[0026] The photographic stand shown in Figures 1, 2, and 3 includes a support leg assembly and a pan / tilt head assembly 300 connected to the support leg assembly. The pan / tilt head assembly 300 is used to mount photographic equipment such as a camera on it, and the support leg assembly is used to provide support to the pan / tilt head assembly 300.

[0027] As shown in Figures 1, 2, and 3, in some embodiments, the camera stand is a tripod, and the support leg assembly includes a first support leg 100 and a pair of second support legs 200, the first support leg 100 and the pair of second support legs 200 having an extended state where they are extended outward, and a closed state where they are closed together and can be gripped. It should be noted that the camera stand described here is a small tripod that can be used both handheld and on a tabletop. When the first support leg 100 and the pair of second support legs 200 are in the closed state, the first support leg 100 and the pair of second support legs 200 can be gripped by hand for shooting. It is also possible to fix the support leg assembly in the closed state to another member for shooting. When the first support leg 100 and the pair of second support legs 200 are in the extended state, the first support leg 100 and the pair of second support legs 200 can be supported on a tabletop for shooting. In other alternative embodiments, the shooting stand may be a monopod having only a first support leg 100, or a multi-legged stand having three or more second support legs 200.

[0028] As shown in Figures 1, 2, and 3, in some embodiments, a pair of second support legs 200 are identical in structure and size, and the outer diameter of the second support legs 200 is smaller than the outer diameter of the first support legs 100. This is because a support leg assembly that can be used handheld cannot have an excessively large outer diameter when the legs are closed, as doing so would make it difficult to grip by hand. In this application, the outer diameter of the first support legs 100 in the support leg assembly is designed to be relatively large, and the outer diameter of the pair of second support legs 200 is designed to be relatively small. When the overall outer diameter of the support leg assembly is limited, there is sufficient mounting space inside the first support legs 100 for attaching the clamping assembly 400. The clamping assembly 400 can be stably clamped and fixed to any external object, thereby achieving positional fixation of the shooting stand and enabling the shooting stand to be stably fixed and used in any scene, solving the technical problem that conventional tripods can only be used in scenes with a horizontal ground or tabletop, thus limiting their usage scenes. Furthermore, the clamping assembly 400 can also be used to secure various photographic support devices such as mobile phones, power supplies / mobile batteries, and lighting equipment, and when used in conjunction with photographic equipment attached to the tripod head assembly 300, it improves the user experience. For example, when a mobile phone is attached to the clamping assembly 400 attached to the first support leg 100, the mobile phone and the photographic equipment on the tripod head assembly 300 can achieve double-lens shooting on a single shooting stand, and the mobile phone's lighting function can be used to provide illumination to the photographic equipment on the shooting stand even at night. When a power supply, mobile battery, or lighting equipment is attached to the clamping assembly 400 attached to the first support leg 100, the power supply or mobile battery can supply power to the photographic equipment on the shooting stand, improving the range of the photographic equipment, and the lighting equipment can provide illumination to the photographic equipment on the shooting stand, eliminating the need to set up an extra stand to provide a mounting position for the power supply, mobile battery, or lighting equipment during shooting.

[0029] As shown in Figures 1, 2, 3, and 4, in some embodiments, a fixing member 500 is fixedly connected to one end of the first support leg 100, and the first support leg 100 and the fixing member 500 may be an integrated structure or a separate assembly structure. The same end of a pair of second support legs 200 is hinged to the same rotating member 600, and the rotating member 600 maintains relative axial fixing and relative circumferential rotational positioning with respect to the fixing member 500. The relative rotation of the rotating member 600 and the fixing member 500 enables the deployment and retraction of the support leg assembly. In other embodiments, the first support leg 100 and the pair of second support legs 200 are both hinged to the outer circumference of the same mounting plate, and the first support leg 100 and the pair of second support legs 200 may deploy or close in conjunction and synchronously, or they may deploy or close independently.

[0030] As shown in Figures 1, 2, 3, and 4, in some embodiments, the pan / tilt head assembly 300 is sandwiched between a rotating member 600 and a fixed member 500, and the pan / tilt head assembly 300 is rotatably mounted around an axis parallel to the direction of connection between the rotating member 600 and the fixed member 500. A pan / tilt head lock assembly 900 is further connected between the pan / tilt head assembly 300, the fixed member 500, and the rotating member 600, and the pan / tilt head lock assembly 900 is used to lock the pan / tilt head assembly 300 between the rotating member 600 and the fixed member 500. When the pan / tilt head lock assembly 900 is controlled to release the lock, the pan / tilt head assembly 300 can rotate around the axis where the direction of connection between the rotating member 600 and the fixed member 500 is located, thereby enabling adjustment of the mounting orientation of the photographic equipment on the pan / tilt head assembly 300 and providing greater flexibility. As can be seen from this, in other embodiments, the pan / tilt head assembly 300 can be fixed to either the fixed member 500 or the rotating member 600.

[0031] As shown in Figures 1, 5, 6, and 7, the rotating member 600 includes a turntable 610 having a circular outer shell and a connecting head 620 connected to the turntable 610. The turntable 610 and the connecting head 620 may be an integrated structure or separate assembled structures. One end of a pair of second support legs 200 is connected to the connecting head 620 via a support leg rotation shaft 220, and the pair of support leg rotation shafts 220 are arranged at an angle. The support leg rotation shafts 220 are fixedly connected to the connecting head 620, and the second support legs 200 are rotatable about the axial direction of the support leg rotation shafts 220. One end of the pair of second support legs 200 is connected via a pair of oblique tooth structures 230, which facilitates the synchronous opening and closing of the pair of second support legs 200 during rotation. In this way, the pair of second support legs 200 can be easily operated to rotate at the same angle, ensuring that the pair of second support legs 200 and the mat portion of the first support legs 100 of the support leg assembly are always positioned on the same water surface after deployment, and that the support leg assembly maintains stable support after deployment. In an alternative embodiment, each of the pair of second support legs 200 can be operated to rotate independently.

[0032] As shown in Figures 6, 7, and 8, in some embodiments, the connecting head 620 has a pair of first inclined surfaces on both sides, each of which is provided with a screw hole and an arc-shaped cavity surrounding the screw hole, and the pair of arc-shaped cavities communicate with each other. As shown in Figures 5, 6, and 7, the second support leg 200 includes a support leg body 210 with a second inclined surface at its end and an oblique tooth structure 230 integrally connected to the second inclined surface of the support leg body 210. The second inclined surface of the support leg body 210 engages obliquely with the first inclined surface of the connecting head 620. The oblique tooth structure 230 is arc-shaped, centered on the axial direction of the support leg rotation axis 220, and enters into one of the arc-shaped cavities of the connecting head 620. A pair of angled tooth structures 230 of a pair of second support legs 200 are meshed and transmitted within a connecting head 620, so that when one second support leg 200 is rotated, the other second support leg 200 rotates synchronously, thereby achieving synchronous opening and closing of the pair of second support legs 200.

[0033] As shown in Figures 5, 6, and 7, the support leg body 210 is provided with a connecting through-hole that penetrates perpendicularly through the second inclined surface. The support leg rotation shaft 220 is specifically a screw, which is drilled in the connecting through-hole of the second support leg 200, and one end of the screw is screw-connected to the screw hole of the connecting head 620. The second support leg 200 is rotatably connected to the support leg rotation shaft 220 with damping. Specifically, a gasket located on the outer circumference of the screw is provided in the gap between the second support leg 200 and the connecting head 620, and a gasket located on the outer circumference of the screw is also provided in the gap between the second support leg 200 and the nut of the screw, so that when the second support leg 200 rotates, a frictional engagement is formed between the second support leg 200 and the gasket, providing rotational damping when the second support leg 200 is rotated, and making it easy to stably maintain the current state after the second support leg 200 has rotated to any angle.

[0034] As shown in Figures 1 and 8 to 11, in some embodiments, the fixing member 500 is integrally connected to one end of the first support leg 100. The fixing member 500 includes a fixed plate 510 having a circular outer shell and a central axis 520 located at the central axis position of the fixed plate 510, and the fixed plate 510 and the rotating plate 610 are disc-shaped structures provided coaxially and having the same outer diameter. An axial locking member 810 is connected between the rotating plate 610 and the central axis 520 to achieve axial position fixing and circumferential relative motion of both.

[0035] As shown in Figures 1 and 8 to 11, in some embodiments, the pan / tilt head assembly 300 includes a mounting platform 310 for mounting a photographic instrument, the mounting platform 310 is provided with screw connection ends 330, and the photographic instrument is screw-connected to the screw connection ends 330 to fix the position of the photographic instrument on the pan / tilt head assembly 300. The pan / tilt head assembly 300 further includes a pan / tilt head connecting plate 320 fixedly connected to the mounting platform 310, the pan / tilt head connecting plate 320, a fixed plate 510 and a rotating plate 610 are three discs that are coaxially arranged and have the same outer diameter, the pan / tilt head connecting plate 320 is sandwiched between the fixed plate 510 and the rotating plate 610, and an axial locking member 810 is fixedly connected to the central axis 520 on the fixed plate 510 after passing through the internal holes of the rotating plate 610 and the pan / tilt head connecting plate 320. In some embodiments, the pan / tilt head connecting plate 320 can rotate around the axial direction of the central axis 520, and the pan / tilt head lock assembly 900 is connected between the rotating plate 610 and the fixed plate 510, and the pan / tilt head lock assembly 900 is used to lock or unlock the pan / tilt head connecting plate 320.

[0036] As shown in Figures 8 to 11, a first toothed wheel 321 is provided on the side of the tripod head connecting plate 320 facing the fixed plate 510. The tripod head lock assembly 900 includes a tripod head lock sleeve 910, a pressure cover 920, and a thrust spring 930. Here, the tripod head lock sleeve 910 includes a sleeve body 911 and a disc 912, which are integral structures. The sleeve body 911 is fitted onto the outer circumference of the central axis 520 and can slide along the axial direction of the central axis 520 and can also rotate along the circumferential direction of the central axis 520. The disc 912 is fixedly connected to the outer circumference of the sleeve body 911 and has a disc-shaped structure with an outer diameter larger than that of the sleeve body 911. Both the tripod head connecting plate 320 and the rotating plate 610 are provided with through holes through which the sleeve body portion 911 is inserted. The disc portion 912 is located on the side of the tripod head connecting plate 320 facing the fixed plate 510, and a second toothed wheel 913 that meshes with the first toothed wheel 321 is provided on the side of the disc portion 912 facing the tripod head connecting plate 320. A pair of screw connection holes are provided at one end of the sleeve body portion 911 facing the rotating plate 610, and the pressure cover 920 is fixedly connected to the end of the sleeve body portion 911 closer to the rotating plate 610 via a pair of locking screws 940, and the pressure cover 920 can move within the annular cavity inside the fixed plate 510. The thrust spring 930 is elastically provided between the disc portion 912 of the tripod head lock sleeve 910 and the fixing plate 510, and the elastic force of the thrust spring 930 drives the engagement of the first tooth wheel 321 and the second tooth wheel 913 to lock the tripod head connecting plate 320.

[0037] As shown in Figures 8 to 11, when it is necessary to adjust the angular position of the tripod head assembly 300, the pressing cover 920 is pressed down, and as the pressing cover 920 is pushed down, the tripod head lock sleeve 910 is driven to overcome the elastic force of the thrust spring 930 and move toward the fixed plate 510, separating the second tooth wheel 913 on the disc portion 912 of the tripod head lock sleeve 910 and the first tooth wheel 321 on the tripod head connecting plate 320. At this time, the tripod head connecting plate 320 can be rotated around the circumferential direction of the central axis 520, thereby achieving angle adjustment of the tripod head assembly 300. After the angle of the tripod head assembly 300 is adjusted to the predetermined position, the pressure cover 920 is loosened, and the elastic force of the thrust spring 930 drives the tripod head lock sleeve 910 to reset. The second tooth wheel 913 on the disc portion 912 of the tripod head lock sleeve 910 engages with the first tooth wheel 321 on the tripod head connecting plate 320, thereby locking the tripod head connecting plate 320 and the tripod head assembly 300. The installation of the tripod head lock assembly 900 makes it easy to adjust and lock the angle of the tripod head assembly 300, and when adjusting, it is easy to operate as only the pressure cover 920 needs to be pressed down.

[0038] As shown in Figures 8 to 11, in some embodiments, damping gaskets are provided in the gap between the tripod head connecting plate 320 and the fixed plate 510, and in the gap between the tripod head connecting plate 320 and the rotating plate 610. When the tripod head connecting plate 320 rotates, frictional damping occurs between the tripod head connecting plate 320 and the damping gasket, making it easier to accurately adjust the rotation angle of the tripod head connecting plate 320 and maintaining the tripod head connecting plate 320 and the mounting platform 310 in their current angle state.

[0039] As shown in Figures 1, 12, and 13, a plurality of stepped grooves 611 are provided on the outer circumference of the turntable 610, and a step adjustment assembly 700 is provided on the first support leg 100. The step adjustment assembly 700 includes a stopper adjustment block 710 that can enter into or exit the stepped grooves 611. By having the stopper adjustment block 710 enter into different stepped grooves 611, the turntable 610 is rotated at different angles relative to the stationary platen 510 and then locked in its current position. In other words, a pair of second support legs 200 are rotated at a certain angle relative to the first support legs 100 and then locked in their current position. In this way, it is possible to lock the support leg assembly in multiple different orientations.

[0040] As shown in Figures 1, 12, and 13, in some embodiments, there are specifically three stepped grooves 611, which are the first stepped groove 611, the second stepped groove 611, and the third stepped groove 611, respectively, with an angle of 50 degrees between the second stepped groove 611 and the first stepped groove 611, and an angle of 90 degrees between the third stepped groove 611 and the first stepped groove 611. When the stopper adjustment block 710 enters the first stepped groove 611, the pair of second support legs 200 and first support legs 100 are locked in the closed position, that is, in Figure 1, the pair of second support legs 200 and first support legs 100. When the stopper adjustment block 710 enters the second stepped groove 611, the connecting head 620 and the first support leg 100, which are connected to a pair of second support legs 200, are locked in a 50-degree extended state, that is, in Figures 2 and 3, in the state of a pair of second support legs 200 and first support legs 100. When the stopper adjustment block 710 enters the third stepped groove 611, the connecting head 620 and the first support leg 100, which are connected to a pair of second support legs 200, are locked in a 90-degree extended state, that is, in Figure 4, in the state of a pair of second support legs 200 and first support legs 100.

[0041] As shown in Figures 1, 13, 15, and 16, in some embodiments, the step adjustment assembly 700 further includes an elastic member 720 and a toggle member 730, the elastic member 720 being elastically provided between the stopper adjustment block 710 and the first support leg 100, the elastic force of the elastic member 720 causing the stopper adjustment block 710 to enter the step groove 611, the toggle member 730 being fixedly connected to the stopper adjustment block 710 and exposed to the first support leg 100. When operating, the toggle member 730 is manually pushed, and the toggle member 730 drives the stopper adjustment block 710 to overcome the elastic force of the elastic member 720, moving the stopper adjustment block 710 out of the step groove 611 and releasing the lock on the circumferential position of the turntable 610, the toggle member 730 is loosened, and the stopper adjustment block 710 is reset by the action of the elastic force of the elastic member 720, achieving the circumferential position on the turntable 610 again.

[0042] As shown in Figures 2 to 4 and Figures 13 to 20, a storage groove 101 with an opening on one side is provided inside the first support leg 100, and the longitudinal direction of the storage groove 101 is the same as the longitudinal direction of the first support leg 100. When the first support leg 100 and the pair of second support legs 200 are in the closed position, the pair of second support legs 200 stop at the lateral opening position of the storage groove 101. When the first support leg 100 and the pair of second support legs 200 are in the extended position, the lateral opening of the storage groove 101 is fully open.

[0043] As shown in Figures 2 to 4 and Figures 13 to 20, a clamping assembly 400 is connected to the first support leg 100, and the clamping assembly 400 includes a first clamping arm 410, a second clamping arm 420, a sliding member 430, a first rotation shaft 440, and a second rotation shaft 450. Here, the sliding member 430 is slidably connected to the storage groove 101 along its longitudinal direction. The first rotation shaft 440 is connected to one end of the first support leg 100 near the fixing member 500, and one end of the first clamping arm 410 is rotatably connected to the first rotation shaft 440 about its axial direction. The second rotation shaft 450 is connected to the sliding member 430, and one end of the second clamping arm 420 is rotatably connected to the second rotation shaft 450 about its axial direction. The first clamping arm 410 and the second clamping arm 420 have a folded state in which they are stored in the first support leg 100 during the rotation process, and an extended state in which they are extended outward relative to the first support leg 100.

[0044] When the first clamping arm 410 and the second clamping arm 420 are folded, at least a portion of the first clamping arm 410 and at least a portion of the second clamping arm 420 are stored in the storage groove 101, allowing full use of the internal space of the first support leg 100, which is advantageous for miniaturization and compact design of the entire support leg assembly. When the first clamping arm 410 and the second clamping arm 420 are in the deployed state, they are perpendicular or nearly perpendicular to the longitudinal direction of the first support leg 100, forming a clamping space on one side of the first support leg 100, and providing the clamping assembly 400 with a clamping and fixing function. The first support leg 100 and the entire shooting stand can be fixed to any external object using the clamping assembly 400, and in this state, the sliding member 430 slides along the longitudinal direction of the storage groove 101, allowing the distance between the first clamping arm 410 and the second clamping arm 420 to be adjusted, accommodating the clamping requirements of external objects of different sizes. Furthermore, when the support leg assembly is supported on a horizontal surface or table after being deployed, the clamping assembly 400 can be used to clamp various shooting equipment or shooting aids such as mobile phones, power supplies, mobile batteries, and lighting equipment.

[0045] As shown in Figures 13 to 20, in some embodiments, a first elastic pad is provided on the inside of the first clamping arm 410, and a second elastic pad is provided on the inside of the second clamping arm 420. When the first clamping arm 410 and the second clamping arm 420 form a clamping space on one side of the first support leg 100, the first elastic pad is located on the side of the first clamping arm 410 facing the clamping space, and the second elastic pad is located on the side of the second clamping arm 420 facing the clamping space. The first and second elastic pads can provide a certain amount of cushioning, making it easier to better clamp an object located in the clamping space.

[0046] As shown in Figures 13 to 20, an adjustment assembly for further adjusting the movement position of the sliding member 430 is connected to the first support leg 100. When the first clamping arm 410 and the second clamping arm 420 are folded, it is necessary to bring the first clamping arm 410 and the second clamping arm 420 into contact with each other to restrict their rotational extension. When the first clamping arm 410 and the second clamping arm 420 are extended, it is necessary to adjust the position of the sliding member 430 and the second clamping arm 420 and hold them in the adjusted position, thereby adjusting the distance between the first clamping arm 410 and the second clamping arm 420 and ensuring that the first clamping arm 410 and the second clamping arm 420 clamp the object located within the clamping space.

[0047] As shown in Figures 13 to 20, the adjustment assembly includes an adjustment screw 460 and an adjustment knob 470. Both ends of the adjustment screw 460 are connected to the first support leg 100, and the adjustment screw 460 is rotatable about its own axial direction, with the axial direction of the adjustment screw 460 being the same as the longitudinal direction of the first support leg 100. The sliding member 430 is screw-connected to the portion of the adjustment screw 460 located within the storage groove 101. The adjustment knob 470 is fixedly connected to one end of the adjustment screw 460 that protrudes outside the storage groove 101, and the adjustment knob 470 abuts against the other end of the first support leg 100 that is away from the fixing member 500. Rotating the adjustment knob 470 drives the adjustment screw 460 to rotate about its own axial direction, causing the sliding member 430 to slide within the storage groove 101 along the axial direction of the adjustment screw 460, thereby enabling adjustment of the position of the sliding member 430 and the second clamping arm 420. The first clamping arm 410 and the second clamping arm 420 achieve the purposes of loosening control and position adjustment by rotating the adjustment knob 470, making it easy to clamp objects of different sizes. At the same time, since the sliding member 430 and the adjustment screw 460 employ a screw connection engagement method, the clamping assembly 400 is given a relatively large clamping force, and the second clamping arm 420 is less likely to loosen when subjected to external thrust, ensuring secure fixing of the shooting stand.

[0048] As shown in Figures 13 to 20, in some embodiments, sliding guide grooves 102 are provided recessed in the side walls of a pair of grooves in the storage groove 101, the cross-section of the sliding guide grooves 102 is tapered, and the longitudinal direction of the sliding guide grooves 102 is the same as the longitudinal direction of the storage groove 101. Sliding bumps 431 are provided on both opposing sides of the sliding member 430, the cross-section of the sliding bumps 431 is tapered, the same as the outer shape of the sliding guide grooves 102, and the sliding bumps 431 are slidably connected to the sliding guide grooves 102 along the guiding direction of the sliding guide grooves 102. The installation of the sliding guide grooves 102 and sliding bumps 431 ensures that the sliding member 430 does not swing from side to side when sliding, resulting in higher motion stability.

[0049] As shown in Figures 13 to 20, a hook rotation shaft 490 is provided on the adjustment knob 470, a hook 480 is connected to the hook rotation shaft 490, and one end of the hook 480 is rotatable around the axial direction of the hook rotation shaft 490. A locking groove 432 is provided on one side of the sliding member 430, and a hook-shaped portion 481 is provided on the end of the hook 480 that is away from the hook rotation shaft 490. The hook 480 has a folded state and a hook-extended state during the rotation process around the hook rotation shaft 490. When the hook 480 is in the folded state, the hook-shaped portion 481 at the end of the hook 480 is locked into the locking groove 432 of the sliding member 430, forming a stopper engagement, preventing the adjustment knob 470 from being rotated and thus locking the adjustment knob 470. When the hook 480 is in the extended position, the hook-shaped portion 481 at the end of the hook 480 is suspended from one side of the adjustment knob 470. In this state, the suspended hook 480 can increase the rotational moment arm of the adjustment knob 470, forming an auxiliary biasing portion that makes it easier to operate the rotation of the adjustment knob 470, thus reducing the effort required to rotate the adjustment knob 470. Furthermore, the suspended hook 480 can be used as a hanging part, allowing the shooting stand to be hung on a wall or other surface, realizing a claw-type wall-mounted storage function, which is useful for temporarily setting down the shooting stand.

[0050] As shown in Figures 13 to 20, in some embodiments, rotational damping is provided between the first clamping arm 410 and the first rotating shaft 440. The first rotating shaft 440 includes a pair of short screws, which are connected between the first support leg 100 and the first clamping arm 410. A pair of first damping gaskets are fitted around the outer circumference of the short screws, and the pair of first damping gaskets are pressed against opposing sides of the first support leg 100. When the first clamping arm 410 rotates, a frictional engagement is formed between the first clamping arm 410 and the first damping gaskets, providing rotational damping when the first clamping arm 410 is rotated. Rotational damping is provided between the second clamping arm 420 and the second rotating shaft 450. In some embodiments, the second rotating shaft 450 includes a long screw connected between the sliding member 430 and the first clamping arm 410, a pair of second damping gaskets fitted around the outer circumference of the long screw, the pair of second damping gaskets pressed against the gap between the sliding member 430 and the first clamping arm 410, a frictional engagement formed between the second clamping arm 420 and the second damping gaskets when the second clamping arm 420 rotates, and rotational damping is provided when the second clamping arm 420 rotates.

[0051] As described above, the camera stand provided in this invention is further equipped with a foldable and deployable clamping assembly 400 on the first support leg 100 of the camera stand. The first clamping arm 410 and the second clamping arm 420 of the clamping assembly 400 can be deployed outward to form a clamping space on one side of the first support leg 100, thus providing the clamping assembly 400 with a clamping function. The first clamping arm 410 and the second clamping arm 420 can be deployed outward to clamp onto any external object, thereby serving to fix the camera stand in place. This camera stand can be used while stably supported on a horizontal ground by the support leg assembly, or by clamping and fixing the clamping assembly 400 on the first support leg 100 to an external object. This makes it possible to stably fix and use the camera stand in any scene, thus expanding the range of usage scenarios. Furthermore, the clamping assembly 400 can also be used to clamp various photographic equipment or photographic support equipment such as mobile phones, power supplies, mobile batteries, and lighting fixtures. This solves the technical problem that various photographic equipment or photographic support equipment cannot be fixed to a small photographic stand and used together with the photographic equipment on the pan / tilt head assembly 300. This enhances the functionality of the first support leg 100 and greatly improves the user experience without significantly increasing the size of the photographic stand.

[0052] Naturally, the above embodiments are illustrative for illustrative purposes only and do not limit the embodiments. Those skilled in the art can make other different forms of modifications or variations based on the above description. It is impossible and unnecessary to comprehensively list all embodiments here. Any obvious modifications or variations derived therefrom still fall within the scope of the present invention. [Explanation of symbols]
