Detailed Implementation

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0033] To achieve the above objectives, the technical solution of this utility model is as follows:

[0034] See Figure 1-11 This embodiment provides a conveniently foldable extension device that can be applied to mobile workstations, wherein the mobile workstation can be a director's vehicle commonly used in the field of photography.

[0035] Specifically, see Figure 1-2 The foldable extension device of this embodiment includes:

[0036] Expand Platform 1;

[0037] The folding mechanism 5 includes a connector 51, a support 52, and a locking assembly 53. One end of the connector 51 is provided with a mounting piece 2 that can be connected to the mobile workstation, and the other end is movably connected to the expansion platform 1. One end of the support 52 is movably connected to the connector 51, and the other end is connected to the expansion platform 1 through the locking assembly 53, so that the expansion platform 1 can be folded relative to the mounting piece 2.

[0038] When in use, the connector 51 and the support 52 can drive the expansion platform 1 to rotate, thereby folding or unfolding the expansion platform 1. When in use, the expansion platform 1 is unfolded and supported by the support 52. When not in use, the expansion platform 1 can be folded and stored on one side of the director's vehicle by rotating, thus saving space.

[0039] Specifically, mounting component 2 can use common clamps on the market, such as pipe clamps, which can be clamped and fixed on the column of the director vehicle, thus facilitating the assembly and disassembly of the foldable extension device.

[0040] Specifically, both the connector 51 and the support 52 are rod-shaped structures. The connector 51 has rotating shafts at both ends, and a rotating seat is located at the bottom of the expansion platform 1. The expansion platform 1 is rotatably connected to the rotating shaft at one end of the connector 51 via the rotating seat. The support 52 has rotating ends at both ends. One end of the support 52 is rotatably connected to the other rotating shaft of the connector 51 via the rotating end, and the other end is rotatably connected to the locking assembly 53 via the rotating end. The locking assembly 53 is slidably connected to the expansion platform 1. With this structure, during normal use, the locking assembly 53 can lock onto the expansion platform 1 and provide support via the support 52, ensuring stable operation. When storage is required, the sliding of the locking assembly 53 relative to the expansion platform 1 causes the expansion platform 1 to move relative to the connector 51 and the support 52, allowing the expansion platform 1 to fold and be stored closer to the mounting piece 2 and the director's carriage.

[0041] Further, see Figure 3-11 The locking assembly 53 includes a main body 531, a sliding member 532, and a locking member 530. The end of the support member 52 near the expansion platform 1 is movably connected to the main body 531. The sliding member 532 is fixedly connected to the main body 531. The expansion platform 1 is provided with a slide groove 11, and the sliding member 532 is slidably connected in the slide groove 11. The expansion platform 1 has a pressing part 13. A pressing position 54 for clamping the pressing part 13 is provided between the locking member 530 and the sliding member 532. The locking member 530 is movably installed on the main body 531 to adjust the size of the pressing position 54 so that the pressing position 54 can clamp or release the pressing part 13. When clamped, the sliding member 532 and the expansion platform 1 can be locked, so that when the expansion platform 1 is unfolded, the sliding member 532 cannot slide, and the structure is stable. When released, the sliding member 532 can slide relative to the expansion platform 1, which can be easily folded or unfolded.

[0042] Specifically, a rotating shaft is provided at the bottom of the main body 531, and the rotating end of the support member 52 away from the connecting member 51 is rotatably connected to the rotating shaft at the bottom of the main body 531. The sliding member 532 adopts a dovetail-shaped slider, and the slide groove 11 adopts a dovetail groove, so that the sliding member 532 can be stably held in the slide groove 11 and can slide within the slide groove 11. When the extension platform 1 is unfolded for use, the anti-detachment member 533 is inserted into the anti-detachment hole 12 of the extension platform 1, thereby fixing the main body 531 and the sliding member 532 relative to the extension platform 1 and achieving stable support.

[0043] Furthermore, the locking member 530 includes a locking handle 535, a connecting rod 536, and a locking block 537. The locking handle 535 and the connecting rod 536 are movably mounted on the main body 531 and can rotate horizontally relative to the main body 531. A first movable position 5322 is provided in the sliding member 532. The locking block 537 is movably disposed in the first movable position 5322. One end of the connecting rod 536 is fixedly connected to the locking handle 535, and the other end is threadedly connected to the locking block 537. The locking block 537 has a first clamping surface 5371. The inner wall of the first movable position 5322 has a second clamping surface 5323. A pressing position 54 is formed between the first clamping surface 5371 and the second clamping surface 5323. The pressing part 13 is disposed on the pressing position 54. In use, by rotating the locking handle 535, the connecting rod 536 is driven to rotate horizontally relative to the locking block 537. Since the connecting rod 536 is fixed in the vertical direction of the main body 531, it will drive the locking block 537 to move toward the side of the sliding member 532 through the threaded connection, tightening the pressing position 54, so that the pressing position 54 clamps the pressing part 13, thereby locking the sliding member 532 and the expansion platform 1. Conversely, when the locking handle 535 is rotated in the opposite direction, the locking block 537 can be driven to move toward the side of the expansion platform 1, expanding the pressing position 54, so that the pressing position 54 releases the pressing part 13, thereby unlocking the sliding member 532 and the expansion platform 1.

[0044] Furthermore, the locking handle 535 includes a toggle part 5352, a first rotating part 5354, and a trigger part 5353. The main body 531 is provided with a second movable position 5312. The toggle part 5352 is movably disposed in the second movable position 5312 and can rotate horizontally in the second movable position 5312. The toggle part 5352 is fixedly connected to the first rotating part 5354 and protrudes out of the main body 531. The connecting rod 536 includes a second rotating part 5361. The first rotating part 5354 and the second rotating part 5361 are fixedly connected by gear meshing. The main body 531 is provided with a limiting groove 5311. The bottom of the second rotating part 5361 is movably disposed on the limiting groove 5311, and the upper part of the second rotating part 5361 is limited by the bottom of the sliding member 532, so that the second rotating part 5361 can rotate horizontally within the limiting groove 5311 under the drive of the locking handle 535, and can also make small up-and-down movements within the limiting groove 5311. The connecting rod 536 also includes a threaded connection part 5362, which is fixedly connected to the second rotating part 5361. The locking block 537 has a screw hole 5372, and the threaded connection part 5362 is threadedly connected to the screw hole 5372. The threaded connection part 5362 is a threaded shaft. When the actuating part 5352 is rotated, the locking block 537 and the threaded shaft can move relative to each other in the axial direction, thereby moving the locking block 537 in the axial direction and adjusting the size of the pressing position 54.

[0045] Furthermore, the locking assembly 53 also includes an anti-detachment member 533. An anti-detachment hole 12 is provided on the expansion platform 1. The anti-detachment member 533 is elastically disposed on the main body 531. The trigger part 5353 has a first pressing slope 5351. The anti-detachment member 533 includes a second pressing slope 5331 adapted to the first pressing slope 5351. The first pressing slope 5351 can move against the second pressing slope 5331, allowing the locking handle 535 to push the anti-detachment member 533 away from the anti-detachment hole 12. The locking assembly 53 includes a first elastic member 534. A third movable position 5313 is provided on the main body 531. The anti-detachment member 533 is movably disposed within the third movable position 5313. One end of the first elastic member 534 abuts against or connects to the inner wall of the third movable position 5313, and the other end abuts against or connects to the end of the anti-detachment member 533 away from the anti-detachment hole 12. Under normal circumstances, when the expansion platform 1 is in the unfolded or folded state, the first elastic member 534 can use its elasticity to push the end of the anti-detachment member 533 into the anti-detachment hole 12 to achieve positioning and locking. When it is necessary to change the state of the expansion platform 1, such as opening for use or folding for storage, the locking handle 535 is turned to unlock. At this time, not only will the locking block 537 move to release the pressing part 13, but the trigger part 5353 will also move toward the anti-detachment member 533. It can press the second pressing inclined surface 5331 to move through the first pressing inclined surface 5351, thereby pushing the anti-detachment member 533 out of the anti-detachment hole 12, releasing the positioning, and the sliding member 532 can slide smoothly in the sliding groove 11, thereby facilitating the folding or unfolding of the expansion platform 1.

[0046] Furthermore, the anti-detachment component 533 includes a supporting part 5332 and a positioning part 5333. The supporting part 5332 and the positioning part 5333 are fixedly connected. The supporting part 5332 is movably disposed in the third movable position 5313. The sliding part 532 is provided with a through hole 5321. One end of the positioning part 5333 movably passes through the through hole 5321 and is movably connected to the anti-detachment hole 12. The second pressing inclined surface 5331 is located on the outer wall of the supporting part 5332, and the other end of the first elastic member 534 abuts or connects with the bottom wall of the supporting part 5332. Through the above structural design, when the toggle part 5352 is rotated outside the main body 531, the trigger part 5353 can push the support part 5332 to move, thereby driving the positioning part 5333 to move up and down in the third movable position 5313, so that the positioning part 5333 disengages from the anti-disengagement hole 12, realizing the unlocking between the anti-disengagement member 533 and the expansion platform 1. At this time, the anti-disengagement member 533 will compress the first elastic member 534. Similarly, when the anti-disengagement member 533 and the expansion platform 1 are in the unlocked state, rotating the toggle part 5352 in the opposite direction can drive the trigger part 5353 to disengage from the support part 5332. Without the pressure of the trigger part 5353, the anti-disengagement member 533 can be reset under the elastic action of the first elastic member 534.

[0047] Furthermore, both the first pressing inclined surface 5351 and the second pressing inclined surface 5331 are inclined surfaces with the same slope. By cooperating through the inclined surface structure, the first pressing inclined surface 5351 and the second pressing inclined surface 5331 can be in contact with each other while also being able to push the second pressing inclined surface 5331 to move.

[0048] Furthermore, the anti-detachment hole 12 includes a first anti-detachment hole 121, which is opened in the middle of the slide groove 11 to achieve positioning when the expansion platform 1 is unfolded.

[0049] Furthermore, the anti-detachment hole 12 includes a second anti-detachment hole 122, which is opened at the end of the slide groove 11 to achieve positioning when the extension platform 1 is folded and stored.

[0050] Furthermore, a second elastic element 538 is also provided within the first movable position 5322. One end of the second elastic element 538 abuts against or connects to the inner wall of the first movable position 5322, and the other end abuts against or connects to the side of the locking block 537 away from the slide groove 11. The second elastic element 538 can push the side of the locking block 537 facing the expansion platform 1 into the slide groove 11, contacting the bottom wall of the slide groove 11, which can prevent any misalignment within the slide groove 11 and improve the stability of the structure.

[0051] Specifically, both the first elastic element 534 and the second elastic element 538 are standard parts with elastic functions, such as springs.

[0052] Furthermore, the expansion platform 1 has an IGT module 3. The expansion platform 1 can be installed on the director vehicle via the mounting component 2. The IGT module 3 on the expansion platform 1 can enrich the functions of the director vehicle, thereby solving the problem of the director vehicle having limited functionality.

[0053] Furthermore, the expansion platform 1 has one or more expansion slots 4. The expansion slots 4 can adopt standard expansion interfaces such as expansion slots 41 and expansion holes 42, and can install IGT modules 3 with different functions, such as IGT tabletops 31, IGT hooks, outdoor stoves, cutting boards, storage racks, refrigerators or freezers, etc.

[0054] Specifically, the expansion platform 1 is composed of several panels joined together, with expansion grooves 41 formed between the panels for installing the IGT tabletop 31; expansion holes 42 are provided on the panels for installing IGT hooks.

[0055] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
