[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] This utility model embodiment provides a support stand 100, such as Figures 1 to 6As shown, the device includes a support rod 1, a sliding assembly 2, a fixed base 3, at least three support foot assemblies 4, and a locking structure 5. The sliding assembly 2 is slidably sleeved on the support rod 1, the fixed base 3 is fixed to the bottom end of the support rod 1, and the support foot assembly 4 includes a support foot 41 and a support rib 42. One end of the support foot 41 is rotatably connected to the sliding assembly 2, one end of the support rib 42 is rotatably connected to the inner wall of the support foot 41, and the other end of the support rib 42 is rotatably connected to the fixed base 3. The locking structure 5 includes a locking element 51, a first elastic element 53, and a control button 52. The control button 52 is movably disposed on the fixed base 3, and the locking element 51 slides against the inner wall of the other end of the support foot 41. The first elastic element 53 is disposed on the inner wall of the other end of the support leg 41 along the length direction of the support leg 41, and the two ends of the first elastic element 53 are respectively connected to one end of the locking element 51 and the inner wall of the support leg 41. The locking element 51 is provided with a locking hook part 5111, and the fixed base 3 is provided with a locking block 311. When the folded state is reached, the locking hook part 5111 is locked with the locking block 311. The control button 52 is used to drive the other end of the locking element 51 to move so that the locking hook part 5111 disengages from the locking block 311, and the support leg assembly 4 unfolds.

[0028] Specifically, the sliding assembly 2 is slidably sleeved on the support rod 1, the fixed seat 3 is fixed to the bottom end of the support rod 1, and the support foot assembly 4 includes a support foot 41 and a support rib 42. One end of the support foot 41 is rotatably connected to the sliding assembly 2, one end of the support rib 42 is rotatably connected to the inner wall of the support foot 41, and the other end of the support rib 42 is rotatably connected to the fixed seat 3. Thus, the support foot 41, the support rib 42, and the sliding assembly 2 can be linked together, so that the support foot 41 and the support rib 42 can be retracted outside the wall of the support rod 1 or extended to support an object.

[0029] More specifically, the locking member 51 is slidably connected to the inner wall of the other end of the support leg 41. The locking member 51 is provided with a locking hook portion 5111, and the fixed base 3 is provided with a locking block 311. When the locking hook portion 5111 is locked with the locking block 311, each support leg 41 can be fixed on the fixed base 3, so that the support leg 41 and the support rib can be folded up outside the wall of the support rod 1 for easy storage. The control button 52 is movably disposed on the fixed base 3, so that the user can easily and conveniently release the locking member 51 from the fixed base 3 by pressing the control button 52, so that the support leg assembly 4 can disengage from the folded state and be initially unfolded. Specifically, when the control button 52 is pressed, the control button 52 will move along the fixed base 3 and drive the other end of the locking member 51 to move along the inner wall of the support leg 41, so that the locking hook portion 5111 of the locking member 51 disengages from the locking block 311 of the fixed base 3, so that the support leg 41 can disengage from the fixed base 3 and be initially unfolded.

[0030] It is worth mentioning that, in a specific usage method, since the control button 52 is located at the bottom of the support rod 1, it is only necessary to place the support rod 1 vertically on the placement platform (such as the ground and tabletop) and apply downward pressure to the support rod 1 to press the control button 52 so that the support leg 41 can disengage from the retracted state and initially unfold, thereby improving the user's ease of operation.

[0031] In addition, the first elastic member 53 is disposed on the inner wall of the other end of the support foot 41 along the length direction of the support foot 41, and the two ends of the first elastic member 53 are respectively connected to one end of the locking member 51 and the inner wall of the support foot 41. Thus, when the locking hook 5111 disengages from the locking block 311, the first elastic member 53 can make the locking member 51 automatically reset.

[0032] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5 As shown, along the length of the support leg 41, the inner wall of the other end of the support leg 41 is provided with a sliding space 411. The locking member 51 includes a first end 511 and a second end 512. The first end 511 is slidably accommodated in the sliding space 411. The locking hook 5111 is provided at the first end 511, and both the locking hook 5111 and the second end 512 are exposed outside the sliding space 411. The first elastic member 53 is located between the first end 511 and the side of the sliding space 411 away from the second end 512. The control button 52 is used to drive the second end 512 to slide into the sliding space 411 so that the locking hook 5111 disengages from the locking block 311.

[0033] Specifically, the first end 511 is slidably accommodated in the sliding space 411, the locking hook 5111 is provided on the first end 511, and both the locking hook 5111 and the second end 512 are exposed outside the sliding space 411. Thus, when the control button 52 is pressed, the control button 52 can drive the second end 512 to slide into the sliding space 411, thereby causing the locking hook 5111 on the first end 511 to move, so that the locking hook 5111 disengages from the locking block 311.

[0034] Furthermore, the first elastic member 53 is located between the first end 511 and the side of the sliding space 411 away from the second end 512. Thus, when the second end 512 slides into the sliding space 411, the first end 511 can press against the first elastic member 53, so that after the locking hook 5111 disengages from the locking block 311, the first elastic member 53 can push the first end 511, thereby causing the second end 512 to slide out of the sliding space 411, so that the locking member 51 can automatically reset.

[0035] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5As shown, the inner wall of the support foot 41 is provided with a first slide rail 412, a blocking block 413 and a mounting block 414. The mounting block 414, the first slide rail 412 and the blocking block 413 enclose and define a sliding space 411. The first end 511 is slidably disposed along the first slide rail 412. The blocking block 413 is provided with a first clearance opening 4131. The width of the first end 511 is greater than the width of the first clearance opening 4131. The second end 512 passes through the first clearance opening 4131.

[0036] Specifically, the mounting block 414, the first slide rail 412, and the blocking block 413 can enclose and define the sliding space 411, so that the first end 511 can be accommodated in the first slide rail 412 and slide along the first slide rail 412. The blocking block 413 is provided with a first clearance opening 4131, and the width of the first end 511 is greater than the width of the first clearance opening 4131, thereby preventing the first end 511 from sliding out of the first slide rail 412. The second end 512 passes through the first clearance opening 4131, so that the second end 512 can be exposed outside the sliding space 411, so that the control button 52 can drive the second end 512 to move into the sliding space 411, thereby causing the first end 511 to slide along the first slide rail 412, so that the locking hook portion 5111 on the first end 511 disengages from the locking block 311.

[0037] More specifically, the mounting block 414 has an opening facing the locking block 311, through which the locking hook portion 5111 can be exposed outside the sliding space 411, and as the first end portion 511 and the second end portion 512 move, it can lock or disengage from the locking block 311.

[0038] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5 As shown, the blocking block 413 is provided with a first abutting part 4132, and the mounting block 414 is provided with a second abutting part 4141. The first abutting part 4132 abuts against the second abutting part 4141 to fix the mounting block 414.

[0039] Specifically, one end of the mounting block 414 abuts against the first abutment 4132 on the blocking block 413 via the second abutment 4141 for fixation, and the other end of the mounting block 414 is fixed to the inner wall of the support foot 41 by screws. Compared to fixing both ends of the mounting block 414 with screws, the first abutment 4132 and the second abutment 4141 increase the fixing area between the mounting block 414 and the blocking block 413, thereby increasing the stability of the mounting block 414 installation. On the other hand, it allows for quick and convenient installation or removal of the mounting block 414, so that it can be easily replaced when the locking member 51 or the first elastic member 53 fails.

[0040] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figures 3 to 5 As shown, a second slide rail 415 is also provided on the inner wall of the support foot 41. The second slide rail 415 is connected to the first clearance opening 4131, and the second end 512 is slidably arranged along the second slide rail 415.

[0041] Specifically, the second slide rail 415 communicates with the first clearance opening 4131, and the second end 512 is slidably disposed along the second slide rail 415. Thus, the second slide rail 415 can guide the second end 512, so that after the control button 52 pushes the second end 512, the second end 512 can slide smoothly along the second slide rail 415 and stably drive the first end 511 in the sliding space 411 to slide along the first slide rail 412, thereby ensuring that the locking hook part 5111 can smoothly disengage from the locking block 311.

[0042] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 1 and Figure 6 As shown, the sliding assembly 2 includes a sliding seat 21, a connecting seat 22, and a third elastic member 23. The sliding seat 21 and the connecting seat 22 are both slidably sleeved on the support rod 1. An installation space 24 is defined between the sliding seat 21 and the support rod 1. The connecting seat 22 and the third elastic member 23 are both located within the installation space 24. The sliding seat 21 has a limiting part 211 at one end near the fixed seat 3. The two ends of the third elastic member 23 are respectively connected to the limiting part 211 and the connecting seat 22. The support rod 1 has a limiting protrusion 11, which is located within the installation space 24 at the other end near the sliding seat 21. In the retracted state, the limiting protrusion 11 abuts against the connecting seat 22.

[0043] Specifically, in the retracted state, the other end of the support leg 41 is fixed to the fixed base 3 by the locking member 51. Since one end of the support leg 41 is connected to the sliding base 21, and the end of the sliding base 21 near the fixed base 3 is provided with a limiting part 211, the support leg 41 can abut against the sliding base 21, thereby ensuring that the limiting part 211 of the sliding base 21 can abut against the third elastic member 23 in the direction near the fixed base 3, so as to prevent the sliding base 21, the connecting base 22 and the third elastic member 23 from moving toward the fixed base 3. In addition, since the limiting protrusion 11 is located in the mounting space 24 near the other end of the sliding base 21, and the limiting protrusion 11 abuts against the connecting base 22, the limiting protrusion 11 can abut against the connecting base 22 in the direction away from the fixed base 3, so as to prevent the sliding base 21, the connecting base 22 and the third elastic member 23 from moving away from the fixed base 3, thereby fixing the sliding assembly 2, so that the support leg assembly 4 can be stably in the retracted state.

[0044] More specifically, when the control button 52 is pressed, the locking hook 5111 disengages from the locking block 311, and the other end of the support leg 41 disengages from the fixed seat 3, allowing the support leg assembly 4 to disengage from the retracted state and initially unfold. This releases the restriction of the support leg 41 on the sliding seat 21. Consequently, under the elastic force of the third elastic member 23, the third elastic member 23 can automatically push the sliding seat 21 and the connecting seat 22 toward the fixed seat 3, thereby causing the support leg assembly 4 to fully unfold. By implementing this embodiment, the support leg 100 can automatically unfold the support leg assembly 4 simply by pressing the control button 52, thereby reducing the user's manual steps of releasing the fixation of each support leg and pushing each support leg and support rib 42 to slide and unfold along the support rod 1, effectively improving the convenience and efficiency of the operation of the support leg 100.

[0045] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3 As shown, the control button 52 includes a slide rod 521 and an actuating piece 522. One end of the slide rod 521 is slidably disposed in the fixed base 3. A second elastic element 523 is sandwiched between one end of the slide rod 521 and the fixed base 3. The other end of the slide rod 521 is at least partially exposed outside the fixed base 3 and is connected to the actuating piece 522 so that the actuating piece 522 drives the locking member 51 to disengage from the fixed base 3.

[0046] Specifically, one end of the slide rod 521 is slidably disposed within the fixed base 3, while the other end of the slide rod 521 is at least partially exposed outside the fixed base 3 and connected to the actuating piece 522. The actuating piece 522 increases the pressing area of ​​the control button 52, facilitating the pressing of the control button 52. By pressing the actuating piece 522, one end of the slide rod 521 can slide into the fixed base 3, and during the sliding process, the actuating piece 522 can abut against the locking member 51, thereby driving the locking member 51 to move, causing the locking hook 5111 to disengage from the lock, thereby unlocking the support leg assembly 4 and allowing the support leg assembly 4 to initially unfold.

[0047] Furthermore, since a second elastic element 523 is sandwiched between one end of the slide bar 521 and the fixed base 3, when the touch piece 522 is pressed to slide one end of the slide bar 521 into the fixed base 3, the slide bar 521 will compress the second elastic element 523. Thus, when the touch piece 522 is released, the second elastic element 523 can allow one end of the slide bar 521 to slide out of the fixed base 3, so that the control button 52 can automatically reset.

[0048] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 3As shown, the fixed base 3 is provided with a first sliding groove 312 and a second sliding groove 321 that are connected. The bottom of the first sliding groove 312 is provided with a second clearance opening 313. One end of the sliding rod 521 passes through the second clearance opening 313. One end of the sliding rod 521 is provided with a limiting member 524, and the limiting member 524 is located in the second sliding groove 321, so that one end of the sliding rod 521 is slidably disposed in the second sliding groove 321, and the other end of the sliding rod 521 is slidably disposed along the first sliding groove 312. The second elastic member 523 is disposed between the other end of the sliding rod 521 and the bottom of the first sliding groove 312.

[0049] Specifically, one end of the slide rod 521 is provided with a limiting member 524, which is located within the second slide groove 321. The limiting member 524 allows one end of the slide rod 521 to slide within the second slide groove 321, ensuring that the control button 52 will not detach from the fixed base 3, thus helping to ensure the stability and reliability of the control button 52. The bottom of the first slide groove 312 is provided with a second clearance opening 313. One end of the slide rod 521 passes through the second clearance opening 313, allowing the other end of the slide rod 521 to slide along the first slide groove 312 while one end slides along the second slide groove 321, thereby increasing the stability of the slide rod 521. Furthermore, a second elastic member 523 is provided between the other end of the slide rod 521 and the bottom of the first slide groove 312, so that after the touch piece 522 is released, the second elastic member 523 can drive the control button 52 to automatically reset.

[0050] Furthermore, as one specific implementation method in some embodiments of this utility model, such as Figure 4 and Figure 5 As shown, the inner wall of the support foot 41 is provided with a receiving groove 416, and the support rib 42 is rotatably received in the receiving groove 416.

[0051] Specifically, by implementing this embodiment, when the support leg assembly 4 is folded up on the support rod 1, the support rib 42 can be accommodated in the receiving groove 416. This reduces the space occupied by the support rib 42, making the entire support leg 100 more compact in the folded state, which is convenient for storage and carrying. On the other hand, the receiving groove 416 can limit the support rib 42, preventing the support rib 42 from moving in the folded state and improving the stability of the folded support leg assembly 4.

[0052] This utility model also discloses a shooting assistance device, which includes a clamping mechanism and the aforementioned support tripod 100. The clamping mechanism is connected to the support rod 1 for fixing the shooting equipment. The beneficial effects of using the aforementioned support tripod 100 in the shooting assistance device have been described above when discussing the support tripod 100, and will not be repeated here.

[0053] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
