Description

Technical Field

[0001] The utility model relates to the technical field of physiotherapy bed equipment, in particular to an electric push device with a function of controlling the left - right swing amplitude of a physiotherapy bed. Background Technique

[0002] A physiotherapy bed is a device specifically designed for physical therapy and rehabilitation, and is widely used in hospitals, rehabilitation centers and physiotherapy clinics. Its main function is to help patients relieve pain, restore body functions and promote rehabilitation by providing comfortable support and various massage, traction and other treatment methods.

[0003] The physiotherapy bed can also support a variety of physical therapy methods, such as manual therapy, massage, electrotherapy and traction, etc. Physical therapists can flexibly select appropriate treatment methods according to the specific conditions and treatment goals of patients. For example, during massage or soft tissue treatment, the specific design of the physiotherapy bed enables therapists to apply force better and achieve ideal treatment effects.

[0004] The application scope of the physiotherapy bed is quite extensive. For patients with sports injuries, the physiotherapy bed can help relieve pain and restore the range of motion of muscles; for patients who have been bedridden for a long time, it can assist in rehabilitation training and improve the ability to take care of themselves.

[0005] Some existing advanced physiotherapy beds have multiple movable units such as the head, waist and legs. The waist and leg parts of the bed have functions of moving up and down and flipping left and right. The left - right flipping angles of the waist and leg parts of the bed need to be operated by the operator and are difficult to accurately control. Therefore, when the waist and leg parts of the bed flip left and right, if the flipping angle is too large, the user is likely to fall off the physiotherapy bed, which is a relatively big hidden danger.

[0035] As Figure 1-2 shown is a physiotherapy bed, which includes several main components such as a head unit, a chest unit, a waist unit, and a leg unit. The present utility model is an improvement on the left-right rotation structure of the waist unit and the leg unit.

[0036] As Figures 3-7 shown, the electric push device of the present utility model for controlling the left-right swing amplitude of the physiotherapy bed includes several main components such as a physiotherapy bed waist and leg pad structure 1, a waist and leg pad rotating shaft device 2, a force distribution plate 3, and an electric push device 4.

[0037] The structure of the waist and leg cushion of the physiotherapy bed 1 includes a waist and leg cushion 11 and a mounting plate 12 for the waist and leg cushion. The waist and leg cushion 11 is a combination of a waist cushion and a leg cushion, made of leather wrapped around the outer surface of the sponge. The mounting plate 12 for the waist and leg cushion is installed on the lower surface of the waist and leg cushion 11. The mounting plate 12 for the waist and leg cushion is an integral structure composed of multiple plate units connected to each other. The mounting plate 12 for the waist and leg cushion includes a left mounting plate 12a, a middle mounting plate 12b, a right mounting plate 12c, a front bearing frame 12d, and a rear mounting plate 12e. The left mounting plate 12a, the right mounting plate 12c, the front bearing frame 12d, and the rear mounting plate 12e form a rectangular frame structure and are fixed to the lower surface of the waist and leg cushion 11. The left and right sides of the middle mounting plate 12b are fixedly connected to the left mounting plate 12a and the right mounting plate 12c by screws. Screw holes are also provided at the front and rear sections of the middle mounting plate 12b for fixed connection with the front support 26 and the rear support 27.

[0038] The waist and leg cushion rotating shaft device 2 of the physiotherapy bed includes main structures such as a rotating shaft 21, a bottom plate 22, a retaining liner 23, a front rotating shaft hinge seat 24, a rear rotating shaft hinge seat 25, a front support 26, and a rear support 27. The rotating shaft 21 is fixedly connected to the middle mounting plate 12b through the front support 26 and the rear support 27. The front and rear ends of the rotating shaft 21 are installed in the front rotating shaft hinge seat 24 and the rear rotating shaft hinge seat 25. The structure 1 of the waist and leg cushion of the physiotherapy bed can rotate around the rotating shaft 21. One of the improvement points of the present utility model is that retaining liners 23 are provided on the left and right sides of the bottom plate 22. When the structure 1 of the waist and leg cushion of the physiotherapy bed is horizontal, there is a gap between the upper surface of the retaining liner 23 and the surface of the middle mounting plate 12b. The size of this gap is between 0.5 cm and 1 cm, depending on the width of the bottom plate 22. When the structure 1 of the waist and leg cushion of the physiotherapy bed turns left or right to the end point of its own stroke, the lower surface of the middle mounting plate 12b abuts and cooperates with the corresponding left retaining liner 23 or right retaining liner 23. At this time, the left and right inclination of the structure 1 of the waist and leg cushion of the physiotherapy bed does not exceed 20°.

[0039] The force distribution plate 3 is a vertically hollowed-out plate. The upper end of the force distribution plate 3 is connected to the bottom plate 22, and the lower end is connected to the electric push device 4. The purpose of setting the force distribution plate 3 is to minimize the height of the lower end of the electric push device 4 and make the electric push device 4 more inclined to be vertical.

[0040] The electric driving device 4 is an electric push rod. The main body of the electric push rod is hinged to the electric driving device mounting seat 31 of the force distribution plate 3, and the push rod end of the electric push rod is hinged to the right mounting plate 12c. The lumbar and leg cushion structure 1 of the physiotherapy bed has two support points. One is the rotating shaft 21, which is located at the middle position of the lumbar and leg cushion structure 1 of the physiotherapy bed, and the other is the push rod end of the electric push rod, which is located on the right side of the lumbar and leg cushion structure 1 of the physiotherapy bed. It can be seen that when the lumbar and leg cushion structure 1 of the physiotherapy bed bears pressure, the electric push rod will support the lumbar and leg cushion structure 1 of the physiotherapy bed in the form of a diagonal brace. If the horizontal inclination angle of the electric push rod is small, the force arm of the electric push rod is long, and it is difficult for the electric push rod to support the pressure of the lumbar and leg cushion structure 1 of the physiotherapy bed, resulting in the shaking of the lumbar and leg cushion structure 1 of the physiotherapy bed. The second improvement point of the present invention is that by designing the length of the force distribution plate 3, the horizontal inclination angle of the electric push rod is above 50°, and the optimal horizontal inclination angle is between 60° and 70°.

[0041] When adjusting the left and right flipping of the lumbar and leg cushion structure 1 of the physiotherapy bed in the present invention, only the length of the electric push rod needs to be changed to control the inclination angle of the lumbar and leg cushion structure 1 of the physiotherapy bed.

[0042] The above is only the preferred implementation manner of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present invention should be regarded as the protection scope of the present invention.
