[0035] With the continuous improvement of living standards, the number of photography enthusiasts is growing. Support frames such as gimbal tripods are one of the essential tools for photography enthusiasts. The gimbal tripod is used to fix the shooting equipment to avoid the user's hand or arm discomfort caused by holding the shooting equipment for a long time, and to ensure the stability of the shooting equipment during shooting, so as to obtain good shooting effects. In photography, a tripod is usually used to support the camera, and the center axis is used to install the camera. In order to facilitate daily carrying, each leg needs to be folded inward when not in use. Combined with reference Figure 1 and Figure 2 The present application provides a tripod 10 that is easy to unfold and store. The tripod 10 includes a base 100, a central axis 200, and a tripod body 300. The base 100 serves as a connection or mounting structure. The central axis 200 is connected to the base 100. The tripod body 300 is connected to the base 100 and is arranged around the central axis 200. The tripod body 300 can be unfolded and folded so that the tripod 10 can be switched between an unfolded state and a stored state. Specifically, the tripod body 300 includes three legs 310. The three legs 310 are arranged around the central axis 200 along the circumference of the central axis 200. Each leg 310 has a rotating end 311 and a supporting end 312 located in the direction of its length extension. The rotating end 311 is rotatably connected to the base 100. The supporting ends 312 can approach and move away from each other so that the tripod body 300 can be switched between an unfolded state and a folded state. Figure 1 As shown, when the tripod 10 is in the storage state, the three support ends 312 are close to each other, and the central axis 200 and the three legs 310 are folded side by side to present a single handheld support pole; Figure 2 As shown, when the tripod 10 is in the unfolded state, the three support ends 312 are away from each other, that is, the three legs 310 are spread out around the central axis 200 to present a tripod support state and supported on a support surface.

[0036] Preferably, the central axis 200 of this embodiment is connected to the base 100 along the thickness direction of the base 100 and is used to install the shooting equipment. Figure 3 and Figure 4 The middle axis 200 is a telescopic rod and can be extended and shortened on the side away from the tripod body 300. Figure 3 As shown, the tripod body 300 is in a folded state and presents a single handheld support rod, and the rod portion of the central axis 200 away from the tripod body 300 is extended, so that the tripod 10 becomes a selfie stick with variable length; Figure 4As shown, when the tripod body 300 is in the unfolded state, the rod part of the central axis 200 away from the tripod body 300 is extended, and the tripod 10 becomes a monopod with adjustable height. Therefore, the tripod 10 of this embodiment realizes the multifunctionality of photography support, and the user can switch the tripod 10 between a tripod, a selfie stick, and a monopod at will to adapt to different shooting scenes, thereby greatly improving the practicality of the tripod 10. It should be understood that in other embodiments, firstly, the shooting equipment can also be installed on the base 100, and the central axis 200 only serves to increase the central fixing function of the support stability; secondly, the central axis 200 is not necessarily retractable, which is not limited in this application.

[0037] Preferably, reference Figure 1 The inner and outer walls of the three legs 310 are arc surfaces. When the tripod body 300 is in the folded state (when the tripod 10 is in the storage state), the three legs 310 are close to each other and combined to form a hollow cylinder. The central axis 200 is surrounded and sleeved in the middle of the three legs 310 and the tripod body 300. This design makes the tripod 10 as close to each other as possible without gaps, and the storage is more compact and stable. Figure 5 , there are multiple sets of position-limiting engaging structures between the side walls of adjacent legs 310, including a block 313 and a slot 314, which are respectively arranged on the two side walls of two adjacent legs 310 that are in contact with each other. When the tripod body 300 is in the folded state, the block 313 is aligned and engaged with the slot 314 to further enhance the stability of the tripod body 300 in the folded state. It should be understood that, firstly, the shape of the legs 310 is not limited, and it is only necessary to satisfy that the three legs 310 are arranged circumferentially around the central axis 200; secondly, under the premise of not considering the further stability of the storage, in other embodiments of the present application, the side walls of the legs 310 do not need to be provided with a block 313 or a slot 314.

[0038] refer to Figure 5The tripod 10 of the present application further includes auxiliary rods 400, which are three in number and are arranged between the central axis 200 and the tripod body 300, thus greatly improving the stability of the tripod 10 after being opened. Specifically, for the sake of clear description, the end of the central axis 200 away from the base 100 is defined as the central axis bottom end 210 (when the tripod 10 is stored, the central axis bottom end 210 is close to the support end 312 of the leg 310), one end of each auxiliary rod 400 is hinged to the central axis bottom end 210, and the other end of the auxiliary rod 400 is hinged to the inner side wall of the leg 310. Optimally, the inner wall of the leg 310 is provided with a storage groove 315 corresponding to the auxiliary support rod 400. As the tripod body 300 switches from the unfolded state to the folded state, the auxiliary support rod 400 is also rotated and limitedly stored in the storage groove 315, so that the tripod body 300 is more compact and stable in the folded state. It should be understood that, firstly, without considering the stability of the tripod 10 when opened, in other embodiments of the present application, the auxiliary support rod 400 may not be provided; secondly, without considering the folding stability of the tripod body 300, in other embodiments, a storage groove for limiting the storage of the auxiliary support rod 400 may also be omitted.

[0039] Combined with reference Figure 5 and Figure 6 The tripod 10 of the present application further includes a limit structure and an unlock button 600. When the tripod 10 is in the storage state, the limit structure is used to limit and maintain the storage state of the tripod 10 to prevent the tripod 10 from opening; the unlock button 600 can be pressed by a user to unlock the tripod 10, release the restriction, and switch the tripod 10 from the storage state to the open state. Specifically, refer to Figure 6 The limiting structure includes a limiting block 510, a limiting groove 520 and a reset member 530. The limiting block 510 and the limiting groove 520 are aligned and engaged with each other. The reset member 530 is arranged between the limiting block 510 and the central axis 200. The reset member 530 provides a reset force so that the limiting block 510 is aligned and engaged in the limiting groove. Figure 5 As shown, there are three limit blocks 510 and they are arranged at intervals along the circumferential direction of the central axis 200 at the bottom end 210 of the central axis. Two linked engaging blocks 511 are arranged at the end of each limit block 510. There are three limit grooves 520 (groups) and they are respectively arranged at the support ends 312 of the three legs 310. Each limit groove 520 includes two engaging grooves 521 arranged at intervals on the same leg 310. Figure 7 The two engaging grooves 521 on the same leg 310 are respectively engaged with the two engaging blocks 511 on the two adjacent limiting blocks 510 ; the two linked engaging blocks 511 on the same limiting block 510 are engaged with the two engaging grooves 521 on the two adjacent legs 310 .

[0040] Optimally, reference Figure 6The reset member 530 of the embodiment of the present application is three telescopic springs 531. The telescopic springs 531 accumulate and release elastic force along the axial direction of the middle axis 200. When the tripod body 300 is in the folded state, the limit block 510 can be pressed into the end surface of the bottom end 210 of the middle axis by the unlocking button 600 and disengage from the limit groove 520. In this process, the telescopic springs 531 are synchronously compressed and accumulate elastic force; the elastic force released by the telescopic springs 531 can push the limit block 510 out and protrude from the end surface of the bottom end 210 of the middle axis and align and engage with the limit groove 520. It should be understood that in the present application, the reset member 530 can be a telescopic spring 531 that acts on the three limit blocks 510 at the same time. The implementation method of the reset member 530 is not limited. It can be a telescopic spring 531, or it can be elastic rubber, mutually exclusive magnetic parts, etc. It is only necessary to satisfy that the reset member 530 provides a reset force to help the limit block 510 to align and engage with the limit groove 520; secondly, the direction of the reset force varies according to the setting positions of the limit block 510 and the limit groove 520.

[0041] The unlock button 600 is movably disposed at the bottom end 210 of the middle axis. When the tripod body 300 is in the folded state, the unlock button 600 is pressed, and the unlock button 600 simultaneously drives the three limit blocks 510 to move relative to the middle axis 200, and the engaging blocks 511 are all disengaged from the engaging grooves 521, and the tripod body 300 switches to the unfolded state. Specifically, in this embodiment, refer to Figure 6 The unlock button 600 includes a pressing column 610, a connecting column 620 and an end cap 630. The pressing column 610 is exposed at the bottom end 210 of the central axis for a user to press and operate. One end of the connecting column 620 is connected to the pressing column 610. The other end of the connecting column 620 passes through the bottom end 210 of the central axis along the axial direction of the central axis 200 and is engaged with the central axis 200, so that the unlock button 600 is engaged with the central axis 200 and moves back and forth along the axial direction of the central axis 200. The end cap 630 is integrally formed with the pressing column 610 and connected to the periphery of the pressing column 610. The end cap 630 covers the end surface of the bottom end 210 of the central axis. The end surface of the end cover 630 is provided with three avoidance holes 631 spaced apart along the circumferential direction, and the positions of the three avoidance holes 631 correspond to the positions of the three limit blocks 510 one by one, so that the limit blocks 510 can be movably installed in the avoidance holes 631; the edge of the end cover 630 is provided with three avoidance notches 632 spaced apart along the circumferential direction, and the three avoidance notches 632 correspond to the end positions of the auxiliary support rod 400 one by one, so that the auxiliary support rod 400 can be turned and moved in the avoidance notches 632. It should be understood that in other embodiments, the connecting column 620 may not be provided, and the unlocking button 600 may be directly engaged and embedded in the bottom end 210 of the central axis; in other embodiments, the end cover 630 may not be provided, and the end cover 630 is provided to protect the end surface of the bottom end 210 of the central axis on the one hand, and to facilitate the opening of the avoidance area (avoidance hole 631 and avoidance notch 632) on the other hand.

[0042] The tripod 10 of the embodiment of the utility model comprises a base 100, a central axis 200, a tripod body 300, a limiting structure (a limiting block 510 and a limiting slot 520) and an unlocking button 600. The tripod body 300 comprises three legs 310, which are all rotatably connected to the base 100 and can move closer to and farther from each other, so that the tripod body 300 can switch between an unfolded state and a folded state; the limiting structure comprises a limiting block 510, a limiting slot 520 and a reset member 530, and the limiting block 510 automatically aligns and engages with the limiting slot 520 under the reset force of the reset member 530, so that the tripod body 300 is stabilized in a folded state. There are three limiting blocks 510 and three limiting slots 520, each limiting block 510 comprises two linked engaging blocks 511, and each limiting slot 520 comprises two spaced engaging slots 521 located on the same leg 310. The two engaging grooves 521 on the same leg 310 are respectively engaged with the engaging blocks 511 on the two adjacent limiting blocks 510, and the two engaging blocks 511 on the same limiting block 510 are respectively engaged with the two engaging grooves 521 on the two adjacent legs 310. When the tripod body 300 is in the folded state, the unlocking button 600 can be pressed to drive the three limiting blocks 510 to move synchronously, so that all the engaging blocks 511 are simultaneously disengaged from the engaging grooves 521, and the tripod body 300 is switched to the unfolded state. In the storage state, the tripod 10 of the present application can not only be unlocked and unfolded by one-key triggering (pressing), but also because the two linked engaging blocks 511 are respectively engaged with the two adjacent legs 310, the two adjacent legs 310 are mutually restricted from shaking and moving by the two linked engaging blocks 511, thereby enhancing the compactness and stability of the tripod 10 after folding, and will not be easily unfolded, which is more conducive to the user's daily storage and carrying.

[0043] refer to Figure 5 The supporting end 312 of the supporting leg 310 has a buckle block 316 which is perpendicular to the length direction of the supporting leg 310 and extends toward the central axis. The limiting groove 520 is provided on the inner side wall of the buckle block 316, and the limiting block 510 is movably provided on the end surface of the bottom end 210 of the central axis. When the tripod body 300 is in a folded state, the buckle block 316 is hooked on the end surface of the bottom end 210 of the central axis, and the limiting block 510 is aligned and engaged with the limiting groove 520. It should be understood that in other embodiments, the buckle block 316 may not be provided, and the positions of the limiting block 510 and the limiting groove 520 are not specifically limited. It is only necessary that the limiting block 510 is provided at the bottom end 210 of the central axis, and the limiting groove 520 is provided at the supporting end 312, that is, the limiting structure is provided on the side of the tripod 10 away from the base 100. Preferably, in this embodiment, reference Figure 1When the tripod body 300 is in the folded state, the pressing column 610 is seamlessly embedded between the three buckle blocks 316, that is, the outer wall surface of the pressing column 610 is seamlessly fitted with the side wall surface of the buckle block 316. This design makes the volume of the tripod 10 after storage more compact, and there is no gap between the parts that contact each other, making the structure more compact, more stable, and more beautiful in appearance. It should be understood that, without considering the compactness of storage and appearance, in other embodiments, when the tripod body 300 is in the folded state, the pressing column 610 and the buckle block 316 do not need to be seamlessly embedded, and a gap can be left between them.

[0044] Preferably, in combination with reference question 6 and Figure 7 In this embodiment, the pressing column 610 is a triangular prism 611, and each limiting block 510 also includes a limiting surface 512. The limiting surface 512 is located between the two engaging blocks 511, that is, the two engaging blocks 511 on the same limiting block 510 are arranged at intervals, and the bottom surface of the middle gap is the limiting surface 512. The three corners of the triangular prism 611 abut against the limiting surface 512. By pressing the triangular prism 611, the three limiting blocks 510 can be driven to move synchronously. The design of the triangular prism 611 corresponds to the three limiting blocks 510. When the tripod body 300 is in a folded state, the side of the triangular prism 611 is seamlessly fitted with the side of the buckle block 316. The storage compactness and beauty of the tripod 10 are increased. It should be understood that, in other embodiments, firstly, the shape of the pressing column 610 is not limited, and it is only necessary that the three abutting parts press the three limit blocks 510 synchronously; secondly, the two locking blocks 511 of the same limit block 510 are not necessarily arranged at intervals, that is, the existence of the limiting surface 512 is not limited, and it is only necessary that the edges and corners of the triangular prism 611 abut between the two locking blocks 511 of the same limit block 510, so as to achieve synchronous control of the synchronous movement of the two locking blocks 511 on the limit block 510.
