DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-7 The utility model provides a technical solution: a multifunctional medical bed structure, including a bed body 1, on which a first lying board 2 for supporting the upper body of a patient, a second lying board 3 for supporting the thigh of a patient, and a third lying board 4 for supporting the calf of a patient are arranged, the second lying board 3 is rotatably connected to the side wall of the bed body 1 at one end close to the first lying board 2, the second lying board 3 is rotatably connected to the third lying board 4, and a first lifting component 5 for driving the third lying board 4 to maintain a horizontal state and to drive the second lying board 3 to be synchronously turned over at one end close to the third lying board 4 is arranged below the third lying board 4 and on the bed body 1;

[0023] The first lifting assembly 5 includes two first cross bars 501 symmetrically arranged on the bed body 1 and two second cross bars 502 symmetrically arranged on the lower end surface of the third lying board 4, and the two second cross bars 502 are both connected with sliding cross bars 503 in a sliding manner along the length direction of the second cross bars 502. The first cross bar 501, the second cross bar 502 and the sliding cross bar 503 are arranged in parallel, and a fork shearing piece is arranged between the first cross bar 501 and the second cross bar 502 on the same side. The third lying board 4 is kept in a horizontal state and lifted and lowered by performing a fork-scissor movement in between. The upper end surface of the sliding cross bar 503 is provided with a guide groove with a T-shaped cross section. The cross section of the second cross bar 502 is a T-shaped shape that matches the shape of the guide groove. The sliding cross bar 503 slides on the second cross bar 502. While the third lying board 4 is kept in a horizontal state and lifted and lowered, the position of the third lying board 4 can also adapt to the swing position of the end of the second lying board 3 (that is, the third lying board 4 can move along the length direction of the bed body 1 to adapt to the position of the end of the second lying board 3);

[0024] like Figure 1 , 4As shown, under the lifting action of the first lifting component 5, that is, under the supporting action of the fork scissors, the third reclining board 4 and the second reclining board 3 are lifted to a horizontal state, and in cooperation with the first reclining board 2 in a horizontal state, the patient can lie on the bed body 1 for recuperation. When the patient needs to maintain a semi-kneeling position, the patient lies on the first reclining board 2, the second reclining board 3 and the third reclining board 4. At this time, the first lifting component 5 is controlled to operate, prompting the fork scissors to pull the sliding cross bar 503 to move downward, causing the second cross bar 502 to move downward with the third reclining board 4, and the third reclining board 4 slides downward with one end of the second reclining board 3, as shown in FIG. Figure 2 As shown, the height of the third lying board 4 is lowered relative to the first lying board 2, and the second lying board 3 is in an inclined position. At this time, the patient's upper body is supported on the first lying board 2, the patient's thighs are supported on the second lying board 3, and the patient's calves are supported on the third lying board 4, so that the patient's body can be adjusted from a lying position to a kneeling position and maintain the kneeling position, thereby realizing auxiliary training for the patient in the kneeling position.

[0025] like Figure 5 , 6 As shown, in order to drive the third lying board 4 to perform lifting and lowering movements, specifically, the fork scissors include two cross-arranged support rods 504, the middle positions of the two support rods 504 are hingedly arranged through a rotating shaft, a first slide groove 505 is provided on the side wall of the first cross bar 501, and the length direction of the first slide groove 505 is arranged along the length direction of the first cross bar 501, and a slider 507 is slidably connected inside the first slide groove 505, and a second slide groove 506 is provided on the side wall of the sliding cross bar 503, and the length direction of the second slide groove 506 is arranged along the length direction of the sliding cross bar 503, the lower end of one support rod 504 is hinged to the end of the first cross bar 501, and the upper end is slidably connected to the inside of the second slide groove 506, and the upper end of the other support rod 504 is hinged to the end of the sliding cross bar 503, and the lower end is rotatably connected to the slider 507.

[0026] like Figure 1 , 5 As shown in Figure 6, in order to drive the fork scissors (two support rods 504) to perform fork scissors movement, specifically, a connecting rod 508 is connected between the two sliders 507, and an electric push rod 509 is fixedly installed on the bed body 1, and the end of the output shaft of the electric push rod 509 is fixed to the end of the connecting rod 508. When the electric push rod 509 is running, the output shaft of the electric push rod 509 retracts, so that the output shaft of the electric push rod 509 will rotate with the connecting rod 508, and thus, the connecting rod 508 will carry the slider 507 to slide inside the first slide groove 505. During the sliding process of the slider 507, the two support rods 504 can be driven to perform fork scissors movement, so as to drive the third lying board 4 to rise and fall, and at the same time drive the second lying board 3 to swing.

[0027] like Figure 5-7 As shown, in order to protect the lifting of the third lying board 4, specifically, an oil cylinder 8 is fixedly installed on the side wall of the first cross bar 501, and the piston rod of the oil cylinder 8 extends to the inside of the first slide groove 505 and is fixed on the side wall of the slider 507, and an oil tank 9 is fixedly connected to the bed body 1, and a first oil pipe 10 is fixedly connected to the oil tank 9, and a second oil pipe 11 is connected to the oil cylinder 8, and the second oil pipe 11 is vertically connected to the first oil pipe 10, and the inside of the first oil pipe 10 is slidably connected with a block 13 for adjusting the size of the opening at the connection between the first oil pipe 10 and the second oil pipe 11;

[0028] By rotating the bolt 12, the block 13 is enabled to slide inside the first oil pipe 10, so that the block 13 will block the connecting opening of the first oil pipe 10 and the second oil pipe 11 to varying degrees. In this way, through the flow of oil in the oil cylinder 8 and the oil tank 9, once the first jacking component 5 fails or is damaged, the connecting point between the first oil pipe 10 and the second oil pipe 11 limits the rapid flow of oil, which can slowly lower the third lying board 4, thereby protecting the lifting and lowering of the third lying board 4 and preventing the rapid descent of the third lying board 4 from causing damage to the patient's body.

[0029] like Figure 3 , 4 As shown, in order to prop up the upper body of the patient so that the patient's body position can be adjusted to a sitting position, specifically, one end of the first lying board 2 is rotatably connected to the bed body 1, and the first lying board 2 is flipped upward by the second lifting component 6 to prop up the upper body of the patient, and the second lifting component 6 includes a screw 601 rotatably connected to the bed body 1, as shown in FIG. Figure 4 As shown, the screw 601 is arranged along the length direction of the bed body 1, and a motor 604 is fixedly installed on the bed body 1, and the output shaft of the motor 604 is connected to the end of the screw 601, so that when the motor 604 is started, the output shaft of the motor 604 can rotate with the screw 601, and the screw 601 is connected with a threaded block 602 through threaded engagement, and the threaded block 602 is rotatably connected with a push rod 603, and the upper end of the push rod 603 is hinged on the lower side wall of the first lying board 2. When the screw 601 rotates, the screw 601 can move with the threaded block 602. After the threaded block 602 moves, the push rod 603 can lift the first lying board 2, thereby supporting the upper body of the patient.

[0030] like Figure 1 , 4 As shown, in order to increase the lying comfort of the patient, specifically, the first lying board 2, the second lying board 3 and the third lying board 4 are covered with a nursing pad 7 for increasing the lying comfort.

[0031] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
