Description

Technical Field

[0001] This utility model relates to the field of photographic and video equipment technology, and in particular to a foot support device and a photographic support frame for a camera stand. Background Technology

[0002] In the fields of photography and filmmaking, single-pole shooting equipment (such as selfie sticks, monopods, and portable light stands) often uses omnidirectional feet to adjust the angle of the equipment. These feet must simultaneously meet the core requirements of rapid adjustment flexibility and stable reset capability.

[0003] Currently, the top of the foot support integrates a ball-and-socket assembly, containing a multi-directionally deflectable ball. The angle is fixed by tightening the locking knob to compress the ball. In the unlocked state, the ball can freely deflect within the socket, achieving three-dimensional adjustment of pitch, roll, and yaw. This structure is widely used due to its high degree of adjustment freedom and controllable cost.

[0004] Although the omnidirectional ball joint provides multi-directional adjustment capabilities, its lack of directional memory leads to a serious operational bottleneck. Specifically, when the user adjusts the tilt angle (such as tilting the device 30° for shooting), if it is necessary to quickly restore it to the initial vertical state, the ball joint angle needs to be repeatedly corrected, adjusted multiple times, and then locked again, which is very cumbersome.

[0026] Reference Figure 1 , Figure 2 and Figure 3 This utility model embodiment provides a foot support device 20 for a camera bracket, which includes: Ball head seat 100 has a receiving cavity 101, and a positioning component 110 is provided at one end of the cavity. The positioning component 110 includes a top plate 111, and a positioning hole 111b is provided on the top plate 111. The ball head 200 has a ball part 201 and a connecting section 202 connected together. The ball part 201 is rotatably housed in the receiving cavity 101 and abuts against the top plate 111. The connecting section 202 is used to connect a branch pipe. The ball part 201 and the connecting section 202 are provided with a through hole 202a. A locking member 210 is provided in the through hole 202a. The locking member 210 can selectively extend into the positioning hole 111b. The operating component 300 includes a stop member 330, which abuts against the end of the locking member 210 opposite to the positioning component 110. The operating component 300 can drive the stop member 330 to move so as to abut the locking member 210 into the positioning hole 111b, thereby fixing the ball joint 200 and the ball joint seat 100 relative to each other.

[0027] In this embodiment, the main function of the ball joint 100 is to provide an installation location for the ball head 200. Specifically, the ball joint 100 can be cylindrical, square, elliptical, etc., and its internal shape is a receiving cavity 101 adapted to the shape of the ball part 201 of the ball head 200. The ball joint 100 has an open end 100a and a mounting end 100b arranged opposite to each other. The open end 100a is mainly used to expose the connecting section 202 of the ball head 200 and part of the ball part 201, so as to realize the effect that the ball head 200 can swing freely within the ball joint 100. The mounting end 100b of the ball joint 100 is equipped with a positioning component 110. The main function of the positioning component 110 is to cooperate with the locking component 210 provided inside the ball head 200 to realize the quick vertical locking of the ball head 200 and the ball joint 100. Specifically, the positioning component 110 includes a top plate 111, which can be a circular plate, a square plate, or the like. The top plate 111 is provided with a positioning hole 111b that is coaxial with the ball head seat 100. The positioning hole 111b can be a circular hole, a slotted hole, or the like, and the hole diameter is adapted to the cross-sectional dimensions of the locking member 210.

[0028] In this embodiment, the ball joint 200 primarily serves as a connector and angle adjuster. The ball joint 200 comprises a connected ball portion 201, a connecting section 202, and a through hole 202a penetrating both the ball portion 201 and the connecting section 202. The ball portion 201 can be a standard sphere, ellipsoid, or other shape. It is rotatably mounted within the ball joint seat 100 and abuts against the top plate 111, enabling multi-angle adjustment. The connecting section 202 is rod-shaped and extends away from the open end 100a, serving to connect a telescopic tube or other photographic equipment support components. A locking element 210, adapted to the positioning hole 111b, is provided within the through hole 202a penetrating both the ball portion 201 and the connecting section 202. The locking element 210 can be a ball, a locking pin, a locking block, or the like, and its shape matches the positioning hole 111b.

[0029] In this embodiment, the operating component 300 is primarily for user operation. Specifically, the user can use the operating component 300 to insert the locking member 210 into the positioning hole 111b, thereby vertically fixing the ball joint 200 relative to the ball joint seat 100. The operating component 300 is located in the connecting section 202 and includes a stop member 330 extending into the through hole 202a. The stop member 330 abuts against the end of the locking member 210 facing away from the positioning component 110. The stop member 330 can be in the form of a stop rod 332, a push rod, a pin, etc. Simultaneously, the operating component 300 can also have a locking function, maintaining the locking member 210 inserted into the positioning hole 111b. The operating component 300 can be in the form of a lever, a push button, a knob 113, a support arm, a slider, etc., that pushes the stop member 330. Under external force, the stop member 330 pushes the locking member 210 into the positioning hole 111b, achieving a quick locking function.

[0030] In the unlocked state, the locking element 210 is in the position of exiting the positioning hole 111b. At this time, the ball part 201 can rotate and swing in all directions within the ball head seat 100, allowing the user to adjust the angle at any angle. The angle can be fixed using a conventional ball head rod 200 locking structure, such as a locking nut or a clamping mechanism, which will not be described in detail here.

[0031] Since the camera bracket foot support device in this embodiment is mainly used for monopod camera poles, it is often necessary to quickly restore it to a vertical position during use to ensure shooting stability. When quick vertical positioning is required, the user first releases the locking state of the ball part 201, and then roughly adjusts the ball head rod 200 and the ball head seat 100 to be relatively vertical. At this time, the locking member 210 can naturally fall into the positioning hole 111b under the action of gravity, achieving preliminary vertical positioning. To obtain better vertical positioning effect and locking reliability, elastic members can also be used for assistance, such as setting a spring in the through hole 202a to push the locking member 210, or setting a return spring on the operating component 300. The user controls the action of the abutment member 330 through the operating component 300. When locking is required, the abutment member 330 pushes the locking member 210 forward to fully extend into the positioning hole 111b; when unlocking is required, the abutment member 330 retracts, the locking member 210 disengages from the positioning hole 111b, and the ball head rod 200 returns to a free swing state.

[0032] The beneficial effects of this utility model are as follows: The ball part 201 of the ball head 200 is rotatably mounted within the ball head seat 100, enabling multi-angle adjustment of the foot support assembly to meet different terrain and shooting needs; By providing a through hole 202a in the ball part 201 and the connecting section 202, and slidingly installing a locking member 210 within the through hole 202a, combined with the abutment plate 111 and positioning hole 111b of the positioning assembly 110, and the cooperation of the abutment member 330 of the operating assembly 300, the user can control the abutment member 330 to push the locking member 210 into the positioning hole 111b of the positioning assembly 110, thereby achieving a quick vertical lock between the ball head 200 and the ball head seat 100. The operation is simple and intuitive. When the angle of the foot support needs to be adjusted, the operating component 300 can disengage the abutment 330 and the locking component 210 can disengage from the positioning hole 111b. The ball joint 201 can then freely rotate to adjust various required angles. When it is necessary to quickly return to the vertical position, simply push the ball joint 200 back to align the locking component 210 with the positioning hole 111b. At the same time, the operating component 300 pushes the locking component 210 again to fully lock it. The whole process is simple to operate, accurate in positioning, and reliable in locking. It effectively solves the technical problem that the existing camera support foot support cannot quickly return to the vertical position, significantly improving the convenience and work efficiency of the camera equipment. It is especially suitable for camera operation scenarios that require frequent angle adjustments and quick vertical positioning.

[0033] Reference Figure 3 In this embodiment, a ball socket 111a is constructed in the middle of the top plate 111, and a positioning hole 111b is constructed in the center of the bottom wall of the ball socket 111a; the locking member 210 is a positioning pin 211, and a positioning post 213 adapted to the positioning hole 111b is provided at one end of the positioning pin 211.

[0034] In this embodiment, a ball socket 111a is constructed in the middle of the top plate 111. The main function of the ball socket 111a is to provide more stable and precise support and positioning for the ball part 201 of the ball head rod 200. The shape of the ball socket 111a matches the shape of the ball part 201, and can be a standard spherical groove, an ellipsoidal groove, or a spherical groove with a certain taper. The ball socket 111a creates a larger contact area between the ball part 201 and the top plate 111, improving the stability and load-bearing capacity of the support. The positioning hole 111b is constructed at the center of the bottom wall of the ball socket 111a, that is, the axis of the positioning hole 111b coincides with the central axis of the ball socket 111a, ensuring the accuracy of positioning. The positioning hole 111b can be a circular hole, a square hole, or a hole of other geometric shapes, and its size is adapted to the positioning post 213 of the positioning pin 211.

[0035] The locking element 210 is a positioning pin 211, which offers better positioning accuracy and locking reliability compared to traditional pins or locking blocks. The positioning pin 211 can be cylindrical, square, or tapered, and its overall structure includes a positioning post 213 and a pin body. One end of the positioning pin 211 has a positioning post 213 that matches the positioning hole 111b. The diameter or cross-sectional dimensions of the positioning post 213 match the inner diameter of the positioning hole 111b, enabling precise positioning. The positioning post 213 can be cylindrical, tapered, or stepped. A tapered positioning post 213 provides a guiding function, facilitating insertion into the positioning hole 111b; a stepped positioning post 213 provides multi-level positioning, enhancing the locking effect. The other end of the positioning pin 211 contacts the abutment 330 of the operating component 300, facilitating the operating component 300's pushing control.

[0036] In this embodiment, the operating component 300 abuts against the end of the positioning pin 211 opposite to the positioning component 110 via the abutment 330. When the operating component 300 is subjected to external force, the abutment 330 pushes the positioning pin 211, causing its positioning post 213 to extend into the positioning hole 111b at the center of the bottom wall of the ball socket 111a, thereby achieving vertical fixation of the ball head rod 200 relative to the ball head seat 100. The operating component 300 can take the form of a push button, a toggle switch, a rotary knob 113, or a sliding slider, etc., and the abutment 330 can be a push rod, a pin, a pressure plate, etc.

[0037] In the unlocked state, the positioning pin 213 of the positioning pin 211 exits the positioning hole 111b at the center of the bottom wall of the ball socket 111a. At this time, the ball part 201 can rotate and swing in all directions within the ball socket 111a. Due to the constraint of the ball socket 111a, the rotation of the ball part 201 is more stable. At the same time, the ball socket 111a provides good support, and the user can easily make various angle adjustments.

[0038] When a quick return to a vertical position is needed, the user first adjusts the ball part 201 to a position that is basically vertical with the ball head seat 100. At this time, the ball part 201 naturally falls into the ball socket 111a. Due to the good match between the ball socket 111a and the ball part 201, the ball part 201 can be accurately positioned at the center of the ball socket 111a. In this state, under the action of gravity or with the assistance of the elastic element, the positioning pin 211's positioning post 213 can automatically align with the positioning hole 111b at the center of the bottom wall of the ball socket 111a. The user applies external force through the operating component 300, and the abutment component 330 pushes the positioning pin 211 forward, and the positioning post 213 smoothly extends into the positioning hole 111b. Due to the precise fit between the positioning post 213 and the positioning hole 111b, the precise vertical locking of the ball head 200 and the ball head seat 100 is achieved. Throughout the process, the ball socket 111a plays a dual role of guidance and support, ensuring the accuracy of positioning and the reliability of locking.

[0039] When unlocking is required, the user operates the operating component 300 to retract the abutment 330, and the positioning pin 211 retracts under the action of the return mechanism (such as a spring), and the positioning post 213 disengages from the positioning hole 111b. The ball part 201 can then regain the degree of rotational freedom within the ball socket 111a, facilitating the next angle adjustment.

[0040] By constructing a ball socket 111a in the middle of the top plate 111 and setting the positioning hole 111b at the center of the bottom wall of the ball socket 111a, precise positioning and stable support of the ball part 201 are achieved. The cooperation between the ball socket 111a and the ball part 201 provides a larger contact area and better support effect, improving the stability and load-bearing capacity of the overall structure. By using a positioning pin 211 as a locking element 210 and setting a positioning post 213 that matches the positioning hole 111b at one end, precise positioning is achieved. Compared with traditional pins or locking blocks, the positioning pin 211 has better positioning accuracy and locking reliability. The positioning post 213 and the positioning pin 211 are more reliable in locking. The precise fit of the positioning hole 111b ensures the accuracy of vertical locking; the ball socket 111a also serves as a guide, allowing the ball part 201 to be naturally positioned correctly when adjusted to the vertical position, and the positioning pin 213 of the positioning pin 211 can be accurately aligned with the positioning hole 111b, simplifying the operation process; the entire structure is reasonably designed, with accurate positioning, reliable locking, and simple operation, effectively solving the technical problems of inaccurate positioning and unstable locking in the prior art, significantly improving the performance and reliability of the camera bracket foot support device, and is particularly suitable for professional photography applications with high requirements for positioning accuracy and locking stability.

[0041] Continue to refer to Figure 3 In this embodiment, an annular limiting member 203 is fixedly provided in the through hole 202a, and a positioning pin 211 passes through the annular limiting member 203. A limiting protrusion 212 is provided at the end of the positioning pin 211 that abuts against the abutment member 330.

[0042] In this embodiment, an annular limiting member 203 is fixedly provided inside the through hole 202a. The main function of the annular limiting member 203 is to prevent the positioning pin 211 from completely dislodging from the through hole 202a, ensuring that the positioning pin 211 is always kept within the operable range. The annular limiting member 203 can be in the form of an annular boss, an annular retaining ring, an annular washer, etc., and its inner diameter is slightly larger than the pin body diameter of the positioning pin 211, ensuring that the positioning pin 211 can slide freely through.

[0043] The positioning pin 211 passes through the annular limiting member 203, meaning that the positioning pin 211 can reciprocate within the through hole 202a under the constraint of the annular limiting member 203. A limiting protrusion 212 is provided at the end of the positioning pin 211 that abuts against the abutment member 330. The diameter of the limiting protrusion 212 is larger than the inner diameter of the annular limiting member 203. When the positioning pin 211 retracts, the limiting protrusion 212 forms a mechanical limit with the annular limiting member 203, preventing the positioning pin 211 from completely exiting the through hole 202a. The limiting protrusion 212 can be in the form of an annular boss, flange, or locking head, etc.

[0044] When the operating component 300 pushes the positioning pin 211 forward, the positioning post 213 of the positioning pin 211 extends into the positioning hole 111b to lock it; when unlocking is required, the positioning pin 211 retracts backward, but due to the presence of the limiting protrusion 212, the positioning pin 211 can only retract to the position where the limiting protrusion 212 contacts the annular limiting member 203, and cannot completely disengage from the through hole 202a, ensuring that the positioning pin 211 is always in a controllable state and avoiding the problem of the positioning pin 211 being lost or falling off.

[0045] Continue to refer to Figure 3 In this embodiment, a first elastic element 340 and a second elastic element 341 are also provided in the through hole 202a. The first elastic element 340 and the second elastic element 341 are sleeved with the positioning pin 211. The first elastic element 340 is located between the limiting protrusion 212 and the annular limiting element 203, and the second elastic element 341 is located between the positioning post 213 and the annular limiting element 203. The elastic force of the first elastic element 340 is greater than that of the second elastic element 341.

[0046] In this embodiment, a first elastic element 340 and a second elastic element 341 are also provided in the through hole 202a. These two elastic elements are sleeved with the positioning pin 211 to form a double spring reset system. The first elastic element 340 is located between the limiting protrusion 212 and the annular limiting element 203, and the second elastic element 341 is located between the positioning post 213 and the annular limiting element 203. Both elastic elements can be in the form of compression springs, disc springs, or wave springs.

[0047] Under normal conditions, due to the large elastic force of the first elastic element 340, the positioning pin 211 is in the retracted position under the push of the first elastic element 340, the positioning post 213 exits the positioning hole 111b, the system is in the unlocked state, and the ball joint 200 can swing freely to adjust the angle.

[0048] When the ball joint 200 is adjusted to a near-vertical position, the positioning pin 213 of the positioning pin 211 aligns with the positioning hole 111b. At this time, the second elastic element 341 assists the operating component 300 by pushing the positioning pin 211 forward, helping the positioning pin 213 smoothly enter the positioning hole 111b and achieving initial positioning. The second elastic element 341 solves the problem of insufficient gravity or inaccurate alignment, ensuring that the positioning pin 213 can reliably enter the positioning hole 111b.

[0049] Continue to refer to Figure 3 In this embodiment, the positioning component 110 further includes a pusher 112 and a knob 113. The pusher 112 is disposed on the mounting end 100b and is located on the side of the abutment plate 111 facing away from the ball portion 201. The pusher 112 is used to push the abutment plate 111 to move axially along the ball head seat 100. The knob 113 is disposed on the outer wall of the ball head seat 100. The rotating shaft of the knob 113 extends into the ball head seat 100 and abuts against the pusher 112. The knob 113 drives the pusher 112 under the action of external force.

[0050] In this embodiment, the positioning assembly 110 further includes a pusher 112 and a knob 113, used to reliably lock the ball joint 200 with the ball joint seat 100 in the yaw angle state. The pusher 112 is disposed at the mounting end 100b and is located on the side of the abutment plate 111 opposite to the ball part 201. The pusher 112 can be in the form of a push rod, a push block, a push plate, etc. Its main function is to push the abutment plate 111 to move axially along the ball joint seat 100, thereby applying a clamping force to the ball part 201.

[0051] A knob 113 is located on the outer wall of the ball joint 100 for easy user operation. The knob 113 can be circular, polygonal, or have a non-slip texture. The rotating shaft of the knob 113 extends into the ball joint 100 and abuts against the pusher 112. The rotating shaft can be a threaded shaft, cam shaft, or eccentric shaft. When the knob 113 rotates under external force, the rotating shaft drives the pusher 112 to move axially.

[0052] After the ball head 200 is adjusted to the desired yaw angle, the user rotates the knob 113. The rotating shaft of the knob 113 pushes the pusher 112 to move towards the ball part 201. The pusher 112 then pushes the abutment plate 111 to press the ball part 201, forming a friction lock between the ball part 201 and the inner wall of the ball head seat 100, and between the ball part 201 and the abutment plate 111, thereby fixing the ball head 200 at the current yaw angle position.

[0053] When the angle needs to be readjusted, the user rotates the knob 113 in the opposite direction, pushing the pusher 112 and the top plate 111 backward, releasing the clamping force on the ball part 201, and the ball part 201 regains its rotational freedom, allowing for a new angle adjustment.

[0054] See Figures 1 to 3 In this embodiment, the abutting member 330 is a guide rod 331 and an abutting rod 332; the operating component 300 also includes a first foot pedal 310, one end of which is constructed with a first strip plate 311, and the first strip plate 311 is provided with a first connecting hole 311a and a second connecting hole 311b at intervals, one end of the abutting rod 332 is connected to the first connecting hole 311a, and one end of the guide rod 331 is connected to the second connecting hole 311b; The connecting section 202 is provided with a strip hole 202b and a limiting hole 202c. The strip hole 202b extends along the axial direction of the connecting section 202, and the limiting hole 202c extends along the circumferential direction of the connecting section 202 and is connected to one end of the strip hole 202b. The other end of the abutment rod 332 extends into the limiting hole 202c and can move along the extension direction of the limiting hole 202c. The other end of the guide rod 331 extends into the strip hole 202b and can move along the extension direction of the strip hole 202b.

[0055] In this embodiment, the abutment member 330 includes two components: a guide rod 331 and an abutment rod 332, achieving more stable and precise operation control. The operation component 300 also includes a first foot pedal 310, one end of which is constructed with a first strip plate 311. The first strip plate 311 is provided with a first connecting hole 311a and a second connecting hole 311b spaced apart. One end of the abutment rod 332 is connected to the first connecting hole 311a, and one end of the guide rod 331 is connected to the second connecting hole 311b, forming an integral operation unit.

[0056] The connecting section 202 is constructed with a strip-shaped hole 202b and a limiting hole 202c. The strip-shaped hole 202b extends axially along the connecting section 202, providing a normal movement channel for the abutment rod 332 and the guide rod 331. The limiting hole 202c extends circumferentially along the connecting section 202 and communicates with one end of the strip-shaped hole 202b, forming an L-shaped or T-shaped composite hole structure. The other end of the abutment rod 332 extends into the limiting hole 202c and can move along the extension direction of the limiting hole 202c. The other end of the guide rod 331 extends into the strip-shaped hole 202b and can move along the extension direction of the strip-shaped hole 202b, serving a guiding and stabilizing function.

[0057] During the locking operation, the user can step on the first foot pedal 310, at which time the abutment rod 332 and guide rod 331 move downward in the strip hole 202b. As the foot pedal is pressed down, the abutment rod 332 pushes the locking member 210, causing the locking member 210 to extend from the through hole 202a and into the limiting hole 202c, thus achieving initial locking.

[0058] As pressure is applied continuously, the abutment rod 332 slides from one end of the slotted hole 202b into the limiting hole 202c. Since the limiting hole 202c and the slotted hole 202b are perpendicularly positioned at 90 degrees, a mechanical locking state is achieved when the abutment rod 332 enters the limiting hole 202c. When the user releases the downward pressure, the abutment rod 332, under the action of the first elastic element 340, will remain stably within the limiting hole 202c and will not automatically return to the slotted hole 202b, achieving stable vertical locking. This prevents accidental locking due to accidental contact or vibration.

[0059] During unlocking, the user needs to apply an upward pushing force to the first foot pedal 310 to overcome the elastic force of the first elastic element 340, causing the abutment rod 332 to disengage from the limiting hole 202c and re-enter the slotted hole 202b. Once the abutment rod 332 returns to the slotted hole 202b, under the elastic action of the first elastic element 340, the abutment rod 332 and the guide rod 331 move upward within the slotted hole 202b, while the locking element 210 disengages from the limiting hole 202c, and the ball joint 200 returns to its free swing state.

[0060] This technical solution achieves both locking and unlocking functions with a single foot pedal, making operation simple and intuitive. The vertical arrangement of the strip hole 202b and the limiting hole 202c forms a reliable mechanical locking mechanism, ensuring the stability of the locked state. The guide rod 331 improves the stability and accuracy of operation and avoids jamming. The foot pedal operation frees the user's hands, making it particularly suitable for the rapid operation needs in photography, significantly improving ease of use and work efficiency.

[0061] See Figure 4 , Figure 5 , Figure 6 and Figure 7 In this embodiment, the operation component 300 further includes: The first foot pedal 310 includes a first support arm 312 and a first strip plate 311 constructed at one end of the first support arm 312. One end of the first strip plate 311 is hinged to the end of the connecting section 202 away from the ball head. The second foot pedal 320 includes a second support arm 322 and a second strip plate 323 constructed at one end of the second support arm 322. One end of the second strip plate 323 is hinged to the other end of the first strip plate 311. A strip hole 202b is constructed on the side wall of the connecting section 202. The abutment 330 is a guide rod 331, which passes through the strip hole 202b and is connected to the other end of the second strip plate 323.

[0062] In the overall structure, the first foot pedal 310 and the second foot pedal 320 are arranged in an L-shape. The second support arm 322 is longer than the first support arm 312 to ensure that they do not interfere with each other during operation, while providing a better operating leverage ratio.

[0063] The locking operation is achieved by pressing down the second foot pedal 320. When the user presses down the second foot pedal 320, the second support arm 322 moves toward the ball joint 100, causing the second strip plate 323 to move. Since the second strip plate 323 is hinged to the first strip plate 311, the end of the second strip plate 323 that is hinged to the first strip plate 311 moves away from the connecting section 202, while the other end of the second strip plate 323 drives the guide rod 331 to move downward in the strip hole 202b, pushing the locking member 210 into the positioning hole 111b.

[0064] During this process, the other end of the first strip plate 311 is also driven by the transmission mechanism to move away from the connecting section 202. When the user releases the pressure of the second foot pedal 320, the key lever locking mechanism begins to function: the first strip plate 311 and the second strip plate 323, under the elastic support of the first elastic member 340, form a lever tendency to resist each other. This resisting force maintains the pushing force of the guide rod 331 on the locking member 210, so that the locking member 210 is stably kept in the positioning hole 111b.

[0065] In the locked state, the second arm 322 is located below, and the first arm 312 is located above the second arm 322 under the transmission action of the second strip plate 323 and the first strip plate 311, which facilitates the user to perform subsequent unlocking operations.

[0066] The unlocking operation is very convenient; the user only needs to step on the first foot pedal 310 to break the lever's blocking state. Specifically, when the first foot pedal 310 is stepped on and pressed down, the first arm 312 moves the other end of the first strip plate 311 toward the connecting section 202, and at the same time moves the second strip plate 323 toward the connecting section 202, thus breaking the blocking tendency between the first strip plate 311 and the second strip plate 323.

[0067] Once the resistance is lost, the force of the first elastic element 340 causes the locking element 210 to disengage from the positioning hole 111b, the guide rod 331 returns to its original position, the system returns to the unlocked state, and the ball joint 200 can swing freely for adjustment.

[0068] This dual-foot lever locking system achieves a self-holding function in the locked state through the lever principle, maintaining the locked state without continuous force. The dual-foot design allows for separate locking and unlocking operations, avoiding accidental operation. The longer design of the second support arm 322 provides a better operating leverage ratio, reducing the operating force. The unlocking operation is simple and direct; simply stepping lightly on the first foot pedal 310 is sufficient for quick unlocking. The entire system has a reasonable structure, is convenient to operate, and has reliable locking, making it particularly suitable for professional photography applications that require frequent locking and unlocking operations.

[0069] Please refer to Figure 8 and Figure 9 In some embodiments, the abutment 330 includes a pressing part 333 and a driving part 334 connected to each other. The connecting section 202 is constructed with a strip hole 202b that extends through its interior and exterior. One end of the driving part 334 extends into the connecting section 202 through the strip hole 202b, and the driving part 334 can abut against the locking member 210. The pressing part 333 is exposed outside the connecting section 202 and is used to push the driving part 334 to drive the locking member 210 to move under the action of external force.

[0070] In this embodiment, the pressing part 333 and the driving part 334 of the abutment 330 and the strip hole 202b of the connecting section 202 form a precise force transmission and motion constraint system. Specifically, the strip hole 202b of the connecting section 202 provides a sliding path for the driving part 334, and its length direction is consistent with the axis of the through hole 202a through which the locking part 210 moves, avoiding the driving part 334 from deviating and getting stuck, and ensuring locking stability; the pressing part 333, due to its larger surface area, can efficiently convert and transmit the user's pressing force to the driving part 334, and then the driving part 334 pushes the locking part 210 to move along the through hole 202a, realizing an instant response of pressing and locking; at the same time, the gap fit between the strip hole 202b and the driving part 334 can maintain the position of the driving part 334 when locked, and combined with the elastic element in the through hole 202a, the locking part 210 and the driving part 334 can be pushed to reset after the external force is removed, forming a complete cycle of pressing to lock and releasing force to reset.

[0071] The pressing part 333 is exposed and often designed with an arc shape, a raised shape, or a non-slip texture. Users can quickly lock the device vertically without needing a specific angle or tools, simply by using their feet or other methods. This is more efficient than traditional knobs or levers and is suitable for scenarios such as wedding photography and sporting events where frequent switching between vertical positions is required. The movement of the drive part 334 is limited by the length of the slot 202b. Users can adjust the depth of the locking part 210 into the positioning hole 213 by controlling the pressing stroke, achieving flexible switching between initial positioning and complete locking, and avoiding damage to the parts due to excessive force. In addition, the size of the slot 202b can be adjusted with the drive part 334, and the shape of the pressing part 333 can also adapt to the appearance and grip habits of the connecting section 202, making it widely applicable to different models of photography brackets and enhancing its versatility.

[0072] In some embodiments, the driving part 334 is provided with a limiting groove 335 on the side facing the locking member 210, and the locking member 210 is provided with a limiting protrusion 212 at the position corresponding to the limiting groove 335. The limiting protrusion 212 can engage with the limiting groove 335 to limit the relative displacement of the abutment 330 and the locking member 210.

[0073] In this embodiment, a limiting groove 335 is provided on the side of the driving part 334 facing the locking member 210, and a limiting protrusion 212 is provided at the corresponding position on the locking member 210. The locking and engaging structure formed by the two further improves the force transmission and motion constraint mechanism between the abutment member 330 and the locking member 210. When the operating component 300 pushes the abutment member 330 to move, the driving part 334 moves closer to the locking member 210. As the two come into contact, the limiting protrusion 212 of the locking member 210 gradually embeds into the limiting groove 335 of the driving part 334, forming a physical locking. This locking structure restricts the relative displacement of the abutment 330 and the locking member 210 in the direction perpendicular to the movement, preventing misalignment of the drive unit 334 and the locking member 210 due to vibration, external impact, or long-term use. It ensures that the force of the drive unit 334 is always accurately applied to the axial direction of the locking member 210, allowing the locking member 210 to move stably along the through hole 202a without jamming or misalignment with the positioning hole 213 due to relative offset. Together with the guiding effect of the strip hole 202b, it forms a double guarantee, improving the movement accuracy of the entire locking system.

[0074] The locking mechanism between the limiting protrusion 212 and the limiting groove 335 prevents the abutment 330 and the locking member 210 from sliding laterally under force. This is especially important in outdoor shooting conditions such as wind and ground vibrations, preventing the locking state from loosening due to relative displacement. It ensures that the locking member 210 remains within the positioning hole, maintaining the vertical stability of the foot support device and ensuring the safety of the photographic equipment. In terms of operational reliability, when the limiting protrusion 212 is inserted into the limiting groove 335, a slight locking sensation is generated, providing additional tactile feedback to the user. This allows the user to clearly perceive that the abutment 330 and the locking member 210 are precisely aligned, preventing uneven force transmission due to misalignment. This ensures that subsequent pressing operations can efficiently push the locking member 210 to lock, reducing operational errors, making it particularly suitable for use in low-light or obstructed shooting scenarios.

[0075] This utility model further proposes a photographic support frame, including a telescopic tube assembly and a foot support device as described in the foregoing embodiments. The specific structure of the foot support device is as described in the above embodiments. Since this photographic support frame adopts all the technical solutions of all the above embodiments, it has at least all the technical effects brought about by the technical solutions of the above embodiments, and will not be described in detail here.

[0076] The telescopic tube assembly comprises multiple telescopic tube sections connected by a locking mechanism, allowing the height of the support frame to be adjusted according to shooting needs. The top of the telescopic tube assembly has a mounting interface for photographic equipment such as cameras and camcorders, while the bottom connects to the connecting section 202 of the foot support device.

[0077] The foot support device is connected to the bottom end of the telescopic tube assembly via the connecting section 202 of the ball joint 200, providing stable ground support for the entire camera support frame. When angle shooting is required, multi-angle adjustment can be achieved through the cooperation of the ball joint 100 and the ball joint 200; when a quick return to a vertical position is required, quick vertical locking can be achieved through the cooperation of the positioning pin 211 and the positioning hole 111b; through the setting of various operating components 300 (foot pedal, knob 113, etc.), users can easily perform locking and unlocking operations.

[0078] This photography support frame has a compact structure and is easy to operate. It can meet the needs of multi-angle shooting and achieve rapid vertical positioning, which significantly improves the efficiency and convenience of photography operations. It is especially suitable for application scenarios that require frequent adjustment of the support angle, such as outdoor photography, sports event shooting, and news interviews.

[0079] The above description is only a part or preferred embodiment of this utility model. Neither the text nor the drawings should limit the scope of protection of this utility model. All equivalent structural transformations made using the content of this utility model specification and drawings under the overall concept of this utility model, or direct / indirect applications in other related technical fields, are included within the scope of protection of this utility model.
