Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a dedicated mobile worktable for placing radio frequency coils. Background Technology

[0002] A dedicated mobile workbench for RF coils provides a stable platform for placing RF coils of various sizes, ensuring that the coils do not wobble or slip during movement. This allows the coils to be safely stored when not in use, avoiding collisions, damage, or dust contamination. Existing coil cabinets are large and heavy, resulting in limited storage space and making them unsuitable for movement. When retrieving and placing RF coils, staff often have to walk long distances, which wastes time and increases unnecessary movement.

[0003] In the existing technology, some dedicated mobile worktables for placing radio frequency coils cannot provide support against the ground after the coil cabinet is moved during actual use. This causes the coil cabinet to shift on its own, which can damage the coil and the equipment. Therefore, in order to address the above-mentioned problems, a dedicated mobile worktable for placing radio frequency coils is proposed. Utility Model Content

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1 to 2As shown, this utility model provides an embodiment of a dedicated mobile workbench for placing radio frequency (RF) coils, including a placement platform 1. The placement platform 1, as the core component of the entire device, has a flat surface, providing a stable placement space for the RF coils. A baffle 2, 3cm high, is fixedly connected to the top of the placement platform 1 to prevent the coils placed on it from slipping. Two placement slots 3 are provided inside the placement platform 1, each 40cm high, 60cm wide, and 120cm long, capable of accommodating RF coils of different sizes, ensuring a height higher than all RF coils currently on the market. A base plate 4 is fixedly connected to the bottom of the placement platform 1, providing a height of approximately 85cm, similar to the height of an imaging equipment workbench, ensuring comfortable operation for the operator. Universal casters 5 are fixedly connected to the four corners of the bottom of the base plate 4, allowing for flexible rotation and easy movement of the entire workbench. A support assembly for pushing is fixedly connected to the bottom of the base plate 4, including two mounting blocks 11. The mounting blocks 11 are firmly connected, providing stable support for the connecting rod 6.

[0032] Reference Figures 1 to 2 As shown, the top of the mounting block 11 is fixedly connected to the bottom of the base plate 4. Connecting rods 6 are fixedly connected to adjacent sides of the two mounting blocks 11, serving to connect and transmit force. Two telescopic columns 7 are fixedly connected to the bottom of the base plate 4. The telescopic columns 7 have good telescopic performance, providing stable support for the top plate 9. A spring 8 is sleeved on the outside of the telescopic columns 7. The spring 8 has moderate elasticity, providing cushioning for the pushing movement of the top plate 9. One side of the spring 8 is fixedly connected to the bottom of the base plate 4, and the other side of the spring 8 is fixedly connected to the top of the top plate 9. The bottom of the two telescopic columns 7 is fixedly connected to the top plate 9. The top plate 9 has a moderate area, providing stable support for the workbench. A rotating plate 10 is rotatably connected to the right side of the top plate 9. The rotating plate 10 rotates flexibly, allowing for convenient control of the raising and lowering of the top plate 9.

[0033] Reference Figures 3 to 4 As shown, a U-shaped block 12 is fixedly connected to the right side of the placement platform 1. The U-shaped block 12 is firmly connected and can provide stable support for the fixed cylinder 13. The fixed cylinder 13 is fixedly connected to the outside of the U-shaped block 12. The internal space of the fixed cylinder 13 is moderate and can accommodate the connecting piece 15 and the second spring 14. The second spring 14 is installed inside the fixed cylinder 13. The second spring 14 has good elasticity and can provide pushing force for the locking block 16. The connecting piece 15 is slidably connected inside the fixed cylinder 13. The sliding of the connecting piece 15 is smooth and can drive the locking block 16 to slide inside the fixed cylinder 13.

[0034] A locking block 16 is fixedly connected to the outside of the connecting piece 15. The locking block 16 is reasonably positioned to cooperate with the rotating plate 10 and the pressing block 18 to control the lifting and lowering of the top plate 9. The locking block 16 is externally slidably connected to the inside of the U-shaped block 12. The bottom of the locking block 16 contacts the top of the rotating plate 10. The locking block 16 is externally slidably connected to the inside of the fixed cylinder 13. A sliding pressing assembly is installed on the right side of the placement platform 1. The pressing assembly includes two sliding grooves 17. The sliding grooves 17 are reasonably positioned to provide a track for the sliding of the pressing block 18. The sliding grooves 17 are externally located on the right side of the placement platform 1. The pressing block 18 is slidably connected inside the sliding grooves 17. The sliding of the pressing block 18 is smooth, which can easily control the retraction of the locking block 16.

[0035] Reference Figure 1 and Figure 5 As shown, two fixed boxes 19 are fixedly connected to the left side of the placement platform 1. The connection of the fixed boxes 19 is firm, providing stable support for the arc-shaped groove 20 and the toothed arc plate 21. The arc-shaped groove 20 is opened inside the fixed box 19. The shape of the arc-shaped groove 20 is reasonably designed to restrict the sliding of the toothed arc plate 21. The toothed arc plate 21 is slidably connected inside the arc-shaped groove 20. The toothed arc plate 21 slides smoothly and can shield the coil in the placement groove 3. The toothed arc plate 21 is slidably connected to the inside of the fixed box 19 on the outside, and the toothed arc plate 21 is slidably connected to the inside of the through hole 22 on the outside.

[0036] The placement platform 1 has two through holes 22 inside, and the position of the through holes 22 is reasonably designed to provide a channel for the sliding of the toothed arc plate 21. Rotating rods 23 are rotatably connected inside the two fixed boxes 19. The rotating rods 23 rotate flexibly and can drive the gears 24 to rotate. Two gears 24 are fixedly connected to the outside of the rotating rods 23. The gears 24 are firmly connected and can mesh with the toothed arc plate 21, driving the toothed arc plate 21 to slide. The outside of the toothed arc plate 21 is meshing with the outside of the gears 24. A limiting piece 25 is fixedly connected to the top of one of the fixed boxes 19, which can limit the rotation range of the rotating rods 23.

[0037] Working principle: When medical staff use the placement platform 1, they first place the coils that are not frequently used inside the placement slot 3, and the coils that are frequently used are placed on top of the placement platform 1. This allows for quick retrieval of coils of different radio frequencies. Then, the limit switch is moved to the place of use. After the coil is retrieved, the lowering block 18 is pressed down with the foot, causing the lowering block 18 to slide inside the slide groove 17. At the same time, the bottom of the lowering block 18 presses the top of the two locking blocks 16, causing the locking blocks 16 to retract into the fixed cylinder 13 in conjunction with the connecting piece 15. Then, the telescopic column 7, together with the spring 8, pushes the top plate 9, causing the top plate 9 to push against the ground for support. This prevents the placement platform 1 from shaking when the coils placed inside are retrieved.

[0038] Then, when the top plate 9 needs to be retracted, the rotating plate 10 needs to be stepped on again to make the rotating plate 10 press against the locking block 16 and slide at the bottom of the two locking blocks 16. Then, the locking block 16, together with the connecting piece 15, pushes the locking block 16 through the spring 14 inside the fixed cylinder 13, so that the bottom of the locking block 16 limits the top of the rotating plate 10. At the same time, the rotating plate 10 forms a lever principle through the mounting block 11 and the connecting rod 6, which drives the top plate 9 to retract upward so that the top plate 9 no longer contacts the ground, thereby improving the mobility of the placement platform 1 and allowing it to be placed in a place where it is convenient to pick up and put down the coil during operation.

[0039] Then, when the coil is placed inside the placement slot 3, the rotating rod 23 is rotated, which drives the two gears 24 to rotate. The rotation of the gears 24 drives the toothed arc plate 21 to slide inside the arc groove 20. At the same time, the arc groove 20 limits the toothed arc plate 21, so that the arc groove 20 blocks the coil placed inside the placement slot 3 through the through hole 22 when sliding, thereby preventing the coil from falling out of the placement slot 3, reducing the walking distance, improving the experience and work efficiency of the staff, and facilitating the examination of patients.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
