[0029] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0030] Reference Figure 1According to the first embodiment of the utility model, the support leg comprises: two support rods 100, a mounting tube 200 and a locking assembly 300; the two support rods 100 are both movably mounted on the mounting tube 200, one of the two support rods 100 can slide into or out of the mounting tube 200 from one end of the mounting tube 200, and the other of the two support rods 100 can slide into or out of the mounting tube 200 from the other end of the mounting tube 200; the locking assembly 300 is arranged on the mounting tube 200, the locking assembly 300 can synchronously fix the two support rods 100 to the mounting tube 200, and the locking assembly 300 can synchronously release the fixing effect between the two support rods 100 and the mounting tube 200. After the support rods 100 move relative to the mounting tube 200 and extend into or out of the end of the mounting tube 200, the overall lengthening or shortening effect of the support leg can be directly and effectively achieved. The two support rods 100 are respectively moved from the two ends of the mounting tube 200, so the entire support leg can be extended and retracted at least twice at the mounting tube 200, thereby providing a larger extension range to facilitate the adjustment of the position of the photographic equipment. After the two support rods 100 are moved, the two support rods 100 can be fixed synchronously by the locking assembly 300. Therefore, the synchronous locking or unlocking of the two support rods 100 can be achieved by only a single locking action, without the need to spend time and effort to perform multiple locking or unlocking steps, and bring a faster, more convenient, time-saving and labor-saving use experience to the user.

[0031] In certain embodiments, reference Figure 2 The locking assembly 300 includes an operating member 310, a first locking member 320, a second locking member 600 and a transmission structure 800. The operating member 310 is movably connected to the outer periphery of the mounting tube 200. The operating member 310 is connected to the first locking member 320 and can drive the first locking member 320 to move closer to or away from one of the two support rods 100. The first locking member 320 is connected to the second locking member 600 through the transmission structure 800. When the first locking member 320 moves closer to one of the two support rods 100, the transmission structure 800 can drive the second locking member 600 to lock the other of the two support rods 100. After the operating member 310 moves, it will drive the first locking member 320 to move, and lock one of the two support rods 100 through the first locking member 320. In addition, when the first locking member 320 moves, it will also drive the second locking member 600 to move together through the transmission structure 800. Therefore, the first locking member 320 and the second locking member 600 can move synchronously under the action of the transmission structure 800, and can clamp or release the two support rods 100 synchronously, thereby achieving the purpose of synchronous locking or unlocking.

[0032] Specifically, the operating member 310 is a plate buckle, and the operating member 310 has a cam portion 315. The cam portion 315 is hinged to the outer periphery of the mounting tube 200, and when rotating, it pushes between the operating member 310 and the mounting tube 200 through its eccentric portion, thereby achieving the effect of driving the first locking member 320 to move.

[0033] In certain embodiments, reference Figure 3 , one of the first locking member 320 and the second locking member 600 moves along the radial direction of the installation cylinder 200 and clamps or loosens the support rod 100, and the other of the first locking member 320 and the second locking member 600 moves along the axial direction of the installation cylinder 200 and clamps or loosens the support rod 100. The first locking member 320 and the second locking member 600 move along the radial direction and the axial direction of the installation cylinder 200 respectively, so that the two will move in multiple dimensions in the installation cylinder 200, so as to achieve a larger range of movement effect within the inner cavity of the effective installation cylinder 200, so that the two can respectively realize the locking or unlocking of the two support rods 100.

[0034] Specifically, the first locking member 320 moves along the radial direction of the installation tube 200 and tightens and fixes the peripheral wall of the support rod 100. Of course, the first locking member 320 can also move along the axial direction of the installation tube 200. The specific implementation method can be adjusted accordingly according to actual needs and is not limited here.

[0035] In certain embodiments, reference Figure 3 The transmission structure 800 includes a transmission member 330 disposed in the installation cylinder 200. The first locking member 320 and the transmission member 330 are both provided with an inclined surface 400 and abut against each other through the inclined surface 400. The transmission member 330 is connected to the second locking member 600. When the first locking member 320 moves and pushes the transmission member 330, the transmission member 330 will move obliquely under the action of the inclined surface 400. The oblique movement includes multi-dimensional movement along the radial and axial directions of the installation cylinder 200, so that the second locking member 600 connected thereto can move in a dimension different from that of the first locking member 320, thereby achieving the effect that the first locking member 320 and the second locking member 600 move in the radial and axial directions of the installation cylinder 200 respectively.

[0036] It is conceivable that the transmission structure 800 may also include a spiral component and convert the rotational motion of the first locking member 320 into the sliding motion of the second locking member 600. The specific implementation can be adjusted accordingly according to actual needs and is not limited here.

[0037] In certain embodiments, reference Figure 3The transmission member 330 is threadedly connected with an adjusting knob 340, which is threadedly connected to the first locking member 320 and can cooperate with the transmission member 330 to adjust the distance between the first locking member 320 and the support rod 100. When the adjusting knob 340 is rotated, it will perform a spiral motion and change the relative distance between its end and the transmission member 330. Since the adjusting knob 340 passes through the first locking member 320, its end and the transmission member 330 will be located on both sides of the first locking member 320 and change the clamping force on the first locking member 320. Therefore, the locking force of the first locking member 320 can be adjusted by rotating the adjusting knob 340, so it has the advantage of easy operation.

[0038] In certain embodiments, reference Figure 4 The transmission member 330 is provided with a connecting rod 500, and the connecting rod 500 is connected with a nut 570; the second locking member 600 is provided with a transmission sleeve 700, and the connecting rod 500 can push the transmission sleeve 700 to move through the nut 570. The connecting rod 500 can transmit the movement of the transmission member 330 to the nut 570, and drive the nut 570 to move with the transmission member 330, so that the nut 570 can effectively push the transmission sleeve 700 and the second locking member 600 to move, thereby achieving a linkage effect between the first locking member 320 and the second locking member 600.

[0039] In certain embodiments, reference Figure 6 The second locking member 600 includes a fixing hoop 630 sleeved on the support rod 100. The fixing hoop 630 is provided with a deformation notch 670 and can be elastically contracted or elastically expanded at the deformation notch 670. The transmission structure 800 is used to drive the fixing hoop 630 to contract. When the transmission structure 800 does not drive the fixing hoop 630 to move, the deformation notch 670 can maintain an expanded state under its own elastic action, and the fixing hoop 630 can relax the support rod 100, so that the support rod 100 can slide smoothly. When the transmission structure 800 drives the fixing hoop 630 to move and contract, the fixing hoop 630 will contract at the deformation notch 670, and then the fixing hoop 630 will clamp and fix the support rod 100, thereby achieving the effect of fixing the support rod 100.

[0040] Specifically, a threaded portion 550 is disposed at the end of the connecting rod 500 , and the threaded portion 550 is threadedly connected to the nut 570 . The threaded portion 550 passes through the transmission sleeve 700 and positions it.

[0041] In certain embodiments, reference Figure 5, a fixing sleeve 690 is provided at the end of the mounting tube 200, and a fixing hoop 630 is movably connected in the fixing sleeve 690; the fixing sleeve 690 is provided with an inner conical surface 693, and the fixing hoop 630 is provided with an outer conical surface 635; the transmission structure 800 is connected to the fixing hoop 630 and can drive it to move relative to the fixing sleeve 690, so that the inner conical surface 693 and the outer conical surface 635 are pressed against each other. Driven by the transmission structure 800, the fixing hoop 630 will move relative to the fixing sleeve 690. In this process, the inner conical surface 693 and the outer conical surface 635 will contact and press against each other. At this time, the fixing hoop 630 will elastically contract under the force of the pressing, and clamp the support rod 100, thereby smoothly achieving the effect of locking the support rod 100.

[0042] In certain embodiments, reference Figure 6 The end of the support rod 100 is provided with a limit head 105, the radial dimension of the limit head 105 is larger than the radial dimension of the support rod 100, and the limit head 105 is used to prevent the support rod 100 from completely leaving the mounting tube 200. When the support rod 100 is about to leave the mounting tube 200, the limit head 105 can be clamped at the end of the mounting tube 200, thereby effectively preventing the support rod 100 from leaving the mounting tube 200, thereby achieving the effect of preventing the support leg from disassembling.

[0043] In certain embodiments, reference Figure 1 One of the two support rods 100 is provided with a foot pad 900. The foot pad 900 can effectively increase the anti-slip ability of the support rod 100 when it contacts the ground, and effectively avoid the problem of damage to the support rod 100.

[0044] The second aspect of the utility model provides an embodiment of a photographic pan head, including the above-mentioned legs. After the support rod 100 moves relative to the mounting tube 200 and extends into or out from the end of the mounting tube 200, the overall lengthening or shortening effect of the legs can be directly and effectively achieved. The two support rods 100 move from both ends of the mounting tube 200, respectively, so that the legs as a whole can be extended and retracted at least twice at the mounting tube 200, thereby providing a larger extension range to facilitate the adjustment of the position of the photographic equipment. After both support rods 100 move, the two support rods 100 can be fixed synchronously by the locking assembly 300. Therefore, the synchronous locking or unlocking of the two support rods 100 can be achieved only through a single locking action, without the need to spend time and effort to perform multiple locking or unlocking steps, and bring a faster, more convenient, time-saving and labor-saving use experience to the user.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0046] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
