[0050] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0052] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present invention, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that ordinary technicians in this field can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0053] See Figure 1 and Figure 2 When the support legs are fully extended, the support legs 2 are used to support the main pole 1, and the main pole 1 can be connected with shooting equipment, mobile phones, fill lights, etc.; therefore, the support legs 2 are more common in live broadcast and shooting scenes; when use is finished, the free ends of the support legs 2 can be folded back to the main pole 1 for easy carrying; as described in the background technology, when the existing support legs are needed, the elastic locking mechanism can be directly pressed to unlock the support legs 2, but in this unlocked state, the support legs 2 will not automatically extend, but will only extend slightly from the position where they are in contact with the main pole; it is still necessary to manually rotate the support legs to fully extend the support legs 2 to a state where they can stably support the main pole 1.

[0054] In order to solve the above problems, the present invention proposes a support stand that can be fully opened. Figure 3 , which includes

[0055] Main rod 1; the main rod 1 is provided with a connecting seat 5

[0056] A support leg 2 that can be deployed or retracted; one end of the support leg 2 is rotatably connected to the connecting seat 5, and the other end is a free end; when the free end of the support leg 2 is close to the main rod, the support leg 2 is retracted, and when the free end of the support leg 2 is away from the main rod 1, the support leg 2 is deployed;

[0057] Locking assembly 3; the locking assembly 3 is used to adapt to the free end of the supporting leg 2 when the supporting leg 2 is folded, thereby limiting the movement of the supporting leg 2 relative to the main rod 1, and the locking assembly 3 releases the restriction after being triggered;

[0058] Reinforcing rib 4; one end of the reinforcing rib 4 is rotatably connected to the supporting foot 2, and the other end is rotatably connected to the main rod 1 or the locking assembly 3; and a first elastic member 42 is provided between the reinforcing rib 4 and the supporting foot 2. When the free end of the supporting foot 2 is adapted to the locking assembly 3, the first elastic member 42 undergoes elastic deformation and generates a restoring force; when the locking assembly 3 is released from the restriction, the restoring force of the first elastic member 42 causes the free end of the supporting foot 2 to move away from the main rod 1 and fully unfold.

[0059] In this embodiment, the tripod is fully unfolded when the supporting legs 2 are unfolded to a state where they can support or stably support the main pole 1. Generally speaking, when the tripod is fully unfolded, the supporting legs 2 need to rotate a large angle, and the elastic locking mechanism in the prior art only releases the supporting legs 2, but cannot allow the supporting legs to automatically unfold, let alone automatically fully unfold.

[0060] In this embodiment, the locking assembly 3 may be triggered by pressing, rotating, or impacting.

[0061] Compared with the prior art, one end of the reinforcing rib 4 of the present invention is rotatably connected to the supporting foot 2, and the other end is rotatably connected to the main rod 1 or the locking assembly 3; and a first elastic member 42 is provided between the reinforcing rib 4 and the supporting foot 2. When the free end of the supporting foot 2 is adapted to the locking assembly 3, the first elastic member 42 undergoes elastic deformation to generate a restoring force; when the locking assembly 3 is released, the free end of the supporting foot 2 moves away from the main rod 1 under the action of the restoring force and is fully unfolded; through the ingenious design of the first elastic member 42, the problem in the prior art that after the locking assembly 3 is released, the supporting foot 2 is only in a slightly expanded state and still needs to be manually rotated to fully unfold is solved; after the locking assembly 3 is released by the present practical solution, the entire supporting tripod can be fully unfolded, which is more convenient to use.

[0062] In this embodiment, the number of supporting legs of the supporting leg frame 2 is 3, but it should be understood that it is not limited to this, and it can also be 4, 5 or other numbers.

[0063] See Figure 4-Figure 6 The reinforcing rib 4 is provided with a first rotating shaft 41, which is rotatably connected to the supporting foot 2; the first elastic member 42 is a torsion spring, which is sleeved on the first rotating shaft 41; when the free end of the supporting foot 2 is adapted to the locking assembly 3, the torsion spring is twisted and generates a torsional force; when the locking assembly is released, the torsional force provided by the torsion spring causes the free end of the supporting foot 3 to move away from the main rod 1 and fully unfold.

[0064] The first rotating shaft 41 and the reinforcing rib 4 may be an integrated structure. The first rotating shaft 41 is rotatably connected to the supporting leg 2 , that is, the reinforcing rib 4 may be rotatably connected relative to the supporting leg 2 .

[0065] In this embodiment, at least two first grooves 44 are provided on the supporting foot 2, and the two ends of the first rotating shaft 41 are respectively inserted into the first grooves 44, forming a structure in which the first rotating shaft 41 rotates in the first grooves 44; the two ends of the first rotating shaft 41 protrude from the reinforcing rib 4, and the protruding parts at the two ends can be respectively inserted into the first grooves 44.

[0066] An easily conceivable equivalent solution is to provide other detachable additional structures on the supporting foot 2, and to set the first groove 44 on the detachable additional structure; this type of solution should be regarded as equivalent to directly setting the first groove 44 on the supporting foot; for example, a limit block 43 is provided on the supporting foot, and the first groove 44 is set on the limit block 43.

[0067] In a preferred embodiment, a limit block 43 is also provided on the supporting foot 2; the limit block 43 is arranged at the opening of the first groove 44, and is used to limit the first rotating shaft 41 from sliding out of the first groove 44; the first groove 44 is a slot on the supporting foot 2, and the limit block 43 can be removed relative to the supporting foot 2. In this way, during the production process, when installing the first rotating shaft 41, the first rotating shaft 41 can be first inserted into the opening of the first groove 44, and then the limit block 43 can be connected to the supporting foot 2 to seal the opening of the first groove 44 and limit the first rotating shaft 41 from sliding out of the first groove 44; production and processing are more convenient; in this example, the cross-section of the first groove 44 is a U-shaped structure. During installation, the first rotating shaft 41 is inserted into the first groove 44 from the U-shaped opening, and the limit block 43 is arranged at the opening of the U-shaped structure.

[0068] In a preferred embodiment, the torsion spring includes a main body 420 and a first lever arm 422 and a second lever arm 421 extending from the main body 420 . The main body is sleeved on the first rotating shaft 41 , the first lever arm 422 abuts against the supporting foot 2 , and the second lever arm 421 abuts against the reinforcing rib 4 .

[0069] In this embodiment, a first through hole 431 is provided on the limit block 43, and the torsion spring includes a main body 420 and a first force arm 422 and a second force arm 421 extending from the main body 420. The first force arm 422 is limited after passing through or abutting the first through hole 431, and a second through hole is provided on the reinforcing rib 4, and the second force arm 421 passes through or abuts the second through hole; the second force arm 421 is limited on the reinforcing rib 4; when the free end of the supporting foot 2 is adapted to the locking assembly 3, the first force arm 422 and the second force arm 421 are twisted, and a torsional force is generated thereby. When the locking assembly 3 releases the restriction on the free end of the supporting foot 2, the torsional force causes the supporting foot 2 to rotate and fully unfold.

[0070] An easily conceivable equivalent solution is to directly set the first through hole on the supporting foot 2; or not to set the through hole, and the first force arm 422 directly abuts against the limit block 43; or to modify the through hole into a groove structure; this type of solution should be regarded as equivalent to setting the first through hole 431 on the limit block to abut against the first force arm 422.

[0071] In this embodiment, the reinforcing ribs 4 are provided corresponding to the supporting legs 2 ; each supporting leg 2 is provided with a corresponding reinforcing rib 4 .

[0072] In this embodiment, the connecting seat sleeve 5 is provided on the main rod 1 , and when the supporting legs 2 are folded or unfolded, the connecting seat 5 can slide relative to the main rod 1 .

[0073] See Figure 7-11 The locking assembly 3 includes a fixing seat 32, a trigger button 31 and a second elastic member 34; the fixing seat 32 is connected to the main rod 1; the second elastic member 34 is arranged between the trigger button 31 and the fixing seat 32; and a locking structure is provided at one end of the trigger button 31. When the supporting leg 2 is retracted, the locking structure is used to limit the movement of the supporting leg 2 relative to the main rod 1, that is, to limit the expansion of the supporting leg 2; when the trigger button 31 is pressed, the locking structure moves, releasing the restriction on the supporting leg 2.

[0074] In this embodiment, the locking mechanism is activated by pressing, releasing the restraint and avoiding the need for forcible separation of the support leg 2 and the main rod 1. This ingenious structural design includes the fixing base 32, which can be integral with the main rod 1 or two separate structures connected by bonding, bolts, or the like. The second elastic member 34 can be a spring or a spring.

[0075] In this embodiment, one end of the fixing seat 32 is connected to the main rod 1, and the other end is provided with a second groove. One end of the second elastic member 34 is accommodated in the second groove and abuts against the bottom of the second groove, and the other end is sleeved on the trigger button 31 or abuts against the trigger button 31.

[0076] When the trigger button 31 is pressed, the second elastic member 34 is compressed, and the trigger button 31 is displaced, driving the locking structure to move; after releasing the trigger button 31, under the action of the second elastic member 34, the trigger button 31 drives the locking structure to return to its initial position, and a second press or impact can be performed.

[0077] In this embodiment, in addition to pressing, you can also directly throw the supporting leg to the ground, let the ground hit the trigger button 31. After the trigger button 3 is subjected to pressure from the ground, it compresses the second elastic member 34 and releases the restriction on the free end of the supporting leg; then, under the action of the torsion spring, it automatically bounces open and fully unfolds; the whole process is very convenient.

[0078] In this embodiment, in order to better limit the second elastic member 34 to be compressed only in the axial direction, a limit cover 33 is further provided. The limit cover 33 is arranged above the groove of the fixing seat 32, and forms an accommodating space with the groove of the fixing seat 32, and the second elastic member 34 is located in the accommodating space; and the cross-section of the accommodating space is slightly larger than the cross-section of the second elastic member 34, ensuring that the second elastic member 34 can only be compressed or stretched along its own axial direction; the preferred second elastic member 34 is a spring; the limit cover 33 in this embodiment is provided with an opening, and the end of the trigger button 31 that is not covered with the second elastic member 34 extends out from the opening; a structure is formed in which the trigger button 31 can be extended into the accommodating cavity.

[0079] A pressing cap is provided on the top of the end of the trigger button 31 that is not sleeved with the second elastic member 34 to facilitate pressing.

[0080] In this embodiment, an extension portion 313 is provided at one end where the trigger button 31 and the second elastic member 34 are sleeved. The extension portion 313 surrounds the trigger button 31 axially, and a locking structure is provided on the extension portion 313. When the trigger button 31 compresses the elastic button, the locking portion is driven to move in the direction of compressing the second elastic member 34. After the locking portion moves, the restriction on the supporting foot 2 can be released.

[0081] The engaging structure comprises a first protrusion 312 and a second protrusion on the support leg 2. The first and second protrusions abut against each other, restricting the movement of the support leg 2 relative to the main rod 1. Pressing the trigger button 31 causes the first protrusion 312 to move downward, separating from the second protrusion, releasing the restraint on the support leg 2. When the trigger button 31 is released, the first protrusion 312 moves upward under the restoring force of the second elastic member 34, returning to its original locked position. In this embodiment, when in the locked position, the first protrusion 312 passes through the limit cover and abuts against the second protrusion.

[0082] In this embodiment, when the supporting leg 2 needs to be folded, the supporting leg 2 can be directly manually rotated closer to the main pole 1; during the folding process, the second protrusion 21 on the supporting leg first moves along the inclined surface of the first protrusion 312, pressing down the first protrusion 312. After the supporting leg 2 is completely folded, the first protrusion 312 pops out again and returns to the locked position, abutting against the second protrusion 21 to limit the expansion of the supporting leg 2.

[0083] See Figure 12 In this embodiment, in order to help the supporting leg 2 to be fully unfolded, an extrusion block 311 is provided on the side of the end of the trigger button 31 that is not covered with the second elastic member 34. When the trigger button 31 is pressed, the locking structure releases the restriction on the supporting leg 2, and the extrusion block 311 moves with the trigger button 31, squeezing the supporting leg 2, so that the supporting leg 2 moves in the direction of unfolding, helping the supporting leg 2 to be fully unfolded.

[0084] In this embodiment, the squeezing block 311 is protruding from the side of the trigger button 31 and has a sloped structure; the slope is used to guide the supporting foot 2 to move along the slope when the squeezing block 311 moves; the squeezing block 311 contacts the supporting foot 2, and when the supporting foot 2 is squeezed away from its original position, the contact point on the supporting foot 2 with the squeezing block 311 is the squeezing point; when the trigger button 31 is not pressed, the squeezing block 311 does not contact the squeezing point. After pressing the trigger button 31, the squeezing point moves relative to the slope of the squeezing block 311, and the supporting foot 2 gradually leaves the original locked position until the squeezing point can no longer squeeze the supporting foot 2.

[0085] In this embodiment, a connecting seat is provided on the main rod 1, one end of the supporting foot 2 is rotatably connected to the connecting seat 5, and the other end is a free end. When the free end of the supporting foot 2 is adapted to the locking assembly 3, the supporting foot 2 is in a retracted state. When the free end of the supporting foot 2 is not adapted to the locking assembly 3, the supporting foot 2 is in an expanded or expandable state.

[0086] In this embodiment, one end of the reinforcing rib is rotatably connected to the supporting leg 2, and the other end is rotatably connected to the fixing seat 32 or directly rotatably connected to the main rod 1; the reinforcing rib can greatly improve the stability of the supporting leg 2 frame.

[0087] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
