Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical devices, and more specifically, it relates to a guardrail connection device for a medical bed. This utility model also relates to a medical bed. Background Technology
[0002] In the field of medical care, bed rails are crucial components for ensuring patient safety and preventing accidental falls. To meet the needs of clinical care, patient transfers, or bed cleaning, bed rails require convenient raising, lowering, or folding functions. Currently, common bed rail connection methods mostly employ simple hinged or pin mechanisms. While these mechanisms are structurally simple, they have revealed many drawbacks in practical use.
[0003] First, traditional hinged connections often lack reliable locking mechanisms or have complex and cumbersome locking structures. When lowering the railing, caregivers may need to perform multiple steps, potentially delaying valuable rescue time in emergencies. Second, many connecting devices, due to poor structural design, cause unnecessary swaying or shifting of the railing during raising and lowering. This not only reduces the stability and safety of the equipment but also, with prolonged use, can lead to loosening or wear of connecting parts due to stress concentration, affecting its lifespan. More importantly, some devices pose a risk of accidental unlocking when locked; that is, under certain external impacts or vibrations, the locking tongue may disengage, causing the railing to suddenly fall, posing a serious safety threat to the patient.
[0004] Therefore, there is an urgent need for a new type of medical bed rail connection device in the existing technology. It can provide a strong and stable support to ensure the absolute reliability of the rail when it is raised, and can also achieve quick and intuitive "one-click" unlocking to improve the efficiency and convenience of nursing operations, thereby fundamentally overcoming the shortcomings of the existing technology in terms of safety, reliability and operability. Utility Model Content
[0005] The purpose of this utility model is to provide a guardrail connection device for a medical bed to solve the technical problems of inconvenient operation and insufficient reliability of existing medical bed guardrails.
[0006] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a guardrail connection device for a medical bed, comprising: The connecting mechanism includes a mounting plate, a first connecting member, and a second connecting member. The mounting plate is used to install a guardrail. The first connecting member has a first hinge shaft at its top that is hinged to the mounting plate and a second hinge shaft at its bottom that is hinged to the medical bed. The second connecting member is located below the first connecting member, and has a third hinge shaft at its top that is hinged to the mounting plate and a fourth hinge shaft at its bottom that is hinged to the medical bed. The first hinge shaft, the second hinge shaft, the third hinge shaft, and the fourth hinge shaft are parallel to each other. The locking mechanism includes a fixed hook, a first locking block, and a second locking block. The fixed hook and the first locking block are fixedly connected and coaxially swaying on the second connecting member. The second locking block is swaying on the second connecting member. The second locking block and the first locking block are sequentially moved. As the first locking block swings away from the medical bed, the fixed hook is disengaged from the first connecting member.
[0007] In one feasible implementation, the locking mechanism includes a first spring and a second spring. The locking mechanism has a first state and a second state. In the first state, the first locking block drives the fixing hook to hook the first connecting member, and the second locking block presses against the first locking block to fix the first locking block. In the second state, the second locking block moves away from the first locking block to release the pressure on the first locking block. The first locking block can swing to release the fixing hook from hooking the first connecting member. The first spring is sleeved on the swing axis of the first locking block and is configured to have a preload force that causes the first locking block to drive the fixing hook in the first state. The second spring is disposed on the second locking block and is configured to have a preload force that causes the second locking block to press against the first locking block.
[0008] In one feasible implementation, the first connector has a fixing rod on the side facing the fixing hook, and in a first state, the fixing hook is hooked onto the fixing rod.
[0009] In one feasible implementation, the guardrail connection device of the medical bed further includes a cover, which covers the side of the second connector opposite to the first connector.
[0010] In one feasible implementation, the body of the second spring is embedded in the second locking block, and along the swing axis of the second locking block, both ends of the second spring extend out from both sides of the second locking block and are respectively connected to the second connecting member.
[0011] In one feasible implementation, both the first connector and the second connector are bent away from the medical bed.
[0012] In one feasible implementation, the protective cover has an operation window corresponding to the first locking block and the second locking block.
[0013] Compared with the prior art, the beneficial effects of the guardrail connection device for the medical bed provided by this utility model are as follows: First, the first and second connecting members in the connecting mechanism are hinged to the mounting plate and the medical bed respectively via the first, second, third, and fourth hinge shafts, forming a parallel four-bar structure that allows the guardrail to swing flexibly. Simultaneously, the fixed hook and the first locking block in the locking mechanism are coaxially and swayably mounted on the second connecting member. The second locking block is swaying on the second connecting member. When the second locking block is moved, the first locking block is released from its locked state and can then be moved to swing away from the medical bed, causing the fixed hook to disengage from the first connecting member. This enables rapid unlocking and separation of the first and second connecting members. Furthermore, the guardrail can change its position relative to the medical bed through the relative movement of the first and second connecting members, thus solving the technical problems of cumbersome operation and inconvenient unlocking of the medical bed guardrail connecting device. In addition, the double locking also solves the problem of guardrail unlocking caused by accidental contact, providing a more stable and reliable guardrail connecting device while addressing the cumbersome operation of traditional medical bed guardrails.
[0014] Secondly, the cooperation of the first and second springs ensures the stability of the connecting mechanism in the locked state and its flexibility after unlocking, thereby improving the technical effect of locking reliability and operational safety, which helps to solve the technical problems of the medical bed guardrail connecting device being unable to lock securely and being easy to loosen and disengage.
[0015] In addition, in the first state, the fixed hook is hooked to the fixed rod, which can provide a stable connection point through the hook-and-hook cooperation between the fixed rod and the fixed hook, thereby enhancing the firmness of the hook, thus enhancing the connection strength and preventing accidental disengagement. It provides a stable locking ability when the guardrail is in a high position, preventing the guardrail from shaking at will when it is in the protective state, so as to solve the technical problem of the connection point of the medical bed guardrail connection device being not firm and easy to shake.
[0016] Furthermore, as an integrated protective shell, the shield physically isolates the internal, intricate linkage mechanism from the complex external operating environment (such as liquid splashes, dust intrusion, or accidental collisions). The design of the operating window achieves a balance between "comprehensive protection" and "direct operation." This invention, by precisely opening windows in the shield, allows users to directly touch the lock buttons for intuitive operation, while the shield itself still fulfills its primary protective function. This fundamentally eliminates the common industry compromise of sacrificing equipment protection levels for convenience. Without affecting any functionality, it significantly improves the long-term durability and reliability of the entire device in harsh environments such as medical settings.
[0017] Another objective of this invention is to provide a medical bed that includes the guardrail connection device described above.
[0018] Compared to existing technologies, the medical bed of this invention possesses all the advantages of the aforementioned guardrail connection device, which will not be elaborated upon here. Furthermore, by integrating the aforementioned connection device, the guardrail is upgraded from a static protective component to a functional module that is linked with the bed body. The direct value of this is to improve the efficiency of nursing work (such as the ability to quickly move the guardrail up and down to facilitate patient transfer) and enhance the patient's sense of security in using the bed independently. Ultimately, it optimizes the overall quality of the medical care environment and the humanized experience. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.
[0023] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, a connection can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.
[0024] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0025] Please refer to the following: Figures 1 to 3 The guardrail connecting device for a medical bed provided by this utility model will now be described. The guardrail connecting device for a medical bed in this application includes a connecting mechanism 1 and a locking mechanism 2. The connecting mechanism 1 includes a mounting plate 11, a first connecting member 12, and a second connecting member 13. The mounting plate 11 is used to install the guardrail. The first connecting member 12 has a first hinge shaft at its top that is hinged to the mounting plate 11, and a second hinge shaft at its bottom that is hinged to the medical bed. The second connecting member 13 is located below the first connecting member 12, and has a third hinge shaft at its top that is hinged to the mounting plate 11, and a fourth hinge shaft at its bottom that is hinged to the medical bed. The hinge shafts, the first hinge shaft, the second hinge shaft, the third hinge shaft, and the fourth hinge shaft are parallel to each other; the locking mechanism 2 includes a fixed hook 21, a first locking block 22, and a second locking block 23. The fixed hook 21 and the first locking block 22 are fixedly connected and are coaxially and swayably disposed on the second connecting member 13. The second locking block 23 is swayingly disposed on the second connecting member 13. The second locking block 23 and the first locking block 22 are sequentially moved. As the first locking block 22 swings away from the medical bed, the fixed hook 21 is disengaged from the first connecting member 12.
[0026] In this embodiment, during specific implementation, the first connecting member 12 and the second connecting member 13 in the connecting mechanism 1 are hinged to the mounting plate 11 and the medical bed respectively via the first hinge shaft, the second hinge shaft, the third hinge shaft, and the fourth hinge shaft, forming a parallel four-bar linkage structure, allowing the guardrail to swing flexibly. Simultaneously, the fixing hook 21 and the first locking block 22 in the locking mechanism 2 are coaxially and swayably mounted on the second connecting member 13, and the second locking block 23 is swayably mounted on the second connecting member 13. When the second locking block 23 is moved, the second locking block 23 releases its fixation to the first locking block 22, allowing the first locking block 22 to... Swinging to the side away from the medical bed causes the fixing hook 21 to disengage from the first connector 12, enabling the first connector 12 and the second connector 13 to be quickly unlocked and separated. Thus, the guardrail can change its position relative to the medical bed through the relative movement of the first connector 12 and the second connector 13, which helps to solve the technical problems of cumbersome operation and inconvenient unlocking of the medical bed guardrail connection device. In addition, the double locking can also solve the problem of guardrail unlocking caused by accidental contact, so as to provide a more stable and reliable guardrail connection device while solving the cumbersome operation of traditional medical beds.
[0027] Based on the above embodiments, in a more preferred embodiment, in order to make the cooperation of the two locking blocks more stable, the locking mechanism 2 includes a first spring 24 and a second spring 25. The locking mechanism 2 has a first state and a second state. In the first state, the first locking block 22 drives the fixing hook 21 to hook the first connecting member 12, and the second locking block 23 presses against the first locking block 22 to fix the first locking block 22. In the second state, the second locking block 23 moves away from the first locking block 22 to release the pressure on the first locking block 22. The first locking block 22 can swing to release the fixing hook 21 from hooking the first connecting member 12. The first spring 24 is sleeved on the swing axis of the first locking block 22 and is configured to have a preload force that causes the first locking block 22 to drive the fixing hook 21 to be in the first state. The second spring 25 is disposed on the second locking block 23 and is configured to have a preload force that causes the second locking block 23 to press against the first locking block 22. With this configuration, this embodiment, through the cooperation of the first spring 24 and the second spring 25, can ensure the stability of the connecting mechanism 1 in the locked state and its flexibility after unlocking, thereby achieving the technical effect of improving locking reliability and operational safety, so as to solve the technical problems of the medical bed guardrail connecting device being unable to lock securely and being easy to loosen and disengage.
[0028] Preferably, the first connector 12 has a fixing rod on the side facing the fixing hook 21. In the first state, the fixing hook 21 is hooked onto the fixing rod, so that a stable connection point can be provided through the hooking cooperation between the fixing rod and the fixing hook 21, thereby enhancing the firmness of the hook, thereby enhancing the connection strength and preventing accidental disengagement. When the guardrail is in a high position, it provides a stable locking ability and prevents the guardrail from shaking randomly when it is in the protective state, thereby solving the technical problem of the connection point of the medical bed guardrail connection device being not firm and easy to shake.
[0029] In one feasible implementation, the guardrail connection device of the medical bed further includes a cover 3, which covers the side of the second connector 13 facing away from the first connector 12. Preferably, in another feasible implementation, the cover 3 has an operating window 31 corresponding to the first locking block 22 and the second locking block 23. As an integrated protective shell, the cover 3 physically isolates the internal precision linkage mechanism from the complex external environment (such as liquid splashes, dust intrusion, or accidental collisions). The design of the operating window 31 achieves a unity of "comprehensive protection" and "direct operation." This invention, by precisely opening a window on the cover 3, allows the user's fingers to directly touch the lock button for intuitive operation, while the cover 3 itself still bears the primary protective responsibility, fundamentally eliminating the common industry compromise of sacrificing equipment protection levels for convenience. Without affecting any function, it significantly improves the long-term durability and reliability of the entire device in the harsh environment of medical settings.
[0030] In one feasible implementation, the main body of the second spring 25 is embedded in the second locking block 23. Along the swing axis of the second locking block 23, both ends of the second spring 25 extend out from both sides of the second locking block 23 and are respectively connected to the second connecting member 13. This embedded layout of the spring strictly restricts the movement trajectory of the elastic element within the locking block, not only eliminating the risk of spring dislocation under violent shaking, but also significantly reducing the overall volume of the locking module with its compact structure. This provides key support for achieving a high-performance layout of the connecting device in the confined space of the medical bed. Of course, connecting both ends of the second spring 25 to the protective cover 3 is also an optional implementation, which will not be elaborated here.
[0031] In one feasible implementation, both the first connector 12 and the second connector 13 are bent away from the medical bed. The unique bending shape of the connector is not a simple change in shape, but rather an active avoidance of the possibility of interference between the guardrail and the edge of the bed or the connecting cable when the guardrail is at its extreme lifting angle through a pre-set physical clearance space. This ensures the smooth and safe movement of the guardrail throughout its entire stroke at the mechanical structure level.
[0032] Based on the same inventive concept, another objective of this utility model is to provide a medical bed that includes the guardrail connection device described above.
[0033] Compared to existing technologies, the medical bed of this invention possesses all the advantages of the aforementioned guardrail connection device, which will not be elaborated upon here. Furthermore, by integrating the aforementioned connection device, the guardrail is upgraded from a static protective component to a functional module that is linked with the bed body. The direct value of this is to improve the efficiency of nursing work (such as the ability to quickly move the guardrail up and down to facilitate patient transfer) and enhance the patient's sense of security in using the bed independently. Ultimately, it optimizes the overall quality of the medical care environment and the humanized experience.
[0034] In summary, compared with the prior art, the above-mentioned connecting mechanism 1 forms a parallel four-bar structure through the first connecting member 12 and the second connecting member 13, allowing the guardrail to swing flexibly. Meanwhile, the locking mechanism 2, through the linkage of the fixing hook 21, the first locking block 22, and the second locking block 23 (specifically: under the action of the second spring 25, the second locking block 23 normally abuts against the first locking block 22 to fix it, while the first spring 24 provides pre-tightening force to the first locking block 22, ensuring that the fixing hook 21 remains firmly hooked; when the second locking block 23 is moved to release the restriction on the first locking block 22...), The first locking block 22, under the linkage, drives the fixing hook 21 to disengage from the fixing rod on the first connecting member 12. Thus, this application can achieve fast and reliable locking and portable unlocking of the guardrail. In addition, the connecting member design that bends away from the bed body avoids movement interference, and the protective cover 3 with operation window 31 protects the internal mechanism while ensuring convenient operation. This achieves a comprehensive technical effect of making the medical bed guardrail connection stable, easy to operate and highly safe. In this way, it can solve the technical problems of traditional medical bed guardrails, such as cumbersome installation and removal, unreliable connection and easy accidental detachment.
[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
