Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of physiotherapy bed equipment, in particular to a double-cylinder lifting structure of a waist and leg pad assembly of a physiotherapy bed. Background Art
[0002] A physiotherapy bed is a medical device specifically used for physical therapy and rehabilitation, mainly used to improve the physical condition of patients, relieve pain, and promote recovery. It combines the advantages of modern medicine and traditional therapies to provide patients with a comfortable and effective treatment experience.
[0003] The design of a physiotherapy bed usually takes into account ergonomics, can adapt to different body shapes and postures, and enhance the treatment effect. This kind of bed usually has adjustment functions and can be adjusted in height and inclination angle according to the needs of patients, so as to facilitate the operation and treatment of doctors and therapists. The surface material of the physiotherapy bed generally uses soft and easy-to-clean materials to ensure hygiene and comfort.
[0004] As Figure 1-2 shown in the existing physiotherapy bed structure, it can be seen from the figure that a single cylinder is used to lift or lower the waist and leg pad of the existing physiotherapy bed. The cylinder is located at the midline position of the waist and leg pad of the physiotherapy bed. In actual use, it is found that when a patient lies on the physiotherapy bed, they often do not lie exactly in the middle but have a certain left-right inclination, resulting in the force exerted by the waist and leg pad of the physiotherapy bed on the cylinder not being coaxial with the cylinder axis. The connection between the cylinder axis and the waist and leg pad fixing plate structure is extremely easy to be damaged under the action of shear force, resulting in frequent maintenance of the physiotherapy bed. Content of the Utility Model
[0005] The technical problem to be solved by the utility model is to provide a double-cylinder lifting structure of a waist and leg pad assembly of a physiotherapy bed aiming at the deficiencies of the above-mentioned existing technologies. This double-cylinder lifting structure can effectively improve the connection stability between the cylinder and the waist and leg pad fixing plate, and improve the service life of the physiotherapy bed.
[0006] To achieve the above technical purpose, the technical solution adopted by the utility model is as follows:

The rear end of the waist and leg pad fixing plate structure is connected to the upper end of a force distribution plate. A distribution plate hinge point is respectively arranged on the left and right parts of the lower end of the force distribution plate. Each distribution plate hinge point is respectively connected to a cylinder lifting unit. The cylinder lifting unit is installed on the physiotherapy bed base. The physiotherapy bed base is placed on the ground. The cylinder lifting unit can push the force distribution plate to drive the rear end of the waist and leg pad fixing plate structure to move up and down.
[0008] To optimize the above technical solution, the specific measures taken also include:
[0009] The waist and leg pad of the above physical therapy bed includes a lumbar and hip pad and a leg pad. The leg pad is located behind the lumbar and hip pad. The lumbar and hip pad is fixedly connected to the front half of the structure of the waist and leg pad fixing plate, and the leg pad is fixedly connected to the rear half of the structure of the waist and leg pad fixing plate.
[0010] The above-mentioned structure of the waist and leg pad fixing plate includes a top plate, a front hinge seat, a rear hinge seat, a hinge shaft, a front connection seat, a rear connection seat and a bottom plate. The front hinge seat and the rear hinge seat are respectively fixed on the upper surface of the bottom plate. The front end of the hinge shaft is hingedly connected to the front hinge seat, and the rear end of the hinge shaft is hingedly connected to the rear hinge seat. The hinge shaft can rotate relative to the front hinge seat and the rear hinge seat. The front connection seat and the rear connection seat are respectively fixedly connected to the front and rear parts of the hinge shaft. The lower surface of the top plate is fixedly connected to both the front connection seat and the rear connection seat at the same time. The waist and leg pad of the physical therapy bed is fixedly connected to the top plate. The front end of the bottom plate is hinged to the support structure, and the rear end is connected to the upper end of the force distribution plate.
[0011] The above-mentioned structure of the waist and leg pad fixing plate is made of stainless steel material.
[0012] The above-mentioned force distribution plate is a trapezoidal plate. The main body of the force distribution plate is vertically arranged. The hinge point of the distribution plate includes a horizontal foot plate and a cylinder connection hinge seat. The horizontal foot plate is integrally formed with the main body of the force distribution plate, and the cylinder connection hinge seat is fixed on the lower surface of the horizontal foot plate.
[0013] Reinforcing ribs are arranged at the connection between the main body of the above-mentioned force distribution plate and the horizontal foot plate.
[0014] The above-mentioned cylinder lifting unit includes a cylinder main body, a cylinder base and a cylinder telescopic shaft. The cylinder main body is fixedly installed on the cylinder base. The cylinder telescopic shaft is telescopically connected to the cylinder main body. The cylinder telescopic shaft is also hingedly matched with the cylinder connection hinge seat. The cylinder base is connected to the base of the physical therapy bed. The cylinder main body can push the force distribution plate to move up and down through the cylinder telescopic shaft.
[0015] The lower end of the above-mentioned base of the physical therapy bed is provided with rollers or support feet.

[0018] The present utility model has the following advantages:
[0019] The utility model changes the single motor in the prior art to left and right dual motors. Each motor bears half of the load of the waist and leg pads of the physiotherapy bed, which can effectively reduce the load borne by the connecting parts between the motor and the force distribution plate and prevent the connecting parts from being damaged due to excessive loads.
[0020] The utility model adds a force distribution plate, which is a trapezoidal plate. The upper part of the trapezoidal plate is structurally connected to the fixing plate of the waist and leg pads. The width of the upper end of the trapezoidal plate enables the trapezoidal plate and the fixing plate of the waist and leg pads to have a relatively long connecting belt in the left-right direction. Therefore, it can effectively disperse the pressure of the fixing plate of the waist and leg pads on the force distribution plate and prevent the upper end of the force distribution plate from being damaged. At the same time, the force distribution plate can distribute the pressure conducted by the fixing plate of the waist and leg pads relatively evenly to the left and right sides at the lower end of the trapezoidal plate, that is, the connection points of the two motors, so that the left and right dual motors bear similar loads and there will be no problem that one motor bears a large pressure and the other motor bears a small pressure.

[0033] As Figures 3-5 shown, there is a physiotherapy bed. The rear half of the physiotherapy bed is the waist and leg physiotherapy area. The double-cylinder lifting structure of the waist and leg cushion assembly of the physiotherapy bed of the present utility model is used for the up and down movement of the waist and leg physiotherapy area of the physiotherapy bed.
[0034] From Figures 1-5 it can be seen that the waist and leg physiotherapy area of the physiotherapy bed has a certain width. When the user sits on the physiotherapy bed, the center of gravity may be located on the left side of the physiotherapy bed or on the right side of the physiotherapy bed. These eccentric pressures will act on the bearing points of the cylinder lifting unit 4, resulting in easy damage to the bearing point connecting member of the cylinder lifting unit 4 (i.e., the force transmission connecting member at the upper end of the cylinder telescopic shaft 43). To solve this problem, the present utility model improves the existing cylinder lifting unit.
[0035] As Figure 6 shown, the double-cylinder lifting structure of the waist and leg cushion assembly of the physiotherapy bed of the present utility model includes a physiotherapy bed waist and leg cushion 1, a waist and leg cushion fixing plate structure 2, a force distribution plate 3, two cylinder lifting units 4, a physiotherapy bed base 5 and a support structure 6.

The horizontal foot plate 31a is integrally formed with the main body of the force distribution plate 3, and the cylinder connection hinge seat 31b is fixed on the lower surface of the horizontal foot plate 31a.
[0039] The number of the cylinder lifting units 4 is two, which are arranged one on the left and one on the right. The left and right cylinder lifting units 4 have exactly the same structure. The cylinder lifting unit 4 includes a cylinder main body 41, a cylinder base 42 and a cylinder telescopic shaft 43. The cylinder main body 41 is fixedly installed on the cylinder base 42.

[0040] The support structure 6 includes a support rod 61 and a support rod seat 62. There are two left and right support rod seat hinge ears 63 arranged on the support rod seat 62. A support rod seat rotating shaft passes through the two support rod seat hinge ears 63 at the same time and is rotatably matched with the two support rod seat hinge ears 63. The front end of the bottom layer plate 27 is fixed on the support rod seat rotating shaft. The lower end of the support rod 61 is fixed to the physiotherapy bed base 5, and the upper end is fixed to the support rod seat 62.
[0041] The double-cylinder lifting structure of the waist and leg pad assembly of the physiotherapy bed of the present utility model lifts the waist and leg pad assembly of the physiotherapy bed in the following manner: When it is necessary to lift the rear end of the waist and leg pad 1 of the physiotherapy bed, the cylinder lifting unit 4 is started, the cylinder telescopic shaft 43 extends out, the force distribution plate 3 moves upward, so that the entire waist and leg pad fixing plate structure 2 rotates around the support rod seat rotating shaft, and further the rear end of the waist and leg pad 1 of the physiotherapy bed is lifted.
[0042] The above are only the preferred embodiments of the present utility model, and the protection scope of the present utility model is not limited to the above embodiments. All technical solutions falling within the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that for those of ordinary skill in the art, several improvements and refinements made without departing from the principle of the present utility model shall be regarded as falling within the protection scope of the present utility model.
