[0032] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting 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.

[0033] Reference Figure 1A support mechanism includes: a main body 100, a support leg 300, a switch member 200, and an elastic member 700. The support leg 300 is rotatably mounted on the main body 100 and can be rotated to be flush with the main body 100 and then rotated and extended relative to the main body 100. The switch member 200 is disposed on the main body 100 and / or the support leg 300 and is connected to a locking structure 800. The switch member 200 can use the locking structure 800 to relatively fix or release the main body 100 and the support leg 300. The elastic member 700 is used to apply a reverse torque between at least one of the main body 100 and the support leg 300 and the support member 500 when the support leg 300 is retracted relative to the main body 100. When the photography stand needs to be transported, the support leg 300 can be flipped closer to the main body 100, so that the support leg 300 and the main body 100 are nearly flush, thereby maintaining a portable state. When the photography stand is in use, the legs 300 can be extended relative to the main body 100, with the bottoms of the legs 300 contacting the support surface to provide support. When the legs 300 are extended, the support members 500 provide relative support between the main body 100 and the legs 300. The elastic member 700 maintains the extended position of the support members 500, the main body 100, and the legs 300. This ensures that the main body 100 and legs 300 are more firmly supported after they are extended, effectively improving the stability of the support provided by the photography equipment stand.

[0034] Specifically, the main body 100 is cylindrical, and the legs 300 fit closely to the outer periphery of the main body 100 when folded. Of course, the main body 100 may also have other shapes, such as a prism. The specific implementation is not exclusive and can be adjusted accordingly based on actual circumstances, and is not intended to be limiting here.

[0035] It is envisioned that a locking structure such as a buckle or latch can be provided between at least one of the support member 500 and the support leg 300 and the main body 100, thereby locking the support leg 300 when the support leg 300 is in the retracted state to prevent the support leg 300 from automatically expanding under the action of the elastic member 700. The specific implementation is not exclusive and can be adjusted accordingly according to actual circumstances, and is not limited here.

[0036] In certain embodiments, reference Figure 2Both ends of the support member 500 are provided with pivot shafts 570, and the two ends of the support member 500 are rotatably connected to the main body 100 and the support leg 300 respectively through the pivot shafts 570. The rotatable installation of the pivot shafts 570 with the main body 100 and the support leg 300 allows the support member 500 to rotate relative to the main body 100 and the support leg 300, respectively, thereby ensuring that the support member 500 can smoothly adjust its orientation angle relative to the support leg 300 and the main body 100, so that the support member 500 can support the main body 100 and the support leg 300 when the support leg 300 is extended, and can also rotate to be flush with the support leg 300 and the main body 100 when the support leg 300 is retracted, thereby being adapted to different usage requirements.

[0037] It is contemplated that the support member 500 may rotate relative to only one of the main body 100 and the support leg 300, and when the support leg 300 is retracted, the support member 500 extends into the main body 100 or the support leg 300, interlacing with the main body 100 or the support leg 300. The specific implementation is not exclusive and can be adjusted accordingly according to actual circumstances, and is not limited here.

[0038] In certain embodiments, reference Figure 5 The elastic member 700 includes a torsion spring 750 mounted on the support member 500. The torsion spring 750 has at least two elastic arms 730; one of the elastic arms 730 abuts against the support member 500, and the other elastic arm 730 abuts against the support leg 300 or the main body 100. When the support member 500 rotates and retracts, it will produce a rotation effect relative to the support leg 300 and the main body 100, and this rotation effect will apply torque to the elastic arms 730 of the torsion spring 750. During this process, the torsion spring 750 will accumulate elastic potential energy. When the support leg 300 is deployed, the torsion spring 750 will apply torque between the support member 500, the support leg 300 and the main body 100 through the elastic arms 730, so that the three can be supported by the torque, thereby effectively ensuring that the deployed support leg 300 is in a stable state.

[0039] In certain embodiments, reference Figure 7The locking structure 800 includes a buckle 230 and a slot 395. One of the buckle 230 and the slot 395 is provided on the main body 100, and the other is provided on the leg 300. The buckle 230 engages with the slot 395 only when the leg 300 is rotated to be flush with the main body 100. When the leg 300 is rotated to be flush with the main body 100, the buckle 230 and the slot 395 are aligned, and the buckle 230 directly engages with the slot 395. As a result, the leg 300 can directly and quickly achieve relative fixation between the leg 300 and the main body 100 during the process of rotating to be flush, without requiring additional operation to secure the folded state. This simplifies operation and saves time and effort.

[0040] It is envisioned that when the support legs 300 are fully extended, the extended state of the support legs 300 can be fixed by a snap connection, or the support legs 300 can be directly limited so that the support legs 300 are maintained in the fully extended state under the combined action of the limiter and the elastic member 700. The specific implementation is not exclusive and can be adjusted accordingly according to actual circumstances, and is not limited here.

[0041] In certain embodiments, reference Figure 6 The switch member 200 is elastically mounted on the main body 100 and can slide relative to the main body 100. The latch 230 is provided on the switch member 200 and can move with it. The slot 390 is provided on the support leg 300. When the switch member 200 overcomes the elastic force and slides relative to the main body 100, the latch 230 moves out of the slot 395. When the support leg 300 rotates to be flush with the main body 100, the latch 230 becomes relatively flush with the slot 395 and, pushed by the support leg 300, engages the slot 395. When the switch member 200 is triggered and slides against the elastic force, the latch 230 leaves the slot 395. At this time, the elastic member 700 exerts force and drives the support leg 300 to expand. Therefore, by triggering the switch member 200, the support leg 300 and the main body 100 can be directly and effectively unlocked, which is convenient for operation.

[0042] Specifically, a support 250 is provided at the end of the main body 100; the switch member 200 is sleeved on the outer periphery of the support 250 and can slide relative to it. A push spring (not shown) is disposed within the switch member 200. When the switch member 200 is not actuated, the push spring continuously pushes the switch member 200, keeping it away from the main body 100. At this point, the latch 230 can engage with the latch slot 395. When the switch member 200 is actuated and overcomes the elastic force of the push spring, the switch member 200 drives the latch 230 away from the latch slot 395, thereby unlocking the switch.

[0043] Furthermore, the switch member 200 is movably mounted on the bottom end of the main body 100 and is configured to contact a supporting surface such as the ground. Since the switch member 200 is subjected to a reaction force from the ground when in contact with the ground, the switch member 200 automatically deploys when the photographic equipment stand is placed on the ground, further enhancing the convenience and speed of deploying the legs 300.

[0044] It is envisioned that the elastic force of the push spring can be adjusted to adjust the force required for the switch member 200 to contact the ground and unfold, thereby preventing the support leg 300 from being unlocked too easily. The specific implementation is not exclusive and can be adjusted accordingly based on actual circumstances, and is not limited here.

[0045] In certain embodiments, reference Figure 3 The support leg 300 is provided with a frame member 350, the ends of which are rotatably connected to the main body 100 and the support member 500, respectively; an elastic member 700 is disposed between the support leg 300 and the support member 500. The frame member 350 not only effectively increases the structural strength of the support leg 300, but also provides a connection position for the support member 500 to be rotatably connected, thereby ensuring that the support member 500 can be smoothly rotatably connected to the support leg 300. The positional relationship between the elastic member 700 and the frame member 350 effectively ensures that when the frame member 350 and the support member 500 move relative to each other, the frame member 350 is unlikely to interfere with the elastic member 700, thereby ensuring that the elastic member 700 and the frame member 350 can work smoothly.

[0046] In certain embodiments, reference Figure 6 The main body 100 is provided with a connection chamber 157, and the support member 500 is rotatably mounted in the connection chamber 157; the connection chamber 157 is provided with two support walls 153, one of which is used to abut the support member 500 when the support legs 300 are unfolded, and the other of the two support walls 153 is used to abut the support rod when the support legs 300 are rotated to be flush with the main body 100. The connection chamber 157 provides a mounting position for the support member 500 on the main body 100, thereby ensuring that the support member 500 can be smoothly connected to the main body 100. The two support walls 153 will respectively limit the forward and reverse rotation of the support member 500, thereby limiting the rotation range of the support member 500, thereby effectively preventing the support member 500 from detaching.

[0047] Specifically, a hook portion is provided at the end of the support member 500 , and the hook portion extends into the connecting chamber 157 and is rotatably connected to the main body 100 .

[0048] In certain embodiments, reference Figure 1The main body 100 is movably provided with a movable seat 900, which can slide back and forth along the length of the main body 100. The support leg 300 is rotatably connected to the movable seat 900. When the movable seat 900 slides relative to the main body 100, it will drive the support leg 300 to move relative to the main body 100. Therefore, when the support leg 300 is retracted to be flush with the main body 100, the movable seat 900 can drive the support leg 300 to slide in the length direction relative to the main body 100, so that the support leg 300 and the main body 100 can be stacked as much as possible, thereby effectively increasing the amount of space occupied by the main body 100 and the support leg 300 in the retracted state.

[0049] In certain embodiments, reference Figure 1 The movable base 900 is provided with a screw clamp 950 that can clamp the main body 100 and fix the main body 100 and the movable base 900 to each other. When the screw clamp 950 rotates, it can tighten or loosen the main body 100, thereby locking or unlocking the positional relationship between the main body 100, the movable base 900, and the support leg 300, thereby fixing the adjusted positional relationship.

[0050] Specifically, the spiral clamp 950 includes a fastening hoop arranged on the connecting seat, and the fastening hoop is sleeved on the outer periphery of the main body 100; the fastening hoop is provided with a deformation notch, and the fastening hoop can be telescopically deformed at the deformation notch and clamp or loosen the main body 100; the outer periphery of the fastening hoop is provided with a threaded inner sleeve and a threaded outer sleeve, and the threaded inner sleeve is provided on the outer periphery of the fastening hoop, and part of the deformation notch extends outside the threaded inner sleeve; the threaded outer sleeve is threadedly connected to the threaded inner sleeve, and the threaded outer sleeve can move close to the deformation notch and squeeze the deformation notch.

[0051] In certain embodiments, reference Figure 1 There are multiple legs 300, support members 500, and elastic members 700, each of which is distributed around the main body 100. The legs 300, support members 500, and elastic members 700 are connected one-to-one. The multiple legs 300 can provide multiple support points for the main body 100 from the lateral direction of the main body 100, so that the main body 100 can be firmly placed on the supporting surface under the joint support of the legs 300. The joint action of the support members 500 and elastic members 700 can also stabilize the main body 100, thereby effectively improving the support stability of the main body 100.

[0052] In certain embodiments, reference Figure 4 The end of the support leg 300 is provided with an anti-skid pad 390. The anti-skid pad 390 can effectively hinder the relative sliding between the support leg 300 and the supporting surface, so that the support leg 300 can be placed more firmly on the supporting surface and support the main body 100.

[0053] The second aspect of the present invention provides an embodiment of a photographic equipment stand, comprising the above-mentioned support mechanism. When the photographic stand needs to be transported, the legs 300 can be flipped close to the main body 100, and the legs 300 and the main body 100 are made nearly flush, so that the photographic stand can remain in a portable state. When the photographic stand needs to be used, the legs 300 can be unfolded relative to the main body 100, and the support effect can be achieved by the bottom of the legs 300 contacting the support surface. When the legs 300 are unfolded, the support member 500 will provide relative support between the main body 100 and the legs 300, and maintain the relative unfolded state between the support member 500 and the main body 100 and the legs 300 under the action of the elastic member 700. As a result, after the main body 100 and the legs 300 are unfolded, the unfolded state will be more firmly maintained, thereby effectively improving the support stability of the photographic equipment stand for the photographic equipment.

[0054] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned 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.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
