Technical Field

[0001] The utility model relates to the field of guardrails, in particular to a pendulum-type guardrail for a nursing bed. Background Art

[0002] Nursing beds are beds specially designed for use in hospitals and nursing institutions. They are intended to provide a comfortable and safe environment for caring for patients or the elderly in need. They usually have adjustable height, head and foot tilt functions to meet the needs of different patients and nursing operations. Modern nursing beds may also be equipped with additional facilities such as side rails, nursing operation panels and safety alarm systems to improve patient comfort and nursing efficiency. The design considerations of nursing beds include patient safety, convenience and the work efficiency of medical staff, which plays an important role in improving the quality of medical care.

[0003] Nursing bed guardrails are structures installed at the side of the bed to provide safety protection and support for patients. Their main functions include preventing patients from accidentally falling out of bed and providing support and stability for turning over. Modern nursing bed guardrails usually have adjustable height and easy-to-operate designs to facilitate medical staff to perform nursing operations. Guardrail materials are usually selected from lightweight and easy-to-clean plastic or metal to ensure patient comfort and hygiene safety. The use of nursing bed guardrails needs to comply with medical care standards to ensure patient safety and quality of care.

[0004] Currently, nursing beds are composed of a bed body and guardrails. In traditional nursing beds, although the guardrails have a foldable storage function, when they need to be unfolded, they need to manually detent the lock and pull the guardrail upwards to unfold them. This is very inconvenient for patients with hand and foot injuries, who cannot unfold the guardrails by themselves. Therefore, a pendulum-type guardrail for a nursing bed is proposed to solve the above problem. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] Reference Figure 1 - Figure 3 The utility model provides an embodiment of a pendulum-type guardrail for a nursing bed, comprising a guardrail body 1, wherein the guardrail body 1 is internally slidably connected to two connecting blocks 2, the rear side of the connecting block 2 is rotatably connected to a rotating rod 3, the rear side of the rotating rod 3 is fixedly connected to a sprocket 1 4, a chain 5 is meshed between the outsides of the two sprockets 1 4, a shell 6 is rotatably connected between the rear sides of the two rotating rods 3, the inner bottom wall of the shell 6 is fixedly connected to a fixing block 7, the top of the fixing block 7 is fixedly connected to a motor 8, the output end of the motor 8 is fixedly connected to a sprocket 2 9, the sprocket 2 9 and the chain 5 are meshed, a socket 16 is opened inside the connecting block 2, and a fixing assembly is installed inside the guardrail body 1, the fixing assembly is used to facilitate and quickly disassemble and replace the guardrail body 1, the sprocket 1 4 is externally sleeved inside the shell 6, the chain 5 is sleeved inside the shell 6, and the front side of the sprocket 2 9 is rotatably connected to the inner wall of the shell 6.

[0031] Specifically, the guardrail body 1 is the main body of the device and is installed on the nursing bed. The connecting block 2 is used to connect the guardrail body 1 and the rotating rod 3 together. The rotating rod 3 is similar to a crank. The two rotating rods 3 cooperate to keep the guardrail body 1 level during movement. The sprocket 1 4 and the chain 5 cooperate to ensure that the two rotating rods 3 rotate synchronously and will not stagger. The outer shell 6 is installed at the bottom of the nursing bed for connecting and protecting internal parts. The fixing block 7 is used to fix and support the motor 8 to keep the motor 8 stable. The sprocket 2 9 is used to drive the chain 5 to move and drive the rotating rod 3 to rotate. The jack 16 is for facilitating the installation of the guardrail body 1.

[0032] Reference Figure 1 - Figure 3 The fixing component includes two slide grooves 10 and a partition 15. The slide groove 10 is opened inside the front side of the guardrail body 1. The slide groove 10 is slidably connected to the inside of the slide groove 10. The rear end of the handle 11 is fixedly connected to the insertion rod 12. The inside of the insertion rod 12 is fixedly connected to the baffle 13. The outside of the partition 15 is fixedly connected to the inside of the guardrail body 1. A spring 14 is provided between the outside of the partition 15 and the inside of the baffle 13. One end of the spring 14 is fixedly connected to the inside of the baffle 13, and the other end of the spring 14 is fixedly connected to the outside of the partition 15. The insertion rod 12 is slidably connected to the inside of the guardrail body 1, and the outer periphery of the baffle 13 is slidably connected to the inside of the guardrail body 1. The outside of the spring 14 is sleeved inside the guardrail body 1, and the outside of the insertion rod 12 is inserted into the inside of the socket 16.

[0033] Specifically, the slide groove 10 is used to limit the movement direction of the handle 11, ensuring that the handle 11 can only move left and right and will not shake. The insertion rod 12 is used to be inserted into the socket 16 to fix the guardrail body 1. The baffle 13 is used to withstand the thrust from the spring 14 to drive the insertion rod 12 to reset. The partition 15 is used to fix the spring 14 to keep it stable.

[0034] Working principle: When a patient with limited hands and feet wants to change the position of the guardrail body 1, the motor 8 is driven by the remote control. The motor 8 drives the sprocket 2 9 to rotate, so that the chain 5 starts to move, driving the two sprockets 1 4 to rotate at the same time, and the two rotating rods 3 move synchronously. Under the action of the connecting block 2, the guardrail body 1 starts to move, saving time and effort, and easy to operate. When the guardrail body 1 is damaged for some reason, the guardrail body 1 needs to be replaced in time. First, the two handles 11 are limited by the slide groove 10 and moved to the middle synchronously to drive the insertion rod 12 to disengage from the socket 16 on the connecting block 2 to unlock it. Then the guardrail body 1 is pulled out and a new guardrail body 1 is inserted. At this time, the handle 11 is released, and the spring 14 pushes the baffle 13 through the connection of the partition 15, and the insertion rod 12 is ejected and reinserted into the socket 16 to fix it. Then it can be used normally.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
