Description

Technical Field

[0001] The utility model relates to the technical field of a turnover bed, in particular to a turnover bed with a weighing function. Background Art

[0002] Flip beds are currently widely used in medical care and household occasions. Through the design of a flip bed frame, the bed has the functions of lifting and turning over to meet the patient's treatment needs and daily care needs. In medical care situations, doctors need to measure the patient's weight in time. For bedridden patients with serious conditions or limited mobility, the bed needs to have a weighing function to meet the need for weighing on the bed.

[0003] A flip bed generally includes multiple lifting columns, and weighing sensors are set on the lifting columns to complete the weighing of the bed body. For example, in the Chinese patent literature, patent number CN 2020106563049 disclosed on September 11, 2020, a three-column bed with a weighing function and its supporting structure, the support mechanism includes an upper bed frame, a front column, a first rear column, a second rear column, a front column support mechanism and a rear column support mechanism, the front column support mechanism includes a front weighing sensor, a front flip support mechanism, a first rotating shaft, and a front rotating sliding mechanism, the rear column support mechanism includes a rear weighing sensor, a rear fixed pressure piece, a left and right tilting mechanism, a second rotating shaft, a third rotating shaft, and a rear rotating sliding mechanism, the upper parts of the three columns are fixedly connected with weighing sensors, and the upper ends of the weighing sensors are fixedly connected with fixed pressure pieces. This application completes the lateral flipping of the upper bed frame by coordinating the lifting height of the first rear column and the second rear column.

[0004] The shortcomings of the prior art are that the rear weighing sensors corresponding to the first rear column and the second rear column are arranged along the length direction of the upper bed frame and are located on the outer sides of the first rear column and the second rear column opposite to each other, the weighing sensors are long strips, one end of the weighing sensors is fixed on the column, and the sensor contacts at the other end of the weighing sensors are connected to the upper bed frame, thereby realizing the weighing of the upper bed frame by the weighing sensors. However, when the upper bed frame is flipped laterally, the upper bed frame rotates around the longitudinal axis. Because the flipping direction of the bed frame is perpendicular to the weighing sensors, the pressure generated by the lateral flipping of the upper bed frame on the weighing sensors is converted into a deflection torque of the weighing sensors, causing the installation position and installation direction of the weighing sensors to deflect, thereby reducing the weighing accuracy of the weighing sensors and making it impossible to accurately weigh, affecting the application of flip beds in hospital beds.

[0018] Beneficial effects of the utility model:

[0019] The utility model discloses a turning bed with a weighing function, comprising a bed frame and a transverse turning mechanism, wherein the transverse turning mechanism comprises a first lifting column and a second lifting column arranged along the width direction of the bed frame, a transverse turning axis arranged along the length direction of the bed frame is arranged on the bed frame, the first lifting column and the second lifting column are lifted and lowered in coordination to drive the bed frame to rotate around the transverse turning axis, a first weighing sensor is arranged on the first lifting column, a second weighing sensor is arranged on the second lifting column, a telescopic bracket connected to the bed frame is arranged between the first weighing sensor and the second weighing sensor, the telescopic bracket is extended and retracted as the bed frame rotates, and when the bed frame is transversely turned, the first weighing sensor and the second weighing sensor on both sides of the transverse turning axis are provided with a pressure perpendicular to the axis of the transverse turning axis, the telescopic bracket is connected to the first weighing sensor, the second weighing sensor and the bed frame, the pressure caused by the bed frame is transmitted to the first weighing sensor and the second weighing sensor via the telescopic bracket, and the first detection part in the first weighing sensor is sensitive to the pressure exerted on it The downward pressure can give corresponding pressure feedback, and the second detection part in the second weighing sensor can also give corresponding pressure feedback to the downward pressure it is subjected to. Since the line connecting the first fixing part and the first detection part is perpendicular to the axis of the horizontal flip axis, the pressure caused by the bed frame on the first detection part can be decomposed into a first component force along the line connecting the first fixing part and the first detection part and a second component force perpendicular to the line connecting the first fixing part and the first detection part and pressing down the first detection part after being transmitted through the telescopic bracket. There are no other components of force in the horizontal direction that will cause the first weighing sensor to deflect. Similarly, because the line connecting the second fixing part and the second detection part of the second weighing sensor is also perpendicular to the axis of the horizontal flip axis, the second weighing sensor will not be affected by the component of force in the horizontal direction that will cause the second weighing sensor to deflect, thereby avoiding the influence of the position deflection of the first weighing sensor and the second weighing sensor caused by the horizontal flipping of the bed frame, thereby improving the weighing accuracy of the first weighing sensor and the second weighing sensor.

[0020] Furthermore, a longitudinal flip axis is provided on the telescopic bracket, and the longitudinal flip axis is perpendicular to the transverse flip axis. The bed frame is rotatably connected to the telescopic bracket through the longitudinal flip axis. A longitudinal flip mechanism is provided at one end of the bed frame. The longitudinal flip mechanism includes a third lifting column, a third weighing sensor and a telescopic longitudinal bracket. The third weighing sensor is arranged at the upper end of the third lifting column, and the third weighing sensor is connected to the bed frame through the longitudinal bracket.

[0021] The longitudinal flip mechanism is used in conjunction with the lifting column, so that the bed frame can not only flip in one direction around the transverse flip axis, but also flip in another direction perpendicular to the transverse flip axis around the longitudinal flip axis, thereby improving the ability of the bed frame to flip in all directions and expanding the application range of the flip bed; the first lifting column, the second lifting column and the third lifting column form a triangular positioning cooperation for the bed frame, which can stably support the bed frame without the need for other supporting parts to support the bed frame, and the setting and flipping of the bed frame are relatively convenient.

[0022] Furthermore, one end of the telescopic bracket is rotatably connected to the first load cell and the longitudinal flip axis is parallel to the transverse flip axis, and the other end of the telescopic bracket is slidably hinged to the second load cell and the hinge axis is parallel to the transverse flip axis. When the bed frame deflects laterally, the change in the connection spacing caused by the different heights of the first lifting column and the second lifting column is compensated by sliding the telescopic bracket, and the two ends of the telescopic bracket are respectively rotatably connected to the first load cell and the second load cell, so that the telescopic bracket can rotate together with the flipping of the bed frame, thereby ensuring the stability of the connection between the bed frame and the first lifting column and the second lifting column.

[0023] Furthermore, the first detection part of the first load cell faces the lateral flip axis, and the second detection part of the second load cell faces the lateral flip axis. The first detection part is closer to the straight line where the lateral flip axis is than the first fixed part, and the second detection part is closer to the straight line where the lateral flip axis is than the second fixed part. The force arm of the deflection force caused by the flipping of the bed frame is shorter, which further improves the ability of the load cell to cope with the lateral deflection of the bed frame.

[0024] Furthermore, when the bed frame is in a horizontal state, the first fixing part, the first detection part, the second fixing part and the second detection part are arranged in a collinear manner. The first weighing sensor and the second weighing sensor are arranged in a collinear manner, which is less affected by other factors and the detection result is more reliable.

[0025] Furthermore, the longitudinal support includes a mounting frame and a sliding hinge assembly connected to the mounting frame, the mounting frame is connected to the third load cell via the sliding hinge assembly, and the bed frame and the mounting frame are rotationally connected via a transverse flip axis. To ensure the bed frame's ability to flip around the longitudinal flip axis, the mounting frame and the third load cell are slidingly hinged to compensate for the spacing difference when the bed frame flips around the longitudinal flip axis, forming a universal structure to ensure the stability of the bed frame flipping around the longitudinal flip axis.

[0026] Furthermore, two groups of third weighing sensors are provided, and the two groups of third weighing sensors are respectively located on both sides of the transverse flip axis. The two groups of third weighing sensors cooperate on both sides of the transverse flip axis to provide reliable weighing.

[0027] Furthermore, the second installation frame includes four side panels connected end to end, wherein two opposite side panels are respectively provided with a transverse turning axis connected to the bed frame, and the other two side panels are connected to the third load cell via a sliding hinge assembly. The sliding hinge assembly realizes a reliable sliding connection between the third sensor and the second installation frame.

[0028] Furthermore, a first connecting frame is provided on the first lifting column, the first connecting frame includes a first connecting plate connected to the first lifting column and a first mounting plate whose height is lower than the first connecting plate, and the first weighing sensor is arranged on the first mounting plate. The space occupied by the weighing sensor in the height direction is reduced so that the weighing sensor is not higher than the bed frame and the bed board, and the overall space integration of the flip bed is higher.

[0029] Furthermore, the bed frame includes a connecting rod, which is rotatably connected to the longitudinal flip axis. A positioning plate is provided on the telescopic bracket, which bridges the two ends of the longitudinal flip axis. The positioning plate is provided with a limit plate on the lower side of the longitudinal flip axis. A gap is provided between the limit plate and the connecting rod to accommodate the rotation of the connecting rod so as to limit the rotation angle of the connecting rod and the bed frame around the longitudinal flip axis through the limit plate. The rotation angle of the bed frame is limited by the limit rod to prevent the patient from falling due to excessive rotation of the bed frame, thereby ensuring the safety of the flip bed.

[0030] Furthermore, a plug-in component is provided on the longitudinal flip shaft along the axis of the longitudinal flip shaft, a socket component is provided on the bed frame, a rotating pin is provided between the plug-in component and the socket component, and the plug-in component and the socket component rotate around the rotating pin after being plugged in, and the rotating pin is perpendicular to the bed frame. The setting of the plug-in component and the socket component realizes the plug-in limit, and the rotating pin realizes the rotational cooperation between the two, thereby realizing the rotational cooperation between the longitudinal flip shaft and the bed frame around the rotating pin. When the bed frame flips horizontally, the bed frame and the longitudinal flip shaft can rotate around the rotating pin, thereby reducing the stress between the bed frame and the longitudinal flip shaft, and avoiding the weighing accuracy error caused by the lateral stress generated by the sensor.

[0031] These features and advantages of the present invention will be disclosed in detail in the following specific implementation manners and drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The utility model provides a turning bed with a weighing function, comprising a bed frame and a transverse turning mechanism, wherein the transverse turning mechanism comprises a first lifting column and a second lifting column arranged along the width direction of the bed frame, a transverse turning axis arranged along the length direction of the bed frame is provided on the bed frame, the first lifting column and the second lifting column are distributed on both sides of the transverse turning axis to drive the bed frame to rotate around the transverse turning axis, a first weighing sensor is provided on the first lifting column, a second weighing sensor is provided on the second lifting column, a telescopic bracket connected to the bed frame is arranged between the first weighing sensor and the second weighing sensor, the telescopic bracket is telescopic and retracts as the bed frame rotates, the first weighing sensor comprises a first fixing portion and a first detecting portion of the load-bearing telescopic bracket, the second weighing sensor comprises a second fixing portion and a second detecting portion of the load-bearing telescopic bracket, a line connecting the first fixing portion and the first detecting portion is perpendicular to the transverse turning axis, and a line connecting the second fixing portion and the second detecting portion is perpendicular to the transverse turning axis.

[0053] The flip bed disclosed in the utility model includes a one-way flipping method around a transverse flipping axis, but is not limited to a bed structure that can only flip in one direction, and can also cooperate with other structures to realize flipping of the bed in different directions. In the transverse flipping method disclosed in the utility model, the weighing sensor adopts a bar-shaped pressure sensor, one end of the weighing sensor is a fixed part and is fixed to the lifting column, and the other end is a detection part. The detection part is connected to the telescopic bracket and can withstand the pressure transmitted to the telescopic bracket by the bed frame. The spring piece or contact in the detection part can give feedback to the downward pressure it receives to realize weighing. The pressure generated by the lateral flipping of the bed frame is transmitted downwardly from the bed frame to the telescopic bracket, and the telescopic bracket transmits it to the weighing sensor in the same direction. Taking the first weighing sensor as an example, the direction of the pressure generated by the lateral flipping of the bed frame is perpendicular to the lateral flipping axis. Because the line connecting the first fixed part and the first detection part of the first weighing sensor is also perpendicular to the lateral flipping axis, the pressure on the first weighing sensor can be decomposed into a first component force along the line connecting the first detection part and the first fixed part and a second component force downwardly from the line connecting the first detection part and the first fixed part. There will be no other component force in the horizontal direction that will cause the first weighing sensor to deflect around the first fixed part, and the weighing accuracy of the first weighing sensor is guaranteed. Similarly, because the line connecting the second fixed part and the second detection part of the second weighing sensor is also perpendicular to the lateral flipping axis, the weighing accuracy of the second weighing sensor is also guaranteed.

[0054] The utility model weighs the bed frame and the load thereon by means of a weighing sensor arranged between the lifting column and the bed frame. Since the line connecting the first fixing part and the first detecting part is perpendicular to the transverse flip axis, and the line connecting the second fixing part and the second detecting part is perpendicular to the transverse flip axis, the direction of the flipping force caused by the flipping of the bed frame around the transverse flip axis acting on the installation point is coplanar with the direction of the pressure on the sensor contact on the installation point, preventing the pressure of the flipping force on the sensor contact from causing the sensor contact to deflect around the installation point, thereby ensuring the reliability of the weighing sensor setting and thus ensuring the weighing accuracy of the weighing sensor.

[0055] The "lifting column" referred to in this application, including the first lifting column and the second lifting column, refers to all linear drive mechanisms with lifting functions, including electric cylinders, hydraulic cylinders and air cylinders, etc., and does not specifically refer to a certain type of linear drive mechanism. The function of the lifting column is to lift the bed frame at its position and complete the flipping or lifting of the bed frame.

[0056] In order to ensure the weighing accuracy of the weighing sensor, it is necessary to keep the first weighing sensor and the second weighing sensor in a horizontal state. Therefore, in the present invention, the lower ends of the first lifting column and the second lifting column are fixed, and the first lifting column and the second lifting column are kept vertical to reliably support the bed frame. When the first lifting column and the second lifting column have a height difference to achieve the flipping of the bed frame, the distance between the upper ends of the first lifting column and the second lifting column changes. In order to prevent position interference, a telescopic bracket is designed to adapt to the distance change. The telescopic bracket can be a straight line structure, a folded line structure or other special-shaped structures, and it is only necessary to ensure the telescopic ability of the telescopic bracket in the flipping direction of the bed frame.

[0057] The following is an explanation and description of the technical scheme of the embodiment of the utility model in conjunction with the drawings of the embodiment of the utility model, but the following embodiment is only a preferred embodiment of the utility model, not all. Based on the embodiment in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the utility model.

[0058] In the description of this embodiment, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", "front", "back", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore, cannot be understood as a limitation on the utility model. In addition, if the terms "first", "second", and "third" appear, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0059] Reference Figures 1 to 7 A turning bed with a weighing function proposed in one embodiment of the utility model includes a bed frame 100 and a transverse turning mechanism 200. The transverse turning mechanism 200 includes a first lifting column 21 and a second lifting column 31 arranged along the width direction of the bed frame 100. The bed frame 100 is provided with a transverse turning axis 300 arranged along the length direction of the bed frame 100, that is, the transverse turning axis 300 is parallel to the length edge of the bed frame 100. The first lifting column 21 and the second lifting column 31 are distributed on both sides of the transverse flip axis 300 to drive the bed frame 100 to rotate around the transverse flip axis 300. The first lifting column 21 is provided with a first load cell 22, and the second lifting column 31 is provided with a second load cell 32. A telescopic bracket 41 connected to the bed frame 100 is arranged between the first load cell 22 and the second load cell 32. The telescopic bracket 41 is extended and retracted as the bed frame 100 rotates. The first load cell 22 includes a first fixing portion 23 and a first detecting portion 24 of the load-bearing telescopic bracket 41. The second load cell 32 includes a second fixing portion 33 and a second detecting portion 34 of the load-bearing telescopic bracket 41. The line connecting the first fixing portion 23 and the first detecting portion 24 is perpendicular to the transverse flip axis 300, and the line connecting the second fixing portion 33 and the second detecting portion 34 is perpendicular to the transverse flip axis 300. The pressure of the bed frame 100 is transmitted to the first detection part 24 and the second detection part 34 through the telescopic bracket 41 to form feedback to achieve the weighing of the bed frame 100. The connecting line of the first fixing part 23 and the first detection part 24 and the connecting line of the second fixing part 33 and the second detection part 34 are perpendicular to the horizontal turning axis 300. The bed frame 100 is composed of a plurality of rods. The length direction of the bed frame 100 and the width direction of the bed frame 100 are as follows: Figure 1 The horizontal flip axis 300 is parallel to the length direction of the bed frame 100, and the first lifting column 21 and the second lifting column 31 are arranged along the width direction of the bed frame 100. The flip direction of the bed frame 100 relative to the first fixing part 23 and the first detection part 24, the second fixing part 33 and the second detection part 34 is shown in FIG. Figure 5 As shown. In this embodiment, the first lifting column 21 and the second lifting column 31 both use electric cylinders. The first lifting column 21 and the second lifting column 31 are vertically arranged, and the lower ends of the first lifting column 21 and the second lifting column 31 remain vertically fixed. The first lifting column 21 and the second lifting column 31 are lifted and lowered to realize the rotation of the bed frame 100 around the transverse flip axis 300. When the first lifting column 21 and the second lifting column 31 drive the bed frame 100 to flip, the distance between the upper ends of the first lifting column 21 and the second lifting column 31 is adjusted by the telescopic bracket 41. The bed frame 100 is flipped around the transverse flip axis 300 by the transverse flip mechanism 200. Since the transverse flip axis 300 is arranged along the length direction of the bed frame 100, the flipping of the bed frame 100 around the transverse flip axis 300 can be regarded as the transverse flipping of the bed frame 100.

[0060] The pressure generated by the lateral flipping of the bed frame 100 is transmitted downwardly to the telescopic bracket 41 perpendicularly to the bed frame 100, and the telescopic bracket 41 transmits it to the weighing sensor in the same direction. Taking the first weighing sensor 22 as an example, the direction of the pressure generated by the lateral flipping of the bed frame 100 is perpendicular to the lateral flipping axis 300. Because the line connecting the first fixing portion 23 and the first detecting portion 24 of the first weighing sensor 22 is also perpendicular to the lateral flipping axis 300, the pressure on the first weighing sensor 22 can be decomposed into a first component force along the line connecting the first detecting portion 24 and the first fixing portion 23 and a second component force perpendicular to the line connecting the first detecting portion 24 and the first fixing portion 23 downward. There will be no other component force in the horizontal direction that will cause the first weighing sensor 22 to deflect around the first fixing portion 23, and the weighing accuracy of the first weighing sensor 22 is guaranteed. Similarly, because the line connecting the second fixing portion 33 and the second detecting portion 34 of the second weighing sensor 32 is also perpendicular to the lateral flipping axis 300, the weighing accuracy of the second weighing sensor 34 is also guaranteed.

[0061] In order to improve the stability of the telescopic bracket 41 when the bed frame 100 is turned over, one end of the telescopic bracket 41 is rotatably connected to the first load cell 22 and the longitudinal turning axis 47 is parallel to the transverse turning axis 300, and the other end of the telescopic bracket 41 is slidingly hinged to the second load cell 32 and the hinge axis is parallel to the transverse turning axis 300. This allows the telescopic bracket 41 to avoid interfering with the upper ends of the first lifting column 21 and the second lifting column 31 when the bed frame 100 is turned over. Figure 6 As shown, two parallel connecting plates 42 are respectively provided at both ends of the telescopic bracket 41, and a rotating pin 43 is provided on the connecting plate 42. A first frame 44 is fixedly provided on the first weighing sensor 22, and the first frame 44 cooperates with the rotating pin 43 at one end of the telescopic bracket 41 to realize a rotating connection. A second frame 45 is fixedly provided on the second weighing sensor 32, and a first sliding groove 46 is provided on the second frame 45. The first sliding groove 46 cooperates with the rotating pin 43 at the other end of the telescopic bracket 41 to form a sliding hinge, and the rotating pins 43 at both ends of the telescopic bracket 41 are parallel to the horizontal flip axis 300. When the bed frame 100 is in a horizontal state, the first fixing portion 23, the first detecting portion 24, the second fixing portion 33 and the second detecting portion 34 are arranged in a colinear manner.

[0062] As a simple replacement for the above solution, the telescopic bracket 41 can also be changed from a straight line type to a folded line type or other special-shaped structures.

[0063] The turning bed with weighing function proposed in one embodiment of the utility model is based on the above embodiment. Figures 1 to 3As shown, the telescopic bracket 41 is provided with a longitudinal flip axis 47, and the longitudinal flip axis 47 is perpendicular to the transverse flip axis 300. The bed frame 100 is rotatably connected to the telescopic bracket 41 through the longitudinal flip axis 47. One end of the bed frame 100 is provided with a longitudinal flip mechanism 400, and the longitudinal flip mechanism 400 includes a third lifting column 51, a third weighing sensor 52 and a telescopic longitudinal bracket 61. The third weighing sensor 52 is arranged at the upper end of the third lifting column 51, and the third weighing sensor 52 is connected to the bed frame 100 through the longitudinal bracket 61. The longitudinal flip mechanism 400 cooperates with the transverse flip mechanism 200, so that the bed frame 100 can be flipped around the longitudinal flip axis 47 perpendicular to the transverse flip axis 300, thereby expanding the flip angle of the bed frame 100.

The first connecting frame 25 includes a first connecting plate 26 connected to the first lifting column 21 and a first mounting plate 27 whose height is lower than the first connecting plate 26.

Figure 7 As shown, the two ends of the second connecting plate 36 are bent downward to form two second fixing plates 38 respectively fixed to the second mounting plate 37. Figure 3 and Figure 4 As shown, the two ends of the third connecting plate 56 are bent downward to form two third fixing plates 58 respectively fixed to the third mounting plate 57. Since the first mounting plate 27 and the second mounting plate 37 are provided with weighing sensors on one side, and the weighing sensors are provided on both sides of the third mounting plate 57, the third mounting plate 57 and the first mounting plate 27 are finely adjusted in structure as needed.

[0066] In one embodiment of the present invention, a turning bed with a weighing function is provided, wherein the first detection portion 24 of the first weighing sensor 22 faces the transverse turning axis 300, and the second detection portion 34 of the second weighing sensor 32 faces the transverse turning axis 300. The first detection portion 24 is located closer to the middle of the bed frame 100 than the first fixing portion 23, and the second detection portion 34 is located closer to the middle of the bed frame 100 than the second fixing portion 33, so as to better reduce the influence of the pressure of the turning of the bed frame 100 on the deflection of the weighing sensor.

[0067] In this embodiment, the first weighing sensor 22 and the second weighing sensor 32 are respectively located on one side of the first lifting column 21 and the second lifting column 31 facing the middle position in the length direction of the bed frame 100. As a simple replacement for the above method, the first weighing sensor 22 and the second weighing sensor 32 can also be respectively arranged on the side of the first lifting column 21 and the second lifting column 31 away from the middle position in the length direction of the bed frame 100; or a group of first weighing sensors 22 are respectively arranged on both sides of the first lifting column 21 parallel to the width edge of the bed frame 100, and a group of second weighing sensors 32 are respectively arranged on both sides of the second lifting column 31 parallel to the width edge of the bed frame 100.

[0068] In one embodiment of the present invention, a turning bed with a weighing function is provided. A plug-in component 71 is provided on the longitudinal turning shaft 47 along the axis of the longitudinal turning shaft 47. A socket component 72 is provided on the bed frame 100. A rotating pin 73 is provided between the plug-in component 71 and the socket component 72. After the plug-in component 71 and the socket component 72 are plugged in and matched, they rotate around the rotating pin 73. The rotating pin 73 is perpendicular to the bed frame. For example, Figure 1 and Figure 4 As shown, the plug-in component 71 is a plug-in plate fixed on one side of the longitudinal flip axis 47, one end of the plug-in plate is welded to the longitudinal flip axis 47, and the socket component 72 includes two parallel and spaced socket plates, an open socket slot with two ends connected is formed between the two socket plates, the other end of the plug-in plate is plugged into the socket slot, the width of the socket slot is transitionally matched with the thickness of the plug-in plate, and the plug-in plate and the socket plate are both provided with a receiving hole vertical to the plug-in plate, and the rotating pin 73 passes through the receiving holes of the socket plate and the plug-in plate and is locked at both ends to complete the rotational connection between the socket plate and the plug-in plate. At this time, there is a gap between the end of the plug-in plate away from the bottom of the socket slot, and the gap serves as a rotation margin between the plug-in plate and the socket slot. In addition, in the present embodiment, the side plate of the mounting frame 62 corresponding to the transverse flip axis 300 is provided with a downwardly opening hollow portion on the lower side of the transverse flip axis 300. The hollow portion saves material on the one hand, and on the other hand, the two side surfaces of the mounting frame 62 used to set the transverse flip axis 300 have a certain elasticity, thereby avoiding stress on the third weighing sensor 52 when the bed frame 100 is flipped laterally, thereby improving the reliability of weighing measurement of the bed frame 100.

[0069] The utility model provides a turning bed with a weighing function in one embodiment, such as Figure 8 and Fig. 9 As shown, the bed frame 100 includes a connecting rod 11, which is rotatably connected to the longitudinal flip axis 47. A positioning plate 48 is provided on the telescopic bracket 41 to bridge the two ends of the longitudinal flip axis 47. The connecting plate 42 is fixed on the positioning plate 48, and the connecting plate 42 is perpendicular to the positioning plate 48. The positioning plate 48 is provided with a limiting plate 49 corresponding to the two sides of the longitudinal flip axis 47 on the lower side of the longitudinal flip axis 47. A gap is provided between the limiting plate 49 and the connecting rod 11 to accommodate the rotation of the connecting rod 11 so as to limit the rotation angle of the connecting rod 11 and the bed frame 100 around the longitudinal flip axis 47 through the limiting plate 49. The rotation angle of the bed frame 100 is limited by the limiting rod to prevent the bed frame 100 from rotating too much and causing the patient to fall, thereby ensuring the safety of the flip bed.
