Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a hospital bed that is easy to lift and lower. Background Technology

[0002] A hospital bed is a bed used by patients when they are hospitalized for recuperation and rehabilitation. It is mainly used in major hospitals, township health centers, and community health service centers. Most existing hospital beds have height adjustment functions to make it easier for patients to get up and sit up.

[0003] Patent CN209695617U discloses a conveniently adjustable hospital bed, including a bed frame and a bed board. The bed frame is equipped with a lifting mechanism located below the bed board. The bed board includes a first bed board and a second bed board, which are placed side by side on the bed frame and hinged to each other. The lifting mechanism includes a motor, a drive shaft, and a starter rod. The motor is connected to the drive shaft via gears. One end of the starter rod is fixedly connected to the drive shaft, and the other end is connected to the first bed board via a hinged seat. The bed frame is equipped with a switch that controls the rotation of the motor.

[0004] In the above case, the bed board is raised and lowered by a motor-driven shaft, which in turn drives two starting rods through the meshing of two gears. Due to the limited support structure and lack of auxiliary structures, the adjustable bed board is not sturdy enough and is prone to breakage when the weight above the hospital bed is heavy, resulting in low stability of the device.

[0005] Therefore, this utility model provides a hospital bed that is easy to lift and adjust to meet the needs. Utility Model Content

[0006] The purpose of this invention is to provide a hospital bed that is easy to raise and lower, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a hospital bed that is easy to lift and lower, comprising a base frame, with slide seats fixedly connected to all four sides of the top of the base frame, slide columns slidably connected to the inner side of the slide seats, the top of the four slide columns being fixedly connected to the same bed frame, a locking block fixedly connected to the top of the inner side of the slide seats, a sliding groove for the locking block to slide inside the slide column, a drive rod rotatably connected to the top of the base frame, a plurality of threaded grooves being opened inside the drive rod, four threaded grooves, and a moving block threadedly connected to the outside of each of the four threaded grooves, a rotating rod rotatably connected to the top of each moving block, a limiting rod fixedly connected to the bottom of each moving block, a limiting plate fixedly connected to all four sides of the inner side of the base frame, a limiting groove being opened inside the limiting plate, a limiting rod slidably connected to the corresponding limiting groove, and a side rod fixedly connected to the end of the top of the base frame away from the drive rod.

[0008] In a preferred embodiment, casters with brakes are rotatably mounted on all four sides of the bottom of the base frame, and the outer side of the casters with brakes is provided with anti-slip texture.

[0009] In a preferred embodiment, guardrails are fixedly connected to both sides of the bed frame, and a mattress is placed on top of the bed frame.

[0010] In a preferred embodiment, the two threaded grooves on the left side and the two threaded grooves on the right side of the drive rod are in two sets, and the internal threads of the two threaded grooves in the same set are arranged in opposite directions.

[0011] In a preferred embodiment, there are eight moving blocks and eight rotating rods, with the moving blocks furthest from the drive rod slidably connected to the outside of the side rod.

[0012] In a preferred embodiment, top blocks are fixedly connected to all four sides of the bottom of the bed frame, and two rotating rods located at one end of the top blocks are rotatably connected to the two ends of the bottom of the top blocks.

[0013] In a preferred embodiment, a motor is fixedly connected to one side of the base frame, and the output end of the motor is fixedly connected to the drive rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This utility model, by setting up a drive rod, side rod, moving blocks and rotating rod, enables the device to support the bed frame by driving eight moving blocks and rotating rods through the drive rod and side rod. This gives the device multiple support points, improves the stability of the device, avoids damage due to excessive load, and enhances the practicality of the device.

[0016] This utility model, by setting up a sliding block, a sliding column, a limiting plate, and a limiting rod, allows the outer sliding column to slide within the sliding block when the rotating rod drives the bed frame to rise and fall, providing limiting guidance for the bed frame's rise and fall. Through the cooperation of the locking block and the sliding groove, the connection between the sliding block and the sliding column is strengthened and stabilized, further ensuring the stability of the bed frame. Furthermore, through the cooperation of the limiting groove and the limiting rod inside the limiting plate, the moving block is limited, improving the stability of the moving block.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention; the conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the concept of the present invention are all within the scope of protection claimed by the present invention.

[0024] Please see Figures 1-4This utility model provides a convenient lifting and lowering hospital bed, including a base frame 1. Slide seats 2 are fixedly connected to the top of the base frame 1 around its perimeter. Slide columns 3 are slidably connected to the inner side of each slide seat 2. A bed frame 4 is fixedly connected to the top of the four slide columns 3. A drive rod 5 is rotatably connected to the top of the base frame 1. The drive rod 5 has several threaded grooves 6 inside, with four threaded grooves 6, each threadedly connected to a sliding block 7. A rotating rod 8 is rotatably connected to the top of each sliding block 7. A side rod 13 is fixedly connected to the top of the base frame 1 away from the drive rod 5. The two threaded grooves 6 on the left and the two threaded grooves 6 on the right of the drive rod 5 are in two groups, with the internal threads of the two threaded grooves 6 in the same group arranged in opposite directions. There are eight sliding blocks 7 and eight rotating rods 8. The sliding blocks 7 away from the drive rod 5 are slidably connected to the outside of the side rod 13. Top blocks 9 are fixedly connected to the bottom of the bed frame 4 around its perimeter. Two rotating rods 8 located at one end of the top block 9 are rotatably connected to the two ends of the bottom of the top block 9. A motor is fixedly connected to one side of the base frame 1, and the output end of the motor is fixedly connected to the drive rod 5.

[0025] When the height of the bed frame 4 needs to be adjusted, the motor is started, which drives the drive rod 5 to rotate. The corresponding moving blocks 7 move towards each other through the threaded grooves 6 in the same group, and then the top block 9 is pushed upward by the rotating rod 8 to adjust the bed frame 4 to the appropriate height.

[0026] The drive rod 5 and the side rod 13 work together to synchronously drive the eight moving blocks 7 to work closely together. This design not only ensures the accuracy of transmission, but also greatly enhances the stability of the structure. The moving blocks 7 are connected to the top block 9 at the bottom of the bed frame 4 through the rotating rod 8. This connection method not only simplifies the structure, but also improves the transmission efficiency. It converts the linear motion of the moving blocks 7 into a supporting force on the bed frame 4, and lifts the bed frame 4 through the eight rotating rods 8. The design of multiple support points significantly enhances the load-bearing capacity of the device. Even when facing a large load, due to the large number of support points and their reasonable distribution, the pressure borne by each support point can be effectively distributed, thereby avoiding damage caused by excessive force on a single point.

[0027] Please see Figures 1-4 A locking block 14 is fixedly connected to the top of the inner side of the slide block 2. A sliding groove 15 for sliding the locking block 14 is opened inside the slide column 3. A limiting rod 10 is fixedly connected to the bottom of the moving block 7. A limiting plate 11 is fixedly connected to all four sides of the inner side of the base frame 1. A limiting groove 12 is opened inside the limiting plate 11. The limiting rod 10 is slidably connected to the corresponding limiting groove 12. A caster 17 with brake is rotatably installed on all four sides of the bottom of the base frame 1. The outer side of the caster 17 with brake has anti-slip texture. A guard plate is fixedly connected to both sides of the bed frame 4. A mattress 16 is placed on the top of the bed frame 4.

[0028] When the bed frame 4 moves, it causes the sliding column 3 to slide within the sliding seat 2, and the sliding groove 15 to move outside the locking block 14, thereby limiting the bed frame 4. When the moving block 7 moves, it causes the limiting rod 10 to slide within the corresponding limiting groove 12, thereby limiting the moving block 7.

[0029] The slide block 2 provides a track for the sliding column 3 to slide, allowing the outer sliding column 3 to slide smoothly along the inner wall of the slide block 2 when the bed frame 4 is raised or lowered. This sliding mechanism not only ensures the stability of the bed frame 4 during the raising and lowering process, but also effectively prevents the bed frame 4 from shaking or shifting during the raising and lowering process through physical restriction, thereby greatly improving the patient's sense of security and comfort. The cooperation between the locking block 14 and the sliding groove 15 not only enhances the connection strength between the slide block 2 and the sliding column 3, but also further ensures the stability of the bed frame 4 during the raising and lowering process through a physical locking mechanism. The combination of the limiting plate 11 and the limiting rod 10 not only ensures the stability and accuracy of the moving block 7 during the movement process, but also effectively prevents the moving block 7 from excessive movement or misalignment through physical restriction, thereby ensuring the reliability and safety of the entire raising and lowering mechanism.

[0030] The working principle and usage process of this utility model are as follows: When the height of the bed frame 4 needs to be adjusted, the motor is started, which drives the drive rod 5 to rotate. Through the threaded groove 6 of the same group, the corresponding moving blocks 7 move towards each other. Then, the rotating rod 8 pushes the top block 9 upward to adjust the bed frame 4 to a suitable height. When the bed frame 4 moves, it drives the sliding column 3 to slide in the sliding seat 2, and the sliding groove 15 moves outside the locking block 14, thereby limiting the bed frame 4. When the moving block 7 moves, it drives the limiting rod 10 to slide in the corresponding limiting groove 12, thereby limiting the moving block 7.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
