[0046] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model more clear, the technical scheme in the embodiments of the utility model is clearly and completely described. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the utility model.

[0047] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 , the drawer type variable amplitude guardrail comprises a transfer bed board 100; two extension bed boards 300 are symmetrically arranged at the bottom of the transfer bed board 100, the two extension bed boards 300 are arranged to be close to or away from each other as needed, and the two extension bed boards 300 are moved upward and unfolded after moving away from each other, and can be in the same horizontal plane as the transfer bed board 100, and the two extension bed boards 300 are moved downward and gathered after moving close to each other, and can be retracted and stored in the bottom of the transfer bed board 100.

[0048] The two extension bed boards 300 of the embodiment can be simultaneously lifted to the same horizontal plane as the transfer bed board 100 when moving and unfolding, thereby forming a continuous and flat sleeping area with the transfer bed board 100, so as to improve the comfort and safety of the patient, and the space of the transfer bed is not occupied when being stored.

[0049] Referring to Figure 2 and Figure 3 , two amplitude guide rails 400 are installed at the bottom of the transfer bed board 100, and have a lifting section and a lifting transition section from bottom to top. The lifting section is used to lift the height of the extension bed board 300, and the lifting transition section is used to unfold the extension bed board 300. The two extension bed boards 300 are respectively connected with the two amplitude guide rails 400 in a sliding manner, and the amplitude guide rail 400 is used to provide a moving path for the extension bed board 300, so as to ensure the stability and safety of the extension bed board 300 during unfolding and folding, so that the extension bed board 300 can move smoothly and smoothly, reduce noise and vibration, and improve the comfort of the patient.

[0050] Referring to Figure 4Each amplitude guide rail 400 includes a guide hole 402 formed on the amplitude guide rail 400, and both sliders 302 are movably connected (slidingly or rotatably) in the guide hole 402, so that the sliders 302 can slide or roll in the guide hole 402.

[0051] Referring to Figure 2 and Figure 3 Each extension bed board 300 includes a support plate 301 and two sliders 302. The support plate 301 is installed at the bottom of the extension bed board 300, and the extension bed board 300 is connected to the amplitude guide rail 400 through the sliders 302 provided on the support plate 301. The support plate 301 provides necessary support for the extension bed board 300. Both sliders 302 are installed on the support plate 301, one at the middle position of the support plate 301 and the other at the end of the support plate 301, and both sliders 302 are connected to the amplitude guide rail 400 through the guide hole 402. The support plate 301 is slidingly connected to the amplitude guide rail 400 through the sliders 302, ensuring the stability and safety of the extension bed board 300 during movement. The design of the slider 302 enables the extension bed board 300 to move smoothly along the amplitude guide rail 400, reducing friction and resistance and improving the efficiency and reliability of the entire system.

[0052] In addition, the amplitude guide rail 400 further includes a connecting piece 401, one end of which is installed on the amplitude guide rail 400 and the other end of which is connected to the transfer bed board 100. The connecting piece 401 enables the amplitude guide rail 400 to be stably fixed to the lower end surface of the transfer bed board 100.

[0053] Referring to Figure 2 and Figure 3 In one embodiment, both amplitude guide rails 400 are formed with inner elbows 404 at one end close to the bottom of the transfer bed board 100, and the bending direction of the inner elbow 404 is inward toward the middle of the two amplitude guide rails 400. The two inner elbows 404 are symmetrically arranged, and the design of the inner elbow 404 enables the slider 302 at the middle position of the support plate 301 to fall into the curved area of the inner elbow 404 after the extension bed board 300 is fully unfolded, so that the position of the extension bed board 300 is more stable after unfolding. When the patient lies on the transfer bed board 100 and the extension bed board 300, the weight of the patient's own body will exert downward pressure, and the greater the pressure, the more stable the position of the slider 302 in the inner elbow 404.

[0054] Referring to Figure 4 In a preferred embodiment, the inner elbow 404 is provided with a limiting structure 403 at the end, which is used to limit the position of the slider 302 at the middle position of the support plate 301, so as to better stabilize the position of the slider 302 and make the extension bed board 300 more stable and firm when bearing the weight pressure of the patient after unfolding.

[0055] In another embodiment, the tail end of the guide hole 402 (i.e. the end opposite to the inner elbow 404) is also provided with a limiting structure 403, which is used to limit the position of the slider 302 at the tail end of the support plate 301 when it is not actively moved. The limiting structure 403 cooperates with the inner elbow 404 to ensure the stability of the extension bed plate 300 after it is folded out or folded in, and prevent the extension bed plate 300 from shifting or wobbling during movement.

[0056] In another preferred embodiment, the middle section of the guide hole 402, i.e. the area matching the slider 302 at the middle of the support plate 301, is also provided with a limiting structure 403, which further facilitates the stability of the extension bed plate 300 when it is folded out or folded in.

[0057] The limiting structure 403 described above is a downwardly recessed groove, which allows the slider 302 to be inwardly recessed downward when it is located in the inner elbow 404, and is not easy to fall off.

[0058] Referring to Figure 7 In another embodiment, the limiting structure 403 is an elastic buckle, which can clamp the slider 302 when it is located in the inner elbow 404, but can be easily pulled out by applying a little force when the slider 302 is pulled out. Specifically, the elastic buckle is a ring-shaped elastic metal buckle. When the slider 302 is clamped into the elastic buckle, the elastic buckle restores the deformation and wraps the slider 302 halfway. Further, in order to make the elastic buckle clamp the slider 302 more firmly, a preferred way is that three semispherical protrusions are fixedly connected inside the elastic buckle. The three semispherical protrusions are correspondingly arranged to form a triangle, and the triangle direction ensures the stability of the elastic buckle clamping.

[0059] More preferably, the limiting structure 403 is a combination of a groove and an elastic buckle.

[0060] In an embodiment, in order to ensure the comfort of the patient lying down, a preferred way is that the surface space of the transfer bed plate 100 and the extension bed plate 300 is adapted, and the transfer bed plate 100 further comprises a fixed mattress 101 and two folding mattresses 200. The fixed mattress 101 is laid on the surface of the transfer bed plate 100, and the two folding mattresses 200 are respectively arranged on the two sides of the fixed mattress 101.

[0061] Preferably, the two folding mattresses 200 are respectively movably connected on the two sides of the fixed mattress 101, and can be unfolded or folded according to actual needs to adapt to patients of different body sizes, thereby improving the flexibility and adaptability of the mattress.

[0062] In another embodiment, the extension bed board 300 further comprises a side rail 500 installed on one side of the extension bed board 300, and a handle 501 installed on the side rail 500. The side rail 500 can move with the extension bed board 300 to provide additional safety protection for the patient, preventing the patient from rolling off the bed during sleep, and improving the safety and reliability of the bed. The handle 501 facilitates the medical staff or patient family members to grasp the force when moving or adjusting the position of the bed.

[0063] In a preferred embodiment, in order to facilitate storage and reduce the storage space of the guardrail as much as possible when not in use, a preferred way is that the side rail 500 is connected to one side of the extension bed board 300 by a hinge. When the side rail 500 is not needed or it is convenient for the patient to get on and off the bed, the side rail 500 can be turned down for storage.

[0064] The following briefly introduces the use principle and method of the drawer-type variable amplitude guardrail proposed in this application:

[0065] During the use of the transfer bed by medical staff, the transfer bed board 100 can generally adapt to most patients with regular body types in the normal state, at this time, the two extension bed boards 300 are symmetrically arranged at the bottom of the transfer bed board 100 and are in the storage state, that is, one end of the support plate 301 of the sliding block 302 is located in the limiting structure 403 at the tail end of the amplitude guide rail 400, and does not occupy the transfer bed space.

[0066] Referring to Figure 5 and Figure 6 When the patient's body type is large and wide, the normal transfer bed board 100 cannot support the patient, or the bed board is too narrow to make the patient uncomfortable, the two extension bed boards 300 can be unfolded to widen the bed amplitude. At this time, the medical staff or patient family members can turn the side rail 500 upward, then hold the handle 501, and slightly apply force to the upper oblique direction to pull, so that the extension bed board 300 moves stably along the guide hole 402 of the amplitude guide rail 400, and the sliding block 302 slides out of the corresponding limiting structure 403 and slides in the guide hole 402. As the two extension bed boards 300 move away from each other, the extension bed board 300 will rise along the track of the amplitude guide rail 400 until it rises to the highest position of the amplitude guide rail 400, at this time, the sliding block 302 at the middle position of the support plate 301 will fall into the limiting structure 403 of the curved area of the inner elbow 404 to stabilize the position of the extension bed board 300 until it is at the same level as the transfer bed board 100.

[0067] When the extension bed board 300 is fully unfolded, the folding mattress 200 is unfolded, and the fixed mattress 101, the folding mattress 200 and the extension bed board 300 jointly form a continuous and flat sleep area to adapt to patients with larger body sizes, and the patient can lie stably on the sleep area formed by the fixed mattress 101, the folding mattress 200 and the extension bed board 300.

[0068] The side rail plate 500 provides safety protection at the edge for the patient to prevent the patient from rolling out of the bed during turning over and the like, and when the patient leaves the bed, the medical staff or the patient's family members can hold the handle 501 and follow the reverse steps to retract the extension bed board 300 along the amplitude guide rail 400 to the initial position, and the sliding block 302 slides in the guide hole 402 until the sliding block 302 at the tail position of the support plate 301 falls into the limiting structure 403 at the tail end of the guide hole 402, ensuring the stability and safety of the retraction process. When the extension bed board 300 is fully retracted, the two extension bed boards 300 do not occupy the space of the transfer bed board 100, facilitating subsequent transfer and movement, and at this time, the tail end sliding block 302 falls into the limiting mechanism in the guide hole 402, which can stabilize the position of the extension bed board 300 after retraction.

[0069] In summary, compared with the prior art, the drawer type variable amplitude guardrail has the following beneficial effects:

[0070] Through the precise design of the amplitude guide rail and the ingenious use of the inner elbow, the extension bed board can move smoothly and smoothly during unfolding and folding, reducing the risk of shaking and deviation, and the design of the inner elbow enables the sliding block to fall into the limiting structure 403 in the curved area after full unfolding, stabilizing the position of the extension bed board. In addition, the extension bed board can be on the same horizontal plane as the transfer bed board after unfolding, ensuring the safety and comfort of the patient when lying down.

[0071] The extension bed board can be flexibly unfolded or folded according to the size of the patient's body, providing a flexible sleep area for the patient, and the design of the folding mattress further increases the comfort of the bed, which can meet the needs of different patients; the extension bed board is completely hidden in the bottom of the transfer bed board 100 when it is stored, does not occupy additional space, improves the space utilization rate, and is especially suitable for medical environments with limited space.
