Description

Technical Field

[0001] This utility model belongs to the technical field of photographic equipment, specifically relating to a multifunctional photographic tripod. Background Technology

[0002] A photography tripod is a support and stabilizing bracket used for cameras or other photographic equipment. It provides a stable platform during shooting, helping photographers obtain sharp, clear images and reducing blur caused by camera shake. The ability to quickly adjust the height for low-angle and ground-level shooting, and the ability to quickly connect to devices such as ball heads with different screw mounts, are crucial features.

[0003] For example, Chinese invention patent (authorization announcement number: CN118309901A) discloses a tripod center column that can be converted into a desktop tripod structure, including a tripod body and a center column structure. The center column structure extends through the upper and lower sides of the tripod body and is slidably connected to the tripod body. Desktop tripod legs are slidably connected inside the center column structure, and a desktop tripod connecting part is provided at the top of the desktop tripod legs. The top of a fastening screw passes through a mounting disc and extends through the center hole of the three-compartment base to the top of the mounting disc, used for mounting the pan-tilt head equipment that requires a tripod. The tripod legs are fixed by tightening the fastening screw through the fixing plate and the center hole of the three-compartment base. The fastening screw extends from the center of the three-compartment base for connecting the pan-tilt head equipment. The tripod center column proposed in this invention can be converted into a desktop tripod structure, which is convenient to carry and use. At the same time, it eliminates the need for users to waste time assembling and can be used as a desktop tripod for macro photography after being pulled out. It solves the problem that current small and medium-sized tripods cannot meet the needs of use and that users need to carry an additional macro desktop tripod, which causes inconvenience. Therefore, it has good application prospects and can be widely used in various parts and components of tripod photography equipment.

[0004] However, the aforementioned tripod with a center column structure is inconvenient for quick adjustments when shooting at low angles or close to the ground, and the fastening screws on the mounting plate can only connect to gimbals and other devices with one type of screw hole, resulting in poor compatibility with devices with different screw hole sizes. Therefore, it is necessary to design a new solution to address these issues. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0070] In one embodiment of this utility model, such as Figure 1-2 As shown, a multi-functional photographic tripod is provided, including a top mechanism 1, a rotating locking mechanism 2, and a support mechanism 3. The top mechanism 1 is used to mount photographic equipment such as a gimbal, and includes a top mount 11, a toothed rod 12, a toothed sleeve 13, a first elastic element 14, and a flange gasket 15. The support mechanism 3 is used to support the photographic equipment on the top mechanism 1 for photographic work in different locations, and includes legs 31, a telescopic locking assembly 32, a sliding sleeve 33, and foot cups 34. The rotating locking mechanism 2 is installed between the top mechanism 1 and the support mechanism 3, and is used to adjust the legs 31 to open outwards for support or to retract inwards for closure. The rotating locking mechanism 2 includes a rotating head 21, a rotating assembly 22, and a locking assembly 23.

[0071] Furthermore, such as Figures 3-7As shown. A top hole 112 is provided at the middle position of the top of the top seat 11, penetrating the bottom of the top seat 11. One end of the toothed rod 12 passes through the top hole 112 and extends out of the top of the top seat 11. The shaft section of the toothed rod 12 extending out of the top end is provided with external thread. The other end of the toothed rod 12 is provided with a toothed rod connecting section 121. The bottom of the top hole 112 is provided with a top hole connecting section 1121. The top hole connecting section 1121 and the toothed rod connecting section 121 are respectively provided with internal and external threads. The toothed rod connecting section 121 is threadedly connected to the top hole connecting section 1121.

[0072] The top of the top hole 112 of the top seat is provided with a top hole limiting section 1122, and the top hole limiting section 1122 and the top hole connecting section 1121 are provided with a top hole clearance section 1123. The tooth rod 12 is fitted with a tooth sleeve 13 and a first elastic element 14.

[0073] The dental sleeve 13 has a locking section 131 at one end. The first elastic member 14 elastically abuts against the connecting section 121 and the locking section 131 at both ends. The axial diameter of the connecting section 121 is larger than the radial outer dimension of the first elastic member 14. The portion of the dental sleeve 13 that fits onto the dental rod 12 is a hollow hole with a diameter larger than the diameter of the dental rod 12. The locking section 131 is an outwardly convex ring structure, and the top hole limiting section 1122 is an inwardly convex ring structure. The diameter of the locking section 131 is larger than the radial outer dimension of the first elastic member 14 and the diameter of the top hole limiting section 1122. The dental sleeve 13 is pushed upward by the first elastic member 14, passing through the top hole 112 and extending to the top, while the locking section 131 is locked and limited by the top hole limiting section 1122. After being pressed, the dental sleeve 13 can move downward along the axial section of the dental rod 12 in the top hole clearance section 1123. The outer periphery of the tubular structure extending from the top of the toothed sleeve 13 is provided with external threads. The toothed sleeve 13 and the toothed bar 12 extend out of the top hole 112 of the top seat at the same height.

[0074] Specifically, the first elastic element 14 is a compression spring. The thread on the tube body of the toothed sleeve 13 extending from the top hole 112 of the top seat is a 3 / 8 inch thread, and the thread on the rod body of the toothed bar 12 extending from the top hole 112 of the top seat is a 1 / 4 inch thread. Pressing down on the toothed sleeve 13 will expose the toothed bar 12, thus converting the 3 / 8 inch screw to a 1 / 4 inch screw. In actual use, depending on the specific size of the mounting screw holes of the tripod head or other photographic equipment mounted on the top seat 11, it can be connected to either the toothed sleeve 13 or the toothed bar 12. This design makes the tripod of this utility model more compatible, avoiding the inconvenience of tripods that require different specifications of mounting screws or the cumbersome operation of adding conversion screws, making it easy to carry and operate.

[0075] Furthermore, such as Figure 2 and Figure 3As shown, the top seat 11 has a flange gasket groove 114 on its top, which is in the same direction as the top hole 112 of the top seat. The flange gasket groove 114 is located around the top hole 112 of the top seat, and a flange gasket 15 is installed in the flange gasket groove 114. The flange gasket 15 is made of rubber to prevent rigid contact and scratch damage when equipment such as the gimbal is installed on it, and also plays a role in buffering and shock absorption during photography operations.

[0076] Furthermore, such as Figure 2 , Figure 3 , Figure 10 and Figure 11 As shown, three rotating heads 21 are hinged to the side of the top seat 11, and the top seat 11 and the rotating heads 21 are hinged together by a rotating assembly 22. The rotating assembly 22 includes a damping sleeve 221, a washer 222, and a connecting rod 223.

[0077] The top seat 11 has a top seat hinge hole 113. The rotating head 21 has two ears 213 at the two ends aligned with the top seat hinge hole 113. Each ear 213 has an ear hole 2131. The two ears 213 are two symmetrically arranged, arc-shaped, protruding plate structures, allowing the rotating head 21 to rotate around the ear holes 2131 at a certain angle. The damping sleeve 221 is inserted into the top seat hinge hole 113. The washer 222 is aligned and installed at both ends of the top seat hinge hole 113. The connecting rod 223 passes through the ear hole 2131 and the washer 222 and is detachably connected to the damping sleeve 221. Specifically, the washer 222 is a copper flat washer, the connecting rod 223 is a countersunk screw, the damping sleeve 221 is a sleeve structure with a threaded hole on its inner wall that matches the connecting rod 223, and the ear hole 2131 has a tapered countersunk hole at its opening. The rotating assembly 22 has a damping effect, which reduces the tripod's swaying caused by wind or other external forces, improving the stability of the photographic image. The damping sleeve 221, the pad 222, and the connecting rod 223 are also easy to replace when they wear down to a certain extent, ensuring good performance.

[0078] like Figure 8-10 As shown, the rotating head 21 has expansion holes 214 on its two outer sides where the ear hole 2131 is located. The expansion holes 214 are 1 / 4-inch screw holes, which facilitate the expansion of external mobile phones, fill lights and other devices by installing adapter structures such as magic arms to meet photography needs.

[0079] Furthermore, such as Figure 2 , Figures 8-13 and Figure 16 As shown, the locking assembly 23 includes a locking buckle 231 and a second elastic element 232, which is a compression spring. The top seat 11 has several stepped slots 111 on its outer side at the hinge point of the rotating head 21 and parallel to the axis of the top seat hinge hole 113. The locking assembly 23 is installed on the rotating head 21 with the slots 111 aligned with the slots 111.

[0080] The latch 231 has a latch blind hole 23131, and the rotating head 21 has a rotating head blind hole 211 vertically downward on the plane between the roots of the two ears 213. The two ends of the second elastic member 232 abut against the latch blind hole 23131 and the rotating head blind hole 211 respectively.

[0081] The two opposing planes on the inner side of the ear 213 are vertical planes perpendicular to the bottom of the blind hole 211 of the rotating head. The rotating head 21 has a large U-shaped blind groove 215 extending downwards from the opening of the blind hole 211. This groove has two sides that surround the outer perimeter of the opening and are parallel to the inner side of the ear 213; one side is perpendicular to the inner side of the ear 211, and the other side is through-hole. The bottom of the large U-shaped groove is located in the area above the bottom of the blind hole 211. The reverse side of the bottom of the large U-shaped blind groove 215 forms a sidewall with the groove bottom. A small U-shaped groove, similar in direction and smaller than the large U-shaped blind groove 215, is formed through this sidewall. This small U-shaped groove is the sliding groove 212. The sidewall where the sliding groove 212 is located has a wedge-shaped structure with a thin sidewall at the opening of the small U-shaped groove and a thick sidewall at the bottom of the small U-shaped groove.

[0082] The latch 231 has a pressing part 23111, an abutting part 23132, and a sliding part 23121. The pressing part 23111 is located on the top surface of the pressing block 2311. The sliding part 23121 consists of two planes on the flat block that can slide within the slide groove 212 along the axis of the blind hole 211 of the rotating head and are slidably connected to the slide groove 212. The latch blind hole 23131 is vertically formed on one surface of the cuboid block 2313. The pressing block 2311 and the cuboid block 2313 are respectively connected to the two ends of the plane where the sliding part 23121 of the flat block 2312 is located. The bottom surface of the pressing block 2311 is close to and parallel to the outer wall of the side wall where the slide groove 212 is located. The plane of the cuboid block 2313 close to the inner wall of the side wall where the slide groove 212 is located is parallel to the inner wall. The bottom surface of the pressing block 2311 can slide along the outer wall. The plane of the cuboid block 2313 close to the inner wall of the side wall can slide along the inner wall. When the latch 231 moves toward the bottom of the blind hole 211 of the rotating head, the gap between the wedge-shaped space formed by the bottom surface of the pressing block 2311 and the plane of the cuboid block 2313 close to the inner wall of the side wall and the side wall where the slide groove 212 is located becomes smaller until it contacts.

[0083] The blind hole 23131 is perpendicular to the normal of the plane of the cuboid block 2313 near the inner side wall, and the blind hole 23131 is parallel and aligned with the blind hole 211 of the rotating head. A step is provided at the opposite end of the blind hole 23131 on the cuboid block 2313. The riser of the step is parallel to the plane of the cuboid block 2313 near the inner side wall. The tread at the top of the step is at an angle, sloping downward from the boundary line between the tread and the riser towards the boundary line between the tread and the plane of the cuboid block 2313 near the inner side wall, so that the boundary between the tread and the riser at the top of the step is pointed.

[0084] The area where the riser and the inclined tread of the cuboid block 2313 step meet is the abutment part 23132. The top seat 11 has a number of slots 111 in the area where the top seat hinge hole 113 is opened, the outer side parallel to the top seat hinge hole 113, and the area from near the bottom to near the top. The abutment part 23132 can adjust the tilt angle of the outward expansion of the support leg 31 by abutting with different slots 111. When the abutment part 23132 abuts with the slot 111 near the top area of ​​the top seat 11, the tripod support leg 31 is adjusted to a negative tilt angle (one end of the support leg 31 is higher than the end of the support leg 31 connected to the rotating head). When it is necessary to adjust the support leg 31 to open outward or close inward, press the pressing part 23111 backward. The second elastic member 232 is compressed, and the sliding part 23121 slides in the sliding groove 212, so that the abutting part 23132 abuts against the appropriate slot 111. Then release the pressing part 23111, and the second elastic member 232 releases its elastic force to tighten, so that the rotating head 21 is locked with the top seat 11.

[0085] Specifically, such as Figure 1 , Figure 22 and Figure 23 As shown, by controlling the locking assembly 23, the support mechanism 3 can be adjusted to extend outward to adjust the mounting height or support angle of the photographic equipment, or to retract inward for easy storage and carrying. The locking assembly 23 can also quickly adjust the tripod's support mechanism 3 to a negative tilt angle to adapt to shooting on uneven terrain such as hillsides and rocky beaches. Tripods with a center column have the center column installed downwards in the middle of the top mount 11, which interferes with the ground. Therefore, the top mount 11 for mounting the camera cannot be placed very low. For low-angle and ground-level shooting, the center column needs to be removed or the tripod head reversed (camera head down), which is cumbersome. Furthermore, compared to tripods with a center column, this new tripod saves space for installing the center column, reduces the weight of the center column, and is smaller and lighter when folded, making it easier to store and carry.

[0086] Furthermore, such as Figure 2 , Figure 15 and Figure 19 As shown, the end of the rotating head 21 away from the top seat 11 is connected to the support leg 31, which includes a sleeve 311 and a foot tube 312. The foot tube 312 extends into one end of the sleeve 311, and the other end of the sleeve 311 is fastened to the rotating head 21. The telescopic locking assembly 32 is installed at the joint between the sleeve 311 and the foot tube 312.

[0087] like Figures 17-19 As shown, the telescopic locking assembly 32 includes a foot clamp 321, an outer clamp 322, and a locking sleeve 323.

[0088] The foot clamp 321 is located at the end of the sleeve 311. The foot clamp 321 is sleeved on the foot tube 312 and one end of the foot tube 312 passes through the foot clamp 321 and extends into the sleeve 311.

[0089] The outer surface of the foot clamp 321 near the end of the sleeve 311 is provided with a foot clamp conical surface 3211. One end of the inner wall of the outer clamp 322 is provided with an outer clamp conical hole section 3221, and the other end is provided with an outer clamp fastening section 3222. The outer clamp conical hole section 3221 and the foot clamp conical surface 3211 are connected by a conical interference fit. The outer clamp fastening section 3222 is sleeved on the end of the sleeve 311 and is fastened to the sleeve 311.

[0090] The outer hoop 322 has an outer hoop threaded surface 3223 on its outer surface. The foot hoop 321 has a foot hoop ring groove 3212 on the outer surface of the other end of the foot hoop conical surface 3211. The inner wall of the locking sleeve 323 has a locking sleeve threaded hole 3231 at one end and a locking sleeve protrusion 3232 at the other end. The locking sleeve protrusion 3232 is inserted into the foot hoop ring groove 3212, and the locking sleeve threaded hole 3231 is threadedly connected to the outer hoop threaded surface 3223.

[0091] The leg clamp 321 is made of elastic material. By screwing on the locking sleeve 323, the conical surface 3211 of the leg clamp and the conical hole section 3221 of the outer clamp are locked together through an interference fit. This locks and fixes the sleeve 311 and the leg tube 312, or loosens it to adjust the length of the leg tube 312 extending into the sleeve 311, thereby adjusting the length of the tripod leg 31. The tripod leg 31 can be shortened for storage or extended for photography, and the angle of the tripod can be adjusted. Compared with the lever, the locking sleeve 323 has a greater locking force, is less prone to loosening after repeated use, has fewer and smaller gaps, is less likely to allow sand or other foreign objects to enter, and can be quickly disassembled and assembled by hand, resulting in better performance.

[0092] Furthermore, such as Figure 17 and Figure 18 As shown, the locking sleeve 323 has a locking sleeve screwing part 3233 around its periphery. The locking sleeve screwing part 3233 has several grooves along the axial direction, which play a role in preventing slipping and enhancing the comfortable feel, making it easier and more comfortable to adjust the extension and retraction of the support leg 31.

[0093] Furthermore, such as Figure 20 and Figure 21As shown, a sliding sleeve 33 is fitted onto the end of the leg tube 312 that extends into the sleeve 311, and the sliding sleeve 33 is slidably connected to the inner wall of the sleeve 311. Two sliding sleeve protrusions 331 are symmetrically arranged on the inner side of the sliding sleeve 33, and two leg tube grooves 3121 are formed at the corresponding two sliding sleeve protrusions 331. The sliding sleeve protrusions 331 are engaged in the leg tube grooves 3121 for secure connection. The sliding sleeve 33 is made of rubber, which has good elasticity and wear resistance. The sliding sleeve 33 contacts the sleeve 311, preventing the metal leg tube 312 from directly contacting the inner wall of the sleeve 311 and damaging the contact surface during extension and retraction. The sliding sleeve 33 also serves as a guide, making extension and retraction adjustments smoother, and also has an anti-slip function when supporting the tripod.

[0094] Furthermore, such as Figure 20 and Figure 21 As shown, a foot cup 34 is fastened to the end of the leg tube 312 away from the leg tube groove 3121. The bottom of the foot cup 34 has a foot cup connection hole 341 to connect the foot spikes and rubber pads and other support components, so as to adapt to the needs of different photography scenarios for tripod support feet.

[0095] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
