[0037] Reference Figures 1 to 6 A hydraulic photographic stand capable of reducing space occupancy includes a support base 100 and a plurality of telescopic legs 200 rotatably connected to the support base 100, each telescopic leg 200 being provided with a group of hydraulic locking assemblies 300, a pan / tilt assembly for connecting photographic equipment being provided on the support base 100, and also including a hydraulic control handle 400, the hydraulic control handle 400 being installed on any telescopic leg 200 and being connected to a plurality of hydraulic locking assemblies 300, the hydraulic control handle 400 being used to unlock or lock the hydraulic locking assemblies 300, and the hydraulic control handle 400 being able to rotate outwardly to expand or rotate inwardly to fold simultaneously with the telescopic leg 200.
[0038] 1. Reference Figure 1 and 5 In the present invention, the support seat 100 is preferably a three-cut seat, and the telescopic legs 200 are set to 3. The telescopic legs 200 have multiple telescopic tubes, and a primary telescopic structure is formed between two adjacent telescopic tubes and is unlocked or locked by a hydraulic locking assembly 300. It should be noted that the hydraulic locking assembly 300 can adopt a locking assembly in the prior art, such as Chinese invention patent ---- Support leg assembly and telescopic bracket (application number 2024114946614), etc., which will not be repeated here; when in use, the photographic equipment is installed on the support seat 100. When the photographic bracket needs to be unfolded, the three telescopic legs 200 are first rotated outward to open to the required angle. Since the hydraulic control handle 400 is installed on the telescopic leg 200, it will be unfolded synchronously when the telescopic leg 200 is unfolded. At this time, the hydraulic control handle 400 is operated to control the three telescopic legs 200. The hydraulic locking assembly 300 is unlocked to unfold the multiple telescopic tubes on the telescopic legs 200 to meet the height requirement during shooting; after unfolding to the required height, the hydraulic control handle 400 is operated again to control the hydraulic locking assemblies 300 on the three telescopic legs 200 to lock, so as to fix the unfolded state; when it is necessary to fold the photographic support, the hydraulic control handle 400 is first operated to control the hydraulic locking assemblies 300 on the three telescopic legs 200 to unlock, and then the multiple telescopic tubes on the telescopic legs 200 are folded. After they are completely folded, the hydraulic control handle 400 is operated again to control the hydraulic locking assemblies 300 on the three telescopic legs 200 to lock, so as to fix the folded state, and finally the multiple telescopic legs 200 are rotated inwards to fold. Since the hydraulic control handle 400 is installed on the telescopic legs 200, it will be folded synchronously when the telescopic legs 200 are folded.
[0039] 2. Reference Figure 1-Figure 4 In some embodiments, the hydraulic control handle 400 includes a seat body 410, a first plunger 420, a liquid guide tube 430 and a trigger 440; the seat body 410 is mounted on any telescopic leg 200 and is provided with a liquid storage chamber 411 and a liquid outlet 412 connected to the liquid storage chamber 411, and the liquid storage chamber 411 is filled with hydraulic medium; the first plunger 420 is disposed in the liquid storage chamber 411; one end of the liquid guide tube 430 is connected to the liquid outlet 412, and the other end is connected to the hydraulic locking assembly 3 00 is connected; the trigger 440 is rotatably connected to the seat body 410 and has a first position and a second position that can be switched to each other; when the trigger 440 is switched from the first position to the second position, the first plunger 420 is pushed to slide in the liquid storage chamber 411, so that the hydraulic medium is squeezed into the guide tube 430 through the liquid outlet 412; or when the trigger 440 is switched from the second position to the first position, the force on the first plunger 420 is cancelled, so that the hydraulic medium flows back to the liquid storage chamber 411 through the liquid outlet 412.
[0040] The example of the hydraulic control handle 400 controlling the hydraulic locking assembly 300 to unlock is used for explanation. Specifically, in the initial state, the trigger 440 is away from the telescopic foot 200 and is in the first position. When the trigger 440 is operated to switch from the first position to the second position (i.e., the trigger 440 moves toward the telescopic foot 200), the trigger 440 will push the first plunger 420 to slide in the liquid storage chamber 411, thereby squeezing the hydraulic medium in the liquid storage chamber 411 to overflow through the liquid outlet 412 and enter the liquid guide tube 430, and the hydraulic locking assembly 300 is hydraulically unlocked along the liquid guide tube 430; when the telescopic foot 200 is deployed in place, the trigger 440 is released, the first plunger 420 loses external power and resets under the pressure of the hydraulic medium. Of course, in order to ensure the stability of the reset of the first plunger 420, a fifth elastic member 450 can be set in the liquid storage chamber 411 to provide reset power. At this time, the trigger 440 is switched from the second position to the first position again.
[0041] 3. Reference Figure 1-Figure 4 In some embodiments, the trigger 440 is connected to the base 410 through a clutch structure 500, so that the trigger 440 has an operating state and a retracted state. When the trigger 440 is in the operating state, it can switch between the first position and the second position. When the trigger 440 is in the retracted state, it is close to or in contact with the telescopic foot 200; as a preferred embodiment of the clutch structure 500, the clutch structure 500 includes a clutch block 510, a top block 520, a first elastic member 530 and a second elastic member 540; the clutch block 510 is movably arranged on the trigger 440 and has a third position and a fourth position, and a clearance groove 511 is arranged on the clutch block 510; The top block 520 is movably arranged on the trigger 440 and abuts against the first plunger 420; the first elastic member 530 abuts against the clutch block 510 and the trigger 440 respectively, and is used to drive the clutch block 510 to switch from the fourth position to the third position; the second elastic member 540 abuts against the top block 520 and the trigger 440 respectively, and is used to drive the top block 520 to reset; the top block 520 can abut against the outer wall of the clutch block 510 when the clutch block 510 is in the third position, so that the trigger 440 enters the operating state; or the top block 520 can extend into the avoidance groove 511 when the clutch block 510 is in the fourth position, so that the trigger 440 enters the retracted state.
[0042] Specifically, taking the trigger 440 switching from the operating state to the retracted state as an example, when the trigger 440 is in the operating state, the clutch block 510 is in the third position, and the top block 520 is in contact with the outer wall of the clutch block 510. When the trigger 440 is pressed, the clutch block 510 will be driven to drive the top block 520 to move toward the first plunger 420, thereby causing the hydraulic medium in the liquid storage chamber 411 to overflow through the liquid outlet 412 and enter the liquid guide tube 430, and then flow along the liquid guide tube. 430 is used to hydraulically unlock the hydraulic locking assembly 300; when the photographic support needs to be folded, the clutch block 510 is first pressed to switch the clutch block 510 from the third position to the fourth position, so that the top block 520 will enter the escape groove 511 on the clutch block 510. At this time, when the trigger 440 is pressed again, the depth of the top block 520 extending into the escape groove 511 will increase, and the second elastic member 540 will be compressed until the trigger 440 is close to or in contact with the telescopic foot 200 ( Figure 4 ), the outward opening angle of the trigger 440 can be reduced, that is, the space occupied by the photographic support when it is folded can be further reduced; it should be noted that when the trigger 440 enters the folded state, external force is required to overcome the friction between the components and the elastic force of the second elastic member 540, and the second elastic member 540 can drive the top block 520 to reset when the trigger 440 enters the operating state, that is, drive the top block 520 to disengage from the air avoidance groove 511, so that the clutch block 510 can enter the third position from the fourth position under the drive of the first elastic member 530.
[0043] 4. Reference Figure 1-Figure 4 In some embodiments, a hydraulic photographic stand that can reduce space occupancy also includes a power-assisting structure 600 connected between a base body 410 and a trigger 440. As a preferred embodiment of the power-assisting structure 600, the power-assisting structure 600 includes a third elastic member 610 and a push block 620. A mounting groove 630 is provided on the base body 410. One end of the third elastic member 610 abuts against the mounting groove 630, and the other end of the third elastic member 610 is connected to one end of the push block 620. The other end of the push block 620 abuts against the trigger 440. The elastic force of the third elastic member 610 is greater than the elastic force of the second elastic member 540. The power-assisting structure 600 can not only provide power assistance when the trigger 440 is switched from an operating state to a retracted state, but also enable the trigger 440 to maintain a retracted state to prevent the trigger 440 from retreating to the operating state.
[0044] 5. Reference Figure 1-Figure 4In some embodiments, a waist-shaped groove 521 extending along the elastic force direction of the second elastic member 540 is provided on the top block 520, and a limiting portion 522 extending into the waist-shaped groove 521 is provided on the trigger 440; the top block 520 is limited by the cooperation between the waist-shaped groove 521 and the limiting portion 522, which can prevent the top block 520 from detaching from the groove on the trigger 440 and limit the movement range of the top block 520.
[0045] 6. Reference Figure 1-Figure 4 In some embodiments, a pressure relief chamber 720 connected to the liquid storage chamber 411 through the pressure relief hole 710 is provided on the seat body 410, and also includes a fourth elastic member 730 and a second plunger 740 arranged in the pressure relief chamber 720, one end of the fourth elastic member 730 abuts against the side of the second plunger 740 facing away from the pressure relief hole 710, and the other end abuts against the pressure relief chamber 720; since the user may use excessive force when operating the trigger 440, causing excessive pressure on the components, thereby causing certain damage to the components, this setting can allow the hydraulic medium to enter the pressure relief chamber 720 through the pressure relief hole 710 when the pressure is too high, and be absorbed by the fourth elastic member 730, thereby avoiding excessive pressure in the liquid storage chamber 411 and the liquid guide tube 430.
[0046] In a further embodiment, a hydraulic photographic stand that can reduce space occupancy also includes a threaded plug 750 connected to the base body 410 and closing the pressure relief chamber 720, and the other end of the fourth elastic member 730 abuts against the threaded plug 750; the threaded plug 750 is used to limit the fourth elastic member 730 and the second plunger 740, and the pressure relief chamber 720 can be further closed in conjunction with an outer cover and bolts.
[0047] 7. Reference Figure 5-Figure 6 In some embodiments, a wiring groove 110 is provided on the support seat 100, and a wiring groove 110 is provided with a wiring inlet 120 and a plurality of wiring outlets arranged opposite to the telescopic foot 200. The liquid guide tube 430 is passed through the wiring inlet 120, the wiring groove 110 and the wiring outlet and is connected to the hydraulic locking assembly 300. This configuration constructs a space for wiring of a plurality of liquid guide tubes 430, and the number of the liquid guide tubes 430 is adapted to the telescopic foot 200. In the embodiment where the number is set to 3, the line inlet 120 is set to 1 and the line outlet is set to 2, wherein the line inlet 120 is arranged opposite to the telescopic foot 200 connected to the hydraulic control handle 400, and two liquid guide tubes 430 enter the wiring groove 110 through the line inlet 120, and then extend from one of the line outlets respectively until they are respectively connected to the hydraulic locking assemblies 300 on the other two telescopic feet 200; further, a cover plate 800 is provided to close the wiring groove 110.
[0048] 8. The advantage of the present invention is that: through the above structure, the hydraulic control handle can be synchronously expanded or folded along with the telescopic legs, which not only reduces the space occupied by the hydraulic photographic stand in the folded state, but also improves the convenience of using the hydraulic photographic stand and meets the use requirements.
