Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a guardrail structure and a medical bed. BACKGROUND

[0002] The medical bed, also known as a nursing bed or a medical bed, is a necessary device for treating and nursing patients in a hospital. Since the medical bed is usually a single bed with a narrow width, considering the possibility that some patients on the medical bed may fall off the bed due to repeated turning movements caused by pain or unconsciousness, most medical beds in hospitals need to be equipped with bed guardrails.

[0003] In order to balance the protection function and the portability of the patient getting out of bed, the guardrail often adopts a foldable form. For example, the horizontal rod is fixed, and a plurality of vertical rods are rotatably connected to the horizontal rod; or the vertical rod is fixed, and a plurality of horizontal rods are rotatably connected to the vertical rod. Among them, when the rotating rod in the horizontal rod and the vertical rod is moved to the required position, the rotating rod and the bed frame are fixed by using bolts, nuts and other components, and after the fixing is completed, the bolts and nuts are removed.

[0004] However, the process of using bolts, nuts and other components to lock and unlock the rotating rod in the horizontal rod and the vertical rod with the bed frame is not only complicated, but also often takes a long time in actual operation, which brings inconvenience to the patient getting on and off the bed and the caregiver. SUMMARY

[0005] Therefore, the present application provides a guardrail structure and a medical bed to solve the problem of complicated locking and unlocking process of the side guardrail in the prior art.

[0006] In a first aspect, the present application provides a guardrail structure, comprising a guardrail and a self-locking assembly. The guardrail is installed on the long side of the bed frame, and the guardrail has a first fixed state of complete folding, a second fixed state of complete unfolding, and an adjustment state of one of the first fixed state and the second fixed state transitioning to the other; the self-locking assembly comprises a fixed plate body, a rotating plate body and an elastic brake, the fixed plate body is fixedly installed on the bed frame, the rotating plate body is installed on the guardrail and the rotating plate body is rotatably connected to the fixed plate body, and the elastic brake has an initial position when the guardrail is in the first fixed state and a fixed position when the guardrail is in the second fixed state, the elastic brake has a first natural state when in the initial position, a second natural state when in the fixed position, and a deformation state transitioning from one of the first natural state and the second natural state to the other.

[0007] Beneficial effects: By fixing the fixed plate body to the bed frame, connecting and rotating the plate body with the guardrail, and using the elastic brake, the state of the guardrail can be conveniently switched by using the elastic brake in different states, so that the caregiver can easily adjust the guardrail to the required state as needed, without the need for additional locks or tools to disassemble or reinstall the guardrail, which helps to simplify the process of fixing and unlocking the guardrail, and reduces the operation difficulty of the caregiver.

[0008] In an optional embodiment, the self-locking assembly further comprises a guide plate body connected with the fixed plate body, the guide plate body is in the path of the elastic brake moving from the initial position to the fixed position, and the guide plate body is used to abut against the elastic brake.

[0009] Beneficial effects: By providing a guide plate body in the path of the elastic brake from the initial position to the fixed position, the elastic brake is guided to avoid the situation that the locking fails or is not firm due to deviation, and in the process of rotating the guardrail with the elastic brake, the elastic brake directly abuts against the surface of the guide plate body, making the process of switching the state of the elastic brake more reliable, thereby making the process of switching the state of the guardrail more reliable.

[0010] In an optional embodiment, the guide plate body is installed at an angle with the fixed plate body.

[0011] Beneficial effects: By installing the guide plate body at an angle with the fixed plate body, the guide plate body is inclined relative to the fixed plate body, so that the elastic brake can move along a continuous, smooth and natural guide during movement, which helps to reduce the resistance during movement of the elastic brake, thereby improving the reliability of switching the state of the guardrail.

[0012] In an optional embodiment, the rotating plate body is provided with a first mounting hole; the elastic brake is provided with a first fixed part, an elastic part and a brake part, the first fixed part is installed at the first mounting hole, the elastic part is movably installed inside the first fixed part, one end of the brake part is connected with the elastic part, and the other end of the brake part extends away from the first fixed part after being provided in the first mounting hole and facing the rotating plate body.

[0013] Beneficial effects: By providing a first mounting hole on the rotating plate body and installing the first fixed part of the elastic brake member in the first mounting hole, the elastic brake member and the rotating plate body are fixed. Since the elastic brake member also includes an elastic part and a brake part, one end of the brake part is connected to the elastic part, and the other end of the brake part extends away from the first fixed part of the rotating plate body after being provided in the first mounting hole. When the guardrail needs to be unlocked, external force indirectly acts on the elastic part, so that the elastic part stores energy and the brake part is retracted, completing the unlocking of the guardrail and facilitating the rotation and folding of the guardrail. Of course, when the guardrail needs to be locked, the elastic part releases energy, and the brake part can be inserted into the corresponding position to achieve stable locking effect. By setting the brake mechanism of the elastic brake member, the locking and unlocking process of the guardrail is more smooth and efficient.

[0014] In an alternative embodiment, the fixed plate body is provided with a brake hole; when the elastic brake member is in a fixed position, the brake part is used to insert into the brake hole.

[0015] Beneficial effects: By providing a brake hole in the fixed plate body, a locking position is provided for the elastic brake member. That is, when the elastic brake member is in a fixed position, the elastic part releases energy, so that the brake part can be accurately inserted into the brake hole, thereby achieving stable locking between the guardrail and the bed frame, preventing accidental movement or loosening of the guardrail during use, and improving the stability and safety of the overall structure. At the same time, through the insertion and cooperation of the brake part and the brake hole, the caregiver can easily lock the guardrail, simplifying the operation process of locking the guardrail. That is, when the guardrail needs to be locked, the brake part can be inserted into the brake hole by moving the elastic brake member to the fixed position.

[0016] In an alternative embodiment, the elastic brake member further includes a pull button, the pull button is movably installed on the first fixed part, and the pull button is connected to the elastic part. Under the action of external force, the pull button drives the elastic part and the brake part to move away from the fixed plate body until the brake part is separated from the brake hole.

[0017] Beneficial effects: By providing a pull button, the unlocking process of the guardrail can be simplified. That is, by connecting the pull button to the elastic part, the caregiver only needs to apply external force to the pull button to easily drive the elastic part and the brake part to move away from the fixed plate body, so that the brake part is separated from the brake hole, the guardrail is unlocked, and the unlocking operation of the guardrail becomes easy to perform, thereby improving the convenience of operation and reducing the operation steps and time consumption of unlocking, improving the unlocking efficiency of the guardrail.

[0018] In an alternative embodiment, the guardrail comprises a first movable rod, a second movable rod and a crossbar, the first movable rod and the second movable rod are arranged along the length direction of the long side of the bed frame, and the crossbar is directly or indirectly rotatably connected with the first movable rod and the second movable rod at two ends thereof along the length direction; wherein one end of any of the movable rods is rotatably connected with the fixed plate body.

[0019] Beneficial effects: By arranging the first movable rod and the second movable rod along the length direction of the long side of the bed frame, and rotatably connecting the crossbar with the two rods directly or indirectly, and rotatably connecting the two rods with the bed frame, the guardrail can be unfolded or folded as needed. For example, when not in use, the guardrail is folded or retracted to optimize the use of space.

[0020] In an alternative embodiment, when the number of crossbars is at least two, at least two of the crossbars are arranged in the height direction, and one of the crossbars is rotatably connected with the first movable rod and the second movable rod at two ends thereof along the length direction; the guardrail further comprises a connecting rod, the connecting rod is provided with a plurality of rods and is divided into two groups and arranged on the first movable rod and the second movable rod respectively, one end of any of the connecting rods is fixedly connected with the movable rod along the length direction, and the other end of any of the connecting rods is rotatably connected with one of the remaining crossbars.

[0021] Beneficial effects: When the number of crossbars is at least two, the crossbars are arranged in the height direction, forming a multi-layer protective structure at different heights. At the same time, the connecting rods are divided into two groups and arranged on the first movable rod and the second movable rod respectively, and one end of any of the connecting rods is fixedly connected with the movable rod, and the other end is rotatably connected with one of the remaining crossbars, so that the guardrail has a higher flexible movement function.

[0022] In an alternative embodiment, when the number of connecting rods in any group is at least two, the length of one group of connecting rods gradually decreases in the height direction, and the length of the other group of connecting rods gradually increases in the height direction.

[0047] The following is combined Figures 1 to 10 The following describes embodiments of the present invention.

[0048] According to an embodiment of the present invention, in a first aspect, a guardrail structure is provided, such as... Figure 1 As shown, it includes a guardrail 1 and a self-locking component 2.

[0049] The guardrail 1 is installed on the long side (the longer side) of the bed frame 3.

[0050] Specifically, in use, guardrail 1 has the following characteristics: Figure 1 The first fixed state of complete folding is shown, as follows: Figure 2 The second fixed state is fully extended, as shown, and the adjustment state is the transition from one of the first fixed state and the second fixed state to the other.

[0051] In one embodiment, such as Figure 1 and Figure 3 As shown, the self-locking assembly 2 includes a fixed plate 21, a rotating plate 22, and an elastic brake 23.

[0052] The fixed plate body 21 is fixedly installed on the bed frame 3, the rotating plate body 22 is installed on the guardrail 1 and is rotationally connected with the fixed plate body 21, the elastic brake 23 has an initial position when the guardrail 1 is in the first fixed state and a fixed position when the guardrail 1 is in the second fixed state, the elastic brake 23 has a first natural state in the initial position, a second natural state in the fixed position, and a deformation state that is a transition from one of the first natural state and the second natural state to the other.

[0053] By fixing the fixed plate body 21 on the bed frame 3 and rotationally installing the rotating plate body 22 on the guardrail 1, the state of the guardrail 1 can be conveniently switched by using the elastic brake 23 in different states, so that the caregiver can easily adjust the guardrail 1 to the required state as needed without using additional locks or tools to laboriously disassemble or reinstall the guardrail 1, which helps to simplify the process of fixing and unlocking the guardrail 1 and reduce the operation difficulty of the caregiver.

[0054] In one embodiment, as shown in Figure 1 and Figure 3 The self-locking assembly 2 further includes a guide plate body 24 connected with the fixed plate body 21, the guide plate body 24 is in the path of the elastic brake 23 moving from the initial position to the fixed position, and the guide plate body 24 is used to abut against the elastic brake 23.

[0055] By providing the guide plate body 24 in the path of the elastic brake 23 from the initial position to the fixed position, the elastic brake 23 is guided to avoid the situation that the locking fails or is not firm due to deviation, and in the process of the elastic brake 23 following the rotation of the guardrail 1, the elastic brake 23 directly abuts against the surface of the guide plate body 24, making the process of switching the state of the elastic brake 23 more stable and reliable, thereby making the process of switching the state of the guardrail 1 more reliable.

[0056] In one embodiment, as shown in Figure 3 , Figures 5 to 7 The guide plate body 24 is installed at an angle with the fixed plate body 21.

[0057] By installing the guide plate body 24 at an angle with the fixed plate body 21, the guide plate body 24 is inclined relative to the fixed plate body 21, so that the elastic brake 23 can move along a continuous, smooth and natural guide during movement, which helps to reduce the resistance during movement of the elastic brake 23, thereby improving the reliability of switching the state of the guardrail 1.

[0058] When the elastic brake 23 is moved from the initial position to the fixed position, the brake portion 232 of the elastic brake 23 abuts against the guide plate body 24. At this time, since the guide plate body 24 is installed at an angle with the fixed plate body 21, the brake portion 232 gradually acts on the elastic portion to make the elastic portion gradually store energy. When the brake portion 232 moves to the surface of the fixed plate body 21, the brake portion 232 is in a fully stored energy state. When the brake portion 232 moves to the brake hole 211 of the fixed plate body 21, the elastic portion releases energy, so that the brake portion 232 is inserted into the brake hole 211, thereby achieving braking.

[0059] Of course, during the movement of the elastic brake 23 from the fixed position to the initial position, the brake portion 232 is first controlled to abut against the surface of the fixed plate body 21, and then the brake portion 232 is caused to abut against the guide plate body 24. Since the guide plate body 24 is installed at an angle with the fixed plate body 21, the elastic portion gradually releases energy along with the movement of the brake portion 232.

[0060] In an embodiment, as shown in Figures 3 to 7 the rotating plate body 22 is provided with a first mounting hole 221; the elastic brake 23 is provided with a first fixing portion 231, an elastic portion, and a brake portion 232. The first fixing portion 231 is mounted at the first mounting hole 221. The elastic portion is movably mounted inside the first fixing portion 231. One end of the brake portion 232 is connected with the elastic portion. The other end of the brake portion 232 extends away from the first fixing portion 231 after being arranged in the first mounting hole 221.

[0061] By providing the first mounting hole 221 on the rotating plate body 22 and mounting the first fixing portion 231 of the elastic brake 23 at the first mounting hole 221, the elastic brake 23 and the rotating plate body 22 are fixed.

[0062] In addition, since the elastic brake 23 further includes the elastic portion and the brake portion 232, one end of the brake portion 232 is connected with the elastic portion, and the other end of the brake portion 232 extends away from the first fixing portion 231 after being arranged in the first mounting hole 221. When it is necessary to unlock the guardrail 1, an external force indirectly acts on the elastic portion to make the elastic portion store energy and retract the brake portion 232, thereby completing the unlocking of the guardrail 1 and facilitating the rotation and folding of the guardrail 1.

[0063] Of course, when it is necessary to lock the guardrail 1, the elastic portion releases energy, and the brake portion 232 can be extended and inserted into the corresponding position to achieve a stable locking effect. In this way, the locking and unlocking processes of the guardrail 1 are smoother and more efficient by using the braking mechanism of the elastic brake 23.

[0064] In an embodiment, as shown in Figures 3 to 7As shown, the fixing plate body 21 is provided with a brake hole 211; when the elastic brake 23 is in the fixed position, the brake portion 232 is used for inserting in the brake hole 211.

[0065] By providing the fixing plate body 21 with the brake hole 211, a locking position is provided for the elastic brake 23.

[0066] That is, when the elastic brake 23 is in the fixed position, at this time the first mounting hole 221 is coaxial with the brake hole 211, the elastic portion is completely released, so that the brake portion 232 can be accurately inserted in the brake hole 211, thereby realizing the stable locking between the guardrail 1 and the bed frame 3, preventing the accidental movement or loosening of the guardrail 1 during use, and improving the stability and safety of the overall structure.

[0067] At the same time, through the insertion and cooperation of the brake portion 232 and the brake hole 211, the caregiver can easily realize the locking operation of the guardrail 1, and simplify the operation process of locking the guardrail 1.

[0068] That is, when the guardrail 1 needs to be locked, only the elastic brake 23 needs to be moved to the fixed position, so that the brake portion 232 is inserted into the brake hole 211.

[0069] In one embodiment, as shown in Figure 3 and Figure 4 As shown, the elastic brake 23 further includes a pull button 233, the pull button 233 is movably installed on the first fixing portion 231, and the pull button 233 is connected with the elastic portion, under the action of external force, the pull button 233 drives the elastic portion and the brake portion 232 to move away from the fixing plate body 21 until the brake portion 232 is separated from the brake hole 211.

[0070] Through the setting of the pull button 233, the unlocking process of the guardrail 1 can be simplified.

[0071] That is, by connecting the pull button 233 with the elastic portion, the caregiver only needs to exert external force to pull the pull button 233, so as to easily drive the elastic portion and the brake portion 232 to move away from the fixing plate body 21, so that the brake portion 232 is separated from the brake hole 211, realizing the unlocking of the guardrail 1, so that the unlocking operation of the guardrail 1 becomes easy to perform, and the active rod on which the self-locking assembly 2 is located is rotated, thereby improving the convenience of operation, and reducing the operation steps and time consumption of unlocking, and improving the unlocking efficiency of the guardrail 1.

[0072] Preferably, the elastic brake 23 is selected as an internal spring knob type reset pin (hereinafter referred to as a knob type spring reset pin). Among them, the first fixed part 231 is preferably a nut, which is welded on the surface of the rotating plate body 22, and the nut is coaxial with the first mounting hole 221; the elastic part is preferably a spring; the brake part 232 is a pin shaft, which is usually cylindrical and has a certain hardness; the pull button 233 is an operation knob, which is usually made of plastic or metal, and is provided with anti-slip texture or groove; the second fixed part 234 is usually made of metal material, such as stainless steel and carbon steel, and the second fixed part 234 is provided with a cavity inside for installing the spring and other internal parts, and the second fixed part 234 is provided with external threads.

[0073] When installed, one end of the spring along its elastic deformation is connected with the inside of the second fixed part 234, such as clamping, and the other end of the spring along its elastic deformation is fixedly connected with the brake part 232, the second fixed part 234 is threadedly connected with the first fixed part 231, and the pull button 233 is movably arranged opposite to the second fixed part 234.

[0074] In this way, when the elastic brake 23 is in a fixed position, the brake part 232 is inserted into the brake hole 211, and if the guardrail 1 needs to be folded, the caregiver can hold the pull button 233 and pull it out to drive the spring to move, thereby finally realizing the control of the pin shaft in and out.

[0075] In use, when the elastic part is in a fixed position, if the position of the guardrail 1 needs to be adjusted, the pin shaft can be controlled to be separated from the brake hole 211 by pulling out the pull button 233, and the spring stores energy in this process; after the acting force acting on the pull button 233 is removed, the spring releases energy to drive the pin shaft to extend outside the second fixed part 234.

[0076] In one embodiment, as shown in Figure 1 and Figure 2 The guardrail 1 includes a first movable rod 11, a second movable rod 12 and a cross rod 13, the first movable rod 11 and the second movable rod 12 are arranged at intervals along the length direction of the long side of the bed frame 3, and the cross rod 13 is directly or indirectly rotatably connected with the first movable rod 11 and the second movable rod 12 at two ends thereof along the length direction; wherein one end of any movable rod is rotatably connected with the fixed plate body 21.

[0077] By arranging the first movable rod 11 and the second movable rod 12 at intervals along the length direction of the long side of the bed frame 3, and directly or indirectly rotatably connecting the cross rod 13 with the two rods, and rotatably connecting the two rods with the bed frame 3, the guardrail 1 can be unfolded or folded as needed.

[0078] For example, when not in use, the guardrail 1 is folded or contracted to optimize the use of space.

[0079] In one embodiment, when the number of the cross bars 13 is at least two, the at least two cross bars 13 are arranged in a spaced manner in the height direction, and one of the cross bars 13 is rotatably connected with the first movable bar 11 and the second movable bar 12 at two ends thereof in the length direction, respectively. The guardrail 1 further comprises connecting bars 14, and the connecting bars 14 are provided in a plurality and are arranged in two groups on the first movable bar 11 and the second movable bar 12, respectively. Any one of the connecting bars 14 is fixedly connected with the movable bar at one end thereof in the length direction, and the other end thereof in the length direction is used to be rotatably connected with one of the remaining cross bars 13.

[0080] When the number of the cross bars 13 is at least two, the cross bars 13 are arranged in a spaced manner in the height direction, and a multi-layer protection structure is formed at different heights.

[0081] Meanwhile, the connecting bars 14 are arranged in two groups on the first movable bar 11 and the second movable bar 12, respectively, and one end of any one of the connecting bars 14 is fixedly connected with the movable bar, and the other end thereof is rotatably connected with one of the remaining cross bars 13, so that the guardrail 1 has a higher flexible moving function.

[0082] It can be explained that the rotatable connection manner of the cross bars 13 with the first movable bar 11, the second movable bar 12 or the connecting bars 14 is preferably hinged.

[0083] Further, in the above embodiment, the self-locking assembly 2 is installed at one of the first movable bar 11 and the second movable bar 12, and the other one is only rotatably connected with the bed frame 3 through the fixed plate body 21 and the rotating sleeve 25.

[0084] In one embodiment, the self-locking assembly 2 further comprises a rotating sleeve 25, which is used to be rotatably connected with the rotating end of the movable bar, and is rotatably installed on the surface of the fixed plate body 21 through a rotating shaft or the like.

[0085] The surface of the fixed plate body 21 is further provided with a second mounting hole 212, and the rotating shaft is rotatably installed at the second mounting hole 212, and the rotating sleeve 25 is sleeved outside the rotating shaft, so that the rotating sleeve 25 can make a circumferential rotation around the central axis of the rotating shaft.

[0086] Further, the rotating plate body 22 is fixedly connected with the rotating sleeve 25 and rotates with the rotating sleeve 25.

[0087] In one embodiment, when the number of any one of the connecting bars 14 is at least two, the length of one of the connecting bars 14 gradually decreases in the height direction, and the length of the other one of the connecting bars 14 gradually increases in the height direction.

[0088] That is, as shown in FIG. 1, the length of the connecting bar 14 arranged on the first movable bar 11 gradually decreases in the height direction, and the length of the connecting bar 14 arranged on the second movable bar 12 gradually increases in the height direction. Figure 1 andFigure 2 As shown, when the number of connecting rods 14 in each group is at least two, the length of one group of connecting rods 14 gradually decreases from top to bottom, and the length of the other group of connecting rods 14 gradually increases from top to bottom.

[0089] In this way, the parallelogram structure between the cross rods 13 helps to keep the cross rods 13 parallel to each other when the guardrail 1 is switched, reducing structural interference.

[0090] That is, in use, when the guardrail 1 is in the first fixed state, as shown in Figure 1 The connecting rods 14 are parallel to the height direction (vertical direction), and when the guardrail 1 is in the second fixed state, as shown in Figure 2 The connecting rods 14 are parallel to the length direction (horizontal direction) of the guardrail 1.

[0091] According to an embodiment of the present application, on the other hand, the present application also provides a medical bed comprising a bed frame 3 and the guardrail structure provided in the first aspect. Wherein, the guardrail structure is arranged in pairs and respectively installed on the two long side sides of the bed frame 3.

[0092] Because the medical bed comprises the guardrail structure provided in the first aspect, it has the same effect as the guardrail structure, which will not be described here.

[0093] Although the embodiments of the present application are described in conjunction with the drawings, various modifications and changes can be made by those skilled in the art without departing from the spirit and scope of the present application, and such modifications and changes fall within the scope defined by the appended claims.
