Description

Technical Field

[0001] This utility model relates to the field of medical and nursing equipment technology, and in particular to a lifting structure for the leg surface of a medical bed. Background Technology

[0002] A medical electric bed is a medical bed that uses electricity to achieve multiple functions. It is widely used in hospitals, rehabilitation centers, and home care settings, aiming to improve patient comfort, reduce the burden of care, and promote recovery.

[0003] Existing patent CN202320429378.8 provides a lifting device for an intelligent electric mattress, including a base, a bracket, and a drive mechanism. The bracket includes a first support plate, a second support plate, a third support plate, and a fourth support plate. The first support plate is used to support the upper body of the user, the second support plate is used to support the buttocks, the third support plate is used to support the thighs, and the fourth support plate is used to support the calves. The second support plate is fixedly mounted on the base. The drive mechanism is linked to the first support plate and can drive the first support plate to tilt and rotate. The drive mechanism is also linked to the third and fourth support plates and can simultaneously drive the third support plate to tilt and rotate while driving the fourth support plate to maintain a horizontal lifting motion. This utility model provides a lifting device for an intelligent electric mattress with higher load-bearing capacity and greater comfort.

[0004] A connecting rod (14, 15) is installed between the fourth support plate 5 and the base 1, and a crossbar (12, 13) is fixed between the connecting rod (14, 15). The second electric push rod 604 is installed on the base 1 and below the fourth support plate 5, and is hinged to the crossbar through a hinge seat. Therefore, sufficient height space must be left between the fourth support plate 5 and the ground to accommodate the installation of the second electric push rod 604, the connecting rod (14, 15) and the crossbar. This results in the fourth support plate 5 being relatively high from the ground, occupying a large amount of space during on-site installation, and the connection structure between the second electric push rod 604 and the crossbar having poor stability. In addition, the space between the ground, the base 1 and the fourth support plate cannot accommodate other objects, resulting in significant space waste. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a lifting structure for the legs and bed surface of a medical bed.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is: a lifting structure for the leg surface of a medical bed, the innovation of which lies in: including

[0007] A push rod is horizontally positioned between the ear plate and the drive motor. It has a side waist-shaped hole and a side connecting hole through it on both sides of its length. The side waist-shaped hole is hinged to the ear plate, and the side connecting hole is connected to the output end of the drive motor. A central waist-shaped hole is through it in the middle.

[0008] A support plate, one side of which is pinned to the push rod and the other side is hinged to the thigh bed surface.

[0009] Furthermore, the push rod has a longitudinally arranged pin in the middle of the waist-shaped hole, and the length side of the support plate is connected to the pin.

[0010] Furthermore, the support plate includes a U-shaped structure body, with a first connecting hole at the bottom to accommodate the pin, and a second connecting hole at the top away from the waist-shaped hole on the side to connect to the thigh part of the medical bed. The opening of the U-shaped structure body faces the push rod and can accommodate the push rod to extend in.

[0011] Furthermore, the U-shaped structure body is an integral symmetrical structure, including a first plate segment, a connecting plate segment, and a second plate segment arranged sequentially. The connecting plate segment near the first plate segment and the connecting plate segment near the second plate segment are bent in the same direction to form the U-shaped structure body, and the length of the connecting plate segment is less than the length of the first plate segment. Thus, a groove can be formed between the edge of the first plate segment and the edge of the adjacent connecting plate segment, and between the second plate segment and the edge of the adjacent connecting plate segment, so that the support plate can be raised and lowered smoothly, avoiding interference between the push rod or the thigh bed surface and the support plate. Thus, a first connecting hole and a second connecting hole are opened on both sides of the first plate segment and the second plate segment.

[0012] Furthermore, the push rod is a tubular structure, and a central limiting hole is provided on it between the central waist-shaped hole and the side waist-shaped hole. A shock-absorbing rubber rod is also provided inside the push rod, with one side of the shock-absorbing rubber rod close to the central limiting hole and the other side inside the central waist-shaped hole.

[0013] Furthermore, a plastic washer made of PA66 is provided on the pin between the support plate and the push rod to avoid direct contact between the push rod and the support plate, reduce noise, and extend the structural life. An iron washer and an internal hexagonal pan head screw are also provided on the pin on the outside of the support plate to prevent the push rod from falling off the support plate.

[0014] The advantages of this utility model are:

[0015] In this structure, the push rod is located on both sides of the thigh bed surface and between the ear plate and the drive motor. It is hinged to the ear plate through the side waist-shaped hole and connected to the output end of the drive motor through the side connecting hole. One side of the support plate is pinned to the push rod, and the other side is hinged to the thigh bed surface. Thus, the side waist-shaped hole and the middle waist-shaped hole of the push rod, and the support plate and the thigh bed surface form a triangular structure, which is more stable and has better leg load-bearing capacity. The size of the triangle can be adjusted by pushing and pulling the push rod with the drive motor, thereby realizing the raising and lowering of the bed surface.

[0016] In this structure, the push rod and support plate are installed on both sides of the thigh bed surface. Only enough space is needed between the thigh bed surface and the ground to accommodate the drive motor. This maximizes space utilization, reduces wasted space under the bed surface, and allows the bed surface to be set lower without affecting its normal lifting function, thus improving the safety of the medical bed.

[0017] This structure is novel and ingeniously designed, while also requiring minimal space during installation.

[0018] The support plate has a groove on both sides of its length, which allows the support plate to be raised and lowered smoothly, avoiding interference between the push rod or the thigh bed surface and the support plate.

[0019] A plastic washer, made of PA66, is also provided on the pin between the support plate and the push rod. This washer is used to avoid direct contact between the push rod and the support plate, reduce noise, and extend the structural life. An iron washer and an internal hexagonal pan head screw are also provided on the outside of the pin on the support plate to prevent the push rod from falling off the support plate.

[0020] This structure connects to the thigh bed surface, which reduces swaying or deformation caused by leg movements compared to mounting it on the lower leg bed surface. This improves overall stability and structural stability. At the same time, the thigh bed surface bears a higher proportion of the body weight, which allows for more efficient transmission of driving force, reduces the risk of failure, and enhances the bed surface's load-bearing capacity. Attached Figure Description

[0021] Figure 1 This is an exploded view of the present invention. Detailed Implementation

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] like Figure 1 The illustrated medical bed leg lifting structure includes a push rod 5 and a support plate 6.

[0024] The medical bed includes a bed frame, which is horizontally positioned. From front to back, the top of the bed has an upper body surface, a buttock surface, a thigh surface, and a lower leg surface, with the thigh surface and lower leg surface hinged together. An ear plate is installed in the middle of the bed frame. A drive motor is installed on the bed frame and below the lower leg surface, with its output end positioned horizontally forward.

[0025] This structure is novel and ingeniously designed, while also requiring minimal space during installation.

[0026] This structure connects to the thigh bed surface, which reduces swaying or deformation caused by leg movements compared to mounting it on the lower leg bed surface. This improves overall stability and structural stability. At the same time, the thigh bed surface bears a higher proportion of the body weight, which allows for more efficient transmission of driving force, reduces the risk of failure, and enhances the bed surface's load-bearing capacity.

[0027] In this structure, both the push rod 5 and the support plate 6 are installed on both sides of the thigh bed surface. Only enough space needs to be left between the thigh bed surface and the ground to accommodate the installation of the drive motor. This results in high space utilization, reduces wasted space under the bed surface, and does not affect the normal lifting function of the bed surface while setting the bed surface lower, thus improving the safety of the medical bed.

[0028] The push rod 5 is horizontally positioned between the ear plate and the drive motor, and below the side of the thigh bed surface. It has a side waist-shaped hole and a side connecting hole through it on both sides. The side waist-shaped hole is hinged to the ear plate, and the side connecting hole is connected to the output end of the drive motor. It also has a central waist-shaped hole through it.

[0029] The push rod 5 has a longitudinally arranged pin 4 in the middle of the waist-shaped hole. In this embodiment, the pin 4 is an internally threaded pin 4, and its two ends are drilled and tapped with threads. The length side of the support plate 6 is connected to the pin 4.

[0030] The push rod 5 is a tubular structure with a central limiting hole between the central waist-shaped hole and the side waist-shaped hole. A limiting post is installed in the central limiting hole. A shock-absorbing rubber rod 7 is also provided inside the push rod 5. One side of the shock-absorbing rubber rod 7 is located near the central limiting hole, and the other side is located inside the central waist-shaped hole.

[0031] The shock-absorbing rubber rod 7 is made of urethane. During assembly, it should be inserted into the push rod 5 first. It is used to reduce the impact friction between the internal threaded pin 4 and the push rod 5 when the bed is raised and lowered, thereby increasing the reliability of the structure.

[0032] A plastic gasket 3 is also provided on the pin 4 between the support plate 6 and the push rod 5. The plastic gasket 3 is made of PA66 and is used to avoid direct contact between the push rod 5 and the support plate 6, reduce noise, and extend the service life of the structure.

[0033] The pin 4 is also provided with an iron washer 2 and an internal hex head screw 1 on the outside of the support plate 6. The pin 4 is fixed by the internal hex head screw 1 and the iron washer 2 to prevent the push rod 5 from falling off the support plate 6.

[0034] One side of the support plate 6 is pinned to the push rod 5, and the other side is hinged to the thigh bed surface. The side waist-shaped hole and the middle waist-shaped hole of the push rod 5, and the support plate 6 and the thigh bed surface form a triangular structure. The structure is more stable and the leg load is better. The size of the triangle can be adjusted by pushing and pulling the push rod 5 with the drive motor, thereby realizing the raising and lowering of the bed surface.

[0035] The support plate 6 includes a U-shaped structure body, with a first connecting hole at the bottom to accommodate the pin 4, and a second connecting hole at the top away from the waist-shaped hole to connect to the thigh part of the medical bed. The opening of the U-shaped structure body faces the push rod 5 and can accommodate the push rod 5 to extend in.

[0036] The U-shaped structure body is an integrated symmetrical structure, including a first plate segment, a connecting plate segment, and a second plate segment arranged in sequence. The connecting plate segment near the first plate segment and the connecting plate segment near the second plate segment are bent in the same direction to form the U-shaped structure body, and the length of the connecting plate segment is less than the length of the first plate segment. Thus, a groove can be formed between the edge of the first plate segment and the edge of the adjacent connecting plate segment, and between the second plate segment and the edge of the adjacent connecting plate segment, so that the support plate 6 can be raised and lowered smoothly, avoiding interference between the push rod 5 or the thigh bed surface and the support plate 6. The first plate segment and the second plate segment are provided with a first connecting hole and a second connecting hole on both sides.

[0037] The working principle of this patent:

[0038] When the thigh bed surface needs to be raised, the drive motor is activated, the push rod 5 moves backward, and the top of the support plate 6 pushes the thigh bed surface upward. When the thigh bed surface needs to be lowered, the drive motor is activated, the push rod 5 moves forward, and the top of the support plate 6 pulls the thigh bed surface downward.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
