The purpose of the present invention has been fully and effectively achieved. The function and structural principles of the present invention are shown and described in the following embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.

[0030] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0031] Please see Figure 1-7The illustrated bed protection frame includes a base frame 1 and multiple protective frames 2. The base frame 1 is fixed to the bed. The base frame 1 includes a base frame body 11 and two movable connecting parts 12 disposed on both sides of the base frame body 11. The protective frames 2 include U-shaped frames 21. The U-shaped frames 21 include two main protective rods 211 disposed on both sides. The main protective rods 211 are configured such that one end is rotatably connected to the movable connecting part 12, so that the multiple protective frames 2 can be retracted or extended from the base frame 1. When the multiple U-shaped frames 21 are extended from one end of the bed to the other end via the movable connecting part 12, the open area above the bed is covered by the multiple protective frames 2.

[0032] In some embodiments, the base frame body 11 can be formed by welding metal tubing, and the movable connecting part 12 can be a hinge structure or a bearing structure. The U-shaped frame 21 of the protective skeleton 2 can be formed by bending stainless steel tubing or by injection molding high-strength plastic, and the connection between the main protective rod 211 and the movable connecting part 12 can be a pin connection or a quick-release structure. In the unfolded state, a distance of 10-20cm can be maintained between adjacent U-shaped frames 21 to ensure the protective effect without affecting ventilation. In the retracted state, the protective skeleton 2 can be folded to a position parallel to the base frame 1, saving space.

[0033] In practical use, this invention effectively solves the safety protection problem of the open area above the bed in a mental illness medical environment through its expandable protective frame 2 structure. Compared with traditional fixed-height guardrails, this solution can more comprehensively cover the space above the bed, preventing other patients from committing harmful acts from the open area above the guardrail. The retractable and expandable design of the protective frame 2 ensures both protective effectiveness and ease of operation for medical staff, allowing it to be retracted to save space when there are no safety hazards. The fixed structure of the base frame 1 ensures the stability of the protective frame during use, preventing displacement due to patient collisions.

[0034] Please continue reading. Figure 2 , Figure 3 The base frame body 11 includes a bed end fixing frame 111, two bed side fixing frames 112 disposed at both ends of the bed end fixing frame 111, and a plurality of locking structures 113 respectively disposed on the bed end fixing frame 111; the base frame body 11 is fixed to the bed end of the hospital bed via the locking structures 113, so that the plurality of protective frames 2 can unfold from the bed end of the hospital bed to the bed head end.

[0035] Specifically, the footrest bracket 111 is used to fix the bed to the end of the bed, and the siderest bracket 112 extends along both sides of the bed. The locking structure 113 includes an upper force-bearing plate 1131, a lower mounting plate 1132, and a locking part 1133, which firmly fixes the base frame body 11 to the bed through upper and lower clamping. As a preferred embodiment, the locking part 1133 can adopt a threaded tightening structure or a quick clamping mechanism to achieve quick installation and disassembly. The footrest bracket 111 and the siderest bracket 112 can be connected by welding or bolting to form an integral frame structure. The movable connecting part 12 is preferably located at the end of the siderest bracket 112 and forms a rotatable connection with the main protective rod 211 of the protective frame 2.

[0036] Therefore, this utility model achieves the orderly unfolding of the protective frame 2 from the foot of the bed to the head of the bed through the base frame body 11. The foot-of-bed fixing frame 111 and the side-of-bed fixing frame 112 form a stable installation base, and multiple locking structures 113 ensure reliable fixation of the base frame body 11 to the hospital bed, thus solving the safety hazard problem of the open space above traditional guardrails. The unfoldable protective frame 2 forms a fully covered protective structure. Specifically, when the protective frame 2 is fully unfolded, it can effectively block external attacks from above and to the sides of the hospital bed, providing more comprehensive protection for patients with mental illness.

[0037] Please continue reading. Figure 2 , Figure 3 , Figure 4 The locking structure 113 includes an upper force plate 1131, a lower mounting plate 1132, and a locking part 1133 disposed on the lower mounting plate 1132; the upper force plate 1131 and the locking part 1133 are lowered from the top and bottom respectively to clamp the hospital bed, so that the bed end fixing frame 111 and the bed side fixing frame 112 are fixed to the hospital bed.

[0038] Specifically, the upper load-bearing plate 1131 can be made of stamped metal or injection molded metal, and its contact surface can be equipped with anti-slip textures or rubber pads to enhance friction. The lower mounting plate 1132 is connected to the base frame body 11 by bolts or welding. The locking part 1133 is preferably a structure of wing nut and screw, which facilitates manual adjustment of the tightness. As another embodiment, the locking part 1133 can also adopt a quick clamp mechanism, which achieves single-action locking through the lever principle. The reserved space 1113 allows the locking structure 113 to adapt to bed panels of different thicknesses. Stable fixation can be achieved by adjusting the screw insertion depth or the clamp opening and closing range. In addition, considering that some beds have a rocker arm at the foot of the bed, which is used to rock and change the angle of the bed panel, the reserved space 1113 provides room for the rocker arm to move, thereby avoiding affecting the use of the rocker arm.

[0039] In use, this invention effectively solves the problem of unstable installation of traditional guardrails through its bidirectional clamping design. The clamping force formed by the upper force plate 1131 and the locking part 1133 creates a torque couple, which can counteract the torque generated when the protective frame is deployed. Compared with the single-point fixing method, this structure can prevent the base frame 1 from deflecting or displacing under force, ensuring the stability of the deployment trajectory of the protective frame 2. The rigid connection between the lower mounting plate 1132 and the base frame 1 avoids stress concentration, and the adjustable characteristics of the locking part 1133 allow it to adapt to different specifications of hospital bed frames. This dual fixing mechanism is particularly suitable for psychiatric hospital bed scenarios that need to withstand sudden external forces, providing a reliable installation foundation for the protective frame.

[0040] Please continue reading. Figure 2 , Figure 3 , Figure 4 The bed end fixing frame 111 includes a first vertical plate 1111, a first horizontal plate 1112 disposed on the first vertical plate 1111, and a reserved space 1113 disposed between the first vertical plate 1111 and the bed; the bed side fixing frame 112 includes a second vertical plate 1121 and a second horizontal plate 1122 disposed on the second vertical plate 1121; at least one of the locking structures 113 is disposed on the second vertical plate 1121, and the movable connecting part 12 is disposed at one end of the second vertical plate 1121.

[0041] Specifically, the first longitudinal plate 1111 extends along the length of the bed, and the first transverse plate 1112 extends perpendicular to the first longitudinal plate 1111 and outwards from the bed. A reserved space 1113 allows the first longitudinal plate 1111 to maintain a certain distance from the bed tail frame 42, avoiding direct contact. The second longitudinal plate 1121 extends along the side of the bed, and the second transverse plate 1122 extends perpendicular to the second longitudinal plate 1121 and outwards from the bed. As a preferred embodiment, the locking structure 113 can be fastened with bolts, by rotating the bolts to clamp the upper load-bearing plate 1131 and the locking part 1133 onto the bed side frame 41 from both above and below. The movable connecting part 12 can be a hinge structure, allowing the protective frame 2 to rotate around the hinge axis.

[0042] In use, this utility model achieves stable fixation and flexible retraction of the protective frame on the hospital bed through the arrangement of the bed end fixing frame 111 and bed side fixing frame 112, in conjunction with the locking structure 113 and the movable connecting part 12. The reserved space 1113 avoids interference with the bed end frame 42, the locking structure 113 on the second longitudinal plate 1121 ensures overall fixing strength, and the position design of the movable connecting part 12 allows the protective frame 2 to unfold and retract smoothly. Thus, this utility model optimizes the structural layout and improves installation convenience and usage flexibility while ensuring protective function.

[0043] Please continue reading. Figure 2, Figure 3 , Figure 4 The U-shaped frame 21 includes a top protective frame 212, and two main protective rods 211 are respectively disposed at both ends of the top protective frame 212; when the multiple protective frames 2 are retracted, the top protective frame 212 is configured to be supported by the first horizontal plate 1112, and the two main protective rods 211 are configured to be supported by the two second horizontal plates 1122 respectively.

[0044] In some embodiments, the top protective frame 212 is the horizontal portion of the U-shaped frame 21, with both ends fixedly connected to the main protective rod 211. The top protective frame 212 can be formed by bending metal material; the first horizontal plate 1112 and the second horizontal plate 1122 serve as support structures, and their surfaces can be provided with rubber pads to avoid noise caused by direct metal contact. The support and cooperation between the main protective rod 211 and the second horizontal plate 1122 can be achieved by a groove limiting method, that is, a semi-circular groove matching the outer diameter of the main protective rod 211 is opened on the second horizontal plate 1122. The support contact surface between the top protective frame 212 and the first horizontal plate 1112 can be provided with anti-slip texture to enhance stability.

[0045] In use, this invention achieves stable positioning of the protective frame 2 in its retracted state through the supporting cooperation between the top protective frame 212 and the first horizontal plate 1112, and the supporting cooperation between the main protective rods 211 and the second horizontal plate 1122. Specifically, when the protective frame 2 is retracted, the top protective frame 212 rests horizontally on the first horizontal plate 1112, and the two main protective rods 211 lean against the second horizontal plates 1122 on both sides, forming a three-point support structure. This support method effectively prevents the protective frame 2 from shaking or shifting in the retracted state, and at the same time facilitates medical personnel to quickly confirm whether the protective frame 2 is fully retracted, thus solving the problem of unstable positioning of the protective frame 2 in the retracted state. A reliable support effect is achieved through a simple mechanical structure without affecting the normal unfolding function of the protective frame 2.

[0046] Please continue reading. Figure 2 , Figure 3 , Figure 4 The main protective rod 211 includes a first rotating part 2111 disposed at one end away from the top protective frame 212, the first rotating part 2111 cooperating with the movable connecting part 12; the main protective rod 211 further includes at least one second rotating part 2112.

[0047] Specifically, the first rotating part 2111 is used to achieve a rotatable connection between the main protective rod 211 and the movable connecting part 12 of the base frame 1, allowing the protective frame 2 to be retracted or extended around the base frame 1. The second rotating part 2112 is located at other positions on the main protective rod 211 and is used to connect the secondary protective rod 22. The first rotating part 2111 and the second rotating part 2112 can adopt a hinge structure, a bearing structure, or other mechanical structures that can achieve a rotatable connection. As a preferred embodiment, the first rotating part 2111 adopts a hinge with a damping effect to control the speed at which the protective frame 2 extends or retracts. The second rotating part 2112 can adopt a quick-release pin structure to facilitate the installation and maintenance of the secondary protective rod 22.

[0048] In use, this invention achieves multi-point connection and coordinated deployment of the protective frame 2 by setting a first rotating part 2111 and a second rotating part 2112 on the main protective rod 211. The first rotating part 2111 ensures that the protective frame 2 can rotate stably around the base frame 1, and the second rotating part 2112 provides a connection point for the secondary protective rod 22, so that the protective frame 2 can form a more complete protective structure when deployed. This solves the safety hazard problem of open space above traditional guardrails. Through the multi-point connected rotating structure, the stable deployment and retraction of the protective frame 2 are achieved, improving the protection effect for patients in hospital beds.

[0049] Please continue reading. Figure 3-6 The protective frame 2 further includes a plurality of secondary protective rods 22; the secondary protective rods 22 are disposed on the second rotating part 2112 of two adjacent main protective rods 211; when the protective frame 2 is deployed, the secondary protective rods 22 are deployed along with the two adjacent main protective rods 211.

[0050] Specifically, the secondary protective rod 22 is hinged to the main protective rod 211 via the second rotating part 2112, allowing the secondary protective rod 22 to move synchronously with the rotation of the main protective rod 211. In a preferred embodiment, the secondary protective rod 22 can be configured as two sections connected by a pivot, enabling the two sections of the secondary protective rod 22 to expand or retract synchronously with the expansion or retraction of the main protective rod 211. The secondary protective rod 22 can adopt a structure similar to the main protective rod 211, with connecting holes at both ends that mate with the second rotating part 2112. For example, the second rotating part 2112 can adopt a lug structure with through holes, and the secondary protective rod 22 is rotatably connected to the lug via a pin. Thus, during the expansion of the protective frame 2, the secondary protective rod 22 can automatically expand to form a supplementary protective structure.

[0051] In use, this invention effectively fills the gaps between adjacent main protective bars 211 by adding secondary protective bars 22 between them. When the protective frame 2 is fully extended, the secondary protective bars 22 and the main protective bars 211 together form a continuous protective net, significantly improving the coverage density of the open area above the hospital bed. Compared with the solution that only sets the main protective bars 211, this structure can better prevent external objects from intruding through the gaps in the protective frame 2, and is particularly suitable for mental illness medical environments that require high levels of protection. At the same time, the secondary protective bars 22 are linked to the main protective bars 211 through the second rotating part 2112, and can be retracted or extended synchronously with the main protective bars 211 without additional operation, maintaining ease of use.

[0052] Please continue reading. Figure 7 The present invention further includes a protective sleeve 3; the protective sleeve is disposed on a plurality of protective frames 2, and is retracted or expanded with the plurality of protective frames 2.

[0053] Specifically, the protective sleeve 3 primarily addresses the safety hazards present in the open area above traditional hospital bed rails. When the protective frame 2 is deployed, the protective sleeve 3 and the protective frame 2 together form a continuous protective barrier, completely covering the open space above the hospital bed. This not only prevents patients from falling but also effectively blocks external attacks from the sides and above. Compared to a structure with only a metal frame, adding the protective sleeve 3 retains the support strength of the frame while using flexible materials to buffer potential impacts. It also avoids secondary injuries that could result from direct contact between metal parts and the patient. Thus, through a simple structural improvement, the overall protective performance of the hospital bed is significantly enhanced without affecting the original retraction and deployment function of the protective frame. It is also worth noting that, to facilitate observation of the patient's condition inside the protective sleeve 3, it is preferably made of a transparent and breathable material.

[0054] Please continue reading. Figure 8-9 The protective hospital bed shown includes a bed frame 4, a bed board 5, and a protective frame; the bed board 5 is disposed on the bed frame 4; the protective frame includes a base frame 1 and multiple protective frames 2; the base frame 1 is fixed to the hospital bed; the base frame 1 includes a base frame body 11 and two movable connecting parts 12 disposed on both sides of the base frame body 11; the protective frames 2 include U-shaped frames 21; the U-shaped frames 21 include two main protective rods 211 disposed on both sides; the main protective rods 211 are configured to be rotatably connected at one end to the movable connecting part 12, so that the multiple protective frames 2 can be retracted or extended from the base frame 1; when the multiple U-shaped frames 21 are extended from one end of the hospital bed to the other end via the movable connecting part 12, the open area above the hospital bed is covered by the multiple protective frames 2; the base frame 1 is detachably connected to the bed frame 4.

[0055] Specifically, the bed frame 4 includes a side frame 41 and a tail frame 42. The tail frame 111 of the base frame body 11 is fixed to the tail frame 42 by a locking structure 113, and the side frame 112 fits against the outer side of the side frame 41. The upper force plate 1131 and the locking part 1133 of the locking structure 113 clamp the side frame 41, and the reserved space 1113 is set between the tail frame 42 and the first longitudinal plate 1111. The top protective frame 212 and the main protective rod 211 of the protective frame 2 are supported by the first horizontal plate 1112 and the second horizontal plate 1122, respectively, when the frame is folded up. The first rotating part 2111 of the main protective rod 211 cooperates with the movable connecting part 12, and the second rotating part 2112 connects to the auxiliary protective rod 22. The protective sleeve 3 is set on the protective frame 2 and folds up or unfolds with it.

[0056] In actual use, this protective bed achieves coverage of the open area above the bed through a detachable bed guardrail. The folding and unfolding structure of the protective frame 2 facilitates operation, while the locking structure 113 and the reserved space 1113 enhance the stability of the base frame 1. The protective sleeve 3 further improves the protective effect, thus solving the safety hazards of the open space above traditional bed rails and providing more comprehensive protection for patients in mental illness medical environments.

[0057] Please continue reading. Figure 8-9 The bed frame 4 includes two bed side frames 41 disposed on both sides of the bed board 5 and a bed tail frame 42 disposed at the rear of the bed board 5; the second longitudinal plate 1121 is configured to fit against the outer side of the bed side frame 41; the upper force plate 1131 and the locking part 1133 are respectively lowered from the top and bottom to clamp the bed side frame 41; the reserved space 1113 is disposed between the bed tail frame 42 and the first longitudinal plate 1111.

[0058] Specifically, the structural design of the bed frame 4 allows the bed support frame to be stably installed on the bed. The side frames 41 and the tail frame 42 provide a reliable fixing base for the base frame 1. The second longitudinal plate 1121 fits against the outer surface of the side frame 41, increasing the contact area and improving stability. The upper force plate 1131 and the locking part 1133 are fixed to the side frame 41 by clamping from above and below, preventing the base frame 1 from shifting under stress. The reserved space 1113 allows a certain distance to be maintained between the base frame 1 and the tail frame 42, avoiding friction or interference with the rocker structure of the bed caused by direct contact.

[0059] In a preferred embodiment, the upper force-bearing plate 1131 and the locking part 1133 can be clamped using bolts or a quick-clamping mechanism. The size of the reserved space 1113 can be adjusted according to the thickness of different bed tail frames 42 to ensure compatibility. The outer surface of the bed side frame 41 can be provided with anti-slip textures or rubber pads to enhance friction with the second longitudinal plate 1121.

[0060] Therefore, this invention solves the problem of unstable installation of traditional hospital bed protective frames by optimizing the connection method between the bed frame 4 and the base frame 1. The tight fit between the base frame 1 and the bed frame 4 ensures the stability of the protective frame 2 during unfolding and retraction, avoiding protective failure caused by loosening of the base frame 1. The reserved space 1113 design ensures both installation flexibility and avoids structural interference. Compared with the prior art, this solution significantly improves the safety and reliability of the protective hospital bed, and is especially suitable for mental illness medical environments that require prevention of violence between patients.

[0061] The above description only illustrates the preferred embodiment of this utility model and should not be construed as limiting the scope of the claims. This utility model is not limited to the above embodiments, and variations in its specific structure are permitted. All changes made within the scope of the independent claims of this utility model are also within the scope of protection of this utility model.
