Description

Technical Field

[0001] This utility model relates to the field of bed safety guards, and in particular to a bed safety guard for intensive care. Background Technology

[0002] Bed rails, also known as bed guardrails, are protective rails built on the sides of infant / adult beds. For fall-prevention bed rails used in intensive care, the entire bed rail needs to have a height-adjustable and foldable structure. Fall-prevention bed rails are directly installed on both sides of the hospital bed as a basic protective barrier, suitable for most high-risk patients.

[0003] For some elderly patients, the pain may cause them to shake the bed rails. Since these beds use a height-adjustable and foldable structure, if the shaking direction is the same as the patient's lying direction, the bed rails have a locking mechanism in that direction, so their protective performance will not be affected. However, if the shaking direction is horizontal or perpendicular to the patient's lying direction, the bed rails are foldable, so their support strength in that direction is limited. Over time, this may cause the bed rail connections to loosen, affecting the overall lifespan of the bed rails and reducing their support strength. Utility Model Content

[0004] The purpose of this invention is to provide a fall-prevention bed rail for intensive care to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A fall-prevention bed rail for intensive care includes a bed frame, two bed rails, and two support mechanisms. The two bed rails are located on the sides of the bed frame, and the two support mechanisms are located on the sides of the bottom of the bed frame. Each support mechanism is equipped with a locking mechanism on its underside.

[0007] The bed rails include armrests, with a reinforcing frame underneath. Three flip rods are hinged between the armrests and the reinforcing frame.

[0008] The support mechanism includes a fixed frame with three rotating shafts rotatably connected to it. Each rotating shaft has a gear fixed on it, and each of the three gears has a rack meshing with it. One end of the rotating shaft extending out of the fixed frame is fixed to the lower side of the flipping rod. A reinforcing rod is provided between two adjacent gears, and a fastening buckle is fixed to the lower end of each reinforcing rod.

[0009] The locking mechanism includes two mating seats, both of which are fixed to the bottom of the reinforcing frame. Each mating seat has a side plate fixed on the side away from the buckle. Each side plate has a spring fixed on it, and each spring has a U-shaped buckle fixed on the other end.

[0010] Preferably, the rack is slidably connected to the fixed frame, and all three gears are located inside the fixed frame.

[0011] Preferably, the upper end of the reinforcing rod is fixedly connected to the rack.

[0012] Preferably, the mating seat has a sliding groove for the U-shaped latch to slide, and the mating seat has a slot at the end away from the side plate.

[0013] Preferably, the fastener has a locking slot for corresponding to the groove.

[0014] Preferably, the U-shaped latch has a locking hook fixed at one end within the sliding groove, and the locking opening corresponds to the groove opening and the locking opening.

[0015] Preferably, an unlocking lever is fixed at the end of the two U-shaped latches away from the mating seat.

[0016] The advantages compared with the existing technology are as follows: the U-shaped locking buckle locks the fastening buckle and the mating seat, and the cooperation between the rotating shaft and the flipping rod improves the stability of the entire bed rail. At the same time, the support of the mating seat at the bottom of the reinforcement frame by the reinforcing rod and the fastening buckle improves the support strength of the entire bed rail.

[0032] The present invention will be further described below with reference to the accompanying drawings:

[0033] like Figures 1-11 As shown, a fall-prevention bed rail for intensive care includes a bed frame 1, two bed rails 2 and two support mechanisms 3. The two bed rails 2 are located on the sides of the bed frame 1, and the two support mechanisms 3 are located on the sides of the bottom of the bed frame 1. Each support mechanism 3 is provided with a locking mechanism 4 on its lower side.

[0034] In this embodiment: the bed rail 2 includes a handrail 21, and a reinforcing frame 23 is provided below the handrail 21. Three flip rods 22 are hinged between the handrail 21 and the reinforcing frame 23. Pushing the handrail 21 will make the three flip rods 22 vertical, thereby placing the reinforcing frame 23 below the support mechanism 3.

[0035] In this embodiment: the support mechanism 3 includes a fixed frame 31, on which three rotating shafts 32 are rotatably connected. Each rotating shaft 32 is fixed with a gear 33, and each of the three gears 33 is meshed with a rack 34. One end of the rotating shaft 32 extending out of the fixed frame 31 is fixed to the lower side of the flipping rod 22. A reinforcing rod 35 is provided between two adjacent gears 33. Each reinforcing rod 35 has a fastening buckle 36 fixed at its lower end. The rack 34 is slidably connected to the fixed frame 31. All three gears 33 are located inside the fixed frame 31. The upper end of the reinforcing rod 35 is fixedly connected to the rack 34. The flipping of the flipping rod 22 drives the rotating shafts 32 and gears 33 to rotate. The rotation of the gears 33 drives the rack 34 and reinforcing rod 35 to move on the fixed frame 31. The movement of the reinforcing rod 35 drives the fastening buckle 36 to move closer to the locking mechanism 4 for engagement.

[0036] In this embodiment: the locking mechanism 4 includes two mating seats 41, both of which are fixed to the bottom of the reinforcing frame 23. Each mating seat 41 has a side plate 42 fixed on the side away from the fastening buckle 36. A spring 45 is fixed on each side plate 42, and a U-shaped latch 44 is fixed on the other end of each spring 45. An unlocking rod 43 is fixed to the end of each U-shaped latch 44 away from the mating seat 41. The mating seat 41 has a sliding groove for sliding the U-shaped latch 44, and a slot is opened on the end of the mating seat 41 away from the side plate 42. The fastening buckle 36 has a locking hole for corresponding to the slot. A locking hook is fixed to the end of the U-shaped latch 44 located in the sliding groove, and the locking hook corresponds to the slot and the locking hook. The movement of the latch 36 pushes the hook of the U-shaped latch 44, causing the U-shaped latch 44 to slide along the sliding groove, thereby retracting the hook that extends out of the groove back into the sliding groove. Then, the latch 36 and the mating seat 41 are engaged. At the same time, the spring 45 pushes the U-shaped latch 44 along the sliding groove toward the unlocking rod 43, thereby pushing the hook that has retracted into the sliding groove out of the groove again, and making the hook that has been pushed out of the groove engage with the locking mouth of the latch 36, thereby fixing the latch 36 and the mating seat 41. Then, the reinforcement frame 23 is placed in this position, and the position after the flipping rod 22 is flipped is fixed, and the side of the bed frame 1 is protected.

[0037] Working principle: When in use, first push the armrest 21 to move towards the foot of the bed. At this time, the three flip rods 22 on the lower side of the armrest 21 flip with their lower pivot 32 as the center, so that the armrest 21 moves diagonally upward and the three flip rods 22 are in a vertical state. At the same time, the reinforcing frame 23 at the lower end of the three flip rods 22 moves in the opposite direction to the armrest 21, so that the reinforcing frame 23 is located below the fixed frame 31.

[0038] During this process, as the flipping rod 22 flips, it drives the rotating shaft 32 and gear 33 to rotate. The rotation of gear 33 drives the rack 34 and reinforcing rod 35 to move on the fixed frame 31. The movement of reinforcing rod 35 drives the fastening buckle 36 to move closer to the mating seat 41.

[0039] When the latch 36 is about to engage with the U-shaped latch 44, the movement of the latch 36 pushes the hook of the U-shaped latch 44, causing the U-shaped latch 44 to slide along the sliding groove, thereby retracting the hook that extends out of the groove back into the sliding groove. Then, the latch 36 and the mating seat 41 engage with each other. At the same time, the spring 45 pushes the U-shaped latch 44 along the sliding groove towards the unlocking rod 43, thereby pushing the hook that has retracted into the sliding groove out of the groove again, and making the hook that has been pushed out of the groove engage with the latch 36, thereby fixing the latch 36 and the mating seat 41. Then, the reinforcement frame 23 is in this position, and the position after the flipping rod 22 is flipped is fixed, and the side of the bed frame 1 is protected. In addition, the reinforcement rod 35 and the latch 36 support the mating seat 41 at the bottom of the reinforcement frame 23, thereby improving the stability of the bed rail 2.

[0040] When the bed rail 2 needs to be lowered, pressing the unlocking lever 43 pushes the two U-shaped latches 44 inward along the sliding groove, causing the latch hooks on the U-shaped latches 44 to disengage from the locking jaws of the buckle 36 and retract back into the sliding groove. At the same time, the spring 45 is compressed, and then the armrest 21 can be pushed forward. The quadrilateral structure allows the armrest 21 to overlap with the reinforcing frame 23, thus completing the process of lowering the bed rail 2.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
