legs of the tripod through a mounting body 1 and its first mounting structure 2 and second mounting structure 3. The mounting body 1, as the basic component of the entire device, has a block-shaped design and a first surface plane 101. The first mounting structure 2 is disposed on the first surface plane 101 and is used to fix one of the three legs of the tripod, while the second mounting structures 3 are distributed on both sides of the mounting body 1 and are used to install the other two legs. This layout, by rationally allocating the fixing points of the legs, forms a triangular support structure, thereby ensuring the overall stability of the tripod.

[0055] First, a support leg is fixed to the first surface 101 of the mounting body 1 via the first mounting structure 2. Since the first surface 101 is a flat surface, the support leg can obtain uniform support force, ensuring its stability.

[0056] Subsequently, the other two legs are installed on both sides of the mounting body 1 via the second mounting structure 3. This symmetrical or rationally distributed design on both sides allows the three legs of the tripod to form a stable triangular support layout in space.

[0057] This application integrates the mounting points of the three legs onto the first surface 101 and both sides of the mounting body 1 through a centralized layout of the mounting body 1, the first mounting structure 2, and the second mounting structure 3. When stored, this design reduces the planar footprint of the support device, making the tripod support device more compact.

[0058] Reference Figure 1 and Figure 2 In some embodiments, the mounting body 1 proposed in this application includes a second surface plane 102 opposite to the first surface plane 101, and a side wall 103 surrounding the first surface plane 101 and the second surface plane 102; the second surface plane 102 is provided with a first caster 8.

[0059] Reference Figure 1 and Figure 3 In some embodiments, the first mounting structure 2 proposed in this application includes:

[0060] The first clamping member 21 has a first clamping opening 210;

[0061] The second clamping member 22 is spaced apart from the first clamping member 21 and has a second clamping opening 220 facing the first clamping opening 210;

[0062] At least one of the first clamping member 21 and the second clamping member 22 is disposed on the first surface plane 101 so that the first clamping jaw 210 and the second clamping jaw 220 move toward or away from each other to clamp or release the branch.

[0063] In this embodiment, the working principle of the first mounting structure 2 is based on the sliding adjustment and clamping force generation of the clamping mechanism. The first clamping member 21 has a first clamping jaw 210, and the second clamping member 22 has a second clamping jaw 220 facing it, together forming an adjustable clamping space. At least one clamping member (the first clamping member 21 or the second clamping member 22) can be slidably mounted on the mounting body 1. By sliding, the distance between the first clamping jaw 210 and the second clamping jaw 220 changes, thereby clamping or releasing the support leg. This design utilizes the principle of mechanical clamping, generating sufficient friction and clamping force through the relative movement between the clamping jaws to ensure that the support leg is firmly fixed.

[0064] Initial adjustment: Before installing the support leg, the first clamp 21 and the second clamp 22 are in a relatively loose state, that is, the distance between the first clamp 210 and the second clamp 220 is relatively large. At this time, by sliding at least one clamp (assuming the second clamp 22 is slidable), the distance between the two clamps is adjusted to be slightly larger than the diameter or width of the support leg.

[0065] Tripod placement: Place one of the tripod legs into the clamping space between the first clamp 210 and the second clamp 220, ensuring that the leg is in contact with the clamp.

[0066] Clamping operation: By manually or with the aid of an auxiliary tool, slide the movable clamping element (e.g., the second clamping element 22) to bring the second clamping jaw 220 closer to the first clamping jaw 210. The two clamping jaws move towards each other, gradually reducing the distance until the support leg is clamped. At this point, the clamping force applied by the clamping jaws to the support leg prevents it from moving or disengaging easily.

[0067] Release process (if disassembly is required): When it is necessary to release the support leg, slide the clamping member in the opposite direction so that the first clamp 210 and the second clamp 220 move in opposite directions, the clamping space increases, and the support leg can be removed.

[0068] The first mounting structure 2 can accommodate legs of different sizes or shapes by sliding and adjusting the clamp spacing. This flexibility makes the design highly versatile and suitable for various tripod models.

[0069] Please continue to refer to Figure 1 and Figure 3 In some embodiments, the first mounting structure 2 proposed in this application further includes:

[0070] The first mounting base 23 is located on one side of the first clamping member 21;

[0071] The first locking member 24 includes a first rod portion 241 and a first handle portion 242 connected to one end of the first rod portion 241. The first handle portion 242 is located on the side of the first mounting base 23 facing away from the first clamping member 21. The middle part of the first rod portion 241 is threaded to the first mounting base 23. The other end of the first rod portion 241 is connected to the second clamping member 22.

[0072] The first handle 242 is used to be driven by external force to move the first rod 241 and drive the second clamping member 22 to move toward or away from the first clamping member 21, so that the second clamping jaw 220 and the first clamping jaw 210 move toward or away from each other.

[0073] In this embodiment, the working principle of the first mounting structure 2 is based on a combination of threaded transmission and lever operation. The first clamping member 21 is fixed to one side of the first mounting base 23, while the second clamping member 22 is moved by the drive of the first locking member 24. The first locking member 24 consists of a first rod portion 241 and a first handle portion 242. The middle part of the first rod portion 241 is threadedly connected to the first mounting base 23, and one end is connected to the second clamping member 22. When an external force is applied to the first handle portion 242, the first rod portion 241 rotates and moves along the threaded axis, causing the second clamping member 22 to slide toward or away from the first clamping member 21, thereby enabling the first clamping jaw 210 and the second clamping jaw 220 to clamp towards each other or release away from each other. This design utilizes the precise adjustment of the thread and the force-saving characteristics of the lever to ensure the controllability and stability of the clamping force.

[0074] Initial adjustment: Before installing the support legs, the first clamp 210 and the second clamp 220 are in the loose state, and the distance between the second clamping member 22 and the first clamping member 21 is relatively large. At this time, the threaded position of the first rod 241 makes the clamping space sufficient to accommodate the support legs.

[0075] Tripod placement: Place one of the tripod legs between the first clamp 210 and the second clamp 220, ensuring that the leg is aligned with the clamp.

[0076] Clamping operation: The user manually rotates the first handle 242 (e.g., clockwise), causing the first rod 241 to advance forward along the thread in the first mounting base 23. Since the other end of the first rod 241 is connected to the second clamping member 22, this pushing action causes the second clamping member 22 to move closer to the first clamping member 21, and the first clamping jaw 210 and the second clamping jaw 220 move towards each other, gradually clamping the support leg until the clamping force is strong enough.

[0077] Release process: If the foot needs to be removed, the user rotates the first handle 242 in the opposite direction (e.g., counterclockwise). The first rod 241 moves backward along the thread, causing the second clamping member 22 to move away from the first clamping member 21. The first clamping jaw 210 and the second clamping jaw 220 move in opposite directions, increasing the clamping space, and the foot can be released and removed.

[0078] The first mounting structure 2, through the introduction of the first mounting base 23 and the first locking element 24, combines threaded transmission with lever drive. Its working principle relies on the conversion of rotational motion into linear clamping force. The process manifests as precise clamping and releasing operations, and the effects are precise adjustment, labor-saving efficiency, stable clamping, and structural durability. This optimized design significantly improves the functionality of the first mounting structure 2, enabling it to better meet the needs of leg fixation in tripod support devices.

[0079] Reference Figure 1 , Figure 4 and Figure 5In some embodiments, the second mounting structure 3 proposed in this application is two, with the two second mounting structures 3 spaced apart on the side wall 103. The second mounting structure 3 includes:

[0080] Pipe component 31, one end of which is connected to the mounting body 1;

[0081] Clamping member 32 is provided at the other end of tube member 31 and is used to clamp the support leg;

[0082] The second caster 33 is installed on the pipe component 31.

[0083] In this embodiment, two second mounting structures 3 are spaced apart on the side wall 103 of the mounting body 1, extending the support points from the mounting body 1 through tubular members 31 to form a spatial distribution. One end of the tubular member 31 is connected to the mounting body 1, and the other end is fixed to the support leg by a clamping member 32 to ensure the stability of the support leg. Second casters 33 are provided on the tubular member 31, providing additional support or movement functions (depending on the specific design of the casters, such as fixed or omnidirectional), thereby enhancing the stability and adaptability of the overall structure. This design expands the support range of the tripod through extension and clamping, and optimizes the function of the contact surface through the casters.

[0084] Initial installation: Two second mounting structures 3 are pre-fixed to the side wall 103 of the mounting body 1. One end of the pipe member 31 is connected to the side wall 103, and the other end is suspended and equipped with a clamping member 32 and a second caster 33. At this time, the clamping member 32 is in the clamping state.

[0085] Leg fixing: Insert or connect the other two legs of the tripod into the clamping members 32 of the two second mounting structures 3 respectively. The clamping members 32 (which may be clamping devices, such as bolt clamps or spring clamps, depending on the details of the embodiment) clamp the legs by mechanical action, so that they are firmly connected to the end of the tube member 31.

[0086] The second caster 33 is located on the tubular member 31 and may directly contact the ground or other supporting surfaces. If the caster is fixed, it provides an additional support point; if it is rotatable or swivel, it allows the tripod to be fine-tuned or moved after installation to adapt to different usage environments.

[0087] Reference Figure 1 and Figure 4 In some embodiments, the pipe component 31 proposed in this application includes a first pipe component 311 and a second pipe component 312. The second pipe component 312 is telescopically disposed inside the first pipe component 311. The first pipe component 311 is connected to the mounting body 1. A clamping component 32 is provided at the end of the second pipe component 312 away from the first pipe component 311.

[0088] In this embodiment, the working principle of the pipe component 31 is based on the length adjustment and end clamping function of the telescopic sleeve structure. The first pipe component 311 is fixedly connected to the mounting body 1, serving as the base of the telescopic mechanism; the second pipe component 312 is telescopically nested inside the first pipe component 311, with a clamping member 32 at its end away from the first pipe component 311 for fixing the support leg. By sliding the second pipe component 312 within the first pipe component 311, the overall length of the pipe component 31 can be dynamically adjusted, thereby changing the distance of the clamping member 32 relative to the mounting body 1. This design utilizes the flexibility of the telescopic mechanism and the fixing ability of the clamping member to achieve variable positioning of the support point and stable installation of the support leg.

[0089] In the initial state, the pipe component 31 is installed on the side wall 103 of the mounting body 1, the first pipe component 311 is fixedly connected to the mounting body 1, and the second pipe component 312 is partially or completely retracted into the first pipe component 311. At this time, the clamping component 32 is located close to the mounting body 1, and the pipe component 31 is relatively short.

[0090] Depending on the tripod's support requirements, the user manually pulls out or pushes in the second tube 312, allowing it to slide within the first tube 311 to adjust the overall length of the tube component 31. During the extension and retraction process, the position of the second tube 312 may be fixed by friction, a latch, or a locking mechanism (the specific mechanism depends on the embodiment).

[0091] After adjusting to the required length, install one leg of the tripod onto the clamping member 32 at the end of the second tube 312 away from the first tube 311. The clamping member 32 secures the leg by clamping action (such as bolt fixing or spring clamping).

[0092] If the support span or height needs to be changed during tripod use, the second tube 312 can be extended or retracted again, the position of the clamping component 32 can be adjusted, and the legs can be re-fixed to adapt to different usage conditions.

[0093] Please continue to refer to Figure 1 , Figure 4 and Figure 5 In some embodiments, the clamping member 32 proposed in this application includes:

[0094] The third clamping member 321 is provided on the second pipe fitting 312 and has a third clamping opening 3210;

[0095] The second mounting base 322 is slidably sleeved on the second pipe fitting 312;

[0096] The second locking member 323 includes a second rod portion 3231 and a second handle portion 3232 connected to one end of the second rod portion 3231. The second handle portion 3232 is located on the side of the second mounting base 322 facing away from the third clamping member 321. The middle part of the second rod portion 3231 is threaded to the second mounting base 322.

[0097] The fourth clamping member 324 has a fourth clamping opening 3240. The fourth clamping member 324 is connected to the other end of the second rod portion 3231, and the second clamping opening 220 is disposed opposite to the first clamping opening 210.

[0098] The first locking element 325 is used to configure the second mounting base 322 and the second pipe fitting 312 to be in a relatively sliding state or to be in a relatively fixed state.

[0099] The second handle 3232 is used to drive the second lever 3231 to move, thereby causing the fourth clamping member 324 to move toward or away from the third clamping member 321, so that the third clamping jaw 3210 and the fourth clamping jaw 3240 move toward or away from each other.

[0100] In this embodiment, the working principle of the clamping member 32 is based on the synergistic mechanism of threaded transmission and sliding adjustment. The third clamping member 321 is fixed to the second pipe 312 and has a third clamping opening 3210; the fourth clamping member 324 is moved by the drive of the second locking member 323 and has a fourth clamping opening 3240, with the third clamping opening 3210 and the fourth clamping opening 3240 being arranged opposite to each other. The second mounting base 322 is slidably sleeved on the second pipe 312 and is relatively fixed or slidable with the second pipe 312 by the first locking member 325. The second locking member 323 consists of a second rod portion 3231 and a second handle portion 3232, with the middle of the second rod portion 3231 threadedly connected to the second mounting base 322 and one end connected to the fourth clamping member 324. When the second handle 3232 is rotated, the second rod 3231 moves along the thread axis, causing the fourth clamping member 324 to move closer to or away from the third clamping member 321, thereby causing the third clamping jaw 3210 and the fourth clamping jaw 3240 to clamp towards each other or release the support leg away from each other. This design combines precise control of the thread with the opposing clamping force of the jaws to ensure the fixation of the support leg.

[0101] In the initial state, the second mounting base 322 is fitted onto the second pipe fitting 312 and is in a slidable state via the first locking element 325 (which may be a bolt, pin, or clip, etc.). The user can slide the second mounting base 322 to a suitable position. The third clamp 3210 and the fourth clamp 3240 are in a loose state with a large enough gap to accommodate the support leg.

[0102] According to the installation requirements of the support leg, after sliding the second mounting base 322 to a suitable position on the second pipe fitting 312, operate the first locking member 325 (such as tightening the bolt or inserting the pin) to fix the second mounting base 322 and the second pipe fitting 312 to prevent them from sliding.

[0103] Place one of the tripod legs between the third clamp 3210 and the fourth clamp 3240, ensuring that the leg is aligned with the clamp.

[0104] The user rotates the second handle 3232 (e.g., clockwise), and the second rod 3231 moves forward along the thread in the second mounting base 322, causing the fourth clamping member 324 connected to the other end of the second rod 3231 to move closer to the third clamping member 321. The third clamping jaw 3210 and the fourth clamping jaw 3240 move towards each other, clamping the support leg.

[0105] To release the outrigger, rotate the second handle 3232 in the opposite direction (e.g., counterclockwise). The second lever 3231 will move backward, causing the fourth clamp 324 to move away from the third clamp 321. The third clamp 3210 and the fourth clamp 3240 will move in opposite directions, releasing the outrigger.

[0106] Please refer to Figure 1 In some embodiments, the tripod support device proposed in this application further includes:

[0107] A rotating shaft 4 is located on the mounting body 1, and the first pipe fitting 311 is rotatably connected to the mounting body 1 via the rotating shaft 4.

[0108] In this embodiment, the pivot 4 serves as a pivot point, fixed to the mounting body 1, and allows the first tube 311 to rotate around the pivot 4. This enables the adjustment of the angle of the first tube 311 (and its connected second tube 312 and clamping member 32) relative to the mounting body 1, making the support direction and angle of the second mounting structure 3 variable, thereby changing the spatial position of the legs. The pivot 4 is typically accompanied by a certain friction or locking mechanism, such as using a damped pivot, to ensure that the first tube 311 remains stable after rotating to the desired angle. Through this rotating connection, the pivot 4 gives the tripod support device greater flexibility and dynamic adaptability.

[0109] As a preferred embodiment of the above embodiments, please refer to Figure 4 In some embodiments, the first pipe fitting 311 proposed in this application embodiment has a threaded hole 3110, the mounting body 1 has an arc-shaped hole 104, and the tripod support device further includes:

[0110] The third locking member 7 includes a third handle portion 71 and a third rod portion 72 that are connected to each other. The third rod portion 72 passes through the arc-shaped hole 104 to be threadedly connected to the threaded hole 3110.

[0111] The third handle 71 can abut against the mounting body 1 to configure the mounting body 1 and the first pipe fitting 311 in a relatively fixed state, or the third handle 71 can not abut against the mounting body 1, and the mounting body 1 and the first pipe fitting 311 are in a relatively movable state.

[0112] In this embodiment, the working principle is based on the combination of the rotational freedom of the rotating shaft 4 and the threaded locking mechanism in the aforementioned embodiment, so as to realize the angle adjustment and fixation of the first pipe 311 relative to the mounting body 1:

[0113] Rotation adjustment: The rotating shaft 4 allows the first tube 311 to rotate around its axis, while the arc-shaped hole 104 on the mounting body 1 provides a movement path for the third rod 72, allowing the first tube 311 to rotate freely within a certain angle range. The curvature of the arc-shaped hole 104 defines the maximum range of rotation.

[0114] Threaded locking: The threaded hole 3110 on the first pipe fitting 311 is threadedly connected to the third rod portion 72 of the third locking member 7. The third handle portion 71 drives the third rod portion 72 to move forward or backward along the threaded hole 3110 by rotation. When the third handle portion 71 presses against the mounting body 1, the resulting clamping force fixes the first pipe fitting 311 to the mounting body 1, preventing it from rotating; when the third handle portion 71 is released, the first pipe fitting 311 regains its freedom of rotation.

[0115] By pressing or releasing the third handle 71, the first pipe fitting 311 and the mounting body 1 can switch between a "relatively fixed state" and a "relatively active state".

[0116] In the initial state (relatively active state), the first pipe 311 is connected to the mounting body 1 via the pivot 4, and the third rod 72 passes through the arc-shaped hole 104 and is threadedly connected to the threaded hole 3110, but the third handle 71 is not pressed against the mounting body 1. At this time, the third rod 72 can slide along the arc-shaped path within the arc-shaped hole 104, and the first pipe 311 can rotate freely around the pivot 4.

[0117] The user applies external force to push or pull the first tube 311, causing it to rotate around the pivot 4. The third rod 72 moves within the arc-shaped hole 104 as the first tube 311 rotates, adjusting the angle between the first tube 311 and the mounting body 1 to adapt to the tripod's support requirements (such as changing the leg angle to adapt to uneven ground).

[0118] After adjusting to the desired angle, the user rotates the third handle 71 (e.g., clockwise) to allow the third rod 72 to rotate deeper into the threaded hole 3110 until the third handle 71 presses against the outer surface of the mounting body 1. At this point, the third handle 71 and the first tube 311 apply clamping force to the mounting body 1 respectively, and fix the first tube 311 to the mounting body 1 through friction and thread self-locking, preventing it from rotating further.

[0119] If the angle needs to be readjusted, the user rotates the third handle 71 in the opposite direction (e.g., counterclockwise) so that the third rod 72 retracts along the threaded hole 3110, and the third handle 71 no longer abuts against the mounting body 1. The clamping force is released, and the first pipe 311 regains its freedom of rotation around the pivot 4, allowing the angle to be readjusted again.

[0120] Please refer to Figure 5 In some embodiments, the first pipe 311 of this utility model has a through hole for allowing a portion of the second pipe 312 to be exposed outside the first pipe 311. The tripod support device also includes:

[0121] Pipe clamp 5 is fitted onto the first pipe fitting 311;

[0122] The second locking member 6 is rotatably disposed on the pipe clamp 5. The second locking member 6 has an abutting part for external force to drive the second locking member 6 to rotate relative to the pipe clamp 5 so that the abutting part passes through the through hole to abut against the second pipe 312 or move away from the second pipe 312.

[0123] In this embodiment, the second tube 312 is retractably disposed inside the first tube 311. The through hole on the first tube 311 exposes part of the second tube 312, providing a contact point for locking. The through hole serves as the intervention channel for the second locking member 6, allowing an external mechanism to act directly on the second tube 312.

[0124] The pipe clamp 5 is fitted over the first pipe fitting 311, serving to fix and support it. The second locking member 6 is rotatably mounted on the pipe clamp 5, and its abutting part passes through the through hole by rotation, contacting and applying pressure to the second pipe fitting 312. When the abutting part is pressed against the second pipe fitting 312, friction or mechanical interlocking prevents the second pipe fitting 312 from sliding relative to the first pipe fitting 311, thus achieving fixation; when the abutting part moves away from the second pipe fitting 312, the second pipe fitting 312 regains its freedom of expansion and contraction.

[0125] The second locking member 6 changes the position of the abutment part by being driven by external force (such as manual rotation), and amplifies the clamping force applied to the second pipe 312 by using the lever principle, thereby achieving the locking effect.
