The working process of the invention is as follows:

it should be noted that the existing transfer bed comprises a movable bed body and a transfer bed board for bearing a patient, wherein rollers are arranged at the bottom of the transfer bed board and are matched with a preset track at the top of the bed body. The transfer bed belongs to a carrier device which is already used in the prior art.

When the ultrasonic bed is used, the two transfer devices are respectively clamped with the two ends of the length direction of the existing ultrasonic bed body: inserting the B-ultrasonic bed body between the middle mounting plate and the lower mounting plate of the fixing frame, and then rotating the hand-screwing bolt to enable the hand-screwing bolt to prop against the bottom surface of the B-ultrasonic bed body, so that the connection between the transfer device and the B-ultrasonic bed body is realized;

due to the elastic action of the scroll spring, the transmission shaft, the transmission wheel connected with the transmission shaft, the transmission belt driven by the transmission wheel, the slide bar connected with the transmission belt through the clamp and the wing plate connected with the slide bar through the connecting plate are forced to maintain the following states: the slide bar of each transferring unit is positioned in the top notch of the U-shaped notch, the slide bar of the outermost supporting mechanism is propped against the end part of the top notch of the U-shaped notch, the wing plates of all supporting mechanisms on each transferring unit are butted and flush with the top surface of the bracket, and the wing plates on two adjacent transferring units are butted and aligned. Thus, the wing plates of all the transfer units form a flat channel.

The transfer bed board loaded with patients is moved to the transfer units of the two transfer devices by the rollers at the bottoms of the two ends of the bed, and the length and the width of the B-ultrasonic bed are prolonged in practice due to the existence of the transfer devices, so that the phenomenon that the existing transfer bed board cannot be transferred due to the fact that the length and the width of the B-ultrasonic bed body are larger than those of the B-ultrasonic bed body is avoided.

When the transferring bed plate moves to the wing plates of the two transferring devices, the transferring bed plate is askew, and is not in a normal detection position, so that medical staff is required to carry out non-sitting position detection such as body exploring and the like during B ultrasonic detection (because the medical staff needs to keep a handheld probe for detection and the other hand needs to control a B ultrasonic machine to observe and the like), and the transferring bed plate is required to be repeatedly moved to correct the detection position. To solve this problem, the present invention operates as follows:

firstly, remove the regulating block along the regulating tank, the regulating block drives the motor cabinet and the transmission motor on the motor cabinet removes along the regulating tank, and make the output and the connecting sleeve of transmission motor insert and join in marriage, then start the transmission motor, the output of transmission motor drives connecting sleeve and transmission shaft rotation, the transmission shaft overcomes spiral spring elasticity and drives the drive wheel of every transport unit and rotate, and then make the drive belt rotate, because the drive belt passes through the clamp to be connected with every supporting mechanism's slide bar, and the drive belt passes through the connecting block and is connected with the slider bottom surface, so the rotation of drive belt can drive the slider and make the removal that is close to the baffle along the notch on the dog, simultaneously the drive belt can also drive every supporting mechanism's slide bar and remove along U type breach, until the slide bar top of inside supporting mechanism is supported in the bottom breach tip of U type breach, at this moment all supporting mechanism's slide bars all are located the bottom breach of U type breach, simultaneously in-process, the slider drives the push pedal towards the baffle and removes, when the gyro wheel of bed board contact transport, can promote the gyro wheel to remove until two gyro wheels of transport tip are pressed from the clamp between push pedal and baffle, this moment transport the baffle all pastes the corresponding baffle, the position of the bed of the transport board and is just to the bed has just been just transferred to the bed to the normal position of the bed that is just so to the detection, the bed has been realized.

In addition, the movement of each supporting mechanism in the whole process actually realizes the downward movement of the wing plate, and compared with the operation that the supporting mechanism does not displace and the push plate is directly adopted to push the rollers of the transfer bed plate, the friction force born by the rollers in the whole displacement is greatly reduced, and the vibration possibly generated by the transfer bed plate is further reduced. Of course, it should be noted that the width of the notch on the stopper of the bracket is smaller than the radius of the roller of the transferring bed board, the specific size and the overall height of the transferring device can be designed according to the actual requirement (the height of the B ultrasonic bed body and the height of the transferring bed board on the transferring bed), and of course, for some transferring beds with simpler structures in the prior art, when the transferring bed board is moved to the transferring device, the transferring bed board still needs to be lifted manually by a small margin so as to separate the transferring bed board from the track. However, the magnitude of this motion is small and the receiving of the rotating device has a negligible effect on the patient.

The plug-in key arranged on the output end of the transmission motor is mainly used for clamping the plug-in block after the plug-in key is inserted into the connecting sleeve, so that the rotation of the output shaft of the transmission motor is converted into the rotation of the connecting sleeve and the transmission shaft. In order to prevent the following problems: when the output end of the transmission motor is inserted with the connecting sleeve, the insertion key and the insertion block are positioned on the same straight line, so that the insertion block cannot be inserted or even is crushed by the insertion key. The invention adopts the arrangement that the plug-in block is an elastic block and the displacement compensation notch is arranged on the connecting sleeve, when the situation occurs, the plug-in block is forced to deform by inserting the plug-in key, and part of the block of the plug-in block moves into the displacement compensation notch, so that the damage of the plug-in block can not be caused, and when the output end of the transmission motor rotates, the plug-in key generates circumferential displacement, so that the plug-in block resets under the self elastic action, is clamped with the plug-in key and is driven by the output end of the transmission motor.

After the B ultrasonic detection is finished, starting a transmission motor to reversely rotate, so that the sliding block drives the push plate to be far away from the baffle plate for resetting operation, and then moving the transfer bed plate to a movable bed body upper track; or when the elasticity coefficient of the scroll spring is large enough, the transmission motor is directly closed, the output end of the transmission motor is separated from the connecting sleeve, the scroll spring drives the transmission shaft, the transmission wheel, the transmission belt and the corresponding supporting mechanism to reset under the self elasticity effect, and then the transfer bed board is moved to the movable bed body to orbit.

Compared with the prior art, the invention has the following advantages: the ultrasonic B-ultrasonic detection device is reasonable in overall structural design, can realize the transportation of patients only by operating the driving motor, is simple and rapid to operate, and can not cause secondary damage to the patients due to small vibration generated in the whole process, so that the working efficiency of the B-ultrasonic detection is greatly improved.
