Description

Technical Field

In addition, the protective positioning structure of the side panels is mostly a pin-type structure, and its positioning and unlocking procedures are cumbersome. The coordination between the lifting and protective functions is poor, and the overall functionality is relatively simple, making it difficult to meet the convenience and safety requirements of clinical nursing.

[0066] like Figures 1 to 8 As shown, this utility model embodiment provides a lockable lifting bracket for bed frame accessories and a medical bed including the lockable lifting bracket. The lockable lifting bracket includes a base structure 1, a top support structure 2, side support arm structures 3, a central support arm structure 4, a damping gas spring structure 5, and a positioning lock structure 6. These components effectively mount a protective plate on the bed frame and construct a parallelogram structure to ensure the protective plate remains vertical during lifting, improving stability. Simultaneously, the damping gas spring structure 5 provides damping buffer when the protective plate descends, avoiding impact and enhancing safety. Furthermore, the positioning lock structure 6, based on a torsion spring, achieves reliable locking and positioning, and can be easily unlocked via a locking control unit, thus achieving efficient synergy between lifting and protective functions. Specific settings are as follows:

[0067] Please refer to Figures 1 to 4 The base structure 1 includes a base body 11, a bottom center transition groove 12, and two sets of bottom side transition grooves 13. The base body 11 is fixed to a predetermined bed body to provide a stable support foundation. The bottom center transition groove 12 is positioned in the middle of the base body 11. The two sets of bottom side transition grooves 13 are positioned on the base body 11, and the two sets of bottom side transition grooves 13 are respectively located on both sides of the bottom center transition groove 12 to assemble the side support arm structure 3.

[0068] The top support structure 2 includes a top support body 21, a top center transition groove 22, and two sets of top side transition grooves 23. The top support body 21 is fixed to a predetermined bed board to drive the bed board to rise and fall synchronously. The top center transition groove 22 is positioned in the middle of the top support body 21 and is correspondingly arranged with the bottom center transition groove 12 to realize the assembly connection of the central support arm structure 4. The two sets of top side transition grooves 23 are positioned on the top support body 21 and are respectively located on both sides of the top center transition groove 22. The two sets of top side transition grooves 23 are respectively corresponding to the two sets of bottom side transition grooves 13 to realize the assembly connection of the side support arm structure 3.

[0069] Please continue to refer to this. Figures 1 to 4 The side support arm structure 3 is provided in two sets, and the two sets of side support arm structures 3 are respectively assembled between the two sets of top side transition grooves 23 and the two sets of bottom side transition grooves 13. Specifically, the top part of the side support arm structure 3 is connected to the top side transition groove 23 via shaft a, and the bottom part of the side support arm structure 3 is connected to the bottom side transition groove 13 via shaft b, so as to realize the rotational support of the side support arm through shaft connection.

[0070] The central support arm structure 4 includes a central support arm body 41 and a bottom transition part 42 and a top transition part 43 respectively located at the bottom and top ends of the central support arm body 41. The central support arm body 41 is connected to the bottom center transition groove 12 via the bottom transition part 42 through the shaft c, and the central support arm body 41 is connected to the top center transition groove 22 via the top transition part 43 through the shaft d, so as to realize the rotational support of the central support arm. A locking through groove 44 is also provided in the middle position of the central support arm body 41, so as to assemble the positioning locking structure 6 through the locking through groove 44.

[0071] Please continue to refer to this. Figure 4 The lines connecting axes a and d, corresponding to the same longitudinal plane, and the lines connecting axes b and c, corresponding to the same longitudinal plane, are of equal length and parallel to each other, forming a parallelogram structure. This allows the fixed bed board of the top support structure 2 to always maintain a vertical state and adjust its height while the bottom base structure 1 remains vertically fixed to the predetermined bed body, thus improving the stability of lifting and lowering.

[0072] Please continue to refer to this. Figures 1 to 3One end of the damping gas spring structure 5 is adapted to be mounted on the bottom base body 11, and the other end of the damping gas spring structure 5 is adapted to be mounted on the upper middle part of the central support arm body 41. The gas support force of the damping gas spring structure 5 is less than the weight of the top support structure 2 and the predetermined bed board. It is used to dampen and buffer the top support structure 2 and its connected bed board when the height decreases, avoids the impact caused by rapid falling, and improves the overall safety and functional practicality.

[0073] Please refer to Figures 5 to 7 The positioning latch structure 6 is assembled in the latch through groove 44. Specifically, the positioning latch structure 6 includes a positioning latch body 61, a latch part 62, a locking operation part 63, and a torsion spring 64. The positioning latch body 61 is rotated and assembled in the middle position on the inner wall of the latch through groove 44, and a torsion spring 64 is rotatably sleeved between the positioning latch body 61 and the inner wall of the latch through groove 44. One supporting end of the torsion spring 64 abuts against the positioning latch body 61, and the other supporting end of the torsion spring 64 abuts against the inner wall of the latch through groove 44 to provide elastic support force.

[0074] The positioning latch body 61 has a latch part 62 on the inner side facing the center support arm body 41. The latch part 62 has an upward-opening latch groove, which is used to detachably latch and limit the positioning of the positioning rod on the side of the bed through the latch groove. The latching and limiting effect is maintained by the elastic support of the torsion spring 64, thereby keeping the center support arm structure 4 and the bed board in the predetermined protective position and ensuring the reliability of the protection.

[0075] The positioning lock body 61 is provided with a locking operation part 63 on the outer side facing the central support arm body 41. The locking operation part 63 is used to pull back to make the locking part 62 move down by lever action, thereby releasing the locking groove from the positioning rod on the side of the bed, so that the top support structure 2 and its connecting bed board can automatically lower the height based on their own weight, thereby effectively realizing the convenient unlocking of the guard plate.

[0076] In summary, through the coordinated operation of its various components, this support system effectively solves the coordination problem between the lifting and protection of medical bed linens, thereby improving the convenience and safety of nursing procedures.

[0077] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
