The embodiment of the utility model discloses a medical bed which can realize lifting of the whole bed and adjustment of the posture of the bed body by using a telescopic motor 7. Specifically, the utility model discloses an adjustable lifting medical bed, wherein a bed body comprises an underframe 1 and an upper frame 2, a first connecting piece 3, a second connecting piece 4, a third connecting piece 5, a hinged shaft, a connecting rod 6 and a telescopic motor 7 which are used for the integral lifting of the bed body are arranged between the underframe 1 and the upper frame 2, and the adjustable lifting medical bed is characterized by further comprising: the right base 8 corresponds to the position of the third connecting piece 5 positioned on the right side, the right base 8 is fixedly arranged on the upper surface of the underframe 1, a first sliding groove 801 is horizontally arranged on the front and rear surfaces of the right base, a first sliding rod is arranged at the lower end of the third connecting piece 5, and the first sliding rod extends into the first sliding groove 801 and is in sliding connection with the first sliding groove 801; the articulated piece 9, the articulated piece 9 corresponds to the second connecting piece 4 on the right side in position, the upper end of the articulated piece 9 is articulated with the inner side of the top frame 2, the lower side of the articulated piece 9 is inwards sunken to form a clamping groove 901, the clamping groove 901 comprises an arc-shaped clamping section and a limiting section connected with the clamping section, and the limiting section is vertically arranged; the hinge 9 is provided with a through hole penetrating through the front and rear surfaces; one end of the operating rod 10 is bent and can extend into the through hole; one end of the return spring 11 is fixedly connected with the hinge part 9, and the other end of the return spring 11 is fixedly connected with the top frame 2; the connecting rod 6 penetrates through the front surface and the rear surface of the second sliding chute 601, the second sliding chute 601 is horizontally arranged, the second sliding chute 601 is arranged close to the second connecting piece 4 on the right side, the upper end of the second connecting piece 4 is provided with a second sliding rod 12, and the second sliding rod 12 extends into the second sliding chute 601 and is in sliding connection with the second sliding chute 601.

In this embodiment, still include gag lever post 13, gag lever post 13 sets up in roof-rack 2 right side vertically, and the other end of connecting rod 6 is provided with one or more spacing grooves 1001, and gag lever post 13 can block into in the spacing groove 1001.

The specific working process is as follows:

in a normal state, the top frame 2 is located at the highest position, the second connecting piece 4 located on the right side is located at the rightmost end of the second sliding groove 601 at the moment, the third connecting piece 5 is located at the leftmost end of the first sliding groove 801, and the states of the second connecting piece 4 and the third connecting piece 5 located on the left side are consistent with the states of the right side; the clamping groove 901 below the hinge 9 is clamped on the second sliding rod 12, and the telescopic rod of the telescopic motor 7 is at the longest position.

When the posture of the bed body needs to be changed, and one side is high and the other side is low, the telescopic motor 7 is started, the telescopic motor 7 is contracted, and the left bed body is driven to descend (the structural principle of the part is the same as that of the bed body disclosed by the patent No. 202023314231. X); when the telescopic motor 7 is started, the operating rod 10 is clamped in the limiting groove 1001 (the setting position of the limiting groove 1001 should ensure that the clamping groove 901 is clamped behind the second sliding rod 12 to keep a vertical state and cannot rotate anticlockwise), the second connecting piece 4 cannot move rightwards normally under the influence of the hinge piece 9, and therefore can move leftwards slowly along the second sliding groove 601, at the moment, the second sliding groove 601 gradually becomes low on the left side and high on the right side, the connecting rod 6 can generate thrust on the lower right side to the second connecting piece 4 and the third connecting piece 5 in the change process, the third connecting piece 5 moves rightwards slightly, when the inclination angle of the second sliding groove 601 is larger than that of the third connecting piece 5, the connecting rod 6 is changed into the form that the second connecting piece 4 and the third connecting piece 5 generate thrust on the upper left side, the third connecting piece 5 moves leftwards, and finally changes into the form that the bed body is low on the left side and high side as shown in fig. 1.

It should be emphasized that the operating rod 10 only acts to hinder the movement of the connecting elements and to change the trajectory of the bed, and does not prevent the movement of the connecting elements, and therefore does not damage the telescopic motor 7 and the connecting elements.

In some embodiments, the hinge may be preset to be in a state of being clamped with the second slide bar, and may also find a suitable position to clamp the second slide bar during the descending process of the bed body. When the bed body rises, the articulated elements can be placed at the clamping position in advance by using the operating rod, and when the bed body rises, the second sliding rod is automatically clamped with the clamping groove of the articulated elements. The second sliding rod can also be set to be slightly flexible and can be bent up and down for a short distance, so that space is provided for the hinge joint of the hinge piece.

In this embodiment, when the function that need not use the bed body gesture to change, only use the bed body raising and lowering functions, can withdraw from the action bars, the automatic and articulated elements separation of second slide bar when the bed body descends, the articulated elements receives the right pulling force of spring, can rotate to the position that does not influence each connecting piece and remove, and the bed body can normally go up and down.
